I’m using Mercurial 1.7 from MacPorts to sync with OpenJDK sources. This operation is usually done with hg fclone

[bash] hg fclone http://hg.openjdk.java.net/bsd-port/bsd-port [/bash]

fclone came from forest

Mercurial 1.7 changes some API and call to do_read should be changed to _call.

Hopefully, I found a maintained Forest for Mercurial by GXTI and they now handle correctly pre/post Mercurial 1.6 or 1.7.

To install this updated extension.

hg clone https://bitbucket.org/gxti/hgforest

Make sure this forest.py is included in your ~/.hgrc
