`php_stream_can_cast()` forwards to `_php_stream_cast()` with `ret` set
to `NULL`. `php_pgsql_fd_cast()` needs to cater to that, because
otherwise the stream would report that it is not castable.
This *might* fix https://bugs.php.net/73903.
Closes GH-6888.
* Prevents some unnecessary strlen() computation
* Use interned "NULL"
* Certain PGSQL_API functions now accept zend_string* instead of char*
Closes GH-6792
Version numbers are not supposed to be localized, so we must not apply
locale dependent parsing with `atof()`.
Using `php_version_compare()` might even be better.
Closes GH-6668.
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.
Historically, the _ex variants separated the zval first, if a
conversion was necessary. This distinction no longer makes sense
since PHP 7.
The only difference that was still left is that _ex checked whether
the type is the same first, but the usage of these macros did not
actually distinguish on whether such an inlined check is valuable
or not in a given context.
Also drop the unused convert_to_explicit_type macros.
This testing mode executes the test multiple times in the same
process (but in different requests). It is primarily intended to
catch tracing JIT bugs, but also catches state leaks across
requests.
Closes GH-6365.
This is an error that slipped in via 8d37c37bcd.
pg_unescape_bytea() did not accept null in PHP 7.4, and it is not
meaningful for it to accept null now -- it will always fail, and now
with a misleading OOM message.
Add some tests to cover related codepaths.
With the small caveat that the ones in build_assignment_string()
still don't seem to be tested as it looks the condtions are checked
beforehand, might need some more investigation.
Closes GH-6226
The same error condition is a ValueError in mysqli, be consistent.
Additionally, do not display the argument name for these errors.
As the signatures are overloaded, the argument name may not match
the meaning at all.
The implementation did not check for PQunescapeBytea failure
correctly, because it checked for a null pointer after estrndup,
which certainly cannot happen. Inspection of the PGunescapeBytea
implementation has shown that this function can only fail on OOM,
so let's check for that explicitly and remove false as a possible
return type.
While we're here, avoid an unnecessary copy of the result.
