Then list of packed refs was cached in RefDirectory based on mtime of
the packed-refs file. This may fail on NFS when attributes are cached.
A cached mtime of the packed-refs file could cause JGit to trust the
cached content of this file and to overlook that the file is modified.
Honor the config option trustFolderStats and always read the packed-refs
content if the option is false. By default this option is set to true
and this fix is not active.

Jsch 0.1.54 passes on the values from ~/.ssh/config for
"ServerAliveInterval" and "ConnectTimeout" as read from
the config file to java.net.Socket.setSoTimeout(). That
method expects milliseconds, but the values in the config
file are seconds!
The missing conversion in Jsch means that the timeout is
set way too low, and if the server doesn't respond within
that very short time frame, Jsch kills the connection and
then throws an exception with a message such as "session is
down" or "timeout in waiting for rekeying process".
As a work-around, do the conversion to milliseconds in the
Jsch-facing Config interface of OpenSshConfig. That way Jsch
already gets these values as milliseconds.

it from the object directory. This resolution is already done when
creating the object directory, so simplify the call by just adding a

Currently, unless RequestPolicy#ANY is used, UploadPack rejects all
non-commit "want" lines unless they were advertized. This is fine,
except when "uploadpack.allowreachablesha1inwant" is true
(corresponding to RequestPolicy#REACHABLE_COMMIT), in which case one
would expect that "want"-ing anything reachable would work.
(There is no restriction that "want" lines must only contain commits -
it is allowed for refs to directly point to trees and blobs, and
requesting for them using "want" lines works.)
This commit has been written to avoid performance regressions as much
as possible. In the usual (and currently working) case where the only
unadvertized things requested are commits, we do a standard RevWalk in
order to avoid incurring the cost of loading bitmaps. However, if
unadvertized non-commits are requested, bitmaps are used instead, and
if there are no bitmaps, a WantNotValidException is thrown (as is
currently done).

JSch unconditionally overrides the user name given in the connection
URI by the one found in ~/.ssh/config (if that does specify one for
the used host). If the SSH config file has a different user name,
we'll end up using the wrong name, which typically results in an
authentication failure or in Eclipse/EGit asking for a password for
the wrong user.
Unfortunately there is no way to prevent or circumvent this Jsch
behavior up front; it occurs already in the Session constructor at
com.jcraft.jsch.Session() and the Session.applyConfig() method. And
while there is a Session.setUserName() that would enable us to correct
this, that latter method has package visibility only.
So resort to reflection to invoke that setUserName() method to ensure
that Jsch uses the user name from the URI, if there is one.

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.

* stable-4.9:
PackInserter: Implement newReader()
Move some strings from DfsText to JGitText
FileRepository: Add pack-based inserter implementation
ObjectDirectory: Factor a method to close open pack handles
ObjectDirectory: Remove last modified check in insertPack
Change-Id: Ifc9ed6f5d8336bc978818a64eae122bceb933e5d
Applications that use ObjectInserters to create lots of individual
objects may prefer to avoid cluttering up the object directory with
loose objects. Add a specialized inserter implementation that produces a
single pack file no matter how many objects. This inserter is loosely
based on the existing DfsInserter implementation, but is simpler since
we don't need to buffer blocks in memory before writing to storage.
An alternative for such applications would be to write out the loose
objects and then repack just those objects later. This operation is not
currently supported with the GC class, which always repacks existing
packs when compacting loose objects. This in turn requires more
CPU-intensive reachability checks and extra I/O to copy objects from old
packs to new packs.
So, the choice was between implementing a new variant of repack, or not
writing loose objects in the first place. The latter approach is likely
less code overall, and avoids unnecessary I/O at runtime.
The current implementation does not yet support newReader() for reading
back objects.

GC explicitly handles the case where a new pack has the same name as an
existing pack due to it containing the exact same set of objects. In
this case, the pack passed to insertPack will have the same name as an
existing pack, but it will also almost certainly have a later mtime than
the existing pack.
The loop in insertPack tried to short-circuit when inserting a new pack,
to avoid walking more of the pack list than necessary. Unfortunately,
this means it will never get to the check for an identical name,
resulting in a duplicate entry for the same PackFile in the pack list.
Remove the short-circuit so that insertPack does not insert a duplicate
entry.

So far we follow OSGi semantic versioning [1] which says the following:
"A change in the second (minor) part of the version signals that the
change is backward compatible with consumers of the API package but not
with the providers of that API. That is, when the API package goes from
version 1.5 to 1.6 it is no longer compatible with a provider of that
API but consumers of that API are backward compatible with that API
package."
The change Ib5fbf17bdaf727bc5d0e106ce88f2620d9f87a6f broke EMF Compare
which subclasses ResolveMerger since we added a new parameter to the
protected ResolveMerger.processEntry() method. According to the above
cited OSGi semantic versioning this is ok, implementers should expect
that they break on minor version changes of the API they implement.
This change reintroduces the old processEntry() method in order to help
avoid breakage for existing EMF Compare versions which expect breakage
also for the implementer case only for major version change (in this
case from JGit 4.x to 5.x).
