Replace lemon-generated JSON parser with simpler recursive descent parser
-------------------------------------------------------------------------
Key: AVRO-268
URL: https://issues.apache.org/jira/browse/AVRO-268
Project: Avro
Issue Type: Improvement
Components: c
Reporter: Matt Massie
Fix For: 1.3.0
This is a drop-in replacement for the current JSON parser which is based on
lemon (a LALR parser generator).
This parser
* reads and returns a single JSON_value and its nested children (using
recursive descent parsing)
* allows you to process JSON from streams in addition to static memory buffers
* correctly processes unicode \u escaping including surrogates
* distinguishes between integer and real number representations
* provides information about the line and character in JSON that failed to parse
* is much simpler to understand and maintain (less lines of code and source
files)
* is written to allow error recovery to be added later
This patch also adds more unit tests.
