2020-04-12Fix error in 'call-process-region' when START is nil (Bug#40576)Philipp Stephani1-1/+11
* src/callproc.c (Fcall_process_region): Fix behavior when START is nil and DELETE is non-nil. * test/src/callproc-tests.el (call-process-region-entire-buffer-with-delete): New unit test.
2020-02-13Make after-change-functions called from call-process get the correct BEGAlan Mackenzie1-2/+3
This fixes bug #39585. * src/callproc.c (call_process): Supply the correct CHARPOS to signal_after_change (twice).
2020-01-27; Spelling and URL fixesPaul Eggert1-1/+1
2020-01-22Make call_process call signal_after_change. This fixes bug #38691.Alan Mackenzie1-3/+34
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.

2019-11-02Fix data-directory when executing from an out-of-source buildÓscar Fuentes1-1/+1
Fixes #36828. * src/callproc.c (init_callproc): detect out-of-source build.
2019-09-21Revert too-picky file-access testsPaul Eggert1-2/+2
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.
2019-09-18Fix permission-denied issue in MS-Windows startupPaul Eggert1-5/+4
* src/callproc.c (init_callproc): Use file_access_p rather than Ffile_exists_p during startup (Bug#37445).
2019-09-16Fix initialization of shared-game-score-directory on MS-WindowsEli Zaretskii1-2/+13
* src/callproc.c (init_callproc) [WINDOWSNT]: Run PATH_GAME through w32_relocate, to expand %emacs_dir%. [DOS_NT]: Accept EACCES as not "unusual" errno value. Reported by Richard Copley <rcopley@gmail.com>.
2019-09-15Improve directory-access diagnosticsPaul Eggert1-0/+2

2019-04-14Let debugger handle process spawn errors on w32 (Bug#33016)Noam Postavsky1-5/+2
Since child_setup() is called between block_input()...unblock_input(), when an error is signaled the Lisp debugger is prevented from starting. Therefore, let the callers signal the error instead (which they already do for non-w32 platforms, just the error message needs an update). * src/callproc.c (child_setup) [WINDOWSNT]: Don't call report_file_error here. (call_process) [WINDOWNT]: * src/process.c (create_process) [WINDOWSNT]: Call report_file_errno here instead, after the unblock_input() call, same as for !WINDOWSNT. * src/lisp.h (CHILD_SETUP_ERROR_DESC): New preprocessor define. Flip the containing ifndef DOS_NT branches so that it's ifdef DOS_NT. * src/eval.c (when_entered_debugger): Remove. (syms_of_eval) <internal-when-entered-debugger>: Define it as a Lisp integer variable instead. (maybe_call_debugger): Update comment. * test/src/process-tests.el (make-process-w32-debug-spawn-error): * test/src/callproc-tests.el (call-process-w32-debug-spawn-error): New tests.

This fixes some URLs I omitted from my previous pass, notably those in lists.gnu.org. Although lists.gnu.org does not yet support TLS 1.1, TLS 1.0 is better than nothing. * lisp/erc/erc.el (erc-official-location): * lisp/mail/emacsbug.el (report-emacs-bug): Use https:, not http:.
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.
2017-08-25Simplify expand_and_dir_to_filePaul Eggert1-1/+1
* src/fileio.c (expand_and_dir_to_file): Simplify by omitting 2nd argument, since in practice it always has the default value. All callers changed. Prefer C99 style decls in nearby code.
2017-05-21Work around macOS bug with vforked childPaul Eggert1-0/+8
* src/callproc.c (call_process) [DARWIN_OS]: Include workaround for apparent macOS bug.
2017-05-19Attempt to work around macOS vfork bugPaul Eggert1-4/+9
Problem reported by YAMAMOTO Mitsuharu in: http://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00342.html This is related to the fix for Bug#26397. * src/callproc.c (call_process_cleanup, call_process) [!MSDOS]: Report internal error if wait_for_termination fails. * src/sysdep.c (get_child_status): Return -1 if waitpid is buggy, instead of aborting. (wait_for_termination): Return bool success value. All callers changed.
2017-04-18Use vfork if possible on Darwin (bug#26397)Alan Third1-0/+13
Co-authored-by: YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp> * src/conf_post.h (HAVE_WORKING_VFORK): Don't undef. (vfork): Don't define. * src/process.c (create_process) [DARWIN_OS]: Use fork if pty_flag is set, otherwise vfork. * src/callproc.c (call_process) [DARWIN_OS]: Use TIOCNOTTY to detach the controlling terminal instead of setsid.
2017-04-06Mention that processes start in default-directory (Bug#18515)Noam Postavsky1-0/+4
* doc/lispref/processes.texi (Synchronous Processes): (Asynchronous Processes): * lisp/subr.el (start-process): * src/callproc.c (call-process): Mention that the subprocess starts in `default-directory' when local, suggest `start-file-process' and `process-file' otherwise.
2017-03-12Install update-game-score only on requestPaul Eggert1-12/+8
Most distributions do not install update-game-score properly due to setuid/setgid complications, so install it only when the installer specifies a user or group (Bug#25895). * .gitattributes: Remove lib-src/update-game-score.exe.manifest. * Makefile.in (gameuser, gamegroup, use_gamedir, PATH_GAME): New vars. (epaths-force): Use PATH_GAME. (uninstall): Remove snake-scores and tetris-scores only if shared. * configure.ac: Default --with-gameuser to 'no'. (UPDATE_MANIFEST): Remove. * etc/NEWS: Mention this. * lib-src/Makefile.in (UPDATE_MANIFEST): Remove. (use_gamedir): New macro. (UTILITIES): Remove update-game-score unless use_gamedir. (SCRIPTS): Remove $(UPDATE_MANIFEST). ($(DESTDIR)${archlibdir}): Install game directory program and data only if use_gamedir. * lib-src/update-game-score.exe.manifest: Remove, as update-game-score is no longer installed on MS-Windows. * lisp/play/gamegrid.el (gamegrid-add-score-with-update-game-score): Use auxiliary program only if setuid or setgid. * make-dist: Do not distribute update-game-score.exe.manifest. * src/callproc.c (init_callproc): Set Vshared_game_score_directory based on PATH_GAME, not DOS_NT. (syms_of_callproc): Remove unnecessary initialization of Vshared_game_score_directory.
2017-02-18Use 'char *FOO' instead of 'char* FOO'Paul Eggert1-1/+1
2017-02-01Fix quitting bug when buffers are frozenPaul Eggert1-0/+3
Problem noted by Eli Zaretskii in: http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00721.html This patch also fixes some other issues in that report. * src/lisp.h (incr_rarely_quit): Remove. All callers changed to use rarely_quit directly. * src/search.c (freeze_buffer_relocation) (thaw_buffer_relocation): New functions. (looking_at_1, fast_looking_at, search_buffer): Use them to fix bug when quitting when buffers are frozen. * src/sysdep.c (emacs_intr_read): Rename from emacs_nointr_read. All uses changed.
2017-02-01Revamp quitting and fix infloopsPaul Eggert1-7/+2
This fixes some infinite loops that cannot be quitted out of, e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#))) when byte-compiled and when run under X. See: http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00577.html This also attempts to keep the performance improvements I recently added, as much as possible under the constraint that the infloops must be caught. In some cases this fixes infloop bugs recently introduced when I removed immediate_quit. * src/alloc.c (Fmake_list): Use rarely_quit, not maybe_quit, for speed in the usual case. * src/bytecode.c (exec_byte_code): * src/editfns.c (Fcompare_buffer_substrings): * src/fns.c (Fnthcdr): * src/syntax.c (scan_words, skip_chars, skip_syntaxes) (Fbackward_prefix_chars): Use rarely_quit so that users can C-g out of long loops. * src/callproc.c (call_process_cleanup, call_process): * src/fileio.c (read_non_regular, Finsert_file_contents): * src/indent.c (compute_motion): * src/syntax.c (scan_words, Fforward_comment): Remove now-unnecessary maybe_quit calls. * src/callproc.c (call_process): * src/doc.c (get_doc_string, Fsnarf_documentation): * src/fileio.c (Fcopy_file, read_non_regular, Finsert_file_contents): * src/lread.c (safe_to_load_version): * src/sysdep.c (system_process_attributes) [GNU_LINUX]: Use emacs_read_quit instead of emacs_read in places where C-g handling is safe. * src/eval.c (maybe_quit): Move comment here from lisp.h. * src/fileio.c (Fcopy_file, e_write): Use emacs_write_quit instead of emacs_write_sig in places where C-g handling is safe. * src/filelock.c (create_lock_file): Use emacs_write, not plain write, as emacs_write no longer has a problem. (read_lock_data): Use emacs_read, not read, as emacs_read no longer has a problem. * src/fns.c (rarely_quit): Move to lisp.h and rename to incr_rarely_quit. All uses changed.. * src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member): * src/indent.c (compute_motion): * src/syntax.c (find_defun_start, back_comment, forw_comment) (Fforward_comment, scan_lists, scan_sexps_forward): Use incr_rarely_quit so that users can C-g out of long loops. * src/fns.c (Fnconc): Move incr_rarely_quit call to within inner loop, so that it catches C-g there too. * src/keyboard.c (tty_read_avail_input): Remove commented-out and now-obsolete code dealing with interrupts. * src/lisp.h (rarely_quit, incr_rarely_quit): New functions, the latter moved here from fns.c and renamed from rarely_quit. (emacs_read_quit, emacs_write_quit): New decls. * src/search.c (find_newline, search_buffer, find_newline1): Add maybe_quit to catch C-g. * src/sysdep.c (get_child_status): Always invoke maybe_quit if interruptible, so that the caller need not bother. (emacs_nointr_read, emacs_read_quit, emacs_write_quit): New functions. (emacs_read): Rewrite in terms of emacs_nointr_read. Do not handle C-g or signals; that is now for emacs_read_quit. (emacs_full_write): Replace PROCESS_SIGNALS two-way arg with INTERRUPTIBLE three-way arg. All uses changed.
2017-02-01Remove immediate_quit.Paul Eggert1-7/+1
The old code that sets and clears immediate_quit was ineffective except when Emacs is running in terminal mode, and has problematic race conditions anyway, so remove it. This will introduce some hangs when Emacs runs in terminal mode, and these hangs should be fixed in followup patches. * src/keyboard.c (immediate_quit): Remove. All uses removed.
2017-01-25Replace QUIT with maybe_quitPaul Eggert1-8/+8
There’s no longer need to have QUIT stand for a slug of C statements. Use the more-obvious function-call syntax instead. Also, use true and false when setting immediate_quit. These changes should not affect the generated machine code. * src/lisp.h (QUIT): Remove. All uses replaced by maybe_quit.
2016-12-31Update copyright year to 2017Paul Eggert1-1/+1
Run admin/update-copyright.
2016-12-31Don't define NOMINMAX on MS-WindowsEli Zaretskii1-1/+0
* src/callproc.c (NOMINMAX) [WINDOWSNT]: Don't define. This is no longer needed with the current sources and MinGW headers, while defining NOMINMAX causes an annoying compiler warning.
2016-12-06Change two _Noreturn functions to return voidPaul Eggert1-8/+8
This is a bit clearer than _Noreturn functions that (do not) return a non-void type. * src/callproc.c (call_process) [MSDOS]: Use 'status' local to record status. (child_setup): Return CHILD_SETUP_TYPE. * src/data.c, src/lisp.h (wrong_type_argument): Return void. All callers changed. * src/lisp.h (CHILD_SETUP_TYPE): New macro.
2016-11-06Restore file descriptor limit in subprocessesPaul Eggert1-0/+3
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.
2016-09-30Limit <config.h>’s includesPaul Eggert1-0/+1
This follows up on recent problems with the fact that config.h includes stdlib.h etc.; some files need to include stdlib.h later. config.h generally should limit itself to includes that are universally safe; outside of MS-Windows, only stdbool.h makes the cut among the files currently included. So, move the other includes to just the files that need them (Bug#24506). * configure.ac (config_opsysfile): Remove, as this generic hook is no longer needed. * lib-src/etags.c, src/unexmacosx.c, src/w32.c, src/w32notify.c: * src/w32proc.c (_GNU_SOURCE): Remove, as it’s OK for config.h to do this now. * src/conf_post.h: Include <ms-w32.h>, instead of the generic config_opsysfile, for simplicity as this old way of configuring is now done only for the MS-Windows port. Do not include <ms-w32.h> if DEFER_MS_W32_H, for the benefit of the few files that want its effects later. Do not include <alloca.h>, <string.h>, or <stdlib.h>. Other files modified to include these headers as needed, or to not include headers that are no longer needed. * src/lisp.h: Include <alloca.h> and <string.h> here, since some of the inline functions need them. * src/regex.c: Include <alloca.h> if not emacs. (If emacs, we can rely on SAFE_ALLOCA.) There is no longer any need to worry about HAVE_ALLOCA_H. * src/unexmacosx.c: Rely on config.h not including stdlib.h. * src/w32.c, src/w32notify.c, src/w32proc.c (DEFER_MS_W32_H): Define before including <config.h> first, and include <ms-w32.h> after the troublesome headers.
2016-08-20Some assorted documentation clarificationsPhilipp Stephani1-0/+7
* src/fileio.c (Fwrite_region): Clarify that END is ignored if START is nil. * src/editfns.c (Fbuffer_size): Add short discussion about narrowing. * src/callproc.c (Fcall_process_region): Discuss behavior when START and END are not buffer positions.
2016-07-20Fix port to glibc 2.24 (pre-release) + ppc64Paul Eggert1-2/+2
* src/callproc.c (child_setup): Use emacs_exec_file so that ASLR is enabled in the child process. * src/emacs.c: Move some personality details into sys/sysdep.c. Do not include <sys/personality.h>. (main): Disable ASLR earlier, so that we don’t chdir twice. * src/lisp.h (disable_address_randomization): New decl. * src/sysdep.c (disable_address_randomization) [HAVE_PERSONALITY_ADDR_NO_RANDOMIZE]: Move personality details here from emacs.c. (emacs_exec_file): New function.
2016-07-19; Spelling fixPaul Eggert1-1/+1
2016-07-18Keep w32 environment settings internal onlyNoam Postavsky1-0/+14
* src/emacs.c (main) [WINDOWSNT]: Move init_environment calls after the set_initial_environment call. This prevents Emacs' modifications to the environment from contaminating Vprocess_environment and Vinitial_environment (Bug #10980). * src/callproc.c (getenv_internal) [WINDOWSNT]: Consult Emacs' internal environment in as a fallback to Vprocess_environment. * test/src/callproc-tests.el (initial-environment-preserved): New Test.
2016-06-20Fix removal of variables from process-environmentEli Zaretskii1-1/+1
* src/callproc.c (add_env): Fix comparison of a variable with a value against the same variable without a value. (Bug#23779)
2016-05-21Fix compiler warnings in the MinGW buildEli Zaretskii1-2/+2
* configure.ac [mingw32]: Don't add -Wpointer-sign, and add -Wno-pointer-sign, to keep the noise level down. * nt/mingw-cfg.site (gl_cv_warn_c__Wredundant_decls): Disable -Wredundant-decls, as that produces a lot of noise due to redeclaration of time-related functions by gnulib. * nt/runemacs.c (set_user_model_id): Fix argument type of 'SetCurrentProcessExplicitAppUserModelID'. * src/image.c (x_create_bitmap_from_file) [HAVE_NTGUI]: Don't declare 'dpyinfo', as it is unused.

(sys_rename_replace): Use %d to avoid compiler warnings. (_wsa_errlist): Make the message text 'const char *', to avoid compilation warnings. (dynlib_reset_last_error): Move prototype to file scope. (w32_get_resource): First argument is now 'const char *'. * src/w32uniscribe.c (syms_of_w32uniscribe): Provide prototype.

(current_popup_menu): Remove redundant declaration. (colormap_t): Member 'name' is now 'const char *'. (add_system_logical_colors_to_map): Fix signed/unsigned warnings. (x_decode_color, x_set_border_pixel) (x_clear_under_internal_border, x_set_name, hook_w32_key) (reset_w32_kbdhook_state, deliver_wm_chars, w32_backtrace): Now static.
