There are too many dependencies to mention individually.
Please see the dependencies of individual Debian packages and the contents
setup.py files throughout the Rok repository for the initial list of
We will record individual changes in the set of dependencies in forthcoming versions.
- VMware: The semantics of the current implementation of
Snapshotdeviate from the VASA 2.0 specification and will be fixed in the next version.
- VMware: The VASA provider does not return proper SOAP Faults on error conditions.
- VMware: The VASA provider does not report metrics properly, including Container size, and free space.
- VMware: The semantics of the current implementation of
- The composer may leak memory after long periods of time, potentially due to allocating but not releasing memory in the case of missing fisks during map requests.
- There is currently no way to enforce a global limit on the memory usage or TCP connections of thrower.
- libpu: On the target side, libpu-managed objects are not garbage-collected when the corresponding nexuses disappear.
- libctrl: The embedded controller has a use-after-free bug for nexuses returned
- libmpath: Mpath will erroneously close a nexus when failing to submit a request
to it because it was full (returned
EAGAIN). It should check if its queue is full, and not consider it for submission instead.
- libmpath: libmpath will not release a nexus from an mpath if this nexus has pending I/O, even when this I/O is not related with said mpath.
- Python: Have the Python bindings return finer-grained errors as subclasses
PUErrorexceptions. Currently, the GW assumes specific type of errors when a generic
PUErrorexception is thrown.
- Python: Have the Python bindings return finer-grained errors as subclasses of
