2021-06-08t: fix whitespace around &&Libravatar Andrei Rybak1-1/+1
Add missing spaces before '&&' and switch tabs around '&&' to spaces. These issues were found using `git grep '[^ ]&&$'` and `git grep -P '&&\t'`. Signed-off-by: Andrei Rybak <rybak.a.v@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-10-29log, show: add tests for messages containing CRLFLibravatar Philippe Blain1-0/+18
A previous commit adjusted the code in ref-filter.c so that messages containing CRLF are now correctly 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.

2020-10-29ref-filter: handle CRLF at end-of-line more gracefullyLibravatar Philippe Blain1-0/+108
The ref-filter code does not correctly handle commit or tag messages that use CRLF as the line terminator. Such messages can be created with the `--cleanup=verbatim` option of `git commit` and `git tag`, or by using `git commit-tree` directly. The function `find_subpos` in ref-filter.c looks for two consecutive LFs to find the end of the subject line, a sequence which is absent in messages using CRLF. This results in the whole message being parsed as the subject line (`%(contents:subject)`), and the body of the message (`%(contents:body)`) being empty. Moreover, in `copy_subject`, which wants to return the subject as a single line, '\n' is replaced by space, but '\r' is untouched. This impacts the output of `git branch`, `git tag` and `git for-each-ref`. This behaviour is a regression for `git branch --verbose`, which bisects down to 949af0684c (branch: use ref-filter printing APIs, 2017-01-10). Adjust the ref-filter code to be more lenient by hardening the logic in `copy_subject` and `find_subpos` to correctly parse messages containing CRLF. Add a new test script, 't3920-crlf-messages.sh', to test the behaviour of commands using either the ref-filter or the pretty APIs with messages using CRLF line endings. The function `test_crlf_subject_body_and_contents` can be used to test that the `--format` option of `branch`, `tag`, `for-each-ref`, `log` and `show` correctly displays the subject, body and raw content of commit and tag messages using CRLF. Test the output of `branch`, `tag` and `for-each-ref` with such commits.
