aria2 1.10.0
============
This release adds an option to limit the number of connections to the
same host in each download. aria2 now chooses server which is least
used in aria2c instance. This release also adds Chromium cookie
support and HTTP only conditional download support which is download
file only when the local file is older than remote file. aria2 now
can handle %2F in FTP URI properly. HTTP/1.1 chunked decoder was
fixed. For Linux, aria2 uses fallocate by default if it is usable.
aria2 1.9.5
============
This release fixes the bug that causes corrupted file. It also fixes
assertion error in DefaultPeerStorage class. Now aria2 doesn't reset
referer to "" on redirect. log and log-level option can be used
in aria2.changeGlobalOption XML-RPC method. This means you can
dynamically start or stop logging and change log file and log level.
aria2 1.9.4
============
This release fixes the bug that connection reuse on FTP does not work
if FTP server changes root directory based on account. It also fixes
the bug that reading Metalink document from pipe (-M- option) does not
work when aria2 is built with expat or old libxml2(2.7.6 or
earlier). Now aria2 does not emit error if given Metalink document is
empty(no file element). The response of aria2.tellStopped XML-RPC
method now has more information: totalLength, completedLength,
uploadLength, bitfield and so on.
aria2 1.9.3
============
This release fixes the bug that aria2 cuts filename after ';' if
filename in Content-Disposition header includes ';'. It also fixes
the bug that name attribute of file element in Metalink file is not
properly sanitized.
aria2 1.9.2
============
This release adds kqueue, port_associate/port_getn and poll() support
for socket event notification to eliminate 1024 file descriptor
limitation of select() call. The bug that aria2.unpause and
aria2.unpauseAll XML-RPC method fail when -s1 is given in command-line
argument was fixed.
aria2 1.9.1
============
This release adds the ability to save unfinished downloads as text
file. aria2 can read the file with -i option on restart. This
release also adds the ability to download file from scratch when aria2
sees resume is not supported by remote server. This feature is
disabled by default. See --always-resume option for
details. --no-proxy option accepts IPv4 network address with CIDR
block. aria2 now doesn't send "Accept-Encoding: deflate, gzip" by
default. --http-accept-gzip option was added to toggle this behavior.
aria2 now treats lines starting "#" in -i list as comments. Several
XML-RPC methods were added: aria2.pause, aria2.unpause,
aria2.shutdown, and their families. The new exist status code '8' was
added. The bug that makes aria2 hang when system time changes while
aria2 is running was fixed on MinGW32, Mac OS X and the system which
has clock_gettime(). Several other bugs also have been fixed.
aria2 1.9.0
============
This release adds Metalink4 support and BitTorrent Local Peer
Discovery. aria2.changeUri XML-RPC method was added. It enables you
to add/remove URIs to existing downloads dynamically. The user and
password for proxy server now can be specified in command-line
separately. We refactored the code based on profiler results, so
aria2 now runs more efficiently than ever. Russian and Simplified
Chinese translation were updated.
aria2 1.8.3
============
This release fixes the bug that --file-allocation=falloc doesn't work
with single file download. It also fixes the bug that the return value
of aria2 is unreliable if error occurs before download begins. When
custom request headers specified by --header option now override
built-in headers if they have same name.
aria2 1.8.2
============
s release fixes the bug that causes segmentation fault with
--max-file-not-found option involved. Now aria2 can handle redirected
URI which is not properly percent encoded. In MinGW32 build, console
readout is now always cut by 80 characters. 'bittorrent' key is added
to the response of tellStatus XML-RPC method. The associated value of
the key is a struct and contains data retrieved from .torrent file,
such as name, announce-list, comment, etc.
aria2 1.8.1
============
This release fixes the bug that causes segmentation fault if unknown
options exist in aria2.conf file and user cannot include empty line in
aria2.conf.
Following new command line options are added: --http-no-cache,
--bt-metadata-only and --human-readable option. --dir option now
treats "" as ".". --all-proxy, --http-proxy, --https-proxy and
--ftp-proxy option accept empty string "". When "" is given, it
erases previously defined proxy.
aria2.getSessionInfo XML-RPC method was added. aria2.tellWaiting and
aria2.tellStopped XML-RPC method accept a negative integer as
offset. For example, in aria2.tellWaiting, 'offset' == -1 points last
download in the waiting queue and 'offset' == -2 points the download
before the last download, and so on. 'dir' and 'files' key were added
to the response struct of aria2.tellStatus XML-RPC method. The value
associated with 'files' key is the list of files. Its element is the
same struct used in aria2.getFiles XML-RPC method. 'uris' key was
added to the response struct of aria2.getFiles XML-RPC method. The
value associated with 'uris' key is the list of URIs. Its element is
the same struct used in aria2.getUris XML-RPC method. aria2 now
returns gzip compressed XML-RPC response if XML-RPC client accepts
gzip content encoding.
aria2 1.8.0
============
This release fixes the bug that configure script fails to detect
GnuTLS library if --without-sqlite3 is given. The new XML-RPC methods
are added: aria2.getOption, aria2.getGetGlobalOption,
aria2.changePosition, aria2.tellStopped and system.multicall.
--bt-save-metadata option is added. This option saves metadata as
.torrent file. This option has effect only when BitTorrent Magnet URI
is used.
aria2-1.7.2
============
This release fixes the bug that aria2 listens wrong port in
BitTorrent/FTP downloads when --interface option is used. If
--metalink-file='-' is given, aria2 now reads Metalink file from
stdin. Magnet URI is printed in the output of -S option. DHT is
now enabled by default. DHT doesn't start while aria2 only handles
HTTP/FTP downloads. On the first torrent download begins, aria2
initiates DHT functionality. After that, DHT runs until aria2 exits
aria2 1.7.1
============
This release fixes the bug that --bt-prioritize-piece=tail is not
working.
aria2 1.7.0
============
This release adds BitTorrent Magnet URI support. 3 options were
added: the ability to bind to particular interface, disabling IPv6 and
prioritizing piece in BitTorrent downloads. In configure script, if
--with-PACKAGE and --enable-FEATURE are given but PACKAGE is missing
in the system or FEATURE cannot be enabled in the current
configuration, the script now prints error message and exits.
--http-auth-scheme option was removed since it is useless. Updated
Russian, Ukrainian, German and French translations.
aria2 1.6.3
============
This release fixes reported bugs and updates Polish, Catalan, French,
Italian, Russian and Japanese translations.
aria2 1.6.2
============
This release fixes segmentation fault error if URI to download
contains printf format string and logging is enabled. The build
scripts are updated to automake 1.11 and autoconf 2.64. Updated
Ukrainian translation.
aria2 1.6.1
============
This release fixes memory leak in HTTP/FTP download. It also fixes the
bug that the option values changed by XML-RPC changeOption and
changeGlobalOption methods are cleared. Now User-agent and Peer ID
include version number. Updated Simplified Chinese translations.
aria2 1.6.0
============
This release changes the default behavior of XML-RPC server. Now it
listens only on local loopback interface by default for security
reasons. If you want to connect to aria2c from remote hosts, use
--xml-rpc-listen-all option. The XML-RPC client sample script written
in Ruby are now included in the archive under doc/xmlrpc directory.
These scripts are licensed under MIT License. The help category tags
are now start "#" to distinguish them from keyword search. Several
help category tags were added: #xml-rpc, #cookie, #hook and #file.
--retry-wait option was removed because it doesn't work properly under
the architecture. Updated Bulgarian, Russian, Slovak and Japanese
translations.
aria2 1.5.2
============
This release fixes the bug that when the first attempt to establishing
connection fails, aria2 don't try to connect another address and a
download immediately fails. -S output was enhanced: exact file size
is now printed. For -S with torrent file, meta data such as comment,
comment.utf-8, created by and creation date are now printed. Ukrainian
and Russian translations were updated.
aria2 1.5.1
============
This release fixes linker error in unit test code on 32bit
systems. The unit test failure on mingw32 was also fixed. The file I/O
error handlings were written.
aria2 1.5.0
============
This release adds WEB-Seeding support for multi-file torrent.
--bt-stop-timeout option was added. This function stops BitTorrent
download if the download speed is 0 in consecutive given seconds.
aria2 now tries all resolved addresses to connect to remote servers in
HTTP(S)/FTP until it gets connected. For XML-RPC, two new methods
were added: aria2.tellWaiting and aria2.getVersion. The error code is
available in the response of aria2.tellStatus methods for
stopped/completed downloads. --use-head is now disabled by default
since using HEAD request causes problems in some web sites. The
behavior of -D option has been changed: If -D is specified, the
current working directory is set to / and stdin, stdout and stderr are
redirected to /dev/null. This release fixes the bug that zombie
processes are created when commands specified in --on-download-*
options are executed and the bug that http-user, http-passwd, ftp-user
and ftp-passwd are ignored when they are given via XML-RPC. Updated
Russian, Italian, Danish, Bulgarian, Japanese and Ukrainian
translations.
aria2 1.4.1
============
This release fixes the compile error without the development package
of c-ares library installed. The compile error under MinGW was fixed.
aria2.tellStatus XML-RPC method now returns "uploadLength" and
"numSeeders". Ukrainian translation was updated.
aria2 1.4.0
============
This release adds XML-RPC interface and the ability to run command
when download started/stopped and the ability to save cookies. The
current XML-RPC API allows users to add http(s)/ftp/torrent/Metalink
download and change options dynamically. The APIs such as reporting
download progress, file paths, URIs and peer information are also
available. For complete API specification, see XML-RPC INTERFACE
section in man page and
http://apps.sourceforge.net/trac/aria2/wiki/XmlrpcInterface. The
console readout was slightly updated and now includes the number of
seeders the client has connected to. Slovak translation was
added. Ukrainian and Brazilian Portuguese translation were updated.
aria2 1.3.3
============
This release fixes the bug that --check-integrity option doesn't work
properly if a file including last piece is missing and increases
internal receive buffer for FTP in order to receive big banner.
Ukrainian, Russian and Simplified Chinese translations were updated.
aria2 1.3.2
============
This release fixes the bug that prevents certain BitTorrent downloads
from finishing and possible segmentation fault when gzip decoding is
involved and infinite loop bug if last "0" chunk-size marker is not
received in chunked encoding transfer. aria2 now supports
WEB-Seeding(HTTP-Seeding) for single file torrent. Ukrainian
translation was updated.
aria2 1.3.1
============
This release fixes the bug that aria2 wrongly determines that
specified share ratio is reached because of miscalculation of upload
bytes and the bug that upload limit exceeds the value specified in
--seed-ratio option depending on the timing of the execution of
SeedCheckCommand.
aria2 1.3.0
============
This release adds the ability to specify the output filenames in
BitTorrent downloads and the option to limit overall download speed
and dry run mode which just checks the availability of the remote
file. -i list option can now take new options: select-file and
index-out. The default behavior of sending HTTP Authorization header
is reverted back to version 1.1.2 style. The bug in
AdaptiveURISelector was fixed. You can now seed read-only files in
BitTorrent. --file-allocation option can take new parameter
'falloc'. If it is given and you are using newer file systems such as
ext4, btrfs or xfs, large(few GiB) files are allocated almost
instantly. The performance optimization has been done and aria2 runs
more efficiently.
Indonesian, Russian, Italian, Ukrainian, Simplified Chinese, Japanese,
Spanish and Norwegian Nynorsk translations were updated.
timeval's seconds are "long" rather than "time_t". Passing these
seconds to localtime_r() breaks on 64-bit platforms where those types
aren't the same. Fixes PR 40323 from Andreas Burghardt.
PKGREVISION++ as a precaution, since I patched the source.
- Added Serbian, Vietnamese, and Traditional Chinese translations.
Updated French, Simplified Chinese, and Japanese Translations.
- Added length equality test to operator== to drop a piece message
whose length does not match to the requested one.
- Fixed the bug that aria2 aborts when a request larger than 16KiB is
recieved. In this fix, if a request larger than 16KiB length is
received, aria2 disconnects the peer.
- Updated man page. Changed doctype of aria2c.1.html to manpage in order
not to replace '--' with em dash character.
- Added --auto-save-interval=SEC option. A control file(*.aria2) is saved
every SEC seconds.
- Added --dht-file-path option to change the path to dht.dat, which is a
serialized DHT routing table.
- Fixed the bug that last character in URI is not encoded.
- Fixed the bug that referer header field contains fragment. Now Request
class removes fragment part of URI and encodes it in Request::setUri()
and setReferer().
Added Turkish translation. Updated German and Russian translations.
If an error occurred with a URI, remove identical URI from remaining
URI list because it is likely that same error occurred in the end and it
is waste of time.
Added -lrt to LIBCARES_LIBS if -lrt is needed to link program with
-lcares.
Moved implementation to SimpleRandomizer.cc from SimpleRandomizer.h.
Added return value of getpid() to argument of srand() to achieve more
randomized value.
Contact tracker frequently when the number of connections are 0 and
download is not finished yet.
Moved threshold values to UTPexExtensionMessage.
Added _incoming member to Peer class and made it true if the peer
initiated connection. Don't add those peer to UTPex message.
If extended handshake is received, assign _incoming to false.
Fixed infinite loop bug in FTP when SIZE command failed.
Made files whose name ends with ".gz", ".tgz" not inflated by Content
Encoding Decoder. Removed size threshold for turning off on the fly
inflation because resulting file may or may not be inflated depending
on the file size and I think it is not expected by users.
This change fixes segmentation fault when Metalink file contains gzipped
file and its filesize is provided.
Fixed chunk checksum validation cannot detect trailing garbage data.
BUG#2074141
significant feature enhancements; it also now builds on OpenSolaris
(tested with NexentaOS by development community).
I urge all users to upgrade.
A _partial_ list of changes:
- Added and/or updated Danish, Greek, Spanish, Catalan,
Norwegian Nynorsk, Bulgarian, French, Catalan, and Japanese
translations.
- Man page fixes.
- Fixed: numCommand is less than the value specified in -C option.
- Myriad bug fixes.
- Now uses name attribute in Metalink as local filename in
BitTorrent downloads. BUG#2033999
- Fixed memory leaks in test code.
- Fixed wrong argument passing to BitfieldMan::isBitSet()
- Initialized _directIOAllowed
- Fixed memory leak in gzip decoder and metalink parser state
machine.
- Plug many other memory leaks and fix unmatch malloc/free calls.
- Removed max chunk size check. This change fixes BUG#2040169
- Fixed the bug that causes segmentaion fault when resuming
download using metalink without size tag. Reproducible only
using HTTP URI.
- Removed writable check when socket's send buffer is full in
BitTorrent downloads to lower CPU usage.
- Fixed broken gzip inflation.
Turn off segmented downloading if gzip content is smaller than
or equal to 1MiB and inflate the data on the fly, because HTTP
response header doesn't contain the length of inflated
file we can't determin where the chunk of data should be written.
On the other hand, if gzip content is larger than 1MB, then
turn off on the fly inflation, because some servers returns
"content-type: gzip" for *.tgz, *.gz files.
- Added gzip decompressor via libz.
- Cache last calculated average download/upload speed.
- Supported absolute/relative path in Location header field.
- Use File::exists() instead of File::isFile() to allow non-
regular file such as block special files.
- Added a message "aria2 doesn't verify signature" to log message
when signature file is saved.
- Added the ability to save signature when download is completed
if signature is available. The filename of signature file is
the path to download file followed by ".sig". If it already
exists, then signature will not be saved.
- Improve accuracy of documentation and rename some options to be
more descriptive of their functions/purposes.
- Added the ability to retrieve signature from Metalink file.
A retrieved signature is stored in Signature class and it is
held by DownloadContext class. Note that aria2 doesn't
verify signature.
- Added --bt-seed option. If --bt-seed=true is given at the
command-line, aria2 seeds previously downloaded files
without validating piece hashes.
- Fixed the compile error on Nexenta OS(GNU/Solaris OS).
(Don't define `struct addrinfo' when __sun is defined)
- Fixed the bug that UTF-8 encoded URL is not URL-encoded
- Properly differentiate between ftp errors and actual zero-byte
files (now supports ftp servers which do not recognize SIZE
raw command).
plus some new features.
==========================================================================
Changes:
aria2-0.14.0+1
* Fixed the code that refers static member variable from
non-static context.
Notes:
This release adds epoll support for linux and the ability to
limiting the number of files to be opened to support more than
1024 files in multi file torrent.
Several bugs in BitTorrent downloads are fixed.
From this release, aria2 downloads a file using 5 connections
in HTTP/FTP by default and the behavior of -s option has
changed. See the project web page for more details.
Changes:
aria2-0.14.0
* Changed -s options behavior. Now it means the number of connections
made simultaneously in each http/ftp download. If 1 URL is specified,
the behavior is the same with old implementation. If -s N is given
and more than N URLs are specified, first N URLs are used and
remaining URLs are used for backup. If less than N URLs are specified,
some of URLs are used more than once so that totally N connections are
made simultaneously.
* Changed default value of -s option from 1 to 5.
Also max value of -s option is changed from 5 to 16.
* Reduced CPU usage on high load.
* Added epoll support.
* Fixed compile error on debian etch. BUG#1980766
* Added --bt-request-peer-speed-limit=SPEED option.
In BitTorrent downloads, if the download speed is lower than SPEED,
aria2 initiates and accepts connections ignoring max peer cap.
* Reduced read operation for hash calculation.
* Fixed the bug that aria2 cannot respond bttrack's nat check properly.
* Fixed the bug that HTTP downloads don't start with old libraries.
* Fixed the bug that aria2 aborts when a path to a directory is given in
command-line.
* Added --bt-max-open-files option, which specifies maximum number of
files toopen in each BitTorrent download. REQUEST#1811507
* Create only requested files and files which shares a piece with
requested file in multi-torrent downloads. Directory structures are
also created in the same rule.
* When there is not enough space in disk, aria2 prints error in the
console and cancels that download. BUG#1640332
and feature enhancements--way too many for this commit message.
While here, deprecate aria2-metalink option. Aria2 now supports
building with libexpat, so we do that by default now.
Some of the more significant changes:
-------------------------------------
* Fixed compile error without gnutls/libgcrypt/libgpg-error and openSSL
installed. Fixed compilation on: x84-64 platform, Mac OSX, g++-4.3,
and without c-ares/ares.
* Added Simplified Chinese translation. Also updated the following
translations: Polish, Dutch, German, Thai, Indonesian,
Norwegian Nynorsk, Hungarian, Finnish, Hebrew.
* Changed inactive connection timeout to 120.
To accept more mulually interested peers, disconnect peer when there
is no interest between us after certain time passed.
Lengthened DNS timeout to 30. I think old value '10' will be a
little bit short when some DNS servers are offline and several
DNS servers are tried. It should be configured by
command-line option.
* Fixed the bug that prevents aria2 from stopping other than by pressing
Ctrl-C in BitTorrent download. It is reproducible using --seed-time
option. aria2 doesn't stop even after --seed-time is satisfied and
continues to output blank lines in the console.
* Added Message Stream Encryption(MSE) support.
Currently, aria2 accepts incoming connections with Obfuscation Header
and legacy BitTorrent Header and establishes connections with
Obfuscation Header first and if failed then retry with legacy
BitTorrent header. If plain text and ARC4 is provided, aria2 always
choose ARC4. The new option to change the default behavior is planned.
For tracker extension, "supportcrypto=1" is added statically.
* Added the ability to load nodes from torrent file. These nodes are
added to the routing table when downloading that torrent.
* Added the ability to stop aria2 itself when given time has passed
from start. Use --stop option to specify time in minutes.
When 0 is given, this feature is disabled.
before calling RequestGroupMan::fillRequestGroupFromReserver().
Without this modification, the result list shows "ERR" when aria2 is
stopped by --stop option. It should be "INPR".
Bootstrap through node added by port message.
Currently bootstrap is executed if the number of buckets in routing
table is 1.
* Added DHT functionality, compatible with mainline.
DHT is disabled by default. To enable it, give --enable-dht to aria2c.
You may need to specify entry point to DHT network using
--dht-entry-point. DHT uses UDP port to listen incoming message.
Use --dht-listen-port to specify port number. Make sure that your
firewall configuration can pass through UDP traffic to the port.
The routing table is saved in $HOME/.aria2/dht.dat. Request peers though
DHT only when download hasn't finished.
should automagically handle the features stuff (or at least other packages
that I look at don't seem to need this if they use autoconf, haven't looked
extensively, though). This release brings lots of bug fixes. Among
them are:
2008-01-10 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Fixed the bug that EX_TOO_LONG_PAYLOAD exception is thrown if just
payload length(4bytes) are received. This happens because
lenbufLength
is not updated in this particular case and successive call of
receiveMessage() overwrites payload length with bytes recieved which
are payload body.
2007-12-22 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Fixed the bug that causes aria2 not to finish download. BUG#1855875.
I could reproduce this bug in following procedure:
1. Stop the download at the very beginning(1% or 100KB downloaded).
2. Restart aria2.
3. You see the download stopped around 99%.
If timeout is reached, then _nextCommand is unused and it may
contains
segments and they won't be canceled. Actually, timeout is not needed
here because if the server dropped connection, then retry is made.
2007-12-22 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Fixed the bug that returns incomplete data when it contains null
character. A convenient constructor was also added.
2007-12-15 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Fixed the bug that prevents aria2 from loading cookie file when
expire
value is greater than 2^31-1. BUG#1851066
2007-12-14 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Fixed possible memory leak when an exception is thrown.
2007-12-10 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Fixed the bug: only first announce URL is tried in AnnounceTier,
in stopped and completed event.
2007-12-09 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Removed unnecessary string copy. Updated doc and corrected
indentation.
<nbconfig/config.h>. Partial list of changes:
2007-12-09 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>
Removed unnecessary string copy. Updated doc and corrected indentation.
* src/Base64.cc
Fixed compilation warnings

translations. Many thanks to translators.
* po/{ca,es,it,pt_BR,sv}.po
* po/LINGUAS
Fixed the bug#1845750; CTRL+C does not stop torrent.
aria2 repeatedly sends stopped request when tracker returns error code.
Added a message when ctrl-c is hit.
Now second ctrl-c is also handled in signal handler.
Changed Direct/IO enable/disable procesure in file allocation routine.
Disable directIO if offset is not multiple of 512.
(~SingleFileAllocationIterator): Removed a call to disableDirectIO.
* src/MultiFileAllocationIterator.cc (allocateChunk):
Enable created SingleFileAllocationIterator's directIO.
* src/FileAllocationEntry.cc
(FileAllocationEntry): Enable directIO here.
(~FileAllocationEntry): Disable directIO here.
Fixed the bug: aria2 doesn't utilize fast set index offered by peer.
Rewritten direct I/O support routine
Fixed compile error without message digest support.
Enable direct I/O support in checksum checking.
Added --allow-piece-length-change option.
Fixed: duplicated result entry appears when exception is thrown in
RequestGroup::createInitiateConnectionCommand().
* src/RequestGroupMan.cc (fillRequestGroupFromReserver):
Add RequestGroup to _requestGroup after RequetGroup::
createInitiateConnectionCommand() succeeds.
Externalized message
Forced download abort when received negative response from http/ftp
server.
Added XML2SAXMetalinkProcessor class, which is a lot faster than
the predecessor, Xml2MetalinkParser class.
I tested them against 94KB metalink file with 1234 chunk checksums.
The new one parsed it in 22msec, while it took 6000msec with old one.
Rewritten Base64 class for better performance.
Fixed the bug#1841757: aria2 will connect to server to only get
file size.
Suppressed wrong message when finding PreDownloadHandler
Eliminated g++-4.2 warning
Fixed bug: --check-integrity doesn't work for multi file torrent.
Added direct I/O support. The current implementation uses O_DIRECT,
which is not posix standard and is tested on linux 2.6.21.
Currently only file allocation uses direct I/O.
