Introduce config parameter core.trustfolderstat JGit's ObjectDirectory implements the optimization that it remembers the pack folders (.git/objects/pack) lastModified timestamp and doesn't check for new packfiles in this folder if the lastModified attribute has not changed. In environments using NFS this can cause trouble. If multiple JGit instances from multiple machines work on the same repository and one instance creates a new ref and a new packfile (e.g. by doing a fetch) then the other machines may detect the new ref but can't resolve the referenced object because it doesn't detect that pack folder has a new packfile. That's because NFS may cache file/folder metadata for quite a long time and the pack folders modification time is not updated although a new packfile is there and could be read. The new config parameter core.trustfolderstat controls this behaviour. The default is true and jgits behaviours is unchanged. But if this parameter is set to false then jgit doesn't trust the pack directories lastmodified anymore. Instead it will always iterate through the content of that folder to detect new packfiles.

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.console
Support for reading passwords from the console without echoing them. Requires Java 6.
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.
org.eclipse.jgit.junit
Helpers for unit testing
org.eclipse.jgit.test
Unit tests for org.eclipse.jgit
org.eclipse.jgit.java7.test
Unit tests for Java 7 specific features
org.eclipse.jgit.ant.test
org.eclipse.jgit.pgm.test
org.eclipse.jgit.http.test
org.eclipse.jgit.junit.test
No further description needed
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.
Don‘t try the library with a JDK other than 1.6 (Java 6) unless you are prepared to investigate problems yourself. JDK 1.5.0_11 and later Java 5 versions may work. Earlier versions do not. JDK 1.4 is not supported. Apple’s Java 1.5.0_07 is reported to work acceptably. We have no information about other vendors. Please report your findings if you try.
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 the jgit.gitprefix system property or 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.
