`usage` tries to call $0, which might very well be "./doc-diff", so if
we `cd_to_toplevel` before calling `usage`, we'll end with an error to
the effect of "./doc-diff: not found" rather than a friendly `doc-diff
-h` output. This regressed in ad51743007 ("doc-diff: add --clean mode to
remove temporary working gunk", 2018-08-31) where we moved the call to
`cd_to_toplevel` to much earlier.
A general fix might be to teach git-sh-setup to save away the absolute
path for $0 and then use that, instead. I'm not aware of any portable
way of doing that, see, e.g., d2addc3b96 ("t7800: readlink may not be
available", 2016-05-31).
An early version of this patch moved `cd_to_toplevel` back to where it
was before ad51743007 and taught the "--clean" code to cd on its own.
But let's try instead to get rid of the cd-ing entirely. We don't really
need it and we can work with absolute paths instead. There's just one
use of $PWD that we need to adjust by simply dropping it.

The documentation saying that diff-tree didn't support anything except
literal prefixes hasn't been true since
d38f28093e ("tree_entry_interesting(): support wildcard matching",
2010-12-15), but this documentation was not updated at the time.
Since this command uses pathspecs like most other commands, there's no
need to show examples of how the various "cmd <revs> <paths>"
invocations work.
Furthermore, the "git diff-tree --abbrev 5319e4" example shown here
never worked. We'd ended up with that through a combination of
62b42d3487 ("docs: fix some antique example output", 2011-05-26) and
ac4e086929 ("Adjust core-git documentation to more recent Linus GIT.",
2005-05-05), but "git diff-tree <tree>" was always invalid.

Users who want UTF-16 files in the working tree set the .gitattributes
like this:
test.txt working-tree-encoding=UTF-16
The unicode standard itself defines 3 allowed ways how to encode UTF-16.
The following 3 versions convert all back to 'g' 'i' 't' in UTF-8:
a) UTF-16, without BOM, big endian:
$ printf "\000g\000i\000t" | iconv -f UTF-16 -t UTF-8 | od -c
0000000 g i t
b) UTF-16, with BOM, little endian:
$ printf "\377\376g\000i\000t\000" | iconv -f UTF-16 -t UTF-8 | od -c
0000000 g i t
c) UTF-16, with BOM, big endian:
$ printf "\376\377\000g\000i\000t" | iconv -f UTF-16 -t UTF-8 | od -c
0000000 g i t
Git uses libiconv to convert from UTF-8 in the index into ITF-16 in the
working tree.
After a checkout, the resulting file has a BOM and is encoded in "UTF-16",
in the version (c) above.
This is what iconv generates, more details follow below.
iconv (and libiconv) can generate UTF-16, UTF-16LE or UTF-16BE:
d) UTF-16
$ printf 'git' | iconv -f UTF-8 -t UTF-16 | od -c
0000000 376 377 \0 g \0 i \0 t
e) UTF-16LE
$ printf 'git' | iconv -f UTF-8 -t UTF-16LE | od -c
0000000 g \0 i \0 t \0
f) UTF-16BE
$ printf 'git' | iconv -f UTF-8 -t UTF-16BE | od -c
0000000 \0 g \0 i \0 t
There is no way to generate version (b) from above in a Git working tree,
but that is what some applications need.
(All fully unicode aware applications should be able to read all 3 variants,
but in practise we are not there yet).
When producing UTF-16 as an output, iconv generates the big endian version
with a BOM. (big endian is probably chosen for historical reasons).
iconv can produce UTF-16 files with little endianess by using "UTF-16LE"
as encoding, and that file does not have a BOM.
Not all users (especially under Windows) are happy with this.
Some tools are not fully unicode aware and can only handle version (b).
Today there is no way to produce version (b) with iconv (or libiconv).
Looking into the history of iconv, it seems as if version (c) will
be used in all future iconv versions (for compatibility reasons).
Solve this dilemma and introduce a Git-specific "UTF-16LE-BOM".
libiconv can not handle the encoding, so Git pick it up, handles the BOM
and uses libiconv to convert the rest of the stream.
(UTF-16BE-BOM is added for consistency)

The word "property" is vague here. Let's spell out that we mean the path
must be marked with the text attribute.
While we're here, let's make the paragraph a little easier to read by
de-emphasizing the "when core.autocrlf is false" bit. Putting it in the
first sentence obscures the main content, and many readers won't care
about autocrlf (i.e., anyone who is just following the gitattributes(7)
advice, which mainly discusses "text" and "core.eol").

With this patch it is possible to launch git-instaweb by using
Python http.server CGI handler via `-d python` option.
git-instaweb generates a small wrapper around the http.server
(in GIT_DIR/gitweb/) that address a limitation of the CGI handler
where CGI scripts have to be in a cgi-bin subdirectory and
directory index can't be easily changed. To keep the implementation
small, gitweb is running on url `/cgi-bin/gitweb.cgi` and an automatic
redirection is done when opening `/`.
The generated wrapper is compatible with both Python 2 and 3.
Python is by default installed on most modern Linux distributions
which enables running `git instaweb -d python` without needing
anything else.

Display date and time information in a format similar to how people
write dates in other contexts. If the year isn't specified then, the
reader infers the date is given is in the current year.
By not displaying the redundant information, the reader concentrates
on the information that is different. The patch reports relative dates
based on information inferred from the date on the machine running the
git command at the time the command is executed.
While the format is more useful to humans by dropping inferred
information, there is nothing that makes it actually human. If the
'relative' date format wasn't already implemented then using
'relative' would have been appropriate.

The optional 'Large Edge List' chunk of the commit graph file stores
parent information for commits with more than two parents, and the
names of most of the macros, variables, struct fields, and functions
related to this chunk contain the term "large edges", e.g.
write_graph_chunk_large_edges(). However, it's not a really great
term, as the edges to the second and subsequent parents stored in this
chunk are not any larger than the edges to the first and second
parents stored in the "main" 'Commit Data' chunk. It's the number of
edges, IOW number of parents, that is larger compared to non-merge and
"regular" two-parent merge commits. And indeed, two functions in
'commit-graph.c' have a local variable called 'num_extra_edges' that
refer to the same thing, and this "extra edges" term is much better at
describing these edges.
So let's rename all these references to "large edges" in macro,
variable, function, etc. names to "extra edges". There is a
GRAPH_OCTOPUS_EDGES_NEEDED macro as well; for the sake of consistency
rename it to GRAPH_EXTRA_EDGES_NEEDED.
We can do so safely without causing any incompatibility issues,
because the term "large edges" doesn't come up in the file format
itself in any form (the chunk's magic is {'E', 'D', 'G', 'E'}, there
is no 'L' in there), but only in the specification text. The string
"large edges", however, does come up in the output of 'git
commit-graph read' and in tests looking at its input, but that command
is explicitly documented as debugging aid, so we can change its output
and the affected tests safely.

The '--sparse' flag in 'git pack-objects' changes the algorithm
used to enumerate objects to one that is faster for individual
users pushing new objects that change only a small cone of the
working directory. The sparse algorithm is not recommended for a
server, which likely sends new objects that appear across the
entire working directory.
Create a 'pack.useSparse' setting that enables this new algorithm.
This allows 'git push' to use this algorithm without passing a
'--sparse' flag all the way through four levels of run_command()
calls.
If the '--no-sparse' flag is set, then this config setting is
overridden.

When creating a pack-file using 'git pack-objects --revs' we provide
a list of interesting and uninteresting commits. For example, a push
operation would make the local topic branch be interesting and the
known remote refs as uninteresting. We want to discover the set of
new objects to send to the server as a thin pack.
We walk these commits until we discover a frontier of commits such
that every commit walk starting at interesting commits ends in a root
commit or unintersting commit. We then need to discover which
non-commit objects are reachable from uninteresting commits. This
commit walk is not changing during this series.
The mark_edges_uninteresting() method in list-objects.c iterates on
the commit list and does the following:
* If the commit is UNINTERSTING, then mark its root tree and every
object it can reach as UNINTERESTING.
* If the commit is interesting, then mark the root tree of every
UNINTERSTING parent (and all objects that tree can reach) as
UNINTERSTING.
At the very end, we repeat the process on every commit directly
given to the revision walk from stdin. This helps ensure we properly
cover shallow commits that otherwise were not included in the
frontier.
The logic to recursively follow trees is in the
mark_tree_uninteresting() method in revision.c. The algorithm avoids
duplicate work by not recursing into trees that are already marked
UNINTERSTING.
Add a new 'sparse' option to the mark_edges_uninteresting() method
that performs this logic in a slightly different way. As we iterate
over the commits, we add all of the root trees to an oidset. Then,
call mark_trees_uninteresting_sparse() on that oidset. Note that we
include interesting trees in this process. The current implementation
of mark_trees_unintersting_sparse() will walk the same trees as
the old logic, but this will be replaced in a later change.
Add a '--sparse' flag in 'git pack-objects' to call this new logic.
Add a new test script t/t5322-pack-objects-sparse.sh that tests this
option. The tests currently demonstrate that the resulting object
list is the same as the old algorithm. This includes a case where
both algorithms pack an object that is not needed by a remote due to
limits on the explored set of trees. When the sparse algorithm is
changed in a later commit, we will add a test that demonstrates a
change of behavior in some cases.

Currently, a response to a fetch request has sideband support only while
the packfile is being sent, meaning that the server cannot send notices
until the start of the packfile.
Extend sideband support in protocol v2 fetch responses to the whole
response. upload-pack will advertise it if the
uploadpack.allowsidebandall configuration variable is set, and
fetch-pack will automatically request it if advertised.
If the sideband is to be used throughout the whole response, upload-pack
will use it to send errors instead of prefixing a PKT-LINE payload with
"ERR ".
This will be tested in a subsequent patch.

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.
