| | | | | | * src/thread.c (Fmake_condition_variable, Fcondition_wait) (Fcondition_notify, Fcondition_mutex, Fcondition_name, Fmake_thread) (Fthread_join, Fall_threads): Doc fixes.
* Fix building with check-lisp-object-typeEli Zaretskii2016-12-101-1/+1
| | | | | | * src/thread.c (mark_one_thread): Use NILP to compare with m_saved_last_thing_searched, which is a Lisp object. Reported by Andreas Politz <politza@hochschule-trier.de>.
* Documentation and commentary improvementsEli Zaretskii2016-12-103-0/+6
| | | | | | | | | | | | * src/lisp.h: * src/regex.c: * src/xgselect.c (xg_select): Improve commentary and formatting. * doc/lispref/objects.texi (Thread Type, Mutex Type) (Condition Variable Type): New subsections. (Type Predicates): Add thread-related predicates. * doc/lispref/objects.texi (Editing Types): * doc/lispref/elisp.texi (Top): Update higher-level menus.

* Fix compilation error on Fedora 24Eli Zaretskii2016-12-091-6/+0
| | | | | * src/sysdep.c [HAVE_H_ERRNO]: Remove declaration of h_errno. Reported by Paul Eggert <eggert@cs.ucla.edu>.
* Fix compilation warnings due to prototype of thread_selectEli Zaretskii2016-12-094-5/+5
| | | | | | | | * src/thread.h <int select_func>: Make the 5th and 6th arguments be 'const'. * src/process.c [WINDOWSNT]: * src/w32proc.c: Make the 5th and 6th argument to sys_select be 'const'.
* Fix compilation on Debian GNU/LinuxEli Zaretskii2016-12-091-0/+1
| | | | | * src/thread.h: Include sys/types.h, for ssize_t that regex.h uses. Reported by Robert Marshall <robert.marshall@codethink.co.uk>.
* Fix subtle errors with let-binding of localized variablesEli Zaretskii2016-12-091-16/+14
| | | | | | | | | | * src/eval.c (do_specbind): Don't require a "symbol" that is actually a cons cell, in order to call set-default, as there are no longer such bindings. This makes do_specbind work like the pre-concurrency implementation in specbind for bindings of forwarded symbols. Use specpdl_kind to access the type of the binding. (specpdl_kind): New function.
* Fix compilation warningsEli Zaretskii2016-12-081-1/+1
| | | | | * src/thread.c (Fmake_thread): Call emacs_abort, to avoid compilation warning.
* Fix network streams.Eli Zaretskii2016-12-073-20/+27
| | | | | The original code messed up flags in fd_callback_data[], and also didn't call add_process_read_fd for process-related file descriptors.

| * | Fix crashes when unbind_for_thread_switch signals an error.Eli Zaretskii2013-09-014-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | src/eval.c (unbind_for_thread_switch): Accept a 'struct thread_state *' argument and use specpdl_ptr and specpdl of that thread. Fixes crashes if find_symbol_value signals an error. src/thread.c (post_acquire_global_lock): Update current_thread before calling unbind_for_thread_switch. Pass the previous thread to unbind_for_thread_switch.
| * | Improve MS-Windows implementation of threads.Eli Zaretskii2013-08-314-14/+98

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functions called via flush_stack_call_func are assumed to return with the global lock held again, and with current_thread reset. this assertion verifies part of this

| * | | | | | | avoid current_thread sometimesTom Tromey2013-07-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this tweaks thread.c to use 'self' instead of current_thread in a couple spots. this is clearer and more robust

| * | | | | | | introduce thread_alive_p macroTom Tromey2013-07-031-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces the thread_alive_p macro and changes thread-alive-p to use it. This is a minor cleanup. It also changes all-threads to ignore dead threads.
| * | | | | | | Don't call unbind_for_thread_switch in run_threadTom Tromey2013-07-031-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the call to unbind_for_thread_switch from run_thread. This isn't necessary because acquire_global_lock does it properly.
