diff between two arbitrary revisions

[Matthieu Moy]

Hi,

I'm just waking up a new thread:

  http://article.gmane.org/gmane.comp.version-control.bazaar-ng.general/4627

The problem was that bzr's command-line didn't allow calling "bzr
diff" between two arbitrary remote revisons. Several solutions were
proposed, but AFAIK, no decisions were taken.

1) changing the namespace to allow, for example

bzr diff -r revno:42:http://path.to/branch..revno:24:http://path.to/other

2) use a fragment in the url

bzr diff -r branch:http://path.to/branch;revno=42.. ...

3) change the UI, but not the namespace

bzr diff --branch http://path.to/branch -r 42 \
         --branch http://path.to/other  -r 24


In the meantime, "bzr diff" was modified to accept two branches as
input, so

  bzr diff path/to/file1 path/to/file2

is a limited diff, but

  bzr diff path/to/branch1 path/to/branch2

is an inter-tree diff. Also, one can diff two revisions of the same
branch with

  bzr diff -r 24..42 /path/to/branch/

This goes in the direction of 3) above, but isn't sufficient, because
it doesn't allow you to specify a revno for the branches. Moreover, it
accepts only local branches.

So, what are the plans, finally ?
