code import from GitHub failing

Asked by Timmie on 2015-03-31

Dear maintainers,
plase have a look at the following repo:

https://code.launchpad.net/~pythonxy/pythonxy-upstream/python-pandas

the code import keeps failing.

The link to the log file:
http://launchpadlibrarian.net/201704434/pythonxy-pythonxy-upstream-python-pandas.log

What is the reason and how can we repair this?

Thanks in advance!

That's https://bugs.launchpad.net/bzr-git/+bug/1372149. The problem is that the Git repository was imported from Mercurial, and recent versions of hg-git add some non-standard commit headers that bzr-git doesn't support, and it isn't clear how they should be supported.

Practically speaking, it's unlikely that bzr-git will be fixed. These cases almost always appear when people are doing Git imports for source package recipes, and we expect to have them natively supporting Git later this year. We're currently rolling out initial native Git hosting support, and other features will follow soon.

To fix it before then you have little choice but to either rewrite the non-standard headers out of the repository, or maintain a rewritten branch that tracks master but doesn't include those headers.

Thanks for the swift answer.

This is interesting.

Code was initially at google:
https://code.google.com/p/pandas/

But since 2010 on https://github.com/pydata/pandas

by that time, the bzr import was set up and running well!

Will this include a automatic importer from github?

Can this be done by the pandas upstream maintainers on github?

Not too good since this would be a manual approach.

Thanks.

They must have recently merged a branch that was created by a new version of hg-git.

Not in the first round of features, but we want to do that very soon.

It's technically possible, but it's unlikely they'd do it -- it would effectively mean rebasing trunk.

It can be automated.

OK, I brought it to the attention of upstream:
https://github.com/pydata/pandas/issues/9831#

I will wait until the git feature will be available in LP.

Seem like bzr is dying a slow death. But it's the most user friendly contenders of the DVCS fight...

@wgrant

How will the git integration be announced?

A post on the
http://blog.launchpad.net/ ?

Yes, we'll blog about it.

Can you help with this problem?
