* etc/NEWS: Describe changes.
* lisp/term/ns-win.el (mouse-wheel-scroll-amount,
mouse-wheel-progressive-speed): Set to smarter values for macOS
touchpads.
* src/nsterm.m (emacsView::mouseDown): Use precise scrolling deltas to
calculate scrolling for touchpads and mouse wheels.
(syms_of_nsterm): Add variables 'ns-use-system-mwheel-acceleration',
'ns-touchpad-scroll-line-height' and 'ns-touchpad-use-momentum'.
* src/keyboard.c (make_lispy_event): Pass on .arg when relevant.
* src/termhooks.h (event_kind): Update comments re. WHEEL_EVENT.
* lisp/mwheel.el (mwheel-scroll): Use line count.
* lisp/subr.el (event-line-count): New function.
* src/buffer.c (Foverlays_at): If SORTED is non-nil, reverse the
list of results, to have their order as per the documentation.
(Bug#28390)
* etc/NEWS: Mention the change in the behavior of overlays-at.
* src/xdisp.c (handle_display_spec): If the display property is
wrapped in 'disable-eval' form, disable Lisp evaluation while
processing this property.
(handle_single_display_spec): Accept new argument ENABLE_EVAL_P.
If that argument is false, don't evaluate Lisp while processing
display properties.
* lisp/textmodes/enriched.el
(enriched-allow-eval-in-display-props): New defcustom.
(enriched-decode-display-prop): If
enriched-allow-eval-in-display-props is nil, wrap the display
property with 'disable-eval' to disable Lisp evaluation when the
display property is processed for display. (Bug#28350)
* lisp/gnus/mm-view.el (mm-inline-text): Re-enable processing of
enriched text.
* doc/lispref/display.texi (Display Property): Document the
'disable-eval' wrapping of 'display' properties.
* doc/emacs/text.texi (Enriched Properties): Document
'enriched-allow-eval-in-display-props'.
* etc/NEWS: Describe the security issues with Enriched Text mode
and their solution.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
configure.ac: Add boilerplate for configuring and detecting liblcms2.
etc/NEWS: Mention new configure option and color-distance change.
src/Makefile.in: Add references to lcms.c and liblcms.
src/emacs.c: Define lcms2 symbols.
src/lcms.c: New file.
src/lisp.h: Add declaration for lcms2.
src/xfaces.c: Add optional METRIC argument.
Bug#28412
* lisp/files.el (basic-save-buffer): Re-arrange function so that
write-contents-functions are run earlier. If they return non-nil,
consider the buffer saved without requiring the buffer to be
visiting a file.
(save-some-buffers): This function should consider any buffer with a
buffer-local value for write-contents-functions eligible for
saving.
* test/lisp/files-tests.el (files-test-no-file-write-contents): New
test.
* doc/lispref/files.texi (Saving Buffers): Mention in docs.
* etc/NEWS: And in NEWS.
This also includes changes to if-let and when-let. The single tuple
special case is ambiguous, and binding a symbol to nil is not as
useful as binding it to its value outside the lexical scope of the
binding. (Bug#28254)
* etc/NEWS: Mention.
* lisp/emacs-lisp/subr-x.el (internal--listify):
(internal--build-binding-value-form): Extend to account for
solitary symbols and (EXPR) items in binding varlist.
(if-let*, when-let*): Nix single tuple case and incumbent
bind-symbol-to-nil behavior.
(and-let*): New macro.
(if-let, when-let): Mark obsolete. Redefine in terms of if-let*, so
they implicitly gain the new features without breaking existing code.
* test/lisp/emacs-lisp/subr-x-tests.el: Adjust tests for: lack of
single-tuple special case, lack of binding solitary symbols to nil,
and the introduction of uninterned symbols for (EXPR) bindings. Add
SRFI-2 test suite adapted to Elisp.
The security patches released for Emacs 25.3 were less drastic
than what we had immediately put into master. Adjust master to
match 25.3 (Bug#28350).
* lisp/textmodes/enriched.el (enriched-translations):
Re-enable FUNCTION and display translations that are safe.
(enriched-handle-display-prop): Bring back.
(enriched-decode-display-prop): Bring back, but disable
the unsafe part.
* etc/NEWS: Mention this.
* lisp/thumbs.el (thumbs-rename-images): Treat the destination
as special only if it is a directory name. When there is
a marked list, turn the destination into a directory name
if it is not already.
Change write-file to be consistent with the new behavior
of copy-file, etc.
* etc/NEWS: Mention this.
* lisp/files.el (write-file): Treat the destination as special
only if it is a directory name.
Do the special dance with the destination only if it is a
directory name, for consistency with copy-file etc. (Bug#27986).
* doc/emacs/files.texi (Copying and Naming):
* doc/lispref/files.texi (Create/Delete Dirs):
* etc/NEWS: Document this.
* lisp/files.el (copy-directory): Treat NEWNAME as special
only if it is a directory name.
This changes the behavior of rename-file etc. slightly.
The old behavior mostly disagreed with the documentation, and had
a race condition bug that could allow attackers to modify victims'
write-protected directories (Bug#27986).
* doc/lispref/files.texi (Changing Files): Document that in
rename-file etc., NEWFILE is special if it is a directory name.
* etc/NEWS: Document the change in behavior.
* src/fileio.c (directory_like): Remove. All uses removed.
(expand_cp_target): Test only whether NEWNAME is a directory name,
not whether it is currently a directory. This avoids a race.
(Fcopy_file, Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
Document behavior if NEWNAME is a directory name.
(Frename_file): Simplify now that the destdir behavior occurs
only when NEWNAME is a directory name.
* test/lisp/net/tramp-tests.el (tramp-test11-copy-file)
(tramp-test12-rename-file, tramp--test-check-files):
Adjust tests to match new behavior.
* doc/lispref/files.texi (Truenames): Explain handling of
targets of `file-truename' and `make-symbolic-link', which
look like a remote file name.
* etc/NEWS: Precise examples for symlinks which look like
remote file names. MUSTBENEW of `write-region' is not
propagated to file name handlers.
* etc/NEWS: Mention the type change.
* lisp/descr-text.el (describe-char): Use gethash to access ucs-names.
Hardcode BEL's name into the function instead of needlessly mapping
over the hash table in the spirit of rassoc.
* lisp/international/mule-cmds.el (ucs-names): Fix variable and
function docstrings. Initialize a hash table for ucs-names--the
number of entries is 42845 here. Switch to hash-table
getters/setters.
(mule--ucs-names-annotation): Use hash-table getter.
(char-from-name): Upcase the string if ignore-case is truthy.
* lisp/leim/quail/latin-ltx.el: Use maphash instead of dolist.
* lib-src/emacsclient.c (fail): Parse ALTERNATE_EDITOR, or
corresponding command-line argument, into quote- or space-separated
tokens. If a token starts with a quote, then it naturally is expected
to end with a quote; escaping is not supported. This is enough to cope
with the typical case of requiring the initial path to be quoted,
common on Windows where it may contain spaces.
* etc/NEWS: Document.
* doc/emacs/misc.texi: Likewise.
* doc/man/emacsclient.1: Tweak to remove the implication that only an
editor can be specified (the manual already mentions a “command”).
Fix a small error where “EDITOR” is referred to rather than
“ALTERNATE_EDITOR”.
* test/lib-src/emacsclient-tests.el: Add tests.
* doc/emacs/cmdargs.texi (Initial Options): Document the
'--module-assertions' command-line option.
* doc/lispref/loading.texi (Dynamic Modules): Add a
cross-reference to the description of '--module-assertions'.
* etc/NEWS: Update the NEWS entry for --module-assertions.
Single and double quotes do not have a special meaning in
desktop files.
https://standards.freedesktop.org/desktop-entry-spec/latest/
* etc/NEWS: Mention new mode.
* lisp/files.el (auto-mode-alist): Split out an entry for handling
the .desktop extension with conf-desktop-mode.
* lisp/textmodes/conf-mode.el (conf-desktop-font-lock-keywords): New
variable with rules for booleans and format specifiers.
(conf-unix-mode): Remove desktop file entry example from docstring.
(conf-desktop-mode): New derived major mode.
* src/gtkutil.c (my_log_handler): Don’t define in new versions of
GTK+.
(xg_set_geometry): Always use gtk_window_move in new versions of GTK+.
* src/xterm.c (syms_of_xterm): Document that x-gtk-use-window-move
is ignored.
* lisp/subr.el (x-gtk-use-window-move): Make obsolete.
This lets Emacs deal with arbitrary local symlinks without
mishandling their contents (Bug#28156). For example,
(progn (shell-command "ln -fs '~' 'x'") (rename-file "x" "/tmp/x"))
now consistently creates a symbolic link from '/tmp/x' to '~'.
Formerly, it did that only if the working directory was on the
same filesystem as /tmp; otherwise, it expanded the '~' to
the user's home directory.
* lisp/dired.el (dired-get-filename): Use files--name-absolute-system-p
instead of rolling our own code.
* lisp/files.el (files--name-absolute-system-p): New function.
(file-truename, file-chase-links): Use it to avoid mishandling
symlink contents that begin with ~.
(copy-directory, move-file-to-trash):
Use concat rather than expand-file-name, to avoid mishandling
symlink contents that begin with ~.
* src/fileio.c (Fmake_symbolic_link): Do not expand leading "~" in the
target unless interactive. Strip leading "/:" if interactive.
(emacs_readlinkat): Do not prepend "/:" to the link target if
it starts with "/" and contains ":" before NUL.
* test/src/fileio-tests.el (try-link): Rename from try-char,
and accept a string instead of a char. All uses changed.
(fileio-tests--symlink-failure): Also test leading ~, and "/:",
to test the new behavior.
* doc/lispref/files.texi (File Attributes):
Document file-attributes atomicity.
* etc/NEWS: Document the fix.
* src/dired.c (file_attributes): New args DIRNAME and FILENAME,
for diagnostics. All callers changed. On platforms like
GNU/Linux that support O_PATH, fix a race condition in
file-attributes and similar functions, so that these functions do
not return nonsense if a directory entry is replaced while getting
its attributes. On non-GNU platforms, do a better (though not
perfect) job of detecting the race, and return nil if detected.
* doc/misc/gnus.texi (Non-ASCII Group Names):
* etc/NEWS:
* test/lisp/net/tramp-tests.el (tramp--test-utf8):
Use utf-8-unix, not utf-8, for default-file-name-coding-system, so
that CRLF in file names is left alone.
* lisp/international/mule-cmds.el (set-default-coding-systems):
Do not alter CRLF in file name coding systems.
(prefer-coding-system): Ignore differences in CRLF processing when
checking whether we used the user-specified file name coding system.
* test/src/fileio-tests.el: New file.
* lisp/files.el (make-temp-file): Fix initial TEXT parameter.
(files--make-magic-temp-file): Support optional TEXT parameter.
* etc/NEWS: Document it.
* doc/lispref/files.texi: Document it.
* test/lisp/auth-source-tests.el: Minor reformat.
* etc/NEWS: Add an entry for the new mode.
* lisp/textmodes/less-css-mode.el (less-css): Tweak docstring.
(less-css-lessc-command): Tweak docstring. Don't mark it as
safe. Don't autoload.
(less-css-compile-at-save, less-css-lessc-options)
(less-css-output-directory): Tweak docstrings. Don't autoload.
(less-css-output-file-name): Tweak docstring. Don't mark it as safe.
(less-css-input-file-name): Tweak docstring. Don't autoload.
(less-css-compile-maybe): Use `when' for one-armed `if'.
(less-css--output-path): Tweak docstring.
(less-css--maybe-shell-quote-command): Remove function.
(less-css-compile): Don't autoload. Tweak docstring and message. Fix
compiler warning. Use `string-join' instead of `mapconcat'.
(less-css-font-lock-keywords): Use `font-lock-variable-name-face' for
variables.
(less-css-mode-syntax-table, less-css-mode-map): New variables.
(less-css-mode): Change status line mode name from "LESS" to
"Less". Tweak docstring. Move syntax table definitions to
`less-css-mode-syntax-table'.
(less-css-indent-line): Remove function.
* lisp/faces.el: Define the face.
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-init-header):
* lisp/info.el (Info-fontify-node): Use the new face.
* doc/emacs/display.texi (Standard Faces):
* etc/NEWS: Document the new face. (Bug#28033)
Bug#25354
* lisp/progmodes/compile.el (compilation-num-errors-found): Provide
default value.
(compilation-num-warnings-found, compilation-num-infos-found): New
defvars.
(compilation-mode-line-errors): New defconst.
(compilation-face): Remove.
(compilation-type, compilation--note-type): New functions.
(compilation-parse-errors): Call compilation--note-type.
(compilation-start): Include compilation-mode-line-errors in
mode-line-process.
(compilation-setup): Initialize compilation-num-* variables to 0.
(compilation-handle-exit): Include compilation-mode-line-errors in
mode-line-process.
* doc/emacs/building.texi (Compilation): Document new feature.
