Strangely, uses of eval and 'php -a' (or loading a file without opcache after a namespaced constant was declared)
will not treat non-FQ true/false/null as magic keywords, while compiled php required from a file would do that.
This may confuse people learning the language, and result in code loaded with
eval() behaving differently from the same snippet in a file loaded by require.
```
Interactive shell
php > define('foo\true', 'test');
php > namespace foo { var_dump(true); }
string(4) "test"
```
This will make the same session instead properly emit `bool(true);` like it
already would if running those statements in files when opcache was used.
When adding the #[ReturnTypeWillChange] attribute in namespaced
code, you also need to use ReturnTypeWillChange, otherwise it
will be silently ignored and may result in confusion. Change the
deprecation message to suggest #[\ReturnTypeWillChange], which
will always work.
Closes GH-7454.
We need to allocate buffers for the file mapping names which are large
enough for all potential keys (`key_t` is defined as `int` on Windows).
Regarding the test: it's probably never a good idea to use hard-coded
keys (should always use `ftok()` instead), but to reliably reproduce
this Windows specific issue we need to, and it shouldn't be an issue on
that OS.
Closes GH-7448.
If buf_len is zero, this would leave behind a dangling pointer
to an already released header.str. Make sure this can't happen
by always overwriting the pointer.
Closes GH-7376.
The CURLOPT_DEBUGDATA will point to the old curl handle after
copying. Update it to point to the new handle.
We don't separately store whether CURLINFO_HEADER_OUT is enabled,
so I'm doing this unconditionally. It should be harmless if
CURLOPT_DEBUGFUNCTION is not used.
Currently, resource IDs are limited to 32-bits. As resource IDs
are not reused, this means that resource ID overflow for
long-running processes is very possible.
This patch switches resource IDs to use zend_long instead, which
means that on 64-bit systems, 64-bit resource IDs will be used.
This makes resource ID overflow practically impossible.
The tradeoff is an 8 byte increase in zend_resource size.
Closes GH-7436.
