David Pursehouse d0d3773763 T0003_BasicTest: Open autocloseable types in try-with-resource
FileRepository and ObjectInserter.Formatter are autocloseable, so
use try-with-resource for these.

Remove suppression of unused variable warning that is no longer
necessary.

Matthias Sohn 536db18cc6 Implement SHA-256 abstraction
The Large File Storage extension specified by GitHub [1] uses SHA-256 to
compute the ID of large files stored by the extension. Hence implement a
SHA-256 abstraction similar to the SHA-1 abstraction used by JGit.

Hugo Arès df904a4227 Fix diff for added and removed submodule
Since If13f7b406, submodule difference are shown as a hunk. The issue
was that added and removed submodule were considered as Edit.REPLACE
instead of Edit.INSERT and Edit.DELETE in the DiffFormatter result.

Christian Halstrick da43d8d798 Add option to allow empty commits to CommitCommand
CommitCommand should allow to specify whether empty commits (commits
having the same tree as the sole predecessor commit) are allowed or not.
Similar to native git's "--allow-empty" flag.

The defaults differ between JGit and native git even after this change.
When not specifying paths then by default JGit allows to create empty
commits while native git does not. It would be API breaking to change
this now.

This experimental code can be enabled in $GIT_DIR/config:

  [core]
    repositoryformatversion = 1

  [extensions]
    refsBackendType = RefTree

When these are set the repository will read references from the
RefTree rooted by the $GIT_DIR/refs/txn/committed reference.

Update debug-rebuild-ref-tree to rebuild refs/txn/committed only from
the bootstrap layer.  This avoids misuse by rebuilding using packed-refs
and $GIT_DIR/refs tree.

Shawn Pearce 48e245fc60 RefTreeDatabase: Ref database using refs/txn/committed
Instead of storing references in the local filesystem rely on the
RefTree rooted at refs/txn/committed.  This avoids needing to store
references in the packed-refs file by keeping all data rooted under
a single refs/txn/committed ref.

Performance to scan all references from a well packed RefTree is very
close to reading the packed-refs file from local disk.

Storing a packed RefTree is smaller due to pack file compression,
about 49.39 bytes/ref (on average) compared to packed-refs using
~65.49 bytes/ref.

Shawn Pearce 73eb32be82 RefTree: Store references in a Git tree
A group of updates can be applied by updating the tree in one step,
writing out a new root tree, and storing its SHA-1. If references
are stored in RefTrees, comparing two repositories is a matter of
checking if two SHA-1s are identical. Without RefTrees comparing two
repositories requires listing all references and comparing the sets.

Track the "refs/" directory as a root tree by storing references
that point directly at an object as a GITLINK entry in the tree.
For example "refs/heads/master" is written as "heads/master".

Annotated tags also store their peeled value with ^{} suffix, using
"tags/v1.0" and "tags/v1.0^{}" GITLINK entries.

Symbolic references are written as SYMLINK entries with the blob of
the symlink carrying the name of the symbolic reference target.

HEAD is outside of "refs/" namespace so it is stored as a special
"..HEAD" entry. This name is chosen because ".." is not valid in
a reference name and it almost looks like "../HEAD" which names
HEAD if the reader was inside of the "refs/" directory.

A new Command type is required to handle symbolic references and
peeled references.

the objects are OK enough to permit continued use of.

This avoids needing to rewrite history to scrub the broken objects out.

Shawn Pearce 683c41af92 DirCache: Do not create duplicate tree entries
If a file (e.g.  "A") and a subtree file (e.g. "A/foo.c") both appear
in the DirCache this cache should not be written out as a tree object.
The "A" file and "A" subtree conflict with each other in the same tree
and will fail fsck.

Detect this condition during DirCacheBuilder and DirCacheEditor
finish() so the application can be halted early before it updates a
DirCache that might later write an invalid tree structure.

NameConflictTreeWalk needs a bug fix to pop conflicting entries

allow DirCacheBuilderIterator to copy conflicting entries into
the output cache.

Jonathan Nieder 75a0dcac18 Do not let PathFilter.create("a/b") match 'a' unless 'a' is a subtree
PathFilter and PathFilterGroup form JGit's implementation of git's
path-limiting feature in commands like log and diff.  To save time
when traversing trees, a path specification

	foo/bar/baz

tells the tree walker not to traverse unrelated trees like qux/.  It
does that by returning false from include when the tree walker is
visiting qux and true when it is visiting foo.

Unfortunately that test was implemented to be slightly over-eager: it
doesn't only return true when asked whether to visit a subtree "foo"
but when asked about a plain file "foo" as well.  As a result, diffs
and logs restricted to some-file/non-existing-suffix unexpectedly
match against some-file:

     Clean up LICENSE file
[...]

Fix it by checking against the entry's mode.

Gitiles +log has the same bug and benefits from the same fix.

Callers know not to worry about what subtrees are included in the tree
walk because shouldBeRecursive() returns true in this case, so this
behavior change should be safe.  This also better matches the behavior
of C git:

 $ empty=$(git mktree </dev/null)
 $ git diff-tree --abbrev $empty HEAD -- LICENSE/no-such-file
 $ git diff-tree --abbrev $empty HEAD -- tools/no-such-file

and another to check that it does not throw StopWalkException to end
the walk early.

Shawn Pearce 4f8c993c49 push: Do not blindly overwrite peer
If an application uses PushConnection directly on the native Git wire
protocols JGit should send along the application's expected oldId, not
the advertised value.  This allows the remote peer to compare-and-swap
since it was not tested inside JGit.

Discovered when I tried to use a PushConnection (bypassing the
standard PushProcess) and the client blindly overwrote the remote
reference, even though my app had supplied the wrong ObjectId for
the expectedOldObjectId. This was not expected and cost me over an
hour of debugging, plus "corruption" in the remote repository.

By passing along the exact expectedOldObjectId from the app the
remote side can do the check that the application skipped, and
avoid data loss.

This should mirror the behavior of `git push --atomic` where the
client asks the server to apply all-or-nothing. Some JGit servers
already support this based on a custom DFS backend. InMemoryRepository
is extended to support atomic push for unit testing purposes.

Local disk server side support inside of JGit is a more complex animal
due to the excessive amount of file locking required to protect every
reference as a loose reference.

Shawn Pearce b0eb744604 Delay locating .gitattributes until requested
Instead of checking every entry for .gitattributes only look for the
entry on request by TreeWalk.  This avoids impacting uses like RevWalk
filtering history.

When the attrs is requested skip to the start of the tree and look for
.gitattributes until either it is found, or it is impossible to be
present.  Due to the sorting rules of tree entries .gitattributes
should be among the first or second entries in the tree so very few
entries will need to be considered.

Waiting to find the .gitattributes file by native ordering may miss
attrs for files like .config, which sorts before .gitattributes.
Starting from the front of the tree on demand ensures the attributes
are parsed as early as necessary to process any entry in the tree.

Due to TreeWalk recursively processing up the tree of iterators we
cannot just reset the current CanonicalTreeParser to the start as
parent parsers share the same path buffer as their children.
Resetting a parent to look for .gitattributes may overwrite path
buffer data used by a child iterator.  Work around this by building a
new temporary CanonicalTreeParser instance.

Shawn Pearce 761814fe9c DirCacheEntry: Speed up creation by avoiding string cast
The checkPath function is available as a byte[] form, in fact the
String form just converts to byte[] to run the algorithm.

Having DirCacheEntry take a byte[] -> String -> byte[] to check if
each path is valid is a huge waste of CPU time. On some systems it
can double the time required to read 38,999 files from trees to the

Jonathan Nieder 5be4814e38 Repository: Introduce exactRef and findRef, deprecate getRef
The Repository class provides only one method to look up a ref by
name, getRef.  If I request refs/heads/master and that ref does not
exist, getRef will look further in the search path:

 ref/refs/heads/master
 refs/heads/refs/heads/master
 refs/remotes/refs/heads/master

This behavior is counterintuitive, needlessly inexpensive, and usually
not what the caller expects.

Allow callers to specify whether to use the search path by providing
two separate methods:

- exactRef, which looks up a ref when its exact name is known
- findRef, which looks for a ref along the search path

For backward compatibility, keep getRef as a deprecated synonym for
findRef.

This change introduces findRef and exactRef but does not update
callers outside tests to use them yet.

Christian Halstrick 18af2d4265 Let FS_Win32_Cygwin detect symlink support by creating temporary symlink
The class FS_Win32 was always trying out to create a temporary symlink
in order to find out whether symlinks are supported. FS_Win32_Cygwin was
overwriting this method and always returned true. But when the user
running JGit does not have administrative rights then the creation of
symlinks is forbidden even if he is running on FS_Win32_Cygwin. A lot of
tests failed only on the Windows platform because of this. It was
correctly detected that FS_Win32_Cygwin is the filesystem abstraction to
be used but creation of symlinks always failed because of lacking
privileges of the user running the tests.

This fix teaches FS_Win32_Cygwin to behave like FS_Win32 and to test
whether symlinks can be created in order to find out whether symlinks
are supported.

Jonathan Nieder 1e47c7058d RefDirectory.getRef: Treat fake missing symrefs like real ones
getRef() loops over its search path to find a ref:

	Ref ref = null;
	for (String prefix : SEARCH_PATH) {
		ref = readRef(prefix + needle, packed);
		if (ref != null) {
			ref = resolve(ref, 0, null, null, packed);
			break;
		}
	}
	fireRefsChanged();
	return ref;

If readRef returns null (indicating that the ref does not exist), the
loop continues so we can find the ref later in the search path.  And
resolve should never return null, so if we return null it should mean
we exhausted the entire search path and didn't find the ref.

... except that resolve can return null: it does so when it has
followed too many symrefs and concluded that there is a symref loop:

	if (MAX_SYMBOLIC_REF_DEPTH <= depth)
		return null; // claim it doesn't exist

Continue the loop instead of returning null immediately.  This makes
the behavior more consistent.

Arguably getRef should throw an exception when a symref loop is
detected.  That would be a more invasive change, so if it's a good
idea it will have to wait for another patch.

Jonathan Nieder 797f94d331 RefDirectory.exactRef: Do not ignore symrefs to unborn branch
When asked to read a symref pointing to a branch-yet-to-be-born (such
as HEAD in a newly initialized repository), DfsRepository and
FileRepository return different results.

FileRepository:

	exactRef("HEAD") => null

DfsRepository:

	exactRef("HEAD") => SymbolicRef[HEAD -> refs/heads/master=00000000]

getRef("HEAD") returns the same as DfsRepository's exactRef in both
backends.

The intended behavior is the DfsRepository one: exactRef() is supposed
to be like getRef(), but more exact because it doesn't need to
traverse the search path.

The discrepancy is because DfsRefDatabase implements exactRef()
directly with the intended semantics, while RefDirectory uses a
fallback implementation built on top of getRefs().  getRefs() skips
symrefs to an unborn branch.

Override the fallback implementation with a correct implementation
that is similar to getRef() to avoid this.  A followup change will fix
the fallback.

Mike Williams c4d73fb7cc Insert duplicate objects to prevent race during garbage collection.
Prior to this change, DfsInserter would not insert an object into a pack
if it already existed in another pack in the repository, even if that
pack was unreachable. Consider this sequence of events:

- Object FOO is pushed to a repository.
- Subsequent ref changes make FOO UNREACHABLE_GARBAGE.
- FOO is subsequently re-inserted using a DfsInserter, but skipped
  due to existing in UNREACHABLE_GARBAGE.
- The repository is repacked; FOO will not be written into a new pack
  because it is not yet reachable from a reference. If the
  UNREACHABLE_GARBAGE packs are deleted, FOO disappears.
- A reference is updated to reference FOO. This reference is now broken
  as FOO was removed when the repacking process deleted the
  UNREACHABLE_GARBAGE pack that stored the only copy of FOO.

The garbage collector can't safely delete the UNREACHABLE_GARBAGE
pack because FOO might be in the middle of being re-inserted/re-packed.

This change writes a duplicate copy of an object if it only exists in
UNREACHABLE_GARBAGE. This "freshens" the object to give it a chance to
survive long enough to be made reachable through a reference.

When commits are selected for bitmap generation, they are reordered
so that related "chains" of commits are grouped together. Chains are
"subbranches" of commits that may branch off of and re-merge with the
main line. Grouping by chains means that the XOR difference between
consecutive selected commits will be smaller, resulting in better
run-length compression of the XORed bitmaps.

Add a new testSelectionOrderingWithChains() test in a new
GcCommitSelectionTest test class. Also move related GC commit selection
tests out of GcBasicPackingTest and into GcCommitSelectionTest.

The value of bitmapContiguousCommitCount, whereby bitmaps are
created for the most recent N commits in a branch, has never
been verified. If experiments show that they are not valuable,
then we can simplify the implementation so that there is only
a concept of recent and distant commit history (defined by
"bitmapRecentCommitCount"), and the only controls we need are
"bitmapRecentCommitSpan" and "bitmapDistantCommitSpan".

Terry Parker 320a4142ad Update bitmap selection throttling to fully span active branches.
Replace the “bitmapCommitRange” parameter that was recently introduced
with two new parameters: “bitmapExcessiveBranchCount” and
“bitmapInactiveBranchAgeInDays”. If the count of branches does not
exceed “bitmapExcessiveBranchCount”, then the current algorithm is kept
for all branches.

If the branch count is excessive, then the commit time for the tip
commit for each branch is used to determine if a branch is “inactive”.
"Active" branches get full commit selection using the existing
algorithm. "Inactive" branches get fewer bitmaps near the branch tips.

Introduce a "contiguousCommitCount" parameter that always enforces that
the N most recent commits in a branch are selected for bitmaps. The
previous nextSelectionDistance() algorithm created anywhere from 1-100
contiguous bitmaps at branch tips.

For example, consider a branch with commits numbering 0-300, with 0
being the most recent commit. If the most recent 200 commits are not
merge commits and the 200th commit was the last one selected,
nextSelectionDistance() returned 100, causing commits 200-101 to be
ignored. Then a window of size 100 was evaluated, searching for merge
commits. Since no merge commits are found, the next commit (commit 0)
was selected, for a total of 1 commit in the topmost 100 commits.

If instead the 250th commit was selected, then by the same logic
commit 50 is selected. At that point nextSelectionDistance() switches to
selecting consecutive commits, so commits 0-50 in the topmost 100
commits are selected. The "contiguousCommitCount" parameter provides
more determinism by always selecting a constant number or topmost
commits.

Add an optimization to break out of the inner loop of selectCommits() if
all of the commits for the current branch have already been found.

When reusing bitmaps from an existing pack, remove unnecessary
populating and clearing of the writeBitmaps/PackBitmapIndexBuilder.

Add comments to PackWriterBitmapPreparer, rename methods and variables
for readability.

Add tests for bitmap selection with and without merge commits and with
excessive branch pruning triggered.

Note: I will follow up with an additional change that exposes the new
parameters through PackConfig.

Terry Parker 2524157d3d Limit the range of commits for which bitmaps are created.
A bitmap index contains bitmaps for a set of commits in a pack file.
Creating a bitmap for every commit is too expensive, so heuristics
select the most "important" commits. The most recent commits are the
most valuable. To clone a repository only those for the branch tips are
needed. When fetching, only commits since the last fetch are needed.

The commit selection heuristics generally work, but for some
repositories the number of selected commits is prohibitively high. One
example is the MSM 3.10 Linux kernel. With over 1 million commits on
2820 branches, the current heuristics resulted in +36k selected commits.
Each uncompressed bitmap for that repository is ~413k, making it
difficult to complete a GC operation in available memory.

The benefit of creating bitmaps over the entire history of a repository
like the MSM 3.10 Linux kernel isn't clear. For that repository, most
history for the last year appears to be in the last 100k commits.
Limiting bitmap commit selection to just those commits reduces the count
of selected commits from ~36k to ~10.5k. Dropping bitmaps for older
commits does not affect object counting times for clones or for fetches
on clients that are reasonably up-to-date.

This patch defines a new "bitmapCommitRange" PackConfig parameter to
limit the commit selection process when building bitmaps. The range
starts with the most recent commit and walks backwards. A range of 10k
considers only the 10000 most recent commits. A range of zero creates
bitmaps only for branch tips. A range of -1 (the default) does not limit

Stefan Beller cdd7c23446 RepoCommand: Add setRecordRemoteBranch option to record upstream branch
On a server also running Gerrit that is using RepoCommand to
convert from an XML manifest to a git submodule superproject
periodically, it would be handy to be able to use Gerrit's
submodule subscription feature[1] to update the superproject
automatically between RepoCommand runs as changes are merged
in each subprojects.

This requires setting the 'branch' field for each submodule
so that Gerrit knows what branch to watch.  Add an option to
do that.

Setting the branch field also is useful for plain Git users,
since it allows them to use "git submodule update --remote" to
manually update all submodules between RepoCommand runs.

Andrey Loskutov 1a2b4e246d [ignore rules] fix for handling unmatched '[' brackets
This patch makes JGit parsing of ignore rules containing unmatched '['
bracket compatible to the Git CLI.

Since '[' starts character group, Git tries to parse the ignore rule as
a shell glob pattern and if the character group is not closed, the glob
pattern is invalid and so the ignore rule never matches anything.

Andrey Loskutov 1abd51d953 [ignore rules] fix for backslash handling
An attempt to re-implement not well documented Git CLI behavior for
patterns with backslashes.

It looks like Git silently ignores all \ characters in ignore rules, if
they are NOT covered by 3 cases described in [1]:

{quote}
1) ... Put a backslash ("\") in front of the first hash for patterns
that begin with a hash.
...
2) Trailing spaces are ignored unless they are quoted with backslash
("\").
...
3) Put a backslash ("\") in front of the first "!" for patterns that
begin with a literal "!", for example, "\!important!.txt".
{quote}

Undocumented also is the fact that backslash itself can be escaped by
backslash.

So \h\e\l\l\o\.t\x\t rule matches hello.txt and a\\\\b a\b in Git CLI.

Additionally, the glob parser [2] knows special meaning of backslash:

{quote}
One can remove the special meaning of '?', '*' and '[' by preceding
them by a backslash, or, in case this is part of a shell command
line, enclosing them in quotes.  Between brackets these characters
stand for themselves.  Thus, "[[?*\]" matches the four characters
'[', '?', '*' and '\'.
{quote}

Jacob Keller a28ba3f2c7 Show submodule difference as a hunk
Current DiffFormat behavior regarding submodules (aka git links) is

header, rather than as its own hunk.

 +Subproject commit ec6ed89c47ba7223f82d9cb512926a6c5081343e

The current way of processing submodules results in no hunk header and
includes the contents of the hunk as part of the headers. To fix this, we
can't just have our writeGitLinkDiffText output the hunk header. We have
to change the flow so that the raw text gets parsed as a diff. The easiest
way to do this is to fake the RawText in the FormatResult when we have a
GITLINK.

It should be noted that it seems possible for there to be a difference
between a GITLINK and a non-GITLINK, but I don't think this can happen in
practice, so I don't think we need to worry too much about it.

This patch also fixes up the test for GitLink headers, as the test was
for the old behavior. My setup has 3 other failing tests which may or
may not be the result of environmental changes. However, the same tests
fail without this commit, so I do not believe they are related.

want to store the cert in "refs/for/master@{cert}", since that may
lead someone looking to the ref to the incorrect conclusion that that
ref exists.

Add a separate put method that takes a collection of commands, and
only stores certs on those refs that have a matching command in the
cert.

Dave Borowitz d5a71e9ca3 Store push certificates in refs/meta/push-certs
Inspired by a proposal from gitolite[1], where we store a file in
a tree for each ref name, and the contents of the file is the latest
push cert to affect that ref.

The main modification from that proposal (other than lacking the
out-of-git batching) is to append "@{cert}" to filenames, which allows
storing certificates for both refs/foo and refs/foo/bar. Those
refnames cannot coexist at the same time in a repository, but we do
not want to discard the push certificate responsible for deleting the
ref, which we would have to do if refs/foo in the push cert tree
changed from a tree to a blob.

The "@{cert}" syntax is at least somewhat consistent with
gitrevisions(7) wherein @{...} describe operators on ref names.

As we cannot (currently) atomically update the push cert ref with the
refs that were updated, this operation is inherently racy. Kick the can
down the road by pushing this burden on callers.

is for trailing LFs in pkt-lines to be optional. Go back to using
PacketLineIn#readString() everywhere.

For push certificates specifically, we agreed that the payload signed
by the client is always concatenated with LFs even though the client
MAY omit LFs when framing the certificate for the wire. This is still
reflected in the implementation of PushCertificate#toText().

Dave Borowitz e49e7b4bd4 Add a separate type for the identity in a push certificate
These differ subtly from a PersonIdent, because they can contain
anything that is a valid User ID passed to gpg --local-user. Upstream
git push --signed will just take the configuration value from
user.signingkey and pass that verbatim in both --local-user and the
pusher field of the certificate. This does not necessarily contain an
email address, which means the parsing implementation ends up being
substantially different from RawParseUtils.parsePersonIdent.
Nonetheless, we try hard to match PersonIdent behavior in
questionable cases.

Dave Borowitz b822f9b51d PushCertificateParser: include begin/end lines in signature
The signature is intended to be passed to a verification library such
as Bouncy Castle, which expects these lines to be present in order to
parse the signature.

Dave Borowitz 8d0cedf2ec Extract a class for signed push configuration
The default behavior is to read a repository's signed push
configuration from that repo's config file, but this is not very
flexible when it comes to managing groups of repositories (e.g. with
Gerrit). Allow callers to override the configuration using a POJO.

Jonathan Nieder d2ade728a1 Treat CloneCommand.setRemote(null) as setRemote("origin")
A non-bare clone command with null remote produces a
NullPointerException when trying to produce a refspec to fetch against.

In a bare repository, a null remote name is accepted by mistake,
producing a configuration with items like 'remote.url' instead of
'remote.<remote>.url'.  This was never meant to work.

Instead, let's make setRemote(null) undo any previous setRemote calls
and re-set the remote name to DEFAULT_REMOTE, imitating C git clone's
--no-origin option.

While we're here, add some tests for setRemote working normally.

  Rewrite push certificate parsing
  Allow trailing newlines in receive-pack

Dave Borowitz a85e817dc2 Rewrite push certificate parsing
- Consistently return structured data, such as actual ReceiveCommands,
  which is more useful for callers that are doing things other than
  verifying the signature, e.g. recording the set of commands.
- Store the certificate version field, as this is required to be part
  of the signed payload.
- Add a toText() method to recreate the actual payload for signature
  verification. This requires keeping track of the un-chomped command
  strings from the original protocol stream.
- Separate the parser from the certificate itself, so the actual
  PushCertificate object can be immutable. Make a fair attempt at deep
  immutability, but this is not possible with the current mutable
  ReceiveCommand structure.
- Use more detailed error messages that don't involve NON-NLS strings.
- Document null return values more thoroughly. Instead of having the
  undocumented behavior of throwing NPE from certain methods if they
  are not first guarded by enabled(), eliminate enabled() and return
  null from those methods.
- Add tests for parsing a push cert from a section of pkt-line stream
  using a real live stream captured with Wireshark (which, it should
  be noted, uncovered several simply incorrect statements in C git's
  Documentation/technical/pack-protocol.txt).

This is a slightly breaking API change to classes that were
technically public and technically released in 4.0. However, it is
highly unlikely that people were actually depending on public
behavior, since there were no public methods to create
PushCertificates with anything other than null field values, or a
PushCertificateParser that did anything other than infinite loop or
throw exceptions when reading.
