Problem reported by Alexander Kuleshov in:
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg01289.html
* src/gtkutil.c (xg_get_page_setup):
Use switch rather than if-then-else.
* src/image.c (COLOR_TABLE_SUPPORT):
Define directly rather than via #define and optional later #undef.
(lookup_rgb_color) [USE_CAIRO && ENABLE_CHECKING]:
Crash when the pixel is undefined, as there is a genuine bug
here (Bug#22442).
* src/image.c (tiff_load, gif_load, svg_load_image)
(x_kill_gs_process) [USE_CAIRO]:
* src/xterm.c (x_draw_fringe_bitmap) [USE_CAIRO]:
Omit unused locals, or move them to where they’re needed.
(x_clear_area1): Now ATTRIBUTE_UNUSED.
* src/xdisp.c (dump_glyph): Redo the call to fprintf to avoid
putting #if inside the arguments to a standard function, which
the C standard says has undefined behavior.
Adjust the newly-added Xwidgets code so that it uses a more-typical
Emacs style. This should not affect behavior, except that in
a few places it adds runtime checks that Lisp arguments are of
the proper type, and in one place it uses more-precise arithmetic.
* src/buffer.c, src/dispnew.c, src/emacs.c, src/emacsgtkfixed.c:
* src/emacs.c, src/print.c, src/window.c, src/xdisp.c, src/xterm.c:
Include xwidget.h unconditionally.
* src/buffer.c (Fkill_buffer):
* src/dispnew.c (update_window):
* src/emacs.c (main):
* src/print.c (print_object):
* src/window.c (Fdelete_window_internal):
* src/xdisp.c (handle_single_display_spec, push_it, pop_it)
(get_next_element, set_iterator_to_next, next_element_from_xwidget)
(dump_glyph, calc_pixel_width_or_height, BUILD_GLYPH_STRINGS_XW)
(BUILD_GLYPH_STRINGS, x_produce_glyphs, get_window_cursor_type):
* src/xterm.c (x_draw_glyph_string, x_draw_bar_cursor):
Call xwidget functions and macros without worrying about
HAVE_XWIDGETS when the code is a no-op on non-xwidget
platforms.
* src/dispextern.h (XWIDGET_GLYPH, struct glyph_string.xwidget)
(IT_XWIDGET, GET_FROM_XWIDGET, struct it.u.xwidget)
(struct it.xwidget):
* src/lisp.h (PVEC_XWIDGET, PVEC_XWIDGET_VIEW):
Always define.
* src/emacsgtkfixed.h: Omit unnecessary comment.
* src/keyboard.c: Fix spacing.
* src/xdisp.c (BUILD_XWIDGET_GLYPH_STRING, produce_xwidget_glyph):
Define to be a no-op if not HAVE_XWIDGETS.
* src/xwidget.c: Include xwidget.h first (after config.h)
to make sure that it can stand by itself.
(Fmake_xwidget, Fxwidget_webkit_execute_script):
Fix typo in doc string.
(Fmake_xwidget): Check type of args.
(Fmake_xwidget, offscreen_damage_event)
(webkit_document_load_finished_cb, webkit_download_cb)
(webkit_new_window_policy_decision_requested_cb)
(webkit_navigation_policy_decision_requested_cb)
(xwidget_osr_draw_cb, xwidget_osr_event_forward)

Omit unnecessary casts.
* src/xwidget.c (Fmake_xwidget, xwidget_hidden)
(xwidget_show_view, xwidget_hide_view)
(x_draw_xwidget_glyph_string, xwidget_start_redisplay, xwidget_touch)
(xwidget_touched):
* src/xwidget.h (struct xwidget.kill_without_query)
(struct xwidget_view.redisplayed, struct xwidget_view.hidden):
Use bool for boolean.
* src/xwidget.c (store_xwidget_event_string, Fxwidget_size_request):
Simplify by using list functions.
(WEBKIT_FN_INIT): Omit unnecessary test for nil.
(Fxwidget_resize): Check type of integer args
before doing any work. Check that they are nonnegative.
(Fxwidget_set_adjustment): Check type of integer arg.
Avoid redundant call to gtk_scrolled_window_get_vadjustment.
Simplify. Use double, not float.
(Fxwidget_info, Fxwidget_view_info): Simplify by using CALLN.
(valid_xwidget_spec_p): Simplify.
(xwidget_spec_value): Omit unused arg FOUND. All callers changed.
* src/xwidget.h: Include lisp.h first, so that includers do
not need to worry about doing that before including this file.
Make this .h file safe to include even on non-HAVE_XWIDGETS
configurations, to simplify the includers.
(x_draw_xwidget_glyph_string, syms_of_xwidget, valid_xwidget_spec_p)
(xwidget_end_redisplay, lookup_xwidget)
(xwidget_view_delete_all_in_window, kill_buffer_xwidgets):
Now a no-op if !HAVE_XWIDGETS, to simplify callers.
(struct glyph_matrix, struct glyph_string, struct xwidget)
(struct xwidget_view, struct window):
New forward or incomplete decls, so that includers need not
assume the corresponding .h files are already included, or that
HAVE_XWIDGETS is defined.
(struct xwidget_type, xwidget_from_id): Remove; unused.
* configure.ac (--with-file-notification): Add kqueue.
(top): Remove special test for "${HAVE_NS}" and
${with_file_notification}, this is handled inside gfilenotify
tests. Add kqueue tests. Use NOTIFY_CFLAGS and NOTIFY_LIBS
instead of library specific variables. Add error message for
gfile on Nextstep.
* doc/lispref/os.texi (File Notifications): Add kqueue as backend.
Fix some glitches in the example.
* etc/NEWS: Mention kqueue.
* lisp/filenotify.el (file-notify--library)
(file-notify-descriptors, file-notify-callback)
(file-notify-add-watch, file-notify-rm-watch)
(file-notify-valid-p): Add kqueue support.
(file-notify--rm-descriptor): Remove WHAT arg.
* src/Makefile.in: Use NOTIFY_CFLAGS and NOTIFY_LIBS.
* src/emacs.c (main): Call globals_of_kqueue and syms_of_kqueue.
* src/inotify.c (inotifyevent_to_event): Extract file name from
watch_object if the event doesn't provide it.
(Finotify_add_watch): Add file name to watch_object.
* src/keyboard.c (make_lispy_event): Check also for HAVE_KQUEUE.
* src/kqueue.c: New file.
* src/lisp.h: Declare extern globals_of_kqueue and syms_of_kqueue.
* test/automated/file-notify-tests.el
(file-notify--test-expected-events): Remove.
(file-notify--test-cleanup): Do not set that variable.
(file-notify--test-timeout) Use different timeouts for
different libraries.
(file-notify--test-library): New defun.
(file-notify--test-event-test): Make stronger checks.
(file-notify--test-with-events): EVENTS can also be a list of
lists. Flush outstanding events before running the body.
Make timeout heuristically depend on the number of events.
(file-notify-test01-add-watch, file-notify-test02-events)
(file-notify-test04-file-validity, file-notify-test05-dir-validity):
Rewrite in order to call file monitors but directory monitors.
(file-notify-test02-events, file-notify-test04-file-validity): Do
not skip cygwin tests. Add additional test for file creation.
Adapt expected result for different backends.
(file-notify-test03-autorevert): Some of the tests don't work for
w32notify.
(file-notify-test06-many-events): New test.
These were recently added, mostly as part of xwidget code.
* src/emacsgtkfixed.c (emacs_fixed_get_type): Now static.
(EMACS_FIXED, EMACS_FIXED_GET_CLASS):
Now static functions here, not macros in emacsgtkfixed.h.
* src/emacsgtkfixed.h (EMACS_TYPE_FIXED):
Remove. All uses replaced by definiens.
(EMACS_FIXED, EMACS_FIXED_GET_CLASS):
Remove; these are now static functions in emacsgtkfixed.c.
(EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS):
Remove; unused.
(emacs_fixed_get_type): Remove decl; no longer extern.
* src/xwidget.c (offscreen_damage_event)
(webkit_mime_type_policy_typedecision_requested_cb)
(webkit_new_window_policy_decision_requested_cb)
(webkit_navigation_policy_decision_requested_cb)
(xwidget_spec_value, xwidget_view_lookup)
(xwidget_start_redisplay, xwidget_touch):
Now static.
* src/xwidget.h (xwidget_start_redisplay, xwidget_touch):
Remove decls.
I ran into this problem on my Fedora 23 installation;
Emacs configured but did not build when --with-xwidgets was specified.
* configure.ac (HAVE_WEBKIT, HAVE_GIR): Omit unnecessary initializations.
(DOES_XWIDGETS_USE_GIR): New var.
If --with-xwidgets is specified, report an error if not
doable, to be consistent with the other --with options.
Require webkitgtk3 to use Xwidgets, as the Xwidgets code does
not work at all without webkitgtk3. Simplify use of
EMACS_CHECK_MODULES. Output message about gobject
introspection only if xwidgets are used.
* etc/NEWS: Users need webkitgtk3, not merely webkit.
* src/xwidget.c (syms_of_xwidget): Don’t worry about HAVE_WEBKIT_OSR,
since this file is no longer compiled if webkitgtk3 is not available.
* src/window.c (window_scroll_line_based): When setting point to
preserve screen coordinates, don't let cursor enter either of the
two scroll margins. (Bug#22395)
* src/window.c (window_scroll_pixel_based): When setting point to
preserve screen coordinates, don't let cursor enter either of the
two scroll margins. Fix incorrect usage of
WINDOW_WANTS_HEADER_LINE_P and use WINDOW_HEADER_LINE_HEIGHT
instead of CURRENT_HEADER_LINE_HEIGHT. (Bug#22395)
* src/gnutls.c (emacs_gnutls_global_init): Now extern.
Don’t set gnutls_global_initialized if gnutls_global_init fails.
* src/sysdep.c: Include "gnutls.h", and <gnutls/crypto.h>
if 2.12 or later, which has gnutls_rnd.
(emacs_gnutls_global_init, gnutls_rnd): New fallback
placeholder macros if before 2.12.
(init_random): Initialize gnutls globals before trying to
use gnutls_rnd.
The OpenBSD C compiler issues false alarms about strcpy, strcat, and
sprintf, and this messes up 'configure' when it tests for the cleanup
attribute. Work around the problem by using __has_attribute directly.
Problem reported by Joakim Jalap (Bug#22385).
* configure.ac: Don’t use AX_GCC_VAR_ATTRIBUTE.
* m4/ax_gcc_var_attribute.m4: Remove.
* src/conf_post.h (__has_attribute): Provide a substitute, for
non-GCC or older GCC compilers. All uses changed to assume
the substitute. Check for the cleanup attribute.
* src/emacs-module.c (module_has_cleanup): Just use __has_attribute.
This attempts to improve on the fix for Bug#22202.
* configure.ac (HAVE_DEV_URANDOM): Remove.
Check /dev/urandom existence at run time, not at build time,
since the device could exist in the former but not the latter.
* src/sysdep.c [HAVE_GNUTLS]: Include gnutls/gnutls.h.
(gnutls_rnd) [GNUTLS_VERSION_NUMBER < 0x020c00]: New fallback macro.
(random_seed): New typedef.
(set_random_seed): New static function.
(seed_random): Use them.
(init_random): Use random_seed instead of uintmax_t, so as to
not consume more entropy than needed. Prefer gnutls_rnd if it
works; this avoids a redundant open of /dev/urandom on
GNU/Linux with modern GnuTLS.
* src/w32.c <multiByteToWideCharFlags>: New global variable.
(filename_to_utf16, filename_from_ansi, check_windows_init_file):
Use it instead of the literal MB_ERR_INVALID_CHARS.
(maybe_load_unicows_dll): Initialize multiByteToWideCharFlags as
appropriate for the underlying OS version. For details, see
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00835.html.
* src/w32.h: Declare multiByteToWideCharFlags.
* src/w32fns.c (Fx_file_dialog, Fw32_shell_execute)
(add_tray_notification): Use multiByteToWideCharFlags instead of
the literal MB_ERR_INVALID_CHARS.
(_resetstkoflw_proc): New typedef.
(w32_reset_stack_overflow_guard): Call _resetstkoflw via a
pointer, as this function is absent in msvcrt.dll shipped with W2K
and older systems.
Copyright-paperwork-exempt: yes
* src/w32heap.c (init_heap): Redirect malloc, realloc, and free to
special functions on Windows 9X. Refuse to dump Emacs on Windows 9X.
(malloc_after_dump_9x, realloc_after_dump_9x)
(free_after_dump_9x): New functions. (Bug#22379) See also
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00852.html
for more details about the original problem.
* nt/inc/ms-w32.h (malloc_after_dump_9x, realloc_after_dump_9x)
(free_after_dump_9x): Add prototypes.
Copyright-paperwork-exempt: yes
* configure.ac: Check for "/dev/urandom".
* src/sysdep.c (init_random) [HAVE_DEV_URANDOM]: Read the stream
for the seed from "/dev/urandom".
[WINDOWSNT]: Obtain the stream for the seed from w32 APIs.
* src/fns.c (Frandom): Update the doc string to indicate that
system entropy is used when available.
* src/w32.c: Include wincrypt.h.
(w32_init_crypt_random, w32_init_random): New functions, use the
CryptGenRandom API.
(globals_of_w32): Initialize w32_crypto_hprov handle to zero.
* src/w32.h (w32_init_random): Add prototype.
* doc/lispref/numbers.texi (Random Numbers): Document more details
about 't' as the argument to 'random'.
* etc/NEWS: Mention that '(random t)' now uses a cryptographically
strong seed if possible.
(Bug#22202)
* src/w32.c (sys_write): Don't write to a pipe more stuff than its
buffer can hold. Don't return -1 if something has been written to
the pipe. Zero out 'errno' before calling '_write', to avoid
returning a stale value. (Bug#22344)
* src/w32proc.c (syms_of_ntproc) <w32-pipe-buffer-size>: New variable.
* src/w32.c (pipe2): Use it to request a user-defined size for the
pipe being created.
* etc/NEWS: Mention 'w32-pipe-buffer-size'.
* doc/emacs/msdos.texi (Windows Processes): Document
'w32-pipe-buffer-size'.
* src/alloc.c (garbage_collect_1): Don't bother saving and
restoring the echo-area message if we are GC'ing after running out
of memory. This avoids an infloop due to repeated attempts to
allocate memory for the cons cell needed to save the message,
which signals the memory-full error, which attempts to save the
echo-area message, which signals memory-full again, etc.
* src/w32.c (map_w32_filename): Avoid non-trivial system calls for
the benefit of FAT volumes if we are called as part of shutting
down due to a fatal error, which probably means we are trying to
auto-save the session.
* src/lread.c (check_obarray): Don't bother making the obarray
valid if we are shutting down due to a fatal error. This avoids
interfering with auto-saving the crashed session.
* src/alloc.c (HAVE_MODULES): Now a constant 0 if not defined,
so that later code can use 'if' rather than '#ifdef'.
(mark_maybe_pointer): Simplify based on HAVE_MODULES now
always working.
This use of 'noexcept' runs afoul of the C++11 standard.
Problem reported by Philipp Stephani in:
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00706.html
* src/emacs-module.c (emacs_finalizer_function):
Move this typedef here ...
* src/emacs-module.h: ... from here, and use only the C
version of the typedef. The typedef is now private since it
is never used in the .h file now and anyway it seemed to be
causing more confusion than it cured.
(make_user_ptr, get_user_finalizer, set_user_finalizer):
Open-code the type instead.
* src/xdisp.c (setup_for_ellipsis): Use the face of the preceding
text in it->saved_face_id for displaying the ellipsis, and ignore
the face, if any, of the invisible text. (Bug#22320)
* src/print.c (printchar_to_stream):
* src/xdisp.c (message_to_stderr): If coding-system-for-write has
a non-nil value, use it to encode output in preference to
locale-coding-system. See the discussions in
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00048.html
for the details.
* doc/lispref/os.texi (Terminal Output): Document how to send
non-ASCII text via 'send-string-to-terminal'.
(Batch Mode): Document how text written to standard streams is
encoded. Fix inaccuracy regarding which output streams are used
by output functions in batch mode.
* src/buffer.c (syms_of_buffer): Reword doc string to avoid confusion.
The value 'lambda (literally) can be interpreted as (quote lambda),
which is not intended here; we want just the lambda symbol.
* admin/merge-gnulib (GNULIB_MODULES): Add ignore-value.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/ignore-value.h: New file, from gnulib.
* src/keyboard.c: Include it.
(write_stdout, read_stdin): New functions.
(handle_interrupt): Use them instead of printf and getchar,
and avoid fflush when handling signals.
* src/nsterm.m (EmacsBell): Add feature to remove visual bell
unconditionally.
(hide_bell): New function.
(ns_copy_bits): Hide visible bell before scrolling the frame content.
