aria2 1.2.0
===========
Release Note
------------
This release adds the AdaptiveURISelector from Mandriva developers and
changes the default value of --proxy-method option from 'tunnel' to
'get'. The several BitTorrent options were added: limiting the number
of peers, choosing port randomly from specified range, a toggle to
seed after successful hash check and specifying IP address to report
to a tracker. Hash checking is now done sequentially rather than
simultaneously. HTTP Authorization was also refined so that now
authorization header is sent to the server only when it is
requested(there are some exceptions, see Changes below). aria2 now
returns exit code depending on the last error. All exit codes are
documented in man page. This release also adds experimental built-in
HTTP server which provides the current download progress in plain
html.
Changes
-------
* Changed the default value of --proxy-method option from 'tunnel' to
'get'. Use 'tunnel' for HTTPS regardless of --proxy-method option.
* Added --bt-external-ip option. You can specify the external IP
address to report to a BitTorrent tracker. Although this function is
named 'external', it can accept any kind of IP addresses.
* Applied AdaptiveURISelector-timeout patch from Pascal Rigaux at
Mandriva. I modified the patch: make RequestGroup have the timeout
value and AdaptiveURISelector directly modifies that value.
* Use LongestSequencePieceSelector for HTTP/FTP/BitTorrent integrated
downloads. This PieceSelector subclass finds the longest continuous
sequence in the available missing pieces and selects the last index
of such sequence. This makes HTTP/FTP connections less interrupted
by the pieces obtained by BitTorrent peers.
* Fixed the bug that the average speed is wrong in http/ftp/BitTorrent
integrated download. Only the download bytes in BitTorrent were
considered.
* Choose port for BitTorrent/DHT randomly from the specified range.
REQUEST#2543518
* Send HTTP Authorization header only if it is requested by the
server(response 401). There are some exceptions. The authorization
header for proxy is always sent if it is available without request
by the server. If username/password is specified in the URI, it is
immediately sent to the server without request by the server.
Implements REQUEST#2540844.
* Remove leading "--" from help keyword and a substring after "=" from
help keyword, so that one can query options by '-h--max-' or
'-hmax-peers=10'.
* Added experimental built-in HTTP server. Currently, when a client
accesses to the server, it responds with the current download
progress. By default, it is disabled. To enable the server, give
--enable-http-server option. To change the default port number for
the server to listen to, use --http-server-listen-port option. The
response HTML is very simple and refreshes it self each 1 second.
Because of this refresh, you see flicker in normal web browser such
as Firefox. I recommend to use console-based browser such as
elinks, w3m. To connect to the server, run 'elinks
http://localhost:6800/' while running aria2. Please replace port
number '6800'(which is default) with your preference.
* Made (piece) hash check sequential for each RequestGroup because
simultaneous hash check is slower than sequential execution.
* Added --bt-max-peers option to specify the maximum number of peers
per torrent. 0 means unlimited number of peers. REQUEST#2451382
* Added --bt-hash-check-seed option. If true is given to this option,
after hash check using --check-integrity option and file is
complete, continue to seed file. If you want to check file and
download it only when it is damaged or incomplete, set this option
to false. This option has effect only on BitTorrent download. The
default value is true(This is the same behavior with the previous
release).
* Made the max value of split option unlimited. REQUEST#2496748
* Added --event-poll option to select the method for polling events.
The available methods are "select" and "epoll". "epoll" is
available on Linux only. The earlier release has the compile
option to choose from these methods.
* Included RecoverableException.h from main.cc. BUG#2498160
* Applied exit-status patch from Pascal Rigaux at Mandriva. aria2 now
returns last error encountered in the HTTP/FTP downloads as a exit
status value. If all downloads finished successfully, aria2 returns
0. The error code is defined in src/DownloadResult.h. The error
occurred in the download currently in progress is not reported as a
last error. If no error has encountered but there are in progress
or waiting downloads, aria2 returns 7.
* Applied AdaptiveURISelector patch from Aurelien Lefebvre. This
patch adds AdaptiveURISelector, which selects one of the bests
mirrors for first and reserved connections. For supplementary
ones, it returns mirrors which has not been tested yet, and if
each of them already tested, returns mirrors which has to be
tested again. Otherwise, it doesn't return anymore mirrors.
* Fixed unit test error in HTTPResponseTest. PATCH#2485509
