Re: Git vs Monotone

I just read this blog post [0] in which one of the Pidgin devs sheds
his light on their 'tool choice'. In the post he mentions the
following figures:

The main thing this proves was that the Pidgin devs were most familiar
with Monotone, and weren't sufficiently familiar with git; hence, they
didn't know how to do a fair comparison.  First of all, sure, if they
are willing to use a single working directory and want to switch
between branches using "git checkout", that works well.  But suppose
they really want separate working directories.  The simplist and
easist way is to use "git clone -s".

So if they do:

git clone git://github.com/felipec/pidgin-clone.git pidgin
git clone -s pidgin clone-1
git clone -s pidgin clone-2
git clone -s pidgin clone-3
git clone -s pidgin clone-4
git clone -s pidgin clone-5
git clone -s pidgin clone-6
git clone -s pidgin clone-7
git clone -s pidgin clone-8
git clone -s pidgin clone-9
git clone -s pidgin clone-10

The net disk usage is 746 megabytes, as compared to the 900 megabytes
claimed in the blog post.  The main difference is the git database is
only takes 87 megabytes, compared to the 229 megabytes for the
Monotone database.  The main issue is the pidgin developers simply
didn't know how to use the -s flag so they didn't need to duplicate
the git database for every single clone.

Shrug; whatever, I've always said the biggest issue for any tool is
what the developers are familiar with.  It may be that monotone was
the right choice for the pidgin core developers, if they weren't
familiar enough with git.
