aria2 1.19.1

Release Note

This release fixes TLS handshake error with servers which only support
RSA-SHA1 signature algorithm. We removed RSA-SHA1 for enchanced
security, but many users reported there were servers which could not
talk aria2 1.19.0, so added it again for compatibility reasons. For
Windows build, we fixed potential infinite loop bug when TLS is used.

We changed the location where dht.dat and aria2.conf are looked up.
The aria2 manual page described details. Basically we now follow XDG
specification (http://standards.freedesktop.org/basedir-spec/latest/).
For dht.dat, the default location is $XDG_CACHE_HOME/aria2/ directory.
For aria2.conf, the default location is $XDG_CONFIG_HOME/aria2/
directory. To keep the current user configuration working, if aria2
detects dht.dat under $HOME/.aria2/ directory, it is used instead.
Similarly, if aria2.conf exists under $HOME/.aria2/ directory, it is
used instead.

Previously, we return 500 HTTP status if RPC method execution
encountered error. Now it returns with 400 HTTP status with error
code. This is more natural because server processed request and found
an error, and returned error reply correctly. This is not something
server crashed or something. Also, there is RPC libraries which
throws exception if it sees 5XX status code, where 400 is better
because we can examine the error.

Changes

• Update README.android

  Providing some workarounds about CA certificates and standard output

  Patch from amtlib-dot-dll

• Return 400 HTTP status code if exception was caught while executing
  RPC method

  Previously, we returned 500 HTTP status code. I think the found in
  RPC level, not in HTTP protocol, so 500 is not appropriate.

• WinTLS: Fix potential infinite loop

• Fix on-download-error is executed even if download succeeded

• Update Dockerfile.mingw

  Patch from Adam Baxter

• Increase --select-file upper bound to 1m for torrent containing lots
  of files

• Fix busy loop with --dry-run and 4xx response for URI listed in
  metalink

  See GH-430

• Update sqlite in OSX build to 3.8.10.2

• Make LibuvEventPoll compatible with the latest libuv again

• gnutls: Allow SIGN-RSA-SHA1 for compatibility reason

• Make script compatible with both Python 2 and 3

  Patch from Vasilij Schneidermann

• Make config and cache files conform to XDG

  See http://standards.freedesktop.org/basedir-spec/latest/ for
  further details. This implementation decides the default based on
  whether a file exists at the legacy location, if it doesn't, it
  picks the XDG-conforming location instead.
