We’ve been discussing the commit-graph feature in Git 2.18 and how we can use generation numbers to accelerate commit walks. One area where we can get significant speedup is when presenting output in topological order. This allows us to walk a much smaller list of commits than before.
Earlier, we announced that Git 2.18 contains a new commit-graph feature, and we discussed the commit-graph file format. As shipped in Git 2.18, this file only speeds up commit walks by a constant multiple, due to parsing structured data from the commit-graph file.
Earlier, we announced the commit-graph feature in Git 2.18 and talked about some of its performance benefits. Today, we’ll discuss some if the technical details about how the commit-graph feature works, including some helpful properties of its file format. This file speeds up commit-graph walks so much that we were able to identify other ways to speed up these walks using small optimizations.
Have you ever run gitk and waited a few seconds before the window appears? Have you struggled to visualize your commit history into a sane order of contributions instead of a stream of parallel work? Have you ever run a force-push and waited seconds for Git to give any output?
Visual Studio Team Services (VSTS) offers a suite of DevOps capabilities to developers including Source control, Agile planning, Build, Release, Test and more. But until now all these features require the user to first login using a Microsoft Account before they can be used.
Git was originally designed for Unix systems and still today, all the build tools for the Git codebase assume you have standard Unix tools available in your path. If you have an open-source mindset and want to start contributing to Git,
Visual Studio Team Services (VSTS) hosts the largest Git repository in the world: the Windows source code. Keeping a primary copy of the code available in the cloud and having it be performant while being updated by over 4000 users at the same time is a monumental achievement,
A DevSecOps best practice is root cause analysis, so that we can learn from live site incidents and prevent their recurrence. Equifax made news recently with the exfiltration of data from half the US population. This is a sobering opportunity to look at the root cause.
Since the creation of the Marketplace, we have seen strong demand for tools to work with Amazon Web Services. I am so thrilled that this month the search for those tools comes to an end. In addition to Amazon releasing their AWS Tools,
If you are interested in Microsoft Visual Studio Team Services (VSTS) platform and Java development, maybe you know that VSTS has everything you need to organize CI/CD pipeline for your Java application development. Visual Studio ALM Blog has a lot of useful and helpful resources describing how to build and deploy your Java application and artifacts to Azure App Service or Azure VM running lightweight open source Tomcat or Jetty servlet container with VSTS.
