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.

This is the subclass of IOException already thrown by
BaseReceivePack#recvCommands when encountering an invalid value on

same subclass.

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.

Add a missing continues to prevent falling through to the command
parsing section. The first continue happens when the command list is
empty, so change the condition to see whether we have read the first
line, rather than any commands.
Fix comparison to BEGIN_SIGNATURE to use raw line with newline.

a85e817d 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.

UploadPackLogger is incorrectly named--it can be used to trigger any
post upload action, such as GC/compaction. This change introduces
PostUploadHook/PostUploadHookChain to replace
UploadPackLogger/UploadPackLoggerChain and deprecates the latter.
It also introduces PackStatistics as a replacement for
PackWriter.Statistics, since the latter is not public API.
It changes PackWriter to use PackStatistics and reimplements
PackWriter.Statistics to delegate to PackStatistics.

This method is documented to take a branch name (not a possibly null
string). The only way a caller could have set null without either
re-setting to a sane value afterward or producing NullPointerException
was to also call setNoCheckout(true), in which case there would have
been no reason to set the branch in the first place.
Make setBranch(null) request the default behavior (remote's default
branch) instead, imitating C git's clone --no-branch.

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.

These commands' monitor fields can never be null unless someone passes
null to setProgressMonitor. Anyone passing null probably meant to
disable the ProgressMonitor, so do that (by falling back to
NullProgressMonitor.INSTANCE) instead of saving a null and eventually
producing NullPointerException.

- 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

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.

This reverts commit 96eb3ee397, 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.

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.

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).

to performance at scale because it interacts with the repository

while changing the flag getter and setter to protected from public as a
precaution against misuse.

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.

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.
