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

I think affected teams should now safe guard all clones on individual machines, and wait until the IT team signals that systems are back to stable, really.
At that time we may need to re-push lost commits from our local clones. Perhaps even some lost tags are available from local clones. 


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



For now, waiting and not pushing anything seems to be the best strategy, 
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.

    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>

        Locally pulling doesn't provide anything newer than 2021-07-26. 
    Same for me.



        Is this an effect of the recent incident? 
    Probably, but I don't know. @Webmaster will have to comment.



        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:
