fix(server): updates copy the database while the server still runs when it cannot be cloned - #33058
This changes the update path, which is the most crash-critical code in T3 Code. It copies a live SQLite database while the server is still writing to it, and its correctness rests on SQLite WAL locking rules and on a POSIX lock subtlety (below). It is tested and reviewed, but it has not run on real Linux ext4 hardware, on Windows, or inside the shipped single-executable t3. Please review it as a design change, not a small fix. I'm happy to close it if you'd rather keep the offline copy.
Problem
On a filesystem that cannot clone files (Linux ext4, Windows NTFS), a service update stops the server and then copies the whole database before starting the new version, so the copy is all downtime. The reporter in #32952 has a 13.5 GB database on ext4 and sees about 3 minutes offline per update. The launcher their service runs (v0.0.46, pinned by #17490) and main both do this plain copy on ext4.
Change
When the backup cannot be cloned, the launcher now copies the main database file before it stops the server:
After the update is accepted, the launcher opens a read-only node:sqlite connection and holds a read transaction. That keeps SQLite from resetting or truncating the WAL.
It copies the resolved main file with a cp child process (in-process copyFile on Windows) while the server keeps serving.
It stops the server, copies the WAL (not -shm), closes the snapshot, and renames staging into the normal backup directory.
The existing offline backup then returns early, and restore is unchanged: on open, the copied WAL overrides any page the main-file copy caught mid-checkpoint. -shm is deliberately left out, because its backfill count would make SQLite trust those pages. Any failure (not WAL mode, copy error, WAL missing) discards staging and falls back to today's offline backup. Clone-capable filesystems (APFS, btrfs/XFS reflinks) keep their instant offline clone and are unaffected.
Other changes in apps/server/src/serviceLauncher.ts:
databaseBackupBlocker reserves 256 MiB more on the non-clone path, because the live WAL and its copy can each reach the server's 128 MiB gate while the snapshot is held.
#beginTrial does not start a trial when a stop was requested during the copy. The copy widens that window from 2 s to minutes. Restart resumes the pending update with the finished backup.
Risks — please read
A POSIX lock subtlety is load-bearing. While the snapshot is open, the launcher must never open and close the database or -shm with in-process fs. A POSIX close() drops every fcntl lock this process holds on that file, and SQLite could then delete the WAL. A probe proved the -shm case lets wal_checkpoint(TRUNCATE) succeed. The code only uses access/stat/realpath on those paths and copies in a child process. A future edit that adds an in-process read of the database in that window would silently break backups.
Windows is unverified.copyFile runs in-process there, which should be safe because Windows LockFileEx locks are per-handle, not per-process. A sharing violation falls back to the offline backup. Nobody has run it on Windows.
Writes can stall during the copy. The held read transaction blocks WAL truncation. On a write-heavy server, once the WAL passes the 128 MiB gate in nodeSqliteClient, writes wait until the copy ends. At the reporter's disk speed that is roughly 0.7 MB/s of writes for 3 minutes. That's a stall where today there is an outage. If the gate is reached, a write during shutdown may also wait out the 5 s grace and be killed; the database stays consistent.
A second process during the copy. If another process opens the database during the copy (the issue mentions the desktop's SSH launcher spawning t3 serve), our read lock still prevents WAL reset or deletion. That is reasoned from SQLite's locking rules, not tested.
Launcher killed mid-copy. The pending update is recorded before the copy, as today, but the window is now minutes. On restart, the recovery path discards the half-made staging directory and backs up offline. The new case is a live server outliving a killed launcher, which today exists for 2 s.
Pre-existing bug found during review, not changed here: for a symlinked database path, rollback restores -wal beside the symlink, while SQLite reads the one beside the resolved file. A trial's WAL can then be replayed over the restored database. Reproduction: restoreDatabaseBackup + backupDatabaseOnce derive -wal from the unresolved path. This PR's online copy resolves the path, but restore does not. I can open a separate issue or PR.
Scope and approval
Fixes#32952. No maintainer has approved this direction yet. The issue suggested VACUUM INTO / skipping free pages. We measured those first and they don't help:
A cold VACUUM INTO backup of a real 6.2 GB, 57%-free T3 database took 36.7 s vs 7.7 s for a plain copy, because it reads scattered live pages one at a time.
Packing only live pages, or compressing the backup, landed within noise of a plain copy on the same database (6.3–8.0 s). They also need SQLite file-format parsing in the launcher and break downgrades.
Copying online removes the copy from downtime on any non-cloning filesystem, regardless of free pages. The backup stays a plain SQLite file, so restore and downgrade behaviour don't change.
The issue's second suggestion already exists: Settings recommends t3 doctor when a non-incremental database holds at least 1 GiB of free pages. If you'd prefer a different direction (for example, offering the reclaim from the update flow), I'll close this.
Verification
New test, backs up a %s-mode database (online when WAL) and restores its final state, in apps/server/src/serviceLauncher.test.ts. It fails on main ("expected [] to deeply equal [ [ 'database' ] ]"), because no backup exists when the server is told to stop. The active server writes continuously until SIGTERM.
WAL mode: the main file is already in staging when the server is asked to stop. The trial sees exactly database and database-wal, which only the online path produces; the offline fallback would also copy -shm. Rollback restores every row, including the last write before stopping, and passes integrity_check.
Rollback-journal mode: falls back to the offline backup and restores correctly.
All 18 launcher tests pass. vp run check:changed passes: format, lint, knip, typecheck, tests.
Runtime transcript: the real Launcher on a 6.2 GB copy of a real T3 database, cloning reported unavailable, with the server writing every 5 ms:
0.0s server running; requests update
18.1s server told to stop after 2903 writes while serving
18.3s trial server started; backup [["database",6172803072],["database-wal",14873232]]
18.5s previous version back after rolled-back
restored: integrity ok | final write kept: true | journal wal
The server was down for about 0.2 s between stop and trial start. With today's code that gap is the whole copy (7.7 s cold for this file here; about 3 min on the reporter's host).
Correctness evidence for the snapshot argument comes from standalone scripts: 17 of 17 online-copy restores equalled the final live state with a writer running PASSIVE and TRUNCATE checkpoints during the copy, including the read-mark-0 / WAL-restart case. Another probe proved the POSIX lock hazard in risk 1.
Not checked: real ext4 or NTFS hardware, Windows, the SEA build, and a server under sustained heavy write load during a multi-minute copy.
Macroscope's review found this PR requires human approval — The update path moves database copying before server shutdown, reducing downtime but potentially stalling writes during long copies. It also introduces a new lint suppression that requires human review.

Walkthrough
The launcher attempts a WAL-mode database backup while the service runs, then completes and publishes it after stopping the service. Full-copy space estimates include 256 MiB of WAL headroom. Tests cover backup contents and rollback integrity in WAL and DELETE journal modes.
Changes: Online database backup
Layer / File(s)
Summary
WAL snapshot and backup creation apps/server/src/serviceLauncher.ts
Full-copy disk estimates include WAL headroom. The launcher copies the main database file from a read-only SQLite snapshot, then copies and syncs the WAL before publishing the backup. Setup or completion failures clean up staging and defer to the offline backup path.
Trial lifecycle and rollback validation apps/server/src/serviceLauncher.ts, apps/server/src/serviceLauncher.test.ts
The launcher completes the backup after stopping the active child and checks for a stop request before starting a trial. Tests cover backup contents and rollback integrity in WAL and DELETE journal modes. The expected full-copy space requirement is updated.

Merge Risk: Minimal · previous review d9e51
The update backup now copies the main database while the server is still running, which should shorten update downtime, and it falls back to the existing offline backup on failure. No new merge-blocking issue remains from this review. The earlier published notes on shutdown responsiveness and write pressure during very long copies remain open for the author to decide on.

Explanation
Issue #32952 requires reducing database-copy downtime during service updates. startOnlineDatabaseBackup in apps/server/src/serviceLauncher.ts holds a read transaction, copies the resolved main file before terminateChild, copies only -wal after shutdown, and publishes the staged backup. Non-WAL or failed online copies use the existing offline backup. The new test covers WAL online backup, delete-mode fallback, rollback, row preservation, and integrity_check. The issue suggestions to omit freelist pages or add a reclaim prompt are alternatives, not mandatory coding requirements.

Bound WAL growth during the online copy.
If the checkpoint worker is unavailable, sustained writes can grow the pinned WAL beyond the 256 MiB allowance. On a nearly full filesystem, the live database can run out of space before the main copy finishes and the launcher stops the server. The offline path stops writes before copying.

On CodeRabbit's outside-diff finding (writes blocked during the online copy, serviceLauncher.ts:305-313): the description is accurate, but I'm not changing the flow here.
What happens: while the snapshot is pinned, checkpoints can't get past its read mark. If the WAL reaches the backpressure ceiling or journal_size_limit, nodeSqliteClient holds new write transactions at admission. The snapshot is released only in finish, after terminateChild, so a write that hits the gate waits until the server stops. It never starts its transaction, so nothing partial is written. The command is lost the same way as one that arrives while the offline backup stops the server today.
Why not bound it: releasing the snapshot before the stop would let SQLite reset the WAL. The main-file copy would then no longer line up with the WAL copied after the stop, which is the guarantee the online copy depends on. A bounded wait that keeps the snapshot would need a new launcher↔child handshake to drain or refuse writes before the stop. That's heavier than this fix, and it only matters when a server writes past the WAL ceiling during the minutes-long copy. If maintainers want that, it can follow separately.
Comment fix: the comment overstated when the stall ends. It said writes stall "until the copy ends", but they wait until the server stops. Corrected in 75ff8b7.
verified as-is at 75ff8b71408894f287030d94ed6b9cebe50e92cc on a linux ext4 boat vm, where reflink cloning fails naturally.
i reproduced the original ordering on github/main (bcee0f5d28) in a separate worktree, then checked out the exact pr head and installed dependencies. playwright used the repo dependency and /usr/bin/google-chrome. i created a project against a real git repo and a conversation through the web app, with real codex gpt-6.1-sol turns that read README.md.
for the update itself, i ran each checkout's unmodified source launcher managing the real source server over ipc, with the vite client. ordinary vp run dev deliberately disables service management, so it cannot exercise this path. i called the authenticated server.updateServerWithProgress websocket rpc used by the client, targeting the actual published 0.1.9-nightly.20261110.4465 release. its download, preflight and trial ran for real. the main and pr verification stacks ran sequentially.
syscall evidence shows the changed behavior:
main:
10:20:49.598 server sent SIGTERM
10:20:49.842 database copy destination opened
10:20:49.894 real candidate started
result: committed
pr:
10:26:26.538 main database cp started while source server was running
10:26:26.565 source server sent SIGTERM
10:26:26.875 WAL cp started
10:26:26.890 staging renamed to published backup
10:26:26.901 real candidate started
result: committed
the captured pr backup contained exactly database and database-wal; PRAGMA integrity_check returned ok. the browser reconnected with its conversation intact, and a real codex continuation completed after the update.
i repeated the update and deliberately killed the actual candidate just after launch. the launcher recorded rolled-back / candidate-exited:SIGKILL and restarted the source server. the backup and restored databases both passed integrity checks. all nine pre-update conversation message rows matched byte for byte, with the same sha256. another real codex turn read README.md and completed after rollback.
blacksmith checks passed: the 18 launcher tests, then vp run check:changed ade473018d32003658b7d38693e083ee2e314bd8 against the actual pr merge base, including format, lint, knip, graphql, affected typechecks and 20 tests. no source changes were needed.
windows, macos, native mobile and electron clients; clone-capable filesystems; symlinked database rollback; multi-minute copies or sustained writes reaching the 128 mib wal gate. the launcher ran from source, while the candidate was the published executable. these small-database timestamps prove ordering, not large-database performance. the recording shows post-rollback provider use; the syscall transcript proves the backup ordering.
…target
SQLite keeps -wal and -shm beside the resolved database file. The online
backup copies the WAL from there, so restoring it beside the symlink lost
every commit it held.
AI-assisted; verified with the tests and tools listed above.
Manual comparison of the built CLI and real service launcher on Linux ext4, using fresh synthetic replay conversations and symlinked WAL databases. Trigger the launcher update protocol, observe HTTP availability during an identical eight-second gate at the real main-file cp entry, deliberately fail the candidate, and verify rollback preserves the conversation. The gate demonstrates ordering, not large-database copy speed.
Scope: this proves backup/shutdown ordering and rollback for the controlled synthetic case. It does not reproduce the full Settings-to-published-update flow or the reported multi-gigabyte copy duration.
AI-assisted; verified with the tests and tools listed above.
Not shown:
The reported large-database duration was not reproduced: the database was small and the main-file cp entry was deliberately gated for eight seconds.
The Settings Update server interaction and operating-system service installation were not exercised; the built launcher was started directly and received its normal update IPC request.
Successful startup of a newer published candidate was not exercised; the staged candidate deliberately failed to demonstrate rollback.
Sustained concurrent writes and checkpoint pressure during a large online copy were not exercised.

* feat(opencode): track native image job outcomes and previews (pingdotgg#34089)
OpenCode image-generation tool success acknowledges a launched background job. Keep that job pending until its native outcome arrives, retain the outcome on the original tool item, and serve size-limited image previews through existing rendering and remote file paths.
Recover outcomes after stream loss, allow later exact-path notices to add previews, and clear descendant image tasks from parent rosters on completion or transport failure. Keep older-server fallback and the pinned SDK.
Validation: check:changed passed with 147 tests; required CI passed and review findings were addressed on 62addc8. Client screenshots use controlled fixtures; no paid image generation was used.

* feat(opencode): track native shell jobs across turns
## Problem
OpenCode shell tools can return when a background command launches. T3 now keeps that command in its existing background activity UI until it exits or is stopped, retains captured output, and preserves native completion notifications and continuation turns.
## Change
The adapter scopes tracking and Stop to the owning session and its descendants. Recovery uses the experimental shell-job inventory on OpenCode 2.2.6+, with shell-list fallback on supported older servers. After a cold resume, recovered output, terminal state, and idle roster snapshots persist through the existing session event pump before another turn starts. New session-scoped activity is restricted to attached threads and uses the persisted run identity when available so it stays in the current timeline. Polling reads run outside the adapter lock, with stale results discarded after Stop, exit, or another read. Recovery and Stop retain bounded I/O. Final reads retain the output tail, including diagnostics beyond the first four pages. The SDK remains pinned to 2.0.28, and main's native goals, todo checklists, and image jobs are preserved.
## Scope and approval
Maintainer-directed implementation of native OpenCode background shell tracking from the T3 Code handoff. Scope covers shell lifecycle, output retention, recovery, ownership, and Stop using existing background activity services and rendering. The session event pump extension is needed to persist recovered activity while no turn is active. No SDK upgrade, new UI, or provider-wide infrastructure is included. The author, Yash-Singh1, is explicitly listed in the repository's [contribution-triage exemptions](https://github.com/pingdotgg/t3code/blob/main/.github/TRIAGE_EXEMPTIONS.td), verified against upstream main.
## Verification
Validation: `vp run check:changed` passes. Focused regressions cover output paging, exit codes, idle recovery, persisted run anchors, ownership, cancellation failures, and a stalled poll that must not block turn completion or Stop. Real OpenCode UI turns used MiniMax M3.1 Flash Free against isolated development state and covered launch, Details and retained output, natural completion, continuation, and explicit Stop. Cold-idle persistence and remote-server paths use protocol fixtures; native mobile was not exercised.

Warning
This changes the update path, which is the most crash-critical code in T3 Code. It copies a live SQLite database while the server is still writing to it, and its correctness rests on SQLite WAL locking rules and on a POSIX lock subtlety (below). It is tested and reviewed, but it has not run on real Linux ext4 hardware, on Windows, or inside the shipped single-executable
t3. Please review it as a design change, not a small fix. I'm happy to close it if you'd rather keep the offline copy.Problem
On a filesystem that cannot clone files (Linux ext4, Windows NTFS), a service update stops the server and then copies the whole database before starting the new version, so the copy is all downtime. The reporter in #32952 has a 13.5 GB database on ext4 and sees about 3 minutes offline per update. The launcher their service runs (
v0.0.46, pinned by #17490) andmainboth do this plain copy on ext4.Change
When the backup cannot be cloned, the launcher now copies the main database file before it stops the server:
node:sqliteconnection and holds a read transaction. That keeps SQLite from resetting or truncating the WAL.cpchild process (in-processcopyFileon Windows) while the server keeps serving.-shm), closes the snapshot, and renames staging into the normal backup directory.The existing offline backup then returns early, and restore is unchanged: on open, the copied WAL overrides any page the main-file copy caught mid-checkpoint.
-shmis deliberately left out, because its backfill count would make SQLite trust those pages. Any failure (not WAL mode, copy error, WAL missing) discards staging and falls back to today's offline backup. Clone-capable filesystems (APFS, btrfs/XFS reflinks) keep their instant offline clone and are unaffected.Other changes in
apps/server/src/serviceLauncher.ts:databaseBackupBlockerreserves 256 MiB more on the non-clone path, because the live WAL and its copy can each reach the server's 128 MiB gate while the snapshot is held.#beginTrialdoes not start a trial when a stop was requested during the copy. The copy widens that window from 2 s to minutes. Restart resumes the pending update with the finished backup.Risks — please read
-shmwith in-processfs. A POSIXclose()drops everyfcntllock this process holds on that file, and SQLite could then delete the WAL. A probe proved the-shmcase letswal_checkpoint(TRUNCATE)succeed. The code only usesaccess/stat/realpathon those paths and copies in a child process. A future edit that adds an in-process read of the database in that window would silently break backups.copyFileruns in-process there, which should be safe because WindowsLockFileExlocks are per-handle, not per-process. A sharing violation falls back to the offline backup. Nobody has run it on Windows.nodeSqliteClient, writes wait until the copy ends. At the reporter's disk speed that is roughly 0.7 MB/s of writes for 3 minutes. That's a stall where today there is an outage. If the gate is reached, a write during shutdown may also wait out the 5 s grace and be killed; the database stays consistent.t3 serve), our read lock still prevents WAL reset or deletion. That is reasoned from SQLite's locking rules, not tested.Pre-existing bug found during review, not changed here: for a symlinked database path, rollback restores
-walbeside the symlink, while SQLite reads the one beside the resolved file. A trial's WAL can then be replayed over the restored database. Reproduction:restoreDatabaseBackup+backupDatabaseOncederive-walfrom the unresolved path. This PR's online copy resolves the path, but restore does not. I can open a separate issue or PR.Scope and approval
Fixes #32952. No maintainer has approved this direction yet. The issue suggested
VACUUM INTO/ skipping free pages. We measured those first and they don't help:VACUUM INTObackup of a real 6.2 GB, 57%-free T3 database took 36.7 s vs 7.7 s for a plain copy, because it reads scattered live pages one at a time.The issue's second suggestion already exists: Settings recommends
t3 doctorwhen a non-incremental database holds at least 1 GiB of free pages. If you'd prefer a different direction (for example, offering the reclaim from the update flow), I'll close this.Verification
New test,
backs up a %s-mode database (online when WAL) and restores its final state, inapps/server/src/serviceLauncher.test.ts. It fails onmain("expected [] to deeply equal [ [ 'database' ] ]"), because no backup exists when the server is told to stop. The active server writes continuously until SIGTERM.databaseanddatabase-wal, which only the online path produces; the offline fallback would also copy-shm. Rollback restores every row, including the last write before stopping, and passesintegrity_check.All 18 launcher tests pass.
vp run check:changedpasses: format, lint, knip, typecheck, tests.Runtime transcript: the real
Launcheron a 6.2 GB copy of a real T3 database, cloning reported unavailable, with the server writing every 5 ms:The server was down for about 0.2 s between stop and trial start. With today's code that gap is the whole copy (7.7 s cold for this file here; about 3 min on the reporter's host).
Correctness evidence for the snapshot argument comes from standalone scripts: 17 of 17 online-copy restores equalled the final live state with a writer running
PASSIVEandTRUNCATEcheckpoints during the copy, including the read-mark-0 / WAL-restart case. Another probe proved the POSIX lock hazard in risk 1.Not checked: real ext4 or NTFS hardware, Windows, the SEA build, and a server under sustained heavy write load during a multi-minute copy.
