The asynchronous listener had no reliable way to access HTTP result and
headers from the callbacks. As the callbacks are triggered
asynchronously, they can be run after the request has carried on and,
for example, followed an HTTP redirect, clearing its internal state.
The HeadersReceived callback now passes a reference to BUrlResult for
the request. There are two cases:
- Synchronous listener: passes a reference to the request's results
directly
- Asynchronous listener: archives a copy of the result into the
notification message, and passes a reference to the unarchived copy.
Unfortunately this comes with several ABI and API breakages:
- Change to the prototype of HeadersReceived()
- Change to the class hierarchy of BUrlResult (implements BArchivable)
All users of HTTP requests will need to be updated if they implemented
in HeadersReceived or used BUrlResult.
Integrated the classes in the Network Kit (libbnetapi.so). Only the foundation
classed BUrl, BUrlContext, BNetworkCookie, BNetworkCookieJar and the private
HttpTime code is currently compiled. The BUrlProtocol currently contains some
misplaced BUrlProtocolHttp specific stuff, and the HTTP stuff itself has a
dependency on libcrypto and should live in an add-on instead. I've sprinkled
some TODOs in the code, and I've done some renaming compared to the last
version of the GSoC patch. Any help to bring this further along is appreciated.
