win32: bug fix in fnmatch(3)

2022-06-23T15:05:17+00:00

A user reports: Here is the shell script that causes me problems: var=foo:bar echo ${var#*[[:space:]]} What expect I to see echoed is foo:bar, however what I see bar. It seems that the [[:space:]] character class is matching the colon character in addition to whitespace characters. I see the same problem with the [[:blank:]] character class. This is due to a bug in the WIN32 implementation of fnmatch(3) which is derived from an old snapshot of glibc code (glibc commit 7814856974 from 1999-09-12). The bug was fixed in glibc by commit 83b1b6d8fa of 2000-07-04. Apply the equivalent fix to our version.

win32: code shrink character class detection

2021-08-09T13:58:37+00:00

Add a routine to detect the names of character classes. Use it in fnmatch(3) and regcomp(3), replacing local code in the former. Saves 216 bytes.

win32: fix fnmatch(3) handling of xdigit

2021-08-09T13:41:48+00:00

The glob pattern '[[:xdigit::]]*' didn't return the matches expected. It turns out the implementation (from glibc) fails to detect 'xdigit' as a valid character class. Changing the definition of CHAR_CLASS_MAX_LENGTH to 7 fixes the problem. This was never an issue in glibc because it uses a different definition. More modern versions of fnmatch(3) in glibc and gnulib also make CHAR_CLASS_MAX_LENGTH long enough. The code for fnmatch(3) was taken from glibc at commit 7814856974388a856a575fa45f88d502c8a1ab29. This was the last version before the code was rearraged to better support multibyte characters.

win32: save bytes in fnmatch

2020-02-16T09:56:04+00:00

Replace several explicit string comparisons with a single call to index_in_strings(). Saves 304 bytes.

win32: use strchrnul from BusyBox in fnmatch

2018-03-05T14:33:51+00:00

BusyBox ensures that strchrnul is always available, either from the target platform or by including its own version. Therefore it isn't necessary for fnmatch to use its equivalent.

win32/fnmatch: fix old-style function declaration

2017-08-23T11:56:21+00:00

It would be more straight-forward to simply #include "libbb.h" which includes a #define getenv mingw_getenv, but that header also defines isprint() to a function that is nowhere to be found, leading to link problems. So let's go the easy route. Signed-off-by: Johannes Schindelin Signed-off-by: Ron Yorston
