Mercurial Plugin doesn't handle transplanted revs

[Tim Hatch]

I used the hg transplant extension (which is bundled with core hg these days), and it seems to have set some binary metadata:

transplant_source='Y\xae\xb4\x0b\x96\x15\x0fg\xb3y\x96\xe0a\xa9\xe1\xa0\x07.\xf7\x10'

This causes display of changesets to choke because it's non-ascii. I suggest that the mercurial plugin attempt to do the unicode conversion itself to catch issues like this and be able to recover.

Error handling to turn binary into hexdumps, and if something else happens just show the repr

[Tim Hatch]

Oh, forgot to mention that this is on a live site and that the error message is a standard UnicodeDecodeError. See ​http://dev.pocoo.org/projects/pygments/changeset/610%3Afe4c7d073655

Trac should likely just use mercurial.node.hex() on that property.

As transplant is a standard extension, it makes sense to write a small property renderer component for it. For the general case, we can do something like Tim proposed, maybe with a size limit?

Should be fixed in r7415 and 7416.

[Christian Boos]

Follow-up r7430 needed to fix a typo in r7416.

Btw, any issue on the pocoo site preventing the fix to be applied?
