DAP: Support the startDebugging reverse request (#13403) 2025-06-23 09:48:05 -05:00
Michael Davis 8d2870b94a
Reuse content buffer in JSONRPC recv for LSP and DAP 
Previously `recv` for new messages from the language server or debug
adapter allocated a fresh Vec for each message. Instead we can reuse
the buffer. This resolves TODO comments.

DAP: Drain pending requests on recv failure 
This matches <https://redirect.github.com/helix-editor/helix/pull/4852>
for the DAP transport: when there is a failure to receive a message from
the debugger we should drain all pending requests and respond to them
with the StreamClosed error.

This improves the behavior when a debugger fails to initialize, for
example starting debugpy without debugpy installed. Previously the UI
would freeze until the request timed out. Now it instantly prints a
statusline error saying that the debugger failed to start up.

DAP: Refactor handling of Event and Request protocol types 
This change refactors the DAP `Event` type, the `helix_dap` module and
the `helix_dap::transport` module to be closer to the equivalent
implementations in `helix_lsp`. The DAP `Event` type is similar to LSP's
`Notification` so this change rewrites the enum as a trait which is
implemented by empty types (for example `enum Initialized {}`).

`Event` is then reintroduced as an enum in `helix_dap` with a helper
function to convert from the `Event` as the transport knows it. By
separating the definitions of `Event` between lib and transport, we can
handle incoming events which are not known to our `Event` enum. For
example debugpy sends `"debugpySockets"` which is unknown. With this
change, unknown events are discarded with an info-level log message.

The `Request` type was already a trait but did not have an enum with the
known values. This change also introduces a `helix_dap::Request` enum
similar to `helix_dap::Event`. This resolves a TODO comment about
avoiding `unwrap` when parsing the request's arguments.
