UnicodeDecodeError exception in clone command #331

Open johannesgajdosik opened 5 years ago

johannesgajdosik commented 5 years ago

I try to use hg-git for cloning a large git repo. After running 28 hours it gives me a UnicodeDecodeError. I would rather like that the cloning command could finish successfully. In my opinion the cloning should not be impossible just because some file in the repo contains a non-ascii character. There is not even a hint which file has the non-ascii char.

I have hg-git 0.8.11 and Mercurial 4.5.2, gentoo Linux.

Please have a look at this and tell me how to proceed. Thanks in advance!

I've hit this error when tags or named refs contain unicode. One fix would which will avoid cloning any tags or refs, would be to:

which should let you succeed in cloning.

good luck, hopefully this helps

Thanks for your reply and suggestion! The repository is huge and constantly used by many coworkers. My plan was not only to clone the repo with hg-git but to actually work with it every day. Removing the git tags and refs all over again each time I fetch or pull is not an option. Can you instead lead me to some peace of code that I can tweak so that the cloning can continue despite of having unicode tags and refs? Thanks in advance!
