Import of https://code.launchpad.net/~lyx-outline-devel/lyx/lyx_2.0.x not importing

Asked by Rainer

The branch

https://code.launchpad.net/~lyx-outline-devel/lyx/lyx_2.0.x

is not importing any more for the last 15 hours and gives an error message

Notes for the next CHR person:

abentley looked at the error. He saw two issues.

1) "This looks like a timeout. The import system kills timed-out workers with SIGINT. I think what's happening is that repacking is taking too long and not giving enough progress updates, so the import system concludes that it's hung. [T]his could probably be fixed by having a LOSA manually issue "bzr pack" on the branch."

2) "...[T]he following failures were different. e.g. bzrlib.errors.PathError: Generic path error: '4d28ec951c2cd6f54f2f6567909f2054.rix': Failure: unable to rename to '../indices/4d28ec951c2cd6f54f2f6567909f2054.rix' You'd have to get a losa to examine the branch, but I suspect the repository is broken. Probably has an ../indices/4d28ec951c2cd6f54f2f6567909f2054.rix without the rest of the related files."

I had a few tasks following this discussion. For the immediate problem with this branch, get a LOSA to try bzr pack, and then to try deleting the branch. For the longer term problems, file bugs (from abentley again: "There are at least two bugs; the repack timeout, and the inability to continue after the repack timeout.").

I went to LOSAs, asking them to find the branch and then do the following. "...[F]irst try a bzr pack. If that works, stop--let's see if that makes things better. If not, please delete the repo for that import, and we'll hope it is better.". gnuoy responded and tried unsuccessfully to find the branch on the machine. abentley shared my impression that it should exist despite the import failing, but was not confident. gnuoy EoD'd and no other LOSAs are available until Monday.

Suggested follow-ups to next CHR:

 - File two bugs per abentley's descriptions above.
 - Contact LOSAs Monday morning to pursue the steps I asked for (find branch, try bzr pack, and then delete the repo if that doesn't work/doesn't help)
 - If LOSA cannot find branch, contact mwhudson or thumper and ask for assistance.

We have verified that the branch does not exist, and so we cannot pursue the bzr pack or repo deletion strategies. The next step is to contact mwhudson or thumper and ask for assistance, which I am doing now.

Hello: after getting some direction from Gary (thanks again), we found the offending branch on our servers, did a bzr pack, and re-tried the import, and that seemed to work fine.

The Branch should be imported and stay synced properly now.

Regards, Stefan
