* prevent connection write collisions
When multiple calls are made on the same connection, it's possible for
the writes to collide with each other. This adds a write mutex when
communicating with the libvirt daemon.
libvirt follows a convention where structure types used in its API are
named "remote_nonnull_domain", and optional values for those structures
are called "remote_domain". The generator was translating these into go
names like "NonnullDomain" and "Domain". In go this seems unnatural, and
doesn't match the way the pre-generator version of go-libvirt named
things. So this commit changes the names: "remote_nonnull_domain" will
now be "Domain" in go; "remote_domain" will be "OptDomain". This pattern
is applied to all types.
- Bump the minimum libvirt version from 1.2.2 to 1.2.12, because
virDomainDefineXMLFlags wasn't introduced until that version.
- Use the correct format for the generated file notice, so that golint
ignores the generated files.
- Update libvirt.go so that all libvirt calls now go through the
generated routines.
- Remove some libvirt routines that had the same name as generated ones,
leave the rest as convenience routines.
- Fix the handling of Optional-values (the declarations of which in the
.x file look like pointers)
The generated wrappers have an argument for every field in their "Args"
struct, and return everything in their "Ret" struct (these structs are
defined in the protocol file, and identified by procedure name).
Marshaling and unmarshaling is handled inside the generated procedures.
- Add a yacc-based parser and a hand-written lexer to read the
remote_protocol.x file from libvirt's sources.
- Use the new parser to generate the constants used to communicate with
libvirt.
* Handle TypedParamStrings
Add handling for TypedParamStrings, which are different from the other
TypedParam... types in that the decoded value is variable-sized.
* Add Get/SetBlockIoTune to go-libvirt API.
This adds two libvirt entry points to the go-libvirt API:
virDomainSetBlockIoTune and virDomainGetBlockIoTune. These can be used
to control block device throttling for a VM.
This updates the project README, removing the pre-production warning
and adding a note about the libvirt project's feelings surrounding
direct interaction with the RPC interface.
This adds a new method, Capabilities(), which returns an XML
definition of the hypervisor's system capabilities, much like
`virsh capabilities`.
I've only included integration tests for these two methods due to the
large amount of data returned by the capabilities call.
This adds support for dumping a domain's XML definition, akin to `virsh
dumpxml <domain>`. The returned data is quite large so I've included an
integration test rather than adding a huge blob of hex to `libvirttest`.
This modifies the travis-ci configuration to build and install libvirt
1.2.2 and 2.3.0 for integration testing. Simple integration tests have
been included for Connect() and Disconnect().
