Nguyễn Thái Ngọc Duy	6f1a31f0aa	wildmatch: advance faster in <asterisk> + <literal> patterns Normally when we match "X" on "abcX", we call dowild("X", "abcX"), dowild("X", "bcX"), dowild("X", "cX") and dowild("X", "X"). Only the last call may have a chance of matching. By skipping the text before "X", we can eliminate the first three useless calls. compat, '//' on linux-2.6.git file list 2000 times, before: wildmatch 7s 985049us fnmatch 2s 735541us or 34.26% faster and after: wildmatch 4s 492549us fnmatch 0s 888263us or 19.77% slower Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Nguyễn Thái Ngọc Duy	46983441ae	wildmatch: make a special case for "/" with FNM_PATHNAME Normally we need recursion for "". In this case we know that it matches everything until "/" so we can skip the recursion. glibc, '//*' on linux-2.6.git file list 2000 times before: wildmatch 8s 74513us fnmatch 1s 97042us or 13.59% faster after: wildmatch 3s 521862us fnmatch 3s 488616us or 99.06% slower Same test with compat/fnmatch: wildmatch 8s 110763us fnmatch 2s 980845us or 36.75% faster wildmatch 3s 522156us fnmatch 1s 544487us or 43.85% slower Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Nguyễn Thái Ngọc Duy	c41244e702	wildmatch: support "no FNM_PATHNAME" mode So far, wildmatch() has always honoured directory boundary and there was no way to turn it off. Make it behave more like fnmatch() by requiring all callers that want the FNM_PATHNAME behaviour to pass that in the equivalent flag WM_PATHNAME. Callers that do not specify WM_PATHNAME will get wildcards like ? and * in their patterns matched against '/', just like not passing FNM_PATHNAME to fnmatch().

Nguyễn Thái Ngọc Duy	b6a3d3353f	wildmatch: replace variable 'special' with better named ones 'special' is too generic and is used for two different purposes. Replace it with 'match_slash' to indicate "**" pattern and 'negated' for "[!...]" and "[^...]".

Nguyễn Thái Ngọc Duy	9b3497cab9	wildmatch: rename constants and update prototype - All exported constants now have a prefix WM_ - Do not rely on FNM_* constants, use the WM_ counterparts - Remove TRUE and FALSE to follow Git's coding style - While at it, turn flags type from int to unsigned int - Add an (unused yet) argument to carry extra information so that we don't have to change the prototype again later when we need to pass other stuff to wildmatch Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Nguyễn Thái Ngọc Duy	3a078dec33	wildmatch: fix "" special case "" is adjusted to only be effective when surrounded by slashes, in `40bbee0` (wildmatch: adjust "" behavior - 2012-10-15). Except that the commit did it wrong: 1. when it checks for "the preceding slash unless is at the beginning", it compares to wrong pointer. It should have compared to the beginning of the pattern, not the text. 2. prev_p points to the character before "*", not the first "". The correct comparison must be "prev_p < pattern" or "prev_p + 1 == pattern", not "prev_p == pattern". 3. The pattern must be surrounded by slashes unless it's at the beginning or the end of the pattern. We do two checks: one for the preceding slash and one the trailing slash. Both checks must be met. The use of "\|\|" is wrong. This patch fixes all above. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Nguyễn Thái Ngọc Duy	4c251e5cb5	wildmatch: make // match zero or more directories "foo//bar" matches "foo/x/bar", "foo/x/y/bar"... but not "foo/bar". We make a special case, when foo/*/ is detected (and "foo/" part is already matched), try matching "bar" with the rest of the string. "Match one or more directories" semantics can be easily achieved using "foo///bar". This also makes "/foo" match "foo" in addition to "x/foo", "x/y/foo"..

Nguyễn Thái Ngọc Duy	40bbee0ab0	wildmatch: adjust "*" behavior Standard wildmatch() sees consecutive asterisks as "" that can also match slashes. But that may be hard to explain to users as "abc//def" can match "abcdef", "abcxyzdef", "abc/def", "abc/x/def", "abc/x/y/def"... This patch changes wildmatch so that users can do - "/def" -> all paths ending with file/directory 'def' - "abc/" - equivalent to "/abc/" - "abc//def" -> "abc/x/def", "abc/x/y/def"... - otherwise consider the pattern malformed if "" is found Basically the magic of "" only remains if it's wrapped around by slashes.

Nguyễn Thái Ngọc Duy	164bf83af6	wildmatch: fix case-insensitive matching dowild() does case insensitive matching by lower-casing the text. That means lower case letters in patterns imply case-insensitive matching, but upper case means exact matching. We do not want that subtlety. Lower case pattern too so iwildmatch() always does what we expect it to do. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago

Nguyễn Thái Ngọc Duy	327f2f3ebb	wildmatch: follow Git's coding convention wildmatch's coding style is pretty close to Git's except the use of 4 space indentation instead of 8.
