Changelog:

aria2 1.15.2
============

Release Note
------------

This release fixes several critical bugs. It also adds new features
such as TLS SNI and CORS support. The --file--allocation option now
take another value trunc. The new option --enalbe-mmap was added.
aria2 now uses system-wide SSL/TLS certificates by default, which
eliminates the requirement to specify --ca-certificate option.

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.
