8 years agonet: implement asynchonous cancelable I/O on Plan 9
David du Colombier [Fri, 11 Nov 2016 19:49:11 +0000 (20:49 +0100)]
net: implement asynchonous cancelable I/O on Plan 9

This change is an experimental implementation of asynchronous
cancelable I/O operations on Plan 9, which are required to
implement deadlines.

There are no asynchronous syscalls on Plan 9. I/O operations
are performed with blocking pread and pwrite syscalls.

Implementing deadlines in Go requires a way to interrupt
I/O operations.

It is possible to interrupt reads and writes on a TCP connection
by forcing the closure of the TCP connection. This approach
has been used successfully in CL 31390.

However, we can't implement deadlines with this method, since
we require to be able to reuse the connection after the timeout.

On Plan 9, I/O operations are interrupted when the process
receives a note. We can rely on this behavior to implement
a more generic approach.

When doing an I/O operation (read or write), we start the I/O in
its own process, then wait for the result asynchronously. The
process is able to handle the "hangup" note. When receiving the
"hangup" note, the currently running I/O operation is canceled
and the process returns.

This way, deadlines can be implemented by sending an "hangup"
note to the process running the blocking I/O operation, after
the expiration of a timer.

Fixes #11932.

runtime: fix Windows profiling crash

I don't have any way to test or reproduce this problem,
but the current code is clearly wrong for Windows.
Make it better.

As I said on #17165:

But the borrowing of M's and the profiling of M's by the CPU profiler
seem not synchronized enough. This code implements the CPU profiler
on Windows:

func profileloop1(param uintptr) uint32 {
stdcall2(_SetThreadPriority, currentThread, _THREAD_PRIORITY_HIGHEST)

for {
stdcall2(_WaitForSingleObject, profiletimer, _INFINITE)
first := (*m)(atomic.Loadp(unsafe.Pointer(&allm)))
for mp := first; mp != nil; mp = mp.alllink {
thread := atomic.Loaduintptr(&mp.thread)
// Do not profile threads blocked on Notes,
// this includes idle worker threads,
// idle timer thread, idle heap scavenger, etc.
if thread == 0 || mp.profilehz == 0 || mp.blocked {
continue
}
stdcall1(_SuspendThread, thread)
if mp.profilehz != 0 && !mp.blocked {
profilem(mp)
}
stdcall1(_ResumeThread, thread)
}
}
}

func profilem(mp *m) {
var r *context
rbuf := make([]byte, unsafe.Sizeof(*r)+15)

tls := &mp.tls[0]
gp := *((**g)(unsafe.Pointer(tls)))

// align Context to 16 bytes
r = (*context)(unsafe.Pointer((uintptr(unsafe.Pointer(&rbuf[15]))) &^ 15))
r.contextflags = _CONTEXT_CONTROL
stdcall2(_GetThreadContext, mp.thread, uintptr(unsafe.Pointer(r)))
sigprof(r.ip(), r.sp(), 0, gp, mp)
}

func sigprof(pc, sp, lr uintptr, gp *g, mp *m) {
if prof.hz == 0 {
return
}

// Profiling runs concurrently with GC, so it must not allocate.
mp.mallocing++

... lots of code ...

mp.mallocing--
}

A borrowed M may migrate between threads. Between the
atomic.Loaduintptr(&mp.thread) and the SuspendThread, mp may have
moved to a new thread, so that it's in active use. In particular
it might be calling malloc, as in the crash stack trace. If so, the
mp.mallocing++ in sigprof would provoke the crash.

Those lines are trying to guard against allocation during sigprof.
But on Windows, mp is the thread being traced, not the current
thread. Those lines should really be using getg().m.mallocing, which
is the same on Unix but not on Windows. With that change, it's
possible the race on the actual thread is not a problem: the traceback
would get confused and eventually return an error, but that's fine.
The code expects that possibility.

Fixes #17165.

text/template: reintroduce implicit indirect of interface values in builtin funcs

CL 31462 made it possible to operate directly on reflect.Values
instead of always forcing a round trip to interface{} and back.
The round trip was losing addressability, which hurt users.

The round trip was also losing "interface-ness", which helped users.
That is, using reflect.ValueOf(v.Interface()) instead of v was doing
an implicit indirect any time v was itself an interface{} value: the result
was the reflect.Value for the underlying concrete value contained in the
interface, not the interface itself.

CL 31462 eliminated some "unnecessary" reflect.Value round trips
in order to preserve addressability, but in doing so it lost this implicit
indirection. This CL adds the indirection back.

It may help to compare the changes in this CL against funcs.go from CL 31462:
https://go-review.googlesource.com/#/c/31462/4/src/text/template/funcs.go

net: apply tcp4/tcp6 restrictions to literals in ResolveTCPAddr

The restrictions were already being applied to the IP addresses
received from the host resolver. Apply the same restrictions to
literal IP addresses not passed to the host resolver.

For example, ResolveTCPAddr("tcp4", "[2001:db8::1]:http") used
to succeed and now does not (that's not an IPv4 address).

Perhaps a bit surprisingly,
ResolveTCPAddr("tcp4", "[::ffff:127.0.0.1]:http") succeeds,
behaving identically to ResolveTCPAddr("tcp4", "127.0.0.1:http"), and
ResolveTCPAddr("tcp6", "[::ffff:127.0.0.1]:http") fails,
behaving identically to ResolveTCPAddr("tcp6", "127.0.0.1:http").
Even so, it seems right to match (by reusing) the existing filtering
as applied to addresses resolved by the host C library.
If anyone can make a strong argument for changing the filtering
of IPv4-inside-IPv6 addresses, the fix can be applied to all
the code paths in a separate CL.

Fixes #14037.

Interestingly, this only became a problem when CL 32850 marked
TestImportMain as parallel.  Before that, "x" was overwritten and remove
in a later test, TestGoBuildOutput.  The latter test is not marked as
parallel, so now it is run first.  It is rather fragile for two tests to
compete over the same filename, but this change is correct regardless.
