Description Ismail Donmez 2003-08-18 09:10:55 UTC

Version:           1.2 post (using KDE 3.1.9)
Compiler:          gcc version 3.3
OS:          Linux (i686) release 2.6.0-test3-mm2

When I convert my encoding to tr_TR.UTF-8 pasting a text to console gets very slow that
I can see all characters get pasted one-by-one. If I set my encoding to tr_TR again
text pasting is very fast that its almost instant.

is this a Qt bug?

Comment 2 Oded Arbel 2004-05-09 13:02:36 UTC

I confirm this happening with Mandrake's cooker RPMs from today. 
When the locale is in UTF-8 (I tested with en_US.utf-8) then pasting gets slow after about 2 lines and keeps getting slower - at 10 lines or so I can actually see each character being typed by the konsole (I'm using a maximized konsole- a line is about 150 characters or so). 
When I set the locale to en_US and then relaunch konsole, pasting is immidiate.

Well I dont have the problem.

Some informations:

$ locale
LANG=fr_FR.UTF-8
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"
LC_COLLATE="fr_FR.UTF-8"
LC_MONETARY="fr_FR.UTF-8"
LC_MESSAGES=C
LC_PAPER="fr_FR.UTF-8"
LC_NAME="fr_FR.UTF-8"
LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=
$

Distribution: Debian-testing
Version: Konsole 1.4.1 (using KDE 3.3.1)


Test:
 Opened a he text ( available at:  http://cvs.sourceforge.net/viewcvs.py/wikipedia/phase3/languages/LanguageHe.php?rev=1.36&view=auto ) with kedit. Selected it all, copied.
 In konsole : opened vim, pressed i, pasted.

Not instant cause the terminal had to scroll, but it was very fast (at least as fast as pasting ascii text).

Comment 4 Oded Arbel 2005-01-15 16:36:46 UTC

Same here. just retested after upgrading to konsole 1.4.2 (kde 3.3.2) using RPMs from Mandrake's cooker, and no delays in pasting.

Thx to whomever fixed it !

Comment 5 Ismail Donmez 2005-02-04 21:02:06 UTC

Still slow here.

Comment 6 Waldo Bastian 2005-02-05 01:23:02 UTC

I was under the impression this was actually a problem with the "readline" library... please check if pasting is fast if you run "cat > /dev/null" from the shell.

Comment 7 Ismail Donmez 2005-02-05 08:36:17 UTC

cat > /dev/null and pasting some arabic text works fine.

Comment 8 Waldo Bastian 2005-02-05 15:58:17 UTC

Ok, I can confirm that this is a readline problem. It got fixed in readline-5.0:

g.  Fixed a bug that caused the prompt to overwrite previous output when the
    output doesn't contain a newline and the locale supports multibyte
    characters.  This same change fixes the problem of readline redisplay
    slowing down dramatically as the line gets longer in multibyte locales.
