WebSocketSessionMan now implements DownloadEventListener and is added
to Notifier. It becomes member variable of DownloadEngine. The event
constant for download event is defined in aria2.h so that we can add
event callback API later.
The old implementation calculates download/upload statistics for a
RequestGroup by summing up all PeerStat objects. For global
statistics, those are summed together. This clearly incurs runtime
penalty and we introduced some kind of caching which updates
statistics every 250ms but it did not work right.
This change removes all these aggregation code, and instead makes
RequestGroup and RequestGroupMan objects hold NetStat object and
download/upload bytes are directly calculated by thier own NetStat.
This is far more simplar than the old way and less runtime penalty and
brings more accuracy.
Socket::getPeerInfo() may fail if its TCP connection has already
disconnected. In this case, we log this error. The success or failure
of pooling connection should not affect the later execution of the
program.
This option accepts comma separated list of DNS server address used in
asynchronous DNS resolver. Usually asynchronous DNS resolver reads DNS
server addresses from /etc/resolv.conf. When this option is used, it
uses DNS servers specified in this option instead of ones in
/etc/resolv.conf. You can specify both IPv4 and IPv6 address. This
option is useful when the system does not have /etc/resolv.conf and
user does not have the permission to create it.
Inside calculateStatistics(), global::wallclock is used and if
calculateStatistics() is called after waitData(), it may use quite old
global::wallclock value.
DownloadEngine::onEndOfRun() to process RequestGroup objects currently
in-progress.
With this change, --on-download-stop/error/complete hooks are properly
called for in-progress downloads when Ctrl-C is pressed.
Added .cc file for classes/structs that only provided by header
file. Defined non-POD classes' ctor, dtor in .cc file. Moved
implementation code in header file to .cc file for major
classes/strucsts.
Removed SharedHandle::isNull(). Instead we added operator* and
operator unspecified_bool_type. Removed use of WeakHandle and
replaced with raw pointer.
Don't reuse socket which is readable because we assume that if
socket is readable it means peer shutdowns connection and the
socket will receive EOF. Added default timeout value to
DownloadEngine::poolSocket().

Set milliseconds in DownloadEngine::refreshInterval_. Because
there is difference in accuracy between epoll and clock_gettime(),
we set DEFAULT_REFRESH_INTERVAL 900ms just lower than default
timeout 1 sec for epoll. Also set update interval of
ConsoleStatCalc to 900ms by the same reason.

Fixed the bug that connection pooling does not take into account
proxy. This means that when connection A via proxy X is pooled,
it will be wrongly reused in the download using proxy Y.

Fixed the bug that FTP download may fail when control connection
is reused. This happens because FTP server can offer different
root directory for different account. If pooled connections has
different root directory, then download will fail.

Avoid to calculate end() iterator in each loop. std::deque is
particularly slow. Make sure that recalculate end iterator if
element is erased during loop.
Added aria2.getSessionInfo XML-RPC method. This method returns a
struct containing Session ID, which is generated each time when
aria2 is invoked.
