| 9 At work, we are outfitted with Windows servers. Despite this obstacle, I managed | |
| 10 to install Trac_ and Subversion_ a few years ago. During a break in the action, | |
| 11 we decided to update Subversion (SVN) and Trac. Since we are on Windows, this | |
| 12 means we have to rely on the `kindness of strangers`_ for Subversion binaries. I | |
| 13 ran into a couple of gotchas I'd like to document here to help anyone else who | |
| 14 runs into these. | |
| 15 | |
| 16 I managed to get Subversion and Trac up and running without any real problems. | |
| 17 However when Trac needed to access SVN to display changesets or a timeline, for | |
| 18 example, I got an error: | |
| 19 | |
| 20 ``tracerror: unsupported version control system "svn" no module named _fs`` | |
| 21 | |
| 22 After some googling, I finally found that this issue is `documented on the Trac | |
| 23 wiki`_, but it was kind of hard to find. To fix this problem, you have to rename | |
| 24 the Python SVN binding's DLLs to ``*.pyd``. Specifically, change the | |
| 25 ``libsvn/*.dll`` files to ``libsvn/*.pyd``, but don't change the name of | |
| 26 ``libsvn_swig_py-1.dll``. I'd really like to hear an explanation of why one | |
| 27 needs to do this. Why doesn't the Python-Windows build process do this for you? | |
| 28 | |
| 29 The second problem I ran into dealt with mod_wsgi_ on Windows. Originally, a few | |
| 30 years ago, I setup Trac to run under mod_python_. mod_python has long been | |
| 31 out of favor, so I decided to cut over to mod_wsgi. On my Linux boxes, I always | |
| 32 run mod_wsgi in daemon mode. When I tried to configure this on Windows, Apache | |
| 33 complained about an unknown directive ``WSGIDaemonProcess``. It turns out that | |
| 34 `this mode is not supported on Windows`_. You'll have to use the embedded mode on | |
| 35 Windows. | |
