configure: Use pkg-config to find libs whenever possible
Use pkg-config to find cppunit, libxml2 and expat. All those libraries provide pkg-config files, and in all of those cases the pkg-config macro is superior to the custom macros used currently.
The advantages of pkg-config files include:
Explicit static linking support via --static. Currently, e.g. xml2-config --libs' prints all libraries needed for static linking when doing dynamic linking unnecessary, resulting in unnecessary direct deps.
Better cross-build support. You don't have to build the additional *-config tools for target.
Better multilib support. Per-ABI pkgconfig directories are commonly supported while packages usually fail to look for per-CHOST *-config variants.
Better override support. The current macros allow little to no result overrides, the pkg-config macros let you pass FOO_CFLAGS and FOO_LIBS manually.
Cleaner version checks. The code used in libxml.m4 is really creepy.
Patch from Michał Górny
WinTLS: Rewrite writeData
We re-wrote WinTLSSession::writeData. The major points are:
Buffer is now preallocated once handshake is finished. Previously, they are allocated each time when we send one TLS record.
Schannel uses header, body and trailer for each secBuffer. Now we send them off at once using WSASend which is windows counterpart of sendv. Previously, we do memmove if some of them are truncated.
We don't try to send application data in WinTLSSession::closeConnection, since semantically we need same application data used to create TLS record before. Using 0 length data to finish sending buffered data looks like a hack.

New in aria2 1.20.0 Build 1 (Feb 15, 2016)

This release fixes lots of bugs. See the Changes section below.
There are new features in this release. We added "seeder" key in
aria2.tellStatus RPC response. We added system.listMethods RPC method
to return all RPC method supported. We added --max-mmap-limit option
to avoid mmap if total file size is greater than given size.
Changes:
src/WinConsoleFile.cc: fix colour
Set default foreground/background colour correctly
Patch from kwkam
configure.ac: fix autoreconf error
Use m4_ifdef so we do not have to install optional libraries
Patch from kwkam
Don't inherit file descriptor to child process
For non-Mingw32 build, set FD_CLOEXEC to file descriptors which live beyond function scope. For Mingw32 build, just pass false to bInheritHandles parameter of CreateProcessW.
Update Russian version documentation
Patch from ITriskTI
Add "seeder" key to tellStatus RPC response
WinTLS: Fix hang because of buffered received data
WinTLSSession buffers received decrypted data into its own buffer.
If read is requested, it copies the data from its buffer. But if requested buffer size is less than decrypted buffer, some of the data is left in the buffer. Previously, we had no facility to check the existence of this pending data. If this data is the last requested data from remote server, we may end up waiting for read event even if we have already data in our buffer, which may cause hang. This commit fixes this issue by introducing function to return the buffered length in TLSSession. SocketCore also provides the same function, which delegates to TLSSession object.
Add --max-mmap-limit option
Set the maximum file size to enable mmap (see --enable-mmap option). The file size is determined by the sum of all files contained in one download. For example, if a download contains 5 files, then file size is the total size of those files. If file size is strictly greater than the size specified in this option, mmap will be disabled.
mingw: Use SetFileValidData to make --file-allocation=falloc work
Retry with 504 status code
Increase DHT transaction ID from 2 to 4 bytes to avoid conflict
Update wslay
Add --enable-werror option to configure to enable warning flags
Don't modify user variables (e.g., CFLAGS, LIBS, etc)
Improve error message when loading pkcs12 file failed
Updated dependency and source url's
The RaspberryPi Dockerfile had some out-of-date dependency packages and was downloading an outdated aria2 source from Sourceforge, which resulted in a build for version 1.19.0. The new fetch-latest-release-from-GitHub script I've cooked up should always work as long as GitHub doesn't change their API and aria2's platform agnostic releases follow the "{version number}.tar.bz2" naming format.
Patch from c3mb0
Reduce delay in tracker request
We eliminated 1 second delay between completion of name resolution for tracker request and time when it is actually issued. We also elimited 1 second delay after last torrent download exists and it is told to DHTInteractionCommand.
Disable IPv6 on non-async NameResolver if configuration wants
Fix mysterious 1 second delay with async DNS
Fix bug that UDP port was incorrectly used in UDP tracker announce request
Refactor HttpRequest
This also makes comparison performed when replacing builtin header field with user-defined one case-insensitive.
Send Want-Digest as per RFC 3230
Try all found address set to bind sockets with --multiple-interface
Fixes GH-523
Replace sourceforge references with aria2.github.io
Add system.listMethods RPC method
system.listMethods just returns the available RPC method names. It can be executed without secret token, because it just returns the method names, and does not alter anything.
Support content-range from non-compliant server
Reduce UDP tracker request timeout
Apply --retry-wait when retrying after 404
Previously, --retry-wait was not used when retrying after 404 (--max-file-not-found). The retry was done without delay. Also the maximum retry count (--max-retries) was ignored when retrying with 404.
This commit makes --retry-wait apply for retrying with 404 as well. It also combines --max-retries and --max-file-not-found. When retrying with 404, it is counted toward retry count.

New in aria2 1.19.3 Build 1 (Dec 9, 2015)

Changes
Fix bug that pause/unpause seeding torrent prevents new downloads from starting
Previously, with --bt-detach-seed-only, when user issued pause and unpause command to seeding torrent, and it was started again, and it immediately got seeding status, but aria2 did not start new download waiting in the queue. This commit fixes this bug.
Add --bt-enable-hook-after-hash-check option
This option sets flag which allows hook command invocation after hash check (see -V option) in BitTorrent download. By default, when hash check succeeds, the command given by --on-bt-download-complete is executed. To disable this action, give false to this option.
Add --socket-recv-buffer-size option
Set the maximum socket receive buffer in bytes. Specifing 0 will disable this option. This value will be set to socket file descriptor using SO_RCVBUF socket option with setsockopt() call.
Disable --deferred-input when --save-session is used together
With --deferred-input=true, aria2 only reads input file to fill active download slots, while keeping input file open. Meanwhile, --save-session saves all download info inside memory, but this does not take into account of unread item in input file. This will lead to lose input data in saved session file. Also current BufferedFile implementation used to read/write input/output file take a lock on Windows. This effectively prevents session serializer from writing session data to the same file which is still kept open because of --deferred-input. See GH-493
base32: decode lowercased characters as well
This fixes the bug that magnet URI with lowercased btih is treated as malformed.
mingw: Use GetFileSize to get file size
_wstat family does not work with symbolic links. They always returns size 0. To workaround this, we now use GetFileSize to get file size. To do that, we need to first obtain file HANDLE, which is a bit tedious because of the messy interface of CreateFileW, but we have no way to get around it.
Fix bug that file allocation=trunc does not work with Windows symlink
Send the last error message as part of tellStatus RPC response
Patch from Jarda Snajdr
Don't enable mmap if file allocation is disabled
Without file allocation, we cannot map file because file length could be zero.
This could fix bug reported at GH-478
Evict timed out pooled socket periodically
Previously we only scanned pool socket to check they are timed out when we pooled another socket. This means that pooled socket is not closed long time (stays in CLOSE-WAIT state) if we don't pool any more socket. In this commit, we now check pooled socket periodically (30 seconds) to avoid the sockets hanging in CLOSE-WAIT state long time.
Don't write control file if content is not changed from previous one
This is desirable so that we don't have to wake up disk if control file is not changed, and it is not have to be written again. We use the same method (SHA1 hash) to check the content is the same. The limitation is the hash is stored in memory, so we have to write the first time in each session.
Remove content-length and content-range if transfer-encoding is given
Retry after 404 status if --max-file-not-found > 0

New in aria2 1.18.9 Build 1 (Feb 11, 2015)

Changes:
Support HTTP date ending "+0000" as well as "GMT".
Closes GH-330
Revise getRandom facilities
Use one of the following to provide random bytes: - Windows CryptGenRandom - Linux getrandom (syscall interface to urandom, without nasty
corner cases such as file descriptor exhaustion or re-linked /dev/urandom)
std::device_random (C++ random device, which usually will be urandom)
This also equalizes util::getRandom and SimpleRandomizer (the former will now use the latter) instead of having essentially two different PRNG interfaces with potentially different quality.
Closes GH-320
Added debug log of all Metalink URLs with final priorities
Use gcc-4.9 and android-16 API level for android build
Add --bt-force-encryption option
This option requires BitTorrent message payload encryption with arc4. This is a shorthand of --bt-requre-crypto --bt-min-crypto-level=arc4. If true is given, deny legacy BitTorrent handshake and only use Obfuscation handshake and always encrypt message payload. This option defaults to false.
TLS: Fix memory leak with OpenSSL
Based on the patch submitted by midnight2k
Warn about insecure SSL connections.
Fixed GH-313
Add --min-tls-version option
The --min-tls-version option specifies minimum SSL/TLS version to enable. Possible Values: SSLv3, TLSv1, TLSv1.1, TLSv1.2 Default: TLSv1
LibsslTLSContext: Disable SSLv3 and enable ECDHE cipher suites
Add Dockerfile.mingw
Dockerfile.mingw builds aria2 Windows binary. It is probably the easiest way to build the Windows binary.
Fix crash when JSON batch response vector is empty
Fix doc: Wrong rpc secret token prefix
Add --bt-detach-seed-only option
This option excludes seed only downloads when counting concurrent active downloads (-j option). This means that if -j3 is given and this option is turned on and 3 downloads are active and one of those enters seed mode, then it is excluded from active download count (thus it becomes 2), and the next download waiting in queue gets started. But be aware that seeding item is still recognized as active download in RPC method.
mingw: Use MoveFileExW for better atomic move
Work around libintl's vprintf macro messing with OutputFile::vprintf
Fix crash on OSX when proxy is used
Support Adler32 checksum
Adler32 checksum is available for --checksum option and hash element in Metalink files. Currently, we use Adler32 implementation in Zlib.

New in aria2 1.18.6 Build 1 (Jul 14, 2014)

Disard cache when checking checksum:
This will slow down checksum checking but does not thrash cache.
Compat with libuv 0.11 (Unstable)
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
Fix GnuTLS 2.x compatibility
AppleTLS: Use newer, non-deprecated API in 10.8+

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

New in aria2 1.17.1 Build 1 (May 28, 2013)

Changes:
Add code to detect rst2html.py or rst2html
AppleTLS: Properly support Snow Leopard (10.6)
Tested on 10.6.8 + XCode 4.2 (llvm-gcc-4.2, clang)
Enable multicast loopback in BitTorrent local peer discovery
Enable TLS1.1 with gnutls build
Support off64_t for Android build
Android NDK R8e does not provide ftruncate64, but bionic has the assembler code to access kernel function. We borrowed those ftruncate64.S files from android source code repository. It turns out that x86 asm.h in NDK R8e is also broken, so latest asm.h was also borrowed.
Check zlib availability usin AC_CHECK_LIB
This is workaround for zlib 1.2.3 which does not come with pkg-config file.
Treat response is completed if EOF is received before streamFilter completes
This fixes the error with web server which has buggy chunked encoding.
uitos: Fix off-by-one error bug
Add configure support for linking tcmalloc_minimal and/or jemalloc
Both tcmalloc_minimal and jemalloc outperform the native malloc implemention on Windows (MSVCRT) in terms of committed memory consumption (~-30%) and performance (e.g. far less page faults, ~-60%), depending, of course, on the actual workload. The longer the download queue, the bigger the impact ;)
On *nix the picture is a little different... tcmalloc usually still outperforms the native malloc implementation, but not that significantly than on Windows. jemalloc however is only marginally better than recent native Linux implementations, while it is already used by some BSD as the native allocator.
tcmalloc is part of gperftools and very mature and tested by now. It doesn't work on OSX in the default configuration, however. http://code.google.com/p/gperftools/
jemalloc is the default allocator at least on FreeBSD and NetBSD and used in Firefox. http://www.canonware.com/jemalloc/index.html
Close GZipFiles in the d'tor
Add libaria2, C++ library interface to aria2
The libaria2 is a C++ library and offers the core functionality of aria2. The library takes care of all networking and downloading stuff, so its usage is very straight forward right now. See libaria2ex.cc in examples directory to see how to use API. By default, libaria2 is not built. See libaria2 section in README to how to enable it.
The APIs in this release is considered experimental.
Add missing check for sigaction

New in aria2 1.17.0 Build 1 (Apr 22, 2013)

Updated Russian manual
Updated Portuguese manual
Append --static to pkg-config arguments when ARIA2_STATIC=yes
Save options directly specified for download in --save-session
This change makes --save-session save only options specified for download, more specifically, options in command-line, -i file and via RPC. The other options from conf file and default values are not saved. This will drastically decrease the size of session file.
Save URI returned only from FileEntry::getRemainingUris()
The currently used URIs are inserted back into remaining URI list in FileEntry::putBackRequest(), which overlaps to some of the URIs in spentUris_. If we save spent URIs, each time save is performed, the number of URIs are increased due to this overlap. This change fixes this bug.
Print linked 3rd party libraries with version in aria2c -v output
AppleTLS: Support credentials via KeyChain fingerprints
AppleTLS: Implement AppleTLS and Apple Message Digest
Use info level log for system trusted ca imports failure
This is because on some platforms (gnutls on cygwin for example), library always fails for this function and getting ERROR every time aria2c invoked is too hard.
Don't add Windows native DLLs for Cygwin build
Remove deprecated options: --enable-direct-io and --metalink-servers
Deprecate --enable-async-dns6
The IPv6 asynchronous name resolver is enabled if the host has at least one interface with IPv6 address configured (the loopback address will not be counted), which is roughly the same behaviour of the standard getaddrinfo(3). To disable IPv6 asynchronous name resolver, use --disable-ipv6.
Fix uninitialized UDPTrackerClient::numWatchers_
Implement simple Happy Eyeballs for HTTP/FTP downloads
Parallel A and AAAA record lookups with c-ares
But we don't wait for AAAA query response if A query response has been received. If we got IPv4 lookup response, we don't wait for IPv6 lookup response. This is because DNS server may drop AAAA query and we have t wait for the long time before timeout. We don't do the inverse, because, based on todays deployment of DNS server, almost all of them can respond A query just fine.

New in aria2 1.16.4 Build 1 (Mar 18, 2013)

Make configure argument meaning more consistent and obvious.
Most other software uses --disable/--without for features it does build or at least check by default.
Change aria2 configure options so that:
--enable-*: do not build by default, unless --enable specified
--disable-*: check and build by default, unless --disable specified
--with-*: do not use by default, unless --with specified
--without-*: check and use by default, unless without specified
Allow for out-of-tree Sphinx builds
Bring back datetime in console log
Run checksum check if -V and -c are used and file is completed
With -c option, aria2 can continue download after the existing file position. If it is not completed, then after completion aria2 runs checksum checking if available. But if existing file has already been completed, then CreateRequestCommand exits without issuing checksum checking. And aria2 treats it download error because it needs checksum verification but it has not been done. This change fixes this by properly checking download state and issue checksum checking before CreateRequestCommand.
Support for gzipped -i and --save-session
Saved sessions may very large, as in hundreds and even thousands of megabyte when dealing with large queues. Add support to save and reload sessions to gzipped files, when libz is available.
The session serializer will output gzipped contents when the file ends with .gz, while the input file reader (UriListParser) will accept whatever is thrown at it.
Document -i/--save-session gzip behaviour
Do not use a virtual varargs function
This stuff breaks in some compiler (configurations)
Check for sys/signal.h and/or signal.h
mingw-w64 does not actually have sys/signal.h, while OSX currently has a broken signal.h Better check the presence of both and use sys/signal.h if present, else signal.h
Hygiene: Fix some clang warnings, mostly unused private members.
Fix bustage on OSX with ./configure CC=cc CXX=c++ (clang)
Do not reference RequestGroups longer than necessary
There is an initial vector of SharedHandle to seed the DownloadEngine. This vector was however kept alive via main.cc -> MultiUrlRequestInfo up until the program exits, hence effetively leaking all initial RequestGroups and associated object instances.
Hence, as a matter of dirty-workaround, drop the contents of that initial vector as soon as it is not required any longer.
Detect console with on Windows
Fix infinite loop when size of downloadResults_ exceeds maxDownloadResult_
Support BitTorrent UDP tracker
It shares UDP listening port with IPv4 DHT. At the moment, in order to enable UDP tracker support, enable IPv4 DHT.
Show correct end byte in error message when HTTP response range is not ok
Previously, unless HTTP pipelining is enabled, end byte in that message is always 0. With this change, it shows correct end byte sent to the HTTP server.
Add Portuguese manual
This translation is based on aria2 version 1.15.2 manual.
Fix bug that active downloads are not saved with --save-session-interval

New in aria2 1.16.3 Build 1 (Feb 4, 2013)

New in aria2 1.16.2 Build 1 (Feb 4, 2013)

New in aria2 1.16.1 Build 1 (Dec 27, 2012)

mingw32: Re-open files with read-only mode enabled on seeding
On Mingw32 build, if aria2 opens file with GENERIC_WRITE access right, some programs cannot open the file aria2 is seeding. To avoid this situation, re-open files with read-only enabled when seeding is about to begin.
Save gid option with --save-session option
Added --gid option
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.
Use 64 bits random bytes as GID
This change replaces the current 64 bit sequential GID with 64 bits random bytes GID in an attempt to support persistent GID. Internally, the GID is stored as uint64_t. For human representation and RPC interface, GID is represented as 16 bytes hex string. For console readout, 16 bytes are too long, so it is abbreviated to first 6 bytes. When querying GID in RPC calls, user can speicfy the prefix of GID as long as the prefix is shared by more than 1 GID entries.
Fixed BitfieldMan::getOffsetCompletedLength overflow on 32-bit systems
mingw32: Use HANDLE only for MinGW32 build
Changed console readout, making it more compact
"SIZE:" is removed because it is obvious. SEEDING, SEED, SPD and UP are now replaced with SEED, SD, DL and UL respectively.
Compact readout when more than 1 simultaneous downloads are going on
If more than 1 simultaneous downloads are going on, use more compact format in readout. Currently, at most 5 download stats are displayed.
util::abbrevSize() is rewritten to support "Gi" unit and provides more compact abbreviation.
Console color output
Log level and download result string is now colored.
Logger: Simplified console output and change level format in log
The date and time are now removed from console output. The log level is now formatted as "[LEVEL]".
Start to find faster host before the number of missing segments becomes 1
The old implementation starts to find faster host when the number of missing segment becomes 1. Because of --min-split-size option, before the number of missing segment becomes 1, the number of connection becomes 1 and it can be slow. In this case, we have to wait until the last segment is reached. The new implementation starts to find faster host when the remaining length is less than --min-split-size * 2, to mitigate the problem stated above.
Removed warning when --file-allocation=falloc is used in MinGW32 build
The warning was just a mistake. SetFilePointerEx + SetEndOfFile actually allocate disk space.
Write data in 4K aligned offset in write with disk cache enabled
This greatly reduces disk activity especially on Win + NTFS.
mingw32: Removed FSCTL_SET_SPARSE set
Added --disk-cache option
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.

New in aria2 1.16.0 Build 1 (Dec 3, 2012)

mingw32: Open file using _wsopen and added --enable-mmap support
I tried CreateFile but the subsequent ReadFile fails with Access Denied if sparse file is read on NTFS. I mostly reverted previous changes and use _wsopen with read/write share enabled instead of CreateFile.
This change also includes --enable-mmap support for MinGW32 build. Memory mapped file may be useful for 64-bits OS and lots of RAM. Currently, FlushViewOfFile is not called during the download, so it is slightly vulnerable against sudden power loss. I found lots of read when resuming download due to page fault. So for now it is useful for the initial download. I recommend not to use --file-allocation=prealloc with --enable-mmap for MinGW32, because it triggers page faults even in the initial download. Anyway, the option is experimental.
Removed PO files and generated aria2.pot from repository
Currently, message translation is done at launchpad. All PO files can be exported from there. The merge process from launchpad is done when new release. First download export file from launchpad And use import-po script to import PO files into po directory.
Enabled TCP_NODELAY
Don't use AC_FUNC_MMAP
Don't use AC_FUNC_MMAP becaue it fails on some platforms (e.g., OpenWRT) which have mmap and it works in the way we use in aria2. Instead use mmap in AC_CHECK_FUNCS list.
Added --force-save option.
--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.
Get the correct uploaded data size
Subtract msgHdrLen_ from writtenLength to get the uploaded data size. Without this correction, the seeder assumes it has uploaded more data than it actually has.
Made --http-no-cache false by default
Fixed memory leak in AsyncNameResolver
Fixed resource leak in XmlParser and GenericParser
Reset iostream format state
gnutls: Added more status checking when verifying peer
Content-Disposition parser conforming to RFC 6266.
RFC 2231 Continuation is not supported.
Reworked download/upload statistics calculation
The old implementation calculates download/upload statistics for a RequestGroup by summing up all PeerStat objects. For global statistics, those are summed together. This clearly incurs runtime penalty and we introduced some kind of caching which updates statistics every 250ms but it did not work right.
This change removes all these aggregation code, and instead makes RequestGroup and RequestGroupMan objects hold NetStat object and download/upload bytes are directly calculated by thier own NetStat. This is far more simplar than the old way and less runtime penalty and brings more accuracy.
Added --rpc-save-upload-metadata option
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.
Perform SSL/TLS handshake after checking whether connection is established
Fixed bug that --enable-mmap won't work if MultiDiskAdaptor is used
RPC over SSL/TLS transport
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.
aria2rpc: Added appendUri command
This command calls aria2.changeUri(GID, fileIndex, [], [URI,...]) internally.
Don't send Proxy-Connection header field
Don't set SNI hostname if it does not include "." for GNUTLS
Disable SSL/TLS compression with OpenSSL
Pause download even if download is completed
This allows to pause and unpause BitTorrent seed.
Use execlp() instead of execl()

New in aria2 1.15.2 Build 1 (Sep 3, 2012)

Changes:
Catch exception from Socket::getPeerInfo() when pooling connection. Socket::getPeerInfo() may fail if its TCP connection has already disconnected. In this case, we log this error. The success or failure of pooling connection should not affect the later execution of the program. This bug may cause segmentation fault if Socket::getPeerInfo() throws exception during pooling connection after successful tracker request.
Fixed assertion error if --retry-wait is used. In CreateRequestCommand, if Request object returned from getRequest() is still sleeping, CreateRequestCommand pools it back but still holds its reference. This makes assertion error in UnknownLengthPieceStroage::hasMissingUnusedPiece() from AbstractCommand::execute().
Added new file allocation method called 'trunc'. --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.
Use int64_t instead of off_t. Using off_t, at least, in DiskAdaptor layer is problematic because torrent can contain under 2GiB files but total sum of those files may exceed 2GiB limit, which makes off_t overflow in 32 bit system without large file support. So we use int64_t in API. We'll check the file length before download so that it does not exceed max off_t.
Added TLS SNI support.
Rewritten timegm replacement function. The algorithm is based on Python 2.7 calendar.timegm.
Use system-wide certificates for SSL. Use system-wide certificates for SSL. For GnuTLS it requires the latest version, 3.0.20. OpenSSL had it for longer. This means that if SSL library is properly configured to locate system-wide certificates store, the user don't have to use --ca-certificate option. Also packagers don't have to use --with-ca-bundle configure option. Patch from Cristian Morales Vega
Fixed base64::decode() return "" if input ends with garbage and no padding.
Changed default Peer ID prefix. The new Peer ID prefix is "A2-$MAJOR-$MINOR-$MICRO-", where $MAJOR, $MINOR and $MICRO are the major version, the minor version and the micro version respectively. For instance, 1.15.2 release of aria2 will use "A2-1-15-2-".
Don't percent-decode filename value in Content-Disposition. We only percent-decode filename* value in Content-Disposition because the encoding is fully specified. But since filename value is not, so we just accept it as is.
Don't sum in-flight piece which does not intersect filtered ranges. When calculating completed length, don't sum the completed length of piece which does not intersect filtered ranges.
Fixed segmentation fault when logger failed to open log file.
Added ARIA2_STATIC precious variable to configure option. To build statically linked aria2 binary, give ARIA2_STATIC=yes to configure, like this: $ ./configure ARIA2_STATIC=yes
Use PRId64 for int64_t format specifier
Handle the case when MINGW32 vsnprintf returns -1. MINGW32 vsnprintf returns -1 if output is truncated. Increased buffer for vsnprintf in WinConsoleFile and fmt.
Added --enable-mmap option. If this option is used, map files into memory using mmap(2). This option is experimental.
Added CORS preflight request support in RPC interface. This change is based on the patch from binux.

New in aria2 1.14.0 Build 1 (Dec 27, 2011)

Updated Chinese (Simplified), Spanish, French and Russian translations.
Updated Russian man page.
Ignore peer which possibly sent bad data in next few minutes. In aria2, one piece is downloaded from several peers, so when hash check failed for that piece, it cannot determine which peer(s) sent bad data. So, we ignore peer who sent last block of data in random minutes. We use randomized timeout because all peers get waken up at the almost same time.
Added suggestion for unknown/ambiguous options. The help messages shown when argument error were redesigned and less verbose now. When unknown or ambiguous option is given, show suggestions like "Did you mean...". Some constant values related to levenstein distance are borrowed from git help.c.
Added --stop-with-process=PID option. 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 Support IPv6 address for FTP via HTTP tunneling.
The previous implementation could not handle the situation when user, password and proxy URI is given various order. Now we just set rules: username set in --
-proxy-user overrides username in --
-proxy option, no matter in any order username, password and proxy URI are parsed. Likewise, password set in --
--proxy-passwd overrides password in --
-proxy option.
Changed format of ETA. Now no leading 0 is used. If hour part and/or min part is non-zero, and sec part is 0, sec part is omitted, like this "1h3m". Rewritten Metalink XML parser. Now we don't strip white spaces while parsing Metalink V3 document.
Now xml attribute and characters in RPC request is not stripped at all.
Fixed bug that some information such as port number is lost if redirect URI contains only path component.
Apply PREF_MAX_CONNECTION_PER_SERVER to BitTorrent WEB Seeding hosts.
Reuse in-flight and pooled URIs when a download is paused.
Deprecated --metalink-server option. Use --split option instead.
Made max value of --select-file to 65535
Use same domain-match algorithm for no-proxy and netrc. Now "example.org" does not domain-match ".example.org" in both functions.
For waiting or paused downloads, the options listed in Input File subsection in man page are available in aria2.changeOption RPC method, except for following options: dry-run, metalink-base-uri, parameterized-uri, pause and piece_length.
Made --download-result, --save-session, --server-stat-of and --save-cookies option available in aria2.changeGlobalOption. In addition to them, the options listed in Input File subsection in man page are also available, except for following options: checksum, index-out, out, pause and select-file.
Made --uri-selector option available in -i list.
Support IPv6 literal address in proxy option.
Support IPv6 CIDR block in --http-no-proxy option.
HttpProxyOptionHandler: Enclose hostname with square brackets if hostname is IPv6 numeric address.
