Proposal: new implentation of JSON extension.

Raise again this discussion as no feedback on pecl ML. Trying to solve https://bugs.php.net/bug.php?id=63520 I start to work on a dropin alternative for current json extension in php. Current work: https://github.com/remicollet/pecl-json-c It is obviously to late for PHP 5.5, and need probably more feedback, more tests, and more work before a RFC for PHP 5.6 (or later). * json_encode : same code than php 5.5, no difference * json_decode : wrapper over json-c 0.11 library. Difference: - error code returned by the parser are different (so only PHP_JSON_ERROR_SYNTAX and PHP_JSON_ERROR_DEPTH are used) - number only parse as integer (no automatic cast to double) - loose of performance (but still acceptable, I think) New feature: as json-c is an incremental parser, a new class is available to allow incremental parsing (for large json encoded data) Proposal: 1/ update existing pecl/json extension - on pecl for older PHP 5.3 - 5.5 - on php-src in master / 5.6 OR 2/ new pecl/json-c extension - PHP will keep the non free code Should I open a RFC ? Regards, Remi. P.S. I have tried to contact Omar, original author of this extension, without any success.
