* Stop profiling on exit of main goroutine
Previously, profiling was stopped since Stop() method was called on exit of cli.BeforeFunc.
This lead to profiling to be stopped prematurely.
* Moved profiling switch statement to a separate func
* posix: Avoid using getAllVolumeInfo() in getVolumeDir()
This is necessary compromise to avoid significant slowness this
causes under load. The compromise is also substantial in a way
so that to avoid penalizing common cases v/s special cases.
For buckets with Caps on Unixes, we filter buckets based on the
latest anyways, so this is completely acceptable.
* XL/fs: Change the usage of verification of existance of buckets.
Optimize calling isBucketExists, it is not needed for all call
paths. isBucketExist should be called only for calls which use
temporary volume location for operations, for the rest rely on
the errors returned on their original call path.
Remove usage of filtering as well across all volume names.
Since config dir, supplied as command line argument, is parsed after pprof
output directory is determined, pprof output files are written in ~/.minio/profile
directory instead of <configDir>/profile/. This change fixes this behaviour.
This patch brings in the removal of debug logging altogether, instead
we bring in the functionality of being able to trace the errors properly
pointing back to the origination of the problem.
To enable tracing you need to enable "MINIO_TRACE" set to "1" or "true"
environment variable which would print back traces whenever there is an
error which is unhandled or at the handler layer.
By default this tracing is turned off and only user level logging is
provided.
Previously when wrong set of disks are given with last minio server
run, it throws unclear error message. This is fixed by returning
appropriate errors.
Fixes#1591
When a disk is removed while an operation is going on
(eg. single/multipart put object, list/multipart list objects etc),
its required to ignore errDiskNotFound error and continue the
operation.
Fixes#1552
Since there is a good amount of overlap, each code has to lock
properly for the operation they are going to perform.
- MakeVol create vols in a routine on all disks, hold locks.
- DeleteVol delete vols in a routine on all disks, hold locks.
- StatVol stat vols in a routine on all disks, hold locks.
Fixes#1588
The functionality provided by minhttp will be implemented
cleanly through our own APIs. Since we are not going to
send SIGUSR2 and manage configuration in that manner, it
doesn't make sense to use minhttp.
Fixes#1586
