2020-03-26Add a module function to open a file descriptor connected to a pipe.Philipp Stephani
A common complaint about the module API is that modules can't communicate asynchronously with Emacs. While it isn't possible to call arbitrary Emacs functions asynchronously, writing to a pipe should always be fine and is a pretty low-hanging fruit. This patch implements a function that adapts an existing pipe process. That way, users can use familiar tools like process filters or 'accept-process-output'. * src/module-env-28.h: Add 'open_channel' module function. * src/emacs-module.c (module_open_channel): Provide definition for 'open_channel'. (initialize_environment): Use it. * src/process.c (open_channel_for_module): New helper function. (syms_of_process): Define necessary symbol. * test/src/emacs-module-tests.el (module/async-pipe): New unit test. * test/data/emacs-module/mod-test.c (signal_system_error): New helper function. (signal_errno): Use it. (write_to_pipe): New function running in the background. (Fmod_test_async_pipe): New test module function. (emacs_module_init): Export it. * doc/lispref/internals.texi (Module Misc): Document new module function. * doc/lispref/processes.texi (Asynchronous Processes): New anchor for pipe processes. * etc/NEWS: Document 'open_channel' function.
2020-03-26Remove COERCE_MARKERPaul Eggert
* src/xdisp.c (COERCE_MARKER): Remove. All uses replaced by Fmarker_position; this is simpler as the macro was invoked only on markers.

* src/editfns.c (Fline_beginning_position, Fline_end_position): Do not restrict integer arguments to fixnums.
2020-03-25Fix integer overflow in internal_self_insertPaul Eggert
* src/cmds.c (internal_self_insert): Avoid undefined behavior on integer overflow by using saturated add.
2020-03-25Fix integer overflow in forward-pointPaul Eggert
* lisp/subr.el (forward-point): Rewrite in Lisp and move here ... * src/cmds.c (Fforward_point): ... from here. This fixes an integer overflow bug with (forward-point most-positive-fixnum).

2020-03-22Don't signal during backtrace unrewind (Bug#40088)Noam Postavsky
backtrace_eval_unrewind is used to temporarily reverse let-bindings (it's called with a positive argument to reverse bindings, and then a negative argument to re-apply them) by backtrace--locals and backtrace-eval. For the SPECPDL_LET_DEFAULT and SPECPDL_LET_LOCAL cases (which occur for let-bindings on buffer-local variables), the code calls Fdefault_value and Fbuffer_local_value on the symbol. For symbols which are unbound at top-level, the first (with positive argument) call to backtrace_eval_unrewind will set the symbol's value to unbound (putting the current value in the specpdl's "old value" slot). On the second (with negative argument) call, backtrace_eval_unrewind attempts to retrieve the symbol's value with Fdefault_value or Fbuffer_local_value, but that raises a void-variable signal. This interrupts the restoration of the let-bindings, so any other variables more recent on the stack will now have the wrong value. * src/data.c (default_value): Make non-static. * src/lisp.h: Declare it. * src/eval.c (backtrace_eval_unrewind): Replace the calls to Fdefault_value and Fbuffer_local_value with default_value and buffer_local_value, respectively. The latter do exactly the same as the former, except if the symbol's value is Qunbound they just return it instead of signaling void-variable.
2020-03-22Avoid extra "changed on disk" prompt in save-buffer (Bug#18336)Noam Postavsky

2020-03-19Fix display of :box face when overlay strings are aroundEli Zaretskii
* src/xdisp.c (reset_box_start_end_flags): New function. (handle_face_prop): Only set the start_of_box_run_p flag, don't reset it. (pop_it): Set the face_box_p flag, if the popped face requires that, when continuing iteration over buffer text. (get_next_display_element, next_element_from_display_vector): Only set the end_of_box_run_p flag, never reset it here. (set_iterator_to_next): Don't reset the start_of_box_run_p and end_of_box_run_p flags here. They are now reset as side effect of PRODUCE_GLYPHS. (append_space_for_newline): Restore the end_of_box_run_p flag after PRODUCE_GLYPHS where we previously didn't reset it. * src/dispextern.h (PRODUCE_GLYPHS): Call reset_box_start_end_flags after producing glyphs. (Bug#40124)
