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
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).
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.
Now you can build bittorrent support without without external
libraries, meaning you can skip libnettle, libgmp, libgcrypt, GnuTLS and
OpenSSL on OSX (for now).
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).
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.
IOFile provides the same interface of old BufferedFile. It provides
extension points as pure virtual functions. Those functions are
implemented by 2 concrete subclasses: BufferedFile and GZipFile.
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.
By default, libaria2 feature is disabled. Use --enable-libaria2
to enable it. libaria2 static build is also disabled by default.
Use --enable-static to enable it.
LibUV event will use the best available polling method on a system, kind
of like aria2 does already with the different *EventPoll
implementations.
However, libuv may support different/newer polling mechanisms; for
example on Windows it will use IO Completion Ports which are superior to
select() ;)
Now dedicated ConnectCommand handles connection establishment. It
checks whether connection is established or not. It also handles
backup connection. The next Command creation is abstracted using
ControlChain struct template.
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.
--save-session-interval option saves error/unfinished downloads to a
file specified by --save-session option every SEC seconds. If 0 is
given, file will be saved only when aria2 exits.
