From: Johan Herland Date: Mon, 12 Mar 2012 14:57:13 +0000 (+0100) Subject: notes-merge: use opendir/readdir instead of using read_directory() X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a0be62c100897573ef1575ec0d5e8b215e9dcafe;p=git.git notes-merge: use opendir/readdir instead of using read_directory() notes_merge_commit() only needs to list all entries (non-recursively) under a directory, which can be easily accomplished with opendir/readdir and would be more lightweight than read_directory(). read_directory() is designed to list paths inside a working directory. Using it outside of its scope may lead to undesired effects. Apparently, one of the undesired effects of read_directory() is that it doesn't deal with being given absolute paths. This creates problems for notes_merge_commit() when git_path() returns an absolute path, which happens when the current working directory is in a subdirectory of the .git directory.
