Mercurial extension no longer working after 4.7.1 upgrade
-
The Mercurial 4.4 extension does not load correctly with BuildMaster 4.7.1. The following error is reported on the extensions screen:
Could not load type 'Inedo.BuildMaster.Extensibility.Providers.SourceControl.IMultipleRepositoryProvider1' from assembly 'BuildMasterCore, Version=4.7.1.12, Culture=neutral, PublicKeyToken=112cfb71329714a6'.`This leads to the following stack traces in the logs when automated builds attempt to trigger:

Can you download Mercurial v4.5? That should include the relevant changes to work with BuildMaster v4.7.1

Updated the mercurial plug-in and it now loads correctly. We now have different bugs:
- Existing automatic builds no longer work
- Editing an existing automatic build and clicking "..." next to "Source path to monitor" crashes the server. The app pool repeatedly dies and sends the server into a 503 unavailable until it is manually restarted. There is no stack trace for this recorded in the Event Log but I may have crash dumps if you need them.
Deleting the Automated build and recreating it works fine - it's just a lot of grunt work. It seems we also need to go through and add names to all of our Mercurial repositories and update all references to them in our build scripts? Has this been a recent change?

In theory, you shouldn't need to add a name unless there are multiple repositories for a single provider - if that's not working as you would expect then that is a bug. All of our test repos for multi-repo providers have a name, but it still seems to work without one. If it's easy enough to add a name as a workaround, that's the best bet, and we can update the provider again in the meantime as to not require it as before.
