Hi @avif. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

From go side lgtm, I'm wondering if there's no release on lua cookies module yet, instead of tracking a commit.

Thanks

Hey, is there any chance someone can resurrect this PR?

CC @Gacko @rikatz @tao12345666333 if/when possible, please review.

@avif @miskr-instructure this needs rebase

@Gacko

I cannot give a lot of review regarding the actual change, but I definitely have serious doubts about changing the Lua Resty Cookie module.

Actually it was already changed from cloudflare/[email protected] to utix/lua-resty-cookie#9533f47 by this change and was reverted (possibly by mistake) by this change, I just bumped the version.

Could you please elaborate on why this is needed? Normally we discourage such bumps and changes to the modules being built into NGINX in PRs and would prefer having a discussion first.

Sure, the cloudflare repo is archived and so has no newer versions. As for the bump in version, Partitioned is new cookie semantics and did not exist in the currently used package (pre or post revert).

Sorry to say, but I can remember serious issues in the past and therefore we're just a bit more cautious when it comes to such changes.

No need to apologize, I for one appreciate the cautious approach.
