http_server crashes immediately
keith opened this issue · comments
I'm attempting to test this out on our Swift project. I've generated a compile_commands.json, and followed the installation instructions using the branch from the readme. Then when I attempt to fetch completions the first time, http_server crashes with this log:

Please let me know if there's any more info I can provide here to help debug.
Hey @keith - thanks so much for the bug report 🚀
I looked into your stack trace this afternoon, and I was able to reproduce a similar callstack as you in a few conditions. #9 fixed similar crashes for me, Now, it handles odd behavior and empty responses so the client to continue to work. I hope this fixes it for you!
If this doesn't address it for you, I'd be helpful to see the server logs. In YCM, you can access this in the debug UI by running the commnad :YcmDebugInfo and dumping the SwiftySwiftVim's logs ( SwiftySwiftVim logfiles: ) in the debug UI. These should make it easier to understand exactly what lead to the crash happened in either the server and SourceKit. I think that should be good ( otherwise, I can try to repro with a test project and comb db )
From my testing, the server was failing when SourceKit gets into weird states and crashed internally. I think these cases will need some client work in the future to make it 100% perfect - I'm currently working on a new client and will address it there soon.
PS: if you're on YCMD you can try #9 by going into YouCompleteMe/third_party/ycmd/third_party/swiftyswiftvim/ pulling the branch, and running bootstrap 👍
