feat(migration): fork-aware functions, clearer BUSYKEY error, scroll-to-bottom - #378
Conversation
…to-bottom Four migration UX/correctness fixes: 1. Functions are only migrated between the same engine. When source and target are different forks (Valkey vs Redis), the RedisShake config now blocks the FUNCTION command ([filter] block_command=["function"]) so key data still migrates instead of aborting on FUNCTION LOAD (function libraries use engine-specific globals like Valkey's 'server'). 2. Cross-fork migrations surface a compatibility warning explaining that functions won't be carried over. 3. A failed migration caused by a non-empty target (BUSYKEY) now reports an actionable message telling the user to enable "Flush target before migration", instead of a bare "exited with code N". 4. Starting validation scrolls to the bottom of the page (where the validation panel and its controls are) instead of the top. Adds unit coverage for the toml filter, the cross-fork warning, and the execution wiring. API + web typecheck clean; 73 migration unit tests pass.

…Bugbot) The bottom sentinel sat below the Past Analyses history block, so scrolling to the absolute page bottom overshot the validation panel and landed on past analyses when history was present. Scroll the validation panel itself into view (block: 'end') so its controls are shown without overshooting.

Automated review of the fork-aware functions / BUSYKEY changes. 10 findings inline, most severe first; three are marked non-blocking.
The headline issue is that the block_command literal does not match how RedisShake v4.6.0 names function entries, so the filter never fires.
|
Review notes — three things, the first one is a blocker. 1.
|
…inistic BUSYKEY, gated warning
Blockers:
- RedisShake block_command must use uppercased, container-expanded command
names (FUNCTION-LOAD/RESTORE/DELETE/FLUSH); the lowercase "function" literal
never matched, so cross-fork function filtering was a silent no-op.
- Classify RedisShake failures on 'close', not 'exit': 'exit' can fire before
the stdio pipes drain and the fatal BUSYKEY line is written last, making the
actionable message intermittent. Add per-stream carry-over buffers so a line
(and tokens like BUSYKEY) never split across chunks.
Correctness/UX:
- Direction-aware exclusion via shared shouldExcludeFunctions() (Valkey->Redis
only; Redis libraries load fine on Valkey). Used by both the compatibility
report and the executor so they can't diverge.
- Gate the "functions not migrated" warning on the source actually having
function libraries (FUNCTION LIST) so a clean instance keeps its no-issues
report; correct the warning text.
- Surface the exclusion in job.logs; compute it inside the redis_shake branch
so command mode no longer logs a false lead.
Cleanup:
- Structured classifyRedisShakeFailure() in log-parser.ts ({ code, message },
exit code appended) instead of a hard-coded frontend label in the service.
- toml builders take an options object to stop swappable positional booleans.
- Braces + explicit boolean checks per repo coding standards; fix two
pre-existing lint errors in touched files.
Tests: corrected the function-warning cases, added classifyRedisShakeFailure
coverage, and moved all builder calls to the options object.
… log cap (Bugbot) The functions-exclusion notice was pushed onto job.logs before RedisShake starts, so the 500-line ring buffer evicted it once progress output filled the cap — a user who skipped analysis could see a completed run and never learn functions were omitted. Record it on a dedicated job.notices array that the log cap never trims, and prepend notices to the logs returned by getExecution so it always reaches the viewer.

Code reviewBaseline verified before reviewing: all 12 migration suites (173 tests) pass on the PR head, and One blocker, seven follow-ups. Blocker: the durable exclusion notice never reaches the user

monitor/apps/api/src/migration/migration.service.ts Lines 407 to 415 in 92d7c32 Items 1, 2 and 7 share a shape worth naming: "couldn't determine" is being treated as "determined negative". Same pattern shows up in #380. |
Blocker — exclusion notice never reached the user: getExecution merged
job.notices into logs, which the viewer renders via logs.slice(-500) inside
an autoscrolling h-64 pane, so a long run evicted the notice client-side
(undoing the backend cap fix). Notices now travel in their own result field
and render as a persistent banner above the log pane.
FU1+FU7 — "couldn't determine" was treated as "determined negative": the
FUNCTION LIST probe swallowed ACL/cluster-routing errors as "no functions",
suppressing the warning while the executor still dropped libraries. Added a
shared probeSourceFunctions() returning present/absent/unknown; analysis and
executor both treat unknown as maybe-present and warn. Executor notice is now
gated on function presence, not fork direction alone.
FU2 — BUSYKEY misattribution: classifyRedisShakeFailure keyed off the whole
buffer, so a mid-stream non-fatal BUSYKEY masked the real fatal cause (OOM,
reset, disk). Now anchors on the fatal line (panic:/FATAL, else last non-empty).
FU3 — structured failure code was dead: wire failureCode through
MigrationExecutionResult so the web layer can key remediation off the code.
FU4 — multibyte splits: setEncoding('utf8') on redis-shake stdio so UTF-8
sequences straddling a chunk boundary aren't mangled.
FU5 — validation panel scroll: block 'end' pushed the header above the fold
for tall panels; use 'nearest' to keep the top anchored.
FU6 — function-loss was direction-gated only: scan_reader and command modes
drop functions in every direction (only sync carries them). Same-engine
migrations with functions now warn that Sync mode is required, so a clean
report can't hide silent loss.
Tests updated + added; 177 migration tests pass, tsc --noEmit clean on api and web.

Set failureCode for RedisShake process errors.
If spawn or a stdio stream emits error, Line 258 rejects and the catch block marks the job as failed without failureCode. This conflicts with the shared UNKNOWN fallback for unrecognized failures. Set job.failureCode = 'UNKNOWN' in that catch block.

Both regressions were introduced by the round-2 review fixes:
1. BUSYKEY detection missed panic stacks (log-parser.ts, High). findFatalLine
searched from the end for a bare \bPANIC\b, which matches the Go stack-dump
frames log.Panicf appends after the message ("runtime/panic.go:789",
"panic({0x…})"). A trailing frame won that carries no BUSYKEY, so
classification fell through to UNKNOWN — the exact failure the change existed
to explain. Now match only definitive markers (the `panic:` header, [PANIC],
or FATAL) and drop Go source frames (.go:<line>) before locating the line.
2. Probe errors faked function warnings (fork-compat.ts, Medium). Treating every
FUNCTION LIST throw as 'unknown' (→ warn) meant Redis < 7.0 and other engines
without the FUNCTION command — which reply "unknown command" — could never
report "No compatibility issues found". "unknown command" is now classified
'absent' (provably no functions); only indeterminate failures (ACL, routing,
connectivity) stay 'unknown'.
Added coverage: panic-with-stack-dump classification, and a fork-compat.spec for
probeSourceFunctions (present / empty-absent / unknown-command-absent / ACL- and
connection-unknown). 184 migration tests pass, tsc --noEmit clean.

Redis command renaming disabled commands FUNCTION unknown command Redis security documentation Redis Functions availability version
💡 Result:
Redis Functions were introduced in Redis 7.0 [1][2][3]. The FUNCTION command serves as a container for various subcommands, such as FUNCTION LOAD and FUNCTION DELETE [1][4][5]. Regarding command security and renaming: 1. Command Renaming: Redis allows you to rename or disable commands (by renaming them to an empty string) using the rename-command directive in the redis.conf file [6][7][8]. This requires a server restart to take effect [6]. 2. Disabling FUNCTION: While the rename-command mechanism is a global configuration feature designed to handle commands from the command table, it is generally recommended to use Access Control Lists (ACLs) instead of renaming [9][7][10]. ACLs provide a more flexible, granular, and dynamic method for restricting access to specific commands (including FUNCTION and its subcommands) without requiring server restarts [7][11]. 3. Security Best Practices: Official Redis documentation emphasizes that command renaming is a legacy approach and that ACLs are the preferred method for managing security and command restriction [7]. If you must restrict FUNCTION, you can use ACL rules (e.g., -@scripting or explicitly -function) to prevent users from executing those commands [11][10]. Renaming commands can also introduce issues with replication and persistence (AOF/RDB) if not applied consistently across all nodes in a cluster or replication setup [9][6].

FUNCTION LIST is node-local, so probing only the seed connection can miss a library that lives on another master — the compatibility warning and the executor's exclusion notice could both be wrong for a clustered source. - Add aggregateFunctionPresence(): present if any node has a library, else unknown if any node was indeterminate, else absent (single source of truth for the rule; empty -> unknown). - Analysis (migration.service): aggregate over scanClients, which already holds one connection per master (or the seed when standalone) — no new connections. - Executor (migration-execution.service): add probeSourceFunctionsClusterAware(), which for a clustered source opens a direct connection per master, probes, and aggregates; standalone still does a single seed probe. Tests: aggregateFunctionPresence rules, and a function-presence spec covering standalone, library-only-on-a-non-seed-master, all-absent, a failed-master -> unknown, and the no-masters seed fallback. 193 migration tests pass, tsc clean, eslint clean.

…ients (Bugbot) Analysis aggregated FUNCTION LIST over scanClients, but when the source is clustered yet no master clients were built (scanClients empty), aggregateFunctionPresence([]) yields 'unknown' so the functions warning always fired — and a clean seed was no longer probed. The executor's probeSourceFunctionsClusterAware already falls back to the seed in that case, so the two paths disagreed. Analysis now uses the same seed fallback.
The public half of the license-signing keypair (generated per proprietary/entitlement/.env.example) was an untracked repo-root artifact that got swept into 1ba0698 by a broad `git add -A`. Nothing reads a root .pub — the monitor embeds the public key in code by kid (proprietary/licenses/ license-signing-keys.ts) — so it was just a dangling, ambiguous artifact. Untrack it (local copy kept) and add `*.pub` next to `*.pem` so the generation step can't leave one behind again. No secret was exposed: it's the public key, and *.pem already keeps the private half out of the repo.

…assified Petar's round-3 review (all non-blocking): 1. findFatalLine markers matched a format the binary never emits. v4.6.x's log.Panicf does NOT raise a Go panic — it writes one zerolog ERR line (with its own call frames appended) then os.Exit(1). Add `\bERR\b` as the primary marker (keep panic:/[PANIC]/FATAL as defensive fallbacks), fix the doc comment, and rebuild the tests from real v4.6.1 output instead of a fabricated panic stack. 2. failureCode had no consumer (FU3). Wire the BUSYKEY remediation the field was for: on a BUSYKEY failure ExecutionPanel offers "Flush target & retry" (inline confirm — it flushes the target) that re-runs with emptyDbBeforeSync. MigrationPage's start flow is refactored into startMigrationExecution(forceEmptyDb). 3. parseNodeAddress was duplicated. Export it from function-presence.ts and use it in migration.service.ts so the IPv6 logic can't drift. Plus a real bug found by running the repro end-to-end: RedisShake colourises its output, so the fatal line arrives as `\x1b[1m\x1b[31mERR\x1b[0m …`. sanitizeLogLine only redacts secrets, so the codes reached job.logs — `\bERR\b` never matched (the `m` from `[31m` kills the word boundary) and classification fell through to UNKNOWN, so the button never showed. The `.s` assembly frame in the stack tail also slipped the `.go:`-only filter. Fix: strip ANSI (new stripAnsi) at the top of processLine so the viewer, progress parsing, and classification all see clean text; broaden the frame filter to `.go`/`.s`; add tests built from the real ANSI-laden output. Verified end-to-end against a live source/target with a key collision: BUSYKEY is classified, the remediation message and button appear, logs render clean, and flush-and-retry completes. 195 migration tests pass; tsc --noEmit and eslint clean on api and web.
The "Flush target & retry" control never consulted migrationStarting, unlike the
initial confirm dialog. After the first click it reverted to its idle form while
the POST (and the server-side target flush) was still in flight — so a second
click could start a second job that flushes again and races the first on the same
target.
Thread the page's migrationStarting down as `retryPending`: while a start/retry is
in flight the control disables and shows an in-flight spinner ("Flushing target &
retrying…"), mirroring the confirm dialog. Once the request resolves the panel
transitions to the executing phase (unmounts) or, on error, re-enables.

Round-3 review. Everything from the previous round is properly addressed — I checked the code at head, not the commit messages. The container-expanded FUNCTION-LOAD/FUNCTION-RESTORE literals, the options-object builders, 'close' instead of 'exit' (with per-stream carry-over buffers and UTF-8 decoding — further than I asked), the shared shouldExcludeFunctions, the probe-gated warning, the structured failureCode, and notices living outside the log cap all look right. The log-parser suite classifying off real ANSI-coloured v4.6.1 output is a nice touch.
One blocker and three follow-ups, inline.
Not inline (the lines aren't in this diff): step 3.5's target FLUSHALL in migration-execution.service.ts:56 runs before findRedisShakeBinary() (step 4), evictOldJobs() (step 6) and writeFileSync(tomlPath) — and evictOldJobs() throws ServiceUnavailableException when all ten slots hold non-terminal jobs. So a throw anywhere in there means the target is wiped with no migration started and nothing to repopulate it. The ordering is pre-existing, but this PR is what puts a one-click button on that path, so moving the flush to after job creation + binary/TOML resolution belongs here.

Non-blocking. The execution notice covers only half of what the analysis warns about.
This fires only when excludeFunctions is true (Valkey → Redis). But compatibility-checker.ts also warns "Functions require Sync mode to migrate" for same-engine scan/command mode — and that case gets no notice at execution time. A user who starts a Valkey → Valkey scan migration without running analysis first silently loses their function libraries, which is the same failure mode this PR closes for the cross-fork direction.
Also worth noting this probe is awaited inside startExecution, before the controller returns the job id — on a cluster source with a wedged master that's up to iovalkey's 10s connectTimeout added to the POST. Moving it into runRedisShake would keep the start call responsive; the notice would just land a beat later.
…g, notice test Address Petar's round-3 review (PR #378): - function-presence: build probe clients leak-safe (retryStrategy: () => null + disconnect() instead of quit(), constructor inside try) so an unreachable master no longer spawns an endless reconnect loop or orphans a pending job. - log-parser: match the zerolog ERR level token case-sensitively so a lowercase err= field can't shadow the real fatal BUSYKEY line and drop it to UNKNOWN. - migration-execution: run the function-presence probe fire-and-forget so the POST returns the job id before connecting to source masters; the notice lands a beat later. - migration-execution: move the target pre-flush to after binary resolution, job creation and TOML write so a throw can no longer wipe the target with nothing started; a flush failure now marks the job failed instead of leaving a permanently-pending slot. - tests: give the probe mock a real call() and drive present/absent/unknown so the notice is proven for the right reason and the absent-suppression gate is covered; add a regression test for the err= shadowing.
…Bugbot) Two regressions from the previous commit, both because the probe/flush ran in the POST path after the job was already registered: - Function notice could miss the UI: the fire-and-forget probe raced job completion, so a fast scan (or a slow/wedged cluster master) could finish with empty notices and the banner never rendered. Move the probe into runRedisShake, awaited before the process spawns, so the notice is set before the job can go terminal — the POST still returns the id without waiting on any master. - Flush failure leaked the credential TOML: with the pre-flush in the POST path, a throw marked the job failed and rethrew without unlinking job.tomlPath, so a 0o600 file holding source+target passwords lingered in tmp. Move the flush into runRedisShake's try; its finally now unlinks the TOML and finalizes the job. Both are threaded through a RedisShakePreSpawn context. Adds a regression test asserting the notice is present after the job reaches a terminal state.

…bot) The pre-spawn probe/flush awaits leave the job 'pending' with no process, so a stopExecution() in that window can only set status='cancelled' — it has nothing to kill. runRedisShake then flushed the target and spawned RedisShake anyway, dropping the cancel. Re-check job.status after each pre-spawn await and bail before the destructive flush or the spawn; the finally block finalizes the cancelled job. Adds a regression test asserting neither flushall nor spawn runs when the job is cancelled mid pre-spawn.

Approving on 08ca1a43. All four round-3 findings are addressed, and I verified each against the code rather than the commit messages.
- Probe leak —
retryStrategy: () => null+maxRetriesPerRequest: 1anddisconnect()in place ofquit(), with the constructor moved inside thetry. Applied to the pre-flush clients too, which were the worse pre-existing case. - Flush ordering — probe and flush both moved into
runRedisShake, after the job exists and the TOML is written. A flush failure now finalizes through the existing catch/finally instead of 500-ing with a wiped target and no job to show for it. ERRmatching —/(^|\\s)ERR(\\s|$)/case-sensitive, withpanic:/FATALsplit into their own case-insensitive test.- Notice test — the mock now carries
call, driven acrosspresent/absent/throw.
Nice catch on the cancel window your own restructure opened: with the probe and flush moved after the POST returns, the job sits pending with no process, so stopExecution had nothing to kill. The per-await re-checks plus the test asserting neither spawn nor flushall fires are exactly right.
Correction to my previous review: I claimed the 'absent' suppression path had zero coverage. That was wrong — it already had a test with its own inline mock. Only the 'present' path was passing for the wrong reason. Sorry for the noise.
Verified CI green, and ran src/migration/__tests__ five times locally — 199/199 each time, so the new 30ms-timer tests aren't flaky.
Two non-blocking items left, fine as follow-ups:
- Same-engine scan/command mode still gets no execution-time notice —
compatibility-checkerwarns that only Sync carries functions, but a user who skips analysis and runs Valkey → Valkey in scan mode still loses them silently. Same failure mode this PR closes for the cross-fork direction. - The two new
detailstrings use inline backticks (`server`), butVerdictSection.tsx:84rendersdetailas plain text in a<p>— they'll show as literal backticks. No other incompatibility detail does that.

Summary
Four migration correctness/UX fixes, isolated on their own branch (no Docker changes).
Changes
FUNCTIONcommand ([filter] block_command=["function"]), so key data still migrates instead of aborting onFUNCTION LOAD(function libraries use engine-specific globals like Valkey'sserver).exited with code N.Tests
Added unit coverage for the toml filter, the cross-fork warning, and the execution wiring. API + web typecheck clean; 73 migration unit tests pass.
Checklist
Note
Medium Risk
Changes migration execution (optional target FLUSHALL, RedisShake config filtering) and failure handling; behavior is heavily unit-tested but mistakes could affect live data during migrations.
Overview
Improves Valkey ↔ Redis migration around server-side function libraries and RedisShake failure UX.
Functions: Valkey→Redis runs now add a RedisShake
[filter]that blocksFUNCTION-*commands so key data still migrates. Analysis probesFUNCTION LIST(per cluster master when needed) and adds compatibility warnings—excluded on cross-fork, or “use Sync mode” when libraries exist on same-engine paths. Execution pushes durablenotices(not rolling logs) when exclusion applies and the source may have functions.Failures & run lifecycle: RedisShake logs are ANSI-stripped and line-buffered; completion waits on
closeso fatal lines (e.g. BUSYKEY) are classified intofailureCodewith actionable copy. The UI offers flush target & retry on BUSYKEY. Pre-spawn probe/target flush moved intorunRedisShakewith cancel checks so a stop during probe/flush does not still spawn or flush.Other: TOML builders take a single options object; shared
parseNodeAddress/ fork-compat helpers; validation scroll usesblock: 'nearest'.Reviewed by Cursor Bugbot for commit 08ca1a4. Bugbot is set up for automated code reviews on this repo. Configure here.
