#673 closed defect (fixed)

logging in snark creates garbage even when disabled

Reported by: Zlatin Balevsky Owned by: zzz
Priority: minor Milestone: 0.9.2
Component: apps/i2psnark Version: 0.9.1
Keywords: logging OOM garbage Cc:
Parent Tickets: Sensitive: no

Description

example ​http://pastethis.i2p/show/1543/

reason: even if logging at debug level is disabled, java will evaluate the arguments before they get put on the stack. Evaluating all these strings & java.util.Date objects is expensive.

Fixing requires all such uses to be prefixed by a predicate like is done in other parts of the code

of course, left over from original port to I2P years ago.

but if logging is causing you to oom you have other problems…

see comment on ticket #674 why OOM stack traces don't really mean anything and instead heap dumps should be used for post-mortem analysis, or pofilers for runtime analysis
