* Add a module function to open a file descriptor connected to a pipe.Philipp Stephani2020-03-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/process.c (read_process_output): Track bytes read from a process. (wait_reading_process_output): If called recursively through timers and/or process filters via accept-process-output, it is possible that the output of wait_proc has already been read by one of those recursive calls, leaving the original call hanging forever if no further output arrives through that fd and no timeout has been set. Fix that by using the process read accounting to keep track of how many bytes have been read and use that as a condition to break out of the infinite loop and return to the caller as well as to calculate the proper return value (if a wait_proc is given that is). * src/process.h (struct Lisp_Process): Add nbytes_read to track bytes read from a process. (cherry picked from commit 4ba32858d61eee16f17b51aca01c15211a0912f8)
* | Dissociate controlling tty better on DarwinPaul Eggert2018-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | * src/process.c (dissociate_controlling_tty): New function. (create_process): Use it to dissociate controlling tty if setsid fails, which happens on Darwin after a vfork (Bug#33154). Do this on all platforms, not just on Darwin, as a similar problem is plausible elsewhere. * src/callproc.c (call_process): Use the new function here, too, for consistency and to avoid duplicate code.

* | Use native alignment to access Lisp object dataPaul Eggert2018-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to tell GCC that P has alignment 8, use (T *) P where T is the type of the pointed-to object, to tell GCC that P has native alignment. This is simpler, matches the intent better, and should help simplify future improvements. Some of these changes are to pacify gcc -Wnull-dereference, since GCC is smarter about pointers now that Emacs no longer uses __builtin_assume_aligned; these minor changes should improve code efficiency slightly. On Fedora 28 x86-64 with default optimization this patch shrinks the size of the Emacs text segment by 0.36%. * src/conf_post.h (__has_builtin, __builtin_assume_aligned): Remove; no longer used. * src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE): Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE and XCDR instead of CDR_SAFE when this is safe. * src/fileio.c (Fexpand_file_name): * src/font.c (clear_font_cache): Pacify -Wnull-dereference by removing unnecessary NILP test. * src/keyboard.c (xevent_start): New function. (read_char, read_key_sequence): Pacify -Wnull-dereference by using xevent_start instead of EVENT_START. * src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro now, since it can no longer be implemented as a function. (XUNTAG): New third argument CTYPE. All uses changed. Cast result to CTYPE * instead of using __builtin_assume_aligned. Simplify by using LISP_WORD_TAG. (LISP_WORD_TAG): New macro. (TAG_PTR): Use it. * src/menu.c (x_popup_menu_1): Pacify -Wnull-dereference by using XCAR instead of Fcar and XCDR instead of Fcdr where this is safe.

| | | | | | | * src/lisp.h (vectorlike_headed): Change from struct to union. All uses changed. Since it has only one member, this does not change semantics. This is designed to simplify future changes needed to fix bugs like Bug#29040. All uses changed.
* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | 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.

* | Reorder lisp.h to declare types before using themPaul Eggert2016-12-251-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This puts basic functions for types to be after the corresponding type definitions. This is a more-common programming style in C, and will make it easier to port Emacs to gcc -fcheck-pointer-bounds, since the functions now have access to the corresponding types' sizes. This patch does not change the code; it just moves declarations and definitions and removes no-longer-needed forward declarations (Bug#25128). * src/buffer.c, src/data.c, src/image.c: Include process.h, for PROCESSP. * src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER): * src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS): * src/termhooks.h (TERMINALP, XTERMINAL): * src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW): * src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX) (XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR): Move here from lisp.h. * src/intervals.h: Include buffer.h, for BUFFERP. Include lisp.h, for Lisp_Object. * src/lisp.h: Reorder declarations and definitions as described above. Move thread includes to be later, so that they can use the reordered definitions. Move some symbols to other headers (noted elsewhere). Remove forward decls that are no longer needed. * src/thread.h: Include systhread.h here, not in lisp.h, since lisp.h itself does not need systhread.h.

It introduces a wrapper for select that releases the global lock, and it ensures that only a single thread can select a given file descriptor at a time. This also adds the thread-locking feature to processes. By default a process can only have its output accepted by the thread that created it. This can be changed using set-process-thread. (If the thread exits, the process is again available for waiting by any thread.) Note that thread-signal will not currently interrupt a thread blocked on select. I'll fix this later.

Set pid to -1 while the process is being created. (start_process_unwind): Omit unnecessary emacs_abort test. (connect_network_socket): Simplify use of counts.

This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.
* | | | | | | | | | | | | | | Allow making TLS negotiation blockingLars Magne Ingebrigtsen2016-03-051-0/+1

(gnutls_try_handshake): Complete negotiation if given that keyword. * src/process.h (L): Added gnutls_complete_negotiation_p.
* | | | | | | | | | | | | | | Integer overflow cleanups for ports and socklenPaul Eggert2016-02-251-1/+1

This addresses only a theoretical problem, as in practice these object sizes are less than 2**31, but we might as well use the same style here as elsewhere in Emacs. (string_integer_p): Remove; all uses removed. (Fmake_network_process): Check that port number is in range. When converting an integer-string service, rely on strtol rather than rechecking the string by hand. * src/process.h, src/w32.c (conv_sockaddr_to_lisp): Adjust prototypes to match.

(Fmake_network_process): Use list1 for brevity. (wait_for_socket_fds): 2nd arg is now const ptr. * src/process.h (struct Lisp_Process.dns_request): Now struct gaicb *, not struct gaicb **, since there was always exactly one. All uses changed. * src/window.c, src/window.h (run_window_configuration_change_hook): Now static.
