Dave Borowitz 618f213da0 PushCertificateParser: Add method for parsing from a stream
We intend to store received push certificates somewhere, like a
particular ref in the repository in question. For reading data back
out, it will be useful to read push certificates (without pkt-line
framing) in a streaming fashion.

Dave Borowitz 469734bf87 BaseReceivePack: Treat all LFs as optional
Discussion on the git mailing list has concluded[1] that the intended
behavior for all (non-sideband) portions of the receive-pack protocol
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().

Jonathan Nieder 761f070866 Throw InvalidObjectIdException from ObjectId.fromString("tooshort")
ObjectId.fromString already throws InvalidObjectIdException for most
malformed object ids, but for this kind it previously threw
IllegalArgumentException.  Since InvalidObjectIdException is a child of
IllegalArgumentException, callers that catch IllegalArgumentException
will continue to work.

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.

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
2015-06-11 13:07:44 -04:00
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.

Dave Borowitz d43703624c Allow trailing newlines in receive-pack
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.

Jonathan Nieder a1fd4980df submodule test: Use config.unset instead of setting to null
Most relative-URL tests for SubmoduleInitCommand carry out the following
steps:

 1. add a submodule at path "sub" to the index
 2. set remote.origin.url in .git/config
 3. configure .gitmodules, possibly using relative URLs, and see what
    happens

resolveWorkingDirectoryRelativeUrl() is meant to test the fallback when
remote.origin.url is not set, to match C git which treats the URL as
relative to the cwd in that case.  To do so, in step (2) it sets
remote.origin.url to null.

However, Config.setString when taking a null value does not actually
unset that value from the configuration --- it sets it to the empty
string.  This means we are testing a behavior that C git never
supported.  Use Config.unset instead.

This reverts commit 96eb3ee397, which

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.

Jonathan Nieder 48b67012d6 Allow lookup of multiple exact refs in one shot
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.

Jonathan Nieder a04d1ad2f1 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).

Dave Borowitz 96eb3ee397 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.

One case was repeated hit on the head of the chain. moveToHead(e)

Shawn Pearce bfdd963083 FS_POSIX: Rework umask detection to make it settable
Avoid always calling `sh -c umask` on startup, instead deferring
the invocation until the first time a working tree file needs to
use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.

Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.

Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.
