fix(update): never leave daemons down or web UIs missing after an update - #253
An audit of the update and web UI install flows found five ways they leave a node in a bad state that nothing repairs later:
A failed bitsocial update install leaves the daemons it stopped down, and a retry cannot find them. A run already on the target version restarts every daemon for nothing.
Re-spawned daemons can come back on the default kubo repo or endpoint.
On macOS, a locale or timezone change hides a running daemon from update install.
A failed web UI download during a fast update silently drops that web UI.
postinstall never refreshes an existing dist/webuis.
Each fix has at least one regression test that fails on master. If you would rather handle any of these differently, close this PR; nothing here is merged.
update install stops daemons only for a real install, and never leaves them down
Before, daemons were stopped before the version lookup. Any of these ended the command with the stopped daemons down and their args lost, because a daemon deletes its state file on shutdown:
an offline registry (Failed to fetch latest version)
a failed npm install -g
a daemon that did not exit within the shutdown timeout
A run already on the target version also stopped every unsupervised daemon and then re-spawned it.
Now:
The target version is resolved, and the command returns if already on it, before any daemon is stopped. An up-to-date run prints Already on vX. Use --force to reinstall. and leaves every daemon running.
When a later daemon fails to stop, stopUnmanagedDaemons re-spawns the daemons it already stopped, then rethrows. It leaves alone the daemon that failed to stop, which may still be running.
When npm install -g fails, the stopped daemons are re-spawned on the currently installed version, with a warning, before the command exits 1.
Re-spawned daemons keep their cwd and kubo env vars
The daemon now records its cwd and the IPFS_PATH, KUBO_RPC_URL and IPFS_GATEWAY_URL it was started with. These are new optional cwd and env fields in <pid>-daemon.state. update install re-spawns with them:
The recorded vars replace the updater's, and vars the daemon did not have are removed.
If the recorded directory no longer exists, the daemon starts from the updater's directory, with a warning.
State files from older daemons lack the fields and keep the old behavior.
A spawn failure, e.g. bitsocial not on PATH, now produces one warning per daemon and nothing else. Before, nothing listened for the child's 'error' event. The updater printed the warnings, then died with an uncaught Error: spawn bitsocial ENOENT stack trace and exit 1, even after a successful update. A later respawn or supervisor restart was cut off only when the event loop yielded after a failed spawn.
Stable daemon identity token on macOS/BSD
ps -o lstart= now runs with LC_ALL=C and TZ=UTC, so the token a daemon records matches the one any later CLI computes, whatever shell or timezone it runs from.
Older CLIs recorded the token in the daemon's own locale and timezone. On a mismatch, the token is compared once more in the caller's environment. A daemon started before the upgrade is therefore kept when the caller runs in the same locale and timezone as that daemon. A CLI run from another locale or timezone still prunes that daemon's state file, as master does, until the daemon is restarted and records a new token.
Linux uses /proc and is unchanged.
Fast update downloads web UIs before the swap
A web UI is now downloaded into staging when its pin changed, or when its directory is missing on disk or lacks index_backup_no_rpc.html. The daemon reads that file from every web UI directory and fails to start without it, and an interrupted run of an older postinstall can leave such a directory. This happens before anything in the current install is moved or deleted. If a download fails, fastInstallGlobal returns false, and update install falls back to npm install -g with the current install untouched. Before the swap, the directories of changed or removed entries are dropped, so a web UI removed from package.json is no longer served.
If a step fails after dist/webuis was moved into staging, for example a rename that Windows refuses with EPERM, the rollback puts dist/webuis back as it was. The dropped directories are moved to <install>.__fast_update_dropped_webuis, next to the install, instead of being deleted, and are removed after the swap. The rollback removes the downloaded web UIs and moves the dropped ones back. It also puts the current install back in place before moving node_modules into it, so a failed move of the staged install into place no longer loses node_modules. The rollback is best-effort: if one of its own renames also fails, dist/webuis can still be lost, and the npm install -g fallback, whose postinstall downloads the web UIs, reinstalls it.
postinstall decides from the pinned set, not from whether dist/webuis exists
postinstall now skips only when dist/webuis/.installed-webuis.json lists exactly the web UIs pinned in package.json. The marker is written last, after every pinned web UI was downloaded. In every other case, postinstall downloads the pinned web UIs again, without deleting what is installed first:
Each web UI is downloaded and prepared in dist/.webuis-extract, then moved to dist/.webuis-staging once complete. dist/webuis stays as it is until the new set is swapped in at the end.
A pinned web UI that cannot be downloaded keeps its installed version, matched by repo name as fast update does. The next run tries again. A directory without index_backup_no_rpc.html is never kept.
Web UIs that are no longer pinned are dropped.
If a rename during the final swap fails (e.g. EPERM or EBUSY on Windows), the previous set is put back in dist/webuis before postinstall reports the error.
If dist/webuis is missing after that, postinstall prints an error and exits 1, so the install fails instead of reporting success without web UIs. This is always the case on a fresh install, as every npm install -g is, because there is no previous set to put back.
The dist/.webuis-* work directories are excluded from the npm package (files in package.json), so leftovers of an interrupted run are never published.
An offline run in an existing checkout keeps its web UIs and exits 0:
Warning: Kept the installed seedit-html-0.6.0, because its pinned version could not be downloaded
Warning: Kept the installed plebones-html-0.1.27, because its pinned version could not be downloaded
Warning: Kept the installed 5chan-0.10.2-html, because its pinned version could not be downloaded
Installed 3 web UI(s): [ 'seedit-html-0.6.0', 'plebones-html-0.1.27', '5chan-0.10.2-html' ]
Tests
test/cli/update-install-respawn.test.ts (new): runs the real update install against a dummy daemon, with npm offline and a bitsocial shim on PATH. It checks that:
a run already on the target version leaves the daemon running and spawns nothing
an offline registry leaves the daemon running
a failed install re-spawns the daemon
the respawn uses the recorded cwd and env
a successful update with bitsocial missing from PATH prints one warning per daemon and exits 0, with no stack trace
The respawn cases use --force, which goes straight to npm install -g. With npm offline that install fails, so nothing is installed. The spawn-failure case needs the update to succeed, so it points npm at a registry on localhost that serves a fake package, which npm installs into a temporary prefix. That test also fails when only the wait for the child's 'spawn' or 'error' event is replaced by master's child.pid check: the updater exits 1 with the uncaught spawn bitsocial ENOENT.
Both used the same-version run to drive stop and respawn without npm, and that run no longer stops anything. They now run <current version> --force with npm offline (stop, failed install, respawn) and expect exit 1.
The restart-race test also asserts that a real daemon's state file records its cwd and kubo env vars.
test/update/restart-orchestration.test.ts: when a daemon fails to stop, the daemons already stopped are re-spawned.
test/common-utils/daemon-state.test.ts:
A state file written under TZ=Pacific/Kiritimati LC_ALL=it_IT.UTF-8 survives a read under TZ=UTC LC_ALL=C.
A ps token written by an older CLI is accepted when read in the same locale and timezone. This test is skipped on Linux, where no CLI ever wrote ps tokens.
pickDaemonEnv and daemonRespawnEnv
test/update/fast-update.test.ts: the failed-download test used to assert the old behavior; it now expects a fallback with the old install intact. New tests cover a changed web UI, a missing directory, an incomplete directory and a removed entry. Three rollback tests make a rename fail with EPERM after dist/webuis was moved (a downloaded web UI into place, the current install aside, the staged install into place) and check that the old install, its node_modules and its web UIs are back as they were.
test/webui/postinstall.test.ts (new): runs a copy of bin/postinstall.js against a stubbed GitHub that serves real zip files. It covers:
skipping when the install is complete, with no work directories left behind
outdated pins
retrying after a failed web UI
no directory left behind when the install step fails
keeping the installed web UIs when GitHub cannot be reached, then updating them on the next run
replacing the web UIs that downloaded while keeping the others
dropping unpinned and incomplete directories
putting the installed web UIs back when a rename during the swap fails (the preloaded stub makes the staged set's rename fail with EPERM, then the rename of the second of two kept web UIs, so the first has to be moved back)
exiting 1 with no dist/webuis when the staged set's rename fails on a fresh install, then installing normally on the next run
Each of the five fixes has at least one regression test that fails on master and passes with this change. Four of the new tests are guards that pass on master by design:
downloads a changed web UI before the swap and replaces the old version (test/update/fast-update.test.ts) covers the success path.
leaves no holding directory behind after a successful update (test/update/fast-update.test.ts) checks that the dropped web UIs are removed after the swap.
keeps a state file whose token an older CLI wrote in the caller's own timezone and locale (test/common-utils/daemon-state.test.ts) covers state files written before the upgrade.
downloads every pinned web UI and skips the download on the next run (test/webui/postinstall.test.ts) covers a fresh download and the skip on the next run.
npm run build && npm run build:test pass on every commit.
The full test suite (the vitest step of npm run test:cli) passes: 72 files, 1177 passed, 4 skipped (the same 4 as on master). An earlier full npm run test:cli run started without a marker, so the new postinstall downloaded the three web UIs from GitHub and swapped them in over the installed copies.
npm pack --dry-run no longer lists files left in dist/.webuis-*.
All commit messages pass commitlint.
Behavior changes and risks
update install exits on a registry error before it touches any daemon.
update install on the version already installed (without --force) no longer stops and re-spawns unsupervised daemons. It leaves every daemon running.
After a failed install, the stopped daemons are restarted on whatever is installed at that point. If npm left a half-replaced install, a daemon may fail to start; the warning names the situation.
The persisted <pid>-daemon.state JSON and the exported DaemonState type gain optional cwd and env fields. Older state files still work.
On macOS/BSD, newly written procStartTime values use the C locale and UTC. An older CLI, e.g. after a downgrade with a daemon still running, compares that token in its own locale and timezone. Unless its shell uses UTC and a locale that formats dates like C, it prunes the running daemon's state file, as master already does after any locale or timezone change.
A fast update with GitHub unreachable now falls back to npm install -g instead of succeeding without the changed web UI.
postinstall:
Existing checkouts have no marker yet, so their next postinstall, ci:download-web-uis or test:cli run downloads the web UIs once more. If GitHub cannot be reached, that run keeps the installed web UIs, prints a warning for each and exits 0.
postinstall exits 1 only when no web UI ends up installed: when none could be downloaded or kept, as on master in a checkout without dist/webuis, or when a failed swap leaves dist/webuis missing.
A web UI whose new pin cannot be downloaded keeps serving its previous version until a later run succeeds. Every run retries it until then.
The new directory renames have no retry for EPERM or EBUSY, which Windows can return while another process holds a file open. If a rename during the final swap fails, postinstall puts the previous set back, prints a warning and exits 0, and a later run tries again. On a fresh install there is no previous set, so postinstall exits 1 and npm install -g fails; in the npm fallback of update install, that is a failed install, which re-spawns the stopped daemons and exits 1. If a rename of the rollback also fails, dist/webuis can be left partial, or missing, in which case postinstall exits 1 as well. The previous set may then be left in dist/.webuis-old, which the next run deletes.
Log lines changed: "Web UIs directory already exists, skipping download" is now "Web UIs already downloaded, skipping download", and "Successfully downloaded N web UI(s)" is now "Installed N web UI(s)".
Not changed:
A daemon that does not exit within the 120 s shutdown timeout is left alone. It has already deleted its state file, and the error does not print its restart command.
An updater killed by Ctrl+C or SIGTERM during npm install -g still leaves the stopped daemons down; there is no signal handler.
On macOS/BSD, a daemon started before this change and checked from another locale or timezone is still pruned until it restarts, as on master.
ci-bin/download-web-uis.ts is unused and was left untouched.
Web UI downloads are verified before installed files are replaced. Failed downloads no longer leave an update partially applied, and existing pinned UIs can be retained when a download is unavailable.
Web UI installation now stages changes and restores the previous set if replacement fails. Incomplete or unpinned UIs are not retained.
Updates avoid stopping daemons when the installed version is already current. If an installation fails, stopped daemons are restarted with their saved working directory and relevant environment settings.
If stopping a daemon fails, daemons already stopped are restarted before the error is reported.
…m down [skip github-alerts]
update install stopped the unsupervised daemons before it resolved the
target version, and none of its later error exits restarted them. A
stopped daemon deletes its own state file, so its args lived only in the
updater's memory: an offline registry, a failed npm install -g or a daemon
that did not exit in time left communities offline, and a retry found
nothing to restart. A run already on the target version also stopped and
re-spawned every unsupervised daemon, though it installed nothing.
- Resolve the target version, and return if already on it, before
stopping any daemon.
- stopUnmanagedDaemons re-spawns the daemons it already stopped when a
later one fails to stop, then rethrows.
- A failed npm install -g re-spawns the stopped daemons on the currently
installed version, with a warning, before exiting with the error.
- The restart-race and systemd-aware tests used the same-version run to
drive stop and respawn without npm. They now run --force with npm
offline: stop, failed install, respawn.
… [skip github-alerts]
Outside Linux the daemon identity token is `ps -o lstart=`, which prints
in the caller's locale and timezone. A CLI run under another LC_ALL, TZ
or system timezone than the daemon read the token as a reused PID and
deleted the live daemon's state file, so update install no longer saw
the daemon and swapped files under it.
Run ps with LC_ALL=C and TZ=UTC. A token written by an older CLI, in the
daemon's own locale and timezone, is also compared in the caller's
environment, so a daemon running from before the upgrade is kept when
the caller shares that locale and timezone. Read from another locale or
timezone, such a daemon's state file is still pruned until the daemon
is restarted and records a new token.
…kip github-alerts]
The daemon state file recorded argv only, and update install re-spawned
each daemon with the updater's working directory and environment. A
daemon started with IPFS_PATH, KUBO_RPC_URL or IPFS_GATEWAY_URL, or with
a relative --pkcOptions.dataPath, came back on the default kubo repo or
endpoint when the update ran from another shell or directory, while the
update reported success.
- The daemon records its cwd and the kubo env vars it was started with
(new optional cwd/env fields in the state file; older files lack them
and keep the previous behavior).
- update install re-spawns with that cwd (falling back to its own, with
a warning, if the directory is gone) and env.
- A failed spawn, e.g. `bitsocial` not on PATH, is now a warning. Before,
nothing listened for the child's 'error' event: once the event loop
yielded after the respawn attempts, the updater died with an uncaught
`spawn bitsocial ENOENT` and exit 1, even after a successful update.
…ip github-alerts]
The fast update deleted a changed web UI's directory before it downloaded
the replacement, logged a failed download as a warning and still
reported success. The daemon then stopped serving that web UI, and later
fast updates compared package.json entries only, so nothing downloaded
it again. A web UI dropped from package.json kept its directory and was
served indefinitely.
- Download every web UI whose pin changed or whose directory is missing
into staging before anything in the current install is moved or
deleted. A failed download falls back to a full install, leaving the
current install untouched.
- Drop the directories of changed and removed entries, then move the
downloaded ones in, before the swap.
- Only a missing old dist/webuis is tolerated when carrying it over; any
other rename failure aborts the fast path.
…tence [skip github-alerts]
postinstall (also `npm run ci:download-web-uis`, which test:cli runs
first) created dist/webuis first and returned early whenever it existed,
so the directory was both its lock and its "download complete" marker.
A web UI skipped on one run (rate limit, network error) was never
retried, pins changed by a pull were never downloaded, and a directory
left without index_backup_no_rpc.html still counted as installed, which
makes daemon start fail.
- Skip the download only when dist/webuis/.installed-webuis.json lists
exactly the web UIs pinned in package.json. The marker is written last,
after every pinned web UI was installed; otherwise download again.
- Download and prepare each web UI in dist/.webuis-extract, then move it
to dist/.webuis-staging once complete. dist/webuis is left as it is
until the new set is swapped in at the end.
- A pinned web UI that cannot be downloaded keeps the complete version
already installed (matched by repo name) until a later run replaces
it. Web UIs no longer pinned are dropped. An offline run in an
existing checkout therefore keeps its web UIs and exits 0.
- Exclude the dist/.webuis-* work directories from the npm package, so
leftovers of an interrupted run are never published.
Existing checkouts have no marker yet, so their next run downloads the
web UIs once more.
The changes update Web UI installation and fast-update handling. They also change daemon state, update-install sequencing, and daemon restart recovery.
Changes: Daemon update lifecycle
Layer / File(s)
Summary
Persist daemon context and validate identity src/common-utils/daemon-state.ts, src/cli/commands/daemon.ts, test/common-utils/daemon-state.test.ts
Daemon state records the working directory and selected startup environment values. Non-Linux start-time checks use normalized locale and timezone settings, then retry with the caller’s environment when needed.
Gate installs and recover daemon restarts src/cli/commands/update/install.ts, src/update/restart-orchestration.ts, test/cli/update-install-*, test/update/restart-orchestration.test.ts
The install command checks the target version before stopping daemons. It restarts stopped daemons after install failure and uses saved working-directory and environment values when respawning. If stopping a daemon fails, previously stopped daemons are restarted. Tests cover these paths and spawn failures.
Web UI installation and updates
Layer / File(s)
Summary
Stage and replace the postinstall UI set bin/postinstall.js, package.json, test/webui/postinstall.test.ts
Postinstall skips only when its marker matches the configured UI list. It stages downloads before replacing the installed set, retains eligible existing pinned UIs after download failures, and records a complete marker only when all configured entries install.
Prepare web UIs before the fast-update swap src/update/fast-update.ts, test/update/fast-update.test.ts
Fast update reuses complete directories with matching checksum pins and stages other downloads before the install swap. It removes directories absent from the new manifest and returns false when preparation or swap operations fail.
bitsocialnet/bitsocial-cli#190 concerns supervised daemon restarts from a different npm prefix. This change adjusts unmanaged daemon respawns but does not verify the restarted binary’s version or prefix.
bitsocialnet/bitsocial-cli#191 concerns daemon compatibility after an update. This change adjusts restart behavior but does not verify the restarted daemon’s version or protocol compatibility.
bitsocialnet/bitsocial-cli#214 concerns Kubo environment overrides that differ from local configuration. This change restores recorded environment values on respawn but does not resolve configuration mismatches.

Merge Risk: Moderate · up to 76b67
Two edge-case failure paths remain. A double rename failure during postinstall rollback can leave an incomplete web UI set while the install reports success. Fast update can also keep an older web UI that postinstall retained after a failed download, instead of fetching the pinned version. Both need unusual preconditions, but both are worth fixing before merge.

The PR meets the coding requirements in [#252]. update install resolves the target before stopping daemons, avoids work for current versions, and respawns daemons after stop or install failures. Daemon state preserves cwd and the selected Kubo environment. Respawn errors become warnings. macOS/BSD process tokens use stable locale and timezone settings, with legacy-token compatibility. Fast update stages Web UIs, falls back on download failure, restores state after swap failures, and removes unpinned entries. postinstall uses the pinned-set marker, stages replacements, retains complete installed UIs when downloads fail, and rejects incomplete sets. The changed tests cover these requirements.

Restore the old Web UI directory when the swap fails
When the first rename succeeds but the staging rename or a subsequent kept-directory rename fails—for example because of a transient EPERM/EBUSY on Windows—the outer main().catch() only prints a warning and exits successfully. This leaves dist/webuis absent or incomplete while the working installation remains stranded in dist/.webuis-old; the next run then deletes that backup during cleanup. Roll back oldDir on any swap failure, or propagate the error so the package installation cannot report success without its Web UIs.

Validate web UI directories before reuse.
If postinstall retains an older version after a download failure, an unchanged manifest pin makes fast update reuse that version instead of retrying the download. An incomplete matching directory is also reused and can prevent daemon startup.

The swap moves dist/webuis to dist/.webuis-old, then moves the staged set
in and the kept web UIs over. A rename failing after the first one (e.g.
EPERM or EBUSY on Windows while a file is open) left dist/webuis missing,
or holding the new set without the kept web UIs, while postinstall exited
0. The next run deleted dist/.webuis-old, so an offline run had nothing
left to keep.
On such a failure, move the kept web UIs and the new set back out and put
the previous set back in dist/webuis before reporting the error.
…ate [skip github-alerts]
Fast update reused the directory of any web UI whose pin was unchanged.
Older postinstalls extracted straight into dist/webuis, so an interrupted
run could leave a directory without index_backup_no_rpc.html. The daemon
reads that file from every web UI directory and fails to start without
it, and the fast update carried such a directory into the new install.
Reuse only directories that have index_backup_no_rpc.html. An incomplete
one is dropped and its web UI downloaded into staging before the swap,
like a missing one.
…ip github-alerts]
The rollback of a failed swap puts the previous set back in dist/webuis.
A fresh install, as every `npm install -g` is, has no previous set, so a
failed rename of the staged set left dist/webuis missing while
postinstall warned and exited 0. The install reported success and the
daemon then failed to start on the missing directory.
After the rollback, exit 1 with an error when dist/webuis does not exist,
so the install fails instead.
…kip github-alerts]
The swap-rollback test kept a single web UI, so its failed move left
nothing to move back and the loop that moves kept web UIs back out of the
new set never ran. Keep two and fail the move of the second, so the first
has to be moved back. Without that loop the test fails, as plebones ends up
in staging instead of dist/webuis.
fca647d, 8b64f2b: postinstall swap rollback (Codex P2, CodeRabbit). If the staged set or a kept web UI cannot be moved into place (e.g. EPERM or EBUSY on Windows), the kept web UIs and the new set are moved back out and the previous set is restored before the error is reported. A fresh install, which every npm install -g is, has no previous set to restore. If dist/webuis is still missing after the rollback, postinstall now prints an error and exits 1, so the install fails instead of reporting success without web UIs. New tests inject EPERM on these renames. Each one fails without its fix.
6cdcef6: the rollback test now keeps two web UIs and fails the move of the second, so the step that moves the first one back is tested.
c1f7ae5: fast update reuses a web UI directory only if it has index_backup_no_rpc.html (CodeRabbit, fast-update.ts). The daemon cannot start without that file, so an incomplete directory is downloaded again before the swap. A new test fails without the fix.
Declined:
CodeRabbit, "verify a reused directory belongs to the pinned version": fast update runs on the global install, whose web UI directories come only from downloads for its own pins. dist/webuis is not in the package, and a reused directory's URL and sha are unchanged. Directory names do not reliably carry the version, so there is nothing sound to check.
CodeRabbit, "add which/npm to PATH in the spawn-failure test": the CLI looks for npm next to its own Node binary before it uses PATH. That covers nvm, the official installers and CI. npm's bin directory usually also holds a global bitsocial, which would defeat the test.
CI and other bots:
All checks pass, and the Claude review found no issues.
CodeRabbit's ESLint error is the repo's eslint config crash, which also happens on master. CI does not run lint.
Full npm run test:cli: 72 files, 1173 passed, 4 skipped (the same 4 as on master).

The rollback in this function's catch (below, around lines 141-163) never restores the live dist/webuis. After the web UIs are moved into staging, this PR adds more steps that can throw before the swap: fs.rm of dropped directories, the renames of downloaded web UIs into newWebuisDir, and rm of the download dir. They run alongside the existing rename(installRoot, backupDir). If one fails (for example EPERM/EBUSY on Windows), the catch moves only node_modules back and then runs fs.rm(stagingDir, ...). That deletes the old web UIs, and installRoot/dist/webuis is left missing.
fastInstallGlobal returns false and update install falls back to npm install -g. If that also fails (for example the network is down), the new respawn path restarts the stopped daemons on an install with no dist/webuis. The daemon fails to start because daemon-server.ts calls readdir(webuisDir) without a catch. This is the outcome the PR title says it prevents.
Suggested fix: before the fs.rm(stagingDir, ...), if stagingDir/dist/webuis exists and installRoot/dist/webuis does not, rename it back into place. Alternatively, move the old web UIs only immediately before the swap.
Per the PR description this gap was already known ("Not changed"). This PR makes it easier to hit, because the post-move steps are new and the respawn-after-failed-install path now relies on this rollback.

Once dist/webuis was moved into staging, a failed step before the swap
(moving a downloaded web UI into place, or moving the current install
aside) left the live install without it: the rollback deleted staging,
web UIs included. If the npm fallback of `update install` then also
failed, the stopped daemons were re-spawned on an install they cannot
start from.
The directories the new install drops are now moved to a holding
directory next to the install instead of deleted, and removed after the
swap. The rollback removes the downloaded web UIs, moves the dropped
ones back and returns dist/webuis to the current install. It also
restores the current install before moving node_modules back into it,
so a failed move of the staged install into place no longer loses
node_modules.
76b6711 (Claude inline comment on src/update/fast-update.ts): when a step fails after dist/webuis was moved into staging, the fast-update rollback now puts it back. Before, the rollback deleted staging, web UIs included.
Dropped web UI directories now go to a holding directory next to the install instead of being deleted. They are removed after the swap.
The rollback removes the downloaded web UIs, moves the dropped ones back and returns dist/webuis to the current install.
The rollback now restores the current install before moving node_modules back into it. A failed move of the staged install into place no longer loses node_modules.
Three new tests make a rename after the move fail with EPERM: a downloaded web UI into place, the install aside, and the staged install into place. They fail without the fix and pass with it.
The rollback is best-effort. If one of its own renames also fails, dist/webuis can still be lost, and the npm install -g fallback reinstalls it. The PR body says so.

Fail the install when rollback leaves a partial Web UI set.
If a kept-directory move fails and fs.rename(dstOfWebui, stagingDir) also fails, the incomplete new set can remain at dstOfWebui. This existence check then passes. The error reaches main().catch, which logs it but lets postinstall exit with status 0. A later run can delete .webuis-old, including the missing retained UIs. Track rollback failures and return a nonzero status unless the previous set was restored. Add a test that fails a rollback rename as well as the initial rename. (raw.githubusercontent.com)

Why this PR exists
An audit of the update and web UI install flows found five ways they leave a node in a bad state that nothing repairs later:
bitsocial update installleaves the daemons it stopped down, and a retry cannot find them. A run already on the target version restarts every daemon for nothing.update install.postinstallnever refreshes an existingdist/webuis.Each fix has at least one regression test that fails on master. If you would rather handle any of these differently, close this PR; nothing here is merged.
update install stops daemons only for a real install, and never leaves them down
Before, daemons were stopped before the version lookup. Any of these ended the command with the stopped daemons down and their args lost, because a daemon deletes its state file on shutdown:
Failed to fetch latest version)npm install -gA run already on the target version also stopped every unsupervised daemon and then re-spawned it.
Now:
Already on vX. Use --force to reinstall.and leaves every daemon running.stopUnmanagedDaemonsre-spawns the daemons it already stopped, then rethrows. It leaves alone the daemon that failed to stop, which may still be running.npm install -gfails, the stopped daemons are re-spawned on the currently installed version, with a warning, before the command exits 1.Re-spawned daemons keep their cwd and kubo env vars
The daemon now records its
cwdand theIPFS_PATH,KUBO_RPC_URLandIPFS_GATEWAY_URLit was started with. These are new optionalcwdandenvfields in<pid>-daemon.state.update installre-spawns with them:A spawn failure, e.g.
bitsocialnot on PATH, now produces one warning per daemon and nothing else. Before, nothing listened for the child's'error'event. The updater printed the warnings, then died with an uncaughtError: spawn bitsocial ENOENTstack trace and exit 1, even after a successful update. A later respawn or supervisor restart was cut off only when the event loop yielded after a failed spawn.Stable daemon identity token on macOS/BSD
ps -o lstart=now runs withLC_ALL=CandTZ=UTC, so the token a daemon records matches the one any later CLI computes, whatever shell or timezone it runs from.Older CLIs recorded the token in the daemon's own locale and timezone. On a mismatch, the token is compared once more in the caller's environment. A daemon started before the upgrade is therefore kept when the caller runs in the same locale and timezone as that daemon. A CLI run from another locale or timezone still prunes that daemon's state file, as master does, until the daemon is restarted and records a new token.
Linux uses /proc and is unchanged.
Fast update downloads web UIs before the swap
A web UI is now downloaded into staging when its pin changed, or when its directory is missing on disk or lacks
index_backup_no_rpc.html. The daemon reads that file from every web UI directory and fails to start without it, and an interrupted run of an older postinstall can leave such a directory. This happens before anything in the current install is moved or deleted. If a download fails,fastInstallGlobalreturns false, andupdate installfalls back tonpm install -gwith the current install untouched. Before the swap, the directories of changed or removed entries are dropped, so a web UI removed from package.json is no longer served.If a step fails after
dist/webuiswas moved into staging, for example a rename that Windows refuses with EPERM, the rollback putsdist/webuisback as it was. The dropped directories are moved to<install>.__fast_update_dropped_webuis, next to the install, instead of being deleted, and are removed after the swap. The rollback removes the downloaded web UIs and moves the dropped ones back. It also puts the current install back in place before movingnode_modulesinto it, so a failed move of the staged install into place no longer losesnode_modules. The rollback is best-effort: if one of its own renames also fails,dist/webuiscan still be lost, and thenpm install -gfallback, whose postinstall downloads the web UIs, reinstalls it.postinstall decides from the pinned set, not from whether dist/webuis exists
postinstall now skips only when
dist/webuis/.installed-webuis.jsonlists exactly the web UIs pinned in package.json. The marker is written last, after every pinned web UI was downloaded. In every other case, postinstall downloads the pinned web UIs again, without deleting what is installed first:dist/.webuis-extract, then moved todist/.webuis-stagingonce complete.dist/webuisstays as it is until the new set is swapped in at the end.index_backup_no_rpc.htmlis never kept.dist/webuisbefore postinstall reports the error.dist/webuisis missing after that, postinstall prints an error and exits 1, so the install fails instead of reporting success without web UIs. This is always the case on a fresh install, as everynpm install -gis, because there is no previous set to put back.dist/.webuis-*work directories are excluded from the npm package (filesin package.json), so leftovers of an interrupted run are never published.An offline run in an existing checkout keeps its web UIs and exits 0:

The spawn-failure case needs the update to succeed, so it points npm at a registry on localhost that serves a fake package, which npm installs into a temporary prefix.
