We observed the following issue:
$ git tag -a v1.0 -m v1.0
$ git push origin tag v1.0
$ git ls-remote origin v1.0^{}
... empty result ...
On the server (Gerrit) side run git-gc to pack the refs:
$ git gc
Repeat the ls-remote from the client and the result is correct:
$ git ls-remote origin v1.0^{}

Unfortunately, the existing UploadPackTest didn't reveal this issue
although it provided the test case needed to do so: testV2LsRefsPeel.
This is because The UploadPackTest uses InMemoryRepository which
internally uses Dfs* implementations. The issue is only reproducible
when using the FileRepository.
It is a non-trivial task to refactor the UploadPackTest to work against
both InMemoryRepository and FileRepository and this change is not trying
to do that. This change creates a new test:
UploadPackLsRefsFileRepositoryTest and copies the necesssary code from
the UploadPackTest.

Transitive Relation Definition:
On the DAG of commit history, if A can reach B, C can reach A, then C
can reach B.
Example:
As is shown in the graph below:
1 - 2 - 3 - 4 (side)
\
5 - 6^ (master) - 7 (topic)
Find out which branches is 2 merged into:
After we calculated that master contains 2, we can mark 6 as TEMP_MARK
to avoid unwanted walks.
When we want to figure out if 2 is merge into the topic, the traversal
path would be [7, 6] instead of [7, 6, 5, 3, 2].
Test:
This change can significantly improve performance for tags.
On a copy of the Linux repository, the command 'git tag --contains
<commit>' had the following performance improvement:
commit | Before | After | Rel %
47a44d27ca | 29251ms | 6687ms | -77%
90327e7dff | 21388ms | 6256ms | -70%
f85fac0efa | 11150ms | 7338ms | -34%
The current version ignores tags, even though the tag is a type of
the ref.
Follow-up commits I'll fix it.

The reftable format is a block based format, but allows for variably
sized blocks. This obviously happens for reflog blocks (which are zlib
compressed), but is also accepted for index blocks: In the spec, this
is motivated as
To achieve constant O(1) disk seeks for lookups the index must be
a single level, which is permitted to exceed the file's
configured block size, but not the format's max block size of
15.99 MiB.
Hence, when parsing a block, one cannot be sure of its exact size:
after reading a default-size block (eg. 4kb), the block header may
state that the block is in fact larger.
Before, the code would mark the block as `truncated`, noting
// Its OK during sequential scan for an index block to have been
// partially read and be truncated in-memory. This happens when
// the index block is larger than the file's blockSize. Caller
// will break out of its scan loop once it sees the blockType.
This looks like either
* a remnant of never-implemented functionality. There is no reason to
ever sequentially scan an index block.
* alluding to sequential scan of the data blocks before the index
blocks (eg. scanning refs, which ends when we find the first ref index
block, and we can then ignore the index block).
This comment is followed by code that populates the
restartTbl/restartCnt fields relative to the (possibly truncated)
buffer. If the buffer is truncated, this essentially reads garbage,
leading to OOB array access when using the index block.
Fix this by dropping the truncated logic and issuing a second read if
the first read was short.
Add a test.
We have never observed this failure scenario at Google. We use 64kb
blocksize, which requires us to need fewer index entries. The reftable
spec mentions an Android repo of size 36M. With 64kb blocks, that's
just 562 index entries. Even with historical growth, we are long from
requiring an index whose size exceeds a single block.
When adding the analogous test for seeking refs, there was no failure.
This points to another possibility which is that the code tries to
avoid writing large index blocks for refs.
I did not investigate further which one it is.

Sometimes it is useful to obtain metadata associated with an object
without the need to first download it locally. This is specially useful
when using partial clones.
This change implements the object-info capability that allows clients to
query the remote server for object metadata (currently only size). This
is a backport of the same capability that was recently added to the Git
project a2ba162cda (object-info: support for retrieving object info,
2021-04-20).

We currently cannot use hamcrest 2.2 and assertj 3.20.2 (which requires
hamcrest 2.2) in egit tests since other Eclipse dependencies (e.g.
swtbot) require hamcrest 1.1.
Hence relax version range for these components in jgit so that jgit
tests also work when using the egit target platform.

and update
- assertj to 3.20.2.v20210706-1104
- hamcrest to 2.2.0.v20210711-0821
- classes which were in org.hamcrest.core 1.3 and org.hamcrest.library
1.3 were all moved to org.hamcrest in 2.2
- the annotation org.hamcrest.Factory was removed and is no longer
needed
- junit 4.13 requires hamcrest-core and hamcrest-library 1.3 therefore
keep them in the target platform

The search for reuse phase for *all* the objects scans *all*
the packfiles, looking for the best candidate to serve back to the
client.
This can lead to an expensive operation when the number of
packfiles and objects is high.

on this search.

When reading loose objects over NFS it is possible that the OS syscall
would fail with ESTALE errors: This happens when the open file
descriptor no longer refers to a valid file.
Notoriously it is possible to hit this scenario when git data is shared
among multiple clients, for example by multiple gerrit instances in HA.
If one of the two clients performs a GC operation that would cause the
packing and then the pruning of loose objects, the other client might
still hold a reference to those objects, which would cause an exception
to bubble up the stack.
The Linux NFS FAQ[1] (at point A.10), suggests that the proper way to
handle such ESTALE scenarios is to:
"[...] close the file or directory where the error occurred, and reopen
it so the NFS client can resolve the pathname again and retrieve the new
file handle."
In case of a stale file handle exception, we now attempt to read the
loose object again (up to 5 times), until we either succeed or encounter
a FileNotFoundException, in which case the search can continue to
Packfiles and alternates.
The limit of 5 provides an arbitrary upper bounds that is consistent to
the one chosen when handling stale file handles for packed-refs
files (see [2] for context).

On a subtree, a PathSuffixFilter must return -1 ("indeterminate"),
not 0 ("include"), otherwise negation goes wrong: an indeterminate
result (-1) is passed on, but a decision (0/1) is inverted.
As a result a negated PathSuffixFilter would skip all folders.
