Bedrock Analytics speeds up with Bitbucket

By on January 12, 2015

[Editor’s Note: This is the first of a series of guest blog posts around Bitbucket. This post is written by Will Salcido, CEO & Co-Founder of Bedrock Analytics Corporation. If you are interested in writing a guest post about your usage of Bitbucket, or best practices & tips, please contact us at, and we will reach out to you.]


Will Salcido is the CEO & Co-Founder of Bedrock Analytics Corporation. Will spent over a decade in the field of analytics across several leadership roles at Nestle, Novartis, Ghirardelli & Lindt. He developed analytical software for Ghirardelli that led him to solo-deploy the solution across 11 European countries in 2011. Bedrock Analytics is a data visualization and analytics software company based out of Oakland, CA.

The idea for what would become Bedrock Analytics came to me while I was working in Stockholm, Sweden. After nine international deployments of the analytical solution I had built for Ghirardelli & Lindt, I discovered that nearly all consumer product companies had similar issues working with data. Bedrock’s data visualization software enables consumer product companies to extract actionable insights from retail data. The software fills a skills gap for small to midsized companies and makes larger enterprises more efficient by automating the discovery of insights. Our customer base of consumer product companies spans throughout North America, Central America, and Europe.


In the very beginning, we had a single person with access to the source code. It wasn’t until we started hiring additional engineering staff that we began exploring the different hosted repository providers. We tested a few options and after careful deliberation, we ended up choosing Bitbucket.

We chose Bitbucket since it allowed us to collaborate within our development team using the built-in wiki and the “pull request’ workflow, and had the ability to scale along with our company. We recently hired engineering talent in Eastern Europe and Bitbucket allowed us to manage our development projects in an efficient manner. Bitbucket has made it possible to segregate our code in ways that enabled different specialized teams to work in parallel on different portions of our source code while keeping everything organized in a single platform. Most importantly, we are also looking forward to integrating Bitbucket with other Atlassian and non-Atlassian products as we continue to grow.

Our engineers like the fact that Bitbucket offers unlimited private repositories to store smaller ongoing projects. Having the ability to track changes made in each repository has saved the team countless hours. We are in the middle of scaling our processes and Bitbucket has become a critical part of how we are gaining efficiencies within our development team.

Like any fast-growing startup, our company’s greatest advantage is our speed. Bedrock Analytics speeds up with Bitbucket.


Update on Git and Mercurial vulnerability

By on December 18, 2014

The maintainers of the Git and Mercurial open source projects have identified a vulnerability in the Git and Mercurial clients for Macintosh and Windows operating systems that could allow critical files to be overwritten with unwanted files, including executables.

Because this is a client-side vulnerability, Bitbucket itself is not affected; however, we recommend you update your Git client with one of the published Git maintenance releases (, 1.9.5, 2.0.5, 2.1.4 and 2.2.1) or Mercurial client with the latest release.

If you are also using SourceTree please follow these instructions to update your Git client:

Bitbucket: building high-quality software with speed and scale

By on December 1, 2014

Bitbucket helps teams build better software through collaboration. Our customers want tools they can trust and software that won’t break under stress or load. Robustness, reliability, and security are very important attributes of our software. But, like any other software, sometimes things may go wrong. Anticipating those situations and building good diagnostics and recovery features in the product is crucial.

Quality at Bitbucket

Our Bitbucket team doesn’t include an army of dedicated testers who would spend weeks before the release to find bugs. That’s inefficient and creates a sub-optimal split of responsibilities that leads to poor quality. Instead, we take a very different approach. Every developer on the team is responsible for the quality of the software. But not every developer is good at testing. That’s why we have a very small team of QA engineers whose primary goal is to enable every developer to do a better job with quality. It is usually achieved through the following tasks:

That’s why QA in our team stands for “quality assistance” and not “quality assurance”.

The challenges of scale

But it’s not that simple, especially if you’re building high-quality products at ever-increasing speed and scale with a small QA team. As Adrian Cockroft once said “scale breaks hardware, speed breaks software and speed at scale breaks everything!”. There are tons of problems to solve. Most importantly, there is a dire need for innovative approaches and tools.

Good engineering practices

In order to achieve our goals of building quality at scale we use some of the following tactics, which we are happy to share with the Bitbucket community:

This is just the tip of the iceberg. If you’re interested to learn more about how we do QA at Atlassian and if you’re in Austin, TX on 9th of December – join us for meetup and drinks. We’re also hiring, so check out this page if you’re interested.

POODLE and the end of SSL 3.0 on Bitbucket

By on October 15, 2014

As mentioned on Atlassian’s main blog, we’ve decided to end SSL 3.0 support on in the wake of the newly-published POODLE exploit. Once all the facts were in, the choice was easy, and we acted quickly to address the issue. As our customer, though, you should know why we did what we did.

In the POODLE exploit, a well-placed attacker can trick each end of an SSL transaction into downgrading to an older, insecure, cipher. Once the connection is established, the attacker can become man-in-the-middle and compromise the data going back and forth between server and client.

The exploit relies on both ends’ willingness to communicate over SSL 3.0. If just one end of the transaction is unwilling to cooperate, then the attack fails altogether. Some older browsers or Git/Mercurial clients may not be able to use the newer TLS standard, though – so why did we choose to disable SSL 3.0 outright?

  1. It’s the recommended solution to the problem. Möller’s paper describing the exploit goes into further detail here, especially regarding flaws in CBC block cipher padding, but the gist is that SSL 3.0 can no longer be trusted as an encryption mechanism; it’s fundamentally flawed, and it will not be fixed. The optimal solution is to disable SSL 3.0 on our end and force everyone to use some flavor of TLS instead.
  2. It has minimal impact on our users. All of the browsers we support can handle the newer TLS encryption standard, as can most of the Git and Mercurial clients that communicate with our servers over HTTPS, and the change has no effect whatsoever on SSH connections.
  3. It protects all of our users – even the ones whose stuff breaks because of it. We want to ensure that all of our users’ HTTPS sessions are unaffected by POODLE, so we’ve done the most effective thing to protect Bitbucket traffic from that particular attack (and a few others). We can’t protect our users from other sites, though, so if this change breaks your browser or client then (unfortunately) you need to upgrade ASAP.

The safety and security of your data are our #1 priority, so this change is effective immediately. If you need further assistance, then please contact us at

P.S. If you’d like more background on SSL, Wikipedia has an excellent article.

Bitbucket notifications to HipChat just got even better

By on October 7, 2014

HipChat notifications from Bitbucket are a great way to keep your team up to date on changes to their code repositories – no matter where they are. For example, your team can receive notifications in the HipChat room you use to collaborate whenever a commit is pushed to the repo. But of course, there’s a lot more happening on your repositories than just new commits. Issues and pull requests are a big part of your development workflow, so with our new HipChat add-on for Bitbucket, we’ve made it dead-simple to send notifications about those too.

Bitbucket’s new HipChat add-on includes the following notifications:

Bitbucket notifications in HipChat

Our new add-on is also easy to install and configure. Just look for ‘HipChat integration’ in the menu when managing your team or personal account. Once the add-on is installed, any administrator of a repository can configure notifications. Notifications can be added or configured when managing an account or managing a repository. When you manage your account, you will be able to view and manage notifications across all repositories owned by the account. When you manage a repository you will be able to view and manage notifications for that repository.

Google Cloud Push-to-Deploy comes to Bitbucket

By on September 18, 2014

If you frequently deliver apps to the cloud, you know every extra step to package and deploy your code introduces risk and can add hours to the process.  Now, with Push-to-deploy support for Bitbucket, deploying changes to your application in App Engine is easy, safe and fast.


You can automatically trigger a deployment of your Java, Python or PHP app to App Engine by pushing code to your Bitbucket repo’s master branch or by merging an approved pull request.   Simply connect your App Engine project to your Bitbucket Git repo.

Visit the Google Cloud Platform blog for the detailed instructions to connect your App Engine projects to your Bitbucket repos.

Introducing Pull Request Tasks

By on September 16, 2014

Pull requests in Bitbucket are a great way to share proposed code changes for review and get feedback from your team.  Of course, this typically leads to discussions and feedback in comments, which might result in further changes to the code. While great for improving code quality, feedback via comments can get lost easily. Now, with pull request tasks, you can turn feedback into actionable tasks. Never miss a crucial change. 

create pull request task

To create a task, select Create task within a comment and enter the task info. You can also highlight the relevant text to fill-in the info before you select Create task.

pull request task list

Once you create tasks, you no longer have to search through all of the comments on a pull request to find follow-up items.  You can keep track of all open and resolved tasks with a consolidated list available from the top of a pull request.

The Inner Guts of Bitbucket

By on August 11, 2014

Recently our teammate and Bitbucket engineer Erik Van Zijst had the opportunity to present at Euro Python 2014 in Berlin. Check out this video of his session on the Inner Guts of Bitbucket and get a detailed overview of our current architecture at all layers from Gunicorn and Django to Celery and HAProxy to NFS.

In addition to the inside scoop into Bitbucket’s inner workings, this video covers some war stories and shows how we too have to learn things the hard way sometimes.

Scheduled downtime for database maintenance

By on June 11, 2014

In the last few days, Bitbucket experienced intermittent database issues which caused the site to become unavailable for several minutes at a time. These outages are far beyond what we consider acceptable as a service provider, and we sincerely apologize for any inconvenience this caused.

We continue to investigate these database issues and our goal is to resolve these issues permanently as soon as possible. As part of our on-going investigation we will be be making Bitbucket unavailable for up to four hours starting Saturday, June 14, 2014 at 10:00:00 Pacific to make database configuration changes and upgrades.

Please subscribe to to receive instant updates via email, SMS or RSS as we progress through the downtime. Thank you for your patience as we work to increase Bitbucket’s performance and reliability. Please contact us if you have any questions or concerns.

Repository size limits

By on May 30, 2014

In order to improve and maintain the overall performance for everyone who uses Bitbucket, we are rolling out size limits on newly-created repositories. Starting today, repository size limits will be:

If you already have a repository that is larger than the 2GB limit, your repository has been grandfathered so you won’t have any issues. Should you find your new repository approaching the 1GB soft limit, check out our documentation on how to reduce repository sizes or our blog “How to handle big repositories”.

Of course, Bitbucket still offers unlimited private repositories free for five users!
