I've updated summary and description.

Functional is pretty same, but:
  - make it run with a single argument '67108864' by moving @summary tag
strait down to line after the @run tag
  - '-Xmx385' ->'-Xms385' in run command. MaxHeapSize will adjust a
accordingly.
  - spaces and code style.

Of course this issue may be closed as dup of JDK-8073354 and test will
pass after applying JDK-8073354. But I just want to use this RFE ID to
make test run with a single argument ( as you noticed previously ).

So this is all just cleanup - which is fine in itself but seems to have no bearing on the issue reported/described in the bug report. If you want to use this bug ID then I think you need to change the bug report substantially else it will just be confusing.

Thanks,
David

After Jespers comments I removed catch of OOME and added minimum heap

Please review: http://cr.openjdk.java.net/~lpriima/8073354/webrev.01/

Didn't see this before sending my previous reply.

I'm confused now. What functional change is now being made here ??

Thanks,

There is also a problem, if the memory on host is highly fragmented,
then we can't allocate continuous amount of heap for creating such big
array. I've added catch for OOME and treat this case as skip-pass to
make test more robust. Also I've removed explicit -Xmx385 from @run
tag and made it start with a single argument.

Is this expected behavior of this annotation ?

Yes that is the way jtreg defines tags:

http://openjdk.java.net/jtreg/tag-spec.html

"The argument tokens of a tag extend from the first token after the
tag token to the end of the comment, the end of the file, or the next
tag token, whichever comes first."

So everything between @run and @summary are taken to be the @run
commands. And there's no @comment tag unfortunately.

I will if Roger doesn't get to it first. It'll be 11 hours before
I can
push it.

This has been pushed but note there is a minor issue with the test. The jtreg tag specification doesn't terminate tags on newlines, they
continue until the next tag is encountered or the end of the
comment.
Consequently this:

 * @run main/othervm -Xmx385m TimSortStackSize2 67108864
 * not for regular execution on all platforms:
 * run main/othervm -Xmx8g TimSortStackSize2 1073741824
 * run main/othervm -Xmx16g TimSortStackSize2 2147483644

is processed as:

@run main/othervm -Xmx385m TimSortStackSize2 67108864 not for
regular
execution on all platforms: run main/othervm -Xmx8g
TimSortStackSize2
1073741824 run main/othervm -Xmx16g TimSortStackSize2 2147483644

and so TimSortStackSize2 is invoked with 18 arguments.

I hadn't realized 8072909 had been pushed without final reviewer
comments being addressed. :(

These changes seem okay. I hope they get promoted at the same
time as
the original changeset so we don't get test failures.

Hi Lev,

Christos,

Test may fail on shorter arrays(page 8 of paper). For
instance, on
worst
case, generated by test, it starts to fail on length 67108864. After increasing stack size of runs to merge, Arrays.sort(T[])
works
also on maximum possible array for HotSpot JVM.

I'd also like to see this documented somewhere in the code.
Presently
there is a reference to listsort.txt but then you have to go
and
find
it on the web. :( At a minimum could we please add:

 175          * computation below must be changed if
MIN_MERGE is
decreased.  See
 176          * the MIN_MERGE declaration above for more
information.
+             * The maximum value of 49 allows for an array
up to
length
+             * Integer.MAX_VALUE-4.

Roger, David,
I've updated the test (
http://cr.openjdk.java.net/~lpriima/8072909/webrev.01/test/java/util/Arrays/TimSortStackSize2.java.html






) to make it more suitable for regular execution:

   27  * @run main/othervm TimSortStackSize2 67108864

This will still fail on small memory devices:

:~> java TimSortStackSize2 67108864
Exception in thread "main" java.lang.OutOfMemoryError: Java
heap
space

as the default heap ergonomics may not be large enough. I
had to
add a
minimum heap of -Xmx385M to get it to run.

Thanks,
David

   28  * not for regular execution on all platforms:
29 * run main/othervm -Xmx8g TimSortStackSize2 1073741824 30 * run main/othervm -Xmx32g TimSortStackSize2 2147483644

Could you please push this:

?

For posterity can someone document this, and also the
value for
which
Integer.MAX_VALUE-4 fails?
