fetch_objects() spawns a child `git fetch` to lazily fill in missing
objects. That child's index-pack, when it receives a thin pack
containing a REF_DELTA against a still-missing base, explicitly
calls promisor_remote_get_direct() — which is fetch_objects() again.
If the base is truly unavailable (e.g. because many refs in the
local store point at objects that have been garbage-collected on the
server), each recursive lazy-fetch can trigger another, leading to
unbounded recursion with runaway disk and process consumption.
The GIT_NO_LAZY_FETCH guard (introduced by e6d5479e7a (git: add
--no-lazy-fetch option, 2021-08-31)) already exists at the top of
fetch_objects(); the missing piece is propagating it into the child
fetch's environment. Add that propagation so the child's
index-pack, if it encounters a REF_DELTA against a missing base,
hits the guard and fails fast instead of recursing.
Depth-1 lazy fetch (the whole point of fetch_objects()) is
unaffected: only the child and its descendants see the variable.
With negotiationAlgorithm=noop the client advertises no "have"
lines, so a well-behaved server sends requested objects
un-deltified or deltified only against objects in the same pack;
the child's index-pack should never need a depth-2 fetch. If it
does, the server response was broken or the local store is already
corrupt, and further fetching would not help.
This is the same bug shape that 3a1ea94a49 (commit-graph.c: no lazy
fetch in lookup_commit_in_graph(), 2022-07-01) addressed at a
different entry point.
Add a test that verifies the child fetch environment contains
GIT_NO_LAZY_FETCH=1 via a reference-transaction hook.

Add a smoke test that verifies the filesystem actually delivers
inotify events to the daemon. On some configurations (e.g.,
overlayfs with older kernels), inotify watches succeed but events
are never delivered. The daemon cookie wait will time out, but
every subsequent test would fail. Skip the entire test file early
when this is detected.
Add a test that exercises rapid nested directory creation to verify
the daemon correctly handles the EEXIST race between recursive scan
and queued inotify events. When IN_MASK_CREATE is available and a
directory watch is added during recursive registration, the kernel
may also deliver a queued IN_CREATE event for the same directory.
The second inotify_add_watch() returns EEXIST, which must be treated
as harmless. An earlier version of the listener crashed in this
scenario.
Reduce --start-timeout from the default 60 seconds to 10 seconds so
that tests fail promptly when the daemon cannot start.
Harden the test helpers to work in environments without procps
(e.g., Fedora CI): fall back to reading /proc/$pid/stat for the
process group ID when ps is unavailable, guard stop_git() against
an empty pgid, and redirect stderr from kill to /dev/null to avoid
noise when processes have already exited.
Use set -m to enable job control in the submodule-pull test so that
the background git pull gets its own process group, preventing the
shell wait from blocking on the daemon. setsid() in the previous
commit detaches the daemon itself, but the intermediate git pull
process still needs its own process group for the test shell to
manage it correctly.

'read_gitfile_gently()' treats any non-regular file as
'READ_GITFILE_ERR_NOT_A_FILE' and fails to discern between 'ENOENT'
and other stat failures. This flawed error reporting is noted by two
'NEEDSWORK' comments.
Address these comments by introducing two new error codes:
'READ_GITFILE_ERR_MISSING'(which groups the "file missing" scenarios
together) and 'READ_GITFILE_ERR_IS_A_DIR':
1. Update 'read_gitfile_error_die()' to treat 'IS_A_DIR', 'MISSING',
'NOT_A_FILE' and 'STAT_FAILED' as non-fatal no-ops. This accommodates
intentional non-repo scenarios (e.g., GIT_DIR=/dev/null).
2. Explicitly catch 'NOT_A_FILE' and 'STAT_FAILED' during
discovery and call 'die()' if 'die_on_error' is set.
3. Unconditionally pass '&error_code' to 'read_gitfile_gently()'.
4. Only invoke 'is_git_directory()' when we explicitly receive
'READ_GITFILE_ERR_IS_A_DIR', avoiding redundant checks.
Additionally, audit external callers of 'read_gitfile_gently()' in
'submodule.c' and 'worktree.c' to accommodate the refined error codes.

When be76c21282 (fetch: ensure submodule objects fetched, 2018-12-06)
added support for fetching a missing submodule object by id, it
hardcoded the remote name as "origin" and deferred anything more
complicated for a later patch. Implement the NEEDSWORK item to remove
the hardcoded assumption by adding and using a submodule helper subcmd
'get-default-remote'. Fixing this lets 'git fetch --recurse-submodules'
succeed when the fetched commit(s) in the superproject trigger a
submodule fetch, and that submodule's default remote name is not
"origin".
Add non-"origin" remote tests to t5526-fetch-submodules.sh and
t5572-pull-submodule.sh demonstrating this works as expected and add
dedicated tests for get-default-remote.

It is quite a common use case that one wants to split up one commit into
multiple commits by moving parts of the changes of the original commit
out into a separate commit. This is quite an involved operation though:
1. Identify the commit in question that is to be dropped.
2. Perform an interactive rebase on top of that commit's parent.
3. Modify the instruction sheet to "edit" the commit that is to be
split up.
4. Drop the commit via "git reset HEAD~".
5. Stage changes that should go into the first commit and commit it.
6. Stage changes that should go into the second commit and commit it.
7. Finalize the rebase.
This is quite complex, and overall I would claim that most people who
are not experts in Git would struggle with this flow.
Introduce a new "split" subcommand for git-history(1) to make this way
easier. All the user needs to do is to say `git history split $COMMIT`.
From hereon, Git asks the user which parts of the commit shall be moved
out into a separate commit and, once done, asks the user for the commit
message. Git then creates that split-out commit and applies the original
commit on top of it.

Replace 'grep' and '! grep' invocations with 'test_grep' and

in the future, as 'test_grep' will automatically print the
contents of the file when a check fails.
While at it, update any remaining instances of 'grep' to 'test_grep'
that were missed in the previous versions to ensure that the entire

Replace pipelines involving git commands with temporary files (actual)
to ensure that any crashes or unexpected exit codes from the git
commands are properly caught by the test suite. A simple pipeline
like 'git foo | grep bar' ignores the exit code of 'git', which
can hide regressions.
In cases where we were counting lines with 'wc -l' to ensure a
pattern was absent, simplify the logic to use '! grep' to avoid
subshells entirely.
