1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
Prefer '%define api.value.type' to '#define YYSTYPE', so that Bison
know the type.
Use '%code requires' to declare what is needed to define the api.value.type
(that code is output in the generated header before the generated
definition of YYSTYPE).
Prefer '%define api.prefix' inside the grammar file to '-p' outside,
as anyway the functions defined in the file actually use this prefix.
Prefer `%param` to both `%parse-param` and `%lex-param`.
Closes GH-5138
The annotation %empty is properly enforced: warnings when it's
missing, and errors when it's inappropriate. Support for %empty was
introduced in Bison 3.0.
Pass -Wempty-rule to Bison.
Closes GH-5134
Use the shared empty array from ZVAL_EMPTY_ARRAY
For code that created an 10 arrays of 100000 empty arrays
(has the same result with `$assoc=true` and `{}`)
- This is the worst-case comparison, but I'd expect 0-length arrays to be fairly
common in regular data for json_decode
- The parser implementation was using function pointers so that third party
extension developers could reuse the json parser for their own
data structures, etc. (I think).
This PR is meant to let those third party extensions continue working
without changes.

Closes GH-4861.
Don't use <value> type for JSON tokens that don't have a value
and remove the errlex productions -- we're going to get an
unexpected token error anyway, there's no need to handle these
explicitly.
This also removes the awkward workarounds for the unused value
warnings.
With Bison 3.0 some directives are deprecated:
- %name-prefix "x" should be %define api.prefix {x}
- %error-verbose should be %define parse.error verbose
Bison 3.3 also started emiting more warnings and since PHP souce parsers
are not POSIX compliant this patch fixes this as pointed out via
495a46aa1d.
This commit is just a slight modification (renaming and some small
changes) of the patch that has been provided by Andrey Hristov.
It adds support for hooking of the json parser operations and
allows re-using of modified JSON parsing outside of json ext.
