[Jython-dev] GitHub Jython repo broken

[Jeff A. <ja...@fa...>]

The master repository at https://github.com/jython/jython, recently 
migrated from Mercurial, has suffered some corruption in the process. 
Please do not use it until we work out how to fix it (or decide to live 
with it).

Ernest: please keep https://hg.python.org/jython/ safe: it's the most 
solid foundation we have at present.

Here and there, the translation process has lost the parent link from 
the first change set on a "topic branch". The effect is to make it look 
like the entire content of the repository is new at that change set. If 
you scroll back in the history of almost any file it stops (or rather 
begins) at the latest of these false roots. For information, we did this 
with a straightforward use of GitHub's migration tool, which produced no 
message that it was failing. (There were messages about linking 
contributor identities, which we addressed.)

We're sorry not to have noticed this sooner. If there is a way of fixing 
this it may involve a fresh start or some history-rewriting in situ. 
This will break forks you may have made. We will try to fix as much of 
this as we can from our side, but that won't be free of downstream 
annoyances.
