Add streams that can encode or decode git binary patch data on the fly.
Git writes binary patches base-85 encoded, at most 52 un-encoded bytes,
with the unencoded data length prefixed in a one-character encoding, and
suffixed with a newline character.
Add a test for both the new input and the output stream. The test
roundtrips binary data of different lengths in different ways.

Add an implementation for base-85 encoding and decoding [1]. Git binary
patches use this format.
Base-85 encoding assembles bytes as 32-bit MSB values, then converts
these values to base-85 numbers (always 5 bytes) encoded as printable
ASCII characters. Decoding base-85 is the reverse operation. Note
that decoding may overflow on invalid input as 85^5 > 2^32. Encodings
always have a length that is a multiple of 5. If input length is not
divisible by 4, padding bytes are (logically) added, which are ignored
when decoding. The encoding for n bytes has thus always exactly length
(n + 3) / 4 * 5 in integer arithmetic (truncating division).
Includes tests.

Git config http.cookieFile must have ~ expansion, compare [1].
It also should be an absolute path. While a relative path is allowed,
C git just passes the value on to libcurl, so it'll be relative to the
current working directory and thus not work in all directories.
Log a warning if the path is relative.
(Alternatives would be to throw an exception, or to resolve the path
relative to the .git directory, or relative to the working tree root,
or relative to the config file it occurs in. But C git does not seem
to do either.)

Add a GpgSignatureVerifier interface, plus a factory to create
instances thereof that is provided via the ServiceLoader mechanism.
Implement the new interface for BouncyCastle. A verifier maintains
an internal LRU cache of previously found public keys to speed up
verifying multiple objects (tag or commits). Mergetags are not handled.
Provide a new VerifySignatureCommand in org.eclipse.jgit.api together
with a factory method Git.verifySignature(). The command can verify
signatures on tags or commits, and can be limited to accept only tags
or commits. Provide a new public WrongObjectTypeException thrown when
the command is limited to either tags or commits and a name resolves
to some other object kind.
In jgit.pgm, implement "git tag -v", "git log --show-signature", and
"git show --show-signature". The output is similar to command-line
gpg invoked via git, but not identical. In particular, lines are not
prefixed by "gpg:" but by "bc:".
Trust levels for public keys are read from the keys' trust packets,
not from GPG's internal trust database. A trust packet may or may
not be set. Command-line GPG produces more warning lines depending
on the trust level, warning about keys with a trust level below
"full".
There are no unit tests because JGit still doesn't have any setup to
do signing unit tests; this would require at least a faked .gpg
directory with pre-created key rings and keys, and a way to make the
BouncyCastle classes use that directory instead of the default. See
bug 547538 and also bug 544847.
Tested manually with a small test repository containing signed and
unsigned commits and tags, with signatures made with different keys
and made by command-line git using GPG 2.2.25 and by JGit using
BouncyCastle 1.65.

If the caller knows already HTTP Basic authentication will be needed
and if it also already has the username and password, preemptive
authentication is a little bit more efficient since it avoids the
initial 401 response.
Add a setPreemptiveBasicAuthentication(username, password) method
to TransportHttp. Client code could call this for instance in a
TransportConfigCallback. The method throws an IllegalStateException
if it is called after an HTTP request has already been made.
Additionally, a URI can include userinfo. Although it is not
recommended to put passwords in URIs, JGit's URIish and also the
Java URL and URI classes still allow it. The underlying HTTP
connection may omit these fields though. If present, take these
fields as additional source for preemptive Basic authentication if
setPreemptiveBasicAuthentication() has not been called.
No preemptive authentication will be done if the connection is
redirected to a different host.
Add tests.

TransportHttp makes several HTTP requests. The SSLContext and socket
factory must be shared over these requests, otherwise authentication
information may not be propagated correctly from one request to the
next. This is important for authentication mechanisms that rely on
client-side state, like NEGOTIATE (either NTLM, if the underlying HTTP
library supports it, or Kerberos). In particular, SPNEGO cannot
authenticate on a POST request; the authentication must come from the
initial GET request, which implies that the POST request must use the
same SSLContext and socket factory that was used for the GET.
Change the way HTTPS connections are configured. Introduce the concept
of a GitSession, which is a client-side HTTP session over several HTTPS
requests. TransportHttp creates such a session and uses it to configure
all HTTP requests during that session (fetch or push). This gives a way
to abstract away the differences between JDK and Apache HTTP connections
and to configure SSL setup outside.
A GitSession can maintain state and thus give all HTTP requests in a
session the same socket factory.
Introduce an extension interface HttpConnectionFactory2 that adds a
method to obtain a new GitSession. Implement this for both existing
HTTP connection factories. Change TransportHttp to use the new
GitSession to configure HTTP connections.
The old methods for disabling SSL verification still exist to support
possibly external connection and connection factory implementations
that do not make use of the new GitSession yet.

Previously, TransportHttp always used the globally set connection
factory. This is problematic if that global factory is changed in
the middle of a fetch or push operation. Initialize the factory to
use in the constructor, then use that factory for all HTTP requests
made through this transport. Provide a setter and a getter for it
so that client code can customize the factory, if needed, in a
TransportConfigCallback.
Once a factory has been used on a TransportHttp instance it cannot
be changed anymore.

Make all transports request protocol V2 when fetching. Depending on
the transport, set the GIT_PROTOCOL environment variable (file and
ssh), pass the Git-Protocol header (http), or set the hidden
"\0version=2\0" (git anon). We'll fall back to V0 if the server
doesn't reply with a version 2 answer.
A user can control which protocol the client requests via the git
config protocol.version; if not set, JGit requests protocol V2 for
fetching. Pushing always uses protocol V0 still.
In the API, there is only a new Transport.openFetch() version that
takes a collection of RefSpecs plus additional patterns to construct
the Ref prefixes for the "ls-refs" command in protocol V2. If none
are given, the server will still advertise all refs, even in protocol
V2.
BasePackConnection.readAdvertisedRefs() handles falling back to
protocol V0. It newly returns true if V0 was used and the advertised
refs were read, and false if V2 is used and an explicit "ls-refs" is
needed. (This can't be done transparently inside readAdvertisedRefs()
because a "stateless RPC" transport like TransportHttp may need to
open a new connection for writing.)
BasePackFetchConnection implements the changes needed for the protocol
V2 "fetch" command (stateless protocol, simplified ACK handling,
delimiters, section headers).
In TransportHttp, change readSmartHeaders() to also recognize the
"version 2" packet line as a valid smart server indication.
Adapt tests, and run all the HTTP tests not only with both HTTP
connection factories (JDK and Apache HttpClient) but also with both

Add the two config constants from C git that can switch on signing
of annotated tags. Add them to the GpgConfig, and implement actually
signing a tag in TagCommand.
The interactions between command line options for "git tag" and config
options is a bit murky in C git. There are two config settings for it:
* tag.gpgSign is the main option, if set to true, it kicks in if
neither -s nor -u are given on the command line.
* tag.forceSignAnnotated signs only tags created via "git tag -m",
but only if command-line option "-a" is not present. It applies
even if tag.gpgSign is set explicitly to false.
Giving -s or -u on the command line also forces an annotated tag
since lightweight tags cannot be signed.

This reverts commit f802f06e7f.
I had misunderstood how protocol V2 works. This implementation only
works if the negotiation during fetch is done in one round.
Fixing this is substantial work in BasePackFetchConnection. Basically
I think I'd have to change back negotiate to the V0 version, and have
a doFetch() that does
if protocol V2
doFetchV2()
else
doFetchV0()
with doFetchV0 the old code, and doFetchV2 completely new.
Plus there would need to be a HTTP test case requiring several
negotiation rounds.
This is a couple of days work at least, and I don't know when I will
have the time to revisit this. So although the rest of the code is
fine I prefer to back this out completely and not leave a only half
working implementation in the code for an indeterminate time.

Previous code used a minimum granularity of 1 microsecond and would
iterate 233 times on a system where the resolution is 1 second (for
instance, Java 8 on Mac APFS).
New code uses a binary search between the maximum we care about (2
seconds) and zero, with a minimum granularity of also 1 microsecond.
This takes at most 19 iterations (guaranteed). For a file system with 1
second resolution, it takes 4 iterations (1s, 0.5s, 0.8s, 0.9s). With
an up-front check at 1 microsecond and at 1 millisecond this performs
equally well as the old code on file systems with a fine resolution.
(For instance, Java 11 on Mac APFS.)

yield bogus values (as observed on HP NonStop). If such an error case

Index format version 4 was introduced in C git in 2012. It's about
time that JGit can deal with it.
Version 4 added prefix path compression. Instead of writing the full
path for each index entry to disk, only the difference to the previous
entry's path is written: a variable-encoded int telling how many bytes
to remove from the previous entry's path to get the common prefix,
followed by the new suffix.
Also, cache entries in a version 4 index are not padded anymore.
Internally, version 3 and version 4 index entries are identical; it's
only the stored format that changes.
Implement this path compression, and make sure we write an index file
that we read previously in the same format. (Only changing from version
2 to version 3 if there are extended flags.)
Add support for the "feature.manyFiles" and the "index.version" git
configs, and honor them when writing a new index file.

read a version 4 index generated by C git and write an identical

The topological sort algorithm in TopoSortGenerator for RevWalk may mix
multiple lines of history, producing results that differ from C git's
git-log whose man page states: "Show no parents before all of its
children are shown, and avoid showing commits on multiple lines of
history intermixed." Lines of history are mixed because
TopoSortGenerator merely delays producing a commit until all of its
children have been produced; it does not immediately produce a commit
after its last child has been produced.
Therefore, add a new RevSort option called TOPO_KEEP_BRANCH_TOGETHER
with a new topo sort algorithm in TopoNonIntermixGenerator. In the
Generator, when the last child of a commit has been produced, unpop
that commit so that it will be returned upon the subsequent call to
next(). To avoid producing duplicates, mark commits that have not yet
been produced as TOPO_QUEUED so that when a commit is popped, it is
produced if and only if TOPO_QUEUED is set.
To support nesting with other generators that may produce the same
commit multiple times like DepthGenerator (for example, StartGenerator
does this), do not increment parent inDegree for the same child commit
more than once.
Commit b5e764abd2 modified the existing
TopoSortGenerator to avoid mixing lines of history, but it was reverted
in e40c38ab08 because the new behavior
caused problems for EGit users. This motivated adding a new Generator
for the new behavior.

malformed string format. Since there is only one formatting argument,
it should be referenced with '{0}' rather than '{1}'.

SSLContext.getInstance("TLS") by default behaves differently on IBM
JDK than on Oracle or OpenJDK.[1] On IBM JDK one gets sockets that
have only TLSv1 enabled, which makes HTTPS connections fail since most
servers refuse this old protocol version. On Oracle JDK/OpenJDK, one
gets sockets with all available protocol versions enabled.
Explicitly enable all available TLS protocol versions to make
HTTPS connections work also on IBM JDK.

When a conflicting file was blamed, JGit would not identify lines
coming from the merge parents. The main cause for this was that
Blame and BlameCommand simply added the first DirCacheEntry found
for a file to its queue of candidates (blobs or commits) to consider.
In case of a conflict this typically is the merge base commit, and
comparing a auto-merged contents against that base would yield
incorrect results.
Such cases have to be handled specially. The candidate to be
considered by the blame must use the working tree contents, but
at the same time behave like a merge commit/candidate with HEAD
and the MERGE_HEADs as parents. Canonical git does something very
similar, see [1].
Implement that and add tests.
I first did this for the JGit pgm Blame command. When I then tried
to do the same in BlameCommand, I noticed that the latter also
included some fancy but incomplete CR-LF handling. In order to
be able to use the new BlameGenerator.prepareHead() also in
BlameCommand this CR-LF handling was also moved into BlameGenerator
and corrected in doing so.
(Just considering the git config settings was not good enough,
CR-LF behavior can also be influenced by .gitattributes, and even
by whether the file in the index has CR-LF. To correctly determine
CR-LF handling for check-in one needs to do a TreeWalk with at
least a FileTreeIterator and a DirCacheIterator.)

Reftable is a binary, block-based storage format for the ref-database.
It provides several advantages over the traditional packed + loose
storage format:
* O(1) write performance, even for deletions and transactions.
* atomic updates to the ref database.
* O(log N) lookup and prefix scans
* free from restrictions imposed by the file system: it is
case-sensitive even on case-insensitive file systems, and has
no inherent limitations for directory/file conflicts
* prefix compression reduces space usage for repetitive ref names,
such as gerrit's refs/changes/xx/xxxxx format.
FileReftableDatabase is based on FileReftableStack, which does
compactions inline. This is simple, and has good median performance,
but every so often it will rewrite the entire ref database.
For testing, a FileReftableTest (mirroring RefUpdateTest) is added to
check for Reftable specific behavior. This must be done separately, as
reflogs have different semantics.
Add a reftable flavor of BatchRefUpdateTest.
Add a FileReftableStackTest to exercise compaction.
Add FileRepository#convertToReftable so existing testdata can be
reused.

This avoids polluting hand-crafted user level config with
auto-configured options which might disturb in environments where
the user level config is replicated between different machines.
Add a jgit config as parent of the system level config. Persist
measured timestamp resolutions always in this jgit config and read it
via the user global config. This has the effect that auto-configured
timestamp resolution will be used by default and can be overridden in
either the system level or user level config.
Store the jgit config under the XDG_CONFIG_HOME directory following the
XDG base directory specification [1] in order to ensure that we have
write permissions to persist the file. This has the effect that each OS
user will use its jgit config since they typically use different
XDG_CONFIG_HOME directories.
If the environment variable XDG_CONFIG_HOME is defined the jgit config
file is located at $XDG_CONFIG_HOME/jgit/config otherwise the default is
~/.config/jgit/config.
If you want to avoid redundant measurement for different OS users
manually copy the values measured and auto-configured for one OS user to
the system level git config.

Since commit c3b0dec509fe136c5417422f31898b5a4e2d5e02, Git has
disallowed writing a non-commit to refs/heads/* refs. JGit still
allows that, which can put users in a bad situation. For example,
git push origin v1.0:master
pushes the tag object v1.0 to refs/heads/master, instead of the
intended commit object v1.0^{commit}.
Prevent that by validating that the target of the ref points to a
commit object when pushing to refs/heads/*.
Git performs the same check at a lower level (in the RefDatabase). We
could do the same here, but for now let's start conservatively by
handling it in pushes first.

It's expected that jgit should work without native git installation.
In such case Security Manager can be configured to deny access to the
files outside of git repository. JGit tries to find cygwin
installation. If Security manager restricts access to some folders
in PATH, it should be considered that those folders are absent
for jgit.
Also JGit tries to detect if symbolic links are supported by OS. If
security manager forbids creation of symlinks, it should be assumed
that symlinks aren't supported.

Cache FileStoreAttributeCache entries since looking up FileStore for a
file may be expensive on some platforms.
Implement a simple LRU cache based on ConcurrentHashMap using a simple
long counter to order access to cache entries.

This enables higher file timestamp resolution on filesystems like ext4,
Mac APFS (1ns) or NTFS (100ns) providing high timestamp resolution on
filesystem level.
Note:
- on some OSes Java 8,9 truncate milliseconds, see
https://bugs.openjdk.java.net/browse/JDK-8177809, fixed in Java 10
- UnixFileAttributes truncates timestamp resolution to microseconds when
converting the internal representation to FileTime exposed in the API,
see https://bugs.openjdk.java.net/browse/JDK-8181493
- WindowsFileAttributes also provides only microsecond resolution

To enable persisting filesystem timestamp resolution per FileStore add a
new config section to the user global git configuration:
- Config section is "filesystem"
- Config subsection is concatenation of
- Java vendor (system property "java.vm.vendor")
- runtime version (system property "java.vm.version")
- FileStore's name
- separated by '|'
e.g.
"AdoptOpenJDK|1.8.0_212-b03|/dev/disk1s1"
The prefix is needed since some Java versions do not expose the full
timestamp resolution of the underlying filesystem. This may also
depend on the underlying operating system hence concrete key values
may not be portable.
- Config key for timestamp resolution is "timestampResolution" as a time
value, supported time units are those supported by
DefaultTypedConfigGetter#getTimeUnit
If timestamp resolution is already configured for a given FileStore
the configured value is used instead of measuring the resolution.
When timestamp resolution was measured it is persisted in the user
global git configuration.
Example:
[filesystem "AdoptOpenJDK|1.8.0_212-b03|/dev/disk1s1"]
timestampResolution = 1 seconds
If locking the git config file fails retry saving the resolution up to 5
times in order to workaround races with another thread.
In order to avoid stack overflow use the fallback filesystem timestamp
resolution when loading FileBasedConfig which creates itself a
FileSnapshot to help checking if the config changed.
Note:
- on some OSes Java 8,9 truncate to milliseconds or seconds, see
https://bugs.openjdk.java.net/browse/JDK-8177809, fixed in Java 10
- UnixFileAttributes up to Java 12 truncates timestamp resolution to
microseconds when converting the internal representation to FileTime
exposed in the API, see https://bugs.openjdk.java.net/browse/JDK-8181493
- WindowsFileAttributes also provides only microsecond resolution up to
Java 12
Hence do not attempt to manually configure a higher timestamp resolution
than supported by the Java version being used at runtime.

It was reported that measuring file timestamp resolution may hang
indefinitely on nfs. Hence timeout this measurement at the known worst
filesystem timestamp resolution (FAT) of 2 seconds.

RevWalk does not currently provide a --first-parent equivalent and the
feature has been requested.
Add a field to the RevWalk class to specify whether walks should
traverse first parents only. Modify Generator implementations to support
the feature.

When loading the config, a FileNotFoundException may occur if the file
exists but cannot be read (see [1]). This is the case on Windows with a
virus scanner checking the file. Therefore if the file exists and that
exception is thrown, retry multiple times, similar to how this was
already implemented for IOException.
