You will most likely not need this information. This line displays some internal Git metadata. We can see that a/diff_test.txt and b/diff_test.txt have been passed to the diff. This line displays the input sources of the diff. diff -git a/example_diff.txt b/example_diff.txt index 532ce54.0f42eb5 100644 - a/example_diff.txt +++ b/example_diff.txt -1 +1 -examplediff +example diff Comparison input diff -git a/example_diff.txt b/example_diff.txt For now we will use file comparison to understand the command. In most cases, #1 and #2 would be the same file, but it could also be commits, branches, etc. Let us compares two items with each other: item #1and item #2.

Patch format means displaying the lines that are different (added or deleted) between two versions. The differences will be shown in patch format. Git diff will show you any uncommitted changes since the last commit. These data sources can be commits, branches, files and more. git diff is a multi-use Git command that when executed runs a diff function on Git data sources.

Git provides a command diff which compares two input data sets and outputs the changes between them. Assume we want to compare the changes between the tag 4.0.The main objective of version control is to enable you to manage changes made on the same files. In this example, I'm using the public lodash/lodash repository. It allows me to fetch the two individual commits using the git command and compare then to determine changed filenames. After a bit of trial and error, I ultimately abandoned the GitHub API approach.Īfter some further digging, I came across a StackOverflow post that gave me a third option. The get-commits API could work but it means making multiple paged requests for a large amount of data just to get the changed paths. The compare API is limited to 250 commits so that couldn't be relied on. The GitHub REST API includes a compare API and a list-commits API. A shallow clone would not be sufficient as it would not capture the history of changes back to the previous release. It meant cloning a potentially large and growing repository at the start of the build. The first option was one I wanted to avoid.

Use the GitHub API to retrieve information about the commits.

Clone the full repository manually in a CodeBuild step.

I looked at two options to find out folders which had seen changes since the last successful deployment: This is a technique described well in this Shippable blog post. I wanted to run these kind of checks to determine which microservices in our monorepo had changed so I knew which ones to build and redeploy. Some CI environments will give you a 'shallow clone' without the full Git history, leaving you with a similar challenge. This makes it impossible to run checks on what has changed since a previous build or even to determine what has changed in the commit that triggered your build.

Instead of giving you access to a cloned repo, AWS CodeDeploy gives you a snapshot of your code without the. Other tools, and I am talking specifically about AWS CodeDeploy, take a different approach. When I used Jenkins, Travis or Circle CI, I had access to the cloned Git repository and could use git log, git ls-remote and git diff without any problem. This will usually be in your automated build environment. There are some cases where you want to find out information about changes in your Git repository without having to clone the full repository.
