Apparently, some ICU versions report "America/Los_Angeles" for the `ZZ`
case, what matches the behavior of ICU 76.1 (on Windows). Possibly,
there has been some bug fix backport on some systems. Anyhow, either
seems fine, so we're not picky about that.
Closes GH-17669.
This is a follow-up on GH-17343 to implement GC cycle management.
Previously the objects lived too long due to the strong cycle.
This patch adds get_gc handlers to break the cycle.
Closes GH-17355.
The segfault happens because zoi->wrapping_obj points to an object that has been freed.
This wrapping_obj is set in IntlIterator_from_StringEnumeration().
Notice how the refcount is not increased in this function.
By switching to ZVAL_OBJ_COPY, the segfault disappears.
We also need to move the responsibility of destroying the iterator to
the iterator itself and keep the object data destruction in the object
destruction. The existing code used a weird recursive destruction
between the iterator and object that was too hard to understand to be
honest. This patch simplifies everything and in the process gets rid of
the leak.
Iterators that are embedded are now responsible for their own
memory cleanup.
Closes GH-17343.
Besides that just checking for icuuc.lib does not necessarily imply
that the other libraries are available, doing it this way will not copy
the PDBs to the build folder, so these are not available in the debug
packages. Furthermore, `CHECK_LIB` already adds the library to the
flags, so there is no need to do this manually.
Closes GH-17010.
To match other capitalized strings like `ZEND_STR_UNKNOWN_CAPITALIZED` and
`ZEND_STR_ARRAY_CAPITALIZED`. Since this known string was only added in PHP
8.4, no backwards compatibility alias is needed.
When functions' or class methods' 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 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.
This needs to be explicitly enabled for MSVC (and probably clang on
Windows); otherwise the default is C++14, which is no longer sufficient
for ICU[1].
While the official PHP 8.4 builds for Windows do not yet use ICU 75.1,
that may change[2]. And even if not, it would be nice for custom
builds to be able to build against ICU 75.1 (or later).
Anyhow, using `std:c++17` is fine for ICU 72.1 which we are currently
using (and likely for some older ICU versions).
