v4auth will default to true and if the frankfurt (eu-central-1) region
is selected with v4auth set to false explicitly, the driver will error
out upon initialization.
The secure flag will be true by default and will change the
s3 endpoint of the region to http instead of https when selected as false.
The main benefits of running with secure being false is that it apparently
has a roughly 33% performance boost (even on pure data transfer, not only
connection setup which is what I would have expected).
This requires some discussion of how we will handle errors due to network problems
and after further changes in that direction some more stress testing. There is also an
upcomming commit implementing zero fill on WriteStream when offset is greater than
the current size of the file.
The packages causing build errors are being disabled for now to let us split up
the work in the different driver implementations without blocking integration
into the main branch. The s3 and azure implementations need some effort to add
Stat support. The ipc package needs that work plus some care around hanging
send calls.
Custom storage drivers can register a factory to create the driver by
name, similar to the database/sql package's Register and Open
factory.Create returns an in-process driver if registered or an IPC
driver if one can be found, erroring otherwise
This standardizes parameter passing for creation of storage drivers
Also adds documentation for storagedriver package and children
