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.
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.

jemalloc is the default allocator at least on FreeBSD and NetBSD and
used in Firefox.

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() ;)
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
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.
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
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.
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.
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.

Check sockaddr_in.sin_len and sockaddr_in6.sin6_len are available and
assign values to them properly. This change fixes unit test error and
most error related to getnameinfo() on netbsd.
