1. Increased the time for the sapi/cli/tests/php_cli_server.inc to accept connections.
2. sapi/cli/tests/php_cli_server.inc has errors messages and a `stop` function.
3. bug67429.phpt uses the `stop` function to shutdown the webserver before starting a new one.
4. Removed ext/curl/tests/bug48203_multi-win32.phpt test now that ext/curl/tests/bug48203_multi.phpt
runs on Windows also.
1. Increases the amount of time for the PHP built-in server to accept a connection
2. Outputs an error if the PHP built-in server fails
3. In bug48203_multi.phpt the test no longer starts and stops multiple PHP built-in servers
The required field, until now, stored how many required parameters
the function, it belongs to, has. I think this is rather problematic
because it's a feature of the function to know how many required
parameters it has, not of the parameter itself. The parameter should
only say if it's required or optional (among other unrelated things).
Also storing the function's number of required parameters in every
parameter was redundant since the _zend_function structure already
has that information. And storing the same value (number of required
parameters) across multiple variables is inefficient and could lead
to inconsistencies.
The zend_vm_gen.php generator now checks if the condition is already
enclosed by parentheses, and them only if needed.
This fixes nine clang/llvm parentheses-equality warnings.
Primarily related to the path handling datatypes, to avoid unnecessary
casts, where possible. Also some rework to avoid code dup. Probably
more places are to go, even not path related, primarily to have less
casts and unsigned integers where possible. That way, we've not only
less warnings and casts, but are also safer with regard to the
integer overflows. OFC it's not a panacea, but still significantly
reduces the vulnerability potential.
These conditions were formerly `!q->pData` and `!p->pData`, and should
now be detected as undefined variables, using the special type IS_UNDEF.
Incidentally, this syntax raised a logical-not-parentheses compiler
warning, now gone.
