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.
* doc/lispref/processes.texi (Bindat Examples): Remove, fixing
a FIXME in the manual. The long example had bitrotted to some
extent, compared to the more-up-to-date example in bindat.el
commentary, which apparently what people were referring to
anyway. The short example was confusing and not that useful
and will be obsolescent anyway if we change timestamp format.

* lisp/replace.el (occur--parse-occur-buffer): Since point is at the
beginning of the buffer, use `point'.
(occur-revert-function): Prefer `pcase-let' and `point-min'.
Check whether `region-start' or `region-end' are non-nil.

Store the region and orig line into the *Occur* header line.
Retrieve this information in `occur-revert-function'.
* lisp/replace.el (occur--parse-occur-buffer): New defun.
(occur-revert-function): Use it.
(occur-engine): Store region and original position as text properties
into the *Occur* header line.
* lisp/replace.el (occur-engine): Add sensible default values for
(occur--orig-line and nlines.
* src/gnutls.c (gnutls_cipher_get_tag_size): Make it return
zero only for versions of GnuTLS < 3.2.2, where
gnutls_cipher_get_tag_size was introduced. This fixes the
GnuTLS test suite, which assumes that any cipher whose tag
size is non-zero is AEAD-capable, and doesn't test such ciphers
if AEAD is not available, i.e. for GnuTLS < 3.5.1. (Bug#32446)
We previously used functions available only in 3.2+ for all 3.x
versions.
* src/gnutls.c [GNUTLS_VERSION_NUMBER < 0x030501]: Replace calls to
gnutls_cipher_get_tag_size with 0.
[GNUTLS_VERSION_NUMBER < 0x030200]: Alias gnutls_cipher_get_iv_size
to gnutls_cipher_get_block_size, gnutls_digest_list to
gnutls_mac_list, and gnutls_digest_get_name to gnutls_mac_get_name.
[WINDOWSNT]: Adjust DLL function definitions and declarations
accordingly.
(ad-get-advice-info): Mark it inlinable.
(ad-get-advice-info-macro): Make it an obsolete alias.
(ad-copy-advice-info, ad-is-advised, ad-get-advice-info-field)
(ad-find-advice, ad-macrofy, ad-lambdafy, ad-lambda-p, ad-advice-p)
(ad-compiled-p, ad-compiled-code, ad-get-cache-definition)
(ad-get-cache-id, ad-set-cache): Turn macros into defsubsts.
(ad-defadvice-flags): Make it into a plain list.
(ad-set-advice-info-field): Apply a bit of CSE.
(ad-read-advised-function, ad-do-advised-functions): Adjust accordingly.
(ad-pushnew-advised-function, ad-pop-advised-function): Also make them
into functions.
* lisp/play/bubbles.el (bubbles--col-offset)
(bubbles--row-offset): Doc fixes.
(bubbles--compute-offsets): Conflate the GUI and TTY code into
a single common version. Set the offsets to simple numbers,
not to lists.
(bubbles--initialize, bubbles--show-scores): Wrap offset
values in a list, so that they are interpreted as pixel
values, not as units of character width. This fixes the game
on TTY frames. (Bug#32744)
This change was motivated by the desire to remove the weird
dependency of lib-src/profile.o on src/systime.h. profile.c
included systime.h only for current_timespec, and this
inclusion required systime.h to have #ifdef emacs in multiple
places and complicated further changes I have in mind.
The current_timespec decl belongs in timespec.h anyway,
and the main effect of this change is to move it there.
* lib-src/profile.c (INLINE): Remove.
Include timespec.h, not systime.h.
* lib/gettime.c (gettime): Prefer clock_gettime to nanotime,
and don’t worry about it failing on a CLOCK_REALTIME arg.
POSIX requires it to succeed and I don’t know of any
counterexamples where the fallbacks would work.
(current_timespec): Move here from src/systime.h.
Nowadays it seems to be better to not have this function
be inline.
* lib/timespec.h: Include arg-nonnull.h.
(current_timespec): New declaration.
(gettime, settime): Declare args to be nonnull.
* lib/gettime.c, lib/timespec.h: Copy from Gnulib.
* src/systime.h: Simplify by assuming ‘emacs’ is defined,
which it always is now.
(current_timespec): Move to lib/timespec.h.
In various situations, the window displaying the certificate
information can be hidden (such as if the user accidentally presses ?,
which causes the read-multiple-choice help window to replace it).
Instead of leaving the user to make a choice blindly, add a choice to
reshow the certification information.
* lisp/net/nsm.el (nsm-query-user): Add reshow choice.
* lisp/cedet/ede/pconf.el (ede-proj-configure-synchronize): Check the
first list element of mode-line-process (Bug#32564).
Copyright-paperwork-exempt: yes
* src/atimer.c (start_atimer, debug_timer_callback):
Don’t assume support for setitimer merely because struct
itimerspec works. POSIX no longer requires support for the
obsolescent setitimer function.
* 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
This is a mess. This function was added in master in afba4ccb8b,
undocumented. It was then tweaked and documented in 9824885fab.
Much later in cc233365a9 the original untweaked and undocumented
version was backported to emacs-26. This was independently
redocumented in emacs-26 in cc8f334d2d, which conflicted with the
interface changes that had been made on master.
Inhibit modification hooks when performing message coalescing because
in that case, we aren't doing the necessary preparation for running
modification hooks (i.e., we pass PREPARE=false for the insert_1_both
and del_range_both calls). See also Bug#30823 and Bug#21824.
* src/xdisp.c (message_dolog): Let-bind inhibit-modification-hooks
to t around del_range_both calls.
* lisp/filesets.el (filesets-set-config): Use 'customize-set-variable'
so that filesets are saved by 'customize-save-customized' in
'filesets-save-config'. (Bug#20630)
Copyright-paperwork-exempt: yes
* test/src/buffer-tests.el
(overlay-modification-hooks-deleted-overlay): New test.
* src/buffer.c (report_overlay_modification): Don't bypass all
the overlay-modification hooks; instead, invoke each function
only if the buffer associated with the overlay is the current
buffer. (Bug#30823)
* lisp/thingatpt.el (thing-at-point-bounds-of-list-at-point): Revert
to pre 26.1 behavior. Return whole sexp at point if no enclosing
list.
(list-at-point): New optional arg to ignore comments and strings.
* test/lisp/thingatpt-tests.el
(thing-at-point-bounds-of-list-at-point): Fix and augment tests.
