* lisp/progmodes/compile.el (compilation--downcase-mode-name): New
function.
(compilation-start, kill-compilation): Use it instead of calling
'downcase' on 'mode-name'. (Bug#68795)

server's network ID in query buffers created before MOTD's end. Do
this to avoid a type error in the process filter when renaming
buffers.

New file.
* test/lisp/erc/resources/erc-tests-common.el
(erc-tests-common-make-server-buf): Use NAME parameter for creating
ID.
* etc/ERC-NEWS: Mention renaming of `erc-munge-invisible-property'.

correct function from `erc-mode-hook'.
(erc-stamp--recover-on-reconnect): Revise doc string.
(erc-munge-invisibility-spec, erc-stamp--manage-local-options-state):
Mark former name as obsolete and rename to latter. Don't use helper
macro meant only for local modules. This bug originated from c68dc778
"Manage some text props for ERC insertion-hook members", which stemmed
from bug#60936.
(erc-stamp--setup, erc-hide-timestamps, erc-show-timestamps)
(erc-toggle-timestamps): Use new name for
`erc-munge-invisibility-spec'.

* lisp/erc/erc-goodies.el (erc-scrolltobottom-mode)
(erc-scrolltobottom-enable): Use `setq' instead of `setopt' because
the latter isn't defined in Emacs 27 and 28. This fix is unrelated to
the main thrust of this commit.
* lisp/erc/erc.el (erc-modules): Make good on decades old language in
info node "(erc) Modules" by ensuring `customize-option' can find this
option before its containing library is loaded. Like
`gnus-select-method', this option serves as an entry point for
configuring the application and is presented that way in tutorials and
library front matter. Moreover, it can't be reasonably autoloaded in
the traditional way because of its many dependencies and large textual
footprint.
(erc-display-message): Revise doc string.
* lisp/progmodes/cperl-mode.el (cperl-info-on-command): Simplify,
to let `pop-to-buffer` decide whether to create a new frame or not,
so it can be controlled by `display-buffer-alist`.
We used to print dynamic docstrings "manually" for two reasons:
- References should look like `(#$ . POS)` but `prin1` was unable
to print just `#$` for an sexp.
- `make-docfile` needed to find those docstrings and the object
to which they belonged.
The second point is moot now that we don't use `make-docfile` on
`.elc` files. So this patch lifts the first restriction,
using `print-number-table`.
The rest of the patch then simplifies and regularises the
bytecompiler's generation of dynamic docstrings, which can
now also easily be done for "inner" defvars and other places.
* src/print.c (print_preprocess, print_object): Handle strings in
`print-number-table`.

Delete functions.
(byte-compile-file-form-autoload, byte-compile-file-form-defalias)

(byte-compile-defvar): Add `toplevel` arg. Use `byte-compile--docstring`.

* lisp/help-fns.el (describe-face): Simplify accordingly.
Monitors are wider now than when these defaults were first set, and it
is useful to take better advantage of that, to fit text on fewer lines.
Yet, it has repeatedly been shown that overly long lines reduce
readability:
"A reasonable guideline would be 55 to 75 characters per line."[1]
We also don't want to disfavor narrow displays, like mobile phones; a
more promising direction here might be to automatically word wrap
docstrings and make their maximum width customizable. That might
require a new docstring format, however.
Bumping it by 7 characters, from 65 to 72, seems a reasonable compromise
for now. Consideration was given to increasing it to 70 or 75, but 72
happens to be a commonly recommended maximum line width elsewhere (see
Fortran 66, Python docstrings, commit message recommendations, etc.),
and we might as well do the same.

prefixes, and subtracted from it->current_x when computing tab
widths.

computing the base position of a tab character, do not subtract
the continuation line width if a line prefix is the current
iterator method. Subtract the wrap_prefix_width otherwise, in
order that the width of the tab is computed free of influence
from the wrap prefix.

* lisp/visual-wrap.el (visual-wrap-prefix-mode): Document this
new global minor mode.

Only use fast-path optimisations for calls and dynamic variable
reference and setting where the symbol is plain, which is much faster.
The obsolete lazy-loaded bytecode feature, enabled by
`byte-compile-dynamic`, slows down Lisp execution even when not in use
because every call to a bytecode function has to check that function
for laziness.
This change forces up-front loading of all lazy bytecode so that we
can remove all those checks. (Dynamically loaded doc strings are not
affected.)
There is no point in generating lazy bytecode any more so we stop
doing that; this simplifies the compiler. `byte-compile-dynamic` now
has no effect.
This is a fully compatible change; the few remaining users of
`byte-compile-dynamic` should not notice any difference.
* src/lread.c (bytecode_from_rev_list): Force eager loading of
lazy bytecode.
* src/bytecode.c (exec_byte_code): Remove lazy bytecode checks.
* src/eval.c (fetch_and_exec_byte_code, Ffetch_bytecode): Remove.
(funcall_lambda): Call exec_byte_code directly, avoiding checks.

(byte-compile-file-form-defmumble):
Remove effects of byte-compile-dynamic.
* doc/lispref/compile.texi (Dynamic Loading): Remove node now that
the entire `byte-compile-dynamic` facility has been rendered inert.
* etc/NEWS: Announce changes.
Hash tables using different user-defined tests defined identically
sometimes ended up using the wrong test (bug#68668).
* src/fns.c (get_hash_table_user_test): Take test name into account
when matching the test object.
* test/src/fns-tests.el (fns--define-hash-table-test): New.
This fixes a hang that would frequently rear its ugly head while
displaying messages in the `telega.el' instant messenger client,
which inserts images approaching the width of the window with
line and wrap prefixes.
* src/xdisp.c (move_it_in_display_line_to): If a line or wrap
prefix is set in place, do not generate continuation lines until
a minimum of one glyph has been produced outside that prefix.
(move_it_to): Remove the previous workaround that could not
recover from errors caused by display strings.
(display_line): Synchronize with move_it_in_display_line_to;
remove old workaround that only provided for oversized wrap
prefixes comprising `space' display objects.
Take this code as an example:
1 class Foo
2 {
3 /**
4 * Block comment
5 */
6 function foo($c) {
7 }
8 }
Suppose the block comment is covered by a local parser. When we
indent line 3, treesit--indent-1 will try to get the local parser at
the BOL, and it'll get the local parser. But it shouldn't use the
local parser to indent this line, it should use the host parser of
that local parser instead.
So now, if treesit--indent-1 gets a local parser, but the local
parser's root node's start coincides with BOL, treesit--indent-1 will
use the host parser to indent this line.
We also need to make treesit--update-ranges-local to save the host
parser along with the local parser, and make
treesit-local-parsers-at/on extract and return the host parser.
I also switch the two cases in the cond form in treesit--indent-1:
(null (treesit-parser-list)) and (car local-parsers), (car
local-parsers) now takes precedence.
* lisp/treesit.el (treesit-local-parsers-at):
(treesit-local-parsers-on): Add WITH-HOST parameter.
(treesit--update-ranges-local): Save the host parser to the local
overlay.
(treesit--indent-1): If the root node of the local parser is at BOL,
use the host parser instead.
* lisp/emacs-lisp/bytecomp.el (byte-compile--reify-function):
Use `macroexp-parse-body` and only handle closures.
(byte-compile): Clarify the control and data flow a bit.
* lisp/vc/log-edit.el (log-edit--insert-filled-defuns): Don't
open a new line for long defuns at column 0.
* test/lisp/vc/log-edit-tests.el
(log-edit-fill-entry-space-substitution): Adjust expected
results to match change.
(log-edit-fill-entry-initial-wrapping): New test.

break points.

(log-edit-fill-entry-space-substitution): New test.
