Currently compiler flags passed by extensions using the standard
``PHP_NEW_EXTENSION`` and ``PHP_ADD_SOURCES`` m4 macros are prepended
before the ones defined by ``Zend/Zend.m4``.
This was not really an issue before as ``Zend.m4`` only included
``-Wall`` but since the addition of ``-Wextra`` various issue about
disabling flags have been brought up.
A preliminary attempt was done in commit 5c1cf7669b
but this turns out to be more or less irrelevant.
The root issue is that ``PHP_NEW_EXTENSION`` and ``PHP_ADD_SOURCES`` call the
``PHP_ADD_SOURCES_X`` macro and pass their flags as the 3rd argument which prepends
the flags. There exists a 6th argument for this macro which appends them but from a
cursory look at https://heap.space/search?full=PHP_ADD_SOURCES_X&project=php-src
this is not used. Moreover, the comment describing this macro explicitly informs
that this macro should not be used directly.
As such we drop the 6th argument of ``PHP_ADD_SOURCES_X`` and move the `special-flags`
argument to be appended instead of prepended.

Use a separate "reverse" flag to determine search direction,
using offset == -1 to indicate this is is confusing. I initially
thought the code was trying to handle negative offsets.
Also deduplicate the forward and reverse cases, they really only differ
in one place.
The constructor was already effectively inaccessible (protected
on a final class). This just makes it more obvious and removes
the implementation in favor of directly throwing.
Per the removed test, this was an unfinished feature, and I don't
think it makes a lot of sense to finish it -- the
mysqli_stmt::get_warnings() interface makes more sense than
direct construction.
Closes GH-6208.
Remove inline.
Remove old folding blocks.
Convert an int usage to bool.
Convert some uses of int and size_t into zend_long. This is
incomplete because get_gc requires `int *n`, which should probably
become zend_long or size_t eventually.
Adds spl_fixedarray_empty to help enforce invariants.
Adds spl_fixedarray_default_ctor.
Documents some functions.
Reworks spl_fixedarray_copy into two functions:
- spl_fixedarray_copy_ctor
- spl_fixedarray_copy_range
I'm hoping to eventually export SplFixedArray for extensions to
use directly, which is the motivation here.
Remove arbitrary restriction that attributes cannot be applied
to property/constant groups.
The attribute applies to all elements of the group, just like
modifiers and types do.

Instead of setting the old AST type to zero, replace the AST with
the compiled constexpr AST zval. This requires passing in a
zend_ast** instead of a zend_ast*.
This allows compiling ASTs containing constexprs multiple times
-- the second time, the existing compiled representation will be
resused.
This means we no longer need to copy the attributes AST for
promoted properties.
Make ReflectionAttribute::newInstance() respect the strict_types=1
declaration at the attribute use-site. More generally, pretend that
we are calling the attribute constructor from the place where the
attribute is used, which also means that the attribute location will
show up properly in backtraces and inside "called in" error information.
This requires us to store the attributes strict_types scope (as flags),
as well as the attribute line number. The attribute filename can be
recovered from the symbol it is used on. We might want to expose the
attribute line number via reflection as well.

The motivation for this change is to prevent extensions from having to check executor globals for the current execute_data during function call init. A previous implementation of the observer API initialized the function call from runtime cache initialization before execute_data was allocated which is why zend_function was passed in.
But now that the observer API is implemented via opcode specialization, it makes sense to pass in the execute_data. This also keeps the API a bit more consistent for existing extensions that already hook zend_execute_ex.
Closes GH-6209
To make things a bit less weird, split off the function name into
a zval stored separately from the arguments. This allows us to
use normal zpp and get standard behavior.
The 32-bit tests work on both 32-bit and 64-bit. I dropped the
64-bit variants as they only test one additional case that I don't
think adds particular value.
Make the behavior of substr(), mb_substr(), iconv_substr() and
grapheme_substr() consistent when it comes to the handling of
out of bounds offsets. substr() will now always clamp out of
bounds offsets to the string boundary. Cases that previously
returned false will now return an empty string. This means that
substr() itself *always* returns a string now (like mb_substr()
already did before.)
Closes GH-6182.
This patch fixes some problems with preprocessing SQL queries.
* The new algorithm takes into account single-line and multi-line
comments and ignores the ":" and "?" Parameter markers in them.
* The algorithm allows the EXECUTE BLOCK statement to be processed
correctly. For this statement, it is necessary to search for
parameter markers between EXECUTE BLOCK and AS, the rest should be
left as is.
The SQL preprocessing code has been ported from Firebird to handle
EXECUTE STATEMENT.
Closes GH-4920.
It is mandatory to pass either `SQL_NO_NULLS` or `SQL_NULLABLE` as
tenth parameter to `SQLSpecialColumns()`; otherwise the function call
fails. Therefore the user must be allowed to pass the desired value
as parameter to `odbc_specialcolumns()` again.
Closes GH-6200.
Noticed this while working on attributes strict_types handling.
We sometimes insert dummy frames internally, but I don't think
these should show up in debug_backtrace output unless they're
needed, either to display an include call or to preserve file/line
information that would otherwise get lost.
Closes GH-6195.
