[Buildbot-devel] pyasn1-0.1.1 seems to break manhole on new install

[Maarten Verwijs]

I posted the following on trac, but got tagged as spam. Here's a second
go: 


On november 6th there was a new version of pyasn1 released on
http://pypi.python.org/packages/2.6/p/pyasn1/. 

Using this version breaks the import of manhole when doing a new
installation of a master.

Installing the previous version using pip, all works fine. 

== Solution ==

(Workaround really):

{{{
pip install pyasn1==0.0.13b
}}}

Preferably the tutorial should reflect this.

== Versions ==

* Buildbot 0.8.5
* pyasn1 0.1.1
* Debian 6 AMD64


== Reproduce ==

* Follow the official Buildbot tutorial
* (http://buildbot.net/buildbot/docs/0.8.5/tutorial/firstrun.html)
* When importing manhole from buildbot, start or reconfig will fail. 
* Downgrading pyasn1 to 0.0.13b or earlier fixes it.

The startup log using pyasn1-0.1.1:

The buildmaster took more than 10 seconds to start, so we were unable to
confirm that it started correctly. Please 'tail twistd.log' and look for
a
line that says 'configuration update complete' to verify correct
startup.
