734727 - Hang when started locally then used over RDP

Status: RESOLVED WORKSFORME

(Thunderbird :: General, defect)

Description

[Konstantin Stefanov]

Attachment: Thread killing which sometimes unfreezes TB

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
Build ID: 20120215223356

Steps to reproduce:

I started Thunderbird locally (from the console). Then I went to another place an logged to the same session over RDP.


Actual results:

At first, ThunderBird was working, but when I presses 'Write' button to compose new message, new message window appeared but it did not respond (as Windows said) and the main windows did not respond too.

I run Process Explorer from sysinternals selected thread with 'GetTime' function and killed the thread (see attached screenshot). Then TB unfreezed, and I was able to compose message.

But the trick with killing thread does not always work, and besides if it works some strange effects are there:
TB does not exit (thunderbird process does not finish and I need to kill it via task manager or process explorer)
New account folder becomes full of unread messages (TB forgets which messages are read).
Some else strange did happen but I do not remeber the details.

Al these things do not happen every time I log on via RDP, but it happens quite often to be very annoying. I prefer to restart TB immediately after logging via RDP or logging locally when TB was started over RDP (all the same does happen).


Expected results:

TB should not hang when switched to RDP view.

I reproduced the bug with v11 (no windbg). Now I started TB with windbg, waiting for hang...

This hang was not like what I've seen before, but it happened in same conditions as previous, so I think it will be useful.

This looks like Core code - but I'm not really sure. How do you read the stack kyle ?

I think this is the thunderbird version of bug 714078.

As said in https://developer.mozilla.org/En/How_to_get_a_stacktrace_with_Windbg:
After hang occured Debug->Break in Windbg, then typed commands
|* ~* kp
|* !analyze -v -f
|* lm
In Windbg command line, then exited Windbg.

Where can I get it and is it possible to revert back to TB 11 after trying or I will have to create separate profile?

I installed TB 13.0a2, will try to reproduce.

Comment 14

[Konstantin Stefanov]

The bug is still in TB 13.0a2. I'll try to get stack trace.

Attachment: WinDBG log for hang on Earlybird 13.0a2

I've got another hang, adding log of WinDBG. It happened after "Software update" windows appeared.

Comment 16

[Konstantin Stefanov]

Seems that bug is not in EarlyBird 13.0a2 anymore. I think previous hang was not connected with this bug.

[Wayne Mery (:wsmwk)]

Thanks Constantin for all the testing.
We use WORKRSFORME, unless you think the failure was not in mozilla code.

Thanks for clarification. I was puzzled what to set and accedentally pressed 'Save Changes'
