Hi, i'm the PM of Sogou IME for Mac. We are still working on to reproduce
the bug although it happens to us everyweek, and users report it too:

Greetings,

Thanks for your bug report.
Does this issue happen only on Lion or does it happen also on Snow Leopard?
(Unfortunately, I cannot log into weibo.com and cannot read all reports
except
<http://pinyin.sogou.com/bbs/viewthread.php?tid=520417&highlight=chrome>.)
Technically, Chrome implements NSTextInputClient to receive IME events.
Chrome returns without blocking for all NSTextInputClient methods except
the following three methods:
* [NSTextInputClient characterIndexForPoint:];
* [NSTextInputClient firstRectForCharacterRange:actualRange:], and;
* [NSTextInputClient attributedSubstringForProposedRange:].
Unfortunately, these methods uses blocking calls and they may take long
time (~1.5 seconds). Instead of using blocking calls, a renderer may send
notification messages to a browser every time when the rednerer updates
these values?

Hello,
I am a developer of Sogou IME for Mac。
I confirm that we did not use the following NSTextInputClient methods ：

* [NSTextInputClient characterIndexForPoint:];
* [NSTextInputClient firstRectForCharacterRange:actualRange:], and;
* [NSTextInputClient attributedSubstringForProposedRange:].

We use the NSTextInputClient methods as follows：
- (void)insertText:(id)aString replacementRange:(NSRange)replacementRange;
- (void)setMarkedText:(id)aString selectedRange:(NSRange)selectedRange
replacementRange:(NSRange)replacementRange;

So, we can confirm that is not the NSTextInputClient methods problem.

OK. I am actually not the one who found the problem, but someone else
brought it to my attention. I think the one who found the problem is not a
Googler.

Is this necessary to fix the bug? If so, maybe we could contact that person
and try to fix it.

I was the one who found the problem, we think it might be Chrome's issue as
we found same complains from users who are using other Chinese Pinyin IME
and Chrome, such as QQ Pinyin IME for Mac, and Sogou do not have the same
problem in Safari or Firefox. So we need Google's help to solve it.

We will have the new beta version of Sogou IME for Mac released in two

We've found a bug in Chrome .

if you use Chrome to open a html like below :

<html>
<head>
</head>
<body>
<h2>Maxlength Test</h2>
<input maxlength="10" />
</body>
</html>

Select any input method like apple's official Chinese input method.

click text field and than input something quickly , when the characters of
the input field over 10 (which is declared in html as "maxlength") , you
will see input method has been blocked, after for awhile Chrome has
crashed .

as we test Safari and Firefox don't have the problem , seems chrome has a
bug when process the "maxlength"

Another report from MacIdea, the famous Mac Fan bbs in China, this time it
is QQ IME (http://shurufa.qq.com/mac/)

ML下，QQ输入法你们会卡么
有的时候在chrome下。有文字输入的地方，打字有的时候就卡到不行。。
整个电脑就停在哪种的感觉

in ML, dose it ever stuck with QQ IME?
sometime in Chrome, when you type, it stucks and makes you lose patience.
the whole computer is like freezing

leizhao4@

Thanks for the repro!
We were able to see the issue first hand.
It seems that the issue is more likely to happen on Lion than Snow Leopard.
I did manage to get the issue on Snow Leopard but only with a chinese IME
and by pushing it very farm in terms of expectations (insanely fast and
therefore non sencical typing). It was much easier to trigger the issue on
Lion and seemed to happen on any type of IME.

Does this match your own experience?
Also, is the typing speed required to trigger the issue something
reasonable?

Thanks.

@kenjibaheux except the way you repro （insanely inputting), there are
another two ways to repro:
1 open a few tabs, switch between tabs and type fast and randomly (with Any
Chinese Pinyin IME), chrome will encounter a crash (freezed for a long
time), i recorded a video for this and mailed it to rgilbert and suzhe
2 open chrome and visit baidu.com, type right away and chrome freezed for a
long time, this can not repro everytime, but im sure you will encounter
this you keep on using Sogou or any other Chinese IME for a week (for daily
work, not just doing it for a few minutes for tests)

Greetings,

(in reply to comment #45)

> Could you take a look at this?

Unfortunately, I do not have good knowledge about the current
NSTextInputClient code of Chrome. Even though I have implemented the
initial NSTextInput code long time ago, some people changed it without
notifying me and the current Chrome does not use NSTextInput any longer. It
is definitely better for those who implemented the current TextInputClient
code to work for this issue.

@kenjibaheux

Thanks for confirming this. I don't remember I got this issue on Snow
Leopard, but I haven't been using SL for like 10 months so I'm not quite
sure about that. And I don't know if it's because of the Lion or a Chrome
upgrade.

On Lion, I don't need to be insanely fast to trigger it. Just as fast as
normal (~5 keystrokes per second I guess).

Another thing I noticed is, after the long freeze, some of the keystrokes
are duplicating. For example, when I type "pinyinshurufa" for "拼音输入法",
I eventually get "ishurufa拼音输入法" after the freeze.

Thank you all for your effort.

I'm on Snow Leopard and have the issue as well--when quickly switching and
typing, if I go too fast, especially if I start mis-typing a word, the
whole browser hangs and then reverts exclusively to English. I then cannot
use the input method any longer. Occasionally, the entire browser hangs and
I have to do a Force Quit. If that doesn't work, which has happened at
least three times over the last two weeks, the only thing I can do is
re-boot by holding down the power key.

Are there any updates or fixes yet? It's very annoying because I am usually
working on multiple documents switching between English and Chinese and so
obviously it is not convenient when I have to reboot. (Luckily I have not
lost anything yet since I save often!)

Thanks!

jshin@ : Me too. I didn't mean the separate one (121468). I meant the same
issue (comment 0). And its description is not accurate enough
because "Sogou IME" is not a necessity to trigger it. Any IME I tested will
do.
