Bzr index hangs on 100% CPU

[Ian Brandt]

I tried to index a shared no-trees repository to facilitate Loggerhead's search, but it's been hanging at the following step for hours:

$ bzr index /var/lib/bzr/trunk
[##############| ] Indexing...:Saving group 3/4

CPU has been at 100% per top:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
6268 bzr 25 0 2038m 2.0g 3048 R 100 51.8 256:36.50 bzr

Here's the branch info:

$ bzr info -v /var/lib/bzr/trunk
Repository branch (format: unnamed)
Location:
  shared repository: .
  repository branch: trunk

Format:

$ bzr --version

I installed bzr-search by:

$ bzr checkout lp:bzr-search
$ cd bzr-search
$ sudo python setup.py install

Let me know if there is any more info I can provide. I'm going to kill the process for now.

How big are individual trees in the repository?

Forgive my ignorance with the terminology, but as it's a "treeless shared repository" as I understood it from the docs let me just give you a bunch of sizes in the hopes that one of them is what you mean:

treeless shared repo '/var/lib/bzr/trunk': 20MB
treeless shared repo '/var/lib/bzr/.bzr/': 690MB
checkout of trunk '.bzr/': 666MB
checkout of trunk everything else: 179MB

Sorry for not getting back to you more quickly. I suspect you're running into a issue with bzr's B+Tree indices that was fixed between 2.0.0 and 2.1.0 - updating to a 2.1.0rc should fix this for you.

Please let us know how that goes.
