Quick-pick lifecycle & abandonment cleanup - #98
Conversation
The frameless transparent shell and modal surfaces needed clearer interaction behavior without reintroducing native decorations or modal backdrop blur. This keeps the app-drawn frame minimal, removes full-window backdrop blur from modal-like overlays, and makes draggable modals behave predictably from header handles only. Constraint: Tauri window is frameless and transparent, so visible framing must be drawn inside the app surface Rejected: Restore native OS decorations | would conflict with the custom chrome and rounded transparent window Rejected: Drag entire modal surface | would interfere with controls, text selection, and scrollable content Confidence: high Scope-risk: moderate Directive: Keep modal drag initiation constrained to headers unless every interactive child path is re-tested Tested: npm run type-check Tested: CHANGELOG.md updated under Unreleased Not-tested: Manual Tauri window drag/focus QA on macOS/Linux
Connection cancellation previously depended mostly on connection id, which let stale cancel requests race newer retries and left tab close unable to stop an in-flight connect cleanly. The connect path now registers an attempt before async preparation, carries that attempt through IPC, and only installs a successful backend handle while the same attempt still owns the registry. UI close handling now cancels a last connecting host tab without changing the existing connected-tab confirmation flow. Constraint: Preserve connected-tab confirmation and normal disconnect behavior Rejected: Reuse disconnect for connecting tab close | it can remove established sessions and does not model pending connect attempts Confidence: high Scope-risk: moderate Directive: Keep connect cancellation keyed by attempt id; do not fall back to connection-id-only cancellation without rechecking retry races Tested: npm run test:connection-lifecycle-service Tested: npm run type-check Tested: npm run build Tested: cargo check --manifest-path src-tauri\\Cargo.toml Tested: cargo fmt --manifest-path src-tauri\\Cargo.toml --check Tested: git diff --check
The connection-cancellation fix and UI polish are ready as a patch release, so the app metadata now reports 2.25.1 and the changelog records the implementation commit bf4bf99. This keeps release notes tied to the code commit without trying to embed a self-referential hash in the same commit. Constraint: Changelog entries use concrete implementation commit hashes Rejected: Put this release commit's own hash in CHANGELOG.md | Git hashes change when tracked content changes Confidence: high Scope-risk: narrow Directive: Keep package, Tauri, Cargo manifest, and Cargo lock versions in sync for release bumps Tested: git diff --check Tested: cargo check --manifest-path src-tauri\\Cargo.toml Not-tested: Full npm build after metadata-only version bump

russh 0.46.0 client::Handle Drop disconnect source
💡 Result:
In russh 0.46.0, the drop of a client::Handle does not explicitly trigger a network-level disconnect message to the server [1]. Instead, the library is designed such that the underlying session cleanup is managed by the drop of the session object itself [2][3][4]. When a Handle is dropped, it simply decrements the reference to the session or cleans up its own local resources [1]. If you need to perform an orderly shutdown that informs the remote server, you must explicitly call the asynchronous Handle::disconnect method before the handle is dropped [1]. This method allows you to send a formal Disconnect message with a specific reason, description, and language tag [1]. For resource cleanup within your application (such as removing entries from a tracking map or closing associated local state), the idiomatic approach in russh is to implement the Drop trait for your custom handler, as the handler is dropped automatically when the session is closed [2][5]. If you require notification of disconnection for business logic, you should utilize the disconnected method provided by the client::Handler trait [6].

Disconnect the SSH handle on cancellation.
russh::client::Handle does not send an SSH disconnect when dropped. The SFTP session shuts down its channel on drop, but the SSH handle needs an explicit Handle::disconnect(...) call before returning Err("Connection cancelled".to_string()).

Contain keyboard focus in the restart confirmation.
When showRestartConfirm is true, handleDialogKeyDown includes the settings controls and the confirmation controls in one Tab sequence. Focus also remains on the obscured settings control that opened the confirmation.
Make the confirmation a labelled dialog. Move focus to its Cancel action when it opens. Mark the underlying settings content inert. Trap and restore focus within the confirmation until it closes.

Tauri v2 command argument names camelCase to snake_case conversion invoke
💡 Result:
In Tauri v2, command arguments are converted from Rust's snake_case to camelCase by default when calling invoke() from the frontend [1][2]. This behavior is designed to align with common JavaScript naming conventions [3][4]. To use snake_case for command arguments in your JavaScript code, you must explicitly configure the command using the rename_all attribute [2][5]: rust #[tauri::command(rename_all = "snake_case")] fn my_custom_command(invoke_message: String) { // ... } With this attribute applied, the invoke call in your frontend must match the snake_case naming used in Rust [2][5]: javascript import { invoke } from '`@tauri-apps/api/core`'; // Now uses snake_case instead of camelCase invoke('my_custom_command', { invoke_message: 'Hello!' }); It is important to note that this automatic renaming applies only to the top-level argument names [3]. If your commands accept complex objects (structs) as arguments, any nested fields within those objects will continue to follow their own serialization rules (often inheriting from serde configurations) unless specifically handled [3].

Preserve and re-check cancellation across the full connection attempt.
Cancellation can be missed in two windows: cancelConnect does nothing when no active attempt ID exists yet, and a cancellation set after the final checkpoint can be deleted by finally before the success state update. In either case, a cancelled attempt can still establish a session and be marked connected.
Record pending cancellation by connection ID until the serialized attempt acquires its slot, consume it when the attempt starts, and re-check cancellation immediately before the success state update so the flag cannot be discarded without affecting the result.

In `@src/store/connectionSlice.ts` around lines 748 - 765, Update cancelConnect to
record a pending cancellation keyed by connection ID when
activeConnectAttempts.get(id) is undefined, then have connect consume that
pending cancellation after acquiring the serialized slot. In connect, re-check
cancellation immediately before the success state update so an unobserved
cancellation cannot be discarded by finally; apply these changes at
src/store/connectionSlice.ts lines 748-765 and 739-744.
