1.14rc2 and CHK: Random 'AbsentContentFactory' object has no attribute 'get_bytes_as' errors

Thu Apr 23 09:19:54 BST 2009

Hi all,

I'm doing some work on a private project, and I chose to test drive the
--development6 format with that. While hacking, I encountered twice the
error "'AbsentContentFactory' object has no attribute 'get_bytes_as'"
(full log at the bottom of this message), on two different branches on
two different machines.

The first time I was committing again a change I had just uncommitted in
order to fix a typo in the message. The second time I was pushing a
branch to my home server and the error came from the bzr smartserver.

In both cases, the branch is inside a shared repository created with
bzr init-repo --development6 (for the second case, both the local and
remote branches are).

In both cases, the problem was solved by running bzr pack. The first
time I did this, I run bzr check before and after the bzr pack and got
exactly the same output (not included here as the log is on my laptop,
but will post it if you think it's useful).

I tried to replicate the problem before reporting, but couldn't.

Here follows the .bzr.log from the second event (i.e. pushing to
remote). The log also includes the following bzr pack and successful
bzr push.

Regards,
Tommaso
