Austin Clements [Fri, 27 May 2016 16:21:14 +0000 (12:21 -0400)]
runtime: always call stackfree on the system stack

Currently when the garbage collector frees stacks of dead goroutines
in markrootFreeGStacks, it calls stackfree on a regular user stack.
This is a problem, since stackfree manipulates the stack cache in the
per-P mcache, so if it grows the stack or gets preempted in the middle
of manipulating the stack cache (which are both possible since it's on
a user stack), it can easily corrupt the stack cache.

Fix this by calling markrootFreeGStacks on the system stack, so that
all calls to stackfree happen on the system stack. To prevent this bug
in the future, mark stack functions that manipulate the mcache as
go:systemstack.

8 years agocrypto/tls: adjust dynamic record sizes to grow arithmetically
Russ Cox [Fri, 27 May 2016 13:50:06 +0000 (09:50 -0400)]
crypto/tls: adjust dynamic record sizes to grow arithmetically

The current code, introduced after Go 1.6 to improve latency on
low-bandwidth connections, sends 1 kB packets until 1 MB has been sent,
and then sends 16 kB packets (the maximum record size).

Unfortunately this decreases throughput for 1-16 MB responses by 20% or so.

Following discussion on #15713, change cutoff to 128 kB sent
and also grow the size allowed for successive packets:
1 kB, 2 kB, 3 kB, ..., 15 kB, 16 kB.
This fixes the throughput problems: the overhead is now closer to 2%.

I hope this still helps with latency but I don't have a great way to test it.
At the least, it's not worse than Go 1.6.

Comparing MaxPacket vs DynamicPacket benchmarks:

name              maxpkt time/op  dyn. time/op delta
Throughput/1MB-8    5.07ms ± 7%   5.21ms ± 7%  +2.73%  (p=0.023 n=16+16)
Throughput/2MB-8   15.7ms ±201%    8.4ms ± 5%    ~     (p=0.604 n=20+16)
Throughput/4MB-8    14.3ms ± 1%   14.5ms ± 1%  +1.53%  (p=0.000 n=16+16)
Throughput/8MB-8    26.6ms ± 1%   26.8ms ± 1%  +0.47%  (p=0.003 n=19+18)
Throughput/16MB-8   51.0ms ± 1%   51.3ms ± 1%  +0.47%  (p=0.000 n=20+20)
Throughput/32MB-8    100ms ± 1%    100ms ± 1%  +0.24%  (p=0.033 n=20+20)
Throughput/64MB-8    197ms ± 0%    198ms ± 0%  +0.56%   (p=0.000 n=18+7)

The small MB runs are bimodal in both cases, probably GC pauses.
But there's clearly no general slowdown anymore.

8 years agocmd/compile: fix liveness computation for heap-escaped parameters
Russ Cox [Wed, 25 May 2016 05:33:24 +0000 (01:33 -0400)]
cmd/compile: fix liveness computation for heap-escaped parameters

The liveness computation of parameters generally was never
correct, but forcing all parameters to be live throughout the
function covered up that problem. The new SSA back end is
too clever: even though it currently keeps the parameter values live
throughout the function, it may find optimizations that mean
the current values are not written back to the original parameter
stack slots immediately or ever (for example if a parameter is set
to nil, SSA constant propagation may replace all later uses of the
parameter with a constant nil, eliminating the need to write the nil
value back to the stack slot), so the liveness code must now
track the actual operations on the stack slots, exposing these
problems.

One small problem in the handling of arguments is that nodarg
can return ONAME PPARAM nodes with adjusted offsets, so that
there are actually multiple *Node pointers for the same parameter
in the instruction stream. This might be possible to correct, but
not in this CL. For now, we fix this by using n.Orig instead of n
when considering PPARAM and PPARAMOUT nodes.

The major problem in the handling of arguments is general
confusion in the liveness code about the meaning of PPARAM|PHEAP
and PPARAMOUT|PHEAP nodes, especially as contrasted with PAUTO|PHEAP.
The difference between these two is that when a local variable "moves"
to the heap, it's really just allocated there to start with; in contrast,
when an argument moves to the heap, the actual data has to be copied
there from the stack at the beginning of the function, and when a
result "moves" to the heap the value in the heap has to be copied
back to the stack when the function returns
This general confusion is also present in the SSA back end.

The PHEAP bit worked decently when I first introduced it 7 years ago (!)
in 391425ae. The back end did nothing sophisticated, and in particular
there was no analysis at all: no escape analysis, no liveness analysis,
and certainly no SSA back end. But the complications caused in the
various downstream consumers suggest that this should be a detail
kept mainly in the front end.

This CL therefore eliminates both the PHEAP bit and even the idea of
"heap variables" from the back ends.

First, it replaces the PPARAM|PHEAP, PPARAMOUT|PHEAP, and PAUTO|PHEAP
variable classes with the single PAUTOHEAP, a pseudo-class indicating
a variable maintained on the heap and available by indirecting a
local variable kept on the stack (a plain PAUTO).

Second, walkexpr replaces all references to PAUTOHEAP variables
with indirections of the corresponding PAUTO variable.
The back ends and the liveness code now just see plain indirected
variables. This may actually produce better code, but the real goal
here is to eliminate these little-used and somewhat suspect code
paths in the back end analyses.

The OPARAM node type goes away too.

A followup CL will do the same to PPARAMREF. I'm not sure that
the back ends (SSA in particular) are handling those right either,
and with the framework established in this CL that change is trivial
and the result clearly more correct.

Fixes #15747.

Acquire and release the TSAN synchronization point when calling malloc,
just as we do when calling any other C function. If we don't do this,
TSAN will report false positive errors about races calling malloc and
free.

We used to have a special code path for malloc and free, going through
the runtime functions cmalloc and cfree. The special code path for cfree
was no longer used even before this CL. This CL stops using the special
code path for malloc, because there is no place along that path where we
could conditionally insert the TSAN synchronization. This CL removes
the support for the special code path for both functions.

Instead, cgo now automatically generates the malloc function as though
it were referenced as C.malloc.  We need to automatically generate it
even if C.malloc is not called, even if malloc and size_t are not
declared, to support cgo-provided functions like C.CString.

Currently scanstack obtains its own gcWork from the P for the duration
of the stack scan and then, if called during mark termination,
disposes the gcWork.

However, this means that the number of workbufs allocated will be at
least the number of stacks scanned during mark termination, which may
be very high (especially during a STW GC). This happens because, in
steady state, each scanstack will obtain a fresh workbuf (either from
the empty list or by allocating it), fill it with the scan results,
and then dispose it to the full list. Nothing is consuming from the
full list during this (and hence nothing is recycling them to the
empty list), so the length of the full list by the time mark
termination starts draining it is at least the number of stacks
scanned.

Fix this by pushing the gcWork acquisition up the stack to either the
gcDrain that calls markroot that calls scanstack (which batches across
many stack scans and is the path taken during STW GC) or to newstack
(which is still a single scanstack call, but this is roughly bounded
by the number of Ps).

This fix reduces the workbuf allocation for the test program from
issue #15319 from 213 MB (roughly 2KB * 1e5 goroutines) to 10 MB.

Fixes #15319.

Note that there's potentially a similar issue in write barriers during
mark 2. Fixing that will be more difficult since there's no broader
non-preemptible context, but it should also be less of a problem since
the full list is being drained during mark 2.

Some overall improvements in the go1 benchmarks, plus the usual noise.
No significant change in the garbage benchmark (time/op or GC memory).

8 years agoruntime: update SP when jumping stacks in traceback
Austin Clements [Fri, 20 May 2016 18:57:55 +0000 (14:57 -0400)]
runtime: update SP when jumping stacks in traceback

When gentraceback starts on a system stack in sigprof, it is
configured to jump to the user stack when it reaches the end of the
system stack. Currently this updates the current frame's FP, but not
its SP. This is okay on non-LR machines (x86) because frame.sp is only
used to find defers, which the bottom-most frame of the user stack
will never have.

However, on LR machines, we use frame.sp to find the saved LR. We then
use to resolve the function of the next frame, which is used to
resolved the size of the next frame. Since we're not updating frame.sp
on a stack jump, we read the saved LR from the system stack instead of
the user stack and wind up resolving the wrong function and hence the
wrong frame size for the next frame.

This has had remarkably few ill effects (though the resulting profiles
must be wrong). We noticed it because of a bad interaction with stack
barriers. Specifically, once we get the next frame size wrong, we also
get the location of its LR wrong. If we happen to get a stack slot
that contains a stale stack barrier LR (for a stack barrier we already
hit) and hasn't been overwritten with something else as we re-grew the
stack, gentraceback will fail with a "found next stack barrier at ..."
error, pointing at the slot that it thinks is an LR, but isn't.

Fixes #15138.

Updates #15313 (might fix it).
