proto: Tweak documentation and names around CmdChecker.

2023-02-27T13:14:15Z

tor-proto: Rename end_received.

2023-02-17T16:56:53Z

It can now indicate _any_ cell that means we can forget about a stream.

Use CmdChecker in our stream handling code.

2023-02-17T16:52:09Z

This change makes sure that open streams and half-closed streams have the same stream-type-dependent state machines with respect to which cells are acceptable. Fixes #774. Fixes #769.

tor-proto: Add a TODO about simplifying a common pattern.

2023-02-15T15:51:03Z

tor-proto: Push stream message parsing into the stream objects.

2023-02-15T15:48:19Z

This closes #525, and ensures, at last, that we don't parse any message that we wouldn't accept.

tor-proto: Defer parsing of messages send to half-closed streams

2023-02-15T15:48:19Z

This includes a partial solution for #769, but also turned up another bug (#774) while I was working on it. I'll close them both once I have a real solution.

tor-proto: stop reactor (and kill circuit) if meta handler fails

2023-02-15T15:48:19Z

If the meta handler reports an error, then the circuit has violated its protocol, and needs to be shut down. Fixes #773.

tor-proto: defer meta-cell parsing to the last moment.

2023-02-15T15:48:19Z

tor-proto: Use UnparsedRelayCell to start deferring cell processing.

2023-02-15T15:48:19Z

In general, we want to avoid parsing these cells until we are fairly sure that they are something we would accept.

tor-cell: Refactor relay cells to copy much less

2023-02-15T15:48:19Z

We now manipulate raw relay cell bodies as (an alias for) `Box<[u8;509]>` rather than as (an alias for) `[u8;509]`. This enables us to do much less copying. It will become more important soon, as we defer parsing relay cell bodies even longer. Related to #7. We also use SliceWriter to avoid allocating a Vec<> for every relay message we want to encode, and instead encode directly into the cell.
