Description

The recently committed mercurial repository can not be read with old mercurial versions. For example, I'm getting the following error with hg 1.3:

abort: requirement 'dotencode' not supported!

In r4676, I replaced the tar.gz fixture with a hg bundle and adapted the rake task to setup the test repository. Tested with hg 1.3 and 1.7.

Toshi, can you check that it's OK?

  3. For compatibility with hg < 0.9.4 (Jun 2007): 'hg clone --config format.usestore=False --pull'

r4676 is great idea.
I confirmed source:trunk/test/fixtures/repositories/mercurial_repository.hg@4676 is compatible with Mercurial 1.0.

$ hg clone -U http://selenic.com/repo/hg hg-stable
$ cd hg-stable
$ hg update 1.0
$ make local
$ LANG=C ./hg --version
Mercurial Distributed SCM (version 1.0)


$ LANG=C /somewhere/hg-stable/hg unbundle ../mercurial_repository.hg
