This option enables disk cache. If SIZE is 0, the disk cache is
disabled. This feature caches the downloaded data in memory, which
grows to at most SIZE bytes. The cache storage is created for aria2
instance and shared by all downloads. The one advantage of the disk
cache is reduce the disk seek time because the data is written in
larger unit and it is reordered by the offset of the file. If the
underlying file is heavily fragmented it is not the case.
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.
If true is given to --deferred-input option, aria2 does not read all
URIs and options from file specified by -i option at startup, but it
reads one by one when it needs later. This may reduce memory usage if
input file contains a lot of URIs to download. If false is given,
aria2 reads all URIs and options at startup. This option defaults to
false.
Added --download-result=OPT option. This option changes the way
"Download Results" is formatted. If OPT is 'default', print GID,
status, average download speed and path/URI. If multiple files are
involved, path/URI of first requested file is printed and remaining
ones are omitted. If OPT is 'full', print GID, status, average
download speed, percentage of progress and path/URI. The percentage of
progress and path/URI are printed for each requested file in each row.
In MinGW32 build, global::cout is WinConsoleFile. When outputing to
console, it uses WriteConsoleW, so Unicode characters are written.
Fixed memory leak in WChar<->MultiByte conversion functions. The
portion of code which uses std::cout is rewritten to use global::cout.
--enable-rpc and --rpc-* option instead.
--enable-xml-rpc and --xml-rpc-* option can be used but warning
message will be shown. The help tag #xml-rpc was replaced with #rpc.
The method signature is aria2.removeDownloadResult(gid). This method
removes completed/error/removed download denoted by gid from
memory. This method returns "OK" for success.
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.
Added --max-download-result=NUM option. This option sets maximum
number of download result kept in memory. The download results are
completed/error/ removed downloads. The download results are
stored in FIFO queue and it can store at most NUM download
results. When queue is full and new download result is created,
oldest download result is removed from the front of the queue and
new one is pushed to the back. Setting big number in this option
may result high memory consumption after thousands of
downloads. Specifying 0 means no download result is kept. Default
value is 1000.

the function unnecessarily.

Added changePosition XML-RPC method. It takes 3 parameters: gid,
pos and how. This method changes the position of download denoted
by gid. If how is POS_SET, it moves the download to a position
relative to the beginning of the queue. If how is POS_CUR, it
moves the download to a position relative to the current
position. If how is POS_END, it moves the download to a position
relative to the end of the queue. If the destination position is
less than 0 or beyond the end of the queue, it moves the download
to the beginning or the end of the queue respectively. Returns
the destination position.
