These changes remove some assumptions of Lisp code on timestamp
format. Although we’re not going to change the default format any
time soon, I went looking for code that was too intimate about
details of timestamp format and removed assumptions where this was
easy to do with current Emacs primitives.
* lisp/ido.el (ido-wash-history):
Fix test for zero timestamp.
* lisp/time.el (display-time-event-handler):
Use time-less-p rather than doing it by hand.
(display-time-update): Simplify by using float-time
instead of doing the equivalent by hand.
* lisp/url/url-auth.el (url-digest-auth-make-cnonce):
* test/lisp/calendar/parse-time-tests.el (parse-time-tests):
* test/lisp/emacs-lisp/timer-tests.el (timer-test-multiple-of-time):
* test/lisp/net/tramp-tests.el:
(tramp-test19-directory-files-and-attributes)
(tramp-test22-file-times, tramp-test23-visited-file-modtime):
Don’t assume detailed format of returned Lisp timestamps.
Formerly nil meant both that DST was not in effect and that
the DST flag was unknown, and different functions interpreted
the flag differently. Now the meaning is consistently nil for
DST not in effect, and -1 for DST flag not known.
* doc/lispref/os.texi (Time Conversion): The DST slot is
now three-valued, not two-.
* doc/misc/emacs-mime.texi (time-date): Adjust to new behavior.
* etc/NEWS: Mention this.
* lisp/calendar/parse-time.el (parse-time-string):
* src/editfns.c (Fdecode_time):
Return -1 for unknown DST flag.
* test/lisp/calendar/parse-time-tests.el (parse-time-tests):
Adjust tests to match new behavior, and add a new
test for nil vs -1.
* test/lisp/calendar/icalendar-tests.el (icalendar--create-uid):
Do not intrude into or rely upon undocumented internal
implementation details of icalendar--create-uid.
Problem reported by Glenn Morris in:
https://lists.gnu.org/r/emacs-devel/2018-09/msg00660.html
* lisp/calendar/todo-mode.el (todo-add-file): Since
todo-current-todo-file must be set before calling todo-show, but
the buffer is not yet in todo-mode, which makes it buffer local,
explicitly set it buffer locally (bug#32627).
* test/lisp/calendar/todo-mode-tests.el (todo-test--add-file)
(todo-test--delete-file): New functions.
(todo-test-add-and-delete-file): New test.
* lisp/calendar/todo-mode.el (todo-edit-mode): For editing an item
instead of the whole file, the current todo-file must be set from
todo-global-current-todo-file.
* test/lisp/calendar/todo-mode-tests.el (todo-test-current-file-in-edit-mode):
New test.
* lisp/calendar/todo-mode.el (todo-edit-file): Make the warning
also suitable for Todo Archive mode, and add more space to it.
(todo-edit-quit): On quitting editing an archive file, return to
the Todo Archive mode buffer editing was invoked in.
(todo-check-format): Display a warning instead of a message when
the categories sexp isn't as expected.
(todo-mode-external-set): Remove.
(todo-edit-mode): Set buffer local values of
todo-current-todo-file and todo-categories from the todo or
archive file being edited.
(todo-categories-mode): Set buffer local values of
todo-current-todo-file and todo-categories as before but directly
instead of using superfluous todo-mode-external-set function.
* test/lisp/calendar/todo-mode-tests.el (todo-test-edit-quit): New test.
The done items separator is not reachable by todo-mode navigation
commands, but it is e.g. by C-n and C-p. Ensure that invoking
todo-mode commands with point on the separator does not result in
unexpected results, errors or file corruption (bug#32343).
* lisp/calendar/todo-mode.el (todo-insert-item--basic): Make
copying item and inserting item "here" noops when invoked on done
items separator. Consolidate error handling of these cases. Also
restrict "here" insertion to valid positions in the current
category, since this is simpler than the previous behavior of
inserting as the first item, which was moreover undocumented,
counterintuitive and superfluous.
(todo-set-item-priority, todo-move-item, todo-item-done)
(todo-item-start, todo-item-end): Make noops when invoked on done
items separator.
* test/lisp/calendar/todo-mode-tests.el: Require ert-x.
(todo-test--insert-item): Add formal parameters of
todo-insert-item--basic.
(todo-test--done-items-separator): New function.
(todo-test-done-items-separator01-bol)
(todo-test-done-items-separator01-eol)
(todo-test-done-items-separator02-bol)
(todo-test-done-items-separator02-eol)
(todo-test-done-items-separator03-bol)
(todo-test-done-items-separator03-eol)
(todo-test-done-items-separator04-bol)
(todo-test-done-items-separator04-eol)
(todo-test-done-items-separator05-bol)
(todo-test-done-items-separator05-eol)
(todo-test-done-items-separator06-bol)
(todo-test-done-items-separator06-eol)
(todo-test-done-items-separator07): New tests.
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.
* 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.
* test/lisp/calendar/todo-mode-tests.el (with-todo-test):
Declare an Edebug spec. Restore pre-test-run state of test files.
(todo-test--show, todo-test--move-item)
(todo-test--insert-item): New functions.
(todo-test-get-archive): Remove, as subsumed by
todo-test--show. Adjust all callers.
(todo-test--is-current-buffer): Rename from
todo-test-is-current-buffer and adjust uses.
(todo-test-item-highlighting): Use todo-test--show.
(todo-test-revert-buffer01, todo-test-revert-buffer02)
(todo-test-raise-lower-priority)
(todo-test-todo-mark-unmark-category, todo-test-move-item01)
(todo-test-move-item02, todo-test-move-item03)
(todo-test-move-item04, todo-test-move-item05)
(todo-test-toggle-item-header01)
(todo-test-toggle-item-header02)
(todo-test-toggle-item-header03)
(todo-test-toggle-item-header04)
(todo-test-toggle-item-header05)
(todo-test-toggle-item-header06)
(todo-test-toggle-item-header07): New tests.
* test/lisp/calendar/todo-mode-resources/todo-test-1.toda:
* test/lisp/calendar/todo-mode-resources/todo-test-1.todo:
Modify to accommodate new tests.
This avoids having to set todo-mode variables globally in the test
file and prevents any exisiting user todo-mode files from influencing
the tests.
* test/lisp/calendar/todo-mode-tests.el:
(with-todo-test): New macro.
(todo-test-todo-quit01, todo-test-todo-quit02)
(todo-test-item-highlighting): Use it.
*test/lisp/calendar/todo-mode-tests.el:
*test/lisp/calendar/todo-mode-resources/todo-test-1.toda:
*test/lisp/calendar/todo-mode-resources/todo-test-1.todo: New files.
* .gitattributes: Ignore trailing whitespace in todo-mode test
data files, since it is part of the todo-mode file format.
* lisp/emacs-lisp/ert-x.el (ert-with-function-mocked): Remove macro
in favour of ‘cl-letf’ macro which is more generic. All existing
uses are migrated accordingly. The macro has not been included in
an official release yet so it should be fine to delete it.
