📝 Walkthrough

Walkthrough

Modified Makefile test and coverage targets to use a new Bazel configuration variable BAZEL_TEST_CMD_CONFIG that includes --norun_validations flag. Updated multiple test targets across real-TiKV test suite, and adjusted the bazel_coverage_test target to use HOST_CPUS instead of a fixed job count.

Changes

Cohort / File(s)	Summary
Bazel Test Configuration Variable Makefile.common	Added new variable BAZEL_TEST_CMD_CONFIG extending BAZEL_CMD_CONFIG with --norun_validations flag.
Bazel Test Targets Makefile — bazel_test, bazel_brietest, bazel_pessimistictest, bazel_sessiontest, bazel_statisticstest, bazel_txntest, bazel_pushdowntest, bazel_addindextest*, bazel_importintotest*, bazel_pipelineddmltest, bazel_flashbacktest, bazel_ddltest	Rewired test invocations to use $(BAZEL_TEST_CMD_CONFIG) instead of $(BAZEL_CMD_CONFIG), disabling validations during test execution.
Coverage Test Target Makefile — bazel_coverage_test	Updated to use $(BAZEL_TEST_CMD_CONFIG) and changed --jobs=35 to --jobs=$(HOST_CPUS) for dynamic job count allocation.

Poem

🐰 A hop through the Makefile so bright,
With validations now off for test night,
The jobs dance with CPU's call,
Configuration simplified for all! ✨

🚥 Pre-merge checks | ✅ 1 | ❌ 2

❌ Failed checks (1 warning, 1 inconclusive)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 46.43% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Description check	❓ Inconclusive	The PR description is incomplete. While it references an issue and marks unit tests as included, it lacks a clear 'What changed and how does it work' section explaining the Makefile and Makefile.common modifications.	Add detailed explanation of changes: describe the new BAZEL_TEST_CMD_CONFIG variable, which Makefile targets were updated, and why --norun_validations is needed for the mentioned issue.

✅ Passed checks (1 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'build: disable bazel test validations' is clear and directly summarizes the main change—disabling Bazel test validations via the new BAZEL_TEST_CMD_CONFIG variable with --norun_validations flag.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}

In `@pkg/planner/util/null_misc.go`:
- Around line 74-77: The call to MaybeOverOptimized4PlanCache inside
allConstants (and similar sites) ignores the skipPlanCacheCheck flag; thread the
skipPlanCacheCheck boolean through proveNullRejected → tryFoldNullifiedConstant
→ tryFoldStaticConstant → allConstants (and other affected locations) and only
call MaybeOverOptimized4PlanCache when skipPlanCacheCheck is false, so callers
that set skipPlanCacheCheck=true can bypass the plan-cache guard and still prove
null-rejection; update function signatures (e.g., proveNullRejected,
tryFoldNullifiedConstant, tryFoldStaticConstant, allConstants) to accept the
flag and propagate it accordingly.

with the remote cache, disabling static check seems that it doesn't help a lot.
