* Remove some double semicolons (hmm, do two semis equal a maxi?).millert2003-08-061-5/+5
| | | | I've skipped the GNU stuff for now. From Patrick Latifi.
* Go back to using ITIMER_PROF for the non-profiled libpthread and usemillert2003-08-011-2/+2
| | | | | | | ITIMER_VIRTUAL for the profiled version. Fixes problems when programs linked with libpthread try to use ITIMER_VIRTUAL (and have no way of knowing that this will cause conflicts with the threads lib). marc@ OK

| | | | | | | | non-thread-safe dl functions. Only enabled for ELF architectures at this time as needed dlxxx support has not yet been added to the a.out run time loader. 'doesn't break xmms at least' tedu@. Tested by others with no comment

* Remove unused file. OpenBSD uses uthread_info_openbsd.c, instead.marc2003-03-311-317/+0
| | | | This is easier than fixing the strcpy in the file.

* thread fd handling, part 2. Don't mung file flags until forcedmarc2003-02-053-15/+25
| | | | | | | | to notice that the file exists. This fixes a problem where an application may think a file was in non-block mode because the threads kernel played with the flags. Also fix a stupid error introduced in the last commit -- the threaded version of dup and dup2 were foobared. Bad marc.
* Part 1 of thread fd handling fixes. In the new scheme fd_table_entriesmarc2003-02-047-368/+325
| | | | | | | | | | | | | | | | | for dup-ed fds are shared to ensure proper flag handling. A refcnt was added to control when entries should be freed. Specific changes: close: don't free entry unless refcnt is zero dup: rewrite to use new function _thread_fd_table_dup dup2: rewrite to use new function _thread_fd_table_dup fcntl: use _thread_fd_table_dup uthread_fd: initialize thread fd table, searching for dup-ed fds. Add function to share _thread_fd_table entries when an fd is dup-ed. uthread_init: make it readable. Call fd init functions. All current regression tests plus the mysql torture test pass. The new stdfiles regression test fails (I/O redirection problem). Part 2 is intended to fix that problem

* Create a siginfo_t for thread-to-thread kill.marc2003-01-3115-168/+97
| | | | | Clean up (compiler warning elimination). Compile check options added but commented out as they have not been checked on all architectures, yet.
* pthreads signal handling improvements. With these changes allmarc2003-01-277-383/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of the thread regressions tests pass on i386, sparc, sparc64 (save the siginfo test on sparc64 due to a kernel issue) and alpha. The tests should also pass on ppc. In addition, it fixes the problems with the "mysql torture test" provided by one of our users. The python port also appears to work correctly with these changes. Summary of changes: * check_pending removed from thread structure, no longer used. * unused elements of sigstatus structure removed. The sigstatus structure is now used to keep track of siginfo data instead of defining a local array in uthread_sig.c. * _thread_kern_sched_sig removed * _thread_sig_process goes away -- can't have a lock active when signal handlers are called. Functions now call _thread_sig_handle directly. * _thread_clear_pending now used lib wide to clear pending flags. It was named _clean_pending_flag and only used in uthread_sig.c. The function clears both per thread signals, and per process signals. * _thread_sig_handle now returns a value. * unused debugging macros removed from the thread kernel * dispatch pending signals after switching to a thread providing that signal handling hasn't been deferred by the thread. * process thread switchhooks before dispatching pending sigs * check for thread cancellation before dispatching pending sigs * re-wrote pthread-kill to do the correct thing. It now does minimal thread-kill-specific processing and then calls the existing code in uthread_sig to process the generated signal. * shut the compiler up when compiling uthread_mutex.c * no more "signal_lock". It does more harm than good. * keep track of "per-process" signals. * don't bother saving siginfo_t data for the scheduling signal. * per posix: SIGSTOP cleared when SIGCONT received and vice versa. * add _dispatch_signal to properly dispatch a signal to a thread. It sets the appropriate signal mask, something that was missing in the previous implementation. This fixes several bugs. The previous method held a lock. If the signal handler longjmp-ed the lock was never cleared and no more signals were processed.
* save and restore fp state when switching threads. This, withmarc2003-01-243-77/+46
| | | | | | | | | | | an arch/i386 patch previously commited and arch/sparc64 patches from jason@ make the preemption_float test pass on those two architectures. Do not run signal handlers for a thread until the thread has been made current, ensuring the proper context. Solves several (if not all) of the '_pq_insert_tail: Already in priority queue' problems.
