"git pull" with any strategy when the other side is behind us
should succeed as it is a no-op, but doesn't.
* ev/pull-already-up-to-date-is-noop:
pull: should be noop when already-up-to-date

The already-up-to-date pull bug was fixed for --ff-only but it did not
include the case where --ff or --ff-only are not specified. This updates
the --ff-only fix to include the case where --ff or --ff-only are not
specified in command line flags or config.

"git pull --ff-only" and "git pull --rebase --ff-only" should make
it a no-op to attempt pulling from a remote that is behind us, but
instead the command errored out by saying it was impossible to
fast-forward, which may technically be true, but not a useful thing
to diagnose as an error. This has been corrected.

"git pull --no-verify" did not affect the underlying "git merge".

pull: honor --no-verify and do not call the commit-msg hook

Earlier, we made sure that "git pull --ff-only" (and "git -c
pull.ff=only pull") errors out when our current HEAD is not an
ancestor of the tip of the history we are merging, but the condition
to trigger the error was implemented incorrectly.
Imagine you forked from a remote branch, built your history on top
of it, and then attempted to pull from them again. If they have not
made any update in the meantime, our current HEAD is obviously not
their ancestor, and this new error triggers.
Without the --ff-only option, we just report that there is no need
to pull; we did the same historically with --ff-only, too.
Make sure we do not fail with the recently added check to restore
the historical behaviour.

The option was incorrectly auto-translated to "--no-verify-signatures",
which causes the unexpected effect of the hook being called.
And an even more unexpected effect of disabling verification of signatures.
The manual page describes the option to behave same as the similarly
named option of "git merge", which seems to be the original intention
of this option in the "pull" command.

The run-command API has been updated so that the callers can easily
ask the file descriptors open for packfiles to be closed immediately
before spawning commands that may trigger auto-gc.
* js/run-command-close-packs:
Close object store closer to spawning child processes
run_auto_maintenance(): implicitly close the object store
run-command: offer to close the object store before running
run-command: prettify the `RUN_COMMAND_*` flags
pull: release packs before fetching
commit-graph: when closing the graph, also release the slab
|
|
In many cases where we spawned child processes that _may_ trigger a
repack, we explicitly closed the object store first (so that the
`repack` process can delete the `.pack` files, which would otherwise not
be possible on Windows since files cannot be deleted as long as they as
still in use).
Wherever possible, we now use the new `close_object_store` bit of the
`run_command()` API, to delay closing the object store even further.
This makes the code easier to maintain because it is now more obvious
that we only release those file handles because of those child
processes.

On Windows, files cannot be removed nor renamed if there are still
handles held by a process. To remedy that, we try to release all open
handles to any `.pack` file before e.g. repacking (which would want to
remove the original `.pack` file(s) after it is done).
Since the `read_cache_unmerged()` and/or the `get_oid()` call in `git
pull` can cause `.pack` files to be opened, we need to release the open
handles before calling `git fetch`: the latter process might want to
spawn an auto-gc, which in turn might want to repack the objects.
This commit is similar in spirit to 5bdece0d705 (gc/repack: release
packs when needed, 2018-12-15).
This fixes https://github.com/git-for-windows/git/issues/3336.

the documentation to reflect that.
While at it, pass any `--signoff` flag through to the rebase backend too

There are both merge and rebase branches in the logic, and previously
both had to handle fast-forwarding. Merge handled that implicitly
(because git merge handles it directly), while in rebase it was
explicit. Given that the --ff-only flag is meant to override any
--rebase or --no-rebase, make the code reflect that by handling
--ff-only before the merge-vs-rebase logic.
It turns out that this also fixes a bug for submodules. Previously,
when --ff-only was given, the code would run `merge --ff-only` on the
main module, and then run `submodule update --recursive --rebase` on the
submodules. With this change, we still run `merge --ff-only` on the
main module, but now run `submodule update --recursive --checkout` on
the submodules. I believe this better reflects the intent of --ff-only
to have it apply to both the main module and the submodules.
(Sidenote: It is somewhat interesting that all merges pass `--checkout`
to submodule update, even when `--no-ff` is specified, meaning that it
will only do fast-forward merges for submodules. This was discussed in
commit a6d7eb2c7a ("pull: optionally rebase submodules (remote submodule
changes only)", 2017-06-23). The same limitations apply now as then, so
we are not trying to fix this at this time.)

Currently "git pull --rebase" takes a shortcut in the case a
fast-forward merge is possible; run_merge() is called with --ff-only.
However, "git merge" didn't have an --autostash option, so, when "git
pull --rebase --autostash" was called *and* the fast-forward merge
shortcut was taken, then the pull failed.
This was fixed in commit f15e7cf5cc (pull: ff --rebase --autostash
works in dirty repo, 2017-06-01) by simply skipping the fast-forward
merge shortcut.
Later on "git merge" learned the --autostash option [a03b55530a
(merge: teach --autostash option, 2020-04-07)], and so did "git pull"
[d9f15d37f1 (pull: pass --autostash to merge, 2020-04-07)].
Therefore it's not necessary to skip the fast-forward merge shortcut
anymore when called with --rebase --autostash.
Let's always take the fast-forward merge shortcut by essentially
reverting f15e7cf5cc.

|

In d18c950a69f (pull: warn if the user didn't say whether to rebase or
to merge, 2020-03-09), a new hint was introduced to encourage users to
make a conscious decision about whether they want their pull to merge or
to rebase by configuring the `pull.rebase` setting.
This warning was clearly intended to advise users, but as pointed out in
https://lore.kernel.org/git/87ima2rdsm.fsf%40evledraar.gmail.com, it
uses `warning()` instead of `advise()`.
One consequence is that the advice is not colorized in the same manner
as other, similar messages. So let's use `advise()` instead.

Ever since 'git pull' learned '--recurse-submodules' in a6d7eb2c7a
(pull: optionally rebase submodules (remote submodule changes only),
2017-06-23), we check if there are local submodule modifications by
checking the revision range 'curr_head --not rebase_fork_point'.
The goal of this check is to abort the pull if there are submodule
modifications in the local commits being rebased, since this scenario is
not supported.
However, the actual range of commits being rebased is not
'rebase_fork_point..curr_head', as the logic in
'get_rebase_newbase_and_upstream' reveals, it is 'upstream..curr_head'.
If the 'git merge-base --fork-point' invocation in
'get_rebase_fork_point' fails to find a fork point between the current
branch and the remote-tracking branch we are pulling from,
'rebase_fork_point' is null and since 4d36f88be7 (submodule: do not pass
null OID to setup_revisions, 2018-05-24), 'submodule_touches_in_range'
checks 'curr_head' and all its ancestors for submodule modifications.
Since it is highly likely that there are submodule modifications in this
range (which is in effect the whole history of the current branch), this
prevents 'git pull --rebase --recurse-submodules' from succeeding if no
fork point exists between the current branch and the remote-tracking
branch being pulled. This can happen, for example, when the current
branch was forked from a commit which was never recorded in the reflog
of the remote-tracking branch we are pulling, as the last two paragraphs
of the "Discussion on fork-point mode" section in git-merge-base(1)
explain.
Fix this bug by passing 'upstream' instead of 'rebase_fork_point' as the
'excl_oid' argument to 'submodule_touches_in_range'.

The function 'run_rebase' is responsible for constructing the
command line to be passed to 'git rebase'. This includes both forwarding
pass-through options given to 'git pull' as well computing the <newbase>
and <upstream> arguments to 'git rebase'.
A following commit will need to access the <upstream> argument in
'cmd_pull' to fix a bug with 'git pull --rebase --recurse-submodules'.
In order to do so, refactor the code so that the <newbase> and
<upstream> commits are computed in a new, separate function,
'get_rebase_newbase_and_upstream'.

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.

The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").
Note that we have to update all of the callers immediately. Playing

Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts all of the files in builtin/ to keep the diff to a
manageable size.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
and then selectively staging files with "git add builtin/". We'll deal
with any indentation/style fallouts separately.

In the codebase, there are many options which use OPTION_CALLBACK in a
plain ol' struct definition. However, we have the OPT_CALLBACK and
OPT_CALLBACK_F macros which are meant to abstract these plain struct
definitions away. These macros are useful as they semantically signal to
developers that these are just normal callback option with nothing fancy
happening.
Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or
OPT_CALLBACK_F where applicable. The heavy lifting was done using the
following (disgusting) shell script:
#!/bin/sh
do_replacement () {
tr '\n' '\r' |
sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' |

tr '\r' '\n'
}
for f in $(git ls-files \*.c)
do
do_replacement <"$f" >"$f.tmp"
mv "$f.tmp" "$f"
done
The result was manually inspected and then reformatted to match the
style of the surrounding code. Finally, using
`git grep OPTION_CALLBACK \*.c`, leftover results which were not handled
by the script were manually transformed.

We renamed the actual data structure in 910650d2f8 (Rename sha1_array to
oid_array, 2017-03-31), but the file is still called sha1-array. Besides
being slightly confusing, it makes it more annoying to grep for leftover
occurrences of "sha1" in various files, because the header is included
in so many places.
Let's complete the transition by renaming the source and header files
(and fixing up a few comment references).
I kept the "-" in the name, as that seems to be our style; cf.
fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10).
We also have oidmap.h and oidset.h without any punctuation, but those
are "struct oidmap" and "struct oidset" in the code. We _could_ make
this "oidarray" to match, but somehow it looks uglier to me because of
the length of "array" (plus it would be a very invasive patch for little
gain).

The fetch options --deepen, --negotiation-tip, --server-option,
--shallow-exclude, and --shallow-since are documented for git pull as
well, but are not actually accepted by that command. Pass them on to
make the code match its documentation.

When opt_rebase is true, we still first check if we can fast-forward.
If the branch is fast-forwardable, then we can avoid the rebase and just
use merge to do the fast-forward logic. However, when commit a6d7eb2c7a
("pull: optionally rebase submodules (remote submodule changes only)",
2017-06-23) added the ability to rebase submodules it accidentally
caused us to run BOTH a merge and a rebase. Add a flag to avoid doing
both.
This was found when a user had both pull.rebase and rebase.autosquash
set to true. In such a case, the running of both merge and rebase would
cause ORIG_HEAD to be updated twice (and match HEAD at the end instead
of the commit before the rebase started), against expectation.
