* Fix the problems I (and others, undoubtedly) have been having for aBrian Feldman2001-02-231-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | while with threaded software in -CURRENT acting very "weird". It has seemed, for example, in Mozilla that threads attempting to do host lookups have been locking up. That's exactly the case. There was a race condition in the implementation of the initialization of the mutex used to protect FILE operations, first of all: multiple instances of FLOCKFILE() in libc could occur on the same FILE at the same time and cause strange behavior by overwriting eachothers' creation of the mutex and the rest of the file lock. Secondly, it's not appropriate to test the "validity" of the file descriptor referenced by the FILE; if the code is calling FLOCKFILE() or FUNLOCKFILE(), it wants the FILE to be locked or unlocked, not to be locked or unlocked on the condition that _file is >= 0. This also could quite easily cause leaks by failing to perform the lock or unlock operation when it actually is needed. Mozilla now works again on -CURRENT when linked to libc_r.so.5 and libc.so.5.

* Place some hooks (__stdin, __stdout, __stderr) into libc for a futurePeter Wemm2001-02-201-0/+23
| | | | | | | | | | | | | | ABI change. There is some serious evilness here to work around some gcc weaknesses. We need to know the sizeof(FILE) manually until __sF goes away in the next major bump. We have the size for Alpha and i386, missing is ia64, ppc and sparc* (and i386 with 64 bit longs). At some point down the track we can change the stdin etc #defines to stop hard coding the size of FILE into application binaries.

* Commit a libc fix going by the current state of the version numberingPeter Wemm2001-02-141-9/+10
| | | | | | | | | | | | | | | | | | | bikeshed in -arch. It isn't quite over, but it has been well established that this can be adjusted or refined. But we do seem to have consensis on a major bump of some sort. After this, it should reasonably safe to build world again. This change is to get rid of __sF[] and use seperate __stdin/out/err handles. This means we can pad on extra bits onto the end of FILE at will without going through this all over again. __sF[] was evil because it compiled the sizeof(FILE) into every stdio using program.

The __stdin stuff is there to not pollute application name space if the application does not use <stdio.h> and also in case something depended on the current behavior where stdin etc was a #define.

* libc MT-safety, part 2.Daniel Eischen2001-02-1119-102/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a lock to FILE. flockfile and friends are now implemented (for the most part) in libc. flockfile_debug is implemented in libc_r; I suppose it's about time to kill it but will do it in a future commit. Fix a potential deadlock in _fwalk in a threaded environment. A file flag (__SIGN) was added to stdio.h that, when set, tells _fwalk to ignore it in its walk. This seemed to be needed in refill.c because each file needs to be locked when flushing. Add a stub for pthread_self in libc. This is needed by flockfile which is allowed by POSIX to be recursive. Make fgetpos() error return value (-1) match man page. Remove recursive calls to locked functions (stdio); I think I've got them all, but I may have missed a couple.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579

| | | | | | | | | | | | | | | | | | | | 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.

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.
