The file extension to mime type mapping *must* not depend on the file
extension's case for case-insensitive file systems, and *should* not
for case-sensitive file systems.
Don't expose references in debug_backtrace() or exception traces.
This is regardless of whether the argument is by-reference or not.
As a side-effect of this change, exception traces may now acquire
the interior value of a reference, which may be unexpected for
some internal functions. This is what necessitated the change in
the spl_array sort implementation.
When an input variable name contains a non matched open bracket, we not
only have to replace that with an underscore, but also all following
forbidden characters.
It does not make sense to make assumptions about `PHP_CONFIG_FILE_PATH`
during build time, since that value is never used during run time on
Windows. Since there is no `--with-config-file-path` on Windows
either, we define `PHP_CONFIG_FILE_PATH` as `""`.
We must not mix multibyte and wide character strings in the
`COAUTHIDENTITY` structure. Using wide character strings throughout
would have the advantage that the remote connection can be established
regardless of the code page of the server, but that would more likely
break BC, so we just drop the wide character string conversion of the
username.
In line with usual rules, give untyped properties a null default
value. Otherwise constructor promotion would give you a property
declaration that cannot be achieved through any other means.
Similar to what is done for ReflectionType itself, copy the
type name stored inside ReflectionProperty. Also make sure the
type field is always initialized for dynamic properties.
This is a non-issue in PHP 8, because we store a pointer to the
property_info there, rather than a copy.
When performing an RW modification of an array offset, the undefined
offset warning may call an error handler / OB callback, which may
destroy the array we're supposed to change. Detect this by temporarily
incrementing the reference count. If we find that the array has been
modified/destroyed in the meantime, we do nothing -- the execution
model here would be that the modification has happened on the destroyed
version of the array.
I haven't tracked down in detail where the interaction with
increment_function comes from, but the root problem here is failure
to handle the illegal offset type exception.
In the interest of avoiding side-effects during dumping, I'm
replacing the value with a <constant ast> string instead of
performing an update constant operation.
