This change is a simplification over existing
code since it is not required to have a separate
RPCClient structure instead keep authRPCClient can
do the same job.
There is no code which directly uses netRPCClient(),
keeping authRPCClient is better and simpler. This
simplication also allows for removal of multiple
levels of locking code per object.
Observed in #5160
Since go1.8 os.RemoveAll and os.MkdirAll both support long
path names i.e UNC path on windows. The code we are carrying
was directly borrowed from `pkg/os` package and doesn't need
to be in our repo anymore. As a side affect this also
addresses our codecoverage issue.
Refer #4658
This removal comes to avoid some redundant requirements
which are adding more problems on a production setup.
Here are the list of checks for time as they happen
- Fresh connect (during server startup) - CORRECT
- A reconnect after network disconnect - CORRECT
- For each RPC call - INCORRECT.
Verifying time for each RPC aggravates a situation
where a RPC call is rejected in a sequence of events
due to enough load on a production setup. 3 second
might not be enough time window for the call to be
initiated and received by the server.
Make sure to skip reserved bucket names in `ListBuckets()`
current code didn't skip this properly and also generalize
this behavior for both XL and FS.
* Rename GenericArgs to AuthRPCArgs
* Rename GenericReply to AuthRPCReply
* Remove authConfig.loginMethod and add authConfig.ServiceName
* Rename loginServer to AuthRPCServer
* Rename RPCLoginArgs to LoginRPCArgs
* Rename RPCLoginReply to LoginRPCReply
* Version and RequestTime are added to LoginRPCArgs and verified by
server side, not client side.
* Fix data race in lockMaintainence loop.
Previously, more than one goroutine calls RPCClient.dial(), each
goroutine gets a new rpc.Client but only one such client is stored
into RPCClient object. This leads to leaky connection at the server
side. This is fixed by taking lock at top of dial() and release on
return.
