"git clone --reject-shallow" option fails the clone as soon as we
notice that we are cloning from a shallow repository.
* ll/clone-reject-shallow:
builtin/clone.c: add --reject-shallow option
|
|
In some scenarios, users may want more history than the repository
offered for cloning, which happens to be a shallow repository, can
give them. But because users don't know it is a shallow repository
until they download it to local, we may want to refuse to clone
this kind of repository, without creating any unnecessary files.
The '--depth=x' option cannot be used as a solution; the source may
be deep enough to give us 'x' commits when cloned, but the user may
later need to deepen the history to arbitrary depth.
Teach '--reject-shallow' option to "git clone" to abort as soon as
we find out that we are cloning from a shallow repository.

When writing a new pack with a bitmap, it is sometimes convenient to
indicate some reference prefixes which should receive priority when
selecting which commits to receive bitmaps.
A truly motivated caller could accomplish this by setting
'pack.islandCore', (since all commits in the core island are similarly
marked as preferred) but this requires callers to opt into using delta
islands, which they may or may not want to do.
Introduce a new multi-valued configuration, 'pack.preferBitmapTips' to
allow callers to specify a list of reference prefixes. All references
which have a prefix contained in 'pack.preferBitmapTips' will mark their
tips as "preferred" in the same way as commits are marked as preferred
for selection by 'pack.islandCore'.
The choice of the verb "prefer" is intentional: marking the NEEDS_BITMAP
flag on an object does *not* guarantee that that object will receive a
bitmap. It merely guarantees that that commit will receive a bitmap over
any *other* commit in the same window by bitmap_writer_select_commits().
The test this patch adds reflects this quirk, too. It only tests that
a commit (which didn't receive bitmaps by default) is selected for
bitmaps after changing the value of 'pack.preferBitmapTips' to include
it. Other commits may lose their bitmaps as a byproduct of how the
selection process works (bitmap_writer_select_commits() ignores the
remainder of a window after seeing a commit with the NEEDS_BITMAP flag).
This configuration will aide in selecting important references for
multi-pack bitmaps, since they do not respect the same pack.islandCore
configuration. (They could, but doing so may be confusing, since it is
packs--not bitmaps--which are influenced by the delta-islands
configuration).
In a fork network repository (one which lists all forks of a given
repository as remotes), for example, it is useful to set
pack.preferBitmapTips to 'refs/remotes/<root>/heads' and
'refs/remotes/<root>/tags', where '<root>' is an opaque identifier
referring to the repository which is at the base of the fork chain.

Remove the rebase.useBuiltin setting and the now-obsolete
GIT_TEST_REBASE_USE_BUILTIN test flag.
This was left in place after my d03ebd411c6 (rebase: remove the
rebase.useBuiltin setting, 2019-03-18) to help anyone who'd used the
experimental flag and wanted to know that it was the default, or that
they should transition their test environment to use the builtin
rebase unconditionally.
It's been more than long enough for those users to get a headsup about
this. So remove all the scaffolding that was left inplace after
d03ebd411c6. I'm also removing the documentation entry, if anyone
still has this left in their configuration they can do some source
archaeology to figure out what it used to do, which makes more sense
than exposing every git user reading the documentation to this legacy
configuration switch.

Disable the recent mergetool's hideresolved feature by default for
backward compatibility and safety.
* jn/mergetool-hideresolved-is-optional:
doc: describe mergetool configuration in git-mergetool(1)
mergetool: do not enable hideResolved by default
|
|
When 98ea309b3f (mergetool: add hideResolved configuration,
2021-02-09) introduced the mergetool.hideResolved setting to reduce
the clutter in viewing non-conflicted sections of files in a
mergetool, it enabled it by default, explaining:
No adverse effects were noted in a small survey of popular mergetools[1]
so this behavior defaults to `true`.
In practice, alas, adverse effects do appear. A few issues:
1. No indication is shown in the UI that the base, local, and remote
versions shown have been modified by additional resolution. This
is inherent in the design: the idea of mergetool.hideResolved is to
convince a mergetool that expects pristine local, base, and remote
files to show partially resolved verisons of those files instead;
there is no additional source of information accessible to the
mergetool to see where the resolution has happened.
(By contrast, a mergetool generating the partial resolution from
conflict markers for itself would be able to hilight the resolved
sections with a different color.)
A user accustomed to seeing the files without partial resolution
gets no indication that this behavior has changed when they upgrade
Git.
2. If the computed merge did not line up the files correctly (for
example due to repeated sections in the file), the partially
resolved files can be misleading and do not have enough information
to reconstruct what happened and compute the correct merge result.
3. Resolving a conflict can involve information beyond the textual
conflict. For example, if the local and remote versions added
overlapping functionality in different ways, seeing the full
unresolved versions of each alongside the base gives information
about each side's intent that makes it possible to come up with a
resolution that combines those two intents. By contrast, when
starting with partially resolved versions of those files, one can
produce a subtly wrong resolution that includes redundant extra
code added by one side that is not needed in the approach taken
on the other.
All that said, a user wanting to focus on textual conflicts with
reduced clutter can still benefit from mergetool.hideResolved=true as
a way to deemphasize sections of the code that resolve cleanly without
requiring any changes to the invoked mergetool. The caveats described
above are reduced when the user has explicitly turned this on, because
then the user is aware of them.
Flip the default to 'false'.

We have two established generation number versions:
1: topological levels
2: corrected commit dates
The corrected commit dates are enabled by default, but they also write
extra data in the GDAT and GDOV chunks. Services that host Git data
might want to have more control over when this feature rolls out than
just updating the Git binaries.
Add a new "commitGraph.generationVersion" config option that specifies
the intended generation number version. If this value is less than 2,
then the GDAT chunk is never written _or read_ from an existing file.
This can replace our use of the GIT_TEST_COMMIT_GRAPH_NO_GDAT
environment variable in the test suite. Remove it.

Add a per-tool override flag so that users may enable the flag for one
tool and disable it for another by setting
`mergetool.<tool>.hideResolved` to `false`.
In addition, the author or maintainer of a mergetool may optionally
override the default `hideResolved` value for that mergetool. If the
`mergetools/<tool>` shell script contains a `hide_resolved_enabled`
function it will be called when the mergetool is invoked and the return
value will be used as the default for the `hideResolved` flag.
hide_resolved_enabled () {
return 1
}
Disabling may be desirable if the mergetool wants or needs access to the
original, unmodified 'LOCAL' and 'REMOTE' versions of the conflicted
file. For example:
- A tool may use a custom conflict resolution algorithm and prefer to
ignore the results of Git's conflict resolution.
- A tool may want to visually compare/constrast the version of the file
from before the merge (saved to 'LOCAL', 'REMOTE', and 'BASE') with
Git's conflict resolution results (saved to 'MERGED').

The purpose of a mergetool is to help the user resolve any conflicts
that Git cannot automatically resolve. If there is a conflict that must
be resolved manually Git will write a file named MERGED which contains
everything Git was able to resolve by itself and also everything that it
was not able to resolve wrapped in conflict markers.
One way to think of MERGED is as a two- or three-way diff. If each
"side" of the conflict markers is separately extracted an external tool
can represent those conflicts as a side-by-side diff.
However many mergetools instead diff LOCAL and REMOTE both of which
contain versions of the file from before the merge. Since the conflicts
Git resolved automatically are not present it forces the user to
manually re-resolve those conflicts. Some mergetools also show MERGED
but often only for reference and not as the focal point to resolve the
conflicts.
This adds a `mergetool.hideResolved` flag that will overwrite LOCAL and
REMOTE with each corresponding "side" of a conflicted file and thus hide
all conflicts that Git was able to resolve itself. Overwriting these
files will immediately benefit any mergetool that uses them without
requiring any changes to the tool.
No adverse effects were noted in a small survey of popular mergetools[1]
so this behavior defaults to `true`. However it can be globally disabled
by setting `mergetool.hideResolved` to `false`.

Teach Git to use the "unborn" feature introduced in a previous patch as

all other cases, Git will ignore it.

When cloning, we choose the default branch based on the remote HEAD.
But if there is no remote HEAD reported (which could happen if the
target of the remote HEAD is unborn), we'll fall back to using our local
init.defaultBranch. Traditionally this hasn't been a big deal, because
most repos used "master" as the default. But these days it is likely to
cause confusion if the server and client implementations choose
different values (e.g., if the remote started with "main", we may choose
"master" locally, create commits there, and then the user is surprised
when they push to "master" and not "main").
To solve this, the remote needs to communicate the target of the HEAD
symref, even if it is unborn, and "git clone" needs to use this
information.
Currently, symrefs that have unborn targets (such as in this case) are
not communicated by the protocol. Teach Git to advertise and support the
"unborn" feature in "ls-refs" (by default, this is advertised, but
server administrators may turn this off through the lsrefs.unborn
config). This feature indicates that "ls-refs" supports the "unborn"
argument; when it is specified, "ls-refs" will send the HEAD symref with
the name of its unborn target.
This change is only for protocol v2. A similar change for protocol v0
would require independent protocol design (there being no analogous
position to signal support for "unborn") and client-side plumbing of the
data required, so the scope of this patch set is limited to protocol v2.
The client side will be updated to use this in a subsequent commit.

Git diff reports a submodule directory as -dirty even when there are
only untracked files in the submodule directory. This is inconsistent
with what `git describe --dirty` says when run in the submodule
directory in that state.
Make `--ignore-submodules=untracked` the default for `git diff` when
there is no configuration variable or command line option, so that the
command would not give '-dirty' suffix to a submodule whose working
tree has untracked files, to make it consistent with `git
describe --dirty` that is run in the submodule working tree.
And also make `--ignore-submodules=none` the default for `git status`
so that the user doesn't end up deleting a submodule that has
uncommitted (untracked) files.

For the past 15 years, we've used the hardcoded 64 as the length
limit of the filename of the output from the "git format-patch"
command. Since the value is shorter than the 80-column terminal, it
could grow without line wrapping a bit. At the same time, since the
value is longer than half of the 80-column terminal, we could fit
two or more of them in "ls" output on such a terminal if we allowed
to lower it.
Introduce a new command line option --filename-max-length=<n> and a
new configuration variable format.filenameMaxLength to override the
hardcoded default.
While we are at it, remove a check that the name of output directory
does not exceed PATH_MAX---this check is pointless in that by the
time control reaches the function, the caller would already have
done an equivalent of "mkdir -p", so if the system does not like an
overly long directory name, the control wouldn't have reached here,
and otherwise, we know that the system allowed the output directory
to exist. In the worst case, we will get an error when we try to
open the output file and handle the error correctly anyway.

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.

To provide an on-ramp for users to use background maintenance without
several 'git config' commands, create a 'maintenance.strategy' config
option. Currently, the only important value is 'incremental' which
assigns the following schedule:
* gc: never
* prefetch: hourly
* commit-graph: hourly
* loose-objects: daily
* incremental-repack: daily
These tasks are chosen to minimize disruptions to foreground Git
commands and use few compute resources.
The 'maintenance.strategy' is intended as a baseline that can be
customzied further by manually assigning 'maintenance.<task>.enabled'
and 'maintenance.<task>.schedule' config options, which will override
any recommendation from 'maintenance.strategy'. This operates similarly
to config options like 'feature.experimental' which operate as "meta"
config options that change default config values.
This presents a way forward for updating the 'incremental' strategy in
the future or adding new strategies. For example, a potential strategy
could be to include a 'full' strategy that runs the 'gc' task weekly
and no other tasks by default.
