The entry.flags was used to check whether the entry has the directory
flag. The flags however were masked to only contain the permissions. We
need to check the mode, before the permission masking, instead of the
flags to check whether it is a directory.

memsize is a signed long, therefore the check against the
(*un*signed long maximum) / 1024² will allow too large values. This check worked
correctly in d4b3f89c53 where it checked against the maximum signed
value, but was broken in 003346c450. Fix it by changing ZEND_ULONG_MAX
to ZEND_LONG_MAX.
Generators that suspended a fiber should not be dtor because they will be
executed during the fiber dtor.
Fiber dtor throws an exception in the fiber's context in order to unwind and
execute finally blocks, which will also properly dtor the generator.
Fixes GH-9916
This debug code is part of arginfo validation. This validation will
never trigger properly because the OR operation makes the first if
always true. Fix it by changing to an AND.

The condition `code == 0x0450 || code == 0x045D` is always false because
of an incorrect range check on code.
According to the BMP coverage in the encoding spec for ISO-8859-5
(https://encoding.spec.whatwg.org/iso-8859-5-bmp.html) the range of
valid characters is 0x0401 - 0x045F (except for 0x040D, 0x0450, 0x045D).
The current check has an upper bound of 0x044F instead of 0x045F.
Fix this by changing the upper bound.

The current check always evaluated to false because if `!page_size`
is true, then `page_size & (page_size - 1)` equals `0 & (0 - 1)` which
is always 0. The if condition is meant to check if page_size is zero or
not a power of two, thus we must change the AND to an OR to fix this
issue.

The "nothing to do" case would never be hit because the switch block
would execute if the opcode is ZEND_ASSIGN_STATIC_PROP_OP,
not ZEND_ASSIGN_STATIC_PROP. This meant that we were falling through to
the else block. Fix this by correcting the check condition.
When a uint8_t is bitshifted to the left, it is actually promoted to an
int. For the current code this has the effect of a wrong sign-extension,
and the result will also wrongly become zero when insert_pos >= 32.
Fix this by adding an explicit cast.
Furthermore, the partial prefix byte mask was computed incorrectly: the
byte is already shifted so the mask should not account for the shift.
This effectively reverts #8984.
As discussed in #10327 which will enable the use of the getrandom(2) syscall on
NetBSD instead of relying on the userland arc4random_buf(), the CSPRNG should
prioritize security over speed [1] and history has shown that userland
implementations unavoidably fall short on the security side. In fact the glibc
implementation is a thin wrapper around the syscall due to security concerns
and thus does not provide any benefit over just calling getrandom(2) ourselves.
Even without any performance optimizations the CSPRNG should be plenty fast for
the vast majority of applications, because they often only need a few bytes of
randomness to generate a session ID. If speed is desired, the OO API offers
faster, but non-cryptographically secure engines.
The assertion failure was triggered in a debug code-path that validates
property types for internal classes.
zend_verify_internal_read_property_type was called with retval being a
reference, which is not allowed because that function eventually calls to
i_zend_check_property_type, which does not expect a reference.
The non-debug code-path already takes into account that retval can be a
reference, as it optionally dereferences retval.
Add a dereference in zend_verify_internal_read_property_type just before
the call to zend_verify_property_type, which is how other callers often
behave as well.
When this INI option is enabled, it reverts the line separator for
headers and message to LF which was a non conformant behavior in PHP 7.
It is done because some non conformant MTAs fail to parse CRLF line
separator for headers and body.
This is used for mail and mb_send_mail functions.
The condition `UNEXPECTED(Z_TYPE_P(key)) == IS_REFERENCE` always
returned false, because `UNEXPECTED(expression)` always returns 0 or 1.
Move the parens so the comparison is executed properly.
Closes GH-10332.
