emacs/src/systhread.h, branch scratch/fontify-open-string

Make error checking for thread functions stricter.

2018-06-09T16:47:10+00:00

* src/systhread.c (sys_thread_create): Change return type to bool.
Check for errors returned by pthread_attr_setstacksize and
pthread_attr_destroy.
(sys_mutex_init): Abort on errors.  Enable mutex checks when checking
is enabled.
(sys_cond_init): Abort on errors.
(sys_mutex_lock, sys_mutex_unlock, sys_cond_wait)
(sys_cond_signal, sys_cond_broadcast, sys_cond_destroy): Check for
errors in debug mode.

Fix module support if threads are disabled (Bug#30106)

2018-01-18T19:14:36+00:00

* src/systhread.c (sys_thread_equal): New function.
* src/thread.c (in_current_thread): Move from emacs-module.c; use
sys_thread_equal.

Prefer HTTPS to FTP and HTTP in documentation

2017-09-13T22:54:37+00:00

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November.  Change these FTP URLs to https://ftp.gnu.org
instead.  Make similar changes for URLs to other organizations moving
away from FTP.  Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

Remove a few unused C functions

2017-02-26T17:58:25+00:00

* src/eval.c (let_shadows_global_binding_p):
* src/print.c (write_string):
* src/systhread.c (sys_mutex_destroy, sys_thread_equal):
Remove.
* src/print.c (write_string): Rename from write_string_1.
All uses changed.

Update copyright year to 2017 in master

2017-01-01T09:48:59+00:00

Run admin/update-copyright in the master branch.  This fixes files
that were not already fixed in the emacs-25 branch before it was
merged here.

Improve MS-Windows implementation of threads.

2013-08-31T11:29:05+00:00

 src/systhread.c (sys_cond_init): Set the 'initialized' member to
 true only if initialization is successful.  Initialize wait_count
 and wait_count_lock.
 (sys_cond_wait, sys_cond_signal, sys_cond_broadcast): If
 'initialized' is false, do nothing.
 (sys_cond_wait): Fix the implementation to avoid the "missed
 wakeup" bug: count the waiting threads, and reset the broadcast
 event once the last thread was released.
 (sys_cond_signal, sys_cond_broadcast): Use SetEvent instead of
 PulseEvent.  Don't signal the event if no threads are waiting.
 (sys_cond_destroy): Only close non-NULL handles.
 (sys_thread_create): Return zero if unsuccessful, 1 if successful.
 src/systhread.h (w32thread_cond_t): New member 'initialized'.
 Rename waiters_count and waiters_count_lock to wait_count and
 wait_count_lock, respectively.

Enable thread support in the MS-Windows build.
