utility functions which convert between string namespace names and
numeric constants used by the interface. Right now, two namespaces
are supported, EXTATTR_NAMESPACE_SYSTEM ("system") and
EXTATTR_NAMESPACE_USER ("user"). These functions are used by
various userland EA utilities, rather than hard coding the routines
all over the place.

_posix1e or _POSIX1E, removing them from the application namespace (and

We have been running this patch on a production NIS server for 2.5 weeks now.
Normally we would have ypserv die at least once a week, and often many times
a day.
This patch treats and error from select as zeroing out the FD_SET to indicate
that no fds are ready for reading. This is safe because the rpc code
always re-inits the FDSET before calling select.
The below text is quoted from the latest POSIX draft:
: The values of locale categories shall be determined by a precedence
: order; the first condition met below determines the value:
:
: 1. If the LC_ALL environment variable is defined and is not null,
: the value of LC_ALL shall be used.
: 2. If the LC_* environment variable (LC_COLLATE, LC_CTYPE, LC_MESSAGES,
: LC_MONETARY, LC_NUMERIC, LC_TIME) is defined and is not null, the
: value of the environment variable shall be used to initialize the
: category that corresponds to the environment variable.
: 3. If the LANG environment variable is defined and is not null, the
: value of the LANG environment variable shall be used.
: 4. If the LANG environment variable is not set or is set to the empty
: string, the implementation-defined default locale shall be used.
The conditions 1 and 2 were interchanged, i.e., LC_* were looked first,
then LC_ALL, then LANG (note that LC_ALL and LANG were essentially the
same, providing the default, with LC_ALL taking precedence over LANG).
Now, LC_ALL and LANG serve the different purposes. LC_ALL overrides
any LC_*, and LANG provides the default fallback.
Testcase:
/usr/bin/env LC_ALL=C LC_TIME=de_DE.ISO_8859-1 /bin/date
Should return date in the "C" locale format.
Inspired by: date(1) reference page in the Draft
lock definitions to it. flockfile state is now allocated
along with the rest of FILE. This eliminates the need for a
separate allocation of flockfile state as well as eliminating
the mutex/lock used to serialize its allocation.
Even better formula from random() could not be intetgrated because rand_r()
supposed to store its state in the single variable (but table needed for
random() algorithm integration).
- new EV_SET macro,
- NOTE_LOWAT option for low water marks on read/write filters,
- NOTE_REVOKE for filesystem unmounting (and revoke() calls)
- improved API for EVFILT_AIO
This is about to be replaced anyway by initialization explicitly
instead of lazily, and reducing the complexity of it. As it is
now, this will work fine, however.
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.
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.
Lots of head scratching and ideas and testing by: green, imp
causing some versions of as to dump core. This survived make
buildworld/installworld and the building gettext port afterwards.

We'll fix the "how do we stop encoding sizeof(FILE) in binaries" part

Change __dtoa to not free the string it allocated the previous time it was

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.
Asbestos suit on: check!
Peril sensitive sunglasses on: check!
*gulp!*
try a hopefully more robust stdin/stdout/stderr. This costs an indirect
pointer fetch, but saves us from changes in 'FILE'. 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.

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.
A few K&R -> ANSI conversions along with removal of a few instances
of "register".
$Id$ -> $FreeBSD$ in libc/stdio/rget.c
Not objected to: -arch, a few months ago
it in.
Some review from -hackers (some time ago), and I think the best way to
get this improved (if it needs improving) or updating, is to bring it in.
