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.
* 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

(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.
* lisp/simple.el (async-shell-command-display-buffer): Add
defcustom.
(shell-command): Use the new defcustom to determine whether to show
the buffer immediately, or add a process filter that shows it only
when there is some output.
* etc/NEWS: Document the new variable.
* doc/emacs/misc.texi: Likewise.
Thanks to Juri Linkov and Eli Zaretskii for advice and guidance.
* lisp/dired.el (dired-delete-file): Accept 2 additional answers:
'all', to delete all directories recursively and no prompt anymore.
'quit', to cancel directory deletions (Bug#27940).
Show help message when user inputs 'help'.

so that we can overwrite its global value.
Wrapp the loop within a catch '--delete-cancel to catch when
the user abort the directtry deletion.

* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 26.1):
Announce this change.
Allow Dired to handle calls like
\(dired \"~/foo/*/*.el\"), that is, with wildcards within
the directory part of the file argument (Bug#27631).

(dired-insert-directory): Use the new predicate; when it's true,
handle the directory wildcards with a shell call.
* lisp/eshell/em-ls.el (eshell-ls-use-in-dired): Add/remove both advices.
(eshell-ls-unload-hook): New defun. Use it in
eshell-ls-unload-hook instead of an anonymous function.

* lisp/ls-lisp.el (ls-lisp--dired):
Advice dired to handle wildcards in the directory part with both
eshell-ls and ls-lisp.
