Squish: build server crashes in C runtime library

[Tom-Willemsen]

As a developer I would like the squish tests to run correctly.

I updated squish on the build server to enable it to run the new java 11 GUI, but the new version of squish hangs with the following error when launching each test:

On pressing "ok" the test seems to continue and run correctly, but while the pop-up is open the process is hung and the tests can't proceed.

If after brief investigation we get stuck, contact squish support for help diagnosing the problem.

Have sent an email describing our problem to squish support - awaiting response

After some back-and-forth with Squish support (who were very responsive and helpful), we have narrowed this down to Python's uuid library loading an incorrect C runtime version. We use the uuid library to generate random names in a number of places.

Possible solutions:

• Rename C:\Squish\python\msvcr90.dll to msvcr90_off.dll on the build server
• Don't use the python uuid library - instead replace it with any other library that can give us randomised strings

File renamed on build server and note added to wiki with error text and solution.

How many points?

This seems like a bit of a hack and will continue to be a pain when every developer installs squish. Why not just stop using uuid and generate a random string ourselves? It's not like we need it to conform to UUID especially?
