* lisp/startup.el (fancy-startup-tail, fancy-startup-screen)
(normal-splash-screen): Adjust for function renaming; move the
storage permissions notice to the top of the splash screen.
* lisp/term/android-win.el (android-after-splash-screen): Rename
from android-before-splash-screen and adjust layout lightly.
* src/android.c (android_wc_lookup_string): Terminate character
composition after a character is returned, whether it contain a
Unicode character or not.
This reverts commit de6b1e1efb.
While it did simplify code, there aren't much in the way of technical
benefits the change at this time, and there were protest against the
unwarranted style change.
Fix some bugs with 'window-state-put' (Bug#69093). Add new
hook 'window-kept-windows-functions' (Bug#68235).
* doc/lispref/windows.texi (Window Configurations): Mention
'window-kept-windows-functions'.
(Window Hooks): Describe new abnormal hook
'window-kept-windows-functions'.
* src/marker.c (Fmarker_last_position): New function to return
the last position of a marker even if its buffer is now dead.
* src/window.c (Fset_window_configuration): If
'window-kept-windows-functions' is non-nil, do not delete any
window whose buffer is now dead but remember all such windows in
a list to pass to 'window-kept-windows-functions'. Run
'window-kept-windows-functions' if it is non-nil.
(Vwindow_kept_windows_functions): New abnormal hook run by
Fset_window_configuration and 'window-state-put' with two
arguments - the frame whose configuration is restored and a list
of entries for each window whose buffer was found dead during
restoration. Each entry is a list of four elements, the window,
the dead buffer, and the last know positions of the start and
point of that window.
* lisp/window.el (window-state-put-kept-windows)
(window-state-put-selected-window): New variables.
(window--state-put-2): Make sure buffer is live before restoring
its state. Set 'window-state-put-selected-window' to state's
selected window. If 'window-kept-windows-functions' is non-nil,
do not delete any windows whose buffer is found dead but
remember all such windows in a list to pass to
'window-kept-windows-functions'.
(window-state-put): Run 'window-kept-windows-functions' if it is
non-nil. Select window recorded in
'window-state-put-selected-window'.
* src/android.c (android_init_key_character_map)
(android_get_dead_char): New functions.
(android_wc_lookup_string): New argument COMPOSE_STATE. Ignore
key events with the COMBINING_ACCENT flag set while recording
their character values there, and combine such characters with
the key event when processing a subsequent key event.
* src/androidgui.h (struct android_compose_status): New
structure.
* src/androidterm.c (handle_one_android_event): Port dead key
combination code from X. (bug#69321)
* src/bidi.c (bidi_resolve_brackets): Move assertion about
'resolved_level' to where it belongs. This avoids unnecessary
aborts when the character is not a bracket type and doesn't need
BPA resolution. (Bug#69421)
* src/xdisp.c (compute_stop_pos): Fix a year-old thinko in
handling auto-composed characters. It was introduced as part
of solving bug#62780, which optimized the search for composable
characters. (Bug#69384)
Previously, the default error handler would correctly suppress
unhandled errors raised when IS_DAEMON and the initial frame
was current, since this is the normal state of operation for a
daemon-mode Emacs. However, this also incorrectly suppressed
errors raised while a daemon-mode Emacs was starting up.
Now, errors raised while a daemon-mode Emacs is starting up will be
handled just like errors when a non-daemon Emacs is starting up.
This was previously the case before changes for bug#1310 and
bug#1836, which added the suppression of errors when IS_DAEMON.
DAEMON_RUNNING didn't exist at the time of those changes, but now
it does, so we can do better.
* src/keyboard.c (Fcommand_error_default_function): Check
!DAEMON_RUNNING in addition to IS_DAEMON. (Bug#68799)
* src/lisp.h (DAEMON_RUNNING): Add a clarifying comment about
what this #define means.
This can improve performance a lot, especially after the obarray has
been fed many symbols.
* src/lread.c (OBARRAY_SIZE): Remove.
(load_path_check): Create an obarray object instead of a vector.
The new opaque type replaces the previous use of vectors for obarrays.
`obarray-make` now returns objects of this type. Functions that take
obarrays continue to accept vectors for compatibility, now just using
their first slot to store an actual obarray object.
obarray-size and obarray-default-size now obsolete.
* lisp/obarray.el (obarray-default-size, obarray-size):
Declare obsolete.
(obarray-make, obarrayp, obarray-clear): Remove from here.
* src/fns.c (reduce_emacs_uint_to_hash_hash): Remove from here.
* src/lisp.h (struct Lisp_Obarray, OBARRAYP, XOBARRAY, CHECK_OBARRAY)
(make_lisp_obarray, obarray_size, check_obarray)
(obarray_iter_t, make_obarray_iter, obarray_iter_at_end)
(obarray_iter_step, obarray_iter_symbol, DOOBARRAY, knuth_hash): New.
(reduce_emacs_uint_to_hash_hash): Moved here.
* src/lread.c (check_obarray): Renamed and reworked as...
(checked_obarray_slow): ...this.
(intern_sym, Funintern, oblookup, map_obarray)
(Finternal__obarray_buckets): Adapt to new type.
(obarray_index, allocate_obarray, make_obarray, grow_obarray)
(obarray_default_bits, Fobarray_make, Fobarrayp, Fobarray_clear): New.
* etc/emacs_lldb.py (Lisp_Object):
* lisp/emacs-lisp/cl-macs.el (`(,type . ,pred)):
* lisp/emacs-lisp/cl-preloaded.el (cl--typeof-types):
* lisp/emacs-lisp/comp-common.el (comp-known-type-specifiers):
* lisp/emacs-lisp/comp.el (comp-known-predicates):
* src/alloc.c (cleanup_vector, process_mark_stack):
* src/data.c (Ftype_of, syms_of_data):
* src/minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
* src/pdumper.c (dump_obarray_buckets, dump_obarray, dump_vectorlike):

* test/lisp/obarray-tests.el (obarrayp-test)
(obarrayp-unchecked-content-test, obarray-make-default-test)
(obarray-make-with-size-test):
Adapt to new type.
* configure.ac (HAVE_INOTIFY): Check for the presence of
inotify_init in addition to inotify_init1.
* src/inotify.c (Finotify_add_watch): Implement with
inotify_init if inotify_init1 is absent.
* src/emacs.c (shut_down_emacs): Remove redundant call to
'eln_load_path_final_clean_up'. We call it from 'kill-emacs'
right before the call to 'exit'.
* src/pdumper.c (pdumper_load): Revert my commit "Pacify GCC
12.1.1 in default developer build" dated 2022-06-13 13:21:18 -07,
as GCC bug 105961 is fixed, and this workaround is not needed for
unfixed GCC as these builds should not use --enable-gcc-warnings.
* src/ccl.c: Do not ignore -Wanalyzer-use-of-uninitialized-value,
as that bug has been fixed in GCC. Ignore
-Wanalyzer-out-of-bounds only if GCC 13, as the bug will
reportedly be fixed when GCC 14 comes out.
Fix gaps in hashing coverage in the middle and end of even fairly short
strings. E.g., `outline-1`, `outline-2` etc all hashed to the exact
same value but with the patch, there are no collisions among the ~160000
symbols in the Emacs tree.
This change also improves average hashing speed by using fewer mixing
operations.
* src/fns.c (hash_string):
Use unit stride for fairly short strings, while retaining the cap of 8
samples for long ones.
Always hash the last word to ensure that the end of the string is
covered. For strings shorter than a word, use fewer loads and a single
reduction step.
* src/lisp.h (XSYMBOL_WITH_POS_SYM, XSYMBOL): Help the compiler by using
eassume instead of eassert for XSYMBOL postconditions likely to be
useful for optimization later. With gcc 13.2 -O2 x86-64 this improved
speed on my usual “compile all .el files” benchmark by 0.7% and shrank
the text size of Emacs by 0.09%.
* src/fns.c (internal_equal): Turn comment into eassert
that !symbols_with_pos_enabled.
(sxhash_obj): Simplify case of symbol with pos (when enabled).
* src/lisp.h (XSYMBOL_WITH_POS_SYM, XSYMBOL_WITH_POS_POS)
(maybe_remove_pos_from_symbol): New inline functions.
(SYMBOL_WITH_POS_SYM, SYMBOL_WITH_POS_POS): Remove.
All uses replaced by the new functions. This avoids some
double-checking in the source code, simplifies the code overall,
and avoids the need for "Type checking is done in the following
macro" comments to explain unusual code.
When configured with --enable-checking and compiled with gcc -O0,
these macros evaluated arguments multiple times, which made it too
easy to mistakenly write code that behaves differently when debugging.
This patch does not affect performance in normal builds.
In --enable-checking builds with gcc -O0 it slows down my usual
benchmark (remove all '*.elc’ files and then 'make') by 4.4%.
I hope that’s good enough; if not I can complicate the macros to
tune better for debugging builds.
* src/lisp.h (lisp_h_SET_SYMBOL_VAL, lisp_h_SYMBOL_VAL)
(lisp_h_XCONS): Remove, moving each definiens to the corresponding
inline function. All uses removed.
* src/lisp.h (lisp_h_PSEUDOVECTORP, lisp_h_EQ, lisp_h_SYMBOLP):
Refactor by removing these macros, moving each definiens to its only
use. Now that we have symbols with position so that there is no longer
a non-lisp_h_* macro counterpart if DEFINE_KEY_OPS_AS_MACROS, there’s
no need to separate these definiens from their inline function bodies.
* src/lisp.h (lisp_h_BASE2_EQ, BASE2_EQ): Remove. All uses
removed. BASE2_EQ was present only for minor optimization and
with current gcc -O2, BASE2_EQ does not affect performance, so
it’s not worth the hassle.
* src/lisp.h (lisp_h_BASE2_EQ, lisp_h_EQ): Simplify and refactor.
On x86-64 with GCC 3.2 this shrinks temacs text by 0.055% and
after removing all *.elc files speeds up 'make' by 1.0%.
* src/lisp.h (lisp_h_BASE2_EQ, lisp_h_EQ):
Simplify by testing symbols_with_pos_enabled first.
On x86-64 with GCC 13.2 this shrinks temacs text by 1.5%
and after removing all *.elc files speeds up 'make' by 1.2%.
