`spl_object_storage_attach_handle` creates an entry already, but only
fills it in at the end with `spl_object_storage_create_element` which
allocates memory. In this case the allocation fails and we're left with
a NULL slot. Doing the allocation first isn't an option because we want
to check whether the slot is occupied before allocating memory.
The simplest solution is to set the entry to NULL and check for a NULL
pointer upon destruction.
Closes GH-14849.
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

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.
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.
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.
This merges all usages of emitting an offset TypeError into a new ZEND_API function
zend_illegal_container_offset(const zend_string* container, const zval *offset, int type);
Where the container should represent the type on which the access is attempted (e.g. string, array)
The offset zval that is used, where the error message will display its type
The type of access, which should be a BP_VAR_* constant, to get special message for isset/empty/unset
