rewrote the code for setting the committer date to use fmt_ident(),
rather than setting an environment variable and letting commit_tree()
handle it. But it introduced two bugs:
- we use the author email string instead of the committer email
- when parsing the committer ident, we used the wrong variable to
compute the length of the email, resulting in it always being a

sideband: report unhandled incomplete sideband messages as bugs
It was pretty tricky to verify that incomplete sideband messages are
handled correctly by the `recv_sideband()`/`demultiplex_sideband()`
code: they have to be flushed out at the end of the loop in
`recv_sideband()`, but the actual flushing is done by the
`demultiplex_sideband()` function (which therefore has to know somehow
that the loop will be done after it returns).
To catch future bugs where incomplete sideband messages might not be
shown by mistake, let's catch that condition and report a bug.

sideband: avoid reporting incomplete sideband messages
In
2b695ecd74d (t5500: count objects through stderr, not trace,
2020-05-06) we tried to ensure that the "Total 3" message could be
grepped in Git's output, even if it sometimes got chopped up into
multiple lines in the trace machinery.
However, the first instance where this mattered now goes through the
sideband machinery, where it is _still_ possible for messages to get
chopped up: it *is* possible for the standard error stream to be sent
byte-for-byte and hence it can be easily interrupted. Meaning: it is
possible for the single line that we're looking for to be chopped up
into multiple sideband packets, with a primary packet being delivered
between them.
This seems to happen occasionally in the `vs-test` part of our CI
builds, i.e. with binaries built using Visual C, but not when building
with GCC or clang; The symptom is that t5500.43 fails to find a line
matching `remote: Total 3` in the `log` file, which ends in something
along these lines:
remote: Tota
remote: l 3 (delta 0), reused 0 (delta 0), pack-reused 0
This should not happen, though: we have code in `demultiplex_sideband()`
_specifically_ to stitch back together lines that were delivered in
separate sideband packets.
However, this stitching was broken in a subtle way in
fbd76cd450
(sideband: reverse its dependency on pkt-line, 2019-01-16): before that
change, incomplete sideband lines would not be flushed upon receiving a
primary packet, but after that patch, they would be.
The subtleness of this bug comes from the fact that it is easy to get
confused by the ambiguous meaning of the `break` keyword: after writing
the primary packet contents, the `break;` in the original version of
`recv_sideband()` does _not_ break out of the `while` loop, but instead
only ends the `switch` case:
while (!retval) {
[...]
switch (band) {
[...]
case 1:
/* Write the contents of the primary packet */
write_or_die(out, buf + 1, len);
/* Here, we do *not* break out of the loop, `retval` is unchanged */
break;
[...]
}
if (outbuf.len) {
/* Write any remaining sideband messages lacking a trailing LF */
strbuf_addch(&outbuf, '\n');
xwrite(2, outbuf.buf, outbuf.len);
}
In contrast, after
fbd76cd450 (sideband: reverse its dependency on
pkt-line, 2019-01-16), the body of the `while` loop was extracted into
`demultiplex_sideband()`, crucially _including_ the logic to write
incomplete sideband messages:
switch (band) {
[...]
case 1:
*sideband_type = SIDEBAND_PRIMARY;
/* This does not break out of the loop: the loop is in the caller */
break;
[...]
}
cleanup:
[...]
/* This logic is now no longer _outside_ the loop but _inside_ */
if (scratch->len) {
strbuf_addch(scratch, '\n');
xwrite(2, scratch->buf, scratch->len);
}
The correct way to fix this is to return from `demultiplex_sideband()`
early. The caller will then write out the contents of the primary packet
and continue looping. The `scratch` buffer for incomplete sideband
messages is owned by that caller, and will continue to accumulate the
remainder(s) of those messages. The loop will only end once
`demultiplex_sideband()` returned non-zero _and_ did not indicate a
primary packet, which is the case only when we hit the `cleanup:` path,
in which we take care of flushing any unfinished sideband messages and
release the `scratch` buffer.
To ensure that this does not get broken again, we introduce a pair of
subcommands of the `pkt-line` test helper that specifically chop up the
sideband message and squeeze a primary packet into the middle.
Final note: The other test case touched by
2b695ecd74d (t5500: count
objects through stderr, not trace, 2020-05-06) is not affected by this
issue because the sideband machinery is not involved there.

Documentation: stylistically normalize references to Signed-off-by:
Ted reported an old typo in the git-commit.txt and merge-options.txt.
Namely, the phrase "Signed-off-by line" was used without either a
definite nor indefinite article.
Upon examination, it seems that the documentation (including items in
Documentation/, but also option help strings) have been quite
inconsistent on usage when referring to `Signed-off-by`.
First, very few places used a definite or indefinite article with the
phrase "Signed-off-by line", but that was the initial typo that led
to this investigation. So, normalize using either an indefinite or
definite article consistently.
The original phrasing, in Commit
3f971fc425b (Documentation updates,
2005-08-14), is "Add Signed-off-by line". Commit
6f855371a53 (Add
--signoff, --check, and long option-names. 2005-12-09) switched to
using "Add `Signed-off-by:` line", but didn't normalize the former
commit to match. Later commits seem to have cut and pasted from one
or the other, which is likely how the usage became so inconsistent.
Junio stated on the git mailing list in
<xmqqy2k1dfoh.fsf@gitster.c.googlers.com> a preference to leave off
the colon. Thus, prefer `Signed-off-by` (with backticks) for the
documentation files and Signed-off-by (without backticks) for option
help strings.
Additionally, Junio argued that "trailer" is now the standard term to
refer to `Signed-off-by`, saying that "becomes plenty clear that we
are not talking about any random line in the log message". As such,
prefer "trailer" over "line" anywhere the former word fits.
However, leave alone those few places in documentation that use
Signed-off-by to refer to the process (rather than the specific
trailer), or in places where mail headers are generally discussed in
comparison with Signed-off-by.

SubmittingPatches: clarify DCO is our --signoff rule
The description on sign-off and DCO was written back in the days
where there was only a choice between "use sign-off and it means the
contributor agrees to the Linux-kernel style DCO" and "not using
sign-off at all will make your patch unusable". These days, we are
trying to clarify that the exact meaning of a sign-off varies
project to project.
Let's be more explicit when presenting what _our_ rules are. It is
of secondary importance that it originally came from the kernel
project, so move the description as a historical note at the end,
while cautioning that what a sign-off means to us may be different from
what it means to other projects contributors may have been used to.

that any project using Git may and often does set its own policy.
However, leave intact reference to the Linux DCO, which Git also
uses. It is reasonable for Git to advocate for its own Signed-off-by

remains respectful that YMMV and other projects may well have very
different contributor representations tied to Signed-off-by.

doc: preparatory clean-up of description on the sign-off option
Almost identical text on the signed-off-by trailer appears in the
documentation for "git commit" and "git merge" and its friends.
Introduce a new signoff-option.txt file to be shared. A couple of
things of note are:
- The short-form "-s" is available only in "git commit", but not in
commands that are friends of "git merge", as it is used as a
short-hand for "--strategy".
- The original lacks description on the negated "--no-signoff" form
on "git commit" side, but it equally is applicable. It however
was unclear in the original text that not adding a Signed-off-by
trailer is the default, so rephrase to explain it as a way to
countermand a --signoff option that appeared earlier on the same
command line.
This is in preparation to apply a further clarification on what
exactly the Signed-off-by trailer means.

fast-import: fix over-allocation of marks storage
Fast-import stores its marks in a trie-like structure made of mark_set
structs. Each struct has a fixed size (1024). If our id number is too
large to fit in the struct, then we allocate a new struct which shifts
the id number by 10 bits. Our original struct becomes a child node
of this new layer, and the new struct becomes the top level of the trie.
This scheme was broken by
ddddf8d7e2 (fast-import: permit reading
multiple marks files, 2020-02-22). Before then, we had a top-level
"marks" pointer, and the push-down worked by assigning the new top-level
struct to "marks". But after that commit, insert_mark() takes a pointer
to the mark_set, rather than using the global "marks". It continued to
assign to the global "marks" variable during the push down, which was
wrong for two reasons:
- we added a call in option_rewrite_submodules() which uses a separate
mark set; pushing down on "marks" is outright wrong here. We'd
corrupt the "marks" set, and we'd fail to correctly store any
submodule mappings with an id over 1024.
- the other callers passed "marks", but the push-down was still wrong.
In read_mark_file(), we take the pointer to the mark_set as a
parameter. So even though insert_mark() was updating the global
"marks", the local pointer we had in read_mark_file() was not
updated. As a result, we'd add a new level when needed, but then the
next call to insert_mark() wouldn't see it! It would then allocate a
new layer, which would also not be seen, and so on. Lookups for the
lost layers obviously wouldn't work, but before we even hit any
lookup stage, we'd generally run out of memory and die.
Our tests didn't notice either of these cases because they didn't have
enough marks to trigger the push-down behavior. The new tests in t9304
cover both cases (and fail without this patch).
We can solve the problem by having insert_mark() take a pointer-to-pointer
of the top-level of the set. Then our push down can assign to it in a
way that the caller actually sees. Note the subtle reordering in
option_rewrite_submodules(). Our call to read_mark_file() may modify our
top-level set pointer, so we have to wait until after it returns to
assign its value into the string_list.

commit-graph: don't write commit-graph when disabled
The core.commitGraph config setting can be set to 'false' to prevent
parsing commits from the commit-graph file(s). This causes an issue when
trying to write with "--split" which needs to distinguish between
commits that are in the existing commit-graph layers and commits that
are not. The existing mechanism uses parse_commit() and follows by
checking if there is a 'graph_pos' that shows the commit was parsed from
the commit-graph file.
When core.commitGraph=false, we do not parse the commits from the
commit-graph and 'graph_pos' indicates that no commits are in the
existing file. The --split logic moves forward creating a new layer on
top that holds all reachable commits, then possibly merges down into
those layers, resulting in duplicate commits. The previous change makes
that merging process more robust to such a situation in case it happens
in the written commit-graph data.
The easy answer here is to avoid writing a commit-graph if reading the
commit-graph is disabled. Since the resulting commit-graph will would not
be read by subsequent Git processes. This is more natural than forcing
core.commitGraph to be true for the 'write' process.

commit-graph: ignore duplicates when merging layers
Thomas reported [1] that a "git fetch" command was failing with an error
saying "unexpected duplicate commit id". The root cause is that they had
fetch.writeCommitGraph enabled which generates commit-graph chains, and
this instance was merging two layers that both contained the same commit
ID.
[1] https://lore.kernel.org/git/
55f8f00c-a61c-67d4-889e-
a9501c596c39@virtuell-zuhause.de/
The initial assumption is that Git would not write a commit ID into a
commit-graph layer if it already exists in a lower commit-graph layer.
Somehow, this specific case did get into that situation, leading to this
error.
While unexpected, this isn't actually invalid (as long as the two layers
agree on the metadata for the commit). When we parse a commit that does
not have a graph_pos in the commit_graph_data_slab, we use binary search
in the commit-graph layers to find the commit and set graph_pos. That
position is never used again in this case. However, when we parse a
commit from the commit-graph file, we load its parents from the
commit-graph and assign graph_pos at that point. If those parents were
already parsed from the commit-graph, then nothing needs to be done.
Otherwise, this graph_pos is a valid position in the commit-graph so we
can parse the parents, when necessary.
Thus, this die() is too aggressive. The easiest thing to do would be to
ignore the duplicates.
If we only ignore the duplicates, then we will produce a commit-graph
that has identical commit IDs listed in adjacent positions. This excess
data will never be removed from the commit-graph, which could cascade
into significantly bloated file sizes.
Thankfully, we can collapse the list to erase the duplicate commit
pointers. This allows us to get the end result we want without extra
memory costs and minimal CPU time.
The root cause is due to disabling core.commitGraph, which prevents
parsing commits from the lower layers during a 'git commit-graph write
--split' command. Since we use the 'graph_pos' value to determine
whether a commit is in a lower layer, we never discover that those
commits are already in the commit-graph chain and add them to the top
layer. This layer is then merged down, creating duplicates.
The test added in t5324-split-commit-graph.sh fails without this change.
However, we still have not completely removed the need for this
duplicate check. That will come in a follow-up change.

ci: github action - add check for whitespace errors
Not all developers are aware of `git diff --check` to warn
about whitespace issues. Running a check when a pull request is
opened or updated can save time for reviewers and the submitter.
A GitHub workflow will run when a pull request is created or the
contents are updated to check the patch series. A pull request
provides the necessary information (number of commits) to only
check the patch series.
To ensure the developer is aware of any issues, a comment will be
added to the pull request with the check errors.
