pyls crashes after invalid path exception on Windows

See original GitHub issue

I am evaluating the new LSP package for Sublime Text 3 together with python-language-server at the moment.

Sublime Text freezes frequently with LSP connected to pyls, which is discussed in https://github.com/tomv564/LSP/issues/12

After some investigation I found a crash of pyls to cause LSP to hang while reading from stdout/stderr, which might be the reason for the troubles.

I configured pyls to write a logfile instead of writing errors to stderr, which seems to prevent ST from freezing so far. The log shows following errors at some point.

It looks like pyls to not translate the file uri correctly at some point, which causes invalid path exceptions on file evaluation. I haven’t located the issue nor did I try to fix it yet, so I am not quite sure whether it is an issue caused by LSP or pyls. As LSP sends an uri like file://C:/... I consider pyls to not translate the file path correctly.

You shouldn’t assume “file” is the scheme of the URI

From: deathaxe notifications@github.com Sent: Friday, August 18, 2017 4:34:51 PM To: palantir/python-language-server Cc: Nicholas Gates; Comment Subject: Re: [palantir/python-language-server] pyls crashes after invalid path exception on Windows (#94)

Yep, the unquote(urlparse(uri)) constructs result in /C:/Apps/… path instead of C:\Apps.. which causes jedi to add another C:\ to the path as it interprets the leading slash as relative path.

I was able to fix the issue by using the following function from LSP package as replacement for unquote(urlparse(uri)) in workspace.py

def uri_to_filename(uri: str) -> str: if os.name == ‘nt’: path = url2pathname(uri.replace(“file://”, “”)) else: path = url2pathname(uri).replace(“file://”, “”) # debug(uri, path) return path
