[9.4 bug] The database server hangs with write-heavy workload on Windows

Hello,

One user reported a hang problem with 9.4 beta2 on Windows.  The PostgreSQL 
is 64-bit version.  I couldn't find the cause, but want to solve the 
problem.  Could you help with this?

I heard that the user had run 16 concurrent psql sessions which executes 
INSERT and UPDATE statements, which is a write-intensive stress test.  He 
encountered the hang phenomenon twice, one of which occured several hours 
after the start of the test, and the other occured about an hour after the 
test launch.

The user gave me the stack traces, which I attached at the end of this mail. 
The problem appears to be related to the xlog insert scaling.  But I can't 
figure out where the root cause lies --- WAL slot handling, spinlock on 
Windows, or PGSemaphoreLock/UnLock on Windows?

The place I suspect is S_UNLOCK().  It doesn't use any memory barrier.  Is 
this correct on Intel64 processors?

#define S_UNLOCK(lock)  (*((volatile slock_t *) (lock)) = 0)


The rest of this mail is the stack trace:

It'd be interesting and useful to run this test on a debug build of
PostgreSQL, i.e. one compiled against the debug version of the C library
and with full debuginfo not just minimal .pdb.

How were the stacks captured - what tool?

What precisely do you mean with "Intel64"? 64bit x86 or Itanium?

Also, what's the precise workload? Can you reproduce the problem?

Although I'm not sure the user can do this now, I'll ask him anyway.

According to his mail, Windbg or userdump.exe.  I'll ask him about this.

64-bit x86, i.e. x86-64.

IIUC, each client inserts 1000 records into one table, then repeats updating 
all those records.  I'll ask him again.

It sounds like they've produced a test case, so they should be able to
with a bit of luck.

Or even better, send you the test case.

Thanks. The stack trace looks fairly sane, i.e. there's nothing
obviously out of whack at a glance, but I tend to get more informative
traces from Visual Studio debugging sessions.

Your next step here really needs to be to make this reproducible against
a debug build. Then see if reverting the xlog scalability work actually
changes the behaviour, given that you hypothesised that it could be
involved.

As I said off-list, if you can narrow the test case down to something
that can be reproduced more quickly, you could also git-bisect to seek
the commit at fault. Even if the test case takes an hour, that's still
viable:

$ git bisect start
$ git bisect bad
$ git bisect good REL9_3_RC1
Bisecting: a merge base must be tested
[e472b921406407794bab911c64655b8b82375196] Avoid deadlocks during
insertion into SP-GiST indexes.
$ git bisect good
Bisecting: 1026 revisions left to test after this (roughly 10 steps)
...

Thanks to the magic of binary search.

I asked the user about this.  It sounds like the relevant test case consists 
of many scripts.  He explained to me that the simplified test steps are:

1. initdb
2. pg_ctl start
3. Create 16 tables.  Each of those tables consist of around 10 columns.
4. Insert 1000 rows into each of those 16 tables.
5. Launch 16 psql sessions concurrently.  Each session updates all 1000 rows 
of one table, e.g., session 1 updates table 1, session 2 updates table 2, 
and so on.
6. Repeat step 5 50 times.

This sounds a bit complicated, but I understood that the core part is 16 
concurrent updates, which should lead to contention on xlog insert slots 
and/or spinlocks.

Thank you, but that may be labor-intensive and time-consuming.  In addition, 
the user uses a machine with multiple CPU cores, while I only have a desktop 
PC with two CPU cores.  So I doubt I can reproduce the problem on my PC.

I asked the user to change S_UNLOCK to something like the following and run 
the test during this weekend (the next Monday is a national holiday in 
Japan).

#define S_UNLOCK(lock)  InterlockedExchange(lock, 0)

FYI, the user reported today that the problem didn't occur when he ran the 
same test for 24 hours on 9.3.5.  Do you see something relevant in 9.4?

Hm. I've run similar loads on linux for long enough that I'm relatively
sure I'd have seen this.

Could you get them to print out the content's of the lwlock all these
processes are waiting for?

I don't think you can trivially revert the xlog scalability stuff.

Well, it'll also be labor intensive for the community to debug.

That shouldn't be required. For one, on 9.4 (not 9.5!) spinlock releases
only need to prevent reordering on the CPU level. As x86 is a TSO
architecture (total store order) that doesn't require doing anything
special. And even if it'd require more, on msvc volatile reads/stores
act as acquire/release fences unless you monkey with the compiler settings.

I was able to reproduce this. I reduced wal_buffers to 64kB, and
NUM_XLOGINSERT_LOCKS to 4 to increase the probability of the deadlock,
and ran a test case as above on my laptop for several hours, and it
finally hung. Will investigate...

Ok, I tracked the bug down to the way LWLockAcquireWithVar,
LWLockRelease, and LWLockWaitForVar work. Here's a simplified model of
how this happens:

Three backends are needed to cause the deadlock. Let's call them A, B
and C. There are two locks, and one of them protects a variable, i.e. is
used with LWLockAcquireWithVar et al. The backends run these operations:

A: (checkpointer does this in xlog.c)
LWLockAcquireWithVar(lock1, value1ptr, 0xFF)
LWLockAcquire(lock2);
LWLockRelease(lock1);
LWLockRelease(lock2);

B:
LWLockAcquire(lock2, LW_EXCLUSIVE)
LWLockWaitForVar(lock1, value1ptr, 0, &newval);
LWLockRelease(lock2);

C:
LWLockAcquireWithVar(lock1, value1ptr, 0);
LWLockRelease(lock1)

So, A acquire both locks, in order lock1, lock2. B acquires lock2, and
then waits for lock1 to become free or have a non-zero value in the
variable. So A and B operate on the locks in opposite order, but this is
not supposed to deadlock, because A sets the variable to non-zero, and B
waits for it to become non-zero. Then there is a third action, C, that
just acquire lock1, with zero value.

This is the sequence that leads to the deadlock:

(both locks are free in the beginning)
C: LWLockAcquireWithVar(lock1, 0). Gets the lock.
A: LWLockAcquireWithVar(lock1, 0xFF). Blocks.
B: LWLockAcuire(lock2). Gets the lock.
B: LWLockWaitForVar(lock 1, 0). Blocks.

C: LWLockRelease(lock1). Wakes up A and B. Sets releaseOK=false because
A is waiting for the lock in exclusive mode.
C: LWLockAcquireWithVar(lock1, 0). Steals the lock back before A or B
have had a chance to run.

B: Wakes up. Observes the lock is still taken, with val 0. Adds itself
back to wait queue and goes back to sleep.
C: Releases lock 1, releaseOK is false because A has not run yet. Does
not wake up anyone.
A: Wakes up. Acquires lock 1 with val 0xFF...
A: Blocks waiting on lock 2.

So the gist of the problem is that LWLockRelease doesn't wake up
LW_WAIT_UNTIL_FREE waiters, when releaseOK == false. It should, because
a LW_WAIT_UNTIL FREE waiter is now free to run if the variable has
changed in value, and it won't steal the lock from the other backend
that's waiting to get the lock in exclusive mode, anyway.

I noticed another potential bug: LWLockAcquireCommon doesn't use a
volatile pointer when it sets the value of the protected variable:

>     /* If there's a variable associated with this lock, initialize it */
>     if (valptr)
>         *valptr = val;
>
>     /* We are done updating shared state of the lock itself. */
>     SpinLockRelease(&lock->mutex);

If the compiler or CPU decides to reorder those two, so that the
variable is set after releasing the spinlock, things will break.

The attached patch should fix these two bugs. It is for REL9_4_STABLE;
needs to be forward-patched ot master too. This fixes the deadlock for
me. Anyone see any issues with this?

Thanks MauMau for the testing!

The volatile-ization portion of this should not be forward-ported to
master; in master, spinlock operations have compiler barrier
semantics, and we've accordingly started removing volatile qualifiers
from various parts of the code, including lwlock.c.

I'm not a big fan of that change. Right now we don't iterate the waiters
if releaseOK isn't set. Which is good for the normal lwlock code because
it avoids pointer indirections (of stuff likely residing on another
cpu). Wouldn't it be more sensible to reset releaseOK in *UpdateVar()? I
might just miss something here.

Good catch. As Robert says that should be fine with master, but 9.4
obviously needs it.

I can't get excited about that. It's pretty rare for releaseOK to be
false, and when it's true, you iterate the waiters anyway.

That's not enough. There's no LWLockUpdateVar involved in the example I
gave. And LWLockUpdateVar() already wakes up all LW_WAIT_UNTIL_FREE
waiters, regardless of releaseOK.

Hmm, we could set releaseOK in LWLockWaitForVar(), though, when it
(re-)queues the backend. That would be less invasive, for sure
(attached). I like this better.

BTW, attached is a little test program I wrote to reproduce this more
easily. It exercises the LWLock* calls directly. To run, make and
install, and do "CREATE EXTENSION lwlocktest". Then launch three
backends concurrently that run "select lwlocktest(1)", "select
lwlocktest(2)" and "select lwlocktest(3)". It will deadlock within seconds.

Thank you very much.  I didn't anticipate such a difficult complicated 
cause.  The user agreed to try the patch tonight.  I'll report back the 
result as soon as I got it from him.

BTW, in LWLockWaitForVar(), the first line of the following code fragment is 
not necessary, because lwWaitLink is set to head immediately.  I think it 
would be good to eliminate as much unnecessary code as possible from the 
spinlock section.
 proc->lwWaitLink = NULL;
 /* waiters are added to the front of the queue */ proc->lwWaitLink = lock->head;

The test ran successfully without hang for 24 hours.  It was run with your 
patch + the following:
