2012-03-20upgrade to latest upstream TRE regex code (0.8.0)Rich Felker5-1168/+1037
the main practical results of this change are 1. the regex code is no longer subject to LGPL; it's now 2-clause BSD 2. most (all?) popular nonstandard regex extensions are supported I hesitate to call this a "sync" since both the old and new code are heavily modified. in one sense, the old code was "more severely" modified, in that it was actively hostile to non-strictly-conforming expressions. on the other hand, the new code has eliminated the useless translation of the entire regex string to wchar_t prior to compiling, and now only converts multibyte character literals as needed. in the future i may use this modified TRE as a basis for writing the long-planned new regex engine that will avoid multibyte-to-wide character conversion entirely by compiling multibyte bracket expressions specific to UTF-8.
2012-01-23make glob mark symlinks-to-directories with the GLOB_MARK flagRich Felker1-1/+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 Felker1-3/+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 Felker1-0/+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.
