Bitten & Trac 0.12

[anonymous]

Hi, I have got an issue with Bitten (from SVN Bitten 0.6dev) & Trac 0.12. Bitten is installed and when I try to add a Build Configuration in the admin panel, I have got the following error :

Trac detected an internal error:

AttributeError: 'NoneType' object has no attribute 'get_node'

The AttributeError I suppose is much of the same discussed in #342 - get_node() is a repository method. Bitten won't target Trac 0.12 with upcoming 0.6 release, so just rescheduling it slightly.

Are you using 0.12 'plain', or multirepos?

[hugobosscool26@…]

I have tested both versions in fact and I have the same error.

[jhampton]

Are you using SVN as the repository backend? or some other repository type?

[jhampton]

yeah, I'm brilliant and managed to mess up my username when adding it to the CC list.

Dont' mind me, just fixing the CC list

[hugobosscool26]

:) SVN Repositories yes.

[piotr@…]

Same issue coming up again. This time Bitten 0.7dev_r811 and Trac 0.12dev_r9184. If there's any resolution, forgive me, but I cannot find it.

Hi,

Can you fix this defect?

when use multirepos, and create new Build Configuration, trac wrote:

AttributeError: 'NoneType' object has no attribute 'get_node'.

Trac 0.12dev-r9593 Bitten 0.7dev-r870 Subversion 1.6.11 (r934486) mod_python 3.3.2-dev-20080819

Replying to anonymous:

Can you fix this defect?

If only it was a small defect/bug... The fact is that Trac 0.12 is not currently supported, as the multi-repos merge made drastic changes to the internal repository and change handling that Bitten uses. Bitten 0.6 does not support Trac 0.12, and currently that work is likely to be targeted for a future 0.7. There are various stray patches like on #342, but currently nothing committed to repository.

[Steven R. Loomis <srl@…>]

FYI: Almost all of my patches against bitten r881 for trac0.12. (I am using this in production- cue scary music) - works around missing authz and fixes an earlier issue with timeline. Doesn't support multi-repos at all, other tickets for that.

[Steven R. Loomis <srl@…>]

My patch is against bitten trunk, forgot to mention that.

[osimons]

This latest patch on this ticket is identical to the patch cooking over at #480. Some issues with it are already reported there but not yet fixed - particularly for proper configuration on fresh 0.12 projects.

I propose we keep #480 as the ticket for doing 0.6-targeted Trac 0.12 support, which in reality means only "default repository" as defined in config using 0.11-style repository configuration.

This ticket should target the longer-term support for actually fully supporting the new multi-repository model in Trac 0.12 that may ckeckout, build and report across multiple repository backends and paths configured in a single Trac project. The mentioned 342 contains some patches towards this end.

[Myroslav Opyr <myroslav@…>]

FYI, there's multipath patch "in-the-wild" attached to #244. Maybe multipath code can be starting point for multi-repos support?

[osimons]

Following [1016] I think this ticket should be closed. We keep #342 for tracking the problem of dvcs branches, but otherwise the main multi-repository support for Trac 0.12+ should be concluded now that #765 is fixed.
