Mercurial: "abandoned transaction found - run hg recover". Recover does not work

Using tortoise hg on windows, I did a pull from a repository on my local drive to a repository on a usb stick.

During the pull i guess there was a glitch in the usb-connection because it got aborted half way through.

Now i can't pull again. I get the message: abandoned transaction found - run hg recover

When i run hg recover i get the following message:

rolling back interrupted transaction

If i try to rollback manually i get this message: no rollback information available

This time i can quite easily just delete the whole backup on my stick and do a fresh pull because the repo is small and the usb-stick does not contain any other changes. But what if this happens on a larger repo where i can't afford to restart from scratch? How can i recover the repo?


I experienced a similar issue and reported it as a bug, and the developer on the report suggested the problem is a corrupt journal. As described in the bug report, you can run hg verify to see the last "good" commit, and use hg clone -r <#> to recover up until that commit.


I think this is actually a bug in the code source. You should report the error to the Mercurial team like said in the error message.


I was using the TeamCity CI and Deployment server, so, probably, this is another issue, but I have posted the answer to the similar question.
