bzr branch leads to out of memory

[Hakan Küçükyılmaz]

How to reproduce with bzr 2.0.2

bzr init-repo /tmp
Shared repository with trees (format: 2a)

This ends with OOM:

time bzr branch lp:maria maria-local-master
You have not informed bzr of your Launchpad ID, and you must do this to
write to Launchpad or access private data. See "bzr help launchpad-login".

real 616m23.099s
user 421m24.961s

Please note the ~1.5GB repository size. Actually lp:maria is about 600MB

I tried to branch with bzr 2.0.1 and 2.0.2 on CentOS 5.4, OpenSUSE 11.1, Ubuntu 9.04 on 32-bit and 64-bit machines.

This is a duplicate of bug #456077.

lp:maria uses the 1.9 or 1.14 format, while your new repo uses 2a. Converting on the fly over the network is...not efficient. You should make your local repo 1.9 or 1.14, branch lp:maria, then "bzr upgrade --2a" if you want to upgrade it.

(Or use my 2a branches and save yourself the trouble. ;-)

Also, I'd like to point out that just because bzr has transferred ~1.5 GB of data, that doesn't mean either the source or destination repo is actually that large. It's possible bzr is just being inefficient. :)
