(alarm): No longer a no-op, calls setitimer. src/w32.c (term_ntproc): Call term_timers. (init_ntproc): Make sure all signals are unblocked at startup, to erase any traces of dumping. Call init_timers. src/w32fns.c (hourglass_timer, HOURGLASS_ID): Remove. Windows-specific code to display the hourglass mouse pointer is no longer used. (w32_wnd_proc): Remove code that handled the WM_TIMER message due to hourglass timer expiration. (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY): Remove, no longer used. (w32_note_current_window, show_hourglass, hide_hourglass): New functions, in support of hourglass cursor display similar to other window systems.

| | | | | | | | | | | | | | handling. src/.gdbinit: Set breakpoint on terminate_due_to_signal, not on fatal_error_backtrace. src/w32proc.c (sys_kill): Undo last change: don't do anything when invoked to deliver SIGABRT to our own process. This is now handled by emacs_raise. nt/inc/ms-w32.h (emacs_raise): Redefine to invoke emacs_abort. Fixes: debbugs:12471
* Simplify and avoid signal-handling races.Paul Eggert2012-09-232-0/+8

(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

* Simplify redefinition of 'abort' (Bug#12316).Paul Eggert2012-09-043-10/+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.

* Refactor window-system configurationDaniel Colascione2012-08-312-0/+7
| | | | | | | | | | This change streamlines the window system selection code in configure.in and moves many common function declarations from window-specific headers to frame.h. It introduces a new TERM_HEADER macro in config.h: we set this macro to the right header to use for the window system for which we're compiling Emacs and have source files include it indirectly. This way, we don't have to teach every file about every window system.

* Fix bug #11959 with startup warnings on MS-Windows about ../site-lisp.Eli Zaretskii2012-08-042-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | src/w32.c (init_environment): Change the default values of many environment variables in dflt_envvars[] to NULL, to avoid pushing them into environment when they were not already defined. Remove the code that deletes site-lisp subdirectories from the default value of EMACSLOADPATH, as it is no longer needed. (check_windows_init_file): Now external, not static. Use Vload_path as is, without adding anything, as this function is now called when Vload_path is already set up. src/w32.h (check_windows_init_file): Add prototype. src/emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build directory, ignore the /*/i386/ tail in Vinvocation_directory, for compatibility with Posix platforms. (main): Move the call to check_windows_init_file to here from w32.c. (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if any, in the DEFALT argument into the root of the Emacs build or installation tree, as appropriate. src/callproc.c (init_callproc_1): Call decode_env_path instead of doing its equivalent by hand. (init_callproc): Replace DOS_NT condition with MSDOS, thus letting the code that sets Vexec_path run on MS-Windows. src/lread.c (init_lread): Add comments to #ifdef's. nt/paths.h (PATH_LOADSEARCH, PATH_SITELOADSEARCH, PATH_EXEC) (PATH_DATA, PATH_DOC): Replace dummy directory names with directories relative to %emacs_dir%. (PATH_EXEC): Add lib-src/oo-spd/i386 and lib-src/oo/i386, to cater to the use case of running un-installed Emacs.

(sys_rename): Diagnose renaming of a symlink when the user doesn't have the required privileges. (get_file_security_desc_by_name): Renamed from get_file_security_desc. (stat_worker): New function, with most of the guts of 'stat', and with addition of handling of symlinks and support for 'lstat'. If possible, get file's attributes and security information by handle, not by name. Produce S_IFLNK bit for symlinks, when called from 'lstat'. (stat, lstat): New functions, call 'stat_worker'. (symlink, readlink, careadlinkat): Rewritten to create and resolve symlinks when the underlying filesystem supports them. lib/src/ntlib.c (lstat): New function, calls 'stat'. nt/inc/sys/stat.h (S_IFLNK): Define. (S_ISLNK): A non-trivial definition. (lstat): Prototype instead of a macro that redirects to 'stat'. lisp/files.el (file-truename): Don't skip symlink-chasing part on windows-nt. Incorporate the resolution of 8+3 short aliases on Windows into the loop that recursively chases symlinks. Compare directory and its parent case-insensitively on MS-Windows and MS-DOS. etc/NEWS: Announce the symlink support on MS-Windows.
