On Windows, it is possible to embed additional metadata into an
executable by linking in a "manifest", i.e. an XML document that
describes capabilities and requirements (such as minimum or maximum
Windows version). These XML documents are expected to be stored in
`.manifest` files.
At least _some_ Visual Studio versions auto-generate `.manifest` files
when none is specified explicitly, therefore we used to ask Git to
ignore them.
However, we do have a beautiful `.manifest` file now:
`compat/win32/git.manifest`, so neither does Visual Studio auto-generate
a manifest for us, nor do we want Git to ignore the `.manifest` files
anymore.

When applying multiple patches with git am, or when rebasing using the
am backend, it's possible that one of our patches has updated a
gitattributes file. Currently, we cache this information, so if a
file in a subsequent patch has attributes applied, the file will be
written out with the attributes in place as of the time we started the
rebase or am operation, not with the attributes applied by the previous
patch. This problem does not occur when using the -m or -i flags to
rebase.
To ensure we write the correct data into the working tree, expire the
cache after each patch that touches a path ending in ".gitattributes".
Since we load these attributes in multiple separate files, we must
expire them accordingly.
Verify that both the am and rebase code paths work correctly, including
the conflict marker size with am -3.

Commit e70a3030e7 ("fetch: do not list refs if fetching only hashes",
2018-10-07) and its ancestors taught Git, as an optimization, to skip
the ls-refs step when it is not necessary during a protocol v2 fetch
(for example, when lazy fetching a missing object in a partial clone, or
when running "git fetch --no-tags <remote> <SHA-1>"). But that was only
done for natively supported protocols; in particular, HTTP was not
supported.
Teach Git to skip ls-refs when using remote helpers that support connect
or stateless-connect. To do this, fetch() is made an acceptable entry
point. Because fetch() can now be the first function in the vtable
called, "get_helper(transport);" has to be added to the beginning of
that function to set the transport up (if not yet set up) before
process_connect() is invoked.
When fetch() is called, the transport could be taken over (this happens
if "connect" or "stateless-connect" is successfully run without any
"fallback" response), or not. If the transport is taken over, execution
continues like execution for natively supported protocols
(fetch_refs_via_pack() is executed, which will fetch refs using ls-refs
if needed). If not, the remote helper interface will invoke
get_refs_list() if it hasn't been invoked yet, preserving existing
behavior.

In t0021.15 one of the things we are checking is that the clean filter
is run when checking out empty-branch. The clean filter needs to be
run to make sure there are no modifications on the file system for the
test.r file, and thus it isn't dangerous to overwrite it.
However in the current test setup it is not always necessary to run
the clean filter, and thus the test sometimes fails, as debug.log
isn't written.
This happens when test.r has an older mtime than the index itself.
That mtime is also recorded as stat data for test.r in the index, and
based on the heuristic we're using for index entries, git correctly
assumes this file is up-to-date.
Usually this test succeeds because the mtime of test.r is the same as
the mtime of the index. In this case test.r is racily clean, so git
actually checks the contents, for which the clean filter is run.
Fix the test by updating the mtime of test.r, so git is forced to
check the contents of the file, and the clean filter is run as the
test expects.

With rename detection enabled the line-level log is able to trace the
evolution of line ranges across whole-file renames [1]. Alas, to
achieve that it uses the diff machinery very inefficiently, making the
operation very slow [2]. And since rename detection is enabled by
default, the line-level log is very slow by default.
When the line-level log processes a commit with rename detection
enabled, it currently does the following (see queue_diffs()):
1. Computes a full tree diff between the commit and (one of) its
parent(s), i.e. invokes diff_tree_oid() with an empty
'diffopt->pathspec'.
2. Checks whether any paths in the line ranges were modified.
3. Checks whether any modified paths in the line ranges are missing
in the parent commit's tree.
4. If there is such a missing path, then calls diffcore_std() to
figure out whether the path was indeed renamed based on the
previously computed full tree diff.
5. Continues doing stuff that are unrelated to the slowness.
So basically the line-level log computes a full tree diff for each
commit-parent pair in step (1) to be used for rename detection in step
(4) in the off chance that an interesting path is missing from the
parent.
Avoid these expensive and mostly unnecessary full tree diffs by
limiting the diffs to paths in the line ranges. This is much cheaper,
and makes step (2) unnecessary. If it turns out that an interesting
path is missing from the parent, then fall back and compute a full
tree diff, so the rename detection will still work.
Care must be taken when to update the pathspec used to limit the diff
in case of renames. A path might be renamed on one branch and
modified on several parallel running branches, and while processing
commits on these branches the line-level log might have to alternate
between looking at a path's new and old name. However, at any one
time there is only a single 'diffopt->pathspec'.
So add a step (0) to the above to ensure that the paths in the
pathspec match the paths in the line ranges associated with the
currently processed commit, and re-parse the pathspec from the paths
in the line ranges if they differ.
The new test cases include a specially crafted piece of history with
two merged branches and two files, where each branch modifies both
files, renames on of them, and then modifies both again. Then two
separate 'git log -L' invocations check the line-level log of each of
those two files, which ensures that at least one of those invocations
have to do that back-and-forth between the file's old and new name (no
matter which branch is traversed first). 't/t4211-line-log.sh'
already contains two tests involving renames, they don't don't trigger
this back-and-forth.
Avoiding these unnecessary full tree diffs can have huge impact on
performance, especially in big repositories with big trees and mergy
history. Tracing the evolution of a function through the whole
history:
# git.git
$ time git --no-pager log -L:read_alternate_refs:sha1-file.c v2.23.0
Before:
real 0m8.874s
user 0m8.816s
sys 0m0.057s
After:
real 0m2.516s
user 0m2.456s

# linux.git
$ time ~/src/git/git --no-pager log \
-L:build_restore_work_registers:arch/mips/mm/tlbex.c v5.2

user 3m48.041s
sys 0m0.300s
After:
real 0m2.599s
user 0m2.466s
sys 0m0.157s
That's just over 88x speedup.
[1] Line-level log's rename following is quite similar to 'git log
--follow path', with the notable differences that it does handle
multiple paths at once as well, and that it doesn't show the
commit performing the rename if it's an exact rename.
[2] This slowness might not have been apparent initially, because back
when the line-level log feature was introduced rename detection
was not yet enabled by default; 12da1d1f6f (Implement line-history
search (git log -L), 2013-03-28) and 5404c116aa (diff: activate
