Swallowing intermittent errors and trying to recover from them
makes JGit's behavior hard to predict and difficult to debug.
Propagate the errors instead. This doesn't violate JGit's usual
backward compatibility promise for clients because in these
contexts an IOException indicates either repository corruption or
a true I/O error. Let's consider these cases one at a time.
In the case of repository corruption, falling back e.g. to an empty
set of refs or a missing ref will not serve a caller well. The
fallback does not indicate the nature of the corruption, so they are
not in a good place to recover from the error. This is analogous to
Git, which attempts to provide sufficient support to recover from
corruption (by ensuring commands like "git branch -D" cope with
corruption) but little else.
In the case of an I/O error, the best we can do is to propagate the
error so that the user sees a dialog and has an opportunity to try
again. As in the corruption case, the fallback behavior does not
provide enough information for a caller to rely on the current error
handling, and callers such as EGit already need to be able to handle
runtime exceptions.
To be conservative, keep the existing behavior for the deprecated
Repository#peel method. In this example, the fallback behavior is to
return an unpeeled ref, which is distinguishable from the ref not
existing and should thus at least be possible to debug.

Don't use the ~/.ssh directory as cache key for the key provider
but the configured paths of the default keys. Otherwise changes
in that list of paths are not picked up.
This is in particular a problem for EGit, where the user can modify
this list of keys interactively in the preferences. Without this
change, Eclipse needs to be restarted to pick up such changes.

Better to use ObjectDatabase#has, which throws IOException to report

A checkout done directly after cloning (the "initial
checkout") has a different semantic as a default
checkout. That is defined in the documentation of
"git read-tree" [1]. JGit was detecting that it is
doing an initial checkout differently from native
git: jgit used to check that the index is empty
but native git required that the index file does
not exist [2]. Teach JGit to behave like native
git.

Using findRef instead of getRef makes it clearer that the caller wants
to search for the ref in the search path, instead of looking for a ref
that exactly matches the input.
This change introduces the new findRef method and deprecates getRef.
It updates Repository#findRef to use the new method, ensuring some
test coverage. Other callers will be updated in followup changes.
A nice side effect of introducing the new findRef method is that it is
final and based on firstExactRef, so implementers can focus on
implementing the latter efficiently and do not have to carefully write
custom path search code respecting SEARCH_PATH.

Override exactRef(String...) and firstExactRef(String...) with
implementations specific to FileRepository.
The specialized implementations are similar to the generic ones from
RefDatabase, but because these use readRef directly instead of
exactRef, they only need to call fireRefsChanged once.
This will allow replacing RefDirectory#getRef with a generic
implementation that uses firstExactRef without hurting performance.

getRef and exactRef can produce recoverable exceptions --- for
example, a corrupt loose ref that cannot be parsed. If readRef was
called and updated looseRefs in the process, RefsChangedEvent should
still be fired.
Noticed while improving the implementation of getRef. This commit
only affects exactRef and getRef. Other methods might be similarly
skipping firing RefsChangedEvent in their error handling code, and
this change does not fix them.

Both getRef and exactRef look for a ref or pseudoref in the $GIT_DIR
directory, with careful error handling to handle non-refs like
.git/config.
Avoid the duplication by factoring out a helper that takes care of
this. This should make the code easier to understand and manipulate.

In DFS implementations the reference table can fall out of sync, but
it is not possible to check this situation in the current API.
Add a property to the Refs indicating the order of its updates. This
version is set only by RefDatabase implementations that support
versioning (e.g reftable based).
Caller is responsible to check if the reference db creates versioned
refs before accessing getUpdateIndex(). E.g:
Ref ref = refdb.exactRef(...);
if (refdb.hasVersioning()) {
ref.getUpdateIndex();
}

When a server sends a ref advertisement using protocol v2 it contains
lines other than ref names and sha1s. Attempting to get the sha1 out
of such a line using the substring method can result in a SIOOB error
when it doesn't actually contain the sha1 and ref name.
Add a check that the line is of the expected length, and subsequently
that the extracted object id is valid, and if not throw an exception.

UploadPack has a setTransferConfig method which allows to set the
transfer config, however since the constructors of TransferConfig
have the default package visibility it is not possible for any
application using UploadPack, for example Gerrit, to actually set
a transfer config.
Make the constructors public. This is consistent with the public
constructors for example on PackConfig.
