* siri/sasl/release_handler-windows/OTP-9306:
Make release_handler work with windows services
|
|
This commit adds test cases from release_handler_SUITE on windows,
including some corrections in erlsrv and release_handler.
|
|
All uses of the old deprecated atomic API in the runtime system
have been replaced with the use of the new atomic API. In a lot of
places this change imply a relaxation of memory barriers used.
|
|
The ethread atomics API now also provide double word size atomics.
Double word size atomics are implemented using native atomic
instructions on x86 (when the cmpxchg8b instruction is available)
and on x86_64 (when the cmpxchg16b instruction is available). On
other hardware where 32-bit atomics or word size atomics are
available, an optimized fallback is used; otherwise, a spinlock,
or a mutex based fallback is used.
The ethread library now performs runtime tests for presence of
hardware features, such as for example SSE2 instructions, instead
of requiring this to be determined at compile time.
There are now functions implementing each atomic operation with the
following implied memory barrier semantics: none, read, write,
acquire, release, and full. Some of the operation-barrier
combinations aren't especially useful. But instead of filtering
useful ones out, and potentially miss a useful one, we implement
them all.
A much smaller set of functionality for native atomics are required
to be implemented than before. More or less only cmpxchg and a
membar macro are required to be implemented for each atomic size.
Other functions will automatically be constructed from these. It is,
of course, often wise to implement more that this if possible from a
performance perspective.

The efile driver will now use chunked data on list_dir. This will
lessen the number of sends to prim_file and hence improve
performance. This method is utilized in both direct and async cases.
|
|
|
|
|
|
An experimental version of Dialyzer discovered that the atom that
replaced the DRV macro in prim_file ends up in calls to
erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The
documentation states that this call requires a string there.
This change is also consistent with the one introduced in commit
0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.

If an IPv4 fd is opened as an IPv6 socket, unexpected behaviour can
occur. For example, if an IPv4 UDP socket is opened and passed into
Erlang as an IPv6 socket, the first 3 bytes (corresponding to 1 byte
representing the protocol family, 2 bytes set to the port) are stripped
from the payload. The cause of the UDP payload truncation happens in
inet_drv.c:packet_inet_input when a call to inet_get_address fails
silently because the family is set to PF_INET6 but the buffer len is
the size of an IPv4 struct sockaddr_in.
Prevent this behaviour by checking that the protocol family of the file
descriptor matches the family of the requested Erlang socket.
{ok, S1} = gen_udp:open(0, [binary, inet]),
{ok, FD} = inet:getfd(S1),
{ok, Port} = inet:port(S1),
{ok, S} = gen_udp:open(Port, [binary, {fd, FD}, inet6]),
{ok, C} = gen_udp:open(0, [binary]),
Msg = <<1,2,3,4,5>>,
gen_udp:send(C, "127.0.0.1", Port, Msg),
receive
{udp, S, _, _, Msg} -> ok;
{udp, S, _, _, NewMsg} -> {error, Msg, NewMsg}
end.
This test results in: {error,<<1,2,3,4,5>>,<<4,5>>}
Thanks to Andrew Tunnell-Jones for finding the bug and the test case!

F_HIBERNATE_SCHED flag that was introduced in b7ecdcd1ae9e11b8f75e must
be cleared in hipe_mode_switch as well. Otherwise, processes running
HiPE code that hibernate, wake up and then trap into a BIF will not be
rescheduled.

Add needed barriers for write_concurrency tables
Homogenize memory barriers on atomics
|
|
|
|
|
|
Counters for active, and used schedulers have been coalesced in
order to reduce the amount of atomic operations needed.
Some currently not strictly necessary barriers have also been added
in order to be future proof.

|
|
Make sure that we don't have to wait in poll before break
handling is done.
|
|
This is not a bugfix. The change is done in order to avoid a
future bug.

Ets tables using ordered_set could potentially get into an
internally inconsistent state.
