[tahoe-dev] How do I do an immutable tree upload?

[Kevin Reid]

I want to experiment with running a webapp off a Tahoe grid. It would handle its own "database" read/write, but I need to bootstrap same-origin by uploading its source files to the grid.

It seems to me that the right thing here is a command which will upload the entire file tree (preferably with exclusions) immutably (to minimize duplication when I upload with changes) and return a dircap for it. What 'tahoe' arguments will do this?

'tahoe cp' requires a target directory and does not appear to produce immutable directories. 'tahoe put' does not appear to do directories. 'tahoe backup' requires a target directory and keeps old versions.

I suppose 'tahoe cp' is the closest in function I have found, but all else being equal I would like to have my 'install' function not actually use any of the user's pre-existing Tahoe capabilities. I could 'tahoe mkdir' a fresh directory and cp into it.

Any suggestions on how to do this more cleanly?
