Refactored masking from QOutProcessor#maskPatterns that involves file rewrite to in-memory implementation for CliDriver and BeeLine.
What changes were proposed in this pull request?
Removed
QOutProcessor#maskPatterns()which rewrites the whole file when masking.Added in-stream masking methods and states, including
maskAndFoldLine(),maskLines(),maskContent(), andMaskingFoldStatewhile retaining the original semantics. Splitted multilineprintln()on \n for PREHOOK/POSTHOOK textWrapped both stdout and stderr with QTestFetchConverter to perform mask before sort for CliDriver. For BeeLine retained original sort before mask behaviour and applied masking on the
!recordstream.Why are the changes needed?
Currently masking may be applied in multiple locations and also involves re-writing the q.out files after test execution, causing duplicate effort. The change performs masking in memory on the capture stream.
Does this PR introduce any user-facing change?
No.
How was this patch tested?
Tested and validated with multiple existing qfiles with
TestMiniLlapLocalCliDriver,TestMiniLlapCliDriver,TestCliDriver,TestMiniTezCliDriver,TestBeeLineDriverAlso added unit test under
TestQOutProcessor
