Syntax error reporting hangs in a big projects

[istocniks]

I have a big Erlang project opened in IDEA 14.1.1 (~1000 erl modules, 500k lines of code), Erlang 0.5.11.
Sometimes syntax errors highlighting hangs and I need to wait for quite some time for errors to disappear. Usually it's related to number of function arguments. Pictures will better explain my issue:

Here you can see that function check_contact/4 is defined, but error shows that it's not.
The error I showed above is there for at least 20 minutes already and my laptop cooler spins like crazy.

Please, share a CPU profiling snapshot for this problem as well (https://intellij-support.jetbrains.com/entries/29983118-Reporting-performance-problems)

I didn't wait for error to go away

Probably related issue, that's what I see in my IDE for about an hour already

I see this also, in a reasonable sized project the syntax error reporting is too slow to be useful to the point where you need to need to pause and wait for the IDE to catch up :-(

@istocniks, thank you for sharing your snapshot - it helped a lot.

Please try out the latest build and let me know if it got better. And also attach a performance snapshot, if it's still slow.

The latest build is available here: https://github.com/ignatov/intellij-erlang/releases/

@deadok22 thanks, it seems like it's much faster now, but I can still see some stuck errors sometimes, they clear after a ~5-60 seconds though

Please, share a new snapshot so that we can see what is to be optimized.

@istocniks would you check if it's better now? Share a new snapshot, please.

I did upload a new snapshot the next day you asked for it here #610 :)

Oh, it is there. I'm sorry then =)

I was browsing through commits to figure what's to be included in release notes, and there were commits referencing this issue, which is still open.
