The code did not check whether the zend_hash_index_find calls succeded,
so PHP crashed when an array callback was called that contains two elements
which don't have the indices 0 and 1.
set_error_handler(null) and set_exception_handler(null) now return the
previous error/exception handler instead of just returning bool(true).
This is consistent with the behavior of these functions with non-null
values.
This allows the error handler to be reset using set_error_handler(null).
As the code suggests this behavior was already previously intended, but
the callback check was done too strictly.
This reverts the following two commits:
* 6ba2e662e4
* d8f8e98d8e
Laruence already did some partial changes to set_error_handler and
set_exception_handler. I'm reverting those modifications to apply the full
set of changes. (The modifications changed the code structure in a way that
would lead to more duplication with the new behavior.)
EG(arg_types_stack) is now also backed up when generators are used. This
allows the use of yield in nested method calls.
This commit adds two new functions to the zend_ptr_stack API:
zend_ptr_stack_push_from_memory
zend_ptr_stack_pop_into_memory
both taking the following arguments:
zend_ptr_stack *stack, int count, void **pointers
The native client compiler defines the C macro __x86_64__, but the size
of an unsigned int is only 4 bytes. This causes the compile to fail
because the inline asm code compiled is for an 8 byte unsigned int. Add
the correct defines to fix this.
As detailed in:
http://code.google.com/p/nativeclient/issues/detail?id=2255
Generators follow a different cleanup path, so the extra check for freeing
the execute_data is unnecessary there. It actually caused problems because
op_array->fn_flags could be in freed memory at that time (in case op_array
came from a closure in an ArrayAccess container).
This fixes the valgrind warning in Zend/tests/bug54367.phpt.
* PHP-5.4:
- fix build, there was no tsrm context there, doing a fetch but this is horribly slow, this fix needs improvement (or simply add a TSRM context in the signature in master
* generators: (70 commits)
Fix typos
Fix segfault when traversing a by-ref generator twice
Make sure that exception is thrown on rewind() after closing too
Remove implementation stubs for yield delegation
Fix several issues and allow rewind only at/before first yield
Run finally if generator is closed before finishing
Finally with return now works in generators too
Add dedicated opcode for returns from a generator
Disallow serialization and unserialization
Fix zts build (typo)
Drop Generator::close() method
Forgot to add test
Support trivial finally in generators (no yield, no return)
Fix implementation of Iterator interface
Add T_YIELD in tokenizer_data.c
Throw error also for return occuring before yield
Fix throwing of exceptions within a generator
Remove reference restrictions from foreach
Require parenthesis around yield expressions
Add some more tests
...
If you try to traverse an already closed generator an exception will now be
thrown.
Furthermore this changes the error for traversing a by-val generator by-ref
from an E_ERROR to an Exception.
