Acquire file lock "gc.pid" before running gc

Git guards gc by locking a lock file "gc.pid" before starting execution.
The lock file contains the pid and hostname of the process holding the
lock. Git tries to kill the process holding that lock if the lock file
wasn't modified in the last 12 hours and was started from the same host.

Teach JGit to acquire this lock before running gc but skip execution if
another process already holds the lock. Killing the other process could
be undesired if it's a long running application.

If the lock file wasn't modified in the last 12 hours try to lock it and
run gc if locking succeeds.

Register a shutdown hook for the lock file to ensure it is cleaned up if
the process is gracefully killed.

Shortcut during git fetch for avoiding looping through all local refs

The FetchProcess needs to verify that all the refs received point
to objects that are reachable from the local refs, which could be
very expensive but is needed to avoid missing objects exceptions
because of broken chains.

When the local repository has a lot of refs (e.g. millions) and the
client is fetching a non-commit object (e.g. refs/sequences/changes in
Gerrit) the reachability check on all local refs can be very expensive
compared to the time to fetch the remote ref.

Example for a 2M refs repository:
- fetching a single non-commit object: 50ms
- checking the reachability of local refs: 30s

A ref pointing to a non-commit object doesn't have any parent or
successor objects, hence would never need to have a reachability check
done. Skipping the askForIsComplete() altogether would save the 30s
time spent in an unnecessary phase.

Allow the exclusions of refs prefixes from bitmap

When running a GC.repack() against a repository with over one
thousands of refs/heads and tens of millions of ObjectIds,
the calculation of all bitmaps associated with all the refs
would result in an unreasonable big file that would take up to
several hours to compute.

Test scenario: repo with 2500 heads / 10M obj Intel Xeon E5-2680 2.5GHz
Before this change: 20 mins
After this change and 2300 heads excluded: 10 mins (90s for bitmap)

Having such a large bitmap file is also slow in the runtime
processing and have negligible or even negative benefits, because
the time lost in reading and decompressing the bitmap in memory
would not be compensated by the time saved by using it.

It is key to preserve the bitmaps for those refs that are mostly
used in clone/fetch and give the ability to exlude some refs
prefixes that are known to be less frequently accessed, even
though they may actually be actively written.

Example: Gerrit sandbox branches may even be actively
used and selected automatically because its commits are very
recent, however, they may bloat the bitmap, making it ineffective.

A mono-repo with tens of thousands of developers may have
a relatively small number of active branches where the
CI/CD jobs are continuously fetching/cloning the code. However,
because Gerrit allows the use of sandbox branches, the
total number of refs/heads may be even tens to hundred
thousands.

PackWriterBitmapPreparer: do not include annotated tags in bitmap

The annotated tags should be excluded from the bitmap associated
with the heads-only packfile. However, this was not happening
because of the check of exclusion of the peeled object instead
of the objectId to be excluded from the bitmap.

Sample use-case:

refs/heads/main
  ^
  |
 commit1 <-- commit2 <- annotated-tag1 <- tag1
  ^
  |
 commit0

When creating a bitmap for the above commit graph, before this
change all the commits are included (3 bitmaps), which is
incorrect, because all commits reachable from annotated tags
should not be included.

The heads-only bitmap should include only commit0 and commit1
but because PackWriterBitPreparer was checking for the peeled
pointer of tag1 to be excluded (commit2) which was not found in
the list of tags to exclude (annotated-tag1), the commit2 was
included, even if it wasn't reachable only from the head.

Add an additional check for exclusion of the original objectId
for allowing the exclusion of annotated tags and their pointed
commits. Add one specific test associated with an annotated tag
for making sure that this use-case is covered also.

Example repository benchmark for measuring the improvement:
# refs: 400k (2k heads, 88k tags, 310k changes)
# objects: 11M (88k of them are annotate tags)
# packfiles: 2.7G

Do not create reflog for remote tracking branches during clone

When using JGit on a non-bare repository, the CloneCommand
it previously created local reflogs for all branches including remote
tracking ones, causing the generation of a potentially large
number of files on the local filesystem.

The creation of the remote-tracking branches (refs/remotes/*) during
clone is not an issue for the local filesystem because all of them are
stored in a single packed-refs file. However, the creation of a large
number of ref logs on a local filesystem IS an issue because it
may not be tuned or initialised in term of inodes to contain a very
large number of files.

When a user (or a CI system) performs the CloneCommand against
a potentially large repository (e.g., millions of branches), it is
interested in working or validating a single branch or tag and is
unlikely to work with all the remote-tracking branches.
The eager creation of a reflogs for all the remote-tracking branches is
not just a performance issue but may also compromise the ability to
use JGit for cloning a large repository.

The behaviour implemented in this change is also consistent with the
optimisation done in the C code-base [1].

We differentiate between clone and fetch commands using --branch
<initialBranch> option, that is only available in clone command,
and is set as HEAD per default.

UploadPack: do not check reachability of visible SHA1s

When JGit needs to serve a Git client requesting SHA1s
during the want phase, it needs to make a full reachability
check from the advertised refs to the ones requested to
keep all objects in the correct scope of confidentiality
allowed by the avertised refs.

The check is also performed when the SHA1 corresponds to
one of the tips of the advertised refs which is a waste of
resources.

Example:

fetch> ref-prefix refs/heads/foo
fetch< 900505eb8ce8ced2a1757906da1b25c357b9654e refs/heads/foo
fetch< 0000
fetch> command=fetch
fetch> 0001
fetch> thin-pack
fetch> ofs-delta
fetch> want 900505eb8ce8ced2a1757906da1b25c357b9654e

The SHA1 in the want is the tip of refs/heads/foo and therefore
the full reachability check can be shortened and resolved more
quickly.

HTTP Smart: set correct HTTP status on error

Previous behavior was that status code was automatically set to 200
regardless of reported status and according to HTTP Smart protocol[1]:

  If there is no repository at $GIT_URL, or the resource pointed to by
  a location matching $GIT_URL does not exist, the server MUST NOT
  respond with 200 OK response. A server SHOULD respond with
  404 Not Found, 410 Gone, or any other suitable HTTP status code which
  does not imply the resource exists as requested.

Since the jgit HTTP client isn't able to handle reading content from a
response reporting an error (calling HttpURLConnection#getInputStream
on a "failed" connection throws an exception and the internal interface
HttpConnection does not expose HttpURLConnection#getErrorStream) the
SmartClientSmartServerTest needed to be rewritten to expect the generic

2 years ago[checkout] Use .gitattributes from the commit to be checked out 66/190766/4
Thomas Wolf [Sun, 13 Feb 2022 22:30:36 +0000 (23:30 +0100)]
[checkout] Use .gitattributes from the commit to be checked out

JGit used only one set of attributes constructed from the global and
info attributes, plus the attributes from working tree, index, and
HEAD.

These attributes must be used to determine whether the working tree is
dirty.

But for actually checking out a file, one must use the attributes from
global, info, and *the commit to be checked out*. Otherwise one may not
pick up definitions that are only in the .gitattributes of the commit
to be checked out or that are changed in that commit with respect to
the attributes currently in HEAD, the index, or the working tree.

Maintain in TreeWalk different Attributes per tree, and add operations
to determine EOL handling and smudge filters per tree.

Use the new methods in DirCacheCheckout and ResolveMerger. Note that
merging in JGit actually used the attributes from the base, not those
from ours, which looks dubious at least. It now uses those from ours,
and for checking out the ones from theirs.

The canBeContentMerged() determination was also done from the base
attributes, and is newly done from the ours attributes. Possibly this
should take into account all three attributes, and only if all three
agree the item can be content merged, a content merge should be
attempted? (What if the binary/text setting changes between base, ours,
or theirs?)

Also note that JGit attempts to perform content merges on non-binary
LFS files; there it used the filter attribute from base, too, even for
the ours and theirs versions. Newly it takes the filter attribute from
the correct tree. I'm not convinced doing content merges on potentially
huge files like LFS files is really a good idea.

Add tests in FilterCommandsTest and LfsGitTest to verify the behavior.

Open question: using index and working tree as fallback for the
attributes of ours (assuming it is HEAD) is OK. But does it also make
sense for base and theirs in merging?

Simplify implementation of WorkingTreeIterator

All the filtering in WorkingTreeIterator is for check-in, i.e., clean
filtering. The implementation was in some parts too general, passing
around an OperationType. But since it's always CHECKIN_OP, that's not
actually necessary.

Transport: load all refs only if push refspecs have wildcards

There is no need to load all refs if there are no wildcard push
refspecs. Load them lazily on the first wildcard refspec encountered
instead of loading them up-front.
