Release notes

Sourced from moka's releases.

Moka 0.12.15

Version 0.12.15

Fixed

• Fixed a bug where re-inserting an expired entry could cause it to lose its expiration time and remain in the cache indefinitely when using a custom Expiry policy with per-entry expiration. (#582gh-pull-0582 by @​jiangzhe, #581gh-pull-0581 by @​atrocities, reported in #575gh-issue-0575):
  • This occurred when an entry that had expired but not yet been evicted was re-inserted, and expire_after_update returned None. This primarily affected users who only override expire_after_create, since the default expire_after_update returns duration_until_expiry, which is None for expired entries.
  • This bug was introduced by the changes in v0.12.13 (#549gh-pull-0549 and #564gh-pull-0564).
  • Subtle behavior change:
    • Before this fix, re-inserting an expired entry was treated as an update, so Expiry::expire_after_update was called.
    • After this fix, re-inserting an expired entry is treated as a creation, so Expiry::expire_after_create is called instead.
    • This may change the expiration time of re-inserted entries, depending on your Expiry trait implementation.
• Fixed flaky tests cht::segment::tests::drop_many_values and drop_many_values_concurrent that were failing on high-core-count machines (#586gh-pull-0586):
  • These tests were using a CPU-dependent segment count, causing inconsistent bucket array shrinking behavior of the internal segmented hash map across different machines.
  • Changed these tests to use a fixed segment count (4) for consistent results.

Changed

• Disabled flaky GC-dependent tests by default using run_flaky_tests cfg (#584gh-pull-0584):
  • These tests rely on epoch-based garbage collection (crossbeam-epoch) timing that is not guaranteed, causing intermittent failures.
  • Fixed #539gh-issue-0539 and #580gh-issue-0580.
  • To run these tests, set RUSTFLAGS='--cfg run_flaky_tests'.
