Version history

Plyvel 0.9

Release date: 2014-08-27

• Ensure that the Python GIL is initialized when a custom comparator is used, since the background thread LevelDB uses for compaction calls back into Python code in that case. This makes single-threaded programs using a custom comparator work as intended. (issue #35)

Plyvel 0.8

Release date: 2013-11-29

• Allow snapshots to be closed explicitly using either :py:meth:`Snapshot.close()` or a with block (issue #21)

Plyvel 0.7

Release date: 2013-11-15

• New raw iterator API that mimics the LevelDB C++ interface. See :py:meth:`DB.raw_iterator()` and :py:class:`RawIterator`. (issue #17)
• Migrate to pytest and tox for testing (issue #24)
• Performance improvements in iterator and write batch construction. The internal calls within Plyvel are now a bit faster, and the weakref handling required for iterators is now a lot faster due to replacing :py:class:`weakref.WeakValueDictionary` with manual weakref handling.
• The fill_cache, verify_checksums, and sync arguments to various methods are now correctly taken into account everywhere, and their default values are now booleans reflecting the the LevelDB defaults.

Plyvel 0.6

Release date: 2013-10-18

• Allow iterators to be closed explicitly using either :py:meth:`Iterator.close()` or a with block (issue #19)
• Add useful __repr__() for :py:class:`DB` and :py:class:`PrefixedDB` instances (issue #16)

Plyvel 0.5

Release date: 2013-09-17

• Fix :py:meth:`Iterator.seek()` for :py:class:`PrefixedDB` iterators (issue #15)
• Make some argument type checking a bit stricter (mostly None checks)
• Support LRU caches larger than 2GB by using the right integer type for the lru_cache_size :py:class:`DB` constructor argument.
• Documentation improvements

Plyvel 0.4

Release date: 2013-06-17

• Add optional 'default' argument for all .get() methods (issue #11)

Plyvel 0.3

Release date: 2013-06-03

• Fix iterator behaviour for reverse iterators using a prefix (issue #9)
• Documentation improvements

Plyvel 0.2

Release date: 2013-03-15

• Fix iterator behaviour for iterators using non-existing start or stop keys (issue #4)

Plyvel 0.1

Release date: 2012-11-26

• Initial release
