This hack is a simple patch that lets you have a Trac environment parent directory under another Trac environment in a directory called 'projects'. The subprojects are then accessible via the URL of the parent project slash 'p' slash sub project name. For example: /parentproject/p/childproject
It only works when using an environment parent directory for the top level afaik. Hopefully this is useful for somebody.
If you have any issues, create a new ticket.
Download and Source
Apply the patch to trac/web/main.py. Create an environment called 'foo'. Create a directory in 'foo' called 'projects'. Create another environment inside 'projects' called 'bar'. Start tracd and point the env-parent-dir to the parent of 'foo'.
You should now be able to go to both /foo and see project foo, and go to /foo/p/bar and see project bar, with valid URL generation and everything.
and then i had to remove some stuff the mercurial diff put in there.
this corrects a problem in that last revision where the patch came from a version that was incorrectly patched from before. follow? it works now... actually tested
updated patch for latest 0.11
