bazaar question

[henry atting]

I find it annoying that I have to grapple with bazaar if I
want to go on building emacs from source. Do I really have to pull
the whole emacs tree starting from the first published sources in the
Roman Empire?

Tried it with `bazaar branch http://bzr.savannah.gnu.org/r/emacs/trunk/'
but stopped, unpatiently, after 20 minutes.
Is this the only way to get the latest source?

You can get them from Launchpad too. That is faster since they have
installed the bazaar fast server (or what it is called).

  bzr branch lp:emacs trunk

After that updates are quick (in the trunk subdir):

  bzr update

You can do a lightweight checkout:

bzr checkout -v --lightweight http://bzr.savannah.gnu.org/r/emacs/trunk trunk

This takes less than 5min. on my system, fetching roughly 80-90MB of data.

If you don't need any history at all, you can simply get a tar.gz snapshot
from the git mirror:

The smart server works only if you have a Launchpad account and imported
a public ssh key there. Otherwise, it uses the http transport, the same
Savannah serves.

Using the smart server saves a few minutes (more if you are using a slow
machine).

I don't recommend a lightweight branch. The initial download is
something you need to do only once, and if you want to work on more than
one machine, you can clone your bzr branch from one to another without
downloading again from Savannah. Plus, most version control operations
on a lightweight branch over http are *very* slow, except perhaps
`update', which is about the same.

I decided against a lightweight branch. 
Ddon't know if it was really faster (I don't have a launchpad account),
maybe some minutes. Anyway, the crucial fact that helped me keeping up was
the care of this group :)

IIUC, Bazaar can (transparently to the user) use the smart server
protocol over an HTTP connection, assuming the HTTP server is configured
to do that.
I'd expect Launchpad's HTTP server to be configured accordingly.

PS: Last I heard, the smart server is not helpful to speed up the
initial (heavy) checkout.
