CMake adjustments for recent changes around unit tests.
* jc/cmake-unit-test-updates:
cmake: generalize the handling of the `UNIT_TEST_OBJS` list
cmake: stop looking for `REFTABLE_TEST_OBJS` in the Makefile
cmake: rename clar-related variables to avoid confusion
A few usability fixes to "git jump" (in contrib/).
* jk/jump-quickfix-fixes:
git-jump: ignore deleted files in diff mode
git-jump: always specify column 1 for diff entries
In a15d4465a9 (cmake: also build unit tests, 2023-09-25), I
accommodated the CMake definition. Seeing that a `UNIT_TEST_OBJS` list
was introduced that was built by transforming the `UNIT_TEST_PROGRAMS`
list and then adding a single, hard-coded file
("t/unit-tests/test-lib.c"), I decided to hard-code that in the CMake
definition, too.
The reason why I hard-coded it instead of imitating the
`parse_makefile_for_sources()` paradigm that was used elsewhere when
using the `Makefile` as source of truth for given lists of files: This
function expects _only_ hard-coded values, and that transformed
`UNIT_TEST_PROGRAMS` list complicated everything.
In 872721538c (cmake: fix build of `t-oidtree`, 2024-07-12), I
accommodated the CMake definition again, after seeing that the
`UNIT_TEST_OBJS` was still defined via that transformed list but now
appending _two_ hard-coded files ("t/unit-tests/lib-oid.c" joined the
fray).
In 428672a3b1 (Makefile: stop listing test library objects twice,
2024-09-16), the `Makefile` was changed so that `UNIT_TEST_OBJS` is
finally only constructed using hard-coded file names just like the other
`*_OBJS` variables. I missed that and therefore did not adjust the CMake
definition. Besides, the code was working, so there was no real need to
adjust it.
With a4f50bb1e9 (t/unit-tests: introduce reftable library, 2024-09-16),
however, the `UNIT_TEST_OBJS` list became a trio, and the CMake
definition has to be adjusted again. Now that we can use the
`parse_makefile_for_sources()` function without many complications,
let's do that.

If you do something like this:
rm file_a
echo change >file_b
git jump diff
then we'll generate two quickfix entries for the diff, one for each
file. But the one for the deleted file is rather pointless. There's no
content to show since the file is gone, and in fact we open the editor
with the path /dev/null!
In vim, at least, the result is a confusing annoyance: the editor opens
with an empty buffer, and you have to skip past it to the useful
quickfix entry (after scratching your head and figuring out that no,
nothing is broken).
Let's skip such entries entirely. There's nothing useful to show, since
the point is that the file has been deleted.
It is possible that you could be doing a diff whose post-image is not
the working tree, and then you'd perhaps be jumping to the deleted
content (or at least something that was in the same spot). But I don't
think it's worth worrying about that case. For one thing, using git-jump
for such diffs is a bad idea in general, as it's going to sometimes move
you to the wrong spot. And two, a deletion is always going to have one
hunk starting at line 1, which is not that interesting to jump to in the
first place.

When we generate a quickfix entry for a diff hunk, we provide just the
filename and line number along with the content, like:
file:1: contents of the line
This can be a problem if the line itself looks like a quickfix header.
For example (and this is adapted from a real-world case that bit me):
echo 'static_lease 10:11:12:13:14:15:16 10.0.0.1' >file
git add file
echo change >file
produces:
file:1: static_lease 10:11:12:13:14:15:16 10.0.0.1
which is ambiguous. It could be line 1 of "file", or line 11 of the file
"file:1: static_lease 10", and so on. In the case of vim's default
config, it seems to prefer the latter (you can configure "errorformat"
with a variety of patterns, but out of the box it matches some common
ones).
One easy way to fix this is to provide a column number, like:
file:1:1: static_lease 10:11:12:13:14:15:16 10.0.0.1
which causes vim to prefer line 1 of "file" again (due to the preference
order of the various patterns in the default errorformat).
There are other options. For example, at least in my version of vim,
wrapping the file in quotation marks like:
"file":1: static_lease 10:11:12:13:14:15:16 10.0.0.1
also works. That perhaps would the right thing even if you had the silly
file name "file:1:1: foo 10". But it's not clear what would happen if
you had a filename with quotes in it.
This feature is inherently scraping text, and there's bound to be some
ambiguities. I don't think it's worth worrying too much about unlikely
filenames, as its the file content that is more likely to introduce
unexpected characters.
So let's just go with the extra ":1" column specifier. We know this is
supported everywhere, as git-jump's "grep" mode already uses it (and
thus doesn't exhibit the same problem).
The "merge" mode is mostly immune to this, as it only matches "<<<<<<<"
conflict marker lines. It's possible of course to have a marker that
says "foo 10:11" later in the line, but in practice these will only have
branches and perhaps file names, so it's probably not worth worrying
about (and fixing it would involve passing --column to the system grep,
which may not be portable).
I also gave some thought as to whether we could put something more
useful than "1" in the column field for diffs. In theory we could find
the first changed character of the line, but this is tricky in practice.
You'd have to correlate before/after lines of the hunk to decide what
changed. So:
-this is a foo line
+this is a bar line
is easy (column 11). But:
-this is a foo line
+another line
+this is a bar line
is harder.
This commit certainly doesn't preclude trying to do something more
clever later, but it's a much deeper rabbit hole than just fixing the
syntactic ambiguity.

The command line prompt support used to be littered with bash-isms,
which has been corrected to work with more shells.
* ah/git-prompt-portability:
git-prompt: support custom 0-width PS1 markers
git-prompt: ta-da! document usage in other shells
git-prompt: don't use shell $'...'
git-prompt: add some missing quotes
git-prompt: replace [[...]] with standard code
git-prompt: don't use shell arrays
git-prompt: fix uninitialized variable
git-prompt: use here-doc instead of here-string
When using colors, the shell needs to identify 0-width substrings
in PS1 - such as color escape sequences - when calculating the
on-screen width of the prompt.
Until now, we used the form %F{<color>} in zsh - which it knows is
0-width, or otherwise use standard SGR esc sequences wrapped between
byte values 1 and 2 (SOH, STX) as 0-width start/end markers, which
bash/readline identify as such.
But now that more shells are supported, the standard SGR sequences
typically work, but the SOH/STX markers might not be identified.
This commit adds support for vars GIT_PS1_COLOR_{PRE,POST} which
set custom 0-width markers or disable the markers.

With one big exception, git-prompt.sh should now be both almost posix
compliant, and also compatible with most (posix-ish) shells.
That exception is the use of "local" vars in functions, which happens
extensively in the current code, and is not simple to replace with
posix compliant code (but also not impossible).
Luckily, almost all shells support "local" as used by the current
code, with the notable exception of ksh93[u+m], but also the Schily
minimal posix sh (pbosh), and yash in posix mode.
See assessment below that "local" is likely the only blocker in those.
So except mainly ksh93, git-prompt.sh now works in most shells:
- bash, zsh, dash since at least 0.5.8, free/net bsd sh, busybox-ash,
mksh, openbsd sh, pdksh(!), Schily extended Bourne sh (bosh), yash.
which is quite nice.
As an anecdote, replacing the 1st line in __git_ps1() (local exit=$?)
with these 2 makes it work in all tested shells, even without "local":
# handles only 0/1 args for simplicity. needs +5 LOC for any $#
__git_e=$?; local exit="$__git_e" 2>/dev/null ||
{(eval 'local() { export "$@"; }'; __git_ps1 "$@"); return "$__git_e"; }
Explanation:
If the shell doesn't have the command "local", define our own
function "local" which instead does plain (global) assignents.
Then use __git_ps1 in a subshell to not clober the caller's vars.
This happens to work because currently there are no name conflicts
(shadow) at the code, initial value is not assumed (i.e. always
doing either 'local x=...' or 'local x;... x=...'), and assigned
initial values are quoted (local x="$y"), preventing word split and
glob expansion (i.e. assignment context is not assumed).
The last two (always init, quote values) seem to be enough to use
"local" portably if supported, and otherwise shells indeed differ.
Uses "eval", else shells with "local" may reject it during parsing.
We don't need "export", but it's smaller than writing our own loop.
While cute, this approach is not really sustainable because all the
vars become global, which is hard to maintain without conflicts
(but hey, it currently has no conflicts - without even trying...).
However, regardless of being an anecdote, it provides some support to
the assessment that "local" is the only blocker in those shells.

$'...' is new in POSIX (2024), and some shells support it in recent
versions, while others have had it for decades (bash, zsh, ksh93).
However, there are still enough shells which don't support it, and
it's cheap to use an alternative form which works in all shells,
so let's do that instead of dismissing it as "it's compliant".
It was agreed to use one form rather than $'...' where supported and
fallback otherwise.
shells where $'...' works:
- bash, zsh, ksh93, mksh, busybox-ash, dash master, free/net bsd sh.
shells where it doesn't work, but the new fallback works:
- all dash releases (up to 0.5.12), older versions of free/net bsd sh,
openbsd sh, pdksh, all Schily Bourne sh variants, yash.

The issues which this commit fixes are unlikely to be broken
in real life, but the fixes improve correctness, and would prevent
bugs in some uncommon cases, such as weird IFS values.
Listing some portability guidelines here for future reference.
I'm leaving it to someone else to decide whether to include
it in the file itself, place it as a new file, or not.
---------
The command "local" is non standard, but is allowed in this file:
- Quote initialization if it can expand (local x="$y"). See below.
- Don't assume initial value after "local x". Either initialize it
(local x=..), or set before first use (local x;.. x=..; <use $x>).
(between shells, "local x" can unset x, or inherit it, or do x= )
Other non-standard features beyond "local" are to be avoided.
Use the standard "test" - [...] instead of non-standard [[...]] .
--------
Quotes (some portability things, but mainly general correctness):
Quotes prevent tilde-expansion of some unquoted literal tildes (~).
If the expansion is undesirable, quotes would ensure that.
Tilds expanded: a=~user:~/ ; echo ~user ~/dir
not expanded: t="~"; a=${t}user b=\~foo~; echo "~user" $t/dir
But the main reason for quoting is to prevent IFS field splitting
(which also coalesces IFS chars) and glob expansion in parts which
contain parameter/arithmetic expansion or command substitution.
"Simple command" (POSIX term) is assignment[s] and/or command [args].
Examples:
foo=bar # one assignment
foo=$bar x=y # two assignments
foo bar # command, no assignments
x=123 foo bar # one assignment and a command
The assignments part is not IFS-split or glob-expanded.
The command+args part does get IFS field split and glob expanded,
but only at unquoted expanded/substituted parts.
In the command+args part, expanded/substituted values must be quoted.
(the commands here are "[" and "local"):
Good: [ "$mode" = yes ]; local s="*" x="$y" e="$?" z="$(cmd ...)"
Bad: [ $mode = yes ]; local s=* x=$y e=$? z=$(cmd...)
The arguments to "local" do look like assignments, but they're not
the assignment part of a simple command; they're at the command part.
Still at the command part, no need to quote non-expandable values:
Good: local x= y=yes; echo OK
OK, but not required: local x="" y="yes"; echo "OK"
But completely empty (NULL) arguments must be quoted:
foo "" is not the same as: foo
Assignments in simple commands - with or without an actual command,
don't need quoting becase there's no IFS split or glob expansion:
Good: s=* a=$b c=$(cmd...)${x# foo }${y- } [cmd ...]
It's also OK to use double quotes, but not required.
This behavior (no IFS/glob) is called "assignment context", and
"local" does not behave with assignment context in some shells,
hence we require quotes when using "local" - for compatibility.
The value between 'case' and 'in' doesn't IFS-split/glob-expand:
Good: case * $foo $(cmd...) in ... ; esac
identical: case "* $foo $(cmd...)" in ... ; esac
Nested quotes in command substitution are fine, often necessary:
Good: echo "$(foo... "$x" "$(bar ...)")"
Nested quotes in substring ops are legal, and sometimes needed
to prevent interpretation as a pattern, but not the most readable:
Legal: foo "${x#*"$y" }"
Nested quotes in "maybe other value" subst are invalid, unnecessary:
Good: local x="${y- }"; foo "${z:+ $a }"
Bad: local x="${y-" "}"; foo "${z:+" $a "}"
Outer/inner quotes in "maybe other value" have different use cases:
"${x-$y}" always one quoted arg: "$x" if x is set, else "$y".
${x+"$x"} one quoted arg "$x" if x is set, else no arg at all.
Unquoted $x is similar to the second case, but it would get split
into few arguments if it includes any of the IFS chars.
Assignments don't need the outer quotes, and the braces delimit the
value, so nested quotes can be avoided, for readability:
a=$(foo "$x") a=${x#*"$y" } c=${y- }; bar "$a" "$b" "$c"

The existing [[...]] tests were either already valid as standard [...]
tests, or only required minimal retouch:
Notes:
- [[...]] doesn't do field splitting and glob expansion, so $var
or $(cmd...) don't need quoting, but [... does need quotes.
- [[ X == Y ]] when Y is a string is same as [ X = Y ], but if Y is
a pattern, then we need: case X in Y)... ; esac .
- [[ ... && ... ]] was replaced with [ ... ] && [ ... ] .
- [[ -o <zsh-option> ]] requires [[...]], so put it in "eval" and only
eval it in zsh, so other shells would not abort on syntax error
(posix says [[ has unspecified results, shells allowed to reject it)
- ((x++)) was changed into x=$((x+1)) (yeah, not [[...]] ...)

Arrays only existed in the svn-upstream code, used to:
- Keep a list of svn remotes.
- Convert commit msg to array of words, extract the 2nd-to-last word.
Except bash/zsh, nearly all shells failed load on syntax errors here.
Now:
- The svn remotes are a list of newline-terminated values.
- The 2nd-to-last word is extracted using standard shell substrings.
- All shells can digest the svn-upstream code.
While using shell field splitting to extract the word is simple, and
doesn't even need non-standard code, e.g. set -- $(git log -1 ...),
it would have the same issues as the old array code: it depends on IFS
which we don't control, and it's subject to glob-expansion, e.g. if
the message happens to include * or **/* (as this commit message just
did), then the array could get huge. This was not great.
Now it uses standard shell substrings, and we know the exact delimiter
to expect, because it's the match from our grep just one line earlier.
The new word extraction code also fixes svn-upstream in zsh, because
previously it used arr[len-2], but because in zsh, unlike bash, array
subscripts are 1-based, it incorrectly extracted the 3rd-to-last word.
symptom: missing upstream status in a git-svn repo: u=, u+N-M, etc.
The breakage in zsh is surprising, because it was last touched by
commit d0583da838 (prompt: fix show upstream with svn and zsh),
claiming to fix exactly that. However, it only mentions syntax fixes.
It's unclear if behavior was fixed too. But it was broken, now fixed.
Note LF=$'\n' and then using $LF instead of $'\n' few times.
A future commit will add fallback for shells without $'...', so this
would be the only line to touch instead of replacing every $'\n' .
Shells which could run the previous array code:
- bash
Shells which have arrays but were broken anyway:
- zsh: 1-based subscript
- ksh93: no "local" (the new code can't fix this part...)
- mksh, openbsd sh, pdksh: failed load on syntax error: "for ((...))".

First use is in the form: local var; ...; var=$var$whatever...
If the variable was unset (as bash and others do after "local x"),
then it would error if set -u is in effect.
Also, many shells inherit the existing value after "local var"
without init, but in this case it's unlikely to have a prior value.

The credential helper to talk to OSX keychain sometimes sent
garbage bytes after the username, which has been corrected.
* jk/osxkeychain-username-is-nul-terminated:
credential/osxkeychain: respect NUL terminator in username
This patch fixes a case where git-credential-osxkeychain might output
uninitialized bytes to stdout.
We need to get the username string from a system API using
CFStringGetCString(). To do that, we get the max size for the string
from CFStringGetMaximumSizeForEncoding(), allocate a buffer based on
that, and then read into it. But then we print the entire buffer to
stdout, including the trailing NUL and any extra bytes which were not
needed. Instead, we should stop at the NUL.
This code comes from 9abe31f5f1 (osxkeychain: replace deprecated
SecKeychain API, 2024-02-17). The bug was probably overlooked back then
because this code is only used as a fallback when we can't get the
string via CFStringGetCStringPtr(). According to Apple's documentation:
Whether or not this function returns a valid pointer or NULL depends
on many factors, all of which depend on how the string was created and
its properties.
So it's not clear how we could make a test for this, and we'll have to
rely on manually testing on a system that triggered the bug in the first
place.

"git symbolic-ref" a bit better (you need to enable plumbing
commands to be completed with GIT_COMPLETION_SHOW_ALL_COMMANDS).
* rh/complete-symbolic-ref:
completion: add docs on how to add subcommand completions
completion: improve docs for using __git_complete
completion: add 'symbolic-ref'
Most of the functions in "refs.h" have two flavors: one that accepts a
`struct ref_store`, and one that figures it out via `the_repository`.
As part of the libification efforts we want to get rid of the latter
variant and stop relying on `the_repository` altogether.
Introduce a set of Coccinelle rules that transform callers of the "refs"
interfaces to pass a `struct ref_store`. These rules are not yet applied
by this patch so that it can be reviewed standalone more easily. This
will be done in the next patch.

The `test-tool` recently learned to run the unit tests. To this end, it
needs to link with `test-lib.c`, which was done in the `Makefile`, and
this patch does it in the CMake definition, too.
This is a companion of 44400f58407e (t0080: turn t-basic unit test into
a helper, 2024-02-02).

Completing commands like "git rebase" in one repository will leak the
local __git_repo_path into the shell's environment so that completing
commands after changing to a different repository will give the old
repository's references (or none at all).
The bug report on the mailing list [1] suggests one simple way to observe
this yourself:
Enter the following commands from some directory:
mkdir a b b/c
for d (a b); git -C $d init && git -C $d commit --allow-empty -m init
cd a
git branch foo
pushd ../b/c
git branch bar
Now type these:
git rebase <TAB>… # completion for bar available; C-c to abort
declare -p __git_repo_path # outputs /path/to/b/.git
popd
git branch # outputs foo, main
git rebase <TAB>… # completion candidates are bar, main!
Ideally, the last typed <TAB> should be yielding foo, main.
Commit beb6ee7163 (completion: extract repository discovery from
__gitdir(), 2017-02-03) anticipated this problem by marking
__git_repo_path as local in __git_main and __gitk_main for Bash
completion but did not give the same mark to _git for Zsh completion.
Thus make __git_repo_path local for Zsh completion, too.

It took me more than a few tries and a good lecture of __git_main to
understand that the two paragraphs really only refer to adding
completion functions for executables that are not called through git's
subcommand magic. Improve the docs and be more specific.

Even 'symbolic-ref' is only completed when
GIT_COMPLETION_SHOW_ALL_COMMANDS=1 is set, it currently defaults to
completing file names, which is not very helpful. Add a simple
completion function which completes options and refs.

Update osxkeychain backend with features required for the recent
credential subsystem.
* ba/osxkeychain-updates:
osxkeychain: store new attributes
osxkeychain: erase matching passwords only
osxkeychain: erase all matching credentials
osxkeychain: replace deprecated SecKeychain API
"git apply" has been updated to lift the hardcoded pathname length
limit, which in turn allowed a mksnpath() function that is no
longer used.
* rs/apply-lift-path-length-limit:
path: remove mksnpath()
apply: avoid fixed-size buffer in create_one_file()
Another "set -u" fix for the bash prompt (in contrib/) script.
* vs/complete-with-set-u-fix:
completion: protect prompt against unset SHOWUPSTREAM in nounset mode
completion: fix prompt with unset SHOWCONFLICTSTATE in nounset mode
d208bfdfef (credential: new attribute password_expiry_utc, 2023-02-18)
and a5c76569e7 (credential: new attribute oauth_refresh_token,
2023-04-21) introduced new credential attributes but support was missing
from git-credential-osxkeychain.
Support these attributes by appending the data to the password in the
keychain, separated by line breaks. Line breaks cannot appear in a git
credential password so it is an appropriate separator.
Fixes the remaining test failures with osxkeychain:
18 - helper (osxkeychain) gets password_expiry_utc
19 - helper (osxkeychain) overwrites when password_expiry_utc
changes
21 - helper (osxkeychain) gets oauth_refresh_token

Other credential helpers support deleting credentials that match a
specified password. See 7144dee3ec (credential/libsecret: erase matching
creds only, 2023-07-26) and cb626f8e5c (credential/wincred: erase
matching creds only, 2023-07-26).
Support this in osxkeychain too by extracting, decrypting and comparing
the stored password before deleting.
Fixes the following test failure with osxkeychain:
11 - helper (osxkeychain) does not erase a password distinct from
input

The SecKeychain API was deprecated in macOS 10.10, nearly 10 years ago.
The replacement SecItem API however is available as far back as macOS
10.6.
While supporting older macOS was perhaps prevously a concern,
git-credential-osxkeychain already requires a minimum of macOS 10.7
since 5747c8072b (contrib/credential: avoid fixed-size buffer in
osxkeychain, 2023-05-01) so using the newer API should not regress the
range of macOS versions supported.
Adapting to use the newer SecItem API also happens to fix two test
failures in osxkeychain:
8 - helper (osxkeychain) overwrites on store
9 - helper (osxkeychain) can forget host
The new API is compatible with credentials saved with the older API.

As it stands, the only call site of `__git_ps1_show_upstream` checks
that the `GIT_PS1_SHOWUPSTREAM` variable is set, so this is effectively
a no-op. However, that might change, and chances of noticing the
unprotected use might not be that high when it does.

contrib: drop hg-to-git script
The hg-to-git script is full of command injection vulnerabilities
against malicious branch and tag names. It's also old and largely
unmaintained; the last commit was over 4 years ago, and the last code
change before that was from 2013. Users are better off with a modern
remote-helper tool like cinnabar or remote-hg.
So rather than spending time to fix it, let's just get rid of it.
