Hello,<br>
<br>
may I have a couple of reviews for a quite trivial fix, which splits
up the hotspot_gc jtreg group:<br>
<br>
<a class="moz-txt-link-freetext" href="http://cr.openjdk.java.net/~dfazunen/8152422/webrev.00/">http://cr.openjdk.java.net/~dfazunen/8152422/webrev.00/</a><br>
<a class="moz-txt-link-freetext" href="https://bugs.openjdk.java.net/browse/JDK-8152422">https://bugs.openjdk.java.net/browse/JDK-8152422</a><br>
<br>
The purpose of the split is to parallelize the execution of GC tests
in JPRT.<br>
Running the tests located under the gc/g1 folder takes approximately
the same amount of time as running other tests.<br>
<br>
To reduce the execution time (for ~20%) I propose to remove a couple
of slow tests from JPRT run:<br>
<br>
38,52 : gc/cms/TestMBeanCMS.java (former name
test/gc/6581734/Test6581734.java)<br>
CMS is updating vary rare now, so it's very unlikely to break the
area under this test <br>
<br>
18,05 :
gc/survivorAlignment/TestPromotionFromSurvivorToTenuredAfterMinorGC.java<br>
There will remain 3 very similar tests for survivor alignment<br>
5,38 :
gc/survivorAlignment/TestPromotionFromEdenToTenured.java<br>
6,47 : gc/survivorAlignment/TestAllocationInEden.java<br>
6,78 :
gc/survivorAlignment/TestPromotionFromSurvivorToTenuredAfterFullGC.java<br>
so dropping this test will not create a gap in testing.<br>
<br>
I also restored test which were excluded from JPRT execution a year
ago:<br>
90,66 : gc/g1/TestGreyReclaimedHumongousObjects.java<br>
the test is the slowest one, but after the split it fits the
budget.<br>
<br>
If someone has objections on adding/removing JPRT tests, please
speak up.<br>
<br>
Thanks, <br>
Dima<br>
<br>
