bzr crashed with InvalidCommand in abort(): line 982657: Invalid command ' lead_in'

[James Gregory-Monk]

I am trying to do a fast-import into Bazaar from a Git repository. I've already done a fast-export (both directly from Git and via the fast-export-from-git command in Bazaar) to get the .fi file. However, if I try to either extract the info or import the repository, Bazaar fails with the above error.

It would appear that the fast-import command is attempting to evaluate the 'lead_in' command used to initialise a rspec blueprint. The offending line (with some context) is as follows:

982655 M 100644 :7134 spec/blueprints/documents/sjt_document_blueprint.rb
982656 M 100644 :7135 spec/blueprints/sjt_blueprint.rb
982657 lead_in

This looks like a broken fastimport stream to me. Does "git fast-import" import it correctly?

[James Gregory-Monk (jamgregory)]

Hi Jelmer,

Ah, git fast-import also fails with the same thing:
fatal: Unsupported command: lead_in

My question then is, why is Git exporting a stream that is broken?

I'm afraid I'm not very familiar with git fast-export, so I can't really
help you with that.

If you're looking at importing a Git branch into bazaar you might want
to have a look at bzr-git.

Cheers,

Jelmer

It does appear to be a bug in git fast-export - if I try to export it with --no-data, it exports those lines as well (despite that being blob data, as far as I can tell).
