I'm trying to learn how to parse SANs in C thanks to the source code of curl https://github.com/curl/curl/blob/935e1f9963a12ac1a880df538b23b824d2fea7bb/lib/vtls/openssl.c#L2073
Why? I would like pgBackRest to parse SANs before CN because CNs are deprecated for years and they are optional.
The problem is that no matter how hard I try to learn and write C, I fail.
I tried to implement Proxy Protocol for PGbouncer and PostgreSQL, failed.
I could open an issue, wait for a fix and cross my fingers or pray the gods, but I don't want to overload the project. My issue is not that important. What's important to me is the personal reward of contributing to open source. I want to learn. I want to contribute. I want to be a little part of the movement.
You should ask Claude they say. It will be fun they say. I'm not ready for that. I don't want to bypass everything for one of my side projects. But in the meantime, I'm frustated of failing. This is very tempting I must admit.
