30156d588c Fixed bug #63217 
Don't automatically convert literal string keys to integers on
array access, as we may be dealing with an ArrayAccess object,
rather than a plain array.

7f67513ca3 Lazy function copying from op_cache SHM into process memory 2018-06-25 19:53:58 +03:00
Nikita Popov
61d00a6cf3
Use COPY_DEREF instead of COPY_UNREF 
This fixes the behavior when the storage location of the fetch is
modified before the operand is dereferenced by the using VM opcode.

Furthermore it elimiates references as a possible return value from
*_R opcodes, which will give us more opportunities for inferences,
in particular in regard to typed properties.

95a0709935 Fix handling of ERROR zval in op1 of ASSIGN_REF 
If op1 is ERROR the behavior is to not perform any assignment and
return NULL. However, if the RHS was a by-value returning function,
we'd instead emit a notice and return the RHS as the return value
(even though the value was not assigned to anything -- the temporary
is immediately destroyed).

This normalized the behavior to always check for an ERROR in op1
first.

d877d18676 Error on by-ref assign to overloaded prop returning ref 
This error was already thrown if __get() was used -- however not
if it returned by reference. This is incorrect, because the
reference return makes no difference to a by-reference assignment,
which has reference-breaking semantics. The result was that the
assignment was accepted silently, even though it didn't do anything
(not even the value was assigned, let alone the reference).

b0af9ac733 Avoid live range references in opcodes 
Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.

fd30c59e04 Fixed bug #75786 
SEND_UNPACK on iterators was duplicating references in-place,
which effectively leaks the original value and causes an off-by-one
refcount on the duplicated value.

Replace this with a deref, as an actual duplication is not even
needed in this case.

da781a5ac2 Allow internal functions to return values by reference (this was disabled in implementation of DO_ICALL, but enabled in DO_FCALL). 
However, don't require internal functions returning by reference to return a reference.
Mark unserialize() as returning by reference and remove unwrap_reference hack, to allow proper returning of self referenced arrays using a reference.
Currently unserialize() is the only internal function that may return a reference.

c698299550 Interned strings unification for TS/NTS 
Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings

- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end

There is no runtime interning.

With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
