2020-03-26Add a module function to open a file descriptor connected to a pipe.Philipp Stephani1-0/+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.

2019-04-08Allow gap before first non-Lisp pseudovec memberPaul Eggert1-3/+1
Problem reported by Keith David Bershatsky in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00259.html Solution suggested by Stefan Monnier in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html * src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE. (BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE. * src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field, not the first non-Lisp field. All callers changed. Callers without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR. (ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.

2018-11-10Dissociate controlling tty better on DarwinPaul Eggert1-0/+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.
2018-09-06Shrink pseudovectors a bitPaul Eggert1-1/+1

Problem noted by Stefan Monnier in: https://lists.gnu.org/r/emacs-devel/2018-09/msg00165.html * src/bignum.h (struct Lisp_Bignum): * src/frame.h (struct frame): * src/lisp.h (struct Lisp_Vector, struct Lisp_Bool_Vector) (struct Lisp_Char_Table, struct Lisp_Hash_Table) (struct Lisp_Marker, struct Lisp_Overlay) (struct Lisp_Misc_Ptr, struct Lisp_User_Ptr) (struct Lisp_Finalizer, struct Lisp_Float) (struct Lisp_Module_Function): * src/process.h (struct Lisp_Process): * src/termhooks.h (struct terminal): * src/thread.h (struct thread_state, struct Lisp_Mutex) (struct Lisp_CondVar): * src/window.c (struct save_window_data): * src/window.h (struct window): * src/xterm.h (struct scroll_bar): * src/xwidget.h (struct xwidget, struct xwidget_view): Add GCALIGNED_STRUCT attribute. * src/lisp.h (GCALIGNED_UNION_MEMBER): Renamed from GCALIGNED_UNION. All uses changed. (GCALIGNED_STRUCT_MEMBER, GCALIGNED_STRUCT, GCALIGNED): New macros. All uses of open-coded GCALIGNED changed to use GCALIGNED. (union vectorlike_header): No longer GC-aligned. (PSEUDOVECSIZE): Yield 0 for pseudovectors without Lisp objects that place a member before where the first Lisp object member would be.

2018-06-24Return the entire TLS certificate chain back to the callerLars Ingebrigtsen1-1/+2
* src/gnutls.c (gnutls_deinit_certificates): New function. (Fgnutls_peer_status): Return all certificates in the chain back to Lisp land. (gnutls_verify_boot): Compute all the x509 certificates in the chain. * src/process.h (struct Lisp_Process): Adjust gnutls fields so that we can keep tracks of all certificates in the chain instead of just the host certificate.
2018-06-10Use native alignment to access Lisp object dataPaul Eggert1-1/+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.
2018-06-02Fix wait_reading_process_output wait_proc hangMatthias Dahl1-0/+2
* 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)

* 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.
2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert1-1/+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.

2016-12-25Reorder lisp.h to declare types before using themPaul Eggert1-0/+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.
2016-11-06Restore file descriptor limit in subprocessesPaul Eggert1-0/+1
Problem reported by Philipp Stephani (Bug#24869). * src/callproc.c (child_setup) [!DOS_NT]: Call restore_nofile_limit in the child. * src/process.c (nofile_limit) [HAVE_SETRLIMIT]: New static var. (restore_nofile_limit): New function. (init_process_emacs) [HAVE_SETRLIMIT]: Set the new var.
2016-08-11Fix process leak with make-network-processPaul Eggert1-4/+5
This problem was introduced by the recent async changes (Bug#23808). * src/process.c (Fmake_process): Move USE_SAFE_ALLOCA later, so that it follows the start_process_unwind unwind-protect. 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. Unwind bind_polling_period a bit earlier, so that a remove_process unwind-protect can be added when needed; this is the heart of the fix. Undo the unwind-protect just before returning.
2016-06-26Try other addresses when connecting to multihomedPaul Eggert1-1/+3
Problem reported by Juliusz Chroboczek (Bug#17976) and by Artur Malabarba (Bug#23620). Patch from a suggestion by Andreas Schwab in: http://bugs.gnu.org/17976#39 This patch is for non-MS-Windows platforms. I don't know the situation on MS-Windows. * src/process.c (connecting_status): New function, for (connect . ADDRINFOS). (connect_network_socket, check_for_dns, wait_for_socket_fds) (wait_while_connecting, wait_reading_process_output, status_notify): Use it. (decode_status, Fmake_network_process): Support (connect . ADDRINFOS) status. (connect_network_socket) [!WINDOWSNT]: If the connection failed and there are other addresses to try, do not signal an error; instead, loop around to try the next address. (wait_reading_process_output): Advance to the next address if there are multiple addresses and the first remaining address failed. * src/process.h (struct Lisp_Process.status): Adjust comment to describe (connect . ADDRINFOS).
2016-06-09Fix XFASTINT of non-fixnum in process statusPaul Eggert1-1/+2
* src/process.c (decode_status): 3rd arg is now Lisp_Object *, not int *, and is not decoded. All uses changed. (status_message): Do not assume ‘failed’ code is an integer. * src/process.h: Document codes better.
2016-05-23Don’t use only last protocol from getaddrinfoPaul Eggert1-2/+0
Problem reported by Ken Brown in: http://lists.gnu.org/archive/html/emacs-devel/2016-05/msg00483.html * src/process.c (conv_addrinfo_to_lisp): New function. (connect_network_socket): Arg is now a list of addrinfos, not merely IP addresses. All uses changed. Use protocol from each addrinfo. (Fmake_network_process): Accumulate protocols into addrinfos rather than just using the last one found. (check_for_dns): Accumulate protocols here, too. * src/process.h (struct Lisp_Process): Remove ai_protocol; no longer needed.
2016-03-10Rework C source files to avoid ^(Paul Eggert1-2/+2
Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. 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.
2016-03-05Allow making TLS negotiation blockingLars Magne Ingebrigtsen1-0/+1
* lisp/net/gnutls.el (gnutls-negotiate): Make negotiation blocking. * src/gnutls.c (Fgnutls_boot): Provide a new keyword, :complete-negotiation, to specify that we want complete negotiation even if the socket is non-blocking. (gnutls_try_handshake): Complete negotiation if given that keyword. * src/process.h (L): Added gnutls_complete_negotiation_p.
2016-02-25Integer overflow cleanups for ports and socklenPaul Eggert1-1/+1
* src/process.c (struct sockaddr_and_len, conv_sockaddr_to_lisp) (get_lisp_to_sockaddr_size, Fset_process_datagram_address) (connect_network_socket): Use ptrdiff_t, not int, for signed object sizes. 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.
2016-02-23Minor cleanups for async DNS etc.Paul Eggert1-1/+1
* src/frame.h (FRAME_WINDOW_CONFIGURATION_CHANGED): Omit unnecessary parens. * src/gnutls.c (gnutls_try_handshake, emacs_gnutls_deinit) (gnutls_verify_boot): Use bool for boolean. (ATTRIBUTE_FORMAT_PRINTF): Add printf attribute. * src/process.c (free_dns_request, Fmake_network_process): Allocate and free async request control block all in one go. (set_network_socket_coding_system, finish_after_tls_connection) (connect_network_socket): Now static. (conv_numerical_to_lisp): 2nd arg is now int, not unsigned. (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.

2016-02-01Further TLS async workLars Ingebrigtsen1-0/+6
* gnutls.c (boot_error): New function to either signal an error or return an error code. (Fgnutls_boot): Don't signal errors when running asynchronously. * process.h (pset_status): Move here from process.c to be able to use from gnutls.c. * process.c (connect_network_socket): Do the TLS boot here when running asynchronously. (wait_reading_process_output): Rework the dns_processes handling for more safety.
2016-01-31Rework the mechanisms for async GnuTLS connectionsLars Ingebrigtsen1-1/+1
* lisp/net/gnutls.el (open-gnutls-stream): Compute the gnutls-boot parameters and pass them to the process object. (gnutls-negotiate): New parameter :return-keywords that won't connect to anything, just compute the keywords. * lisp/url/url-http.el (url-http): Revert async TLS sentinel hack, which is no longer necessary. * src/gnutls.c (Fgnutls_asynchronous_parameters): Rename from gnutls-mark-process. * src/process.c (connect_network_socket): If we're connecting to an asynchronous TLS socket, complete the GnuTLS boot sequence here. * src/process.h: New parameter gnutls_async_parameters.
2016-01-31Implement asynchronous GnuTLS connectionsLars Ingebrigtsen1-0/+1
* doc/misc/emacs-gnutls.texi (Help For Developers): Mention the nowait parameter. * lisp/net/gnutls.el (open-gnutls-stream): Allow asynchronous connections with the new nowait parameter. * lisp/net/network-stream.el (network-stream-open-tls): Pass on :nowait to open-gnutls-stream. * lisp/url/url-http.el (url-http): Don't overwrite the sentinel created by open-gnutls-stream. * src/gnutls.c (Fgnutls_mark_process): New function. * src/process.c (send_process): Don't write to GnuTLS sockets that haven't been initialised yed. * src/process.h: New slot gnutls_wait_p.
2016-01-30Avoid memory leaks in async DNSLars Ingebrigtsen1-1/+1
* process.c (check_for_dns): Free async DNS resources after they've been used.
2016-01-30Implement asynchronous name resolutionLars Ingebrigtsen1-0/+12
* process.c (Fmake_network_process): Do asynchronous DNS lookups if we have getaddrinfo_a and the user requests :nowait. (check_for_dns): New function. (wait_reading_process_output): Check for pending name resolution in the idle loop. * process.h: Add structure for async DNS.
2016-01-28Refactor make_network_processLars Ingebrigtsen1-0/+6
* src/process.c (set_network_socket_coding_system) (connect_network_socket): Refactor out of make_network_process to allow calling connect_network_socket asynchronously.

(CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro. (mark_object): Use it. (sweep_symbols): Sweep lispsym symbols. (symbol_uses_obj): New function. (which_symbols): Use it. Work for lispsym symbols, too. (init_alloc_once): Initialize Vpurify_flag here; no need to wait, since Qt's address is already known now. (syms_of_alloc): Add lispsym count to symbols_consed. * buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0), when testing whether storage is all bits zero. * dispextern (struct image_type): * font.c (font_property_table): * frame.c (struct frame_parm_table, frame_parms): * keyboard.c (scroll_bar_parts, struct event_head): * xdisp.c (struct props): Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and Lisp_Object *, since Qfoo is no longer an object whose address can be taken. All uses changed. * eval.c (run_hook): New function. Most uses of Frun_hooks changed to use it, so that they no longer need to take the address of a Lisp sym. (syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable. * frame.c (syms_of_frame): Add defsyms for the frame_parms table. * keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here. DEFSYM Qdeactivate_mark before the corresponding var. * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line instead of interning their symbols; this avoids duplicates. (LISP_INITIALLY, TAG_PTR) (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT): New macros. (LISP_INITIALLY_ZERO): Use it. (enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol) (EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*): Move decls up, to avoid forward uses. Include globals.h earlier, too. (make_lisp_symbol): New function. (XSETSYMBOL): Use it. (DEFSYM): Now just a placeholder for make-docfile. * lread.c (DEFINE_SYMBOLS): Define, for globals.h. (intern_sym): New function, with body taken from old intern_driver. (intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t. All uses changed. (define_symbol): New function. (init_obarray): Define the C symbols taken from lispsym. Use plain DEFSYM for Qt and Qnil. * syntax.c (init_syntax_once): No need to worry about Qchar_table_extra_slots.

2014-06-01Port signal-handling to DragonFly BSD.Paul Eggert1-2/+0
* callproc.c, sysdep.c (block_child_signal, unblock_child_signal): Move implementations from callproc.c to sysdep.c. * process.h, syssignal.h (block_child_signal, unblock_child_signal): Move declaratations from process.h to syssignal.h. Fixes: debbugs:17646
2014-03-25Handle sigmask better with nested signal handlers.Paul Eggert1-2/+2
* atimer.c (sigmask_atimers): Remove. Remaining use rewritten to use body of this function. * atimer.c (block_atimers, unblock_atimers): * callproc.c (block_child_signal, unblock_child_signal): * sysdep.c (block_tty_out_signal, unblock_tty_out_signal): New arg OLDSET. All callers changed. * atimer.c (block_atimers, unblock_atimers): * callproc.c (block_child_signal, unblock_child_signal): * keyboard.c (handle_interrupt): * sound.c (vox_configure, vox_close): Restore the old signal mask rather than unilaterally clearing bits from the mask, in case a handler is running within another handler. All callers changed. * lisp.h, process.c, process.h, term.c: Adjust decls and callers to match new API. * sysdep.c (emacs_sigaction_init): Don't worry about masking SIGFPE; signal handlers aren't supposed to use floating point anyway. (handle_arith_signal): Unblock just SIGFPE rather than clearing mask. Fixes: debbugs:15561
