* Added framing::BodyHolder:Alan Conway2007-11-221-1/+1
| | | | | | | | | | | | | | - Uniform holder for all body types, replaces MethodHolder. - Uses in_place constructors to avoid avoid body copy. framing::AMQFrame: - Holds body in heap-allocated intrusive_ptr<BodyHolder> - Uses in_place constructors to avoid avoid body copy. Removed/downgraded to TODO many redundant FIXME comments. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@597513 13f79535-47bb-0310-9956-ffa450edef68
* Session resume support in client & broker: Client can resume a sessionAlan Conway2007-10-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | after voluntary suspend() or network failure. Frames lost in network failure are automatically re-transmitted for transparent re-connection. client::Session improvements: - Locking to avoid races between network & user threads. - Replaced client::StateManager with sys::StateMonitor - avoid heap allocation. qpid::Exception clean up: - use QPID_MSG consistently to format exception messages. - throw typed exceptions (in reply_exceptions.h) for AMQP exceptions. - re-throw correct typed exception on client for exceptions from broker. - Removed QpidError.h rubygen/templates/constants.rb: - constants.h: Added FOO_CLASS_ID and FOO_BAR_METHOD_ID constants. - reply_constants.h: Added throwReplyException(code, text) log::Logger: - Fixed shutdown race in Statement::~Initializer() git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@588761 13f79535-47bb-0310-9956-ffa450edef68
* * Summary: new Frame type to replace AMQFrame. Instead of holdingAlan Conway2007-08-071-0/+92
a shared_ptr to a heap-allocated AMQBody subclass, it holds the body in-line in a boost::variant of all the concrete AMQBody subclasses. Actually there are nested variants, the compiler does not cope well with a single variant of 130-some types. Creating, encoding and decoding a local Frame doess 0 heap allocation apart from that done by the concrete AMQBody::encode/decode - e.g. method bodies with std::string fields. for method bodies All variants contain type boost::blank. This guarantees 0 heap alloocation by the variant and represents the "uninitialized" state. variant.h provides NoBlankVisitor to help write visitors for variants containing blank. * src/qpid/framing/MethodHolder.h, .cpp: Holds a variant containing a method body. * src/qpid/framing/Frame.h, .cpp: New Frame holds body in a variant rather than via heap allocation. * src/qpid/framing/variant.h: Utilities for using boost::variant. * src/qpid/framing/amqp_types.h: Added FrameType typedef. * src/qpid/framing/AMQMethodBody.h: Friends with MethodHolder. * src/Makefile.am: - Improved ruby generation rule. - Run method_variants template. - Added new source files - Pre-compiled header rule for method_variants.h * rubygen/templates/method_variants.rb: Generate variants to hold methods of each class, and MethodVariant to hold all the class variants. * rubygen/cppgen.rb: variant, tuple methods. * MethodBodyClass.h.tmpl: Added default constructor to method bodies. * amqpgen.rb (AmqpRoot::merge): fix bug in merge. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@563683 13f79535-47bb-0310-9956-ffa450edef68
