json_normalize / json_equals - unnecessary double parsing JSON document - performance

    XMLWordPrintable

Details

    Description

      json_normalize, the C function used by JSON_NORMALIZE and JSON_EQUALS, calls json_valid before processing. The processing reparses the same json document that json_valid already processed.

      Beginning of patch attached, just need to complete within json_normalize.c to ensure that the error handling is pristine.

      relevant tests:

      • main.json_normalize
      • main.json_equals
