f59de7ea36 Export zend_pass_function to allow comparisons against it 2016-04-30 20:46:52 +02:00

6499162ff0 - get rid of EG(scope). zend_get_executed_scope() should be used instead. 
- ichanged zval_update_constant_ex(). Use IS_TYPE_IMMUTABLE flag on shared constants and AST, instead of "inline_change" parameter.

a186ac0e47 IS_CONST operands don't have to be separated. Use reference-counting instead of duplication. 
- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters

7abfaac901 Merge zend_execute_data->called_scope into zend_execute_data->This. 
"called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this.
Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL).
Some code might need to be adopted to support this change.
Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

3affc0e8a2 Fixed bug #68583 Crash in timeout thread 
This replaces the GUI element used for execution timeout handling
on Windows. Instead a timer queue technique is used, which is indeed
a thread pool. A timer queue timer is a lightweight object handled
but that thread pool and the timer thread spends most of the time
sleeping and waiting for an alert.

Please note also that this introduces neither binary nor source
breach. The custom timeout thread functions are deleted, however
they was not exported throug DLL, so couldn't be used by any
external code. As well they couldn't be used anywhere in the core
except in executor api, because those custom timeout thread
functions they used to operate on static variables which would
be overwritten (and that would blow).

So instead a relatively modern technique is used for the timeout
handling. It's still not perfect because the executor still has to
check EX(timed_out). This can be a topic for an improvement in
master. But brobably can be tricky as currently it seems to be not
possible to signal an individual thread. Also note another issue
that static variables aren't thread safe, but the current timer
implementation is.
