Have this file added in 06ba9d03e3 (t0051: test GIT_TRACE to a

existing Windows-only test added in 0e218f91c2 (mingw: unset PERL5LIB

This way TAP consumers like "prove" will show a nice summary when the
test is skipped. Instead of:
$ prove t0051-windows-named-pipe.sh
[...]
t0051-windows-named-pipe.sh .. ok
[...]
We will prominently show a "skipped" notice:
$ prove t0051-windows-named-pipe.sh
[...]
t0051-windows-named-pipe.sh ... skipped: skipping Windows-specific tests
[...]
This is because we are now making use of the right TAP-y way to
communicate this to the consumer. I.e. skipping the whole test file,
v.s. skipping individual tests (in this case there's only one test).

To improve the submodules UX, we would like to teach Git to handle
branches in submodules. Start this process by teaching "git branch" the
--recurse-submodules option so that "git branch --recurse-submodules
topic" will create the `topic` branch in the superproject and its
submodules.
Although this commit does not introduce breaking changes, it does not
work well with existing --recurse-submodules commands because "git
branch --recurse-submodules" writes to the submodule ref store, but most
commands only consider the superproject gitlink and ignore the submodule
ref store. For example, "git checkout --recurse-submodules" will check
out the commits in the superproject gitlinks (and put the submodules in
detached HEAD) instead of checking out the submodule branches.
Because of this, this commit introduces a new configuration value,
`submodule.propagateBranches`. The plan is for Git commands to
prioritize submodule ref store information over superproject gitlinks if
this value is true. Because "git branch --recurse-submodules" writes to
submodule ref stores, for the sake of clarity, it will not function
unless this configuration value is set.
This commit also includes changes that support working with submodules
from a superproject commit because "branch --recurse-submodules" (and
future commands) need to read .gitmodules and gitlinks from the
superproject commit, but submodules are typically read from the
filesystem's .gitmodules and the index's gitlinks. These changes are:
* add a submodules_of_tree() helper that gives the relevant
information of an in-tree submodule (e.g. path and oid) and
initializes the repository
* add is_tree_submodule_active() by adding a treeish_name parameter to
is_submodule_active()
* add the "submoduleNotUpdated" advice to advise users to update the
submodules in their trees
Incidentally, fix an incorrect usage string that combined the 'list'
usage of git branch (-l) with the 'create' usage; this string has been
incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use
parse_options., 2007-10-07).

Fix a bug that's been with us ever since 98a1364740 (trace2: log
progress time and throughput, 2020-05-12), when the
stop_progress_msg() API was used we didn't log a "region_leave" for
the "region_enter" we start in "start_progress_delay()".
The only user of the "stop_progress_msg()" function is
"index-pack". Let's add a previously failing test to check that we
have the same number of "region_enter" and "region_leave" events, with
"-v" we'll log progress even in the test environment.
In addition to that we've had a submarine bug here introduced with
9d81ecb52b (progress: add sparse mode to force 100% complete message,
2019-03-21). The "start_sparse_progress()" API would only do the right
thing if the progress was ended with "stop_progress()", not
"stop_progress_msg()".
The only user of that API uses "stop_progress()", but let's still fix
that along with the trace2 issue by making "stop_progress()" a trivial
wrapper for "stop_progress_msg()".
We can also drop the "if (progress)" test from
"finish_if_sparse()". It's now a helper for the small
"stop_progress_msg()" function. We'll already have returned from it if
"progress" is "NULL".

Normally diffs will contain a hunk header of the format
"@@ -2,2 +2,15 @@ code". However when there is only 1 line of
change, the unified diff format allows for the second comma
separated value to be omitted in either before or after
line counts.
This can produce hunk headers that look like
"@@ -2 +2,18 @@ code" or "@@ -2,2 +2 @@ code".
As a result, scan_hunk_header mistakenly returns the line
number as line count, which then results in unpredictable
parsing errors with the rest of the patch, including giving
multiple lines of output for a single commit.
Fix by explicitly setting line count to 1 when there is
no comma, and add a test.

Doing diffs for merges are special; they should typically avoid history
simplification. For example, with
git log --diff-merges=first-parent -- path
the default history simplification would remove merge commits from
consideration if the file "path" matched the second parent. That is
counter to what the user wants when looking for first-parent diffs.
Similar comments can be made for --diff-merges=separate (which diffs
against both parents) and --diff-merges=remerge (which diffs against a
remerge of the merge commit).
However, history simplification still makes sense if not doing diffing
merges, and it also makes sense for the combined and dense-combined
forms of diffing merges (because both of those are defined to only show
a diff when the merge result at the relevant paths differs from *both*
parents).
So, for separate, first-parent, and remerge styles of diff-merges, turn
off history simplification.

path_msg() has the ability to mark messages as omittable, designed for
remerge-diff where we'll instead be showing conflict messages as diff
headers for a subsequent diff. While all these messages are very useful
when trying to create a merge initially, early use with the
--remerge-diff feature (the only user of this omittable conflict message
capability), suggests that the particular messages marked in this commit
are just noise when trying to see what changes users made to create a
merge commit. Mark them as omittable.
Note that there were already a few messages marked as omittable in
merge-ort when doing a remerge-diff, because the development of
--remerge-diff preceded the upstreaming of merge-ort and I was trying to
ensure merge-ort could handle all the necessary requirements. See
commit c5a6f65527 ("merge-ort: add modify/delete handling and delayed

Instead of immediately printing ll-merge warnings to stderr, we save
them in our output strbuf. Besides allowing us to move these warnings
to a special file for --remerge-diff, this has two other benefits for
regular merges done by merge-ort:
* The deferral of messages ensures we can print all messages about
any given path together (merge-recursive was known to sometimes
intersperse messages about other paths, particularly when renames
were involved).
* The deferral of messages means we can avoid printing spurious
conflict messages when we just end up aborting due to local user
modifications in the way. (In contrast to merge-recursive.c which
prematurely checks for local modifications in the way via
unpack_trees() and gets the check wrong both in terms of false
positives and false negatives relative to renames, merge-ort does
not perform the local modifications in the way check until the
checkout() step after the full merge has been computed.)

Since some callers may want to send warning messages to somewhere other
than stdout/stderr, stop printing "warning: Cannot merge binary files"
from ll-merge and instead modify the return status of ll_merge() to
indicate when a merge of binary files has occurred. Message printing
probably does not belong in a "low-level merge" anyway.
This commit continues printing the message as-is, just from the callers
instead of within ll_merge(). Future changes will start handling the
message differently in the merge-ort codepath.
There was one special case here: the callers in rerere.c do NOT check
for and print such a message; since those code paths explicitly skip
over binary files, there is no reason to check for a return status of
LL_MERGE_BINARY_CONFLICT or print the related message.
Note that my methodology included first modifying ll_merge() to return
a struct, so that the compiler would catch all the callers for me and
ensure I had modified all of them. After modifying all of them, I then
changed the struct to an enum.

The --remerge-diff option will need to create new blobs and trees
representing the "automatic merge" state. If one is traversing a

loose objects generated during `log --remerge-diff`. However, none of
those loose objects are needed after we have completed our diff

When this option is specified, we remerge all (two parent) merge commits
and diff the actual merge commit to the automatically created version,
in order to show how users removed conflict markers, resolved the
different conflict versions, and potentially added new changes outside
of conflict regions in order to resolve semantic merge problems (or,
possibly, just to hide other random changes).
This capability works by creating a temporary object directory and
marking it as the primary object store. This makes it so that any blobs
or trees created during the automatic merge are easily removable
afterwards by just deleting all objects from the temporary object
directory.
There are a few ways that this implementation is suboptimal:
* `log --remerge-diff` becomes slow, because the temporary object
directory can fill with many loose objects while running
* the log output can be muddied with misplaced "warning: cannot merge
binary files" messages, since ll-merge.c unconditionally writes those
messages to stderr while running instead of allowing callers to
manage them.
* important conflict and warning messages are simply dropped; thus for
conflicts like modify/delete or rename/rename or file/directory which
are not representable with content conflict markers, there may be no
way for a user of --remerge-diff to know that there had been a
conflict which was resolved (and which possibly motivated other
changes in the merge commit).
* when fixing the previous issue, note that some unimportant conflict
and warning messages might start being included. We should instead
make sure these remain dropped.
Subsequent commits will address these issues.

override the config, then the override is ignored. Fix the bug by not
ignoring the value of "default".
Technically, before commit 3050b6dfc7, repo-settings would treat any
fetch.negotiationAlgorithm value other than "skipping" or "noop" as a
request for "default", but I think it probably makes more sense to
ignore such broken requests and leave fetch.negotiationAlgorithm with
the default value rather than the value of "default". (If that sounds
confusing, note that "default" is usually the default value, but when
feature.experimental=true, "skipping" is the default value.)

Fix misbehavior in Git.pm that dates back to the very first version of

signals, those can happen e.g. if abort() is called, or if the command
segfaults.
Because of this we'd consider e.g. a command that died due to LSAN
exiting with abort() successful, as is the case with the tests listed
as running successfully with SANITIZE=leak in 9081a421a6 (checkout:

we'd have a "$? >> 8" of "23" on failure, with abort_on_error=1 we'll

the "pre-receive" hook to purge that temporary data in the quarantine
area when there is no command ready to run.
The reason we do not add the checkpoint before the "pre-receive" hook,
but after it, is that the "pre-receive" hook is called with a switch-off
"skip_broken" flag, and all commands, even broken ones, should be fed
by calling "feed_receive_hook()".
Add a new test case in t5516 as well.

Consolidate the logic for deciding when to create a new branch in
cmd_branch(), and save the result for reuse. Besides making the function
more explicit, this allows us to validate options that can only be used
when creating a branch. Such an option does not exist yet, but one will
be introduced in a subsequent commit.

Add a dry_run parameter to create_branch() such that dry_run = 1 will
validate a new branch without trying to create it. This will be used in
`git branch --recurse-submodules` to ensure that the new branch can be
created in all submodules.

With the previous commit, there are no more invocations of
create_branch() that do not create a branch because:
* BRANCH_TRACK_OVERRIDE is no longer passed
* clobber_head_ok = true and force = false is never passed
Assert these situations, delete dead code and ensure that we're handling
clobber_head_ok and force correctly by introducing tests for `git branch
--force`. As a result, create_branch() now always creates a branch.

This commit is preparation for a future commit that will simplify
create_branch() so that it always creates a branch. This will allow
create_branch() to accept a dry_run parameter (which is needed for "git
branch --recurse-submodules").
create_branch() used to always create a branch, but 4fc5006676 (Add
branch --set-upstream, 2010-01-18) changed it to also be able to set
tracking information without creating a branch.
Refactor the code that sets tracking information into its own functions
dwim_branch_start() and dwim_and_setup_tracking(). Also change an
invocation of create_branch() in cmd_branch() in builtin/branch.c to use
dwim_and_setup_tracking(), since that invocation is only for setting
tracking information (in "git branch --set-upstream-to").
As of this commit, create_branch() is no longer invoked in a way that
does not create branches.

When `merge.ff` is set to `only` in .gitconfig, `git subtree pull` will
fail with error `fatal: Not possible to fast-forward, aborting.`, but
the command does want to make merges in these places. Add `--no-ff`
argument to `git merge` to enforce this behaviour.

When pruning refs fails, we print an error to stderr, but still
exit 0 from 'git fetch'. Since this is a genuine error, fetch
should be exiting with some non-zero exit code. Make it so.
The --prune option was introduced in f360d844de ("builtin-fetch: add
--prune option", 2009-11-10). Unfortunately it's unclear from that
commit whether ignoring the exit code was an oversight or
intentional, but it feels like an oversight.
