Automatic builds with Mercurial

[Guest]

I'm running into an interesting issue. We host all our source in Mercurial. I initially setup a hook on our main repository to post to BuildMaster, but that created an infinite build when we started trying to label things. So, I've tried setting up a monitoring schedule, but I'm getting the following exceptions.

Unhandled Exception: System.FormatException: Input string was not in a correct format.

Any suggestions?

hi Chris,

What version of BuildMaster and the Mercurial extension are you using?

[Guest]

The latest for both.

I think I see where the error is occurring, likely when the provider is attempting to parse console output in order to determine whether to create a build or not based on the current revision of the source code in the repository. Can you tell me which version of Mercurial you're using? (hg --version)

Also, can you run the following command against the local repo (replacing {relative-path} with the same path you're using for the automatic build path):

hg log -y -v -l 1 "{relative-path}"

and paste the full output here?

I'm having the same issue, here's the info I get for the requested commands.

Thank you Bryan for the additional information - we were able to resolve the issue and have published a new version of the extension.

I know this is old but it's still the first thing that comes up in Google when you search for the infinite build issue in BuildMaster.

The infinite builds are because applying a label is technically a check-in in DVCSs like Mercurial and Git. So when you apply the label BuildMaster sees a new check-in and starts a new build, which applies a new label, which creates a new check-in, ...

I haven't found a good workaround yet.
