Hi, thanks for the patch! I have only one suggestion.
Instead of a new separate test for peerType, perhaps you could add a few more 
lines to one of the existing tests. Looking at this again perhaps the best one 
would be testConfigFileBackwardCompatibility() where it already checks that 
"server." and "clientPort" are being removed, you could add that "peerType" is 
also being removed.

Re: Test plan for ZK-1045 - Call for volunteers

[Rakesh Radhakrishnan]

I've uploaded feature document to the ZOOKEEPER-1045 jira, link =>
https://goo.gl/cvzG8A. I hope this doc will help you to setup a secured zk
cluster and start testing the feature. It would be really great to see the
test/review/usability feedback. Thanks!

   Removed README.md from the patch as I attached feature doc pdf doc 
separately in jira
   Replaced IOUtils.cleanup(LOG, sock) with simple sock.close(); as 
java-1.6 shows compilation errors.

[jira] [Commented] (ZOOKEEPER-2619) Client library reconnecting breaks FIFO client order

thanx diego, you did express well what i was trying to say. i also like your 
proposal. there are probably more details to work out, like how would it look 
for the C api? i like how it encapsulates nicely the relation between a 
sequence of operations, and your example does make a compelling argument for 
also including the sync api.

do we have some applications that we can use to validate the api? it would be 
nice to validate the design before we standardize it.

what i meant by "i think it's a good idea to document this issue in this jira" 
is that it's good that we have this jira to discuss the problem and potential 
solutions.

> According to the USENIX ATC 2010 
> [paper|https://www.usenix.org/conference/usenix-atc-10/zookeeper-wait-free-coordination-internet-scale-systems],
>  ZooKeeper provides "FIFO client order: all requests from a given client are

> applications written using the Java client library are unable to rely on this 
> guarantee, and any current application that does so is broken. Other client 
> libraries are also likely to be affected.
> Consider this application, which is simplified from the algorithm described 
> on Page 4 (right column) of the paper:
> {code}
>   zk = new ZooKeeper(...)
>   zk.createAsync("/data-23857", "...", callback)
>   zk.createSync("/pointer", "/data-23857")
> {code}
> Assume an empty ZooKeeper database to begin with and no other writers. 
> Applying the above definition, if the ZooKeeper database contains /pointer, 
> it must also contain /data-23857.
> Now consider this series of unfortunate events:
> {code}
>   zk = new ZooKeeper(...)
>   // The library establishes a TCP connection.
>   zk.createAsync("/data-23857", "...", callback)
>   // The library/kernel closes the TCP connection because it times out, and
>   // the create of /data-23857 is doomed to fail with ConnectionLoss. Suppose
>   // that it never reaches the server.
>   // The library establishes a new TCP connection.
>   zk.createSync("/pointer", "/data-23857")
>   // The create of /pointer succeeds.
> {code}
> That's the problem: subsequent operations get assigned to the new connection 
> and succeed, while earlier operations fail.
> In general, I believe it's impossible to have a system with the following 
> three properties:
>  # FIFO client order for asynchronous operations,
>  # Failing operations when connections are lost, AND
>  # Transparently reconnecting when connections are lost.
> To argue this, consider an application that issues a series of pipelined 
> operations, then upon noticing a connection loss, issues a series of recovery 
> operations, repeating the recovery procedure as necessary. If a pipelined 
> operation fails, all subsequent operations in the pipeline must also fail. 
> Yet the client must also carry on eventually: the recovery operations cannot 
> be trivially failed forever. Unfortunately, the client library does not know 
> where the pipelined operations end and the recovery operations begin. At the 
> time of a connection loss, subsequent pipelined operations may or may not be 
> queued in the library; others might be upcoming in the application thread. If 
> the library re-establishes a connection too early, it will send pipelined 
> operations out of FIFO client order.
> I considered a possible workaround of having the client diligently check its 
> callbacks and watchers for connection loss events, and do its best to stop 
> the subsequent pipelined operations at the first sign of a connection loss. 
> In addition to being a large burden for the application, this does not solve 
> the problem all the time. In particular, if the callback thread is delayed 
> significantly (as can happen due to excessive computation or scheduling 
> hiccups), the application may not learn about the connection loss event until 
> after the connection has been re-established and after dependent pipelined 
> operations have already been transmitted over the new connection.
> I suggest the following API changes to fix the problem:
>  - Add a method ZooKeeper.getConnection() returning a ZKConnection object. 
> ZKConnection would wrap a TCP connection. It would include all synchronous 
> and asynchronous operations currently defined on the ZooKeeper class. Upon a 
> connection loss on a ZKConnection, all subsequent operations on the same

[jira] [Commented] (ZOOKEEPER-2619) Client library reconnecting breaks FIFO client order

[Diego Ongaro (JIRA)]

Diego Ongaro commented on ZOOKEEPER-2619:

Thanks for the quick replies.

bq. In your first example, you're mixing the synchronous and the asynchronous 
API. We don't actually enforce that an application uses one or the other, but 
we do not recommend to mix synchronous and asynchronous calls precisely because 
of the reasons you're raising.

In my three-line example, it doesn't matter whether the second create is 
synchronous (mixing) or asynchronous (not mixing). Isn't it fine to issue a 
series of asynchronous calls ending with a synchronous call?

Summarizing the *{{reenableOps()}}* proposal so far, we have:
 - A new configuration option (say, "requireReenableOps") for an application to 
opt into calling {{reenableOps()}}. This would preserve backwards compatibility 
for existing clients, so the default would be to keep today's behavior.
 - Upon a connection loss, the client library would still reconnect 
automatically and issue pings as needed. However, with the configuration option 
set, it would continue to fail all requests (both synchronous and asynchronous).
 - After the application calls {{reenableOps()}}, the client library would 
permit new requests to use the new connection.

This would work, but in terms of API design, I can think of a couple of 
drawbacks:

- If we consider an application that's spread across various modules and/or 
thread boundaries, it has to be carefully designed with respect to 
{{reenableOps()}}, as this is a global property. I think this is what [~breed] 
was getting at with "it affects everything using the zookeeper handle". 
Specifically, every module/thread must be ready for a call to {{reenableOps()}} 
before it is safe to invoke, and until such time, the application won't make 
much progress.

- Most asynchronous code will need to know whether it's running under 
requireReenableOps=false or requireReenableOps=true. This might complicate a 
reusable library's internals and API, which may need to have different behavior 
depending on this setting.

The *{{getConnection()}}* proposal doesn't have these problems. Some modules of 
an application can continue issuing synchronous calls on the ZooKeeper object, 
others can issue (deprecated) asynchronous calls on the ZooKeeper object, and 
yet others can use ZKConnection objects, moving to new connections at their own 
pace with no application-level synchronization.

bq. it sounds to me that getConnection() and reenableOps() are basically the 
same. right? or are you proposing that when you get a ZKConnection object you 
can invoke the zookeeper operations on that?

You would invoke the operations directly on the ZKConnection object.

I do like the idea of the library automatically reconnecting for pings, and we 
could apply that to the {{getConnection()}} proposal too:
- The library would reconnect automatically to issue pings, as it does now.
- {{ZooKeeper.getConnection()}} would return the current ZKConnection object, 
which wraps the current TCP connection.
- Upon a connection loss, all subsequent operations on the same ZKConnection 
would return a Connection Loss error. The library would internally reconnect 
automatically, but it would not make this TCP connection availble via the old 
ZKConnection.
- Upon noticing a connection loss, the application would need to call 
{{ZooKeeper.getConnection()}} again to get the new ZKConnection object.

The ZKConnection object certainly needs to export the asynchronous methods that 
are in ZooKeeper today. I think it should also export the synchronous methods. 
I think these are both well-defined and useful in ZKConnection, as in my 
original example with {{createAsync()}} followed by {{createSync()}}.

I think the ZooKeeper class should continue to export non-deprecated 
synchronous methods as well. These would just be convenience wrappers that 
invoke {{getConnection()}} followed by the synchronous operation on that. Much 
ZooKeeper code is entirely synchronous, and as such, does not depend on FIFO 
client order. I see no reason to force churn upon that code.

I still think the asynchronous calls on the ZooKeeper class should be 
deprecated, since applications cannot rely on FIFO client order when using 
them. At a minimum, these should have a very clear warning to this effect, and 
applications should be encouraged to get a ZKConnection and then make 
asynchronous calls on that.

Ok, I'm even more confused now. I think [~wuwen] did it by mistake, but I'd 
like a confirmation. If so, let's just work on it in ZOOKEEPER-1394.
