MySQLを、PostgreSQLとは別の実装としてサポートする。初期リリースの範囲外。方言をまたぐ共通DSLは作らない（作った瞬間にSQLをDSLに翻訳させる形に戻る）。代わりにプラットフォームごとに、そのDBの構文と型規則を実装したアナライザーと、そのDBのdumpを使うマイグレーション支援を持つ。共有するのはテンプレートの展開、`go/analysis`のフロントエンド、Go側の型照合の枠組み - ライセンスと構成（裁定 2026-09-09、改訂）: MySQLサーバはGPLv2で、Apache 2.0のsqlshapeと同じ成果物には混ぜられない（libpg_queryの形が成立したのはPostgreSQL Licenseが寛容だったから）。守るのは「利用者のランタイムにGPLが混入しない」の1点で、優先するのは利用者の使いやすさ。MySQLとPostgreSQLで別のバイナリを使い分けさせることはしない。そこでモノレポの中でモジュールを2種に分ける。① Apache 2.0のまま残るもの: 利用者のコードにリンクされる`sqlshape`（ランタイム）と`pgtest`、`pgtest`が使うPostgreSQL側の解析（`internal/analyze` / `schema` / `catalog` / `pgparse` / `oracle` / `verify`）、テンプレート展開、義務、vetのフロントエンド。import pathは`github.com/kr9ly/sqlshape`のまま動かさない。② GPLv2に置くもの: MySQLの文法・字句解析器・関数表を切り出したwasmとそのアナライザー（`github.com/kr9ly/sqlshape/mysql`、ネストしたモジュール）、そして両方を積む1つのバイナリ`cmd/sqlshape`（ネストしたモジュール、GPLv2。Apache→GPLの一方向importは互換）。バイナリは`schema.sql`の宣言（`-- sqlshape: postgres 18` / `-- sqlshape: mysql 8.4`）で方言を選び、vetとしてもマイグレーションとしても同じ1つで済む。利用者のアプリにリンクされるのは①だけなので、GPLは開発ツールに閉じる（gccと同じ）。`internal/`の参照はパスの接頭辞で判定されるのでネストしたモジュールからも通る見込みだが、これとネストしたモジュールのタグ付け（`cmd/sqlshape/vX.Y.Z`）と`go install`の解決はスパイクで確認する。退けた案: MySQL対応を別リポジトリ・別バイナリ`sqlshape-mysql`にする（当初の裁定。利用者にDBごとのバイナリを使い分けさせることになる）、パーサを別プロセスにしてパイプで木を渡す（FSFは密なデータ交換を結合とみなし得るとしていて灰色、構造も歪む）、Apache 2.0の互換パーサ（TiDB parser / Vitess）を使う（原則を捨てる）、抽出を事実に限定して文法を手書きする（一番品質が欲しい文法が手書きになる） - パーサと字句解析器（裁定 2026-09-09）: MySQLサーバのソースから機械的に切り出し、libpg_queryと同じ形でwasmにする。原則は「本物から機械的に抽出したものを土台にし、手で書く部分を最小にする」。文法は`sql/sql_yacc.yy`（bison、18k行、`%expect 59`）からC++のアクション（`NEW_PTN`が923箇所）を剥がして規則・優先順位・トークンだけを残し、規則名と子要素だけの素の構文木（CST）を組む汎用アクションを機械生成してbisonに通す。字句解析器は`sql/sql_lex.cc`の`lex_one_token`（726行）と2トークン先読みの`MYSQLlex`（`WITH ROLLUP`等の合成）、`Lex_input_stream`（440行）、`find_keyword`（`sql/lex.h`の784語の表から`gen_lex_hash`が生成する完全ハッシュ）、`consume_comment`・`int_token`をそのまま使う。測ったところ、字句解析器がサーバ状態を読むのは5点だけ — `sql_mode`（`ANSI_QUOTES`の1箇所）、`default_collation_for_utf8mb4`、接続文字集合、コメント収集の`m_parser_state`、非推奨文字集合の`push_warning`（2箇所）— なのでTHDはこの5点を持つ数十行のshimで置き換える。文字の分類（`state_map` / `ident_map`）は`strings/sql_chars.cc`が文字集合のctype表から作るもので、`strings/`ライブラリごと取り込む（PGの`src/port`をlibpg_queryが抱えるのと同じ）。バージョンコメント`/*!80000 ... */`は`MYSQL_VERSION_ID`との比較なので、版ごとにビルドすれば自然に正しい。sqlshape用のASTへの変換だけが手書きで、CSTの規則名を読む。生成手段はこの裁定でbison + emccに決まる（goyaccでpure Goに持つ案は字句解析器の書き直しを伴うので原則に反する）。残る確認はスパイク: shimの表面積が本当に5点で閉じるか、抽出した文法とlexerがemccで通るか、`mysql-test/t`（1810ファイル）の受理率 + - スパイクの結果（2026-09-09、`mysql/spike/`）: 三点とも成立。shimの表面積は5点で閉じた（警告・digest・utf8本文・オプティマイザヒントは空実装）。アクションを剥がした文法はbison 3.8で`%expect 59`のまま通り、トークン番号は本物と一致する。`mysql-test/t`の1,455ファイルを文に割った137,062文のうち、エラーを期待しない125,187文の99.89%を受理し、残りはテストハーネス側の事情（delimiter、クライアント文字集合の切り替え、パーサ深さの試験）で文法の穴は見つかっていない。MySQLがアクション内で出す構文エラー（予約関数名のテーブル名、`<=>ALL`）はCSTパーサでは通るので、意味層で拾う + - 文字集合レジストリ（裁定 2026-09-09）: `strings/`の照合ライブラリを丸ごとリンクする（ctype-*.cc、collations*.cc、`uca9dump`が生成するzh/jaの重み表）。wasmは4.6MBで、名前だけの表なら0.9MBだが、手で持つ表をゼロにすることと、型層でPAD SPACE・mbmaxlen・既定照合を参照するときにレジストリがそのまま答えになることを優先した。サイズが問題になったら重み表（`uca900_data.h`とhan表、約3MB）だけを空にする - `sql_mode`は判定を変えるので、版と同じくschema.sqlが宣言する（`-- sqlshape: mysql 8.4 sql_mode=...`の形は未決）。字句では`ANSI_QUOTES`、文法のアクションを剥がすので`PIPES_AS_CONCAT`（`||`）の意味はCST→ASTの変換で`sql_mode`を見て決める - オプティマイザヒント（`/*+ ... */`）は別の文法`sql/sql_hints.yy`（725行）と`Hint_scanner`を持つ。同じ手順で後から足せる。sqlshapeの判定には効かないので初期は読み飛ばす - カタログ（裁定 2026-09-09、測定に基づく）: MySQLには`pg_proc`に当たる表がないが、組み込み関数の定義はソースにまとまっていて機械抽出できる。①関数表`sql/item_create.cc`の`func_array`（347エントリ）: 名前 → Itemクラス × 引数個数（固定 / 最小・最大 / 偶奇）。②キーワード構文の関数（`CAST`・`TRIM`・`DATE_ADD`等、81クラス）は`sql_yacc.yy`のアクションの`NEW_PTN Item_func_*`に書かれているので、アクションを剥がす前に「規則 → Itemクラス」として拾う。③結果型の種別はItemクラスの継承から取れる: 登録277クラスの直接の基底は`Item_int_func`（77、LONGLONG）・`Item_str_func`（53、文字列）・`Item_dec_func` / `Item_real_func`（21、DOUBLE）・`Item_json_func`（10）・`Item_bool_func`（8）・日時系（9）・空間系（33）で大半が決まる。④引数型・NULL可・正確な結果型は各クラスの`resolve_type`（257個）にあり、その多くが宣言的な呼び出し — `param_type_is_default(from, to, TYPE)`（97箇所、引数の既定型）、`set_data_type_string / longlong / double / decimal / datetime / date / time / json`、`set_nullable`（82）、`aggregate_type`（引数型の合成）— で書かれているので、本体を字句的に読んで表にできる。⑤宣言的でない残り（`unsigned_flag`の伝播、長さ計算、引数で結果型が変わるもの）と④の検算は、本物のmysqld（配布tarballを`--initialize`で起こす。embedded-postgresの役）に①②から生成した`SELECT f(?, ...)`をプリペアドステートメントで問い、結果メタデータで埋める。「何が存在し何個の引数を取るか」を手で列挙しないのが要点で、抽出した表が計測の入力になる。型規則（暗黙変換・数値の昇格・文字列と数値の比較）は`Item_func::aggregate_type`と`item_cmpfunc.cc`の比較種別決定（`get_cmp_type`相当）を読んで移し、mysqldとの差分テストで検算する From bdca02adee6124558159ea2b4e638d90c81f49e3 Mon Sep 17 00:00:00 2001 From: kr9ly Date: Wed, 9 Sep 2026 13:24:38 +0900 Subject: [PATCH 004/125] =?UTF-8?q?mysql/internal/parsegen:=20the=20spike'?= =?UTF-8?q?s=20shell,=20sed=20and=20TypeScript=20become=20one=20Go=20gener?= =?UTF-8?q?ator=20=E2=80=94=20strip=20the=20grammar,=20cut=20the=20lexer?= =?UTF-8?q?=20on=20signature=20anchors=20that=20fail=20loudly,=20split=20m?= =?UTF-8?q?ysql-test=20the=20way=20mysqltest=20reads=20it,=20and=20drive?= =?UTF-8?q?=20bison,=20gen=5Flex=5Fhash,=20uca9dump,=20g++=20and=20em++=20?= =?UTF-8?q?with=20the=20library=20objects=20cached;=20mysql/=20starts=20as?= =?UTF-8?q?=20the=20nested=20module=20with=20a=20go.work=20at=20the=20root?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Output was compared byte for byte with the spike's before the spike was removed.

We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS diff --git a/cmd/sqlshape/go.mod b/cmd/sqlshape/go.mod new file mode 100644 index 0000000..83fdfb1 --- /dev/null +++ b/cmd/sqlshape/go.mod @@ -0,0 +1,26 @@ +module github.com/kr9ly/sqlshape/cmd/sqlshape/v2 + +go 1.26.1 + +// The binary is its own module so that it can be GPLv2 (it will carry the MySQL parser) +// while the runtime and pgtest stay Apache 2.0 at their import paths.

You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS From e65cffd071317d5fc80948e54954ecfb068a5b31 Mon Sep 17 00:00:00 2001 From: kr9ly Date: Wed, 9 Sep 2026 13:37:01 +0900 Subject: [PATCH 006/125] =?UTF-8?q?mysql/internal/mysqlparse:=20the=20Go?= =?UTF-8?q?=20side=20of=20the=20MySQL=20parser=20=E2=80=94=20the=20wasm=20?= =?UTF-8?q?module=20exports=20a=20parse=20API=20whose=20result=20is=20the?= =?UTF-8?q?=20CST=20in=20a=206-byte-per-node=20preorder=20wire=20format,?= =?UTF-8?q?=20node=20kinds=20are=20the=20grammar's=20own=20rule=20and=20to?= =?UTF-8?q?ken=20names=20numbered=20once=20in=20parsegen=20and=20shared=20?= =?UTF-8?q?by=20the=20C++=20actions=20and=20kinds.go,=20and=20wazero=20run?= =?UTF-8?q?s=20it=20the=20way=20pgparse=20does;=20the=20mysql-test=20corpu?= =?UTF-8?q?s=20parses=20at=2099.89%=20through=20wasm=20in=20under=20four?= =?UTF-8?q?=20seconds?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Co-Authored-By: Claude Fable 5.1 --- mysql/internal/mysqlparse/kinds.go | 1730 +++++++++++++++++ mysql/internal/mysqlparse/mysqlparse.go | 353 ++++ mysql/internal/mysqlparse/mysqlparse_test.go | 156 ++ .../mysqlparse/wasm/mysqlparse_8.4.wasm | Bin 0 -> 4499876 bytes mysql/internal/parsegen/cc/cst.cc | 23 +- mysql/internal/parsegen/cc/cst.h | 14 +- mysql/internal/parsegen/cc/main.cc | 51 +- mysql/internal/parsegen/cc/parse.cc | 94 + mysql/internal/parsegen/cc/parse.h | 28 + .../internal/parsegen/cc/shim/sql/thd_shim.h | 6 +- mysql/internal/parsegen/cmd/parsegen/main.go | 3 +- mysql/internal/parsegen/grammar.go | 59 +- mysql/internal/parsegen/parsegen_test.go | 18 +- mysql/internal/parsegen/toolchain.go | 53 +- 14 files changed, 2526 insertions(+), 62 deletions(-) create mode 100644 mysql/internal/mysqlparse/kinds.go create mode 100644 mysql/internal/mysqlparse/mysqlparse.go create mode 100644 mysql/internal/mysqlparse/mysqlparse_test.go create mode 100644 mysql/internal/mysqlparse/wasm/mysqlparse_8.4.wasm create mode 100644 mysql/internal/parsegen/cc/parse.cc create mode 100644 mysql/internal/parsegen/cc/parse.h diff --git a/mysql/internal/mysqlparse/kinds.go b/mysql/internal/mysqlparse/kinds.go new file mode 100644 index 0000000..efd2545 --- /dev/null +++ b/mysql/internal/mysqlparse/kinds.go @@ -0,0 +1,1730 @@ +// Code generated by parsegen from MySQL 8.4.6 sql_yacc.yy.

ライセンスと構成（裁定 2026-09-09、改訂）: MySQLサーバはGPLv2で、Apache 2.0のsqlshapeと同じ成果物には混ぜられない（libpg_queryの形が成立したのはPostgreSQL Licenseが寛容だったから）。守るのは「利用者のランタイムにGPLが混入しない」の1点で、優先するのは利用者の使いやすさ。MySQLとPostgreSQLで別のバイナリを使い分けさせることはしない。そこでモノレポの中でモジュールを2種に分ける。① Apache 2.0のまま残るもの: 利用者のコードにリンクされる`sqlshape`（ランタイム）と`pgtest`、`pgtest`が使うPostgreSQL側の解析（`internal/analyze` / `schema` / `catalog` / `pgparse` / `oracle` / `verify`）、テンプレート展開、義務、vetのフロントエンド。import pathは`github.com/kr9ly/sqlshape`のまま動かさない。② GPLv2に置くもの: MySQLの文法・字句解析器・関数表を切り出したwasmとそのアナライザー（`github.com/kr9ly/sqlshape/mysql`、ネストしたモジュール）、そして両方を積む1つのバイナリ`cmd/sqlshape`（ネストしたモジュール、GPLv2。Apache→GPLの一方向importは互換）。バイナリは`schema.sql`の宣言（`-- sqlshape: postgres 18` / `-- sqlshape: mysql 8.4`）で方言を選び、vetとしてもマイグレーションとしても同じ1つで済む。利用者のアプリにリンクされるのは①だけなので、GPLは開発ツールに閉じる（gccと同じ）。`internal/`の参照はパスの接頭辞で判定されるのでネストしたモジュールからも通る見込みだが、これとネストしたモジュールのタグ付け（`cmd/sqlshape/vX.Y.Z`）と`go install`の解決はスパイクで確認する。退けた案: MySQL対応を別リポジトリ・別バイナリ`sqlshape-mysql`にする（当初の裁定。利用者にDBごとのバイナリを使い分けさせることになる）、パーサを別プロセスにしてパイプで木を渡す（FSFは密なデータ交換を結合とみなし得るとしていて灰色、構造も歪む）、Apache 2.0の互換パーサ（TiDB parser / Vitess）を使う（原則を捨てる）、抽出を事実に限定して文法を手書きする（一番品質が欲しい文法が手書きになる） - パーサと字句解析器（裁定 2026-09-09）: MySQLサーバのソースから機械的に切り出し、libpg_queryと同じ形でwasmにする。原則は「本物から機械的に抽出したものを土台にし、手で書く部分を最小にする」。文法は`sql/sql_yacc.yy`（bison、18k行、`%expect 59`）からC++のアクション（`NEW_PTN`が923箇所）を剥がして規則・優先順位・トークンだけを残し、規則名と子要素だけの素の構文木（CST）を組む汎用アクションを機械生成してbisonに通す。字句解析器は`sql/sql_lex.cc`の`lex_one_token`（726行）と2トークン先読みの`MYSQLlex`（`WITH ROLLUP`等の合成）、`Lex_input_stream`（440行）、`find_keyword`（`sql/lex.h`の784語の表から`gen_lex_hash`が生成する完全ハッシュ）、`consume_comment`・`int_token`をそのまま使う。測ったところ、字句解析器がサーバ状態を読むのは5点だけ — `sql_mode`（`ANSI_QUOTES`の1箇所）、`default_collation_for_utf8mb4`、接続文字集合、コメント収集の`m_parser_state`、非推奨文字集合の`push_warning`（2箇所）— なのでTHDはこの5点を持つ数十行のshimで置き換える。文字の分類（`state_map` / `ident_map`）は`strings/sql_chars.cc`が文字集合のctype表から作るもので、`strings/`ライブラリごと取り込む（PGの`src/port`をlibpg_queryが抱えるのと同じ）。バージョンコメント`/*!80000 ... */`は`MYSQL_VERSION_ID`との比較なので、版ごとにビルドすれば自然に正しい。sqlshape用のASTへの変換だけが手書きで、CSTの規則名を読む。生成手段はこの裁定でbison + emccに決まる（goyaccでpure Goに持つ案は字句解析器の書き直しを伴うので原則に反する）。残る確認はスパイク: shimの表面積が本当に5点で閉じるか、抽出した文法とlexerがemccで通るか、`mysql-test/t`（1810ファイル）の受理率 - スパイクの結果（2026-09-09、`mysql/spike/`）: 三点とも成立。shimの表面積は5点で閉じた（警告・digest・utf8本文・オプティマイザヒントは空実装）。アクションを剥がした文法はbison 3.8で`%expect 59`のまま通り、トークン番号は本物と一致する。`mysql-test/t`の1,455ファイルを文に割った137,062文のうち、エラーを期待しない125,187文の99.89%を受理し、残りはテストハーネス側の事情（delimiter、クライアント文字集合の切り替え、パーサ深さの試験）で文法の穴は見つかっていない。MySQLがアクション内で出す構文エラー（予約関数名のテーブル名、`<=>ALL`）はCSTパーサでは通るので、意味層で拾う + - CST→AST（裁定 2026-09-09）: 剥がしたアクションの中身が CST→AST の対応表なので、parsegenがそれを読み戻して`shapes.go`（規則×選択肢 → server が何を組んだか）を生成し、`mysqlast`が汎用に再生する。ノードは server の PT クラス（`PT_query_specification` / `PTI_where` / `Item_func_eq`）で、引数名はヘッダのコンストラクタから、by-value の struct のフィールド名は`parser_yystype.h`から取る。読めないアクション（到達範囲で約 45）は hook を手書きし、hook は規則名と右辺の記号列で結び、版が上がってずれれば init で落ちる。読めもせず hook も無い構文は`Unsupported`として明示する。mysql-test の DML/DDL の 97.7% が組める + - アナライザーが読む木（裁定 2026-09-09）: mysqlast を直接読む（PG 側が pg_query のノードを直接読むのと同じ位置づけ）。parsegen が持つコンストラクタ引数名から PT クラスごとの型付きビュー（`AsPTQuerySpecification(v)` と引数名のアクセサ）を生成して、アナライザーはそれを通す。MySQL 専用の正規化した文モデルは作らない。版ごとの揺れは hook と引数名の照合で露見させ、吸収層が要るかは SELECT の解析を書いてから判断する +- 方言の口（裁定 2026-09-09）: vet が`analyze.Result` / `schema.Schema` / `pgparse`に直接依存しているので、ルートに`internal/dialect`を切る。`Load(schemaSQL) (Analyzer, error)`、`Analyzer.Analyze(sql) (*Result, error)`、Go 型 ↔ SQL 型の対応表を方言が提供し、`schema.sql`の先頭宣言（`-- sqlshape: postgres 18` / `-- sqlshape: mysql 8.4`）で選ぶ。`Result`は方言非依存の形（型は名前と NULL 可否、出所はテーブル・列名、`facts.Facts`）に寄せる。PG 実装は`internal/analyze`の薄い adapter、MySQL 実装は`mysql/`側。vet が pgparse に触る 2 箇所（ORDER BY の hazard、束縛の定数）は方言側へ。SQLite 等の第三の方言もこの口に足すだけで済む形にする（パーサは同じ手法 — 本物の文法からの機械抽出 — で、Lemon の文法なら parsegen に相当する生成器をもう 1 つ書く） - 文字集合レジストリ（裁定 2026-09-09）: `strings/`の照合ライブラリを丸ごとリンクする（ctype-*.cc、collations*.cc、`uca9dump`が生成するzh/jaの重み表）。wasmは4.6MBで、名前だけの表なら0.9MBだが、手で持つ表をゼロにすることと、型層でPAD SPACE・mbmaxlen・既定照合を参照するときにレジストリがそのまま答えになることを優先した。サイズが問題になったら重み表（`uca900_data.h`とhan表、約3MB）だけを空にする - `sql_mode`は判定を変えるので、版と同じくschema.sqlが宣言する（`-- sqlshape: mysql 8.4 sql_mode=...`の形は未決）。字句では`ANSI_QUOTES`、文法のアクションを剥がすので`PIPES_AS_CONCAT`（`||`）の意味はCST→ASTの変換で`sql_mode`を見て決める - オプティマイザヒント（`/*+ ... */`）は別の文法`sql/sql_hints.yy`（725行）と`Hint_scanner`を持つ。同じ手順で後から足せる。sqlshapeの判定には効かないので初期は読み飛ばす From bed502050d04a38e2470beb89411cd237dd9fb37 Mon Sep 17 00:00:00 2001 From: kr9ly Date: Wed, 9 Sep 2026 14:25:44 +0900 Subject: [PATCH 012/125] =?UTF-8?q?mysqlast/views.go:=20parsegen=20generat?= =?UTF-8?q?es=20a=20typed=20view=20per=20parse-tree=20class=20=E2=80=94=20?= =?UTF-8?q?AsPTQuerySpecification(v).OptWhereClause()=20=E2=80=94=20from?= =?UTF-8?q?=20the=20constructor=20parameter=20names,=20so=20the=20analyzer?= =?UTF-8?q?=20reads=20the=20server's=20classes=20by=20name=20rather=20than?= =?UTF-8?q?=20by=20position;=20generated=20Go=20passes=20through=20go/form?= =?UTF-8?q?at?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Co-Authored-By: Claude Fable 5.1 --- mysql/internal/mysqlast/mysqlast_test.go | 26 + mysql/internal/mysqlast/views.go | 6705 ++++++++++++++++++ mysql/internal/parsegen/cmd/parsegen/main.go | 3 +- mysql/internal/parsegen/grammar.go | 101 + mysql/internal/parsegen/toolchain.go | 17 +- 5 files changed, 6850 insertions(+), 2 deletions(-) create mode 100644 mysql/internal/mysqlast/views.go diff --git a/mysql/internal/mysqlast/mysqlast_test.go b/mysql/internal/mysqlast/mysqlast_test.go index 5cf535c..3446063 100644 --- a/mysql/internal/mysqlast/mysqlast_test.go +++ b/mysql/internal/mysqlast/mysqlast_test.go @@ -197,3 +197,29 @@ func TestUnknownAlterAlgorithm(t *testing.T) { t.Errorf("want Unsupported for an unknown ALGORITHM, got %v", err) } } + +func TestViews(t *testing.T) { + sql := "SELECT a FROM t WHERE b = 1" + stmt, ok := AsPTSelectStmt(mustBuild(t, sql)) + if !ok { + t.Fatal("not a PT_select_stmt") + } + qe, ok := AsPTQueryExpression(stmt.Qe()) + if !ok { + t.Fatal("no query expression") + } + // `$1.body` in the server's action already picked the field of the by-value struct + spec, ok := AsPTQuerySpecification(qe.Body()) + if !ok { + t.Fatalf("no query specification in %s", Sprint(qe.Body())) + } + items, _ := spec.ItemList().(List) + where, ok := AsPTIWhere(spec.OptWhereClause()) + if len(items) != 1 || !ok { + t.Fatalf("items=%d where=%v (%s)", len(items), ok, Sprint(spec.OptWhereClause())) + } + cmp, ok := AsPTICompOp(where.Expr()) + if !ok || cmp.Boolfunc2creator() != Op("=") { + t.Errorf("comparison: %s", Sprint(where.Expr())) + } +} diff --git a/mysql/internal/mysqlast/views.go b/mysql/internal/mysqlast/views.go new file mode 100644 index 0000000..b5acdd0 --- /dev/null +++ b/mysql/internal/mysqlast/views.go @@ -0,0 +1,6705 @@ +// Code generated by parsegen from MySQL 8.4.6.

MySQLには`pg_proc`に当たる表がないが、組み込み関数の定義はソースにまとまっていて機械抽出できる。①関数表`sql/item_create.cc`の`func_array`（347エントリ）: 名前 → Itemクラス × 引数個数（固定 / 最小・最大 / 偶奇）。②キーワード構文の関数（`CAST`・`TRIM`・`DATE_ADD`等、81クラス）は`sql_yacc.yy`のアクションの`NEW_PTN Item_func_*`に書かれているので、アクションを剥がす前に「規則 → Itemクラス」として拾う。③結果型の種別はItemクラスの継承から取れる: 登録277クラスの直接の基底は`Item_int_func`（77、LONGLONG）・`Item_str_func`（53、文字列）・`Item_dec_func` / `Item_real_func`（21、DOUBLE）・`Item_json_func`（10）・`Item_bool_func`（8）・日時系（9）・空間系（33）で大半が決まる。④引数型・NULL可・正確な結果型は各クラスの`resolve_type`（257個）にあり、その多くが宣言的な呼び出し — `param_type_is_default(from, to, TYPE)`（97箇所、引数の既定型）、`set_data_type_string / longlong / double / decimal / datetime / date / time / json`、`set_nullable`（82）、`aggregate_type`（引数型の合成）—

...)`をプリペアドステートメントで問い、結果メタデータで埋める。「何が存在し何個の引数を取るか」を手で列挙しないのが要点で、抽出した表が計測の入力になる。型規則（暗黙変換・数値の昇格・文字列と数値の比較）は`Item_func::aggregate_type`と`item_cmpfunc.cc`の比較種別決定（`get_cmp_type`相当）を読んで移し、mysqldとの差分テストで検算する

可否・プレースホルダの型を補う。ヘッダにインラインで書かれた`resolve_type`（109 個）も parsegen が読むようにした（facts を持つクラス 144 → 323）。NULL 可否の既定は「引数のどれかが NULL 可なら NULL 可」（`Item_func::fix_fields`）、集約は「行が無ければ NULL」で COUNT / BIT_* /

を`--initialize`で起こす）はカタログ生成のときに手元でだけ使い、生成物をコミットする。CI は検算しない（PG の`catalog/gen`と同じ扱い。tarball は 500MB 級で CI に載せる価値がない）。tarball は`~/.cache/sqlshape/mysql-`に置く - 回帰コーパスはMySQL自身の`mysql-test/t/*.test`。パーサの受理率と、オラクルとの差分probeの両方に使う - 順序: パーサのスパイク（受理率で手段を裁定）→ 字句解析器 → CST→AST → スキーマローダー（CREATE TABLEの部分集合、`mysqldump`の正準形）→ アナライザーの型規則（mysqldをオラクルに差分テスト）→

2.x、多段の手順が要る）、root も`/v2`に上げて 2.x で揃える（ランタイム利用者の import path が変わる） - パーサと字句解析器（裁定 2026-09-09）: MySQLサーバのソースから機械的に切り出し、libpg_queryと同じ形でwasmにする。原則は「本物から機械的に抽出したものを土台にし、手で書く部分を最小にする」。文法は`sql/sql_yacc.yy`（bison、18k行、`%expect 59`）からC++のアクション（`NEW_PTN`が923箇所）を剥がして規則・優先順位・トークンだけを残し、規則名と子要素だけの素の構文木（CST）を組む汎用アクションを機械生成してbisonに通す。字句解析器は`sql/sql_lex.cc`の`lex_one_token`（726行）と2トークン先読みの`MYSQLlex`（`WITH ROLLUP`等の合成）、`Lex_input_stream`（440行）、`find_keyword`（`sql/lex.h`の784語の表から`gen_lex_hash`が生成する完全ハッシュ）、`consume_comment`・`int_token`をそのまま使う。測ったところ、字句解析器がサーバ状態を読むのは5点だけ — `sql_mode`（`ANSI_QUOTES`の1箇所）、`default_collation_for_utf8mb4`、接続文字集合、コメント収集の`m_parser_state`、非推奨文字集合の`push_warning`（2箇所）— なのでTHDはこの5点を持つ数十行のshimで置き換える。文字の分類（`state_map` / `ident_map`）は`strings/sql_chars.cc`が文字集合のctype表から作るもので、`strings/`ライブラリごと取り込む（PGの`src/port`をlibpg_queryが抱えるのと同じ）。バージョンコメント`/*!80000 ... */`は`MYSQL_VERSION_ID`との比較なので、版ごとにビルドすれば自然に正しい。sqlshape用のASTへの変換だけが手書きで、CSTの規則名を読む。生成手段はこの裁定でbison + emccに決まる（goyaccでpure Goに持つ案は字句解析器の書き直しを伴うので原則に反する）。残る確認はスパイク: shimの表面積が本当に5点で閉じるか、抽出した文法とlexerがemccで通るか、`mysql-test/t`（1810ファイル）の受理率 - スパイクの結果（2026-09-09、`mysql/spike/`）: 三点とも成立。shimの表面積は5点で閉じた（警告・digest・utf8本文・オプティマイザヒントは空実装）。アクションを剥がした文法はbison 3.8で`%expect 59`のまま通り、トークン番号は本物と一致する。`mysql-test/t`の1,455ファイルを文に割った137,062文のうち、エラーを期待しない125,187文の99.89%を受理し、残りはテストハーネス側の事情（delimiter、クライアント文字集合の切り替え、パーサ深さの試験）で文法の穴は見つかっていない。MySQLがアクション内で出す構文エラー（予約関数名のテーブル名、`<=>ALL`）はCSTパーサでは通るので、意味層で拾う - CST→AST（裁定 2026-09-09）: 剥がしたアクションの中身が CST→AST の対応表なので、parsegenがそれを読み戻して`shapes.go`（規則×選択肢 → server が何を組んだか）を生成し、`mysqlast`が汎用に再生する。ノードは server の PT クラス（`PT_query_specification` / `PTI_where` / `Item_func_eq`）で、引数名はヘッダのコンストラクタから、by-value の struct のフィールド名は`parser_yystype.h`から取る。読めないアクション（到達範囲で約 45）は hook を手書きし、hook は規則名と右辺の記号列で結び、版が上がってずれれば init で落ちる。読めもせず hook も無い構文は`Unsupported`として明示する。mysql-test の DML/DDL の 97.7% が組める - アナライザーが読む木（裁定 2026-09-09）: mysqlast を直接読む（PG 側が pg_query のノードを直接読むのと同じ位置づけ）。parsegen が持つコンストラクタ引数名から PT クラスごとの型付きビュー（`AsPTQuerySpecification(v)` と引数名のアクセサ）を生成して、アナライザーはそれを通す。MySQL 専用の正規化した文モデルは作らない。版ごとの揺れは hook と引数名の照合で露見させ、吸収層が要るかは SELECT の解析を書いてから判断する -- 方言の口（裁定 2026-09-09）: vet が`analyze.Result` /

機能は方言の事実として現れるだけで、共通化しない。契約（`One`の証明・義務・失敗モード）は事実（`facts.Facts`: どの列を読む・固定する・書く、どのキーで一意になる、どの制約に当たり得るか）の上に書く。契約が必要とする事実をその方言が生産できないなら、その契約はその方言ではエラーにする（黙って通さない）。これで「PG にある機能を MySQL でどう真似るか」は問いとして消え、「この契約が要る事実は何か、その方言はそれを出せるか」に置き換わる。3 層で見る: ① SQL の意味論（文法・型・エラー・名前解決）は各 server がそのまま正で、oracle で検算する ② sqlshape の契約は事実の上 ③ Go の受け型と実行時はドライバごとの表。含意: `dialect.Result`に Facts を載せて obligation を方言非依存にするのが次の設計課題。方言にだけある機能と契約の交差（`INSERT IGNORE`は失敗モードを飲み込む、`ON DUPLICATE KEY UPDATE`は`ON CONFLICT`相当、`RETURNING`が無いので「書いた値を読む」規則が成立しない）は個別に裁定する。**ドキュメント**: 何を約束し何を約束しないかが方言ごとに変わるので、利用者向け

Date: Thu, 10 Sep 2026 16:30:48 +0900 Subject: [PATCH 034/125] 2.0: every module path carries the /v2 major-version suffix Go requires of a 2.x module (github.com/kr9ly/sqlshape/v2, postgres/v2, pgtest/v2, check/postgres/v2, check/mysql/v2, cmd/sqlshape/v2); the shared checker parts leave internal/ for x/ (expand, dialect, facts), since the internal rule stops at a module's major-version

パーサと字句解析器（裁定 2026-09-09）: MySQLサーバのソースから機械的に切り出し、libpg_queryと同じ形でwasmにする。原則は「本物から機械的に抽出したものを土台にし、手で書く部分を最小にする」。文法は`sql/sql_yacc.yy`（bison、18k行、`%expect 59`）からC++のアクション（`NEW_PTN`が923箇所）を剥がして規則・優先順位・トークンだけを残し、規則名と子要素だけの素の構文木（CST）を組む汎用アクションを機械生成してbisonに通す。字句解析器は`sql/sql_lex.cc`の`lex_one_token`（726行）と2トークン先読みの`MYSQLlex`（`WITH ROLLUP`等の合成）、`Lex_input_stream`（440行）、`find_keyword`（`sql/lex.h`の784語の表から`gen_lex_hash`が生成する完全ハッシュ）、`consume_comment`・`int_token`をそのまま使う。測ったところ、字句解析器がサーバ状態を読むのは5点だけ — `sql_mode`（`ANSI_QUOTES`の1箇所）、`default_collation_for_utf8mb4`、接続文字集合、コメント収集の`m_parser_state`、非推奨文字集合の`push_warning`（2箇所）— なのでTHDはこの5点を持つ数十行のshimで置き換える。文字の分類（`state_map` / `ident_map`）は`strings/sql_chars.cc`が文字集合のctype表から作るもので、`strings/`ライブラリごと取り込む（PGの`src/port`をlibpg_queryが抱えるのと同じ）。バージョンコメント`/*!80000 ... */`は`MYSQL_VERSION_ID`との比較なので、版ごとにビルドすれば自然に正しい。sqlshape用のASTへの変換だけが手書きで、CSTの規則名を読む。生成手段はこの裁定でbison + emccに決まる（goyaccでpure Goに持つ案は字句解析器の書き直しを伴うので原則に反する）。残る確認はスパイク: shimの表面積が本当に5点で閉じるか、抽出した文法とlexerがemccで通るか、`mysql-test/t`（1810ファイル）の受理率 - スパイクの結果（2026-09-09、`mysql/spike/`）: 三点とも成立。shimの表面積は5点で閉じた（警告・digest・utf8本文・オプティマイザヒントは空実装）。アクションを剥がした文法はbison 3.8で`%expect 59`のまま通り、トークン番号は本物と一致する。`mysql-test/t`の1,455ファイルを文に割った137,062文のうち、エラーを期待しない125,187文の99.89%を受理し、残りはテストハーネス側の事情（delimiter、クライアント文字集合の切り替え、パーサ深さの試験）で文法の穴は見つかっていない。MySQLがアクション内で出す構文エラー（予約関数名のテーブル名、`<=>ALL`）はCSTパーサでは通るので、意味層で拾う - CST→AST（裁定 2026-09-09）: 剥がしたアクションの中身が CST→AST の対応表なので、parsegenがそれを読み戻して`shapes.go`（規則×選択肢 → server が何を組んだか）を生成し、`mysqlast`が汎用に再生する。ノードは server の PT クラス（`PT_query_specification` / `PTI_where` / `Item_func_eq`）で、引数名はヘッダのコンストラクタから、by-value の struct のフィールド名は`parser_yystype.h`から取る。読めないアクション（到達範囲で約 45）は hook を手書きし、hook は規則名と右辺の記号列で結び、版が上がってずれれば init で落ちる。読めもせず hook も無い構文は`Unsupported`として明示する。mysql-test の DML/DDL の 97.7% が組める - アナライザーが読む木（裁定 2026-09-09）: mysqlast を直接読む（PG 側が pg_query のノードを直接読むのと同じ位置づけ）。parsegen が持つコンストラクタ引数名から PT クラスごとの型付きビュー（`AsPTQuerySpecification(v)` と引数名のアクセサ）を生成して、アナライザーはそれを通す。MySQL 専用の正規化した文モデルは作らない。版ごとの揺れは hook と引数名の照合で露見させ、吸収層が要るかは SELECT の解析を書いてから判断する -- 方言の口（裁定 2026-09-09）: vet が`analyze.Result` / `schema.Schema` / `pgparse`に直接依存しているので、ルートに`internal/dialect`を切る。`Load(schemaSQL) (Analyzer, error)`、`Analyzer.Analyze(sql) (*Result, error)`、Go 型 ↔ SQL 型の対応表を方言が提供し、`schema.sql`の先頭宣言（`-- sqlshape: postgres 18` / `-- sqlshape: mysql 8.4`）で選ぶ。`Result`は方言非依存の形（型は名前と NULL 可否、出所はテーブル・列名、`facts.Facts`）に寄せる。PG 実装は`check/postgres/analyze`の薄い adapter、MySQL 実装は`mysql/`側。vet が pgparse に触る 2 箇所（ORDER BY の hazard、束縛の定数）は方言側へ。SQLite 等の第三の方言もこの口に足すだけで済む形にする（パーサは同じ手法 — 本物の文法からの機械抽出 — で、Lemon の文法なら parsegen に相当する生成器をもう 1 つ書く） +- 方言の口（裁定 2026-09-09）: vet が`analyze.Result` / `schema.Schema` / `pgparse`に直接依存しているので、ルートに`x/dialect`を切る。`Load(schemaSQL) (Analyzer, error)`、`Analyzer.Analyze(sql) (*Result, error)`、Go 型 ↔ SQL 型の対応表を方言が提供し、`schema.sql`の先頭宣言（`-- sqlshape: postgres 18` / `-- sqlshape: mysql 8.4`）で選ぶ。`Result`は方言非依存の形（型は名前と NULL 可否、出所はテーブル・列名、`facts.Facts`）に寄せる。PG 実装は`check/postgres/analyze`の薄い adapter、MySQL 実装は`mysql/`側。vet が pgparse に触る 2 箇所（ORDER BY の hazard、束縛の定数）は方言側へ。SQLite 等の第三の方言もこの口に足すだけで済む形にする（パーサは同じ手法 — 本物の文法からの機械抽出 — で、Lemon の文法なら parsegen に相当する生成器をもう 1 つ書く） - 方言間の線引き（裁定 2026-09-10）: 機能は方言の事実として現れるだけで、共通化しない。契約（`One`の証明・義務・失敗モード）は事実（`facts.Facts`: どの列を読む・固定する・書く、どのキーで一意になる、どの制約に当たり得るか）の上に書く。契約が必要とする事実をその方言が生産できないなら、その契約はその方言ではエラーにする（黙って通さない）。これで「PG にある機能を MySQL でどう真似るか」は問いとして消え、「この契約が要る事実は何か、その方言はそれを出せるか」に置き換わる。3 層で見る: ① SQL の意味論（文法・型・エラー・名前解決）は各 server がそのまま正で、oracle で検算する ② sqlshape の契約は事実の上 ③ Go の受け型と実行時はドライバごとの表。含意: `dialect.Result`に Facts を載せて obligation を方言非依存にするのが次の設計課題。方言にだけある機能と契約の交差（`INSERT IGNORE`は失敗モードを飲み込む、`ON DUPLICATE KEY UPDATE`は`ON CONFLICT`相当、`RETURNING`が無いので「書いた値を読む」規則が成立しない）は個別に裁定する。**ドキュメント**: 何を約束し何を約束しないかが方言ごとに変わるので、利用者向け docs は方言別の約束の表として整理し直す。実装より難しいと見ていて、契約の結線を MySQL に通すタイミングで再度整理する -

With them: a column outside an aggregate in HAVING must be a select-list column or alias or a GROUP BY column (1054, for a nested query's reference too), DISTINCT's ORDER BY may read only select-list columns (3065), an aggregate in the ORDER BY of a non-aggregated query (3029) or a set operation (3028). The 376 statements of fullgroup_test.go are a running mysqld's verdicts, kept so by TestFullGroupOracle. The facts producer records what the checks need -- Column.leaf1 / leafCol and the derived leaves' Outputs (so One now looks into a derived table's or view's body), (a, b) = (c, d) decomposed, null-rejecting conjunct marks per join side, the constness of an equality's known side, outer references with the block they resolve in, and a nested query's name may be an enclosing HAVING's select alias. The vet testdata's aggregated statement gains the WHERE the server requires; CHANGELOG updated Co-Authored-By: Claude Fable 5.1 --- CHANGELOG.md | 17 + check/mysql/internal/analyze/analyze.go | 79 +- check/mysql/internal/analyze/analyze_test.go | 4 +- check/mysql/internal/analyze/facts.go | 151 ++- check/mysql/internal/analyze/fullgroup.go | 1154 +++++++++++++++++ .../mysql/internal/analyze/fullgroup_test.go | 462 +++++++ check/mysql/internal/analyze/query.go | 28 +- cmd/sqlshape/testdata/mysql/src/app/app.go | 7 +- 8 files changed, 1871 insertions(+), 31 deletions(-) create mode 100644 check/mysql/internal/analyze/fullgroup.go create mode 100644 check/mysql/internal/analyze/fullgroup_test.go diff --git a/CHANGELOG.md b/CHANGELOG.md index 86d4659..149b403 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -69,6 +69,23 @@ release it is a candidate for.

From a2875e5886b2113b0e972d7ece55f460586db8d4 Mon Sep 17 00:00:00 2001 From: kr9ly Date: Fri, 11 Sep 2026 00:49:15 +0900 Subject: [PATCH 053/125] MySQL after an adversarial round against a running mysqld (7 lanes, 21 findings, each a regression test in adv_*_test.go): a USING / NATURAL join coalesces its common columns (an unqualified name resolves to the left side, SELECT * lists it once); GROUP BY on an aggregate's alias is 1056; multi-table DELETE (targets listed before FROM or after USING) is analyzed with every target judged for the failure modes; the select list is resolved before the WHERE; a BIT operand is unsigned in arithmetic; WITH ROLLUP makes the non-aggregated result columns nullable; STR_TO_DATE follows a literal format (fix_from_format) into DATE / TIME / DATETIME; `->` and `->>` are JSON_EXTRACT / JSON_UNQUOTE(JSON_EXTRACT) (mysqlast hooks). The facts do not take an execution-bound expression (RAND()) for a known term, so GROUP BY RAND() is not single and `tenant_id = FLOOR(RAND() * 3)` pins nothing; a parameter stays deterministic. Failure modes: REPLACE violates no key and may violate a referencing foreign key (1451), a multi-table UPDATE judges each table's own assignments (write.more), an UPDATE through an updatable view judges and sources its base table. The schema loader names unnamed CHECK / FOREIGN KEY constraints as the server does (one above the highest generated number, so a DROP by generated name matches and a later ADD does not reuse the number) and reads table and view names case-sensitively. mysql.ExecOne accepts the 0 / 1 / 2 rows INSERT ... ON DUPLICATE KEY UPDATE and REPLACE report for the one row their key names.

The One proof sees through a cast on the grouped column, takes a one-element = ANY(ARRAY[v]) and a NOT NULL column's IS NOT DISTINCT FROM v, and matches a partial index's predicate with the literal casts a statement spells; col = NULL fixes nothing on either dialect (MySQL keeps it for ONLY_FULL_GROUP_BY's dependencies, as the server does). SET col = DEFAULT is the column's literal default (transitions judge it as a state). -strict rejects []T for an array whose element cannot be NULL and both modes note it; interval into time.Duration is Lossy. vet follows a Query[R, P] called through a package-level variable and checks the fields an {{if}} reads through a nested call. migrate drops and restores what a generated column's rewrite (expression or STORED / VIRTUAL kind) takes with it. An unfiltered / waive above a CREATE TABLE is told where it belongs. Kept and documented: paired requires the write, not matching values; RETURNING a sensitive column is reading it.

The +dependencies the server recognizes are the ones the checker recognizes: a table's columns once +its `PRIMARY` or `UNIQUE` key is known (a nullable key column only where a conjunct rejects its +NULL), `col = col` and `col = literal` in `WHERE` and inner joins, an outer join's `ON` into its +nullable side, and a derived table's or view's body through its outputs; `ROLLUP` allows the group +expressions only. A column named outside an aggregate in `HAVING` must be a select-list column or +alias or a `GROUP BY` column (1054); with `DISTINCT` an `ORDER BY` expression not in the select +list may read only select-list columns (3065); an aggregate in the `ORDER BY` of a query that +aggregates nowhere else (3029) or of a set operation (3028) is rejected. + +```sql +SELECT email, count(*) FROM users GROUP BY name +-- Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column +-- 'users.email' which is not functionally dependent on columns in GROUP BY clause; this is +-- incompatible with sql_mode=only_full_group_by (MySQL error 1055) + +SELECT name, count(*) FROM users GROUP BY id -- OK: id is the primary key +``` + +### Name resolution + +`ORDER BY`, `GROUP BY` and `HAVING` see the select list's aliases as the server does (a table +column of the same name wins in `GROUP BY`); a derived table needs an alias (1248); `QUALIFY` is +rejected as 8.4 rejects it without the hypergraph optimizer (6037).

FROM`: + + ```go + var loadItems = postgres.Copy[Item]("order_items", "order_id", "line_no", "sku", "qty") + + n, err := loadItems.From(ctx, db, items) // []Item + n, err := loadItems.FromSeq(ctx, db, seq) // iter.Seq[Item] + ``` + + 各列には`R`のうちその列に対応するフィールドが入る。列を指定しなければ全フィールドが自分の名前の列に入り、スカラーの`R`は1列に入る。検査器はテーブル、列、各列の型とフィールドの型、指定しなかった列に既定値があることを確かめる（[checks.ja.md](checks.ja.md#copyで一括ロードするpostgresql)）。 +- `MatView`はマテリアライズドビューを名指す。`Refresh`と`RefreshConcurrently`（後者はビューに一意インデックスが要る。`-strict`が確かめる）。 + + ```go + var OrderStats = postgres.MatView("order_stats") + + err := OrderStats.Refresh(ctx, db) + err := OrderStats.RefreshConcurrently(ctx, db) + ``` + +## マイグレーション + +`sqlshape diff`、`apply`、`verify-schema`は、データベースと`schema.sql`の差分からDDLを導き、そのDDLが本当に`schema.sql`に至ることを確かめてから実行する。両側を`pg_dump`の出力として比較するので、宣言したバージョンの`pg_dump`が`PATH`に要り、`schema.sql`を読むために宣言したバージョンの埋め込みPostgreSQL（初回にダウンロードされ、`~/.cache/sqlshape`にキャッシュされる）を起動する。[migrations.ja.md](migrations.ja.md)は全部PostgreSQLのものである。 + +## License + +The PostgreSQL side of the checker (`check/postgres`) embeds `pg_catalog` data and validation +rules ported from PostgreSQL under the PostgreSQL License, see +[check/postgres/NOTICE](../check/postgres/NOTICE).

PostgreSQL never guarantees an array's elements are themselves not null -- a column's own `NOT NULL` only forbids the array value as a whole from being `NULL` -- so a result element type that cannot itself carry `NULL` (not already a pointer) carries a standing note, and `-strict` additionally reports it as rejected: `[]int32` for `integer[]` and `[]Item` for a composite array both need `[]*int32` / `[]*Item` to receive a `NULL` element safely (a composite element is worse: pgx silently decodes a `NULL` one as a zero-valued struct instead of erroring) | +| ranges | `pgtype.Range[T]`, with `T` checked against the subtype (user-defined ranges too) | +| multiranges | `pgtype.Multirange[pgtype.Range[T]]` | +| `bit` / `point` / `tsvector` | the `pgtype` value | +| `xml` / `money` / `tsquery` / `jsonpath` / `timetz` | `string` | +| `oid` | `uint32` | +| enums, seeded lookup keys, CHECK value sets | a Go named string type ([Giving types a meaning](checks.md#giving-types-a-meaning)) | +| domains | the base type's Go type, or a named type bound to the domain | +| composites, records | a struct | + +A type not in the table, or one you want to receive with your own type, is declared on the Go type +in its doc comment: + +```go +// sqlshape: type money_amount +type Money struct{ ... } // implements sql.Scanner / driver.Valuer +``` + +The checker then accepts `Money` exactly where the SQL has `money_amount` (its arrays and domains +over it included) and reports it anywhere else.

What pgx adds: + +- `Stmt.Unprepared()` returns a copy that runs without a server-side prepared statement, so the + planner makes a custom plan for the actual values every time. Use it for statements whose + parameters have skewed distributions, where pgx's statement cache would settle on a generic + plan. Otherwise prepared-statement caching is pgx's, per expansion. +- Nested rows and user types. `array_agg(row(o.id, o.total))`, `array_agg(o)`, `row(...)` and + composite-typed columns are scanned into a struct or a slice of structs field by field, + positionally for an anonymous record and by the composite's column order for a named one. + Composite parameters are encoded from a struct or a slice of structs the same way. pgx has to + know a user-defined type (enum, composite, domain, range, multirange, and their arrays) before + it can decode it: `Run` loads the types a result needs on the connection the first time it + meets them; types nested inside an anonymous record cannot be seen before scanning, so for + those, and for pools, register everything once: + + ```go + cfg.AfterConnect = func(ctx context.Context, conn *pgx.Conn) error { + return postgres.LoadUserTypes(ctx, conn) + } + ``` + + Extension scalar types pgx's own loader does not read (`citext`, `hstore`, `ltree`, ...) are + registered too: `hstore` with pgx's hstore codec (`map[string]*string`), the others as text. + A type with a declared binding (`// sqlshape: type money_amount`) is left to its own + `sql.Scanner` / `driver.Valuer`; the runtime asks PostgreSQL for the text format on those + columns and remembers the request per statement. If the type was dropped and recreated since + (a migration, same name, new OID), the runtime notices PostgreSQL's "cached plan must not + change result type" and re-derives the request once. +- Errors. A constraint violation (SQLSTATE class 23) comes back as a `*postgres.ConstraintError` + with the `Code`, `Constraint`, `Table`, `Column` and `Detail` PostgreSQL reported, wrapping the + `*pgconn.PgError`. `Key()` is the violation as the expect line spells it; a `NOT NULL` a domain + raises is the one case PostgreSQL reports with no table or column, so `Key()` is the domain's + name there. `postgres.Violates(err, key)` tests for it. `postgres.ErrNoRows` is `pgx.ErrNoRows`. +- `Batch` sends several statements in one round trip (`pgx.Batch`): + + ```go + b := postgres.NewBatch() + orders := postgres.Queue(b, ListOrders, ListParams{Status: &paid}) + paid := postgres.QueueOne(b, MarkPaid, struct{ ID int64 }{id}) + if err := b.Send(ctx, db); err != nil { ... } + rows, err := orders.Rows() // []Order; First() for the first row + tag, err := paid.Tag() + ``` + + A `BatchDB` is anything with `SendBatch`: connection, pool or transaction. Types cannot be + loaded mid-batch, so with user enums or composites in play call `LoadUserTypes` first. A + statement whose rows carry a `sql.Scanner` type cannot ride in a pgx batch, which never asks + for text format; `Send` runs it as a plain query right after the batch, in queue order. A + queued statement's violations are mapped to `*ConstraintError` the same way `Run` maps them; + `Send` returns the first, and the statements after it were not executed (`ErrNotSent`). +- `Copy` is `COPY ... FROM` through `pgx.CopyFrom`: + + ```go + var loadItems = postgres.Copy[Item]("order_items", "order_id", "line_no", "sku", "qty") + + n, err := loadItems.From(ctx, db, items) // []Item + n, err := loadItems.FromSeq(ctx, db, seq) // iter.Seq[Item] + ``` + + Each column is fed by the field of `R` that binds to it; with no columns given every field feeds + the column of its name; a scalar `R` feeds one column. The checker verifies the table, the + columns, each column's type against its field, and that every column left out has a default + ([checks.md](checks.md#bulk-loading-with-copy-postgresql)). +- `MatView` names a materialized view: `Refresh` and `RefreshConcurrently` (the latter needs a + unique index on the view, which `-strict` verifies). + + ```go + var OrderStats = postgres.MatView("order_stats") + + err := OrderStats.Refresh(ctx, db) + err := OrderStats.RefreshConcurrently(ctx, db) + ``` + +## Migrations + +`sqlshape diff`, `apply` and `verify-schema` derive the DDL from the difference between a +database and `schema.sql`, check that the DDL leads to `schema.sql`, and run it.

AFTER), keys, foreign keys, checks and views. check/mysql/migrate plans drops (referencing foreign keys first, then views, tables, parts), the declared renames, alterations from the target's own definition texts, additions in foreign-key order, the column order, the backfills; Verify applies the DDL on the canonical current text and compares; Split cuts a script for apply, which runs statement by statement (MySQL's DDL commits implicitly) and reports the statement that failed. -- @migrate keeps its grammar; enum names the ENUM column and updates rows before the type narrows. The loader keeps each column's, key's, foreign key's and check's definition text. The consumer index and the impacts are dialect-neutral. The analyzer no longer swallows an error in an INSERT's or UPDATE's value expression (SET total = nope is 1054, as on the server). Verified against mysqld: the 5-mysql example's seven edits there and back, six declaration problems, the cli round trip. docs (migrations both languages with a MySQL section and requirements, mysql.md / postgres.md / README), CHANGELOG, design.md Co-Authored-By: Claude Fable 5.1 --- CHANGELOG.md | 10 + README.ja.md | 16 +- README.md | 21 +- check/mysql/diff/diff.go | 344 ++++++++++ check/mysql/dump/dump.go | 371 +++++++++++ check/mysql/dump/dump_test.go | 105 +++ check/mysql/internal/analyze/analyze.go | 32 +- check/mysql/internal/schema/schema.go | 22 +- check/mysql/migrate/intents.go | 243 +++++++ check/mysql/migrate/migrate.go | 703 ++++++++++++++++++++ check/mysql/migrate/migrate_test.go | 230 +++++++ cmd/sqlshape/internal/cli/apply.go | 9 +- cmd/sqlshape/internal/cli/cli.go | 31 +- cmd/sqlshape/internal/cli/cli_extra_test.go | 14 +- cmd/sqlshape/internal/cli/consumers.go | 97 ++- cmd/sqlshape/internal/cli/diff.go | 9 +- cmd/sqlshape/internal/cli/mysql.go | 218 ++++++ cmd/sqlshape/internal/cli/mysql_test.go | 92 +++ cmd/sqlshape/internal/cli/verify.go | 5 + docs/checks.ja.md | 2 +- docs/checks.md | 2 +- docs/design.md | 1 + docs/migrations.ja.md | 26 +- docs/migrations.md | 52 +- docs/mysql.ja.md | 8 +- docs/mysql.md | 14 +- docs/postgres.ja.md | 4 +- docs/postgres.md | 8 +- docs/templates.ja.md | 2 +- docs/templates.md | 2 +- 30 files changed, 2600 insertions(+), 93 deletions(-) create mode 100644 check/mysql/diff/diff.go create mode 100644 check/mysql/dump/dump.go create mode 100644 check/mysql/dump/dump_test.go create mode 100644 check/mysql/migrate/intents.go create mode 100644 check/mysql/migrate/migrate.go create mode 100644 check/mysql/migrate/migrate_test.go create mode 100644 cmd/sqlshape/internal/cli/mysql.go create mode 100644 cmd/sqlshape/internal/cli/mysql_test.go diff --git a/CHANGELOG.md b/CHANGELOG.md index 3894de7..c8dd4c5 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -57,6 +57,16 @@ release it is a candidate for. ### Added +- `sqlshape diff`, `apply` and `verify-schema` work on a MySQL schema.

AnalyzeTrigger / AnalyzeRoutine walk blocks, DECLARE (variables, conditions, handlers, cursors), IF / CASE / LOOP / WHILE / REPEAT, labels with LEAVE / ITERATE, RETURN, SET (a local variable, NEW.col, a user variable; a system variable is skipped), SIGNAL / RESIGNAL, CALL, OPEN / FETCH / CLOSE, SELECT ... INTO and the embedded INSERT / UPDATE / DELETE, whose facts the dialect reports as definitions ("trigger x: line N") for the schema's obligations. A declared variable or parameter shadows a column of its name, as on the server; NEW.col / OLD.col are the trigger table's columns (a NOT NULL column's NEW.col may still be NULL in a BEFORE trigger, measured). The server's own CREATE-time refusals, measured on 8.4: 1054 unknown NEW / OLD column, 1362 / 1363 wrong row for the event or timing, 1308 / 1313 / 1320 / 1322 / 1324 / 1327 / 1328 / 1222, 1415 a result set from a trigger or function, 1422 a commit inside one.

A statement on a table takes the SIGNALs of the table's triggers for its event (INSERT / UPDATE / DELETE; REPLACE fires the INSERT and DELETE triggers, ON DUPLICATE KEY UPDATE the INSERT and UPDATE ones, measured), the constraints the trigger's own writes may violate, and what those writes fire in turn (a cycle is cut). A SIGNAL's key is its MYSQL_ERRNO in decimal when it sets one, else its SQLSTATE; class 01 is a warning and no failure mode, an unhandled class 02 is 1643, any other 1644; a named CONDITION resolves to its value. A DECLARE ... HANDLER FOR absorbs the matching failure modes of its block (SQLEXCEPTION everything but the 01 and 02 classes, SQLWARNING / NOT FOUND their class, a SQLSTATE or number itself); a bare RESIGNAL in the handler gives them back. INSERT / UPDATE IGNORE absorbs no trigger's SIGNAL (measured). SELECT ... INTO carries 1172 unless the query is provably at most one row (x/cardinality). A trigger writing its own table is 1442 on every one of the 18 timing x event x write combinations (measured), reported on the definition. Bodies analyze once per schema (cached) and keep their absorbed failure modes on BodyResult.Violations for the routine call sites to come. Cross-checked against mysqld.

A function the catalog does not know resolves to the schema's (an unqualified name that is also a native function is the native one, as on the server; db.f names the routine), types as its RETURNS, types a `?` argument by the parameter, takes 1318 for a wrong argument count and 1305 for no such routine, and brings the body's failure modes (SIGNALs, the body's own writes' violations, what they fire) to the calling statement; a function that writes a table the statement references is 1442 on every run (measured: reading the table is enough). CALL p(...) analyzes: IN / INOUT arguments by the parameters, an OUT argument must be a variable (1414; a `?` is one), facts Kind Call, the result columns from the body's result-set SELECTs when they agree (none: no columns; several of different shapes: the checker's own error), the body's failure modes. Cross-checked against mysqld. examples/5-mysql calls its function.

Where the docs' wording drifted from the checker the test skips with the drift named, for the docs to catch up.

Two bugs the sweep found: a HANDLER FOR SQLWARNING / NOT FOUND / SQLEXCEPTION caught nothing (the condition constant was not read), and a routine's own 1172 was described with a blank trigger name; a dead 1442 description removed (a trigger writing its own table is an error of the definition, never a violation).

No fence or heading moved, the docs harness is unchanged and green.

The AST gained hooks for the schedule (AT / EVERY ... STARTS ... ENDS), ON COMPLETION, the status and COMMENT (SHOW CREATE EVENT's own text could not even be built before); the loader keeps an Event (schedule, bounds, options, body) and applies DROP EVENT, with ALTER EVENT a problem (write the final CREATE EVENT). AnalyzeEvent walks the body like a routine's -- a table the schema does not have is 1146 here where the server accepts it at CREATE time and fails at every run (measured), RETURN is 1313 (measured) -- and dialect.Definitions judges its statements for the obligations. dump reads events back through SHOW CREATE EVENT (last; DEFINER dropped), diff compares schedule, STARTS / ENDS / AT, completion, status, comment and body, migrate plans a changed or gone event as DROP EVENT + CREATE EVENT (DROP with the triggers', CREATE last). A time schema.sql leaves to the server -- an omitted STARTS, a STARTS or AT written as an expression -- is filled in at creation and read back as the literal creation time (measured), so dump marks it unfixed from the source text and diff leaves it out on both sides; a literal time is compared as written.

Bodies: dynamic SQL in a trigger or FUNCTION is the server's CREATE-time 1336 and a duplicate DECLARE 1331, both schema problems; a bare RESIGNAL's own SET MYSQL_ERRNO overrides the number and one outside any HANDLER is 1645; a CASE with no ELSE carries 1339; a routine CALLing itself is 1456; a FUNCTION or TRIGGER CALLing a result-set PROCEDURE is 1415; 1442 covers the whole trigger chain and a called routine's write reached through a fired trigger. Calls: NEW.col is a valid OUT argument in a BEFORE trigger; a stored FUNCTION in a generated column, DEFAULT (expr) or CHECK is refused at CREATE TABLE (3763 / 3770 / 3814); nested CALL result sets propagate. Failure modes: a multi-column UNIQUE with any column left NULL is exempt from 1062; an omitted NOT NULL column without DEFAULT is 1364; a CHECK on a generated column is judged against its source columns; STRICT_TRANS_TABLES binds only transactional engines (x/sqlmode tells the two strict flags apart); mysql.Violates reads 1442 / 1172 back. Types: NTH_VALUE is read, LAG / LEAD / FIRST_VALUE / LAST_VALUE typed; a BEFORE INSERT trigger's NEW.col of an AUTO_INCREMENT column is not nullable (a defaulted one is: an explicit NULL reaches the body, measured -- the smoke test over examples/5-mysql caught the broader first cut). Facts: ON DUPLICATE KEY UPDATE records its update branch and REPLACE a delete; a string column compared to a numeric literal fixes nothing; a HAVING conjunct over GROUP BY columns is a fact (kept out of the ONLY_FULL_GROUP_BY dependency closure, which TestFullGroup caught); a one-element IN is an equality on both dialects. Migrations: ADD / DROP COLUMN follow generated-column dependencies, a parent key and its referencing column widened together drop and re-add the foreign key around the two MODIFYs, a primary key moving off an AUTO_INCREMENT column drops and adds in one ALTER TABLE, a renamed primary-key column is a RENAME COLUMN, a new table's AUTO_INCREMENT=n reaches its CREATE TABLE. mysqltest.Start errors when the server's lower_case_table_names differs from the declaration. A write through a view declared WITH CHECK OPTION discharges require pinned (path ByView) when the view chain's WHERE fixes the column: x/facts.LiftThroughView shared by both producers, x/obligation's pinned reads FromView like FromPolicy; MySQL models 1369 as a failure mode (absorbed by UPDATE IGNORE, measured) and a write's target leaf through an updatable view now names the base table, so base-table obligations are checked for such writes at all. Docs (en / ja) for every changed promise, the new material as tables and bullets; CHANGELOG [2.0.0]; NOTES.

カタログの検算（裁定 2026-09-09）: mysqld オラクル（配布 tarball を`--initialize`で起こす）はカタログ生成のときに手元でだけ使い、生成物をコミットする。CI は検算しない（PG の`catalog/gen`と同じ扱い。tarball は 500MB 級で CI に載せる価値がない）。tarball は`~/.cache/sqlshape/mysql-`に置く + - マイグレーションの差分テスト（2026-09-15、実施）: `check/mysql/migrate`の`TestMigrateProbe`が、計画器の語彙（列型 12 種、生成列、キー、FK、AUTO_INCREMENT、CHECK、ビュー、トリガ、関数）からスキーマ A を乱数で生成し、変異（列の追加・削除・改名・拡幅・移動・NULL 可否、キー / FK / CHECK の付け外し、PK の既存列・新列への移動、表の追加・削除・改名、ENUM ラベル、ビュー・トリガ・関数の追加・削除・変更、生成式の変更）を 1〜3 個重ねて B を作り、`sqlshape apply`と同じ判定を実サーバで下す: Plan(A→B) の DDL を A を持つ mysqld に流して B の正準形と diff が空、その状態から再 Plan が空。変異は宣言（`-- @migrate`）も書く（左は今の名前、右はこれからの名前。1 オブジェクト 1 宣言になるよう、動かした対象は他の変異が触らない）。落ちた組は変異を削って最小化し、レポートに出す。seed 1 の 200 組がゲート。初回スイープ 11 seed 約 3,000 組で 7 クラスの順序問題を見つけて修正（`probe_findings_test.go`に固定）: FK の列に宣言キーを置くとサーバ製の暗黙インデックスが消えるので DROP INDEX と ADD は 1 文（1553）、参照されている列から PK を外すときも同じ、生成列が読む列の RENAME COLUMN は依存生成列の MODIFY を同じ文に（3108）、置換されるビューは追加列の後（1054）なのでビューは新規・置換ともに最後に依存順、新表の CREATE は既存表の新列・新キーの後（3734 / 6125）で既存表の新 FK は新表の後、型変更で落とす FK は改名後の表名（1146）。手作業の 2 巡目が 6 件で全部この 1 クラスだったのに対し、生成器は 1 回のスイープで倍近くを拾った。届いていない語彙: EVENT、既存表の AUTO_INCREMENT 値、文字集合・照合、パーティション、複合 FK、データ入り表（backfill・NOT NULL 追加の失敗） - 回帰コーパスはMySQL自身の`mysql-test/t/*.test`。パーサの受理率と、オラクルとの差分probeの両方に使う - 順序: パーサのスパイク（受理率で手段を裁定）→ 字句解析器 → CST→AST → スキーマローダー（CREATE TABLEの部分集合、`mysqldump`の正準形）→ アナライザーの型規則（mysqldをオラクルに差分テスト）→ テンプレート・vet・義務の結線（ここは共有部分なので薄い）。1.2の後 - TypeScriptフロントエンド。2つ目の言語フロントエンドで「核はSQLしか見ない」構想を検証する。言語非依存で共有するのは`check/postgres/analyze`、`check/postgres/schema`、マイグレーション一式、失敗モード・`One`の証明・境界の規則。言語依存はその言語のデファクトに合わせる: 呼び出し箇所の発見（TypeScript Compiler APIかtsc plugin、ESLintルール）、`R` / `P`相当の型解決（`query(sql)`）、PG型とTS型の対応表（pg / postgres.jsが実際に返す型）、ランタイム。最初の設計論点はテンプレート構文で、Goの`text/template`を持ち込まず、`sql\`...\``のタグ付きテンプレートと`${}`の断片で「有限の展開集合」を保つ方法（断片をリテラルの選択肢に限る、など）を決める。MySQLと同じく、`cmd/sqlshape/internal/vet`のPG固有型の切り出しが前提。横展開の見立て: 検査の大半（列と型の存在、失敗モード、`One`の証明、境界の規約、インジェクション保証、マイグレーション）はSQL側だけで閉じていてホスト言語の型を見ない。言語ごとに必須なのは「lintの口」「テンプレート定数の取り出し」「ランタイム」の3つで、`R` / `P`の型照合は静的型がある言語で足す層（動的型の言語では実行時の行マッピング検査か、型ヒントがあれば静的に） From 7074645eec6ec42962df97c2c3915226dceac8b4 Mon Sep 17 00:00:00 2001 From: kr9ly Date: Tue, 15 Sep 2026 15:07:01 +0900 Subject: [PATCH 089/125] PostgreSQL migrations have the same oracle as MySQL's: check/postgres/migrate's TestMigrateProbe generates schemas from the planner's vocabulary (column types, an ENUM type, identity and generated columns, unique constraints and indexes, foreign keys, CHECKs, comments, views, SQL functions, trigger functions with their triggers), mutates each into a target with its `-- @migrate` declarations, and judges the plan against the embedded PostgreSQL the way `sqlshape apply` runs it (the DDL applied to the source reads back as the target, column order aside, and a second plan is empty); 200 pairs of seed 1 are the gate. The first sweeps (about 3,000 pairs over eleven seeds) found ten classes, fixed and pinned in probe_findings_test.go: a trigger function is dropped after the table whose triggers hold it (2BP01); a type change under a generated column drops and re-adds the generated column around it (0A000); a new table's identity column creates its own sequence, not emitted a second time (0A000); new columns are added and gone columns dropped in generated-column dependency order (42703 / 2BP01); a foreign key resting on a key that goes -- the primary key moving off the referenced column, the constraint renamed with its table, or the referencing table itself going -- is dropped ahead of the key and re-added once the target's key exists (redoFK), and every table's foreign keys go before any table's other constraints; a generated-column rewrite restores the multi-column constraints, indexes and CHECKs the DROP COLUMN takes down and adds() does not add them twice (restored); the views over a table whose generated column is rewritten are recreated around it (generatedRecreates), and an expression that differs from the target's only by a declared rename is not rewritten (renamedExpr); views are replaced in adds, after the columns they may read (42703), and a view an ENUM recreation dropped is created once (42P07); readIntents reads table renames before column renames whose right side names the table as it will be. Both generators stop declaring the drop of a generated column a mutation itself added. CHANGELOG and design.md record the probe and the vocabulary it does not reach (composite foreign keys, domains and composites, partitions, RLS, materialized views, other schemas, tables with rows).

検査の大半（列と型の存在、失敗モード、`One`の証明、境界の規約、インジェクション保証、マイグレーション）はSQL側だけで閉じていてホスト言語の型を見ない。言語ごとに必須なのは「lintの口」「テンプレート定数の取り出し」「ランタイム」の3つで、`R` / `P`の型照合は静的型がある言語で足す層（動的型の言語では実行時の行マッピング検査か、型ヒントがあれば静的に） From 1958600f59ef7f8ea2610e80bcb66016f6517f22 Mon Sep 17 00:00:00 2001 From: kr9ly Date: Tue, 15 Sep 2026 16:59:53 +0900 Subject: [PATCH 090/125] Both migrate probes run against tables holding rows, with up to five mutations, composite foreign keys, and the rest of each dialect's vocabulary. Rows: three per table (integer columns carry the row number, so every reference resolves and every key is distinct; a nullable column is NULL in the third row), inserted into the source before the plan runs, so what apply runs against is never empty. Every mutation that needs rows filled declares its `-- @migrate backfill` (a column turning NOT NULL, a new NOT NULL foreign key column, the primary key moving onto an existing or a new column, a composite key's new columns on a parent with rows), declarations follow later renames of their table and column, and a mutation's own columns are never declared dropped. PostgreSQL's generator gained domains, a second schema (qualified names throughout, three-part declarations), bigserial ids and materialized views; MySQL's gained events, column collations, INVISIBLE columns, ON UPDATE CURRENT_TIMESTAMP and prefix keys. What the wider probe found, fixed and pinned in probe_findings_test.go: MySQL runs a column's declared backfill before the MODIFY that makes it NOT NULL (1138) and a new column's before the keys and foreign keys over it (1452); a new AUTO_INCREMENT column gets its key in the same ADD COLUMN (1075); every table's foreign keys are dropped before any table's keys (dropForeignKeys, 1553); readIntents reads table renames before column renames; and the schema loader keeps the closing of a versioned comment in a column's definition text (`/*!80023 INVISIBLE */`, closeVersionComment), so MODIFY COLUMN from that text parses. PostgreSQL: a comment on a renamed table is the same comment and one the target drops is removed under the new name (commentKeyTo); a serial column's sequence is renamed along with its table or column (42P01 on the plan's SET DEFAULT nextval otherwise), identity sequences left alone.

PostgreSQL reaches 90 of 102 (unreached: six note-only changes, four PostgreSQL 18 spellings the probe's 17 refuses, `~ index unique` which pg_dump never produces, `~ function window` since LANGUAGE internal functions are not tracked); MySQL 47 of 48 (partitioning, a problem rather than DDL). The vocabulary that got the generators there: PostgreSQL's row-level security, composite types, column comments, CHECK expression changes, UNIQUE NULLS NOT DISTINCT, DEFERRABLE, partial and expression indexes, EXCLUDE (btree / gist), ON UPDATE actions, identity kinds, rules, extensions, tables moving between schemas, standalone sequences, procedures, aggregates, plpgsql, trigger functions swapped, seeded rows; MySQL's live AUTO_INCREMENT on an existing table, column comments, CHECK expression changes and NOT ENFORCED, ON UPDATE / ON DELETE, FULLTEXT and SPATIAL (a POINT column type), functional and DESC key parts, INVISIBLE indexes, table CHARSET / COLLATE and ROW_FORMAT (new to the model, the diff and the plan), procedures, events' fields, ENGINE. Found, fixed and pinned in probe_findings_test.go -- PostgreSQL: an attribute type change on a composite type a column uses is refused (0A000) so the plan reports it; EXCLUDE restored after a generated-column rewrite; a policy or rule reading a retyped column is dropped around the change (0A000) and not dropped twice (42704); CREATE SCHEMA before and DROP SCHEMA after the SET SCHEMA moving tables (3F000 / 2BP01); a bigserial's sequence follows its table's SET SCHEMA (42P01), is released before its owner table drops, and is not dropped explicitly when dropped implicitly (2BP01); CREATE AGGREGATE keeps its text and a function turning procedure or aggregate is DROP + CREATE (42723). MySQL: RENAME COLUMN of a column a foreign key rests on and a stored generated column reads can be done by neither ALGORITHM (1846 / 1845), so its foreign keys are dropped around it; a MODIFY giving ON UPDATE CURRENT_TIMESTAMP runs after the backfills (1062); an INVISIBLE unique key cannot stand in for a primary key being moved (3522) and a visibility-only change is ALTER INDEX ... [NOT] VISIBLE; the canonical form of an ENUM / SET column under an explicit table CHARSET was not idempotent (a plan after apply was never empty), fixed in the loader and the diff. docs/design.md gains a "how fidelity is measured" section for migrations next to the checker's; docs/migrations.md "How the plan is tested"; README's compatibility section points at both.

PostgreSQL: the schema model carries a table's partition strategy, key text and a partition's bound (from PARTITION OF ... FOR VALUES and from pg_dump's CREATE TABLE + ALTER TABLE ONLY ... ATTACH PARTITION pair), the loader accepts ALTER INDEX ... ATTACH PARTITION (it refused every partitioned dump before), the diff reports `partition key` as () and a new `partition bound`, and the plan creates a partitioned table with its partitions attached once they exist, adds a partition to an existing parent, drops one (declared with `-- @migrate drop`, since it takes its rows), attaches and detaches (every detach before any attach, 23514), skips a partition's own constraints and indexes when a pre-existing parent already carries them (42P16 otherwise) and never alters a partition's own columns; a changed partition key or strategy on a table holding rows is a problem that stops apply, not a note. MySQL: Table.Partitioned became Table.Partitioning (RANGE and HASH structurally, the other kinds as the server's text), read from CREATE TABLE and the ALTER TABLE partition actions, compared as a table property, and planned as PARTITION BY ..., REMOVE PARTITIONING, ADD PARTITION, DROP PARTITION (declared with the new `-- @migrate drop partition
    .`), REORGANIZE PARTITION ... INTO and ADD PARTITION PARTITIONS n / COALESCE PARTITION n; partition changes run after the plan's column adds and backfills (1054). Pinned in probe_findings_test.go: a new partition's attach after its own CREATE (42P01), an owned sequence kept across its column's rename and re-owned when its old owner table goes (42P01), the automatic key on attach, MySQL's partition ordering. The probes generate and mutate partitioned tables, so the alphabet's partition entries are reached: PostgreSQL 92 of 103 (the populated table's partition key being problem-only), MySQL 48 of 48. Measured for the generators: a partitioned InnoDB table cannot hold a POINT column (1178), unique keys include the partition columns (1503), no foreign key touches it (1506). docs/design.md records the ruling: partitions are schema, handled like columns rather than left as a difference the way Skeema's partitioning=keep does, and the migration's scope extends to the operations that move rows.

ATTACH + PARTITION` (it refused every partitioned dump before), the diff reports `partition key` as + ` ()` and a new `partition bound`, and the plan creates a partitioned table with + its partitions attached once they exist, adds a partition to an existing parent, drops one + (declared with `-- @migrate drop`, since it takes its rows), attaches and detaches (every + detach before any attach, so a moving bound never overlaps a neighbour's, 23514), skips a + partition's own constraints and indexes when a pre-existing parent already carries them + (PostgreSQL builds them on attach, 42P16 otherwise) and never alters a partition's own + columns; a changed partition key or strategy on a table holding rows is a problem that stops + `apply`, not a note. MySQL: `Table.Partitioned` became `Table.Partitioning` (RANGE and HASH + structurally, the other kinds as the server's own text), read from `CREATE TABLE` and the + `ALTER TABLE ... PARTITION BY` / `ADD` / `DROP` / `REORGANIZE` / `COALESCE` / `REMOVE + PARTITIONING` actions, compared as a table property, and planned as `PARTITION BY ...` (a table + gaining partitioning or changing kind or key), `REMOVE PARTITIONING`, `ADD PARTITION` (a + `RANGE` partition appended), `DROP PARTITION` (declared with the new `-- @migrate drop + partition
    .`), `REORGANIZE PARTITION ... INTO` (a bound moved or a partition + inserted before `MAXVALUE`) and `ADD PARTITION PARTITIONS n` / `COALESCE PARTITION n` (a + `HASH` count); partition changes run after the plan's column adds and backfills (a table + partitioned by a column the same plan adds, 1054). Measured and pinned in + `probe_findings_test.go`: a new partition's attach after its own `CREATE TABLE` (42P01), an + owned sequence kept when its owning column is renamed rather than dropped and re-owned when + its old owner table goes (42P01), PostgreSQL's automatic key on attach; MySQL's partition + ordering. The probes generate partitioned tables (PostgreSQL: RANGE and LIST with a DEFAULT + partition, one row per partition; MySQL: RANGE with and without `MAXVALUE`, HASH) and mutate + them (add / drop / attach / detach / move a bound / reorganize / change a count / remove + partitioning), so the alphabet's `~ table partition of`, `~ table partition bound` and MySQL's + `~ table partitioned` are reached; PostgreSQL stands at 92 of 103 (the partition key of a + populated table being a problem-only change), MySQL at 48 of 48. A partitioned InnoDB table + cannot hold a `POINT` column at all (1178), every unique key must include the partition + columns (1503) and no foreign key may touch it (1506), measured, and the generators keep to + that. Ruling recorded in `docs/design.md`: partitions are schema, so the plan handles them + like columns rather than leaving a difference the way Skeema's `partitioning=keep` does, and + the migration's scope extends to the operations that move rows. + - The migrate probes have a coverage unit and a third round of vocabulary. `diff.Alphabet()` (both dialects) enumerates every kind of change the diff can report -- an `(Op, Kind, Field)` triple such as `+ table`, `~ column type`, `~ constraint deferrable` -- mined from the same diff --git a/check/mysql/diff/diff.go b/check/mysql/diff/diff.go index 20f67ca..5f8a8ed 100644 --- a/check/mysql/diff/diff.go +++ b/check/mysql/diff/diff.go @@ -296,10 +296,41 @@ func TableProps(t *schema.Table) map[string]string { "collation": t.Collation, "rowFormat": t.RowFormat, "comment": t.Comment, - "partitioned": fmt.Sprint(t.Partitioned), + "partitioned": PartitioningProps(t.Partitioning), } } +// PartitioningProps is a table's PARTITION BY clause, canonicalized to one comparable +// string: "" for an unpartitioned table (nil), Partitioning.Text for a clause too complex +// for this package's Kind to say more about (RANGE/LIST COLUMNS, KEY, LINEAR, LIST, +// subpartitions), else the pieces alterTable itself decides DDL from -- kind, expression +// and, in order, every partition's own name and boundary -- so two clauses this package +// tells apart the same way (an ADD PARTITION reordering nothing, say) never look changed +// on account of some detail alterTable does not look at either. +func PartitioningProps(p *schema.Partitioning) string { + if p == nil { + return "" + } + if p.Kind == "" { + return p.Text + } + var b strings.Builder + fmt.Fprintf(&b, "%s (%s)", p.Kind, p.Expr) + if p.Kind == "HASH" { + fmt.Fprintf(&b, " PARTITIONS %d", p.Num) + return b.String() + } + for _, part := range p.Parts { + b.WriteString(" " + part.Name + ":") + if part.MaxValue { + b.WriteString("MAXVALUE") + } else { + b.WriteString(part.Bound) + } + } + return b.String() +} + // ColumnProps are a column's properties: its type, its whole definition as the server // spells it (nullability, default, attributes and comment included), and its position. func ColumnProps(t *schema.Table, c *schema.Column) map[string]string { diff --git a/check/mysql/internal/mysqlast/hooks_dml.go b/check/mysql/internal/mysqlast/hooks_dml.go index c1576d4..036f43d 100644 --- a/check/mysql/internal/mysqlast/hooks_dml.go +++ b/check/mysql/internal/mysqlast/hooks_dml.go @@ -176,8 +176,12 @@ func init() { l, _ := kids[0].(List) return append(l, refPart(n, kids[2])), nil }) - // ident_string_list: ident -> [ident] + // ident_string_list: ident -> [ident]; ident_string_list ',' ident -> the list extended + // (DROP PARTITION p0, p1, a plain comma list this rule's only other alternative parsegen + // already read; only the recursive one needed a hand-written hook, measured: ALTER TABLE + // t DROP PARTITION p0, p1 failed to build without it) register("ident_string_list", "ident", listOf(1)) + register("ident_string_list", "ident_string_list ',' ident", appendTo(1, 3)) // xid: text_string -> XID(gtrid) register("xid", "text_string", build("XID", 1)) // insert_stmt: INSERT ...

Generators: a fresh enum is never the target of a label drop (42704), a fresh column never a primary key candidate (23502), a FULLTEXT-keyed table never partitioned (1214).

Coverage no longer rides on the random draw: a directed pass applies every mutation alone once per gate (PostgreSQL's mutation ceiling goes back to five, a one-way toggle is split into its two directions, `drop view` and `drop materialized view` are separate so a materialized view is always reached), and PostgreSQL's probe runs on 18 as well as 17 (TestMigrateProbe18: VIRTUAL generated columns, NOT ENFORCED, WITHOUT OVERLAPS toggled in place, PERIOD foreign keys). Both probes' generators are split into files by concern, byte-identical reports before and after. PostgreSQL's planner tracks LANGUAGE internal functions again, only a range type's own constructor left out; moves the rows a new bound no longer covers back through the parent before ATTACH PARTITION (23514 otherwise), and the rows of an independent table being attached; partitions a populated table after the fact, unpartitions it, or repartitions it -- rename, recreate the target's shape, attach the declared partitions, INSERT ... SELECT so the router places every row, drop the old table -- carrying comments, triggers, policies, rules and inbound foreign keys over, a bigserial's sequence detached with OWNED BY NONE and re-owned by the new table, an identity column's old sequence renamed aside and the new one continued with OVERRIDING SYSTEM VALUE and setval (the model's bigserial marker 's' is not an identity, isIdentity); and turns the four remaining changes without a lossless DDL (INHERITS, OF type, a domain's base type, a range's subtype) into problems that stop apply rather than notes. MySQL's planner converges a table's DEFAULT CHARSET / COLLATE change by MODIFYing every string column of implicit collation (the option alone leaves them in the old encoding and the plan after apply was never empty, measured); structures LIST like RANGE (ADD, DROP under `-- @migrate drop partition`, every changed value list in one REORGANIZE PARTITION ... INTO); and models KEY, LINEAR, ALGORITHM, RANGE / LIST COLUMNS, HASH / KEY subpartitioning and a partition's COMMENT (Partitioning.Text is gone: a form the loader does not model is a problem, a KEY count is ADD PARTITION PARTITIONS / COALESCE PARTITION, a comment a REORGANIZE, anything else a rewrite of the clause; a LIST COLUMNS value list needs double parentheses even for one column, measured). Pinned in probe_findings_test.go: a new standalone sequence owned by an existing column the plan dropped, the same sequence not created twice under a rename, an owned sequence following its table's schema move (42P01), the row moves on a bound change and on attach, the three repartition directions with row counts and an empty second plan, repartition with bigserial and with identity ALWAYS / BY DEFAULT, MySQL's charset convergence, LIST add / drop / move, KEY count and ALGORITHM, RANGE COLUMNS, subpartitioned RANGE. PostgreSQL reaches 94 of 103 alphabet entries on 17 and 98 on 18, MySQL 48 of 48; every unreached entry is a problem the plan stops on, a change that cannot appear, or 18 syntax a 17 server refuses. CHANGELOG is rewritten at Keep a Changelog granularity, 2.0.0 down to 1.1.0; the details live in the commit log, docs/design.md and the pinned tests.

Measured and pinned in - `probe_findings_test.go`: a new partition's attach after its own `CREATE TABLE` (42P01), an - owned sequence kept when its owning column is renamed rather than dropped and re-owned when - its old owner table goes (42P01), PostgreSQL's automatic key on attach; MySQL's partition - ordering. The probes generate partitioned tables (PostgreSQL: RANGE and LIST with a DEFAULT - partition, one row per partition; MySQL: RANGE with and without `MAXVALUE`, HASH) and mutate - them (add / drop / attach / detach / move a bound / reorganize / change a count / remove - partitioning), so the alphabet's `~ table partition of`, `~ table partition bound` and MySQL's - `~ table partitioned` are reached; PostgreSQL stands at 92 of 103 (the partition key of a - populated table being a problem-only change), MySQL at 48 of 48. A partitioned InnoDB table - cannot hold a `POINT` column at all (1178), every unique key must include the partition - columns (1503) and no foreign key may touch it (1506), measured, and the generators keep to - that. Ruling recorded in `docs/design.md`: partitions are schema, so the plan handles them - like columns rather than leaving a difference the way Skeema's `partitioning=keep` does, and - the migration's scope extends to the operations that move rows. - -- The migrate probes have a coverage unit and a third round of vocabulary. `diff.Alphabet()` - (both dialects) enumerates every kind of change the diff can report -- an `(Op, Kind, Field)` - triple such as `+ table`, `~ column type`, `~ constraint deferrable` -- mined from the same - property functions `Compare` uses, and the probe's gate (200 pairs of seed 1) now fails unless - every triple is produced by some pair or listed as unreachable with a reason; only "the planner - writes no DDL for it" and "cannot appear" are accepted, and a property the diff learns fails the - gate until the generator produces it. PostgreSQL reaches 90 of 102 (unreached: the six - note-only changes `INHERITS` / partition key / partition of / `OF type` / a domain's base type / - a range's subtype; four PostgreSQL 18 spellings the probe's PostgreSQL 17 refuses; `~ index - unique`, which pg_dump never produces, and `~ function window`, since `LANGUAGE internal` - functions are not tracked). MySQL reaches 47 of 48 (unreached: `~ table partitioned`, a problem the plan reports rather than DDL). The vocabulary that got the - generators there: PostgreSQL's row-level security (the flags, policies and their predicates, - commands, roles), composite types (as column types, attributes added / dropped / retyped, with - and without columns using them), column comments, CHECK expression changes, `UNIQUE NULLS NOT - DISTINCT`, `DEFERRABLE` on unique constraints and foreign keys, partial and expression indexes, - `EXCLUDE` (btree and gist, `=` and `<>`), `ON UPDATE` actions, identity `ALWAYS` / `BY DEFAULT` - and identity added or dropped, rules, extensions, tables moving between schemas, standalone - sequences and `OWNED BY`, procedures, aggregates, `plpgsql`, trigger functions swapped, seeded - rows added / changed / removed; MySQL's live `AUTO_INCREMENT=` on an existing table (ignored, - as designed), column comments, CHECK expression changes and `NOT ENFORCED`, `ON UPDATE` / `ON - DELETE` changes, `FULLTEXT` and `SPATIAL` indexes (a `POINT SRID 4326` column type), functional - and `DESC` key parts, `INVISIBLE` indexes, table `CHARSET` / `COLLATE` and `ROW_FORMAT` - (`ROW_FORMAT` is new to the schema model, the diff and the plan). What the round found, fixed - and pinned in `probe_findings_test.go` -- PostgreSQL: an attribute type change on a composite - type some column uses is refused (0A000), so the plan reports it instead of writing the DDL; - an `EXCLUDE` constraint is restored after a generated-column rewrite like the other - constraints; a policy or a rule reading a column whose type changes is dropped around the - change (0A000) and a rule is not dropped twice when a rename recreates it anyway (42704); - `CREATE SCHEMA` comes before and `DROP SCHEMA` after the `SET SCHEMA` moving tables in and - out (3F000 / 2BP01); a bigserial's sequence follows its table's `SET SCHEMA` on its own - (42P01), is released with `OWNED BY NONE` before the table it was owned by is dropped, and is - not dropped explicitly when the column or table going drops it implicitly (2BP01); `CREATE - AGGREGATE` keeps its definition text and a function becoming a procedure or aggregate is a - `DROP` and a `CREATE` (42723). MySQL: a `RENAME COLUMN` of a column a foreign key rests on and - a stored generated column reads can be done by neither `ALGORITHM` (1846 / 1845), so the - foreign keys over it are dropped before the rename and re-added after; a `MODIFY` giving a - column `ON UPDATE CURRENT_TIMESTAMP` runs after the plan's backfills, whose `UPDATE`s it would - otherwise touch (1062); an `INVISIBLE` unique key cannot stand in for a primary key that is - being moved (3522), so such keys are visible across the move and made invisible at the end, - and a key whose only difference is its visibility is an `ALTER INDEX ... [NOT] VISIBLE` (a - `DROP` + `ADD` in one statement keeps the old visibility, measured); the canonical form of an - `ENUM` / `SET` column under an explicit table `CHARSET` / `COLLATE` was not idempotent (a - second canonicalization added `CHARACTER SET`, so a plan after `apply` was never empty), - fixed in the loader and the diff. Rulings recorded in `docs/design.md` (a "how fidelity is - measured" section for migrations, next to the checker's) and `docs/migrations.md`. - -- Both migrate probes now run against tables holding rows (three per table, distinct positive - integers, a NULL in the third row of every nullable column), with up to five mutations per pair, - composite foreign keys, and the rest of each dialect's vocabulary: PostgreSQL's domains, a second - schema, bigserial ids and materialized views; MySQL's events, column collations, INVISIBLE - columns, ON UPDATE CURRENT_TIMESTAMP and prefix keys. Every mutation that needs rows filled - declares its `-- @migrate backfill`. What that found and fixed: MySQL runs a column's declared - backfill before the MODIFY that makes it NOT NULL (1138) and a new column's before the keys and - foreign keys over it (1452); a new AUTO_INCREMENT column gets its key in the same ADD COLUMN - (1075); every table's foreign keys are dropped before any table's keys (1553); a column SHOW - CREATE TABLE writes with a versioned comment (`/*!80023 INVISIBLE */`) keeps the comment's - closing in its definition text, so MODIFY COLUMN from it parses. PostgreSQL: a comment on a - renamed table is the same comment, and one the target drops is removed under the new name; a - serial column's sequence is renamed along with its table or column, since the target names it - after the new names (42P01 on the plan's SET DEFAULT nextval otherwise); `-- @migrate rename` - of a table is read before the column renames on both dialects. - -- PostgreSQL migrations have the same oracle: `check/postgres/migrate`'s `TestMigrateProbe` - generates schemas from the planner's vocabulary (column types, an ENUM type, identity and - generated columns, unique constraints and indexes, foreign keys, CHECKs, comments, views, - functions, trigger functions with their triggers), mutates each into a target and judges the - plan against the embedded PostgreSQL the way `sqlshape apply` runs it, column order aside. - Its first sweeps (about 3,000 pairs over eleven seeds) found ten orderings the server refuses - or the plan left short, each fixed and pinned in `probe_findings_test.go`: a trigger function - is dropped after the table whose triggers hold it (2BP01); a type change under a generated - column drops and re-adds the generated column around it (0A000); a new table's identity - column creates its own sequence, which is not emitted a second time (0A000); new columns are - added and gone columns dropped in generated-column dependency order (42703 / 2BP01); a foreign - key resting on a key that goes -- the primary key moving off the referenced column, the - constraint renamed along with its table, or the referencing table itself going -- is dropped - ahead of the key and re-added once the target's key exists (2BP01), and every table's foreign - keys are dropped before any table's other constraints; a generated-column rewrite restores - the multi-column constraints, indexes and CHECKs the DROP COLUMN takes down and does not add - them twice (42710); the views over a table whose generated column is rewritten are recreated - around it (2BP01), and a generated expression that differs from the target's only by a - declared column rename is not rewritten at all (RENAME COLUMN carries it); a replaced view is - created after the columns it may read (42703) and a view an ENUM recreation dropped is created - once (42P07); `-- @migrate rename` of a table is read before the column renames whose right - side names the table as it will be, whatever their line order. - -- MySQL migrations have an oracle: `check/mysql/migrate`'s `TestMigrateProbe` generates schemas - from the planner's vocabulary (column types, generated columns, keys, foreign keys, - AUTO_INCREMENT, CHECKs, views, triggers, functions), mutates each into a target (columns added, - dropped, renamed, widened, moved, re-nulled; keys, foreign keys and checks attached and - detached; the primary key moved onto an existing or a new column; tables added, dropped, - renamed; ENUM labels; views, triggers, functions) and judges the plan the way `sqlshape apply` - runs it: the DDL applied to a mysqld holding the source must read back as the target's - canonical form, and a second plan from there must be empty. Failing pairs are minimized and - written to a report (`-migrate-probe-n`, `-migrate-probe-seed`, `-migrate-probe-report`); 200 - pairs of seed 1 are the gate. Its first sweeps (3,000 pairs over eleven seeds) found seven - orderings a real server refuses, each fixed and pinned in `probe_findings_test.go`: a - declared key over a foreign key's columns replaces the index the server made for the - constraint, and its DROP INDEX and ADD must be one ALTER TABLE (1553), as must DROP PRIMARY KEY - off a column another table's foreign key references and the replacing key; RENAME COLUMN of a - column a generated column reads carries the dependent generated columns' MODIFY in the same - statement (3108); a replaced view reading a column the plan adds is created after the ADD - COLUMN (1054), so views, new and replaced, now come last in the target's dependency order; a - new table's CREATE comes after the columns and keys the tables that stay are gaining (3734, - 6125) and a staying table's new foreign keys come after the new tables; a foreign key dropped - around a type change names its table as it is after the renames (1146). - -- MySQL after a second adversarial round against a running mysqld 8.4 (7 lanes, 29 findings, each - a regression test in `adv2_*_test.go`; the surface that grew since the first round). Bodies: - dynamic SQL (`PREPARE` / `EXECUTE` / `DEALLOCATE PREPARE`) in a trigger or FUNCTION is the - server's CREATE-time refusal 1336 and two `DECLARE`s of one name in a block 1331, both schema - problems now; a bare `RESIGNAL`'s own `SET MYSQL_ERRNO` overrides the number and a bare - `RESIGNAL` outside any `HANDLER` is 1645; a `CASE` statement with no `ELSE` carries 1339 among - the body's failure modes; a routine that `CALL`s itself is 1456 (`max_sp_recursion_depth` - defaults to 0); a FUNCTION or TRIGGER `CALL`ing a PROCEDURE that returns a result set is 1415; - the "table already in use" 1442 covers the whole invoking chain (`x`'s trigger writes `y`, - whose trigger writes `x`) and a called routine's write reached through a fired trigger. Calls: - `NEW.col` is a valid `OUT` / `INOUT` argument inside a `BEFORE` trigger (no 1414); a stored - FUNCTION in a generated column, a `DEFAULT (expr)` or a `CHECK` is refused at `CREATE TABLE` - (3763 / 3770 / 3814); a nested `CALL`'s result set propagates out. Failure modes: a - multi-column `UNIQUE` is exempt from 1062 when any one column is left NULL; an omitted `NOT NULL` - column with no `DEFAULT` is 1364; a `CHECK` on a generated column is judged against writes to - its source columns; `STRICT_TRANS_TABLES` binds only transactional engines (a MyISAM table - follows the single-row / first-row rule, `x/sqlmode` distinguishes the two strict flags); - `mysql.Violates` reads a live 1442 / 1172 back. Types: `NTH_VALUE` is read (it used to reject the - statement), `LAG` / `LEAD` / `FIRST_VALUE` / `LAST_VALUE` are typed from their argument, `LAG` / - `LEAD` nullable unless a default is given; a `BEFORE INSERT` trigger's `NEW.col` of an - `AUTO_INCREMENT` column is not nullable (the placeholder 0 is there before the body runs; a - defaulted column's is, since an explicit NULL reaches the body as NULL, measured). Facts: `INSERT ... ON DUPLICATE KEY UPDATE` records its update branch as a second write and - `REPLACE` a delete beside its insert, so `pinned` and `never on delete` see them; a string - column compared to a numeric literal fixes nothing (`'5'` and `'05'` both match `= 5`); a - `HAVING` conjunct over `GROUP BY` columns with no aggregate is a fact like a `WHERE` one; a - one-element `IN (x)` is `= x` on both dialects (MySQL parses it to its own node the producer - never read; PostgreSQL's `alternatives` wanted two). Migrations: `ADD` / `DROP COLUMN` follow - generated-column dependencies; a parent key and its referencing column widened together drop - and re-add the foreign key around the two `MODIFY`s; a primary key moving off an - `AUTO_INCREMENT` column drops and adds in one `ALTER TABLE`; a renamed primary-key column is a - `RENAME COLUMN`, not a `DROP PRIMARY KEY` (the drop side now translates the rename as the add side - did); a new table's own `AUTO_INCREMENT=n` reaches the `CREATE TABLE` (an existing table's counter - is still not compared). `mysqltest.Start` errors when the server's `lower_case_table_names` - differs from the declaration (a declared `2` on a case-sensitive filesystem starts at `0`, docs - say so now); docs say length / range / `ENUM` truncation is a type matter, not a failure mode. -- PostgreSQL after a third adversarial round against a running server (8 lanes, 23 findings, each a - regression test in `adv_*_test.go`), the failure modes first. `TRUNCATE` of a table another table's - foreign key still references (no `CASCADE`, the referrer not in the list) is reported as certain to - fail (0A000); `ON CONFLICT (cols)` absorbs a unique constraint only when it can be the arbiter, so a - `DEFERRABLE` key (55000) or a partial index whose predicate the `ON CONFLICT ... WHERE` does not - repeat (42P10) keeps its 23505 in the list, and `ON CONFLICT ON CONSTRAINT DO UPDATE` - is reported as certain to fail (42809); `ON CONFLICT DO NOTHING` without a target absorbs the - exclusion constraints and partial unique indexes too, and is certain to fail (55000) when any - key of the table is `DEFERRABLE`. A `NOT NULL` that a domain, not the column, declares is - keyed by the domain's name (schema-qualified unless public): PostgreSQL reports no table or column - for it, and `postgres.ConstraintError.Key()` now returns the domain's name for that error, so - `Violates(err, "email")` matches what the checker predicted. `ORDER BY` / `GROUP BY` resolve an - output name the way PostgreSQL does: two output columns of one name are ambiguous (42702) unless - they are the same expression; the ungrouped-column error names its table (`"t1.v"`); an error the - select list and the `WHERE` share is reported at the select list's position. The result of a - set-returning function in the select list (`unnest(arr)`) is nullable whatever its argument is: - an element can be NULL when the array cannot. The `One` proof sees through a cast on the grouped - column, takes a one-element `= ANY(ARRAY[v])` and a `NOT NULL` column's `IS NOT DISTINCT FROM v` - for equalities, and matches a partial index's predicate with the literal casts a statement spells - out; `col = NULL` fixes nothing (it is never true), so it neither pins nor proves single, on MySQL - too. `SET col = DEFAULT` stores the column's literal default, so a `transitions` declaration - judges it as a transition to that state (a non-literal default is refused as before, with a - message that says why). `-strict` rejects `[]T` / `[N]T` for an array whose Go element cannot be - NULL (`integer[]` into `[]int32`, a composite array into `[]Item`), and both modes note that - PostgreSQL never promises an array's elements are non-null even when the column is; `interval` - into `time.Duration` carries a Lossy note (a month flattened to 30 days disagrees with the - server's calendar arithmetic). vet no longer skips a `sqlshape.Query[R, P]` called through a - package-level variable (`var q = sqlshape.Query[R, P]; q(...)`), and checks the fields an `{{if}}` - reads through a nested call (`{{if gt (len .Xs) 0}}`) against `P`. Migrations: rewriting a - generated column's expression, or its `STORED` / `VIRTUAL` kind (PostgreSQL 18), drops and restores - the indexes, constraints and referencing foreign keys the `DROP COLUMN` would take with it, instead - of losing the index or emitting DDL the server refuses (2BP01); a kind-only change is no longer a - no-op. An `unfiltered` / `waive` written above a `CREATE TABLE` is told where it belongs. Kept as - they were, and now written down: `paired` requires the write, not matching values; `RETURNING` a - `sensitive` column is reading it. - -- `pgtest` and `mysqltest` are sqlshape's own test tooling, like `check/*`: they boot a real server - for the examples, the oracles and the conformance tests, and carry no compatibility promise. An - application tests its database with the server it runs on; the agreement between the checker - and the server is sqlshape's to keep. The documentation no longer presents them as part of the - API, and is reorganized for a reader who uses one database: `docs/postgres.md` and - `docs/mysql.md` gather what is each database's (the declaration, the Go type table, the - constraint names and error numbers, the runtime, what has no counterpart), the README has a - quickstart per database, and `checks.md` / `runtime.md` are written for both. - -### Added - -- `sqlshape.Error(code)` mirrors a schema's `-- sqlshape: error = ` annotation (a - trigger's or routine's own raised failure mode) in Go: `var OrderTooLarge = - sqlshape.Error("30001")`. `go vet` checks it both ways -- the declaration's code must be one the - schema declares under that exact Name, no two declarations in a package may claim the same code, - and every named failure mode a package's statements can raise must have such a declaration - somewhere the checker can reach (a Fact carries the binding across packages, the way a declared - type's does). An expect line may spell the failure by its code or by the Name, whichever reads - better. `postgres.Violates` / `mysql.Violates` now take any `~string`, so a declared - `sqlshape.Failure` reads the same as the raw code always did; neither reads the schema, so they - judge only by the code the value holds, never by Name. The PostgreSQL runtime wraps a custom - SQLSTATE into `ConstraintError` for any statement with an expect line at all now (it cannot - resolve a Name back to the code the checker matched statically). `examples/3-database-api`, - `examples/4-everything` and `examples/5-mysql` declare their triggers' and functions' errors this - way and test `Violates` against a running server. - -- `sqlshape diff`, `apply` and `verify-schema` work on a MySQL schema. Both sides are read as the - server's own `SHOW CREATE TABLE` / `SHOW CREATE VIEW`, parsed by the loader that reads - `schema.sql`; the target is canonicalized in a scratch database on the `-db` server (dropped when - done), or on a `mysqld` from `PATH` with `-from`. Compared: tables, columns (their position - included, which the plan settles with `MODIFY COLUMN ... AFTER`), keys, foreign keys, checks and - views; not seeded rows. The plan emits MySQL's own definitions; `-- @migrate` - is the same grammar, with `enum` naming the ENUM column. `apply` runs statement by statement - (MySQL's DDL commits implicitly) and reports the statement that failed. The MySQL analyzer now - rejects an expression the server rejects in an INSERT's or UPDATE's value (`SET total = nope`, - 1054) instead of typing it as unknown. -- MySQL: `CREATE TRIGGER` / `CREATE PROCEDURE` / `CREATE FUNCTION` (`DEFINER`, `IF NOT EXISTS`, the - characteristics), and `DROP` / `ALTER` of each, are read by the schema loader with no `DELIMITER` - needed (a compound body's own `;` is read as one statement; a mysql-client `DELIMITER x` line is - read too), the server's own CREATE-time refusals reported as problems (no such table 1146, - already exists 1359 / 1304, no such trigger or routine 1360 / 1305, no such `FOLLOWS` / - `PRECEDES` anchor 3011); `DROP TABLE` takes a table's triggers, `RENAME TABLE` moves them. - `-- sqlshape: error = ` above a trigger or routine names its failure mode, the way - it already does for PostgreSQL. Migrations read triggers and routines back with `SHOW CREATE - TRIGGER` / `PROCEDURE` / `FUNCTION` (`DEFINER` dropped; a trigger's `FOLLOWS` synthesized from - `information_schema` since `SHOW CREATE TRIGGER` never spells one), diff compares them by - definition text, and the plan replaces a changed one with `DROP` + `CREATE` (MySQL has no - `CREATE OR REPLACE TRIGGER`) in dependency order: a trigger's `DROP` before its table's, a - routine's `CREATE` before the views and tables, a trigger's `CREATE` after the backfills so it - does not fire on the migration's own writes. -- MySQL: the checker reads trigger and stored routine bodies once per schema (cached, so a - routine called from several statements or firing several triggers analyzes once). `NEW.col` / - `OLD.col` type as the trigger's own table's columns (unknown column 1054, the wrong row for the - event or timing 1362 / 1363 -- a `NOT NULL` column's `NEW.col` can still be NULL in a BEFORE - trigger, measured); a `DECLARE`d variable or a routine's parameter shadows a column of the same - name. `IF` / `CASE` / `LOOP` / `WHILE` / `REPEAT`, labelled blocks with `LEAVE` / `ITERATE`, - `RETURN`, `SET`, `SELECT ... INTO`, cursors, `CALL`, `SIGNAL` / `RESIGNAL` and - `DECLARE ... HANDLER FOR` are walked, with the server's own CREATE-time refusals (1308, 1313, - 1320, 1324, 1327, 1328, 1222, 1415, 1422) reported on the definition; a trigger writing its own - table is 1442 on every one of the 18 timing x event x write combinations (measured). A statement - on a table takes the SIGNALs of its triggers for its event (`REPLACE` fires the INSERT and - DELETE triggers, `ON DUPLICATE KEY UPDATE` the INSERT and UPDATE ones, measured), the constraints - the trigger's own writes may violate, and what those writes fire in turn (a cycle is cut). A - SIGNAL's key is its `MYSQL_ERRNO` in decimal when it sets one, else its SQLSTATE (SQLSTATE class - `01` a warning, an unhandled `02` 1643, anything else unhandled 1644); a named `CONDITION` - resolves to its value. A `DECLARE ... HANDLER FOR` absorbs the matching failure modes of its - block (`SQLEXCEPTION` everything but the `01` and `02` classes, `SQLWARNING` / `NOT FOUND` their - class, a SQLSTATE or number itself); `INSERT` / `UPDATE IGNORE` absorbs none of a trigger's - SIGNALs (measured). `SELECT ... INTO` carries 1172 unless the query is provably at most one row. - A call to a stored FUNCTION the catalog does not know resolves to the schema's (an unqualified - name that is also a native function is the native one, as on the server; `db.f` names the - routine), typed from `RETURNS` (always nullable), taking 1318 for a wrong argument count and - 1305 for no such routine, and bringing the body's own failure modes to the calling statement; a - function that writes a table the statement already references is 1442 on every run (reading the - table is enough, measured). `CALL p(...)` analyzes `IN` / `INOUT` arguments by the parameters, an - `OUT` argument must be a variable (1414; a `?` is one), facts `Kind Call`, the result columns - from the body's own INTO-less `SELECT`s when they agree (none: no columns; several of different - shapes: the checker's own error), and the body's own failure modes. Cross-checked against a - running `mysqld`. -- The MySQL runtime: a SIGNAL raised by a trigger or routine comes back as a `ConstraintError` - whose `Key` is the SQLSTATE when the server numbers it itself (1644, 1643), or the decimal - `MYSQL_ERRNO` when the SIGNAL set its own error number; `Violates(err, "45000")` / - `Violates(err, "30001")` read like the checker's own keys. A `01xxx` SIGNAL is a warning and the - statement succeeds. -- The schema declares the server settings its judgments depend on, one per line next to the - version: `-- sqlshape: server sql_mode = 'ANSI,STRICT_ALL_TABLES'`, - `-- sqlshape: server lower_case_table_names = 1`. MySQL reads these two (any other variable, a - mode 8.4 does not have, or a value out of range is a problem of the schema; PostgreSQL reads no - variable yet and reports each one). The checker follows them: the parser's bits - (`ANSI_QUOTES`, `PIPES_AS_CONCAT`, `IGNORE_SPACE`, `NO_BACKSLASH_ESCAPES`, - `HIGH_NOT_PRECEDENCE`, `REAL_AS_FLOAT`), `ONLY_FULL_GROUP_BY` for the group check, strict mode - for the nullability of string functions and the 1048 failure mode (without it only a single-row - `INSERT` / `REPLACE` rejects a `NULL`), `NO_UNSIGNED_SUBTRACTION`, and `lower_case_table_names` - for how table and view names compare (1 lower-cases them, 2 ignores case). Without a - declaration the checker assumes the server's defaults, as it did. `mysqltest.Start` passes the - declared variables to `mysqld`, so the application's tests and the analyzer's conformance - tests run under the declared mode (22 statements and 6 writes verified against 8.4 under - `''`, `ANSI` and `NO_UNSIGNED_SUBTRACTION`); `mysql.Verify(ctx, db, schemaSQL)` compares a - connection's session `@@sql_mode` and the server's `lower_case_table_names` with the - declaration. `x/sqlmode` holds MySQL's sql_mode names and bits. -- `mysqltest.Start` fails as soon as `mysqld` exits (an option it rejects) instead of waiting a - minute, and quotes the `[ERROR]` lines of its log. -- MySQL: an aggregate without `GROUP BY` proves one row wherever the aggregate sits in the - select list or `HAVING` (`COALESCE(SUM(total), 0)`, `COUNT(*) + 1`, `MAX(id)` alike), not only - when every select item is a bare aggregate call, so a `SELECT COALESCE(SUM(x), 0) INTO v` in a - routine no longer carries 1172 and the same query passes `One`. Which aggregates are the - block's own is the group check's answer (a subquery's aggregate over its own columns leaves the - outer query one row per input row, as before). -- MySQL: `CREATE EVENT` is read (both schedule forms, `STARTS` / `ENDS`, `ON COMPLETION`, the - status, `COMMENT`), `ALTER EVENT` (each clause replacing its part, `RENAME TO` included) and - `DROP EVENT` are applied. An event's body is analyzed like a routine's: a table it names that the - schema does not have is a schema problem (the server accepts it at CREATE time and fails at every - run, measured), its statements are judged for the obligations, a `RETURN` is 1313. `diff` / - `apply` / `verify-schema` manage events: read back through `SHOW CREATE EVENT`, compared by - schedule, bounds, options and body, a changed one a `DROP EVENT` and a `CREATE EVENT`. A time - `schema.sql` leaves to the server (an omitted or computed `STARTS`, a computed `AT`) is not - compared, since the server fills it in at creation and reads it back as a literal (measured); - a literal time is compared as written. Formerly `CREATE EVENT` was refused by the loader. -- MySQL: a qualified function call, `db.f(...)`, names the schema's own FUNCTION even when a - native function has the same name (an unqualified `abs(-1)` is still the native one, `db.abs(-1)` - the schema's, `db.nope(1)` 1305; measured), where it used to type as the native function. The - 1442 overlap check now also counts a table the statement names in `FROM` without reading a - column of it, follows writes through nested calls (a function that `CALL`s a procedure writing - t, or `RETURN`s a function that does), runs per statement inside a trigger's or routine's body - (`UPDATE t SET v = f(v)` with f writing t is 1442 when the routine is `CALL`ed; two separate - statements are not), and counts a trigger's own table against every statement of its body (a - trigger calling a function that writes the trigger's table is 1442, as a direct write already - was); a `CALL` inside a body is resolved like a top-level one (1305 / 1318 / 1414) and the - callee's failure modes and writes become the body's. All measured against mysqld 8.4 - (`TestNestedCallsServer`). An AFTER trigger's `NEW.col` following the column's declared - nullability is now measured rather than inferred. +- MySQL 8.4. A `schema.sql` that declares `-- sqlshape: mysql 8.4` is checked by a MySQL + analyzer: the parser and lexer are the server's own, the function catalog is read from the + server's source, and the verdicts (types, nullability, errors, the `ONLY_FULL_GROUP_BY` check) + are measured against a running `mysqld`. `One`, the obligations and the failure modes work + through the same contract PostgreSQL uses, with the constraints named as MySQL reports them + (`PRIMARY`, `orders_ibfk_1`, `t_chk_1`) and `INSERT IGNORE` / `ON DUPLICATE KEY UPDATE` / + `REPLACE` judged as the server runs them. What has no MySQL counterpart is listed in + [docs/mysql.md](docs/mysql.md). +- MySQL triggers, stored procedures and functions, and events: their bodies are analyzed + (`NEW` / `OLD`, variables, control flow, cursors, `SIGNAL` / `RESIGNAL` / `HANDLER`, `CALL`), + a statement inherits the failure modes of the triggers it fires and the routines it calls, + and the server's own refusals (a trigger writing its own table, 1442, among them) are + reported. `-- sqlshape: error = ` names a raised error, as on PostgreSQL; + `-- sqlshape: not null` above a `CREATE FUNCTION` declares it never returns NULL. +- `sqlshape.Error(code)` declares a schema's named error in Go (`var OrderTooLarge = + sqlshape.Error("30001")`); `go vet` checks the declaration against the schema both ways, an + expect line may use the Name, and `Violates` accepts the value. +- `-- sqlshape: server = ` declares the server settings the checker's judgments + depend on (MySQL: `sql_mode`, `lower_case_table_names`); the checker follows them, and + `mysqltest.Start` starts the server with them. +- The MySQL runtime, `github.com/kr9ly/sqlshape/mysql/v2` (`Run`, `Collect`, `First`, `Exec`, + `Get` / `Find` / `ExecOne`, `ConstraintError`, `Violates`) over `database/sql`, and + `github.com/kr9ly/sqlshape/mysqltest/v2`, which boots the `mysqld` on `PATH` with the + application's schema. `examples/5-mysql` shows the whole path. +- `sqlshape diff`, `apply` and `verify-schema` on MySQL: both sides are read as the server's own + `SHOW CREATE` output, the target canonicalized in a scratch database on the same server, and + the plan written in MySQL's own DDL, statement by statement. Tables with their options, + columns with their position, keys, foreign keys, checks, views, triggers, routines, events + and partitions are compared; seeded rows are not. +- Partitions are migrated on both dialects: a partitioned table is created, a partition added, + dropped (under a `-- @migrate drop` declaration, since it takes its rows), attached, detached, + its bound moved with the rows that no longer fit moved along, and a populated table can be + partitioned after the fact, unpartitioned, or repartitioned, the rows redistributed by the + server. MySQL covers `RANGE`, `LIST`, `COLUMNS`, `HASH`, `KEY`, `LINEAR` and subpartitioning, + with `-- @migrate drop partition
    .` for a partition that goes. +- The migration planner is tested against a real server the way the checker is: generated + schema pairs, every kind of change the diff can report, applied with rows in the tables on + PostgreSQL 17 and 18 and on MySQL 8.4, with the plan required to land on the declared schema + and leave nothing to plan afterwards ([docs/migrations.md](docs/migrations.md#how-the-plan-is-tested)). + The orderings and omissions this found are fixed and pinned as regression tests. +- Row-level security, composite types, rules, extensions, schema moves, standalone sequences, + procedures, aggregates, `EXCLUDE`, partial and expression indexes, `NULLS NOT DISTINCT` and + `DEFERRABLE` are handled by the PostgreSQL migration plan; `FULLTEXT` / `SPATIAL` / functional + / `INVISIBLE` keys, `ROW_FORMAT`, table charset changes and column comments by MySQL's. +- `x/dialect.Type.ElemNotNull`: an array whose elements are provably not NULL + (`array_agg((a, b)::t)`, an inner-joined `NOT NULL` column) binds to `[]T` without the "may + contain a NULL element" note; `col:",notnull"` on an array field asserts the elements too. +- `-query=pkg.Func,pkg.Other:one` registers a program's own marker functions, read like + `Query` / `One`. +- Every example in `docs/` runs as a test: the checker must produce exactly the diagnostics the + docs claim. ### Changed - The checker is the product; the runtime is a library per database. The root module - `github.com/kr9ly/sqlshape/v2` now holds only the declarations (`Query`, `One`, `Stmt`, `Render`, - the row-binding rules) and has no dependencies. Running a statement on pgx is the module - `github.com/kr9ly/sqlshape/postgres/v2`: `postgres.Run(ctx, db, stmt, p)`, `Collect`, `First`, - `Exec`, `Get` / `Find` / `ExecOne` for `One`, and `MatView`, `Copy`, `Batch`, `LoadUserTypes`, - `ConstraintError`, `Violates`, `ErrNoRows` moved there (the methods `stmt.Run(ctx, db, p)` are - gone: a module cannot add methods to another's type). `Labelled` and `UnknownLabelError` stay in - the root. `pgtest` is its own module. The PostgreSQL analyzer and migration tools are the module - `github.com/kr9ly/sqlshape/check/postgres/v2`, the MySQL analyzer `check/mysql` (was `mysql`); - both are tool-facing, imported by the binary and `pgtest`. An application's go.mod carries the - root, its runtime and its own driver, nothing of the checker's. -- The markers the checker recognizes are configurable: `-query=pkg.Func,pkg.Other:one` registers - a program's own generic marker functions, read like `Query` / `One`. A program may run its - statements through a runtime of its own; what only sqlshape's runtime promises (the rendered SQL - is the checked SQL, violations come back under the expect line's names, `One` rejects a second - row) is stated in docs/runtime.md. -- The `One` proof is written once, over the statement's facts, for every dialect: the - PostgreSQL analyzer no longer proves cardinality on its own tree but records what the proof - needs (unique keys with a partial index's predicate, temporal keys, a view's or subquery's - body with its output columns, GROUP BY terms, LIMIT / VALUES / set-operation shape). Two - verdicts change: a `GROUP BY 1` (an ordinal, or an alias) names an output column and is no - longer read as a pinned constant, so such a statement is not proved single; a `LIMIT 1` - over a `UNION` and an aggregate over a `FULL JOIN` are one row and are proved. - -### Added - -- The MySQL runtime, `github.com/kr9ly/sqlshape/mysql/v2`: `Run` / `Collect` / `First` / - `Exec`, `Get` / `Find` / `ExecOne`, over `database/sql` with go-sql-driver/mysql; `{{.X}}` - becomes `?` on the wire with the arguments in placeholder order, rows map by the shared - binding rules, a constraint violation is a `ConstraintError` under the schema's name for it - (`Violates(err, "users_email_key")`). `github.com/kr9ly/sqlshape/mysqltest/v2` boots the - `mysqld` on PATH with the application's schema for its tests (the analyzer's oracle runs on - it too). `examples/5-mysql` shows the whole path. -- `One` on MySQL, and the proof it rests on written once for every dialect: the analyzer - records a statement's facts (`x/facts`: leaves with their unique keys, the equalities of - WHERE and of the joins, what they fix) and `x/cardinality` proves from the facts alone that - at most one row is touched — a unique key fixed by equality, carried across joins, a - derived table proved inside, an aggregate without GROUP BY, `LIMIT 1`, a single `VALUES` - row. The MySQL analyzer also resolves `ORDER BY`, `GROUP BY` and `HAVING` the way the - server does: positions, select-list aliases, a table column shadowing an alias in - `GROUP BY`, `HAVING` reaching the select list; unknown names are reported in MySQL's - words (`in 'order clause'`, `in 'group statement'`, `in 'having clause'`). -- The obligations and the failure modes on MySQL, through the same contract PostgreSQL uses. - The `-- sqlshape:` directives above a `CREATE TABLE` / `CREATE VIEW` (`require ...`, - `aggregate`, `context`, `sensitive`, `transitions`, `visible where`; a view's `unfiltered` / - `waive`) are read by the MySQL schema loader, a declared predicate is typed against the - table by the MySQL analyzer, and every statement (and every view body) is judged: the - analyzer now records the columns a statement uses, the nested blocks (derived tables, CTE - bodies, the subqueries of its conditions, the arms of a set operation) and what a write - stores. `-- sqlshape: expect` on MySQL: a write may violate a `PRIMARY` / `UNIQUE` key - (MySQL error 1062; a key the server numbers itself, or one left NULL, cannot), a `FOREIGN - KEY` (1452 from the child, 1451 from the parent it still refers to, following `ON DELETE / - UPDATE CASCADE`), a `CHECK` (3819) and NOT NULL (1048, `table.column`, dropped when the Go - type cannot be nil); `INSERT / UPDATE / DELETE IGNORE` violates nothing and `ON DUPLICATE - KEY UPDATE` absorbs the insert's unique violations. The constraints are named as the server - reports them (`PRIMARY`, `orders_ibfk_1`, `t_chk_1`), verified against a running `mysqld`; - `mysql.Violates(err, "users.name")` matches a NOT NULL violation by that spelling. -- The MySQL server's checks on a grouped, aggregated or `DISTINCT` block, as sql_mode - `ONLY_FULL_GROUP_BY` runs them (`Group_check`): a select-list, `HAVING`, `ORDER BY` or window - `PARTITION BY` / `ORDER BY` expression must be a `GROUP BY` expression, an aggregate, or made - of columns functionally dependent on the group columns -- through a table's `PRIMARY` / - `UNIQUE` key (a nullable key column only where a conjunct rejects its NULL), the `WHERE` and - inner-join equalities `col = col` and `col = constant` (a literal or an outer reference; not a - parameter), an outer join's `ON` into its nullable side (a `WHERE` that rejects the nullable - side's NULL makes the join inner, a non-deterministic `ON` gives nothing), and a derived - table's, view's or CTE's body seen through its outputs; `ROLLUP` allows only the group - expressions themselves. MySQL error 1055 with `GROUP BY`, 1140 for an aggregated query without - it (whose `ORDER BY` the server drops unchecked). With them the rules the check rests on: a - column named outside an aggregate in `HAVING` must be a select-list column or alias or a `GROUP - BY` column (1054, also for a nested query's reference to it), with `DISTINCT` an `ORDER BY` - expression not in the select list may read only select-list columns (3065), and an aggregate in - the `ORDER BY` of a query that aggregates nowhere else (3029) or of a set operation (3028) is - rejected. 376 statements agree with a running `mysqld`. The derived leaves of the facts now - carry `Outputs` on MySQL too, so `One` looks into a derived table's or view's body. -- MySQL: a parenthesized join as a side of a join, a set operation's `ORDER BY` expression - (typed against the result columns), `x NOT IN (subquery)`, `QUALIFY` rejected as 8.4 does - without the hypergraph optimizer (6037), `<=> ALL / ANY` as the syntax error it is (1064). - The facts record an `EXISTS` or single-column `IN` subquery conjunct as an Exists predicate - carrying the body (a correlated reference to the enclosing block is an Outer term), so the - obligations judge the body under its predicate; the conjuncts the server folds away (`WHERE 1 - = 1`) are dropped; a view body's positions are cleared. A MySQL placeholder carries the table - column it stands for (compared with, or stored into), so vet binds Go named types to key - identities and diffs `ENUM` labels against typed constants on MySQL too. `REGEXP_LIKE` is a - bigint(1), `REGEXP_REPLACE` nullable, `QUOTE` of a binary a character string: the probe - golden has no disagreement left. -- MySQL, after an adversarial round against a running mysqld (7 lanes, 21 findings, every one - a regression test now): a `USING` or `NATURAL` join coalesces its common columns (an - unqualified name is not ambiguous, `SELECT *` lists it once); `GROUP BY` on the alias of an - aggregate is 1056; multi-table `DELETE t1, t2 FROM ...` / `DELETE FROM t1 USING ...` is - analyzed, its targets judged for the failure modes; the select list is resolved before the - `WHERE`, as the server does, so its error comes first; a `BIT` operand is unsigned in - arithmetic; `WITH ROLLUP` makes every non-aggregated result column nullable; `STR_TO_DATE` - follows a literal format into `DATE` / `TIME` / `DATETIME`; `col -> 'path'` and `->>` parse. - The facts no longer take an expression bound to the execution (`RAND()`) for a known value, - so `GROUP BY RAND()` is not one row and `tenant_id = FLOOR(RAND() * 3)` pins nothing. The - failure modes: `REPLACE` violates no key but may violate a referencing foreign key (1451), a - multi-table `UPDATE` judges each assignment against its own table, an `UPDATE` through an - updatable view judges the base table (its parameters carry the base column too). The - schema loader names unnamed `CHECK` and `FOREIGN KEY` constraints the server's way, one above - the highest generated number, so `ALTER TABLE ... DROP CHECK t_chk_1` finds its constraint, - and reads table and view names case-sensitively (lower_case_table_names=0). The runtime's - `ExecOne` accepts the 0 / 1 / 2 rows `INSERT ... ON DUPLICATE KEY UPDATE` and `REPLACE` - report for the one row their key names. -- MySQL, a first slice. A `schema.sql` that declares `-- sqlshape: mysql 8.4` is loaded by the - MySQL schema loader and every `Query` is judged by the MySQL analyzer: the statement's own errors - (unknown table or column, ambiguity, syntax, with MySQL's message and error number), result - columns against `R` by name, type and nullability, parameters against `P` where their context - types them (compared with or assigned to a column, `LIMIT`, the argument positions a function - declares). Single-block SELECT, INSERT, UPDATE and DELETE over base tables. Expressions are typed - by the server's own rules, read out of its source: arithmetic promotion (`Item_num_op`), `CASE` / - `IF` / `COALESCE` / `GREATEST` through `field_type_merge`, casts, aggregates, and every function of - the native registry through its Item class family and `resolve_type` facts, so a `SUM` is a - nullable decimal, a comparison a `bigint(1)` a Go `bool` can carry, `LENGTH(?)` types its - placeholder as a string. The rules are checked against a real mysqld (a local test, not a CI - dependency): every registry function over representative argument types, 5,267 statements, - agrees with the server on type and nullability but for 10. Subqueries (scalar, `IN`, `EXISTS`, - `ANY` / `ALL`, correlated), derived tables (`LATERAL` too), views, common table expressions - (recursive too), `UNION` / `EXCEPT` / `INTERSECT` and `INSERT ... SELECT` are analyzed with the - server's rules for what they produce: a scalar subquery is NULL unless its query is guaranteed a - row, a recursive CTE's columns are always nullable, a derived table the server materializes - retypes a small integer expression to an int, a merged view is updatable. What has no rule yet - (user variables, the temporal hybrids such as `ADDTIME`) is accepted with a note; `One`, - `MatView`, `Copy` and the obligations are not supported yet.

Measured on 17 and 18: DETACH PARTITION strips an inherited identity (the column is left plain NOT NULL) and leaves a bigserial's DEFAULT pointing at the parent's sequence; a table with its own identity column cannot be attached until ALTER COLUMN ... DROP IDENTITY (55000), a plain column inherits the parent's identity on attach, and a table with its own bigserial attaches as it is; the row-moving INSERT before an attach needs OVERRIDING SYSTEM VALUE under a GENERATED ALWAYS parent even when it moves no row (428C9). The plan drops the identity before such an attach, does not drop it again after a detach that already did (55000), never treats the model's bigserial marker as an identity difference, and adds OVERRIDING SYSTEM VALUE. The generator renders a detached child the way pg_dump does (a plain column, or `bigint DEFAULT nextval('_id_seq')`), attaches and detaches children of every id kind, and checks that an INSERT omitting the id continues the sequence afterwards.

Trigger chains: a certain failure found anywhere along the chain -- a CALLed routine writing back through another table's trigger (1442), a self-recursive routine reached from a trigger (1456) -- is reported on the firing statement instead of being dropped with the chain's analysis, and a locking read (SELECT ... FOR UPDATE / FOR SHARE / LOCK IN SHARE MODE) of a table in use up the chain is 1442 like a write (a plain read is not, measured). Bodies: FLUSH in a trigger or FUNCTION is 1336, a SQLSTATE literal of other than five characters 1407 at CREATE (mirrored in schema.Load like 1331), SIGNAL ... MYSQL_ERRNO = 0 is 1231, a FUNCTION calling itself 1424 on every call (the CREATE goes through), and `-- sqlshape: server max_sp_recursion_depth = n` is read, above 0 turning off the 1456 prediction for a PROCEDURE's self-recursion. Facts: a string column compared to TRUE or to a CAST to a numeric type fixes nothing (the same coercion as a numeric literal, two rows updated, measured), `(a, b) IN ((?, ?))` is two equalities, an unqualified column of a USING join resolves to the coalesced column so it pins both sides, and MySQL's constants are spelled the way PostgreSQL's are (a kind letter and the bare value; facts.Term.Const documents the contract) so `transitions` reads them. Obligations: `require single` on an UPDATE or DELETE asks about the target leaf alone (cardinality.TargetSingle), so a join that only filters no longer breaks the proof. Views: OR REPLACE and ALGORITHM were never read (the keyword-only grammar rules folded to nothing; hooks added), so CREATE OR REPLACE VIEW was a spurious problem and a TEMPTABLE view was written through; WITH CHECK OPTION on a view the server would not merge is refused at load as the server's 1368 (mysqlast.Mergeable, shared with the analyzer). Runtime: a SIGNAL impersonating a builtin number (SQLSTATE '23000', MYSQL_ERRNO = 1062) keeps that number as its key.

The migrate probes judge eight pairs at once on both dialects, the PRNG's draws kept sequential so the report is byte-identical (PG 172 s to 42 s, MySQL 32 s to 19 s; MySQL's directed pass shares the PRNG with the judging and stays serial). The PostgreSQL oracle's runtime directory moves to /dev/shm like mysqltest's (SQLSHAPE_ORACLE_DIR overrides; pgtest 7.3 s to 5.3 s). check/mysql/migrate 328 s to 24 s, check/mysql/internal/analyze 94 s to 13 s, check/postgres/migrate 219 s to 59 s.

The analyzer types LOAD DATA as an INSERT of the file's rows (a view target 1288, the column list against the table, `@var` fields assigning nothing, SET expressions typed and placeholders taking the column's type; a NULL field for a NOT NULL column is 1263 not 1048, an omitted NOT NULL column takes the implicit default rather than 1364, IGNORE / REPLACE as INSERT's, all measured), LOCK TABLES (1146, 1066, the tables as read leaves; UNLOCK TABLES resolves nothing), SELECT ... INTO OUTFILE / DUMPFILE as the SELECT without columns; inside any body LOCK / UNLOCK / LOAD DATA / ALTER VIEW are the grammar's 1314 for every routine kind (OUTFILE is allowed even in a trigger or function, measured), mirrored at load like 1331. The loader applies ALTER VIEW as a whole replacement (1146 / 1347 / 1368 measured). TestCorpus guards that the hooked rules do not return to the missing list; the server test pins every measured code, LOAD DATA's on real files. Docs (en / ja): a "statements without a result set" section, ALTER VIEW under Views, the 1314 row; CHANGELOG [2.0.0].

Each statement's rows are also checked against the generator's own evaluation, so a wrong evaluator is a generator failure, not a finding; a claim the judge cannot evaluate is reported as unverified. An alphabet of 41 claim shapes is tallied and gated per dialect against a known-unreached list. Drivers: check/postgres/dialect and check/mysql/dialect TestFactsProbe (400 statements in 7 s on PostgreSQL 17, 300 in 11 s on MySQL 8.4). The first run found one hole per dialect, both fixed and pinned: MySQL accepted an UPDATE / DELETE whose subquery reads the target table (1093 in WHERE, EXISTS or IN alike; a derived table over it is materialized and allowed, INSERT ... SELECT from its own table too, all measured) or a view over it (1443) -- analyze.targetInSubquery, with the SET scalar subquery left unchecked since the facts do not record it; PostgreSQL recorded a subquery's reference to a joined table's column as a Known term when the subquery sits in the join's ON clause (the join's sides live in the passthrough scope the ON is analyzed in, not yet in the level's items), where an Outer term was meant -- facts.go's outerRef now reads the passthrough chain.

INSERT IGNORE / REPLACE / ON DUPLICATE KEY UPDATE on MySQL, ON CONFLICT DO NOTHING / DO UPDATE on PostgreSQL), runs each against fresh tables and requires every constraint error the server raises to be one of the analyzer's predicted violations under a key the runtime's Violates matches after WrapError, or a failure the analyzer already reports as certain (PostgreSQL's "every execution fails" note for an omitted NOT NULL column, which MySQL predicts as a 1364 violation instead). 300 writes pass on each dialect. postgres.WrapError and mysql.WrapError are new: the wrapping Run / Exec apply, for an error from a statement run outside them. Drivers: check/postgres/dialect and check/mysql/dialect TestFailureProbe, each check module now requiring its runtime module. Docs (runtime, mysql; en / ja) name WrapError; design.md and CHANGELOG [2.0.0] extend the probe's entry.

SET NEW.col / SET OLD.col outside a trigger is 1193 "Unknown system variable" (a read of NEW.col there is a run-time column reference and passes, measured); and a FUNCTION with no RETURN is mirrored by the loader as a 1320 problem (hasReturn), where the analyzer used to stop at an earlier run-time certainty and never say so.

From f2638b466d7cf2bad11e7f8c2a1d9b2c8f91a04e Mon Sep 17 00:00:00 2001 From: kr9ly Date: Thu, 17 Sep 2026 00:59:21 +0900 Subject: [PATCH 104/125] MySQL's own test corpus replays against mysqld and the analyzer side by side: check/mysql/internal/analyze's corpus probe (TestCorpusReplay, behind -corpus-run or $SQLSHAPE_CORPUS=1: five minutes on eight cores), the counterpart of PostgreSQL's regress probe. Each of the 1,281 .test files with SQL in it runs on a mysqld of its own (mysqltest.StartOwn, new: a private server even under Main, since the corpus creates and drops databases by name and changes accounts and global variables), connected to a fresh `test` database over one connection so SET and USE hold; after a statement that may have changed the schema the analyzer's schema is rebuilt from the server's SHOW CREATE (dump.Read, on a second connection with lock_wait_timeout 3 so a held metadata lock cannot hang it) under the session's sql_mode. A SELECT's columns are compared by name, type family and nullability, an error by number; a failure the data decides (a constraint, a conversion, a subquery's row count) is matched against the predicted violations instead. Not judged: statement kinds the analyzer does not read, references into information_schema / performance_schema / mysql / sys, statements touching a TEMPORARY TABLE (absent from SHOW CREATE), tables of another database, no-database-selected states, SHUTDOWN / RESTART / KILL, a file past its three-minute budget. Disagreements are classed LENIENT / STRICT / CODE / DIFF / RUNTIME / SCHEMA (the SHOW CREATE round trip the loader could not read) / PANIC (the analyzer crashing, recovered per statement), keyed by file, class and a hash of the text, and gated against testdata/corpus_baseline.txt (-corpus-update rewrites it). The first full run: 44,342 statements agree, 5,871 disagree (4,605 distinct, the baseline); the top classes are in the report and NOTES. Two analyzer crashes it found are fixed: a routine variable of the same name shadowed the column an INSERT column list or an UPDATE SET target in a body named, and the nil column was dereferenced -- both now resolve against the target table, 1054 when it has no such column. CHANGELOG [2.0.0]; design.md records the corpus as the third oracle beside the facts and failure probes.

A window function's integer widens through the window's temporary table (sql_tmp_table.cc's create_tmp_field_from_item, which only an Item_sum with m_is_window_function reaches: INT / BIGINT to BIGINT, TINYINT / SMALLINT / MEDIUMINT to INT, YEAR to INT UNSIGNED, the signedness kept -- types.go's tmpTableInt, applied by classType when the call carries OVER; a plain aggregate keeps the column's type, and a ROLLUP group column widens only when the plan materializes the grouping, measured on a keyed table, so it is left alone). USER() / CURRENT_USER() / DATABASE() / SCHEMA() / CURRENT_ROLE() are utf8mb3 strings (Item_func_sysconst's constructor sets the collation, which the class's own resolve_type facts never showed). DATE'...' / TIME'...' / TIMESTAMP'...' literals are typed, with the fractional digits written, and never NULL (they were untyped, which made CAST(DATE'...' AS DOUBLE) nullable). <=> is never NULL (Item_func_equal::resolve_type), judged in the PTI_comp_op branch. Under ROLLUP only an item that reads the grouped columns turns nullable; a constant such as 1+1 keeps its own. SELECT ... INTO @var returns no columns in either position at the top level (selectInto now reads the trailing INTO too, so a body's `SELECT ... FROM t LIMIT 1 INTO v` counts as an INTO rather than a result set). INSERT INTO t VALUES () -- every row empty, with or without a column list -- inserts a row of defaults instead of 1136. The probe itself stops judging what is the file's environment rather than the statement's meaning: a statement that is not UTF-8 (the gb18030 / sjis / koi8r files), a statement after a DDL under LOCK TABLES (ALTER TABLE ... RENAME under the lock leaves the new name where the dump's connection cannot see it), a CALL whose body reads a system schema or a temporary table (the corpus's own p_verify_reprepare_count), a db.routine() call (1305 of another database), and a column name the connection's character set rewrote (non-BMP characters to '?', or bytes of a single-byte SET NAMES). Docs (en / ja): the widening and the never-NULL results under the Go type table, SELECT ... INTO @var and VALUES () under statements without a result set. CHANGELOG [2.0.0]. NOTES: the third round's targets (1416 on geometry, the literal-decided 1292 / 1264 / 1690, 1193's variable list, the column-name spellings) and the ceiling (plan-dependent temporary-table widening, literal max_length).

VALUES, UPDATE ... SET, ON DUPLICATE KEY UPDATE or REPLACE, in strict mode and outside IGNORE, at the top level (a body's own run-time failures stay its raised violations): an integer out of its range, a real rounded half to even or a decimal half away first (1264), a string holding no number (1366) or followed by other text (1265); a YEAR outside 0 / 1-99 / 1901-2155 (1264); a DECIMAL(M,D) with more than M-D integer digits once rounded to D places, a negative value into UNSIGNED, a FLOAT past FLT_MAX (1264); a DATE / DATETIME / TIMESTAMP string the ported str_to_datetime rejects under the sql_mode's NO_ZERO_DATE / NO_ZERO_IN_DATE / ALLOW_INVALID_DATES, a number number_to_datetime rejects, a TIMESTAMP outside 1970-01-01 00:00:01 .. 2038-01-19 03:14:07 UTC (exact with a displacement written, otherwise only beyond a day's margin), a TIME str_to_time / number_to_time rejects or past 838 hours (1292); a string longer than a CHAR / VARCHAR / BINARY / VARBINARY (n) once trailing spaces are dropped (1406); an ENUM member that does not exist and is not a member's index, a SET list with an unknown member (1265); a number or a string into any spatial column (1416). STRICT_TRANS_TABLES alone is strict for a nontransactional table only on the first row (strictFor, measured on MyISAM). TestLiteralStoreServer pins 144 stores against mysqld, TestLiteralStore the checker's side and the non-strict schema. Found by the corpus probe, whose baseline falls 3,863 -> 3,619; three harness faults of its own fixed on the way: the session's sql_mode was left out of the schema header when empty (SET sql_mode = '' then judged as the default, 97 false 1292s), the dump connection read the dictionary from a stale snapshot when a file set autocommit off globally (locking_readonly_db's 1146s), and a CALL whose body runs DDL did not dirty the schema (a body that creates a TEMPORARY table is now not judged either).

GEOMETRYCOLLECTION) as the typed's name when a constructor, a typed reader or a constant fixes it, and judges with it what the server does: ST_GeomFromText and the typed variants over a constant WKT parse it as spatial.cc's create_from_wkt / Gis_*::init_from_wkt do (a malformed text, a LINESTRING of one point, a ring of fewer than four points or not closed, a MULTIPOINT mixing its bracket styles or empty, an empty MULTIPOINT: 3037; another type than the typed variant's: 3516; GEOMCOLLECTION is a function name, not a WKT word), ST_GeomFromWKB and its variants over a constant WKB (a hex literal, an UNHEX of a constant) read it as create_from_wkb does, either byte order per header, trailing bytes refused (3037; a geometry value given to them is 3037 too, measured), a constant SRID outside 0 .. 4294967295 is 1690; the constructors LINESTRING / POLYGON / MULTI* refuse a constant argument of another type (1210), LINESTRING of one constant (3037) and a ring of POINT constants with fewer than four points or not closed (3037), while a column argument is left alone (val_str runs per row: polygon(t.a) over an empty table runs, measured); a class whose resolve_type calls reject_geometry_args (the catalog's fact: the arithmetic and bit operators, the numeric functions, BETWEEN) given a value known to be a geometry is 1210, except the comparisons, which accept two geometries (measured, against the Item_bool_func2 fact); and a value stored into a spatial column must be the internal format of the column's type -- a number or a string literal never is, a hex / UNHEX constant is read as Field_geom::store_internal's is_well_formed does (a 4-byte SRID, a little-endian well-formed WKB of the column's type, the MULTI* types under GEOMETRYCOLLECTION, no trailing bytes), a constant of another type fails on every execution (1416, whatever the sql_mode and under IGNORE, so geometryStore runs outside storeChecks) and a nullable expression of another type on every non-NULL value: the violation 1416, keyed "1416" the way 1442 is, which mysql.WrapError now keys too. TestGeometryServer pins 120 statements against mysqld (three of the checker's first guesses corrected by it: GEOMCOLLECTION, 3516, the accepted comparison), TestGeometry the types carried and the predicted violation. The oracle's and the probe's type keys fold every spatial name into geometry, which is all the wire says. A prefix key is violable (the round's first half), so the MySQL vet fixture's expect line over tenant_notes_tenant_body no longer wants the "no expansion can violate it" diagnostic.

Where the failure lands follows the measured evaluation: a term the optimizer folds before reading rows -- a WHERE / HAVING / ON conjunct, a comparison or BETWEEN against a keyed column (the range optimizer), IN and LIKE always, a select item without a FROM, a derived table's or CTE's, INSERT ... VALUES -- is the statement's error; an expression that runs per row -- a select item over a FROM, an UPDATE's SET, ON DUPLICATE KEY UPDATE, a comparison against an unindexed column or an aggregate, RANDOM_BYTES anywhere -- is the violation 1690, keyed "1690" the way 1416 is (mysql.WrapError keys it too), and a query over no rows does not fail. What the server never evaluates is left alone: the operands after a constant that decides an AND / OR (a NULL decides an AND only in a condition; a nested AND / OR and a subquery are still processed there), the branch a constant IF / CASE / COALESCE / IFNULL condition does not take, the IN list after a constant match, x IS NULL over a never-NULL x, GROUP BY and ORDER BY items, an EXISTS's select list, LIMIT 0, a constant false WHERE without a FROM; a body is not judged. TestConstantFoldServer pins 240 statements against mysqld (the server corrected six first guesses: DEGREES multiplies by 180/pi, the unsigned cast's range is the longlong one, RANDOM_BYTES rounds its argument and is never folded, an unindexed comparison runs per row, ROUND rounds its places, a subquery's constant select item inherits the per-row position), TestConstantFold the checker's side. Name resolution: an unqualified name in a block's own GROUP BY / ORDER BY / HAVING expression resolves against the select list first (an aliased item wins over an unaliased column of the name, two different items are 1052; a table column shadows an alias in a bare GROUP BY as before), a nested query placed in an enclosing block's select list, GROUP BY, HAVING or ORDER BY sees that block's aliases (not one in its WHERE or ON): the ones declared before it -- a later one is 1247 "forward reference in item list" -- and an alias of an aggregate only from the nested query's own HAVING and never from a GROUP BY placement (1247 "reference to group function"), an alias of a window function 3594 (analyze.go's lookup / outerItem / lookupItem, a per-block list stack keyed by scope.tag replacing inHaving). HAVING never consults the block's own tables but does read an enclosing block's (fullgroup.go's outerHas; two of them are 1052), an aggregate in GROUP BY is 1056 when it is a select item as written, 1056 '???' through an alias, 1111 otherwise, GROUPING 1056. `_rowid` names a base table's first key after the server's ordering when it is unique over one NOT NULL integer column (relation.rowid), for a qualified reference or a single-table level. INSERT ... SELECT ... ON DUPLICATE KEY UPDATE resolves against the target and the SELECT's tables -- with the join's merged columns, the target last -- unless the SELECT is grouped or aggregated; VALUES(c) is the target's column alone and NULL outside the clause. TestNameResolutionServer pins 130 statements against mysqld, TestNameResolution the checker's side.

A string +// operand makes the operator a DOUBLE one (my_strtod: 'abc' is 0), a decimal one a +// DECIMAL one (never judged: my_decimal's overflow rule is not modeled); +// - DIV over non-integers divides as decimals and the truncated quotient must fit +// (either operand unsigned: BIGINT UNSIGNED); +// - CAST(f AS SIGNED / UNSIGNED) of a DOUBLE a function or operator computed fails when +// it does not fit (llrint_with_overflow_check), naming the inner expression; a DOUBLE +// literal is clamped instead (Item_float::val_int), as a decimal or a string is; +// - the message spells the expression as Item::print does: `(a + b)`, `-(x)`, +// `pow(2,1024)`, `cast(x as unsigned)`. +// +// Where the failure lands follows how the server evaluates (measured): +// +// - in a WHERE / HAVING / ON, the optimizer folds the constant before any row is read: +// the statement fails whatever the data, and so does a constant select item of a +// query without a FROM (or FROM DUAL), a derived table's or CTE's, an INSERT ... +// VALUES value, a SET. The checker raises the error; +// - in a select item of a query with a FROM, an UPDATE's SET, an ON DUPLICATE KEY UPDATE +// assignment, the expression runs per row: no row, no failure. The checker lists the +// violation 1690 (keyed "1690" the way 1416 is) instead of failing the statement; +// - AND / OR stop at the first constant that decides them (a false or, in a condition, +// a NULL for AND; a true for OR): the constants after it are never evaluated, though +// a nested AND / OR inside a condition still is. IF / CASE / COALESCE / IFNULL evaluate +// only the branch a constant condition picks, `c IN (list)` with a constant c stops at +// the first match, `x IS NULL` over a never-NULL x is folded to false without +// evaluating x (Item_func_isnull::fix_fields). GROUP BY and ORDER BY drop constant +// items unevaluated; so does EXISTS with its select list; +// - a trigger's or routine's body is not judged (a body's run-time failures are its +// raised violations, and the body walk has no row context). +// +// Ceilings: a comparison whose other side is an aggregate over no rows (NULL) skips the +// constant; `IN (SELECT c FROM t)` folds c into the

TestConvertServer pins some 200 statements against mysqld across four modes (strict, non-strict, NO_ZERO_IN_DATE off, ALLOW_INVALID_DATES; the server corrected three first guesses: BETWEEN converts per row, a YEAR message spells the value, the store's displaced-zero message is the conversion's own), TestConvert the checker's side. Baseline 3,050 -> 2,985 (hits 3,589 -> 3,521; RUNTIME 1292 82 -> 25).

USING's variables, create_user with the whole identification family, ANALYZE TABLE with UPDATE HISTOGRAM, SHOW COLUMNS / KEYS, EXPLAIN's FORMAT=); hooks_ddl.go appends name_list (KEY (a, b) and RANGE / LIST COLUMNS partitioning) and reads ternary_option's 0 / 1 as the server's switch does (anything else stays its syntax error); hooks_dml.go folds INSERT / REPLACE ... SET to the PT_insert the VALUES form builds (the SET pairs as the one row), db.t.* to Item_asterisk, JSON_ARRAYAGG / JSON_OBJECTAGG to Item_sum_json_array / _object, and JSON_TABLE's typed PATH column. A partition naming its own subpartitions explicitly is modeled rather than refused: Partition.Subs carries the names, partitionDef reads them (an option other than ENGINE stays a problem), migrate renders them back in ADD PARTITION / REORGANIZE / the whole rewrite (TestProbeExplicitSubpartitions pins the DDL against mysqld, a renamed subpartition included) and diff compares them; the per-partition MAX_ROWS / DATA DIRECTORY / TABLESPACE options and HASH's explicit partition list stay the documented ceiling. Two analyzer faults the newly loading schemas exposed, both pinned against mysqld: an unaliased select item in parentheses is named by its source text, parentheses and inner spacing included, while a column, string, numeric or NULL literal keeps its own token (TestItemNameServer); and Item_sum_json_array / _object were not in the catalog, so ONLY_FULL_GROUP_BY treated JSON_ARRAYAGG(c) as a nonaggregated column (a false 1140) -- toolchain.go now lists the hook-built classes for the catalog generation, which also picks up Item_func_in and the richer Item_lead_lag facts (the full parsegen regeneration is refused for now: the current action reader is behind the committed shapes.go / views.go). Baseline 2,985 -> 2,803 (hits 3,521 -> 3,306; unsupported construct 186 -> 0, PARTITION definitions 57 -> 12). Docs (en / ja): the migrations comparison names explicit SUBPARTITION lists; CHANGELOG's partition bullet too.

A merged view relation carries the flags sql_resolver.cc computes when it merges (viewWritability, over the FROM leaves of the view's own query: updatable when any leaf is, insertable when all are, neither under an outer join, a merged view leaf flattened into its own leaves), and the three writes follow them, each rule pinned against mysqld (TestViewWriteServer, some 90 statements). An INSERT / REPLACE lands on the base table with the base table's own violations (1062 and the rest) plus the view's own: WITH CHECK OPTION is the 1369 the insert may hit -- an underlying view's option enforced under a plain outer one too (chainHasCheckOption), still naming the view written through -- and a base column with no default the statement leaves unassigned is the view's 1423, not the table's 1364 (keyed by the view's name, mysql.WrapError reading it back the same way; the corpus judge counts 1423 among the runtime codes). The refusals in the server's own order: a non-insertable view 1471, REPLACE into a join view 1395, a join view without a column list 1394, the fields resolved against the view (1054, 1136; a derived one among them -- listed, or every view column when no list is given -- its own 1348, a COLLATE wrapper transparent as field_for_view_update is), a derived column outside the fields or one base column behind two view columns 1471, the fields of a join view kept to one base table (1393, the ON DUPLICATE KEY UPDATE assignments included), and a view whose own body re-reads the target base table in a subquery 1471 (viewBodyRereads). An UPDATE needs the updatable flag (1288); an assigned expression of the view's select list is 1348, a column of a materialized leaf inside an updatable view the view's 1288 (Column.matLeaf), a SET spanning two base tables of a join view 1393, and its Writes now cover view targets (writeFacts takes the landing table). A DELETE takes any updatable single-leaf view -- a view of only expressions included, deleteTarget resolving the base through viewWritability -- with more than one leaf 1395, anything else (multiDelete's blanket view-1288 corrected, a CTE target kept) 1288. A subquery reading the very view a single-table statement writes is the target itself (1093, write.targetViews), where the multi-table UPDATE form stays the 1443 the server spells there. Baseline 2,803 -> 2,788; the judged corpus grows instead: not judged (analyzer limit) 671 -> 261, agree (write) 21,789 -> 22,025, agree (predicted failure) 655 -> 756, STRICT 139 -> 128, CODE 139 -> 123. Docs (en / ja): the views section carries the write rules, the pinned discharge drops its "UPDATE only" gap; CHANGELOG's view bullet.

A new generated table (parsegen -sysvars reading sql/sys_vars.cc into catalog/sysvars.go: 448 variables, scope 's'/'g'/'b'; NOT_VISIBLE settings left out, a Sys_var_deprecated_alias taking its base's scope, the preprocessor walked under a stock release Linux build's defined set so a debug-only variable never enters) lets expr.go judge PTI_get_system_variable as the server does: @@session.x (@@local.x the same) of a GLOBAL-only variable and @@global.x of a SESSION-only one are the statement's 1238 wherever the read sits -- a dead branch, a subquery -- while an unqualified @@x never scope-fails and a name outside the table (a plugin's or component's variable, every @@prefix.name read) is not judged. TestSysVarScopeServer pins all 448 entries against mysqld read by read, TestSysVarPlacementServer the placements. A function call argument carrying an alias (f(x AS a), the loadable function syntax) is refused in the server's own order, before the argument is resolved (funcCallPartsAlias): a native function checks its count first (1582, whose message spells the name as written -- the previous ToUpper corrected against the server), then the alias is 1583 with the name lowercased; any other name, a stored function or one that does not exist alike, is 1584 before the function is looked up (the corpus's CODE 1584->1305 hits). A function the catalog marks internal (INTERNAL_TABLE_ROWS and the rest of the data dictionary's own) is 3566 before either check. TestFunctionAliasServer pins the order and each message. One analyzer fault the round exposed: a parenthesized query expression as a WITH statement's body -- WITH cte AS (...) (SELECT * FROM cte) -- lost the WITH clause's CTEs (bodyScope's PT_query_expression arm passed sc.outer; it now passes the scope carrying them, whose relations are still empty there). Baseline 2,788 -> 2,660 (hits 3,296 -> 3,170; LENIENT 1238 49 -> 4, all plugin or component variables, LENIENT 1583 42 -> 0, CODE 1584->1305 / 1583->1305 / 3566->1582 all 0; the two time-dependent max_statement_time 3024 lines left with them).

STR_TO_DATE is a port of the server's extract_date_time (strtodate.go): fix_from_format's result type, the specifiers with the en_US names, the %V/%v weeks with their %X/%x years over calc_daynr / get_date_from_daynr, the %r / %T sub-parses whose failure says "time", check_date under the session's zero-date flags, date_should_be_null's refusal of any zero part under NO_ZERO_DATE, and a parsed value's non-space tail as the 1292 truncation, spelt with the format's own type word. A valid UNHEX carries its decoded bytes, so BIN_TO_UUID(UNHEX(...)) judges the inner length. A second family is refused at resolution, wherever the expression sits and rows or none (wrongArguments, measured): NAME_CONST takes two literals -- one unary minus or a COLLATE wrapper is fine, a folded 1+1, TRUE or a temporal literal is not (1210), and a NULL name is the reserved syntax's 1382; LIKE's ESCAPE takes a constant of at most one character, where the server's constant is const_for_execution -- a scalar subquery, a constant expression and an introducer'd literal are left to the execution, only a column outside any subquery is refused (the corpus corrected the first, narrower guess, twelve false errors among ESCAPE subqueries, HAVING aliases naming plain columns and a routine parameter in AGAINST); NTILE takes a positive count and NTH_VALUE a positive integer position; MATCH takes real columns of one relation (a select alias over an aggregate is 1210, one naming a plain column resolves as that column and passes; a derived table's columns pass) with a constant AGAINST. Baseline 2,660 -> 2,580 (hits 3,170 -> 3,090; LENIENT 1411 54 -> 0 but for the value-dependent rest, the judged 1210s gone; the two time-dependent max_statement_time 3024 lines returned with the timing). TestFuncValServer pins some 140 statements across four sql_mode groups, TestFuncValPerRowServer the per-row placements, TestFuncVal the checker's side; probe.golden's NAME_CONST(col, col) rows move to rejected-by-both.

The changelog loses what 1.2.0 never saw -- the MySQL adversarial-rounds bullet whole (max_sp_recursion_depth moved to the server-declaration bullet, the rest is docs/mysql.md's), the probes' found-and-fixed narration, the round framing -- folds the three per-round value-failure bullets into two, and gains a Fixed section for the one behaviour 1.2.0 had wrong: a subquery in a join's ON clause reading a joined table's column, recorded as a pre-run value. The corpus honesty: README (en / ja) and docs/mysql.md's "What the checker embeds" (en / ja) now say the 137,000-statement mysql-test replay leaves 2,580 knowing disagreements, pinned one by one in corpus_baseline.txt, a new one failing the build.

The /v2/ in the module paths silently defeated the coverpkg exclusion (-e /check/postgres/catalog/gen matched nothing), so the patterns name path segments now (/catalog/gen, /internal/parsegen -- MySQL's generator joins PostgreSQL's, its cmd was already out), and the data tables parsegen writes from the server source (mysqlast/views.go, mysqlparse's shapes.go / kinds.go, the catalog's functions.go / sysvars.go) drop from the profile beside pg_query.pb.go, the same accounting the protobuf accessors already had. The 90% gate stands: measured on the deterministic suite with pg_dump and mysqld present, the tree sits at 90.8% after this accounting, 81.9% before it.

both dialects' implementations go with it, as does check/postgres/dialect's NamedOf, orphaned since Type carried its own canonical name. The `// sqlshape: type` directive on a schema that is not PostgreSQL's no longer claims a PostgreSQL type is missing: it says the dialect has no named types to bind to (typebind.go, the message a MySQL user actually needs). And the promises that held only by inspection now hold by test: an obligation declared above a MySQL CREATE VIEW binds the view's readers (discharged by a pinned read or refused with the view's own message, an unknown column a problem under the view's name; a write through the view is the base table's, judged so on both dialects -- measured on PostgreSQL, pinned here), and vet runs a MySQL schema in-process at last (testdata/schema-mysql.sql: the view obligation and the type directive in mysqlvet, the -strict advisories -- ENGINE=MyISAM enforcing nothing, a CHECK declared NOT ENFORCED -- in mysqlstrict).

The corpus grows by what the fix uncovered: 14 RLIKE / REGEXP statements now load and their run-time regexp errors (3685 / 3687 / 3696 / 3995, a 3141) join the baseline as the knowing LENIENT disagreements they are -- 2,594 now, the number told in README (en / ja) and docs/mysql.md (en / ja); the flapping max_statement_time entries (LENIENT 3024, a timing the machine decides) stay pinned as they were. The vet fixture also pins what a MySQL statement's refusals look like to a user: a construct the AST layer does not fold (CAST ... AT TIME ZONE) is reported with the statement's own text quoted, and a syntax error carries MySQL's own 1064 at the offending token. Still refused and left for its own decision: INSERT ...

The TEXT and BLOB families were typed crosswise: PT_blob_type's text-or-blob call read "has a charset" as TEXT, and the grammar passes my_charset_bin for the BLOB family and nothing for a bare TEXT variant -- so TINYTEXT loaded as tinyblob, TINYBLOB as tinytext, MEDIUM and LONG the same, LONG VARCHAR as mediumblob. The discriminator is now the charset's value, measured against SHOW CREATE on 8.4 for every spelling (TestBlobTextTypes): a TEXT variant declared CHARACTER SET binary degrades to the blob as the server stores it, TINYTEXT BINARY keeps the text with the binary collation, and 61 corpus baseline entries -- string->binary and binary->string DIFFs that were this bug pinned as knowing disagreements -- dissolve (2,534 now, the number told in README and docs/mysql.md, en / ja). And a FOREIGN KEY whose reference list is missing or does not match its column count loaded silently, with two fallbacks (violations.go, the dialect contract) pretending a bare REFERENCES names the parent's primary key; the server refuses the definition at CREATE (1239 "Key reference and table reference don't match", measured -- the bare form too), so the loader now does the same and both fallbacks go. Dead code cut where the digging found it: analyze's literalText (superseded by constText, its own call sites' comment says so), scope's findCTE wrapper, catalog's OperatorByOID with the opByOID index nothing read. And PL/pgSQL's RETURN of a plain variable -- the retvarno path beside the tested expression form -- is pinned in TestAnalyzePLpgSQL: refused in a void, SETOF or trigger function with the server's words, passed for a matching scalar.

INSERT ... VALUES (...) AS new [(names)] (8.0.19) is read instead of refused: the fold the shape reader could not follow joins hooks_dml.go's hand-written ones, and ON DUPLICATE KEY UPDATE sees the inserted columns -- the insert's own fields, not the whole table, renamed positionally by the name list -- beside the target, every rule measured on 8.4 and pinned in TestAnalyze / TestOracle: a column outside the insert's list is 1054, the old names disappear under a name list, a name list of the wrong count is 1353, a duplicate name in it 1060, an alias colliding with the target 1066, an unqualified name both sides carry 1052, VALUES(c) stays usable beside the alias, and the SET form takes the alias too (docs/mysql.md's name-resolution section tells it, en / ja). The corpus probe stops judging what the machine's speed decides: a statement the server answers with 3024 or 1317 (max_execution_time exceeded, query interrupted) is counted "not judged (timing)" -- the max_statement_time entries flapped in and out of the baseline run to run, and nine more of the same kind hid elsewhere in it; all leave, the row alias's newly-judged statements settle, and the baseline stands at 2,525 (told in README and docs/mysql.md, en / ja). And checks.md (en / ja) now states the consequence the obligation code always had: a write through an updatable view is the base table's write, so an obligation declared on a view binds its readers only -- a rule that must hold for the writes belongs on the base table.
