These strings are returned to userland by password_algos(),
which violates thread-safety invariants. Create persistent
interned strings for them instead.
Some extensions try to use the date features in their own shutdown,
most notably some logging functions. Because of that, move the
cache tear down until after these resources have been cleaned up.
Adding two `zend_long`s may overflow, and casting `size_t` to
`zend_long` may truncate; we can avoid this here by enforcing unsigned
arithmetic.
Closes GH-7240.
This ports 247105ae1a to the JIT
implementation. The issue doesn't trigger on the original test
case with JIT, but I ran into a case that does trigger with JIT
once we have typed properties.
For a particular assignment, a non-coerced constant assignment
value will remain valid. However, opcache merges cache slots for
all identical property references, which means that this
optimization also disables property type checks for all other
operands on the property that occur in the same functions.
This could be addressed by blocking cache slot merging in opcache,
but I prefer dropping it entirely instead. It does not seem
important enough to warrant doing that.
Encoding a negative zero as `-0` is likely to loose the sign when
decoding (at least it does with `json_decode()`). Therefore, we encode
it as if `JSON_PRESERVE_ZERO_FRACTION` was specified, i.e. as `-0.0`.
Closes GH-7234.
Trimming a potentially over-allocated string appears to be reasonable,
so we drop the condition altogether.
We also re-allocate twice the size needed in the first place, and not
roughly tripple the size.
Closes GH-7231.
Updating based on the properties info HT will miss private parent
properties that have been shadowed in the child class. Instead,
perform updating directly on the default properties table.
We can't do the same for static properties, because those don't
have a convenient way to look up the property type from the
property offset. However, I don't believe the problem exists for
static properties, because we're always going to be using the
property on the class it was declared on, while children only hold
INDIRECT references. As such, this should be covered by parent
class const updating.
Fixes oss-fuzz #35906.
We can't destroy the result operand early, because the division
might fail, in which case we need to preserve the original value.
Place the division result in a temporary zval, and only copy it
on success.
Fixes oss-fuzz #35876.
