[Bug 19523] New: Koha:: Cache changes not passed to all plack workers with in-memory caching.
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=19523 Bug ID: 19523 Summary: Koha::Cache changes not passed to all plack workers with in-memory caching. Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: Architecture, internals, and plumbing Assignee: koha-bugs@lists.koha-community.org Reporter: olli-antti.kivilahti@jns.fi QA Contact: testopia@bugs.koha-community.org REPRODUCE: - $KOHA_CONF shouldn't have any <memcached_* -definitions. This triggers in-memory cache usage. - plack workers is atleast 2 - Change some easily visible syspref, such as 'languages'. The syspref change applies only to the worker thread where the change was made. Other worker threads keep using the old syspref. - Observer that 50% of time the old syspref is used. Other times the new syspref is used. - Reduce plack workers to 1. Observe no issues with syspref change taking effect. Using memcached solves this problem. It is still useful to fix it for those who don't want to use memcached. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
