* Enable and fix warnings about redundant specification of type argumentsDavid Pursehouse2017-02-201-1/+1
| | | | | | | | | | Since the introduction of generic type parameter inference in Java 7, it's not necessary to explicitly specify the type of generic parameters.

* Decide whether to "Accept-Encoding: gzip" on a request-by-request basisZhen Chen2016-12-091-2/+5
| | | | | | | | | When the reply is already compressed (e.g. a packfile fetched using dumb HTTP), "Content-Encoding: gzip" wastes bandwidth relative to sending the content raw. So don't "Accept-Encoding: gzip" for such requests. Change-Id: Id25702c0b0ed2895df8e9790052c3417d713572c Signed-off-by: Zhen Chen <czhen@google.com>
* JGit 3.0: move internal classes into an internal subpackageShawn Pearce2013-03-181-1/+1
| | | | | | | | This breaks all existing callers once. Applications are not supposed to build against the internal storage API unless they can accept API churn and make necessary updates as versions change. Change-Id: I2ab1327c202ef2003565e1b0770a583970e432e9
* Mark non-externalizable strings as suchRobin Rosenberg2012-12-271-8/+8
| | | | | | | | | | A few classes such as Constanrs are marked with @SuppressWarnings, as are toString() methods with many liternal, but otherwise $NLS-n$ is used for string containing text that should not be translated. A few literals may fall into the gray zone, but mostly I've tried to only tag the obvious ones. Change-Id: I22e50a77e2bf9e0b842a66bdf674e8fa1692f590

* Move FileRepository to storage.file.FileRepositoryShawn O. Pearce2010-06-261-1/+1
| | | | | | | | | | | | This move isolates all of the local file specific implementation code into a single package, where their package-private methods and support classes are properly hidden away from the rest of the core library. Because of the sheer number of files impacted, I have limited this change to only the renames and the updated imports. Change-Id: Icca4884e1a418f83f8b617d0c4c78b73d8a4bd17 Signed-off-by: Shawn O.

* Externalize strings from JGitSasa Zivkov2010-05-191-5/+7
| | | | | | | | | | | | | | | 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.

* Rewrite reference handling to be abstract and accurateShawn O. Pearce2010-01-231-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move pure IO utility functions to a utility class of its own.Robin Rosenberg2009-10-311-2/+2
| | | | | | | | | | | | | According the javadoc, and implied by the name of the class, NB is about network byte order. The purpose of moving the IO only, and non-byte order related functions to another class is to make it easier for new contributors to understand that they can use these functions in general and it's also makes it easier to understand where to put new IO related utility functions Change-Id: I4a9f6b39d5564bc8a694b366e7ff3cc758c5181b Signed-off-by: Robin Rosenberg <robin.rosenberg@dewire.com> Signed-off-by: Shawn O.
