2022-02-12Rewrite thread context switch code (bug#48990)Stefan Monnier
Make the context switch code handle buffer-local variables more correctly by reusing the code originally written for `backtrace-eval`. This has the side benefit of making the `saved_value` field unused. * src/lisp.h (enum specbind_tag): Remove `saved_value` field. (rebind_for_thread_switch, unbind_for_thread_switch): Delete decls. (specpdl_unrewind): Declare function. * src/eval.c (specpdl_saved_value): Delete function. (specbind): Delete the code related to `saved_value`, and consolidate common code between the different branches. (rebind_for_thread_switch, -unbind_for_thread_switch): Move to `thread.c`. (specpdl_unrewind): New function, extracted from `backtrace_eval_unrewind`. Use `SET_INTERNAL_THREAD_SWITCH`. Skip the buffer & excursion unwinds depending on new arg `vars_only`. (backtrace_eval_unrewind): Use it. (mark_specpdl): Don't mark `saved_value`. * src/thread.c (rebind_for_thread_switch, unbind_for_thread_switch): Move from `eval.c` and rewrite using `specpdl_unrewind`. * test/src/thread-tests.el (threads-test-bug48990): New test. * test/Makefile.in (test_template): Add a + as suggested by make: "warning: jobserver unavailable: using -j1. Add '+' to parent make rule".

2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert
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.
2017-01-18Rudimentary error handling for non-main threadsEli Zaretskii

2017-01-13Fix last changeEli Zaretskii
* test/src/thread-tests.el (threads-condvar-wait): Revert previous change. Make sure no other threads from previous tests are running, to avoid interfering with our thread counts.
2017-01-13Fix the new condvar testEli Zaretskii
* test/src/thread-tests.el (threads-condvar-wait): Enlarge the time we sleep in the main thread to let the other thread process notifications.
2017-01-13Minor improvements in the new condvar testEli Zaretskii
* test/src/thread-tests.el (threads-test-condvar-wait): Use with-mutex instead of emulating it inline. (threads-condvar-wait): Improve comments. Check that the new thread is alive before waiting for it to become blocked on the conditional variable.

2016-12-22; Spelling fixesPaul Eggert
2016-12-12Avoid crashing if a new thread is signaled right awayEli Zaretskii
* src/thread.c (post_acquire_global_lock): Don't raise the pending signal if the thread's handlers were not yet set up, as that will cause Emacs to exit with a fatal error. This can happen if a thread is signaled as soon as make-thread returns, before the new thread had an opportunity to acquire the global lock, set up the handlers, and call the thread function. * test/src/thread-tests.el (thread-signal-early): New test.
2016-12-12Fix point motion in cloned buffersEli Zaretskii
* src/thread.c (post_acquire_global_lock): Call set_buffer_internal_2 instead of tricking set_buffer_internal_1 into resetting the current buffer even if it didn't change. This avoids bug#25165, caused by failing to record the modified values of point and mark, because current_buffer was set to NULL. Also, don't bother re-setting the buffer if there was no thread switch, as that just wastes cycles. * src/buffer.c (set_buffer_internal_2): New function, with most of the body of set_buffer_internal_1, but without the test for B being identical to the current buffer. (set_buffer_internal_1): Call set_buffer_internal_2 if B is not identical to the current buffer. * src/buffer.h (set_buffer_internal_2): Add prototype. * test/src/thread-tests.el (thread-sticky-point): New test.
2016-12-11Avoid aborts when a thread signals an errorEli Zaretskii
* src/thread.h (struct thread_state): Add members m_waiting_for_input and m_input_available_clear_time. (waiting_for_input, input_available_clear_time): New macros. * src/keyboard.c (waiting_for_input, input_available_clear_time): Remove; they are now macros that reference the current thread. (Bug#25171) * src/w32select.c: Don't include keyboard.h. * test/src/thread-tests.el (thread-errors): New test.
