This tool scans all references in the repository and writes out a new
reference pointing to a single commit whose root tree is a RefTree
containing the current refs of this repository.
It alway skips storing the reference it will write to, avoiding the
obvious cycle.
Change-Id: I20b1eeb81c55dc49dd600eac3bf8f90297394113
A group of updates can be applied by updating the tree in one step,
writing out a new root tree, and storing its SHA-1. If references
are stored in RefTrees, comparing two repositories is a matter of
checking if two SHA-1s are identical. Without RefTrees comparing two
repositories requires listing all references and comparing the sets.
Track the "refs/" directory as a root tree by storing references
that point directly at an object as a GITLINK entry in the tree.
For example "refs/heads/master" is written as "heads/master".
Annotated tags also store their peeled value with ^{} suffix, using
"tags/v1.0" and "tags/v1.0^{}" GITLINK entries.
Symbolic references are written as SYMLINK entries with the blob of
the symlink carrying the name of the symbolic reference target.
HEAD is outside of "refs/" namespace so it is stored as a special
"..HEAD" entry. This name is chosen because ".." is not valid in
a reference name and it almost looks like "../HEAD" which names
HEAD if the reader was inside of the "refs/" directory.
A new Command type is required to handle symbolic references and
peeled references.

Currently execution of tests in pgm uses CLIGitCommand which
re-implements few things from Main. Unfortunately this can results in a
different test behavior compared to the real CLI runtime.
The change let CLIGitCommand extend Main and only slightly modifies the
runtime (stream redirection and undesired exit() termination).

To fix this, CmdLineParser must catch, print but do not propagate

In different places (Main, TextBuiltin, CLIGitCommand) we report fatal
errors and at same time want to check for fatal errors in the tests.
Using common API simplifies the error testing and helps to navigate to
the actual error check implementation.

This artifact is used from unzip utility in Gerrit Code Review
build toolchain and thus the file must exist on the file system.

Trailing whitespace is usually removed in properties files so
JGitText did not supply a space between : and the remote message.
Ensure the space exists at runtime by reading the localized string
and appending a space if it is missing.
Messages should be dynamically fetched and not held in a static
class variable, as they can be changed using thread locals.

Today there are plenty of modern build tool systems available in the
wild (in no particular order):
* http://bazel.io
* https://pantsbuild.github.io
* http://shakebuild.com
* https://ninja-build.org
* https://buckbuild.com
The attributes, that all these build tools have in common, are:
* reliable
* correct
* very fast
* reproducible
It must not always be the other build tool, this project is currently
using. Or, quoting Gerrit Code Review maintainer here:
"Friends, don't let friends use <the other build tool system>!"
This change is non-complete implementation of JGit build in Buck,
needed by Gerrit Code Review to replace its dependency with standlone
JGit cell. This is very useful when a developer is working on both
projects and is trying to integrate changes made in JGit in Gerrit.
The supported workflow is:
$ cd jgit
$ emacs <hack>
$ cd ../gerrit
$ buck build --config repositories.jgit=../jgit gerrit
With --config repositories.jgit=../jgit jgit cell is routed through
JGit development tree.
To build jgit, issue:
$ buck build //:jgit

Accept some of the same section keys that fsck does in git-core,
allowing repositories to skip over specific kinds of acceptable
broken objects, e.g.:
[fsck]
duplicateEntries = ignore
zeroPaddedFilemode = ignore
The zeroPaddedFilemode = ignore is a synonym for the JGit specific
allowLeadingZeroFileMode = true. Only accept the JGit key if git-core
key was not specified.

Some ancient objects may be broken, but in a relatively harmless way.
Allow the ObjectChecker caller to whitelist specific objects that are
going to fail checks, but that have been reviewed by a human and decided
the objects are OK enough to permit continued use of.
This avoids needing to rewrite history to scrub the broken objects out.
Honor the git-core fsck.skipList configuration setting when receiving a
push or fetching from a remote repository.

Un-ignored existing CLI tests which run just fine on Java 7+
Don't treat command termination due '-h' option as a fatal error
This avoids duplication of code between receive-pack and fetch-pack paths.
Separate methods are still required to check use of receive.fsckobjects vs.
fetch.fsckobjects, both of which default to transfer.fsckobjects.

Hoist ObjectIdSet up to lib as part of the public API and add
the interface to some common types like PackIndex and JGit custom

type to check a set of objects from a number of storage options.

If a file (e.g. "A") and a subtree file (e.g. "A/foo.c") both appear
in the DirCache this cache should not be written out as a tree object.
The "A" file and "A" subtree conflict with each other in the same tree
and will fail fsck.
Detect this condition during DirCacheBuilder and DirCacheEditor
finish() so the application can be halted early before it updates a
DirCache that might later write an invalid tree structure.

If a PathEdit tries to store a file where a subtree was, or a subtree

Adding a path that already exists but is changing type such as
from symlink to subdirectory requires a NameConflictTreeWalk to
match up the two different entry types that share the same name.
NameConflictTreeWalk needs a bug fix to pop conflicting entries
when PathFilterGroup aborts the walk early so that it does not
allow DirCacheBuilderIterator to copy conflicting entries into
the output cache.
