Notable Changes

v4.0.1

Security fix:

  • getSub() now returns null when it encounters a non-"own" property (including __proto__) or any non-object while walking the given property path. This should make it easier to avoid accidental prototype pollution vulnerabilities.

v4.0.0

Compatibility changes:

  • redis: The socket and client_options settings, deprecated since v1.3.1, have been removed.
  • redis: The client configuration object has changed with the new version of the redis client library. See the redis client library documentation for details.

Bug fixes:

  • redis: Several findKeys() fixes.

Updated database dependencies:

  • redis: Updated redis from 3.1.2 to 4.1.0.

v3.0.2

Security fix:

  • getSub() now returns null when it encounters a non-"own" property (including __proto__) or any non-object while walking the given property path. This should make it easier to avoid accidental prototype pollution vulnerabilities.

v3.0.1

Bug fixes:

  • Fixed findKeys() calls containing special regular expression characters (applicable to the database drivers that use the glob-to-regex helper function).

v3.0.0

Compatibility changes:

  • Minimum supported Node.js version is now 14.15.0.
  • elasticsearch: New index name and mapping (schema). To automatically copy existing data to the new index when the ueberdb client is initialized, set the migrate_to_newer_schema option to true.
  • As mentioned in the v2.2.0 changes, passing callbacks to the database methods is deprecated. Use the returned Promises instead.
  • postgrespool: As mentioned in the v1.4.15 changes, postgrespool is deprecated. Use postgres instead.
  • redis: As mentioned in the v1.3.1 changes, the socket and client_options settings are deprecated. Pass the client options object directly.

Bug fixes:

  • elasticsearch: Rewrote driver to fix numerous bugs and modernize the code.

Updated database dependencies:

  • couch: Updated nano to 10.0.0.
  • dirty_git: Updated simple-git to 3.7.1.
  • elasticsearch: Switched the client library from the deprecated elasticsearch to @elastic/elasticsearch version 7.17.0.
  • postgres: Updated pg to 8.7.3.
  • sqlite: Updated sqlite3 to 5.0.6.

v2.2.4

Security fix:

  • getSub() now returns null when it encounters a non-"own" property (including __proto__) or any non-object while walking the given property path. This should make it easier to avoid accidental prototype pollution vulnerabilities.

v2.2.0

Compatibility changes:

  • Passing callbacks to the database methods is deprecated; use the returned Promises instead.

New features:

  • Database methods now return a Promise if a callback is not provided.

Bug fixes:

  • A call to flush() immediately after a call to set(), setSub(), or remove() (within the same ECMAScript macro- or microtask) now flushes the new write operation.
  • Fixed a bug where findKeys() would return stale results when write buffering is enabled and writes are pending.
  • couch: Rewrote driver to fix numerous bugs.

v2.1.1

Security fix:

  • Fix setSub() prototype pollution vulnerability.

v2.1.0

  • memory: New data setting that allows users to supply the backing Map object (rather than create a new Map).

Updated database dependencies:

  • dirty_git: Updated simple-git to 3.6.0.
  • mssql: Updated mssql to 8.1.0.

v2.0.0

  • When saving an object that has a .toJSON() method, the value returned from that method is saved to the database instead of the object itself. This matches the behavior of JSON.stringify(). The .toJSON() method is used even if the chosen database driver never actually converts anything to JSON.
  • New memory database driver that stores values in memory only.

v1.4.19

Updated database (and other) dependencies:

  • mongodb: Updated mongodb to 3.7.3.
  • mssql: Updated mssql to 7.3.0.
  • dirty_git: Updated simple-git to 2.47.0.

v1.4.16

  • postgres: You can now provide a connection string instead of a settings object. For example: 
    const db = new ueberdb.Database('postgres', 'postgres://user:password@host/dbname');

v1.4.15

  • postgres, postgrespool: The postgrespool database driver was renamed to postgres, replacing the old postgres driver. The old postgrespool name is still usable, but is deprecated. For users of the old postgres driver, this change increases the number of concurrent database connections. You may need to increase your configured connection limit.
  • sqlite: Updated sqlite3 to 5.0.2.

v1.4.14

Updated dependencies:

  • cassandra: Updated cassandra-driver to 4.6.3.
  • couch: Updated nano to 9.0.3.
  • dirty: Updated dirty to 1.1.3.
  • dirty_git: Updated simple-git to 2.45.0.
  • mongodb: Updated mongodb to 3.6.11.
  • mssql: Updated mssql to 7.2.1.
  • postgres, postgrespool: Updated pg to 8.7.1.

v1.4.13

  • mongodb: The dbName setting has been renamed to database for consistency with other database drivers. The dbName setting will continue to work (for backwards compatibility), but it is deprecated and is ignored if database is set.
  • mongodb: The database (formerly dbName) setting is now optional. If it is not specified, the database name embedded in the url setting is used.

v1.4.8

  • redis: Updated redis dependency to 3.1.2.

v1.4.7

  • Each write operation in a bulk write batch is now retried if the bulk write fails.
  • Fixed write metrics for setSub() read failures.

v1.4.6

  • mysql: Use a connection pool to improve performance and simplify the code.

v1.4.5

  • mysql: Reconnect on fatal error.
  • mysql: Log MySQL errors.

v1.4.4

  • New experimental setting to limit the number of operations written at a time when flushing outstanding writes.
  • mysql: Bulk writes are limited to 100 changes at a time to avoid query timeouts.
  • mysql: Raised default cache size from 500 entries to 10000.

v1.4.2

  • Refined the experimental read and write metrics.

v1.4.1

  • The two callback arguments in remove(), set(), and setSub() have changed: Instead of a callback that is called after the write is buffered and another callback that is called after the write is committed, both callbacks are now called after the write is committed. Futhermore, the second callback argument is now deprecated.
  • Modernized record locking.
  • Experimental metrics for reads, writes, and locking.

v1.3.2

  • dirty: Updated dirty dependency.

v1.3.1

v1.2.9

  • dirty: Workaround for a bug in the upstream dirty driver.

v1.2.7

  • redis: Experimental support for passing the settings object directly to the redis package.

v1.2.6

  • redis: Fixed "Callback was already called" exception during init.

v1.2.5

  • All: Fixed a major bug introduced in v1.1.10 that caused setSub() to silently discard changes.
  • All: Fixed a bug that prevented cache entries from being marked as most recently used.

v1.2.4

  • mssql: Updated mssql dependency.
  • dirty_git: Updated simple-git dependency.
  • sqlite: Updated sqlite3 dependency.

v1.2.3

  • mssql: Updated mssql dependency.

v1.2.2

  • All: Fixed minor setSub() corner cases.

v1.2.1

  • New flush() method.
  • The doShutdown() method is deprecated. Use flush() instead.
  • The close() method now flushes unwritten entries before closing the database connection.
  • Bug fix: null/undefined is no longer cached if there is an error reading from the database.

v1.1.10

  • Major performance improvement: The caching logic was rewritten with much more efficient algorithms. Also: Scans for entries to evict is performed less often. Depending on your workload you might observe a slight memory usage increase.

v1.1.7

  • mysql dependency bumped to 7.0.0-alpha4 to avoid a security vulnerability in one of its indirect dependencies.

v1.1.6

  • Bug fix: When write buffering is disabled, reads of keys with values that were changed but not yet written to the underlying database used to return the previous value. Now the updated value is returned.
  • Minor performance improvement: Setting a key to the same value no longer triggers a database write.

v1.1.5

  • Minor performance improvement: Debug log message strings are no longer generated if debug logging is not enabled.

v1.1.1

  • The database() constructor is deprecated; use Database() instead.
