aria2 1.10.7 ============ Release Note ------------ This release fixes the bug that causes memory leak when parsing Metalink document if aria2 is built with expat. It also add several exit status codes to help identify the cause of error. --max-connection-per-server option now works with Metalink. aria2 now passes number of files and file path in addition to gid to command specified in --on-download-* options. MinGW32 build now encodes non-ASCII characters in file path using percent-encoding. With this release, bash_completion file for aria2c is included in the distribution. See doc/bash_completion directory in the archive. Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use -x16 -k1M (see --max-connection-per-server and --min-split-size option in man page). If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * Pass the number of requested files and file path to the command specified --{bt-}on-download-* option. * Throw exception when unrecognized URI, bad Metalink or bad .torrent file are given in command-line and exits with status non-zero. * Added aria2c bash_completion. * Added more error code values. * For MINGW32 build, percent-encode non-ASCII characters in filename. * Made --continue, --daemon, --no-conf, --no-netrc, --show-files, --allow-overwrite, --allow-piece-length-change, --realtime-chunk-checksum and --bt-require-crypto option take optional argument. * Enter 'end game' mode from the beginning when getting torrent metadata for quick data retrieval. * Use --max-connection-per-server option value for Metalink as well * Fixed memory leak with expat. * Added sha-224, sha-384, sha-512 hash function support. aria2 1.10.6 ============ Release Note ------------ This release fixes the bug that downloading files larger than 4GB fails on 32 bit systems. It also fixes the bug that dht.dat file is not saved. The improper use of return value of vsnprintf was fixed, which caused segmentation fault when formatting strings more than 1024 characters long. Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use -x16 -k1M (see --max-connection-per-server and --min-split-size option in man page). If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * Fixed the bug that downloading > 4GB file fails on 32bit systems. * Fixed improper use of vsnprintf in StringFormat which is mainly used for formatting strings of exception message. The actual bug reported by the user was that aria2 emitted segmentation fault error when very long URI(few thousands characters long) was given. * Fixed the bug that dht.dat file could not be saved. This is because a directory denoting temporary file path is wrongly created and thus aria2 fails to open the file as regular file. aria2 1.10.5 ============ Release Note ------------ This release fixes the bug that file allocation is enabled in HTTP even if --file-allocation=none is specified. Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use -x16 -k1M (see --max-connection-per-server and --min-split-size option in man page). If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * 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(). * Fixed the bug that file allocation is enabled in HTTP even if --file-allocation=none is specified. aria2 1.10.4 ============ Release Note ------------ This release fixes the bug that aria2 hangs when FTP server does not send '226 Transfer Complete' message and the bug that the time used in file allocation is taken into account when calculating download speed. Non UTF-8 filenames are now percent-encoded. The comments and name in .torrent file in XML-RPC response are also percent-encoded if they are not UTF-8. Compile error on OpenBSD4.7(i386) was fixed. A warning message when CA certificates are not imported is not printed in console. It is shown when certificate verification error is actually occurred. Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use -x16 -k1M (see --max-connection-per-server and --min-split-size option in man page). If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * Updated Russian, Simplified Chinese and French translation. Thanks to all translators. * Use RFC1123 date format for creation date of .torrent file printed using -S. * Rewritten Cookie class and Cookie parser based on http://tools.ietf.org/html/draft-ietf-httpstate-cookie-15 * Use inet_ntoa if inet_ntop is not available. Since inet_ntoa does not handle IPv6 address, IPv6 support is limited in this case. Fixed unit test error under mingw32. * Don't show warning message in console when CA certificates are not imported. --ca-certificate and --check-certificate option were mentioned in the error message displayed when certificate verification failed. * Print message when performing slow file allocation at first time. * Fixed compile error on OpenBSD4.7(i386). * Execute 5 DHT tasks concurrently in each task queue. * Fixed the bug that FtpFinishDownloadCommand does not handle timeout. This means it waits for the remote server to send "226 Transfer Complete" message *without* its own timeout until the remote server shutdowns connection(we can detect EOF in this case). * Rewritten util::escapePath(). Now it does not replace bad chars with '_':it performs percent-encoding against them. util::fixTaintedBasename() now replaces "/" with "%2F". Added 0x7f as bad chars in util::detectDirTraversal(). * Non-UTF8 filenames are now percent-encoded. For example, filename for http://example.org/%90%A2%8AE will be %90%A2%8AE because it is Shift_JIS. The comments and name in .torrent file in XML-RPC response are percent-encoded if they are not UTF-8. * Reset download start time of PeerStat because it is started before file allocation begins. Without reset, we have incorrect download time and aria2 wrongly determines that download speed is too low if --lowest-speed-limit is used. * Added keys parameter to aria2.tellStatus, aria2.tellActive, aria2.tellWaiting and aria2.tellStopped XML-RPC method. 'keys' is array of string. If it is specified, the response contains only keys in 'keys' array. If 'keys' is empty or not specified, the response contains all keys. This is useful when you just want specific keys and avoid unnecessary transfers. For example, aria2.tellStatus("1", ["gid", "status"]) returns 'gid' and 'status' key. aria2 1.10.3 ============ Release Note ------------ This release adds short option -x for --max-connection-per-server option and -k for --min-split-size option. It also adds --max-download-result=NUM option. This option sets maximum number of download result kept in memory and the default value is 1000. --max-connection-per-server now accepts up to 16. '@' character is now allowed in username embedded in URI. This release fixes the bug that aria2 reports error and exits with non-zero status when file is already downloaded and checksum is available. Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use -x16 -k1M (see --max-connection-per-server and --min-split-size option in man page). If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * Replaced V_TRUE with A2_V_TRUE. Replaced V_FALSE with A2_V_FALSE. * Added short option -k for --min-split-size option and -x for --max-connection-per-server option. Raised maximum value of --max-connection-per-server up to 16. * 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. * Check hash(hash for entire file, not piece hash) if --check-integrity option is given and file is downloaded(determined by file length). If it fails, re-download file. * Mark cached IP address bad on timeout to allow aria2 to renew IP address cache. * Fixed the bug that aria2 reports error and exits with non-zero status when file is already downloaded. * Allow '@' in username and password embedded in URI. It should be percent-encoded but many people use their mail address as an username and forget about PE. * Data from remote server in HTTP/FTP download are now written to the disk(or memory) through StreamFilter. Decoding chunked and gziped streams are done cascading StreamFilter. Removed inefficient 1byte read code. aria2 1.10.2 ============ Release Note ------------ This release fixes the bug that prevents HTTP redirect from working when multiple files are downloaded from same host at the same time. For netrc, aria2 now performs domain match if machine name defined in .netrc starts with ".". Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use --max-connection-per-server=4 --min-split-size=1M. If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * In .netrc file, if machine name starts ".", aria2 performs domain match instead of exact match. * Fixed the bug which prevents HTTP redirection from working when downloading multiple files from same host at the same time. aria2 1.10.1 ============ Release Note ------------ This release adds IPv6 support for FTP, BitTorrent and BitTorrent DHT. For FTP, EPSV and EPRT command support was added. Enabling IPv6 DHT requires several options, so please check out the usage example in man page or wiki usage example page. By default, the asynchronous DNS resolver does not handle IPv6 address. To work with IPv6 address, use --enable-async-dns6 option. aria2 now listens on both IPv4 and IPv6 socket for BitTorrent, its DHT and XML-RPC. aria2 uses same port for both IPv4 and IPv6. The ability to add/remove BitTorrent tracker announce URI was added. The link error for FallocFileAllocationIterator was fixed. Please note that since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB segment size restriction. So whatever value you specify using -s option, it uses 1 connection per host. To make it behave like 1.9.x, use --max-connection-per-server=4 --min-split-size=1M. If you specify multiple hosts, aria2 will use all of them and open multiple connections. Changes ------- * Enter end game mode as soon as all pieces are assigned to peers to avoid substantial slow down at the very last stage of download. * Set max outstanding request size of BitTorrent download to 100. Set stepping to 6. * 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 bt-tracker and bt-exclude-tracker to -i list option. * Listen both IPv4 and IPv6 for BitTorrent protocol. * Listen both IPv4 and IPv6 for xml-rpc request. * Added IPv6 DHT. Added --dht-entry-porint6, --dht-file-path6, --dht-listen-addr6 and --enable-dht6 option. IPv6 DHT is disabled by default. To use IPv6 DHT, you need to use --enable-dht6 and specify a global unicast address to --dht-listen-addr6. IPv6 DHT is highly experimental. * Added support for peers6 key in tracker response. Added added6, added6.f and dropped6 in ut_pex. * Add only gracefully disconnected peer to ut_pex dropped list. Add incoming dropped list to PeerStorage. * Don't use pre-calculate hash value when end-game mode. Throw exception if bad piece is received. * Added bittorrent::packcompact() which replaces bittorrent::createcompact() and supports IPv6 addresses. Rewritten bittorrent::unpackcompact() and bittorrent::extractPeer() to support IPv6 addresses. Fixed added.f flags in ut_pex. * Added --enable-async-dns6 option. This option enables IPv6 name resolution in asynchronous DNS resolver. This option will be ignored when --async-dns=false. * Use hostname of original URI when counting hostname in inFlightRequest. * Fixed the bug that AdaptiveFileAllocationIterator::getCurrentLength() does not return updated allocated bytes. * Added FTP EPSV and EPRT command support. aria2 issues these commands when address family of local socket is AF_INET6. * Rewritten check for fallocate using AC_COMPILE_IFELSE. * Fixed the bug that HAVE_SOME_FALLOCATE gets undefined if fallocate is not available even if posix_fallocate is available. This causes FallocFileAllocationIterator.cc is out of compile targets and linker error. aria2 1.10.0 ============ Release Note ------------ 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. Changes ------- * Metadata download may take very long time. If URIs are available, give up metadata download in at most 30 seconds. * 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. * FeedbackURISelector now tries to select URI whose host is least used in aria2 globally. * 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. * Set end byte in Range header if start byte > 0 to get more chance to pool socket. * Fixed ChunkedDecoder. It does not read trailer and final CRLF. * Send each CWD component of FTP URI in separate CWD command as described in RFC1738. * Fixed the bug that aria2 cannot handle %2F in FTP URI properly. If directory component starts with %2F which percent-encode of '/', client should issue CWD to absolute path, but aria2 does not do that. It just issues relative path and download fails. * Added Chromium/Google Chrome Cookies file support. Thanks to gotrunks for original patch. * When allocating disk space, for Linux system with fallocate() system call, first check file system supports fallocate. This just run fallocate with small chunk and see it succeeds or fails. If it succeeds, use fallocate() to allocate entire file otherwise fall back to traditional slower method: writing zeros. This behavior is enabled in --file-allocation=prealloc, so this is enabled by default for most modern Linux.
