kandi X-RAY | jgit-cookbook Summary

jgit-cookbook is a Java library. jgit-cookbook has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can download it from GitHub.
Provides examples and code snippets for the [JGit](https://eclipse.org/jgit/) Java Git implementation. The JGit framework is rich and diverse, it has two layers, a low-level api and a higher-level set of porcelain commands. This can be a bit intimidating at first as there are lots of classes, some of which are not relevant for most tasks. This project tries to provide a collection of ready-to-run snippets which provide a quick start for building functionality using JGit. Please make sure to take a look at the nicely written [introduction](http://www.codeaffine.com/2015/12/15/getting-started-with-jgit/) and also use the existing [JavaDoc](http://download.eclipse.org/jgit/site/5.5.0.201909110433-r/apidocs/) and the [User Guide](http://wiki.eclipse.org/JGit/User_Guide) as well, as they are well done and provide detailed information and a general overview of JGit respectively. Just import the project in your IDE and start up the Main application, see the Comments in the code for more details. Another simple way to start the sample-server is to run ./gradlew run in the httpserver-directory. If you find these snippets useful and would like to support it, you can [Sponsor the author](https://github.com/sponsors/centic9).

                      Is it possible to use JGit's in-memory repository to add one small file to a big Git repository without checking it out locally?

                      Asked 2020-Oct-12 at 14:01

                      I have a large (several GB) Git repository. I want some application to create small files within that repository and commit the changes. This should happen without checking out those gigabytes to the disk.

                      I found a JGit code sample in which a remote repository is cloned into an in-memory respository.

                      Can I use JGit (something like shown below) in order to add a file to a remote repository without checking it out locally (i. e. without transferring gigabytes of data to the machine where that code will run)?

                      DfsRepositoryDescription repoDesc = new DfsRepositoryDescription();
                      InMemoryRepository repo = new InMemoryRepository(repoDesc);
                      Git git = new Git(repo);
                      git.remoteAdd();
                      git.commit();
                      

                      Update 1: The size of the entire directory (tracked files plus .git) is 1.2G. The size of .git alone is 573M.

                      % du -hs .
                      1.2G    .
                      % du -hs .git
                      573M    .git

                      Note that a checkout in RAM will download the exact same data from the remote. It will just use 1,2G in RAM, rather than on disk, after the clone is completed.

                      You may also want to see how you can create and add a "file" using JGit api, to see if it is a convenient way to add the data you want to your repo.


                      If you want to limit the amount of stuff that's downloaded from your git server : you can create a shallow clone.
                      see this SO answer for example :

                      git clone --depth 1 <repo_url> -b <branch_name>
                      

                      This will download the inner files for the latest commit (a compressed version of the 500M in your case), and run an actual checkout (the 500M) of this commit.

                      You can run this either on disk, or in RAM, depending on your needs.

                      In your situation, this would still require something in the 600-700M usage, in RAM or on disk, including the checked out files,
                      but it would download only ~100M (I'm guessing : check the actual size by running the shallow clone command from your workstation) from the server for the compressed version of the head commit.
