* Add a new "non-portable" mutex type, PTHREAD_MUTEX_ADAPTIVE_NP. ThisKris Kennaway2007-10-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is also implemented in glibc and is used by a number of existing applications (mysql, firefox, etc). This mutex type is a default mutex with the additional property that it spins briefly when attempting to acquire a contested lock, doing trylock operations in userland before entering the kernel to block if eventually unsuccessful. The expectation is that applications requesting this mutex type know that the mutex is likely to be only held for very brief periods, so it is faster to spin in userland and probably succeed in acquiring the mutex, than to enter the kernel and sleep, only to be woken up almost immediately. This can help significantly in certain cases when pthread mutexes are heavily contended and held for brief durations (such as mysql). Spin up to 200 times before entering the kernel, which represents only a few us on modern CPUs. No performance degradation was observed with this value and it is sufficient to avoid a large performance drop in mysql performance in the heavily contended pthread mutex case. The libkse implementation is a NOP. Reviewed by: jeff MFC after: 3 days Notes: svn path=/head/; revision=173154

* The problem is: currently our single byte ctype(3) functions are brokenAndrey A. Chernov2007-10-133-23/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | for wide characters locales in the argument range >= 0x80 - they may return false positives. Example 1: for UTF-8 locale we currently have: iswspace(0xA0)==1 and isspace(0xA0)==1 (because iswspace() and isspace() are the same code) but must have iswspace(0xA0)==1 and isspace(0xA0)==0 (because there is no such character and all others in the range 0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte range because our internal wchar_t representation for UTF-8 is UCS-4). Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may return false positives (must be 0). (because iswalpha() and isalpha() are the same code) This change address this issue separating single byte and wide ctype and also fix iswascii() (currently iswascii() is broken for arguments > 0xFF). This change is 100% binary compatible with old binaries. Reviewied by: i18n@ Notes: svn path=/head/; revision=172619

* Significantly reduce the memory leak as noted in BUGS section forSean Farley2007-07-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

* Update the dump program to save extended attributes. UpdateKirk McKusick2007-02-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the restore program to restore all dumped extended attributes. If the restore is running as root, it will always be able to restore all extended attributes. If it is not running as root, it makes a best effort to set them. Using the -v command line flag or the `verbose' command in interactive mode will display all the extended attributes being set on files (and at the end on directories) that are being restored. It will note any extended attributes that could not be set. The extended attributes are placed on the dump image immediately following each file's data. Older versions of restore can work with the newer dump images. Old versions of restore will correctly restore the file data and then (silently) skip over the extended attribute data and proceed to the next file. This resolves PR 93085 which will be closed once the code has been MFC'ed. Note that this code will not compile until these header files have been updated: <protocols/dumprestore.h> and <sys/extattr.h>.

* Attempt to improve application portability by marking `struct ar_hdr'Joseph Koshy2006-11-131-1/+5
| | | | | | | | | | | | | | | | as `packed'. The C standard leaves the alignment of individual members of a C struct upto the implementation, so pedantically speaking portable code cannot assume that the layout of a `struct ar_hdr' in memory will match its layout in a file. Using a __packed attribute declaration forces file and memory layouts for this structure to match. Submitted by: ru Notes: svn path=/head/; revision=164244
