Stepan,
Thank you for the information.
As far as JUnit didn't print what result was expected to get I
inserted
printing to the test and got the following:
Expected host: localhost.localdomain
Recieved host: localhost
Why do you expect that on Linux "localhost.localdomain" should be
returned?
Well, that is because both RI/Harmony return this value on my test
machines(Redhat ES 3, Redhat 9 and latest stable Debian), and I didn't
expect this value is dependent on configuration(or Linux distribution?
), but as your test result shows, it probably does! So would you tell me
your linux distro version and configuration( for example, what it looks
like of the item on localhost in /etc/hosts)? so that I can check if
this constant value(localhost.localdomain) is platform dependent.
Hi Paulex,
I run tests on SUSE LINUX ES 9, file /etc/hosts contains the next entry:
127.0.0.1 localhost
Ah, we haven't tested on SUSE! That should be the cause, seems the
different Linux distro has different default setting of /etc/hosts:(.
Currently I have a linux workstation, file /porc/version show it is
"Linux version 2.4.21-15.ELsmp ([EMAIL PROTECTED]) (gcc
version 3.2.3 20030502 (Red Hat Linux 3.2.3-34)) #1 SMP Thu Apr 22 00:18:24
EDT 2004", and its /etc/hosts tells:
127.0.0.1 localhost.localdomain localhost
google tells me that Debian3.1 and redhat 8.0 also contain this field
defaultly.
Shall we call it as platform-release-dependency problems? :)
I agree to consider it as a platform-release-dependency problem. And
seems I need to modify the test cases to handle this issue. I'll raise a
separate JIRA for this.
The are no entries with " localhost.localdomain". Today also I run these
tests on WinXP - all DatagramChannelTest passed but SocketChannelTest
(testReadByteBuffer_NonBlocking_ReadWriteRealTooLargeData) failed with the
following diagnostics:
expected:<24820> but was:<65536>
junit.framework.AssertionFailedError: expected:<24820> but was:<65536> at
org.apache.harmony.tests.java.nio.channels.SocketChannelTest.testReadByteBuffer_NonBlocking_ReadWriteRealTooLargeData
(SocketChannelTest.java :2579) at
java.lang.reflect.AccessibleObject.invokeV(
AccessibleObject.java:205)
This one should be another story, it should be the case that depends on
race condition, as we guessed at first. I'll also include this kind of
problem into the JIRA.
Is this enough for you to identify a problem? Please let me know if you
need
more info.
Thank you, Stepan, the information is very helpful.
Thanks,
Stepan.
And I'll also look more inside to see if there can be other cause except
for the possible platform difference.
Thanks,
Stepan.
And before everything's OK, I'm fine if you choose to add
DatagramChannelTest into exclude list, by adding it to Ln.94 of
modules/nio/make/common/build.xml, just as ServerSocketChannelTest.
Sorry for the inconvenience caused.
And there are new 15 test failures. So now if I'll make a code
update
or a
bug fix how I can be 100% sure that I don't do any regression?
Currently if a commit breaks the Harmony classlib build a
notification
with
subject: "[continuum] BUILD FAILURE: Classlib/linux.ia32" will be
send
to
harmony-commits mailing list. Is it possible to have the same for
tests?
I
mean that after completing automatic build the existing classlib
tests
suite
should be run. If there are failing tests then a report notification
with
corresponding subject will be send.
Thanks,
