Signatures unusably slow on large codebase

[eevee]

I tried jedi at $work today and the cursor movement was so ridiculously laggy that I could barely write any code. Some hamfisted profiling revealed that show_call_signatures was blocking vim for almost half a second for every keypress in Insert mode.

Obviously I'm turning this feature off :) This was a decently-sized file (1000 lines?) with lots of imports (dozens) in a very large codebase (millions of lines?), but there looks to be clear room for improvement here:

• I get the delay even when the cursor isn't inside a function call, where it ought to be pretty easy to notice that nothing needs doing.
• From a quick glance, I think jedi is reparsing the entire file every time I add a character? Surely if it already has an AST for a pristine file and the only change I've made is to type a w on a new line, it can make some use of the information it already had?

Duplicate of #217.

Please update to Jedi 0.8.1. 0.8.0 was buggy in that it always reparsed the file (well or at least parts of it). There's still room for improvement. But the bigger issue is, that it's very hard to do async in VIM. :)

show_call_signatures is now way faster. For a multitude of reasons. Jedi has been rewritten.
