When a class (or enum) has no methods, rather than using an array that only
contains `ZEND_FE_END`, use `NULL` for the functions. The implementation of
class registration for internal classes, `do_register_internal_class()` in
zend_API.c, already skips classes where the functions are `NULL`. By removing
these unneeded arrays, we can reduce the size of the header files, while also
removing an unneeded call to zend_register_functions() for each internal class
with no extra methods.
Currently, internal classes are registered with the following code:
INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;
This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.
The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.
* Include from build dir first
This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.
Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :
-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/
As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.
After this change, the include path is defined as follows:
-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
* Fix extension include path for out of tree builds
* Include config.h with the brackets form
`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.
Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.
* Mark many functions as static
Multiple functions are missing the static qualifier.
* remove unused struct sigactions
struct sigaction act, old_term, old_quit, old_int;
all unused.
* optimizer: minXOR and maxXOR are unused
In the same time, let's not verify implementation aliases since they may now legitimately differ from their aliased function/method counterparts (think about the ext/dom refactoring where e.g. many return type declarations have changed). Additionally, unnecessary `@no-verify` tags are cleaned up.
* Remove always-true stmt_obj->db_obj condition
This is always true because SQLITE3_CHECK_INITIALIZED checks this.
* Remove always-true param_number check
This is always true because we return early when the value < 1.
Removes 'PRAGMA writable_schema;'.
From sqlite changelog https://www.sqlite.org/releaselog/3_44_0.html:
> The SQLITE_DBCONFIG_DEFENSIVE setting now prevents PRAGMA writable_schema
> from being turned on.
> Previously writable_schema could be turned on, but would not actually allow
> the schema to be writable. Now it simply cannot be turned on.
Closes GH-12636.
In this test file, the free_obj handler is called with a refcount of 2,
caused by the fact we do a GC_ADDREF() to increase its refcount while
its refcount is still 1 because the Foo object hasn't been destroyed yet
(due to the cycle caused by the sqlite function callback).
Solve this by introducing a get_gc handler.
Closes GH-11881.
It looks like sqlite3_step can vary quite drastically from one request to the
next. This seems to be caused by more or fewer calls to sqlite3VdbeSorterWrite.
It would be great if we could find a way to make execution of this function more
consistent, but at this point I don't know how.
Closes GH-12130
