GSoC 2013: TortoiseHg cross-repo comparison of branches

[Giovanni Gherdovich]

Hello again,

I just added one idea to the Mercurial GSoC 2013 wiki page (item #11).

I report here the description:


=============================================================

integrate in TortoiseHg tools to compare branches from different repos

Currently TortoiseHg can inspect only branches
that belong to the same repository.
For instance, it is not easy to tell at which changeset
two branches have diverged, if those two are stored
in two separate repos.
Nonetheless it is not uncommon for a group of developers
to wander in what relation are their repositories/branches
between each other.
The version control system Bazaar have this feature,
and it is very appealing: multiple branches are shown together
in a single directed acyclic graph, possibly with multiple heads,
no matter where the repository come from.
This blog post gives an illustration of a similar
feature can look like: http://www.gghh.name/dibtp/?p=361

This project aims to provide TortoiseHg with the
aforementioned capability. This patch provide already
a possible starting point:
http://patchwork.serpentine.com/patch/940/

=============================================================


Needless to say that, accepted or not, funded or not,
I will be super happy of any kind of feedback you can provide.

So: does this project make sense in your opinion?
do you like it? Does it need rewording / reshaping?

As I said in the previous mail, I am volunteering to mentor
any student that could be interested in making this happen.

Cheers,
GGhh
