Description Juergen Funk (CIB) 2018-11-07 05:51:42 UTC

Problem: cppunittester.exe

After Build it make the unit-test with the cppunittester.exe, but the cppunittester.exe hang, and on the Jenkins-slave kvm-windows 10 machine can not shoot down the processes. 
In some cases in the process-list you can see 1 to 8 cppunittester-proceses. On my Laptop with Win10 i can kill this prcesses, and it's not always, but on the kvm-windows10 it's always.

A stack-trace follow in Comment 1

Comment 1 Juergen Funk (CIB) 2018-11-07 05:58:12 UTC

This following stack-trace this was made on my Laptop Windows 10, in the process-list it hang two cppunittester.exe, and the stack-traces was identical except the pointers.
Here the trace:

Tipp: is better you copy in your own editor, all steps in one line

Comment 2 Markus Mohrhard 2018-11-07 06:23:37 UTC

There should be another thread. We need backtraces for all threads to have an idea why the main thread is blocked in the mutex. Seems that it is somehow related to the clipboard thread which might do some stupid stuff.

Comment 3 Juergen Funk (CIB) 2018-11-07 06:35:11 UTC

Morning Markus, so early

you right i see two other threads with the clipboard-stuff, i post this asap.
A other info i test with LO6.1.4

I think the other threads are unimportant (wsupdate, GdiPlus, 4x TppWorkerThread)

Thanks for help

Comment 5 Jan-Marek Glogowski 2018-11-07 07:06:28 UTC

An additional missing information is the SolarMutex structure, which holds a member with the thread id of the process / thread locking the mutex. This implies you need to post a consistent backtrace of all threads with their TIDs.

Recently there was a commit from Mike using a newer API to handle the Windows clipboard, which might also help, but still the main problem is to understand why just you are seeing those assumed deadlocks. It may help to update your build environment (Cygwin + MSVS) too.

it is right the backtrace in Comment 1 was from yesterday, now here the first backtrace again and compatible to Comment 4

I absolutely can not understand how the second thread can be stuck. The thread is in the windows API inside calls that look like throwing a SEH exception. IF none of the COM methods called are actually catching SEH this should theoretically result in a crash (we no longer handle SEH as normal C++ exceptions and therefore should not catch them).

Thanks for stripping down the backtrace. I didn't originally check, but this is really in the clipboard code.

This was merged on Monday, which might be related:

Win: implement Clipboard Format Listener instead of obsolete Viewer

Just try reverting the latest patches in dtrans and see, if this helps, as you can hopefully easily reproduce these deadlocks.

The problem is in the 6-1 branch which does not contain the new code. However, it might be interesting to see if these commits by Mike actually help by building master.

Comment 11 Juergen Funk (CIB) 2018-11-08 06:10:35 UTC

Hi Jan & Markus,

thanks for the help, i think the problem here is the clipboard-chain, i have a own application with clipboard-chain and when LO hang, debugging or crashed then my program hang too, i will try too insert the listener too.
An for LO i want backport the patch from Mike and i hope, no i think that solved the problem. 

But the other quetion here is, why it come in this state, it is possible when every LO-Instance open her owen clipboard-chain and the last one crashed, or end not normally (an application inserts itself into the clipboard-chain, it is always on the top of the chain), then the other LO-instances hang.

Maybe this is the case that a previous LO instance had a problem and caused this state?

Oh - shouldn't post in the night when tired...

I have an other idea. Maybe it's the fix for bug 118573.
The fix is just correct, if my original conversion to Application::Reschedule() is allowed here. Can you check if reverting that patch helps?

Comment 13 Juergen Funk (CIB) 2019-02-15 07:06:55 UTC

Hi Jan, Markus

We have implement the cygwrapper (is in lode) on the kvm-windows-machine and with this, the mainly hangs disappeared.
But when hangs then you can shoot up the hanging processes.

But why it hang sometimes on my Laptop that is not clear.

Comment 14 QA Administrators 2021-02-15 04:07:56 UTC Comment hidden (obsolete)

Dear Juergen Funk (CIB),

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Feel free to come ask questions or to say hello in our QA chat: https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

The problem was solved with new clipboard-handling (comment 9), and a other call in jenkins-job
