2024-07-16libstore: remove WriteConn::sink fieldseldritch horrors
we no longer need these since we're no longer using sinks to serialize things. Change-Id: Iffb1a3eab33c83f611c88fa4e8beaa8d5ffa079b
2024-07-16libstore: generatorize protocol serializerseldritch horrors
this is cursed. deeply and profoundly cursed. under NO CIRCUMSTANCES must protocol serializer helpers be applied to temporaries! doing so will inevitably cause dangling references and cause the entire thing to crash. we need to do this even so to get rid of boost coroutines, and likewise to encapsulate the serializers we suffer today at least a little bit to allow a gradual migration to an actual IPC protocol. (this isn't a problem that's unique to generators. c++ coroutines in general cannot safely take references to arbitrary temporaries since c++ does not have a lifetime system that can make this safe. -sigh-) Change-Id: I2921ba451e04d86798752d140885d3c5cc08e146

2023-06-19Create `worker_proto::{Read,Write}Conn`John Ericson
Pass this around instead of `Source &` and `Sink &` directly. This will give us something to put the protocol version on once the time comes. To do this ergonomically, we need to expose `RemoteStore::Connection`, so do that too. Give it some more API docs while we are at it.
2023-06-19Put worker protocol items inside a `WorkerProto` structJohn Ericson
See API docs on that struct for why. The pasing as as template argument doesn't yet happen in that commit, but will instead happen in later commit. Also make `WorkerOp` (now `Op`) and enum struct. This led us to catch that two operations were not handled! Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>
2023-06-19Split out worker protocol template definitions from declarationsJohn Ericson
This is generally a fine practice: Putting implementations in headers makes them harder to read and slows compilation. Unfortunately it is necessary for templates, but we can ameliorate that by putting them in a separate header. Only files which need to instantiate those templates will need to include the header with the implementation; the rest can just include the declaration. This is now documenting in the contributing guide. Also, it just happens that these polymorphic serializers are the protocol agnostic ones. (Worker and serve protocol have the same logic for these container types.) This means by doing this general template cleanup, we are also getting a head start on better indicating which code is protocol-specific and which code is shared between protocols.
