Since the constructor of DirectoryIterator and friends is supposed to
accepts paths (i.e. strings without NUL bytes), we must not accept
arbitrary strings.
Also generate a fatal error if a collision occurs in zend_compile.
This is not perfect, because collisions might still be introduced
via opcache, if one file is included multiple times during a request,
invalidate in the meantime and recompiled by different processes.
This still needs to be addressed, but this patch fixes the much
more common case of collisions occuring when opcache is not used.
Fixes bug #78903.
We need to make sure that trait methods with static variables
allocate a separate MAP slot for the static variables pointer,
rather than working in-place.
This assumes that `iterator_*` will now always throw or abort on failure.
Also, move #include _arginfo.h directive to the top of the file - virtually all
other files put it there, and developers may base code on basic_functions.c.
Closes GH-4968
Use zend_hash_update instead of zend_hash_add.
These are taking a subset of keys from an array with unique keys,
so the result should also have unique keys.
(this is already done for array_map())
Also, speed up array_intersect and array_diff slightly by
using ZEND_HASH_FOREACH macros.
This way, it doesn't need to load the same buckets and array counts
from memory every time (compiler previously couldn't infer they won't change)
```php
<?php
// $n=10000 now takes 0.095 seconds instead of 0.102
function test_bench(int $n) {
$values = range(0,1000);
$other = range(0,1000);
unset($other[500]);
unset($values[400]);
$total = 0;
for ($i = 0; $i < $n; $i++) {
$total += count(array_intersect_key($values, $other));
}
return $total;
}
```
