RE: Python 2.6 bindings

Mark, Daniel,

Thanks for all your inputs.
I think I am getting closer to the seeing the light at the end of the tunnel
:). I will describe below all the steps that I took in order to download,
install and setup. Please let me know if everything seems alright or I need
to change anything. I read that when I create a Trac project, it should ask
me about the repository type and repository path, which is not happening. I
was wondering if it is because of the newer version of Python (2.7).

Another dilemma that I have is related to the repositories.
From the Trac project webpage, when logged in with admin privileges, I can
create a repository by going to Adim -> Repositories -> Add repository. Here
I can create a new repository. Let's say that I'm creating Repository1. From
here it says that I should set up a post-commit hook on the repository to
call trac-admin $ENV changeset added "Repository1" $REV for each committed
changeset. I don't understand what that is and how should I do this.

Also, what do I need to install in order to be able to check in files?

Thank you so much,

- Alina.

Here are the steps that I took in order to download, install and setup.

Trac-Subversion Installation in Windows

The following software packages must be installed:
1. Python
2. setuptools
3. Genshi
4. SQLite Database
5. Subversion
6. Apache

Perform the following steps:

1. Python: Download Python 2.7.1 Windows Installer (python-2.7.1.msi)
from http://www.python.org/download/. Install it by double clicking on

2. setuptools: Downloaded setuptools
0.6c11(setuptools-0.6c11.win32-py2.7.exe (md5) ) from
http://pypi.python.org/pypi/setuptools. Install it by double clicking on

3. Add the following to the Path Environment Variables:
C:\Python27\Scripts; C:\Python27\.
4. Genshi (it comes with Python 2.7). From the command line:
> easy_install Genshi

5. SQLite Database (it comes with Python 2.7). Does not need to perform
any steps to install it.

6. Subversion, 1.5.x or 1.6.x and the corresponding Python bindings:
        a. Download and install Subversion 1.6.15 first: Win32Svn
(32-bit client) from https://sourceforge.net/projects/win32svn/
        b. Download the Python bindings: svn-win32-1.6.15_py_2.7.zip
(from http://trac.edgewall.org/wiki/TracSubversion ). Unzip and copy the two
folders under the extracted package (libsvn and svn) under
        c. Create a subversion folder:
> mkdir C:\Projects\SVN
        d. Crete SVN repository
> svnadmin create C:\Projects\SVN\TestRepository

7. Apache: Download and install win32 Binary including OpenSSL 0.9.8o
(MSI Installer): httpd-2.2.17-win32-x86-openssl-0.9.8o.msi from

8. Create a password file for Trac by using htpasswd.exe from Apache
> Cd C:\Program Files (x86)\Apache Software
> htpasswd.exe -b -c password.txt afrey dds4mo
> The file password.txt will be copied under Trac after it
will be installed.

9. Install Trac from the command line:
> easy_install Babel==0.9.5 Genshi==0.6
> easy_install Trac
> I have a step that does the install by double clicking on
Trac_0.12.1.win32.exe. I don't understand what that does, if it does the
same thing as the easy_install or not.

10. Create a project environment:
> trac-admin C:\Projects\Trac-Test initenv
> Prompted to enter the following:
> Project name: Test
> Database connection: just press <Enter> to take the default
> Noticed that it did not ask anything about subversion.

11. Copy password.txt to C:\Projects\Trac-Test\auth\ password.txt. If
the folder auth is not created yet, create it now. The file should reside
somewhere else so it does not depend on only one project (in this case

12. Start Trac from the command line:
> tracd -p 8000

13. Add user with admin priviledges:
> trac-admin C:\Projects\Trac-Test permission add afrey
> trac-admin C:\Projects\Trac-Test permission add mgilger
> To see all the users and permissions: trac-admin
C:\Projects\Trac-Test permission list

14. The environment could be configured by editing the file:

15. To add an image to the Trac project home page:
> Copy picture TestLogo.png (that was previously created and
saved somewhere on the computer) under
> Modify C:\Projects\Trac-Test\conf\trac.ini. Look for the
section [header_logo] and add or replace the following lines:
> alt = Test
> height = 70
> link = http://...
> src = site/TestLogo.png
> width = 170

16. Start the Trac project webpage:
> http://localhost:8000/Trac-Test

17. Create repository (need to be signed in with admin rights):
> Click Admin button (top of the page)
> Click Repositories button (left bottom)
> Add Repository:
> Name:Repository1
> Type: svn
> Directory: C:\Projects\SVN\TestRepository

18. Synchronize Trac with the repository
> trac-admin C:\Projects\Trac-Test\ repository resync
> What I get is:
> Resyncing repository history for Repository1...
> 0 revisions cached.
> Done.

19. ???Set up a post-commit hook on the repository to call trac-admin
$ENV changeset added "Repository1" $REV for each committed changeset.

On windows installs, there is usually a little system tray applet called
something like 'apache monitor' which will tell you. If it is not
running you can run it from the start menu apache folder. This also
makes it easy to start/stop apache.

In case you are not sure, apache is the common name for the well known
web server software provided by the apache foundation, although I
believe that strictly speaking apache 'httpd' is the web software,
apache do quite a lot of software, now including subversion of course.

You can run both trac and subversion with or without apache, both
approaches have advantages. This is an example why it helps to give
more background info about your setup when posting a question, then help
can be tailored to your needs...

You do not need apache but have a read of both the subversion red-book
docs [1] and the trac guides [2] to help you decide. If you do decide
on apache, it is a separate download and install and no, it's not
included in python.

[2] http://trac.edgewall.org/wiki/TracInstall

The *.so files are apache loadable modules that you need to get
subversion running behind apache and need to be added to your apache
config. You do not need them if you are running trac and subversion

No, sorry, I can see why you might think that. No, you just need to
copy all the .pyd files (which is just a DLL with a python-specific
extension) to *.dll but keep them in the same directory. I'm not
totally sure why this is necessary but it does not work properly if you
don't! Did you read the link I included?

> I appreciate any input. Thank you,

No problems, I hope you get it working.
