These Autoconf macros have been marked as obsolete in PHP-8.4 and now
also removed:
- PHP_AP_EXTRACT_VERSION
- PHP_BUILD_THREAD_SAFE
- PHP_DEF_HAVE
- PHP_OUTPUT
- PHP_TEST_BUILD
During persisting, the JIT may trigger and fill in the call graph.
The call graph info is allocated on the arena which will be gone after preloading.
To prevent invalid accesses during normal requests, the arena data should be cleared.
This has to be done after all scripts have been persisted because shared op arrays between
scripts can change the call graph.
Closes GH-18916.
DL_LOAD now doesn't use RTLD_DEEPBIND deepbind anymore on platforms
where dlmopen with LM_ID_NEWLM is available:
this means shared library symbol isolation (if needed) must be enabled on
the user side when requiring libphp.so, by using dlmopen with LM_ID_NEWLM
instead of dlopen.
RTLD_DEEPBIND is still enabled when the Apache SAPI is in use.
Closes GH-10670.
ZEND_FUNC_INFO() can not be used on internal CE's. If preloading makes a
CE that's an alias of an internal class, the invalid access happens when
setting the FUNC_INFO.
While we could check the class type to be of user code, we can just skip
aliases altogether anyway which may be faster.
Closes GH-18915.
Clearly nobody has used this in a while given the compile errors and
warnings.
This patch fixes them so there are no errors nor warnings anymore.
Closes GH-18910.
This is necessary because the VM frees operands with the nogc variants. We
cannot just call gc_possible_root() because the object may no longer exist at
that point.
Fixes GH-18907
Closes GH-18917
similar to what have been done for pdo/sqlite as having statement
explain support to simulate how a query would operate or
for more advanced users, analysing the VM routines used
for possible optimisations.

When global constants' or class constants' availability is based on some
preprocessor condition, the generated arginfo header files wrap the
declarations in the preprocessor `#if` conditional blocks, one per declaration,
even if they are in the same conditional block based on comments in the stub
file. Instead of having multiple conditional blocks one after the other with
the same condition, combine them into a single conditional block.
When system is detected as big endian this enables the TSRM Local
Storage static cache with the ZEND_ENABLE_STATIC_TSRMLS_CACHE
compilation flag. Previously it was enabled only on little endian
systems.
The /d2FuncCache1 compile option is already added by
toolset_setup_common_cflags() in confutils.js to all targets.
ZEND_DVAL_TO_LVAL_CAST_OK was removed in
3725717de1.
We prevent signed overflow by making the count unsigned. The actual
interpretation of the count doesn't matter as it's just used to denote a
limit.
The test output for some limit values looks strange though, so that may
need extra investigation. However, that's orthogonal to this fix.
Closes GH-18906.
