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.
* Include the source location in Closure names
This change makes stack traces involving Closures, especially multiple
different Closures, much more useful, because it's more easily visible *which*
closure was called for a given stack frame.
The implementation is similar to that of anonymous classes which already
include the file name and line number within their generated classname.
* Update scripts/dev/bless_tests.php for closure naming
* Adjust existing tests for closure naming
* Adjust tests for closure naming that were not caught locally
* Drop the namespace from closure names
This is redundant with the included filename.
* Include filename and line number as separate keys in Closure debug info
* Fix test
* Fix test
* Include the surrounding class and function name in closure names
* Fix test
* Relax test expecations
* Fix tests after merge
* NEWS / UPGRADING
Regressed in 6fbf81c.
There is a missing error check on spl_filesystem_file_read_line(), which
means that if the line could not be read (e.g. because we're at the end
of the file), it will not set intern->u.file.current_line, which will
cause a NULL pointer deref later on.
Fix it by adding a check, and reintroducing the silent flag partially to
be able to throw an exception like it did in the past.
Closes GH-13692.
In the same time, let's not verify implementation aliases since they may now legitimately differ from their aliased function/method counterparts (think about the ext/dom refactoring where e.g. many return type declarations have changed). Additionally, unnecessary `@no-verify` tags are cleaned up.
When unserializing, the cached_resize field was not reset to -1
correctly, causing the setSize() method to think we were inside of a
resize operation.
Closes GH-13543.
* 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
When you do an assignment between two zvals (no, not zval*), you copy
all fields. This includes the additional u2 data. So that means for
example the Z_NEXT index gets copied, which in some cases can therefore
cause a cycle in zend_hash lookups.
Instead of doing an assignment, we should be doing a ZVAL_COPY (or
ZVAL_COPY_VALUE for non-refcounting cases). This avoids copying u2.
Closes GH-12086.
Upon resizing, the elements are destroyed from lower index to higher
index. When an element refers to an object with a destructor, it can
refer to a lower (i.e. already destroyed) element, causing a uaf.
Set refcounted zvals to NULL after destroying them to avoid a uaf.
Closes GH-11959.
We may OOM during object initialization. In this case, free_obj needs to guard
against NULL values. There may be more cases where this is an issue, these were
the ones I was able to discover via script.
Fixes GH-11734
