For x ? y : z style structures, the live range starts at z, but
may also hold the value of y. Make sure that the refcounting check
takes this into account, by checking the type of a potential phi
user.
If there is a previous use of the new variable in the phi, we need
to NULL out the use chain of the new source we're adding.
Test case is reduced from an assertion failure in the Symfony Demo.
This cherry-picks 33969c2252 and
2effbfd871 from PHP-8.0.
The issues these commits fix could also manifest in PHP 7.4, and
a commenter on bug #80307 reports this this might indeed be
happening.
We should use normal function renaming if the function is declared
during preloading itself, rather than afterwards.
This fixes a regression introduced by
68f80be9d1.
Add db2_execute() to the list of functions accessing the local
scope. Ideally the API wouldn't do that, but it seems most
pragmatic to address this on the opcache side at this point.
Modules may have changed after restart which can cause dangling pointers from custom opcode handlers in the second-level cache files. This fix includes the installed module names and versions in the accel_system_id hash as entropy. Closes GH-5836
We can't just remove the uses, we need to replace uses.
The test case only fails on master with SSA integrity violations,
but I believe the root issue also existed previously.
op_arrays can be shared on two levels: Either the op_array is
completely shared, or it is distinct but shares all members
(apart from static_variables).
The the op_array is distinct, we need to make sure to properly
initialize the MAP_PTR structures.
These systems has two versions of the iovec interface dependent on
compiler flags passed, the legacy version causing little build issue.
Closes GH-5939.
Instead of storing the mapping base address and the address of
`execute_ex()` in a separate file in the temporary folder, we store
them right at the beginning of the memory mapping.
This reverts commit e1f6ab3388, reversing
changes made to e0ebe56ebf.
There are obviously issues with running tests in parallel, maybe
related to the cache ID. This needs to be investigated. Revert for
now.
Instead of storing the mapping base address and the address of
`execute_ex()` in a separate file in the temporary folder, we store
them right at the beginning of the memory mapping.
If the class is already linked, we need to serialize and
unserialize INDIRECTed static properties. Normally these would
be set up when copying from cache.
