Replacing the result type in the general case is dangerous,
because not all opcodes support both VAR and TMP. One common case
is the in_array() result being passed to SEND_VAR, which would
have to be changed to SEND_VAL.
Rather than complicating this logic, reduce the scope to only
doing the type replacement for JMPZ and JMPNZ. The only reason
we're doing this in the first place is to enable the smart branch
optimization, so we can limit it to the relevant opcodes. Replacing
the result type may be marginally useful in other cases as well
(as it may avoid reference checks), but not worth the bother.
We only need to reject functions that could warn (or have runtime
dependent behavior). If a function can throw in some cases, just
let it and discard the result.
We should clear the exception *before* we destroy the execute_data.
Add a variation of the test that indirects through another file,
and would crash otherwise.
MySQL removed RENAME DATABASE in 18300001c1dbbfddf9a0adcbaeea68956102bdd0
(Sept 2007, 5.1.23). As this briefest existance is very insignificant lets remove it.
It also breaks when testing against MariaDB.
As the alternate path in this test covers all supported MySQL and MariaDB
versions and a signifant portion of unsupported versions lets keep it simple.
Closes GH-6459.
While the use of zend_cpu_supports_*() is only strictly necessary
inside ifunc resolvers, where the cpu state has not been initialized
yet, we should prefer the compiler builtins in all cases.
Rename the methods in MessageFormatAdapter to make sure they don't
clash with anything defined by icu itself, which may be a problem
if icu is linked statically.
References to null-serializations are stored as null, and as such
are part of the reference count.
Reminds me that we really need to deprecate the mess that is
Serializable.
Handle one case the previous patch did not account for: If
unserialization of data fails, we should still register a ref
source.
Also add an extra test for a reference between two typed properties,
as this used to be handled incorrectly earlier.
Reindent ext/mysqli tests on PHP-7.4, so they match with the
indentation on PHP-8.0. Otherwise merging test changes across
branches is very unpleasant.
Only register the slot for adding ref sources later if we didn't
immediately register one. Also avoids leaking a ref source if
it is added early and the assignment fails.
Fixes oss-fuzz #27628.
The name "rem_size" is used by a macro in a system header on AIX,
specifically `sys/xmem.h`. Without changing the name, you get the
name mangled like so:

This just renames the variable so that it won't trip on this
definition. Tested to fix the build on IBM i PASE.
Closes GH-6453.
Make sure the $PHP_THREAD_SAFETY variable is always available
when configuring extensions. It was previously available for
phpized extensions, but for in-tree builds it was being set
too late.
Then, use $PHP_THREAD_SAFETY instead of $enable_zts to check for
ZTS in bundled extensions, which makes sure these checks also
work for phpize builds.
Use $PHP_THREAD_SAFETY instead of $enable_zts to check for ZTS.
This variable is also available for phpize builds, while enable_zts
is only present for in-tree builds.
In the somewhat unlikely case that `zend_fstat()` fails, we must not
proceed executing the function, but return `false` instead.
Patch based on the patch contributed by sagpant at microsoft dot com.
Closes GH-6432.
For a division like [1..1]/[2..2] produce [0..1] as a result, which
would be the integer envelope of the floating-point result.
The implementation is pretty ugly (we're now taking min/max across
eight values...) but I couldn't come up with a more elegant way
to handle this that doesn't make things a lot more complex (the
division sign handling is the annoying issue here).
