The _stty_sent guard prevented the container shell from updating its
terminal size after the first resize. This caused visual mismatches
where xterm.js displayed at the new size but the shell still wrapped
output at the old size.
Remove the guard so stty is sent on every resize event.
- Frontend: Add ResizeObserver with dimension tracking for accurate resize detection
- Frontend: Fix cleanup function to properly disconnect ResizeObserver
- Frontend: Use CSS grid for terminal wrapper layout
- Backend: Add duplicate dimension check to avoid unnecessary resizes
- Backend: Ensure stty command is sent correctly to container shell
The ResizeObserver detected size changes caused by the stty command
output appearing in the terminal, creating an infinite resize loop:
1. Resize detected -> fit() -> send resize to backend
2. Backend sends stty command through PTY
3. stty text appears in terminal output
4. ResizeObserver detects content height change
5. fit() calculates new rows -> send resize
6. Loop continues forever
Reverted to:
- Window resize event instead of ResizeObserver
- stty command only sent once on first resize
This means the container shell stays at the initial size and won't
dynamically resize when the browser window changes, but prevents
the infinite loop.
Previously the stty command was only sent on the first resize. Now it
is sent every time the terminal dimensions change, so resizing the
browser window or rotating the device properly updates the container
shell size. Added a check to skip when dimensions haven't changed.
Docker exec doesn't forward PTY resize to the container process,
so the container bash stays at 80x24 regardless of frontend resize.
Work around this by sending a stty command through the terminal
on first resize to set the correct dimensions inside the container.
The write loop was crashing with 'name instance_id is not defined' when
processing resize messages. This caused the connection to drop with 1006
and the frontend to reconnect in a loop. Fixed by passing instance_id
as a parameter to _write_loop. Also cleaned up debug logging.
When any of the read/write/heartbeat loops ends, we were cancelling
remaining tasks but not explicitly closing the WebSocket. This caused
the connection to be dropped with 1006 abnormal closure instead of
a clean 1000 close. The frontend then reconnected, creating a loop.
Docker exec doesn't forward PTY resize to the container process,
so the container bash stays at 80x24 regardless of frontend resize.
Work around this by sending a stty command through the terminal
on first resize to set the correct dimensions inside the container.
Sending SIGWINCH to the docker exec process was crashing/killing it,
which closed the PTY and caused WebSocket 1006 abnormal closure loops.
Reverting to the original TIOCSWINSZ-only approach.
When resizing the PTY, docker exec needs to be notified so it can
re-read the terminal size and propagate it to the container's PTY.
Without this, the container shell stays at 80x24 regardless of what
the frontend sends.
TerminalManager was trying to create an asyncio task at module import time,
but no event loop exists yet during import. This caused RuntimeError on startup.
Changes:
- _start_idle_check() now checks if event loop is running before creating task
- If no loop exists, silently skips (will be started lazily)
- Added lazy start call in get_or_create_session() when websocket connects
- Backend: Send ping every 30s from WebSocket endpoint
- Frontend: Respond to pings with pongs, detect missed pings (60s timeout)
- Update type definitions to include 'resetting' status
Refs: persistent-terminal-sessions task 6.4
- Terminal sessions now persist across WebSocket disconnections
- Added circular output buffer (10KB) for replay on reconnect
- Added idle timeout cleanup (30 minutes)
- Added reset functionality via WebSocket message and HTTP endpoint
- Concurrent connections close old WebSocket when new one connects
- Frontend: Added reset button with confirmation dialog
- Frontend: Handle resetting status and reconnection
Refs: persistent-terminal-sessions
- Add safety check after rendering compose template to ensure REPO_PATH is mounted
- If compose template lacks volume mount, auto-add default mount to /workspace
- Add cloned repo verification to catch empty clone directories
Refs: clone mode repo not appearing in container workspace
Backend:
- Add created_at to get_user_sessions response
Frontend:
- Hide tunnel error badges, probe output, and 'Recreate Tunnel' button for terminal-only sessions
- Show session start time (created_at) in active sessions list
- Show repository configuration (clone_mode, branch) for each session
- Skip health check polling for terminal-only sessions
- Update Session type to include created_at field
Git branch -a --format=%(refname:short) returns remote branches as
'origin/branch-name', not 'remotes/origin/branch-name'. The code was
only filtering 'remotes/' prefix, causing clone to fail with branch
names like 'origin/feat/foo'.
Now properly detects remote names using 'git remote' and strips the
remote prefix (e.g., 'origin/') from branch names.
Resolved conflicts:
- Moved branch selection UI from inline sessions.tsx to CreateSessionForm component
- Integrated branch dropdown and new branch creation into CreateSessionForm
- Removed duplicate branch state management from sessions.tsx
All branch selection tests pass (7/7).
- Add new_branch field to CreateInstanceRequest
- Run git checkout -b after cloning when new_branch is provided
- Store new branch name in ToolInstance record
- Drop is_builtin column from tool_types table
- Remove built-in tool seeding from startup
- Remove is_builtin from API schemas and frontend types
- Update tool-types spec to reflect removal of built-in concept
- Add Alembic migration for column removal
- Update tests to work without built-in distinction
Remove 500-character truncation on probe output so users can see
all attempts including the final successful one. Add probe status
indicator (passed/failed/pending) that's always visible when probe
data exists.
The backend was returning 'tool_type_interface_type' (string) but the
frontend expected 'tool_type_interfaces' (array). This caused
undefined.includes() crash when clicking Open on terminal sessions.
Changed both list_instances and get_user_sessions to return
tool_type_interfaces as an array. Also added clone_mode and branch
to get_user_sessions response.
For terminal-only tools like OpenCode, default_port is 0 which is falsy
in Python. The code incorrectly treated port 0 as 'not configured' and
marked the instance as error. Now we only check if tool_type exists,
and default to port 0. Terminal tools skip tunnel creation anyway.
For terminal-only tools (no URL), only check container status for
overall health instead of requiring tunnel health. Terminal tools
do not have tunnels, so tunnel_status stays as 'not_applicable'
which was failing the healthy check.
