The arc server does not support file hierarchies yet.

Is it specifically disallowing this? Otherwise, I would think it would be transparent for the most part.

Yes, it rejects any path with a slash. I assume this is partially for security reasons (/../../../../../etc/passwd)

I can see rejecting .. to disallow access above the tree, but rejecting / doesn't make any sense to me. So we have to just plop everything down in one directory? If so, that's ridiculous. I think I need to be less critical of the forkers.

Hehehehe. It's not that we're deliberately forking off - it's more that:

1. pg has been talking about this language for years

2. he has built up a big fan club

3. he released arc in a "not-quite-done" state and unleashed a firestorm of third-party fixes

4. he hasn't updated arc again for more than a month or so.

So yes, although we're not deliberately forking off, I fear this is just what will happen unless pg updates us all again within the next few months, or puts major parts of Anarki in Arc3.

Yeah, I guess it's a case of "I'm the leader, which way did they go?" :)

I completely agree.

The code that rejects slashes is in srv.arc: gifname and static-filetype. So static files with slashes are rejected.

Hmm, it appears that Anarki doesn't disallow ../ - I'll see if this is a problem and if I can fix this later.

Fixed and on the git.

Within Anarki all the file serving was done out of the special docroot directory (at least it was a month ago). I'm not sure if disallowing "../" is what we want or if it what we really want is to ensure that all file serving comes from that dir.

Thoughts?

Disallowing .. is the easiest solution. Of course, the current solution simply rejects on any ".." including /foo..html and /subdirectory/../foo.html

Hmm probably do something with the Anarki-specific qualified-path instead...

Edit: done and on the git. Assuming you have a directory foo/ on your public_html, you can access favicon.ico by /foo/../favicon.ico

Edit: soft links would probably break though. Edit2: they don't, at least on mzscheme 360 and ubuntu

On Anarki, my images loaded in such a fashion work just fine.

So the arc server on Anarki has been modified to support file hierarchies?
