Subject Re: [VOTE] Release Apache Dubbo (Incubating) 2.6.3 [RC5]
Date Sun, 09 Sep 2018 06:56:42 GMT
Sorry, I just got some time back to this thread.
I just went through the dev discussion of the dubbo and found out
dubbo community are planning the next release cut by discussion the
bug fix list first.  I'm sure we could do it better in the next
release.

Here are my +1 for this vote.
I can build the code from source.
The artifacts were signed with right key.

For the UT test error, is only related to system property setting
which will not effect the end user.
Just a quick note for binary release,  it only includes the dubbo
jars. It could be more convenience for the end user if we can include
the third party dependencies jars in the binary release.

have some UTs (3-4 as I know) that are not stable enough themselves, which means they cannot
verify features as expected or they may sometimes mis-warn us with failures limited to their
own bad logic, and even worse over time, we may be less alert to UT failures. I would suggest
we fix these unstable UTs as soon as possible, or at least, if they are not on the schedule
now, we should list all these unstable UTs and the possible failures and reasons for failure
to reduce the confusion of developers and verifiers.

we have learned that there’re still some things lacking in the community to guarantee regular
Apache releases with high quality and efficiency. The Dubbo community has worked on with the
following aspects to improve that:
