chronicle directory-listing.cq4t release

I've upgraded chronicle-queue binaries to the latest version and notice a new file (probably it's not that new but I haven't seen it before) - directory-listing.cq4t.

I have a test creating a regular queue with SingleChronicleQueueBuilder then doing some operations and closing it. As the last step I'm force-deleting the whole folder with the data.

Problem is that directory-listing.cq4t is locked by java process even when queue is already closed. Note that data file itself is deleted without any problems.

There is a test in chronicle code base SingleChronicleQueueTest.shouldCreateQueueInCurrentDirectory which can demonstrate the above behavior as file is not being deleted and delete() call returns false (but result is never asserted)

Is it a known problem or I’m doing it wrong? (queue release)

Solution

  • Thanks for the bug-report. This looks like an oversight where the directory listing was not being closed correctly.

    I've fixed that problem in master. Can you build the latest from github and re-test?
