If you have multiple, unrelated projects, is it a good idea to put them in the same repository?
myRepo/projectA/trunk
myRepo/projectA/tags
myRepo/projectA/branches
myRepo/projectB/trunk
myRepo/projectB/tags
myRepo/projectB/branches
or would you create new repositories for each?
myRepoA/trunk
myRepoA/tags
myRepoA/branches
myRepoB/trunk
myRepoB/tags
myRepoB/branches
What are the pros and cons of each? All that I can currently think of is that you get mixed revision numbers (so what?), and that you can't use svn:externals unless the repository is actually external. (i think?)
The reason I ask is because I'm considering consolidating my multiple repos into one, since my SVN host has started charging per repo.
one additional thing to consider is the fact that using multiple repositories cause you to loose the ability to have unified logging(svn log command) this alone will be good reason for choosing single repository.
I use TortuiseSvn and found that the "Show Log" option is a mandatory tool. although your projects are unrelated, I'm sure that you will find that having a centralized global cross-projects information (paths, bug ids, messages and so on....) is always useful.
