Re: [Openexr-devel] Source Control

Interesting observation re the windows side ... 

I have no strong feeling against Hg; our Alembic team is running on with it and 
they seem quite happy.
The migration path from CVS to git seemed, at least the last time I looked, 
rather more straight forward with git.

My viewpoint is with a nod to perception of the wider acceptance of git over 
Hg, but then perhaps this reflects my *nix centric view of the world :)

Both git and Hg have been moving along nicely and have large
followings.  Hg seems to be better supported under Windows with a nice
GUI (e.g. TortoiseHg) and inuitive GUI access seems important for many
Windows users.  Git is more Linux-centric since it is originally
designed to support Linux kernel development by the Linux kernel
developers who use a particular development process.  Both are easy to
install.  The git repository requires some periodic maintenance
(re-compaction) whereas Hg's repository does not.

A benefit of Hg that is not immediately obvious is that since it is
based on Python, an Hg installation is assured to have a high-quality
scripting language available (i.e. Python).  Hg is easily extensible.
This should help with automating tasks (both build and version-control
related) without encountering the problem that Windows does not come
with a portable scripting language.

Recently I have been working to convert a large (and very old) CVS
repository to Hg.  A couple of years ago this conversion was not
acceptable (it failed due to a memory leak) but now the tools are
succeeding nicely and the quality of the conversion seems quite good.

The key deciding point for me to favor Hg over git was the nice
interface for Windows users and the assured availability of scripting.

What causes you to favor git over Hg?
