fix(ci): validate cached dbt e2e environments; pin the uv venv to the system Python - #1258
anandgupta42 wants to merge 7 commits into
Conversation
… system Python The dbt-tools E2E job on main fails with ENOENT executing test/.dbt-resolve-envs/uv/.venv/bin/dbt: the restored cache holds a uv venv whose bin/python links to a uv-managed interpreter outside the cached directory, absent on a fresh runner. setup-resolve.sh trusted the .done marker and skipped setup, and actions/cache never re-saves on a hit, so the broken environment came back on every run. - setup-resolve.sh: a cached environment counts only if its dbt --version runs (with a timeout); otherwise it is rebuilt. Applied to every scenario. - uv venv is created with --python "$REAL_PYTHON" so it links to an interpreter that exists on every runner. - ci.yml: cache key bumped to -v2 so the broken v1 cache is not restored.

The job this PR fixes now runs on the PR itself and passes: dbt-tools E2E, 1m03s, https://github.com/AltimateAI/altimate-code/actions/runs/34162722805/job/101867732074 (cache miss on the v2 key, fresh build with the pinned interpreter, all resolver e2e tests green). The first push to main after merging exercises the cache-restore path; if that ever regresses, the setup script now rebuilds instead of trusting the marker. |

Both build onDBT_E2E_PYTHONwhen set, and the uv venv is created with--pythonso it links to that interpreter.dbt-versions.test.ts): whenDBT_E2E_VERSIONSis set (CI sets it), a requested version without a working dbt that reports that version fails the run instead of skipping. Each version'sbeforeAllnow callsconfigure()with its own venv. The tests never reset the dbt binarydbt-clicaches, so every version after the first ran the first one's dbt; it surfaced as 4 dbt 1.11 failures (a DuckDB file written by 1.11 that 1.10 cannot read).ci.yml): both cache keys include the setup-python version, so a new 3.11 patch release starts fresh caches instead of restoring dead venvs; the scenario key also moves to-v2. Both setup steps getDBT_E2E_PYTHONfrom setup-python. The job also runs on PRs that touchpackages/dbt-tools/**, with a read-only token and no persisted credentials, so a fix to its own setup is proven before merge.How did you verify your code works?

.donepresent,bin/dbton disk) butdbtexited with ENOENT because the uv venv pointed at a uv-managed Python outside the cached tree.setup-resolve.shnow treats a cache hit as valid only afterdbt --versionsucceeds (with optionaltimeout); stale caches are rebuilt with a clear message. uv venvs are created with--python "$REAL_PYTHON", andDBT_E2E_PYTHONlets CI prefersetup-python’s interpreter over the image default. All scenarios share acached_or_rebuildhelper instead of trusting.donealone..github/workflows/ci.ymlbumps the resolve-env cache key v1 → v2, passesDBT_E2E_PYTHONinto setup, and runs dbt-tools E2E on PRs that touchpackages/dbt-tools(not only on push to main).
