Michael Keppler 91021cb66f Configure classpath for separate test sources in Eclipse
Eclipse Photon supports separating sources and test sources.

There are no functional changes in the IDE, except for test source
folders having a different icon color.

Users of different IDEs than Eclipse are not affected, since the
attribute on the classpath entries will be ignored by their IDE.

David Pursehouse 7ebd434e91 Disable Eclipse warning about unrecognized @SuppressWarnings value
The code base has several @SuppressWarnings annotations to suppress
warnings raised by Error Prone, but those are not recognized by
Eclipse and there is currently no way to tell it about them [1].

Suppress them for now.

David Pursehouse 171f84a041 Use constants from StandardCharsets instead of hard-coded strings
Instead of hard-coding the charset strings "US-ASCII", "UTF-8", and
"ISO-8859-1", use the corresponding constants from StandardCharsets.

UnsupportedEncodingException is not thrown when the StandardCharset
constants are used, so remove the now redundant handling.

Because the encoding names are no longer hard-coded strings, also
remove redundant $NON-NLS warning suppressions.

Also replace existing usages of the constants with static imports.

David Pursehouse 190b575be1 Suppress "Unlikely argument type for equals()" warnings in tests
This new warning was introduced in Eclipse 4.7 Oxygen [1].

The only instances of the warning are in test code that is asserting
that some class does not compare equal to Strings. As in the Gerrit
project [2] these asserts are arguably overkill, but arguably also
a reasonable test of an equals implementation. Ignore the warning in
these cases.

Note that if the project is opened in an earlier version of Eclipse,
a warning "Unsupported @SuppressWarnings" will be emitted.

Matthias Sohn 9906f09868 Partially revert c0ad77d8 "Enhance Eclipse save actions"
Revert the following save actions which were introduced in c0ad77d8:
- always use braces around blocks
- remove unused imports

Other than I expected save actions are run globally on edited files -
and not only on edited code lines only.

Hence revert the save action "Convert control statement bodies to
blocks" which would affect a large number of code lines not affected by
the change editing some small part of a class. This would generate a
large number of changes which may lead to many unnecessary conflicts.
Total number of affected lines across jgit would be around 10k lines.

Also revert "Remove unused imports" since it erroneously removes imports
of some annotations needed by pgm classes using args4j.

Add the following Eclipse save actions executed when saving modified
lines. This should help to reduce manual work needed to maintain a clean

- organize imports
- always use braces around blocks
- add missing annotations
  - @Override including implementation of interface methods
  - @Deprecated
- remove
  - unused imports
  - unnecessary $NON-NLS$ tags
  - redundant type arguments

Also add default values for new settings that were introduced in recent
Eclipse versions up to Neon since we updated save rules the last time.

Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:

  The method <method> of type <type> should be tagged with @Override
  since it actually overrides a superclass method

Justification for this warning is described in:

  http://stackoverflow.com/a/94411/381622

Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.

Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

Matthias Sohn a4feeb0194 Don't rely on default locale when using toUpperCase() and toLowerCase()
Otherwise these methods may produce unexpected results if used for
strings that are intended to be interpreted locale independently.
Examples are programming language identifiers, protocol keys, and HTML
tags. For instance, "TITLE".toLowerCase() in a Turkish locale returns
"t\u0131tle", where '\u0131' is the LATIN SMALL LETTER DOTLESS I
character.

- Remove source_under_test parameters from java_test calls.

- Add vm_args with explicit setting of tmpdir location for http
  tests. This is needed due to upstream changes in temporary
  directory handling [1].

Matthias Sohn e74385b0dd Remove unused package export from bundle org.eclipse.jgit.lfs.test
This may have caused the spurious compile errors sometimes observed in
Eclipse since org.eclipse.jgit.lfs.lib is a split package to enable
testing package private code in bundle org.eclipse.jgit.lfs.

Matthias Sohn 3bae524f6f Support LFS protocol and a file system based LFS storage
Implement LfsProtocolServlet handling the "Git LFS v1 Batch API"
protocol [1]. Add a simple file system based LFS content store and the
debug-lfs-store command to simplify testing.

Introduce a LargeFileRepository interface to enable additional storage
implementation while reusing the same protocol implementation.

At the client side we have to configure the lfs.url, specify that
we use the batch API and we don't use authentication:

  [lfs]
	  url = http://host:port/lfs
	  batch = true
  [lfs "http://host:port/lfs"]
	  access = none

the git-lfs client appends the "objects/batch" to the lfs.url.

Hard code an Authorization header in the FileLfsRepository.getAction
because then git-lfs client will skip asking for credentials. It will
just forward the Authorization header from the response to the
download/upload request.

The FileLfsServlet supports file content storage for "Large File
Storage" (LFS) server as defined by the Github LFS API [2].

- upload and download of large files is probably network bound hence use
  an asynchronous servlet for good scalability
- simple object storage in file system with 2 level fan-out
- use LockFile to protect writing large objects against multiple
  concurrent uploads of the same object
- to prevent corrupt uploads the uploaded file is rejected if its hash
  doesn't match id given in URL

The debug-lfs-store command is used to run the LfsProtocolServlet and,
optionally, the FileLfsServlet which makes it easier to setup a
local test server.

Matthias Sohn 536db18cc6 Implement SHA-256 abstraction
The Large File Storage extension specified by GitHub [1] uses SHA-256 to
compute the ID of large files stored by the extension. Hence implement a
SHA-256 abstraction similar to the SHA-1 abstraction used by JGit.
