FS: Extract GobblerThread into a private static class
The primary goal is to improve exception readability. Since this is a
standalone thread, just logging the stack trace of the caught
exception is not very useful:
java.io.IOException: Stream closed
at java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:162)
at java.io.BufferedInputStream.read(BufferedInputStream.java:258)
at org.eclipse.jgit.util.FS$2.run(FS.java:451)
Providing a named class eliminates the "FS$2", and including the
command name provides a little more context in the error message.
A future improvement might include the stack trace that created the
GobblerThread as well.

This error happens on nfs file system when you try to read a file that
was deleted or replaced.
When the error happens because the file was deleted, removing it from
the list is the proper way to handle the error, same use case as
FileNotFoundException. When the error happens because the file was
replaced, removing the file from the list will cause the file to be
re-read so it will get the latest version of the file.

Revert "CommitBuilder should check for duplicate parents"
This reverts commit 6bc48cdc62.
Until git v1.7.10.2~29^2~1 (builtin/merge.c: reduce parents early,
2012-04-17), C git merge would make merge commits with duplicate parents
when asked to with a series of commands like the following:
git checkout origin/master
git merge --no-ff origin/master
Nowadays "git merge" removes redundant parents more aggressively
(whenever one parent is an ancestor of another and not just when
duplicates exist) but merges with duplicate parents are still permitted
and can be created with git fast-import or git commit-tree and history
viewers need to be able to cope with them.
CommitBuilder is an interface analagous to commit-tree, so it should
allow duplicate parents. (That said, an option to automatically remove
redundant parents would be useful.)

Don't remove pack from pack list for problems which could be transient
If we hit a corrupt object or invalid pack remove the pack from the pack
list. Other IOException could be transient hence we should not remove
the pack from the list to avoid the problem reported on the Gerrit list
[1]. It looks like in the reported case the pack was removed from the
pack list causing MissingObjectExceptions which disappear when the

Allow explicit configuration of git directory in InitCommand
Native git's "init" command allows to specify the location of the .git
folder with the option "--separate-git-dir". This allows for example to
setup repositories with a non-standard layout. E.g. .git folder under
/repos/a.git and the worktree under /home/git/a. Both directories
contain pointers to the other side: /repos/a.git/config contains
core.worktree=/home/git/a . And /home/git/a/.git is a file containing
"gitdir: /repos/a.git". This commit adds that option to InitCommand.
This feature is needed to support the new submodule layout where the
.git folder of the submodules is under .git/modules/<submodule>.

Add a method to ObjectInserter to read back inserted objects
In the DFS implementation, flushing an inserter writes a new pack to
the storage system and is potentially very slow, but was the only way
to ensure previously-inserted objects were available. For some tasks,
like performing a series of three-way merges, the total size of all
inserted objects may be small enough to avoid flushing the in-memory
buffered data.
DfsOutputStream already provides a read method to read back from the
not-yet-flushed data, so use this to provide an ObjectReader in the
DFS case.
In the file-backed case, objects are written out loosely on the fly,
so the implementation can just return the existing WindowCursor.

example often throws an com.jcraft.jsch.JschException: verify: false.[1]
The issue is still not fixed in JSch 0.1.51.
In such a case it is worth retrying to connect. The number of connection

"ConnectionAttempts" [2].

Enhance reading of git-rebase-todo formatted files
Reading and writing files formatted like the git-rebase-todo files was
hidden in the RebaseCommand. Certain constructs (like leading tabs and
spaces) have not been handled as in native git. Also the upcoming
rebase interactive feature in EGit needs reading/writing these files
independently from a RebaseCommand.
Therefore reading and writing those files has been moved to the
Repository class. RebaseCommand gets smaller because of that and doesn't
have to deal with reading/writing files.
Additional tests for empty todo-list files, or files containing comments
have been added.
