Issue Addressed
Presently the random slasher tests crash after a few thousand iterations with an error about file descriptor exhaustion. The reason for this is that we use
Box::leakto give the slasher database a'staticlifetime. As a result, if more than 1SlasherDBis ever created, its destructor will not run and the open files will never be closed. Even though thetempdirwill delete the DB directory containing the files, this does not free theProposed Changes
Reuse the same database for each test rather than creating a new one. The contents of the database are deleted completely between iterations. Some refactoring to allow changing the
configbetween iterations was required.Additional Info
You can reproduce the crash after a few minutes running this command on
unstable:After this PR, it can run indefinitely.
