re2c version 4 enabled some warnings by default. This fixes re2c code
for the `-Wuseless-escape` warnings.
There are two same issues reported.
Issue: GH-17523
Closes: GH-17204
Both these issues have the same root cause, their reproducer is
extremely similar so I don't duplicate the test.
If the parser invokes the lexer, and the lexer fails, it could've
allocated a string which must be freed when the parser backs up.
The `%destructor` list is responsible for this but did not have an entry
for `fallback` yet. Solve the issue by adding such an entry.
Closes GH-19012.
The first warning may trigger an error handler, destroying the operand
and its string. So we need to protect the string in that case.
Care was taken to avoid unnecessary refcounts and to avoid touching the
hot code path.
Closes GH-18951.
When the array functions perform their operation in-place, the
`@refcount 1` annotation is wrong and causes a failure under
`ZEND_VERIFY_FUNC_INFO`.
The test file tests all functions that have the in-place optimization,
even those that didn't have the refcount annotation, just to prevent
future regressions.
Closes GH-18929.
This is necessary because the VM frees operands with the nogc variants. We
cannot just call gc_possible_root() because the object may no longer exist at
that point.
Fixes GH-18907
Closes GH-18917
real_size is returned by memory_get_usage(true), which previously returned 0.
Discovered in Symfony ConsumeMessagesCommandTest::testRunWithMemoryLimit()
through nightly.
Closes GH-18880

pdo_odbc: Fix memory leak if WideCharToMultiByte() fails
Fix memory leak on php_odbc_fetch_hash() failure
Do not delete main chunk in zend_gc
This API can't handle references, yet everyone keeps forgetting that it
can't and that you should DEREF upfront. Fix every type of this issue
once and for all by moving the reference handling to this Zend API.
Closes GH-18761.
The intent here was to assign the first found line. Instead this
always fell back to CG(zend_lineno).
Not sure if this line matters for anything in php-src, but the
issue was observed in https://github.com/nikic/php-ast/issues/247.
Add recursion protection when emitting deprecation warnings for class
constants, since the deprecation message can come from an attribute that is
using the same constant for the message, or otherwise result in recursion.
But, internal constants are persisted, and thus cannot have recursion
protection. Otherwise, if a user error handler triggers bailout before the
recursion flag is removed then a subsequent request (e.g. with `--repeat 2`)
would start with that flag already applied. Internal constants can presumably
be trusted not to use deprecation messages that come from recursive attributes.
Fixes GH-18463
Fixes GH-17711
The trait handling for property hooks in preloading did not exist, we
add a check to skip trait clones and we add the necessary code to update
the op arrays.
Closes GH-18586.
The VM assumes that an exception must be handled when the AST evaluation
returns FAILURE. However, the comparison functions always return SUCCESS
even if an exception happened. This can be fixed in
zend_ast_evaluate_inner() or we can make is_smaller_function() etc check
for the exception. I chose the former to avoid impact or API breaks.
Perhaps in the future the comparison functions should either return void
or return whether an exception happened, as to be not misleading.
Closes GH-18589.
This causes problems if an allocation profiler decides to walk the
stack, or if the engine itself OOMs on this opcode, and it tries to
print file and line information.
