Re: Ticket review checklist

Hi Igniters,

I would like to refresh review checklist a little bit. Currently it [1] 
contains section against lambda Lambda expressions and Stream API. As 
far as I know it is not true anymore. Currently both features have 
theirs usage in core module. What is a state of affairs for a subject? 
Are there some well-known cases where e.g. lambdas are not applicable? 
Should we document it?

I personally think that we could delete entire Java 8 section from 
checklist (and Java 5 as well). I understand that every tool should be 
used judiciously but I doubt that all cases can be covered in short 
checklist.

Re: Ticket review checklist

Posted by Павлухин Иван <vo...@gmail.com>.
Hi Dmitriy,

I agree with you about lambdas. For me they are quite useful and I believe
that this language feature is a solid and well proven part of modern Java.

I still feel that current statement in our guidelines should be rephrased.
But if others are ok with it then let's keep it as is.

Re: Ticket review checklist

Posted by Dmitriy Pavlov <dp...@gmail.com>.
Hi Ivan,

Unfortunately, the review checklist does not work as well as it could. I
hope the situation will change in the nearest future, I think we should
come back to this idea and encourage contributors and reviewers to use the
list.

As for lambda's: some Igniters feel confident about it, and some Igniters
don't. My opinion it is perfectly ok to use it if usage is local node only,
is there is no chance lambda is serialized to the network. If there is such
chance it is better to avoid it.

Sincerely,
Dmitriy Pavlov

Re: Ticket review checklist

Posted by Павлухин Иван <vo...@gmail.com>.
Vladimir,

First of all, statements in Java 8 section [1] looks kind of prohibitive
for me. When a new contributor see words "preferred" and "avoided in most
cases" he most likely will not use such features (like I did). If a
statement is not prohibitive in practice it could be at least rephrased.

A bit about expressiveness. I written a code during working on a real
ticket. The case is quite common in Ignite codebase. You can find example
with couple of approaches in snippet [2]. For me approach with lambdas is
expressive, compact and simple.

What do you think?

Re: Ticket review checklist

Posted by Vladimir Ozerov <vo...@gridgain.com>.
Hi Ivan,

From what I see we do not restrict contributors to use lambdas and streams.
Document states that plain collections and anonymous classes are
*preferred*. This is not obligatory requirement, and it seems reasonable to
me, because when developing complex projects at times it is better to have
more expressive code, than less non-obvious code which makes dozens
operations in a single string.

Or may be there are any other statements in the checklist which prevents
users from using Java 8 features?

Vladimir.
