------------------------------------------------------------------------ | ||
|
||
## General Notes | ||
|
||
- The terminology we use is based on the | ||
[Integrator Workflow ](http://en.wikipedia.org/wiki/Integrator_workflow). | ||
|
||
- Use a branching workflow similar to the one described | ||
in the [progit gitbook](http://progit.org/book/ch3-4.html). | ||
|
||
- Keep your own "master" and "devel" branches in sync with the | ||
main repository's "master" and "devel" branches. Specifically, | ||
do not push your own commits directly to your "master" and | ||
"devel" branches. | ||
|
||
- Any commit should *pass all tests* (see [Running Tests](#running-tests)). | ||
|
||
- See the [An Example](#an-example) section below for a full walk through. | ||
|
||
- In addition to a review of the algorithmic and logical changes in | ||
your contribution, it will be reviewed on a variety of levels | ||
including such things as style, documentation, tests, etc. While | ||
such review can appear tedious, these aspects are important for the | ||
long term success of the project. | ||
|
||
## Issuing a Pull Request | ||
|
||
- When you are ready to move changes from one of your topic branches | ||
into the "devel" branch, it must be reviewed and accepted by | ||
another develer. | ||
|
||
- You may want to review this | ||
[tutorial](https://help.github.com/articles/using-pull-requests/) | ||
before you make a pull request to the devel branch. | ||
|
||
## Reviewing a Pull Request | ||
|
||
- Look over the code. | ||
|
||
- Check that it meets the [MOOSE style guidelines](http://mooseframework.org/wiki/CodeStandards/). | ||
|
||
- Make inline review comments concerning improvements. | ||
|
||
- Wait for the Continuous Integration service to show full test | ||
passage. | ||
|
||
- Click the green "Merge Pull Request" button. | ||
|
||
- Note: if the button is not available, the requester needs to merge | ||
or rebase from the current HEAD of the blessed's "devel" | ||
(or "master") branch. | ||
|
||
## Running Tests | ||
|
||
You can run the tests yourself using: - for Moltres: | ||
To ensure that Moltres is functioning properly, run the following from the | ||
root of the Moltres directory. | ||
|
||
```bash | ||
./run_tests -j8 | ||
``` | ||
|
||
## Cautions | ||
|
||
- **NEVER** merge the "master" branch into the "devel" branch. | ||
Changes should only flow *to* the "master" branch *from* the | ||
"devel" branch. | ||
|
||
## An Example | ||
|
||
### Introduction | ||
|
||
As this type of workflow can be complicated to converts from SVN and | ||
very complicated for brand new programmers, an example is provided. | ||
|
||
For the sake of simplicity, let us assume that we want a single | ||
"sandbox" branch in which we would like to work, i.e. where we can store | ||
all of our work that may not yet pass tests or even compile, but where | ||
we also want to save our progress. Let us call this branch "Work". So, | ||
when all is said and done, in our fork there will be three branches: | ||
"master", "devel", and "Work". | ||
|
||
### Acquiring Moltres and Workflow | ||
|
||
We begin with a fork of the main Moltres repository. After initially forking the | ||
repo, we will have two branches in our fork: "master" and "devel". | ||
|
||
#### Acquiring a Fork of the Moltres Repository | ||
|
||
A fork is *your* copy of Moltres. Github offers an excellent | ||
[tutorial](http://help.github.com/fork-a-repo/) on how to set one up. | ||
The rest of this example assumes you have set up the "upstream" | ||
repository as `moltres/core`. Note that git refers to your fork as | ||
"origin". | ||
|
||
First, let's make our "work" branch: :: .../moltres\_dir/\$ git branch | ||
work .../moltres\_dir/\$ git push origin work | ||
|
||
We now have the following situation: | ||
|
||
- there exists the main copy of the master and devel branches, | ||
- there exists your fork's copy of the master, devel, and Work branches, | ||
-*AND* there exists your *local* copy of the master, devel, and Work branches. | ||
|
||
It is important now to note that you may wish to work from home or the office. | ||
If you keep your fork's branches up to date (i.e., "push" your changes before | ||
you leave), only your *local* copies of your branches may be different when you | ||
next sit down at the other location. | ||
|
||
#### Workflow: The Beginning | ||
|
||
Now, for the workflow! This is by no means the only way to perform this | ||
type of workflow, but I assume that you wish to handle conflicts as | ||
often as possible (so as to keep their total number small). Let us | ||
imagine that you have been at work, finished, and successfully pushed | ||
your changes to your *origin* repository. You are now at home and want | ||
to continue working a bit. To begin, let's update our *home's local | ||
branches*. :: | ||
|
||
``` | ||
.../moltres_dir/$ git checkout devel | ||
.../moltres_dir/$ git pull upstream devel | ||
.../moltres_dir/$ git push origin devel | ||
.../moltres_dir/$ git checkout work | ||
.../moltres_dir/$ git pull origin work | ||
.../moltres_dir/$ git rebase devel | ||
.../moltres_dir/$ git push origin work | ||
``` | ||
|
||
Perhaps a little explanation is required. We first want to make sure | ||
that this new local copy of the devel branch is up-to-date with | ||
respect to the remote origin's branch and remote upstream's branch. If | ||
there was a change from the remote upstream's branch, we want to push | ||
that to origin. We then follow the same process to update the work | ||
branch, except: | ||
|
||
1. we don't need to worry about the *upstream* repo because it doesn't | ||
have a work branch, and | ||
2. we want to incorporate any changes which may have been introduced in | ||
the devel branch update. | ||
|
||
#### Workflow: The End | ||
|
||
As time passes, you make some changes to files, and you commit those | ||
changes (to your *local work branch*). Eventually (hopefully) you come | ||
to a stopping point where you have finished your project on your work | ||
branch *AND* it compiles *AND* it runs input files correctly *AND* it | ||
passes all tests! Perhaps you have found Nirvana. In any case, you've | ||
performed the final commit to your work branch, so it's time to make a | ||
pull request online and wait for our develer friends to review and | ||
accept it. | ||
|
||
Sometimes, your pull request will be held by the reviewer until further | ||
changes are made to appease the reviewer's concerns. This may be | ||
frustrating, but please act rationally, discuss the issues on the GitHub | ||
space made for your pull request, consult the | ||
[style guide](http://moltres.github.com/devdoc/style_guide.html), | ||
email the develer listhost for further advice, and make changes to | ||
your topic branch accordingly. The pull request will be updated with | ||
those changes when you push them to your fork. When you think your | ||
request is ready for another review, you can reopen the review yourself | ||
with the button made available to you. | ||
