• Simon Ser: Status update, March 2023

  Hi all!

  In the past week or so I’ve focused on a NPotM: go-imap, an IMAP library for Go. “But Simon, a New Project of the Month is supposed to be new!” Right, right, the NPotM is a lie… But only a half-lie: I’m rewriting it from scratch. go-imap was one of the first Go projects I’ve written, and I couldn’t recite the IMAP4rev1 RFC by heart at the time. This is just a roundabout way to say that mistakes were made. IMAP extensions — a lot of which provide important functionality — were designed to be implemented out-of-tree in separate Go modules. However many extensions change the behavior of existing commands, so trying to design a modular system is a fool’s errand which only results in a more complicated API. Go channels were (ab)overused in the public API. The internals were not designed with goroutine safety in mind, so races were ducktaped after the fact. It’s not possible to run multiple IMAP commands concurrently: each time a command is sent, the caller gets to twiddle their thumbs until the reply comes back before sending a new one, paying the full price of the roundtrip. The parser has a weird intermediate representation based on interface{} Go values. Many functions and types are exported in the public API but really shouldn’t be.
