Robin Rosenberg	fa4c3fe461	JGit plugin not compatible with Eclipse 3.4 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.

Shawn O. Pearce	0238a21b62	Correct bundle, provider names to be consistent 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.

Shawn O. Pearce	01b5392cdb	Rewrite reference handling to be abstract and accurate 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. Change-Id: I26b9287c45a4b2d2be35ba2849daa316f5eec85d Signed-off-by: Shawn O.

Matthias Sohn	407fe631ae	Use build timestamp as OSGi version qualifier Translate the version qualifier using maven-antrun-plugin since we want manifest-first and currently cannot rely on Tycho for the JGit build.

Shawn O. Pearce	20b4d4740a	Finish removing Apache Felix maven-bundle-plugin 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. Change-Id: I53f77f2002cb4285f728968829560e835651e188 Signed-off-by: Shawn O.

Shawn O. Pearce	fc5fc70e2e	Switch build to Apache Felix maven-bundle-plugin 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.

Shawn O. Pearce	dad52baae8	Refactor our Maven build to be modular Drop our simple and stupid jgit.sh and instead rely upon Maven for the command line based build. Maven is relatively simple to download and install, and doesn't require the entire Eclipse IDE. To avoid too much refactoring of the current code we reuse the existing src/ directory within each plugin, and treat each of the existing OSGI bundles as one Maven artifact. The command line wrapper jgit.sh no longer works in the uncompiled state, as we don't know where to obtain our JSch or args4j from. Developers will now need to compile it with `mvn package`, or run our Main class from within an IDE which has the proper classpath.

Mykola Nikishov	cf2edb6518	Move AWT UI code to new org.eclipse.jgit.ui bundle This new UI bundle contains the org.eclipse.jgit.awtui package, which was moved out of the org.eclipse.jgit bundle. org.eclipse.jgit.pgm depends on org.eclipse.jgit.ui, so we need to update the classpath and make_jgit.sh to include it. This move takes the awtui classes out of the Maven build, which means we are no longer able to distribute these classes to our downstream Maven customers. The entire Maven package structure needs to be overhauled so that Eclipse bundle matches 1:1 with the Maven artifact.
