The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.
Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.

The JSch bundle in Eclipse 3.4 does not export its packages with
version numbers. Use Require-Bundle on version 0.1.37 that comes
with Eclipse 3.4
There is no 0.1.37 in the maven repositories so the pom still refers
to 0.1.41 so the build can get the compile time dependencies right.

Technically our project name is "JGit", not "Java Git". In fact
there is already another project called "JavaGit" (no space) that we
don't want to become confused with. Ensure we always call ourselves
"JGit" in user visible assets, like the bundle name.
Other Eclipse products list their provider as "Eclipse.org",
not "eclipse.org". So list ourselves that way in all of our
plugin.properties files.

This commit actually does three major changes to the way references
are handled within JGit. Unfortunately they were easier to do as
a single massive commit than to break them up into smaller units.
Disambiguate symbolic references:
---------------------------------
Reporting a symbolic reference such as HEAD as though it were
any other normal reference like refs/heads/master causes subtle
programming errors. We have been bitten by this error on several
occasions, as have some downstream applications written by myself.
Instead of reporting HEAD as a reference whose name differs from
its "original name", report it as an actual SymbolicRef object
that the application can test the type and examine the target of.
With this change, Ref is now an abstract type with different
subclasses for the different types.
In the classical example of "HEAD" being a symbolic reference to
branch "refs/heads/master", the Repository.getAllRefs() method
will now return:
Map<String, Ref> all = repository.getAllRefs();
SymbolicRef HEAD = (SymbolicRef) all.get("HEAD");
ObjectIdRef master = (ObjectIdRef) all.get("refs/heads/master");
assertSame(master, HEAD.getTarget());
assertSame(master.getObjectId(), HEAD.getObjectId());
assertEquals("HEAD", HEAD.getName());
assertEquals("refs/heads/master", master.getName());
A nice side-effect of this change is the storage type of the
symbolic reference is no longer ambiguous with the storge type
of the underlying reference it targets. In the above example,
if master was only available in the packed-refs file, then the
following is also true:
assertSame(Ref.Storage.LOOSE, HEAD.getStorage());
assertSame(Ref.Storage.PACKED, master.getStorage());
(Prior to this change we returned the ambiguous storage of
LOOSE_PACKED for HEAD, which was confusing since it wasn't
actually true on disk).
Another nice side-effect of this change is all intermediate
symbolic references are preserved, and are therefore visible
to the application when they walk the target chain. We can
now correctly inspect chains of symbolic references.
As a result of this change the Ref.getOrigName() method has been
removed from the API. Applications should identify a symbolic
reference by testing for isSymbolic() and not by using an arcane
string comparsion between properties.
Abstract the RefDatabase storage:
---------------------------------
RefDatabase is now abstract, similar to ObjectDatabase, and a
new concrete implementation called RefDirectory is used for the
traditional on-disk storage layout. In the future we plan to
support additional implementations, such as a pure in-memory
RefDatabase for unit testing purposes.
Optimize RefDirectory:
----------------------
The implementation of the in-memory reference cache, reading, and
update routines has been completely rewritten. Much of the code
was heavily borrowed or cribbed from the prior implementation,
so copyright notices have been left intact as much as possible.
The RefDirectory cache no longer confuses symbolic references
with normal references. This permits the cache to resolve the
value of a symbolic reference as late as possible, ensuring it
is always current, without needing to maintain reverse pointers.
The cache is now 2 sorted RefLists, rather than 3 HashMaps.
Using sorted lists allows the implementation to reduce the
in-memory footprint when storing many refs. Using specialized
types for the elements allows the code to avoid additional map
lookups for auxiliary stat information.
To improve scan time during getRefs(), the lists are returned via
a copy-on-write contract. Most callers of getRefs() do not modify
the returned collections, so the copy-on-write semantics improves
access on repositories with a large number of packed references.
Iterator traversals of the returned Map<String,Ref> are performed
using a simple merge-join of the two cache lists, ensuring we can
perform the entire traversal in linear time as a function of the
number of references: O(PackedRefs + LooseRefs).
Scans of the loose reference space to update the cache run in
O(LooseRefs log LooseRefs) time, as the directory contents
are sorted before being merged against the in-memory cache.
Since the majority of stable references are kept packed, there
typically are only a handful of reference names to be sorted,
so the sorting cost should not be very high.
Locking is reduced during getRefs() by taking advantage of the
copy-on-write semantics of the improved cache data structure.
This permits concurrent readers to pull back references without
blocking each other. If there is contention updating the cache
during a scan, one or more updates are simply skipped and will
get picked up again in a future scan.
Writing to the $GIT_DIR/packed-refs during reference delete is
now fully atomic. The file is locked, reparsed fresh, and written
back out if a change is necessary. This avoids all race conditions
with concurrent external updates of the packed-refs file.
The RefLogWriter class has been fully folded into RefDirectory
and is therefore deleted. Maintaining the reference's log is
the responsiblity of the database implementation, and not all
implementations will use java.io for access.
Future work still remains to be done to abstract the ReflogReader
class away from local disk IO.

Since Robin reverted using the maven-bundle-plugin to produce the
OSGi manifest, there is no reason for us to reference it from our
build process anymore.
Also, when Robin reverted the to the Eclipse way of doing things,
we failed to update the ignore files to ignore our generated files
but not ignore our tracked .classpath.
Finally, we cannot delete the MANIFEST.MF file during a Maven build,
as this is once again a source file.

Tycho isn't production ready for projects like JGit to be using as
their primary build driver. Some problems we ran into with Tycho
0.6.0 that are preventing us from using it are:
* Tycho can't run offline
The P2 artifact resolver cannot perform its work offline. If the
build system has no network connection, it cannot compile a
project through Tycho. This is insane for a distributed version
control system where developers are used to being offline during
development and local testing.
* Magic state in ~/.m2/repository/.meta/p2-metadata.properties
Earlier iterations of this patch tried to use a hybrid build,
where Tycho was only used for the Eclipse specific feature and P2
update site, and maven-bundle-plugin was used for the other code.
This build seemed to work, but only due to magic Tycho specific
state held in my local home directory. This means builds are not
consistently repeatable across systems, and lead me to believe
I had a valid build, when in fact I did not.
* Manifest-first build produces incomplete POMs
The POM created by the manifest-first build format does not
contain the dependency chain, leading a downstream consumer to
not import the runtime dependencies necessary to execute the
bundle it has imported. In JGit's case, this means JSch isn't
included in our dependency chain.
* Manifest-first build produces POMs unreadable by Maven 2.x
JGit has existing application consumers who are relying on
Maven 2.x builds. Forcing them to step up to an alpha release
of Maven 3 is simply unacceptable.
* OSGi bundle export data management is tedious
Editing each of our pom.xml files to mark a new release is
difficult enough as it is. Editing every MANIFEST.MF file to
list our exported packages and their current version number is
something a machine should do, not a human. Yet the Tycho OSGi
way unfortunately demands that a human do this work.
* OSGi bundle import data management is tedious
There isn't a way in the MANIFEST.MF file format to reuse the
same version tags across all of our imports, but we want to have
a consistent view of our dependencies when we compile JGit.
After wasting more than 2 full days trying to get Tycho to work,
I've decided its a lost cause right now. We need to be chasing down
bugs and critical features, not trying to bridge the gap between
the stable Maven repository format and the undocumented P2 format
used only by Eclipse.
So, switch the build to use Apache Felix's maven-bundle-plugin.
This is the same plugin Jetty uses to produce their OSGi bundle
manifests, and is the same plugin used by the Apache Felix project,
which is an open-source OSGi runtime. It has a reasonable number
of folks using it for production builds, and is running on top of
the stable Maven 2.x code base.
With this switch we get automatically generated MANIFEST.MF files
based on reasonably sane default rules, which reduces the amount
of things we have to maintain by hand. When necessary, we can add
a few lines of XML to our POMs to tweak the output.
Our build artifacts are still fully compatible with Maven 2.x, so
any downstream consumers are still able to use our build products,
without stepping up to Maven 3.x. Our artifacts are also valid as
OSGi bundles, provided they are organized on disk into a repository
that the runtime can read.
With maven-bundle-plugin the build runs offline, as much as Maven
2.x is able to run offline anyway, so we're able to return to a
distributed development environment again.
By generating MANIFEST.MF at the top level of each project (and
therefore outside of the target directory), we're still compatible
with Eclipse's PDE tooling. Our projects can be imported as standard
Maven projects using the m2eclipse plugin, but the PDE will think
they are vaild plugins and make them available for plugin builds,
or while debugging another workbench.
This change also completely removes Tycho from the build.
Unfortunately, Tycho 0.6.0's pom-first dependency resolver is broken
when resolving a pom-first plugin bundle through a manifest-first
feature package, so bundle org.eclipse.jgit can't be resolved,
even though it might actually exist in the local Maven repository.
Rather than fight with Tycho any further, I'm just declaring it
plugina-non-grata and ripping it out of the build.
Since there are very few tools to build a P2 format repository, and
no documentation on how to create one without running the Eclipse
UI manually by poking buttons, I'm declaring that we are not going
to produce a P2 update site from our automated builds.
