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.

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.
We need to extend the hash table before performing raw append
operations.
This doesn't matter if preloading happens in the same process,
as the tables will be large enough to hold all entries as a
side-effect of the preloading process. However, if preloading
happens in a different process, we need to reserve space here.
Due to ASLR restrictions, preloading on Windows does not work with
any code that has preloading dependencies on internal classes.
This effectively makes it unusable for any non-trivial codebase.
Instead of pretending like preloading is going to work, only to
make people realize that it really doesn't once they get beyond
a dummy example, we disable support for preloading on Windows
entirely.
Closes GH-4999.
Fix file cache serialization of property types. I'm changing the
overall type serialization format to perform additional adjustments
in order to yield a plausible pointer for zend_type, rather than
using an entirely separate serialization format, as was previously
done. That would have been annoying to extend to the case of CE
pointers.
