Máté Kocsis 663536d7d9 Improve class inheritance error messages (#7307) 2021-07-27 09:42:37 +02:00
Nikita Popov 814a932734 Add ZEND_ACC_NOT_SERIALIZABLE flag 
This prevents serialization and unserialization of a class and its
children in a way that does not depend on the zend_class_serialize_deny
and zend_class_unserialize_deny handlers that will be going away
in PHP 9 together with the Serializable interface.

In stubs, `@not-serializable` can be used to set this flag.

This patch only uses the new flag for a handful of Zend classes,
converting the remainder is left for later.

Closes GH-7249.
Fixes bug #81111.

Nikita Popov de6e401e05 Use common formatting for backtraces (#6977) 
This makes debug_print_backtrace() use the same formatting as exception
backtraces. The only difference is that the final #{main} is omitted,
because it wouldn't make sense for limited backtraces, and wasn't there
previously either.

Nikita Popov 4411026217 Close generator already in dtor phase 
In the added test case, the Closure ends up being freed before
the generator during GC.

This patch closes the generator (and thus releases the held
closure / execute_data) already during dtor_obj, which will avoid
ordering issues in free_obj. dtor_obj is not always called, but
if it isn't, then we also won't run GC and will free_obj in
reverse construction order.

Fixes oss-fuzz #33947.

Nikita Popov dd4a080133 Simplify and fix generator tree management 
This makes a number of related changes to the generator tree
management, that should hopefully make it easier to understand,
more robust and faster for the common linear-chain case. Fixes
https://bugs.php.net/bug.php?id=80240, which was the original
motivation here.

 * Generators now only add a ref to their direct parent.
 * Nodes only store their children, not their leafs, which avoids
   any need for leaf updating. This means it's no longer possible
   to fetch the child for a certain leaf, which is something we
   only needed in one place (update_current). If multi-children
   nodes are involved, this will require doing a walk in the other
   direction (from leaf to root). It does not affect the common
   case of single-child nodes.
 * The root/leaf pointers are now seen as a pair. One leaf generator
   can point to the current root. If a different leaf generator is
   used, we'll move the root pointer over to that one. Again, this
   is a cache to make the common linear chain case fast, trees may
   need to scan up the parent link.

Closes GH-6344.
