[PATCH v3 3/3] log, show: add tests for messages containing CRLF

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Philippe Blain <levraiphilippeblain@xxxxxxxxx>

A previous commit fixed a bug in ref-filter.c causing messages
containing CRLF to be incorrectly parsed and displayed.

Add tests to also check that `git log` and `git show` correctly handle
such messages, to prevent futur regressions if these commands are
refactored to use the ref-filter API.

To prevent having to modify expected output in further tests, use
'test_cleanup_crlf_refs' in t4202 to clean-up after the added tests.
