TomZz	2d5062ed75	feat: implement pixel-perfect custom rendering for block elements, powerline and box drawing - Render block elements (U+2580-U+259F), box drawing lines, and powerline characters using precise GPUI vector paths instead of fonts. - Snap logical coordinates to exact physical pixels using window.scale_factor() to perfectly eliminate SDF anti-aliasing gaps and bleeding. - Fixes visual seams in terminal UI layouts.	2026-06-15 01:14:42 +08:00
TomZz	d7d6faeeb1	feat: optimize transfer history dialog UI and logic - Add an independent scrollbar track to prevent it from overlapping with the content list - Add a "Clear History" button with text label, placed seamlessly next to the close button in the custom header - Implement a 100-record limit for transfer history and display this limit in the header - Persist the cleared transfer history into the session config immediately after clearing - Disable default dialog close button and reconstruct header to avoid state update collision and panic Resolves #25	2026-06-14 23:58:46 +08:00
TomZz	19a4274473	feat: enhance UI for active tabs and settings dialog - Active Tab: Now uses `FontWeight::BOLD`, `text_base()` font size, and the primary theme color. This makes it far more distinct from inactive tabs, especially in themes where background differences are subtle. - Settings Dialog: Overrode the default sidebar style to use the main dialog background (`cx.theme().background`), seamlessly blending the sidebar with the content pane. - Refactor: Renamed unused `_cx` parameter to `cx` in the settings dialog render closure since it is now being utilized to access the theme.	2026-06-14 23:34:01 +08:00
TomZz	4bb3bee6c8	fix: ensure selection background fully covers wide characters (#24 ) Rationale: Previously, the terminal renderer generated background highlight rectangles (`LayoutRect`) with a hardcoded width of 1 cell (`cells: 1`) for every character. For full-width CJK characters (which carry the `Flags::WIDE_CHAR` flag and visually span 2 columns), this caused the selection and custom background colors to render across only half of the character's visual width. This fix correctly interprets the terminal cell flags during layout generation: if a cell possesses `Flags::WIDE_CHAR`, it generates a background rectangle spanning 2 cells (`cells: 2`). As a result, the highlight now matches the exact bounds that the text occupies in the terminal grid, cleanly fixing the partial highlighting of Chinese text.	2026-06-14 23:19:33 +08:00

TomZz	8a535fad5a	fix: fallback to ssh-rsa signature for legacy OpenWrt dropbear Resolves issue #20 where RSA 4096-bit keys failed to authenticate on OpenWrt Dropbear servers. The previous logic exclusively tried rsa-sha2-512 and rsa-sha2-256, which caused authentication aborts on servers only supporting legacy ssh-rsa (SHA-1) signatures. - Modified `private_key_with_alg` to `private_keys_with_algs` to return a list of supported algorithms including SHA-1 fallback for RSA keys. - Implemented an iterative algorithm fallback loop in both SSH and SFTP connection authentication phases.	2026-06-14 14:22:24 +08:00

TomZz	33a3d624b7	Refactor: integrate comprehensive tracing logs and SSH multiplexing This commit introduces a robust logging system and optimizes remote metric collection over SSH: - Logging Infrastructure: - Replaced ad-hoc `eprintln!` and `println!` with the `tracing` crate. - Implemented a rolling file appender in `~/.config/ashell/log/` keeping the last 6 minutes of logs. - Restricted stdout logging to debug builds only, keeping release builds clean. - SSH Multiplexing & Performance: - Shared `russh::client::Handle` across tasks using `Arc<Mutex<>>`. - Replaced the 5-second polling of new SSH connections with `SampleMetrics` over the existing channel. - Eliminated authentication log spam and vastly improved polling latency. - Optimized terminal `resize` events to only trigger when dimensions actually change, further reducing UI layout spam and backend load. - Application & Network Auditing: - Log window lifecycles (open, close). - Log UI actions such as session connects and tab closures. - Detailed connection logs distinguishing between graceful EOFs, network drops, and abrupt closures. - Granular SFTP tracking including directory navigation, creation, batch uploads/downloads, and online file editing.	2026-06-14 13:57:50 +08:00

TomZz	e7e2c67393	fix: restore body_panels layout sizes on app startup - Ensure the size of the monitoring panel (the second child of body_panels) is explicitly loaded from configuration rather than falling back to the hardcoded default of 328px.	2026-06-13 03:01:40 +08:00
TomZz	47b03510b2	feat: optimize monitoring card layout for memory and disks - Hide swap memory progress bar entirely if total swap is 0. - Add temporary overlay scrollbar for the disk list using ScrollbarShow::Scrolling, allowing users to scroll through long disk lists without displaying a persistent scrollbar UI. - Fix unused variable and dead code cargo warnings.	2026-06-13 02:56:11 +08:00
TomZz	54c50c871a	feat: fix SFTP monitoring panel minimize behavior and layout - Isolated the monitoring panel from ResizableState when minimized to prevent the GPUI flex layout and proportional resize engine from forcing it out of the window bounds. - Wrapped the terminal's resizable container with flex_1 to constrain it to available space, preventing the fixed-height 114px panel from overflowing the bottom of the screen. - Saved the user's dragged panel size (prev_monitoring_size) immediately before minimizing. Double-Frame Delay Update Reason: When expanding the panel from 1 child back to 2 children, ResizableState needs one full render frame to recognize the child count change, append the new panel, and initialize its zero-size defaults. If we update the sizes synchronously on the first frame, ResizableState would overwrite our manual sizes during its layout initialization. Waiting for a double-frame delay guarantees that ResizableState has fully populated the second panel in its internal state, allowing us to accurately restore the user's previously dragged height without being overridden by the layout engine.	2026-06-13 02:42:04 +08:00
