* * image.c (init_tiff_functions, init_imagemagick_functions)Daniel Colascione2012-10-141-3/+3
| | | | | (init_svg_functions): Fix cygw32 build break by using these functions only when WINDOWSNT _and_ HAVE_NTGUI.
* Fix some stat-related races.Paul Eggert2012-10-121-42/+2
| | | | | | | | | | | | * fileio.c (Fwrite_region): Avoid race condition if a file is removed or renamed by some other process immediately after Emacs writes it but before Emacs stats it. Do not assume that stat (or fstat) succeeds. * image.c (slurp_file): Resolve the file name with fopen + fstat rather than stat + fopen. (pbm_read_file) [0]: Remove unused code with stat race. * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]: Remove ineffective code with stat race.

| * Fix last change.Chong Yidong2012-09-231-3/+3
| | | | | | | | * image.c (valid_image_p, make_image): Fix caller to lookup_image_type.
| * Remove LIBRARIES arg from w32_delayed_load and friends.Chong Yidong2012-09-231-63/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These always use Vdynamic_library_alist anyway. * src/image.c (Finit_image_library, lookup_image_type) (define_image_type): Remove now-unneeded second arg. (init_xpm_functions, init_png_functions, init_jpeg_functions) (init_tiff_functions, init_gif_functions, init_svg_functions): Arglist and w32_delayed_load calling convention changed. (gs_type): Remove init_gs_functions; there is no such function. * src/gnutls.c (init_gnutls_functions): Caller changed; remove arg. (Fgnutls_available_p): Caller changed. * src/xml.c (init_libxml2_functions, Flibxml_parse_html_region) (Flibxml_parse_xml_region): Likewise. * src/dispextern.h (struct image_type): Remove arg from init function. * src/w32.c (w32_delayed_load): Remove LIBRARIES argument; always use Vdynamic_library_alist. * lisp/image.el (image-type-available-p): Change caller to init-image-library.
| * Simplify and avoid signal-handling races.Paul Eggert2012-09-231-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * nt/inc/ms-w32.h (emacs_raise): New macro. * src/alloc.c (die): * src/sysdep.c (emacs_abort) [HAVE_NTGUI]: Avoid recursive loop if there's a fatal error in the function itself. * src/atimer.c (pending_atimers): * src/blockinput.h: Don't include "atimer.h"; no longer needed. (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
| * Refactor image-type loading.Chong Yidong2012-09-221-84/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/dispextern.h (struct image_type): Add new slot, storing a type initialization function. * src/image.c (define_image_type): Call the image initializer function if it is defined. Arguments and return value changed. (valid_image_p, make_image): Callers changed. (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type) (gif_type, imagemagick_type, svg_type, gs_type): Add initialization functions. (Finit_image_library): Call lookup_image_type. (CHECK_LIB_AVAILABLE): Macro deleted. (lookup_image_type): Call define_image_type here, rather than via Finit_image_library, and without using CHECK_LIB_AVAILABLE. (syms_of_image): Move define_image_type calls for xbm_type and pbm_type to lookup_image_type.
| * Fix list duplication error in define_image_type.Chong Yidong2012-09-211-1/+7

| * Port _setjmp fix to POSIXish hosts as well as Microsoft.Paul Eggert2012-09-151-3/+1
| | | | | | | | | | | | | | | | | | * nt/config.nt: Attempt to sync with autogen/config.in. (HAVE_SIGSETJMP, HAVE__SETJMP): New macros. (_longjmp, _setjmp): Remove. * src/image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as it's needed on POSIXish hosts that lack _setjmp. Attempt to solve the Microsoft problem in a different way, by altering nt/config.nt.
| * Fix MS-Windows build broken by 2012-09-15T07:06:56Z!eggert@cs.ucla.edu, ↵Eli Zaretskii2012-09-151-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | completing fix for bug #12446. src/w32xfns.c: src/w32uniscribe.c: src/w32term.c: src/w32select.c: src/w32reg.c: src/w32proc.c: src/w32menu.c: src/w32inevt.c: src/w32heap.c: src/w32font.c: src/w32fns.c: src/w32console.c: src/w32.c: src/w16select.c: Remove inclusion of setjmp.h, as it is now included by lisp.h. This completes removal of setjmp.h inclusion erroneously announced in the previous commit. src/lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary more accurate. src/image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is not defined as a macro. The latter happens on MS-Windows.
| * Port better to POSIX hosts lacking _setjmp.Paul Eggert2012-09-151-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols. (_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
| * Work around GCC and GNOME bugs when --enable-gcc-warnings.Paul Eggert2012-09-121-0/+8
| | | | | | | | | | | | | | | | * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify', to work around GNOME bug 683906. * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber. (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp. This works around GCC bug 54561.
| * More fixes for 'volatile' and setjmp/longjmp.Paul Eggert2012-09-121-72/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's. * image.c (struct png_load_context) [HAVE_PNG]: New type. (png_load_body) [HAVE_PNG]: (jpeg_load_body) [HAVE_JPEG]: New function, with most of the old parent function's body. (png_load) [HAVE_PNG]: (jpeg_load) [HAVE_JPEG]: Invoke the new function, to avoid longjmp munging our locals. (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code. (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when longjmp is passed 2, as the C standard doesn't guarantee this. Instead, store the failure code into mgr->failure_code.

| | | | | | | | | | | | | | | | | | | | | | | | | | * lib-src/pop.c (socket_connection) [HAVE_GETADDRINFO]: * src/bidi.c (bidi_push_it, bidi_pop_it): * src/fns.c (copy_hash_table): * src/image.c (define_image_type): * src/keyboard.c (kbd_buffer_store_event_hold): * src/process.c (Fprocess_send_eof): * src/xfaces.c (x_create_gc) [HAVE_NS]: * src/xgselect.c (xg_select): Use assignment, not memcpy, as either will do here, and assignment is more likely to catch type errors.
| * Assume C89 or later for math functions.Paul Eggert2012-09-091-1/+0

That was a problem before C89, but the problem went away many years ago on all practical Emacs targets. * configure.ac (frexp, fmod): Remove checks for these functions, as we now assume them.

C89 or later always defines these. * src/floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN) (in_float, float_error_arg, float_error_arg2, float_error_fn_name) (arith_error, domain_error, domain_error2): Remove all this pre-C89 cruft. Do not include <errno.h> as that's no longer needed -- we simply return what C returns. All uses removed. (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with the wrapped code. (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2): Remove. All uses expanded, as these macros are no longer used more than once and are now more trouble than they're worth. (Ftan): Use tan, not sin / cos. (Flogb): Assume C89 frexp. (fmod_float): Assume C89 fmod. (matherr) [HAVE_MATHERR]: Remove; no longer needed. (init_floatfns): Remove. All uses removed.
| * Simplify redefinition of 'abort' (Bug#12316).Paul Eggert2012-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * Be more systematic about _setjmp vs setjmp.Paul Eggert2012-09-031-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | * alloc.c (test_setjmp, mark_stack): * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]: (png_load, my_error_exit, jpeg_load): * process.c (send_process_trap, send_process): Uniformly prefer _setjmp and _longjmp to setjmp and longjmp. The underscored versions are up to 30x faster on some hosts. Formerly, the code used setjmp+longjmp sometimes and _setjmp+_longjmp at other times, with no particular reason to prefer setjmp+longjmp.

That way, we're more likely to catch errors if the interfaces change. * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not declare xg_mark_data. * dispextern.h (x_frame_parm_handlers): * font.h (Qxft): * lisp.h (Qlexical_binding, Qinternal_interpreter_environment) (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold) (Qultra_bold, Qoblique, Qitalic): Move extern decl here from .c file. * alloc.c (xg_mark_data) [USE_GTK]: * doc.c (Qclosure): * eval.c (Qlexical_binding): * fns.c (time) [!HAVE_UNISTD_H]: * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light) (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic): * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]: * lread.c (Qinternal_interpreter_environment): * minibuf.c (Qbuffer): * process.c (QCfamily, QCfilter): * widget.c (free_frame_faces): * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]: * xfont.c (x_clear_errors): * xterm.c (x_frame_parm_handlers): Remove now-redundant extern decls. * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]: * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic): Now static. * xfaces.c: Remove unnecessary static decls. * xterm.c (updating_frame): Remove decl of nonexistent object.
* | Implement cygw32Daniel Colascione2012-09-171-22/+40
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Here, we use the generic window-system configuration system we just implemented to support the w32 window-system in the mainline build under Cygwin. (Previously, the w32 window system could only be compiled as part of the NT-native Emacs build process.) The changes in this patch need to be applied atomically in order to avoid breaking Emacs. The changes include: - Changes throughout the Lisp and C code to not assume that NT Emacs and the w32 window system are synonymous. - Wiring up the regular select(2) event loop to Windows messages - Cleaning up the w32 drag-and-drop receiving code. - Exposing Cygwin path conversion functions to elisp. - Unicode file dialog support when compiling for Cygwin. - Splitting the w32 term lisp initialization code into code applicable to any w32 window-system and code specific to system-type windows-nt. - Integrating the old and new w32 code into the build system.
* Fix last changes related to w32 and Cygwin.Eli Zaretskii2012-09-011-0/+1
| | | | | | src/image.c: Restore mistakenly removed inclusion of w32.h. Without it, GCC doesn't see prototypes of w32_delayed_load, and complains about implicit conversions from integer to pointer.
* Refactor window-system configurationDaniel Colascione2012-08-311-19/+12
| | | | | | | | | | 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.
