Unable to compile

[patrick.little@…]

My organization uses VisualSVN and it's Trac plugin to host our environment. Therefore I have to compile plugins as eggs and then install them through the web admin interface. (I do not get command access to the server.)

To match the server environment, I installed the same server programs on my machine so that I can build compatible eggs. This has worked with several other plugins, but I'm unable to get a compile to proceed.

VisualSVN includes Trac 0.12.3 and python 2.6.6

After downloading the trunk source, the command "python setup.py bdist_egg" results in:

running bdist_egg
Traceback (most recent call last):

I've seen this issue before. You are using SVN 1.7.x?

[patrick.little@…]

VisualSVN 2.5.1 runs SVN 1.7.1

[Ryan J Ollos]

Please try removing tag_svn_revision = true from setup.cfg. I think this is a known issue and I'm working on digging up previously reported information.

[Ryan J Ollos]

The issue seems to be that setuptools doesn't support SVN 1.7 metadata: #9565, #9709, ​mailing list, ​t:#10658, ​setuptools issue #79.

There seem to be some ways to workaround the issue:

• Remove the line tag_svn_revision = true form setup.cfg, or set it to tag_svn_revision = false.
• Download the zip archive and run easy_install or setup.py bdist_egg on the extracted archive rather than a working copy.
• Run easy_install tracaccountmanager to install directly from PyPI.

I haven't tested any of those methods myself, so please report back if you have success with any particular one of them.

hasienda: I suggest we close this as invalid since it's an installation issue. We could make a note about this on the AccountManagerPlugin page, but it affects all plugins and the note is unlikely to be read, so I think we just need to be mindful of the issue and continue to deal with the installation issues as they arise on the mailing list and in the issue tracker.

[patrick.little@…]

Yes, the setup completes after removing that line. I'll keep that in mind for other plugins as well.

I agree with hasienda that this issue is resolved. For those same reasons I did not want to mark this ticket as a defect or an enhancement, leaving it as the only remaining type [task].

Thank you for the quick response time :) Now to get my IT department to upgrade the environment.

[Ryan J Ollos]

One other note for future reference: from reading various resources, it appears that another valid workaround is to install the ​setuptools_subversion package.

Hm, I remember you introducing this config option. I'm fine with your suggestion, because anything apart from removing that option would not be effective in the long run. Most of the users won't RTFM, very true.

Special thanks to the OP for being that mindful to not claim a plugin defect for this issue.

I hadn't considered removing it until you mentioned now. The value of the option is that we can more easily determine the SVN revision for users that choose to install from the trunk using Subversion (SVN revision is shown in error reports, on the plugin admin panel, on the About page). However, in light of this defect, it might be worth considering to remove the option from setup.cfg. Maybe, we should keep that under consideration and see if it gets to be more of a problem as SVN 1.7 gains more widespread usage.

[patrick.little@…]

Could you instead use ​SubWCRev to determine/encode the SVN rev of the trunk the user built from?

[Ryan J Ollos]

That might work if we only had to worry about the Windows platform ;) It sounds similar to the solution proposed in ​setup tool issue #79, using the SVN client to get the query the WC metadata.

Yes, reasonable and potentially helpful. That's why I didn't complain before.

Well, I'm not married to it either, and was thinking straight and loud.

Agree.

I would like to apply the remedy 'Remove the line tag_svn_revision = true form setup.cfg, or set it to tag_svn_revision = false' for I situation where I encounter the same error when trying to install with 'sudo easy_install -Z -U ​http://trac-hacks.org/svn/xmlrpcplugin/trunk'. Where would I find or place that setup.cfg?

You'll need to checkout the source from SVN. The file is located here: xmlrpcplugin/trunk/setup.cfg​. Instructions for checkout from SVN are found here: XmlRpcPlugin#DownloadandSource. See ​trac:TracPlugins for more info on installing Trac plugins. Again, please ask on the ​trac:MailingList if you have more questions (I assume this is the same commenter as comment:11:ticket:9709 and ​SO:27032905).

Thx, now works with checkout, etc.. Indeed same commenter as comment:11:ticket:9709. Will sign up to mailing list.
