did you mean write TestGzipHandlerStream instead of TestGzipHnalderStream

Woops yep! Also I’m not confident in the fix but the test case reproduces the issue at hand.
Startgzip gets called but not init then subsequently startPlain gets called and then errors

This seems to introduce another issue found in the failing test case due to the reason previously mentioned. This is preventing w.init() from being called. Also, the following conditional check len(w.buf) >= w.minSize is already made in the write function.

I removed the invalid fix, but left the test case up there showing the issue we are running into |

Fix bug where writing and flushing a zero byte write would cause startGzip() to run but not write, and then on subsequent writes call startPlain, resulting in invalid header errors
