Add async_iterable_to_stream utility to avoid aiohttp compatibility issues 
Create async_iterable_to_stream() in gns3server.utils.asyncio that
converts an async iterable to an aiohttp StreamReader via a background
feeder task. This bypasses aiohttp's AsyncIterablePayload which can
cause 'Connection reset by peer' with certain HTTP servers.

Use it in _run_http_query for the __aiter__ data path.

cda5fdd94b feat(telnet_server): improve error handling and connection management 
- Catch OSError alongside ConnectionError in connection processing to handle more network errors
- Move client_info retrieval inside try block to prevent AttributeError on failed connections
- Replace bare except with specific exceptions (OSError, ConnectionError, asyncio.TimeoutError)
- Improve error logging to include specific exception details and client information

e4faf673af fix(telnet): handle connection race condition during broadcast 
Fixes two critical issues in telnet server when clients rapidly
   connect/disconnect during broadcast operations:

   1. **OSError [Errno 107]**: Transport endpoint not connected
      - Root cause: getpeername() called outside try block
      - Fix: Move getpeername() inside try block and catch OSError
      - Expand exception handling to include OSError and TimeoutError

   2. **KeyError**: Double deletion from connections dictionary
      - Root cause: Connection deleted in broadcast loop, then deleted
        again in top-level exception handler
      - Fix: Use dict.pop(key, None) instead of del dict[key]

   **Changes**:
   - Line 216: Add OSError to top-level exception handler
   - Line 227-228: Use pop() to avoid KeyError on double deletion
   - Line 305-316: Move getpeername() inside try block, expand
     exception types, use pop() for safe deletion

   **Impact**:
   - Prevents unhandled exceptions from propagating to asyncio event loop
   - Ensures proper resource cleanup even with race conditions
   - No resource leaks or zombie connections
   - Long-lived clients unaffected by rapid client disconnects

   **Test Script**:
   - Added stress test script to reproduce the issue
   - Supports IOU-L3, VPCS, and generic device types
   - Rapid clients send broadcast-triggering commands (show/run/OSPF)

   **Related**: Fixes bug documented in docs/bugs/telnet-server-connection-race-condition.md

763ef24108 Address the telnet console bug. Add wait_for for drain() call. If we're stuck on drain then the buffer isn't getting emptied. 5 seconds after drain() blocks, exception will be thrown and client will be removed from connection table and will no longer be a problem. 2024-02-02 22:09:31 -05:00

Update telnet_server.py 
Set tcp keepalive timers to 60 seconds. Seems to default to 2 hours on ubuntu 22. Most firewalls will age out an idle tcp session at 1 hour.

Will not address telnet console failing after a tcp session has failed (TimeoutError).
