----------------------------------------
Summary: Remove aquirence of any locks from toString methods
Key: IGNITE-7892
URL: https://issues.apache.org/jira/browse/IGNITE-7892
Project: Ignite
Issue Type: Wish
Components: general
Affects Versions: 2.4
Reporter: Alexander Belyak
In org.apache.ignite.internal.processors.cache.GridCacheMapEntry we have thread
safe toString() method that can lead to some hangs of monitoring threads like
grid-timeout-worker if we try to dump LongRunningOperations with locked entry.
I think that toString methods will never need to be a thread safe and can throw
ConcurrentModificationException or print inconsistent data, so we must remove
synchronization from every toString methods in codebase. If we need some
"consistent" string representation - let's add consistentToString methods or do
external synchronization.
