See <https://lists.gnu.org/r/emacs-devel/2019-05/msg00062.html> and
Bug#35334.
* doc/lispref/processes.texi (Filter Functions): Go back to using
plain insert in the example filter.  Add note about updating window
point.

* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-use-jump-table): Set
to nil by default.

Don't merge to master, the bug is already fixed there.

* lisp/emacs-lisp/bytecomp.el (byte-compile-callargs-warn): Don't pass
symbols which don't have a known definition to
byte-compile--function-signature, it fails to compile code which
previously compiled successfully (for example, gnus.el until
2019-06-01 "* lisp/gnus/gnus.el: Mark autoloaded macros as such" which
autoloads some macros as if they were functions).

This avoids a build failure.

* etc/HELLO: Set 'inhibit-compacting-font-caches' non-nil
locally.  (Bug#36032)

* lisp/files.el: Add 'inhibit-compacting-font-caches' to the
list of built-in variables for which we set up
'safe-local-variable' properties.

* doc/lispref/variables.texi (File Local Variables): Document
how to define 'safe-local-variable' properties for built-in
variables.

`url-insert-file-contents` saves in buffer-file-coding-system
the coding-system used to decode the contents.  Preserve this
as the contents is moved from buffer to string to buffer, and use
it when saving the contents to file, so as to try and better preserve
the original byte sequence.

(package--buffer-string, package--cs): New functions.
(package--check-signature): Encode `string` if a coding-system
was specified in buffer-file-coding-system.
(package--download-one-archive, package-install-from-archive):
Obey and preserve the buffer-file-coding-system if specified.

Do not merge.

* lisp/emacs-lisp/bytecomp.el (byte-compile-callargs-warn): Don't
assume byte-compile-fdefinition will return non-nil.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-warn-wrong-args)
(bytecomp-warn-wrong-args-subr): New tests.

Since Emacs 26, eieio objects use a class record (with circular
references) as the type descriptor of the object record.  This causes
problems when reading back an object from a string, because the class
record is not `eq' to the canonical one (which means that read objects
don't satisfy the foo-p predicate).
* lisp/emacs-lisp/eieio.el (make-instance): As a (partial) fix, set
the record's type descriptor to a plain symbol for the type descriptor
when eieio-backward-compatibility is non-nil (the default).
* lisp/emacs-lisp/eieio-core.el (eieio--object-class): Call
eieio--class-object on the type tag when eieio-backward-compatibility
is non-nil.
(eieio-object-p): Use eieio--object-class instead of
eieio--object-class-tag.
* test/lisp/emacs-lisp/eieio-tests/eieio-test-persist.el
(eieio-test-persist-hash-and-vector)
(eieio-test-persist-interior-lists): Make into functions.
(eieio-persist-hash-and-vector-backward-compatibility)
(eieio-persist-hash-and-vector-no-backward-compatibility)
(eieio-test-persist-interior-lists-backward-compatibility)
(eieio-test-persist-interior-lists-no-backward-compatibility): New
tests which call them, eieio-backward-compatibility let-bound.

* src/gmalloc.c (_fraghead) [!HYBRID_MALLOC]:
Make it static in this case, too.  This avoids having both
‘extern struct list _fraghead[];’ and
‘static struct list _fraghead[BLOCKLOG];’, which
GCC 9 complains about.

* src/image.c (svg_load_image): Pacify librsvg 2.45.1 and later,
and add a FIXME comment about the deprecated librsvg functions.
Backport from master.

* src/dbusbind.c (xd_signature): Use simpler way to set up
the subsignature.  This also pacifies GCC 9 on Fedora 30 x86-64.
Backport from master.

* src/unexelf.c (unexec): Pacify GCC 9.

* m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Remove -Wchkp.
This suppresses a boatload of warnings of the form
“gcc: warning: switch ‘-Wchkp’ is no longer supported”.
when using GCC 9.  Do not merge to master.

* lisp/bookmark.el (bookmark-get-bookmark): Document optional
argument NOERROR. (bug#20148)

* lisp/emacs-lisp/rmc.el (read-multiple-choice): When `read-char'
signals an error "Non-character input-event", call `read-event' to
take the non-character event out of the queue.  Don't merge to master,
we just use `read-event' directly there, rather than this solution
which relies a particular error message.
