"git clone" that clones from SHA-1 repository, while
GIT_DEFAULT_HASH set to use SHA-256 already, resulted in an

Protocol v2 became the default in v2.26.0 via 684ceae32d (fetch: default
to protocol version 2, 2019-12-23). More widespread use turned up a
regression in negotiation. That was fixed in v2.27.0 via 4fa3f00abb
(fetch-pack: in protocol v2, in_vain only after ACK, 2020-04-27), but we
also reverted the default to v0 as a precuation in 11c7f2a30b (Revert
"fetch: default to protocol version 2", 2020-04-22).
In v2.28.0, we re-enabled it for experimental users with 3697caf4b9
(config: let feature.experimental imply protocol.version=2, 2020-05-20)
and haven't heard any complaints. v2.28 has only been out for 2 months,
but I'd generally expect people turning on feature.experimental to also
stay pretty up-to-date. So we're not likely to collect much more data by
waiting. In addition, we have no further reports from people running
v2.26.0, and of course some people have been setting protocol.version
manually for ages.
Let's move forward with v2 as the default again. It's possible there are
still lurking bugs, but we won't know until it gets more widespread use.
And we can find and squash them just like any other bug at this point.

The update sample hook has the zero OID hardcoded as 40 zeros. However,
with the introduction of SHA-256 support, this assumption no longer
holds true. Replace the hardcoded $z40 with a call to
git hash-object --stdin </dev/null | tr '[0-9a-f]' '0'
so the sample hook becomes hash-agnostic.

The preferred form for a command substitution is $() over ``. Use this
form for the command substitution in the sample hook.
The preferred form for conditional tests is to use `test` over [].
Replace [] with `test`.
Finally, replace all instances of "sha" with "oid".

If a user is cloning a SHA-1 repository with GIT_DEFAULT_HASH set to
"sha256", then we can end up with a repository where the repository
format version is 0 but the extensions.objectformat key is set to
"sha256". This is both wrong (the user has a SHA-1 repository) and
nonfunctional (because the extension cannot be used in a v0 repository).
This happens because in a clone, we initially set up the repository, and
then change its algorithm based on what the remote side tells us it's
using. We've initially set up the repository as SHA-256 in this case,
and then later on reset the repository version without clearing the
extension.
We could just always set the extension in this case, but that would mean
that our SHA-1 repositories weren't compatible with older Git versions,
even though there's no reason why they shouldn't be. And we also don't
want to initialize the repository as SHA-1 initially, since that means
if we're cloning an empty repository, we'll have failed to honor the
GIT_DEFAULT_HASH variable and will end up with a SHA-1 repository, not a
SHA-256 repository.
Neither of those are appealing, so let's tell the repository
initialization code if we're doing a reinit like this, and if so, to
clear the extension if we're using SHA-1. This makes sure we produce a
valid and functional repository and doesn't break any of our other use
cases.

We try to flush the output from diff-highlight whenever we see a blank
line. That lets you see the output for each commit as soon as it is
generated, even if Git is still chugging away at a diff, or traversing
to find the next commit.
However, our "blank line" match checks length($_). That won't ever be
true, because we haven't chomped the line ending. As a result, we never
flush. Instead, let's use a simple regex which handles line endings in
with the end-of-line marker.
This has been broken since the initial version in 927a13fe87 (contrib:
add diff highlight script, 2011-10-18). Probably nobody noticed because:
- most output is big enough, or comes fast enough, that it flushes
anyway. And it can be difficult to notice the difference between
"show a commit, then pause" and "pause, then show two commits". I
only noticed because I was viewing "git log" output on a repo with a
very slow textconv filter.
- if stdout is going to the terminal (and not another pager like
less), then the flush isn't necessary. So any manual testing would
show it appearing to work.
You can easily see the difference with something like:
echo '* diff=slow' >>.gitattributes
git -c diff.slow.textconv='sleep 1; cat' \
-c pager.log='diff-highlight | less' \
log -p
That should generate one commit every second or so (more if it touches
multiple files), but without this patch it waits for many seconds before
generating several pages of output.

Users frequently have problems where two filenames differ only in case,
causing one of those files to show up consistently as being modified.
Let's add a FAQ entry that explains how to deal with that.
In addition, let's explain another common case where files are
consistently modified, which is when files using a smudge or clean
filter have not been run through that filter. Explain the way to fix
this as well.

A common scenario is for a user to apply a change to one branch and
cherry-pick it into another, then later revert it in the first branch.
This results in the change being present when the two branches are
merged, which is confusing to many users.
We already have documentation for how this works in `git merge`, but it
is clear from the frequency with which this is asked that it's hard to
grasp. We also don't explain to users that they are better off doing a
rebase in this case, which will do what they intended. Let's add an
entry to the FAQ telling users what's happening and advising them to use
rebase here.

In many projects, squash merges are commonly used, primarily to keep a
tidy history in the face of developers who do not use logically
independent, bisectable commits. As common as this is, this tends to
cause significant problems when squash merges are used to merge
long-running branches due to the lack of any new merge bases. Even very
experienced developers may make this mistake, so let's add a FAQ entry
explaining why this is problematic and explaining that regular merge
commits should be used to merge two long-running branches.

The refs update commands can be sent to the server side in two different
ways: GPG-signed or unsigned. We should run these two operations in the
same "Finally, tell the other end!" code block, but they are seperated
by the "Clear the status for each ref" code block. This will result in
a slight performance loss, because the failed atomic push will still
perform unnecessary preparations for shallow advertise and GPG-signed
commands buffers, and user may have to be bothered by the (possible) GPG
passphrase input when there is nothing to sign.
Add a new test case to t5534 to ensure GPG will not be called when the
GPG-signed atomic push fails.
