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.

The commit-graph feature is now on by default, and is being
written during 'git gc' by default. Typically, Git only writes
a commit-graph when a 'git gc --auto' command passes the gc.auto
setting to actualy do work. This means that a commit-graph will
typically fall behind the commits that are being used every day.
To stay updated with the latest commits, add a step to 'git
fetch' to write a commit-graph after fetching new objects. The
fetch.writeCommitGraph config setting enables writing a split
commit-graph, so on average the cost of writing this file is
very small. Occasionally, the commit-graph chain will collapse
to a single level, and this could be slow for very large repos.
For additional use, adjust the default to be true when
feature.experimental is enabled.

A common scenario is if a user is working on a topic branch and they
wish to make some changes to intermediate commits or autosquash, they
would run something such as
git rebase -i --onto master... master
in order to preserve the merge base. This is useful when contributing a
patch series to the Git mailing list, one often starts on top of the
current 'master'. While developing the patches, 'master' is also
developed further and it is sometimes not the best idea to keep rebasing
on top of 'master', but to keep the base commit as-is.
In addition to this, a user wishing to test individual commits in a
topic branch without changing anything may run
git rebase -x ./test.sh master... master
Since rebasing onto the merge base of the branch and the upstream is
such a common case, introduce the --keep-base option as a shortcut.
This allows us to rewrite the above as
git rebase -i --keep-base master
and
git rebase -x ./test.sh --keep-base master
respectively.
Add tests to ensure --keep-base works correctly in the normal case and
fails when there are multiple merge bases, both in regular and
interactive mode. Also, test to make sure conflicting options cause
rebase to fail. While we're adding test cases, add a missing
set_fake_editor call to 'rebase -i --onto master...side'.
While we're documenting the --keep-base option, change an instance of
"merge-base" to "merge base", which is the consistent spelling.

Before, when we rebased with a --fork-point invocation where the
fork-point wasn't empty, we would be setting options.restrict_revision.
The fast-forward logic would automatically declare that the rebase was
not fast-forwardable if it was set. However, this was painting with a
very broad brush.
Refine the logic so that we can fast-forward in the case where the
restricted revision is equal to the merge base, since we stop rebasing
at the merge base anyway.

Before, when we had the following graph,
A---B---C (master)
\
D (side)
running 'git rebase --onto master... master side' would result in D
being always rebased, no matter what. However, the desired behavior is
that rebase should notice that this is fast-forwardable and do that
instead.
Add detection to `can_fast_forward` so that this case can be detected
and a fast-forward will be performed. First of all, rewrite the function
to use gotos which simplifies the logic. Next, since the
options.upstream &&
!oidcmp(&options.upstream->object.oid, &options.onto->object.oid)
conditions were removed in `cmd_rebase`, we reintroduce a substitute in
`can_fast_forward`. In particular, checking the merge bases of
`upstream` and `head` fixes a failing case in t3416.
The abbreviated graph for t3416 is as follows:
F---G topic
/
A---B---C---D---E master
and the failing command was
git rebase --onto master...topic F topic
Before, Git would see that there was one merge base (C), and the merge
and onto were the same so it would incorrectly return 1, indicating that
we could fast-forward. This would cause the rebased graph to be 'ABCFG'
when we were expecting 'ABCG'.
With the additional logic, we detect that upstream and head's merge base
is F. Since onto isn't F, it means we're not rebasing the full set of
commits from master..topic. Since we're excluding some commits, a
fast-forward cannot be performed and so we correctly return 0.
Add '-f' to test cases that failed as a result of this change because
they were not expecting a fast-forward so that a rebase is forced.

The second case is when we are doing "git rebase --fork-point" and a

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

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

Add the --set-upstream option to git pull/fetch
which lets the user set the upstream configuration
(branch.<current-branch-name>.merge and
branch.<current-branch-name>.remote) for the current branch.
A typical use-case is:
git clone http://example.com/my-public-fork
git remote add main http://example.com/project-main-repo
git pull --set-upstream main master
or, instead of the last line:
git fetch --set-upstream main master
git merge # or git rebase
This is mostly equivalent to cloning project-main-repo (which sets
upsteam) and then "git remote add" my-public-fork, but may feel more
natural for people using a hosting system which allows forking from
the web UI.
This functionality is analog to "git push --set-upstream".

A pax extended header record starts with a decimal number. Its value
is the length of the whole record, including its own length.
The calculation of that number in strbuf_append_ext_header() is off by
one in case the length of the rest is close to a higher order of
magnitude. This affects paths and link targets a bit shorter than 1000,
10000, 100000 etc. characters -- paths with a length of up to 100 fit
into the tar header and don't need a pax extended header.
The mistake has been present since the function was added by ae64bbc18c
("tar-tree: Introduce write_entry()", 2006-03-25).
Account for digits added to len during the loop and keep incrementing

Completing configuration sections and variable names for the stuck
argument of 'git clone --config=<TAB>' requires a bit of extra care
compared to doing the same for the unstuck argument of 'git clone
--config <TAB>', because we have to deal with that '--config=' being
part of the current word to be completed.
Add an option to the __git_complete_config_variable_name_and_value()
and in turn to the __git_complete_config_variable_name() helper
functions to specify the current section/variable name to be
completed, so they can be used even when completing the stuck argument
of '--config='.
__git_complete_config_variable_value() already has such an option, and

The number of configuration variables listed by the completion script
grew quite when we started to auto-generate it from the documentation
[1], so we now complete them in two steps: first we list only the
section names, then the rest [2]. To get the section names we simply
strip everything following the first dot in each variable name,
resulting in a lot of repeated section names, because most sections
contain more than one configuration variable. This is not a
correctness issue in practice, because Bash's completion facilities
remove all repetitions anyway, but these repetitions make testing a
bit harder.
Replace the small 'sed' script removing subsections and variable names
with an 'awk' script that does the same, and in addition removes any
repeated configuration sections as well (by first creating and filling
an associative array indexed by all encountered configuration
sections, and then iterating over this array and printing the indices,
i.e. the unique section names). This change makes the failing 'git
config - section' test in 't9902-completion.sh' pass.
Note that this changes the order of section names in the output, and
makes it downright undeterministic, but this is not an issue, because
Bash sorts them before presenting them to the user, and our completion
tests sort them as well before comparing with the expected output.
Yeah, it would be simpler and shorter to just append '| sort -u' to
that command, but that would incur the overhead of one more external
process and pipeline stage every time a user completes configuration
sections.

The next patches will change/refactor the way we complete
configuration variable names and values, so add a few tests to cover
the basics, namely the completion of matching configuration sections,
full variable names, and their values.
Note that the test checking the completion of configuration sections
is currently failing, though it's not a sign of an actual bug. If a
section contains multiple variables, then that section is currently
repeated as many times as the number of variables in there. This is
not a correctness issue in practice, because Bash's completion
facilities remove all repetitions anyway. Consequently, we could list
all those repeated sections in the expected output of this test as
well, but then it would have to be updated whenever a new
configuration variable is added to those sections. Instead, list each
matching configuration section only once, mark the test as failing for
now, and the next patch will update the completion script to avoid
those repetitions.

mv: cannot stat '.git/objects//e84adb2704cbd49549e52169b4043871e13432': No such file or directory
The function generating that path:
test_oid_to_path () {
echo "${1%${1#??}}/${1#??}"
}
which is supposed to produce a result like
12/3456789....
But a dash bug[*] causes it to instead expand to
/3456789...
The stream of symbols that makes up this function is hard for humans
to follow, too. The complexity mostly comes from the repeated use of
the expression ${1#??} for the basename of the loose object. Use a
variable instead --- nowadays, the dialect of shell used by Git
permits local variables, so this is cheap.
An alternative way to work around [*] is to remove the double-quotes
around test_oid_to_path's return value. That makes the expression
easier for dash to read, but harder for humans. Let's prefer the
rephrasing that's helpful for humans, too.

The revision option parser recently learned about --end-of-options, but
that's not quite enough for all callers. Some of them, like git-log,
pick out some options using parse_options(), and then feed the remainder
to setup_revisions(). For those cases we need to stop parse_options()
from finding more options when it sees --end-of-options, and to retain
that option in argv so that setup_revisions() can see it as well.
Let's handle this the same as we do "--". We can even piggy-back on the
handling of PARSE_OPT_KEEP_DASHDASH, because any caller that wants to
retain one will want to retain the other.
I've included two tests here. The "log" test covers "--source", which is
one of the options it handles with parse_options(), and would fail
before this patch. There's also a test that uses the parse-options
helper directly. That confirms that the option is handled correctly even
in cases without KEEP_DASHDASH or setup_revisions(). I.e., it is safe to
use --end-of-options in place of "--" in other programs.

There's currently no robust way to tell Git that a particular option is
meant to be a revision, and not an option. So if you have a branch
"refs/heads/--foo", you cannot just say:
git rev-list --foo
You can say:
git rev-list refs/heads/--foo
But that breaks down if you don't know the refname, and in particular if
you're a script passing along a value from elsewhere. In most programs,
you can use "--" to end option parsing, like this:
some-prog -- "$revision"
But that doesn't work for the revision parser, because "--" is already
meaningful there: it separates revisions from pathspecs. So we need some
other marker to separate options from revisions.
This patch introduces "--end-of-options", which serves that purpose:
git rev-list --oneline --end-of-options "$revision"
will work regardless of what's in "$revision" (well, if you say "--" it
may fail, but it won't do something dangerous, like triggering an
unexpected option).
The name is verbose, but that's probably a good thing; this is meant to
be used for scripted invocations where readability is more important
than terseness.
One alternative would be to introduce an explicit option to mark a
revision, like:
git rev-list --oneline --revision="$revision"
That's slightly _more_ informative than this commit (because it makes
even something silly like "--" unambiguous). But the pattern of using a
separator like "--" is well established in git and in other commands,
and it makes some scripting tasks simpler like:
git rev-list --end-of-options "$@"
There's no documentation in this patch, because it will make sense to
describe the feature once it is available everywhere (and support will
be added in further patches).

Ever since commit 8c8e5bd6eb ("merge-recursive: switch directory
rename detection default", 2019-04-05), the default handling with
directory rename detection was to report a conflict and leave unstaged
entries in the index. However, when creating a virtual merge base in
the recursive case, we absolutely need a tree, and the only way a tree
can be written is if we have no unstaged entries -- otherwise we hit a
BUG().
There are a few fixes possible here which at least fix the BUG(), but
none of them seem optimal for other reasons; see the comments with the
new testcase 13e in t6043 for details (which testcase triggered a BUG()
prior to this patch). As such, just opt for a very conservative and
simple choice that is still relatively reasonable: have the recursive
case treat 'conflict' as 'false' for opt->detect_directory_renames.

In 1771be90 "commit-graph: merge commit-graph chains" (2019-06-18),
the method sort_and_scan_merged_commits() was added to merge the
commit lists of two commit-graph files in the incremental format.
Unfortunately, there was an off-by-one error in that method around
incrementing num_extra_edges, which leads to an incorrect offset
for the base graph chunk.
When we store an octopus merge in the commit-graph file, we store
the first parent in the normal place, but use the second parent
position to point into the "extra edges" chunk where the remaining
parents exist. This means we should be adding "num_parents - 1"
edges to this list, not "num_parents - 2". That is the basic error.
The reason this was not caught in the test suite is more subtle.
In 5324-split-commit-graph.sh, we test creating an octopus merge
and adding it to the tip of a commit-graph chain, then verify the
result. This _should_ have caught the problem, except that when
we load the commit-graph files we were overly careful to not fail
when the commit-graph chain does not match. This care was on
purpose to avoid race conditions as one process reads the chain
and another process modifies it. In such a case, the reading
process outputs the following message to stderr:
warning: commit-graph chain does not match
These warnings are output in the test suite, but ignored. By
checking the stderr of `git commit-graph verify` to include

Check that all input records are indeed valid commit object ids and
return with error otherwise, the same way '--stdin-packs' handles
invalid input; see e103f7276f (commit-graph: return with errors during
write, 2019-06-12).
Note that it should only return with error when encountering an
invalid commit object id coming from standard input. However,
'--reachable' uses the same code path to process object ids pointed to
by all refs, and that includes tag object ids as well, which should
still be skipped over. Therefore add a new flag to 'enum
commit_graph_write_flags' and a corresponding field to 'struct
write_commit_graph_context', so we can differentiate between those two
cases.

In 't5318-commit-graph.sh' the test 'close with correct error on bad
input' manually verifies the exit code of a 'git commit-graph write'
command.
Use 'test_expect_code' instead.

Hotfix for making "git log" use the mailmap by default.

log: really flip the --mailmap default
log: flip the --mailmap default unconditionally
The recently added [includeif "onbranch:branch"] feature does not
work well with an early config mechanism, as it attempts to find
out what branch we are on before we even haven't located the git
repository. The inclusion during early config scan is ignored to
work around this issue.
* js/early-config-with-onbranch:
config: work around bug with includeif:onbranch and early config
`git restore --staged` uses the same machinery as `git checkout HEAD`,
so there should be a similar test case for "restore" as the existing
test case for "checkout" with deleted ita files.

It is possible to delete a committed file from the index and then add it
as intent-to-add. After `git checkout HEAD <pathspec>`, the file should
be identical in the index and HEAD. The command already works correctly
if the file has contents in HEAD. This patch provides the desired
behavior even when the file is empty in HEAD.
`git checkout HEAD <pathspec>` calls tree.c:read_tree_1(), with fn
pointing to checkout.c:update_some(). update_some() creates a new cache
entry but discards it when its mode and oid match those of the old
entry. A cache entry for an ita file and a cache entry for an empty file
have the same oid. Therefore, an empty deleted ita file previously
passed both of these checks, and the new entry was discarded, so the
file remained unchanged in the index. After this fix, if the file is
marked as ita in the cache, then we avoid discarding the new entry and
add the new entry to the cache instead.
This change should not affect newly added ita files. For those, inside
tree.c:read_tree_1(), tree_entry_interesting() returns
entry_not_interesting, so fn is never called.

We have a couple of test scripts that are not completely
httpd-specific, but do run a few httpd-specific tests at the end.
These test scripts source 'lib-httpd.sh' somewhere mid-script, which
then skips all the rest of the test script if the dependencies for
running httpd tests are not fulfilled.
As the previous two patches in this series show, already on two
occasions non-httpd-specific tests were appended at the end of such
test scripts, and, consequently, they were skipped as well when httpd
tests couldn't be run.
Add a comment at the end of these test scripts to warn against adding
non-httpd-specific tests at the end, in the hope that they will help
prevent similar issues in the future.

't5703-upload-pack-ref-in-want.sh' sources 'lib-httpd.sh' near the end
to run a couple of httpd-specific tests, but 'lib-httpd.sh' skips all
the rest of the test script if the dependencies for running httpd
tests are not fulfilled. However, the last six tests in 't5703' are
not httpd-specific, but they are skipped as well when httpd tests
can't be run.
Move these six tests earlier in the test script, before 'lib-httpd.sh'
is sourced, so they will be run even when httpd tests aren't. Note
that this is not merely a pure code movement, because the setup test
case for the httpd tests needed an additional 'rm -rf
"$LOCAL_PRISTINE"' to clean up a directory left behind by the moved
non-httpd-specific tests.
Also add a comment at the end of this test script to warn against
adding non-httpd-specific tests at the end, in the hope that it will
help prevent similar issues in the future.

't5510-fetch.sh' sources 'lib-httpd.sh' near the end to run a
httpd-specific test, but 'lib-httpd.sh' skips all the rest of the test
script if the dependencies for running httpd tests are not fulfilled.
Alas, recently cdbd70c437 (fetch: add --[no-]show-forced-updates
argument, 2019-06-18) appended a non-httpd-specific test at the end,
and this test is then skipped as well when httpd tests can't be run.
Move this new test earlier in the test script, before 'lib-httpd.sh'
is sourced, so it will be run even when httpd tests aren't.
Also add a comment at the end of this test script to warn against
