Release Note

This release fixes lots of bugs. See the Changes section below.

Changes

• Fix bug that pause/unpause seeding torrent prevents new downloads
  from starting

  Previously, with --bt-detach-seed-only, when user issued pause and
  unpause command to seeding torrent, and it was started again, and it
  immediately got seeding status, but aria2 did not start new download
  waiting in the queue. This commit fixes this bug.

  See GH-490

• Add --bt-enable-hook-after-hash-check option

  This option sets flag which allows hook command invocation after
  hash check (see -V option) in BitTorrent download. By default, when
  hash check succeeds, the command given by --on-bt-download-complete
  is executed. To disable this action, give false to this option.

• Add --socket-recv-buffer-size option

  Set the maximum socket receive buffer in bytes. Specifing 0 will
  disable this option. This value will be set to socket file
  descriptor using SO_RCVBUF socket option with setsockopt() call.

  See GH-487 about the usecase of this option

• Disable --deferred-input when --save-session is used together

  With --deferred-input=true, aria2 only reads input file to fill
  active download slots, while keeping input file open. Meanwhile,
  --save-session saves all download info inside memory, but this does
  not take into account of unread item in input file. This will lead
  to lose input data in saved session file. Also current BufferedFile
  implementation used to read/write input/output file take a lock on
  Windows. This effectively prevents session serializer from writing
  session data to the same file which is still kept open because of
  --deferred-input. See GH-493

• base32: decode lowercased characters as well

  This fixes the bug that magnet URI with lowercased btih is treated
  as malformed.

• mingw: Use GetFileSize to get file size

  _wstat family does not work with symbolic links. They always
  returns size 0. To workaround this, we now use GetFileSize to get
  file size. To do that, we need to first obtain file HANDLE, which
  is a bit tedious because of the messy interface of CreateFileW, but
  we have no way to get around it.

• Fix bug that file allocation=trunc does not work with Windows
  symlink

• Send the last error message as part of tellStatus RPC response

  Patch from Jarda Snajdr

• Don't enable mmap if file allocation is disabled

  Without file allocation, we cannot map file because file length
  could be zero.

  This could fix bug reported at GH-478

• Evict timed out pooled socket periodically

  Previously we only scanned pool socket to check they are timed out
  when we pooled another socket. This means that pooled socket is not
  closed long time (stays in CLOSE-WAIT state) if we don't pool any
  more socket. In this commit, we now check pooled socket
  periodically (30 seconds) to avoid the sockets hanging in CLOSE-WAIT
  state long time.

  See GH-477

• Don't write control file if content is not changed from previous one

  This is desirable so that we don't have to wake up disk if control
  file is not changed, and it is not have to be written again. We use
  the same method (SHA1 hash) to check the content is the same. The
  limitation is the hash is stored in memory, so we have to write the
  first time in each session.

  See GH-382

• Remove content-length and content-range if transfer-encoding is
  given

  See GH-473

• Retry after 404 status if --max-file-not-found > 0
