The old calculation relied on a hodgpodge of partly updated GC
stats to find a number to multiply gc-cons-percentage by.
The new one counts data found by the previous GC, plus half of
the data allocated since then; this is more systematic albeit
still ad hoc.
* src/alloc.c (consing_until_gc, gc_threshold, consing_threshold):
Now EMACS_INT, not intmax_t.
(HI_THRESHOLD): New macro.
(tally_consing): New function.
(make_interval, allocate_string, allocate_string_data)
(make_float, free_cons, allocate_vectorlike, Fmake_symbol): Use it.
(allow_garbage_collection, inhibit_garbage_collection)
(consing_threshold, garbage_collect):
Use HI_THRESHOLD rather than INTMAX_MAX.
(consing_threshold): New arg SINCE_GC. All callers changed.
(bump_consing_until_gc): Return new consing_until_gc, instead of
nil. All callers changed. Don’t worry about overflow since we
now saturate at HI_THRESHOLD. Guess that half of
recently-allocated objects are still alive, instead of relying on
the previous (even less-accurate) hodgepodge.
(maybe_garbage_collect): New function.
(garbage_collect): Work even if a finalizer disables or enables
memory profiling. Do not use malloc_probe if GC reclaimed nothing.
* src/lisp.h (maybe_gc): Call maybe_garbage_collect instead
of garbage_collect.
* src/alloc.c (make_interval, allocate_string, make_float)
(free_cons, Fcons, setup_on_free_list)
(allocate_vector_from_block, Fmake_symbol):
Do not update gcstat, since it is for statistics from the most
recent GC, not for a partially-updated hodgepodge.
(sweep_vectors): Update gcstat, since setup_on_free_list
no longer does.
(garbage_collect_1): Rename to garbage_collect and adopt its API.
Remove the old garbage_collect, which is no longer needed.
All callers changed.
There are only a few users of print-number-table, and none of them use
it when print-circle is nil. A couple of them used to. print_object
was changed in 2012-04-20 "* src/print.c (print_preprocess): Only
check print_depth if print-circle is nil".
byte-compile-output-docform which uses print-number-table binds
print-circle to t before printing unless
byte-compile-disable-print-circle is set, but that variable has been
marked obsolete since 24.1.
* src/print.c (print_preprocess): Assert Vprint_circle is non-nil.
Remove code handling the case when Vprint_circle is nil.
(print, Fprint_preprocess): Don't call print_preprocess unless
Vprint_circle is non-nil.
(print_object): Remove comment referencing removed code in
print_preprocess.
cl-prin1 prints all its punctuation by passing strings to prin1. When
print-circle was set, print_preprocess was creating a new hash table
for each string, causing excessive garbage collection when printing
large Lisp objects with cl-prin1.
* src/print.c (print_number_index): Fix typo in comment above.
(PRINT_CIRCLE_CANDIDATE_P): Don't create print_number_table
for top-level strings with no properties, except when
print_continuous_numbering is on.
* lisp/emacs-lisp/cl-print.el (cl-print-to-string-with-limit): Reduce
print-level and print-length more quickly when the structure being
printed is very large.
* lisp/emacs-lisp/backtrace.el (backtrace-view): Mention
:print-gensym in docstring.
(backtrace-mode-map): Add keyboard binding for
backtrace-toggle-print-gensym. Add menu entries for
backtrace-toggle-print-circle and backtrace-toggle-print-gensym.
(backtrace--with-output-variables): Bind print-gensym with value
of :print-gensym found in view plist.
(backtrace-toggle-print-circle): Remove description of
implementation details from docstring.
(backtrace-toggle-print-gensym): New command.
(backtrace--toggle-feature): Add echo area message describing result
of command.
* test/lisp/emacs-lisp/backtrace-tests.el
(backtrace-tests--print-circle): New test.
* doc/lispref/debugging.texi (Backtraces): Document keyboard
binding for backtrace-toggle-print-gensym.
* test/lisp/net/tramp-tests.el (tramp-test33-environment-variables):
Use ${parameter:-word} construct. Remove PS1 entry from
"printenv" output.
(tramp--test-check-files): Use "printenv".
* src/xdisp.c (tool_bar_height, redisplay_tool_bar)
(display_menu_bar): If the Lisp string to be displayed in the
menu-bar or tool-bar window is multibyte, tell the display
engine to treat it as multibyte, instead of relying on the
initial determination by init_iterator (which is based on the
multibyteness of the current buffer). (Bug#37385)
* lisp/calc/calc-prog.el (calc-user-define-permanent): Correctly save
the composition when the user specifies their formula by its command
name or key.
Copyright-paperwork-exempt: yes
* lisp/progmodes/python.el (python-do-auto-fill): New function.
(python-mode): Set it as normal-auto-fill-function, and don't set
fill-indent-according-to-mode. Having the latter set during
fill-paragraph gives wrongs result, because python-indent-line doesn't
remove indentation added by filling.
* test/lisp/progmodes/python-tests.el (python-fill-docstring): New
test.
(sh-shell-initialize-variables): Use sh--assignment-collect on
post-self-insert-hook instead.
(sh--assignment-collect): New function, extracted from sh-assignment.
(sh-assignment): Use it and mark as obsolete.
* lisp/isearch.el (isearch-yank-until-char): New function.
(isearch-mode-map, isearch-menu-bar-yank-map): Add it.
(isearch-forward): Document the new binding.
* doc/emacs/search.texi (Isearch Yanking): Document the feature.
* etc/NEWS: Mention the above.
* lisp/net/tramp-adb.el (tramp-adb-maybe-open-connection):
* lisp/net/tramp-gvfs.el (tramp-gvfs-maybe-open-connection):
* lisp/net/tramp-rclone.el (tramp-rclone-maybe-open-connection):
* lisp/net/tramp-sh.el (tramp-maybe-open-connection):
* lisp/net/tramp-smb.el (tramp-smb-maybe-open-connection):
* lisp/net/tramp-sudoedit.el (tramp-sudoedit-maybe-open-connection):
Throw `non-essential' at the beginning of the function.
* lisp/net/tramp.el (tramp-handle-file-exists-p):
* lisp/net/tramp-sh.el (tramp-sh-handle-file-exists-p):
* lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-file-exists-p):
Run only when host is connectable. This is due to host name
completion, which shall be optimized.
* lisp/net/tramp-smb.el (tramp-smb-do-file-attributes-with-stat)
(tramp-smb-get-file-entries): Access connection buffer only after
sending the command.
* lisp/net/tramp.el (tramp-get-buffer, tramp-get-connection-buffer):
New argument DONT-CREATE.
(tramp-message): Use it.
(tramp-get-mutex): Check, whether host is connectable.
(tramp-file-name-handler): Set thread only when host is connectable.
(tramp-connectable-p): Allow also VEC as argument.
(tramp-completion-handle-file-name-completion): Do not expand directory.
Now that "key == Qunbound" is used to determine if a hash table entry
is available, we can't stash pre-allocated vectors into the `key` slot
anymore, so use the `value` slot instead.
(make_log): Pre-fill the `value` slots i.s.o `key`.
(evict_lower_half): Stash key back into `value`, i.s.o `key`.
(record_backtrace): Get pre-allocated vector for `value` i.s.o `key`.
* src/dired.c (directory_files_internal): Fix race condition:
when some other process removed a file between the readdir and
the ensuing lstat, directory-files-and-attributes would return
a list containing nil.
* src/callproc.c (encode_current_directory): Remove redundant
call to Ffile_accessible_directory_p. The code checks the
encoded name with file_accessible_directory_p anyway.
* src/alloc.c (memory_full): Just report "memory exhausted" if
failure occurs during initialization, since fancier recovery
schemes are not likely to work when not initialized.
* src/emacs.c (dump_error_to_string): Accept int, not enum
pdumper_load_result, since the result might not fit in the
enum. Use strerror if it was derived from errno. This is for
better diagnostics of pdump load failures.
(load_pdump_find_executable): Return char *, not enum. 2nd
arg is now pointer to buffer size, rather than pointer to
pointer to buffer. All callers changed. Use Emacs allocator
since they should now be OK even during early startup.
Use check_executable instead access, to use effective rather
than real permissions.
(load_pdump): Return void since callers ignore result.
Use int where enum could be too narrow. Use heap rather
than stack for possibly-long string. Prefer ptrdiff_t to
size_t.
* src/fileio.c (check_executable): Now extern.
* src/pdumper.c (pdumper_load): Return int that may have
errno added to it, for better diagnostics when loads fail.
Problem reported by Leonard Lausen (Bug#37331).
* src/dbusbind.c: Include pdumper.h.
(syms_of_dbusbind_for_pdumper):
New function, to reset the registered buses.
(syms_of_dbusbind): Use it, fixing a TODO.
* lisp/gnus/gnus-art.el (gnus-mime-inline-part)
(gnus-mm-display-part, gnus-mime-buttonize-attachments-in-header):
Create a new overlay used to mark Attachment header instead of
using existing overlays.
* lisp/emacs-lisp/autoload.el (make-autoload): Add `cl-defstruct' to
"complex cases" list.
* lisp/emacs-lisp/cl-macs.el (cl-defstruct): Add :autoload-end to
limit what is declared in autoloads.el for a defstruct.
* lisp/calendar/icalendar.el (icalendar--convert-ical-to-diary): Set
start time only if it is explicitly given in ical. Do not use
start-time as default for end-time (Bug#33277).
* test/lisp/calendar/icalendar-tests.el (icalendar-import-bug-33277):
New. Test fix for Bug#33277.
* lisp/tmm.el (tmm-prompt): Don't duplicate items of tmm--history.
Don't reverse tmm-km-list for completion. Don't set the initial
position of 'tmm--history. Use reverse tmm--history as the list
of default values for M-n.
(tmm-add-prompt): Don't insert initial value to the minibuffer.
* lisp/progmodes/compile.el (compilation--margin-string): Renamed from
compilation-margin-string. Use defconst rather than defvar. Use propertize
rather than a separate put-text-property. Trim the doc string.
* test/lisp/shadowfile-tests.el (shadow-test08-shadow-todo)
(shadow-test09-shadow-copy-files): Use truename of
`shadow-test-remote-temporary-file-directory'. (Bug#37202)
Problem reported by Michael Heerdegen (Bug#37321).
* src/alloc.c (gc_threshold): New static var.
(bump_consing_until_gc): Change args from DIFF to THRESHOLD and
PERCENTAGE. All uses changed. When accounting for a changed
gc-cons-percentage, do not assume that total_bytes_of_live_objects
returns the same value now that it did the last time we were
called.
* lisp/emacs-lisp/bytecomp.el (byte-compile-maybe-guarded): Add
arguments to local-variable-p to the bound list.
* lisp/image-mode.el (image-toggle-display-image): Remove no longer
needed boundp check.
* list/progmodes/flymake-proc.el (flymake-proc-create-temp-inplace):
Include a time string part (hour + minute + second + nanosecond) in
the temporary name to make it unique enough.
(flymake-proc-legacy-flymake): Store temporary file names in the
process for usage in the sentinel.
(flymake-proc--process-sentinel): Bind values of temporary file names
dynamically to values stored in the process so that the cleanup
function will delete the correct temporary file(s).
Fixes bug#31981.
