Fixes #267.

This PR includes the following changes:

  • Remove obsolete locking macros (https://www.seidengroup.com/2020/12/07/porting-extensions-to-php-8/, hat tip to @frost-byte)
  • Update some calls that now take a zend_object * instead of a zval *
  • Add now-required arginfo for a lot of methods that do not take any arguments
  • Remove an obsolete reference to PHP versions earlier than 7.0
  • Add CI for PHP 8.0
  • Remove CI for older versions of PHP, as the extensions contains backward-incompatible changes
  • Update all tests for compatibility with PHPUnit 9
  • Update composer.json for compatibility with PHP 8 and some newer package versions
  • Skip two failing integration tests

Once this is merged, I recommend tagging a 0.7.0 release. Note that that release will no longer be compatible with PHP 7, as PHP 8 introduced a bunch of backwards-incompatible changes to interfaces used by this extension.

Merging this PR will resolve a bunch of issues in this repo (formatted so that GitHub can parse them):

Note that compiling the extension unit tests passes; the build failure seems due to unrelated code coverage issues with PHPUnit.

For what it's worth, this patch does compile nicely on 8.0.3 👍 (working on other non related php8 compat until i can test this properly)

This shouldn't be nesssary, nothing happens in setUp of the parent test case.

It's good practice. Avoids nasty surprises if stuff later does get added to the parent implementation of setUp.

I disagree with this strongly, it's confusing because it implies that something's being called in the setUp method. If ever this class gets extended (which is highly unlikely), it's very obvious to the person making the change that such logic would need to be added here (if the extended class contained the same methods). That's basic programming IMHO and does not need an attempt at future-proofing.

Also, this is a test class, so the risk is very small.

@bshaffer PTAL. I have added integration tests for PHP 7.4 now (including WordPress), but I'd like to keep the parent::setUp calls to avoid nasty surprises if stuff later does get added to the parent implementation of setUp.

Once the unnecessary parent calls are removed, this is LGTM from the PHP-side for me. We will still need @chingor13 to sign off on the C-side

Never mind, only saw your comments on that now. Will remove those tomorrow.

I know it's a nit, so thank you!

@bshaffer removed the parent calls now, PTAL :-)

Would you mind pinging chingor13 to have a look at the C part? I'd like to get this merged soon, if possible.

Thanks @bshaffer! It would be great if someone with the appropriate permissions (probably @chingor13) could also update the package on PECL; it hasn't been updated in a while (also see #243 and #252).

0.3.0 should be available on PECL
