Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to This disposable CI-validation change is otherwise mergeable, but the probe instructions do not identify the exact temporary marker to apply, so reproducing the ASAN-only validation is less reliable and should be clarified before use.

Learning: In `lib/mysql_connection.cpp`, when reviewing `SHOW WARNINGS` handling, treat the digest source as an intentional design choice: both `update_warning_count_from_connection()` and the `add_eof()` call under `ASYNC_USE_RESULT_CONT` detect warnings using `myds->sess->CurrentQuery.QueryParserArgs.digest_text` (comment-stripped digest text). This is expected to fail/behave differently when `mysql-query_digests_keep_comment=1` (digest_text includes comments) or when `mysql-query_digests=0` (digest_text unavailable). Do not require a change unless the regression test coverage is expanded (noting `reg_test_5306-show_warnings_with_comment-t` explicitly excludes these configurations as an accepted limitation).

Learning: When using GitHub-flavored Markdown headings, be aware that an em-dash surrounded by spaces (written as ` — `) affects the generated anchor/slug: GitHub replaces spaces with hyphens and removes non-alphanumeric punctuation, which can produce double hyphens (e.g., `## Foo — bar` → anchor `#foo--bar`, not `#foo-bar`). If you reference these anchors (e.g., internal links), ensure the expected slug matches this behavior.

Learning: When reviewing GitHub-flavored Markdown links/anchors, remember that heading-to-anchor slug generation treats spaces as hyphens and removes punctuation. If a heading contains an em-dash surrounded by spaces (e.g. ` — `), the slugs can legitimately include a double hyphen where the two surrounding space-runs become `-` on either side of the removed em-dash (e.g. `...vocabulary--read...`). Do not flag double-hyphens in anchor links for em-dash-containing headings as errors; they reflect GitHub’s correct slug behavior.

Name the exact non-ignored trigger.
The procedure requires a later non-ignored no-op change, but it does not identify the intended .gitignore change. Reference .gitignore Line 244 so operators do not create an unrelated change.

⚠️ Bug: PSQL40 define gated on passed-in flag, not autodetected archive
The new -DPROXYSQL40 define in test/tap/tests/Makefile is gated on ifeq ($(PROXYSQL40),1), i.e. the flag must be passed in the environment. But this Makefile already autodetects the archive's real ABI via PROXYSQL40_DETECTED (nm probe of invoke_register_schemas_phase) and uses that for test filtering. The sibling test/tap/tests/unit/Makefile instead gates its PSQL40 directly on the same symbol probe. Per this PR's own premise (the central build hands binaries to separate TAP workflows where build flags are no longer available — the exact reason asan-detection.bash inspects the binary), PROXYSQL40 may be empty when building TAP tests against a PROXYSQL40 archive. In that case PSQL40 stays empty and TAP translation units are compiled with a smaller ProxySQL_GlobalVariables layout than the constructor linked from libproxysql.a — reintroducing exactly the memory-safety/UAF mismatch the comment says it prevents. Gate the define on the detected value instead (and move the detection above the OPT assignment, since OPT/PSQL40 use immediate := and PROXYSQL40_DETECTED is currently defined further down at line 222).
Derive the -DPROXYSQL40 define from the archive symbol probe (matching unit/Makefile) rather than the externally-passed flag, and relocate the PROXYSQL40_DETECTED assignment before the OPT/DEBUG_OPT definitions.:
# (move LIBPROXYSQLAR + PROXYSQL40_DETECTED detection above this block)
PSQL40 :=
ifneq ($(PROXYSQL40_DETECTED),0)
PSQL40 := -DPROXYSQL40
endif

Purpose
Disposable end-to-end validation of the merged
ci:asanselector.The initial Markdown-only commit intentionally does not start
CI-trigger. After applyingci:asan, a harmless non-ignored.gitignorecomment will trigger the ASAN-selected run.This PR must not be merged and will be closed after validation.
Summary by cubic
Finalize PgSQL poisoned simple-query requests before freeing the packet to remove a use-after-free, and validate label-selected ASAN CI. Previously we freed the packet before RequestEnd; now we call RequestEnd first, then free, preserving logging and parser cleanup.
proxysqlfor libasan, exports WITHASAN/ASAN_OPTIONS into isolated Docker runs, raises per-test TAP timeouts under ASAN, disables LeakSanitizer for daemon processes, and adds a self-test for the detector.PROXYSQL40to matchlibproxysqlclass layouts; REST API and cluster tests increase endpoint and shutdown timeouts when WITHASAN=1.ci:asan, then push a non-ignored no-op to trigger the ASAN-only workflow; confirm only ASAN-selected jobs run and the UAF no longer reproduces inpgsql-retry_guard_in_txn_on_broken_backend-t. Retries are added for transient LFS checkout failures. Do not merge; close after validation.Written for commit e537e90. Summary will update on new commits.
