[Yannic]

Could we cherry-pick 4162cc5 into Bazel 2.1? (Context: #10484)

[werkt]

Requesting cherry-pick of 9a823d9 into Bazel 2.1 (Context: #10566), addresses a NPE resulting in build failures.

[meteorcloudy]

Please cherry-pick 7e4c9d5 to fix #10572

[Helcaraxan]

For those not following the GitHub issue in question but #10356, which was re-opened yesterday, might be considered a release-blocker for 2.1.0.

[keith]

Any plans for when there will be another RC or the official 2.1.0 release?

[laurentlb]

I'll make another RC tomorrow.

[laurentlb]

I'm waiting for a resolution on #10356.

Apart from that, I'll cherry-pick:

• 733ac0f (for Bazel Query in Bazel 1.2.1 errors out due to bazel-internal code #10544)
• c94b147 (for Bazel CI: rules_jvm_external - Android instrumentation test example failing with Bazel@HEAD #10550)

Please tell me if I forgot another one. In some cases, I commented on the issue why I don't think a fix qualifies for a cherry-pick. Let me know if you feel strongly otherwise.

[philwo]

Just mentioning this here, so it doesn't get lost: This commit 2a8cc70 is the cherry-pick for #10356.

[laurentlb]

Sorry for the delay, I have been busy with some emergencies.

I've just tried to create rc2 with:
scripts/release/release.sh create --force_rc=2 2.1.0 41ec5a2 733ac0f c94b147 2a8cc70

But this is currently failing: bazelbuild/continuous-integration#929

[philwo]

I fixed the release pipeline so the error bazelbuild/continuous-integration#929 should no longer happen. We build Bazel with Xcode 10.3 now. I verified that the resulting binary still works fine on macOS High Sierra, so we don't regress in that regard.

Please cherry-pick this commit to fix a potential security issue that I accidentally introduced (it would have been in rc2, so let's skip that one) and then we can do rc3: d381c25

[laurentlb]

Creating candidate with:

scripts/release/release.sh create --force_rc=3 2.1.0 41ec5a2 733ac0f c94b147 2a8cc70 bdf34d7 d381c25

scripts/release/release.sh create --force_rc=4 2.1.0 41ec5a2 733ac0f c94b147 2a8cc70 bdf34d7 d381c25 eab39cc

(bdf34d7 was added to avoid a merge conflict)

[laurentlb]

Although there are still some issues in our testing infrastructure, the binaries can be tried here:
https://releases.bazel.build/2.1.0/rc4/index.html

[laurentlb]

The release announcement is ready: bazelbuild/bazel-blog#216

I'll do the release tomorrow.

I'm preparing Bazel 2.1.1 with one cherry-pick:

9a823d9: Prevent NPE on backwards seek on Chunker.

RELEASE_NUMBER=2.0.1
BASELINE_COMMIT=50514fc6c125750d7063d7feea2c302a44d2db6e

cd ~/bazel-release-$RELEASE_NUMBER
scripts/release/release.sh create $RELEASE_NUMBER $BASELINE_COMMIT

[philwo]

Bazel 2.1.1rc1 is now available for those that want to try it out.

You can download it from:
https://releases.bazel.build/2.1.1/rc1/index.html

[werkt]

I've tested the rc, and it works precisely how we hoped with my change. Can this be promoted to a full release?

[philwo]

@werkt I'll push it out tomorrow morning.

[werkt]

Any news on that release?

[philwo]

@werkt Pushing it now. Sorry for the delay. 😬

[or-shachar]

What about a docker image l.gcr.io/google/bazel:2.1.1 ? :-) who's in charge of those releases?

[jin]

Can this be closed?
