* lisp/window.el (window--quit-restore-select-window):
Add optional arg 'frame'. Don't switch to another frame
if window is not on the selected frame (bug#71386).
(quit-restore-window): Provide the 'frame' arg
to 'window--quit-restore-select-window' calls.
Patch by martin rudalics <rudalics@gmx.at>.
* test/lisp/tab-bar-tests.el (tab-bar-tests-quit-restore-window):
No need to reselect the frame after 'quit-window'.
* lisp/treesit.el (treesit-parsers-at): Add treesit-primary-parser
only when it's non-nil. When the result list is still empty,
add the first parser from 'treesit-parser-list'.
https://lists.gnu.org/archive/html/emacs-devel/2025-04/msg00627.html
* test/src/treesit-tests.el (treesit-node-supplemental)
(treesit-node-at, treesit-node-check)
(treesit-search-subtree-forward-1)
(treesit-search-subtree-backward-1): Wrap test body in 'with-temp-buffer'.
* lisp/erc/erc-backend.el (erc-server--reconnect-opened)
(erc--server-reconnect-opened): Rename former to latter. Restore
original buffer-local value of session connector for Emacs 29 and below.
(erc--server-reconnect-timeout-check)
(erc--server-reconnect-timeout-scale-function): Change from buffer-local
to normal variables, which they should have been originally.
(erc--recon-probe-reschedule): Ensure `erc-server-reconnect-timeout' is
always non-nil to avoid seeing format specifier in admin message. Use
current buffer when `proc' argument is nil. Perform cleanup when `proc'
and `erc-server-process' differ.
(erc-server-delayed-check-reconnect-reuse-process-p): New variable.
(erc--recon-probe-sentinel): Run `erc--server-reconnect-opened'
immediately because sending a speculative PING doesn't work on all
servers and proxies, most crucially on ZNC, which replies with an error
only after an extended timeout.
(erc--recon-probe-filter): Remove unused function.
(erc--recon-probe-check) Rework to not use fixed periodic timer, change
second parameter to a Lisp time object.
(erc-server-delayed-check-reconnect): Use realistic name when reusing
process so that the session's process isn't "*erc-connectivity-check*".
Set filter to `ignore'. Always run `erc--recon-probe-sentinel' when
status is `open' or something other than `connect', but don't bother
spawning a `erc--recon-probe-check' task as well because any problems
creating the process should already be known. Handle quits during
connect functions that perform blocking I/O, such as
`socks-open-network-stream'.
(erc-schedule-reconnect): Don't bother setting filter to nil.
* test/lisp/erc/erc-scenarios-base-auto-recon.el
(erc-scenarios-base-auto-recon-unavailable)
(erc-scenarios-base-auto-recon-check/no-reuse): Rename former to latter.

rewrite not to expect a PING.
* test/lisp/erc/resources/erc-d/erc-d.el (erc-d--forget-process): New
function.
(erc-d--process-sentinel): Stop serving when all dialogs have been
exhausted. (Bug#62044)
* test/lisp/tab-bar-tests.el (tab-bar-tests-quit-restore-window):
Skip test on MS-Windows in batch mode, since terminal frames
cannot be created in that case.
* test/lisp/emacs-lisp/find-func-tests.el
(find-func-tests--locate-macro-generated-symbols): bind
'trusted-content' to names of files in which we want to
expand macros during this test.
* lisp/url/url-parse.el (url-generic-parse-url): Remove prefix /
when a file URI's filename starts with a single letter followed
by a colon and a slash or backslash.
(url-recreate-url): Mirror the change applied when parsing, so
the URL is recreated properly on MS-Windows.
* test/lisp/url/url-parse-tests.el
(url-generic-parse-url/ms-windows-file-uri-hanlding): New test.
(Bug#76982)
Before this change, a chunk containing only a part
of a multibyte character would be discarded and
displayed undecoded on the terminal.
* lisp/term.el (term-emulate-terminal): Fix handling chunks
with part of a multibyte character. (Bug#77410)
* test/lisp/term-tests.el (term-decode-partial)
(term-undecodable-input): Fix and enhance tests.

An explicitly typed * has different semantics from automatically
inserted PCM wildcards, so it should be preserved on try-completion. We
already do this in some cases, but now we do it more.
This is especially significant for filename completion: removing an
explicit * can take us from
~/src/emacs/trunk/*/minibuf
to
~/src/emacs/trunk//minibuf
The explicit double slash is interpreted by the file name completion
table to mean "start completing from the root directory", so deleting
the * here substantially changes semantics.
* lisp/minibuffer.el (completion-pcm--merge-completions): Don't drop
important wildcards. (bug#74420)
* test/lisp/minibuffer-tests.el (completion-pcm-test-7): Add tests.

(eieio-test-method-order-list-4): Make sure backward compatibility is
active when testing the obsolete name arg.

* lisp/textmodes/reftex.el (reftex--get-buffer-identifier)
(reftex--get-directory, reftex--abbreviate-name)

(reftex-get-file-buffer-force): Handle buffer objects and
special 'buffer:' strings.
* lisp/textmodes/reftex-global.el (reftex-create-tags-file): Add
error handling for non-file buffers. Leave TAGS unsupported in
non-file buffers.
(reftex-find-duplicate-labels)
(reftex-isearch-switch-to-next-file): Use new helper functions
that handle both files and buffer objects.

non-file buffers. Leave phrases unsupported in non-file
buffers.

(reftex-parse-from-file): Add support for non-file buffers.
(reftex-all-document-files, reftex-where-am-I)
(reftex-notice-new): Use new helper functions.
* lisp/textmodes/reftex-ref.el (reftex-label-info-update):

(reftex-save-all-document-buffers, reftex-ensure-write-access):
Ignore non-file buffers.
* lisp/textmodes/reftex-parse.el (reftex-all-document-files):
For non-file objects, do not apply relative path transformation.
* test/lisp/textmodes/reftex-tests.el
(reftex-all-used-citation-keys-buffer)
(reftex-renumber-simple-labels-buffer): New tests for operations
on non-file buffers.
RefTeX historically assumed that the buffers it operates on
visit files. To handle non-file buffers:
Modify reftex-TeX-master-file so that it returns the buffer
object itself (as suggested by Stefan Monnier). Modify each
caller to handle buffer objects, aided by some helper functions
added to reftex.el. Replace 'string=' by 'equal' in places.
Use buffer-base-buffer, where appropriate, to handle indirect
buffers (file and non-file).
TAGS files and phrases buffers remain unsupported for non-file
buffers.
Problem: In Ruby we can define a nested module/class the safe
way (in the sense, if the parent module does not exist, it will
define it:
module M
module N
end
end
If M already exists, we can also write:
module M::N; end
With the later notation, the tag generated by etags will be M::N.
When browsing the code, using xref-find-definitions when the point
is on N, will not be able to find the definition of N because the
implicit tag name is M::N.
This is the same problem with nested classes or even some rare
allowed definitions like explicitely defining a module/class from
the global namespace:
class ::A; end
Solution: We need to give an explicit tag name. To achieve this,
on module/class definition we truncate the name to the last found
column.
* lib-src/etags.c (Ruby_functions): Support "::" in module
definitions.

Swap the role of `replace-region-contents` and `replace-buffer-contents`,
so `replace-region-contents` is the main function, implemented in C,
and `replace-buffer-contents` is a mere wrapper (marked as obsolete).
Also remove the need to rely on narrowing and on describing the
new text as a function.
Finally, allow MAX-SECS==0 to require a cheap replacement, and
add an INHERIT argument.
* src/editfns.c: Include `coding.h`.
(Freplace_region_contents): Rename from `Freplace_buffer_contents`.
Change calling convention to that of `replace-region-contents`.
Add more options for the SOURCE argument. Add INHERIT argument.
Skip the costly algorithm if MAX-SECS is 0.
* src/insdel.c (replace_range): Allow NEW to be a buffer.
* lisp/subr.el (replace-buffer-contents): New implementation.
* lisp/emacs-lisp/subr-x.el (replace-region-contents): Delete.
* doc/lispref/text.texi (Replacing): Document new API for
`replace-region-contents`. Remove documentation of
`replace-buffer-contents`.
* test/src/editfns-tests.el (replace-buffer-contents-1)
(replace-buffer-contents-2, replace-buffer-contents-bug31837):
Use `replace-region-contents`.

(editfns-tests--replace-region): Use `replace-region-contents`.
Adds tests for new types of SOURCE args.
This function tests whether a given key is present in a hash table.
Emacs Lisp has long lacked a standard way to do this, leading users to
write one of:
(not (eq (gethash key table 'missing) 'missing))
or
(gethash key table)
This idiom is error-prone (when 'missing' or 'nil' are valid values),
and it obscures intent. The new function avoids such pitfalls,
improves readability, and makes the intent explicit:
(hash-table-contains-p key table)
The name 'hash-table-contains-p' exists in other Lisp dialects (e.g.,
SRFI-125), and follows the precedent of 'seq-contains-p'. Other
alternatives considered include `hash-table-has-key-p` and
`hash-table-key-exists-p`, but none were clearly better.
This was previously discussed in 2018, and all comments were positive,
but the proposed patch (implementing it in C) was never pushed:

(C_LANG_NAMES_INDEX): New macro.
(print_language_names): Do not assume etags.
(PROGRAM_NAME): Remove. All uses removed.
(print_help): Document --ctags if PRINT_UNDOCUMENTED_OPTIONS_HELP.
(main): Support new --ctags option, and support all [ce]tags options.
* test/manual/etags/Makefile (CTAGS_PROG):
Now etags --ctags, since there is no longer a ctags.
Fix possible wrong result of `string-pixel-width' with alternate
and default properties. Create new regression tests.
* lisp/emacs-lisp/subr-x.el (string-pixel-width): Like for
`face-remapping-alist', use in work buffer the value of
`char-property-alias-alist' and `default-text-properties'
local to the passed buffer, to correctly compute pixel width.
(Bug#77042)
* test/lisp/misc-tests.el: Add tests for `string-pixel-width'.
