2013-01-01Makefile: add USE_WILDMATCH to use wildmatch as fnmatchLibravatar Nguyễn Thái Ngọc Duy1-0/+3
This is similar to NO_FNMATCH but it uses wildmatch instead of compat/fnmatch. This is an intermediate step to let wildmatch be used as fnmatch replacement for wider audience before it replaces fnmatch completely and compat/fnmatch is removed. fnmatch in test-wildmatch is not impacted by this and is the only place that NO_FNMATCH or NO_FNMATCH_CASEFOLD remain active when USE_WILDMATCH is set.

2013-01-01test-wildmatch: add "perf" command to compare wildmatch and fnmatchLibravatar Nguyễn Thái Ngọc Duy1-0/+73
It takes a text file, a pattern, a number <n> and pathname flag. Each line in the text file is matched against the pattern <n> times. If "pathname" is given, FNM_PATHNAME is used. test-wildmatch is built with -O2 and tested against glibc 2.14.1 (also -O2) and compat/fnmatch. The input file is linux-2.6.git file list. <n> is 2000. The complete command list is at the end. wildmatch is beaten in the following cases. Apparently it needs some improvement in FNM_PATHNAME case: glibc, '*/*/*' with FNM_PATHNAME: wildmatch 8s 1559us fnmatch 1s 11877us or 12.65% faster compat, '*/*/*' with FNM_PATHNAME: wildmatch 7s 922458us fnmatch 2s 905111us or 36.67% faster compat, '*/*/*' without FNM_PATHNAME: wildmatch 7s 264201us fnmatch 2s 1897us or 27.56% faster compat, '[a-z]*/[a-z]*/[a-z]*' with FNM_PATHNAME: wildmatch 8s 742827us fnmatch 0s 922943us or 10.56% faster compat, '[a-z]*/[a-z]*/[a-z]*' without FNM_PATHNAME: wildmatch 8s 284520us fnmatch 0s 6936us or 0.08% faster The rest of glibc numbers ------------------------- 'Documentation/*' wildmatch 1s 529479us fnmatch 1s 98263us or 71.81% slower 'drivers/*' wildmatch 1s 988288us fnmatch 1s 192049us or 59.95% slower 'Documentation/*' pathname wildmatch 1s 557507us fnmatch 1s 93696us or 70.22% slower 'drivers/*' pathname wildmatch 2s 161626us fnmatch 1s 230372us or 56.92% slower '[Dd]ocu[Mn]entation/*' wildmatch 1s 776581us fnmatch 1s 471693us or 82.84% slower '[Dd]o?u[Mn]en?ati?n/*' wildmatch 1s 770770us fnmatch 1s 555727us or 87.86% slower '[Dd]o?u[Mn]en?ati?n/*' pathname wildmatch 1s 783507us fnmatch 1s 537029us or 86.18% slower '[A-Za-z][A-Za-z]??*' wildmatch 4s 110386us fnmatch 4s 926306us or 119.85% slower '[A-Za-z][A-Za-z]??' wildmatch 3s 918114us fnmatch 3s 686175us or 94.08% slower '[A-Za-z][A-Za-z]??*' pathname wildmatch 4s 453746us fnmatch 4s 955856us or 111.27% slower '[A-Za-z][A-Za-z]??' pathname wildmatch 3s 896646us fnmatch 3s 733828us or 95.82% slower '*/*/*' wildmatch 7s 287985us fnmatch 1s 74083us or 14.74% slower '[a-z]*/[a-z]*/[a-z]*' pathname wildmatch 8s 796659us fnmatch 1s 568409us or 17.83% slower '[a-z]*/[a-z]*/[a-z]*' wildmatch 8s 316559us fnmatch 3s 430652us or 41.25% slower The rest of compat numbers -------------------------- 'Documentation/*' wildmatch 1s 520389us fnmatch 0s 62579us or 4.12% slower 'drivers/*' wildmatch 1s 955354us fnmatch 0s 190109us or 9.72% slower 'Documentation/*' pathname wildmatch 1s 561675us fnmatch 0s 55336us or 3.54% slower 'drivers/*' pathname wildmatch 2s 106100us fnmatch 0s 219680us or 10.43% slower '[Dd]ocu[Mn]entation/*' wildmatch 1s 750810us fnmatch 0s 542721us or 31.00% slower '[Dd]o?u[Mn]en?ati?n/*' wildmatch 1s 724791us fnmatch 0s 538948us or 31.25% slower '[Dd]o?u[Mn]en?ati?n/*' pathname wildmatch 1s 731403us fnmatch 0s 537474us or 31.04% slower '[A-Za-z][A-Za-z]??*' wildmatch 4s 28555us fnmatch 1s 67297us or 26.49% slower '[A-Za-z][A-Za-z]??' wildmatch 3s 838279us fnmatch 0s 880005us or 22.93% slower '[A-Za-z][A-Za-z]??*' pathname wildmatch 4s 379476us fnmatch 1s 55643us or 24.10% slower '[A-Za-z][A-Za-z]??' pathname wildmatch 3s 830910us fnmatch 0s 849699us or 22.18% slower The following commands are used: LANG=C ./test-wildmatch perf /tmp/filelist.txt 'Documentation/*' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt 'drivers/*' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt 'Documentation/*' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt 'drivers/*' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt '[Dd]ocu[Mn]entation/*' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt '[Dd]o?u[Mn]en?ati?n/*' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt '[Dd]o?u[Mn]en?ati?n/*' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt '[A-Za-z][A-Za-z]??*' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt '[A-Za-z][A-Za-z]??' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt '[A-Za-z][A-Za-z]??*' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt '[A-Za-z][A-Za-z]??' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt '*/*/*' 2000 LANG=C ./test-wildmatch perf /tmp/filelist.txt '*/*/*' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt '[a-z]*/[a-z]*/[a-z]*' 2000 pathname LANG=C ./test-wildmatch perf /tmp/filelist.txt '[a-z]*/[a-z]*/[a-z]*' 2000 Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-01-01wildmatch: support "no FNM_PATHNAME" modeLibravatar Nguyễn Thái Ngọc Duy1-2/+4
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().

2013-01-01wildmatch: rename constants and update prototypeLibravatar Nguyễn Thái Ngọc Duy1-2/+2
- 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>
2012-11-20test-wildmatch: avoid Windows path manglingLibravatar Nguyễn Thái Ngọc Duy1-0/+8
The MSYS bash mangles arguments that begin with a forward slash when they are passed to test-wildmatch. This causes tests to fail. Avoid mangling by prepending "XXX", which is removed by test-wildmatch before further processing.

2012-10-15wildmatch: make wildmatch's return value compatible with fnmatchLibravatar Nguyễn Thái Ngọc Duy1-2/+2
wildmatch returns non-zero if matched, zero otherwise. This patch makes it return zero if matches, non-zero otherwise, like fnmatch(). Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
