From: Adam Spiers <git@xxxxxxxxxxxxxx> The excluded function uses a new helper function called last_exclude_matching_from_list() to perform the inner loop over all of the exclude patterns. The helper just tells us whether the path is included, excluded, or undecided. However, it may be useful to know _which_ pattern was triggered. So let's pass out the entire exclude match, which contains the status information we were already passing out. Further patches can make use of this. This is a modified forward port of a patch from 2009 by Jeff King: http://article.gmane.org/gmane.comp.version-control.git/108815 Signed-off-by: Adam Spiers <git@xxxxxxxxxxxxxx> Signed-off-by: Junio C Hamano <gitster@xxxxxxxxx> Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@xxxxxxxxx> --- dir.c | 37 ++++++++++++++++++++++++++++--------- 1 file changed, 28 insertions(+), 9 deletions(-) diff --git a/dir.c b/dir.c index 50381f8..859e0f9 100644 --- a/dir.c +++ b/dir.c @@ -596,22 +596,26 @@ int match_pathname(const char *pathname, int pathlen, return fnmatch_icase(pattern, name, FNM_PATHNAME) == 0; } -/* Scan the list and let the last match determine the fate. - * Return 1 for exclude, 0 for include and -1 for undecided. +/* + * Scan the given exclude list in reverse to see whether pathname + * should be ignored.
