"git rev-parse --exclude=* --branches --branches" (i.e. first

In find_non_local_tags() helper function (used to implement the
"follow tags"), we use string_list_has_string() on two string lists
as a way to see if a refname has already been processed, etc.
All this code predates more modern in-core lookup API like hashmap;
replace them with two hashmaps and one string list---the hashmaps
are used for look-ups and the string list is to keep the order of
items in the returned result stable (which is the only single thing
hashmap does worse than lookups on string-list).
Similarly, get_ref_map() uses another string-list as a look-up table
for existing refs. Replace it with a hashmap.

When the .gitmodules file is not available in the working tree, try
using the content from the index and from the current branch. This
covers the case when the file is part of the repository but for some
reason it is not checked out, for example because of a sparse checkout.
This makes it possible to use at least the 'git submodule' commands
which *read* the gitmodules configuration file without fully populating
the working tree.
Writing to .gitmodules will still require that the file is checked out,
so check for that before calling config_set_in_gitmodules_file_gently.
Add a similar check also in git-submodule.sh::cmd_add() to anticipate
the eventual failure of the "git submodule add" command when .gitmodules
is not safely writeable; this prevents the command from leaving the
repository in a spurious state (e.g. the submodule repository was cloned
but .gitmodules was not updated because
config_set_in_gitmodules_file_gently failed).
Moreover, since config_from_gitmodules() now accesses the global object
store, it is necessary to protect all code paths which call the function
against concurrent access to the global object store. Currently this
only happens in builtin/grep.c::grep_submodules(), so call
grep_read_lock() before invoking code involving
config_from_gitmodules().
Finally, add t7418-submodule-sparse-gitmodules.sh to verify that reading
from .gitmodules succeeds and that writing to it fails when the file is
not checked out.
NOTE: there is one rare case where this new feature does not work
properly yet: nested submodules without .gitmodules in their working
tree. This has been documented with a warning and a test_expect_failure
item in t7814, and in this case the current behavior is not altered: no
config is read.

Unlike its arbitrary text patterns, the --heads and --tags
options to ls-remote are true prefixes. We can pass this
information to the transport code. If the v2 protocol is in
use, that will reduce the size of the ref advertisement.
Note that the test added here succeeds both before and after
the patch. This is an optimization, not a bug-fix; it's just
making sure we didn't break anything.

Since b4be74105f (ls-remote: pass ref prefixes when requesting a
remote's refs, 2018-03-15), "ls-remote foo" will pass "refs/heads/foo",
"refs/tags/foo", etc to the transport code in an attempt to let the
other side reduce the size of its advertisement.
Unfortunately this is not correct, as ls-remote patterns do not follow
the usual ref lookup rules, and are in fact tail-matched. So we could
find "refs/heads/foo" or "refs/heads/a/much/deeper/foo" or even
"refs/another/hierarchy/foo".
Since we can't pass a prefix and there's not yet a v2 extension for
matching wildcards, we must disable this feature to keep the same
behavior as v1.

cat-file: handle streaming failures consistently
check_stream_sha1(): handle input underflow
t1450: check large blob in trailing-garbage test
|
|
There are three ways to convince cat-file to stream a blob:
- cat-file -p $blob
- cat-file blob $blob
- echo $batch | cat-file --batch
In the first two, we simply exit with the error code of
streaw_blob_to_fd(). That means that an error will cause us
to exit with "-1" (which we try to avoid) without printing
any kind of error message (which is confusing to the user).
Instead, let's match the third case, which calls die() on an
error. Unfortunately we cannot be more specific, as
stream_blob_to_fd() does not tell us whether the problem was
on reading (e.g., a corrupt object) or on writing (e.g.,
ENOSPC). That might be an opportunity for future work, but
for now we will at least exit with a sane message and exit
code.

"git cmd --help" when "cmd" is aliased used to only say "cmd is
aliased to ...". Now it shows that to the standard error stream
and runs "git $cmd --help" where $cmd is the first word of the
alias expansion.
This could be misleading for those who alias a command with options
(e.g. with "[alias] cpn = cherry-pick -n", "git cpn --help" would
show the manual of "cherry-pick", and the reader would not be told
to pay close attention to the part that describes the "--no-commit"
option until closing the pager that showed the contents of the
manual, if the pager is configured to restore the original screen,
or would not be told at all, if the pager simply makes the message

Initialize archivers as soon as possible when running git-archive.
Various non-obvious behavior depends on having the archivers
initialized, such as determining the desired archival format from the
provided filename.
Since 08716b3c11 ("archive: refactor file extension format-guessing",
2011-06-21), archive_format_from_filename() has used the registered
archivers to match filenames (provided via --output) to archival
formats. However, when git-archive is executed with --remote, format
detection happens before the archivers have been registered. This causes
archives from remotes to always be generated as TAR files, regardless of
the actual filename (unless an explicit --format is provided).
This patch fixes that behavior; archival format is determined properly
from the output filename, even when --remote is used.

`git repack` can drop unreachable commits without further warning,
making the corresponding entries in `.git/shallow` invalid, which causes
serious problems when deepening the branches.
One scenario where unreachable commits are dropped by `git repack` is
when a `git fetch --prune` (or even a `git fetch` when a ref was
force-pushed in the meantime) can make a commit unreachable that was
reachable before.
Therefore it is not safe to assume that a `git repack -adlf` will keep
unreachable commits alone (under the assumption that they had not been
packed in the first place, which is an assumption at least some of Git's
code seems to make).
This is particularly important to keep in mind when looking at the
`.git/shallow` file: if any commits listed in that file become
unreachable, it is not a problem, but if they go missing, it *is* a
problem. One symptom of this problem is that a deepening fetch may now
fail with
fatal: error in object: unshallow <commit-hash>
To avoid this problem, let's prune the shallow list in `git repack` when
the `-d` option is passed, unless `-A` is passed, too (which would force
the now-unreachable objects to be turned into loose objects instead of
being deleted). Additionally, we also need to take `--keep-reachable`
and `--unpack-unreachable=<date>` into account.
Note: an alternative solution discussed during the review of this patch
was to teach `git fetch` to simply ignore entries in .git/shallow if the
corresponding commits do not exist locally. A quick test, however,
revealed that the .git/shallow file is written during a shallow *clone*,
in which case the commits do not exist, either, but the "shallow" line
*does* need to be sent. Therefore, this approach would be a lot more
finicky than the approach presented by the this patch.

The `prune_shallow()` function wants a full reachability check to be
completed before it goes to work, to ensure that all unreachable entries
are removed from the shallow file.
However, in the upcoming patch we do not even want to go that far. We
really only need to remove entries corresponding to pruned commits, i.e.
to commits that no longer exist.
Let's support that use case.
Rather than extending the signature of `prune_shallow()` to accept
another Boolean, let's turn it into a bit field and declare constants,
for readability.

Since we cannot stash dirty submodules, there is no use in requiring

This brings the built-in rebase in line with the previous, scripted

admittedly not very easy to figure that out).

When git reset is run with the --quiet flag, don't bother finding any
additional unstaged changes as they won't be output anyway. This speeds up
the git reset command by avoiding having to lstat() every file looking for
changes that aren't going to be reported anyway.
The savings can be significant. In a repo on Windows with 200K files
"git reset" drops from 7.16 seconds to 0.32 seconds for a savings of 96%.
