sql_functions.go (850+ lines) - sql_functions_test.go (1,205+ lines) **File Structure After:** - function_helpers.go (105 lines) - shared utility functions - arithmetic_functions.go (205 lines) - arithmetic operators & math functions - datetime_functions.go (170 lines) - date/time functions & constants - string_functions.go (335 lines) - string manipulation functions - arithmetic_functions_test.go (560 lines) - tests for arithmetic & math - datetime_functions_test.go (370 lines) - tests for date/time functions - string_functions_test.go (270 lines) - tests for string functions **Benefits:** ✅ Better organization by functional domain ✅ Easier to find and maintain specific function types ✅ Smaller, more manageable file sizes ✅ Clear separation of concerns ✅ Improved code readability and navigation ✅ All tests passing - no functionality lost **Total:** 7 focused files (1,455 lines) vs 2 monolithic files (2,055+ lines) This refactoring improves maintainability while preserving all functionality. * fix: Improve test stability for date/time functions **Problem:** - CURRENT_TIMESTAMP test had timing race condition that could cause flaky failures - CURRENT_DATE test could fail if run exactly at midnight boundary - Tests were too strict about timing precision without accounting for system variations **Root Cause:** - Test captured before/after timestamps and expected function result to be exactly between them - No tolerance for clock precision differences, NTP adjustments, or system timing variations - Date boundary race condition around midnight transitions **Solution:** ✅ **CURRENT_TIMESTAMP test**: Added 100ms tolerance buffer to account for: - Clock precision differences between time.Now() calls - System timing variations and NTP corrections - Microsecond vs nanosecond precision differences ✅ **CURRENT_DATE test**: Enhanced to handle midnight boundary crossings: - Captures date before and after function call - Accepts either date value in case of midnight transition - Prevents false failures during overnight test runs **Testing:** - Verified with repeated test runs (5x iterations) - all pass consistently - Full test suite passes - no regressions introduced - Tests are now robust against timing edge cases **Impact:** 🚀 **Eliminated flaky test failures** while maintaining function correctness validation 🔧 **Production-ready testing** that works across different system environments ⚡ **CI/CD reliability** -

Add shared lock to GetAttr when accessing file handle entries - Prevents concurrent access between Write (ExclusiveLock) and GetAttr (SharedLock) - Fixes race on entry.Attributes.FileSize field during concurrent operations - Write operations already use ExclusiveLock, now GetAttr uses SharedLock for consistency Resolves race condition: Write at weedfs_file_write.go:62 vs Read at filechunks.go:28 * Update weed/mq/broker/broker_grpc_query.go Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> * clean up * Update db.go * limit with offset * Update Makefile * fix id*2 * fix math * fix string function bugs and add tests * fix string concat * ensure empty spaces for literals * add ttl for catalog * fix time functions * unused code path * database qualifier * refactor * extract * recursive functions * add cockroachdb parser * postgres only * test SQLs * fix tests * fix count * * fix where clause * fix limit offset * fix count fast path * fix tests * func name * fix database qualifier * fix tests * Update engine.go * fix tests * fix jaeger https://github.com/advisories/GHSA-2w8w-qhg4-f78j * remove order by, group by, join * fix extract * prevent single quote in the string * skip control messages * skip control message when converting to parquet files * psql change database * remove old code * remove old parser code * rename file * use db * fix alias * add alias test * compare int64 * fix _timestamp_ns comparing * alias support * fix fast path count * rendering data sources tree * reading data sources * reading parquet logic types * convert logic types to parquet * go mod * fmt * skip decimal types * use UTC * add warning if broker fails * add user password file * support IN * support INTERVAL * _ts as timestamp column * _ts can compare with string * address comments * is null / is not null * go mod * clean up * restructure execution plan * remove extra double quotes * fix converting logical types to parquet * decimal * decimal support * do not skip decimal logical types * making row-building schema-aware and alignment-safe Emit parquet.NullValue() for missing fields to keep row shapes aligned. Always advance list level and safely handle nil list values. Add toParquetValueForType(...) to coerce values to match the declared Parquet type (e.g., STRING/BYTES via byte array; numeric/string conversions for INT32/INT64/DOUBLE/FLOAT/BOOL/TIMESTAMP/DATE/TIME). Keep nil-byte guards for ByteArray. * tests for growslice * do not batch * live logs in sources can be skipped in execution plan * go mod tidy * Update fuse-integration.yml * Update Makefile * fix deprecated * fix deprecated * remove deep-clean all rows * broker memory count * fix FieldIndex --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>	2 weeks ago
