Protocol V2: respect MAX_HAVES only once we got at least one ACK The negotiation in the git protocol contains a cutoff: if the client has sent more than MAX_HAVES "have" lines without getting an ACK, it gives up and sends a "done". MAX_HAVES is 256. However, this cutoff must kick in only if at least one ACK has been received. Otherwise the client may give up way too early, which makes the server send all its history. See [1]. This was missed when protocol V2 was implemented for fetching in JGit in commit 0853a241. Compare also C git commit 0b07eecf6ed.[2] C git had the same bug.[3][4] [1] https://github.com/git/git/blob/6c430a647cb9/Documentation/technical/pack-protocol.txt#L385 [2] https://github.com/git/git/commit/0b07eecf6ed [3] https://lore.kernel.org/git/b7f5bfb9-61fb-2552-4399-b744428728e4@suse.cz/ [4] https://lore.kernel.org/git/20200422084254.GA27502@furthur.local/ Bug: 553083 Change-Id: I1f4e2cc16b5eed6971d981d472329185abb9e4a9 Signed-off-by: Thomas Wolf <thomas.wolf@paranor.ch>
An implementation of the Git version control system in pure Java.
This project is licensed under the EDL (Eclipse Distribution License).
JGit can be imported straight into Eclipse and built and tested from there. It can be built from the command line using Maven or Bazel. The CI builds use Maven and run on Jenkins.
org.eclipse.jgit
A pure Java library capable of being run standalone, with no additional support libraries. It provides classes to read and write a Git repository and operate on a working directory.
All portions of JGit are covered by the EDL. Absolutely no GPL, LGPL or EPL contributions are accepted within this package.
org.eclipse.jgit.ant
Ant tasks based on JGit.
org.eclipse.jgit.archive
Support for exporting to various archive formats (zip etc).
org.eclipse.jgit.http.apache
Apache httpclient support.
org.eclipse.jgit.http.server
Server for the smart and dumb Git HTTP protocol.
org.eclipse.jgit.lfs
Support for LFS (Large File Storage).
org.eclipse.jgit.lfs.server
Basic LFS server support.
org.eclipse.jgit.packaging
Production of Eclipse features and p2 repository for JGit. See the JGit Wiki on why and how to use this module.
org.eclipse.jgit.pgm
Command-line interface Git commands implemented using JGit (“pgm” stands for program).
org.eclipse.jgit.ssh.apache
Client support for the ssh protocol based on Apache Mina sshd.
org.eclipse.jgit.ui
Simple UI for displaying git log.
Native symbolic links are supported, provided the file system supports them. For Windows you must use a non-administrator account and have the SeCreateSymbolicLinkPrivilege.
Only the timestamp of the index is used by JGit if the index is dirty.
JGit requires at least a Java 8 JDK.
CRLF conversion is performed depending on the core.autocrlf
setting, however Git for Windows by default stores that setting during installation in the “system wide” configuration file. If Git is not installed, use the global or repository configuration for the core.autocrlf setting.
The system wide configuration file is located relative to where C Git is installed. Make sure Git can be found via the PATH environment variable. When installing Git for Windows check the “Run Git from the Windows Command Prompt” option. There are other options like Eclipse settings that can be used for pointing out where C Git is installed. Modifying PATH is the recommended option if C Git is installed.
We try to use the same notation of $HOME
as C Git does. On Windows this is often not the same value as the user.home
system property.
org.eclipse.jgit
Read loose and packed commits, trees, blobs, including deltafied objects.
Read objects from shared repositories
Write loose commits, trees, blobs.
Write blobs from local files or Java InputStreams.
Read blobs as Java InputStreams.
Copy trees to local directory, or local directory to a tree.
Lazily loads objects as necessary.
Read and write .git/config files.
Create a new repository.
Read and write refs, including walking through symrefs.
Read, update and write the Git index.
Checkout in dirty working directory if trivial.
Walk the history from a given set of commits looking for commits introducing changes in files under a specified path.
Object transport
Fetch via ssh, git, http, Amazon S3 and bundles. Push via ssh, git and Amazon S3. JGit does not yet deltify the pushed packs so they may be a lot larger than C Git packs.
Garbage collection
Merge
Rebase
And much more
