2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker-1/+1
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2012-01-23make glob mark symlinks-to-directories with the GLOB_MARK flagRich Felker-1/+1
POSIX is unclear on whether it should, but all historical implementations seem to behave this way, and it seems more useful to applications.

2011-06-06fix handling of d_name in struct direntRich Felker-3/+2
basically there are 3 choices for how to implement this variable-size string member: 1. C99 flexible array member: breaks using dirent.h with pre-C99 compiler. 2. old way: length-1 string: generates array bounds warnings in caller. 3. new way: length-NAME_MAX string. no problems, simplifies all code. of course the usable part in the pointer returned by readdir might be shorter than NAME_MAX+1 bytes, but that is allowed by the standard and doesn't hurt anything.
2011-06-05safety fix for glob's vla usage: disallow patterns longer than PATH_MAXRich Felker-0/+2
this actually inadvertently disallows some valid patterns with redundant / or * characters, but it's better than allowing unbounded vla allocation. eventually i'll write code to move the pattern to the stack and eliminate redundancy to ensure that it fits in PATH_MAX at the beginning of glob. this would also allow it to be modified in place for passing to fnmatch rather than copied at each level of recursion.
