[DISCUSS] Releasing Apache Flink 1.12.2

[curcur]

Hey devs,

One of the major issues that have not been resolved in Apache Flink 1.12.1
is "unaligned
checkpoint recovery may lead to corrupted data stream"[1]. Since the
problem is now fixed and
it is critical to the users, I would like to kick off a discussion on
releasing Flink 1.12.2 that
includes unaligned checkpoint fixes.

I would like to volunteer myself for managing this release. But I noticed
that some of the release
steps may require committer authorities. Luckily, Piotr and Roman are very
kind to provide help
on such steps.

Apart from the unaligned checkpoint issue, please let us know in this
thread if there are any
other fixes that we should try to include in this version. I'll try to
communicate with the issue
owners and come up with a time estimation next week.

Hi Yuan,


I am a Firefox user and I just fixed a long lasting bug https://github.com/apache/flink/pull/14848 , wish this would be merged in this release.


Best wishes

Hi,

Thanks Yuan for bringing up this topic.

+1 for the quick 1.12.2 release.

As Yuan mentioned, me and Roman can help whenever committer rights will be
required.

> I am a Firefox user and I just fixed a long lasting bug
https://github.com/apache/flink/pull/14848 , wish this would be merged in
this release.

I will push to speed up review of your PR. Let's try to merge it before
1.12.2, but at the same time I wouldn't block the release on this bug.

Best,
Piotrek

Thanks for volunteering for being our release manager Yuan :-)

+1 for a timely bug fix release.

I will try to review the PR for FLINK- 20417 [1] which is a good fix to
include in the next bug fix release. We don't have to block the release on
this fix though.

Thanks for being our release manager Yuan.

We found a out of memory issue [1] which will affect most batch jobs thus I
think
it would be great if we can include this fix in 1.12.2.

+1 for releasing 1.12.2, and thanks for volunteering to be our release
manager Yuan.

Besides the mentioned issues, I could see two more blockers with 1.12.2 as
fix version [1] and need some tracking:
* FLINK-21013 <https://issues.apache.org/jira/browse/FLINK-21013> Blink
planner does not ingest timestamp into StreamRecord
* FLINK- 21030 <http://Broken job restart for job with disjoint graph> Broken
job restart for job with disjoint graph

Best Regards,
Yu

Thanks Yuan for driving 1.12.2.
+1 for releasing 1.12.2

One comment about FLINK-21030 [1]: I hope to fix it this week. But there
are still some uncertainties. The underlying problem is older than 1.12.
Hence, the suggestion is to not block the 1.12.2 release because of
FLINK-21030 [1]. I will leave it as a blocker issue, though, to underline
that it should be fixed for 1.13.

Best,
Matthias

[Matthias]

Fabian and I were investigating strange behavior with stop-with-savepoint
not terminating when using the new fromSource to add a source to a job
definition. I created FLINK-21323 [1] to cover the issue. This might not be
a blocker for 1.12.2 since this bug would have been already around since
1.11, if I'm not mistaken? I wanted to bring this to your attention,
anyway. It would be good if someone more familiar with this part of the
source code could verify our findings and confirm the severity of the issue.

Best,
Matthias

Thanks very much for your replies!

I've been reaching out to the owners of the issues/blockers mentioned
above. By now, we have

Blocker Issues:

   -

   https://issues.apache.org/jira/browse/FLINK-21013: fixed
   -

   https://issues.apache.org/jira/browse/FLINK-21030: estimate to finish by
   the end of this week, but should not be a release blocker

Best to Include:

   -

   https://issues.apache.org/jira/browse/FLINK-20417: fixed
   -

   https://issues.apache.org/jira/browse/FLINK-20663: estimate to finish by
   the end of this week, but should not be a release blocker
   -

   https://github.com/apache/flink/pull/14848: under review


Hence, let's target *a feature freeze on Feb. 15, next Monday*!

If there is any concern on anything, please feel free to contact me.

Best
Yuan

include in 1.12.2 as well.

Hey devs,

I'm very glad to announce that all known blocking issues for release-1.12.2
have been resolved.

release-1.12.2 will freeze at:
commit 1f8be1fd7b2b37a124e4d2b8080d08e259bdf095

Roman and I are about to prepare the first release candidate and many
thanks to Roman for agreeing to do the release together with me!

We will start a separate voting thread as soon as RC1 is created.

Best,

Yuan

[roman]

Hi everyone,

The issue which caused the previous RC cancellation is now resolved [1].

There are two more issues that we'd like to include in 1.12.2 [2][3].
Yuan and I are going to prepare the next RC (#2) once they are resolved.

Please let us know if there are any other issues blocking the RC.
Currently, the dashboard doesn't show any blockers [4].

Roman

If time allows then we could also include FLINK-21030 [1]. We are about to
merge this fix.

[Matthias]

There's a test instability which I assume is caused by FLINK-21028 [1]. I
created FLINK-21515 [2] to cover this issue.
Could somebody verify that? I validated already that this issue appears on
master as well without the changes added in FLINK-21030 [3].

Best,
Matthias

Thanks for the update and for reporting the issue Matthias.

I see that FLINK-21030 is now resolved [1]
I can confirm that FLINK-21515 is indeed a test stability not affecting
production code (I've published a patch to fix it).

Therefore, I will proceed to building the next RC
from e9af362f0caa16e75e66aa1403c62666e77f98f0.

Regards,
Roman
