aria2 1.20.0
============

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

This release fixes lots of bugs.  See the Changes section below.
There are new features in this release.  We added "seeder" key in
aria2.tellStatus RPC response.  We added system.listMethods RPC method
to return all RPC method supported.  We added --max-mmap-limit option
to avoid mmap if total file size is greater than given size.

Changes
-------

* src/WinConsoleFile.cc: fix colour

  Set default foreground/background colour correctly

  Patch from kwkam

* configure.ac: fix autoreconf error

  Use m4_ifdef so we do not have to install optional libraries

  Patch from kwkam

* Don't inherit file descriptor to child process

  For non-Mingw32 build, set FD_CLOEXEC to file descriptors which live
  beyond function scope.  For Mingw32 build, just pass false to
  bInheritHandles parameter of CreateProcessW.

* Update Russian version documentation

  Patch from ITriskTI

* Add "seeder" key to tellStatus RPC response

* WinTLS: Fix hang because of buffered received data

  WinTLSSession buffers received decrypted data into its own buffer.
  If read is requested, it copies the data from its buffer.  But if
  requested buffer size is less than decrypted buffer, some of the
  data is left in the buffer.  Previously, we had no facility to check
  the existence of this pending data.  If this data is the last
  requested data from remote server, we may end up waiting for read
  event even if we have already data in our buffer, which may cause
  hang.  This commit fixes this issue by introducing function to
  return the buffered length in TLSSession.  SocketCore also provides
  the same function, which delegates to TLSSession object.

* Add --max-mmap-limit option

  Set the maximum file size to enable mmap (see --enable-mmap
  option). The file size is determined by the sum of all files
  contained in one download. For example, if a download contains 5
  files, then file size is the total size of those files. If file size
  is strictly greater than the size specified in this option, mmap
  will be disabled.

* mingw: Use SetFileValidData to make --file-allocation=falloc work

* Retry with 504 status code

* Increase DHT transaction ID from 2 to 4 bytes to avoid conflict

* Update wslay

* Add --enable-werror option to configure to enable warning flags

* Don't modify user variables (e.g., CFLAGS, LIBS, etc)

* Improve error message when loading pkcs12 file failed

* Updated dependency and source url's

  The RaspberryPi Dockerfile had some out-of-date dependency packages
  and was downloading an outdated aria2 source from Sourceforge, which
  resulted in a build for version 1.19.0.  The new
  fetch-latest-release-from-GitHub script I've cooked up should always
  work as long as GitHub doesn't change their API and aria2's platform
  agnostic releases follow the "{version number}.tar.bz2" naming
  format.

  Patch from c3mb0

* Reduce delay in tracker request

  We eliminated 1 second delay between completion of name resolution
  for tracker request and time when it is actually issued.  We also
  elimited 1 second delay after last torrent download exists and it is
  told to DHTInteractionCommand.

* Disable IPv6 on non-async NameResolver if configuration wants

* Fix mysterious 1 second delay with async DNS

* Fix bug that UDP port was incorrectly used in UDP tracker announce request

* Refactor HttpRequest

  This also makes comparison performed when replacing builtin header
  field with user-defined one case-insensitive.

* Send Want-Digest as per RFC 3230

* Try all found address set to bind sockets with --multiple-interface

  Fixes GH-523

* Replace sourceforge references with aria2.github.io

* Add system.listMethods RPC method

  system.listMethods just returns the available RPC method names.  It
  can be executed without secret token, because it just returns the
  method names, and does not alter anything.

  See GH-437

* Support content-range from non-compliant server

  See GH-509

* Reduce UDP tracker request timeout

  See GH-507

* Apply --retry-wait when retrying after 404

  Previously, --retry-wait was not used when retrying after 404
  (--max-file-not-found).  The retry was done without delay.  Also the
  maximum retry count (--max-retries) was ignored when retrying with
  404.

  This commit makes --retry-wait apply for retrying with 404 as well.
  It also combines --max-retries and --max-file-not-found.  When
  retrying with 404, it is counted toward retry count.
