SOS 4.0 Concurrency problem

gadzuk · Post by **gadzuk** » Mon Apr 26, 2004 12:50 pm

I've turned on SOS 4.0 as my source control provider.

I'm crashing the SOS server. Steps to reproduce:
Open SOS client
Access SOS functionality in VS.Net (two concurrent connections from my PC).

When I start VS.Net (Enterprise Architect) and choose "File / SourceControl / Open From Source Control", I get the following...

Code: Select all

To ensure optimal source control integration with Visual Studio .NET, check with your source control providver for compatibility and update information.
Installed provider: SourceOffSite
Installed version 4.0.0.135

I then get the SOS login prompt

and VS.Net hangs. My other SourceOffSite window loses connection with the server. The server has died and needs to be restarted.

The server log (dying words) looks like this:

Code: Select all

4/21/2004 5:37:20 PM - Connection accepted from 10.21.9.2:4058, session id is 8.

Thoughts?

PS Seems to work if I can remember to close my existing SOS window.

Haven't tried other combinations yet (e.g. two SOS windows), this is my 5th server reboot so just getting a handle on how this product will work for us.

An update...

The simpler steps to reproduce (without crashing VS.Net).

Open SourceOffSite
Open a 2nd SOS.

The 2nd instance fails to connect, the 1st instance loses the connectoin.

The SOS server service must be restarted.

Server's dying words:

Code: Select all
