Introduces shared memory capabilities #116

Closed jakaplan closed 2 years ago

jakaplan commented 2 years ago

The SharedTrivial property wrapper conforms to Codable but is not serializing its boxed value, it's actually mapping it into shared memory which can be accessed and modified across processes.

Note - I didn't write any tests for this because they unfortunately don't seem very useful as our tests all run in the same process. I could write some very basic ones, but they're not going to catch actual cross-process issues. I did test this a fair bit using an app with an XPC service.

@amomchilov Would appreciate your eyes on this if you have time. Shared memory is not an area I'm an expert in, so definitely possible I got something wrong here.

Heads up my intention is to follow this up with a to-be-written PR for a collection like class (think a fixed capacity array of trivial types) and also potentially a fixed capacity Data like class.

@amomchilov If you do end up seeing this PR, don't bother looking at it - just skip to https://github.com/trilemma-dev/SecureXPC/pull/119 instead.
