* Add code to support thread debugging.David Xu2004-07-1310-88/+292
| | | | | | | | | | | | | | | | | | 1. Add global varible _libkse_debug, debugger uses the varible to identify libpthread. when the varible is written to non-zero by debugger, libpthread will take some special action at context switch time, it will check TMDF_DOTRUNUSER flags, if a thread has the flags set by debugger, it won't be scheduled, when a thread leaves KSE critical region, thread checks the flag, if it was set, the thread relinquish CPU. 2. Add pq_first_debug to select a thread allowd to run by debugger. 3. Some names prefixed with _thr are renamed to _thread prefix. which is allowed to run by debugger.

* Make regular expression matching aware of multibyte characters. The generalTim J. Robbins2004-07-125-324/+478
| | | | | | | | | | | | | | | | | | | | idea is that we perform multibyte->wide character conversion while parsing and compiling, then convert byte sequences to wide characters when they're needed for comparison and stepping through the string during execution. As with tr(1), the main complication is to efficiently represent sets of characters in bracket expressions. The old bitmap representation is replaced by a bitmap for the first 256 characters combined with a vector of individual wide characters, a vector of character ranges (for [A-Z] etc.), and a vector of character classes (for [[:alpha:]] etc.). One other point of interest is that although the Boyer-Moore algorithm had to be disabled in the general multibyte case, it is still enabled for UTF-8 because of its self-synchronizing nature. This greatly speeds up matching by reducing the number of multibyte conversions that need to be done. Notes: svn path=/head/; revision=132019
* Add a new error code, REG_ILLSEQ, to indicate that a regular expressionTim J. Robbins2004-07-122-1/+5

* Implement the classification macros isfinite(), isinf(), isnan(), andDavid Schultz2004-07-0921-508/+287
| | | | | | | | | | | | | | | | | | | | | | | | isnormal() the hard way, rather than relying on fpclassify(). This is a lose in the sense that we need a total of 12 functions, but it is necessary for binary compatibility because we have never bumped libm's major version number. In particular, isinf(), isnan(), and isnanf() were BSD libc functions before they were C99 macros, so we can't reimplement them in terms of fpclassify() without adding a dependency on libc.so.5. I have tried to arrange things so that programs that could be compiled in FreeBSD 4.X will generate the same external references when compiled in 5.X. At the same time, the new macros should remain C99-compliant. The isinf() and isnan() functions remain in libc for historical reasons; however, I have moved the functions that implement the macros isfinite() and isnormal() to libm where they belong. Moreover, half a dozen MD versions of isinf() and isnan() have been replaced with MI versions that work equally well. Prodded by: kris Notes: svn path=/head/; revision=131852
* Define the following macros in terms of [gi]cc builtins when theDavid Schultz2004-07-091-0/+29
| | | | | | | | | | | | | | | | | | | | | builtins are available: HUGE_VAL, HUGE_VALF, HUGE_VALL, INFINITY, and NAN. These macros now expand to floating-point constant expressions rather than external references, as required by C99. Other compilers will retain the historical behavior. Note that it is not possible say, e.g. #define HUGE_VAL 1.0e9999 because the above may result in diagnostics at translation time and spurious exceptions at runtime. Hence the need for compiler support for these features. Also use builtins to implement the macros isgreater(), isgreaterequal(), isless(), islessequal(), islessgreater(), and isunordered() when such builtins are available. Although the old macros are correct, the builtin versions are much faster, and they avoid double-expansion problems. Notes: svn path=/head/; revision=131851
* Eliminate some magic numbers and correct description of _PC_NO_TRUNC.Garrett Wollman2004-07-082-20/+45

* Add a function to iterate over all characters in a particular characterTim J. Robbins2004-07-083-2/+150
| | | | | | | | | class. This is necessary in order to implement tr(1) efficiently in multibyte locales, since the brute force method of finding all characters in a class is infeasible with a 32-bit (or wider) wchar_t. Notes: svn path=/head/; revision=131787
* I think this is my fourth complete rewrite of the dir-creationTim Kientzle2004-07-081-139/+213
| | | | | | | | | | | | | | | | | | code. <whew!> This version handles all of the following edge cases: * Restoring explicit dirs with 000 permissions (star fails this test) * Restore of implicit or explicit dirs when umask=777 (gtar and star both fail this test) * Restoring dir paths containing "." and ".." components This version initially creates all dirs with permission 700 (ignoring umask), then does a post-extract "fixup" pass to set the correct permissions (which may or may not depend on umask, depending on the restore flags and whether it's an explicit or implicit dir). Permissions are restored depth-first so that permissions within non-writable dirs can be correctly restored. (The depth-sorting does correctly account for dirs with ".." components.)
