From: Christian Couder Date: Mon, 6 Apr 2009 19:28:36 +0000 (+0200) Subject: list-objects: add "void *data" parameter to show functions X-Git-Tag: v1.6.3-rc0~7^2~2 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=11c211fa06fc396e8ee8132ef83e2f2763ff6976;p=git.git list-objects: add "void *data" parameter to show functions The goal of this patch is to get rid of the "static struct rev_info revs" static variable in "builtin-rev-list.c". To do that, we need to pass the revs to the "show_commit" function in "builtin-rev-list.c" and this in turn means that the "traverse_commit_list" function in "list-objects.c" must be passed functions pointers to functions with 2 parameters instead of one. So we have to change all the callers and all the functions passed to "traverse_commit_list". Anyway this makes the code more clean and more generic, so it should be a good thing in the long run.
