Re: [cross-project-issues-dev] git rollback?

Hi Mikael

At least two projects are reporting what appears to be a GIT roll backto a backup state.

The time of the outage is therefore less interesting than the time ofthe backup state that determines what is, at least currently, lost.

The last weekend's outage was on our primary backend storage (whererepos hosted at git.eclipse.org <http://git.eclipse.org> are stored).The outage started at 9:20pm/9:30pm EDT on July 31st.

Since then, live replicas have been rsync'd back. What you see isapparent data loss. I don't have any information whether this is dueto how the storage has been restored. I cannot tell you if we havemore up-to-date data that could be restored for your git repo.

Hopefully, the date/time of the outage given above should help yougather the required clues to bring back a working git repo.

I think affected teams should now safe guard all clones on individualmachines, and wait until the IT team signals that systems are back tostable, really.

At that time we may need to re-push lost commits from our localclones. Perhaps even some lost tags are available from local clones.

For that task of re-pushing, teams may need to coordinate, whichcommits in which order need to be re-played. A good indicator is the"Tested-by" line in commit messages, which signals a commit that hasonce gone through the gerrit exercise and thus should be seen as partof the "official" history. A bugzilla query for recently resolvedbugs would be helpful - if bugzilla queries are reliable again.

For now, waiting and not pushing anything seems to be the beststrategy, right?

    Hi Sravan

    In the absence of any clues from the IT team can you please
    identify the time to which GIT / downloads have been rolled back
    so that we can all be aware of what is, at least currently, lost
    at the EF.

        Hi

        Same for OCL.

        I pushed a branch commit that successfully refreshed
        everything on the branch with the result that the IT team now
        need to resolve a merge of the rolled back copy, the
        incremental backed up history and the post 'no-outage' changes.

              o Has the jdt.core git been rolled back?

            I don't know - it certainly looks like it. AFAIK the git
            URL links you posted are mirrors of the gerrit repos. The
            gerrit repos are the primary IIUC. In gerrit the
            referenced review is still active -
            _https://git.eclipse.org/r/c/jdt/eclipse.jdt.core/+/183569_
            <https://git.eclipse.org/r/c/jdt/eclipse.jdt.core/+/183569> -
            so it looks like gerrit took a step backwards, rather
            than just git by itself. For the latter commit, the
            gerrit entry is "broken"
            _https://git.eclipse.org/r/c/jdt/eclipse.jdt.core/+/183573_
            <https://git.eclipse.org/r/c/jdt/eclipse.jdt.core/+/183573>
              o Locally pulling doesn't provide anything newer than
                2021-07-26.

            Same for me.

              o Is this an effect of the recent incident?

            Probably, but I don't know. @Webmaster will have to comment.

              o Any other project seeing similar effects?

            Yes. CDT has at least one gerrit from July 31st that has
            lost a patchset and associated comments. I have them in
            my email, but they are missing from gerrit:

            _https://git.eclipse.org/r/c/cdt/org.eclipse.cdt/+/183568_
            <https://git.eclipse.org/r/c/cdt/org.eclipse.cdt/+/183568>

            The metadata in the email is below, and there is no such
            comment in the gerrit:

            Gerrit-Project: cdt/org.eclipse.cdt
            Gerrit-Branch: master
            Gerrit-Change-Id: I96589e86bee561aa200a4a4487549305765d6409
            Gerrit-Change-Number: 183568
            Gerrit-PatchSet: 4
            Gerrit-Owner: Mat Booth <_mat.booth@gmail.com_
            <mailto:mat.bo...@gmail.com>>
            Gerrit-Reviewer: CDT Bot <_cdt-bot@eclipse.org_
            <mailto:cdt-...@eclipse.org>>
            Gerrit-Comment-Date: Sat, 31 Jul 2021 20:04:45 +0000

            You can also see evidence of the mismatch in CDT's build
            jobs.

            
_https://ci.eclipse.org/cdt/job/cdt-verify-test-cdt-ui-only-pipeline/3450/_
            
<https://ci.eclipse.org/cdt/job/cdt-verify-test-cdt-ui-only-pipeline/3450/> and
            
_https://ci.eclipse.org/cdt/job/cdt-verify-test-cdt-ui-only-pipeline/3451/_
            
<https://ci.eclipse.org/cdt/job/cdt-verify-test-cdt-ui-only-pipeline/3451/> both
            built PS4, but 3450 built the now lost patchset, so the
            sha1 for the same ref is different:
