aria2 is a multi-protocol & multi-source, cross platform download utility. The supported protocols are HTTP(S), FTP, BitTorrent, Metalink. It can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth.
aria2 1.18.7 ============ Release Note ------------ This release fixes regression which makes 100% CPU utilization in multi-file torrent download with -V option. It also fixes build error on big endian platforms. Changes ------- * Fixed segfault unsupported encodings Patch from diadistis * Fix regression 100% CPU utility when -V is used and download is multi-file bittorrent downloads. This is regression of a3426821c8a7f9cf8d80a81726157d4eb844f661 * Fix compile error on big endian platform aria2 1.18.6 ============ Release Note ------------ This release fixes several bugs reported in github issues and adds a feature to make RPC authentication more resilient to certain attacks. New option --pause-metadata is added. The explanation is a bit log, so check the changelog and manual. The session is now only saved if there are changes from the last saved state. From this release, MinGW32 build uses Windows native TLS implementation and no longer use OpenSSL library. Changes ------- * Disard cache when checking checksum This will slow down checksum checking but does not thrash cache. * Compat with libuv 0.11 (Unstable) Fixes #241 * Drop WinMessageDigestImpl. The algorithms the `CryptProv` on Windows supports does not currently include SHA-224, so there is a "dark spot" in this implementation. Also on Win XP < SP3, most of the SHA-2 family is not actually supported. All other implementation provide support for MD5, SHA-1 and all of the SHA-2 family, hence drop the incomplete WinMessageDigest implementation in favor of any other supported implementation (at least the internal implementation is always available at compile-time). * Add --pause-metadata option This option pauses downloads created as a result of metadata download. There are 3 types of metadata downloads in aria2: (1) downloading .torrent file. (2) downloading torrent metadata using magnet link. (3) downloading metalink file. These metadata downloads will generate downloads using their metadata. This option pauses these subsequent downloads. * Improve compiler/platform/libs information in logs Add and use usedCompilerAndPlatform(). This adds compiler information to INFO logs and the --version output, and may be helpful when trying to diagnose/reproduce user-reported problems. Also make INFO logs include usedLibs() output. Closes #235 * Fix use-after-free on exit with multi-file torrent download + DHT DefaultPieceStorage may be referenced by one of DHT task (e.g., DHTPeerLookupTask), after RequestGroup was deleted, and even after RequestGroupMan was deleted. DefaultPieceStorage has a reference to MultiDiskAdaptor which calls RequestGroupMan object on destruction. So when DHT task is destroyed, DefaultPieceStorage is destroyed, which in turn destroys MultiDiskAdaptor. DHT task is destroyed after RequestGroupMan was destroyed, MultiDiskAdaptor will use now freed RequestGroupMan object, this is use-after-free. * Fix bug that zero length file is not opened when flushing cache This bug was only seen when MultiDiskAdaptor was used. * Support PREF_DIR change for Metalink files Reworked previous commit adeead6f0396e2f8551d1182972e277728fd6c8b, and now support changing PREF_DIR for Metalink downloads. * Fix assertion failure when dir option of paused HTTP/FTP download is changed When the directory is changed via aria2.changeOption RPC method, we directly change first FileEntry's path using FileEntry::setPath(). If there is no PREF_OUT option is given, basically file name is unknown, so we just set empty string and let the next run determine the correct file name and new directory is applied there. But previous code does not reset length property of FileEntry, so the unexpected code path is taken when unpaused and its path expects path is not empty string. This commit fixes this issue by setting length to 0 using FileEntry::setLength(). * Save session only when there is change since the last serialization This is a slight optimization not to cause useless disk access. This only applies to saving session automatically (see --save-session-interval). aria2.saveSession and serialization at the end of the session are always performed as before. When serialization, we first check that whether there is any change since the last serialization. To do this, we first calculate hash value of serialized content without writing into file. Then compare this value to the value of last serialization. If they do not match, perform serialization. * Fix (unknown length) downloads larger than 2GiB Closes #215 * Fix F_PREALLOC based allocation on some OSX versions * Use index.html as filename for conditional-get when file is missing in URI Previously we disabled conditional-get if file part is missing in URI. But we use constant string "index.html" in this case, so we can do the same to determine the modification time. In this patch, if we have file part in URI, we are not going to set absolute file path in FileEntry, since it prevents content-disposition from working. * Always add README.html to dist_doc_DATA rst2html is required to produce README.html from README.rst. We include generated README.html to distribution. And rst2html is not required when compiling sources in distribution and always README.html is available. * Validate token using PBKDF2-HMAC-SHA1. This change should make token validation more resilient to: - timing attacks (constant time array compare) - brute-force/dictionary attacks (PBKDF2) Closes #220 * Add --disable-websocket configure option * mingw32: Enable wintls and compile with GMP By enabling wintls, we can use Windows certificate store to validate server's certificate. Previously, we built windows build using openssl and since we don't bundle CA certificates, aria2 fails to validate server's certificate unless user setups their CA certificates. GMP provides fast big integer calculations, whic is used in BitTorrent encryption. * AppleTLS: Enable BEAST mitigations in ST Only available in 10.9+, but since we might be building on a previous version but running on 10.9+, always try to set the option. * WinTLS: Accept chains with no revocation information. This is kind what browser do anyway (IE, Firefox, Chrome tested), what AppleTLS does, what GnuTLS does and what OpenSSL does. Actually, most browsers will also be OK with the CRL/OCSP provider being offline. WinTLS will still fail in that case. Should revocation information be available in the trust chain (CRL or OCSP) the certificate still will be checked! "Real" CAs, aka. those provided by the OS or system CA bundle, usually provide revocation information and are thus still checked. It should be mostly (only?) custom (organization) CAs that lack revocation information, but those users might want to use aria2 in their intranets and VPNs anyway ;) See #217 * Fix GnuTLS 2.x compatiblity Closes GH-216 * AppleTLS: Use newer, non-deprecated API in 10.8+ aria2 1.18.5 ============ Release Note ------------ This release fixes BitTorrent download failure on Mingw build. Changes ------- * Ignore error when setting DSCP value Setting DSCP is additional feature and failure to enable it should not abort download entirely. This change fixes the bug that windows build does not perform bittorrent downloads. aria2 1.18.4 ============ Release Note ------------ This release adds new RPC authorization mechanism using --rpc-secret option. The existing --rpc-user and --rpc-passwd options are now deprecated, and all applications using RPC API is strongly encouraged to migrate to the new mechanism. See RPC INTERFACE section in aria2 manual page for the details. The new RPC method, aria2.saveSession, was added, which tells aria2 server to save session file immediately. There are several enhancements and bug fixes. See the changes for the details. Changes ------- * Added support for RPC channel encryption in aria2rpc Patch from David Macek * Add aria2.saveSession RPC method This method saves the current session to a file specified by --save-session option. This method returns "OK" if it succeeds. * Add numStoppedTotal key to aria2.getGlobalStat() RPC method response It shows the number of stopped downloads in the current session and not capped by --max-download-result option. On the other hand, the existing numStopped key also shows the number of stopped downloads, but it is capped by --max-download-result option. * Better handling of 30x HTTP status codes Reference: http://greenbytes.de/tech/tc/httpredirects/ * Implement new RPC authorization using --rpc-secret option Add future deprecation warning to --rpc-user and --rpc-passwd. Warn if neither --rpc-secret nor a combination of --rpc-user/rpc-passwd is set. * Add --enable-color option to enable/disable terminal color output * Add DSCP support * gnutls: Don't fail handshake if returned error is not fatal * Add workaround GnuTLS bug with OCSP status extension and non-blocking socket GnuTLS version 3.1.3 - 3.1.18 and 3.2.0 - 3.2.8, inclusive, has this bug. For these versions, we disable OCSP status extension. * Make GnuTLS log level dependent on the aria2 ones aria2 1.18.3 ============ Release Note ------------ This release fixes the bug which may cause assertion failure after multi-file downloads (e.g., multi-file metalink or torrent) are performed several times due to the bad handling of --bt-max-open-files option. Changes ------- * Fix crash if unpause failed before assigning BtProgressInfoFile object * Enable and check PIE in makerelease-osx * Fix bug that numOpenFile_ is not reduced when MultiDiskAdaptor is deleted This bug caused assertion error in RequestGroupMan::ensureMaxOpenFileLimit aria2 1.18.2 ============ Release Note ------------ This release fixes the wrong handling of return value of fork(), which leads to high CPU usage. The progress readout has some color output. Mingw32 build now receives colorized output. Mingw32 build now can read unicode command-line arguments. The build script of OSX was rewritten. The --bt-max-open-files now limits the number of opened file globally for multi-file downloads instead of per download basis. Changes ------- * Remove the outdated, broken build_osx_release.sh * Initial revision of the a new OSX release Makefile * Allow using libgmp with AppleTLS/WinTLS * Fix crash when metaurl contains unsupported URI or text * Fix bad fork() return value handling * Use some colors in progress reports (where available) * Implement basic color support for the Windows console Only \033[*m (SGR) is supported, with a 16+16 color terminal. * AppleTLS: Implement PKCS12 loading. * Limit number of opened file globally with --bt-max-open-files option 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. * Don't fail multiple concurrent dl same file if auto-file-renaming is enabled * mingw32: Use CommandLineToArgvW() and GetCommandLineW() to read cmd-line args This change enables aria2 to read unicode characters in command-line. aria2 1.18.1 ============ Release Note ------------ This release fixes the percent-encoding bug which affects file name encodings. It adds PKCS12 support in certificate import. It also adds experimental internal implementation of message digest functions, ARC4 cipher and bignum. It means that no external libraries are required to build BitTorrent support, but this feature is still marked as experimental. This release also fixes the android build with NDK r9. Changes ------- * LibsslTLSContext: Remove weak cipher suite * AppleTLS: Enable --certificate * util::percentEncodeMini: Fix regression bug removed unsignedness srange-based for around std::string is convenient but several functions depend unsigned char for correctness and readability. * Log exception; throw error if loading private key and/or certificate failed * Provide internal ARC4 implementation Now you can build bittorrent support without without external libraries, meaning you can skip libnettle, libgmp, libgcrypt, GnuTLS and OpenSSL on OSX (for now). * Internal implementation of DHKeyExchange Reusing a bignum (well, unsigned very-long) implementation I had lying around for years and just cleaned up a bit and brought to C++11 land. It might not be the most performant implementation, but it shoud be fast enough for our purposes and will go a long way of removing gcrypt, nettle, gmp, openssl dependencies when using AppleTLS and WinTLS (upcoming). * PKCS12 support in --certificate and --rpc-certificate options. * Add --disable-ssl configure option * Add internal md5 and sha1 message digests * Fix AppleMessageDigestImpl use with large data * Set old cookie's creation-time to new cookie on replacement As described in http://tools.ietf.org/html/rfc6265#section-5.3 * Fix link error with Android NDK r9 Since Android ndk r9, __set_errno is deprecated. It is now defined as inline function in errno.h. The syscall assembly calls __set_errno, but since libc.so does not export it, the link fails. To workaround this, replace all occurrences of __set_errno with a2_set_errno and define it as normal C function. aria2 1.18.0 ============ Release Note ------------ This release changes the default disk cache size to 16 MiB. To change the default size, --with-disk-cache configure option was added. Now used URIs are also saved by --save-session option. The control file is now always saved if --force-save is given. The ctrl-c handling on Mingw build was improved. The internal intl library is no longer supplied. From this release, C++11 compiler is required to build aria2 executable. For gcc, at least 4.6.3 is required. Changes ------- * Use AM subdir-objects Doing so in AM_INIT_AUTOMAKE seems to be the most compatible way of doing so. Closes GH-120 * AM_SILENT_RULES([yes]) with backwards-compatiblity Supported since automake-1.11. There is no point in having the very verbose compile stuff running about, which cannot even silenced properly with `make -s` by default. Otherwise, `make V=1` or `--disable-silent-rules` are your friends * Fix automake-1.14 am_aux_dir AC_USE_SYSTEM_EXTENSIONS will cause AC_PROG_CC, which is overridden by automake-1.14, which will then init (part) of automake, in particular am_aux_dir expansion, which in turn relies on ac_aux-dir, which is not initialized at this point, and thus: certain doom (or fun, depending on your POV and mood :p) Hence call AC_USE_SYSTEM_EXTENSIONS only after AM_INIT_AUTOMAKE. This, of course, caused a lot of related macro shuffling. Tested against automake-1.10 (OSX Lion/XCode version) and automake-1.14 (homebrew version) * Require external gettext for --enable-nls And stop using the internal flavor with ./intl * Make AX_CXX_COMPILE_STDCXX_11 test for -stdlib=libc++ via std::shared_ptr The clang shipped with OSX XCode and clangs not build enabling libcpp, will default to the libstdc++ headers and lib installed on the system. In the OSX case, that libstdc++ is the one bundles with gcc-4.2, which is far too old to provide all required C++11 types, such as std::shared_ptr. Hence, the C++11 check should try to compile a program with a C++11 type and try -stdlib=libc++ if the default lib fails to compile said program. * Make the configure check for C++11 compiler mandatory Remove stray "dnl", so that mandatory actually works with (my) autoreconf. * Always build doc/manual-src Should sphinx-build be not available AND the man file not be prsent, then just "touch" it into existence (and warn about that) * Win: Use SetConsoleCtrlHandler for SIGINT/SIGTERM * Implement a simple resource lock (threading) In this initial implementation Locks are no-ops on platforms other than Windows. * Check for sphinx-build during configure * Add --with-disk-cache configure option Enables packagers more fine grained control over the default value without having to mess with config files. See GH-115 * Change defaults: Enable 16M disk cache by default. * Always save control file if --force-save is given * Set log level DEBUG for unittests * Check that C++ compiler supports override keyword If the compiler supports override, define CXX11_OVERRIDE as override, otherwise define it as empty. Use CXX11_OVERRIDE instead of override. * AppleTLS: Fix MessageDigestImpl * AppleTLS: Fix session CFRelease stuff * Use AX_CXX_COMPILE_STDCXX_11 macro to detect C++0x/C++11 support in compiler * Require -std=c++11 and use std::shared_ptr instead of SharedHandle * Join URI on redirect * Send HAVE message to the peer which the piece is downloaded from Historically, aria2 did not send HAVE message to the peer which the piece is coming from, thinking it is obvious that the peer knows we have the piece. But it is not obvious if one piece is download from more than 1 peers (e.g., end game mode). So it is better to send HAVE to all peers connected. * Improvements to --follow-torrent=false documentation. Patch from gt * SessionSerializer: Truly unique URIs Before, only spent uris where sanitized not to be contained within remaining uris. Change this so that each uri in the union(remaining,spent) get saved once at most. The order of the uris will won't be changed, with remaining uris going first followed by spent uris. Also avoid copying the uri std::strings around during dupe checking, usually resulting in better performance regarding CPU and space. * Make getOption RPC method return option for stopped downloads * SessionSerializer: Save spent URIs as well as remaining ones
