JSON encode escape forward slash

Old and new behavior

By toggling the json_escape_forward_slash compat option, you can chose either the json encoder escapes the ‘/’ sign or it does not:

tarantool> require('compat').json_escape_forward_slash = 'old'
---
...

tarantool> require('json').encode('foo/bar')
---
- '"foo\/bar"'
...

tarantool> require('compat').json_escape_forward_slash = 'new'
---
...

tarantool> require('json').encode('foo/bar')
---
- '"foo/bar"'
...

The option affects both the global serializer instance and serializers created with json.new(). It also affects the way log messages are encoded when written to the log in the json format (the box.cfg.log_format option is set to ‘json’).

Known compatibility issues

At this point, no incompatible modules are known.

Detecting issues in your codebase

Both encoding styles are correct from the JSON standard standpoint, but if your module relies on encodings results bytewise, it may break with this change. Be cautious if you do the following:

• Hash results of json.encode().
