Summary

Two follow-ups promised in the review of #1165, and the outcome of #1502.

  • Nightly downloads time out. The real-data job's curl had no timeout, so a stalled connection to census.gov could hold the job, and the report job waiting on it, for GitHub's six hours. Each download now has --connect-timeout 30 --max-time 300 --retry-max-time 600, about 15 minutes a file at most, which takes the existing "could not download, skip" path. The job has timeout-minutes: 60 (it takes 6 to 10 minutes).
  • A job that runs out of time is reported. It ends cancelled, which the report skipped; the report now runs unless the run itself was cancelled, so it counts as a failure.
  • Only a full set of Census files is cached. The cache is restored and saved as separate steps, saved once every file downloaded and matched its checksum. The combined action saved a set missing a file, and an exact hit is never saved again.
  • A null assessment is checked through the overlay. The parcel job's assessment table now has no row for 00103 as well as 00112. 00103 straddles the R1/C2 boundary, so check_values(&zoned) now sees two pieces whose joined value must stay Null. 00112 is in no zone and makes no piece, so until now every piece the overlay checked had a value. The test also checks those two pieces directly.

Testing

  • cargo test -p rustgis-engine --test workflows: passes, with 12 parcels joined and 13 pieces checked, two of them null. The null pieces also go through the GeoPackage round trip.
  • nightly.yml parses; only the curl line and the job's timeout-minutes change.
  • cargo xtask ci before the commit.

UI evidence

No visible UI change.

Related issue

Follow-up to #1165.

#1502 needs nothing more here. Its two failures are already fixed on main:

  • cache::tests::fetches_through_the_fetcher_once (Linux, 11-06): the race deniial00 diagnosed. Tests in shapes.rs and picture.rs read a PMTiles archive through the cache without taking the cache's turn, so one could hold the shared start flag while this test's fetch was parked behind it. fix(security): bind approvals to exact execution scopes #1461 gave those 12 tests the turn. A local probe that logs any test thread starting a cache fetch without the turn found those tests before the change and none after.
  • cache::tests::a_later_wait_isnt_lost_behind_an_earlier_one (macOS, 11-07): a test that relied on real sleeps, which fix(security): keep credentials within runtime boundaries #1521 replaced with a deterministic check of take_due.

The issue closes itself on the next nightly that passes.

Summary by CodeRabbit

  • Chores
    • The nightly workflow has a 60-minute limit. Census downloads retain retries and warning-and-continue behavior, with connection and transfer time limits. Downloaded files are cached only after successful downloads, and the scheduled report runs unless the workflow is cancelled.
  • Tests
    • Workflow test data now includes parcels without assessments, including one split across two zones. Expected results reflect the missing assessment values for both pieces.

…a null assessment through the overlay

The real-data job's curl had no timeout, so a stalled connection to
census.gov could hold the job, and the report waiting on it, for
GitHub's six hours. Each download now gives up after 30 s to connect or
10 minutes in all, which takes the existing "could not download, skip"
path, and the job stops after an hour (it takes about ten minutes).

The parcel job's assessment table now has no row for "00103" as well as
the last parcel. "00103" straddles the R1/C2 boundary, so the overlay
check now sees two pieces whose joined value must stay null; the last
parcel is in no zone and made no piece, so nulls were never checked
through the overlay before.

Both were promised in review of opengeos#1165.

Walkthrough

The nightly workflow now has a 60-minute job timeout, bounded census downloads, separate cache restore and save steps, and an updated report condition. Workflow tests now omit assessments for parcel indices 2 and 11 and verify null values for both overlay pieces of parcel 00103.

Changes: Nightly workflow

Layer / File(s) Summary
Update nightly download and report steps
.github/workflows/nightly.yml
The workflows job has a 60-minute timeout. Census downloads use a 30-second connection timeout and a 300-second maximum transfer time. Cache saving requires successful downloads and a cache miss. The report job runs when the workflow is not cancelled.

Parcel assessment workflow tests

Layer / File(s) Summary
Represent unassessed parcels in workflow tests
crates/engine/tests/workflows.rs
Fixture generation omits assessment rows for indices 2 and 11, and the assessment helper returns Null for both. The test verifies that parcel 00103 has two overlay pieces and that both have null values.

Timeouts don't add up to the skip path. With --retry 3 and --max-time 600, a stalled Census host can take 4 attempts × 600 s ≈ 40 min for one file. The loop has two files, so a persistent stall can run past the job's new timeout-minutes: 60 before the "could not download, skip" branch runs. GitHub then fails the job, and report treats workflows as failure and opens a "Nightly build failed" issue. That is the false alarm this PR is meant to avoid, and incomplete is the intended result.

Keeping the 600 s per-attempt cap and cutting retries to one bounds each file at about 20 min, so two files stay under 60 min:

Suggested change
curl -sSfL --retry 3 --connect-timeout 30 --max-time 600 -o "$file" "$url" || { echo "::warning::could not download $url"; ok=false; continue; }
curl -sSfL --retry 1 --connect-timeout 30 --max-time 600 -o "$file" "$url" || { echo "::warning::could not download $url"; ok=false; continue; }

If you'd rather keep --retry 3, raise timeout-minutes above the worst case (about 90) instead. Confidence: medium-high. I haven't run the workflow, so this is from reading the YAML and curl's retry behaviour.

Fixed in 7efba11: --max-time 300 --retry-max-time 600, so a file gives up after about 15 minutes and both fit within the job's hour, leaving time for the build. The larger file is 15.6 MB, so 5 minutes an attempt is ample.

Code review

Bugs

  • Download budget can outlast the new job cap (.github/workflows/nightly.yml:91, confidence medium-high). --retry 3 --max-time 600 allows about 40 min per file. A persistent stall on two files exceeds the new timeout-minutes: 60. The job then fails instead of taking the skip path, and report opens a "Nightly build failed" issue. Suggested fix: --retry 1 (about 20 min per file), or raise the job timeout to about 90. Posted inline.

Security

  • None found. The change only adds curl timeouts and a job timeout; the checksum verification is unchanged.

Performance

  • None found.

Quality

  • Test-only underflow (crates/engine/tests/workflows.rs:492, confidence high, minor). parcel.parse::<usize>() - 101 now panics with an arithmetic-overflow message for an id below 00101, where the previous i64 version returned a mismatch. It only affects test code. I'm leaving it for the release quality pass.

AGENTS.md

  • None found. The test code uses panic! and unwrap only inside tests, and the download still reports failures through ::warning:: with the URL.

Verified

  • I checked the test data against the geometry. SPLIT = WEST + 2.5·STEP, so parcel 00103 is split into two pieces, both with no value. Parcel 00107 is split too, but it has a row. That gives 13 pieces with 2 null, matching the PR's claim. Parcel 00112 falls in no zone and makes no piece. The parcel_id mapping (k → 101 + k) is consistent with unassessed.
  • The prior-review file has no threads, so nothing was deduplicated.
  • I did not run the tests or the workflow. The claims above come from reading the code.

- Line 91: Adjust the download retry budget in the curl command so repeated
timeouts across both uncached files cannot consume the job’s 60-minute timeout;
reserve sufficient time for setup and reporting to ensure the incomplete-run
status is recorded. Preserve the existing warning and `ok=false` handling.
- Line 91: Update the nightly workflow’s download and cache flow so the cache is
saved only after both checksum validations pass, and rotate the cache key to
invalidate entries created by the current behavior. Preserve the existing
download and checksum checks, and ensure a failed or incomplete download cannot
be cached or cause the tests to be skipped on a later run.
- Line 68: Update the report job condition in the nightly workflow so a timeout
of the real-data job still opens or updates the nightly issue, while an
intentional workflow cancellation continues to skip the report. Use the job
result and workflow cancellation state to distinguish these cases; preserve the
existing behavior for other outcomes.

Review comments at @crates/engine/tests/workflows.rs:
- Line 487: Update the split-parcel assertions in the workflow test to
independently verify that exactly two pieces for parcel 00103 have null
assessments, rather than relying on the fixture and expected values changing
together; retain the existing checks for other parcel pieces.

…ll set, report a job that runs out of time

Each download now stops retrying after 10 minutes, with 5 minutes per
attempt: with --retry 3 and 10 minutes an attempt, two stalled files
could outlast the job's hour and fail it rather than skip the tests.

The Census files are restored and saved as separate steps, saved only
when every file downloaded and matched its checksum: the combined action
saved a set missing a file, and an exact hit is never saved again.

The report runs unless the run itself was cancelled. A job that runs
out of time ends cancelled, which the report skipped; it now counts as
a failure.

The job test also checks that both of 00103's pieces have no
assessment, apart from the fixture's helper.

Existing -1 cache entry may still hold an incomplete set. The new restore/save split only stops new incomplete saves. The earlier combined actions/cache step saved whatever files were present when the job succeeded, and the data step succeeds even when ok=false. So a -1 entry from a run with a failed download can already exist. An exact hit then never triggers a save, and the missing file is downloaded on every run. This is the part of the earlier "rotate the existing key" thread that this PR does not address. Bumping the key to -2 in both places (here and in the "Keep the Census files" step at line 107) makes the first verified run repopulate the cache. Confidence: medium. I can't inspect the cache contents from here.

No -1 entry exists to rotate. gh cache list --key workflow-data returns nothing, and every nightly run from 11-01 to 11-07 logs Cache not found for input keys: workflow-data-census-2024-1, downloads both files, and saves again. The entry is evicted between nights, so none can be left half-filled, and the key stays.

Code review

Bugs

  • Existing cache key may hold an incomplete set (.github/workflows/nightly.yml:83, medium confidence). The restore/save split stops new partial saves, but a -1 entry saved by the old combined action can still exist. Exact hits are never re-saved, so the missing file is re-downloaded on every run. Bumping the key to -2 in both places fixes it. Posted inline.

Security

  • None found. The download loop still verifies SHA-256 before using a file, and a changed checksum exits non-zero.

Performance

  • None found. The download timeouts bound the worst case to about 15 minutes per file, so roughly 30 minutes for both. That fits the new timeout-minutes: 60.

Quality

  • None worth posting. The reviewer notes I'd leave for the release quality pass are the value loop variable shadowing the Value import name, and the - 101 subtraction in the test helper, which panics on underflow only for ids below 101 and only in test code.

AGENTS.md

  • None found. The new workflow and test code are not subject to the no-panic rule (test-only), and the download path's skip-with-warning behaviour is unchanged.

Checked and found sound

  • Report job: !cancelled() skips only on a run-level cancel. A workflows job that times out (cancelled or failed) yields RESULT=failure and opens the issue. A download failure still yields incomplete.
  • Cache save gating: save runs only when ok == 'true' and not on a cache hit. The cache-hit output name matches actions/cache/restore.
  • Test fixture: unassessed(2) is 00103 and unassessed(11) is 00112. 00103 straddles the zone boundary, and 00112 lies outside both zones. The new 00103 assertions hard-code Field::Null, so they don't depend on unassessed.

Prior threads

I left 4 earlier concerns alone and didn't repost them. Two were about the retry budget, and the PR's --retry-max-time 600 --max-time 300 now bounds it. One was about caching only verified sets, which the ok == 'true' gate now does. The timeout-as-failure and null-assertion threads are resolved in the code. The key-rotation part of the cache thread is still open, and I raised it again inline because the line it points at has changed.
