This regressed in 62c7432f, prior to that commit the value was set to
false in case random number generation failed, but now even if an
exception is thrown it is set to true. This likely does not _really_
matter as the user will handle the exception, still the value in
$strong_result is observable.
The main purpose of this is to better handle the API difference and add
an inital work to separate PHP and OpenSSL logic. This is really just
the first step and further changes are coming after that.
Closes GH-16918
We prefer clean solutions (such as declaring the proper type in the
first place, or introducing a portable format specifier) where easily
possible, but resort to casts otherwise.
We also port f1480ab14b.
* PHP-8.3:
Fix memory leak in php_openssl_pkey_from_zval()
Fix various memory leaks related to openssl exports
Prevent unexpected array entry conversion when reading key
* PHP-8.2:
Fix memory leak in php_openssl_pkey_from_zval()
Fix various memory leaks related to openssl exports
Prevent unexpected array entry conversion when reading key
When passing an array, the key entry can get converted to a string if it
is an object, but this actually modifies the original array entry.
The test originally outputted:
```
array(2) {
[0]=>
string(...) => ...
[1]=>
string(0) ""
}
```
This is unexpected. Use zval_try_get_string() to prevent this behaviour.
Closes GH-16693.
The `offset_sec` parameter of `X509_gmtime_adj()` expects a `long`, but
the `$days` parameter of `openssl_csr_sign()` a `zend_long`. We must
avoid signed integer overflow (UB), but also must not silently truncate.
Thus we check the given `$days` for the permissible range, and bail out
otherwise.
Closes GH-16437.
We must not use `try_convert_to_string()` on members of unseparated
array arguments; instead of separating, we use `zval_try_get_string()`.
Closes GH-16370.
We change the error for ZTS builds to a warning, to not break snapshot
builds which automatically will try to enable OpenSSL password hashing.
We also change some messages to better fit building on Windows.
And of course, we cannot easily check whether `OSSL_set_max_threads()`
is actually available; instead we're looking up the function declaration
in its header file.

To match other capitalized strings like `ZEND_STR_UNKNOWN_CAPITALIZED` and
`ZEND_STR_ARRAY_CAPITALIZED`. Since this known string was only added in PHP
8.4, no backwards compatibility alias is needed.
This is not necessarily useful for Windows (few use custom builds on
that platform), but for feature parity with other platforms it seems
reasonable to support it on Windows.
We make sure, though, that the feature is not enabled for snapshot
builds by adding the option to the build exclusions.
When functions' or class methods' availability is based on some preprocessor
condition, the generated arginfo header files wrap the declarations in the
preprocessor `#if` conditional blocks, one per declaration, even if they are in
the same conditional block based on comments in the stub file. Instead of
having multiple conditional blocks one after the other with the same condition,
combine them into a single conditional block.
When a class (or enum) has no methods, rather than using an array that only
contains `ZEND_FE_END`, use `NULL` for the functions. The implementation of
class registration for internal classes, `do_register_internal_class()` in
zend_API.c, already skips classes where the functions are `NULL`. By removing
these unneeded arrays, we can reduce the size of the header files, while also
removing an unneeded call to zend_register_functions() for each internal class
with no extra methods.
Currently, internal classes are registered with the following code:
INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;
This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.
The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.
