* wildmatch: remove unused wildopts parameterab/wildmatchÆvar Arnfjörð Bjarmason2017-06-231-2/+1
| | | | | | | | | | | | | | | Remove the unused wildopts placeholder struct from being passed to all wildmatch() invocations, or rather remove all the boilerplate NULL parameters. This parameter was added back in commit 9b3497cab9 ("wildmatch: rename constants and update prototype", 2013-01-01) as a placeholder for future use. Over 4 years later nothing has made use of it, let's just remove it. It can be added in the future if we find some reason to start using such a parameter.

* wildmatch: properly fold case everywhereAnthony Ramine2013-06-021-0/+7
| | | | | | | | | | | | | | | | | | | Case folding is not done correctly when matching against the [:upper:] character class and uppercased character ranges (e.g. A-Z). Specifically, an uppercase letter fails to match against any of them when case folding is requested because plain characters in the pattern and the whole string are preemptively lowercased to handle the base case fast. That optimization is kept and ISLOWER() is used in the [:upper:] case when case folding is requested, while matching against a character range is retried with toupper() if the character was lowercase, as the bounds of the range itself cannot be modified (in a case-insensitive context, [A-_] is not equivalent to [a-_]).

* wildmatch: advance faster in <asterisk> + <literal> patternsNguyễn Thái Ngọc Duy2013-01-011-0/+23
| | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | 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>
* wildmatch: support "no FNM_PATHNAME" modeNguyễn Thái Ngọc Duy2013-01-011-4/+9
| | | | | | | | | | | | 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().

* wildmatch: rename constants and update prototypeNguyễn Thái Ngọc Duy2013-01-011-45/+43
| | | | | | | | | | | | | - 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>
* wildmatch: replace variable 'special' with better named onesNguyễn Thái Ngọc Duy2013-01-011-9/+9
| | | | | | | | | 'special' is too generic and is used for two different purposes. Replace it with 'match_slash' to indicate "**" pattern and 'negated' for "[!...]" and "[^...]". Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* wildmatch: fix "**" special caseNguyễn Thái Ngọc Duy2013-01-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | "**" 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>
* wildmatch: make /**/ match zero or more directoriesNguyễn Thái Ngọc Duy2012-10-151-0/+12
| | | | | | | | | | | | | | | | "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"..

* wildmatch: adjust "**" behaviorNguyễn Thái Ngọc Duy2012-10-151-6/+7
| | | | | | | | | | | | | | | | | | | | 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.

* wildmatch: fix case-insensitive matchingNguyễn Thái Ngọc Duy2012-10-151-0/+2
| | | | | | | | | | | | 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>
