This commit was manufactured to restore the state of the 5.4-RELEASE image. Rename _thr_enter_cancellation_point to _thr_cancel_enter, rename 2003-12-09T02:20:56Z David Xu davidxu@FreeBSD.org 2003-12-09T02:20:56Z urn:sha1:71679e629d6933bda40564da2a54894aed1358f3 _thr_leave_cancellation_point to _thr_cancel_leave, add a parameter to _thr_cancel_leave to indicate whether cancellation point should be checked, this gives us an option to not check cancallation point if a syscall successfully returns to avoid any leaks, current I have creat(), open() and fcntl(F_DUPFD) to not check cancellation point after they sucessfully returned. Replace some members in structure kse with bit flags to same some memory. Conditionally compile THR_ASSERT to nothing if _PTHREAD_INVARIANTS is not defined. Inline some small functions in thr_cancel.c. Use __predict_false in thr_kern.c for some executed only once code. Reviewd by: deischen Revamp libpthread so that it has a chance of working in an SMP 2003-04-18T05:04:16Z Daniel Eischen deischen@FreeBSD.org 2003-04-18T05:04:16Z urn:sha1:a0240e2cb0b1ef8e5b61930ac2b850c884daaba8 environment. This includes support for multiple KSEs and KSEGs. The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.

Make all pthread_foo functions weak definitions to _pthread_foo, where _pthread_foo is the implementation. This allows an application to provide its own pthread functions. Provide slightly different versions of pthread_mutex_lock and pthread_mutex_init so that we can tell the difference between a libc mutex and an application mutex. Threads holding mutexes internal to libc should never be allowed to exit, call signal handlers, or cancel.
