wiz 7a7ee80bcc Misc fixes from jmc@openbsd. 2003-05-10 12:24:54 +00:00
wiz 472351e13d Use
.In header.h
instead of
.Fd #include \*[Lt]header.h\*[Gt]
Much easier to read and write, and supported by groff for ages.
Okayed by ross.

kleink c02f38cf64 Warn if the old unsetenv() is referenced. 2003-04-13 17:39:13 +00:00
kleink aa92e94d2a Observed in other places: move __unsetenv13.c near unsetenv.c, only
group name space wrappers separately.

drochner 1a9947a7d7 unsetenv(3) returns "int" now 2003-04-07 16:29:06 +00:00
drochner 22b67837d4 compile unsetenv(3) into libc or you'll mess up your system 2003-04-07 16:22:43 +00:00
kleink 13dee93fb3 1003.1-2001 has introduced unsetenv() which differs from the current
implementation in not permitting a "name=value" argument.
* Add a conforming __unsetenv13() and do function renaming for
  unsetenv(); preserve old symbol with old behavior.
* Make visible setenv() and unsetenv() for 1003.1-2001 feature selection
  macros; resolves PR standards/20479.

nathanw aa70f03b23 When implementing a recursive mutex, it helps if you remember to
decrement the recursion count.

Fixes the problem of uic dying with a no-next-thread assertion while
building kdeadmin3; reported by Perry Metzger and others on
tech-pkg.
2003-03-19 22:26:47 +00:00
nathanw f60f35f3ab Don't acquire __environ_lock around exec*() calls; nothing requires
that these calls be thread-safe with respect to the environment, and it
causes serious problems for threaded applications which call vfork() and
exec*() (including indirectly, via popen() or system()).

Acquire and release __environ_lock in the parent in popen() and system() to
play safe and provide the child with a stable environment.

__environ_lock should also have an atfork() handler; still under development.

thorpej 65ec6ba6e7 Fix lib/20558:
A dynamically linked program invokes the rtld cleanup routine via
an atexit handler.  This rtld cleanup routine invokes _fini() for
shared libraries, which in-turn invoke __cxa_finalize() with their
DSO handle.  By luck, this happens to work okay for non-threaded
programs, but for a threaded program, this leads to deadlock (sometimes
manifested as an assertion failure, if the program didn't actually
create any threads).

Fixed by teaching __cxa_finalize() that it can be recursively invoked,
adjusting the handler list manipulation accordingly.

bjh21 22ebd2b34b Add _Exit(), for C99 and POSIX-2001.
Proposed on tech-userlevel to a resounding silence in April last year.
2003-03-01 15:59:02 +00:00
thorpej 26be93fa6f Rewrite atexit(3), and add support for __cxa_atexit()/__cxa_finalize(),
as specified by the C++ ABI for Itanium.  Despite the ABI document's name,
many of the items in it are implemented for other architectures.

See the following URL for a reference:

	http://www.codesourcery.com/cxx-abi/abi.html#dso-dtor

Fixes lib/18379 (from Joel Baker).
