Turned out that the bug ocurred randomly. The first tries I just had the “luck” that it only happened when the breakpoints were on.
Fixed it by now btw.
I’m new to Go and wanted to copy some text-data from a stream into the outputstream of the HTTP response.
I was copying the data to and from a []byte with a single Read() and Write() call and expexted everything to be copied as the buffer is always the size of the while data.
Turns out Read() sometimes fills the whole buffer and sometimes don’t.
Now I’m using io.Copy().
Aren’t those almost always race condition bugs? The debugger slows execution, so the bug won’t appear when debugging.

someone’s not sharing the actual root cause.
