Handle more cases for file mode changes. Especially make sure that the
following cases are handled correctly.
Case 1)
An entry in the working tree, HEAD tree, and merge tree have
different modes and different content.
Prior Outcome:
Dirty working tree content is replaced and file mode
changes are lost.
New Outcome:
Conflict is generated.
Case 2)
An entry in the index and merge tree have the same content
but different modes but both modes are file type modes.
Prior Outcome:
File mode in working tree is not updated and the working
directory is dirty.
New Outcome:
Index is updated and the working directory is clean.

When ResolveMerger finds a path where it has to do a content merge it
will try the content merge and if that succeeds it'll add the newly
produced content to the index. For the FileMode of this new index entry
it blindly copies the FileMode it finds for that path in the common base
tree. If by chance the common base tree does not contain this path it'll
try to add FileMode 0 (MISSING) to the index.
One could argue that this can't happen: how can the ResolveMerger
successfully (with no conflicts) merge two contents if there is no
common base? This was due to another bug in ResolveMerger. It failed to
find out that for two files which differ only in the FileMode (e.g. 644
vs. 755) it should not try a content merge.

ReceivePack (and PackParser) can be configured with the
maxObjectSizeLimit in order to prevent users from pushing too large
objects to Git. The limit check is applied to all object types
although it is most likely that a BLOB will exceed the limit. In all
cases the size of the object header is excluded from the object size
which is checked against the limit as this is the size of which a BLOB
object would take in the working tree when checked out as a file.
When an object exceeds the maxObjectSizeLimit the receive-pack will
abort immediately.
Delta objects (both offset and ref delta) are also checked against the
limit. However, for delta objects we will first check the size of the
inflated delta block against the maxObjectSizeLimit and abort
immediately if it exceeds the limit. In this case we even do not know
the exact size of the resolved delta object but we assume it will be
larger than the given maxObjectSizeLimit as delta is generally only
chosen if the delta can copy more data from the base object than the
delta needs to insert or needs to represent the copy ranges. Aborting
early, in this case, avoids unnecessary inflating of the (huge) delta
block.
Unfortunately, it is too expensive (especially for a large delta) to
compute SHA-1 of an object that causes the receive-pack to abort.
This would decrease the value of this feature whose main purpose is to
protect server resources from users pushing huge objects. Therefore
we don't report the SHA-1 in the error message.

The DfsReader must offer every representation of an object that
exists on the local repository when PackWriter asks for them. This
is necessary to identify objects in the thin pack part that are also
in the cached pack that will be appended onto the end of the stream.
Without looking at all alternatives, PackWriter may pack the same
object twice (once in the thin section, again in the cached base
pack). This may cause the command line C version to go into an
infinite loop when repacking the resulting repository, as it may see
a delta chain cycle with one of those duplicate copies of the object.
Previously the DfsReader tried to avoid looking at packs that it
might not care about, but this is insufficient, as all versions
must be considered during pack generation.
Change-Id: Ibf4a3e8ea5c42aef16404ffc42a5781edd97b18e
Consider two objects A->B where A uses B as a delta base, and these
are in the same source pack file ordered as "A B".
If cached packs is enabled and B is also in the cached pack that
will be appended onto the end of the thin pack, and both A, B are
supposed to be in the thin pack, PackWriter must consider the fact
that A's base B is an edge object that claims to be part of the
new pack, but is actually "external" and cannot be written first.
If the object reuse system considered B candidates fist this bug
does not arise, as B will be marked as edge due to it existing in
the cached pack. When the A candidates are later examined, A sees a
valid delta base is available as an edge, and will not later try to
"write base first" during the writing phase.
However, when the reuse system considers A candidates first they
see that B will be in the outgoing pack, as it is still part of
the thin pack, and arrange for A to be written first. Later when A
switches from being in-pack to being an edge object (as it is part
of the cached pack) the pointer in B does not get its type changed
from ObjectToPack to ObjectId, so B thinks A is non-edge.
We work around this case by also checking that the delta base B
is non-edge before writing the object to the pack. Later when A
writes its object header, delta base B's ObjectToPack will have
an offset == 0, which makes isWritten() = false, and the OBJ_REF
delta format will be used for A's header. This will be resolved by
the client to the copy of B that appears in the later cached pack.

Annotated tags are relatively rare and currently are scheduled in a
pack file near the commits, decreasing the time it takes to resolve
client requests reading tags as part of a history traversal.
Putting them first before the commits allows the storage system to
page in the tag area, and have it relatively hot in the LRU when
the nearby commit area gets examined too. Later looking at the
tree and blob data will pollute the cache, making it more likely
the tags are not loaded and would require file IO.

Memory usage is dominated by three terms:
- The maximum memory allocated to each delta window.
- The maximum size of a single file held in memory during delta search.
- ObjectToPack instances owned by the writer.
For the first two terms, rather than doing complex instrumentation of
the DeltaWindows, we just overestimate based on the config parameters
(though we may underestimate if the maximum size is not set).
For the ObjectToPack instances, we do some rough byte accounting of the
underlying Java object representation.

This includes merging ReadTreeTest into DirCacheCheckoutTest and
converting IndexDiffTest to use DirCache only. The GitIndex specific
T0007GitIndex test remains.
GitIndex is deprecated. Let us speed up its demise by focusing the
DirCacheCheckout tests to using DirCache instead.
This also add explicit deprecation comments to methods that depend
on GitIndex in Repository and TreeEntry. The latter is deprecated in
itself.

Any RuntimeException or Error in this block will leave the lock
held by the caller thread, which can later result in deadlock or
just cache requests hanging forever because they cannot get to

even though a RuntimeException or Error should never happen in
any of these code paths.

The cache starts with a single empty Ref that has no data, as the
clock list does not support being empty. When this Ref is removed,
the size has to be decremented from the associated DfsPackKey,
which was previously null. Make it always be non-null.

In practice the DHT storage layer has not been performing as well as
large scale server environments want to see from a Git server.
The performance of the DHT schema degrades rapidly as small changes
are pushed into the repository due to the chunk size being less than
1/3 of the pushed pack size. Small chunks cause poor prefetch
performance during reading, and require significantly longer prefetch
lists inside of the chunk meta field to work around the small size.
The DHT code is very complex (>17,000 lines of code) and is very
sensitive to the underlying database round-trip time, as well as the
way objects were written into the pack stream that was chunked and
stored on the database. A poor pack layout (from any version of C Git
prior to Junio reworking it) can cause the DHT code to be unable to
enumerate the objects of the linux-2.6 repository in a completable
time scale.
Performing a clone from a DHT stored repository of 2 million objects
takes 2 million row lookups in the DHT to locate the OBJECT_INDEX row
for each object being cloned. This is very difficult for some DHTs to
scale, even at 5000 rows/second the lookup stage alone takes 6 minutes
(on local filesystem, this is almost too fast to bother measuring).
Some servers like Apache Cassandra just fall over and cannot complete
the 2 million lookups in rapid fire.
On a ~400 MiB repository, the DHT schema has an extra 25 MiB of
redundant data that gets downloaded to the JGit process, and that is
before you consider the cost of the OBJECT_INDEX table also being
fully loaded, which is at least 223 MiB of data for the linux kernel
repository. In the DHT schema answering a `git clone` of the ~400 MiB
linux kernel needs to load 248 MiB of "index" data from the DHT, in
addition to the ~400 MiB of pack data that gets sent to the client.
This is 193 MiB more data to be accessed than the native filesystem
format, but it needs to come over a much smaller pipe (local Ethernet
typically) than the local SATA disk drive.
I also never got around to writing the "repack" support for the DHT
schema, as it turns out to be fairly complex to safely repack data in
the repository while also trying to minimize the amount of changes
made to the database, due to very common limitations on database
mutation rates..
This new DFS storage layer fixes a lot of those issues by taking the
simple approach for storing relatively standard Git pack and index
files on an abstract filesystem. Packs are accessed by an in-process
buffer cache, similar to the WindowCache used by the local filesystem
storage layer. Unlike the local file IO, there are some assumptions
that the storage system has relatively high latency and no concept of
"file handles". Instead it looks at the file more like HTTP byte range
requests, where a read channel is a simply a thunk to trigger a read
request over the network.
The DFS code in this change is still abstract, it does not store on
any particular filesystem, but is fairly well suited to the Amazon S3
or Apache Hadoop HDFS. Storing packs directly on HDFS rather than
HBase removes a layer of abstraction, as most HBase row reads turn
into an HDFS read.
Most of the DFS code in this change was blatently copied from the
local filesystem code. Most parts should be refactored to be shared
between the two storage systems, but right now I am hesistent to do
this due to how well tuned the local filesystem code currently is.

Since we replaced GitIndex by DirCache JGit didn't fire
IndexChangedEvents anymore. For EGit this still worked with a high
latency since its RepositoryChangeScanner which is scheduled to
run each 10 seconds fires the event in case the index changes.
This scanner is meant to detect index changes induced by a different
process e.g. by calling "git add" from native git.
When the index is changed from within the same process we should fire
the event synchronously. Compare the index checksum on write to index
checksum when index was read earlier to determine if index really
changed. Use IndexChangedListener interface to keep DirCache decoupled
from Repository.

The checkout command was producing an inconsistent state of the index
which even confuses native git. The content sha1 of the touched index
entries was updated, but the length and the filemode was not updated.
Later in coding the index entries got automatically corrected (through
Dircache.checkoutEntry()) but the correction was after persisting the
index to disk. So, the correction was lost and we ended up with an index
where length and sha1 don't fit together.
A similar problem is fixed with "lastModified" of DircacheEntry. When
checking out a path without specifying an explicit commit (you want to
checkout what's in the index) the index was not updated regarding
lastModified. Readers of the index will think the checked-out
file is dirty because the file has a younger lastmodified then what's
in the index.

Add a TransportConfigCallback parameter to JGit API commands, to allow
consumers of the JGit command API to perform custom Transport configuration
that would be otherwise difficult to anticipate & expose on the API command
builders.
My specific use-case is configuring additional properties on SshTransport
- I need to take over the SshSessionFactory used by the transport. Using
TransportConfigCallback I can simply do this (rather than reimplement the
API command classes):
public void configure(Transport tn) {
if (tn instanceof SshTransport) {
((SshTransport) tn).setSshSessionFactory(factoryProvider.get());
}
}
Adding an explicit setSshSessionFactory() method to the JGit command
classes would bloat the API. Also, creating the replacement
SshSessionFactory is unnecessary if the transport is not SSH, but the type
of the Transport is only known once the remote has been resolved and the
URI parsed - consequently it makes sense to perform this step in a
callback, where the transport instance can be inspected to determine if
it's of a relevant type.
A note about where this leaves the API - there are now 4 commands:
CloneCommand
PullCommand
FetchCommand
PushCommand
-that share 3 identical transport-related parameters:
timeout
credentialsProvider
transportConfigurator
I think there's potential for introducing an interface or val-object to
identify/encapsulate this repetition, which I'd be happy to do in a
subsequent commit.

Clients cache the set of advertised references at the start of a
negotiation, and keep replaying the same "want SHA1" list to the
server on each negotiation step. If another client pushes into
a branch and moves it by fast-forward, any request to obtain that
branch's prior SHA-1 is still valid, the commit is reachable from
the new position of the reference. Unfortunately the fast-forward
causes smart HTTP negotations to fail, as the server no longer is
advertising that prior SHA-1.
Instead of causing clients to fail out with a "want invalid" error
and forcing the end-user retry, possibly getting into a never ending
try-fail-retry race while other clients are pushing into the same
busy repository, allow the slightly stale want request so long as
it is still reachable.
C Git implemented this same change recently to fix races on the
smart HTTP protocol when the C Git git-http-backend is used.
The new RequestPolicy feature also allows server authors to make
an even more lenient configuration that exports any SHA-1 to the
client. This might be useful in certain settings where a server
has authenticated the client as the "repository owner" and wants
to allow them to grab any content from the server as a complete
unbroken history chain.
The new setAdvertisedRefs() method allows server authors to manually
fix the references that are advertised, possibly bypassing the
getAllRefs() call on the Repository object.

The client's use of UnionInputStream was broken when combined with a
8192 byte buffer used by PackParser. A smart HTTP client connection
always pushes in the execute stateless RPC input stream after the
data stream has ended from the remote peer. At the end of the pack,
PackParser asked to fill a 8192 byte buffer, but if only e.g. 1000
bytes remained UnionInputStream went to the next stream and asked
it for input, which triggered a new RPC, and failed because there
was nothing pending in the request buffer.
Change UnionInputStream to only return what it consumed from a
single InputStream without invoking the next InputStream, just in
case that second InputStream happens to be one of these magical
ones that generates an RPC invocation.

JGit currently identifies loose objects as 'corrupt' if they've been
deflated using a window size less than 32Kb, because the
isStandardFormat() function doesn't recognise the header
byte as a zlib header. This patch makes the method tolerant of
all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice
it's accuracy in distingushing the standard loose-object format
from the experimental (now abandoned) format. It's based on a patch
which has been merged into C-Git master branch:
https://github.com/git/git/commit/7f684a2aff636f44a506
On memory constrained systems zlib may use a much smaller window
size - working on Agit, I found that Android uses a 4KB window;
giving a header byte of 0x48, not 0x78. Consequently all loose
objects generated by the Android platform appear 'corrupt' :(
It might appear that this patch changes isStandardFormat() to the
point where it could incorrectly identify the experimental format as
the standard one, but the two criteria (bitmask & checksum) can only
give a false result for an experimental object where both of the
following are true:
1) object size is exactly 8 bytes when uncompressed (bitmask)
2) [single-byte in-pack git type&size header] * 256
+ [1st byte of the following zlib header] % 31 = 0 (checksum)
As it happens, for all possible combinations of valid object type
(1-4) and window bits (0-7), the only time when the checksum will be
divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which,
due the fields all Commit objects must contain, could never be as
small as 8 bytes in size.
Given this, the combination of the two criteria (bitmask & checksum)
always correctly determines the buffer format, and is more tolerant
than the previous version.

This reverts commit 67b064fc9f.
The "tiny optimization" introduced by 67b0 turns out to have a big
savings on wall-clock time when the object store is very slow (e.g.
the DHT support in JGit), but comes with a much bigger penalty in
space used by the output stream. CGit packed with 67b0 enabled is
7 MiB larger than it should be (36 MiB rather than 28/29 MiB). The
much bigger Linux kernel repository gained over 200 MiB, though some
of this may have been caused by a smaller window setting.
Revert this patch as PackWriter should be optimizing for space used
rather than time spent, since its primary use is network transfer, and
that isn't free.

This change boosts the "Counting objects" phase when JGit is acting
as a server and is packing the linux-2.6 repository for its client.
Compared to CGit on the same hardware, a JGit daemon server is now
21883 objects/sec faster:
CGit:
Counted 2058062 objects in 38981 ms at 52796.54 objects/sec
Counted 2058062 objects in 38920 ms at 52879.29 objects/sec
Counted 2058062 objects in 39059 ms at 52691.11 objects/sec
JGit (before):
Counted 2058062 objects in 31529 ms at 65275.21 objects/sec
Counted 2058062 objects in 30359 ms at 67790.84 objects/sec
Counted 2058062 objects in 30033 ms at 68526.69 objects/sec
JGit (this commit):
Counted 2058062 objects in 28726 ms at 71644.57 objects/sec
Counted 2058062 objects in 27652 ms at 74427.24 objects/sec
Counted 2058062 objects in 27528 ms at 74762.50 objects/sec
Above the first run was a "cold server". For JGit the JVM had just
started up with `jgit daemon`, and for CGit we hadn't touched the
repository "recently" (but it was certainly in kernel buffer cache).
The second and third runs were against the running JGit JVM, allowing
timing tests to better reflect the benefits of JGit's pack and index
caching, as well as any optimizations the JIT may have performed.
The timings are fair. CGit is opening, checking and mmap'ing both
the pack and index during the timer. JGit is opening, checking
and malloc+read'ing the pack and index data into its Java heap
during the timer. Both processes are walking the same graph space,
and are computing the "path hash" necessary to sort objects in the
object table for delta compression. Since this commit only impacts
the "Counting objects" phase, delta compression was obviously not
included in the timings and JGit may still be performing delta
compression slower than CGit, resulting in an overall slower server
experience for clients.

This is useful when the result needs to be displayed and it's only of
interest if the operation was successful or not (in egit, it could be
used in MultiPullResultDialog).

The offset32 format is used for objects <= 2^31-1, while the offset64
format is used for all other objects. This condition was missing
the = needed to ensure an object placed exactly at 2^31 would have
its 64 bit offset in the index.

A non-thin pack does not need to worry about preferred bases, the pack
will be self-contained and all required delta base objects will appear
within the pack itself. Obtaining the path buffer and length from the
ObjectWalk to build the preferred base table is "expensive", so avoid
the cost unless a thin pack is being constructed.

* changes:
PackWriter: Skip progress messages on fast operations
IndexPack: Defer the "Resolving deltas" progress meter
IndexPack: Fix "Resolving deltas" progress meter
The previous comment stated that the value set was used
to keep track of the branch in the remote repository
which was incorrect.
Updated the method comment to match the format used
for the PushCommand.setRemote and FetchCommand.setRemote
methods.

If the "Finding sources" phase will complete in <1 second with no
delta compression enabled, don't bother showing the progress meter for
this phase. Small repositories on the local filesystem tend to rip
through this phase always subsecond and the ProgressMonitor display
can actually slow the operation down.
If delta compression is enabled, there are two phases that may run
very quickly. Set the timer to 500 milliseconds instead, reducing the
risk that the user has to wait longer than 1 second before any sort of
output from the packer occurs.

If delta resolution completes in < 1000 milliseconds, don't bother
showing the progress meter. This is actually very common for a Gerrit
Code Review server, where the client is probably sending 1 commit and
only a few trees/blobs modified... and the base objects are hot in the
process buffer cache.
The 1000 millisecond delay is just a guess at a reasonable time to wait.

This progress meter never reached 100% as it did not update while
resolving the external bases in thin packs.
Instead of updating in batches at the top level, update once per delta
that is resolved. The batching progress meter type should smooth out
the frequent updates to an update rate that is more reasonable to send
to the UI, while also ensuring a successful pack parse always reaches
100% deltas resolved.

Repository inspection tools may find building a reverse index on a
pack useful, as they can then locate an object by offset. As both
C Git and JGit sometimes produce error messages with the offset
rather than the SHA-1, it may be useful to expose this type.

There isn't a good reason to hide all of these as package-private.
Make them public so applications can inspect pack files.

Some embeddings of UploadPack (e.g. Gerrit Code Review) set their own
PackConfig from a server-wide configuration, overriding any JGit
defaults or settings that may exist at the local repository level.
Make a copy constructor form of PackConfig so this server-wide
configuration object can be copied and then merged with repository
specific configuration data.
