Why did the code previously under !USE_GTK have to be removed? When the !USE_GTK code is used an abort in glib will happen stochastically due to an out-of-sync call to release_select_lock in thread.c. This happens on my system somewhere between approximately 1 in 10 and 1 in 10000 times that the test file is run. As far as I can tell from testing there is no difference in behavior between the USE_GTK and !USE_GTK code. Also, as far as I can tell from reading, the behavior should be almost identical. The only addition is to check for already_has_events before calling thread_select, which may be enough to shift the timing to prevent a race. I have not been able to figure out what the actual underlying cause is (I tried). All I can say for sure is that there is something that calls into g_main_context_release and context->owner_count has a negative overflow to 4294967295. I do not think that it is because something somehow sneaks in between the calls to the atomics in acquire_select_lock and relese_select_lock. If you would like I can send along a couple of patches that include changes I made to try to see what is going on. The real underlying issue would seem to be that there is a missing lock somewhere and that the use of atomics is not sufficient, but I could be wrong about that.

Thanks. The commit message does not really comply with our style, however. The ChangeLog entries should look like this instead: * src/xgselect.c (xg_select): Remove ifdefs that were previously USE_GTK specific to be unconditional. This prevents a race condition caused by a call to release_select_lock from triggering when configuring Emacs with any toolkit other than GTK. (release_select_lock): Add a branch to check whether threads_holding_glib_lock has gone negative, and if so, restore to zero. In the case where there are multiple threads, threads_holding_glib_lock could become and stay negative, prevending g_main_context_release from ever being called, even when it should have been. You can use C-c C-w inside a *vc-log* buffer to generate an appropriately formatted commit message.

There is a race condition in xgselect.c leading to an abort being
raised in glib code. I have attached a patch that fixes the issue.
It took an absurd amount of time to track this down and debug. The
patch and repro file contain more information.
This is not the easiest bug to test for because the race condition is
non-deterministic, I have attached the elisp file that I use to
explore and reproduce the issue.
Ensure that you have glib installed and that you are building --with-x
so that the code in xgselect is enabled. Run configure as ./configure
--with-x-toolkit=lucid (or anything except gtk), and then run make.
Assuming process-thread-bugs.el is in the top level of the emacs repo
define the following function
function loop-abort () { while true; do src/emacs -Q -batch -l \
./process-thread-bugs.el will abort 1 || return $?; done }
You can then run loop-abort; echo $? and when the patch is not applied
Emacs will eventually abort. You can also add a call to fputs in
thread.c at the location of the comment and you will almost
immediately see the abort behavior, even when building with gtk.
