Hi Mr. Biveinis,

Thank you for your bug report.

I hope that you agree that this report belongs to the category for the tests for NDB storage engine.

Also, please let us know if this is OS-specific issue. Let us know if this test is successful on some other platform. This is important for the further processing of your report.

The test passes on x86_64 Ubuntu 22.04 for me with the same build options.

Hi,

You are having issues on Intel MAC or on Mx MAC ?

Thanks

Thanks for the report, I verified it on M1

Hi Laurynas, 

NdbProcess and its test improved significantly from 8.2.0 to 8.3.0, so the current test output does not match the bug report, but I was able to reproduce the issue.

In testNdbProcess-t read_response() uses a 50 msec. timeout waiting for a pipe to become readable. Apparently this is insufficient under ASAN. I was able to make the test pass by increasing the timeout to 250 msec.

Fixed in NDB 8.4.0.

Issues is in testing only, no user-visible changes, so no changelog entry is required.

Thanks!

Closed.
