🔴 Outer mutex held during blocking recv() causes deadlock when sending commands

The event loop in app.rs:44 acquires the outer Arc<Mutex<GatewayClient>> lock and then calls client_guard.recv().await, which blocks indefinitely waiting for the next server event while holding the outer lock. When the user submits a message (app.rs:66), on_submit tries to acquire the same outer lock to call chat(), but it is blocked because the event loop holds it. Since the server won't send events until a client message arrives, this creates a deadlock: the event loop waits for a server event, the submit handler waits for the lock, and the server waits for a client message. The send() and recv() methods on GatewayClient use independent internal channels (cmd_tx vs event_rx) and don't need the outer mutex — the fix would be to either split the client into separate sender/receiver handles or remove the outer Mutex.

Prompt for agents

The root cause is that GatewayClient is wrapped in Arc<Mutex<...>> (app.rs:19), but the event loop holds this mutex lock during the blocking recv() call (app.rs:44-45), preventing on_submit (app.rs:66) from acquiring it to send commands.

Fix approach: Refactor GatewayClient so that send() and recv() don't require &mut self or exclusive access. Since internally they already use separate channels (cmd_tx is an mpsc::Sender which is Clone, and event_rx is already behind its own Arc<Mutex>), you can:

1. In crates/rustyclaw-desktop/src/gateway/client.rs, make cmd_tx a tokio::sync::mpsc::Sender (already is) and remove the outer Mutex<GatewayClient> requirement.
2. In crates/rustyclaw-desktop/src/app.rs line 19, change the type from Signal<Option<Arc<Mutex<GatewayClient>>>> to Signal<Option<Arc<GatewayClient>>>.
3. In the event loop (app.rs:42-51), call client.recv().await directly without locking.
4. In on_submit (app.rs:64-71) and other handlers, call client.chat(message).await directly without locking.
5. This works because send() uses cmd_tx (cloneable Sender) and recv() uses event_rx (already behind its own internal Mutex).

@copilot Can you fix the CI errors and the merge conflicts?

@copilot Can you fix the CI errors and the merge conflicts?

Fixed in commit f8fdd00.

Merged origin/main and resolved the conflict in ssh.rs (used main's version). The CI errors were caused by:

1. Missing StdioTransport export — added to gateway module re-exports
2. Wrong Transport trait version — replaced transport.rs with main's version (PeerInfo/TransportWriter/WebSocketTransport design)
3. Desktop dioxus version mismatch — dioxus-bulma 0.7.2 requires dioxus 0.7; updated Cargo.toml from 0.6 to 0.7
4. Wrong API names in desktop client — fixed Color:: → BulmaColor::, Size::Small → BulmaSize::Small, and corrected ClientFrameType/ClientPayload variant names (Auth → AuthResponse, VaultUnlock → UnlockVault, etc.)
5. Borrow conflict in tool_call.rs — fixed is_collapsed mutable+immutable borrow
6. Redundant test-bind block — removed the duplicate TcpListener::bind test since origin/main already handles bind failures at the initial bind site with proper error context

@copilot CI is failing please fix.

Fixed in commit feb315b. The CI failures were all in two areas:

rustyclaw-desktop crate (all platforms):

• E0277: connect_async(&url) → connect_async(url.as_str()) to avoid tungstenite version diamond conflict
• E0369: Added PartialEq to ChatMessage, ToolCallInfo, and ThreadInfo in state.rs (required by dioxus Props derive)
• E0599: Fixed Field { label: "..." } → FieldLabel { "..." } (dioxus-bulma 0.7 API change)
• E0599: Fixed PngEncoder::encode() → write_image() (image 0.25 API change)
• E0308: Fixed ThreadCreate { label } type mismatch (Option<String> → String) and ThreadInfoDto field conversions
• E0502: Fixed step borrow conflict in hatching.rs by pre-computing current_step/is_next_disabled before rsx!
• E0282: Exported HatchingResult from components/mod.rs to fix type inference, replaced invalid Field_addons with Field { addons: true } + Control { expanded: true }

rustyclaw-core with --features full (ssh feature):

• Added debug to tracing imports, use std::path::Path for #[cfg(feature = "ssh")] functions, and TransportAcceptor to the transport trait imports

@copilot Still failing, please fix.

Fixed in commit 73e60c7. The remaining failures were all in rustyclaw-desktop:

• E0603 protocol private — re-exported GatewayCommand from gateway/mod.rs
• E0603 pairing private — re-exported generate_qr_code from components/mod.rs; updated app.rs to use imported items instead of crate-path references
• E0282 type annotation — added explicit HatchingResult type on the on_complete closure in app.rs
• E0382 moved value — cloned props.public_key before the handle_copy closure in pairing.rs
• future not Send — replaced tokio::spawn with dioxus spawn in pairing.rs (dioxus Signal is not Send)

@copilot The integration tests are failing becase of this:
The system library glib-2.0 required by crate glib-sys was not found.
The file glib-2.0.pc needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
The PKG_CONFIG_PATH environment variable is not set.

HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing glib-2.0.pc.

We may need to modify the test for this to work right. We'll need to be able to run the tests with the dependent libraries installed.

Fixed in commit a0395ba. The integration-tests and e2e-tests jobs were missing the sudo apt-get install -y libgtk-3-dev libwebkit2gtk-4.1-dev step that the check and test jobs already had. Added it to both jobs so cargo build can resolve the glib-2.0/gio-2.0/gobject-2.0 system libraries required by the desktop crate.

🟡 build-release CI job missing GTK/WebKit system dependencies for desktop crate

The build-release job for native Linux (x86_64-unknown-linux-gnu, use_cross: false) runs cargo build --release on the entire workspace. Since rustyclaw-desktop is now a workspace member requiring dioxus with desktop feature (which depends on GTK/WebKit), this build will fail because the job doesn't install libgtk-3-dev and libwebkit2gtk-4.1-dev. Other jobs (check, test, integration-tests, e2e-tests) correctly install these dependencies, but build-release and lint do not. The build-release job does not have continue-on-error, so it would block release artifact creation on tag pushes.

🔴 Chat sends only the latest message instead of full conversation history

The command_to_frame function sends only vec![ChatMessage::text("user", &message)] — a single-element vector with just the latest user message. The gateway forwards these messages directly to the model provider (crates/rustyclaw-core/src/gateway/mod.rs:1304-1311). Without prior conversation history, the model has no context of the ongoing conversation, so every message is effectively a new standalone request.

The TUI client correctly maintains a conversation: Vec<ChatMessage> that accumulates all user and assistant messages, sending conversation.clone() with each request (crates/rustyclaw-tui/src/app/app.rs:444-451). The desktop client needs similar behavior — either accumulate messages locally or restructure the GatewayCommand::Chat to accept the full history.

Prompt for agents

The desktop client's command_to_frame function at crates/rustyclaw-desktop/src/gateway/client.rs:148-153 creates a Chat frame with only the latest user message. The gateway passes whatever messages it receives directly to the model provider, so the model loses all conversation context.

The TUI client (crates/rustyclaw-tui/src/app/app.rs:435-529) maintains a local conversation Vec<ChatMessage> that accumulates messages across the session, and clones the full history into each Chat frame.

To fix this:
1. Change GatewayCommand::Chat to carry a Vec<ChatMessage> instead of a single String
2. In app.rs on_submit handler, build the full message history from state.messages (converting the desktop ChatMessage structs to the core ChatMessage type) and pass it to the command
3. Also handle assistant responses: when GatewayEvent::ResponseDone arrives, the accumulated assistant text should be included in subsequent chat requests
4. The messages should include a system prompt as the first message, matching the TUI client behavior

Relevant files:
- crates/rustyclaw-desktop/src/gateway/protocol.rs (GatewayCommand::Chat definition)
- crates/rustyclaw-desktop/src/gateway/client.rs (command_to_frame function)
- crates/rustyclaw-desktop/src/app.rs (on_submit handler)

@copilot Two CI pipelines are still failing. If you need to modify the pipelines, you can, if you need to add feature gates to avoid causing errors, that's fine too.

@copilot Two CI pipelines are still failing. If you need to modify the pipelines, you can, if you need to add feature gates to avoid causing errors, that's fine too.

Fixed in commit 6c30aa7. Both failures were linker errors: rust-lld: error: unable to find library -lxdo. Added libxdo-dev to the apt-get install step in both integration-tests and e2e-tests jobs — this library is required when linking rustyclaw-desktop but wasn't needed for cargo check (which skips linking).

🟡 CI lint job missing system dependencies for desktop crate, breaking clippy

The lint job runs cargo clippy --all-targets --all-features which now includes the rustyclaw-desktop crate (added to the workspace in this PR). However, unlike the test, integration-tests, and e2e-tests jobs, the lint job doesn't install libgtk-3-dev and libwebkit2gtk-4.1-dev. The desktop crate's Dioxus dependency with desktop feature requires these libraries to compile, so clippy will always fail on this workspace member. While continue-on-error: true masks the failure, it means clippy results for all crates (not just desktop) are silently lost.
