An effective RBTools workflow for Git

January 26, 2015April 2, 2020 Christian Hammond 4 Comments

Update: We’ve documented this workflow in the RBTools documentation. The following still applies, but for more details and tips, see the docs.

One of the beautiful things about Git is that you have so many ways of making it work for you. This is also one of the frightening things about Git, particularly if you’re just starting out. There’s loads of documentation and blog posts covering all the ways you can use Git to manage your code or shoot yourself in the foot.

A question we’re often asked is how Git is supposed to be used with Review Board or RBCommons.

“How should I post changes,” they ask. “How should I land them?”

“Well,” we say, “that’s up to you… but here’s how we do it.”

One branch per review request

Branches in Git are pretty great. They’re light-weight, and you can really choose when and how to use them.

What we like to do is have one branch for every review request we’re still working with. Maybe they’re branching off of master, or maybe off of another change you have up for review… doesn’t matter.

Create the branch, and create as many commits on it as you want. You’re going to post these all for review under one review request. For our example, we’ll use 2 commits.

$ git checkout -b my-branch-1 master
$ vim foo.py
$ git commit -a
$ vim bar.py
$ git commit -a

Now let’s create another branch off of that, and make one commit here. This will be for your second review request.

$ git checkout -b my-branch-2
$ vim foo.py
$ git commit -a

Your tree now looks like this:

o [my-branch-2]
|
o [my-branch-1]
|
o
|
o [master] [origin/master]
|

Great, let’s post!

We’ll post that first change for review (my-branch-1). Since it’s based off of origin/master, this will be easy (since by default, that’s what’s diffed against). We just post like so:

$ git checkout my-branch-1
$ rbt post
Review request #1001 posted.

https://reviewboard.example.com/r/1001/
https://reviewboard.example.com/r/1001/diff/

Excellent. If you go to that first URL, you’ll see your summary and description filled in from your commit messages. You can edit these to your liking.

If your server has any default reviewers set up, they’ll be assigned. You might also want to fill in some bug, add some testing information. Do whatever you want to do there and publish the review request.

Now sit back and relax and… oh wait, you have a second change ready for review! Thanks to Git and RBTools, you don’t have to wait on that. Let’s post that one too.

$ rbt post my-branch-1..my-branch-2
Review request #1002 posted.

https://reviewboard.example.com/r/1002/
https://reviewboard.example.com/r/1002/diff/

What you’re doing here is posting all the commits on my-branch-2 that were made since my-branch-1. No need to push my-branch-1 first, or really worry about it in any way.

You’ll probably want to set the Depends On field to point to your other review request, as a hint to any reviewers deciding which to review first.

Oh, here’s some short-hand. If you’re already on my-branch-2, you can make use of HEAD instead of spelling out my-branch-2. In this case, this branch only has one commit, so you could also leave out my-branch1... All of these are therefore equivalent:

$ rbt post HEAD
$ rbt post my-branch-1..HEAD
$ rbt post my-branch-1..my-branch-2

This is probably familiar to you if you’re used to Git. You can use any Git SHA/tag/branch/revision range you want when calling rbt post.

Note: If you’re posting against a remote branch other than origin/master, you’ll need to either pass --tracking-branch=myremote/mybranch on any RBTools command, or set TRACKING_BRANCH = "myremote/mybranch" in .reviewboardrc. The remote must match the configured repository on Review Board.

Need to make some changes? -u to the rescue!

So someone found a flaw in your otherwise perfect code. Happens to the best of us. In both review requests, you say? Okay, we’ll let that slide for now.

Let’s update the first change. Lots of options here. You can make a new commit with the fixes, or you can amend the commit.

If it’s just a fix made in a previously un-pushed commit, we like to amend. Your choice.

$ git checkout my-branch-1
$ vim bar.py
$ git commit -a --amend
$ rbt post -u
Review request #1001 posted.

https://reviewboard.example.com/r/1001/
https://reviewboard.example.com/r/1001/diff/

Now on to the second. We’ll probably want the latest from my-branch-1 as well, so we can rebase or merge. We like to rebase when this stuff is still in flux and not yet pushed, and we like to merge when the history starts to matter (that is, when the code is in some kind of decent, landable shape).

Again, your call.

$ git checkout my-branch-2
$ git rebase my-branch-1
$ vim foo.py
$ git commit -a --amend
$ rbt post -u HEAD
Review request #1002 posted.

https://reviewboard.example.com/r/1002/
https://reviewboard.example.com/r/1002/diff/

The -u flag updates an existing review request that matches your commit message. If you’ve modified the summary or description in any way, it may prompt you for any review requests that mostly match. Just say yes or no.

Great, publish those changes. Eventually the code will be perfect.

Got your “Ship It!”? Time to land!

RBTools 0.7 and higher comes with a nifty little command, rbt land. This command takes a branch, verifies that it’s been reviewed, and lands the changes.

Let’s land both of your branches, one after the other.

$ git checkout master
$ rbt land --dest=master --push my-branch-1
$ rbt land --dest=master --push my-branch-2

This will verify that my-branch-1 is approved (at least one “Ship It!” and no open issues). It will then merge my-branch-1 into master, push it, and delete the old branch. Then it’ll verify, merge, push, and delete my-branch-2.

Each branch you land will be merged into master, with a merge commit containing the summary, description, bug numbers, and review request URL. If you want to instead squash each branch into a single commit on master, you can use --squash.

You can use --dry-run to see what will happen without actually changing your tree. Useful when you first start off.

You can also edit the commit message using --edit, or leave out --push if you don’t want to push the branch, or add --no-delete-branch if you don’t want to delete the branches. You can also set the default branch to land into. The documentation goes into all the options that are available.

Closing out landed review requests

We like to set up our review requests to auto-close when pushing commits. This is designed to work with rbt land.

When you land a change, the commit message will contain a line saying something like:

Reviewed at https://reviewboard.example.com/r/1001/

The auto-close hooks will see that and automatically close your review request, so you don’t have to.

And that’s how we do it.

There’s really a lot of options here. Some people push changes and then use the web UI to post them for review. Some people generate their own diffs and upload them. Some like to merge their own branches.

That’s all a lot of work, though. Our method give us:

Nice code organization, since every review request has its own dedicated branch.
Fast posting and updating of review requests.
Less mess. No extra branches sticking around, and review requests are automatically closed.
Confidence that every landed change has been approved. No slip-ups with pushing the wrong branch.

Give it a try!

Composing workflows using aliases in RBTools

January 19, 2015January 19, 2015 Christian Hammond

RBTools 0.7 introduced support for aliases, a handy way to simplify common tasks and workflows when working with source code and review requests.

With aliases, you can write your own RBTools commands that expand into, well, anything. They could be a set of common options for an existing command, or they could call out to shell commands.

You can define your own aliases for your personal use, but you can also define aliases for your entire team. Since they live in .reviewboardrc, aliases can be committed to your repository for everyone to use. This is quite powerful, as it can help to easily standardize workflows for your whole team.

I’m going to show you a few ways to compose workflows using aliases.

Simplify posting code for review

Feature branches in Git are great. They help you to stay organized when you have lots of changes that depend on each other. If you’ve made heavy use of them, you’ve probably used this workflow a bit:

# Post some code...
$ rbt post HEAD

# After making some changes to code...
$ rbt post -u HEAD

# After making some changes to the commit message...
$ rbt post -g yes -u HEAD

There aren’t a lot of parameters there, but you still have to remember them and type them every time. The -u HEAD or the -g yes -u HEAD gets repetitive.

Let’s add a few nice and short aliases in ~/.reviewboardrc:

ALIASES = {
    # Post this
    'pt': 'post HEAD',

    # Post this and update
    'ptu': 'post -u HEAD',

    # Post this, update, and re-guess the description from the commit message
    'ptug': 'post -g yes -u HEAD',
}

Now the workflow becomes simply:

# Post some code...
$ rbt pt

# After making some changes to code...
$ rbt ptu

# After making some changes to the commit message...
$ rbt ptug

Much shorter, and hopefully easier to remember.

Run unit tests before posting code

If your project has a unit test suite, you’re probably supposed to run it before posting code for review. It’s easy to forget, or to just ignore it, since it’s another step in your process. We can solve both of those problems.

Say your project has a ./scripts/run-tests.sh that runs your test suite and outputs 1 for failure, 0 for success. Let’s make an alias that ensures tests pass before posting, and we’ll even pre-populate the Testing Done field with a message stating they pass. Let’s call this p for short.

ALIASES = {
    'p': '!./scripts/run-tests.sh &&'
         'rbt post --testing-done="Unit tests pass." $*',
}

Now you’ll never forget to run tests, and you’ll even have less to type.

ProTip: Define this as an alias in the .reviewboardrc in your repository, and switch your team to use that instead of rbt post.

Sanity-check patches on a review request

If you’re the gatekeeper for your project’s code (perhaps you’re an open source developer?), you need to test the patches that other people write before landing them. Thanks to rbt patch, you can easily pull down a diff from a review request and apply it, but you still need to run your tests before landing it. You also need to be careful not to disturb any changes in your own tree, or to test on the wrong branch.

To really sandbox your testing, your ideal workflow may look something like this:

$ git clone -b master . /tmp/test-project-<review request id>
$ cd /tmp/test-project-<review request id>
$ rbt patch <review request id>
$ ./scripts/runtests.sh
$ cd -
$ rm -rf /tmp/test-project-<reviw request id>

Let’s make an alias for this:

ALIASES = {
    'test-patch': '!rm -rf /tmp/test-project-$1 &&'
                  'git clone -b master . /tmp/test-project-$1 &&'
                  'cd /tmp/test-project-$1 &&'
                  'rbt patch $1 &&'
                  './scripts/runtests.sh &&'
                  'rm -rf /tmp/test-project-$1',
}

Now you have a quick and easy way to check any patch applying to the repository you’re currently in, without messing up your repository, typing a bunch of commands, or worrying about directories.

Screenshot a window and attach it in one go

If you’re doing UI work, you’re posting screenshots a lot. This means taking a screenshot, saving it somewhere, and drag-and-dropping it into a review request with a caption.

Let’s get that down to one command.

Now, different operating systems have different tools for capturing a screenshot. I’ll show an example for MacOS X and another for Linux. For Windows, you’ll need to grab a command line screenshot tool.

ALIASES = {
    # For MacOS X:
    'attach-screenshot': '!screencapture -wo /tmp/screenshot.png &&'
                         'rbt attach --caption "$2" $1 /tmp/screenshot.png &&'
                         'rm /tmp/screenshot.png',

    # For Linux:
    'attach-screenshot': '!import /tmp/screenshot.png &&'
                         'rbt attach $* tmp/screenshot.png &&'
                         'rm /tmp/screenshot.png',
}

Now uploading a screenshot is quick and easy! To upload to review request #123, just run:

$ rbt attach-screenshot 123

You can even attach a caption or custom filename, like so:

$ rbt attach-screenshot --caption="About dialog" --filename=about-dlg.png 123

Share your workflows!

We’d love to hear about any workflows you come up with. Send them along. We may even feature them in a future post or as samples in the documentation!

RBTools 0.7 is here!

January 18, 2015 Christian Hammond

RBTools 0.7 is packed with new tools and improvements for your workflow, making it faster to install, post changes to RBCommons, and land your changes.

There’s a lot here, so we’ll go into the major new additions.

Easy installation for Windows and MacOS X

We’ve improved the installation experience. If you’re on Windows or MacOS X, you can simply download the RBTools installer for your platform. In seconds, you’ll be ready to use the latest RBTools.

Land reviewed changes with one command

The all-new rbt land is the fastest way to take a change (in a local branch or a review request), validate that it’s been reviewed, and land it in your repository. It will format the commit message to include the review request’s description and testing information, and can even handle pushing the change upstream and deleting the local branch in one go.

(This is currently only available for Git repositories. Support for other repositories will come soon.)

Exclude files from review

Sometimes you’ll have modified files that you just don’t want up for review. Auto-generated code, for instance. You can now exclude these when posting changes for review by using the new -X option to rbt post, or by setting EXCLUDE_PATTERNS in .reviewboardrc.

Make your own commands with aliases

Ever find yourself repeating a group of options? rbt post -g yes -u HEAD, for instance? In 0.7, you can create an alias — a new RBTools command, basically — for those options.

You can even go a step further and make an alias that runs non-RBTools commands. Want to always run unit tests before posting code? Make an alias. How about merging the latest upstream changes into your branch before posting? There’s another alias!

See the documentation on aliases for more information.

Faster communication with RBCommons

We’ve sped up RBTools by caching results from RBCommons. This means lots of operations, such as posting changes, is faster than ever.

If you’re using the RBTools Python API to write your own integrations, you’ll benefit from this with no additional work on your end.

And lots more!

We haven’t even talked about rbt stamp, support for API tokens, or all the bug fixes and other feature improvements.

Check out the release notes for the whole list of changes.

Auto-close review requests when pushing commits

January 5, 2015December 28, 2017 Christian Hammond 1 Comment

Happy new year, everyone! Hope your holidays were fun and relaxing, with great company and wonderful memories. Mine certainly was, and now I’m back with some more tips and tricks to help you get the most out of Review Board and RBCommons.

Last time, we discussed some tips for getting the most out of your Review Board dashboard. This time, let’s talk about how to keep your dashboard clean by automatically closing review requests when pushing changes.

Introducing the post-commit hook

Post-commit hooks are a feature supported by many types of repositories and code hosting services. They allow you to execute custom code when pushing a commit, which is useful for kicking off a build, updating a website, or, in our case, closing a review request.

For self-hosted repositories, this is usually a script that you drop in a directory. This script can talk to Review Board through the RBTools API.

For repositories hosted on services like GitHub or Bitbucket these are often set up as URLs that the service can POST to. Review Board 2.0+ have some convenient URLs just for this purpose. We’ll talk about these first.

Configuring auto-close for GitHub and Bitbucket

If you’re running Review Board 2.0.7 or higher, we’ve made it very easy to get set up. Simply log into your administration UI and click Repositories. You should see a [Hooks] link beside any GitHub or Bitbucket repositories. Click it, and you’ll get exact instructions on how to get set up.

Do this for every repository you care about. Then, whenever you’re going to push a commit, make sure it has this line in the commit message:

Reviewed at <review request url>

Where, of course, the <review request url> is the full URL to the review request page. The hook will see that line, and close the matching review request for you, complete with information on the commit ID and the branch it landed on.

The upcoming RBTools 0.7 release will make it very easy to include this automatically with a couple new commands. We’ll cover these in a new post once that release is out.

One important caveat: These services need to be able to talk to your server. That means if you’re behind a firewall, you must grant access to these services and forward a port. If you’re on RBCommons, this won’t be a problem, though. And if you’re a GitHub user, look into using GitHub Enterprise with Power Pack for Review Board for a much more secure code hosting solution.

Configuring auto-close for custom Git repositories

Custom repositories are a bit trickier, because you need a custom script for your setup.

If you’re running Git, we have a script just for you! All you have to do is fill in some of the details in the script, rename it to post-receive, and drop it into your official Git repository’s hooks directory.

Not running Git? Unfortunately, there’s some work you’ll need to do for now. We’re working on some new scripts for Subversion and Mercurial, but if you feel up to it, you can put together your own post-commit hook, based on ours. All the communication is taken care of for you by RBTools.

Speaking of RBTools

We’re gearing up for a major RBTools release, with the goal of shipping it this week. If all goes according to plan, we’ll be back next week with an overview of the new features, and how they’ll help you get your code posted and landed faster than ever.

A new batch of feature and performance improvements

January 3, 2015December 28, 2017 Christian Hammond

Tonight, we’ve released a huge set of bug fixes and feature improvements for RBCommons that should improve your code review experience.

Faster performance

We’ve fine-tuned many parts of RBCommons to give you a faster experience.

Editing Markdown text should now feel as fast as editing plain text. The lag that would sometimes appear has been fixed.

The dashboard now loads a lot faster when using the People, Groups, or To Me columns.

We’ve also improved performance in our API. RBTools and various operations on the site should be much faster now.

Markdown improvements

Markdown is now completely optional. By default, all text fields on review requests and comments on reviews will be in Markdown mode, as before. However, you’ll now be able to turn off Markdown while editing, saving as plain text.

You can also choose to disable Markdown by default for all fields in your My Account page. Simply uncheck “Always use Markdown for text fields.”

Note that if Markdown is enabled by default, then all fields will start off editing in Markdown mode. Any plain text will be escaped first.

Along with this, we’ve fixed a number of escaping and rendering problems with Markdown text, particularly for text coming from a commit.

Better clipboard support in the diff viewer

The diff viewer now supports selecting and copying the text within either column in the diff viewer, without that selection covering code from the other column.

Previously, selecting worked like it did for any table in a web page, in that the selection would span both columns, making it impossible to get the text out cleanly. With this new support, you can safely copy a block of text from the original or modified file and paste it into your editor.

Better e-mail control

We’ve reduced how much e-mail you’ll receive in certain cases. For instance, if a review request is updated to add new reviewers, without altering any other fields or introducing a new diff, only the new reviewers will be notified of the update.

We’ve also introduced an option to let you opt out of any e-mails triggered by your own actions. To opt out, head over to the My Account page and uncheck “Get e-mail notifications for my own activity.”

Numerous bug fixes

We’ve fixed nearly 40 bugs across the site, covering issues with repository compatibility, diff generation, usability, e-mail notifications, and more.

4 powerful tips for your Review Board dashboard

December 22, 2014December 22, 2014 Christian Hammond 2 Comments

The dashboard. It’s the very first thing you’ll typically see when you log into Review Board. Outside of review requests and the diff viewer, you’ll spend most of your time here – but are you getting the most out of it?

Did you know that you could close several review requests at once? Or see which review requests were specifically assigned to you, or the number of lines added/removed in each diff, or the bugs addressed, all at a glance? How about being able to keep track of activity on groups you’re not a part of?

Let’s go through some of the ways you can make the dashboard work better for you.

1. Choosing what information to display

Take a look at the top-right of the dashboard, at the very last column. See that pencil icon? If you click it, you’re going to see a list of all the columns you can put on your dashboard. You can turn some on, turn others off.

Depending on how old your account is, you may be using an older default set of columns, meaning you’re really missing out on some handy columns.

Here are my favorites:

Diff Size, newly introduced in 2.0 and on RBCommons, takes the latest diff on the review request and shows the number of lines added and removed. This gives me a good idea as to how long a review may take.
My Comments is a default now, but it wasn’t always. This displays a handy icon showing if you’ve already reviewed a change, if that review is still a pending draft, and whether you’ve said Ship It! Super helpful for sorting through your workload.
Select Rows, also introduced in 2.0 and on RBCommons, adds a little checkbox for selecting review requests. Selecting one or more lets you perform actions, which we’ll go into below.
Ship It! is your way of knowing if reviewers have deemed a change ready to ship, or if there’s any issues to resolve (on 2.0+ and on RBCommons). Green checkmark for Ship It, and yellow exclamation point for issues to resolve. If you don’t have this column, add it now!
Starred lets you click to star/unstar a review request. Starring is a way to keep tabs on the activity on a review request you’re not assigned to, CCing you on all e-mails and making the review request quick to find in the dashboard.
To Me simply displays a little indicator (») for any review request directly assigned to you. Usually a good place to start when deciding what to review.

Here’s how my dashboard looks:

2. Reorder your columns

Okay, now you have some new columns, and they’re all shoved to the right of the dashboard. That’s probably not where you want them. That’s okay, we can fix that.

You can re-order columns by simply clicking and dragging the column header. Move it where you want it, and the dashboard will remember.

Reordering Columns

I like placing all the little icons (Starred, My Updates, Ship It!, My Comments, and To Me) toward the left, right before the summary. Play around, see what works for you. Go nuts.

3. Sort your columns

You now have a lovely set of columns exactly where you want them. There’s some timestamps in there, maybe the repository or branch names. Now’s a good time to learn about sorting.

Certain columns can sort their data. Most anything with text, like Summary, Branch, or Last Updated, can be sorted. When you click a column, it’ll sort in ascending order. Click again to sort in descending. Click the “X” to unsort that column.

Sorting Columns

There are two levels of sorting. Click a second column, and everything will be sorted by that. If two rows have the same data for that column, then they’ll be sorted by the previously clicked column.

To prioritize changes going into a release, click Last Updated and then Branch. You’ll quickly be able to see review requests grouped by branch, then sorted by when they were last updated.

4. Close many review requests at once

Is your dashboard getting a bit messy? Did you forget to close a bunch of old review requests, and just hate the thought of going through and dealing with them one-by-one? Or maybe you’re an administrator and someone just left the company with a mess to deal with.

Remember that Select Rows column from before? It gives you a nice little checkbox for each review request. When you start clicking those checkboxes, the dashboard’s sidebar will begin to give you a summary of the review requests, along with options to close them all at once. You can discard them, or mark them as submitted into the codebase.

Dashboard batch operations

In one go, you can clear away dozens of review requests, making everyone else on the team very thankful, and completely in your debt.

Speaking of…

Next time, we’re going to talk about how to keep your dashboard squeaky clean, without micromanaging review requests. You’ll learn how you can put an end to messy dashboards once and for all.

In the meantime, Happy Holidays everyone!

Review everything, not just code

December 15, 2014December 28, 2017 Christian Hammond

Code review is a staple in many engineering cultures. The benefits to putting your code up for your teammates to scrutinize and critique are numerous. There’s the satisfaction of showing off your work to your peers and the comfort in knowing that any obvious flaws or bad design choices will be caught before they affect others.

Unfortunately, code review is often where thorough review ends for many teams. UI changes, mockups, PRDs, documentation, release notes, icons, and other visual components critical to a project are not always as closely inspected, or at least are not done so as part of the existing code review process. By leaving these out, or doing them out-of-band (e-mail, in-person reviews), or even by going through entirely separate tools, there’s the risk of missing and tracking valuable feedback.

Through Review Board and Power Pack, you can review those just as easily as code. No new tools to learn, no loosely tracked discussions. Here’s how.

File attachments on Review Board

In Review Board, you can attach any type of file to a review request and review.

There’s built-in support for general text-based file attachments, Markdown files, and images. Extensions can supplement that with support for reviewing additional file types, like PDF. Unsupported binary files can still be reviewed by downloading the file and then leaving a comment on it.

All you need to do to attach files is to drag them (as many or as few as you want) from your file manager right onto any new or existing review request.

Or, if you’re a command line junkie like I am, check out tip #3 on our 5 tips for RBTools.

You’ll be able to try these yourself on our demo page.

Reviewing screenshots, icons, and other images

If you’re developing a UI for your application, make sure your fellow engineers or your usability team sees it before your QA team or users do.

Take a screenshot, or two, or a dozen. Show off all the changes you made, the new dialogs, the icon updates. Upload them as part of your code change so that your reviewers can see the impact of your code. Your reviewers will then be able to go through your screenshots and review them just like source code.

Reviewing images is easy. Simply click-and-drag over an area of the image, like you’re selecting it. A comment window will pop up (just like for code). Enter some text and save it. When the review is published, you’ll see that section of the image in the review, and discussion can begin.

Reviewing plain text files

As developers, we love plain text. We have one-off bits of test code not fit for the tree, we have log files, development notes, test runs. All kinds of things that your reviewers may find useful when looking at your code.

So post them.

Reviewers will see a nice display of the text similar to what they’d see in the diff viewer. If Review Board recognizes the file type, it’ll even syntax highlight it for you, which is great for files like XML.

Reviewing Markdown files

Markdown is a pretty popular way to write rich, formatted text in the comfort of your 1970s text editor. I’m using it right now to write this post, in fact, and you may be using it for your documentation or Wiki pages.

During review, we automatically render your Markdown so that you can see how it looks. Reviewers can leave comments right on the rendered copy or on the raw Markdown text.

Want to see this in action? Check out our demo.

Reviewing PDFs or other documents

Product managers and doc writers generally aren’t writing Markdown or code. They’re working in Word, Excel, Power Point, or something more specialized. When they want a review of the latest PRD or section of the manual, they probably just e-mail it out to you, and you probably e-mail them back some replies. Yuck.

Instead, convince management and your doc writers to export their documents as PDF, and then upload them to Review Board. If you have Power Pack installed, or you’re an RBCommons subscriber on a Medium plan or higher, you’ll be able to read through the PDF and comment on any part of it.

This works very similarly to screenshot commenting. Click-and-drag to select a region, and leave a comment. That section will appear along with your comment in the review, just like with code or screenshots.

It’s a much better way of tracking all the feedback around the design or documentation of your product.

You can see what PDF review is like over on our demo page.

So in conclusion…

5 Tips for your RBTools workflow

December 8, 2014December 18, 2014 Christian Hammond 1 Comment

If you’re a Review Board or RBCommons user, you’re probably familiar with RBTools, our handy set of command line tools for working with Review Board. (If you’re not using RBTools, I’m going to tell you how to get started with it in a bit.)

You’re probably most familiar with rbt post, or post-review in older versions. This is the tool that helps you quickly get a change onto Review Board, or to update an existing review request. It’s pretty handy, but how much do you really know about it? Or about the other commands included with RBTools? (Yes, there are others!)

I’m going to show you five of my favorite tips and tricks for RBTools that you may not know about.

5. Opening a browser after posting with `rbt post -o`

When you run rbt post, you usually get something like this:

$ rbt post
Review request #123 posted.

https://reviewboard.example.com/r/123/
https://reviewboard.example.com/r/123/diff/

Those links for opening the review request or diff are useful, but you can save yourself a step by having RBTools open your browser for you. Just pass -o to rbt post, like so:

$ rbt post -o

Your browser of choice will open, ready for editing. Want to do that automatically, every time? Add this to your .reviewboardrc in your home directory:

OPEN_BROWSER = True

4. Check your open review requests with `rbt status`

At some point or another, you’ll want to see what review requests you have open, either as a draft or currently pending review. I myself need to do this at times to help me remember if I’ve already posted something for review.

Sure, you could dig through the dashboard and check. That works great, but it means leaving the command line. That’s where the rbt status command comes in:

$ rbt status
   r/6676 - Add release notes for Review Board 2.0.12.
   r/6258 - Add release notes for Review Board 2.1 beta 1.

rbt status will show you all open review requests for the current repository – their IDs and their summaries. Pass --all and it’ll show you all open review requests across all repositories.

3. Attach files to review requests with `rbt attach`

Review Board makes it pretty easy to drag-and-drop files onto a review request in order to quickly upload them, but it does mean having the file manager and web page open. If you’re a command line junkie like me, you’d probably rather avoid that as much as possible.

rbt attach will let you upload a file to a review request with a single command. Just give it the review request ID, the file to upload, and an optional caption, and you’re done.

Let’s try it.

$ rbt attach 123 screenshot.png
Uploaded screenshot.png to review request 123.

Want to give it a caption?

$ rbt attach --caption "UI screenshot" 123 screenshot.png

2. Apply a review request’s diff to your tree with `rbt patch`

If you’re an open source developer, or you like to thoroughly test other people’s patches as part of reviewing their code, then this tip is for you.

rbt patch pulls down the latest patch (or a specified revision) from a review request and applies it to your tree. It can even create a commit for that patch, if using Git or Mercurial, by running rbt patch -c.

$ rbt patch -c 123
Changes committed to current branch.

We use this when accepting contributions from our own Review Board server. After a thorough review, we run rbt patch -c, edit the commit message as appropriate, and push it.

As a bonus, this will append a Reviewed at <url> line to the bottom of the commit message. If you’re using repository hooks to auto-close review requests (admins, see the “Hooks” link next to a repository in the administration UI), pushing this commit will take care of closing that out for you.

1. Easily update review requests with `rbt post -u`

If you’ve been using RBTools for a good long while, you’re probably used to passing -r <ID> to rbt post, in order to tell it which review request to update. This means having to look up the ID and making sure you don’t type it wrong.

In RBTools 0.6 or newer, we have a much simpler solution. Just pass -u. RBTools will automatically find a matching review request, asking if it’s not completely sure it’s a match, and update it for you. Let’s compare:

$ rbt post -r 123

vs.

$ rbt post -u

It’s much nicer. Get in the habit of using -u. It’s the wave of the future.

What if I’m not using RBTools?

Use it!

Seriously, RBTools is the best way to get the most out of Review Board. You can follow our installation instructions to get started. We’ll soon be announcing new installers to make this easier.

Learn more

The RBTools documentation is a great resource. You can learn about all the RBTools commands, our Python API for interfacing with Review Board, configuration options, and more.

We’ll be posting a new batch of tips and tricks for RBTools soon, plus some advanced Git and Review Board tips.

And now, we’d like to leave you with this:

RBTools 0.6.3 is released!

November 12, 2014 Christian Hammond

Today’s release of RBTools 0.6.3 fixes a handful of annoying little bugs across Git, Mercurial, Subversion, Perforce, and ClearCase. If you use any one of these (and there’s a good chance you do), it’s time to upgrade!

In past releases, failed post operations could leave behind incomplete review requests, which wasn’t always obvious. RBTools will now print out the review request after a failure, making it easier to fix things up without creating a new review request.

We’ve also fixed a bug in the Python API for Review Board that resulted in errors when performing HTTP DELETE operations.

See the release notes for the complete list of fixes.

While this is a fairly small and bug-oriented release, we’re happy to announce that RBTools 0.7 is coming soon, with several new features and native installers for Windows and MacOS X!

Auto-closing review requests when pushing changes

September 29, 2014December 28, 2017 Christian Hammond

We’ve launched a new feature today for simplifying your code review workflow.

If you’re using GitHub, Bitbucket, or Google Code, RBCommons can now automatically close your review requests when you push your commits to your repository, making use of the service’s “post-commit” hooks. You’ll no longer need to click Close -> Submitted, saving time and keeping your dashboard clean.

Usage is simple

Once you’re set up (and we’ll go into that in a minute), all you need to do is include the following in your commit message:

Reviewed at https://rbcommons.com/s/<your-team>/r/<id>/

Or:

Review Request #<id>

Just commit, and your review request will be automatically closed, along with a message containing the commit revision and which branch it was committed to.

Setting this up

Setup depends on which service you’re using for your repositories, but we’ve worked to make it pretty simple.

We’ve added some new buttons to your Team Administration -> Repositories page. You’ll see a “Hooks” button next to any supported repository. Click that, and you’ll see instructions on turning this feature on for your repository. In just seconds, your repository will be set up!

This feature is still new, but has been undergoing testing for several weeks. If you hit any snags, let us know and we’ll help get you going.
