I've followed the instructions on https://prosody.im/doc/developers/http#serving_files to serve static files from a module. However, it doesn't work, even with the example given on that page.
The first problem is that it throws an exception:
http.server error Traceback[httpserver]: ...ody/0.9/build/lib/prosody/modules/mod_http_files.lua:62: attempt to index local 'path' (a nil value)
stack traceback:
...ody/0.9/build/lib/prosody/modules/mod_http_files.lua:62: in function 'sanitize_path'
...ody/0.9/build/lib/prosody/modules/mod_http_files.lua:92: in function '?'

This seems to be due to serve_file receiving different arguments than it expects. I managed to fix this with https://code.xnyhps.nl/prosody/0.9/rev/92f892811d2b.
The second problem is that when the path isn't a wildcard, it resolves the full path rather strangely. With the example from the wiki, it tries to read the file:
/Users/thijs/Projects/Prosody/0.9/build/lib/prosody/modules/my_file.txt//mymodule/a_file.txt
This is not what I expect, I expected it to look for just:
/Users/thijs/Projects/Prosody/0.9/build/lib/prosody/modules/my_file.txt
Reading the rest of the code, the commit is probably wrong because it causes the second problem. I don't really understand how the directory listing code is supposed to work, so I can't propose a correct patch.

This looks like a regression from #520.
ChangesThe code originally allowed for the path argument to be empty, it then used the entire configured path from the serve() call.
ChangesOT: Where did this empty tag come from?
ChangesFixed in http://hg.prosody.im/0.9/rev/b5b7ae2901e6 Testing appreciated
