by ignoring literals.
erts_internal:check_process_code will be called again anyway
(with option {copy_literals, true}) before the module is actually purged.
No need to check literals twice.

* Same process must do enable-disable.
* System process will force it and never get 'aborted'

as it's not a public interface.

Problem: erlang:purge_module/1 is not safe in the sense
that very bad things may happen if the code to be purged
is still referred to by live processes.
Introduce erts_internal:purge_module which is the same as the old
erlang:purge_module BIF (except it returns false if no such old module).
Implement erlang:purge_module in Erlang and let it invoke
erts_code_purger for safe purging where all clogging processes
first are killed.

memset seen to fail with values larger than 255
on (armata) 32-bit ARM Debian
with EGLIBC 2.13-38+rpi2+deb7u8
and gcc 4.6.3-14+rpi1.
|
|
as is strongly recommended by gcc man page.
We use __attribute__ ((visibility("default"))) to make sure
the init functions are properly exported.
|
|
The comment is misleading and
no need to "export" static windows drivers.
DRIVER_INIT for dynamic windows drivers
is defined in erl_win_dyn_driver.h

The nature of aux work is such that dirty schedulers should not
attempt to perform it. Modify the code to ensure that dirty schedulers
avoid aux work.
Also fix an incorrect assumption about the size of a Uint in the
ErtsDirtySchedId type.

We always want the error to propagate up to the application
when a child cannot be created.
|
|
when called by hash.c for example.
We use ASSERT from sys.h but erl_child_setup implements
its own erl_assert_error() as it doesn't link with sys.o.
|
|
With the new forker implementation also enomem can be returned
as an indicator that it is not possible to create more ports.
