fetch-pack: don't try to fetch peel values with --all
When "fetch-pack --all" sees a tag-to-blob on the remote, it
tries to fetch both the tag itself ("refs/tags/foo") and the
peeled value that the remote advertises ("refs/tags/foo^{}").
Asking for the object pointed to by the latter can cause
upload-pack to complain with "not our ref", since it does
not mark the peeled objects with the OUR_REF (unless they
were at the tip of some other ref).
Arguably upload-pack _should_ be marking those peeled
objects. But it never has in the past, since clients would
generally just ask for the tag and expect to get the peeled
value along with it. And that's how "git fetch" works, as
well as older versions of "fetch-pack --all".
The problem was introduced by 5f0fc64513 (fetch-pack:
eliminate spurious error messages, 2012-09-09). Before then,
the matching logic was something like:
if (refname is ill-formed)
do nothing
else if (doing --all)
always consider it matched
else
look through list of sought refs for a match
That commit wanted to flip the order of the second two arms
of that conditional. But we ended up with:
if (refname is ill-formed)
do nothing
else
look through list of sought refs for a match
if (--all and no match so far)
always consider it matched
That means tha an ill-formed ref will trigger the --all
conditional block, even though we should just be ignoring
it. We can fix that by having a single "else" with all of
the well-formed logic, that checks the sought refs and
"--all" in the correct order.

Commit 159e7b080b (fsck: detect gitmodules files,
2018-05-02) taught fsck to look at the content of
.gitmodules files. If the object turns out not to be a blob
at all, we just complain and punt on checking the content.
And since this was such an obvious and trivial code path, I
didn't even bother to add a test.
Except it _does_ do one non-trivial thing, which is call the
report() function, which wants us to pass a pointer to a
"struct object". Which we don't have (we have only a "struct
object_id"). So we erroneously pass a NULL object to
report(), which gets dereferenced and causes a segfault.
It seems like we could refactor report() to just take the
object_id itself. But we pass the object pointer along to
a callback function, and indeed this ends up in
builtin/fsck.c's objreport() which does want to look at
other parts of the object (like the type).
So instead, let's just use lookup_unknown_object() to get
the real "struct object", and pass that.

t7415: don't bother creating commit for symlink test
Early versions of the fsck .gitmodules detection code

though, finds a .gitmodules file in _any_ tree (see that
commit for more discussion).
As a result, there's no need to create a commit in our
tests. Let's drop it in the name of simplicity. And since
that was the only thing referencing $tree, we can pull our
tree creation out of a command substitution.

The commands that make use of --git-completion-helper feature could
now produce a lot of --no-xxx options that a command can take. This in
many case could nearly double the amount of completable options, using
more screen estate and also harder to search for the wanted option.
This patch attempts to mitigate that by collapsing extra --no-
options, the ones that are added by --git-completion-helper and not in
original struct option arrays. The "--no-..." option will be displayed
in this case to hint about more options, e.g.
Corner case: to make sure that people will never accidentally complete
the fake option "--no-..." there must be one real --no- in the first
complete listing even if it's not from the original struct option.

"--no-*" block and share the code but ";&" is not available on bash-3

tests: make forging GPG signed commits and tags more robust
A couple of test scripts create forged GPG signed commits or tags to
check that such forgery can't fool various git commands' signature
verification. All but one of those test scripts are prone to
occasional failures because the forgery creates a bogus GPG signature,
and git commands error out with an unexpected error message, e.g.
"Commit deadbeef does not have a GPG signature" instead of "... has a
bad GPG signature".
't5573-pull-verify-signatures.sh', 't7510-signed-commit.sh' and
't7612-merge-verify-signatures.sh' create forged signed commits like
this:
git commit -S -m "bad on side" &&
git cat-file commit side-bad >raw &&
sed -e "s/bad/forged bad/" raw >forged &&
git hash-object -w -t commit forged >forged.commit
On rare occasions the given pattern occurs not only in the commit
message but in the GPG signature as well, and after it's replaced in
the signature the resulting signature becomes invalid, GPG will report
CRC error and that it couldn't find any signature, which will then
ultimately cause the test failure.
Since in all three cases the pattern to be replaced during the forgery
is the first word of the commit message's subject line, and since the
GPG signature in the commit object is indented by a space, let's just
anchor those patterns to the beginning of the line to prevent this
issue.
The test script 't7030-verify-tag.sh' creates a forged signed tag
object in a similar way by replacing the pattern "seventh", but the
GPG signature in tag objects is not indented by a space, so the above
solution is not applicable in this case. However, in the tag object
in question the pattern "seventh" occurs not only in the tag message
but in the 'tag' header as well. To create a forged tag object it's
sufficient to replace only one of the two occurences, so modify the
sed script to limit the pattern to the 'tag' header (i.e. a line
beginning with "tag ", which, because of the space character, can
never occur in the base64-encoded GPG signature).
Note that the forgery in 't7004-tag.sh' is not affected by this issue:
while 't7004' does create a forged signed tag kind of the same way,
it replaces "signed-tag" in the tag object, which, because of the '-'
character, can never occur in the base64-encoded GPG signarute.

refspec: initalize `refspec_item` in `valid_fetch_refspec()`
We allocate a `struct refspec_item` on the stack without initializing
it. In particular, its `dst` and `src` members will contain some random
data from the stack. When we later call `refspec_item_clear()`, it will
call `free()` on those pointers. So if the call to `parse_refspec()` did
not assign to them, we will be freeing some random "pointers". This is
undefined behavior.
To the best of my understanding, this cannot currently be triggered by
user-provided data. And for what it's worth, the test-suite does not
trigger this with SANITIZE=address. It can be provoked by calling
`valid_fetch_refspec(":*")`.
Zero the struct, as is done in other users of `struct refspec_item` by
using the refspec_item_init() initialization function.

add -p: fix counting empty context lines in edited patches
recount_edited_hunk() introduced in commit 2b8ea7f3c7 ("add -p:

context lines to start with a space, empty lines are not counted. This
was intended to avoid any recounting problems if the user had
introduced empty lines at the end when editing the patch. However this
introduced a regression into 'git add -p' as it seems it is common for
editors to strip the trailing whitespace from empty context lines when
patches are edited thereby introducing empty lines that should be
counted. 'git apply' knows how to deal with such empty lines and POSIX
states that whether or not there is an space on an empty context line
is implementation defined [1].
Fix the regression by counting lines that consist solely of a newline
as well as lines starting with a space as context lines and add a test
to prevent future regressions.

upload-pack: reject shallow requests that would return nothing
Shallow clones with --shallow-since or --shalow-exclude work by
running rev-list to get all reachable commits, then draw a boundary
between reachable and unreachable and send "shallow" requests based on
that.
The code does miss one corner case: if rev-list returns nothing, we'll
have no border and we'll send no shallow requests back to the client
(i.e. no history cuts). This essentially means a full clone (or a full
branch if the client requests just one branch). One example is the
oldest commit is older than what is specified by --shallow-since.
To avoid this, if rev-list returns nothing, we abort the clone/fetch.
The user could adjust their request (e.g. --shallow-since further back
in the past) and retry.
Another possible option for this case is to fall back to a default
depth (like depth 1). But I don't like too much magic that way because
we may return something unexpected to the user. If they request
"history since 2008" and we return a single depth at 2000, that might
break stuff for them. It is better to tell them that something is
wrong and let them take the best course of action.
Note that we need to die() in get_shallow_commits_by_rev_list()
instead of just checking for empty result from its caller
deepen_by_rev_list() and handling the error there. The reason is,
empty result could be a valid case: if you have commits in year 2013
and you request --shallow-since=year.2000 then you should get a full
clone (i.e. empty result).

fetch: do not pass ref-prefixes for fetch by exact SHA1
When v2.18.0-rc0~10^2~1 (refspec: consolidate ref-prefix generation
logic, 2018-05-16) factored out the ref-prefix generation code for
reuse, it left out the 'if (!item->exact_sha1)' test in the original
ref-prefix generation code. As a result, fetches by SHA-1 generate
ref-prefixes as though the SHA-1 being fetched were an abbreviated ref
name:
If there is another ref name on the command line or the object being
fetched is already available locally, then that's mostly harmless.
But otherwise, we error out with
fatal: no matching remote head
since the server did not send any refs we are interested in. Filter
out the exact_sha1 refspecs to avoid this.

index-pack: handle --strict checks of non-repo packs
Commit 73c3f0f704 (index-pack: check .gitmodules files with
--strict, 2018-05-04) added a call to add_packed_git(), with
the intent that the newly-indexed objects would be available
to the process when we run fsck_finish(). But that's not
what add_packed_git() does. It only allocates the struct,
and you must install_packed_git() on the result. So that
call was effectively doing nothing (except leaking a
struct).
But wait, we passed all of the tests! Does that mean we
don't need the call at all?
For normal cases, no. When we run "index-pack --stdin"
inside a repository, we write the new pack into the object
directory. If fsck_finish() needs to access one of the new
objects, then our initial lookup will fail to find it, but
we'll follow up by running reprepare_packed_git() and
looking again. That logic was meant to handle somebody else
repacking simultaneously, but it ends up working for us
here.
But there is a case that does need this, that we were not
testing. You can run "git index-pack foo.pack" on any file,
even when it is not inside the object directory. Or you may
not even be in a repository at all! This case fails without
doing the proper install_packed_git() call.
We can make this work by adding the install call.
Note that we should be prepared to handle add_packed_git()
failing. We can just silently ignore this case, though. If
fsck_finish() later needs the objects and they're not
available, it will complain itself. And if it doesn't
(because we were able to resolve the whole fsck in the first
pass), then it actually isn't an interesting error at all.

prepare_commit_graft: treat non-repository as a noop
The parse_commit_buffer() function consults lookup_commit_graft()
to see if we need to rewrite parents. The latter will look
at $GIT_DIR/info/grafts. If you're outside of a repository,
then this will trigger a BUG() as of b1ef400eec (setup_git_env:
avoid blind fall-back to ".git", 2016-10-20).
It's probably uncommon to actually parse a commit outside of
a repository, but you can see it in action with:
cd /not/a/git/repo
git index-pack --strict /some/file.pack
This works fine without --strict, but the fsck checks will
try to parse any commits, triggering the BUG(). We can fix
that by teaching the graft code to behave as if there are no
grafts when we aren't in a repository.
Arguably index-pack (and fsck) are wrong to consider grafts
at all. So another solution is to disable grafts entirely
for those commands. But given that the graft feature is
deprecated anyway, it's not worth even thinking through the
ramifications that might have.
There is one other corner case I considered here. What
should:
cd /not/a/git/repo
export GIT_GRAFT_FILE=/file/with/grafts
git index-pack --strict /some/file.pack
do? We don't have a repository, but the user has pointed us
directly at a graft file, which we could respect. I believe
this case did work that way prior to b1ef400eec. However,
fixing it now would be pretty invasive. Back then we would
just call into setup_git_env() even without a repository.
But these days it actually takes a git_dir argument. So
there would be a fair bit of refactoring of the setup code
involved.
Given the obscurity of this case, plus the fact that grafts
are deprecated and probably shouldn't work under index-pack
anyway, it's not worth pursuing further. This patch at least
un-breaks the common case where you're _not_ using grafts,
but we BUG() anyway trying to even find that out.

rebase: use the new git-rebase--preserve-merges.sh
Create a new type of rebase, "preserve-merges", used when rebase is

Before that, the type for preserve-merges was "interactive", and some

"explicit" when calling an interactive rebase (and, possibly, one of its
submodes), and "implied" when calling one of its
submodes (eg. preserve-merges) *without* interactive rebase.
It also detects the presence of the directory "$merge_dir"/rewritten
left by the preserve-merges script when calling rebase --continue,
--skip, etc., and, if it exists, sets the rebase mode to
preserve-merges. In this case, interactive_rebase is set to "explicit",

...
"git blame" learns to unhighlight uninteresting metadata from the
originating commit on lines that are the same as the previous one,
and also paint lines in different colors depending on the age of
the commit.
* sb/blame-color:
builtin/blame: add new coloring scheme config
builtin/blame: highlight recently changed lines
builtin/blame: dim uninteresting metadata lines
"git submodule update" and "git submodule add" supported the
"--reference" option to borrow objects from a neighbouring local
repository like "git clone" does, but lacked the more recent
invention "--dissociate". Also "git submodule add" has been taught
to take the "--progress" option.
* cf/submodule-progress-dissociate:
submodule: add --dissociate option to add/update commands
submodule: add --progress option to add command
submodule: clean up substitutions in script
Command line completion (in contrib/) learned to complete pathnames
for various commands better.
* sg/complete-paths:
t9902-completion: exercise __git_complete_index_file() directly
completion: don't return with error from __gitcomp_file_direct()
completion: fill COMPREPLY directly when completing paths
completion: improve handling quoted paths in 'git ls-files's output
completion: remove repeated dirnames with 'awk' during path completion
t9902-completion: ignore COMPREPLY element order in some tests
completion: use 'awk' to strip trailing path components
completion: let 'ls-files' and 'diff-index' filter matching paths
completion: improve handling quoted paths on the command line
completion: support completing non-ASCII pathnames
completion: simplify prefix path component handling during path completion
completion: move __git_complete_index_file() next to its helpers
t9902-completion: add tests demonstrating issues with quoted pathnames
"git update-ref A B" is supposed to ensure that ref A does not yet
exist when B is a NULL OID, but this check was not done correctly
for pseudo-refs outside refs/ hierarchy, e.g. MERGE_HEAD.
* ma/create-pseudoref-with-null-old-oid:
refs: handle zero oid for pseudorefs
t1400: add tests around adding/deleting pseudorefs
refs.c: refer to "object ID", not "sha1", in error messages
Code clean-up to turn history traversal more robust in a
semi-corrupt repository.
* jk/unavailable-can-be-missing:
mark_parents_uninteresting(): avoid most allocation
mark_parents_uninteresting(): replace list with stack
mark_parents_uninteresting(): drop missing object check
mark_tree_contents_uninteresting(): drop missing object check
"git status" learned to honor a new status.renames configuration to
skip rename detection, which could be useful for those who want to
do so without disabling the default rename detection done by the
"git diff" command.
* bp/status-rename-config:
add status config and command line options for rename detection
Developer support update, by using BUG() macro instead of die() to
mark codepaths that should not happen more clearly.
* js/use-bug-macro:
BUG_exit_code: fix sparse "symbol not declared" warning
Convert remaining die*(BUG) messages
Replace all die("BUG: ...") calls by BUG() ones
run-command: use BUG() to report bugs, not die()
test-tool: help verifying BUG() code paths
Code clean-up to adjust to a more recent lockfile API convention that
allows lockfile instances kept on the stack.
* ma/lockfile-cleanup:
lock_file: move static locks into functions
lock_file: make function-local locks non-static
refs.c: do not die if locking fails in `delete_pseudoref()`
refs.c: do not die if locking fails in `write_pseudoref()`
t/helper/test-write-cache: clean up lock-handling
With merge.renames configuration set to false, the recursive merge
strategy can be told not to spend cycles trying to find renamed
paths and merge them accordingly.
* bp/merge-rename-config:
merge: pass aggressive when rename detection is turned off
merge: add merge.renames config setting
merge: update documentation for {merge,diff}.renameLimit
The implementation of "git rebase -i --root" has been updated to use
the sequencer machinery more.
* js/sequencer-and-root-commits:
rebase --rebase-merges: root commits can be cousins, too
rebase --rebase-merges: a "merge" into a new root is a fast-forward
sequencer: allow introducing new root commits
rebase -i --root: let the sequencer handle even the initial part
sequencer: learn about the special "fake root commit" handling
sequencer: extract helper to update active_cache_tree
"git send-email" can sometimes offer confirmation dialog "Send this
email?" with choices 'Yes', 'No', 'Quit', and 'All'. A new action
'Edit' has been added to this dialog's choice.
* dd/send-email-reedit:
git-send-email: allow re-editing of message
