- 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.

C git's receive-pack.c strips trailing newlines in command lists when
present[1], although send-pack.c does not send them, at least in the
case of command lists[2]. Change JGit to match this behavior.
Add tests.
This also fixes parsing of commands in the push cert, which, unlike
commands sent in the non-push case, always have trailing newlines.

Revert "Config: Distinguish between empty and null strings"
This reverts commit 96eb3ee3976e7e9e3e118851fa614cce8a1f7d88, which
broke Gerrit tests that set a config value to 'null', serialize the
result, deserialize, and expect 'null' from Config.getString[1].
The intent of that commit was to make it possible to distinguish between
an absent and an empty config value, which we'll have to do with a new
method.
Revert the behavior change. Keep the tests from 428cb23f2de8, since
they test the behavior more precisely than the old tests did.

UploadPack: Use reachable-sha1-in-want configuration
C git 2.5 supports setting the equivalent of
RequestPolicy.REACHABLE_COMMIT with uploadpack.allowreachablesha1inwant.
Parse this into TransportConfig and use it from UploadPack. An explicitly
set RequestPolicy overrides the config, and the policy may still be
upgraded on a unidirectional connection to avoid races.

exactRef(ref1, ref2, ref3) requests multiple specific refs in a single
lookup, which may be faster in some backends than looking them up one by
one.
firstExactRef generalizes getRef by finding the first existing ref from
the list of refs named. Its main purpose is for the default
implementation of getRef (finding the first existing ref in a search
path). Hopefully it can be useful for other operations that look for
refs in a search path (e.g., git log --notes=<name>), too.

Introduce exactRef to read a ref whose exact name is known
Unlike getRef(name), the new exactRef method does not walk the search
path. This should produce a less confusing result than getRef when the
exact ref name is known: it will not try to resolve refs/foo/bar to
refs/heads/refs/foo/bar even when refs/foo/bar does not exist.
It can be faster than both getRefs(ALL).get(name) and getRef(name)
because it only needs to examine a single ref.
A follow-up change will introduce a findRef synonym to getRef and
deprecate getRef to make the choice a caller is making more obvious
(exactRef or findRef, with the same semantics as getRefs(ALL).get and
getRefs(ALL).findRef).

I am developing an offline pack verification feature based on
PackParser. The birthday collision check is a prohibitive obstacle
to performance at scale because it interacts with the repository
to perform collision checks. This CL restores the checkObjectCollisions
flag that was removed in 9638e0aa87614a6fb4f109bbeac0cde3462b9769,
while changing the flag getter and setter to protected from public as a
precaution against misuse.

Config: Allow ending a file with "=" and no newline
This is a perfectly valid construction according to C git:
$ echo -en '[a]\nx =' > foo.config

Config: Distinguish between empty and null strings
The C git API and command line tools distinguish between a key having
the empty string as a value and no key being present in the config
file:
$ echo -e '[a]\nx =' > foo.config
$ git config -f foo.config a.x; echo $?
0
$ git config -f foo.config a.y; echo $?
1
Make JGit make the same distinction. This is in line with the current
Javadoc of getString, which claims to return "a String value from the
config, null if not found". It is more reasonable to interpret "x ="
in the above example as "found" rather than "missing".
We need to maintain the special handling of a key name with no "="
resolving to a boolean true, but "=" with an empty string is still not
a valid boolean.

Use message from ServiceNotAuthorizedException, ServiceNotEnabledException
When sending an error response due to ServiceNotAuthorizedException or
ServiceNotEnabledException, usually we send a default message. In the
ServiceNotEnabledException case, we use
403 Git access forbidden
except in a dumb-HTTP-specific filter where we use the servlet
container's default 403 response:
403 Forbidden
In the ServiceNotAuthorizedException case, we use the servlet
container's default 401 response:
401 Unauthorized
There is one exception: a ServiceNotEnabledException when handling a
smart HTTP /info/refs request uses the message from the exception:
403 Service not enabled
Be more consistent by always using the message from the exception. This
way, authors of a RepositoryResolver, UploadPackFactory, or
ReceivePackFactory can provide a more detailed message when appropriate.
The defaults are
401 Unauthorized
403 Service not enabled

Clarify description of ServiceNotAuthorizedException
This exception's detail message states
Service not permitted
and according to the Javadoc it indicates that the current user does not
have access to the service. In practice, though, callers handle this
exception by presenting a '401 Unauthorized' response to the client,
meaning that the user is unauthenticated and should authenticate.
Clarify the documentation and detail message to match the practice.
The exception message is not used anywhere except logs. No
client-visible effect intended.
