[PATCH v4 0/2] ref-filter: handle CRLF at end-of-line more gracefully

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

 



Changes since v3 :

 * removed lib-crlf-messages.sh and the changes to the existing test
   scripts, and instead added a new test script : t3920-crlf-messages.sh,
   and adjusted the commit message of 1/2 (which was 2/3 in v3) accordingly.
 * tweaked the code and the test script to be in line with the C and shell
   coding guidelines, following comments by Junio and Eric
 * made the generation of the crlf-* refs and helper files in the test
   script more readable and automated, as suggested by Eric.

Notes: 

 1. I was really unsure about which number to choose for the new script, so
    I chose one available at the end of section 3 ("the other basic commands
    " according to t/README), so I'll change that if we come up with a
    better number.
 2. the automated range-diff generated by Gitgitgadget (at the end of the
    cover) will be mostly useless because of the refactoring of the test
    library into a test script. So I'm including a few (manually edited)
    blob diffs (git diff v3:file v4:other-file) below to make reviewing
    easier.

----------------------------------------------------------------------------

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 '\n' 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, '\n' is replaced by space, but '\r' is untouched.

This bug is a regression for git branch --verbose, which bisects down to
949af06 (branch: use ref-filter printing APIs, 2017-01-10).

The first patch fixes the bug in ref-filter.c and adds a test script to
check that the ref-filter and pretty APIs deal correctly with CRLF messages.

The second patch adds tests that check the behaviour of git log andgit show 
in the presence of CRLF in messages, to prevent futur regressions.

Philippe Blain (2):
  ref-filter: handle CRLF at end-of-line more gracefully
  log, show: add tests for messages containing CRLF

     -    The 'make commits' test at the beginning of t3203-branch-output.sh does
