* lisp/emacs-lisp/eieio-base.el (eieio-persistent-slot-type-is-class-p):
An `or' form can specify multiple potential classes (or null) as
valid types for a slot, but previously only the final element of the
`or' was actually checked. Now returns all valid classes in the `or'
form.
(eieio-persistent-validate/fix-slot-value): Check if proposed value
matches any of the valid classes.
* test/lisp/emacs-lisp/eieio-tests/eieio-test-persist.el
(eieio-test-multiple-class-slot): Test this behavior.
* 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)
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'.

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.
* lisp/emacs-lisp/autoload.el (autoload--save-buffer):
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
Use make-temp-file, not make-temp-name, to avoid an unlikely race
that could lose data. Remove the deletion hook as quickly as
possible after the file is renamed; though a race still remains
here, it is smaller than before.
* lisp/ruler-mode.el (ruler-mode-ruler, ruler-mode-window-col):
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-init-header)
(tabulated-list-print-entry): Account for the width taken by
line-number display. (Bug#27895)
(symbol-file): Make it find symbol property definitions.
* lisp/emacs-lisp/pcase.el (pcase-defmacro):
* lisp/emacs-lisp/ert.el (ert-set-test): Use it instead of `put'.
(ert-describe-test): Adjust call to symbol-file accordingly.
* lisp/emacs-lisp/cl-generic.el (cl-generic-p): New function.
(cl--generic-method-files): New function, moved from subr.el.
* lisp/emacs-lisp/edebug.el (edebug-instrument-function): Use them.
* test/lisp/emacs-lisp/cl-generic-tests.el:
* test/lisp/subr-tests.el: Move and adjust method-files tests accordingly.
* lisp/emacs-lisp/ert.el
(ert-results-pop-to-backtrace-for-test-at-point):
Set multibyte true, not false. This copies a
debugger-setup-buffer change from 2009-08-30, and stops the
"Backtrace for" header line containing ^X and ^Y.
If TESTFN is non-nil, then it is the predicate to lookup
the alist. Otherwise, use 'eq' (Bug#27584).
* lisp/subr.el (alist-get): Add optional arg FULL.
* lisp/emacs-lisp/map.el (map-elt, map-put): Add optional arg TESTFN.
* lisp/emacs-lisp/gv.el (alist-get): Update expander.
* doc/lispref/lists.texi (Association Lists): Update manual.
* etc/NEWS: Announce the changes.
* test/lisp/emacs-lisp/map-tests.el (test-map-put-testfn-alist)
(test-map-elt-testfn): New tests.
* lisp/emacs-lisp/bytecomp.el (byte-compile--function-signature): New fun.
Dig into advice wrappers to find the "real" signature.
(byte-compile-callargs-warn, byte-compile-arglist-warn): Use it.
(byte-compile-arglist-signature): Don't bother with "new-style" arglists,
since bytecode functions are now handled in byte-compile--function-signature.
* lisp/files.el (create-file-buffer, insert-directory):
Remove workaround introduced for (bug#14860).
* lisp/help-fns.el (help-fns--analyse-function): `nadvice` is preloaded.
* lisp/help.el (help-function-arglist):
Dig into advice wrappers to find the "real" signature.
Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a)
would dump core, since the C code would recurse indefinitely through
the infinite structure. This patch adds an argument to the function,
and renames it to lread--substitute-object-in-subtree as the function
is not general-purpose and should not be relied on by outside code.
See Bug#23660.
* src/intervals.c (traverse_intervals_noorder): ARG is now void *,
not Lisp_Object, so that callers need not cons unnecessarily.
All callers changed. Also, remove related #if-0 code that was
“temporary” in the early 1990s and has not been compilable for
some time.
* src/lread.c (struct subst): New type, for substitution closure data.
(seen_list): Remove this static var, as this info is now part of
struct subst. All uses removed.
(Flread__substitute_object_in_subtree): Rename from
Fsubstitute_object_in_subtree, and give it a 3rd arg so that it
doesn’t dump core when called from the top level with an
already-cyclic structure. All callers changed.
(SUBSTITUTE): Remove. All callers expanded and then simplified.
(substitute_object_recurse): Take a single argument SUBST rather
than a pair OBJECT and PLACEHOLDER, so that its address can be
passed around as part of a closure; this avoids the need for an
AUTO_CONS call. All callers changed. If the COMPLETED component
is t, treat every subobject as potentially circular.
(substitute_in_interval): Take a struct subst * rather than a
Lisp_Object, for the closure data. All callers changed.
* test/src/lread-tests.el (lread-lread--substitute-object-in-subtree):
New test, to check that the core dump does not reoccur.
* lisp/emacs-lisp/lisp-mode.el (lisp-comment-indent): Only check for
open paren if we're looking at multiple comment characters.
* test/lisp/emacs-lisp/lisp-mode-tests.el (lisp-comment-indent-1)
(lisp-comment-indent-2): New tests.
* lisp/emacs-lisp/lisp-mode.el (lisp-comment-indent): If current
line's code ends in open paren, set comment indentation exactly to
column following it.
(lisp-mode-variables): Set `comment-indent-function' to
`lisp-comment-indent'.
* lisp/emacs-lisp/debug.el (debugger-insert-backtrace):
* lisp/help-fns.el (describe-variable): No need to let-bind
`cl-print-compiled-button' to t anymore.
(cl--random-state, cl--random-time): Move from cl-lib.el.
(cl-random): Use struct accessors.
(cl-random-state-p): Remove, provided by the defstruct.
(cl-make-random-state): Rewrite to struct constructor.
* lisp/emacs-lisp/debug.el (debugger-print-function): New defcustom,
defaulting to `cl-print'.
(debugger-insert-backtrace, debugger-setup-buffer): Use it instead of
`prin1'.
* etc/NEWS: Announce it.
* lisp/emacs-lisp/cl-print.el (cl-print-object): Don't print arglist
part of docstring.
* test/lisp/emacs-lisp/cl-print-tests.el (cl-print-tests-1): Update
test accordingly.
Change ert to use the new `backtrace-frames' function instead of
collecting frames one by one with `backtrace-frame'. Additionally,
collect frames starting from `signal' instead the somewhat arbitrary
"6 from the bottom". Skipping 6 frames would skip the expression that
actually caused the signal that triggered the debugger. Possibly 6
was chosen because in the case of a failed test, the triggering frame
is an `ert-fail' call, which is not so interesting. But in case of a
test throwing an error, this drops the `error' call which is too much.
* lisp/emacs-lisp/debug.el (debugger-make-xrefs): Remove.
* lisp/emacs-lisp/ert.el (ert--make-xrefs-region): Bring in relevant
code from `debugger-make-xrefs'.
(ert--print-backtrace): Add DO-XREFS parameter, delegate to
`debugger-insert-backtrace'.
(ert--run-test-debugger): Record the backtrace frames starting from
the instigating `signal' call.
(ert-run-tests-batch): Pass nil for `ert--print-backtrace's new
DO-XREFS parameter.
(ert-results-pop-to-backtrace-for-test-at-point): Pass t as DO-XREFS
to `ert--print-backtrace' and remove call to `debugger-make-xrefs'.
* test/lisp/emacs-lisp/ert-tests.el (ert-test-record-backtrace): Check
the backtrace list instead of comparing its string representation.
Expect `signal' to be the first frame.
* lisp/emacs-lisp/debug.el (debugger-insert-backtrace): New function,
prints the given backtrace frames.
(debugger-setup-buffer): Use it instead of editing the backtrace
buffer text.
* lisp/emacs-lisp/cl-print.el: Autoload `disassemble-1'.
(cl-print-compiled-button): New variable.
(help-byte-code): New button type, calls `disassemble' in its action.
(cl-print-object): Use it if `cl-print-compiled-button' is
non-nil.
* lisp/emacs-lisp/cl-macs.el (cl--sm-macroexpand): Remove.
(cl-symbol-macrolet): Instead of adding each binding directly into the
main environment with a special key format, put all symbol macro
bindings into a single entry in the main environment under
`:cl-symbol-macros'.
(cl--sm-macroexpand): Look up symbol bindings in the
`:cl-symbol-macros' entry of the environment.
A field number explicitly specifies the argument to be formatted.
This is especially important for potential localization work, since
grammars of various languages dictate different word orders.
* src/editfns.c (Fformat): Update documentation.
(styled_format): Implement field numbers.
* doc/lispref/strings.texi (Formatting Strings): Document field numbers.
* lisp/emacs-lisp/bytecomp.el (byte-compile-format-warn): Adapt.
* test/src/editfns-tests.el (format-with-field): New unit test.
