[BUG] Debug messages are printed to log

[jbarlowbignell]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The code has started printing debug messages to via log.Printf(). For example:

2023/09/19 09:27:23 websocket: discarding reader close error: io: read/write on closed pipe

It seems to have been introduced recently:

Expected Behavior

No debug messages are printed to the console.

Steps To Reproduce

No response

Anything else?

From the pull request notes, it seems like there were comments saying that writing to the application's stderr is unfriendly. I agree...

Is there a way to get rid of those log messages?
If it is not possible, how could I check if connection is closed before to call ReadMessage?
