This commit was manufactured by cvs2svn to create tag

'RELENG_4_1_0_RELEASE'.

This commit was manufactured to restore the state of the 4.1-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Use __strong_reference() instead of __weak_reference() to assure that the

2000-01-29T22:53:55+00:00

weak symbols of the same name are not used.

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25+00:00

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.

Track libc's three-tier symbol naming. libc_r must currently implement

2000-01-12T09:28:58+00:00

the _libc_*() entry points and add *() weak aliases.  This will all
change for the better when libc_r becomes libpthread.

General clean-up of socket.h and associated sources to synchronise up

1999-11-24T20:49:04+00:00

with NetBSD and the Single Unix Specification v2.

This updates some structures with other, almost equivalent types and
effort is under way to get the whole more consistent.

Also removes a double definition of INET6 and some other clean-ups.

Implement compile time debug support instead of tracking file name and

1998-06-09T23:21:05+00:00

line number every time a file descriptor is locked.

This looks like a big change but it isn't. It should reduce the size
of libc_r and make it run slightly faster.

Change signal model to match POSIX (i.e. one set of signal handlers

1998-04-29T09:59:34+00:00

for the process, not a separate set for each thread). By default, the
process now only has signal handlers installed for SIGVTALRM, SIGINFO
and SIGCHLD. The thread kernel signal handler is installed for other
signals on demand. This means that SIG_IGN and SIG_DFL processing is now
left to the kernel, not the thread kernel.

Change the signal dispatch to no longer use a signal thread, and
call the signal handler using the stack of the thread that has the
signal pending.

Change the atomic lock method to use test-and-set asm code with
a yield if blocked. This introduces separate locks for each type
of object instead of blocking signals to prevent a context
switch. It was this blocking of signals that caused the performance
degradation the people have noted.

This is a *big* change!
