A number of the functions in rados do not use the simple error
conversion function where is obviously applies. Convert them to use it.

There is no good reason why the internal error handling support should
be exposed outside the rados package. Make the function lower-cased and
thus private.

In order to get a higher test coverage for rbd/rbd.go, there is a need
to trigger errors for the librbd functions. This makes it possible to
test the error path. The new TestClosedImage() function tricks
RbdImage.validate() into accepting an image that is closed, but still
references the closed image.
librbd is expected to return an error when the image is closed. However,
passing a closed image does not result in stable behavior. Sometimes
librbd causes a panic, at other times there will be a hang and the test
will time-out.
The TestClosedImage() function is disabled, it will skip all testing but
remains available so that it could be enabled in the future.

This fairly hacky script can be used to check how much of the
various apis are covered by the go-ceph library.
It doesn't care about a lot of subtlety at the moment but does
give a fair idea of what types of functions are implemented vs.
those that are not.
Requires the tool 'castxml'.

Run the tests for each sub-package as a separate invocation.
Make the package selectable.
This has a few small advantages:
* When iterating on a single package the other packages do not run
* Better coverage summary line printed after each test
* Slightly better output with verbose test output

In the cephfs tests the setup of the mount/connection was largely being
done as a copy-n-paste. This change adds a common setup function for
most of the test cases that need an active connection.
Similar to other recent changes this also adds a timeout such that
if the test fails to get a connection it will fail quickly rather
than block forever.

When working on the previous rbd change it was determined that the
connection setup code would block forever if the ceph config was missing
or bad when running the tests. Adjust the connection setup in the rados
pkg such that the tests will not block forever.

In the rbd tests the setup of the rados connection was essentially copy
and paste with very little proper error checking.
This change adds a common setup function that checks all error
conditions as well as prevents the tests from blocking forever if
something is wrong with the ability of the tests to connect.

(Re-)enable the revive check for exported vars/functions/etc at the
warning level. We have a lot of pre-existing failures here so we do not
want to fail on these, but we would like a list so we can work on
eliminating them.
Signed-off-by: John Mulligan <jmulligan@redhat.com>
Previously, revive was configured to only warn on detected issues. We
have eliminated all those issues and so can set revive to error out and
thus the 'make check' rule will fail if new issues are introduced.

The arguments passed to Copy() would normally be pointers, just like it
is done with other similar functions. This never worked correctly, as
the arguments were not validated correctly (not recognized) and the
error "Must specify either destination pool or destination image" always
got returned.
Modifying Image.Copy() into something usable would result in a complete
rewrite. Instead of a single Image.Copy() function that tries to cover
rbd_copy() and rbd_copy2(), provide Image.Copy() and Image.Copy2() so
that the API matches the librbd.so interface.

Now that cephfs_test.go is part of the cephfs package, the linter is
checking it and finding errors. Fix them.
Signed-off-by: John Mulligan <jmulligan@redhat.com>
Convert cephfs packages previously unexposed type to a public one and
replace a bunch of the existing boilerplate error handling with a
convenience function similar to those found ind rbd and rados.

The return value of rbd_discard() is the number of bytes that have been
discarded, or in case of an error, a negative errno value.
It seems Image.Discard() never can have worked as intended, unless the
error was disregarded. Just like Image.Write(), Image.Discard() should
return a tuple of the number of bytes discarded and an error.

rbd_get_features() returns a uint64_t with the features that are set in
the image. That means combining (with logical OR) features should result
in a uint64 too. Marking all features explicitly uint64 makes it easier
and cleaner to set/test features.

Keeping the _test.go code in the same package allows for the testing
of private functions. AFAWK it is more conventional as well.

We recently created errors in the rbd that match the golang convention
but left aliases for external code. Switch the test code to use the
newer more standard form instead of the "aliases."
Signed-off-by: John Mulligan <jmulligan@redhat.com>
A recent PR added new error values that were similar to the existing
naming convention but were not the normal go convention. Change all the
errors to match typical convention but leave the older names as aliases
such that older code will continue to work (for now).
