* src/regex.h (RE_DUP_MAX): Raise limit to 2^16-1.
* etc/NEWS: Announce it.
* doc/lispref/searching.texi (Regexp Backslash): Document it.
* test/src/regex-tests.el (regex-repeat-limit): Test it.
* src/regex.h (reg_errcode_t): Add REG_ESIZEBR code.
* src/regex.c (re_error_msgid): Add corresponding entry.
(GET_INTERVAL_COUNT): Return it instead of the more generic REG_EBADBR
when encountering a repetition greater than RE_DUP_MAX.
* lisp/isearch.el (isearch-search): Don't convert errors starting with
"Invalid" into "incomplete". Such errors are not incomplete, in the
sense that they cannot be corrected by appending more characters to
the end of the regexp. The affected error messages are:
- REG_BADPAT "Invalid regular expression"
- \\(?X:\\) where X is not a legal group number
- \\_X where X is not < or >
- REG_ECOLLATE "Invalid collation character"
- There is no code to throw this.
- REG_ECTYPE "Invalid character class name"
- [[:foo:] where foo is not a valid class name
- REG_ESUBREG "Invalid back reference"
- \N where N is referenced before matching group N
- REG_BADBR "Invalid content of \\{\\}"
- \\{N,M\\} where N < 0, M < N, M or N larger than max
- \\{NX where X is not a digit or backslash
- \\{N\\X where X is not a }
- REG_ERANGE "Invalid range end"
- There is no code to throw this.
- REG_BADRPT "Invalid preceding regular expression"
- We never throw this. It would usually indicate a "*" with no
preceding regexp text, but Emacs allows that to match a literal
"*".
* lisp/isearch.el (isearch-suspended): New defvar.
(with-isearch-suspended): Set isearch-suspended to t
at the beginning, then set it back to nil at the end.
* lisp/comint.el (comint-history-isearch-backward)
(comint-history-isearch-backward-regexp): Set global value of
comint-history-isearch to t.
(comint-history-isearch-end): Reevaluate
comint-history-isearch when isearch-edit-string finishes.
* lisp/dired-aux.el (dired-isearch-filenames)
(dired-isearch-filenames-regexp): Set global value of
dired-isearch-filenames to t.
(dired-isearch-filenames-end): Reevaluate
dired-isearch-filenames when isearch-edit-string finishes.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
The function `binding' may call isearch-done, which globally sets
overriding-terminal-local-map to nil (Bug#23007).
* lisp/isearch.el (isearch-mouse-2): Don't bind
overriding-terminal-local-map around the call to `binding'.
(isearch-lazy-highlight-update): Check it to decide whether to apply
overlays only on the selected window.
* lisp/follow.el (follow-mode): Set isearch-lazy-highlight to ‘all-windows’.
(Bug#17453, bug#21092)
* lisp/isearch.el (lazy-highlight-max-at-a-time):
Change default value from 20 to nil to not trigger redisplay
between updating iterations.
(lazy-highlight-cleanup): New arg ‘procrastinate’ to not remove
overlays when non-nil.
(isearch-lazy-highlight-new-loop): Call lazy-highlight-cleanup
with non-nil second arg when the search string is not empty.
Run timer with isearch-lazy-highlight-start instead of
isearch-lazy-highlight-update.
(isearch-lazy-highlight-start): New function. (Bug#25751)
* lisp/isearch.el (isearch-new-nonincremental): New variable.
(with-isearch-suspended): Bind isearch-new-nonincremental to
isearch-nonincremental, and restore it afterwards.
(isearch-forward-exit-minibuffer, isearch-reverse-exit-minibuffer):
Set isearch-new-nonincremental to nil. (Bug#25562)
to t to display "Pending" in the search prompt for lax
word/symbol search (bug#25562). Don't use lax for lazy-highlighting
when 'bound' is non-nil.
(word-search-regexp, isearch-symbol-regexp): Don't depend on lax
at the beginning of regexp (bug#22589).
* lisp/info.el (Info-isearch-search):
Use isearch--lax-regexp-function-p.
* doc/emacs/search.texi (Word Search, Symbol Search):
Mention "Pending" prompt for lax word/symbol search.
* lisp/isearch.el: Add `isearch-scroll' property to
universal-argument-more so that `isearch-allow-scroll' will apply to it
as well.
(isearch-pre-command-hook): Let `isearch-allow-prefix' apply to
`universal-argument-more' as well (Bug#25302).

It is useful to be able to call `isearch-done' unconditionally to
ensure a non-isearching state.
* lisp/isearch.el (isearch-done): Check that `isearch--current-buffer'
is a live buffer before using it (Bug #21091).
* test/lisp/isearch-tests.el (isearch--test-done): Test it.
(cherry picked from commit 68f4b52927)
It is useful to be able to call `isearch-done' unconditionally to
ensure a non-isearching state.
* lisp/isearch.el (isearch-done): Check that `isearch--current-buffer'
is a live buffer before using it (Bug #21091).
* test/lisp/isearch-tests.el (isearch--test-done): Test it.
Make the documentation of the search functions more accurate,
complete, and uniform; in particular, extend the description of
the effect when the 'count' parameter is a negative number to all
of these functions.
* src/search.c (Fsearch_backward, Fsearch_forward)
(Fre_search_backward, Fre_search_forward)
(Fposix_search_backward, Fposix_search_forward):
* lisp/isearch.el (word-search-backward, word-search-forward)
(word-search-backward-lax, word-search-forward-lax): Improve doc
strings as described above.
* doc/lispref/searching.texi (String Search, Regexp Search)
(POSIX Regexps): Use 'count' instead of 'repeat' as the name of
the fourth parameter of the *-search-{forward,backward} functions
and improve documentation as described above.
Problem reported by Jan Synáček.
Solution suggested by Stefan Monnier (Bug#23519).
* lisp/isearch.el (isearch-mode-map): Add a binding for xterm-paste.
(xterm--pasted-text): New decl.
(isearch-xterm-paste): New function.
* lisp/term/xterm.el (xterm--pasted-text): New function,
taken from xterm-paste internals.
(xterm-paste): Use it.
* isearch.el (isearch--describe-regexp-mode): The `description' var
needs to always be a string. Add the missing default case for the
cond form that ensures that.
Before this bug fix, for the events when `regexp-function' and
`search-default-mode' both were nil, `description' also stayed nil. So
when `space-before' was non-nil, the "non-string" `description'
(with a value of nil) got passed as an argument to
`replace-regexp-in-string' (where a string was expected). That caused
the error described in Bug#23038.
* lisp/isearch.el (isearch--describe-regexp-mode): With
`search-default-mode' set to nil, if user does C-u C-s, the minibuffer
now displays "Regexp I-search: " again. But if the user has set
`search-default-mode' to t, and then does C-s, the minibuffer now
displays "I-search: " because the default search mode is now regexp
mode. Comments have been added to explain the priority of conditions
in the `cond' form. (Bug#22991)
* doc/lispref/windows.texi (Window Start and End, Textual Scrolling)
* doc/lispref/positions.texi (Screen Lines): Remove optional GROUP argument

pos-visible-in-window-group-p, recenter-group and move-to-window-group-line,
together with the six variables indirecting to the pertinent group
functions.
* src/window.c

applies to these two files, which added the GROUP argument to six window
primitives.

functions.
