We will take advantage of this +to eradicate spam from the history of the doc branch. + +This is a useful tool, but it is considered bad practise to rewrite the +history of public repositories. If your software's repository is public, you +should make it clear that the history of the `doc` branch in your repository +is unstable. + +Once you have been spammed, use `git rebase` to remove the spam commits from +the history. Assuming that your `doc` branch was split off from a branch +called `master`: + + # ensure you are on the doc branch + $ git branch + * doc + master + $ git rebase --interactive master + +In your editor session, you will see a series of lines for each commit made to +the `doc` branch since it was branched from `master` (or since the last merge +back into `master`). Delete the lines corresponding to spammy commits, then +save and exit your editor. + +Caveat: if there are no commits you want to keep (i.e. all the commits since +the last merge into master are either spam or spam reverts) then `git rebase` +will abort. Therefore, this approach only works if you have at least one +non-spam commit to the documentation since the last merge into `master`. For +this reason, it's best to wait until you have at least one +commit you want merged back into the main history before doing a rebase, +and until then, tackle spam with reverts. |
