Subject: bug#22090: Isearch is sluggish and eventually refuses further service with "[Too many words]".
Date: Fri, 4 Dec 2015 04:20:52 +0000 [thread overview]
Message-ID: <20151204042052.GA1965@acm.fritz.box> (raw)
Hello, Emacs
With a recent emacs-25 (last update
eaa1fd6dbff8346eb38485de5ebf0fbfacf374d9 from Thursday 2015-12-03):
emacs -Q
C-c C-f src/xdisp.c
Move point to L30 (paragraph beginning "Updating the display is triggered
by the Lisp interpreter ...")
C-s
C-w repeatedly, to yank words onto the search string.
After ~29 words have been yanked, the response becomes sluggish, pausing
for between 0.5s and 1s before highlighting the "for" at the end of L31.
Carrying on with C-w, some words are taking 2 or 3 seconds to be
registered by Isearch. This is Bad.
After having yanked "you as part of" from L32,
(i) the " of" gets highlighted in the isearch-error face in the echo
area;
(ii) the text "[Too many words]" is appended to the echo area;
(iii) the highlighting is removed from the match;
(iv) point is placed at the start of the match (i.e. BOL 30).
At this point, <BKSP> will still behave as expected, except it's action
too is very sluggish - to remove two words from the current search took
several seconds.
Observation: it may be that C-w done in the vicinity of two or several
spaces experiences extra delay.
