Changes

4.5.0 (2025-01-08)

• Make the modules in nti.zodb.btrees.family64LargeBuckets properly provide the set operations like multiunion. Previously, due to an error in BTrees, these were not available.

4.4.1 (2024-12-24)

• Make IZODBZConfigProvider correctly extend IZODBConfigProvider.

4.4.0 (2024-12-24)

• Make provideDatabases properly return the mapping of all installed databases.

• Make provideDatabases and related APIs detect and collapse equal databases into a single component. This is handy for aliases, for example while evolving a code base.

4.3.0 (2024-12-23)

• Add a series of interfaces and APIs supporting database configuration and registration for use during process startup. See nti.zodb.config_providers.provideDatabases.

4.2.0 (2024-12-02)

• Add a case-insensitive but case-preserving BTreeContainer and BTreeFolder.

1.4.0 (2024-11-08)

• Drop support for Python < 3.10.

• Use native namespace packages.

1.3.0 (2021-04-01)

• Add support for Python 3.9.

• The ZODB activity log monitor now has separate thresholds for loads and stores, in addition to the total combined threshold; exceeding any threshold will trigger logging.

  The thresholds have all been set to 10, but can be configured with environment variables.

  See issue 11.

1.2.0 (2020-08-06)

• Add a BTree “family” object to nti.zodb.btrees that uses larger bucket sizes. See issue 8.

• All numeric minmax objects implement the same interface, providing the increment method. See issue 7.

• The merging counter does the right thing when reset to zero by two conflicting transactions. See issue 6.

1.1.0 (2020-07-15)

• Add support for Python 3.7 and 3.8.

• Loading this package’s configuration no longer marks persistent.list.PersistentList as implementing the deprecated interface zope.interface.common.sequence.ISequence. This conflicts with a strict resolution order. Prefer zope.interface.common.collections.ISequence or its mutable descendent, which PersistentList already implements.

• Rework nti.zodb.activitylog to be faster. Client code may need to adapt for best efficiency.

• The monitors in nti.zodb.activitylog now include information about the ZODB connection pool. See issue 4.

• The log monitor now has a configurable threshold, defaulting to at least one load or store. See issue 3.

1.0.0 (2017-06-08)

• First PyPI release.

• Add support for Python 3.

• Remove nti.zodb.common. See https://github.com/NextThought/nti.zodb/issues/1. ZlibClientStorageURIResolver will no longer try to set a var directory to store persistent cache files automatically.

• CopyingWeakRef now implements ICachingWeakRef.
