This adds support for serializing/deserializing objects which implement the JsonCodecable interface from the wikimedia/json-codec library used by Parsoid. JsonCodecable allows customizing the encoding of objects of a given class using a class-specific codec object, and JsonCodecable is an interface which is defined and can be used outside mediawiki core. In addition json-codec supports deserialization in the presence of aliased class names, fixing T353883. Backward and forward compatibility established via the mechanism described in https://www.mediawiki.org/wiki/Manual:Parser_cache/Serialization_compatibility Test data generated by this patch was added in I109640b510cef9b3b870a8c188f3b4f086d75d06 to ensure forward compatibility with the output after this patch is merged. Benchmarks: PHP 7.4.33 PHP 8.2.19 PHP 8.3.6 BEFORE AFTER BEFORE AFTER BEFORE AFTER Serialize: 926.7/s 1424.8/s 978.5/s 1542.4/s 1023.5/s 1488.6/s Serialize (assoc): 930.2/s 1378.6/s 974.6/s 1541.9/s 1022.4/s 1463.4/s Deserialize: 1942.7/s 1961.3/s 2118.8/s 2175.9/s 2129.8/s 2063.5/s Deserialize (assoc): 1952.0/s 1905.7/s 2107.5/s 2192.1/s 2153.3/s 2011.1/s These numbers definitely do not have as many significant digits as written here. But they should be sufficient to demonstrate that performance is not impaired by this patch and in fact serialization speed improves slightly. Bug: T273540 Bug: T327439 Bug: T346829 Bug: T353883 Depends-On: If1d70ba18712839615c1f4fea236843ffebc8645 Change-Id: Ia1017dcef462f3ac1ff5112106f7df81f5cc384f
