* Add functions to open a file without quitting.Philipp Stephani2021-01-10
| | | | | | | | | | | | | | | In some situations, e.g. when the Lisp machinery isn't available, we can't quit. Don't check the quit flags in such situations, in case they contain garbage. * src/sysdep.c (emacs_open_noquit, emacs_openat_noquit): New variants of 'emacs_open' and 'emacs_openat' that don't check the quit flags. * src/emacs.c (main, Fdaemon_initialized): * src/pdumper.c (pdumper_load): * src/w32term.c (w32_initialize): * src/buffer.c (mmap_init): * src/callproc.c (emacs_spawn): Use them where we can't quit.
* Don't unblock SIGCHLD too early.Philipp Stephani2021-01-09
| | | | | | | | | | | | 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 Eggert2021-01-01
| | | | | | | | | | | | | | | | | | | | | | * 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.

* Revert "Use posix_spawn if possible."Eli Zaretskii2020-12-25
| | | | | | This reverts commit 2c79a8f9210db01c86b0e5f236adeb0509519d30. It breaks the MinGW build in too many ways, and should be first tested on a branch.
* Use posix_spawn if possible.Philipp Stephani2020-12-25
| | | | | | | | | | | | posix_spawn is less error-prone than vfork + execve, and can make better use of system-specific enhancements like 'clone' on Linux. Use it if we don't need to configure a pseudoterminal. * src/Makefile.in (LIB_POSIX_SPAWN): New variable. (LIBES): Use it. * src/callproc.c (emacs_spawn): Use posix_spawn on Unix-like system if we don't need to set up a pseudoterminal.

* Unbreak the MinGW build broken by recent changes in callproc.cEli Zaretskii2020-12-24
| | | | | | | | | | | | | | | * 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 Stephani2020-12-24
| | | | | | | | | | | | | | | | | | | | 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.
* Declare argument vector as char *const *.Philipp Stephani2020-12-23
| | | | | | This matches the signature of execve. * src/callproc.c (child_setup): Declare NEW_ARGV as char *const *.
* Pass C string pointer to current directory to 'child_setup'.Philipp Stephani2020-12-23
| | | | | | | | | | | 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 Stephani2020-12-23
| | | | | | | | | | | | | | | | 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 Stephani2020-12-23
| | | | | | | * src/callproc.c (child_setup): Remove unused SET_PGRP parameter. * src/callproc.c (call_process): * src/process.c (create_process): Fix all callers.
* Inhibit buffer hooks in temporary buffersBasil L. Contovounesios2020-12-20

(Creating Buffers): Document new parameter of get-buffer-create and generate-new-buffer. (Buffer List, Killing Buffers): Document when buffer hooks are inhibited. (Current Buffer): * doc/lispref/files.texi (Writing to Files): Document that with-temp-buffer and with-temp-file inhibit buffer hooks. * doc/lispref/internals.texi (Buffer Internals): Document inhibit_buffer_hooks flag. Remove stale comment. * doc/misc/gnus-faq.texi (FAQ 5-8): * lisp/simple.el (shell-command-on-region): Fix indentation. * lisp/files.el (kill-buffer-hook): Document when hook is inhibited.

(with-temp-file, with-temp-buffer, with-output-to-string): * lisp/json.el (json-encode-string): Inhibit buffer hooks in buffer used. * src/buffer.c (run_buffer_list_update_hook): New helper function. (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. (Vkill_buffer_query_functions, Vbuffer_list_update_hook): Document when hooks are inhibited. * src/buffer.h (struct buffer): Update inhibit_buffer_hooks commentary. * src/coding.h (Vcode_conversion_workbuf_name): * src/coding.c (Vcode_conversion_workbuf_name): Make static again since it is no longer needed in src/buffer.c. (code_conversion_restore, code_conversion_save, syms_of_coding): Prefer boolean over integer constants. * src/fileio.c (Finsert_file_contents): Inhibit buffer hooks in " *code-converting-work*" buffer. * src/window.c (Fselect_window): Fix grammar. Mention window-selection-change-functions alongside buffer-list-update-hook. * test/src/buffer-tests.el: Fix requires. (buffer-tests-inhibit-buffer-hooks): New test.

* Make after-change-functions called from call-process get the correct BEGAlan Mackenzie2020-02-13
| | | | | | | This fixes bug #39585. * src/callproc.c (call_process): Supply the correct CHARPOS to signal_after_change (twice).
* ; Spelling and URL fixesPaul Eggert2020-01-27

* Make call_process call signal_after_change. This fixes bug #38691.Alan Mackenzie2020-01-22
| | | | | | | | | | | Now, functions such as call-proess-region invoke after-change-functions correctly. * src/callproc.c (call_process): Call prepare_to_modify_buffer in a single place, no longer delegating the task to insert_1_both, etc. Call signal_after_change in each of two code branches, such that before-change-functions and after-change-functions are always called in balanced pairs.

* Revert too-picky file-access testsPaul Eggert2019-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | Problem reported by Andreas Schwab (Bug#37475). * doc/lispref/files.texi (Writing to Files) (Testing Accessibility, Kinds of Files): Document that accessibility and file-type predicates return nil if there is trouble determining accessibility or type. * etc/NEWS: Adjust, and list the affected primitives. * src/callproc.c (init_callproc): Go back to Ffile_exists_p. * src/fileio.c (PICKY_EACCES, file_test_errno): Remove. All uses removed. (Ffile_name_case_insensitive_p, Ffile_exists_p, Ffile_symlink_p) (Ffile_directory_p, Ffile_regular_p): Document that these functions return nil if there is trouble. (Ffile_name_case_insensitive_p, check_file_access) (Ffile_writable_p, Ffile_symlink_p, Ffile_directory_p) (Ffile_accessible_directory_p, Ffile_regular_p) * src/lread.c (Fload): Go back to treating trouble in determining the answer as if the file were missing. * src/fileio.c (Ffile_newer_than_file_p): Use file_attribute_errno not file_test_errno, since returning nil is not appropriate when there are two files to test; e.g., in the rare cases where both file timestamps have overflowed then neither t nor nil is correct.
* Fix permission-denied issue in MS-Windows startupPaul Eggert2019-09-18
| | | | | * src/callproc.c (init_callproc): Use file_access_p rather than Ffile_exists_p during startup (Bug#37445).

* Omit duplicate test of current directoryPaul Eggert2019-09-11
| | | | | | * src/callproc.c (encode_current_directory): Remove redundant call to Ffile_accessible_directory_p. The code checks the encoded name with file_accessible_directory_p anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since child_setup() is called between block_input()...unblock_input(), when an error is signaled the Lisp debugger is prevented from starting.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-13
| | | | | | | | | | | | | 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.
