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)

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.

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.

LargePackedWholeObject.openStream produces a stream that allows
reading a large object. This stream holds a DfsReader that takes care
of caching delta bases etc and in particular holds zlib Inflater for
use while reading the each delta in the packfile.
At DfsReader creation time, the Inflater is acquired from a global
InflaterCache to avoid initialization overhead in case there is an
existing Inflater available for reuse. When done with the Inflater,
the DfsReader is responsible for returning it to the cache for reuse.
The DfsReader is AutoClosable to remind the caller to close it and
release the Inflater when finished with it.
b0ac5f9c89 (LargePackedWholeObject:
Refactor to open DfsReader in try-with-resource, 2018-04-11) tried to
clarify the lifetime of the DfsReader but was too aggressive: when
this function returns, PackInputStream owns the DfsReader and is
already going to release it. Worse, the returned InflaterInputStream
holds a reference to the DfsReader's inflater, making releasing the
DfsReader not only unnecessary but unsafe.
The Inflater gets released into the InflaterCache's pool, to be
acquired by another caller that uses it concurrently with the
InflaterInputStream. This results in errors, such as

Most pkt-lines (data-pkts) have the form
pkt-len pkt-payload
where pkt-len is a string of 4 hexadecimal digits representing the
size in bytes of the pkt-line. Since this size includes the size of
the pkt-len, no data-pkt has a length less than 4.
A pkt-line with a length field less than 4 can thus be used for
other purposes. In Git protocol v1, the only such pkt-line was
flush-pkt = "0000"
which was used to mark the end of a stream. Protocol v2 (see
Documentation/technical/protocol-v2.txt in git.git) introduces a
second special pkt-line type:
delim-pkt = "0001"
used to mark the end of a section within a stream, for example to
separate capabilities from the content of a command.

The existing RefDatabase#getRefs abstract method (to be implemented by
ref database backends) has the following issues:
- It returns a map with a key (the name of the ref with the prefix
removed) which is potentially superfluous (it can be derived by the
caller if need be) and confusing (in that the prefix is removed).
- The prefix is required to end with a '/', but some backends (e.g.
reftable) have fast search by prefix regardless of what the last
character of the prefix is.
Add a new method #getRefsByPrefix that does not have these issues. This
is non-abstract with a default implementation that uses #getRefs (for
backwards compatibility), but ref database backends can reimplement it.
This also prepares for supporting "ref-prefix" in the "ls-refs" command
in the fetch-pack/upload-pack protocol v2, which does not require that
the prefix end with a '/'.

Various places on the client side of the push were creating unordered
maps and sets of ref names, resulting in ReceivePack processing commands
in an order other than what the client provided. This is normally not
problematic for clients, who don't typically care about the order in
which ref updates are applied to the storage layer.
However, it does make it difficult to write deterministic tests of
ReceivePack or hooks whose output depends on the order in which commands
are processed, for example if informational per-ref messages are written
to a sideband.[1]
Add a test that ensures the ordering of commands both internally in
ReceivePack and in the output PushResult.

Getting attributes of files on Windows is an expensive operation.
Windows stores file attributes in the directory, so they are
basically available "for free" when a directory is listed. The
implementation of Java's Files.walkFileTree() takes advantage of
that (at least in the OpenJDK implementation for Windows) and
provides the attributes from the directory to a FileVisitor.
Using Files.walkFileTree() with a maximum depth of 1 is thus a
good approach on Windows to get both the file names and the
attributes in one go.
In my tests, this gives a significant speed-up of FileTreeIterator
over the "normal" way: using File.listFiles() and then reading the
attributes of each file individually. The speed-up is hard to
quantify exactly, but in my tests I've observed consistently 30-40%
for staging 500 files one after another, each individually, and up
to 50% for individual TreeWalks with a FileTreeIterator.
On Unix, this technique is detrimental. Unix stores file attributes
differently, and getting attributes of individual files is not costly.
On Unix, the old way of doing a listFiles() and getting individual
attributes (both native operations) is about three times faster than
using walkFileTree, which is implemented in Java.
Therefore, move the operation to FS/FS_Win32 and call it from
FileTreeIterator, so that we can have different implementations
depending on the file system.
A little performance test program is included as a JUnit test (to be
run manually).
While this does speed up things on Windows, it doesn't solve the basic
problem of bug 532300: the iterator always gets the full directory
listing and the attributes of all files, and the more files there are
the longer that takes.

Teach UploadPack to advertise the filter capability and support a
"filter" line in the request, accepting blob sizes only, if the
configuration variable "uploadpack.allowfilter" is true. This feature is
currently in the "master" branch of Git, and as of the time of writing,
this feature is to be released in Git 2.17.
This is incomplete in that the filter-by-sparse-specification feature
also supported by Git is not included in this patch.
If a JGit server were to be patched with this commit, and a repository
on that server configured with RequestPolicy.ANY or
RequestPolicy.REACHABLE_COMMIT_TIP, a Git client built from the "master"
branch would be able to perform a partial clone.

The implementation of ObjectIdSerializer, added in change I7599cf8bd,
is not equivalent to the original implementation in Gerrit [1].
The Gerrit implementation provides separate methods to (de)serialize
instances of ObjectId that are known to be non-null. In these methods,
no "marker" is written to the stream. Replacing Gerrit's implementation
with ObjectIdSerializer [2] broke persistent caches because it started
writing markers where they were not expected [3].
Since ObjectIdSerializer is included in JGit 4.11 we can't change the
existing #write and #read methods. Keep those as-is, but extend the
Javadoc to clarify that they support possibly null ObjectId instances.
Add new methods #writeWithoutMarker and #readWithoutMarker to support
the cases where the ObjectId is known to be non-null and the marker
should not be written to the serialization stream.
Also:
- Replace the hard-coded `0` and `1` markers with constants that can
be linked from the Javadocs.
- Include the marker value in the "Invalid flag before ObjectId"
exception message.

This is based on the ObjectIdSerialization class written by Shawn Pearce
for the Gerrit Code Review project in 2009 [1]. As mentioned in the
commit message there, it should be part of core JGit.
This implementation is slightly different to Shawn's version. Rather
than having separate methods for null/non-null ids, single methods are
implemented with @Nullable annotations.

If we give Jsch access to the ssh config file, we must _not_ resolve
the host name from the alias. Instead we must give the alias (i.e.,
the host name as is in the URI) to Jsch, so that it finds the same
ssh config entry.
Otherwise if the hostname in the URI, which is taken as an alias in
ssh config ("Host" line), is unequal to the "Hostname" line, and
there happens to be another ssh config entry with that translated
host name as alias, Jsch will pick up that second entry, and we end
up with a strange mixture of both.

Android an Chrome have several repos with >300k refs. We sometimes see
negotiations of >100k rounds. This change provides a "minimal negotiation"
feature on the client side that limits how many "have" lines the client
sends. The client extracts the current SHA-1 values for the refs in its
wants set, and terminates negotiation early when all of those values have
been sent as haves. If a new branch is being fetched then that set will
be empty and the client will terminate after current default minimum
of two rounds.
This feature is gated behind a "fetch.useminimalnegotiation" configuration
flag, which defaults to false.

conflicts inside .gitmodules files. That's OK: git.git doesn't
either. Users can resolve the conflict themselves and then commit
the merge.
Previously, jgit would crash when attempting to merge conflicting
submodule changes. Even if there was no conflict, after a merge which
adds submodules, the repository would have been missing empty
directories for newly-added submodules.
This patch fixes the crash, and adds the empty directories where
necessary. It ensures that the index is in a conflicted state when
submodule changes conflict.

Commit fc7d407 corrected line endings for working tree files resulting
from merges when CRLF translations are to be done. However, that also
resulted in the file content being put as-is into the index, which is
wrong. The index must contain the file content with reverse CRLF
translations applied.
With core.autocrlf=true, the working tree file should have CR-LF, but
the index blob must still contain only LF.
Fix this oversight and apply the inverse translation when updating the
index, similar to what is done in AddCommand.

checkout can take quite some time on larger repositories. To avoid

PackInserter: Ensure objects are written at the end of the pack
ObjectInserter: Add warning about mixing read-back with writes
Change-Id: I308e7c1c6b72e8d4d9b5d0f4f51e9815fc92d7d7
When interleaving reads and writes from an unflushed pack, we forgot to
reset the file pointer back to the end of the file before writing more
new objects. This had at least two unfortunate effects:
* The pack data was potentially corrupt, since we could overwrite
previous portions of the file willy-nilly.
* The CountingOutputStream would report more bytes read than the size
of the file, which stored the wrong PackedObjectInfo, which would
cause EOFs during reading.
We already had a test in PackInserterTest which was supposed to catch
bugs like this, by interleaving reads and writes. Unfortunately, it
didn't catch the bug, since as an implementation detail we always read a
full buffer's worth of data from the file when inflating during
readback. If the size of the file was less than the offset of the object
we were reading back plus one buffer (8192 bytes), we would completely
accidentally end up back in the right place in the file.
So, add another test for this case where we read back a small object
positioned before a large object. Before the fix, this test exhibited
exactly the "Unexpected EOF" error reported at crbug.com/gerrit/7668.

Previously, Config was using the same method for both escaping and
parsing subsection names and config values. The goal was presumably code
savings, but unfortunately, these two pieces of the git config format
are simply different.
In git v2.15.1, Documentation/config.txt says the following about
subsection names:
"Subsection names are case sensitive and can contain any characters
except newline (doublequote `"` and backslash can be included by
escaping them as `\"` and `\\`, respectively). Section headers cannot
span multiple lines. Variables may belong directly to a section or to
a given subsection."
And, later in the same documentation section, about values:
"A line that defines a value can be continued to the next line by
ending it with a `\`; the backquote and the end-of-line are stripped.
Leading whitespaces after 'name =', the remainder of the line after
the first comment character '#' or ';', and trailing whitespaces of
the line are discarded unless they are enclosed in double quotes.
Internal whitespaces within the value are retained verbatim.
Inside double quotes, double quote `"` and backslash `\` characters
must be escaped: use `\"` for `"` and `\\` for `\`.
The following escape sequences (beside `\"` and `\\`) are recognized:
`\n` for newline character (NL), `\t` for horizontal tabulation (HT,
TAB) and `\b` for backspace (BS). Other char escape sequences
(including octal escape sequences) are invalid."
The main important differences are that subsection names have a limited
set of supported escape sequences, and do not support newlines at all,
either escaped or unescaped. Arguably, it would be easy to support
escaped newlines, but C git simply does not:
$ git config -f foo.config $'foo.bar\nbaz.quux' value
error: invalid key (newline): foo.bar
baz.quux
I468106ac was an attempt to fix one bug in escapeValue, around leading
whitespace, without having to rewrite the whole escaping/parsing code.
Unfortunately, because escapeValue was used for escaping subsection
names as well, this made it possible to write invalid config files, any
time Config#toText is called with a subsection name with trailing
whitespace, like {foo }.
Rather than pile hacks on top of hacks, fix it for real by largely
rewriting the escaping and parsing code.
In addition to fixing escape sequences, fix (and write tests for) a few
more issues in the old implementation:
* Now that we can properly parse it, always emit newlines as "\n" from
escapeValue, rather than the weird (but still supported) syntax with a
non-quoted trailing literal "\n\" before the newline. In addition to
producing more readable output and matching the behavior of C git,
this makes the escaping code much simpler.
* Disallow '\0' entirely within both subsection names and values, since
due to Unix command line argument conventions it is impossible to pass
such values to "git config".
* Properly preserve intra-value whitespace when parsing, rather than
collapsing it all to a single space.

When we are cloning we have no refs at all yet, and there cannot
(or at least should not) be any other thread doing something with
refs yet.
Locking loose refs is thus not needed, since there are no loose
refs yet and nothing should be trying to create them concurrently.
Let's skip the whole loose ref locking when we are cloning a repository.
As a result, JGit will write the refs directly to the packed-refs
file, and will not create the refs/remotes/ directories nor the
lock files underneath when cloning and packed refs are used. Since
no lock files are created, any problems on case-insensitive file
systems with tag or branch names that differ only in case are avoided
during cloning.
Detect if we are cloning based on the following heuristics:
* HEAD is a dangling symref
* There is no loose ref
* There is no packed-refs file
Note, however, that there may still be problems with such tag or
branch names later on. This is primarily a five-minutes-past-twelve
stop-gap measure to resolve the referenced bug, which affects the
Oxygen.2 release.

There is no point in calling back to the RemoteReader to resolve a

When a GC operation is interrupted, temporary packs and indexes can be
left on the pack folder. In big, busy repositories this can lead to
significant amounts of wasted disk space if this interruption is done
with a certain frequency.
Remove stale temporary packs and indexes at the end of the GC process so
they do not accumulate. To avoid interfering with a possible concurrent
JGit GC process in the same repository, only delete temporary files that
are older than one day.

When running on NFS there was a chance that JGits LockFile
semantic is broken because File#createNewFile() may allow
multiple clients to create the same file in parallel. This
change provides a fix which is only used when the new config
option core.supportsAtomicCreateNewFile is set to false. The
default for this option is true. This option can only be set in the
global or the system config file. The repository config file is not
taken into account in this case.
If the config option core.supportsAtomicCreateNewFile is true
then File#createNewFile() is trusted and the behaviour doesn't
change.
But if core.supportsAtomicCreateNewFile is set to false then after
successful creation of the lock file a hardlink to that lock file is
created and the attribute nlink of the lock file is checked to be 2. If
multiple clients manage to create the same lock file nlink would be
greater than 2 showing the error.
This expensive workaround is described in

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.

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

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.

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.
Change-Id: I2074418f4e65853b7113de5eaced3a6b037d1a17
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).

Do tilde replacement for values from the ssh config file that are
file names in all cases to make sure that they are already replaced
when Jsch tries to get the values.
Previously, OpenSshConfig did tilde replacement only for the
IdentityFile in the JGit-facing "Host" interface and left the
replacement in the Jsch-facing "Config" interface to Jsch.
But on Windows the JGit notion of what should be used to replace the
tilde differs from Jsch's replacement. Jsch always replaces the tilde
by the value of the system property "user.home", whereas JGit also
considers some environment variables like %HOME%. This can lead to
rather surprising failures as in the case of bug 526175 where
%HOME% != user.home.
Prior to commit 9d24470 (i.e.,prior to JGit 4.9.0) this problem never
occurred because Jsch was completely unaware of the ssh config file
and all host and IdentityFile handling happened exclusively in JGit.

The ReflogWriter constructor just took a Repository and called
getDirectory() on it to figure out the reflog dirs, but not all
Repository instances use this storage format for reflogs, so it's
incorrect to attempt to use ReflogWriter when there is not a
RefDirectory directly involved. In practice, ReflogWriter was mostly
only used by the implementation of RefDirectory, so enforcing this is
mostly just shuffling around calls in the same internal package.
The one exception is StashDropCommand, which writes to a reflog lock
file directly. This was a reasonable implementation decision, because
there is no general reflog interface in JGit beyond using
(Batch)RefUpdate to write new entries to the reflog. So to implement
"git stash drop <N>", which removes an arbitrary element from the
reflog, it's fair to fall back to the RefDirectory implementation.
Creating and using a more general interface is well beyond the scope of
this change.
That said, the old behavior of writing out the reflog file even if
that's not the reflog format used by the given Repository is clearly
wrong. Fail fast in this case instead.

When a https connection could not be established because the SSL
handshake was unsuccessful, TransportHttp would unconditionally
throw a TransportException.
Other https clients like web browsers or also some SVN clients
handle this more gracefully. If there's a problem with the server
certificate, they inform the user and give him a possibility to
connect to the server all the same.
In git, this would correspond to dynamically setting http.sslVerify
to false for the server.
Implement this using the CredentialsProvider to inform and ask the
user. We offer three choices:
1. skip SSL verification for the current git operation, or
2. skip SSL verification for the server always from now on for
requests originating from the current repository, or
3. always skip SSL verification for the server from now on.
For (1), we just suppress SSL verification for the current instance of
TransportHttp.
For (2), we store a http.<uri>.sslVerify = false setting for the
original URI in the repo config.
For (3), we store the http.<uri>.sslVerify setting in the git user
config.
Adapt the SmartClientSmartServerSslTest such that it uses this
mechanism instead of setting http.sslVerify up front.
Improve SimpleHttpServer to enable setting it up also with HTTPS
support in anticipation of an EGit SWTbot UI test verifying that
cloning via HTTPS from a server that has a certificate that doesn't
validate pops up the correct dialog, and that cloning subsequently
proceeds successfully if the user decides to skip SSL verification.

Git has a rather elaborate mechanism to specify HTTP configuration
options per URL, based on pattern matching the URL against "http"
subsection names.[1] The URLs used for this matching are always the
original URLs; redirected URLs do not participate.
* Scheme and host must match exactly case-insensitively.
* An optional user name must match exactly.
* Ports must match exactly after default ports have been filled in.
* The path of a subsection, if any, must match a segment prefix of
the path of the URL.
* Matches with user name take precedence over equal-length path
matches without, but longer path matches are preferred over
shorter matches with user name.
Implement this for JGit. Factor out the HttpConfig from TransportHttp
and implement the matching and override mechanism.
The set of supported settings is still the same; JGit currently
supports only followRedirects, postBuffer, and sslVerify, plus the
JGit-specific maxRedirects key.
Add tests for path normalization and prefix matching only on segment
separators, and use the new mechanism in SmartClientSmartServerSslTest
to disable sslVerify selectively for only the test server URLs.
Compare also bug 374703 and bug 465492. With this commit it would be
possible to set sslVerify to false for only the git server using a
self-signed certificate instead of having to switch it off globally
via http.sslVerify.

With atomic ref updates using packed refs, JGit did not fire a
RefsChangedEvent. This resulted in a user-visible regression in
EGit: the UI would not update after a "Fetch from upstream...".
Presumably it would also make Gerrit miss out on ref changes?
Strengthen the BatchRefUpdateTest by also asserting the expected
number of RefsChangedEvents, and ensure modCnt is incremented in
RefDirectory.commitPackedRefs() when refs really changed (as opposed
to some internal housekeeping operation, such as packing loose refs).

Much of the time the caller can specify a RefSpec succinctly using a
string, and doesn't care about calling setters. Add a convenience method
for this case, and use it where applicable in JGit core.

An application can choose to invoke setAdvertisedRefs multiple times,
for example several AdvertiseRefsHook installed in a chain. Each of
these invocations populates the advertisedHaves collection with the
unique set of ObjectIds.
This can lead to a server over-advertising with ".have" lines if the
first hook pushes in a lot of references, and the second hook filters
this to a subset. ReceivePack will advertise the unique objects from
the first hook using ".have" lines, which may lead to a huge
advertisement sent to the client.
This can also contribute to a very slow connectivity check after the
pack is parsed as ReceivePack calls markUninteresting on every commit
in advertisedHaves. This may require expanding a lot of subtrees to
mark all trees as uninteresting as well. On a very big repository
this can lead to a many-second stall.
Clear the advertisedHaves collection any time the refs are updated.
Add a test to verify the correct set of objects was sent.

If a ReftableConfig has been supplied by the caller, write out a
reftable as a sibling of the the GC pack, alongside the heads.
To bootstrap from a non-reftable system, the refs are read from the
DfsRefDatabase if no GC reftables are present. Its assumed the
references are fully current, and do not need to be merged with any
other reftables. Any non-GC reftables will be pruned at the end of
the GC cycle, just like any packs that were replaced.
If a GC reftable is present, all existing reftables are compacted, and
references from DfsRefDatabase are only used to seed the packer. Its
assumed these are consistent with each other.

Sun's Java 5, 6, 7 implementation had a bug [1] where a Reference can be
enqueued and dequeued twice on the same reference queue due to a race
condition within ReferenceQueue.enqueue(Reference).
This bug was fixed for Java 8 [2] hence remove the workaround.

While parsing .gitmodules, the name of the submodule subsection is
purely arbitrary: it frequently is the path of the submodule, but
there's no requirement for it to be. By building a map of paths to
the section name in .gitmodules, we can more accurately return
the submodule URL.

* changes:
DfsFsck: reduce memory usage during verifyIndex
DfsFsck: refactor pack verify into its own method
DfsFsck: run connectivity check pass exactly once
Don't convert a lot of ObjectId to String stored in generic
java.util.HashSet. This is a very expensive way to store objects.
Instead rely on "this" from the FsckPackParser to lookup information
about the objects in this pack file, which lets the verify code avoid
sorting the object list.
Use ObjectIdOwnerMap, which is the most efficient format JGit has
for storing lots of objects.

This simplifies the logic about allocation of the DfsReader, and
clarifies the code considerably by using smaller scopes with less

The simpler algorithm is to load all branch tips into an ObjectWalk
and run that walk exactly once. This avoids redoing work related to
parsing and considering trees reused across side branches.
Move the connectivity check into its own helper method. This moves it
left one level of identation, and makes it easier to fit the method's
logic with less line wrapping.
Add a "Counting objects..." progress monitor around this phase. Its
what is used when a server receives a push and is also trying to
verify the client sent all required objects.

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.

- 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

Some repositories can have a policy that do not accept certain blobs. To
check if the incoming pack file contains such blobs, ObjectChecker can
be used. However, this ObjectChecker is not called by PackParser if the
blob is stored as a whole. This is because the object can be so large
that it doesn't fit in memory.
This change introduces BlobObjectChecker. This interface takes chunks of
a blob instead of the entire object. ObjectChecker can optionally return
a BlobObjectChecker. This won't change existing ObjectChecker
implementation; existing implementation continues to receive deltified
blob objects only.
