Installing the XMLRPC plugin on DreamHost (virtual python environment)

[Kamil Libich]

Hi,

The Scenario:

Trac version 11.4

The aim: to connect to the trac from iPad thru tracViewer app.

The tool: the XMLRPC trac plugin has to be installed on the server side.

The problem: how to install the XMLRPC on the server.

The things done:

1. virtual python environment has been installed succesfully (in $HOME/env)

The show stopper: the variable $PYTHONPATH. To what it shall be set to?

The unknown: how this virtual python environment works and what I shall to do to install the plugin

The error message of the showstopper:

=================================================================================

[BAT]$ which easy_install

/usr/bin/easy_install

[BAT]$ source env/bin/activate

(env)[terranova]$ which easy_install

/home/kik/env/bin/easy_install

(env)[BAT]$ easy_install --install-dir=$PYTHONPATH http://trac-hacks.org/svn/xmlrpcplugin 0.10 # 0.10

TEST FAILED:  does NOT support .pth files

error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not

on PYTHONPATH and which Python does not read ".pth" files from.  The

installation directory you specified (via --install-dir, --prefix, or

the distutils default setting) was:

and your PYTHONPATH environment variable currently contains:

    ''

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is

  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment

  variable.  (It must then also be on PYTHONPATH whenever you run

  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by

  using one of the approaches described here:

  http://peak.telecommunity.com/EasyInstall.html#custom-installation-locations

Please make the appropriate changes for your system and try again.

=======================================================================================

Please help.

You want the 0.11 (= trunk) version for Trac 0.11.4 (for anything 0.11+). The version for Trac 0.10.x will no longer work for your more recent version. It should look something like:

(env)[BAT]$ easy_install http://trac-hacks.org/svn/xmlrpcplugin/trunk

...which is the URL copied from the plugin documentation that you don't seem to be following? Check this:

Thanks Simon,

Maybe really this is a part of the problem. However, I think the main problem is on the PYTHON/PYTHON virtual environment border.

The installation command I'm issuing comes from my hosting company:  
http://wiki.dreamhost.com/Trac#Plugins 

http://wiki.dreamhost.com/Python

However they are not supporting neither the trac nor Python, so I don't have the support of them.

My questions:

1. What is that PYTHONPATH variable? To which value it has to be switch set?

2. What is that source /path/to/env/bin/activate command for?

3. If I install this in my Python/Trac environment will the plugin be available to all my trac sites automatically?

4. Where to observe the log if any?

Cheers,

Kamil

If you have virtualenv installed, and have activated it (either by "activate" or by running configured scripts directly like "/path/to/env/bin/easy_install") all environment settings should be prepared for you. You should just use the defaults for the virtualenv and don't need additional paths, so really just ignore it. The modules you install for the virtualenv will end up in /path/to/env/lib/python2.x/site-packages/ which is just fine, and don't use additional configuration or command-line switches when installing.
 

2. What is that source /path/to/env/bin/activate command for?

See 1. It basically switches your shell to environment variables prepared for the virtualenv you activate. So that you run the correct scripts, install to correct locations etc. You may want to read through the virtualenv docs and make sure you understand what virtualenv is (and isn't): http://pypi.python.org/pypi/virtualenv
 

3. If I install this in my Python/Trac environment will the plugin be available to all my trac sites automatically?

Yes, it will be a "global" install - for all trac processes that originate in that virtualenv. Need to be enabled in each project.
 

4. Where to observe the log if any?

Ok, bit of log I get when I want to connect from tracViewer.

I installed the plugin according to instructions in trac-hacks. I don't have the 'problem' with the PYTHONPATH any more

I modified trac.ini file with components section.

Anything obvious?

Yes. The most obvious is that the log does not contain anything related to RPC. If you can make a request to /rpc and the RPC plugin is working, I suppose your problem may be related to the ios app rather than Trac and RPC plugin. Does a /rpc (or /login/rpc) web request return a nice overview of the RPC documentation?

I don't know the TracViewer app, and without any useful error information there is not much more I can do to help.

Have you tried the TracViewer support contacts?
