Hanging app with SVNSCC 1.6.0

Hi,

I have tested version 1602r with regard to the progress dialog settings. I
found the new Progress Dialog Settings... button and turned on Show and
Close progress dialog. This now seems to work without making WayPointer
hang.

I have now got the same error message with two documents open as well, so
it probably doesn't have anything to do with the number of documents. The
progress dialog displays:

Get extended info for : C:\dev\svnws\r1\model1

I received your note about testing version 1602r. The link was to my other
case, but I received an error message that may be of value for this case:

Access violation
File - C:\Program Files\PushOk Software\SVNSCC\svn\svncom.dll
Offset - 0x00016be8 Line 635

This actually happened with only one Word document open. With two documents
open I haven't got an error yet. So it seems this version is more stable.

Success!

I tested turning off "PushOk SVN Proxy properties/SVN options/Show progress
dialog for operation longer than..." and now WayPointer doesn't hang
anymore. So there we have the problem, apparently displaying the progress
window doesn't not work with WayPointer. Why this is I do not know, maybe
you can find out you can reproduce the problem using my instructions below.

Hi,

I have today again tried going back to 1.5.1.3, which works fine. Then I
installed 1.6.0 RC2, and WayPointer again hangs. I have also tried using a
mutex around all calls to SVNSCC, just in case some call might not be
thread-safe, but that didn't help.

Now that you have WayPointer, this is how you can reproduce my problem:

0. Using Subversion 1.6, have a 1.6 working copy ready. Say for example
C:\wc16.

1. Start WayPointer.

2. Run Tools->Configure version control. Under "Add verion-controlled
folder", select "PushOk SVNSCC" as provider and click Next. This will show
the familiar SVNSCC interface for selecting SVNURL, module and local path.
Enter the details for local path C:\wc16.

3. Now that version control is configured, select File->Save and save the
WayPointer project file as C:\wc16\proj1.wpp (i.e. save the project file in
the svn working copy folder).

4. WayPointer will now detect that the project file is version controlled,
and you will see a rule trigger that allows you to check-in the file.
However, whatever you now do with the WayPointer window, even if you just
try to drag the window to a new location, the application hangs.

Please try this and see if you can reproduce my problem.

Magnus

Hi again, I've been busy but am debugging this again now. The problem I see
is that our application first makes some successful calls to SVNSCC. The
application looks OK, but as soon as I click on anything in the application
window the following happens:
1. First there is a delay when nothing happens, maybe 2-3 seconds.
2. The the window "blinks", the window title displays "Not responding" and
the spinning wait cursor is displayed.
3. The application hangs completely. Connecting with a debugger does not
show that any of the C# threads are hanging in strange places. The CPU
usage is 0%.

I have added trace output to see if the app is hanging in a SCC call. That
does not seem to be the case.

I have tried to extract our SCC integration code into a separate smaller
app to isolate the problem. I can't really get the problem to happen in the
debug app, but I do see some strange hanging "windows" from SVNSCC. See the
attached screenshot.

Is it possible that there are threads in the SVNSCC dll, that could be in a
deadlock?

OK, here are the new log files.

Regarding WayPointer, it is not an IDE but a process guidance tool. It also
helps users check in and check out files when needed, which is why we use
the SCC api. In addition to WayPointer you would need to install a modeling
tool like our Essential Modeler. I can help you set this up if you want.

OK, using the debug dlls, the first thing I notice is that I now get these
exceptions in our app WayPointer:

External component has thrown an exception:
System.Runtime.InteropServices.SEHException

I get this a few times, then WayPointer hangs when I try to open one of the
menus in the menu bar. Attached are debuglog.txt and protocollog.txt.

I chancked this in 1.6.0 RC2, and I'm still seeing the same behavior.

Hi,

Our product, WayPointer, has an SCC integration. We have successfully been
using the 1.5.x versions SVNSCC together with WayPointer. Recently I tried
to upgrade to the new 1.6.0 RC0 version. Mostly it worked well with VS.NET,
but not with WayPointer. When used with WayPointer, the application will
suddenly hang and I have to kill it using the Windows Task Manager.

I have tried to connect to the app with the VS.NET 2005 debugger to see
where in the code it is hanging, but I can't see anything out of the
ordinary. We have around 20 threads in the app, but all of them appear to
be in expected places in the code and none of them are hanging in any SCC
functions. So I can't see what could be wrong.

I downgraded to SVNSCC 1.5.1.3 again, and now WayPointer works again, so I
am fairly sure that the problem is with SVNSCC 1.6.0 RC0.

Any ideas?
