* Make the changes needed for libpthread to compile in its new home.Jonathan Mini2002-09-161-4/+4
| | | | | | | | | | | The new libpthread will provide POSIX threading support using KSE. These files were previously repo-copied from src/lib/libc_r. Reviewed by: deischen Approved by: -arch Notes: svn path=/head/; revision=103388

* Add weak definitions for wrapped system calls. In general:Daniel Eischen2001-01-241-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _foo - wrapped system call foo - weak definition to _foo and for cancellation points: _foo - wrapped system call __foo - enter cancellation point, call _foo(), leave cancellation point foo - weak definition to __foo Change use of global _thread_run to call a function to get the currently running thread. 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. Approved by: -arch Notes: svn path=/head/; revision=71581

* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),Jason Evans2000-01-271-1/+1
| | | | | | | | | | | | | | | | | | | | just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant.

* Use growable stacks for thread stacks that are the default stack size.Jason Evans1999-07-051-2/+5
| | | | | | | | | | | | | | | | Cache discarded default thread stacks for use in subsequent thread creations. Create a red zone at the end of each stack (including the initial thread stack), with the hope of causing a segfault if a stack overflows. To activate these modifications, add -D_PTHREAD_GSTACK to CFLAGS in src/lib/libc_r/Makefile. Since the modifications depend on the VM_STACK kernel option, I'm not sure how to safely use growable stacks by default. Testing, as well as algorithmic and stylistic comments are welcome.

* Add poll to the list of hidden syscalls so that it gets renamed. ThisJohn Birrell1998-06-121-2/+2
| | | | | | | | | | | | | | propagates a bug (that there is no poll wrapper in libc_r), but it prevents GNU configure scripts from trying to use it in preference to select. libc_r really needs to change it's wait interface to use poll instead of select because poll is more a superset of select that the other way around. This should allow the Roxen web server to work out-of-the-box. It's configuration intercae is kinda neat. The code isn't. Shiver. 8-) Notes: svn path=/head/; revision=36905

| | | | | | | | | | | | | Change MACHINE references to MACHINE_ARCH. Declare the names of the syscalls that need to be renamed to allow for the functions that libc_r provides replacements for. This list used to be in lib/libc/sys/Makefile.inc, but has been moved here to keep that makefile tidy and remove the temptation for people to add things to the list without adding a libc_r replacement function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here are the diffs for libc_r to get it one step closer to P1003.1c These make most of the thread/mutex/condvar structures opaque to the user. There are three functions which have been renamed with _np suffixes because they are extensions to P1003.1c (I did them for JAVA, which needs to suspend/resume threads and also start threads suspended). I've created a new header (pthread_np.h) for the non-POSIX stuff. The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented doesn't work. I think its best to delete it. I don't think libc_r needs tags anyway, 'cause most of the source is in libc which does have tags. also: Here's the first batch of man pages for the thread functions. The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was inherited from /usr/src/lib/libc/Makefile that should only be done with libc. also: I should have sent this diff with the pthread(3) man page. It allows people to type make -DWANT_LIBC_R world to get libc_r built with the rest of the world. I put this in the pthread(3) man page. The default is still not to build libc_r. also: The diff attached adds a pthread(3) man page to /usr/src/share/man/man3. The idea is that without libc_r installed, this man page will give people enough info to know that they have to build libc_r. Notes: svn path=/head/; revision=17706
