strange pushes on GitHub

[domi]

Hi everyone and specially Luca,

yesterday something strange has happen to many Jenkins repositories on GitHub (more then 50 Repos)…
Luca Milanesio seems have pushed to many many repositories without really changing anything - at least I have not seen anything changed.
If you look at the activity stream/feed at https://github.com/organizations/jenkinsci and go back to yesterday, you’ll find many pushes to many different repositories.
Maybe I’m wrong and someone has an easy explanation for this?
But for me this looks like someone did not really now how Git/GitHub works and accidentally pushed to every single repo - maybe someone else could also have a look and see if there is something broken now?

regards Domi

[Marcelo]

Domi, maybe it's related to this mail http://jenkins-ci.361315.n4.nabble.com/Jacoco-plugin-repo-reset-tt4680030.html.

Regards

Marcelo Rebasti

It seems like a lot of repositories are back to previous revisions. git-client-plugin's master now points to 1.4.3-SNAPSHOT whereas it should be pointing to 1.4.7-SNAPSHOT...

Definitely related, selenium-tests repo lost 17+ commits after such push.

[domi]

As I don’t know if Luca is following this list too, I’m adding Lucas mail on the to list… (got the email address from his GitHub account)

Please Luca can you explain what you have done to all this repositories?

regards Domi

I confirm we lost many commits. damned github that doesn't allow to disable the history rewrite at least on master branch. 

Last commit on Xcode repo is referencing one done by Jerome Lacoste 5 montages ago while KK worked on it recently. 

I don't know how we can restore everything easily. We need to find the recent hash and relative history in a clone we the push of yesterday was retrieved.

Hi all,

I have triggered an involuntary "forced push" last night on the list of Jenkins-CI plugins indicated below in this e-mail.

My apology 

I did not realise that I actually had forced push permissions and I do apologise for the inconvenience caused.

The operations pushed back the all the branches to around 1 month. The history is not lost and is still on the GitHub server but on detached branches.

The solution

I can raise a request to GitHub to provide the "reflog" of those repositories and restore the branches to the point before my forced push.

Alternatively the owners of those repositories can still perform a "forced push" to restore the correct position of the branches.

(if you would like to do so, please write to the mailing list so that we do not overlap the recovery operations)

The prevention

Can we prevent this to happen again ?

I personally do not work on any of those repositories but still have "forced push" permissions ... and so many other people have.

I don't see the value of having such power of "potential disruption" associated to my account :-( ... can we remove the forced push by default and enable on a case-by-case basis ?

--- * ---

If you would like to propose an alternative approach to resolve the problem, feel free to follow-up !

... and again ... accept my sincere apologies :-(

Luca.

[ogondza]

I have already asked Github support to provide hashes of former master positions and referenced this thread. Will report ASAP.

[Luca Milanesio]

*UPDATE*

I have just send the request to GitHub support on-line, looping them as well in this e-mail.

@GitHub Support: please consider this request as a matter of urgency, thank you.

Luca.

[Arnaud Héritier]

Thx guys for these details. We are all humans and subject of doing errors. 

I hope we'll have some help from github but I'm not sure they may spend many time to help us for an error not coming from their side. 

In any case it is recommended to NOT PULL current master branches from these repositories, your local copy may be more up-to-date. If you have a recent hash you can at least try to push them in github under a branch named "master-fix" the time we find the best solution to repare all master repositories. 

If you commited on these repositories since yesterday verify that you didn't started your work from the wrong old hash. 

Idea : in our CI server logs we should be able to find the lastest hash of each repo in the related plugin build. After that we have to find how to restore them. It's easy to do it when you have this commit locally but AFAIK it's not if it is only in the remote (you don't get orphelin commits when you clone a repo)

*UPDATE* after a cross-check I need to add 2 extra repositories to the list:

accurev-plugin
analysis-core-plugin

The total number of impacted repositories should then be: 186

@ALL: is there anyone with direct contact of some GitHub-er ? It would be best to resolve the problem *before* the start of the working week on Monday.

Thanks to everyone that contributed to resolve the problem !

Luca.

[Luca Milanesio]

Hi Arnaud,
thanks for the understanding :-) I am used to warn other people from doing any "forced push" ... and Murphy's law wanted this time happening to me :-(

Technically yes, but for the "customer relationship" and because it is an easy recovery (git reflog + git branch), they could make some effort to help us out.
JenkinsCI is possibly the largest customer they have worldwide ;-)

Yes, that's what I thought as well ... but definitely the "git reflog" on GitHub server would be more reliable.
The CI workspace (assuming that Git clones are not shallow copies) may have as well those commits as well, but again GitHub would be safer and better IMHO.

Hi,

I don't think GitHub.com has any possibilities for disabling force pushes, this seems to be exclusive to GH Enterprise only.

The JaCoCo repo where I initially noticed this was restored by Dominik Stadler (centic9) few minutes ago.

Marcus

[Mirko Friedenhagen]

Hello,

I saw these strange pushes as well, jobConfigHistory-plugin was
failing because master was reset to a commit which was two months old.
I see that https://github.com/jenkinsci/maven-hpi-plugin/tree/master
is pointing to an old commit as well, the new version 1.106 is much
newer than master.

That's really pitty :-( ... force push are dangerous, especially if you don't have control over the Git Server.

Typically recovering a force push is straightforward:

1. git reflog > look at the SHA-1 before the forced push

2. git branch -f <name> <sha-1>

But if you don't have control over the Git repo on the Server, that you need to prevent force push to happen: unless they want everyone to buy GH Enterprise !

I still hope GitHub will do 1. and 2. for us :-)

Luca.

[Dominik Stadler]

Hi,

I didn't know that this was a bigger problem and thus just pushed the previous commits again, in case of the jacoco-plugin repo it was easy as I just committed changes yesterday and thus could easily push the latest changes together with the missing commits.

The really bad thing in my view is that as a user of the repo you do not see at all that it happened. Git and Github is all about history of changes, but in this case your repo looks like a month ago with no visible trace on github that something newer was there at some time... Quite dangerous....

Dominik.

[Slide]

I did a force push to email-ext and it seems to be fine now.

Thanks,

[Arnaud Héritier]

In theory, to restore the master to the latest hash (and others branches - As I can see in Github organisation history) no --force will be required. You won't change the history, you just re-add missing commits on top of the old one.

I hope that Github will help us. That may save us a lot of time. Perhaps giving us a copy of all repositories could be enough and we may dig ourselves in reflogs to restore branches.

Yes that's really annoying that they don't allow us to block force push on some branches. Because of that when I migrated my company from subversion to Github I setup a daily external clone/backup process of all repositories in a case where we had such issue and we weren't easily able to identify a recent clone amonst ours developers (which is a children game in a company compared in an OSS like Jenkins)

[Christopher Orr]

With 678 members in the jenkinsci organisation, we're probably
relatively exceptional; I can't imagine GitHub have much incentive to
implement the type of fine-grained force-push permissions we would need.

Plus I think even with the number of members we have, git accidents are
very rare, i.e. it's likely easier to fix mistakes in git, than to
maintain a big set of permissions for new and existing users/repos.

BTW, out of curiosity, how did you manage to force push such a large
number of repositories at the same time? :)

Chris

GitHub model is based on pull requests and not on shared Git repositories: that's why protections against forced push is typically not needed (typically repo is pushed by only its maintainers and not by contributors).

The way we use GitHub with Jenkins is not very typical for  them :-)

Yes they are rare ! ... but when they happen you need to sort them out :-(

Problems with the Gerrit replication plugin ... unfortunate combination of three events (Murphy's law ?):

- working on a directory where I had the Jenkins plugins repos cloned (but outdated to around 1 month ago)

- having a Gerrit replication plugin pointing to that directory (I did not realised was using *forced push* that until later today)

- having the permissions of making *forced push* on repos that I did not work on (I did not realised that until today)

I have removed those local repos on my machine ... so can't do it again, but we need to sort out the mess in the meantime :-(

I am submitting now a patch to Gerrit replication plugin to *forbid* forced push by configuration: so at least I can block them from my side.

Possibly a bit late ... closing the gates when the sheep just escaped ;-(

Luca.

Yeah, that's unlucky.

One thing I sometimes do for repos where I have commit access, but don't
want to push, is to clone the repository via HTTP. That way, any
accidental attempts at pushing won't use my ssh key, and so GitHub will
prompt me for my password.

Regards,
Chris

Does anyone have news from GitHub ?
They haven't responded at all to my customer support request :-(

I wonder if we can use our all.git [1] somehow (in the worst case scenario
that github doesn't help us). When it try to clone it, it fails with remote
error and when looking into web UI the changes are already synchronized with
github. But IMHO still worth to investigate, orphan commits could still be
there

What is the recommended way to get a full restore, in the case where you do not happen to have a local clone of the repository which was cloned before the accident?

in worst case, we have a clone on jenkins.ci.cloudbees.com we can use to push back to github.

Yes, I think that would be a sensible approach.

As some of the people started already to push their up-to-date repo, it is better a push from the CI node rather than a "reset" from the GitHub guys at this stage.

HI there,

I just tried to connect to check out the plugin I maintain (ironmq-notifier).

I have lost access to the repo completely.

I suspect that since I'm new, my rights were reverted due to this somehow.

Could someone add me back into the plugin ironmq-notifier.

Could you list the repos that rejected the push and point us to the backup

next-build-number-plugin is missing 6 commits compared to my local copy. I
assume this is not the only one.

Hi,
just FIY, if your plugin is not on this list, this doesn't mean the commits
were successfully restored - e.g. one of my plugins (beaker-builder) is not on
the list and the last commit is 3 months old [1], while actual last commit is
one week old [2], so please double check your plugins

perforce-plugin.git has been restored from my local copy.

It may be beneficial to look into implementing finer grained access control for individual repos. For example, I thought that only myself, Oleg, and the Jenkins project owners had write access to the perforce plugin. If everyone has access to everything, then this sort of thing could happen again.

Hi all,

I have triggered an involuntary "forced push" last night on the list of Jenkins-CI plugins indicated below in this e-mail.

My apology 

I did not realise that I actually had forced push permissions and I do apologise for the inconvenience caused.

The operations pushed back the all the branches to around 1 month. The history is not lost and is still on the GitHub server but on detached branches.

The solution

I can raise a request to GitHub to provide the "reflog" of those repositories and restore the branches to the point before my forced push.

Alternatively the owners of those repositories can still perform a "forced push" to restore the correct position of the branches.

(if you would like to do so, please write to the mailing list so that we do not overlap the recovery operations)

If they can just create refs for all the tips of the affected branches
before a forced push in a distinct names, then we can write a script
that compares that with the current tip of the branches (which may or
may not be fixed by someone manually already) and do the right thing.

Yes, I was thinking about the same. The last run of this is Nov 9,
11:24pm in EST.

I really hope this is before the incident. But I'll find out soon.

You should push 'master' in these repos to a separate ref so that we can
compare.

Unfortunately, it appears that the last sync process has run after
luca's "push -f".

I'll hold on to this repo just in case, but resurrecting lost commits
from this appears hopeless.
