7 months agoLockfree journal: Cleanup hook runs only when needed.
Katerina Kubecova [Fri, 6 Dec 2024 12:16:18 +0000 (13:16 +0100)] 
Lockfree journal: Cleanup hook runs only when needed.

The function lfjour_cleanup_hook() was scheduled each time any of the
journal recipients reached end of a block of journal items or read all
of journal items. Because lfjour_cleanup_hook() can clean only journal
items every recipient has processed, it was often called uselessly.

This commit restricts most of the unuseful scheduling. Only some
recipients are given a token alowing them to try to schedule the
cleanup hook. When a recipient wants to schedule the cleanup hook, it
checks whether it has a token. If yes, it decrements number of tokens
the journal has given (issued_tokens) and discards its own token. If
issued_tokens reaches zero, the recipient is allowed to schedule the
cleanup hook.

There is a maximum number of tokens a journal can give to its recipients
(max_tokens). A new recipient is given a token in its init, unless the
maximum number of tokens is reached. The rest of tokens is given to
customers in lfjour_cleanup_hook().

In the cleanup hook, the issued_tokens number is increased in order to
avoid calling the hook before it finishes. Then, tokens are given to the
slowest recipients (but never to more than max_token recipients). Before
leaving lfjour_cleanup_hook(), the issued_tokens number is decreased back.
If no other tokens are given, we have to make sure the
lfjour_cleanup_hook will be called again. If every item in journal was
read by every recipient, tokens are given to random recipients. If all
recipients with tokens managed to finish until now, we give the token to
the first unfinished customer we find, or we just call the hook again.
