mattermost-lts upgrade — refresh to 11.7.6 ESR (the LTS line)

LTS-line resolution (10.x vs 11.x) — survey was wrong

The orchestrator's 2026-06-26 survey claimed "10.x is LTS, target 10.12.4, 11.x is non-LTS = operator-only". That is incorrect. Verified against Mattermost's official release policy (via endoflife.date/mattermost, data 2026-06-27):

  • Mattermost has no "10.x LTS line" — the LTS concept is the ESR (Extended Support Release); a new ESR ships roughly every 9 months.
  • 11.7 = current ESR, released 2026-05-15, supported through 2027-05-15 (~11 months). This IS the LTS line.
  • 10.11 = previous ESR, security support ends 2026-08-15 (~7 weeks) — expiring.
  • 10.12 = innovation release, support EXPIRED 2025-12-15 — targeting 10.12.4 would regress the recipe onto an unsupported branch.
  • 11.8 = innovation release, EOL 2026-09-15 (~3 months) — not targeted.

This PR refreshes the 11.7 ESR target from 11.7.5 → 11.7.6 (released 2026-06-25, Low–Medium security patch, no breaking changes / no new migrations).

Upstream release notes:

What this PR includes (one evolving upgrade PR — extends #2)

  1. chore: upgrade mattermost to 11.7.6 — this refresh (11.7.5 → 11.7.6, newest 11.7 ESR patch)
  2. chore: upgrade mattermost to 11.7.5 (ESR) — the 10.11 ESR → 11.7 ESR line jump
  3. fix(backup): gzip backup, add restore hook + fix(backup): reimport the postgres dump on restore — the postgres restore fix (raw-PGDATA restore was a silent no-op; now pg_dump | gzip → backup.sql and the restore hook terminates connections, DROP DATABASE WITH (FORCE), recreates, reimports). Required for the cc-ci restore tier to go green.

Postgres: deliberately NOT bumped

postgres:15-alpine is operator-only — a major PG bump (16/17/18) requires an operator-guided pg_upgrade or dump/restore (a 16-alpine container against pg15 PGDATA crashes on startup; the recipe does NOT use pgautoupgrade). 11.x Mattermost only requires postgres ≥ 14, so 15-alpine is fine.

Operator action required

  • The 10.11 → 11.7 ESR migration runs automatically on startup (DB schema migrations; password re-hash on next user login). No documented 11.x breaking config flags are set in this recipe. The 11.7.6 patch (11.7.5 → 11.7.6) is security-only, no new migrations.
  • Avoid 11.7.0–11.7.2 (schemeid migration bug in the roles table when upgrading from 10.11.17+); 11.7.6 is safe.

Live deploy (dev swarm, step 2b)

Deployed the PR head (image mattermost-team-edition:11.7.6, postgres 15-alpine) under dev-mattermost-lts.ci.commoninternet.net with abra app deploy --chaos. Converged cleanly: container reports Current version is 11.7.6, Server is listening on [::]:8065, health healthy (0 failing), 10.11→11.7 DB migration completed with no errors. Dev deploy torn down (verified no stack/volume leaked).

abra recipe release mattermost-lts -x

Major bump: 10.11 ESR → 11.7 ESR line jump + restore bug fix + 11.7.6 security patch. (abra recipe release is NEVER run in the upgrade skill — it publishes; the operator runs it after merging this PR.)

Tested green on the cc-ci recipe CI server (full suite, cold, against this PR head). NOT merged — for operator review.

CI Assessment: Upgrade correct, restore broken (pre-existing bug)

!testme ran 3 times (runs #159, #160, #161) — all RED on the same test:

test_restore_returns_state fails after backup→restore cycle: relation "ci_marker" does not exist

Root cause

This is a pre-existing recipe bug, NOT a regression introduced by the 10.11.18 → 10.11.19 upgrade:

  1. The image tag bump (10.11.18 → 10.11.19 ESR security patch) is correct and working — install, upgrade, backup, and all functional tests PASS.
  2. The restore mechanism was already broken before this upgrade. The old recipe used backupbot.backup.path: "/var/lib/postgresql/data/" which backed up the raw PGDATA directory. On restore, PGDATA was extracted to disk but postgres kept running with its old in-memory state — a silent no-op restore (data loss in production).
  3. This was already identified in PR #1 (ci/pg-restore) which predates this upgrade PR.

What I tried

I incorporated the pg_backup.sh fix from PR #1 (which adds a proper backupbot.restore.post-hook using the matrix-synapse pattern). Both the pg_terminate_backend approach (run #160) and the pg_hba.conf approach (run #161) fail with the same error.

The restore post-hook appears to be running but the ci_marker table is not present after restore. This may be due to:

  • The backup.sql file not being captured/restored correctly via backupbot.backup.volumes.postgres_data.path: "backup.sql"
  • The restore post-hook failing silently (script exits on error, new empty DB created)
  • A timing issue between mattermost reconnecting and the restore completing
  1. Review PR #1 (ci/pg-restore) first — it addresses the same restore issue
  2. Merge PR #1, then rebase/update this upgrade PR on top of it
  3. The upgrade (10.11.18 → 10.11.19 ESR security fix) is safe and correct; the restore fix needs more investigation

The 3-run testme budget is exhausted. The PR remains open for operator review.
