X-Git-Tag: v1.5.2-rc0~99^2 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/9fc42d609197ef331f1c5b2ce5ef6fc9f2ee634f?ds=inline;hp=9fc42d609197ef331f1c5b2ce5ef6fc9f2ee634f Optimize directory listing with pathspec limiter. The way things are set up, you can now pass a "pathspec" to the "read_directory()" function. If you pass NULL, it acts exactly like it used to do (read everything). If you pass a non-NULL pointer, it will simplify it into a "these are the prefixes without any special characters", and stop any readdir() early if the path in question doesn't match any of the prefixes. NOTE! This does *not* obviate the need for the caller to do the *exact* pathspec match later. It's a first-level filter on "read_directory()", but it does not do the full pathspec thing. Maybe it should. But in the meantime, builtin-add.c really does need to do first read_directory(dir, .., pathspec); if (pathspec) prune_directory(dir, pathspec, baselen); ie the "prune_directory()" part will do the *exact* pathspec pruning, while the "read_directory()" will use the pathspec just to do some quick high-level pruning of the directories it will recurse into.
