Filter them out when installing headers.
Tested by building up bfin-*linux toolchains and building our copy of
uClinux-dist.

UCLIBC_HAS_GETPT unconditionally for __libc_ptyname{1,2}[] and related bloat.
|
|
since posix_openpt lives in getpt.c it has to stay there unconditionally.
|
|
Fixes compilation error for defined UCLIBC_HAS_PTY && !defined UNIX98PTY_ONLY
which need both __libc_ptyname1 and __libc_ptyname2 for ptsname_r().
|
|
- ptsname_r depends on UCLIBC_HAS_PTY just like ptsname()

definition. I seems to produce spurious warning:
libc/inet/resolv.c:1549: warning: 'visibility' attribute ignored on non-class types
(seems like gcc bug)
and it is not really needed - attribute_hidden was already
specified in function _declaration_ so it is not necessary here.
No code changes (verified with objdump).

SIGPIPE handler was attempting to re-acquire an already taken lock.
While at it, stop checking for sigaction failure which is not possible here.

we were closing a FILE, but did not record that fact by setting
a variable to NULL, and then we used it for reading!
While at it, small reduction in bss.

previously selected impl lying around on a distclean. Make sure that this

obfuscated, sorry.

- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few
This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.

were still defining signal to sysv_signal.

The obsolete functions bcopy, index, etc. are not supposed to be used within
uClibc itself. Hence, there is no libc_hidden_def for them, but the previous
patch did not just move libc_hidden_protos, it also added new ones for the
legacy functions. As a result, programs which use these functions can no
longer link with uClibc.
This fixes it by removing the unnecessary libc_hidden_protos. I've also
removed all inclusions of <strings.h> from uClibc source files: since we
define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not
need to duplicate the libc_hidden_proto block in <strings.h>.

1. names with two consecutive dots are not valid
2. if name ends with a dot, dont try appending search domain(s)
alos a few small optimisations are here.

It breaks on arches that don't define proper/complete/nice syscall facilities.
|
|
Fixes superfluous rebuild of pthread_atfork.oS.

The bug: this blocks in syslogd is stopped:
#include <syslog.h>
int main() {
int i;
for (i = 0; i < 10000; i++)
syslog(LOG_INFO, "Testing, disregard....................");
return 0;
}
Fix: set O_NONBLOCK on fd to "/dev/log".
Other fixes: do not try to write to fd -1, do not spin forever or EAGAIN,
use constant sockaddr instead of recreating identical one each time,
eliminate one intermediate function (SUGPIPE sig handler),
use smallints where appropriate, add a few comments.

Fixes build-failures in ldso when switching thread-impl because of missing
rule to make e.g. pthreadtypes.h
Thanks to Peter Kjellerstedt for the reminder.

- adds #warning about incorrect posix_fadvise{,64}()

of formerly 130k.

IPv6 DNS resolv. rfc4159 mandated this 3 years ago. Closes bug 1020.
Also cleans up some stype inconsistensied and saves 2 bytes of rw data.
