The canonical implementation also doesn't. Compare current
code in remote.c, function get_stale_heads_cb.[1] Not handling
symrefs in this case was introduced in canonical git in [2]
in 2008.

Callers of getAllRefs that only iterate over the `values()` of the
returned map can be trivially fixed to call getRefDatabase().getRefs()
instead.
Only fix those where the calling method is already declared to throw
IOException, to avoid potential API changes.

Callers should instead use getRefDatabase().getRefs(), which does not
swallow the IOException.
Replace @link with @code in the Javadoc of FileRepository, since linking
to the deprecated method causes an error:
Javadoc: The method getAllRefs() from the type Repository is deprecated
Existing callers of the deprecated method are not adapted in this commit
because many of them require more refactoring. They will be done in
separate follow-up commits.

doesn't swallow the IOException.
Adapt all trivial callers to user the alternative.
DescribeCommand still uses the deprecated method and is not adapted in
this change since it will require more refactoring to add handling of
the IOException.

This means less cognitive overhead for both implementors and callers,
since this way we can guarantee that they are always synonyms for
RefDatabase#exactRef and RefDatabase#findRef, respectively.

Make FileTreeIterator not enter ignored directories by default. We
only need to enter ignored directories if we do some operation against
git, and there is at least one tracked file underneath an ignored
directory.
Walking ignored directories should be avoided as much as possible as
it is a potential performance bottleneck. Some projects have a lot of
files or very deep hierarchies in ignored directories; walking those
may be costly (especially so on Windows). See for instance also bug
500106.
Provide a FileTreeIterator.setWalkIgnoredDirectories() operation to
force the iterator to iterate also through otherwise ignored
directories. Useful for tests (IgnoreNodeTest, CGitIgnoreTest), or
to implement things like "git ls-files --ignored".
Add tests in DirCacheCheckoutTest, and amend IndexDiffTest to test a
little bit more.

Declare Repository#notifyIndexChanged() final and
Repository#notifyIndexChanged(boolean) abstract to force implementors
to switch to overriding the latter method. This makes Repository less
error-prone to extend since implementors no longer need to remember to
override one of those two methods.

e9e150fdd2 (Store in IndexChangedEvent if it was caused by JGit
itself, 2018-05-13) modified Repository#notifyIndexChanged to take a
boolean argument to indicate whether the index change happened under
the current process's control or externally, for use by EGit. In
other words, the function signature changed from
public abstract void notifyIndexChanged();
to
public abstract void notifyIndexChanged(boolean internal);
Callers outside JGit itself notifying a Repository about index changes
are expected to be rare, so this is not very disruptive to them. In
most cases they would be notifying about changes that they made
themselves, so treating their notifyIndexChanged() calls as
notifyIndexChanged(true) should be relatively safe.
Implementors have the opposite problem: adding the new "abstract void
notifyIndexChanged(boolean)" method means they are obligated to
override it. Add a default implementation that calls their existing
override of notifyIndexChanged() to make their migration easier.
The main downside is that authors of new Repository subclasses that
do not realize they need to override notifyIndexChanged would end up
with a default implementation which calls notifyIndexChanged(true),
in turn calling notifyIndexChanged() again and so on, resulting in
StackOverflowException. Add an implementors' note to the class
Javadoc to avoid this issue. A followup commit will force
implementors to adapt to the new API by changing the methods to
@Deprecated
public final void notifyIndexChanged() {
notifyIndexChanged(true);
}
public abstract void notifyIndexChanged(boolean internal);

Refs are not advertised as part of the protocol v2 capability
advertisement. Don't call AdvertiseRefsHook.
Noticed because many implementations of AdvertiseRefsHook read all
refs in order to call UploadPack#setAdvertisedRefs, causing the
capability advertisement to be as slow as a v0 ref advertisement with
some RefDatabase implementations.
Such an AdvertiseRefsHook is of dubious utility (a better place to
determine which refs are advertised is in the RefDatabase
implementation itself, as in Gerrit), but at any rate since it's not
bringing about any benefit here, we can skip the hook call.
TODO:
- call an appropriate hook instead (https://bugs.eclipse.org/534847)
- add tests

With this patch, a server spawned by "jgit daemon" can be accessed using
protocol v2 from a Git client that supports it (for example, "git" with
the appropriate patches). This is only activated if the repository's
config has "protocol.version" be 2.
This required a change to the package-private #execute methods in
DaemonService to allow passing of extra parameters.
This has been tested with a patched Git.

Add support for the "include-tag" parameter in the "fetch" command in
the fetch-pack/upload-pack protocol v2.
In order to determine which tags to include, only objects pointed to by
refs starting with "refs/tags/" are checked. This restriction is for
performance reasons and to match the behavior of Git (see add_ref_tag()
in builtin/pack-objects.c).

When OPTION_INCLUDE_TAG is set, UploadPack#sendPack uses the #refs
instance variable as a source of information of tags. A subsequent patch
will need to supply this information to #sendPack without
modifying #refs, so refactor #sendPack to take in this information
through a parameter instead.
Note that prior to this patch, #refs was used twice in #sendPack: once
to generate the argument to PackWriter#setTagTargets, and once to
determine if any tags need to be included in the packfile. This patch
only updates the latter use, since the former is meant not only for
"true" tag targets but any object that should be hoisted earlier during
packing (see the documentation of PackWriter#setTagTargets).
This patch does not introduce any functionality change.

On a local non-NFS filesystem the .git/config file will be orphaned if
it is replaced by a new process while the current process is reading the
old file. The current process successfully continues to read the
orphaned file until it closes the file handle.
Since NFS servers do not keep track of open files, instead of orphaning
the old .git/config file, such a replacement on an NFS filesystem will
instead cause the old file to be garbage collected (deleted). A stale
file handle exception will be raised on NFS clients if the file is
garbage collected (deleted) on the server while it is being read. Since
we no longer have access to the old file in these cases, the previous
code would just fail. However, in these cases, reopening the file and
rereading it will succeed (since it will open the new replacement file).
Since retrying the read is a viable strategy to deal with stale file
handles on the .git/config file, implement such a strategy.
Since it is possible that the .git/config file could be replaced again
while rereading it, loop on stale file handle exceptions, up to 5 extra
times, trying to read the .git/config file again, until we either read
the new file, or find that the file no longer exists. The limit of 5 is
arbitrary, and provides a safe upper bounds to prevent infinite loops
consuming resources in a potential unforeseen persistent error
condition.
