I can't tell for certain. Looking a bit closer the code that starts the
server for the c tests does reference the clover jar, so my guess would
be that it does, but the messages from clover and the build, etc.. don't
shed any light. I didn't setup the zk clover stuff for hudson, cc'ing
Giri who might have insight.

Hi Patrick,
We are not using C clients so we are not worried about porting them to
Windows. Just out of curiosity, is there any way to confirm if the code
coverage results are a result of test-core-java. If not, I will run the
coverage tools locally.
I had tried the smoketests earlier, but I ran into some issues there. I
forgot to note down the problem. I will revisit and upload the results.
Thanks for your help.

Hi Mahadev,
Thanks for your response. Currently I am running ZK without
cygwin on
windows. I will give it a try on cygwin. I am not quite familiar
with
cppunit. Why will cppinit give me more confidence in native windows
libraries?
I have few more questions relevant to testing:
1. How much code coverage do we get with "test-core-java"? I see
68.8%
coverage on hudson
http://hudson.zones.apache.org/hudson/job/ZooKeeper-trunk/clover/.
Does
this measure the coverage from junit tests run from
"test-core-java"?
Right, afaik that's test-core-java.
I think if you plan to run in production under windows you would
want to run in win, not cygwin. If that's the case you'd have to
port the c client and c client tests to some windows specific compiler.
2. What would be a good and reliable set of tests that will help
me verify
that the cluster holding up fine on windows. I tried to run
systest and
generateload. But I am having issues with the tests (and also
understanding
the output of the tests since I am not familiar with the
source). The
systest did exit with output something ilke Test OK (1). I
presume this is a
good sign :-) generateLoad crashed and I will look into it
later. Please let
me know if you have any suggestions. Last few lines are shown below:
Well the best thing would be to run one's own tests for their
specific use cases. Short of that you've done the core set of tests
that we have available to us. You might try the smoke/latency tests:
http://github.com/phunt/zk-smoketest
in particular you can run the latency tests from a number of clients
in parallel and see the results.

HI Vishal,
I would be a good think to actually get cppunit working on
windows (rather
than dropping it) since it would make you more confident on
being able to
use the native libraries for windows.
Though there is already an open jira to try and compile
librarires without
CPPIUNIT being installed on the machines.
http://issues.apache.org/jira/browse/ZOOKEEPER-316
Would you want to try and take a shot at fixing the cppunit
tests?
Would be great to have cppunit tests working on cygwin!
Thanks

cppunit tests should be probably dropped for windows.
Also, one point to note the dataDir in zoo.cfg should
have UNIX path (or
double backslash instead of single backslash). I suppose
all Java
developers
might be already aware of that.

Then upgrade your clients. Code APIs on the client

I will let you know if I run into any windows

Hi,
I was able to start zookeeper on windows
using cygwin. I had to do
minor
changes to the shell scripts to use
cygpath wherever needed.
I will run a few tests and post the
progress. I greped through the
zookeeper
sources just to check if ZK is using any
native code.
I didn't find any, but just to confirm -
is ZK using native code.
I have talked to a few guys around and
they said it is fair to assume
that
the programs are portable (to Windows)
if they don't have native
code.
Just
wanted to check. Thanks.

Windows

zookeeper
tested
on windows. We are also
interested on using
Zookeeper on Win64
platform.
Is
Win64 supported? Are there
any plans to support
Win32/Win64 for
production?
If not, what would one need
to do support windows and
what would
be
the
estimated QA effort?
My use of ZK is exclusively
32/64bit linux, however I
can tell you
that
given that the client/server are
implemented in java it should
work.
Problems you might encounter
would be things like NIO issues with
the
JVM
implementation on windows.
Testing on windows? Pretty much
0 afaik. We do support development
on
cygwin, so provides some basic
exercising of the codepaths with the
windows
jvm, however it's not likely
production level qa.
This question (zk on win) has
come up once or twice before, I
haven't
seen
any followup from the users who
asked about it previously though.
3.3.0 has batch files for
running the server in windows,
give those
a
try.
Probably what you'd want to do
is run "ant test-core-java" or
similar
in
the
top of the ZK release directory.
This will run all the java tests
and
give
you some insight into status.
I'd be happy to work with you to
land
patches
that address issues with ZK on
windows. Depending on the interest
level
and
support from win users we could
support win as a dev/prod platform
at
some
point in the future - having
ongoing support for this would be
important
though (people interested in
testing/fixing under win I
mean). Try
exercising under windows and
create some JIRAs based on what you
find.
