aria2 1.18.10
=============
Release Note
------------
This releases fixes several bugs reported since the last release.
Changes
-------
* Add encoding specifier to Russian man page
Fixes GH-341
* Mingw: Use _wgetenv to get user's home directory
Fixes GH-342
* Handle linux getrandom returning EINTR on interrupts/signals
Also handle ENOTSUP failures where aria2 was build with linux
headers newer than the actual running kernel.
Fixes GH-336
aria2 1.18.9
============
Release Note
------------
This releases fixes memory leak with OpenSSL and crash on OSX when
proxy is used. We added several new features. Adler32 checksum is
now available in --checksum option and hash element in Metalink files.
We added --bt-detach-seed-only option, which excludes seed-only
downloads when counting concurrent active downloads (-j option). We
disabled SSLv3 by default. If you ever want to enable it or further
tune the TLS protocols to enable, use new --min-tls-version option.
--bt-force-encryption option was added to make requiring BitTorrent
full encryption easier. From this release, we build Android binary
using API level 16.
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
Patch from Dan Fandrich
* 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
Patch from David Macek
* Fix crash on OSX when proxy is used
See GH-275
* Support Adler32 checksum
Adler32 checksum is available for --checksum option and hash element
in Metalink files. Currently, we use Adler32 implementation in
Zlib.
aria2 1.18.8
============
Release Note
------------
This releases fixes the bug that aria2 cannot read piped stdin on
mingw32. It also fixes busy loop on mingw32 when SSL/TLS is used. We
also fixed 2 crashes which can occur on all platforms.
Changes
-------
* WinTLS: Fix abrupt connection closing and closing in general.
Fixes GH-277
* LibsslTLSSession: Treat 0 from readData as EOF
* Enable dynamicbase and nxcompat in Windows binaries
* Fix crash in OpenedFileCounter::ensureMaxOpenFileLimit()
The crash happens if PieceStorage and/or DiskAdaptor are not
initialized in one of active RequestGroups.
* mingw32: Fix bug that aria2 does not read piped stdin
* Fix std::length_error when no_proxy is used
This is regression introduced in 8cada497.
* Try to set sane limits for RLIMIT_NO_FILE
E.g. on OSX the default is 256, which isn't exactly compatible with
torrent downloads.
Closes GH-257
* Delay auth failures instead of PBKDF2
Closes GH-256
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
