"git cherry-pick -m1" was forbidden when picking a non-merge
commit, even though there _is_ parent number 1 for such a commit.
This was done to avoid mistakes back when "cherry-pick" was about
picking a single commit, but is no longer useful with "cherry-pick"
that can pick a range of commits. Now the "-m$num" option is
allowed when picking any commit, as long as $num names an existing
parent of the commit.
Technically this is a backward incompatible change; hopefully
nobody is relying on the error-checking behaviour.

Updating a shelved P4 changelist where one or more files have
been moved or copied does not work. Add a test for this.
The problem is that P4 requires a complete list of the files being
changed, and move/copy only includes the _source_ in the case of
updating a shelved changelist. This results in errors from Perforce
such as:
//depot/src - needs tofile //depot/dst
Submit aborted -- fix problems then use 'p4 submit -c 1234'

Implement positive values for <depth> in the tree:<depth> filter. The
exact semantics are described in Documentation/rev-list-options.txt.
The long-term goal at the end of this is to allow a partial clone to
eagerly fetch an entire directory of files by fetching a tree and
specifying <depth>=1. This, for instance, would make a build operation
fast and convenient. It is fast because the partial clone does not need
to fetch each file individually, and convenient because the user does
not need to supply a sparse-checkout specification.
Another way of considering this feature is as a way to reduce
round-trips, since the client can get any number of levels of
directories in a single request, rather than wait for each level of tree
objects to come back, whose entries are used to construct a new request.

Commit 685fbd3291 ("fetch-pack: perform a fetch using v2", 2018-03-15)
attempted to teach Git deepen-relative in protocol v2 (among other
things), but it didn't work:
(1) fetch-pack.c needs to emit "deepen-relative".
(2) upload-pack.c needs to ensure that the correct deepen_relative
variable is passed to deepen() (there are two - the static variable
and the one in struct upload_pack_data).
(3) Before deepen() computes the list of reachable shallows, it first
needs to mark all "our" refs as OUR_REF. v2 currently does not do
this, because unlike v0, it is not needed otherwise.
Fix all this and include a test demonstrating that it works now. For
(2), the static variable deepen_relative is also eliminated, removing a
source of confusion.

When fetching using protocol v2, the remote may send a "shallow-info"
section if the client is shallow. If so, Git as the client currently
takes the shallow file lock, even if the "shallow-info" section is
empty.
This is not a problem except that Git does not support taking the
shallow file lock after modifying the shallow file, because
is_repository_shallow() stores information that is never cleared. And
this take-after-modify occurs when Git does a tag-following fetch from a
shallow repository on a transport that does not support tag following
(since in this case, 2 fetches are performed).
To solve this issue, take the shallow file lock (and perform all other
shallow processing) only if the "shallow-info" section is non-empty;
otherwise, behave as if it were empty.
A full solution (probably, ensuring that any action of committing
shallow file locks also includes clearing the information stored by
is_repository_shallow()) would solve the issue without need for this
patch, but this patch is independently useful (as an optimization to
prevent writing a file in an unnecessary case), hence why I wrote it. I
have included a NEEDSWORK outlining the full solution.

When the scaffolding for protocol version 2 was initially added in
8f6982b4e1 ("protocol: introduce enum protocol_version value
protocol_v2", 2018-03-14). As seen in:
git log -p -G'support for protocol v2 not implemented yet' --full-diff --reverse v2.17.0..v2.20.0
Many of those scaffolding "die" placeholders were removed, but we
hadn't gotten around to fetch-pack yet.
The test here for "fetch refs from cmdline" is very minimal. There's
much better coverage when running the entire test suite under the WIP
GIT_TEST_PROTOCOL_VERSION=2 mode[1], we should ideally have better
coverage without needing to invoke a special test mode.

In the v2 protocol, upload-pack's advertisement has been moved to the
"ls-refs" command. That command does not respect hidden-ref config (like
transfer.hiderefs) at all, and advertises everything.
While there are some features that are not supported in v2 (e.g., v2
always allows fetching any sha1 without respect to advertisements), the
lack of this feature is not documented and is likely just a bug. Let's
make it work, as otherwise upgrading a server to a v2-capable git will
start exposing these refs that the repository admin has asked to remain
hidden.
Note that we assume we're operating on behalf of a fetch here, since
that's the only thing implemented in v2 at this point. See the in-code
comment. We'll have to figure out how this works when the v2 push
protocol is designed (both here in ls-refs, but also rejecting updates
to hidden refs).

When using --color-moved-ws=allow-indentation-change allow lines with
the same indentation change to be grouped across blank lines. For now
this only works if the blank lines have been moved as well, not for
blocks that have just had their indentation changed.
This completes the changes to the implementation of
--color-moved=allow-indentation-change. Running
git diff --color-moved=allow-indentation-change v2.18.0 v2.19.0
now takes 5.0s. This is a saving of 41% from 8.5s for the optimized
version of the previous implementation and 66% from the original which

Currently diff --color-moved-ws=allow-indentation-change does not
support indentation that contains a mix of tabs and spaces. For
example in commit 546f70f377 ("convert.h: drop 'extern' from function
declaration", 2018-06-30) the function parameters in the following
lines are not colored as moved [1].
-extern int stream_filter(struct stream_filter *,
- const char *input, size_t *isize_p,
- char *output, size_t *osize_p);
+int stream_filter(struct stream_filter *,
+ const char *input, size_t *isize_p,
+ char *output, size_t *osize_p);
This commit changes the way the indentation is handled to track the
visual size of the indentation rather than the characters in the
indentation. This has the benefit that any whitespace errors do not
interfer with the move detection (the whitespace errors will still be
highlighted according to --ws-error-highlight). During the discussion
of this feature there were concerns about the correct detection of
indentation for python. However those concerns apply whether or not
we're detecting moved lines so no attempt is made to determine if the
indentation is 'pythonic'.
[1] Note that before the commit to fix the erroneous coloring of moved
lines each line was colored as a different block, since that commit
they are uncolored.

Currently when using --color-moved=zebra the color of moved blocks
depends on the number of lines separating them. This means that adding
an odd number of unmoved lines between blocks that are already separated
by one or more unmoved lines will change the color of subsequent moved
blocks. This does not make much sense as the blocks were already
separated by unmoved lines and causes problems when adding lines to test
cases.
Fix this by only using the alternate colors for adjacent moved blocks.
