* doc/lispref/display.texi (Low-Level Font)
<font-xlfd-name>: Document new argument `long-xlfds'.
* etc/NEWS: Mention removal of XLFD length restrictions.
* src/font.c (font_build_object): Dynamically allocate XLFD,
permitting them to surpass 255 characters in length.
(font_parse_xlfd_1): Cease rejecting XLFDs more than 255
characters in length.
(font_dynamic_unparse_xlfd): New function. Like
font_unparse_xlfd, but allocate the XLFD dynamically.
(font_delete_unmatched): Dynamically allocate XLFD if necessary.
(Ffont_xlfd_name): New arg LONG_XLFDs. If t, return a
dynamically allocated XLFD. All callers changed.
* src/font.h: Update prototypes.

establishing fontset name.
To improve consistency. We already have treesit-node-at and
treesit-node-on.

Signal error if the symbol to make obsolete is nil or t. (Bug#62248)
(byte-run--constant-obsolete-warning): New function.
* test/lisp/emacs-lisp/byte-run-tests.el: New file.
* lisp/minibuffer.el (minibuffer--regexp-propertize):
The original regexp had 83 backslashes in 147 characters which may be
some kind of record. This transformation cuts it down to 6, and the
generated regexp string is about 14 % shorter.
Hoist the `eval-when-compile` to encompass the entire list, since
backquote forms aren't automatically evaluated at compile time.
This results in a single constant list in the generated code, and
much less actual code.
* admin/notes/tree-sitter/build-module/batch.sh (languages):
Add Java.
* lisp/progmodes/java-ts-mode.el (java-ts-mode): Pass a list
to 'treesit-thing-settings'.
This mode is for editing regexps in minibuffer, it highlights
parens via `show-paren-mode' and `blink-matching-paren' in a
user-friendly way, avoids reporting false paren mismatches,
and makes sexp navigation more intuitive.

Substring completion would previously not complete the longest common
substring if that substring was a prefix of all the completion
alternatives. Now it does. An explanation of this bug
Substring completion is implemented by passing the `prefix' symbol as
part of the pattern passed to completion-pcm--merge-completions. This
symbol is supposed to cause completion-pcm--merge-completions to
"grow" a completion of a common substring only from the "right" of the
symbol (a common suffix), not from the "left" of the symbol (a common
prefix). Yes, this is the opposite of what the name `prefix' would
imply.
When processing a symbolic element of the pattern,
completion-pcm--merge-completions first finds the common prefix of all
the completions in that part of the pattern (using try-completion).
Then for `prefix' and other elements which want to complete a common
suffix, the common prefix is removed from each element and then the
common suffix is calculated with completion--common-suffix.
If the common prefix covers the entirety of all the alternatives
(i.e. when "unique" is true in the code), it's also a common suffix.
In that case, the common suffix calculation (if it runs) is basically
a no-op which will produce an empty string, since we removed the
common prefix before running it.
Before this change, `prefix' elements would unconditionally discard
the common prefix, which produced the wrong result in the case that
common prefix == common suffix. For example:
(completion-pcm--merge-completions '("ab" "ab") '(prefix "b"))
-> ("b")
Now we detect this situation and include the common prefix in this
case for `prefix' elements. Then we get:
(completion-pcm--merge-completions '("ab" "ab") '(prefix "b"))
-> ("b" "a")
which is correct.
* lisp/minibuffer.el (completion-pcm--merge-completions): Don't ignore
a common suffix in a `prefix' pattern element when it's also a common
prefix.
* test/lisp/minibuffer-tests.el (completion-substring-test-5): Add a
test.
* lisp/treesit.el (treesit--read-major-mode): Helper function to
provide completion for most major modes.
(treesit-check-indent): Use the new interactive spec and improve the
docstring. (Bug#60001)
When scrolling heavily (perhaps holding down C-n), the function
'flymake-mode-line-counter' showed very prominently in the memory and
CPU profiles.
Using a cache here was trivial, if not particularly pretty. The
function all but disappears from the profiles afterwards.
* lisp/progmodes/flymake.el (flymake--mode-line-counter-cache):
New variable.
(flymake--publish-diagnostics): Flush cache aggressively.
(flymake-mode-line-error-counter): Adjust.
(flymake--mode-line-counter-1): New helper from earlier
flymake--mode-line-counter.
(flymake--mode-line-counter): Use cache.
* src/androidfns.c (Fx_display_backing_store): Return
`when-mapped' in place of `always', since the former better
reflects Android port behavior.
(syms_of_androidfns) <always>: Delete defsym.
<when-mapped>: New defsym.
* src/term.c (Fsuspend_tty, Fresume_tty): Properly signal errors
on Android rather than quietly disregarding calls.
