Refactor the tests in preparation for adding more tests in the next
few commits. The reworked tests use the same function for testing both
the "merge" and "apply" backends. The test coverage for the "apply"
backend now includes setting GIT_REFLOG_ACTION.
Note that rebasing the "conflicts" branch does not create any
conflicts yet. A commit to do that will be added in the next commit
and the diff ends up smaller if we have don't rename the branch when
it is added.

Use move_to_original_branch() when reattaching HEAD after a fast-forward
rather than open coding a copy of that code. move_to_original_branch()
does not call reset_head() if head_name is NULL but there should be no
user visible changes even though we currently call reset_head() in that
case. The reason for this is that the reset_head() call does not add a
message to the reflog because we're not changing the commit that HEAD
points to and so lock_ref_for_update() elides the update. When head_name
is not NULL then reset_head() behaves like "git symbolic-ref" and so the
reflog is updated.
Note that the removal of "strbuf_release(&msg)" is safe as there is an
identical call just above this hunk which can be seen by viewing the
diff with -U6.

* pw/rebase-keep-base-fixes:
rebase --keep-base: imply --no-fork-point
rebase --keep-base: imply --reapply-cherry-picks
rebase: factor out branch_base calculation
rebase: rename merge_base to branch_base
rebase: store orig_head as a commit
rebase: be stricter when reading state files containing oids
t3416: set $EDITOR in subshell
t3416: tighten two tests
|
|
Given the name of the option it is confusing if --keep-base actually
changes the base of the branch without --fork-point being explicitly
given on the command line.
The combination of --keep-base with an explicit --fork-point is still
supported even though --fork-point means we do not keep the same base
if the upstream branch has been rewound. We do this in case anyone is
relying on this behavior which is tested in t3431[1]

As --keep-base does not rebase the branch it is confusing if it
removes commits that have been cherry-picked to the upstream branch.
As --reapply-cherry-picks is not supported by the "apply" backend this
commit ensures that cherry-picks are reapplied by forcing the upstream
commit to match the onto commit unless --no-reapply-cherry-picks is
given.

Separate out calculating the merge base between 'onto' and 'HEAD' from
the check for whether we can fast-forward or not. This means we can skip
the fast-forward checks when the rebase is forced and avoid calculating
the merge-base between 'HEAD' and 'onto' when --keep-base is given.

Using a struct commit rather than a struct oid to hold orig_head means
that we error out straight away if the branch being rebased does not
point to a commit. It also simplifies the code that handles finding
the merge base and fork point as it no longer has to convert from an
oid to a commit.
To avoid changing the behavior of "git rebase <upstream> <branch>" we
keep the existing call to read_ref() and use lookup_commit_object()
on the oid returned by that rather than calling
lookup_commit_reference_by_name() which applies the ref dwim rules to
its argument.

The state files for 'onto' and 'orig_head' should contain a full hex
oid, change the reading functions from get_oid() to get_oid_hex() to
reflect this. They should also name commits and not tags so add and use
a function that looks up a commit from an oid like
lookup_commit_reference() but without dereferencing tags.

When debugging bitmap generation performance, it is useful to know how
many bitmaps were generated from scratch, and how many were the result
of permuting the bit-order of an existing bitmap.
Keep track of the latter, and emit the count as a trace2_data line to
aid in debugging.

When debugging MIDX and MIDX-bitmap related issues, it is useful to
figure out where Git is spending its time.
GitHub has been using the below trace2 regions to instrument various
components of generating a MIDX itself, as well time spent preparing to
build a MIDX bitmap.
These are limited to instrumenting the following functions:
- midx.c::find_commits_for_midx_bitmap()
- midx.c::midx_pack_order()
- midx.c::prepare_midx_packing_data()
- midx.c::write_midx_bitmap()
- midx.c::write_midx_internal()
- midx.c::write_midx_reverse_index()
to start and end with a trace2_region_enter() and trace2_region_leave(),
respectively.
The category for all of these is "midx", which matches the existing
convention. The region description matches the name of the function.

When generating a multi-pack bitmap without a `--refs-snapshot` (e.g.,
by running `git multi-pack-index write --bitmap` directly), we determine
the set of bitmap-able commits by enumerating each reference, and adding
the referrent as the tip of a reachability traversal when it appears
somewhere in the MIDX. (Any commit we encounter during the reachability
traversal then becomes a candidate for bitmap selection).
But we incorrectly avoid peeling the object at the tip of each
reference. So if we see some reference that points at an annotated tag
(which in turn points through zero or more additional annotated tags at
a commit), that we will not add it as a tip for the reachability
traversal. This means that if some commit C is only referenced through
one or more annotated tag(s), then C won't become a bitmap candidate.
Correct this by peeling the reference tips as we enumerate them to
ensure that we consider commits which are the targets of annotated tags,
in addition to commits which are referenced directly.

Protected config is implemented by reading a fixed set of paths,
which ignores config [include]-s. Replace this implementation with a
call to config_with_options(), which handles [include]-s and saves us
from duplicating the logic of 1) identifying which paths to read and 2)
reading command line config.
As a result, git_configset_add_parameters() is unused, so remove it. It
was introduced alongside protected config in 5b3c650777 (config: learn
`git_protected_config()`, 2022-07-14) as a way to handle command line
config.

Add a test for the *.txt and *.c output assertions which asserts that
for "-h" lines that aren't the "usage: " or " or: " lines they start
with the same amount of whitespace. This ensures that we won't have
buggy output like:
[...]
or: git tag [-n[<num>]]
[...]
[--create-reflog] [...]
Which should instead be like this, i.e. the options lines should be
aligned:
[...]
or: git tag [-n[<num>]]
[...]
[--create-reflog] [...]
It would be better to be able to use "test_cmp" here, i.e. to
construct the output we expect, and compare it against the actual
output.
For most built-in commands this would be rather straightforward. In
"t0450-txt-doc-vs-help.sh" we already compute the whitespace that a
"git-$builtin" needs, and strip away "usage: " or " or: " from the
start of lines. The problem is:
* For commands that implement subcommands, such as "git bundle", we
don't know whether e.g. "git bundle create" is the subcommand
"create", or the argument "create" to "bundle" for the purposes of
alignment.
We *do* have that information from the *.txt version, since the
part within the ''-quotes should be the command & subcommand, but
that isn't consistent (e.g. see "git bundle" and "git
commit-graph", only the latter is correct), and parsing that out
would be non-trivial.
* If we were to make this stricter we have various
non-parse_options() users (e.g. "git diff-tree") that don't have the
nicely aligned output which we've had since
4631cfc20bd (parse-options: properly align continued usage output,
2021-09-21).
So rather than make perfect the enemy of the good let's assert that
for those lines that are indented they should all use the same
indentation.

There's been a lot of incremental effort to make the SYNOPSIS output
in our documentation consistent with the -h output,
e.g. cbe485298bf (git reflog [expire|delete]: make -h output
consistent with SYNOPSIS, 2022-03-17) is one recent example, but that
effort has been an uphill battle due to the lack of regression
testing.
This adds such regression testing, we can parse out the SYNOPSIS
output with "sed", and it turns out it's relatively easy to normalize
it and the "-h" output to match on another.
We now ensure that we won't have regressions when it comes to the list
of commands in "expect_help_to_match_txt" below, and in subsequent
commits we'll make more of them consistent.
The naïve parser here gets quite a few things wrong, but it doesn't
need to be perfect, just good enough that we can compare /some/ of
this help output. There's no cases where the output would match except
for the parser's stupidity, it's all cases of e.g. comparing the *.txt
to non-parse_options() output.
Since that output is wildly different than the *.txt anyway let's
leave this for now, we can fix the parser some other time, or it won't
become necessary as we'll e.g. convert more things to using
parse_options().
Having a special-case for "merge-tree"'s 1f0c3a29da3 (merge-tree:
implement real merges, 2022-06-18) is a bit ugly, but preferred to
blessing that " (deprecated)" pattern for other commands. We'd
probably want to add some other way of marking deprecated commands in
the SYNOPSIS syntax. Syntactically 1f0c3a29da3's way of doing it is
indistinguishable from the command taking an optional literal
"deprecated" string as an argument.
Some of the issues that are left:
* "git show -h", "git whatchanged -h" and "git reflog --oneline -h"
all showing "git log" and "git show" usage output. I.e. the
"builtin_log_usage" in builtin/log.c doesn't take into account what
command we're running.
* Commands which implement subcommands such as like
"multi-pack-index", "notes", "remote" etc. having their subcommands
in a very different order in the *.txt and *.c. Fixing it would
require some verbose diffs, so it's been left alone for now.
* Commands such as "format-patch" have a very long argument list in
the *.txt, but just "[<options>]" in the *.c.
What to do about these has been left out of this series, except to
the extent that preceding commits changed "[<options>]" (or
equivalent) to the list of options in cases where that list of
options was tiny, or we clearly meant to exhaustively list the
options in both *.txt and *.c.

This syntax issue for "bugreport" originated in

The "stash" issue has been with us in both the "-h" and *.txt versions
since bd514cada4b (stash: introduce 'git stash store', 2013-06-15).
We could claim that this isn't a syntax issue if a "vertical bar binds
tighter than option and its argument", but such a rule would change
e.g. this "cat-file" SYNOPSIS example to mean something we don't:
... [<rev>:<path|tree-ish> | --path=<path|tree-ish> <rev>]
We have various other examples where the post-image here is already
used, e.g. for "format-patch" ("-o"), "grep" ("-m"),
"submodule" ("set-branch -b") etc.

Change the documentation and -h output for those built-in commands
where both the -h output and *.txt were lacking in word-wrapping.
There are many more built-ins that could use this treatment, this
change is narrowed to those where this whitespace change is needed to
make the -h and *.txt consistent in the end.
In the case of "Documentation/git-hash-object.txt" and
"builtin/hash-object.c" this is not a "doc txt & -h consistency"
change, as we're changing both versions, doing so here makes a
subsequent change smaller.

Change commands in the "diff" family and "rev-list" to separate the
usage information and option listing with an empty line.
In the case of "git diff -h" we did this already (but let's use a
consistent "\n" pattern there), for the rest these are now consistent
with how the parse_options() API would emit usage.
As we'll see in a subsequent commit this also helps to make the "git
<cmd> -h" output more easily machine-readable, as we can assume that
the usage information is separated from the options by an empty line.
Note that "COMMON_DIFF_OPTIONS_HELP" starts with a "\n", so the
seeming omission of a "\n" here is correct, the second one is provided
by the macro.

Most of our commands use ''-quotation only for the name of the command
itself, and not its (optional) arguments. Let's do the same for these.

Almost all of our documentation doesn't use "'" syntax for
subcommands, but these did, let's make them consistent with the
rest.

Avoid repeating the "-h" output for the "git bundle" command, and
instead define the usage of each subcommand with macros, so that the
"-h" output for the command itself can re-use those definitions. See
[1], [2] and [3] for prior art using the same pattern.

Edit the section which explains how to create a good SYNOPSIS section
for clarity and accuracy, it was mostly introduced in
c455bd8950e (CodingGuidelines: Add a section on writing documentation,
2010-11-04):
* Change "extra" example to "file", which now naturally follows from
previous "<file>..." example (one or more) to "[<file>...]" (zero or
more).
* Explain how we prefer spacing around "[]()" tokens and "|"
alternatives, this is not a new policy, but just codifies what's
already the pattern in the most wide use in the documentation.
Having a space around " | " for flags, but not for flag values is
inconsistent, but this style guide codifies existing
patterns. Grepping shows that we don't have any instance matching the
second "Don't" example:
git grep -E -h -o '=\([^)]+\)' -- builtin Documentation/
