[PATCH] gcc-changelog: Accept ref_name argument in GitCommit.

[PATCH] gcc-changelog: Accept ref_name argument in GitCommit.

[Martin Liška]

Hello.



As Jakub correctly noticed, we can remove ChangeLog locations only based

on branch (master, a release branch). The patch removes 2 locations for the current

master (or any further release) based on the current master.



gccadmin/hooks-bin/commit_checker needs to be updated correspondingly with:


         commits = parse_git_revisions(os.environ['GIT_DIR'], commit_rev, ref_name)

Thoughts?
Martin

contrib/ChangeLog:

	* gcc-changelog/git_commit.py: Remove ChangeLog locations
	based on ref_name.
