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
[-] PROCESSING BUCK FILES...FINISHED 0,0s
Yes, you can't measure no-op build time, given that Buck daemon is

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.

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.

When setting timeout on push, BasePackConnection creates a timer, which
will be terminated when push finishes. But, when using
SmartHttpPushConnection, it dropped the first timer created in the
constructor and then created another timer in doPush. If new threads are
created faster than the gc collects then this may stop the service if
it's hitting the max process limit. Hence don't create a new timer if it
already exists.

PathFilter and PathFilterGroup form JGit's implementation of git's
path-limiting feature in commands like log and diff. To save time
when traversing trees, a path specification
foo/bar/baz
tells the tree walker not to traverse unrelated trees like qux/. It
does that by returning false from include when the tree walker is
visiting qux and true when it is visiting foo.
Unfortunately that test was implemented to be slightly over-eager: it
doesn't only return true when asked whether to visit a subtree "foo"
but when asked about a plain file "foo" as well. As a result, diffs
and logs restricted to some-file/non-existing-suffix unexpectedly
match against some-file:

Pushing with JGit commandline to e.g. Github failed with "unauthorized"
since HttpUrlConnection calls the configured authenticator implicitly.
The problem is that during a push two requests are sent to the server,
first a GET and then a POST (containing the pack data). The first GET
request sent anonymously is rejected with 401 (unauthorized). When an
Authenticator is installed the java.net classes will use the
Authenticator to ask the user for credentials and retry the request.
But this happens under the hood and JGit level code doesn't see that
this happens.
The next request is the POST but since JGit thinks the first GET request
went through anonymously it doesn't add authentication headers to the
POST request. This POST of course also fails with 401 but since this
request contains a lot of body-data streamed from JGit (the pack file!)
the java.net classes can't simply retry the request with authorization
headers. The whole process fails.
Fix this by using Apache httpclient which doesn't use Authenticator to
retrieve credentials. Instead initialize TransportCommand to use the
default credential provider if no other credentials provider was set
explicitly. org.eclipse.jgit.pgm.Main sets this default for the JGit
command line client.

If an application uses PushConnection directly on the native Git wire
protocols JGit should send along the application's expected oldId, not
the advertised value. This allows the remote peer to compare-and-swap
since it was not tested inside JGit.
Discovered when I tried to use a PushConnection (bypassing the
standard PushProcess) and the client blindly overwrote the remote
reference, even though my app had supplied the wrong ObjectId for
the expectedOldObjectId. This was not expected and cost me over an
hour of debugging, plus "corruption" in the remote repository.
By passing along the exact expectedOldObjectId from the app the
remote side can do the check that the application skipped, and
avoid data loss.

JGit's Nullable type was added[1] in the hope of being able to add
nullness annotations that (a) do not preclude building and running
with Java 7 and (b) could be shared by Gerrit, which uses a custom
Nullable type for other reasons[2]. Sharing a type is useful because
Eclipse's null analysis is only able to use one Nullable type at a
time in a given workspace (so for this analysis to function in a
workspace used to develop Gerrit, JGit and Gerrit would need to use
the same Nullable type).
The new Nullable type has CLASS instead of RUNTIME retention because
there wasn't any obvious use for the annotation at run time.
Gerrit uses the Nullable annotation to communicate with Guice. Guice
injection happens at runtime, so it needs to be able to read the
@Nullable annotations at run time[3]. Otherwise Guice produces
provisioning errors, such as
3) null returned by binding at com.google.gerrit.lucene.LuceneChangeIndex$Factory.create()
but parameter 7 of com.google.gerrit.lucene.LuceneChangeIndex.<init>() is not @Nullable
Switch to RUNTIME retention to avoid this.
While at it, update the javadoc to explain more clearly how this
annotation relates to other Nullable types[4]. This should make it
clearer why JGit needed another Nullable type:
A. Avoiding dependency on Java 8
B. RUNTIME retention to allow Guice to read the annotation at run time
C. Named Nullable so Guice can recognize the annotation
D. Not an addition to Java EE's javax.annotation package, to avoid
the split-package problem[2] that prevents the annotation from
being readable at run time when loaded from an OSGi container
E. Avoiding heavyweight dependencies, deprecated dependencies, and
dependencies on package internals

This should mirror the behavior of `git push --atomic` where the
client asks the server to apply all-or-nothing. Some JGit servers
already support this based on a custom DFS backend. InMemoryRepository
is extended to support atomic push for unit testing purposes.
Local disk server side support inside of JGit is a more complex animal
due to the excessive amount of file locking required to protect every
reference as a loose reference.

Recursively copying a tree into a DirCache is a bottleneck for some
algorithms like the in memory merge code in Gerrit Code Review. Drop
a layer down in the stack and use CanonicalTreeParser directly as the
addition logic only processes 1 tree at a time and does not need the
merge sorting feature (or overhead) of TreeWalk.
Combined with 761814fe9c ("DirCacheEntry: Speed up creation by

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.

The checkPath function is available as a byte[] form, in fact the

Having DirCacheEntry take a byte[] -> String -> byte[] to check if
each path is valid is a huge waste of CPU time. On some systems it
can double the time required to read 38,999 files from trees to the
DirCache. This slows down any operation using a DirCache.
