* ; * src/process.c (child_signal_read): Don't report EAGAIN as errorMattias Engdegård2021-01-291-1/+1

* ; * src/process.c (child_signal_read): Remove FIXME comment.Eli Zaretskii2021-01-231-1/+0

* Add a FIXME comment to improve the SIGCHLD race condition handling.Philipp Stephani2021-01-231-0/+5
| | | | | * src/process.c: Add FIXME comment describing how we could avoid the self-pipe on modern Unix-like systems.
* Mark both ends of self-pipe a nonblocking.Philipp Stephani2021-01-231-0/+2
| | | | | | | | | While no deadlocks caused by the blocking write end have been reported yet, marking both ends nonblocking is consistent and also recommended in the GNU/Linux manpage of 'select'. * src/process.c (child_signal_init): Mark write end of self-pipe as nonblocking.
* Clean up the recently added self-pipe mechanism for WINDOWSNTEli Zaretskii2021-01-231-2/+21
| | | | | * src/process.c (child_signal_init, child_signal_read) (child_signal_notify): #ifdef away on WINDOWSNT.
* Make child signal read pipe non-blocking.Philipp Stephani2021-01-191-0/+2
| | | | | | | | | Otherwise Emacs might hang when trying to read the pipe twice in a row. This is consistent with the other file descriptors we pass to 'pselect'. * src/process.c (child_signal_init): Make read end of pipe non-blocking.
* Ensure that sentinels are called during 'accept-process-output'.Philipp Stephani2021-01-171-0/+9
| | | | | | | | | | | | When we're trying to notify a process about a status change, we need to ignore the SIGCHLD pipe temporarily, otherwise the code would likely not run into the timeout case that's necessary for a status change to happen. * src/process.c (wait_reading_process_output): Ignore the SIGCHLD pipe when notifying a process about a status change. * test/src/process-tests.el (process-tests/sentinel-called) (process-tests/sentinel-with-multiple-processes): New unit tests.
* Don't crash if no asynchronous process has been created yet.scratch/sigchld-fdPhilipp Stephani2021-01-161-2/+2
| | | | | * src/process.c (wait_reading_process_output): Allow child_signal_read_fd < 0.
* Fix deadlock when receiving SIGCHLD during 'pselect'.Philipp Stephani2021-01-161-1/+93
| | | | | | | | | | | | | | | | | | | | | | If we receive and handle a SIGCHLD signal for a process while waiting for that process, 'pselect' might never return. Instead, we have to explicitly 'pselect' that the process status has changed. We do this by writing to a pipe in the SIGCHLD handler and having 'wait_reading_process_output' select on it. * src/process.c (child_signal_init): New helper function to create a pipe for SIGCHLD notifications. (child_signal_read, child_signal_notify): New helper functions to read from/write to the child signal pipe. (create_process): Initialize the child signal pipe on first use. (handle_child_signal): Notify waiters that a process status has changed. (wait_reading_process_output): Make sure that we also catch SIGCHLD/process status changes. * test/src/process-tests.el (process-tests/fd-setsize-no-crash/make-process): Remove workaround, which is no longer needed.
* Remove a pointless check for WCOREDUMPED.Philipp Stephani2021-01-101-2/+1
| | | | | | | WCOREDUMPED can only be used if the process was killed. * src/process.c (status_convert): Don't check WCOREDUMPED if WIFEXITED.
* Don't unblock SIGCHLD too early.Philipp Stephani2021-01-091-1/+9
| | | | | | | | | | | | We first need to register the received process ID so that 'handle_child_signal' checks it. Otherwise we might never call 'waitpid' for these processes, risking deadlock. * src/callproc.c (call_process): * src/process.c (create_process): Don't unblock SIGCHLD before registering the process ID to wait for. * src/callproc.c (emacs_spawn): Accept a signal set from the caller.
* Port to Solaris 10Paul Eggert2021-01-011-9/+0
| | | | | | | | | | | | | | | | | | | | | | * configure.ac: Instead of AC_CHECK_HEADER, use AC_COMPILE_IFELSE with X11/Intrinsic.h when checking for X11/extensions/Xrender.h. This suppresses a bogus "report a bug to bug-gnu-emacs" diagnostic from 'configure' in Solaris 10. (SETUP_SLAVE_PTY): Adjust to recent renaming of forkin to std_in in callproc.c. Needed on Solaris and Unixware. * lib-src/Makefile.in (LIB_GETRANDOM, LIBS_ETAGS): New vars, needed because on Solaris 10 the Gnulib tempname module now needs the -lrt library for clock_gettime. Throw in the LIB_GETRANDOM stuff too while we’re at it; from getrandom.m4 it seems to be needed for MingW. (LIBS_MOVE, etags_libs): Use them. * src/callproc.c [SETUP_SLAVE_PTY]: Include sys/stream.h and sys/stropts.h, for SETUP_SLAVE_PTY’s definiens. * src/process.c [NEED_BSDTTY]: Don’t include bsdtty.h; hasn’t been needed in years. [USG5_4]: Don’t include sys/stream.h or sys/stropts.h; these directives havbe been moved to callproc.c because the only use of SETUP_SLAVE_PTY is there now.

| | | | | | | | | | * src/process.c (Fmake_serial_process): Add port to error data. (connect_network_socket): Add an explanatory comment.
* | Manually limit file descriptors that we select on to FD_SETSIZE.Philipp Stephani2020-12-311-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This works even if another thread or process resets the resource limit for open file descriptors, e.g., using 'prlimit' on GNU/Linux. * src/process.c (create_process, create_pty, Fmake_pipe_process) (Fmake_serial_process, connect_network_socket) (server_accept_connection): Limit file descriptors to FD_SETSIZE. * test/src/process-tests.el (process-tests--with-raised-rlimit): New helper macro. (process-tests--fd-setsize-test): Rename from 'process-tests--with-many-pipes'. Increase resource limit during test if possible. (process-tests/fd-setsize-no-crash/make-process) (process-tests/fd-setsize-no-crash/make-pipe-process) (process-tests/fd-setsize-no-crash/make-network-process) (process-tests--new-pty): Rename callers.

* | Fix test/src/process-tests on MS-WindowsEli Zaretskii2020-12-261-0/+6
| | | | | | | | | | * src/process.c (network_lookup_address_info_1) [WINDOWSNT]: Initialize winsock.
* | Unbreak the MinGW build broken by recent changes in callproc.cEli Zaretskii2020-12-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/w32.h (set_process_dir): * src/w32proc.c (set_process_dir): Change the argument to 'const char *'. * src/lisp.h (make_environment_block): * src/callproc.c (make_environment_block): Now returns 'char **'. (exec_failed) [DOS_NT]: Remove unused function. * src/callproc.c (child_setup): NEW_ARGV and ENV are now 'char **'. Making them 'const' breaks the MinGW build and is not needed for other platforms. * src/callproc.c (emacs_spawn): ARGV and ENVP arguments are now 'char *', for the same reason. * src/process.c (create_process): Adapt to above changes.
* | Centralize subprocess creation in a single function.Philipp Stephani2020-12-241-142/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Getting the vfork + execve combination right isn't easy, and the code was partially duplicated between callproc.c and process.c. Centralize the spawn operation in a single function that deals with the nasty details. Going forward, we should be able to use posix_spawn from either libc or Gnulib (or CreateProcessW on Windows) in the non-pty case. * src/callproc.c (emacs_spawn): New function to start an asynchronous subprocess. Merge code from 'call_process' and 'create_process' into this function. (call_process): Use new 'emacs_spawn' function. (child_setup): Make static, since there are no users outside this compilation unit left. (CHILD_SETUP_TYPE): Move from header file, since there are no users outside this compilation unit left. * src/process.c (create_process): Use new 'emacs_spawn' function.
* | Pass C string pointer to current directory to 'child_setup'.Philipp Stephani2020-12-231-2/+4
| | | | | | | | | | | | | | | | | | | | | | This avoids the impression that 'child_setup' could do anything Lisp-related. * src/callproc.c (child_setup): Pass C pointer to current directory name. (call_process): Adapt callers. * src/process.c (create_process): Adapt callers.
* | Allocate environment block before forking.Philipp Stephani2020-12-231-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While 'child_setup' carefully avoids calls to async-signal-unsafe functions like 'malloc', it seems simpler and less brittle to use normal allocation outside the critical section between 'fork' and 'exec'. * src/callproc.c (make_environment_block): New function to create the environment block for subprocesses. Code largely extracted from 'child_setup' and adapted to use 'xmalloc' instead of 'alloca'. (child_setup): Remove environment block allocation in favor of passing the environment block as command-line argument. (call_process): Adapt to new calling convention. * src/process.c (create_process): Adapt to new calling convention.
* | Remove an unused parameter from 'child_setup' function.Philipp Stephani2020-12-231-2/+2
| | | | | | | | | | | | | | * src/callproc.c (child_setup): Remove unused SET_PGRP parameter. * src/callproc.c (call_process): * src/process.c (create_process): Fix all callers.

(Fget_buffer_create): Use it. Add optional argument to set inhibit_buffer_hooks flag instead of comparing the buffer name to Vcode_conversion_workbuf_name. All callers changed. (Fmake_indirect_buffer, Frename_buffer, Fbury_buffer_internal) (record_buffer): Use run_buffer_list_update_hook. (Fkill_buffer): Document when buffer hooks are inhibited. Use run_buffer_list_update_hook. (init_buffer_once): Inhibit buffer hooks in Vprin1_to_string_buffer.

* | Remove some unused process.c variablesLars Ingebrigtsen2020-12-121-5/+0

* | * src/keyboard.c: Fix bug#5803.Stefan Monnier2020-12-121-38/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A long time ago, `read_key_sequence` used to read the keymaps at the start, so if something happened between this start and the moment the user actually hits a key, `read_key_sequence` could end up using the wrong keymaps. To work around this problem, the code used `record_asynch_buffer_change` to try and trigger `read_key_sequence` to re-read the keymaps in some known cases. Several years ago, `read_key_sequence` was changed so as to read the keymaps only once the user hits a key, making this machinery now redundant (and also harmful apparently in bug#5803 because it introduces "spurious" events). So we here remove `record_asynch_buffer_change` and the `BUFFER_SWITCH_EVENT` and `Qbuffer_switch` pseudo-events it generated. * src/termhooks.h (enum event_kind): Delete `BUFFER_SWITCH_EVENT`. * src/keyboard.c: (record_asynch_buffer_change): Delete function. (syms_of_keyboard): Delete `Qbuffer_switch`. (force_auto_save_soon, readable_events) (kbd_buffer_store_buffered_event, kbd_buffer_get_event) (make_lispy_event): * src/xterm.c (handle_one_xevent): * src/w32term.c (w32_read_socket): * src/process.c (wait_reading_process_output) (read_and_dispose_of_process_output, exec_sentinel): Simplify accordingly.
* | Work around glib messing with signal handlers more than it shouldAkira Kyle2020-11-141-5/+21

* | Tweak updating the process mark in set-process-bufferLars Ingebrigtsen2020-09-251-2/+5
| | | | | | | | | | * src/process.c (Fset_process_buffer): Only update the process mark if we actually change the buffer.

| | | | | | | | | | | | | | * src/callproc.c (Fcall_process_region): (Fcall_process): * src/process.c (Fmake_process): Mention `exec-path' in the doc strings (bug#42704).
* | Fix problem where TLS connections would sometimes hangDerek Zhou2020-08-031-51/+46
| | | | | | | | | | | | | | | | | | | | * src/process.c (wait_reading_process_output): Before the select, check every interesting gnutls stream for available data in the buffer. If some of them hit, and either there is no wait_proc or the wait_proc is one of the gnutls streams with new data, set the select timeout to 0 after the select, and merge the gnutls buffer status into the select returns (bug#40665). This fixes a problem where TLS connections would sometimes hang.
* | Improve integer range checkingPaul Eggert2020-04-051-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/bignum.c (check_integer_range, check_uinteger_max) (check_int_nonnegative): New functions. * src/frame.c (check_frame_pixels): New function. (Fset_frame_height, Fset_frame_width, Fset_frame_size): Use it. * src/lisp.h (CHECK_RANGED_INTEGER, CHECK_TYPE_RANGED_INTEGER): Remove these macros. Unless otherwise specified, all callers replaced by calls to check_integer_range, check_uinteger_range, check_int_nonnegative. * src/frame.c (gui_set_right_divider_width) (gui_set_bottom_divider_width): * src/nsfns.m (ns_set_internal_border_width): * src/xfns.c (x_set_internal_border_width): Using check_int_nonnegative means these functions no longer incorrectly reject negative bignums; they treat them as 0, just like negative fixnums.
* | Make make-{network,serial}-process handle :coding nil consistentlyRobert Pluim2020-04-031-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of :coding nil was different between make-{network,serial}-process and make-{pipe}process. Now they all handle :coding nil as if :coding had not been specified. * process.c (Fmake_serial_process) (set_network_socket_coding_system): Use plist-get to check if :coding has been specified instead of plist-member, to ensure that ":coding nil" does not override coding-system-for-{read,write}. * network-stream-tests.el (check-network-process-coding-system-bind) (check-network-process-coding-system-no-override) (check-network-process-coding-system-override): New tests. * etc/NEWS: Describe change in make-network-process and make-serial-process :coding behavior.
* | Add a module function to open a file descriptor connected to a pipe.Philipp Stephani2020-03-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'.
