Prefer:
ZEND_PARSE_PARAMETERS_NONE();
Over:
if (zend_parse_parameters_none() == FAILURE) {
RETURN_THROWS();
}
It's shorter, more modern, and they do the same thing. Technically,
ZEND_PARSE_PARAMETERS_NONE doesn't check that there's an exception,
but it generates one, so it's still cohesive.
Previously this returned `int`. Many functions actually take advantage
of the fact this returns exactly 0 or 1. For instance,
`main/streams/xp_socket.c` does:
sockopts |= STREAM_SOCKOP_IPV6_V6ONLY_ENABLED * zend_is_true(tmpzval);
And `Zend/zend_compile.c` does:
child = &ast->child[2 - zend_is_true(zend_ast_get_zval(ast->child[0]))];
I changed a few places trivially from `int` to `bool`, but there are
still many places such as the object handlers which return `int` that
should eventually be `bool`.
* 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
php_pcre_replace_impl() can fail and return NULL. We should take that
error condition into account. Because other failures return false, we
return false here as well.
At first, I also thought there was a potential memory leak in the error
check of replacement_str, but found that the error condition can never
trigger, so replace that with an assertion.
Closes GH-14292.
* Update signature of pcre API
This changes the variables that are bools to actually be bools instead
of ints, which allows some additional optimization by the compiler (e.g.
removing some ternaries and move extensions).
It also gets rid of the use_flags argument because that's just the same
as flags == 0. This reduces the call frame.
* Use zend_string_release_ex where possible
* Remove duplicate symbols from strchr
* Avoid useless value conversions
* Use a raw HashTable* instead of a zval
* Move condition
* Make for loop cheaper by reusing a recently used value as start iteration index
* Remove useless condition
This can't be true if the second condition is true because it would
require the string to occupy the entire address space.
* Upgrading + remark
This reallocates the PHP array when one can just use the named_params fields to pass the positional arguments instead.
Only usage of zend_fcall_info_args(_ex) remains in PDO.
This reverts commit 94ee4f9834.
The commit was a bit too late to be included in PHP 8.2 RC1. Given it's a massive ABI break, we decide to postpone the change to PHP 8.3.
We need to prevent integer overflow to eventually stop the iteration.
A test case doesn't appear sensible for this, because even on 32bit
architectures a respective test easily runs for a few minutes.
Closes GH-8447.
This fixes GH-7774.
spl_iterators.h was including php_pcre.h so that one object intern struct could
reference a pcre_cache_entry. These object interns should not be public, so they
can be moved out of the header file.
This change moves the object interns ouf of spl_iterators.h so that php_pcre.h
doesn't need to be included from there.
