Description Mohamed Ashiq 2015-09-02 06:37:43 UTC
+++ This bug was initially created as a clone of Bug #1246794 +++

GF_LOG_NONE (0) which was inadvertently used causing https://bugzilla.redhat.com/show_bug.cgi?id=1246728 

Shouldn't GF_LOG_NONE mean "Never log this"? If so, it's not being tested for and is, instead, treated as a higher priority than CRITICAL thus is always logged.

The enum, gf_level_strings is used for two things

a. Admin perspective - Messages with what log level and above the admin is interested in. In this case GF_LOG_NONE means admin wants gluster to never log.

b. Developer perspective - At what level this particular message should be logged at. In this case, GF_LOG_NONE has *no* meaning. Why would a developer call gf_msg and say take this message but don't log it.


The original bug was because we did call gf_msg in one place with log_level of NONE and it was fixed with http://review.gluster.org/#/c/11760.

I would suggest that the only change we do is to only change logic in logging.c to do a special check for GF_LOG_NONE used by a developer for a message and skip that log message Or rather log at GF_LOG_DEBUG complaining that gf_msg is called with GF_LOG_NONE and should never be done.

I can see that. If that's what's done, there needs to be an integration test along with that which fails if the complaint that gf_msg is called with GF_LOG_NONE (or GF_LOG_ZERO or GF_LOG_UNDEF or whatever)
