* 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.

* | Fix quitting bug when buffers are frozenPaul Eggert2017-02-011-0/+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.
* | Revamp quitting and fix infloopsPaul Eggert2017-02-011-7/+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.
* | Remove immediate_quit.Paul Eggert2017-02-011-7/+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.
* | Replace QUIT with maybe_quitPaul Eggert2017-01-251-8/+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.

| | | | | | | | | | | | * 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.
* | Change two _Noreturn functions to return voidPaul Eggert2016-12-061-8/+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.
* | Restore file descriptor limit in subprocessesPaul Eggert2016-11-061-0/+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.
* | Limit <config.h>’s includesPaul Eggert2016-09-301-0/+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.

All uses removed. (main): Make sure standard FDs are OK. Prefer symbolic names like EXIT_FAILURE to magic numbers like 1. Use bool for boolean. * src/lisp.h (init_standard_fds): New decl. * src/print.c (WITH_REDIRECT_DEBUGGING_OUTPUT) [GNU_LINUX]: Remove; no longer needed. (Fredirect_debugging_output): Define on all platforms, not just GNU/Linux. Redirect file descriptor, not stream, so that the code works even if stderr is not an lvalue. Report an error if the file arg is neither a string nor nil. (syms_of_print): Always define redirect-debugging-output. * src/sysdep.c (force_open, init_standard_fds): New functions.
* Rework C source files to avoid ^(Paul Eggert2016-03-101-4/+4
| | | | | | | | 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.

* Omit unnecessary \ before paren in C docstringsPaul Eggert2015-09-161-2/+2
| | | | | | | | | Although \( is needed in docstrings in Elisp code, it is not needed in docstrings in C code, since C function definitiions do not start with a parenthesis. The backslashes made the docstrings a bit harder to read and to format in columns. Also, some C docstrings had ( in column 1 and this did not appear to be causing any problems. So, simplify C docstrings by replacing \( with ( and \) with ).
