When all of x/a, x/b, and x/c have moved to z/a, z/b, and z/c on one
branch, there is a question about whether x/d added on a different
branch should remain at x/d or appear at z/d when the two branches are
merged. There are different possible viewpoints here:
A) The file was placed at x/d; it's unrelated to the other files in
x/ so it doesn't matter that all the files from x/ moved to z/ on
one branch; x/d should still remain at x/d.
B) x/d is related to the other files in x/, and x/ was renamed to z/;
therefore x/d should be moved to z/d.
Since there was no ability to detect directory renames prior to
git-2.18, users experienced (A) regardless of context. Choice (B) was
implemented in git-2.18, with no option to go back to (A), and has been
in use since. However, one user reported that the merge results did not
match their expectations, making the change of default problematic,
especially since there was no notice printed when directory rename
detection moved files.
Note that there is also a third possibility here:
C) There are different answers depending on the context and content
that cannot be determined by git, so this is a conflict. Use a
higher stage in the index to record the conflict and notify the
user of the potential issue instead of silently selecting a
resolution for them.
Add an option for users to specify their preference for whether to use
directory rename detection, and default to (C). Even when directory
rename detection is on, add notice messages about files moved into new
directories.
As a sidenote, x/d did not have to be a new file here; it could have
already existed at some other path and been renamed to x/d, with
directory rename detection just renaming it again to z/d. Thus, it's
not just new files, but also a modification to all rename types (normal
renames, rename/add, rename/delete, rename/rename(1to1),
rename/rename(1to2), and rename/rename(2to1)).

When we switch from one branch to another, it makes sense to show a
summary of local changes since there could be conflicts, or some files
left modified.... When switch is used solely for creating a new
branch (and "switch" to the same commit) or detaching, we don't really
need to show anything.
"git checkout" does it anyway for historical reasons. But we can start
with a clean slate with switch and don't have to.
This essentially reverts fa655d8411 (checkout: optimize "git checkout
-b <new_branch>" - 2018-08-16) and make it default for switch,
but also for -B and --detach. Users of big repos are encouraged to

This is already the default in git-checkout. The real change in here is
just minor cleanup. The main excuse is to explain why dwim is kept default.
Contrary to detach mode that is easy to get into and confusing to get
back out. Automatically creating a tracking branch often does not kick
in as often (you would need a branch of the same name on a remote). And
since the branch creation is reported clearly, the user should be able
to undo/delete it if it's unwanted.

"git checkout" doing too many things is a source of confusion for many
users (and it even bites old timers sometimes). To remedy that, the
command will be split into two new ones: switch and restore. The good
old "git checkout" command is still here and will be until all (or most
of users) are sick of it.
See the new man page for the final design of switch. The actual
implementation though is still pretty much the same as "git checkout"
and not completely aligned with the man page. Following patches will
adjust their behavior to match the man page.

The description of --reset stays true to the first implementation in
438195cced (git-read-tree: add "--reset" flag, 2005-06-09). That is,
--reset discards unmerged entries. Or at least true to the commit
message because I can't be sure about read-tree's behavior regarding
local changes.
But in fcc387db9b (read-tree -m -u: do not overwrite or remove untracked
working tree files., 2006-05-17), it is clear that "-m -u" tries to keep
local changes, while --reset is singled out and will keep overwriting
worktree files. It's not stated in the commit message, but it's obvious
from the patch.
I went this far back not because I had a lot of free time, but because I
did not trust my reading of unpack-trees.c code. So far I think the
related changes in history agree with my understanding of the current
code, that "--reset" loses local changes.
This behavior is not mentioned in git-read-tree.txt, even though
old-timers probably can just guess it based on the "reset" name. Update
git-read-tree.txt about this.
Side note. There's another change regarding --reset that is not
obviously about local changes, b018ff6085 (unpack-trees: fix "read-tree
-u --reset A B" with conflicted index, 2012-12-29). But I'm pretty sure
this is about the first function of --reset, to discard unmerged entries
correctly.

When get-mark was introduced in commit 28c7b1f7b7 ("fast-import: add a

cat-blob command to be allowed on any line other than in the middle of a
data directive; see commit 777f80d742 ("fast-import: Allow cat-blob
requests at arbitrary points in stream", 2010-11-28). It was useful to
allow cat-blob directives in the middle of a commit to get more data
that would be used in writing the current commit object. get-mark is
not similarly useful since fast-import can already use either object id
or mark. Further, trying to allow this command anywhere caused parsing

In commit 777f80d742 ("fast-import: Allow cat-blob requests at
arbitrary points in stream", 2010-11-28), fast-import started allowing
cat-blob commands to appear on the start of any line except in the
middle of a "data" command. It could be in the middle of various
directives that were part of a tag command, or in the middle of
checkpoints or progresses (each of which allow an optional second empty
newline), or even immediately after the mark command of a blob before
the data directive appeared (raising the question of what if it used the
mark for the blob that just barely appeared in the stream that we do not
yet have the data for). None of these locations make any sense as
places to put cat-blob requests.
The purpose of this change as stated in that commit message was to
[save] frontends from having to loop over everything they want to
commit in the next commit and cat-ing the necessary objects in
advance.
However, that can be achieved by simply allowing cat-blob requests to
appear whenever a filemodify directive is allowed. Further, it avoids
setting a bad precedent for other commands to follow (e.g. get-mark); a
precedent which caused parsing problems in corner cases.
Technically, inline filemodify directives add a slight wrinkle in that
frontends might want to have cat-blob directives appear after the start
of the filemodify and before the data directive contained within it. I
think it would have been better to disallow such a case (it would be
trivial to use cat-blob before the filemodify instead), but since there
is evidence this was used, for backwards compatibility let's support
that case too.

works correctly (i.e. test_must_be_empty fails).

If you have staged changes in path A and perform 'checkout
--merge' (which could result in conflicts in a totally unrelated path
B), changes in A will be gone. Which is unexpected. We are supposed
to keep all changes, or kick and scream otherwise.
This is the result of how --merge is implemented, from the very first
day in 1be0659efc (checkout: merge local modifications while switching
branches., 2006-01-12):
1. a merge is done, unmerged entries are collected
2. a hard switch to a new branch is done, then unmerged entries added
back
There is no trivial fix for this. Going with 3-way merge one file at a
time loses rename detection. Going with 3-way merge by trees requires
teaching the algorithm to pick up staged changes. And even if we detect
staged changes with --merge and abort for safety, an option to continue
--merge is very weird. Such an option would keep worktree changes, but
drop staged changes.
Because the problem has been with us since the introduction of --merge
and everybody has been pretty happy (except Phillip, who found this
problem), I'll just take a note here to acknowledge it and wait for
merge wizards to come in and work their magic. There may be a way
forward [1].

Remove the rebase.useBuiltin setting, which was added as an escape
hatch to disable the builtin version of rebase first released with Git
2.20.
See [1] for the initial implementation of rebase.useBuiltin, and [2]
and [3] for the documentation and corresponding
GIT_TEST_REBASE_USE_BUILTIN option.
Carrying the legacy version is a maintenance burden as seen in
7e097e27d3 ("legacy-rebase: backport -C<n> and --whitespace=<option>
checks", 2018-11-20) and 9aea5e9286 ("rebase: fix regression in
rebase.useBuiltin=false test mode", 2019-02-13). Since the built-in
version has been shown to be stable enough let's remove the legacy
version.
As noted in [3] having use_builtin_rebase() shell out to get its
config doesn't make any sense anymore, that was done for the purposes
of spawning the legacy rebase without having modified any global
state. Let's instead handle this case in rebase_config().
There's still a bunch of references to git-legacy-rebase in po/*.po,
but those will be dealt with in time by the i18n effort.
Even though this configuration variable only existed two releases
let's not entirely delete the entry from the docs, but note its
absence. Individual versions of git tend to be around for a while due
to distro packaging timelines, so e.g. if we're "lucky" a given
version like 2.21 might be installed on say OSX for half a decade.
That'll mean some people probably setting this in config, and then
when they later wonder if it's needed they can Google search the
config option name or check it in git-config. It also allows us to
refer to the docs from the warning for details.

AsciiDoc and Asciidoctor do not agree on what to write in the header and
footer of each man-page, i.e., the very first and the very last line of
*.[157]. Those differences can certainly be interesting in their own
right, but they clutter the output of `./doc-diff --from-asciidoc
--to-asciidoctor HEAD HEAD` quite a bit since the diff contains some
10-15 lines of noise per file diffed.
Teach doc-diff to cut away the first two and last two lines, i.e., the
header/footer and the empty line immediately following/preceding it.
Because Asciidoctor uses an extra empty line compared to AsciiDoc,
remove one more line at each end of the file, but only if it's empty.
An alternative approach might be to pass down `--no-header-footer`,
which both AsciiDoc and Asciidoctor understand, but it has some
drawbacks. First of all, the result doesn't build -- `xmlto` stumbles on
the resulting xml since it has multiple root elements. Second, it cuts
too much -- dropping the header loses the synopsis, which would be
interesting to diff.
Like in the previous commit, encode this option into the directory name
of the "installed" and "rendered" files. Otherwise, we wouldn't be able

If you build the documentation switching between different options,

Enabling pack.writebitmaphashcache should always be a performance win.
It costs only 4 bytes per object on disk, and the timings in ae4f07fbcc
(pack-bitmap: implement optional name_hash cache, 2013-12-21) show it
improving fetch and partial-bitmap clone times by 40-50%.
The only reason we didn't enable it by default at the time is that early
versions of JGit's bitmap reader complained about the presence of
optional header bits it didn't understand. But that was changed in
JGit's d2fa3987a (Use bitcheck to check for presence of OPT_FULL option,
2013-10-30), which made it into JGit v3.5.0 in late 2014.
So let's turn this option on by default. It's backwards-compatible with
all versions of Git, and if you are also using JGit on the same
repository, you'd only run into problems using a version that's almost 5
years old.
We'll drop the manual setting from all of our test scripts, including
perf tests. This isn't strictly necessary, but it has two advantages:
1. If the hash-cache ever stops being enabled by default, our perf
regression tests will notice.
2. We can use the modified perf tests to show off the behavior of an
otherwise unconfigured repo, as shown below.
These are the results of a few of a perf tests against linux.git that
showed interesting results. You can see the expected speedup in 5310.4,
which was noted in ae4f07fbcc. Curiously, 5310.8 did not improve (and
actually got slower), despite seeing the opposite in ae4f07fbcc.
I don't have an explanation for that.
The tests from p5311 did not exist back then, but do show improvements
(a smaller pack due to better deltas, which we found in less time).

`OPT_ARGUMENT()` is intended to keep the specified long option in `argv`
and not to do anything else.
However, it would make a lot of sense for the caller to know whether
this option was seen at all or not. For example, we want to teach `git
difftool` to work outside of any Git worktree, but only when
`--no-index` was specified.
Note: nothing in Git uses OPT_ARGUMENT(). Even worse, looking through
the commit history, one can easily see that nothing even
ever used it, apart from the regression test.
So not only do we make `OPT_ARGUMENT()` more useful, we are also about
to introduce its first real user!

The current documentation uses both quotes (italics) and backquotes
(monospace) to render URLs and pathnames, which is inconsistent.
Document a best practice in CodingGuidelines to help reduce
inconsistencies in the future.
We set the best practice to using backquotes, since:
* It is already an established practice. For exemple:
$ git grep "'[^']/*[^']'" | wc -l
206
$ git grep '`[^`]/*[^`]`' | wc -l
690
There are false positives on both sides, but after a cursory look at
the output of both, it doesn't seem the false positive rate is really
higher in the second case.
At least, this shows that the existing documentation uses
inconsistent formatting, and that it would be good to do
something about it.
* It may be debatable whether path names need to be typed in
monospace but having them in italics is really unusual.

When we render, e.g., "linkgit:gitglossary[7]." with Asciidoctor, we get
"gitglossary(7) ." with a space between the linkgit macro expansion and
the punctuation. We can fix this by dropping the trailing newline after
we've turned `linkgit:foo[bar]` into `<citerefentry>..</citerefentry>`.
The diff produced by `USE_ASCIIDOCTOR=Yes ./doc-diff HEAD^ HEAD` is
almost 6000 lines large and shows how this fixes "git-foo(x) ,", "(see
git-bar(y) )" and so on. One might wonder whether this also turns, e.g.,
"see linkgit:foo[1] for more" into "see foo(1)for more", but no. We get
"...</citerefentry> for more" in the XML, see, e.g., git-am.xml, so the
space ends up in git-am.1 just fine. The same is true for the HTML output.

casting the net a bit too wide here, since we'll be rebuilding even with
AsciiDoc, which won't look at this file. But since this file changes so
rarely, that should be ok. It's better than missing a dependency.
Similarly, most of the html-files are produced directly from ".txt';

Rather than parse options manually, which is both difficult to
read and error prone, parse options supplied to commit-tree
using the parse-options api.
It was discovered that the --no-gpg-sign option was documented
but not implemented in commit 70ddbd7767 (commit-tree: add missing
--gpg-sign flag, 2019-01-19), and the existing implementation
would attempt to translate the option as a tree oid. It was also
suggested earlier in commit 55ca3f99ae (commit-tree: add and document
--no-gpg-sign, 2013-12-13) that commit-tree should be migrated to
utilize the parse-options api, which could help prevent mistakes
like this in the future. Hence this change.
Also update the documentation to better describe that mixing
`-m` and `-F` options will correctly compose commit log messages in the
order in which the options are given.
In the process, mark various strings for translation.

The --connectivity-only option avoids opening every object, and instead
just marks reachable objects with a flag and compares this to the set
of all objects. This strategy is discussed in more detail in 3e3f8bd608
(fsck: prepare dummy objects for --connectivity-check, 2017-01-17).
This means that we report _every_ unreachable object as dangling.
Whereas in a full fsck, we'd have actually opened and parsed each of
those unreachable objects, marking their child objects with the USED
flag, to mean "this was mentioned by another object". And thus we can
report only the tip of an unreachable segment of the object graph as
dangling.
You can see this difference with a trivial example:
tree=$(git hash-object -t tree -w /dev/null)
one=$(echo one | git commit-tree $tree)
two=$(echo two | git commit-tree -p $one $tree)
Running `git fsck` will report only $two as dangling, but with
--connectivity-only, both commits (and the tree) are reported. Likewise,
using --lost-found would write all three objects.
We can make --connectivity-only work like the normal case by taking a
separate pass over the unreachable objects, parsing them and marking
objects they refer to as USED. That still avoids parsing any blobs,
though we do pay the cost to access any unreachable commits and trees
(which may or may not be noticeable, depending on how many you have).
If neither --dangling nor --lost-found is in effect, then we can skip
this step entirely, just like we do now. That makes "--connectivity-only
--no-dangling" just as fast as the current "--connectivity-only". I.e.,
we do the correct thing always, but you can still tweak the options to
make it faster if you don't care about dangling objects.

On reading this again, there are two things that were not immediately
clear to me:
- we do still check links to blobs, even though we don't open the

open

The former wording implied that --no-commit would always cause the
merge operation to "pause" and allow the user to make further changes
and/or provide a special commit message for the merge commit. This
is not the case for fast-forward merges, as there is no merge commit
to create. Without a merge commit, there is no place where it makes
sense to "stop the merge and allow the user to tweak changes"; doing
that would require a full rebase of some sort.
Since users may be unaware of whether their branches have diverged or
not, modify the wording to correctly address fast-forward cases as well
and suggest using --no-ff with --no-commit if the point is to ensure
that the merge stops before completing.

The combined diff format for merges will only list one filename, even if
rename or copy detection is active. For example, with raw format one
might see:
::100644 100644 100644 fabadb8cc95eb04866510 MM describe.c
::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM bar.sh
::100644 100644 100644 e07d6c5 9042e82 ee91881 RR phooey.c
This doesn't let us know what the original name of bar.sh was in the
first parent, and doesn't let us know what either of the original names
of phooey.c were in either of the parents. In contrast, for non-merge
commits, raw format does provide original filenames (and a rename score
to boot). In order to also provide original filenames for merge
commits, add a --combined-all-paths option (which must be used with
either -c or --cc, and is likely only useful with rename or copy
detection active) so that we can print tab-separated filenames when
renames are involved. This transforms the above output to:
::100644 100644 100644 fabadb8cc95eb04866510 MM desc.c desc.c desc.c
::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM foo.sh bar.sh bar.sh
::100644 100644 100644 e07d6c5 9042e82 ee91881 RR fooey.c fuey.c phooey.c
Further, in patch format, this changes the from/to headers so that
instead of just having one "from" header, we get one for each parent.
For example, instead of having
--- a/phooey.c
+++ b/phooey.c
we would see
--- a/fooey.c
--- a/fuey.c
+++ b/phooey.c

This patch was contributed only as a tentative "we could introduce a
convenient short option if we do not want to change the default behavior
in the long run" patch, opening the discussion whether other people
agree with deprecating the current behavior in favor of the rescheduling
behavior.
But the consensus on the Git mailing list was that it would make sense
to show a warning in the near future, and flip the default
rebase.rescheduleFailedExec to reschedule failed `exec` commands by
default. See e.g.
<CAGZ79kZL5CRqCDRb6B-EedUm8Z_i4JuSF2=UtwwdRXMitrrOBw@mail.gmail.com>
So let's back out that patch that added the `-y` short option that we
agreed was not necessary or desirable.
This reverts commit 81ef8ee75d.

This reverts 1495ff7da5 ("checkout: introduce checkout.overlayMode

option.
The option was originally introduced to give users the option to make
the new no-overlay behaviour the default. However users may be using
'git checkout' in scripts, even though it is porcelain. Users setting
the option to false may actually end up accidentally breaking scripts.
With the introduction of a new subcommand that will make the behaviour
the default, the config option will not be needed anymore anyway.
Revert the commit and remove the config option, so we don't risk
breaking scripts.

`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 author.email, author.name, committer.email and committer.name
settings are analogous to the GIT_AUTHOR_* and GIT_COMMITTER_*
environment variables, but for the git config system. This allows them
to be set separately for each repository.
Git supports setting different authorship and committer
information with environment variables. However, environment variables
are set in the shell, so if different authorship and committer
information is needed for different repositories an external tool is
required.
This adds support to git config for author.email, author.name,
committer.email and committer.name settings so this information
can be set per repository.
Also, it generalizes the fmt_ident function so it can handle author vs
committer identification.

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)

With this patch it is possible to launch git-instaweb by using

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.

While the format is more useful to humans by dropping inferred

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

calls.

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.

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.

Currently 'git checkout' is defined as an overlay operation, which
means that if in 'git checkout <tree-ish> -- [<pathspec>]' we have an
entry in the index that matches <pathspec>, but that doesn't exist in
<tree-ish>, that entry will not be removed from the index or the
working tree.
Introduce a new --{,no-}overlay option, which allows using 'git
checkout' in non-overlay mode, thus removing files from the working
tree if they do not exist in <tree-ish> but match <pathspec>.
Note that 'git checkout -p <tree-ish> -- [<pathspec>]' already works
this way, so no changes are needed for the patch mode. We disallow
'git checkout --overlay -p' to avoid confusing users who would expect
to be able to force overlay mode in 'git checkout -p' this way.
Untracked files are not affected by this change, so 'git checkout
--no-overlay HEAD -- untracked' will not remove untracked from the
working tree. This is so e.g. 'git checkout --no-overlay HEAD -- dir/'
doesn't delete all untracked files in dir/, but rather just resets the
state of files that are known to git.

As part of an ongoing effort to make rebase have more uniform behavior,
modify the merge backend to behave like the interactive one, by
re-implementing it on top of the latter.
Interactive rebases are implemented in terms of cherry-pick rather than
the merge-recursive builtin, but cherry-pick also calls into the
recursive merge machinery by default and can accept special merge
strategies and/or special strategy options. As such, there really is
not any need for having both git-rebase--merge and
git-rebase--interactive anymore. Delete git-rebase--merge.sh and
instead implement it in builtin/rebase.c.
This results in a few deliberate but small user-visible changes:
* The progress output is modified (see t3406 and t3420 for examples)
* A few known test failures are now fixed (see t3421)
* bash-prompt during a rebase --merge is now REBASE-i instead of
REBASE-m. Reason: The prompt is a reflection of the backend in use;
this allows users to report an issue to the git mailing list with
the appropriate backend information, and allows advanced users to
know where to search for relevant control files. (see t9903)
testcase modification notes:
t3406: --interactive and --merge had slightly different progress output
while running; adjust a test to match the new expectation
t3420: these test precise output while running, but rebase--am,
rebase--merge, and rebase--interactive all were built on very
different commands (am, merge-recursive, cherry-pick), so the
tests expected different output for each type. Now we expect
--merge and --interactive to have the same output.
t3421: --interactive fixes some bugs in --merge! Wahoo!
t9903: --merge uses the interactive backend so the prompt expected is
now REBASE-i.

In the Git pack protocol definition, an error packet may appear only in
a certain context. However, servers can face a runtime error (e.g. I/O
error) at an arbitrary timing. This patch changes the protocol to allow
an error packet to be sent instead of any packet.
Without this protocol spec change, when a server cannot process a
request, there's no way to tell that to a client. Since the server
cannot produce a valid response, it would be forced to cut a connection
without telling why. With this protocol spec change, the server can be
more gentle in this situation. An old client may see these error packets
as an unexpected packet, but this is not worse than having an unexpected
EOF.
Following this protocol spec change, the error packet handling code is
moved to pkt-line.c. Implementation wise, this implementation uses
pkt-line to communicate with a subprocess. Since this is not a part of
Git protocol, it's possible that a packet that is not supposed to be an
error packet is mistakenly parsed as an error packet. This error packet
handling is enabled only for the Git pack protocol parsing code
considering this.

Asciidoctor removes the indentation of each line in these tables, so the
last lines of each table have a completely broken alignment.
Similar to 379805051d ("Documentation: render revisions correctly under
Asciidoctor", 2018-05-06), use an explicit literal block to indicate
that we want to keep the leading whitespace in the tables.
Because this gives us some extra indentation, we can remove the one that
we have been carrying explicitly. That is, drop the first four spaces of
indentation on each line. With Asciidoc (8.6.10), this results in
identical rendering before and after this commit, both for git-status.1

The -G<regex> option of log looks for the differences whose patch text
contains added/removed lines that match regex.
Currently -G looks also into patches of binary files (which
according to [1]) is binary as well.
This has a couple of issues:
- It makes the pickaxe search slow. In a proprietary repository of the
author with only ~5500 commits and a total .git size of ~300MB
searching takes ~13 seconds
$time git log -Gwave > /dev/null
real 0m13,241s
user 0m12,596s
sys 0m0,644s
whereas when we ignore binary files with this patch it takes ~4s
$time ~/devel/git/git log -Gwave > /dev/null
real 0m3,713s
user 0m3,608s
sys 0m0,105s
which is a speedup of more than fourfold.
- The internally used algorithm for generating patch text is based on
xdiff and its states in [1]
> The output format of the binary patch file is proprietary
> (and binary) and it is basically a collection of copy and insert
> commands [..]
which means that the current format could change once the internal
algorithm is changed as the format is not standardized. In addition
the git binary patch format used for preparing patches for git apply
is *different* from the xdiff format as can be seen by comparing

However, when an `exec` in such a rebase fails, it is not re-scheduled,

If a user explicitly sets
[index]
threads = true
to read the index using multiple threads, ensure that index writes
include the offset table by default to make that possible. This
ensures that the user's intent of turning on threading is respected.
In other words, permit the following configurations:
- index.threads and index.recordOffsetTable unspecified: do not write
the offset table yet (to avoid alarming the user with "ignoring IEOT
extension" messages when an older version of Git accesses the
repository) but do make use of multiple threads to read the index if
the supporting offset table is present.
This can also be requested explicitly by setting index.threads=true,
0, or >1 and index.recordOffsetTable=false.
- index.threads=false or 1: do not write the offset table, and do not
make use of the offset table.
One can set index.recordOffsetTable=false as well, to be more
explicit.
- index.threads=true, 0, or >1 and index.recordOffsetTable unspecified:
write the offset table and make use of threads at read time.
This can also be requested by setting index.threads=true, 0, >1, or
unspecified and index.recordOffsetTable=true.
Fortunately the complication is temporary: once most Git installations
have upgraded to a version with support for the IEOT and EOIE
extensions, we can flip the defaults for index.recordEndOfIndexEntries
and index.recordOffsetTable to true and eliminate the settings.

versions of Git, it produces a confusing warning:

of optimization to take a shortcut when things don't match.
Note that if :(attr) is present, we can't return
all_entries_interesting / all_entries_not_interesting anymore because
we can't be certain about that. Not until match_pathspec_attrs() can
tell us "yes all these paths satisfy :(attr)".
Second note. Even though we walk a specific tree, we use attributes

Knowing the original names (hashes) of commits can sometimes enable
post-filtering that would otherwise be difficult or impossible. In
particular, the desire to rewrite commit messages which refer to other
prior commits (on top of whatever other filtering is being done) is
very difficult without knowing the original names of each commit.
In addition, knowing the original names (hashes) of blobs can allow
filtering by blob-id without requiring re-hashing the content of the
blob, and is thus useful as a small optimization.
Once we add original ids for both commits and blobs, we may as well
add them for tags too for completeness. Perhaps someone will have a
use for them.
This commit teaches a new --show-original-ids option to fast-export
which will make it add a 'original-oid <hash>' line to blob, commits,
and tags. It also teaches fast-import to parse (and ignore) such

git filter-branch has a nifty feature allowing you to rewrite, e.g. just
the last 8 commits of a linear history
git filter-branch $OPTIONS HEAD~8..HEAD
If you try the same with git fast-export, you instead get a history of
only 8 commits, with HEAD~7 being rewritten into a root commit. There
are two alternatives:
1) Don't use the negative revision specification, and when you're
filtering the output to make modifications to the last 8 commits,
just be careful to not modify any earlier commits somehow.
2) First run 'git fast-export --export-marks=somefile HEAD~8', then
run 'git fast-export --import-marks=somefile HEAD~8..HEAD'.
Both are more error prone than I'd like (the first for obvious reasons;
with the second option I have sometimes accidentally included too many
revisions in the first command and then found that the corresponding
extra revisions were not exported by the second command and thus were
not modified as I expected). Also, both are poor from a performance
perspective.
Add a new --reference-excluded-parents option which will cause
fast-export to refer to commits outside the specified rev-list-args
range by their sha1sum. Such a stream will only be useful in a
repository which already contains the necessary commits (much like the
restriction imposed when using --no-data).
Note from Peff:
I think we might be able to do a little more optimization here. If
we're exporting HEAD^..HEAD and there's an object in HEAD^ which is
unchanged in HEAD, I think we'd still print it (because it would not
be marked SHOWN), but we could omit it (by walking the tree of the
boundary commits and marking them shown). I don't think it's a
blocker for what you're doing here, but just a possible future
optimization.

The rebase.useBuiltin variable introduced in 55071ea248 ("rebase:
start implementing it as a builtin", 2018-08-07) was turned on by
default in 5541bd5b8f ("rebase: default to using the builtin rebase",
2018-08-08), but had no documentation.
Let's document it so that users who run into any stability issues with
the C rewrite know there's an escape hatch[1], and make it clear that
needing to turn off builtin rebase means you've found a bug in git.

All config extensions are described in technical/repository-version.txt.
I made a mistake of adding it in config.txt instead. This patch moves
it back to where it belongs.
Since repository-version.txt is not part of officially generated
documents (it's not even part of DOC_HTML target), it's only visible
to developers who read plain .txt files. Let's include it in
gitrepository-layout.5 for more visibility. Some minor asciidoc fixes
are required in repository-version.txt to make this happen.

Due to limitations in the current implementation, some configuration

clone') are ignored during the initial fetch and checkout.
Let the users know which configuration variables are known to be

'--mirror' and '--no-tags' instead.

Document the DWYM behavior that kicks in when pushing to an
unqualified <dst> reference.
This behavior was added in f88395ac23 ("Renaming push.", 2005-08-03)
and f8aae12034 ("push: allow unqualified dest refspecs to DWIM",
2008-04-23), and somewhat documented in bb9fca80ce ("git-push: Update
description of refspecs and add examples", 2007-06-09), but has never
been fully documented.
The closest we got to having documented it was the description in the
commit message for f8aae12034, which I've borrowed from in writing
this documentation.
Let's also refer to this new documentation from the existing
documentation we had (added in bb9fca80ce).

Add an advice to the recently improved error message added in
f8aae12034 ("push: allow unqualified dest refspecs to DWIM",
2008-04-23).
Now with advice.pushUnqualifiedRefName=true (on by default) we show a
hint about how to proceed:
$ ./git-push avar v2.19.0^{commit}:newbranch -n
error: The destination you provided is not a full refname (i.e.,
starting with "refs/"). We tried to guess what you meant by:
- Looking for a ref that matches 'newbranch' on the remote side.
- Checking if the <src> being pushed ('v2.19.0^{commit}')
is a ref in "refs/{heads,tags}/". If so we add a corresponding
refs/{heads,tags}/ prefix on the remote side.
Neither worked, so we gave up. You must fully qualify the ref.
hint: The <src> part of the refspec is a commit object.
hint: Did you mean to create a new branch by pushing to
hint: 'v2.19.0^{commit}:refs/heads/newbranch'?
error: failed to push some refs to 'git@github.com:avar/git.git'
When trying to push a tag, tree or a blob we suggest that perhaps the
user meant to push them to refs/tags/ instead.
The if/else duplication for all of OBJ_{COMMIT,TAG,TREE,BLOB} is
unfortunate, but is required to correctly mark the messages for
translation. See the discussion in
<87r2gxebsi.fsf@evledraar.gmail.com> about that.

When checkout dwim is added in [1], it is restricted to only dwim when
certain conditions are met and fall back to default checkout behavior
otherwise. It turns out falling back could be confusing. One of the
conditions to turn
git checkout frotz
to
git checkout -b frotz origin/frotz
is that frotz must not exist as a file. But when the user comes to
expect "git checkout frotz" to create the branch "frotz" and there
happens to be a file named "frotz", git's silently reverting "frotz"
file content is not helping. This is reported in Git mailing list [2]
and even used as an example of "Git is bad" elsewhere [3].
We normally try to do the right thing, but when there are multiple
"right things" to do, it's best to leave it to the user to decide.
Check this case, ask the user to to disambiguate:
- "git checkout -- foo" will check out path "foo"
- "git checkout foo --" will dwim and create branch "foo" [4]
For users who do not want dwim, use --no-guess. It's useless in this
particular case because "git checkout --no-guess foo --" will just
fail. But it could be used by scripts.

The code to traverse objects for reachability, used to decide what
objects are unreferenced and expendable, have been taught to also
consider per-worktree refs of other worktrees as starting points to
prevent data loss.
* nd/per-worktree-ref-iteration:
git-worktree.txt: correct linkgit command name
reflog expire: cover reflog from all worktrees
fsck: check HEAD and reflog from other worktrees
fsck: move fsck_head_link() to get_default_heads() to avoid some globals
revision.c: better error reporting on ref from different worktrees
revision.c: correct a parameter name
refs: new ref types to make per-worktree refs visible to all worktrees
Add a place for (not) sharing stuff between worktrees
refs.c: indent with tabs, not spaces
A pattern with '**' that does not have a slash on either side used
to be an invalid one, but the code now treats such double-asterisks
the same way as two normal asterisks that happen to be adjacent to
each other.

wildmatch: change behavior of "foo**bar" in WM_PATHNAME mode
A fourth class of configuration files (in addition to the
traditional "system wide", "per user in the $HOME directory" and
"per repository in the $GIT_DIR/config") has been introduced so
that different worktrees that share the same repository (hence the
same $GIT_DIR/config file) can use different customization.
* nd/per-worktree-config:
worktree: add per-worktree config files
t1300: extract and use test_cmp_config()
Split the overly large Documentation/config.txt file into million
little pieces. This potentially allows each individual piece
included into the manual page of the command it affects more easily.

But different versions of libcurl, the default value is not the same.
CURL >= 7.62.0: CURL_HTTP_VERSION_2TLS
CURL < 7.62: CURL_HTTP_VERSION_1_1
In order to give users the freedom to control the HTTP version,

Operations on promisor objects make sense in the context of only a
small subset of the commands that internally use the revisions

There are no users of OPT_DATE except for test-parse-options; its
only caller went away in 27ec394a97 (prune: introduce OPT_EXPIRY_DATE()
and use it, 2013-04-25).
It also has a bug: it does not specify PARSE_OPT_NONEG, but its callback
does not respect the "unset" flag, and will feed NULL to approxidate()
and segfault. Probably this should be marked with NONEG, or the callback
should set the timestamp to some sentinel value (e.g,. "0", or
"(time_t)-1").
But since there are no callers, deleting it means we don't even have to
think about what the right behavior should be.

In WM_PATHNAME mode (or FNM_PATHNAME), '*' does not match '/' and '**'
can but only in three patterns:
- '**/' matches zero or more leading directories
- '/**/' matches zero or more directories in between
- '/**' matches zero or more trailing directories/files
When '**' is present but not in one of these patterns, the current
behavior is consider the pattern invalid and stop matching. In other
words, 'foo**bar' never matches anything, whatever you throw at it.
This behavior is arguably a bit confusing partly because we can't
really tell the user their pattern is invalid so that they can fix
it. So instead, tolerate it and make '**' act like two regular '*'s
(which is essentially the same as a single asterisk). This behavior
seems more predictable.
