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.

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
