* 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.
* | Include <malloc.h> when advisablePaul Eggert2016-01-301-22/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should help insulate us better from future glibc changes. It is good hygiene to include .h files for APIs that Emacs uses. Fix type clashes between Emacs and GNU <malloc.h> (Bug#22086). * configure.ac: Check for malloc.h. * src/alloc.c: Include <malloc.h> depending on HAVE_MALLOC_H, not on DOUG_LEA_MALLOC. * src/emacs.c, src/gmalloc.c (malloc_enable_thread): Remove decl (now in lisp.h). * src/gmalloc.c: Include stddef.h earlier, for ptrdiff_t. [emacs]: Include lisp.h. [HAVE_MALLOC_H]: Include <malloc.h>. (__MALLOC_HOOK_VOLATILE): New macro, if not already defined. (__after_morecore_hook, __malloc_initialize_hook, __morecore) (__default_morecore): [!HAVE_MALLOC_H]: New decls near non-inclusion of <malloc.h>. (calloc): Make it clear that the macro should not be used. Remove unused decl. (malloc_info): New macro, to avoid clash with glibc <malloc.h>. (__morecore, __default_morecore, __after_morecore_hook) (__malloc_extra_blocks, __malloc_initialize_hook, __free_hook) (__malloc_hook, __realloc_hook, __memalign_hook, memory_warnings): Remove later decls. (gmalloc_hook, gfree_hook, grealloc_hook): Rename from __malloc_hook, __free_hook, __realloc_hook to avoid type collision with glibc <malloc.h>. All uses changed. (gmalloc_hook): (__malloc_extra_blocks) [DOUG_LEA_MALLOC||HYBRID_MALLOC||SYSTEM_MALLOC]: Now static. (gmalloc_hook, __malloc_extra_blocks): Define even if [!HYBRID_MALLOC]. (__malloc_initialize_hook, __after_morecore_hook): Declare with types compatible with glibc. (__memalign_hook, hybrid_calloc) [HYBRID_MALLOC]: Remove. All uses removed. * src/lisp.h (__malloc_extra_blocks, malloc_enable_thread): New decls. * src/ralloc.c, src/vm-limit.c: Simplify includes and include <malloc.h> if available.

Don't initialize malloc. * src/lisp.h (NONPOINTER_BITS) [CYGWIN]: Define (because GNU_MALLOC is no longer defined on Cygwin). (refill_memory_reserve) [HYBRID_MALLOC]: Don't declare. * src/sheap.c (bss_sbrk_buffer_end): New variable. * src/unexcw.c (__malloc_initialized): Remove variable. * src/ralloc.c: Throughout, treat HYBRID_MALLOC the same as SYSTEM_MALLOC. * src/xdisp.c (decode_mode_spec) [HYBRID_MALLOC]: Don't check Vmemory_full.

(interrupt_input_pending): Remove. All uses removed. pending_signals now counts both atimers and ordinary interrupts. This is less racy than having three separate pending-signal flags. (block_input, unblock_input, totally_unblock_input, unblock_input_to) (input_blocked_p): Rename from their upper-case counterparts BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO, INPUT_BLOCKED_P, and turn into functions. All uses changed. This makes it easier to access volatile variables more accurately. (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input (). (input_blocked_p): Prefer this to 'interrupt_input_blocked', as that's more reliable if the code is buggy and sets interrupt_input_blocked to a negative value. All uses changed. * src/atimer.c (deliver_alarm_signal): Remove. No need to deliver this to the parent; any thread can handle this signal now. All uses replaced by underlying handler. * src/atimer.c (turn_on_atimers): * src/dispnew.c (handle_window_change_signal): * src/emacs.c (handle_danger_signal): * src/keyboard.c (kbd_buffer_get_event): Don't reestablish signal handler; not needed with sigaction. * src/blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT) (UNBLOCK_INPUT_TO): Rework to avoid unnecessary accesses to volatile variables. (UNBLOCK_INPUT_TO): Now a function. (totally_unblock_input, unblock_input): New decls. * src/data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c (init_data): Remove. Necessary stuff now done in init_signal. * src/emacs.c, src/xdisp.c: Include "atimer.h", since we invoke atimer functions. * src/emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c. (fatal_error_code): Remove; no longer needed. (terminate_due_to_signal): Rename from fatal_error_backtrace, since it doesn't always backtrace. All uses changed. No need to reset signal to default, since sigaction and/or die does that for us now. Use emacs_raise (FOO), not kill (getpid (), FOO). (main): Check more-accurately whether we're dumping. Move fatal-error setup to sysdep.c * src/floatfns.c: Do not include "syssignal.h"; no longer needed. * src/gtkutil.c (xg_get_file_name, xg_get_font): Remove no-longer-needed signal-mask manipulation. * src/keyboard.c, src/process.c (POLL_FOR_INPUT): Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined. * src/keyboard.c (read_avail_input): Remove. All uses replaced by gobble_input. (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code. (kbd_buffer_store_event_hold, gobble_input): (record_asynch_buffer_change) [USABLE_SIGIO]: (store_user_signal_events): No need to mess with signal mask. (gobble_input): If blocking input and there are terminals, simply set pending_signals to 1 and return. All hooks changed to not worry about whether input is blocked. (process_pending_signals): Clear pending_signals before processing them, in case a signal comes in while we're processing. By convention callers now test pending_signals before calling us. (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input): New functions, to support changes to blockinput.h. (handle_input_available_signal): Now extern. (reinvoke_input_signal): Remove. All uses replaced by handle_async_input. (quit_count): Now volatile, since a signal handler uses it. (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All callers changed. Block SIGINT only if not already blocked. Clear sigmask reliably, even if Fsignal returns, which it can. Omit unnecessary accesses to volatile var. (quit_throw_to_read_char): No need to restore sigmask. * src/keyboard.c (gobble_input, handle_user_signal): * src/process.c (wait_reading_process_output): Call signal-handling code rather than killing ourselves. * src/lisp.h: Include <float.h>, for... (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication. (pending_signals): Now volatile. (syms_of_data): Now const if IEEE floating point. (handle_input_available_signal) [USABLE_SIGIO]: (terminate_due_to_signal, record_child_status_change): New decls. * src/process.c (create_process): Avoid disaster if memory is exhausted while we're processing a vfork, by tightening the critical section around the vfork. (send_process_frame, process_sent_to, handle_pipe_signal) (deliver_pipe_signal): Remove. No longer needed, as Emacs now ignores SIGPIPE. (send_process): No need for setjmp/longjmp any more, since the SIGPIPE stuff is now gone. Instead, report an error if errno is EPIPE. (record_child_status_change): Now extern. PID and W are now args. Return void, not bool. All callers changed. * src/sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]: Remove. All uses removed. This bug should be fixed now in a different way. (wait_for_termination_1): Use waitpid rather than sigsuspend, and record the child status change directly. This avoids the need to futz with the signal mask. (process_fatal_action): Move here from emacs.c. (emacs_sigaction_flags): New function, containing much of what used to be in emacs_sigaction_init. (emacs_sigaction_init): Use it. Block nonfatal system signals that are caught by emacs, to make races less likely. (deliver_process_signal): Rename from handle_on_main_thread. All uses changed. (BACKTRACE_LIMIT_MAX): Now at top level. (thread_backtrace_buffer, threadback_backtrace_pointers): New static vars. (deliver_thread_signal, deliver_fatal_thread_signal): New functions, for more-accurate delivery of thread-specific signals. (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c. (deliver_arith_signal): Handle in this thread, not in the main thread, since it's triggered by this thread. (maybe_fatal_sig): New function. (init_signals): New arg DUMPING so that we can be more accurate about whether we're dumping. Caller changed. Treat thread-specific signals differently from process-general signals. Block all signals while handling fatal error; that's safer. xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal on IEEE hosts. When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored. Ignore SIGPIPE unless batch. (emacs_backtrace): Output backtrace for the appropriate thread, which is not necessarily the main thread. * src/syssignal.h: Include <stdbool.h>. (emacs_raise): New macro. * src/xterm.c (x_connection_signal): Remove; no longer needed now that we use sigaction. (x_connection_closed): No need to mess with sigmask now. (x_initialize): No need to reset SIGPIPE handler here, since init_signals does this for us now. Fixes: debbugs:12471

(_setjmp, _longjmp): Remove. * src/lisp.h: Include <setjmp.h> here, since we use its symbols here. 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. Fixes: debbugs:12446
* Simplify redefinition of 'abort' (Bug#12316).Paul Eggert2012-09-041-10/+10
| | | | | | | | | | | | | | | | | | | | | | 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.
