This reverts commit d0527427be.
This patch makes Swoole/Swow can not work anymore, because Coroutine will yield to another one during socket operation, EG(record_errors) assertion will always fail, and zend_begin_record_errors() was only used during compile time before.
Note: zend_emit_recorded_errors() and the typo fix are reserved.
This is not actually related to SSL handshake but stream socket creation
which does not clean errors if the error handler is set. This fix
prevents emitting errors until the stream is freed.
Currently, classes that can't be linked get moved back into the original script
and are not preloaded. As such classes may be referenced from functions that
did get preloaded, there is a preload autoload mechanism to load them at
runtime.
Since PHP 8.1, we can safely preload unlinked classes, which will then go
through usual lazy loading. This means that we no longer need the preload
autoload mechanism. However, we need to be careful not to modify any hash
table buckets in-place, and should create new buckets for lazy loaded classes.
Since 3e6b447979 it is again possible to have
warnings (deprecations) during inheritance, and more such functionality is
likely in the future. This is a problem, because such warnings will only be
shown on the first request if the opcache inheritance cache is used. This
currently causes test failures in --repeat builds.
Fix this by uplifting the error recording functionality from opcache to Zend,
and then using it to persist a warning trace in the inheritance cache, which
can then be used to replay the warnings on subsequent executions.
This is needed by both fibers and opcache (and GH-6903 also uses it),
so make it a common structure that can be used by any functionality
storing warnings/errors.
As debug_print_backtrace() is not performance-critical, this
implements it by formatting the zend_fetch_backtrace() result.
This means there is only one place implementing the backtrace
construction logic, and they cannot go out of sync.
zend_fetch_backtrace() has much better test coverage, because
it is used by exceptions.
Closes GH-6869.
