* Moved DoutCurlEasy and DoutCurlEasyEntering from aicurl.cpp
to aicurl.h and renamed them to DoutCurl and DoutCurlEntering
respectively.
* Moved the callback functions from aicurl.cpp to aicurlthread.cpp.
* In CurlEasyRequest, renamed timeout_timings to print_curl_timings
and mTimeoutLowercaseHostname to mLowercaseHostname.
* Put all remaining CurlEasyRequest::mTimeout* variables and
timeout_* methods in curlthread::HTTPTimeout, stripping them
of said prefix, and moved the definition to aicurlprivate.h.
Added a ThreadSafeCurlEasyRequest* member and a get_lockobj()
method so to that class so we can still use DoutCurl /
DoutCurlEntering. timeout_add_easy_request was removed completely
and reimplemented as the constructor of HTTPTimeout.
timeout_has_stalled was renamed to HTTPTimeout::has_stalled,
but also reimplemented as CurlEasyRequest::has_stalled.
* CurlEasyRequest::mRequestFinalized was removed and it's
functionality taken over by CurlEasyRequest::mTimeoutPolicy.
* Fixed the indentation of struct Stats, class CurlEasyHandle
and class CurlEasyRequest.
* Added CurlEasyRequest::set_timeout_opts
* Added CurlSocketInfo::mTimeout (LLPointer<HTTPTimeout>).
* mUploadFinished is now reset in HTTPTimeout::data_received,
this was needed because "HEAD /something" header-only
messages triggered upload_finished (unlike "GET ..."),
and in combination with redirection that caused an assert.
Use the better understandable alias CURLOPT_HTTPHEADER in debug output
Bug fix - finally!
This fixes a bug I've been looking for a week.
By accidently calling get_clock_count() for the mTimeoutLowSpeedClock
'event', the time difference 'now' - 'event' becomes negative, which
should be impossible; the result being that timeout_low_speed
stalled for 24 seconds while looping over the full 32 bit. That in
turn made SSL handshakes of libcurl fail, which seemed to be
impossible since the calls to libcurl had not changed!
* Remove progress meter call back, use read/write/header callbacks instead.
* Don't use timeout_lowspeed for ReplyDelay, instead use:
* Add timeout stuff to the main loop (CurlEasyRequest::mTimeoutStalled).
This patch fixes a few things compared to the previous version.
More things need to be fixed.
Introduces AIHTTPTimeoutPolicy objects which do not just
specify a single "timeout" in seconds, but a plethora of
timings related to the life cycle of the average HTTP
transaction.
This knowledge is that moved to the Responder being
used instead of floating constants hardcoded in the
callers of http requests. This assumes that the same
timeout policy is wanted for each transaction that
uses the same Responder, which can be enforced is needed.
I added a AIHTTPTimeoutPolicy for EVERY responder,
only to make it easier later to tune timeout values
and/or to get feedback about which responder runs
into HTTP errors in debug output (especially time outs),
so that they can be tuned later. If we already understood
exactly what we were doing then most responders could
have been left alone and just return the default timeout
policy: by far most timeout policies are just a copy
of the default policy, currently.
This commit is not finished... It's a work in progress
(viewer runs fine with it though).
