2024-06-13 4.2.7
- Exclude tests from the package.
2024-03-25 4.2.6
- Validate creation date if it exists.
2024-03-09 4.2.5
- Bugfix: Include symbolic links in the torrent's files.
2023-12-04 4.2.4
- Bugfix: Remove hardcoded minimum and maximum piece sizes from
Torrent.calculate_piece_size().
2023-12-01 4.2.3
- Torrent.calculate_piece_size() now returns 16 MiB for content sizes bigger
than 16 GiB. (Thanks @cannibalChipper)
2023-09-11 4.2.2
- Fix a bug that was introduced in 4.2.0. Instead of forcibly decoding all
encodings as UTF-8, go back to defaulting to undecoded bytes (like before)
and only perform a decode-and-replace-invalid-characters routine on known
strings like ["info"]["name"].
2023-07-02 4.2.1
- Setting Torrent.piece_size_min/max now also sets Torrent.piece_size if it is
too small/big.
2023-04-16 4.2.0
- When reading torrent files, strings are now always decoded as UTF-8 (except
for ["info"]["pieces"]). This makes it harder to store binary data in
non-standard fields, but it also means ["info"]["name"] is always a unicode
string.
- Allow any "piece length" that is divisible by 16 KiB.
Previously, power of 2 was required.
2023-01-26 4.1.4
- Fix "Too many open files" error when creating a torrent with loads of small
files.
2023-01-09 4.1.3
- Try to reduce memory usage before being out of memory.
- Terminate piece hashing threads if they are idle for more than
500 milliseconds.
2022-11-24 4.1.2
- Bugfix: Torrent's piece_size_min and piece_size_max arguments are no longer
ignored.
- Torrent.piece_size_min and Torrent.piece_size_max are now properties. They
default to the new class attributes piece_size_min_default and
piece_size_max_default.
- Torrent.calculate_piece_size(): New arguments: min_size, max_size specify
the minimum and maximum piece size.
2022-11-15 4.1.1
- Bugfix: Don't crash if "creation date" is something weird like an empty
string.
2022-11-09 4.1.0
- Torrent now accepts piece_size_min and piece_size_max arguments.
- Bugfix: Don't reuse a torrent that has a smaller piece_size than
piece_size_min.
2022-09-22 4.0.4
- Bugfix: Expect non-standard fields (e.g. "md5sum") in file list when reusing
torrent.
2022-07-02 4.0.3
- Bugfix: Copy file order from reused torrent.
2022-06-19 4.0.2
- Bugfix: Don't reuse a torrent that has a bigger piece_size than
piece_size_max.
2022-05-17 4.0.1
- Bugfix: RecursionError when pickling File objects
2022-05-05 4.0.0
- Torrent.verify(): The "skip_on_error" argument was removed.
- The new TorrentFileStream class lets you operate on a torrent's stream of
concatenated files.
- The new attribute Torrent.location provides the file system path without the
torrent's name.
- The new Torrent.reuse() method copies piece hashes from an existing torrent
file with the same name and file tree. It can also find a matching torrent
in a bunch of directories.
2020-10-29 3.1.3
- Bugfix: Exclude tests from package.
2020-10-25 3.1.2
- Bugfix: Preserve binary values of fields that aren't part of the BitTorrent
specification.
(Thanks, @ayasechan)
2020-09-26 3.1.1
- Bugfix: Fix poor performance when torrent contains huge number of files
(Thanks, @mon)
2020-08-11 3.1.0
- Bugfix: Gracefully handle empty string for "url-list" and other URL lists in
metainfo
- The new properties Torrent.include_globs and Torrent.include_regexs can be
used to keep files even if they match an exclude pattern.
2020-06-20 3.0.2
- Bugfix: Torrent.validate() and Torrent.read_stream() now raise MetainfoError
if the "info" field is not a dictionary.
- Bugfix: Magnet.from_string() raised ValueError instead of MagnetError if the
"xl" parameter wasn't a number.
- Bugfix: Magnet.from_string() strips whitespace from the beginning and end
before parsing the URI.
- Bugfix: Magnet.kt used commas to separate keywords. (I don't know why.)
- Bugfix: Gracefully handle empty path components in torrent file
(e.g. "foo//bar")
- Torrent.private is now None instead of False if there is no "private" field
in the "info" section of the metainfo.
2020-04-07 3.0.1
- Make things work with Python 3.6.
- Magnet.as_torrent is now a method called Magnet.torrent().
2020-04-02 3.0.0
- Depend on flatbencode instead of bencoder.pyx
- Bug fixed: Setting the "private" property to False removed the flag from the
metainfo which could potentially change the info hash if a torrent file had
the flag explicitly disabled.
- Bug fixed: Torrent.read() validated if the "validate" argument was False
- Hashing pieces uses multiple threads for better performance.
- Support for the "md5sum" field was dropped. Calculating MD5 hashes besides
the SHA1 hashes is no longer easily possible due to multithreading and it's
unclear to me if/how this field is even useful.
- The new methods Torrent.verify_content() and Torrent.verify_filesize() check
if on-disk data matches a given torrent file.
- The property Torrent.exclude was replaced by Torrent.exclude_globs and
Torrent.exclude_regexs. These return special lists that filter files when
changed.
- Torrent.path is a path-like object.
- Torrent.files, Torrent.filepaths, Torrent.trackers, Torrent.webseeds and
Torrent.httpseeds are mutable lists of path-like objects or URLs that
automatically synchronize with Torrent.metainfo when changed.
- Torrent.filetree uses File objects as leaf nodes. File is a path-like
object that also stores the file size.
- The new class attributes Torrent.piece_size_min and Torrent.piece_size_max
can be used to quickly specify piece size limits. Setting the piece_size
property to an out-of-bounds piece size or returning one with
Torrent.calculate_piece_size() raises PieceSizeError.
- Torrent.validate() is better at finding invalid stuff in the metainfo.
- Exceptions were added and removed. If you don't catch TorfError, make sure
you're expecting the correct exceptions.
- Except for ReadError and WriteError, exceptions no longer have an "errno"
property.
- When setting the Torrent.path property to None, only "pieces" is removed
from the metainfo. "piece length", "pieces", "length" and "files" are kept.
"name" is only changed when a new path is set.
- The license was changed to GPLv3.
2019-07-01 2.1.0
- Keep piece size smaller for large torrents and use more pieces to
compensate.
- Implement your own piece size calculation of arbitrary complexity by simply
overloading Torrent.calculate_piece_size().
2019-04-04 2.0.0
- Use proper version number scheme
- Raise PieceSizeError if 'piece_size' is set to a number that isn't a power
of two
2018-06-25 1.5
- New methods read_stream() and write_stream() to import/export a torrent from
any file-like object
2018-06-15 1.4
- New method: calculate_piece_size()
- Piece size is now automatically calculated when path is set instead of
calculating it on demand when requested
- Setting piece size to a non-number now raises ValueError instead of
RuntimeError
- Exclude patterns are now matched against every part of a file's path, not
just the last part (i.e. the file name)
- Setting torrent.path to '.' or '..' now sets the correct name
- Torrent instances are equal (==) if their metainfo is equal
- Torrent instances are hashable
- Torrent instances can be copied with the copy() method or the copy module
from the standard library
2018-04-07 1.3
- Fix 'filepaths' attribute when setting a custom name
2018-02-19 1.2
- Don't leave an empty file when calling write() on an invalid torrent
2018-02-18 1.1
- 'announce' in metainfo is now a single URL instead of the first tier (Marcin
Kurczewski)
2018-02-01 1.0
- Nothing changed except that this is now the final 1.0 version
2018-01-13 1.0rc5
- Fixed a bug where overwriting a torrent file resulted in corrupt torrent
- Added property 'pieces' that returns the number of pieces
- Added property 'filetree' that can be used to create a beautiful tree of a
torrent's content
- Added property 'is_ready' that is True when torrent can be exported
- When reading torrent files, don't read large files all the way to EOF before
failing
- All exceptions now have an 'errno' attribute (see 'errno' module)
2018-01-03 1.0rc4
- Torrent.write() and Torrent.read() take a file path instead of an opened
file object
- Some exception names have changed
- Allow reading arbitrary bencoded data with validation turned off
- Default 'created_by' value is now 'torf/<version>'
2017-12-27 1.0rc3
- Reduce entropy with 'randomize_infohash' enabled (some parsers seem to have
issues with large integers)
2017-12-25 1.0rc2
- Add 'randomize_infohash' as a Torrent argument
- Add 'name' as a Torrent argument
- Call generate() callback again when all pieces are hashed
- Validate 'metainfo' when accessing 'infohash' property
2017-12-21 1.0rc1
Initial release
