Subversion sub-repository

Question

Is there any stable method of having a repo maintained by SVN as a subset of another.

I might have the following:

1. phpCodeRepo
2. pyCodeRepo
3. contentRepo

Such that 1 and 2 can have, as an element of their repo, some data of repo 3. Such that updating 3 would cause an (optional) version increment in 1 and 2. And checking out 1 or 2 will also checkout the right version of 3.

Answer 1

That's pretty simple: Add 3 folders to your root repository (phpCodeRepo, pyCodeRepo, contentRepo). You might want to look into branching, too.

Answer 2

You may want to implement using hooks

Also, you can pull in other repos when you check out using externals

Answer 3

svn:externals might be an answer. But it works only on folder level, so you can share one folder across multiple repositories but you can't do that with single files.
