Wanted to assist dubbo community on issue #2884

[Imteyaz Khan]

Hi All,
   Trust you all are doing well. I am new to this community or even new to
any open source development community. Had a chance to go through one of
the dubbo github issue #2884('We need more code comments'), which was
marked as 'good first issue'. So thought it could be a good start for me to
start from here, but being new to open source and also to dubbo I am very
nervous from where and how to start. I will be great if team can help me
and guide me too to assist you in any way I can.

Regards
Imteyaz

No matter it's an increase or decrease compared to the previous quarter, we
are focusing more on processing issues and pull requests on the GitHub. In
my own opinion, I think this is quite critical to build a strong and active
community. That is, we hope we can process issues/PR more quickly in the
future :)

Re: About the comments coverage of the code

[Ian Luo]

What I suggest is to revisit and enhance the existing javadoc/comments
before consider to add more:
1. Enhance JavaDoc for all API. For this part, we may need some helps from
native speakers
2. Revisit the current existing comments, and make it easier to understand

Just my two cents,
-Ian.

Folks,

Let's vote :) We have not been to Guangzhou and Nanjing, so their priority
for holding next meetup is higher, but we definitely revisit Beijing,
Shanghai later in the next year.

not yet.
However, I have personally reviewed some of the benchmark information.
Don't worry, we will give our benchmark when submitting PR.


 Can he be on the mailing list to discuss this?



of course. All the exchanges will come here.  Apache way.  :)

Re: [DRAFT] Dubbo incubator Report - December 2018

[Huxing Zhang]

Add more explanations:

Since last report, the communities has welcomed 6 new committers and 2
new PPMC members. Comparing to last quarter, when we have 4 new
committers and no new PPMC members. The number of contributors have
grown from 119 to 144.

I think the following events have played key parts of helping the
community to grow:
0. Ian Luo and Jun Liu have delivered a a talk "Introducing Apache
Dubbo(Incubating): What is Dubbo and How it Works" in ApacheCon
Montreal.
1. With a discussion with mentors in ApacheCon Montreal, the Dubbo
community and learned a lot about how to build the community. One key
takeaway is that to keep the bar for becoming a  committer low.
2. Dave Fisher has becoming our new mentor.
3. Apache project meetup in ShangHai has been held in Oct 13th
4. Our mentor Justin has visited Alibaba, and give a talk on
navigating through the incubator process
5. COSCon'18 has been held in Shenzhen, China, where Craig L.Russell,
Dave Fisher, and Justin have delivered a lot of wonderful talks about
ASF.

The closed PRs actually drops from 287 to 190, one of the reason I can
think is that some of the committers were busy with other things, with
their activities back and community continues to grow , I remain
positive that the stats can grow in next few months.

Agree.

I saw someone from India who would like to contribute in this issue.
We need to break them down to small tasks.

Maybe separate them by modules or something smaller and manage them by
Github Project?

About the comments coverage of the code

[yuhang xiu]

Recently dubbo held an offline meetup. When discussing with many
participants, many people have suggested that dubbo has very few comments.

Comments are very important for us to understand the code. If our comments
are few, it is very unfriendly for new developers.

I created a new issue[1] to track this. We need more developers to
contribute notes. I will continue to follow up on this matter.

[1] https://github.com/apache/incubator-dubbo/issues/2884

Use longObjectMap to increase performance

[yuhang xiu]

Hi, community
At present, there are many Map type maps in dubbo. When using
this kind of map, jdk performs automatic package.

We can use longObjectMap(or intObjectMap or sth else) to replace these maps
and add some performance.

Similarly, I have opened an issue[1] to track the progress. Of course, I
will still find a new person to complete the work, we will comb and replace
these maps together. I have found a person. We will start the organizing
work and the program, and will be synchronized to the mailing list and
issue. (
He still has some work at the moment, so the discussion may be delayed for
a few days)

By the way, there are a few pr content that is simple, I think we can do a
review and merge them. The issue list is here:
https://github.com/apache/incubator-dubbo/pull/2831
https://github.com/apache/incubator-dubbo/pull/2809
https://github.com/apache/incubator-dubbo/pull/2802
https://github.com/apache/incubator-dubbo/pull/2788

Can someone take a look?
