The GNU/kFreeBSD (and BSDs in general) have a different
layout of struct sockaddr, sockaddr_in, sockaddr_un ...
The first member do not have to be "sa_family",
they also have "sa_len" field.

As you know there are some nasty libs / apps doing locking
incorrectly. In order to improve the information given to the user
when he encounters such a situation (people don't run apps in gdb
normally) I created the patch attached.
It's very non-intrusive (and affects only xlib/xcb, Josh told me on
irc that it could be useful for other areas too, personally I don't
think that it's really needed at other places ...).
Some same outputs and the discussion of them:
lxuser@pdln:/tmp$ ./main
Got a backtrace:
#0 /tmp/usr/lib/libxcb-xlib.so.0 [0xb7f9d728]
#1 /tmp/usr/lib/libxcb-xlib.so.0(xcb_xlib_unlock+0x31) [0xb7f9d861]
#2 ./test.so(function_a+0x11) [0xb7f9f3fd]
#3 ./test.so(function_b+0x11) [0xb7f9f410]
#4 ./main [0x80484a7]

#6 ./main [0x80483f1]
main: xcb_xlib.c:82: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
Aborted
That's kinda the normal situation.

There are two possible reasons that the name doesn't appear in #2:
a) a hidden symbol or a symbol with statical linkage in a library
b) a symbol in an app not compiled with -rdynamic.
But in both cases you still know _where_ the caller is.
Note that in this example test.so was compiled with
-fomit-frame-pointer; this isn't an issue as _one_ (= the caller)
stack trace is still valid (as long as you don't have the insane idea
to compile xcb with -fo-f-p).
Another issue that may appear is "tail call elimination" (some entries
are mysteriously missing; this is quite ugly, but you still get enough
information so that you can do something useful with the issue e.g. by
disassembling the relevant parts with gdb).

The documentation generation with doxygen now works when built out of tree,
with srcdir != builddir. xcb.doxygen now gets generated from xcb.doxygen.in,
so that it can use top_builddir and top_srcdir to find source and to output
documentation. Also fill in PROJECT_NUMBER from @VERSION@, now that we have
it readily available via autoconf.

configure supports using custom CFLAGS, so remove the --with-opt and
--with-debug options from configure.ac, and the corresponding usage of
COPTFLAGS and CDEBUGFLAGS in src/Makefile.am.

Since the addition of IPv6 support, we now use getaddrinfo rather than
gethostbyname; update configure.ac accordingly.

versions.
|
|
check 0.9.4 is now required to build XCB's unit tests.
The version that we were requiring was not actually new enough to let
our unit tests compile, and the AM_PATH_CHECK macro is now considered
deprecated. We know that versions of check using pkg-config are new
enough to work, and the check dependency was optional anyway, so we've
dropped support for older versions.

We don't want to have to change the libxcb soname if we later manage to remove
the Xlib compatibility functions, and nothing except Xlib should ever use
them, so split them into a separate library.

from the new .pc.in files in configure.ac. Install the new .pc files in Makefile.am, and add the new .pc.in files to EXTRA_DIST.
Based on a patch by Vincent Torri. Changes from that patch: add Requires to the .pc.in files based on the <import>s in the extensions, add a .pc.in file for libXCBxtest, change Name and Description fields to match extension names.

XCBSendRequest and write_setup.
This requires dynamically allocating memory in XCBSendRequest, but this
malloc/free pair turns out to cause a 30% speed hit for the 'x11perf -noop'
test -- so for the moment I use alloca where available and fall back to malloc
on other platforms. Later I think I'll change the contract of XCBSendRequest
so the caller is responsible for memory allocation, because the caller ought
to always be able to stack-allocate here.
