2022-03-16Improve error message for 'not running' processesRobert Pluim
The current error message is simply 'not running', but 'status_message' can give information about why the process is in that state, such as network errors, so return that as well. (Bug#53762) * src/process.c (send_process, Fprocess_send_eof): Add the output of 'status_message' to the error string.
2022-02-12Replace ptrdiff_t with new specpdl_ref type for specpdl referencesMattias Engdegård
The specpdl_ref type is just an alias for ptrdiff_t; the compiled code remains the same. All operations on specpdl_ref (arithmetic, comparison etc) now go through inline functions. The bulk of the change is almost completely mechanical. It is done to prepare for a type-safe representation and subsequent performance improvement. * src/lisp.h (specpdl_ref, specpdl_count_to_ref, specpdl_ref_to_count) (specpdl_ref_eq, specpdl_ref_lt, specpdl_ref_valid_p) (make_invalid_specpdl_ref, specpdl_ref_add, specpdl_ref_to_ptr): New.

2021-07-13Block TLS handshake until TCP connection establishedMattias Engdegård
If a TLS handshake is attempted before the completion of an asynchronous TCP connection has been ascertained, our local state will not be set up correctly for further progress and the sentinel "open" event will never be sent. This can occur if sufficient time passes after the initiation of an async TCP connection so that by the time `wait_reading_process_output` is called, the connection has already been established on the TCP level. This somewhat timing-sensitive bug has plagued HTTPS connections on some platforms, notably macOS, for a long time (bug#49449). * src/process.c (wait_reading_process_output): Gate the TLS handshake by the NON_BLOCKING_CONNECT_FD flag. The flag will be cleared as soon as the TCP socket is found to be writable. * test/src/process-tests.el (process-async-https-with-delay): New test.
2021-07-04Ensure 'call-process' interprets INFILE as a local pathJim Porter

2021-01-29; * src/process.c (child_signal_read): Don't report EAGAIN as errorMattias Engdegård
2021-01-23; * src/process.c (child_signal_read): Remove FIXME comment.Eli Zaretskii
2021-01-23Add a FIXME comment to improve the SIGCHLD race condition handling.Philipp Stephani
* src/process.c: Add FIXME comment describing how we could avoid the self-pipe on modern Unix-like systems.
2021-01-23Mark both ends of self-pipe a nonblocking.Philipp Stephani
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.
2021-01-23Clean up the recently added self-pipe mechanism for WINDOWSNTEli Zaretskii
* src/process.c (child_signal_init, child_signal_read) (child_signal_notify): #ifdef away on WINDOWSNT.
2021-01-19Make child signal read pipe non-blocking.Philipp Stephani
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.
2021-01-17Ensure that sentinels are called during 'accept-process-output'.Philipp Stephani
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.
2021-01-16Don't crash if no asynchronous process has been created yet.Philipp Stephani
* src/process.c (wait_reading_process_output): Allow child_signal_read_fd < 0.
2021-01-16Fix deadlock when receiving SIGCHLD during 'pselect'.Philipp Stephani
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.
2021-01-10Remove a pointless check for WCOREDUMPED.Philipp Stephani
WCOREDUMPED can only be used if the process was killed. * src/process.c (status_convert): Don't check WCOREDUMPED if WIFEXITED.
2021-01-09Don't unblock SIGCHLD too early.Philipp Stephani
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.
2021-01-01Port to Solaris 10Paul Eggert
* 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.
