-----------------------------------
Summary: c_glib: Support server implementation
Key: THRIFT-2709
URL: https://issues.apache.org/jira/browse/THRIFT-2709
Project: Thrift
Issue Type: Improvement
Components: C glib - Compiler, C glib - Library
Affects Versions: 0.9.1
Environment: Fedora 20 64-bit on x86_64
Reporter: Simon South
Priority: Minor
The attached patches modify the C (GLib) compiler and library to add support
for implementing servers.
The changes to the compiler include
* Adding server-generation methods
** {{generate_service_helpers}}, which generates a pair of {{ThriftStruct}}
subclasses for each service method, used to deserialize the method's arguments
and serialize its result
** {{generate_service_handler}}, which generates an abstract base class for a
service's handler implementations
** {{generate_service_processor}}, which generates a service's processor class
* Adding helper methods {{underscores_to_initial_caps}} and
{{property_type_name}} which, respectively, convert an underscore-delimited
name back to camel case and return the GLib type needed to store a Thrift type
as a GObject property
Changes to the library include
* Changing the signature of {{ThriftProcessor.process}} so it returns I/O
errors to its caller
* Adding the {{ThriftDispatchProcessor}} class, ported from the C++
implementation, which subclasses {{ThriftProcessor}} and parses an incoming
method-call message for dispatch by subclasses
* Adding a {{peek}} method to {{ThriftTransport}} and corresponding
implementations in {{ThriftSocket}}, {{ThriftBufferedTransport}} and
{{ThriftFramedTransport}}
* Add {{ThriftBufferedTransportFactory}} and {{ThriftFramedTransportFactory}},
used by the server to wrap a raw {{ThriftTransport}} in the corresponding
subtype
* Changing the signature of {{ThriftServer.server}} so it returns an error
status to its caller, following [GLib's
conventions|https://developer.gnome.org/glib/2.26/glib-Error-Reporting.html#glib-Error-Reporting.description]
* Changing {{ThriftSimpleServer.serve}} so it
** Detects and reports errors encountered during processing
** Uses transports returned by the transport factories instead of the (raw)
transport passed in by the caller
** Uses {{ThriftTransport.peek}} to detect the end of input
** Returns an error status to its caller
