2012-05-05drop support for old systems lacking vforkMark Salter
Only really old systems (<=linux-2.0) lack a dedicated vfork system call. The code that is in place to support them is causing issues with newer arches that also don't provide a vfork system call -- instead, they do vfork by calling clone in userspace. If anyone cares about these really old systems, they can submit a patch to make the system work with them while not breaking newer systems.

2006-12-07Major cleanup of internal mutex locking. Be more consistant in how we doEric Andersen
things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.

2004-02-11New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III
Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.
2004-01-02Oops... temporarily support the old stdio code.Manuel Novoa III
2004-01-02Rewrite popen for SUSv3 compliance.Manuel Novoa III
Added a list of popen()'d to store pids and use waitpid() in pclose(). Loop on waitpid() failure due to EINTR as required. Close parent's popen()'d FILEs in the {v}fork()'d child. Fix failure exit code for failed execve().
2002-12-01If the wait failed in pclose it would return a random status codeDavid McCullough
instead of -1 as expected.
2002-07-31Per discussion on the mailing list, simply vfork -> fork mapping to only applyEric Andersen
iff we do not have vfork available, which is simpler and more reasonable. -Erik
2002-06-11A patch from Ted Phelps to fix popen(). Ted writes:Eric Andersen
There is a minor bug in the implementation of popen(). In the case where the file descriptor returned from its call to pipe() is the same as the file descriptor that it is meant to be (where the dup2() branch is not taken), the end of the pipe is still closed by close(reading) even though it shouldn't be. Thanks Ted!

2001-04-06Fix include/errno.h to not use kernel header, and instead use bits/errno.h.Eric Andersen
This required we use _LIBC instead of __LIBC__ to be consistent with glibc. This had some sideffects in sys/syscalls.h. While fixing things, I made everything use __set_errno() for (eventual) thread support. -Erik
