This change changes the behavior of --bt-max-open-files. Previously,
it specifies the maximum number of opened files for each multi-file
download. Since it is more useful to limit the number globally, the
option now specifies the global limit. This change suggests that
aria2.changeOption() method now ignores --bt-max-open-files and
aria2.changeGlobalOption now reads it and dynamically change the
limit.
--save-session-interval option saves error/unfinished downloads to a
file specified by --save-session option every SEC seconds. If 0 is
given, file will be saved only when aria2 exits.
This option sets GID manually. aria2 identifies each download by the
ID called GID. The GID must be hex string of 16 characters, thus
[0-9a-zA-Z] are allowed and leading zeros must not be stripped. The
GID all 0 is reserved and must not be used. The GID must be unique,
otherwise error is reported and the download is not added. This
option is useful when restoring the sessions saved using
--save-session option. If this option is not used, new GID is
generated by aria2.
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.
--force-save option saves download with --save-session option even if
the download is completed or removed. This may be useful to save
BitTorrent seeding which is recognized as completed state. The
default value is false.
If true is given, which is default, save the uploaded torrent or
metalink metadata in the directory specified by --dir option. The
filename consists of SHA1-hash hex string of metadata plus
extension. For torrent, the extension is '.torrent'. For metalink, it
is '.meta4'. If false is given to this option, the downloads added by
aria2.addTorrent or aria2.addMetalink will not be saved by
--save-session option.
To enable RPC over SSL/TLS, specify server certificate and private key
using --rpc-certificate and --rpc-private-key options and enable
--rpc-secure option. After the encryption is enabled, use https and
wss scheme to access RPC server.
--file-allocation option can now take new value 'trunc'. 'trunc' uses
ftruncate() system call or platform-specific counterpart to truncate a
file to a specified length.
Removes the unselected files when download is completed in
BitTorrent. To selecting files, use --select-file option. If it is not
used, all files are assumed to be selected. Please use this option
with care because it will actually remove files from your disk.
This option is default to false.
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.
This feature stops application when process PID is not running. This
is useful if aria2 process is forked from a parent process. The parent
process can fork aria2 with its own pid and when parent process exits
for some reason, aria2 can detect it and shutdown itself.
The code which detects whether or not given process PID is running is
contributed by Emmanuel Engelhart.
This option sets a piece length for HTTP/FTP downloads. This is the
boundary when aria2 splits a file. All splits occur at multiple of
this length. This option will be ignored in BitTorrent downloads. It
will be also ignored if Metalink file contains piece hashes.
Added --checksum=TYPE=DIGEST option. This option sets checksum. TYPE
is hash type. The supported hash type is listed in "Hash Algorithms"
in "aria2c -v". DIGEST is hex digest. For example, setting sha-1
digest looks like this: sha-1=0192ba11326fe2298c8cb4de616f4d4140213838
This option applies only to HTTP(S)/FTP downloads.
Added --hash-check-only opiton. If true is given, after hash check
using --check-integrity option, abort download whether or not download
is complete. The default value is 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.
This option pauses download after added. This option is effective only
when --enable-rpc=true is given. When --save-session option is used
and there are paused downloads, they are saved with --pause=true so
that it will become paused state when the session is recovered.
This option truncates console readout to fit in a single line. This
is default. Give false value to this option to tell aria2 not to
truncate console readout.
This option specifies piece selection algorithm used in HTTP/FTP
download. Piece means fixed length segment which is downloaded in
parallel in segmented download. If 'default' is given, aria2 selects
piece so that it reduces the number of establishing connection. This
is reasonable default behaviour because establishing connection is an
expensive operation. If 'inorder' is given, aria2 selects piece which
has minimum index. Index=0 means first of the file. This will be
useful to view movie while downloading it. --enable-http-pipelining
option may be useful to reduce reconnection overhead. Please note
that aria2 honors --min-split-size option, so it will be necessary to
specify a reasonable value to --min-split-size option.
--metalink-uri option specifies base URI to resolve relative URI in
metalink file stored in local disk. If URI points to a directory, URI
must end with '/'.
--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.
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.
This option was once existed in aria2 but erased on 2009-09-20. Now
it is resurrected once again. We choose 2 as default value, but there
is no good theory behind it. Now we retry HTTP download when remote
server returns 503 Service Unavailable if --retry-wait > 0. We also
added error code 29: HTTP_SERVICE_UNAVAILABLE.
Made --allow-overwrite, --allow-piece-length-change,
--realtime-chunk-checksum and --bt-require-crypto take optional
argument. Fixed usage doc for --metalink-enable-unique-protocol.

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.

Added --bt-tracker and --bt-exclude-tracker option. In
--bt-tracker option, you can specify comma separated list of
additional BitTorrent tracker's announce URI. These URIs are not
affected by --bt-exclude-tracker option because they are added
after URIs in --bt-exclude-tracker option are removed. In
--bt-exclude-tracker option, you can specify comma separated list
of BitTorrent tracker's announce URI to remove. You can use
special value '*' which matches all URIs, thus removes all
announce URIs. When specifying '*' in shell command-line, don't
forget to escape or quote it.

Added --on-bt-download-complete=COMMAND option. For BitTorrent, a
command specified in --on-download-complete is called when
download completes and seeding is over. On the other hand, this
option set the command to be executed when download completes but
before seeding.

Added --conditional-get option. Download file only when the local
file is older than remote file. This function only works with
HTTP(S) downloads only. It does not work if file size is specified
in Metalink. It also ignores Content-Disposition header. If a
control file exists, this option will be ignored. This function
uses If-Modified-Since header to get only newer file
conditionally. When getting modification time of local file, it
uses user supplied filename(see --out option) or filename part in
URI if --out is not specified.

Added --min-split-size=SIZE option. aria2 does not split less
than 2*SIZE byte range. For example, let's consider downloading
20MiB file. If SIZE is 10M, aria2 can split file into 2 range
[0-10MiB) and [10MiB-20MiB) and download it using 2 sources(if
--split >= 2, of course). If SIZE is 15M, since 2*15M > 20MiB,
aria2 does not split file and download it using 1 source.

Added --max-connection-per-server=NUM option. The default value of
NUM is 1. This option limits the number of connections allowed to
one server for each download. This means when NUM is 2 and 1 URI
is provided, even if you specified -s 5, aria2 establishes 2
connections. Default value of -j option is changed from 5 to 2.

Added aria2.pause and aria2.unpause XML-RPC method. aria2.pause
pauses the download denoted by gid. gid is of type string. The
status of paused download becomes "paused" and the download is
placed on the first position of waiting queue. As long as the
status is "paused", the download is not started. To change status
to "waiting", use aria2.unpause method. This method returns GID of
paused download. aria2.unpause changes the status of the download
denoted by gid from "paused" to "waiting". This makes the download
eligible to restart. gid is of type string. This method returns
GID of unpaused download.

Don't send "Accept: default, gzip" by default. This is because
some server responds with "Content-Encoding: gzip" for files which
itself is gzipped file and aria2 inflates them. This is a problem
if user don't want to inflate the file. Apparently this is server
configuration error, but I cannot do anything about this. So turn
this off. Added --http-accept-gzip option. If true is given to
this option, aria2 sends 'Accept: deflate, gzip' request header
and inflates response if remote server responds with
'Content-Encoding: gzip' or 'Content-Encoding: deflate'. This
indicates we removed extension tgz hack in order not to inflate
files with tgz extensions.

Documented --always-resume and --max-resume-failure-tries option
and exit status 8 in man page. Fixed typo.
* doc/aria2c.1.txt
* src/OptionHandlerFactory.cc
Added --always-resume and --max-resume-failure-tries option. If
--always-resume=false is given, when all given URIs does not
support resume or aria2 encounters N URIs which does not support
resume
(N is the value specified using --max-resume-failure-tries
option), aria2 download file from scratch. The default behavior
is --always-resume=true, which means if all URIs do not support
resume, download fails. I think this is OK because user normally
don't like to see that partially downloaded file is
overwritten(this is particularly true if file size is big). This
option is useful when aria2 is used as download backend and
graceful falling back to overwritten behavior is preferable.
Added exit status value 8, which means download failed because
server did not support resume.

Added --remove-control-file option. This option removes control
file(*.aria2 file) before download. Using with
--allow-overwrite=true, download always starts from scratch. This
will be useful for users behind proxy server which disables
resume. For such proxy user, -C1 is also recommended for Metalink
downloads to avoid establishing unnecessary connections.

prints sizes and speed in human readable format(e.g., 1.2Ki,
3.4Mi) in the console readout. The default value is true and it
looks exactly the same as aria2-1.8.0. So the 'new feature'
appears when false is given. In this case, sizes and speed are
printed without in bytes. No Ki, Mi units conversion is used.

try to download first and last pieces of each file first. The
argument can contain 2 keywords:head and tail. To include both
keywords, they must be separated by comma. These keywords can take
one parameter, SIZE. For example , if head=SIZE is specified,
pieces in the range of first SIZE bytes of each file get higher
priority. tail=SIZE means the range of last SIZE bytes of each
file. SIZE can include K or M(1K = 1024, 1M = 1024K).
