Is there some way to just get the tip from mercurial? eg only the
latest sources and not the whole repo?
This is a bad idea. Bazaar has this feature, they call it
"lightweight checkouts". It adds a lot of complexity to the
implementation, and what is worse, it seems to confuse users.
Basically, not worth it for the purpose of casual checkouts.
(Developers use it because it's the only way to share the repo in
Bazaar, and they have pretty sucky space efficiency, so it ends up
saving a lot of space if you have multiple branches checked out.)
And unnecessary, IMO. As Mike points out, Mercurial history storage
really is efficient. Here's a du for my current XEmacs workspace,
with almost 4500 changesets:
chibi:xemacs steve$ du -sk . .hg ./+*
chibi:xemacs steve$ find . -name '*.elc' | xargs du -ck
chibi:xemacs steve$ find . -name '*.info' | xargs du -ck
So the working tree takes up 110 MB (13MB of Lisp), C build products
40~50MB per build, Lisp and Info build products about 5MB per build,
and Mercurial repo data only about 12MB.
I don't see any reason why the packages would show a metadata ratio of
as much as 20% of the source tree, while build products run about 40%
for Lisp. Surely that's acceptable?
