Sometimes, it is necessary to cancel a garbage collection operation.
When GC is called using the standalone executable, i.e., from a command
line, Control-Cing the process does the trick. When calling GC
programmatically, though, there is no mechanism to do it.
Add checks in the GC process so that a custom cancellable progress
monitor could be passed in order to cancel the operation at specific
points. In this case, the calling process set the cancel flag in the
progress monitor and the GC process will throw an exception that can
be caught and handled by the caller accordingly.

Using try-with-resource means that close() will automatically be
called on the Repository object. However, according to the javadoc
of Git#close():
If the repository was opened by a static factory method in this class,
then this method calls Repository#close() on the underlying repository
instance.
This means that Repository#close() is called twice, by Git.close()
and in the outer try-with-resource, leading to a corrupt use count.

The Compacter and Garbage Collector will record the estimated size of
the newly going to be created compact, gc or garbage packs. This
information can be used by the clients to better make a call on how to
actually store the pack based on the approximated expected size.
Added a new protected method DfsObjDatabase.newPack(PackSource
packSource, long estimatedPackSize), so that the clients can override
this method to make use of the estimatedPackSize while creating a new
PackDescription object. The default implementation of this method is
equivalent to
newPack(packSource).setEstimatedPackSize(estimatedPackSize). I didn't
make it abstract because that would force all the existing sub classes
of DfsObjDatabase to implement this method. Due to this default
implementation, the estimatedPackSize is added to DfsPackDescription
using a setter instead of a constructor parameter (even though
constructor parameter would be a better choice as this value is set only
during the object creation).

An unreferenced object might appear in a pack. This could only happen
because it was previously referenced, and then later that reference
was removed. When we gc, we copy the referenced objects into a new
pack, and delete the old pack. This would remove the unreferenced
object. Now we first create a loose object from any unreferenced
object in the doomed pack. This kicks off the two-week grace period
for that object, after which it will be collected if it's not
referenced.
This matches the behavior of regular git.

The new --prune-preserved option prunes old pack files from the

These options are designed to prevent stale file handle exceptions

This fixes a nasty performance issue for repositories that have many
objects referenced through refs/tags/, but not in refs/heads/.
Situations like this can arise when a project has made releases like
refs/tags/v1.0, and then decides to orphan history and start over for
version 2. The v1.0 objects are not reachable from master anymore,
but are still live due to the v1.0 tag.
When tags are packed in the GC_OTHER pack, bitmaps are not able to
cover the repository's contents. This may cause very slow counting
times during git clone, as the server must enumerate the ancient
history under refs/tags/ to respond to the client.
Clients by default always ask for all tags when asking for all heads
during clone. This has been true since git-core commit 8434c2f1afedb
(Apr 27 2008), when clone was converted to a builtin. Including tags
in the main GC pack should still allow servers to benefit from the
fast full pack reuse path when serving a clone to a client.

When a repository is being GCed and a concurrent push is received, there
is the possibility of having a missing object. This is due to the fact
that after the list of objects to delete is built, there is a window of
time when an unreferenced and ready to delete object can be referenced
by the incoming push. In that case, the object would be deleted because
there is no way to know it is no longer unreferenced. This will leave
the repository in an inconsistent state and most of the operations fail
with a missing tree/object error.
Given the incoming push change the last modified date for the now
referenced object, verify this one is still a candidate to delete
before actually performing the delete operation.

FileSnapshot.isModified may have reported a file to be clean although it
was actually dirty.
Imagine you have a FileSnapshot on file f. lastmodified and lastread are
both t0. Now time is t1 and you
1) modify the file
2) update the FileSnapshot of the file (lastModified=t1, lastRead=t1)
3) modify the file again
4) wait 3 seconds
5) ask the Filesnapshot whether the file is dirty or not. It erroneously
answered it's clean.
Any file which has been modified longer than 2.5 seconds ago was
reported to be clean. As the test shows that's not always correct.
The real-world problem fixed by this change is the following:
* A gerrit server using JGit to serve git repositories is processing
fetch requests while simultaneously a native git garbage collection
runs on the repo.
* At time t1 native git writes temporary files in the pack folder
setting the mtime of the pack folder to t1.
* A fetch request causes JGit to search for new packfiles and JGit
remembers this scan in a Filesnapshot on the packs folder. Since the gc
is not finished JGit doesn't see any new packfiles.
* The fetch is processed and the gc ends while the filesystem timer is
still t1. GC writes a new packfile and deletes the old packfile.
* 3 seconds later another request arrives. JGit does not yet know about
the new packfile but is also not rescanning the pack folder because it
cached that the last scan happened at time t1 and pack folder's mtime is
also t1. Now JGit will not be able to resolve any object contained in
this new pack. This behavior may be persistent if objects referenced by
the ref/meta/config branch are affected so gerrit can't read permissions
stored in the refs/meta/config branch anymore and will not allow any
pushes anymore. The pack folder will not change its mtime and therefore
no rescan will take place.

Fix JGits merge-base calculation in case of inconsistent commit times.
JGit was potentially failing to compute correct merge-bases when the
commit times where inconsistent (a parent commit was younger than a
child commit). The code in MergeBaseGenerator was aware of the fact that
sometimes the discovery of a merge base x can occur after the parents of
x have been seen (see comment in #carryOntoOne()). But in the light of
inconsistent commit times it was possible that these parents of a
merge-base have already been returned as a merge-base.
This commit fixes the bug by buffering all commits generated by
MergeBaseGenerator. It is expected that this buffer will be small
because the number of merge-bases will be small. Additionally a new
flag is used to mark the ancestors of merge-bases. This allows to filter
out the unwanted commits.

TransportHttp sets 'Accept-Encoding: gzip' to allow the server to
compress HTTP responses. When fetching a loose object over HTTP, it
uses the following code to read the response:
InputStream in = openInputStream(c);
int len = c.getContentLength();
return new FileStream(in, len);
If the content is gzipped, openInputStream decompresses it and produces
the correct content for the object. Unfortunately the Content-Length
header contains the length of the compressed stream instead of the
actual content length. Use a length of -1 instead since we don't know
the actual length.
Loose objects are already compressed, so the gzip encoding typically
produces a longer compressed payload. The value from the Content-Length
is too high, producing EOFException: Short read of block.

Now that RepositoryCache have a time based eviction strategy, get rid
of the strategy to evict cache entries if heap memory is running low,
i.e. soft references. Main reason why time based eviction was
implemented was to offer an alternative to the unpredictable soft
references.
Relying on soft references is not working, especially in large heap. The
JVM GC will consider collecting soft references as last resort before
throwing an out of memory error. For example, an application like Gerrit
configured with a 128GB heap, GC will wait until all 128GB is filled
before collecting the soft references so the application will be
suffering long pauses caused by GC for a long time already. In other
words, you will have to restart application because it's unusable before
JVM eviction kicks in.
Keeping the SoftReference in RepositoryCache is causing more harm than
good. If you use the time based eviction (which is the default strategy)
and want to tune JVM to release soft references more aggressively, it
will release repositories from the cache even though they are not
expired which defeats the purpose of the repository cache.
Gerrit uses Lucene library which uses soft references and this is
causing a "memory leak" except if you configure JVM to release soft
references more aggressively which have the nasty side effect of
evicting non expired repositories from the cache.

Run write and flush on a single threaded Executor using

If any operation was interrupted the state of the stream

StreamCopyThread.flush was introduced in
61645b938bc934fda3b0624c5bac1e3495634750 (Add timeouts to smart
transport clients, 2009-06-19) to support timeouts on write in JSch.
The commit message from that change explains:
JSch made a timeout on write difficult because they explicitly do
a catch for InterruptedException inside of their OutputStream. We
have to work around that by creating an additional thread that just
shuttles data between our own OutputStream and the real JSch stream.
The code that runs on that thread is structured as follows:
while (!done) {
int n = src.read(buf);
dst.write(buf, 0, n);
}
with src being a PipedInputStream representing the data to be written
to JSch. To add flush support, that change wanted to add an extra step
if (wantFlush)
dst.flush();
but to handle the case where the thread is blocked in the read() call
waiting for new input, it needs to interrupt the read. So that is how
it works: the caller runs
pipeOut.write(some data);
pipeOut.flush();
copyThread.flush();
to write some data and force it to flush by interrupting the read.
After the pipeOut.flush(), the StreamCopyThread reads the data that was
written and prepares to copy it out. If the copyThread.flush() call
interrupts the copyThread before it acquires writeLock and starts
writing, we throw away the data we just read to fulfill the flush.
Oops.
Noticed during the review of e67d59df3f
(StreamCopyThread: Do not let flush interrupt a write, 2016-11-04),
which introduced this bug.

ObjectId is serializable, and so are its subtypes. Ensure that
serialization does not follow the hash collision chain internal to the
ObjectIdOwnerMap, otherwise completely unrelated objects may get
serialized when a RevObject is serialized.
Note that serializing a RevCommit or RevTag may serialize quite a few
objects due to the parent/object links they contain. A user has no real
control over how many objects will be written when a RevCommit is
serialized. C.f [1]. This change does not resolve that, but in any case
this internal hash collision chain link should not participate in

With the auto option, gc checks whether any housekeeping is required; if
not, it exits without performing any work. Some JGit commands run gc
--auto after performing operations that could create many loose objects.
Housekeeping is required if there are too many loose objects or too many
packs in the repository.
If the number of loose objects exceeds the value of the gc.auto option
jgit's GC consolidates all existing packs into a single pack (equivalent
to -A option), whereas git-core would combine all loose objects into a
single pack using repack -d -l. Setting the value of gc.auto to 0
disables automatic packing of loose objects.
If the number of packs exceeds the value of gc.autoPackLimit, then
existing packs (except those marked with a .keep file) are consolidated
into a single pack by using the -A option of repack. Setting
gc.autoPackLimit to 0 disables automatic consolidation of packs.
Like git the following jgit commands run auto gc:
- fetch
- merge
- rebase
- receive-pack
The auto gc for receive-pack can be suppressed by setting the config
option receive.autogc = false

Git barfs on these (and they don't make any sense), so we certainly
shouldn't write them.

The 'factory' field is lazy initialized in the detect() method.
According to FindBugs:
Because the compiler or processor may reorder instructions, threads
are not guaranteed to see a completely initialized object, if the
method can be called by multiple threads.
Fix this by declaring the member as 'volatile'.
