# Get Zulip code
|
||||||
|
|
||||||
|
Zulip uses a **forked-repo** and **[rebase][gitbook-rebase]-oriented
|
||||||
|
workflow.**. This means that all contributors create a fork of the [Zulip
|
||||||
|
repository][github-zulip] they want to contribute to and then submit pull
|
||||||
|
requests to the upstream repository to have their contributions reviewed and
|
||||||
|
accepted. We also recommend you work on feature branches.
|
||||||
|
|
||||||
|
## Step 1a: Create your fork
|
||||||
|
|
||||||
|
The following steps you'll only need to do the first time you setup a machine
|
||||||
|
for contributing to a given Zulip project. You'll need to repeat the steps for
|
||||||
|
any additional Zulip projects ([list][github-zulip]) that you work on.
|
||||||
|
|
||||||
|
The first thing you'll want to do to contribute to Zulip is fork ([see
|
||||||
|
how][github-help-fork]) the appropriate [Zulip repository][github-zulip]. For
|
||||||
|
the main server app, this is [zulip/zulip][github-zulip-zulip].
|
||||||
|
|
||||||
|
## Step 1b: Clone to your machine
|
||||||
|
|
||||||
|
Next, clone your fork to your local machine:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git clone --config pull.rebase git@github.com:christi3k/zulip.git
|
||||||
|
Cloning into 'zulip'
|
||||||
|
remote: Counting objects: 86768, done.
|
||||||
|
remote: Compressing objects: 100% (15/15), done.
|
||||||
|
remote: Total 86768 (delta 5), reused 1 (delta 1), pack-reused 86752
|
||||||
|
Receiving objects: 100% (86768/86768), 112.96 MiB | 523.00 KiB/s, done.
|
||||||
|
Resolving deltas: 100% (61106/61106), done.
|
||||||
|
Checking connectivity... done.
|
||||||
|
```
|
||||||
|
|
||||||
|
(The `--config pull.rebase` option configures Git so that `git pull`
|
||||||
|
will behave like `git pull --rebase` by default. Using `git pull
|
||||||
|
--rebase` to update your changes to resolve merge conflicts is
|
||||||
|
expected by essentially all of open source projects, including Zulip.
|
||||||
|
You can also set that option after cloning using `git config --add
|
||||||
|
pull.rebase true`, or just be careful to always run `git pull
|
||||||
|
--rebase`, never `git pull`).
|
||||||
|
|
||||||
|
Note: If you receive an error while cloning, you may not have [added your ssh
|
||||||
|
key to GitHub][github-help-add-ssh-key].
|
||||||
|
|
||||||
|
## Step 1c: Connect your fork to Zulip upstream
|
||||||
|
|
||||||
|
Next you'll want to [configure an upstream remote
|
||||||
|
repository][github-help-conf-remote] for your fork of Zulip. This will allow
|
||||||
|
you to [sync changes][github-help-sync-fork] from the main project back into
|
||||||
|
your fork.
|
||||||
|
|
||||||
|
First, show the currently configured remote repository:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git remote -v
|
||||||
|
origin git@github.com:YOUR_USERNAME/zulip.git (fetch)
|
||||||
|
origin git@github.com:YOUR_USERNAME/zulip.git (push)
|
||||||
|
```
|
||||||
|
|
||||||
|
Note: If you've cloned the repository using a graphical client, you may already
|
||||||
|
have the upstream remote repository configured. For example, when you clone
|
||||||
|
[zulip/zulip][github-zulip-zulip] with the GitHub desktop client it configures
|
||||||
|
the remote repository `zulip` and you see the following output from `git remote
|
||||||
|
-v`:
|
||||||
|
|
||||||
|
```
|
||||||
|
origin git@github.com:YOUR_USERNAME/zulip.git (fetch)
|
||||||
|
origin git@github.com:YOUR_USERNAME/zulip.git (push)
|
||||||
|
zulip https://github.com/zulip/zulip.git (fetch)
|
||||||
|
zulip https://github.com/zulip/zulip.git (push)
|
||||||
|
```
|
||||||
|
|
||||||
|
If your client hasn't automatically configured a remote for zulip/zulip, you'll
|
||||||
|
need to with:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git remote add upstream https://github.com/zulip/zulip.git
|
||||||
|
```
|
||||||
|
|
||||||
|
Finally, confirm that the new remote repository, upstream, has been configured:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git remote -v
|
||||||
|
origin git@github.com:YOUR_USERNAME/zulip.git (fetch)
|
||||||
|
origin git@github.com:YOUR_USERNAME/zulip.git (push)
|
||||||
|
upstream https://github.com/zulip/zulip.git (fetch)
|
||||||
|
upstream https://github.com/zulip/zulip.git (push)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 2: Set up the Zulip development environment
|
||||||
|
|
||||||
|
If you haven't already, now is a good time to install the Zulip development environment
|
||||||
|
([overview][zulip-rtd-dev-overview]). If you're new to working on Zulip or open
|
||||||
|
source projects in general, we recommend following our [detailed guide for
|
||||||
|
first-time contributors][zulip-rtd-dev-first-time].
|
||||||
|
|
||||||
|
## Step 3: Configure Travis CI (continuous integration)
|
||||||
|
|
||||||
|
This step is optional, but recommended.
|
||||||
|
|
||||||
|
The Zulip Server project is configured to use [Travis CI][travis-ci]
|
||||||
|
to test and create builds upon each new commit and pull
|
||||||
|
request. Travis CI is free for open source projects and it's easy to
|
||||||
|
configure for your own fork of Zulip. After doing so, Travis CI will
|
||||||
|
run tests for new refs you push to GitHub and email you the outcome
|
||||||
|
(you can also view the results in the web interface).
|
||||||
|
|
||||||
|
Running Travis CI against your fork can help save both you and the
|
||||||
|
Zulip maintainers time by making it easy to test a change fully before
|
||||||
|
submitting a pull request. We generally recommend a worfklow where as
|
||||||
|
you make changes, you use a fast edit-refresh cycle running individual
|
||||||
|
tests locally until your changes work. But then once you've gotten
|
||||||
|
the tests you'd expect to be relevant to your changes working, push a
|
||||||
|
branch to Travis CI to run the full test suite before you create a
|
||||||
|
pull request. While you wait for Travis CI to run, you can start
|
||||||
|
working on your next task. When the tests finish, you can create a
|
||||||
|
pull request that you already know passes the tests.
|
||||||
|
|
||||||
|
First, sign in to [Travis CI][travis-ci] with your GitHub account and authorize
|
||||||
|
Travis CI to access your GitHub account and repositories. Once you've done
|
||||||
|
this, Travis CI will fetch your repository information and display it on your
|
||||||
|
[profile page][travis-ci-profile]. From there you can enable integration with
|
||||||
|
Zulip. ([See screen cast](../_static/zulip-travisci.gif).)

# Collaborate
|
||||||
|
|
||||||
|
## Fetch another contributor's branch
|
||||||
|
|
||||||
|
What happens when you would like to collaborate with another contributor and
|
||||||
|
they have work-in-progress on their own fork of Zulip? No problem! Just add
|
||||||
|
their fork as a remote and pull their changes.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git remote add <username> https://github.com/<username>/zulip.git
|
||||||
|
$ git fetch <username>
|
||||||
|
```
|
||||||
|
|
||||||
|
Now you can checkout their branch just like you would any other. You can name
|
||||||
|
the branch anything you want, but using both the username and branch name will
|
||||||
|
help you keep things organized.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout -b <username>/<branchname>
|
||||||
|
```
|
||||||
|
|
||||||
|
You can choose to rename the branch if you prefer:
|
||||||
|
```
|
||||||
|
git checkout -b <custombranchname> <username>/<branchname>
|
||||||
|
```
|
||||||
|
|
||||||
|
## Checkout a pull request locally
|
||||||
|
|
||||||
|
Just as you can checkout any user's branch locally, you can also checkout any
|
||||||
|
pull request locally. GitHub provides a special syntax
|
||||||
|
([details][github-help-co-pr-locally]) for this since pull requests are
|
||||||
|
specific to GitHub rather than Git.
|
||||||
|
|
||||||
|
First, fetch and create a branch for the pull request, replacing *ID* and
|
||||||
|
*BRANCHNAME* with the ID of the pull request and your desired branch name:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git fetch upstream pull/ID/head:BRANCHNAME
|
||||||
|
```
|
||||||
|
|
||||||
|
Now switch to the branch:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout BRANCHNAME
|
||||||
|
```
|
||||||
|
|
||||||
|
Now you work on this branch as you would any other.
|
||||||
|
|
||||||
|
Note: you can use the scripts provided in the tools/ directory to fetch pull
|
||||||
|
requests. You can read more about what they do [here][tools-PR].
|
||||||
|
```
|
||||||
|
tools/fetch-rebase-pull-request <PR-number>
|
||||||
|

# Quick start: How Zulip uses Git and GitHub
|
||||||
|
|
||||||
|
This quick start provides a brief overview of how Zulip uses Git and GitHub.
|
||||||
|
|
||||||
|
Those who are familiar with Git and GitHub should be able to start contributing
|
||||||
|
with these details in mind:
|
||||||
|
|
||||||
|
- We use **GitHub for source control and code review.** To contribute, fork
|
||||||
|
[zulip/zulip][github-zulip-zulip] (or the appropriate
|
||||||
|
[repository][github-zulip], if you are working on something else besides
|
||||||
|
Zulip server) to your own account and then create feature/issue branches.
|
||||||
|
When you're ready to get feedback, submit a work-in-progress (WIP) pull
|
||||||
|
request. *We encourage you to submit WIP pull requests early and often.*
|
||||||
|
|
||||||
|
- We use a **[rebase][gitbook-rebase]-oriented workflow.** We do not use merge
|
||||||
|
commits. This means you should use `git fetch` followed by `git rebase`
|
||||||
|
rather than `git pull` (or you can use `git pull --rebase`). Also, to prevent
|
||||||
|
pull requests from becoming out of date with the main line of development,
|
||||||
|
you should rebase your feature branch prior to submitting a pull request, and
|
||||||
|
as needed thereafter. If you're unfamiliar with how to rebase a pull request,
|
||||||
|
[read this excellent guide][github-rebase-pr].
|
||||||
|
|
||||||
|
We use this strategy in order to avoid the extra commits that appear
|
||||||
|
when another branch is merged, that clutter the commit history (it's
|
||||||
|
popular with other large projects such as Django). This makes
|
||||||
|
Zulip's commit history more readable, but a side effect is that many
|
||||||
|
pull requests we merge will be reported by GitHub's UI as *closed*
|
||||||
|
instead of *merged*, since GitHub has poor support for
|
||||||
|
rebase-oriented workflows.
|
||||||
|
|
||||||
|
- We have a **[code style guide][zulip-rtd-code-style]**, a **[commit message
|
||||||
|
guide][zulip-rtd-commit-messages]**, and strive for each commit to be *a
|
||||||
|
minimal coherent idea* (see **[commit
|
||||||
|
discipline][zulip-rtd-commit-discipline]** for details).
|
||||||
|
|
||||||
|
- We provide **many tools to help you submit quality code.** These include
|
||||||
|
[linters][zulip-rtd-lint-tools], [tests][zulip-rtd-testing], continuous
|
||||||
|
integration with [Travis CI][travis-ci], and [mypy][zulip-rtd-mypy].
|
||||||
|
|
||||||
|
- We use [zulipbot][zulip-rtd-zulipbot-usage] to manage our issues and
|
||||||
|
pull requests to create a better GitHub workflow for contributors.
|
||||||
|
|
||||||
|
Finally, take a quick look at [Zulip-specific Git scripts][zulip-rtd-zulip-tools],
|
||||||
|
install the [Zulip developer environment][zulip-rtd-dev-overview], and then
|
||||||
|
[configure your fork for use with Travis CI][zulip-git-guide-travisci].
|
||||||
|
|
||||||
|

|
||||||
|

||||||
|
The following sections will help you be awesome with Zulip and Git/GitHub in a
|
||||||
|
rebased-based workflow. Read through it if you're new to git, to a rebase-based

# Create a pull request
|
||||||
|
|
||||||
|
When you're ready for feedback, submit a pull request. Pull requests
|
||||||
|
are a feature specific to GitHub. They provide a simple, web-based way
|
||||||
|
to submit your work (often called "patches") to a project. It's called
|
||||||
|
a *pull request* because you're asking the project to *pull changes*
|
||||||
|
from your fork.
|
||||||
|
|
||||||
|
If you're unfamiliar with how to create a pull request, you can check
|
||||||
|
out GitHub's documentation on
|
||||||
|
[creating a pull request from a fork][github-help-create-pr-fork]. You
|
||||||
|
might also find GitHub's article
|
||||||
|
[about pull requests][github-help-about-pr] helpful. That all said,
|
||||||
|
the tutorial below will walk you through the process.
|
||||||
|
|
||||||
|
## Work in progress pull requests
|
||||||
|
|
||||||
|
In the Zulip project, we encourage submitting work-in-progress pull
|
||||||
|
requests early and often. This allows you to share your code to make
|
||||||
|
it easier to get feedback and help with your changes. Prefix the
|
||||||
|
titles of work-in-progress pull requests with **[WIP]**, which in our
|
||||||
|
project means that you don't think your pull request is ready to be
|
||||||
|
merged (e.g. it might not work or pass tests). This sets expectations
|
||||||
|
correctly for any feedback from other developers, and prevents your
|
||||||
|
work from being merged before you're confident in it.
|
||||||
|
|
||||||
|
## Step 1: Update your branch with git rebase
|
||||||
|
|
||||||
|
The best way to update your branch is with `git fetch` and `git rebase`. Do not
|
||||||
|
use `git pull` or `git merge` as this will create merge commits. See [keep your
|
||||||
|
fork up to date][keep-up-to-date] for details.
|
||||||
|
|
||||||
|
Here's an example (you would replace *issue-123* with the name of your feature branch):
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout issue-123
|
||||||
|
Switched to branch 'issue-123'
|
||||||
|
|
||||||
|
$ git fetch upstream
|
||||||
|
remote: Counting objects: 69, done.
|
||||||
|
remote: Compressing objects: 100% (23/23), done.
|
||||||
|
remote: Total 69 (delta 49), reused 39 (delta 39), pack-reused 7
|
||||||
|
Unpacking objects: 100% (69/69), done.
|
||||||
|
From https://github.com/zulip/zulip
|
||||||
|
69fa600..43e21f6 master -> upstream/master
|
||||||
|
|
||||||
|
$ git rebase upstream/master
|
||||||
|
|
||||||
|
First, rewinding head to replay your work on top of it...
|
||||||
|
Applying: troubleshooting tip about provisioning
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 2: Push your updated branch to your remote fork
|
||||||
|
|
||||||
|
Once you've updated your local feature branch, push the changes to GitHub:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git push origin issue-123
|
||||||
|
Counting objects: 6, done.
|
||||||
|
Delta compression using up to 4 threads.
|
||||||
|
Compressing objects: 100% (4/4), done.
|
||||||
|
Writing objects: 100% (6/6), 658 bytes | 0 bytes/s, done.
|
||||||
|
Total 6 (delta 3), reused 0 (delta 0)
|
||||||
|
remote: Resolving deltas: 100% (3/3), completed with 1 local objects.
|
||||||
|
To git@github.com:christi3k/zulip.git
|
||||||
|
+ 2d49e2d...bfb2433 issue-123 -> issue-123
|
||||||
|
```
|
||||||
|
|
||||||
|
If your push is rejected with error **failed to push some refs** then you need
|
||||||
|
to prefix the name of your branch with a `+`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git push origin +issue-123
|
||||||
|
Counting objects: 6, done.
|
||||||
|
Delta compression using up to 4 threads.
|
||||||
|
Compressing objects: 100% (4/4), done.
|
||||||
|
Writing objects: 100% (6/6), 658 bytes | 0 bytes/s, done.
|
||||||
|
Total 6 (delta 3), reused 0 (delta 0)
|
||||||
|
remote: Resolving deltas: 100% (3/3), completed with 1 local objects.
|
||||||
|
To git@github.com:christi3k/zulip.git
|
||||||
|
+ 2d49e2d...bfb2433 issue-123 -> issue-123 (forced update)
|
||||||
|
```
|
||||||
|
|
||||||
|
This is perfectly okay to do on your own feature branches, especially if you're
|
||||||
|
the only one making changes to the branch. If others are working along with
|
||||||
|
you, they might run into complications when they retrieve your changes because
|
||||||
|
anyone who has based their changes off a branch you rebase will have to do a
|
||||||
|
complicated rebase.
|
||||||
|
|
||||||
|
## Step 3: Open the pull request
|
||||||
|
|
||||||
|
If you've never created a pull request or need a refresher, take a look at
|
||||||
|
GitHub's article [creating a pull request from a
|
||||||
|
fork][github-help-create-pr-fork]. We'll briefly review the process here.
|
||||||
|
|
||||||
|
The first step in creating a pull request is to use your web browser to
|
||||||
|
navigate to your fork of Zulip. Sign in to GitHub if you haven't already.
|
||||||
|
|
||||||
|
Next, navigate to the branch you've been working on. Do this by clicking on the
|
||||||
|
**Branch** button and selecting the relevant branch. Finally, click the **New
|
||||||
|
pull request** button.
|
||||||
|
|
||||||
|
Alternatively, if you've recently pushed to your fork, you will see a green
|
||||||
|
**Compare & pull request** button.
|
||||||
|
|
||||||
|
You'll see the *Open a pull request* page:
|
||||||
|
|
||||||
|
![images-create-pr]
|
||||||
|
|
||||||
|
Provide a **title** and first comment for your pull request. Remember to prefix
|
||||||
|
your pull request title with [WIP] if it is a [work-in-progress][wip-prs].
|
||||||
|
|
||||||
|
If your pull request has an effect on the visuals of a component, you might want
|
||||||
|
to include a screenshot of this change or a GIF of the interaction in your first
|
||||||
|
comment. This will allow reviewers to comment on your changes without having to
|
||||||
|
checkout your branch; you can find a list of tools you can use for this over
|
||||||
|
[here][screenshots-gifs].
|
||||||
|
|
||||||
|
When ready, click the green **Create pull request** to submit the pull request.
|
||||||
|
|
||||||
|
Note: **Pull request titles are different from commit messages.** Commit
|
||||||
|
messages can be edited with `git commit --amend`, `git rebase -i`, etc., while
|
||||||
|
the title of a pull request can only be edited via GitHub.
|
||||||
|
|
||||||
|
# Update a pull request
|
||||||
|
|
||||||
|
As you get make progress on your feature or bugfix, your pull request, once
|
||||||
|
submitted, will be updated each time you [push commits][self-push-commits] to
|
||||||
|
your remote branch. This means you can keep your pull request open as long as
|
||||||
|
you need, rather than closing and opening new ones for the same feature or
|
||||||
|
bugfix.
|
||||||
|
|
||||||
|
It's a good idea to keep your pull request mergeable with Zulip upstream by
|
||||||
|
frequently fetching, rebasing, and pushing changes. See [keep your fork up to
|
||||||
|
date][keep-up-to-date] for details. You might also find this excellent
|
||||||
|
article [How to Rebase a Pull Request][edx-howto-rebase-pr] helpful.
|
||||||
|
|
||||||
|
And, as you address review comments others have made, we recommend posting a
|
||||||
|
follow-up comment in which you: a) ask for any clarifications you need, b)
|
||||||
|
explain to the reviewer how you solved any problems they mentioned, and c) ask
|
||||||
|
for another review.

|
||||||
|
## Changes on (local) working tree
|
||||||
|
|
||||||
|
Display changes between index and working tree (what is not yet staged for commit):
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git diff
|
||||||
|
```
|
||||||
|
|
||||||
|
Display changes between index and last commit (what you have staged for commit):
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git diff --cached
|
||||||
|
```
|
||||||
|
|
||||||
|
Display changes in working tree since last commit (changes that are staged as
|
||||||
|
well as ones that are not):
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git diff HEAD
|
||||||
|
```
|
||||||
|
|
||||||
|
## Changes within branches
|
||||||
|
|
||||||
|
Use any git-ref to compare changes between two commits on the current branch.
|
||||||
|
|
||||||
|
Display changes between commit before last and last commit:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git diff HEAD^ HEAD
|
||||||
|
```
|
||||||
|
|
||||||
|
Display changes between two commits using their hashes:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git diff e2f404c 7977169
|
||||||
|
```
|
||||||
|
|
||||||
|
## Changes between branches
|
||||||
|
|
||||||
|
Display changes between tip of topic branch and tip of master branch:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git diff topic master
|
||||||
|
```
|
||||||
|

We highly recommend you create an ssh key if you don't already have
|
||||||
|
one and [add it to your GitHub account][github-help-add-ssh-key]. If
|
||||||
|
you don't, you'll have to type your GitHub username and password every
|
||||||
|
time you interact with GitHub, which is usually several times a day.
|
||||||
|
|
||||||
|
We also highly recommend the following:
|
||||||
|
|
||||||
|
- [Configure Git][gitbook-config] with your name and email and
|
||||||
|
[aliases][gitbook-aliases] for commands you'll use often. We
|
||||||
|
recommend using your full name (not just your first name), since
|
||||||
|
that's what we'll use to give credit to your work in places like the
|
||||||
|
Zulip release notes.
|
||||||
|
- Install the command auto-completion and/or git-prompt plugins available for
|
||||||
|
[Bash][gitbook-other-envs-bash] and [Zsh][gitbook-other-envs-zsh].
|
||||||
|
|
||||||
|
## Get a graphical client
|
||||||
|
|
||||||
|
Even if you're comfortable using git on the command line, having a graphic
|
||||||
|
client can be useful for viewing your repository. This is especially when doing
|
||||||
|
a complicated rebases and similar operations because you can check the state of
|
||||||
|
your repository after each command to see what changed. If something goes
|
||||||
|
wrong, this helps you figure out when and why.
|
||||||
|
|
||||||
|
If you don't already have one installed, here are some suggestions:
|
||||||
|
|
||||||
|
- macOS: [GitX-dev][gitgui-gitxdev]
|
||||||
|
- Ubuntu/Linux: [git-cola][gitgui-gitcola], [gitg][gitgui-gitg], [gitk][gitgui-gitk]
|
||||||
|
- Windows: [SourceTree][gitgui-sourcetree]
|
||||||
|
|
||||||
|
If you like working on the command line, but want better visualization and
|
||||||
|
navigation of your git repo, try [Tig][tig], a cross-platform ncurses-based
|
||||||
|
text-mode interface to Git.
|
||||||
|
|
||||||
|
And, if none of the above are to your liking, try [one of these][gitbook-guis].

# Important Git terms
|
||||||
|
|
||||||
|
When you install Git, it adds a manual entry for `gitglossary`. You can view
|
||||||
|
this glossary by running `man gitglossary`. Below we've included the git terms
|
||||||
|
you'll encounter most often along with their definitions from *gitglossary*.
|
||||||
|
|
||||||
|
## branch
|
||||||
|
A "branch" is an active line of development. The most recent commit
|
||||||
|
on a branch is referred to as the tip of that branch. The tip of
|
||||||
|
the branch is referenced by a branch head, which moves forward as
|
||||||
|
additional development is done on the branch. A single Git
|
||||||
|
repository can track an arbitrary number of branches, but your
|
||||||
|
working tree is associated with just one of them (the "current" or
|
||||||
|
"checked out" branch), and HEAD points to that branch.
|
||||||
|
|
||||||
|
## cache
|
||||||
|
Obsolete for: index
|
||||||
|
|
||||||
|
## checkout
|
||||||
|
The action of updating all or part of the working tree with a tree
|
||||||
|
object or blob from the object database, and updating the index and
|
||||||
|
HEAD if the whole working tree has been pointed at a new branch.
|
||||||
|
|
||||||
|
## commit
|
||||||
|
As a noun: A single point in the Git history; the entire history of
|
||||||
|
a project is represented as a set of interrelated commits. The word
|
||||||
|
"commit" is often used by Git in the same places other revision
|
||||||
|
control systems use the words "revision" or "version". Also used as
|
||||||
|
a short hand for commit object.
|
||||||
|
|
||||||
|
As a verb: The action of storing a new snapshot of the project's
|
||||||
|
state in the Git history, by creating a new commit representing the
|
||||||
|
current state of the index and advancing HEAD to point at the new
|
||||||
|
|
||||||
|
## fast-forward
|
||||||
|
A fast-forward is a special type of merge where you have a revision
|
||||||
|
and you are "merging" another branch's changes that happen to be a
|
||||||
|
descendant of what you have. In such these cases, you do not make a
|
||||||
|
new mergecommit but instead just update to their revision. This will
|
||||||
|
happen frequently on a remote-tracking branch of a remote
|
||||||
|
repository.
|
||||||
|
|
||||||
|
## fetch
|
||||||
|
Fetching a branch means to get the branch's head ref from a remote
|
||||||
|
repository, to find out which objects are missing from the local
|
||||||
|
object database, and to get them, too. See also git-fetch(1).
|
||||||
|
|
||||||
|
## hash
|
||||||
|
In Git's context, synonym for object name.
|
||||||
|
|
||||||
|
## head
|
||||||
|
A named reference to the commit at the tip of a branch. Heads are
|
||||||
|
stored in a file in $GIT_DIR/refs/heads/ directory, except when
|
||||||
|
using packed refs. (See git-pack-refs(1).)
|
||||||
|
|
||||||
|
## HEAD
|
||||||
|
The current branch. In more detail: Your working tree is normally
|
||||||
|
derived from the state of the tree referred to by HEAD. HEAD is a
|
||||||
|
reference to one of the heads in your repository, except when using
|
||||||
|
a detached HEAD, in which case it directly references an arbitrary
|
||||||
|
commit.
|
||||||
|
|
||||||
|
## index
|
||||||
|
A collection of files with stat information, whose contents are
|
||||||
|
stored as objects. The index is a stored version of your working
|
||||||
|
tree. Truth be told, it can also contain a second, and even a third
|
||||||
|
version of a working tree, which are used when merging.
|
||||||
|
|
||||||
|
## pull
|
||||||
|
Pulling a branch means to fetch it and merge it. See also git-
|
||||||
|
pull(1).
|
||||||
|
|
||||||
|
## push
|
||||||
|
Pushing a branch means to get the branch's head ref from a remote
|
||||||
|
repository, find out if it is a direct ancestor to the branch's
|
||||||
|
local head ref, and in that case, putting all objects, which are
|
||||||
|
reachable from the local head ref, and which are missing from the
|
||||||
|
remote repository, into the remote object database, and updating
|
||||||
|
the remote head ref. If the remote head is not an ancestor to the
|
||||||
|
local head, the push fails.
|
||||||
|
|
||||||
|
## rebase
|
||||||
|
To reapply a series of changes from a branch to a different base,
|
||||||
|
and reset the head of that branch to the result.

# How Git is different
|
||||||
|
|
||||||
|
Whether you're new to Git or have experience with another version control
|
||||||
|
system (VCS), it's a good idea to learn a bit about how Git works. We recommend
|
||||||
|
this excellent presentation *[Understanding Git][understanding-git]* from
|
||||||
|
Nelson Elhage and Anders Kaseorg and the [Git Basics][gitbook-basics] chapter
|
||||||
|
from *Pro Git* by Scott Chacon and Ben Straub.
|
||||||
|
|
||||||
|
Here are the top things to know:
|
||||||
|
|
||||||
|
- **Git works on snapshots:** Unlike other version control systems (e.g.,
|
||||||
|
Subversion, Perforce, Bazaar), which track files and changes to those files
|
||||||
|
made over time, Git tracks *snapshots* of your project. Each time you commit
|
||||||
|
or otherwise make a change to your repository, Git takes a snapshot of your
|
||||||
|
project and stores a reference to that snapshot. If a file hasn't changed,
|
||||||
|
Git creates a link to the identical file rather than storing it again.
|
||||||
|
|
||||||
|
- **Most Git operations are local:** Git is a distributed version control
|
||||||
|
system, so once you've cloned a repository, you have a complete copy of that
|
||||||
|
repository's *entire history*. Staging, committing, branching, and browsing
|
||||||
|
history are all things you can do locally without network access and without
|
||||||
|
immediately affecting any remote repositories. To make or receive changes
|
||||||
|
from remote repositories, you need to `git fetch`, `git pull`, or `git push`.
|
||||||
|
|
||||||
|
- **Nearly all Git actions add information to the Git database**, rather than
|
||||||
|
removing it. As such, it's hard to make Git perform actions that you can't
|
||||||
|
undo. However, Git can't undo what it doesn't know about, so it's a good
|
||||||
|
practice to frequently commit your changes and frequently push your commits to
|
||||||
|
your remote repository.
|
||||||
|
|
||||||
|
- **Git is designed for lightweight branching and merging.** Branches are
|
||||||
|
simply references to snapshots. It's okay and expected to make a lot of
|
||||||
|
branches, even throwaway and experimental ones.
|
||||||
|
|
||||||
|
- **Git stores all data as objects, of which there are four types:** blob
|
||||||
|
(file), tree (directory), commit (revision), and tag. Each of these objects
|
||||||
|
is named by a unique hash, the SHA-1 has of its contents. Most of the time
|
||||||
|
you'll refer to objects by their truncated hash or more human-readable
|
||||||
|
reference like `HEAD` (the current branch). Blobs and trees represent files
|
||||||
|
and directories. Tags are named references to other objects. A commit object
|
||||||
|
includes: tree id, zero or more parents as commit ids, an author (name,
|
||||||
|
email, date), a committer (name, email, date), and a log message. A Git
|
||||||
|
repository is a collection of mutable pointers to these objects called
|
||||||
|
**refs**.
|
||||||
|
|
||||||
|
- **Cloning a repository creates a working copy.** Every working copy has a
|
||||||
|
`.git` subdirectory, which contains its own Git repository. The `.git`
|
||||||
|
subdirectory also tracks the *index*, a staging area for changes that will
|
||||||
|
become part of the next commit. All files outside of `.git` is the *working
|
||||||
|
tree*.
|
||||||
|
|
||||||
|
- **Files tracked with Git have possible three states: committed, modified, and
|
||||||
|
staged.** Committed files are those safely stored in your local `.git`
|
||||||
|
repository/database. Staged files have changes and have been marked for
|
||||||
|
inclusion in the next commit; they are part of the index. Modified files have
|
||||||
|
changes but have not yet been marked for inclusion in the next commit; they
|
||||||
|
have not been added to the index.
|
||||||
|
|
||||||
|
- **Git commit workflow is as follows:** Edit files in your *working tree*. Add
|
||||||
|
to the *index* (that is *stage*) with `git add`. *Commit* to the HEAD of the
|
||||||
|
current branch with `git commit`.

# Get and stay out of trouble
|
||||||
|
|
||||||
|
Git is a powerful yet complex version control system. Even for contributors
|
||||||
|
experienced at using version control, it can be confusing. The good news is
|
||||||
|
that nearly all Git actions add information to the Git database, rather than
|
||||||
|
removing it. As such, it's hard to make Git perform actions that you can't
|
||||||
|
undo. However, git can't undo what it doesn't know about, so it's a good
|
||||||
|
practice to frequently commit your changes and frequently push your commits to
|
||||||
|
your remote repository.
|
||||||
|
|
||||||
|
## Undo a merge commit
|
||||||
|
|
||||||
|
A merge commit is a special type of commit that has two parent commits. It's
|
||||||
|
created by Git when you merge one branch into another and the last commit on
|
||||||
|
your current branch is not a direct ancestor of the branch you are trying to
|
||||||
|
merge in. This happens quite often in a busy project like Zulip where there are
|
||||||
|
many contributors because upstream/zulip will have new commits while you're
|
||||||
|
working on a feature or bugfix. In order for Git to merge your changes and the
|
||||||
|
changes that have occurred on zulip/upstream since you first started your work,
|
||||||
|
it must perform a three-way merge and create a merge commit.
|
||||||
|
|
||||||
|
Merge commits aren't bad, however, Zulip doesn't use them. Instead Zulip uses a
|
||||||
|
forked-repo, rebase-oriented workflow.
|
||||||
|
|
||||||
|
A merge commit is usually created when you've run `git pull` or `git merge`.
|
||||||
|
You'll know you're creating a merge commit if you're prompted for a commit
|
||||||
|
message and the default is something like this:
|
||||||
|
|
||||||
|
```
|
||||||
|
Merge branch 'master' of https://github.com/zulip/zulip
|
||||||
|
|
||||||
|
# Please enter a commit message to explain why this merge is necessary,
|
||||||
|
# especially if it merges an updated upstream into a topic branch.
|
||||||
|
#
|
||||||
|
# Lines starting with '#' will be ignored, and an empty message aborts
|
||||||
|
# the commit.
|
||||||
|
```
|
||||||
|
|
||||||
|
And the first entry for `git log` will show something like:
|
||||||
|
|
||||||
|
```
|
||||||
|
commit e5f8211a565a5a5448b93e98ed56415255546f94
|
||||||
|
Merge: 13bea0e e0c10ed
|
||||||
|
Author: Christie Koehler <ck@christi3k.net>
|
||||||
|
Date: Mon Oct 10 13:25:51 2016 -0700
|
||||||
|
|
||||||
|
Merge branch 'master' of https://github.com/zulip/zulip
|
||||||
|
```
|
||||||
|
|
||||||
|
Some graphical Git clients may also create merge commits.
|
||||||
|
|
||||||
|
To undo a merge commit, first run `git reflog` to identify the commit you want
|
||||||
|
to roll back to:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git reflog
|
||||||
|
|
||||||
|
e5f8211 HEAD@{0}: pull upstream master: Merge made by the 'recursive' strategy.
|
||||||
|
13bea0e HEAD@{1}: commit: test commit for docs.
|
||||||
|
```
|
||||||
|
|
||||||
|
Reflog output will be long. The most recent git refs will be listed at the top.
|
||||||
|
In the example above `e5f8211 HEAD@{0}:` is the merge commit made automatically
|
||||||
|
by `git pull` and `13bea0e HEAD@{1}:` is the last commit I made before running
|
||||||
|
`git pull`, the commit that I want to rollback to.
|
||||||
|
|
||||||
|
Once you'd identified the ref you want to revert to, you can do so with [git
|
||||||
|
reset][gitbook-reset]:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git reset --hard 13bea0e
|
||||||
|
HEAD is now at 13bea0e test commit for docs.
|
||||||
|
```
|
||||||
|
|
||||||
|
**Important:** `git reset --hard <commit>` will discard all changes in your
|
||||||
|
working directory and index since the commit you're resetting to with
|
||||||
|
*<commit>*. *This is the main way you can lose work in Git*. If you need to
|
||||||
|
keep any changes that are in your working directory or that you have committed,
|
||||||
|
use `git reset --merge <commit>` instead.
|
||||||
|
|
||||||
|
You can also use the relative reflog `HEAD@{1}` instead of the commit hash,
|
||||||
|
just keep in mind that this changes as you run git commands.
|
||||||
|
|
||||||
|
Now when you look at the output of `git reflog`, you should see that the tip of your branch points to your
|
||||||
|
last commit `13bea0e` before the merge:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git reflog
|
||||||
|
|
||||||
|
13bea0e HEAD@{2}: reset: moving to HEAD@{1}
|
||||||
|
e5f8211 HEAD@{3}: pull upstream master: Merge made by the 'recursive' strategy.
|
||||||
|
13bea0e HEAD@{4}: commit: test commit for docs.
|
||||||
|
```
|
||||||
|
|
||||||
|
And the first entry `git log` shows is this:
|
||||||
|
|
||||||
|
```
|
||||||
|
commit 13bea0e40197b1670e927a9eb05aaf50df9e8277
|
||||||
|
Author: Christie Koehler <ck@christi3k.net>
|
||||||
|
Date: Mon Oct 10 13:25:38 2016 -0700
|
||||||
|
|
||||||
|
test commit for docs.
|
||||||
|
```
|
||||||
|
|
||||||
|
## Restore a lost commit
|
||||||
|
|
||||||
|
We've mentioned you can use `git reset --hard` to rollback to a previous
|
||||||
|
commit. What if you run `git reset --hard` and then realize you actually need
|
||||||
|
one or more of the commits you just discarded? No problem, you can restore them
|
||||||
|
with `git cherry-pick` ([docs][gitbook-git-cherry-pick]).
|
||||||
|
|
||||||
|
For example, let's say you just committed "some work" and your `git log` looks
|
||||||
|
like this:
|
||||||
|
|
||||||
|
```
|
||||||
|
* 67aea58 (HEAD -> master) some work
|
||||||
|
* 13bea0e test commit for docs.
|
||||||
|
```
|
||||||
|
|
||||||
|
You then mistakenly run `git reset --hard 13bea0e`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git reset --hard 13bea0e
|
||||||
|
HEAD is now at 13bea0e test commit for docs.
|
||||||
|
|
||||||
|
$ git log
|
||||||
|
* 13bea0e (HEAD -> master) test commit for docs.
|
||||||
|
```
|
||||||
|
|
||||||
|
And then realize you actually needed to keep commit 67aea58. First, use `git
|
||||||
|
reflog` to confirm that commit you want to restore and then run `git
|
||||||
|
cherry-pick <commit>`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git reflog
|
||||||
|
13bea0e HEAD@{0}: reset: moving to 13bea0e
|
||||||
|
67aea58 HEAD@{1}: commit: some work
|
||||||
|
|
||||||
|
$ git cherry-pick 67aea58
|
||||||
|
[master 67aea58] some work
|
||||||
|
Date: Thu Oct 13 11:51:19 2016 -0700
|
||||||
|
1 file changed, 1 insertion(+)
|
||||||
|
create mode 100644 test4.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
## Recover from a git rebase failure
|
||||||
|
|
||||||
|
One situation in which `git rebase` will fail and require you to intervene is
|
||||||
|
when your change, which git will try to re-apply on top of new commits from
|
||||||
|
which ever branch you are rebasing on top of, is to code that has been changed
|
||||||
|
by those new commits.
|
||||||
|
|
||||||
|
For example, while I'm working on a file, another contributor makes a change to
|
||||||
|
that file, submits a pull request and has their code merged into master.
|
||||||
|
Usually this is not a problem, but in this case the other contributor made a
|
||||||
|
change to a part of the file I also want to change. When I try to bring my
|
||||||
|
branch up to date with `git fetch` and then `git rebase upstream/master`, I see
|
||||||
|
the following:
|
||||||
|
|
||||||
|
```
|
||||||
|
First, rewinding head to replay your work on top of it...
|
||||||
|
Applying: test change for docs
|

This message tells me that Git was not able to apply my changes to README.md
|

after bringing in the new commits from upstream/master.
|
||||||
|
|
||||||
|
Running `git status` also gives me some information:
|
||||||
|
|
||||||
|
```
|
||||||
|

|
||||||

You are currently rebasing branch 'docs-test' on '5ae56e6'.
|
||||||
|
(fix conflicts and then run "git rebase --continue")
|
||||||
|
(use "git rebase --skip" to skip this patch)
|
||||||
|
(use "git rebase --abort" to check out the original branch)
|
||||||
|
|
||||||
|
Unmerged paths:
|
||||||
|
(use "git reset HEAD <file>..." to unstage)

||||||
|
(use "git add <file>..." to mark resolution)
|

|
|
||||||
|
both modified: README.md
|
||||||
|
|
||||||
|
no changes added to commit (use "git add" and/or "git commit -a")
|
||||||
|
```
|
||||||
|
|
||||||
|
To fix, open all the files with conflicts in your editor and decide which edits
|
||||||
|
should be applied. Git uses standard conflict-resolution (`<<<<<<<`, `=======`,
|
||||||
|
and `>>>>>>>`) markers to indicate where in files there are conflicts.
|
||||||
|
|
||||||
|
Tip: You can see recent changes made to a file by running the following
|
||||||
|
commands:
|
||||||
|
```
|
||||||
|
git fetch upstream
|
||||||
|
git log -p upstream/master -- /path/to/file
|
||||||
|
```
|
||||||
|
You can use this to compare the changes that you have made to a file with the
|
||||||
|
ones in upstream, helping you avoid undoing changes from a previous commit when
|
||||||
|
you are rebasing.
|
||||||
|
|
||||||
|
Once you've done that, save the file(s), stage them with `git add` and then
|
||||||
|
continue the rebase with `git rebase --continue`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git add README.md
|
||||||
|
|
||||||
|
$ git rebase --continue
|
||||||
|
Applying: test change for docs
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|

|
||||||
|
|
||||||
|
## Working from multiple computers
|
||||||
|
|
||||||
|
Working from multiple computers with Zulip and Git is fine, but you'll need to
|
||||||
|
pay attention and do a bit of work to ensure all of your work is readily
|
||||||
|
available.
|
||||||
|
|
||||||
|
Recall that most Git operations are local. When you commit your changes with
|
||||||
|
`git commit` they are safely stored in your *local* Git database only. That is,
|
||||||
|
until you *push* the commits to GitHub, they are only available on the computer
|
||||||
|
where you committed them.
|
||||||
|
|
||||||
|
So, before you stop working for the day, or before you switch computers, push
|
||||||
|
all of your commits to GitHub with `git push`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git push origin <branchname>
|
||||||
|
```
|
||||||
|
|
||||||
|
When you first start working on a new computer, you'll [clone the Zulip
|
||||||
|
repository][clone-to-your-machine] and [connect it to Zulip
|
||||||
|
upstream][connect-upstream]. A clone retrieves all current commits,
|
||||||
|
including the ones you pushed to GitHub from your other computer.
|
||||||
|
|
||||||
|
But if you're switching to another computer on which you have already cloned
|
||||||
|
Zulip, you need to update your local Git database with new refs from your
|
||||||
|
GitHub fork. You do this with `git fetch`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git fetch <usermame>
|
||||||
|
```
|
||||||
|
|
||||||
|
Ideally you should do this before you have made any commits on the same branch
|
||||||
|
on the second computer. Then you can `git merge` on whichever branch you need
|
||||||
|
to update:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout <my-branch>
|
||||||
|
Switched to branch '<my-branch>'
|
||||||
|
|
||||||
|
$ git merge origin/master
|
||||||
|
```
|
||||||
|
|
||||||
|
**If you have already made commits on the second computer that you need to
|
||||||
|
keep,** you'll need to use `git log FETCH_HEAD` to identify that hashes of the
|
||||||
|
commits you want to keep and then `git cherry-pick <commit>` those commits into
|
||||||
|
whichever branch you need to update.

# Using Git as you work
|
||||||
|
|
||||||
|
## Know what branch you're working on
|
||||||
|
|
||||||
|
When using Git, it's important to know which branch you currently have checked
|
||||||
|
out because most git commands implicitly operate on the current branch. You can
|
||||||
|
determine the currently checked out branch several ways.
|
||||||
|
|
||||||
|
One way is with [git status][gitbook-git-status]:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git status
|
||||||
|
On branch issue-demo
|
||||||
|
nothing to commit, working directory clean
|
||||||
|
```
|
||||||
|
|
||||||
|
Another is with [git branch][gitbook-git-branch] which will display all local
|
||||||
|
branches, with a star next to the current branch:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git branch
|
||||||
|
* issue-demo
|
||||||
|
master
|
||||||
|
```
|
||||||
|
|
||||||
|
To see even more information about your branches, including remote branches,
|
||||||
|
use `git branch -vva`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git branch -vva
|
||||||
|
* issue-123 517468b troubleshooting tip about provisioning

||||||
|
remotes/upstream/master dbeab6a Optimize checks of test database state by moving into Python.
|
||||||
|
```
|
||||||
|
|
||||||
|
You can also configure [Bash][gitbook-other-envs-bash] and
|
||||||
|
[Zsh][gitbook-other-envs-zsh] to display the current branch in your prompt.
|
||||||
|
|
||||||
|
## Keep your fork up to date
|
||||||
|
|
||||||
|
You'll want to [keep your fork][github-help-sync-fork] up-to-date with changes
|
||||||
|
from Zulip's main repositories.
|
||||||
|
|
||||||
|
**Note about git pull**: You might be used to using `git pull` on other
|
||||||
|
projects. With Zulip, because we don't use merge commits, you'll want to avoid
|
||||||
|
it. Rather that using `git pull`, which by default is a shortcut for `git fetch
|
||||||
|
&& git merge FETCH_HEAD` ([docs][gitbook-git-pull]), you should use `git fetch`
|
||||||
|
and then `git rebase`.
|
||||||
|
|
||||||
|
First, [fetch][gitbook-fetch] changes from Zulip's upstream repository you
|
||||||
|
configured in the step above:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git fetch upstream
|
||||||
|
```
|
||||||
|
|
||||||
|
Next, checkout your `master` branch and [rebase][gitbook-git-rebase] it on top
|
||||||
|
of `upstream/master`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout master
|
||||||
|
Switched to branch 'master'
|
||||||
|
|
||||||
|
$ git rebase upstream/master
|
||||||
|
```
|
||||||
|
|
||||||
|
This will rollback any changes you've made to master, update it from
|
||||||
|
`upstream/master`, and then re-apply your changes. Rebasing keeps the commit
|
||||||
|
history clean and readable.
|
||||||
|
|
||||||
|
When you're ready, [push your changes][github-help-push] to your remote fork.
|
||||||
|
Make sure you're in branch `master` and the run `git push`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout master
|
||||||
|
$ git push origin master
|
||||||
|
```
|
||||||
|
|
||||||
|
You can keep any branch up to date using this method. If you're working on a
|
||||||
|
feature branch (see next section), which we recommend, you would change the
|
||||||
|
command slightly, using the name of your `feature-branch` rather than `master`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout feature-branch
|
||||||
|
Switched to branch 'feature-branch'
|
||||||
|
|
||||||
|
$ git rebase upstream/master
|
||||||
|
|
||||||
|
$ git push origin feature-branch
|
||||||
|
```
|
||||||
|
|
||||||
|
## Work on a feature branch
|
||||||
|
|
||||||
|
One way to keep your work organized is to create a branch for each issue or
|
||||||
|
feature. Recall from [how Git is different][how-git-is-different] that
|
||||||
|
**Git is designed for lightweight branching and merging.** You can and should
|
||||||
|
create as many branches as you'd like.
|
||||||
|
|
||||||
|
First, make sure your master branch is up-to-date with Zulip upstream ([see
|
||||||
|
how][zulip-git-guide-up-to-date]).
|
||||||
|
|
||||||
|
Next, from your master branch, create a new tracking branch, providing a
|
||||||
|
descriptive name for your feature branch:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout master
|
||||||
|
Switched to branch 'master'
|
||||||
|
|
||||||
|
$ git checkout -b issue-1755-fail2ban
|
||||||
|
Switched to a new branch 'issue-1755-fail2ban'
|
||||||
|
```
|
||||||
|
|
||||||
|
Alternatively, you can create a new branch explicitly based off
|
||||||
|
`upstream/master`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout -b issue-1755-fail2ban upstream/master
|
||||||
|
Switched to a new branch 'issue-1755-fail2ban'
|
||||||
|
```
|
||||||
|
|
||||||
|
Now you're ready to work on the issue or feature.
|
||||||
|
|
||||||
|
## Run linters and tests locally
|
||||||
|
|
||||||
|
In addition to having Travis run tests and linters each time you push a new
|
||||||
|
commit, you can also run them locally. See [testing](../testing/testing.html) for details.
|
||||||
|
|
||||||
|
## Stage changes
|
||||||
|
|
||||||
|
Recall that files tracked with Git have possible three states:
|
||||||
|
committed, modified, and staged.
|
||||||
|
|
||||||
|
To prepare a commit, first add the files with changes that you want
|
||||||
|
to include in your commit to your staging area. You *add* both new files and
|
||||||
|
existing ones. You can also remove files from staging when necessary.
|
||||||
|
|
||||||
|
### Get status of working directory
|
||||||
|
|
||||||
|
To see what files in the working directory have changes that have not been
|
||||||
|
staged, use `git status`.
|
||||||
|
|
||||||
|
If you have no changes in the working directory, you'll see something like
|
||||||
|
this:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git status
|
||||||
|
On branch issue-123
|
||||||
|
nothing to commit, working directory clean
|
||||||
|
```
|
||||||
|
|
||||||
|
If you have unstaged changes, you'll see something like this:
|
||||||
|
|
||||||
|
```
|
||||||
|
On branch issue-123
|
||||||
|
Untracked files:
|
||||||
|
(use "git add <file>..." to include in what will be committed)
|
||||||
|
|
||||||
|
newfile.py
|
||||||
|
|
||||||
|
nothing added to commit but untracked files present (use "git add" to track)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Stage additions with git add
|
||||||
|
|
||||||
|
To add changes to your staging area, use `git add <filename>`. Because `git
|
||||||
|
add` is all about staging the changes you want to commit, you use it to add
|
||||||
|
*new files* as well as *files with changes* to your staging area.
|
||||||
|
|
||||||
|
Continuing our example from above, after we run `git add newfile.py`, we'll see
|
||||||
|
the following from `git status`:
|
||||||
|
|
||||||
|
```
|
||||||
|
On branch issue-123
|
||||||
|
Changes to be committed:
|
||||||
|
(use "git reset HEAD <file>..." to unstage)
|
||||||
|
|
||||||
|
new file: newfile.py
|
||||||
|
```
|
||||||
|
|
||||||
|
You can view the changes in files you have staged with `git diff --cached`. To
|
||||||
|
view changes to files you haven't yet staged, just use `git diff`.
|
||||||
|
|
||||||
|
If you want to add all changes in the working directory, use `git add -A`
|
||||||
|
([documentation][gitbook-add]).
|
||||||
|
|
||||||
|
|
||||||
|
You can also stage changes using your graphical Git client.
|
||||||
|
|
||||||
|
If you stage a file, you can undo it with `git reset HEAD <filename>`. Here's
|
||||||
|
an example where we stage a file `test3.txt` and then unstage it:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git add test3.txt
|
||||||
|
On branch issue-1234
|
||||||
|
Changes to be committed:
|
||||||
|
(use "git reset HEAD <file>..." to unstage)
|
||||||
|
|
||||||
|
new file: test3.txt
|
||||||
|
|
||||||
|
$ git reset HEAD test3.txt
|
||||||
|
$ git status
|
||||||
|
On branch issue-1234
|
||||||
|
Untracked files:
|
||||||
|
(use "git add <file>..." to include in what will be committed)
|
||||||
|
|
||||||
|
test3.txt
|
||||||
|
|
||||||
|
nothing added to commit but untracked files present (use "git add" to track)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Stage deletions with git rm
|
||||||
|
|
||||||
|
To remove existing files from your repository, use `git rm`
|
||||||
|
([documentation][gitbook-rm]). This command can either stage the file for
|
||||||
|
removal from your repository AND delete it from your working directory or just
|
||||||
|
stage the file for deletion and leave it in your working directory.
|
||||||
|
|
||||||
|
To stage a file for deletion and **remove** it from your working directory, use
|
||||||
|
`git rm <filename>`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git rm test.txt
|
||||||
|
rm 'test.txt'
|
||||||
|
|
||||||
|
$ git status
|
||||||
|
On branch issue-1234
|
||||||
|
Changes to be committed:
|
||||||
|
(use "git reset HEAD <file>..." to unstage)
|
||||||
|
|
||||||
|
deleted: test.txt
|
||||||
|
|
||||||
|
$ ls test.txt
|
||||||
|
ls: No such file or directory
|
||||||
|
```
|
||||||
|
|
||||||
|
To stage a file for deletion and **keep** it in your working directory, use
|
||||||
|
`git rm --cached <filename>`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git rm --cached test2.txt
|
||||||
|
rm 'test2.txt'
|
||||||
|
|
||||||
|
$ git status
|
||||||
|
On branch issue-1234
|
||||||
|
Changes to be committed:
|
||||||
|
(use "git reset HEAD <file>..." to unstage)
|
||||||
|
|
||||||
|
deleted: test2.txt
|
||||||
|
|
||||||
|
$ ls test2.txt
|
||||||
|
test2.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
If you stage a file for deletion with the `--cached` option, and haven't yet
|
||||||
|
run `git commit`, you can undo it with `git reset HEAD <filename>`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git reset HEAD test2.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
Unfortunately, you can't restore a file deleted with `git rm` if you didn't use
|
||||||
|
the `--cache` option. However, `git rm` only deletes files it knows about.
|
||||||
|
Files you have never added to git won't be deleted.
|
||||||
|
|
||||||
|
## Commit changes
|
||||||
|
|
||||||
|
When you've staged all your changes, you're ready to commit. You can do this
|
||||||
|
with `git commit -m "My commit message."` to include a commit message.
|
||||||
|
|
||||||
|
Here's an example of committing with the `-m` for a one-line commit message:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git commit -m "Add a test commit for docs."
|
||||||
|
[issue-123 173e17a] Add a test commit for docs.
|
||||||
|
1 file changed, 1 insertion(+)
|
||||||
|
create mode 100644 newfile.py
|
||||||
|
```
|
||||||
|
|
||||||
|
You can also use `git commit` without the `-m` option and your editor to open,
|
||||||
|
allowing you to easily draft a multi-line commit message.
|
||||||
|
|
||||||
|
How long your commit message should be depends on where you are in your work.
|
||||||
|
Using short, one-line messages for commits related to in-progress work makes
|
||||||
|
sense. For a commit that you intend to be final or that encompasses a
|
||||||
|
significant amount or complex work, you should include a longer message.
|
||||||
|
|
||||||
|
Keep in mind that your commit should contain a 'minimal coherent idea' and have
|
||||||
|
a quality commit message. See Zulip docs [Commit
|
||||||
|
Discipline][zulip-rtd-commit-discipline] and [Commit
|
||||||
|
messages][zulip-rtd-commit-messages] for details.
|
||||||
|
|
||||||
|
Here's an example of a longer commit message that will be used for a pull request:
|
||||||
|
|
||||||
|
```
|
||||||
|
Integrate Fail2Ban.
|
||||||
|
|
||||||
|
Updates Zulip logging to put an unambiguous entry into the logs such
|
||||||
|
that fail2ban can be configured to look for these entries.
|
||||||
|
|
||||||
|
Tested on my local Ubuntu development server, but would appreciate
|
||||||
|
someone testing on a production install with more users.
|
||||||
|
|
||||||
|
Fixes #1755.
|
||||||
|
```
|
||||||
|
|
||||||
|
The first line is the summary. It's a complete sentence, ending in a period. It
|
||||||
|
uses a present-tense action verb, "Integrate", rather than "Integrates" or
|
||||||
|
"Integrating".
|
||||||
|
|
||||||
|
The following paragraphs are full prose and explain why and how the change was
|
||||||
|
made. It explains what testing was done and asks specifically for further
|
||||||
|
testing in a more production-like environment.
|
||||||
|
|
||||||
|
The final paragraph indicates that this commit addresses and fixes issue #1755.
|
||||||
|
When you submit your pull request, GitHub will detect and link this reference
|
||||||
|
to the appropriate issue. Once your commit is merged into zulip/master, GitHub
|
||||||
|
will automatically close the referenced issue. See [Closing issues via commit
|
||||||
|
messages][github-help-closing-issues] for details.
|
||||||
|
|
||||||
|
Make as many commits as you need to to address the issue or implement your feature.
|
||||||
|
|
||||||
|
## Push your commits to GitHub
|
||||||
|
|
||||||
|
As you're working, it's a good idea to frequently push your changes to GitHub.
|
||||||
|
This ensures your work is backed up should something happen to your local
|
||||||
|
machine and allows others to follow your progress. It also allows you to
|
||||||
|
[work from multiple computers][self-multiple-computers] without losing work.
|
||||||
|
|
||||||
|
Pushing to a feature branch is just like pushing to master:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git push origin <branch-name>
|
||||||
|
Counting objects: 6, done.
|
||||||
|
Delta compression using up to 4 threads.
|
||||||
|
Compressing objects: 100% (4/4), done.
|
||||||
|
Writing objects: 100% (6/6), 658 bytes | 0 bytes/s, done.
|
||||||
|
Total 6 (delta 3), reused 0 (delta 0)
|
||||||
|
remote: Resolving deltas: 100% (3/3), completed with 1 local objects.
|
||||||
|
To git@github.com:christi3k/zulip.git
|
||||||
|
* [new branch] issue-demo -> issue-demo
|
||||||
|
```
|
||||||
|
|
||||||
|
If you want to see what git will do without actually performing the push, add
|
||||||
|
the `-n` (dry-run) option: `git push -n origin <branch-name>`. If everything
|
||||||
|
looks good, re-run the push command without `-n`.
|
||||||
|
|
||||||
|
If the feature branch does not already exist on GitHub, it will be created when
|
||||||
|
you push and you'll see `* [new branch]` in the command output.
|
||||||
|
|
||||||
|
## Examine and tidy your commit history
|
||||||
|
|
||||||
|
Examining your commit history prior to submitting your pull request is a good
|
||||||
|
idea. Is it tidy such that each commit represents a minimally coherent idea
|
||||||
|
(see [commit discipline][zulip-rtd-commit-discipline])? Do your commit messages
|
||||||
|
follow [Zulip's style][zulip-rtd-commit-messages]? Will the person reviewing
|
||||||
|
your commit history be able to clearly understand your progression of work?
|
||||||
|
|
||||||
|
On the command line, you can use the `git log` command to display an easy to
|
||||||
|
read list of your commits:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git log --all --graph --oneline --decorate
|
||||||
|
|
||||||
|
* 4f8d75d (HEAD -> 1754-docs-add-git-workflow) docs: Add details about configuring Travis CI.
|
||||||
|
* bfb2433 (origin/1754-docs-add-git-workflow) docs: Add section for keeping fork up-to-date to Git Guide.
|
||||||
|
* 4fe10f8 docs: Add sections for creating and configuring fork to Git Guide.
|
||||||
|
* 985116b docs: Add graphic client recs to Git Guide.
|
||||||
|
* 3c40103 docs: Add stubs for remaining Git Guide sections.
|
||||||
|
* fc2c01e docs: Add git guide quickstart.
|
||||||
|
| * f0eaee6 (upstream/master) bug: Fix traceback in get_missed_message_token_from_address().
|
||||||
|
```
|
||||||
|
|
||||||
|
Alternatively, use your graphical client to view the history for your feature branch.
|
||||||
|
|
||||||
|
If you need to update any of your commits, you can do so with an interactive
|
||||||
|
[rebase][github-help-rebase]. Common reasons to use an interactive rebase
|
||||||
|
include:
|
||||||
|
|
||||||
|
- squashing several commits into fewer commits
|
||||||
|
- splitting a single commit into two or more
|
||||||
|
- rewriting one or more commit messages
|
||||||
|
|
||||||
|
There is ample documentation on how to rebase, so we won't go into details
|
||||||
|
here. We recommend starting with GitHub's help article on
|
||||||
|
[rebasing][github-help-rebase] and then consulting Git's documentation for
|
||||||
|
[git-rebase][gitbook-git-rebase] if you need more details.
|
||||||
|
|
||||||
|
If all you need to do is edit the commit message for your last commit, you can
|
||||||
|
do that with `git commit --amend`. See [Git Basics - Undoing
|
||||||
|
Things][gitbook-basics-undoing] for details on this and other useful commands.
|
||||||
|
|
||||||
|
## Force-push changes to GitHub after you've altered your history
|
||||||
|
|
||||||
|
Any time you alter history for commits you have already pushed to GitHub,
|
||||||
|
you'll need to prefix the name of your branch with a `+`. Without this, your
|
||||||
|
updates will be rejected with a message such as:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git push origin 1754-docs-add-git-workflow
|
||||||
|
To git@github.com:christi3k/zulip.git
|
||||||
|
! [rejected] 1754-docs-add-git-workflow -> 1754-docs-add-git-workflow (non-fast-forward)
|
||||||
|
error: failed to push some refs to 'git@github.com:christi3k/zulip.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.
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
Re-running the command with `+<branch>` allows the push to continue by
|
||||||
|
re-writing the history for the remote repository:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git push origin +1754-docs-add-git-workflow
|
||||||
|
Counting objects: 12, done.
|
||||||
|
Delta compression using up to 4 threads.
|
||||||
|

|
||||||
|
Writing objects: 100% (12/12), 3.71 KiB | 0 bytes/s, done.
|
||||||
|
Total 12 (delta 8), reused 0 (delta 0)
|
||||||
|
remote: Resolving deltas: 100% (8/8), completed with 2 local objects.

|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
This is perfectly okay to do on your own feature branches, especially if you're
|
||||||
|
the only one making changes to the branch. If others are working along with
|
||||||
|
you, they might run into complications when they retrieve your changes because
|
||||||
|
anyone who has based their changes off a branch you rebase will have to do a
|
||||||
|
complicated rebase.

# Zulip-specific tools
|
||||||
|
|
||||||
|
This section will document the zulip-specific git tools contributors will find helpful.
|
||||||
|
|
||||||
|
## Set up git repo script
|
||||||
|
|
||||||
|
In the `tools` directory of [zulip/zulip][github-zulip-zulip] you'll find a
|
||||||
|
bash script `setup-git-repo`. This script installs the Zulip pre-commit hook.
|
||||||
|
This hook will run each time you `git commit` to automatically run linters,
|
||||||
|
etc. The hook passes no matter the result of the linter, but you should still
|
||||||
|
pay attention to any notices or warnings it displays.
|
||||||
|
|
||||||
|
It's simple to use. Make sure you're in the clone of zulip and run the following:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ ./tools/setup-git-repo
|
||||||
|
```
|
||||||
|
|
||||||
|
The script doesn't produce any output if successful. To check that the hook has
|
||||||
|
been installed, print a directory listing for `.git/hooks` and you should see
|
||||||
|
something similar to:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ ls -l .git/hooks
|
||||||
|
pre-commit -> ../../tools/pre-commit
|
||||||
|
```
|
||||||
|
|
||||||
|
## Set up Travis CI integration
|
||||||
|
|
||||||
|
You might also wish to [configure your fork for use with Travis CI][zulip-git-guide-travisci].
|
||||||
|
|
||||||
|
## Reset to pull request
|
||||||
|
|
||||||
|
`tools/reset-to-pull-request` is a short-cut for [checking out a pull request
|
||||||
|
locally][zulip-git-guide-fetch-pr]. It works slightly differently from the method
|
||||||
|
described above in that it does not create a branch for the pull request
|
||||||
|
checkout.
|
||||||
|
|
||||||
|
**This tool checks for uncommitted changes, but it will move the
|
||||||
|
current branch using `git reset --hard`. Use with caution.**
|
||||||
|
|
||||||
|
First, make sure you are working in a branch you want to move (in this
|
||||||
|
example, we'll use the local `master` branch). Then run the script
|
||||||
|
with the ID number of the pull request as the first argument.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ git checkout master
|
||||||
|
Switched to branch 'master'
|
||||||
|
Your branch is up-to-date with 'origin/master'.
|
||||||
|
|
||||||
|
$ ./tools/reset-to-pull-request 1900
|
||||||
|
+ request_id=1900
|
||||||
|
+ git fetch upstream pull/1900/head
|
||||||
|
remote: Counting objects: 159, done.
|
||||||
|
remote: Compressing objects: 100% (17/17), done.
|
||||||
|
remote: Total 159 (delta 94), reused 91 (delta 91), pack-reused 51
|
||||||
|
Receiving objects: 100% (159/159), 55.57 KiB | 0 bytes/s, done.
|
||||||
|
Resolving deltas: 100% (113/113), completed with 54 local objects.
|
||||||
|
From https://github.com/zulip/zulip
|
||||||
|
* branch refs/pull/1900/head -> FETCH_HEAD
|
||||||
|
+ git reset --hard FETCH_HEAD
|
||||||
|
HEAD is now at 2bcd1d8 troubleshooting tip about provisioning
|
||||||
|
```
|
||||||
|
|
||||||
|
## Fetch a pull request and rebase
|
||||||
|
|
||||||
|
`tools/fetch-rebase-pull-request` is a short-cut for [checking out a pull
|
||||||
|
request locally][zulip-git-guide-fetch-pr] in its own branch and then updating it with any
|
||||||
|
changes from upstream/master with `git rebase`.
|
||||||
|
|
||||||
|
Run the script with the ID number of the pull request as the first argument.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ tools/fetch-rebase-pull-request 1913
|
||||||
|
+ request_id=1913
|
||||||
|
+ git fetch upstream pull/1913/head
|
||||||
|
remote: Counting objects: 4, done.
|
||||||
|
remote: Compressing objects: 100% (4/4), done.
|
||||||
|
remote: Total 4 (delta 0), reused 0 (delta 0), pack-reused 0
|
||||||
|
Unpacking objects: 100% (4/4), done.
|
||||||
|
From https://github.com/zulip/zulip
|
||||||
|
* branch refs/pull/1913/head -> FETCH_HEAD
|
||||||
|
+ git checkout upstream/master -b review-1913
|
||||||
|
Branch review-1913 set up to track remote branch master from upstream.
|
||||||
|
Switched to a new branch 'review-1913'
|
||||||
|
+ git reset --hard FETCH_HEAD
|
||||||
|
HEAD is now at 99aa2bf Add provision.py fails issue in common erros
|
||||||
|
+ git pull --rebase
|
||||||
|
Current branch review-1913 is up to date.
|
||||||
|
```
|
||||||
|
|
||||||
|
## Fetch a pull request without rebasing
|
||||||
|
|
||||||
|
`tools/fetch-pull-request` is a similar to `tools/fetch-rebase-pull-request`, but
|
||||||
|
it does not rebase the pull request against upstream/master, thereby getting
|
||||||
|
exactly the same repository state as the commit author had.
|
||||||
|
|
||||||
|
Run the script with the ID number of the pull request as the first argument.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ tools/fetch-pull-request 5156
|
||||||
|
+ git diff-index --quiet HEAD
|
||||||
|
+ request_id=5156
|
||||||
|
+ remote=upstream
|
||||||
|
+ git fetch upstream pull/5156/head
|
||||||
|
From https://github.com/zulip/zulip
|
||||||
|
* branch refs/pull/5156/head -> FETCH_HEAD
|
||||||
|
+ git checkout -B review-original-5156
|
||||||
|
Switched to a new branch 'review-original-5156'
|
||||||
|
+ git reset --hard FETCH_HEAD
|
||||||
|
HEAD is now at 5a1e982 tools: Update clean-branches to clean review branches.
|
||||||
|
```
|
||||||
|
|
||||||
|
## Delete unimportant branches
|
||||||
|
|
||||||
|
`tools/clean-branches` is a shell script that removes branches that are either:
|
||||||
|
|
||||||
|
1. Local branches that are ancestors of origin/master.
|
||||||
|
2. Branches in origin that are ancestors of origin/master and named like `$USER-*`.
|
||||||
|
3. Review branches created by `tools/fetch-rebase-pull-request` and `tools/fetch-pull-request`.
|
||||||
|
|
||||||
|
First, make sure you are working in branch `master`. Then run the script without any
|
||||||
|
arguments for default behavior. Since removing review branches can inadvertently remove any
|
||||||
|
feature branches whose names are like `review-*`, it is not done by default. To
|
||||||
|
use it, run `tools/clean-branches --reviews`.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ tools/clean-branches --reviews
|
||||||
|
Deleting local branch review-original-5156 (was 5a1e982)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Merge conflict on yarn.lock file
|
||||||
|
|
||||||
|
If there is a merge conflict on yarn.lock, yarn should be run to
|
||||||
|
regenerate the file. *Important* don't delete the yarn.lock file. Checkout the
|
||||||
|
latest one from origin/master so that yarn knows the previous asset versions.
|
||||||
|
|
||||||
|
Run the following commands
|
||||||
|
```
|
||||||
|
git checkout origin/master -- yarn.lock
|
||||||
|
yarn install
|
||||||
|
git add yarn.lock
|
||||||
|
git rebase --continue
|
||||||
|
```
