The size-accounting INSERT in StoreVariant used db.Exec, and
StoreVariant took no context at all, so the write was uncancellable and
untraceable. Rather than paper over that with context.Background() at
the call site, StoreVariant now takes a context.Context and uses
ExecContext.
The plumbing is small: the only production caller is
Service.processAndStore, which already has the request context in
scope, so the accounting insert now shares the lifetime of the request
that produced the variant. Test callers pass t.Context().
The insert remains best-effort: a failure is logged and the startup and
periodic reconciliation passes still adopt any variant file whose
accounting row is missing.
No behavior changes. Covers the purely mechanical findings the canonical
v2.12.2 config raises on the cache-size/eviction work:
- nolintlint: deleted 7 dead //nolint:gosec directives (cachesize.go x2,
config.go, eviction.go x2, storage.go x2). gosec never raises G115/G703
on those lines under the pinned toolchain, exactly the defect class
that failed round 2 of this PR. The 6 live gosec suppressions are
untouched.
- funcorder: moved writeIfAbsent after Exists (storage.go) and
touchVariant/touchSourceContent after IncrementStats (cache.go).
- lll: wrapped over-length signatures, calls and messages at 88 columns.
- paralleltest: t.Parallel() on the new eviction, contentlock and
cache_max_bytes tests and their subtests. configFromYAML uses only
t.TempDir, so the config cases are parallel-safe.
- noctx: test helper DB calls now use ExecContext/QueryContext/
QueryRowContext with t.Context().
- goconst: extracted testHeaderContentType into the shared test constant
block and testVariantKeyOne into the eviction tests; reused the
existing testContentTypeJPEG and keyCacheMaxBytes constants.
- modernize: interface{} to any, atomic.Int32 for the contentlock
counters, min/max in ComputeDefaultCacheMaxBytes.
- intrange: integer range loops in the contentlock tests.
- wsl_v5: whitespace before the contentlock rendezvous statements.
- sloglint: slog.DiscardHandler in the config test logger.
- cyclop/funlen: split TestZeroMaxBytesDisablesDiskCache into four
assertion helpers and extracted the concurrent store goroutine from
TestEvictSourceBlobExcludesConcurrentStoreOfIdenticalContent. Every
assertion is preserved verbatim; only their grouping changed.
Replace .golangci.yml with the canonical v2-schema config
(default: all minus six disabled linters, lll 88, tests included)
and bump every golangci-lint pin to v2.12.2:
- Dockerfile: golangci/golangci-lint:v2.12.2-alpine (hash-pinned)
- script/bootstrap: GOLANGCI_LINT_VERSION 2.12.2 with new
linux-amd64/arm64 release-archive sha256 pins
Fix all 747 findings the stricter config surfaces, with no behavior
changes: t.Parallel() throughout the test suite, static sentinel
errors and errors.Is comparisons, checked error returns, context
propagation (contextcheck/noctx), 88-column wrapping, extracted
constants and helpers for goconst/dupl/funlen/cyclop, exhaustive
switch cases replicating existing defaults, and white-box test files
renamed to *_internal_test.go for testpackage. Three
nolint:tagliatelle directives preserve the existing snake_case JSON
wire and on-disk metadata formats.
