* fix bug that would leave an FD locked if dup'd, then closed.marc2003-02-141-5/+23
| | | | Also, for safety lock the _thread_fd_table when removing entries.
* AARRGGH! 2nd try, handle the case where from_fd == to_fd in _thread_fd_table_dupmarc2003-02-051-2/+2

* thread fd handling, part 2. Don't mung file flags until forcedmarc2003-02-051-11/+15
| | | | | | | | 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_entriesmarc2003-02-041-21/+127
| | | | | | | | | | | | | | | | | 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
* return (func(...)) not needed when the current function and funcmarc2003-01-191-3/+2

* removes duplicate functions and factor out common code so the needed (butmarc2002-10-301-463/+222
| | | | | | | | missing) _thread_fd_unlock_owned function can be added with minimal pain. The incorrect special handling of the stdio fds was also removed. Tested with the libc_r regression tests and the mysql regression tests. No complaints from any developers

* Start syncing with FreeBSD:fgsch2001-08-211-25/+29
| | | | | | | | | | o Implement _get_curthread() and _set_curthread(). Use it where possible. o Add missing _thread_[enter|leave]_cancellation_point(). o Add a couple of not yet used vars to pthread_private.h. o Remove return's from void functions. This is by no means complete, but instead of doing a big commit, i'll split it in small ones, minimizing diffs.
