![]() Instead of checking every entry for .gitattributes only look for the entry on request by TreeWalk. This avoids impacting uses like RevWalk filtering history. When the attrs is requested skip to the start of the tree and look for .gitattributes until either it is found, or it is impossible to be present. Due to the sorting rules of tree entries .gitattributes should be among the first or second entries in the tree so very few entries will need to be considered. Waiting to find the .gitattributes file by native ordering may miss attrs for files like .config, which sorts before .gitattributes. Starting from the front of the tree on demand ensures the attributes are parsed as early as necessary to process any entry in the tree. Due to TreeWalk recursively processing up the tree of iterators we cannot just reset the current CanonicalTreeParser to the start as parent parsers share the same path buffer as their children. Resetting a parent to look for .gitattributes may overwrite path buffer data used by a child iterator. Work around this by building a new temporary CanonicalTreeParser instance.

Java Git
An implementation of the Git version control system in pure Java.
This package is licensed under the EDL (Eclipse Distribution License).
JGit can be imported straight into Eclipse, built and tested from there, but the automated builds use Maven.
-
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.java7
Extensions for users of Java 7.
-
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.pgm
Command-line interface Git commands implemented using JGit ("pgm" stands for program).
-
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.
Tests
-
org.eclipse.jgit.junit

Warnings/Caveats
-
Native smbolic links are supported, but only if you are using Java 7 or newer and include the org.eclipse.jgit.java7 jar/bundle in the classpath, provided the file system supports them. For Windows you must have Windows Vista/Windows 2008 or newer, 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 7 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.
Package Features
-
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.
