Problem for ‘read’ reported by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2019-08/msg00316.html
* src/fns.c (Frequire): Protect against circular current-load-list.
* src/lread.c (Fget_load_suffixes):
Protect against circular load-suffixes or load-file-rep-suffixes.
(Fload): Protect against circular loads-in-progress.
(openp): Protect against circular PATH and SUFFIXES.
(build_load_history): Protect against circular load-history or
current-load-list.
(readevalloop_eager_expand_eval): Protect against circular SUBFORMS.
(read1): Protect against circular data.
* test/src/lread-tests.el (lread-circular-hash): New test.
* lisp/progmodes/hideif.el (hide-ifdef-mode-prefix-key): Make into
a defcustom since it seems like this is something that should be
user-customisable (bug#8922).
* doc/misc/info.texi (Help-Q): Info now uses `quit-window'.
* lisp/info.el (info-standalone): Adjust doc string.
(Info-exit): Made into obsolete alias.
(Info-mode-map): Bind "q" to `quit-window'.
(Info-mode-menu): Adjust.
(info-tool-bar-map): Ditto.
(Info-mode): Adjust doc string.
(Info-mode): If Info is standalone, kill Emacs on "q".
* lisp/window.el (quit-restore-window): Don't run quit-window-hook
here...
(quit-window): ... but here instead. Callers that call the former
programmatically can decide themselves whether to call the hook.
(quit-window-hook): Fix doc string.
This uses ‘const’ to be better at catching bugs that
mistakenly attempt to modify a bignum value.
Lisp bignums are supposed to be immutable.
* src/alloc.c (make_pure_bignum):
* src/fns.c (sxhash_bignum):
Accept Lisp_Object instead of struct Lisp_Bignum *, as that’s
simpler now. Caller changed.
* src/bignum.h (bignum_val, xbignum_val): New inline functions.
Prefer them to &i->value and XBIGNUM (i)->value, since they
apply ‘const’ to the result.
* src/timefns.c (lisp_to_timespec): Use mpz_t const *
to point to a bignum value.
* doc/misc/emacs-mime.texi (time-date):
Adjust example to match new behavior.
* etc/NEWS: Mention this.
* lisp/calendar/time-date.el (decoded-time-add)
(decoded-time--alter-second):
Don’t lose underestimate precision of seconds component.
* src/bignum.c (mpz): Grow by 1.
* src/timefns.c (trillion_factor): New function.
(timeform_sub_ps_p): Remove.
(time_arith): Avoid unnecessarily-large hz, by reducing the hz
to a value no worse than the worse hz of the two arguments.
The result is always exact unless an error is signaled.
* test/src/timefns-tests.el (timefns-tests--decode-time):
New function.
(format-time-string-with-zone): Test (decode-time LOOK ZONE t)
resolution as well as its numeric value.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode): Accept
a BODY parameter.
* doc/lispref/modes.texi (Defining Minor Modes): Document new
parameter.
* etc/NEWS: Announce it.
* lisp/simple.el (read--expression): Move eldoc-mode setup to...
* lisp/emacs-lisp/eldoc.el (eldoc--eval-expression-setup): ... here,
new function.
(global-eldoc-mode): Add or remove it to
eval-expression-minibuffer-setup-hook when enabling or disabling
global-eldoc-mode. This enables eldoc in the minibuffer (solving
Bug#27202), only when global-eldoc-mode is enabled.
Also, improve the doc to match current behavior.
* doc/lispref/os.texi (Time Conversion): Document that
time-convert signals an error for infinite or NaN args,
and that (time-convert TIME t) is exact otherwise.
Mention float-time as an alternative to time-convert.
(Time Calculations): Document that time-add and time-subtract
are exact and do not decrease HZ below the minimum of their args.
* src/timefns.c (decode_float_time): Don’t signal an error for
floating-point arguments whose base-FLT_RADIX exponent is not less
than DBL_MANT_DIG. Instead, convert them to (TICKS . 1) values.
Use two (instead of three) integer exponent comparisons in the
typical case.
* test/src/timefns-tests.el (time-arith-tests):
Add more floating-point tests, including some tests
that the old code fails.
* test/lisp/autorevert-tests.el ()
(auto-revert-test02-auto-revert-deleted-file):
* test/lisp/filenotify-tests.el (file-notify-test04-autorevert):
Check `file-notify-valid-p', not that the descriptor is nil.
* lisp/progmodes/elisp-mode.el (elisp--fnsym-in-current-sexp): Since
forward-sexp assumes point is not in a string or comment, avoid
calling it and then checking if point is inside a string, since that
sometimes will fail with awkward results. (Bug#35567)
* lisp/international/mule-diag.el
(describe-current-coding-system): Also output the contents of
`auto-coding-alist', which take precedence over
`file-coding-system-alist' (bug#9575).
* doc/lispref/windows.texi (Quitting Windows): Mention in.
* lisp/window.el (quit-restore-window): Run the new
`quit-window-hook' before doing anything else (bug#9867).
(quit-window): Note that the hook will be run in the doc string.
* lisp/window.el (quit-window-hook): New variable.
* lisp/org/org-table.el (org-table-message-once-per-second):
Fix bug when clock difference goes past a 65536-second boundary.
Don’t assume particular format for current-time result.
* src/timefns.c (time_arith): Check the first arg for
validity even if the second arg is not finite.
* test/src/timefns-tests.el (time-arith-tests): Test this.
* doc/lispref/processes.texi (Asynchronous Processes): Note that input
may read when sending data as well.
(Output from Processes): Note that functions which send data may also
trigger reading from processes.
(Input to Processes, Filter Functions): Note that filter functions may
be called recursively.
Ensure that non-regexp strings used with `looking-at' are quoted.
* lisp/replace.el (perform-replace): Quote regexp (Bug#37073).
* test/lisp/replace-tests.el (replace-tests-perform-replace-regexp-flag):
New variable.
(replace-tests-with-undo): Use it.
(query-replace-undo-bug37073): Add tests.
Use lexical-binding.
(erc-add-timestamp): Store the timestamp in a closure placed in
cursor-sensor-functions rather than stashing it in an ad-hoc
`timestamp` property.
(erc-echo-timestamp): Simplify accordingly.
* doc/lispref/frames.texi (Frame Size): Document it.
* src/frame.c (Fset_frame_height):
(Fset_frame_width): Make into commands that use the numeric prefix
to set height/width (bug#9970).
* lisp/man.el (Man-bgproc-filter): Make sure not to chop man sections
by narrowing.
(Man-highlight-references0): Revert previous fix, as it's no longer
needed.
* test/lisp/man-tests.el (man-tests-filter-strings): New function.
(man-bgproc-filter-buttonize-includes): New test.
* src/bignum.h (bignum_integer): Now returns pointer-to-const,
to catch trivial mistakes where the caller might try to modify
a Lisp bignum. Lisp bignums are supposed to be immutable.
All callers changed.
* admin/unidata/NormalizationTest.txt:
* admin/unidata/UnicodeData.txt: Add U+32FF SQUARE ERA NAME REIWA.
Do not merge to master.
* test/lisp/international/ucs-normalize-tests.el
(ucs-normalize-tests--failing-lines-part1)
(ucs-normalize-tests--failing-lines-part2): Update. Do not
merge to master.
* etc/NEWS: Mention the change.
* lisp/org/org-timer.el (org-timer-show-remaining-time):
Don’t assume the remaining time is less than one hour.
Simplify. The simplification removes the need for a
decode-time, and fixes a typo I introduced recently.
* lisp/help-fns.el (help-fns--disabled): New function (bug#10853).
(help-fns-describe-function-functions): Add it to the list of
function help functions.
This adds FIXMEs to areas where Lisp code should support
subsecond information in broken-down timestamps.
It also fixes some unnecessary truncation of timestamps, and
ports the code to a hypothetical future Emacs version where
(decode-time) returns subsecond timestamps by default.
* lisp/calc/calc-forms.el (calc-time, math-iso-dt-to-date)
(calcFunc-now):
* lisp/calendar/icalendar.el (icalendar--add-decoded-times):
* lisp/calendar/iso8601.el (iso8601-parse-interval):
Truncate seconds to an integer, and add a FIXME about
subseconds support.
* lisp/calendar/icalendar.el (icalendar--decode-isodatetime)
(icalendar--decode-isoduration):
Add a FIXME about subseconds support.
* lisp/gnus/gnus-delay.el (gnus-delay-article):
Don’t truncate seconds to an integer, as there’s no need
to do that here.
* lisp/gnus/gnus-util.el (gnus-seconds-today)
(gnus-seconds-month, gnus-seconds-year):
* lisp/gnus/message.el (message-make-expires-date):
* lisp/org/org-timer.el (org-timer-show-remaining-time):
* lisp/vc/ediff-mult.el (ediff-format-date):
Truncate seconds to an integer, as that’s what’s wanted here.
* lisp/midnight.el (midnight-next):
Ceiling seconds to an integer, as that’s what wanted here.
