v2.18.0-rc0~90^2 (completion: reduce overhead of clearing cached
--options, 2018-04-18) worked around a bug in bash's "set" builtin on
MacOS by using compgen instead. It was careful to avoid breaking zsh
by guarding this workaround with
if [[ -n ${ZSH_VERSION-}} ]]
Alas, this interacts poorly with git-completion.zsh's bash emulation:
ZSH_VERSION='' . "$script"
Correct it by instead using a new GIT_SOURCING_ZSH_COMPLETION shell
variable to detect whether git-completion.bash is being sourced from
git-completion.zsh. This way, the zsh variant is used both when run
from zsh directly and when run via git-completion.zsh.
Reproduction recipe:
1. cd git/contrib/completion && cp git-completion.zsh _git
2. Put the following in a new ~/.zshrc file:
autoload -U compinit; compinit
autoload -U bashcompinit; bashcompinit
fpath=(~/src/git/contrib/completion $fpath)
3. Open zsh and "git <TAB>".
With this patch:
Triggers nice git-completion.bash based tab completion
Without:
contrib/completion/git-completion.bash:354: read-only variable: QISUFFIX
zsh:12: command not found: ___main

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.

Early versions of the fsck .gitmodules detection code
actually required a tree to be at the root of a commit for
it to be checked for .gitmodules. What we ended up with in
159e7b080b (fsck: detect gitmodules files, 2018-05-02),
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.
> ~/w/git $ git clone --
--bare --origin=
--branch= --progress
--checkout --quiet
--config= --recurse-submodules
--depth= --reference=
--dissociate --reference-if-able=
--filter= --separate-git-dir=
--hardlinks --shallow-exclude=
--ipv4 --shallow-since=
--ipv6 --shallow-submodules
--jobs= --shared
--local --single-branch
--mirror --tags
--no-... --template=
--no-checkout --upload-pack=
--no-hardlinks --verbose
--no-tags
and when you complete it with --no-<tab>, all negative options will be
presented:
> ~/w/git $ git clone --no-
--no-bare --no-quiet
--no-branch --no-recurse-submodules
--no-checkout --no-reference
--no-config --no-reference-if-able
--no-depth --no-separate-git-dir
--no-dissociate --no-shallow-exclude
--no-filter --no-shallow-since
--no-hardlinks --no-shallow-submodules
--no-ipv4 --no-shared
--no-ipv6 --no-single-branch
--no-jobs --no-tags
--no-local --no-template
--no-mirror --no-upload-pack
--no-origin --no-verbose
--no-progress
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.
PS. This could could be made simpler with ";&" to fall through from
"--no-*" block and share the code but ";&" is not available on bash-3

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.

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.

recount_edited_hunk() introduced in commit 2b8ea7f3c7 ("add -p:
calculate offset delta for edited patches", 2018-03-05) required all
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.

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).

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:
$ GIT_TRACE_PACKET=1 bin-wrappers/git -c protocol.version=2 \
fetch origin 12039e008f
[...]
packet: fetch> ref-prefix 12039e008f

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.

behavior difference between protocol v0 and v2 in the process. Add a
