Thomas Wolf ffd1ac5dde Fix fetching with duplicate ref updates
If packed refs are used, duplicate updates result in an exception
because JGit tries to lock the same lock file twice. With non-atomic
ref updates, this used to work, since the same ref would simply be
locked and updated twice in succession.

Let's be more lenient in this case and remove duplicates before
trying to do the ref updates. Silently skip duplicate updates
for the same ref, if they both would update the ref to the same
object ID. (If they don't, behavior is undefined anyway, and we
still throw an exception.)

Add a test that results in a duplicate ref update for a tag.

Hector Caballero 4eea4ea508 GC: Remove empty references folders
After packaging references, the folders containing these references are
not deleted. In a busy repository, this causes operations to slow down
as traversing the references tree becomes longer.

Delete empty reference folders after the loose references have been
packed.
To avoid deleting a folder that was just created by another concurrent
operation, only delete folders that were not modified in the last 30
seconds.

Marcel Trautwein 5429d1a0cf Make JGit describe behaves same as c-git for lightweight tags
JGit now considers lightweight tags only if the --tags option is set
i.e. `git.describe().setAllTags(true)` has to be set, else the default
is now as in c git:

Only annotated tags are evaluated unless you pass true
equivalent to --tags (or --all) by the option setAllTags.

Hint: This (still) doesn't address any difference between c-git
`--all` and `!--all --tags` behavior;
perhaps this might be a follow up request

David Pursehouse f6c4a492d0 Repository: Deprecate #peel method
Callers should use getRefDatabase().peel(ref) instead since it
doesn't swallow the IOException.

Adapt all trivial callers to user the alternative.

DescribeCommand still uses the deprecated method and is not adapted in
this change since it will require more refactoring to add handling of
the IOException.

Thomas Wolf d7deda98d0 Skip ignored directories in FileTreeIterator
Make FileTreeIterator not enter ignored directories by default. We
only need to enter ignored directories if we do some operation against
git, and there is at least one tracked file underneath an ignored
directory.

Walking ignored directories should be avoided as much as possible as
it is a potential performance bottleneck. Some projects have a lot of
files or very deep hierarchies in ignored directories; walking those
may be costly (especially so on Windows). See for instance also bug
500106.

Provide a FileTreeIterator.setWalkIgnoredDirectories() operation to
force the iterator to iterate also through otherwise ignored
directories. Useful for tests (IgnoreNodeTest, CGitIgnoreTest), or
to implement things like "git ls-files --ignored".

Add tests in DirCacheCheckoutTest, and amend IndexDiffTest to test a
little bit more.

Jonathan Tan adc73c4ba1 Teach UploadPack basic "fetch" command
Add basic support for the "fetch" command in the fetch-pack/upload-pack
protocol v2. This patch teaches "have" and "done".

The protocol specification (Documentation/technical/protocol-v2.txt in
the Git project) states:

    want <oid>
	Indicates to the server an object which the client wants to
	retrieve.  Wants can be anything and are not limited to
	advertised objects.

It is unspecified whether the server should respect the
uploadpack.allowtipsha1inwant option etc. when serving packfiles. This
patch is conservative in that the server respects them.

Jonathan Tan 2661bc0813 Implement protocol v2 with no capabilities in UploadPack
Add initial support for protocol v2 of the fetch-pack/upload-pack
protocol. This protocol is described in the Git project in
"Documentation/technical/protocol-v2.txt".

This patch adds support for protocol v2 (without any capabilities) to
UploadPack. Adaptations of callers to make use of this support will
come in subsequent patches.

[jn: split from a larger patch; tweaked the API to make UploadPack
 handle parsing the extra parameters and config instead of requiring
 each caller to do such parsing]

Jonathan Tan 75b0703692 PacketLineIn, PacketLineOut: Add support for delim-pkt
Most pkt-lines (data-pkts) have the form

	pkt-len pkt-payload

where pkt-len is a string of 4 hexadecimal digits representing the
size in bytes of the pkt-line.  Since this size includes the size of
the pkt-len, no data-pkt has a length less than 4.

A pkt-line with a length field less than 4 can thus be used for
other purposes.  In Git protocol v1, the only such pkt-line was

	flush-pkt = "0000"

which was used to mark the end of a stream.  Protocol v2 (see
Documentation/technical/protocol-v2.txt in git.git) introduces a
second special pkt-line type:

	delim-pkt = "0001"

used to mark the end of a section within a stream, for example to
separate capabilities from the content of a command.

[jn: split out from a larger patch that made use of this support]

Jonathan Tan 4faec31c0a Add RefDatabase#getRefsByPrefix method
The existing RefDatabase#getRefs abstract method (to be implemented by
ref database backends) has the following issues:

 - It returns a map with a key (the name of the ref with the prefix
   removed) which is potentially superfluous (it can be derived by the
   caller if need be) and confusing (in that the prefix is removed).
 - The prefix is required to end with a '/', but some backends (e.g.
   reftable) have fast search by prefix regardless of what the last
   character of the prefix is.

Add a new method #getRefsByPrefix that does not have these issues. This
is non-abstract with a default implementation that uses #getRefs (for
backwards compatibility), but ref database backends can reimplement it.

This also prepares for supporting "ref-prefix" in the "ls-refs" command
in the fetch-pack/upload-pack protocol v2, which does not require that
the prefix end with a '/'.

David Pursehouse 5b0129641e Merge "Push: Ensure ref updates are processed in input order" 2018-04-13 17:43:12 -04:00
Dave Borowitz 29fc7e87c6 Push: Ensure ref updates are processed in input order
Various places on the client side of the push were creating unordered
maps and sets of ref names, resulting in ReceivePack processing commands
in an order other than what the client provided. This is normally not
problematic for clients, who don't typically care about the order in
which ref updates are applied to the storage layer.

However, it does make it difficult to write deterministic tests of
ReceivePack or hooks whose output depends on the order in which commands
are processed, for example if informational per-ref messages are written
to a sideband.[1]

Add a test that ensures the ordering of commands both internally in
ReceivePack and in the output PushResult.
