rollback

I'm new to Heroku. After pushing bad code to the server, I used heroku rollback to revert to a previous version. I then tried to clone this rollback to my computer with: git clone git@heroku.com:<project>.git <dir> Unfortunately, this clones the corrupted head, not the rollback. Is there a way to actually clone a specific previous version? When you do rollbacks, the head of your Heroku Git repo will no longer reflect the running state of you app. Check your releases: $ heroku releases Rel Change By When ---- ---------------------- ------------------- ------------- v52 Config add AWS_S3_KEY

I am aware that rollbacks can remove commits from the latest changeset in a local repository. However, is it possible to remove all the latest commits since the previous push without having to re-clone the share repository? You could make a new repo with hg clone : hg clone -r last_good_changeset localrepo newlocalrepo You can use the hg strip command, part of the mq extension: hg strip REV This will remove that revision + all its descendants. Before you try this, make a copy/clone of the repository to experiment in. If you are using mercurial eclipse, you can rollback once, then shelve those

When in a mysql innodb transaction, I would expect a duplicate key error to cause a rollback. It doesn't, instead it simply throws an error and continues on to the next command. Once the COMMIT command is reached, the transaction will be committed, sans the duplicate key causing command. Is this the expected behaviour? If so, how would one go about setting it up so that the transaction is rolled back instead of committed when such an error occurs? test environment: CREATE TABLE `test` ( `id` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 BEGIN; INSERT INTO test

I accidentally deleted some huge number of rows from a table... How can I roll it back? I executed the query using PuTTY . I'll be grateful if any of you can guide me safely out of this... If you didn't commit the transaction yet, try rollback . If you have already committed the transaction (by commit or by exiting the command line client), you must restore the data from your last backup. Omry Yadan If you haven't made a backup, you are pretty much fudged. Select0r A "rollback" only works if you used transactions . That way you can group queries together and undo all queries if only one of

I have a Mercurial repository that I use in local only... It's for my personal usage (so I don't "push" anywhere). I made a commit with 3 files, but after that I understood that I should do commit 4 files... Is there a way to "rollback" my last (latest, only one) commit, and "recommit" it with the correct files? (I don't know why, but my " Amend current revision " option is not active, so I can't use it...) You just need this command: hg rollback See: http://hgbook.red-bean.com/read/finding-and-fixing-mistakes.html . (Technically, this is deprecated as of version 2.7, August 2013, but I've yet
