(cherry picked from commit 75be63a4c8e6b209af6123cb68e13313acd0266c) IJ-MR-9953 GitOrigin-RevId: 657936acb69fbbc59a88e1b7e799f49e81d9f162
Coroutine Debugger support
Java thread stack with coroutine information
- Real frames
- Coroutine 'preflight' frame: SuspendExitMode
is
SUSPEND_LAMBDAorSUSPEND_METHOD_PARAMETER. Location.isPreflight - One or more frames (skipped in debugger)
- Coroutine 'starting' frame: SuspendExitMode
SUSPEND_METHODframe - Restored from coroutine information frames
- Real frames after the 'starting' frame
- Creation frames (only exists if coroutine agent enabled)
Debugger interface
Debugger works as a combination of PositionManager and AsyncStackTraceProvider. Once the 'preflight' signature frame found PositionManager forms a 'preflight' frame with coroutine information which gets processed with AsyncStackTraceProvider.
