Updated TeamCity: Now Won't Checkout Mercurial

Well I didn't do a correct backup of my settings when I updated Team City and somehow lost all of my VCS roots but the rest of my settings for my projects are still there.

When I re-add my mercurial root, I test the connection and it succeeds, however when I try to run a build, it fails on checkout. Anyone know what this error means?

[Updating sources: agent side checkout...] Failed to perform checkout on agent: 'cmd /c hg pull <MERCURIAL URL>' command failed.
stderr: transaction abort!
rollback completed
abort: connection ended unexpectedly

stdout: pulling from <MERCURIAL URL>
requesting all changes
adding changesets
adding manifests
adding file changes

This was working before I mistakenly updated without backing up :(

I am using agent side checkout with a specified checkout directory (just like I was using before the update)

Any help would be greatly appreciated.

[EDIT]: I updated tortoise hg / mercurial on the build server and got this error when trying to pull:

% hg --repository D:\Mercurial\Core pull --verbose https://<user email login>:<pw>@<kilnhg respository url>
pulling from https://<user email login>:<pw>@<kilnhg respository url>

I just tried开发者_如何学Python again from tortoise hg and the pull succeeded. This is very strange :-/

I've had the exact same problem. I have tried all available versions of TortoiseHG on my Windows 7 (64) machine. I can't clone or pull anything from anywhere :)

What solved it for me is the "Use uncompressed transfer" check box in TortoiseHG gui.

Equal to "hg clone --uncompressed"

I noticed a subtlety in your error message. You're using Kiln, right? I think this issue is explained on Kiln's support site. Can you manually pull from the repo to slowly pull chunks of revisions to see if it finishes with smaller sets using hg pull -r 200 as shown on Kiln's support site?
