Couldn't reproduce locally.

Feel free to reopen after getting concrete reproduction steps.

@autozimu I think the issue here is that the textDocument/didOpen method is not triggered until the file is edited in some way. I am experiencing the same behaviour as @mcepl, but when I trigger insert mode I can see messages in the server log like:

2018-03-01 09:20:35,940 UTC - DEBUG - pyls.server - Got message: b'{"jsonrpc":"2.0","method":"textDocument/didOpen"
...

I think the issue originally reported in palantir/python-language-server#263 is showing an error where the file isn't stored in the cache, and this is only triggered once the file is "edited" in some way.
