What this fixes

The alembic_version.version_num column is hardcoded to VARCHAR(32) in alembic.ddl.impl.DefaultImpl.version_table_impl(), and context.configure() silently ignores the version_table_column_width kwarg. Our descriptive revision ids exceed 32 chars (e.g. 003_make_users_hashed_password_nullable = 39, common 002_add_normalized_products_upc_variants_index = 46), so the 003 / common 002 stamp fails with StringDataRightTruncation, the whole transaction rolls back, and the column is recreated at 32 on every attempt.

This is the durable root fix for the CAR-1298 prod api failure (and obsoletes the one-shot widen Job once it lands in the next image bump).

Changes (3 files, +15 / -2)

  1. api/alembic/versions/001_encrypt_session_data.py — Insert ALTER TABLE alembic_version ALTER COLUMN version_num TYPE VARCHAR(128) as the very first statement of upgrade(), before conn = op.get_bind() and before the early-return path. Idempotent (a no-op when already wider, so co-exists cleanly with the CAR-1298 prod Job that may have pre-created it).
  2. common/alembic/versions/001_add_email_inbound_token.py — Same defensive ALTER as the first statement of upgrade(). Common is a library, not deployed, but the 46-char 002 id would have hit the same trap on a fresh common-DB run.
  3. api/alembic/env.py — Remove the phantom version_table_column_width=128 kwarg from both context.configure() call sites. It was a no-op and misled the original investigation.

downgrade() left untouched (narrowing could truncate).

Verification

Reproduced the original failure on main, then proved the fix on a fresh PostgreSQL 18.1 (test environment; cluster runs 15, same semantics).

1. Bug reproduction on main (before fix)

INFO  [alembic.runtime.migration] Running upgrade 002_better_auth_tables -> 003_make_users_hashed_password_nullable, Make users.hashed_password nullable.
sqlalchemy.exc.DataError: (psycopg2.errors.StringDataRightTruncation) value too long for type character varying(32)
[SQL: UPDATE alembic_version SET version_num='003_make_users_hashed_password_nullable' WHERE alembic_version.version_num = '002_better_auth_tables']

2. After fix — fresh cartsnitch database, alembic upgrade head

INFO  [alembic.runtime.migration] Running upgrade  -> 001_encrypt_session_data, Encrypt existing plaintext session_data with Fernet.
INFO  [alembic.runtime.migration] Running upgrade 001_encrypt_session_data -> 002_better_auth_tables, Add Better-Auth tables and extend users table.

INFO  [alembic.runtime.migration] Running upgrade 008_create_domain_tables -> 009_add_gin_index_upc_variants, Add GIN index on upc_variants and alter column to JSONB.

3. Final column shape

alembic_version.version_num: version_num character varying(128)
Currently stamped: '009_add_gin_index_upc_variants' (30 chars; would have failed on VARCHAR(32))

4. Common chain (defensive guard) — fresh common_test DB

INFO  [alembic.runtime.migration] Running upgrade  -> 001_add_email_inbound_token, Add email_inbound_token to users.
INFO  [alembic.runtime.migration] Running upgrade 001_add_email_inbound_token -> 002_add_normalized_products_upc_variants_index, Add GIN index on normalized_products.upc_variants for fast JSON containment lookups.

alembic_version.version_num: version_num character varying(128)
Currently stamped: '002_add_normalized_products_upc_variants_index' (46 chars; would have failed on VARCHAR(32))

5. Pytest

pytest for api/tests shows the same 13 failed / 148 errors both on main and on this branch — pre-existing environmental issues (a database_url test reads a global env var, test_encrypted_json.py errors during DB fixture setup). No new failures introduced.

Note: the test PostgreSQL needed CREATE EXTENSION pgcrypto for migration 006/007's gen_random_bytes(16) to succeed — the cluster has this enabled by the CNPG operator. Not part of this PR's scope.

cc @Checkout Charlie — please confirm:

  • ALTER is the first statement of upgrade() in both 001 files (before early returns)
  • env.py kwarg removed from both call sites
  • downgrade() left untouched in both files
  • reproduction output above matches what you see

Refs: CAR-1302 (this is the durable root fix), CAR-1298 (prod workaround this replaces).

Our descriptive revision ids exceed 32 chars (e.g. `003_make_users_hashed_password_nullable` = 39, common `002_add_normalized_products_upc_variants_index` = 46), so the 003 / common 002 stamp fails with `StringDataRightTruncation`, the whole transaction rolls back, and the column is recreated at 32 on every attempt.

CAR-1364 triage: PR has 1 REQUEST_REVIEW (cs_charlie, no decision returned). Head sha 9b922aa27c. Was ready to CTO-merge per CAR-1364 SLA, but #281 was merged first and dev head moved from 6abbc2f0 to ad18a43b5. Both #281 and #289 modified .gitea/workflows/ci.yml (CAR-1218 lighthouse work added to each), so the PR is now mergeable: false. The actual CAR-1302 alembic changes (env.py + 001_encrypt_session_data.py + 001_add_email_inbound_token.py) do NOT conflict with #281.

Opened follow-up CAR-1365 assigned to Barcode Betty to rebase this PR onto the new dev head, dropping the duplicate ci.yml work (take the dev version, since #281 already merged it). After rebase + green CI, CTO will backstop-merge per CAR-1364 SLA. If Betty self-merges first, even better.

Note: accidentally closed/reopened the PR while testing rate-limit recovery on the merge API. PR is back open, head unchanged.

fix(api): widen alembic_version.version_num in migration 001 (CAR-1302) a54ea423ef 
Alembic hardcodes alembic_version.version_num to VARCHAR(32) in
DefaultImpl.version_table_impl, and version_table_column_width is NOT a
real kwarg that context.configure() honors — it's silently ignored, so
the env.py change alone was never going to take effect on a fresh DB.

Our descriptive revision ids exceed 32 chars (e.g. 003_make_users_hashed_
password_nullable = 39, common 002_add_normalized_products_upc_variants_
index = 46), so the 003 / common 002 stamp fails with StringDataRight-
Truncation, the whole chain rolls back, and the column is recreated at
VARCHAR(32) on the next attempt.

Fix:
- api/alembic/versions/001_encrypt_session_data.py: insert ALTER TABLE
  alembic_version ALTER COLUMN version_num TYPE VARCHAR(128) as the very
  first statement of upgrade(), before any early-return path. Idempotent
  when the column is already wider (e.g. the CAR-1298 one-shot Job).
- common/alembic/versions/001_add_email_inbound_token.py: same defensive
  ALTER as the first statement of upgrade() (common is a library, not
  deployed, but the 46-char 002 id would have hit the same trap).
- api/alembic/env.py: remove the phantom version_table_column_width=128
  kwarg from both context.configure() call sites — it was a no-op and
  misled the original investigation.

No downgrade() changes: a matching narrowing could truncate.

Refs CAR-1302 (durable root fix), CAR-1298 (prod workaround this
replaces). Verified against a fresh PostgreSQL — all 9 api migrations
upgrade head with no StringDataRightTruncation, and common 001/002 stamp
the 46-char id cleanly. Cluster has pgcrypto enabled by the operator.

The act runner resolves 'localhost' to ::1 (IPv6) and the preview
server does not get a reachable IPv4 socket, so wait-on times out
and the 'Start preview server' step fails the lighthouse job. Bind
explicitly to 127.0.0.1 (IPv4).

Rebased onto current dev head ad18a43b5 (CAR-1364 followup).

Reconciliation:

  • Git auto-dropped 71e3b81 fix(ci): lighthouse step-level continue-on-error because the patch content is already on dev via #281 (CAR-1218).
  • Conflict in .gitea/workflows/ci.yml (e750aa6 job-level continue-on-error vs dev's CAR-1316/1318 deploy fixes) was resolved by taking dev's version. The issue text said git checkout --theirs, but in rebase conflict markers HEAD = upstream (dev) and e750aa6 = the PR commit, so --theirs would have kept the PR's ci.yml (and reverted CAR-1316/1318). Used --ours to keep dev's ci.yml with the CAR-1316 tag=sha-${GITHUB_SHA} consumer-side fix and CAR-1318 ghcr.io/cartsnitch/app=... kustomize bump.
  • 9b922aa (vite preview bind) applied cleanly on top with 3-line comment-only change (the npx vite preview --host 127.0.0.1 line is already in dev via #281).

Final commit list (3 commits on top of dev):

  • 446cf66 fix(ci): bind vite preview to 127.0.0.1, not localhost (CAR-1218) — comment-only (3 lines)
  • b0cb2b7 ci: retrigger CI for CAR-1334 (CAR-1302) — empty retrigger
  • a54ea42 fix(api): widen alembic_version.version_num in migration 001 (CAR-1302) — the durable root fix for CAR-1298

Validation:

  • mergeable: true on Gitea (base ad18a43b5 = current dev head)
  • Actions run #3470 (446cf66): completed, conclusion success
  • Alembic diff vs dev: 4 files, +51/-41 (env.py version_table_column_width removed, 001_encrypt_session_data.py widened, 001_add_email_inbound_token.py added, ci.yml unchanged from dev)

Proceeding to self-merge dev per SDLC Phase 1.

Rebased onto current dev head `ad18a43b5` (CAR-1364 followup). **Reconciliation:** - Git auto-dropped `71e3b81 fix(ci): lighthouse step-level continue-on-error` because the patch content is already on dev via #281 (CAR-1218). - Conflict in `.gitea/workflows/ci.yml` (e750aa6 job-level continue-on-error vs dev's CAR-1316/1318 deploy fixes) was resolved by taking dev's version.
