If you just want to get the latest source and you don't require the ability to push changes to the MariaDB repository, you can use the following command to check out the latest 10.5 branch:
git clone -b 10.5 https://github.com/MariaDB/server.git
git config --global user.name "Ivan Ivanov" git config --global user.email "[email protected]"
git clone [email protected]:MariaDB/server.git cd server git checkout 10.5
git config pull.ff only git config --global alias.ff "merge --ff-only"
In git commit messages are normally formatted as
subject body more body ...
That is, the first line is considered a *subject*, much like email subject. Many git commands and pages on github only show the commit subject, not the complete comment. After the subject goes an empty line, then the detailed description of the comment. Please, structure your commit comments this way, don't forget the empty line.
This is an important concept, and git branches do not have equivalents in bzr.
In Bazaar, we all used to have one shared repository, within which there were many branches. This seems to be impossible with git?
In Git, each repository has only one branch that is currently checked out.
git branch
To see which branches exists locally and remotely:
git branch --all
git checkout branch-name
Note that if the output from git branch --all is remotes/origin/XXX you should just use XXX as branch name.
branch clone old_directory new_directory cd new_directory git remote set-url origin [email protected]:MariaDB/server.git git pull
git reset --hard HEAD^
If you get the following error on pull:
shell> git pull X11 forwarding request failed on channel 0 fatal: Not possible to fast-forward, aborting.
Instead of removing your copy and then clone, you can do:
git reset --hard origin/##branch-name##
bb- are automatically put into the buildbot. CAVEAT UTILITOR. Check the manual before running!
bzr status is git status bzr diff is git diff bzr log is git log bzr revert is git reset --hard bzr revert filename is git checkout filename bzr parent is git remote -v (but there are more detailed commands) bzr parent to-default-mariadb-repo git remote set-url origin [email protected]:MariaDB/server.git bzr push is git push REMOTENAME BRANCHNAME. REMOTENAME is typically "origin", for example: git push origin HEAD:10.3-new-feature. The HEAD: stands for "from current branch". bzr clean-tree --ignored is git clean -Xdf (note the capital X!) bzr root is git rev-parse --show-toplevel bzr missing --mine-only is git cherry -v origin (kind-of). GUIs
bzr gcommit is git citool bzr viz is gitk bzr gannotate is git gui blame In the MariaDB project, it is a good idea (and a long tradition since MySQL Ab) to have all your commits sent to a [email protected] mailing list. It allows others to follow the progress, comment, etc.
A script and instructions on how to setup commit triggers in Git are here: http://bazaar.launchpad.net/~maria-captains/mariadb-tools/trunk/files/head:/git_template/ . Jira task for commit trigger was MDEV-6278.
If you add code on behalf of someone else, please attribute the code to the original author:
git citool and move changed files to staged. commit, abort instead git commit --author="Original author name <email_address>" The above is needed as git citool can't handle the --author option.
At the end of the pull request page there is a button "Merge pull request" and next to it a link "command line instructions". Click the link, you'll see something like
Step 1: From your project repository, check out a new branch and test the changes.
git checkout -b mariadb-server-joeuser-cool-feature 10.3 git pull https://github.com/joeuser/mariadb-server cool-feature
Step 2: Merge the changes and update on GitHub.
git checkout 10.3 git merge --no-ff mariadb-server-joeuser-cool-feature git push origin 10.3
Note where to pull from — https://github.com/joeuser/mariadb-server cool-feature.
Now, checkout the branch you want to merge it to, say, bb-10.3-stage, and do the following
git fetch https://github.com/joeuser/mariadb-server cool-feature
git checkout FETCH_HEAD
git rebase @{-1}
Now's the time to compile the code, test it, fix, if necessary. Then
git checkout @{-1}
git ff @{-1}
If you want to do small changes to the pull request, do it in a separate commit, after git rebase @{-1} above. If you want to do big changes to the pull request, perhaps you shouldn't merge it in the first place, but ask the contributor to fix it?
git show
You are working on a branch (NEW_FEATURE) and would like to have into that branch all changes from the main branch (10.1).
git checkout 10.1 git pull git checkout NEW_FEATURE git rebase 10.1
You've just fixed and committed a bug in the main 10.1 branch and want to merge it with the latest 10.1. Often a rebase is better in this case. Assuming your current checked out branch is 10.1:
git fetch origin git rebase origin/10.1
This will work even if you have done multiple commits in your local 10.1 tree.
What to do when you have fixed a bug in the main tree but notices that someone has changed the tree since you pulled last time. This approach ensures that your patch is done in one block and not spread out over several change sets.
git clone 10.1 cd 10.1 < fix a bug here> git citool git push # ^ and the above fails, because someone has pushed to 10.1 in between git branch tmp # ^ copy our work to branch named 'tmp' get checkout 10.1 git reset --hard HEAD^ # ^ remove our work from '10.1' local branch' git pull # ^ get changes from remote git checkout tmp git rebase 10.1 # ^ switch to 'tmp' and try to rebase 'tmp' branch on top of 10.1 branch. # here you will be asked to merge if necessary git checkout 10.1 git pull --ff . tmp # ^ switch back to the '10.1' branch, and pull from 'tmp' branch. git branch -D tmp #^ this removes the tmp. branch git push
