Conventions for this document
For clarity’s sake all examples in this document use customized bash prompt in order to indicate the current branch and whether or not there are staged changes. The branch is enclosed in parentheses, and a * next to the branch name indicates staged changes.
``` (my-branch*)$ git commit –amend
```
### Не проходит коммит в удаленый репозиторий выдавая сообщение об ошобке
Возможно переписать старый коммит новым, используем force push (-f) это перезапишет предыдущие изменения в репозитории. необходимо проверить в каком бранче вы находишся!!
Для этого необходим interactive rebase.
Сделайте пpull reuest текщего бранча master, you can rebase against your master branch. Make sure it is up to date:
(my-branch)$ git rebase -i master
If you aren’t working against another branch you’ll have to rebase relative to your HEAD. If you want to squash the last 2 commits, for example, you’ll have to rebase against HEAD~2. For the last 3, HEAD~3, etc.
(master)$ git rebase -i HEAD~2
After you run the interactive rebase command, you will see something like this in your text editor:
``` pick 01b2fd8 New awesome feature pick b729ad5 fixup pick e3851e8 another fix
Rebase 8074d12..b729ad5 onto 8074d12
# # Commands: # p, pick = use commit # r, reword = use commit, but edit the commit message # e, edit = use commit, but stop for amending # s, squash = use commit, but meld into previous commit # f, fixup = like “squash”, but discard this commit’s log message # x, exec = run command (the rest of the line) using shell # # These lines can be re-ordered; they are executed from top to bottom. # # If you remove a line here THAT COMMIT WILL BE LOST. # # However, if you remove everything, the rebase will be aborted. # # Note that empty commits are commented out ```
All the lines beginning with a # are comments, they won’t affect your rebase.
If you want to combine all your commits with the oldest (first) commit, you should edit the letter next to each commit except the first to say f:
pick 01b2fd8 New awesome feature
f b729ad5 fixup
f e3851e8 another fix
If you want to combine all your commit with the oldest commit and rename the commit, you should additionally add an r next to the first commit:
r 01b2fd8 New awesome feature
f b729ad5 fixup
f e3851e8 another fix
You can then rename the commit in the next text prompt that pops up.
``` Newer, awesomer features
Please enter the commit message for your changes. Lines starting
# with ‘#’ will be ignored, and an empty message aborts the commit. # rebase in progress; onto 8074d12 # You are currently editing a commit while rebasing branch ‘master’ on ‘8074d12’. # # Changes to be committed: # modified: README.md #
```
If everything is successful, you should see something like this:
(master)$ Successfully rebased and updated refs/heads/master.
Possible issues with interactive rebases
#### The rebase editing screen says ‘noop’
If you’re seeing this:
noop
That means you are trying to rebase against a branch that is at an identical commit, or is ahead of your current branch. You can try:
- making sure your master branch is where it should be
- rebase against
HEAD~2or earlier instead
If you are unable to successfully complete the rebase, you may have to resolve conflicts.
First run git status to see which files have conflicts in them:
```
(my-branch)$ git status
On branch my-branch
Changes not staged for commit:
(use “git add
modified: README.md ```
In this example, README.md has conflicts. Open that file and look for the following:
``` «««< HEAD some code ========= some code »»»> new-commit
```
You will need to resolve the differences between the code that was added in your new commit (in the example, everything from the middle line to new-commit) and your HEAD.
After you have resolved all conflicts and tested your code, git add the files you have changed, and then continue the rebase with git rebase --continue
(my-branch)$ git add README.md
(my-branch)$ git rebase --continue
If at any time you want to stop the entire rebase and go back to the original state of your branch, you can do so:
(my-branch)$ git rebase --abort
#### When I try to push, I get an error message:
To https://github.com/yourusername/repo.git
! [rejected] mybranch -> mybranch (non-fast-forward)
error: failed to push some refs to 'https://github.com/tanay1337/webmaker.org.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
Since rebasing replaces the old commit(s) with a new one, you must force push (-f) your changes. Be careful when you do this – always make sure you specify a branch!
(mybranch) $ git push origin mybranch -f
## I committed to master instead of a new branch
Check out a new branch, then return to your master branch
(master)$ git checkout -b new-branch
(new-branch)$ git checkout master
(master)$
Find out what the commit hash you want to set your master branch to (git log should do the trick). Then reset to that hash.
For example, if the hash of the commit that your master branch is supposed to be at is a13b85e:
(master)$ git reset --hard a13b85e
HEAD is now at a13b85e
## I made several commits on a single branch that should be on different branches
Say you are on your master branch. Running git log, you see you have made two commits:
``` (master)$ git log

Bug #14 - Fixed spacing on title
commit a13b85e984171c6e2a1729bb061994525f626d14 Author: Aki Rose akirose@exampledomain123.com Date: Tue Jul 21 01:12:48 2014 -0400
First commit ```
Let’s take note of our commit hashes for each bug (e3851e8 for #21, 5ea5173 for #14).
First, let’s reset our master branch to the correct commit (a13b85e):
(master)$ git reset --hard a13b85e
HEAD is now at a13b85e
Now, we can create a fresh branch for our bug #21 branch:
(master)$ git checkout -b 21
(21)$
Now, let’s cherry-pick the commit for bug #21 on top of our branch. That means we will be applying that commit, and only that commit, directly on top of whatever our head is at.
(21)$ git cherry-pick e3851e8
At this point, there is a possibility there might be conflicts. See the There were conflicts section in the interactive rebasing section above for how to resolve conflicts.
Now let’s create a new branch for bug #14, also based on master
(21)$ git checkout master
(master)$ git checkout -b 14
(14)$
And finally, let’s cherry-pick the commit for bug #14:
(14)$ git cherry-pick 5ea5173
