---------------------------------------
[~fpj ] & [~rakeshr] I agree, this code needs the community feedback in order
to convince you (and me) it's ready. It would be great if you could add it to
the contrib folder. Should I make a new patch that puts the code in a contrib
sub-folder? will I be able to post updates like it's "my" repo? will it be in
the trunk branch ?
I'd like to tell you a bit about why I did it this project.
3 months ago I started a new job in a place that uses mostly open source
software, which was totally new to me. My first task was to learn about MS
project Orleans and write a membership table implementation using ZK. I didn't
know what Orleans or ZK were. so I took [~ewhauser]'s code and started playing
with it. It worked most of the times, but there were some issues: sometimes I'd
get "connection lost" for no apparent reason, the tests weren't passing
consistently, no support for ZK multi and it wasn't async. When I told my boss
we need to find another solution, he said "write a new one". (he wasn't aware
of the size of the task, me neither)
I made a clone of 3.4.6 release tag of the official ZK repo, to base on the
latest stable code. I started with some static code conversion tools to get the
easy parts out of the way. As I'm not a java programmer, the conversion wasn't
easy (java selector almost killed me). Luckily, I am eloquent in c#. After
about a month of not much sleep, I had a working c# client. all tests were
passing consistently. but it wasn't async and the recipes weren't converted
yet, that took two more weeks. I'm still improving performance, memory
consumption and basically everything I can think of.
Note that this code will soon be tested heavily in staging and production,
since where I work we're rewriting our whole product with Orleans.
My personal goal is to make ZK available to any .NET programmer. this JIRA is a
step in that direction.
> A .NET C# version of ZooKeeper client 3.4.6 release
> ---------------------------------------------------
>
> Key: ZOOKEEPER-2209
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2209
> Project: ZooKeeper
> Issue Type: New Feature
> Affects Versions: 3.4.6
> Environment: .NET CoreCLR
> Reporter: Shay Hazor
> Assignee: Shay Hazor
> Labels: .NET, CoreCLR, async, c#
> Fix For: 3.4.6
>
> Attachments: ZOOKEEPER-2209.patch
>
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> Inspired by the work of ewhauser .
> I propose a C# Client that supports the current stable version of ZK 3.4.6.
> It was built by using static code conversion tools followed by manual editing
> and C# implementations of java selector and other java constructs.
> A great measure was taken to follow the logic of the java version. In fact,
> the code is almost identical. Thus allowing easy evolution alongside the java
> version.
> Main features:
> * fully .NET async, not explicit threads used
> * all relevant unit tests have been converted and passing consistently
> * recipes are included, will be converted to async soon
> * Code is 100% CoreCLR compliant
> * NuGet package -
> [ZooKeeperNetEx|https://www.nuget.org/packages/ZooKeeperNetEx] is already
> integrated in [Microsoft Project Orleans|https://github.com/dotnet/orleans]
> as the only open-source membership provider.
