Some errors on mac os

k-bx opened this issue 10 years ago · 8 comments

Hey! So I just wrote small script like this:

{-# LANGUAGE OverloadedStrings #-}
{-# LANGUAGE QuasiQuotes       #-}

import           FileCommand
import           Twitch

main :: IO ()
main = defaultMain $ do
  "*.jsx" |> [s|make static|]

Upon launch it waits for some time, and then throws bunch of output at me:

Answer 1 · 2014-12-24T00:41:04.000Z

I did some research, and this is an issue that effects many watchers on OSX.

From what I can gather, there is an error early in initialization that is not propagated, and later the watchers fail because they are in a bad state. I will see if I can rework the use of FSNotify to get around this, otherwise I will file an issue with their repo.

Sometimes restarting fixes it. The real fix is to fail earlier and display a more informative error message.

Now there is something else that could be going on. Are you running in non-threaded mode? You only get 1024 file handles in non-threaded mode which could explain this message:

WatchStatic: <file descriptor: 1024>: hGetBuf: invalid argument (Invalid argument)

Also how many files are in that directory? Are you running this with ghci or are you building an exe?

Answer 2 · 2014-12-24T07:23:28.000Z

I'm building an exe. You were right, I forgot to put "ghc options" for this new executable, so it wasn't in threading and even wasn't optimized. Will add and check now.

No, still gives:

Problem is consistent on every start.

There are 8890 files in project directory 4 of them are under glob pattern I used.

I will do a bit of debugging today, as you mentioned "getting better error-message is a real fix".

Thanks for the input :)

Answer 3 · 2014-12-24T07:24:37.000Z

Btw, after 2 or 3 seconds it says "Type anything to quit" and quits.

Answer 4 · 2014-12-24T07:53:32.000Z

Btw, running as:

./dist/build/WatchStatic/WatchStatic --directories "[\"./resources\"]"

helped to not get errors, but at the same time it doesn't do anything upon file created in that resources path. Fullpath didn't help.

Answer 5 · 2014-12-24T08:05:24.000Z

Ha! Interesting. So it turns out twitch works after all (without that --directories being passed). Touching some jsx file did run the command.

So, now I'm only confused:

why that --directories option didn't work (it doesn't produce that many errors, but also doesn't listen to new files)
can we make it more user-friendly to pass :)

This might be separate issue.

Answer 6 · 2014-12-24T10:46:19.000Z

After debugging I see the reason why --directories doesn't work as I want it to. Even when --directories is passed, Twitch.Rule.compilePattern still compiles pattern to /Users/kb/workspace/twitchtest/*.jsx, not /Users/kb/workspace/twitchtest/resources/*.jsx as I would expect. But at least I know how to fix it -- I should make a pattern **/*.jsx and everything works!

Answer 7 · 2014-12-28T21:47:58.000Z

I presume errors would still happen on big directories, so maybe it's too early to close this one. Thanks for fixing others anyway, will definitely use those!

Answer 8 · 2014-12-29T00:37:50.000Z

Fair enough, reopening to make it easier for others to find your workaround.
