From: Jonathan Tan Date: Tue, 1 Sep 2020 22:28:07 +0000 (-0700) Subject: sha1-name: replace unsigned int with option struct X-Git-Tag: v2.29.0-rc0~82^2~2 X-Git-Url: http://git.ipfire.org/?p=thirdparty%2Fgit.git;a=commitdiff_plain;h=a4f66a7876f6979f0a3ac254173cbdaf0a2a55c3 sha1-name: replace unsigned int with option struct In preparation for a future patch adding a boolean parameter to repo_interpret_branch_name(), which might be easily confused with an existing unsigned int parameter, refactor repo_interpret_branch_name() to take an option struct instead of the unsigned int parameter. The static function interpret_branch_mark() is also updated to take the option struct in preparation for that future patch, since it will also make use of the to-be-introduced boolean parameter.
