Fix improper handling of msg.results in chunk callbacks (#964)

[jongwoo328]

Fix #964.

The delete msg.results; statement was likely introduced for memory optimization.
However, this caused the results to not be correctly passed as a parameter to complete when a chunk callback was present.

To address this, the release point of msg.results has been adjusted to ensure that results are properly passed to complete in cases where a chunk callback is used.

Thanks for submiting the PR.

Do you think it should be easy to have a test suite which tests that the chunk Callback gets proper results? It will be great to include such test to prevent any regresion on the future.

Could you elaborate why wee need to terminate the worker only when a function is defined?

I think I may have unintentionally changed the original flow while modifying the code. I'll revert back to. Thank you.

Sure.

Should I add test to the node_test.js and CUSTOM_TEST in test-cases.js?

test-cases.js sounds like the right path for such test.

I will wait for your test before merging this.

I've addressed my mistakes and adding tests.
Please let me know if there's anything else that needs to be adjusted.
Thank you for your guidance!

I've run the test and I see your new test is failing. Could you have a look and address it? TIA

Previous fixes didn't work on node environments 😅.
When using ChunkStreamer in a node environment, the _completeResults value being passed to complete was being set to undefined if the user provided the chunk option (in parseChunk).
I added code to store the results in _completeResults before setting results to undefined so that result can be properly passed to complete even if the chunk option is given.

Now it passes all tests!
