Ensure that the "creating default object from empty value" warning is
always thrown. Previously some cases were missing the warning, in
particular those going through FETCH_OBJ_W rather than a dedicated
opcode (like ASSIGN_OBJ).
One slightly unfortunate side-effect of this change is that something
like $a->b->c = 'd' will now generate two warnings rather than one
when $a is null (one for property b, one for property c).
Contrary to the comments, these only hide constructors (old or new
style) if they a) are inherited b) come from a trait and c) are
aliased -- which doesn't make any sense at all.
The ext/date/lib is bundled library and also includes additional
timelib.m4 macros and checks specific for PHP.
All the checks in the timelib.m4 are already done in the PHP's
configure.ac:
- headers except for io.h and strings.h
- two functions checked strftime and gettimeofday
- if size of longint is 8
- if size of int is 4
- int32_t and uint32_t types using the PHP_CHECK_STDINT_TYPES
Macro `AC_TIMELIB_C_BIGENDIAN` defined in timelib.m4 is not used.
The two checkings for strtoll and atoll have been moved to date extension's
config0.m4 file.
Additional check for headers <io.h> and <strings.h> has been added to
config0.m4 of the date extension.
Therefore the timelib.m4 can be simplified and removed from the bundled
library to have easier maintenance in the later branches and also
upstream library.
As discussed in bug #77580, passing INVALID_HANDLE_VALUE for the
completion event improves compatibility with Wine/ReactOS. The timer
callback itself is supposed to complete fast enough, no behavior change
is to expect.
SO_USER_COOKIE primarly to be traced via dtrace instrumentation.
If SO_USER_COOKIE is available, the rest is so the former is
two years old while the rest is from around 2008.
get_properties() constructs these as fresh objects with no relation
to the internals, there is no need to clone them again. Additionally
the current implementation leaks memory, because the original objects
are never freed (see PR #3121).
The memory leak occurs when more than one UserComment tag is present in
the EXIF data. It's still considered corrupt EXIF data, but this ensures
the memory is freed before trying to set to already allocated memory.
