* 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.

* Rework C source files to avoid ^(Paul Eggert2016-03-101-2/+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.

All instances of '#include <setjmp.h>' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler.

* Simplify redefinition of 'abort' (Bug#12316).Paul Eggert2012-09-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | Do not try to redefine the 'abort' function. Instead, redo the code so that it calls 'emacs_abort' rather than 'abort'. This removes the need for the NO_ABORT configure-time macro and makes it easier to change the abort code to do a backtrace. * configure.ac (NO_ABRT): Remove. * admin/CPP-DEFINES (NO_ABORT): Remove. * nt/inc/ms-w32.h (w32_abort) [HAVE_NTGUI]: Remove. * src/.gdbinit: Just stop at emacs_abort, not at w32_abort or abort. * src/emacs.c (abort) [!DOS_NT && !NO_ABORT]: Remove; sysdep.c's emacs_abort now takes its place. * src/lisp.h (emacs_abort): New decl. All calls from Emacs code to 'abort' changed to use 'emacs_abort'. * src/msdos.c (dos_abort) [defined abort]: Remove; not used. (abort) [!defined abort]: Rename to ... (emacs_abort): ... new name. * src/sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking the place of the old 'abort' in emacs.c. * src/w32.c, src/w32fns.c (abort): Do not #undef. * src/w32.c (emacs_abort): Rename from w32_abort.

* * scroll.c: Integer and memory overflow fixes.Paul Eggert2011-07-281-26/+15
| | | | | (do_line_insertion_deletion_costs): Check for size calculation overflow. Don't bother calling xmalloc when xrealloc will do.
* GLYPH_DEBUG fixesPaul Eggert2011-06-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | The following patches are for when GLYPH_DEBUG && !XASSERT. * dispextern.h (trace_redisplay_p, dump_glyph_string): * dispnew.c (flush_stdout): * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph): Mark as externally visible. * dispnew.c (check_window_matrix_pointers): Now static. * dispnew.c (window_to_frame_vpos): * xfns.c (unwind_create_frame): * xterm.c (x_check_font): Remove unused local. * scroll.c (CHECK_BOUNDS): * xfaces.c (cache_fache): Rename local to avoid shadowing. * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static. * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
