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.
If font-lock-mode is disabled in the current buffer, and
there are no matches for REGEXP, then keep FACE available
for a next search.
* lisp/hi-lock.el (hi-lock-set-pattern): Add FACE into
hi-lock--unused-faces if font-lock-mode is disabled and
there are no matches.
* test/lisp/hi-lock-tests.el (hi-lock-test-set-pattern): Add test.
* test/Makefile.in (test_template): Depend on a .c source file for a
test under lib-src, as for src. (Thanks, Glenn Morris for pointing me
in the right direction.)
* lisp/net/tramp.el (tramp-interrupt-process): Rename from
`tramp-advice-interrupt-process'. Adapt according to changed API.
(top): Add it to `interrupt-process-functions'.
* src/process.c (Finternal_default_interrupt_process): New defun.
(Finterrupt_process): Change implementation, based on
Vinterrupt_process_functions.
(Vinterrupt_process_functions): New defvar.
* test/lisp/net/tramp-tests.el (tramp-test40-unload): Do not
test removal of advice.
* test/lisp/progmodes/python-tests.el
(python-shell-calculate-pythonpath-1): Remove, it merely reprises the
body of `python-shell-calculate-command' and it has been broken on w32
since the fix for Bug#25025 was applied.
* test/src/fileio-tests.el (fileio-tests--symlink-failure):
Be less ambitious about testing non-ASCII chars and encoding
errors, as there are too many portability issues.
* 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.
The auth-source behavior was unclear in some API use cases, so these
extra tests codify and test it. For details see
https://github.com/DamienCassou/auth-password-store/issues/29
* lisp/files.el (make-temp-file): Add new initial TEXT parameter.
* test/lisp/auth-source-tests.el (auth-source-test-searches): Add
auth-source tests and simplify them with the new `make-temp-file'.
* lisp/json.el (json-peek): Reduce to following-char.
(json-pop, json-read): Zero (null char) means end of file.
(json-read-escaped-char): Delimit URL properly.
(json-read-string): Signal error for ASCII control characters.
* test/lisp/json-tests.el (test-json-peek): Check for zero instead of
:json-eof symbol.
(test-json-read-string): New test for control characters in JSON
strings.
* test/lisp/progmodes/elisp-mode-tests.el
(elisp-mode-tests--face-propertized-string): New function.
(elisp--highlight-function-argument-indexed)
(elisp--highlight-function-argument-keyed-1)
(elisp--highlight-function-argument-keyed-2): New tests.
* lisp/textmodes/css-mode.el (css-smie-rules): Provide better support
for indentation of detached rulesets passed to Less mixins.
* test/manual/indent/less-css-mode.less: New file.
The bug with "." and ".." has been present for a while; I
introduced the bug with "" earlier today in my patch for Bug#28023.
* lisp/files.el (make-temp-file): Do not use expand-file-name if
PREFIX is empty or "." or "..", as it does the wrong thing.
Compute absolute-prefix here ...
(files--make-magic-temp-file): ... instead of here ...
* src/fileio.c (Fmake_temp_file_internal): ... or here.
* lisp/files.el (make-temp-file): If the prefix is empty, append
"/" to the absolute prefix so that the new files are children
rather than siblings of temporary-file-directory. This fixes a
bug introduced in the previous change.
* test/lisp/files-tests.el (files-test-make-temp-file-empty-prefix):
New test, for the bug.
* lisp/calendar/todo-mode.el (todo-get-overlay): Wrap in
save-excursion. This fixes a regression introduced by the fix
for bug#27609, whereby trying to raise the priority of the
first item or lower the priority of the last item, which
should be noops, moves point to the item's start. Clarify
comment.
* test/lisp/calendar/todo-mode-tests.el
(todo-test-raise-lower-priority): Add test cases for trying to
raise first item and lower last item.
(with-todo-test): Clear abbreviated-home-dir, since we change HOME.
(todo-test-toggle-item-header02): Remove ":expected-result
:failed" and tests of point after todo-next-item, since the
effect when using Todo mode is not reproducible in the test
environment. Add commentary about this.
* lisp/progmodes/etags.el (visit-tags-table-buffer): Save the current
buffer around the `tags-table-including' calls so as to get buffer
local variables from the right buffer later.
* test/lisp/progmodes/etags-tests.el (etags-visit-tags-table-buffer):
New test.
* test/lisp/progmodes/etags-tests.el (etags-tests--test-dir): New
constant.
(etags-bug-158, etags-bug-23164): Use it so that when running the test
interactively, setting EMACS_TEST_DIRECTORY is not needed.
* src/w32fns.c (syms_of_w32fns) <w32-disable-abort-dialog>: New
variable.
(emacs_abort): If w32-disable-abort-dialog is non-nil, abort right
away, without displaying the Abort dialog, which waits for the user.
* test/src/emacs-module-tests.el (module--test-assertion): Run the
inferior Emacs with the w32 abort dialog disabled. Expect the
status of the aborted Emacs sub-process to be 3 on MS-Windows and
2 on MS-DOS.
* lisp/dired.el (dired--yes-no-all-quit-help): New defun.
(dired-delete-file): Use it. Dont't ask for empty dirs (Bug#27940).
* test/lisp/dired-tests.el (dired-test-with-temp-dirs):
New auxiliar macro.
(dired-test-bug27940): Add new test.
During a `query-replace', the char ',' replaces the character
at point and doesn't move point; right after, the char 'u'
must undo such replacement (Bug#27268).
* lisp/replace.el (replace--push-stack):
New macro extracted from `perform-replace'.
(perform-replace): Use it.
* test/lisp/replace-tests.el (query-replace--undo): Add test.
This prevents definitions being compiled from leaking into the current
Emacs doing the compilation.
* lisp/emacs-lisp/gv.el (gv-define-expander): Use function-put instead
of `put' with `eval-and-compile'.
* test/lisp/emacs-lisp/gv-tests.el: New tests.
* lisp/emacs-lisp/eieio.el (defclass): Use `define-symbol-prop'
instead of `put'.
* test/lisp/emacs-lisp/eieio-tests/eieio-tests.el
(eieio-tests--dummy-function): Remove.
(eieio-test-25-slot-tests, eieio-test-23-inheritance-check): Don't
expect to fail if compiled.
* src/fns.c (syms_of_fns): New variable `overriding-plist-environment'.
(Fget): Consult it.
* lisp/emacs-lisp/bytecomp.el (byte-compile-close-variables): Let-bind
it to nil.
(byte-compile-define-symbol-prop): New function, handles compilation
of top-level `define-symbol-prop' and `function-put' calls by putting
the symbol setting into `overriding-plist-environment'.

* test/lisp/dom-tests.el: Require `subr-x' during runtime as well.
* test/lisp/emacs-lisp/cl-lib-tests.el (cl-lib-defstruct-record):
* test/lisp/emacs-lisp/eieio-tests/eieio-tests.el
(eieio-test-23-inheritance-check, eieio-test-25-slot-tests): Mark as
expected to fail when byte-compiled.
This kludge catches errors caused by evaluating arguments in ert's
should, should-not, and should-error macros; it also catches
macroexpansion errors inside of the above macros (Bug#24402).
* lisp/emacs-lisp/ert.el: (ert--should-signal-hook): New function.
(ert--expand-should-1): Catch macroexpansion errors.
* test/lisp/emacs-lisp/ert-tests.el (ert-test-should-error-argument)
(ert-test-should-error-macroexpansion): Tests for argument and
expansion errors.
Prompted by a problem report by Alex in:
http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00143.html
* src/eval.c (For, Fprogn, Fsetq, FletX, eval_sub):
Compute XCDR (x) near XCAR (x); although this doesn't fix any bugs,
it is likely to run a bit faster with typical hardware caches.
(Fif): Use Fcdr instead of XCDR, to avoid crashing on
self-modifying S-expressions.
(Fsetq, Flet, eval_sub): Count the number of arguments as we go
instead of trusting an Flength prepass, to avoid problems when the
code is self-modifying.
(Fquote, Ffunction, Fdefvar, Fdefconst): Prefer !NILP to CONSP
where either will do. This is mostly to document the fact that
the value must be a proper list. It's also a tiny bit faster on
typical machines nowadays.
(Fdefconst, FletX): Prefer XCAR+XCDR to Fcar+Fcdr when either will do.
(eval_sub): Check that the args are a list as opposed to some
other object that has a length. This prevents e.g. (if . "string")
from making Emacs dump core in some cases.
* test/src/eval-tests.el (eval-tests--if-dot-string)
(eval-tests--let-with-circular-defs, eval-tests--mutating-cond):
New tests.
Positions might change if the length of one dired header line
changes; this happen, for instance, if we add new files.
Instead, line numbers are invariant under shrinks/enlargements
of the file header.
https://lists.gnu.org/archive/html/emacs-devel/2017-07/msg01092.html
* lisp/dired.el (dired-save-positions): Save the line numbers at point.
(dired-restore-positions): Use forward-line to restore the original
position (Bug#27968).
* test/lisp/dired-tests.el (dired-test-bug27968): Add test.
* src/buffer.c (Fgenerate_new_buffer_name): Test IGNORE for being
nil before calling string-equal, since the latter will compare
"nil and 'nil' as equal. (Bug#27966)
* test/src/buffer-tests.el
(test-generate-new-buffer-name-bug27966): New test.
This function must return non-nil for a wildcard like '/*/*.txt'.
* lisp/files.el (insert-directory-wildcard-in-dir-p): Adjust regexp.
* test/lisp/files-tests.el (files-tests--insert-directory-wildcard-in-dir-p):
Add test.
* test/lisp/emacs-lisp/map-tests.el (test-map-elt-testfn)
(test-map-put-testfn-alist): Make sure the lookup key is really non-eq
to the map's key, even if the code is compiled.
Skip the test if Dired use 'ls' emulation with lisp. The same
bug is tested in their respective test suites: ls-lisp-tests.el
and em-ls-tests.el.
* test/lisp/dired-tests.el (dired-test-bug27631): Skip test if 'ls-lisp'
or 'eshell' features are enabled.
* test/lisp/dired-tests.el (dired-test-bug25609): On MS-Windows,
pass temporary files through file-truename, to avoid bogus
failures due to file-name comparison as strings.
