Debug adapter process has terminated unexpectedly

[sswaroopgupta]

Expected behavior
Should be able to debug seamlessly

Actual behavior
Debug adapter process has terminated unexpectedly

Steps to replicate

• Create a gauge-python project
• Debug Spec
• Debug Scenario
• Debug Spec

The message appears Debug adapter process has terminated unexpectedly

Version

Gauge version: 0.9.8.nightly-2018-04-26
Commit Hash: 5bd699e

Plugins
-------

The Python process CPU usage is almost 100 in this scenario when Debugging is hung

[BugDiver]

Cause of the Issue

• The vs code python debugger crashes sometimes Debug adapter process has terminated unexpectedly microsoft/vscode-python#618, debug adapter process has terminated unexpectedly microsoft/vscode#45109
• We start runner in debug mode and wait for a debug client to attach, but if it crashes it won't attach and the runner will keep waiting, which eventually causes the high CPU usages.

Possible fix/workaround

• Vscode does not provide a way the handle debug the crash,
• A timeout can be added in runners after which runner can print on the console that debugger did not attach in given time and quit.
• vscode can intercept the console output and Show notification and stop the running gauge process.

the fix should be available in following nightlies -

• gauge-vscode - 30-04-2018
• gauge-python - 30-04-2018

@sguptatw Can you tell what are you getting?

[sswaroopgupta]

Debug adapter process has terminated unexpectedly
The steps to replicate are the same as the original issue.

Observation: The number of times the Debug Spec and Debug Scenario can vary.

@sguptatw We can't fix debugger crash problem coz it's a problem with vscode-python.
The fix is about the high CPU usage. Please refer the above comment. It's a workaround which we have done.

@BugDiver The user should be able to stop debugging and proceed with other IDE actions.
Clicking on stop debugging does not stop the gauge process/debugging process. Currently user has to restart the IDE to continue with other IDE actions.
