Proposal for reworked ZK web site generation: CMS -> jekyll

[Patrick Hunt]

Hi folks. After the issues a few weeks ago during the 3.4.11 release trying
to get the site published and INFRA no longer supporting CMS I've gone
through the effort to look at what other options are available. I reviewed
a number of other ASF sites and it looks like jekyll with markdown is very
popular. Additionally INFRA is currently supporting gitpubsub - which means
that if we can generate a static site and commit the results to git INFRA
will take that and update the live production site. Basic workflow would
then be:

1) manually edit the markdown pages which are the source of the website
(similar to what we do today)
2) generate the static website using jekyll, review this as the "staged"
site (locally)
3) once we're happy with it commit/push the changes to the markdown source
4) commit/push the changes to the generated/static site content - gitpubsub
will then push those live to zookeeper.apache.org.

This is pretty close to what we are doing today as part of a release but
it's streamlined and takes CMS out of the equation (the old content
management which is no longer supported by INFRA).

I've converted the current website over to this new model and staged the
change in my personal github repo. Please take a look as I'd like to move
over to this new model soon - let's say about a week from today for
feedback.

Any committers out there please give this a +1 if you're on board - otw let
me know your concerns.

This would be the source of the website, markdown/jekyll based:
https://github.com/phunt/zookeeper/tree/website

This is the generated site (html) - pushing this branch would cause asf
INFRA to re-publish the site (gitpubsub):
https://github.com/phunt/zookeeper/tree/asf-site

Notice these are orphan branches (no history aside from the recent docs
changes) and both of these branches would live within the existing/current
zookeeper git repo. So if you clone the zookeeper repo you'll have the
website as well - no longer necessary to checkout multiple repos in order
to update the website.

Patrick

[GitHub] zookeeper issue #420: ZOOKEEPER-2924. Refactor tests of LoadFromLogTest.java

[afine]

Github user afine commented on the issue:

https://github.com/apache/zookeeper/pull/420
  
@phunt I think it's fine to always modify the `snapCount`. My concern was 
primarily modifying it once the zookeeper server was running created 
nondeterministic behavior.

In addition, I don't think most of these tests make any assertions that 
could be impacted by the `snapCount`. So I think the current iteration of the 
tests is fine.

Also, +1 on removing the lines instead of commenting them out and using a 
smaller snapCount.

Otherwise lgtm.

[GitHub] zookeeper issue #420: ZOOKEEPER-2924. Refactor tests of LoadFromLogTest.java

[phunt]

Github user phunt commented on the issue:

https://github.com/apache/zookeeper/pull/420
  
I thought @afine 's comment was that only the two tests that actually need 
the snapcount to be set should have it set. The other two tests should not have 
it set. Am I mistaken?

My concern (remaining) is that we've effectively changed the parameters of 
the tests if we change these values. I'm assuming the original author verified 
that the tests failed before submitting the fix (incl tests). However unless we 
do that ourselves I'd be concerned that the test no longer recreates the 
environment that originally caused the problem. As such that's why I was 
suggesting we ensure the original values are used.

Unless you both looked at what the tests are doing and are confident? (I 
didn't look that deep) I do see that num messages is 300. If we do go this 
route perhaps we should use the smaller of the two original values? (50 iiuc).

And please remove the lines themselves (rather than just commenting them 
out).

Thanks!

> From https://builds.apache.org/job/ZooKeeper_branch34_openjdk7/1682/
> Same issue happens in jdk8 and jdk9 builds as well.
> Issue has already been fixed by 
> https://issues.apache.org/jira/browse/ZOOKEEPER-2484 , but I believe that the

> As a consequence, when exception happens during test execution, ZK test 
> server doesn't get shutdown properly and still listening on the port bound to

> As mentioned above there could be 2 approaches to address this:
> #1 Wrap cleanup code block with finally
> #2 Use JUnit's Before-After methods for initialization and cleanup

[GitHub] zookeeper pull request #425: Add keys for the Zxid from the stat command

[alexbb]

GitHub user alexbb opened a pull request:

https://github.com/apache/zookeeper/pull/425

Add keys for the Zxid from the stat command

Add keys for the zxid and its component pieces: epoch and transaction 
counter. These are not reported by the 'mntr' command so they must be obtained 
from 'stat'. The counter is useful for tracking transaction rates, and epoch is 
useful for tracking leader churn.

 zk_zxid - the 64bit zxid from ZK
 zk_zxid_counter - the lower 32 bits, AKA the counter
 zk_zxid_epoch   - the upper 32 bits, AKA the epoch

You can merge this pull request into a Git repository by running:

$ git pull https://github.com/alexbb/zookeeper add_zxid_stats

Alternatively you can review and apply these changes as the patch at:

https://github.com/apache/zookeeper/pull/425.patch

To close this pull request, make a commit to your master/trunk branch
with (at least) the following in the commit message:

This closes #425

> "ServerName" field in SSL Hello packet(the proxy served on SSL only). but the 
> Hello packets that zk client sended do proxy do not contain the "ServerName"

> sslEngine = sslContext.createSSLEngine();
> Actually the sslContext provide another factory method that receives the 
> hostName and port parameter.
> public final SSLEngine createSSLEngine(String hostName, int port)
> If we call this method to create the SSLEngine, then the proxy will know 
> which zk cluster it really want to access.

@phunt @afine thanks for the detail comments.
I think @afine made a good point, I've removed setting the SnapCount 
explicitly in each test, leaving only a common setting in the setUp method. 
Only those 2 tests really care about the setting and with a little 
modification, they can share the same setting.
