`buf` may contain NUL bytes, so we must not use `strcspn()` but rather
a binary safe variant. However, we also must not detect a stray CR as
line ending, and since we only need to check line endings at the end
of the buffer, we can nicely optimize.

This optimization is targeting cases when a SplPriorityQueue instance is used
exclusively with double or long priorities.
During the first insertion into an empty queue, the comparator is changed to
the specialized one if the priority of inserted inserted key is long or double.
During insertion to non-empty queue, comparator is swapped back to the generic
one on type conflict.
As a result code like following, where the weight field is always double or
int, runs almost twice as fast.
foreach ($items as $item) {
$pqueue->insert($item, -$item->weight);
if ($pqueue->count() > $size) {
$pqueue->extract();
}
}

* tidy - also removed a check for an ancient dependency version
FilesystemIterator::FOLLOW_SYMLINKS is currently treated as a directory
key mode flag, even though it does not change the way that the key
during iteration is set. To address this, FOLLOW_SYMLINKS has been
converted into an OTHER flag.
Closes GH-6695.
We need to always destroy current, not just when iter.data is not
set.
Take this opportunity to clean up the iterator destructor code a
bit, to remove redundant checks and incorrect comments.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

This makes --verify also check @implementation-alias. Failures are
ignored using @no-verify instead. Some mistakes have been made that
would have been caught by this...

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
The name doesn't correspond to what it does at all, and all the
existing usages appear to be unnecessary.
Usage of this macro can be replaced by ZVAL_DEREF + Z_TRY_ADDREF_P.
Introduced by the recent switch to a zend_object. Unserialize the
object into a tmp_var to avoid leaving behind a stack reference.
Fixes oss-fuzz #29271.
Track an 8-byte pointer as the key instead of 16-byte zval.
(4 byte on 32-bit builds)
The memory used for a set of 1 million objects decreased from
114 MiB to 106 MiB.
Use the new `Z_PARAM_*` APIs to parse the `zend_object*` pointer directly
Closes GH-6566
This decreases the memory usage of SplFixedArrays by 32 bytes per object
on 64-bit systems (use 1 null pointer instead of 5 null pointers)
If allocating a lot of arrays of size 1, memory usage was 19.44MiB before this
change, and 16.24MiB after the change.
Existing tests continue to pass.
Subclassing SplFixedArray is already inefficient and rarely done.
It checks for the existence of 5 methods every time a subclass is instantiated.
(and has to switch back from C to the php vm to call those methods)
Closes GH-6552
