DevOps, Git, and Agile updates from the team building Azure DevOps
November 11, 2019Nov 11, 201911/11/19In a previous blog series, we announced that Git has a new commit-graph feature, and described some future directions. Since then, the commit-graph feature has grown and evolved. In the recently released Git version 2.24.0, the commit-graph is enabled by default!
October 23, 2019Oct 23, 201910/23/19 Coding is a team sport. To help developers be more efficient, we are excited to announce the new Azure Repos app for Microsoft Teams
August 16, 2019Aug 16, 201908/16/19Understanding the way Git defines Δfile changes and merge conflicts in pull requests.
August 6, 2019Aug 6, 201908/6/19A deep dive into using the new Git Trace2 feature to study Git performance problems on very large repos.
June 6, 2019Jun 6, 201906/6/19One of the more powerful git commands is the cherry-pick command. This can be an extremely powerful component of many git workflows such as the Azure DevOps team's Release Flow. To highlight a common use-case for it, let’s talk about hot-fixing release branches.
May 15, 2019May 15, 201905/15/19In previous posts I’ve talked about performance improvements that our team contributed to the Git community. At Microsoft, we’ve been pushing Git to its limits with the largest and busiest Git repositories on the planet, improving core Git as we go and sending these improvements back upstream.
October 5, 2018Oct 5, 201810/5/18Today, the Git project has announced a security vulnerability: there is a security issue in recursively cloning submodules that can lead to arbitrary code execution. The Azure DevOps team encourages you to examine whether you are on an affected platform and, if so, upgrade your Git clients to the latest version.
July 16, 2018Jul 16, 201807/16/18We’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.
July 9, 2018Jul 9, 201807/9/18Earlier, 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.
July 2, 2018Jul 2, 201807/2/18Earlier, 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.
