PHP 8.0 compatibility #172
Conversation

Thank you for the patches! The first patch corresponds to the native-tls proposal and 1.c bullet ('TSRM changes') of the PHP 8.0 UPGRADING.INTERNALS document. It looks okay. Those macros are no-op since PHP 7.0, so we can just remove them. We can push this minimal change (define as no-op) and remove them later, though. The second patch corresponds to the negative_array_index proposal. There is no related entry in the PHP 8.0 UPGRADING.INTERNALS document, but the change is the following: php/php-src#3772. (It is strange that the problem stated as relevant only to PHP 8.1 in #170 (comment). It also affects PHP 8.0 according to php-src git logs and results of my local testing.) I don't completely understand the php-src change, but our side fix looks working. I'll do the following:
When time will permit I would also do: |
The TSRM* macros are no-op since PHP 7.0. PHP 8.0 drops them at all. Define them as no-op in our code when building against PHP 8 and newer to overcome a build fail. See [1] and [2] (1.c) for details. Those macros could be removed from the code entirely (both definitions and usages), since we support PHP 7.0+. It is to be done later.

NB: PHP 8.1 introduces |
The `nNextFreeElement` field is initialized with `ZEND_LONG_MIN` instead of zero since PHP 8.0. Adjust our `php_mp_is_hash()` check accordingly. See [1] and [2] for details. NB: PHP 8.1 introduces `zend_array_is_list()`, which may be used here. See [3] and [4] for details. [1]: https://wiki.php.net/rfc/negative_array_index [2]: php/php-src#3772 [3]: https://wiki.php.net/rfc/is_list [4]: php/php-src#6070 Since I don't observe any other problems on PHP 8.1, closing the relevant issue. Fixes tarantool#171
Hopefully, 8.1 as well. At least, the tests on 8.1 pass
