Why Microservices Matter

All successful applications grow more complex over time, and that complexity creates challenges in development. There are two essential strategies to manage this problem: a team can keep everything together (create a monolith) or a team can divide a project into smaller pieces (create microservices).

Update Git clients on Windows and OS X

Last week, a security fix was released for Git. The fix patches a bug in the Git client that is exploitable on operating systems with case insensitive file systems such as Windows and OS X.

Heroku has updated the Git installer that we ship with Toolbelt for Windows. We have also removed an old Git version from the OS X installer (it was not generally used).

In addition, we’ve added a Git version warning in Toolbelt that will prompt you to update Git if you’re using a vulnerable version on Windows (shown here) or OS X:

$ heroku apps
WARNING: Your version of git is 1.9.3. Which has serious security vulnerabilities.                                               
More information here: https://blog.heroku.com/archives/2014/12/23/update_your_git_clients_on_windows_and_os_x

Heroku Toolbelt ships msysGit for Windows and users should update to 1.9.5, available from the msysGit website. OS X users should update their system Git using, for example, the OS X installers or using Homebrew.

Details of the exploit are available on the Git Blame blog and from the Git mailing list announcement.

HTTP Git now Generally Available

Today we’re happy to announce that the HTTP Git beta is over and that HTTP Git is fully ready for production.

The beta was launched less than a month ago and we are already handling thousands of HTTP Git builds per day. In addition, HTTP Git powers the Dropbox Sync beta, making sure that Dropbox folders and Heroku repos are up-to-date.

Over the past month, we have seen great adoption from partners, and Travis CI is using HTTP Git as the default git strategy for Heroku deployments.

We encountered few issues during the beta, and we’re confident that HTTP Git is the best Git implementation for most Heroku users. For that reason, we’re making HTTP Git the default setup when repos are configured by Heroku tooling. We will keep SSH Git as an option and SSH Git still works for all repos on Heroku. You can use SSH Git and HTTP Git (and Dropbox Sync) interchangeably as needed by you and your collaborators. Read on for details.
