Windows updates.

  git maintenance: avoid console window in scheduled tasks on Windows
  win32: add a helper to run `git.exe` without a foreground window

Johannes Schindelin 4b8a2717bb win32: add a helper to run `git.exe` without a foreground window
On Windows, there are two kinds of executables, console ones and
non-console ones. Git's executables are all console ones.

When launching the former e.g. in a scheduled task, a CMD window pops
up. This is not what we want for the tasks installed via the `git
maintenance` command.

To work around this, let's introduce `headless-git.exe`, which is a
non-console program that does _not_ pop up any window. All it does is to
re-launch `git.exe`, suppressing that console window, passing through
all command-line arguments as-are.

René Scharfe e8e5d294dc parse-options: show negatability of options in short help
Add a "[no-]" prefix to options without the flag PARSE_OPT_NONEG to
document the fact that you can negate them.

This looks a bit strange for options that already start with "no-", e.g.
for the option --no-name of git show-branch:

    --[no-]no-name        suppress naming strings

You can actually use --no-no-name as an alias of --name, so the short
help is not wrong.  If we strip off any of the "no-"s, we lose either
the ability to see if the remaining one belongs to the documented
variant or to see if it can be negated.

René Scharfe d716512870 subtree: disallow --no-{help,quiet,debug,branch,message}
"git subtree" only handles the negated variant of the options annotate,
prefix, onto, rejoin, ignore-joins and squash explicitly.  help is
handled by "git rev-parse --parseopt" implicitly, but not its negated
form.  Disable negation for it and the for the rest of the options to
get a helpful error message when trying them.

M Hickford cb626f8e5c credential/wincred: erase matching creds only
The credential erase request typically includes protocol, host, username
and password.

credential-wincred erases stored credentials that match protocol,
host and username, regardless of password.

This is confusing in the case the stored password differs from that
in the request. This case can occur when multiple credential helpers are
configured.

Only erase credential if stored password matches request (or request
omits password).

This fixes test "helper (wincred) does not erase a password distinct
from input" when t0303 is run with GIT_TEST_CREDENTIAL_HELPER set to
"wincred". This test was added in aeb21ce22e (credential: avoid
erasing distinct password, 2023-06-13).

Glen Choo 8868b1ebfb config: pass kvi to die_bad_number()
Plumb "struct key_value_info" through all code paths that end in
die_bad_number(), which lets us remove the helper functions that read
analogous values from "struct config_reader". As a result, nothing reads
config_reader.config_kvi any more, so remove that too.

In config.c, this requires changing the signature of
git_configset_get_value() to 'return' "kvi" in an out parameter so that
git_configset_get_<type>() can pass it to git_config_<type>(). Only
numeric types will use "kvi", so for non-numeric types (e.g.
git_configset_get_string()), pass NULL to indicate that the out
parameter isn't needed.

Outside of config.c, config callbacks now need to pass "ctx->kvi" to any
of the git_config_<type>() functions that parse a config string into a
number type. Included is a .cocci patch to make that refactor.

The only exceptional case is builtin/config.c, where git_config_<type>()
is called outside of a config callback (namely, on user-provided input),
so config source information has never been available. In this case,
die_bad_number() defaults to a generic, but perfectly descriptive
message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure
not to change the message.

Glen Choo a4e7e317f8 config: add ctx arg to config_fn_t
Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).

In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.

Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:

- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed

Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.

The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:

- trace2/tr2_cfg.c:tr2_cfg_set_fl()

  This is indirectly called by git_config_set() so that the trace2
  machinery can notice the new config values and update its settings
  using the tr2 config parsing function, i.e. tr2_cfg_cb().

- builtin/checkout.c:checkout_main()

  This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
  This might be worth refactoring away in the future, since
  git_xmerge_config() can call git_default_config(), which can do much
  more than just parsing.

Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

M Hickford 0ce02e2fec credential/libsecret: store new attributes
d208bfd (credential: new attribute password_expiry_utc, 2023-02-18)
and a5c76569e7 (credential: new attribute oauth_refresh_token)
introduced new credential attributes.

libsecret assumes attribute values are non-confidential and
unchanging, so we encode the new attributes in the secret, separated by
newline:

    hunter2
    password_expiry_utc=1684189401
    oauth_refresh_token=xyzzy

This is extensible and backwards compatible. The credential protocol
already assumes that attribute values do not contain newlines.

Alternatives considered: store password_expiry_utc in a libsecret
attribute. This has the problem that libsecret creates new items
rather than overwrites when attribute values change.

Taylor Blau 0a3a972c16 contrib/credential: embiggen fixed-size buffer in wincred
As in previous commits, harden the wincred credential helper against the
aforementioned protocol injection attack.

Unlike the approached used for osxkeychain and libsecret, where a
fixed-size buffer was replaced with `getline()`, we must take a
different approach here. There is no `getline()` equivalent in Windows,
and the function is not available to us with ordinary compiler settings.

Instead, allocate a larger (still fixed-size) buffer in which to process
each line. The value of 100 KiB is chosen to match the maximum-length
header that curl will allow, CURL_MAX_HTTP_HEADER.

To ensure that we are reading complete lines at a time, and that we
aren't susceptible to a similar injection attack (albeit with more
padding), ensure that each read terminates at a newline (i.e., that no
line is more than 100 KiB long).

Note that it isn't sufficient to turn the old loop into something like:

    while (len && strchr("\r\n", buf[len - 1])) {
      buf[--len] = 0;
      ends_in_newline = 1;
    }

because if an attacker sends something like:

    [aaaaa.....]\r
    host=example.com\r\n

the credential helper would fill its buffer after reading up through the
first '\r', call fgets() again, and then see "host=example.com\r\n" on
its line.

Note that the original code was written in a way that would trim an
arbitrary number of "\r" and "\n" from the end of the string. We should
get only a single "\n" (since the point of `fgets()` is to return the
buffer to us when it sees one), and likewise would not expect to see
more than one associated "\r". The new code trims a single "\r\n", which
matches the original intent.

Taylor Blau 64f1e658e9 contrib/credential: avoid fixed-size buffer in libsecret
The libsecret credential helper reads the newline-delimited
protocol stream one line at a time by repeatedly calling fgets() into a
fixed-size buffer, and is thus affected by the vulnerability described
in the previous commit.

To mitigate this attack, avoid using a fixed-size buffer, and instead
rely on getline() to allocate a buffer as large as necessary to fit the
entire content of the line, preventing any protocol injection.

In most parts of Git we don't assume that every platform has getline().
But libsecret is primarily used on Linux, where we do already assume it
(using a knob in config.mak.uname). POSIX also added getline() in 2008,
so we'd expect other recent Unix-like operating systems to have it
(e.g., FreeBSD also does).

Note that the buffer was already allocated on the heap in this case, but
we'll swap `g_free()` for `free()`, since it will now be allocated by
the system `getline()`, rather than glib's `g_malloc()`.

Taylor Blau 048b673d72 contrib/credential: remove 'gnome-keyring' credential helper
libgnome-keyring was deprecated in 2014 (in favor of libsecret), more
than nine years ago [1].

The credential helper implemented using libgnome-keyring has had a small
handful of commits since 2013, none of which implemented or changed any
functionality. The last commit to do substantial work in this area was
15f7221686 (contrib/git-credential-gnome-keyring.c: support really
ancient gnome-keyring, 2013-09-23), just shy of nine years ago.

This credential helper suffers from the same `fgets()`-related injection
attack (using the new "wwwauth[]" feature) as in the previous commit.
Instead of patching it, let's remove this helper as deprecated.

Taylor Blau 5747c8072b contrib/credential: avoid fixed-size buffer in osxkeychain
The macOS Keychain-based credential helper reads the newline-delimited
protocol stream one line at a time by repeatedly calling fgets() into a
fixed-size buffer, and is thus affected by the vulnerability described
in the previous commit.

To mitigate this attack, avoid using a fixed-size buffer, and instead
rely on getline() to allocate a buffer as large as necessary to fit the
entire content of the line, preventing any protocol injection.

We solved a similar problem in a5bb10fd5e (config: avoid fixed-sized
buffer when renaming/deleting a section, 2023-04-06) by switching to
strbuf_getline(). We can't do that here because the contrib helpers do
not link with the rest of Git, and so can't use a strbuf. But we can use
the system getline() directly, which works similarly.

In most parts of Git we don't assume that every platform has getline().
But this helper is run only on OS X, and that platform added support in
10.7 ("Lion") which was released in 2011.

Edwin Kofler 197152098a completion: suppress unwanted unescaping of `read`
The function `__git_eread`, which reads the first line from the file,
calls the `read` builtin without passing the flag option `-r`.  When
the `read` builtin is called without the flag `-r`, it processes the
backslash escaping in the text that it reads.  For this reason, it is
generally considered the best practice to always use the `read`
builtin with flag `-r` unless one intensionally processes the
backslash escaping.  For the present case in git-prompt.sh, in fact,
all the occurrences of the calls of `__git_eread` intend to read the
literal content of the first lines.

To make it read the first line literally, pass the flag `-r` to the
`read` builtin in the function `__git_eread`.

SZEDER Gábor 138ef8068c cocci: remove 'unused.cocci'
When 'unused.cocci' was added in 4f40f6cb73 (cocci: add and apply a
rule to find "unused" strbufs, 2022-07-05) it found three unused
strbufs, and when it was generalized in the next commit it managed to
find an unused string_list as well.  That's four unused variables in
over 17 years, so apparently we rarely make this mistake.

Unfortunately, applying 'unused.cocci' is quite expensive, e.g. it
increases the from-scratch runtime of 'make coccicheck' by over 5:30
minutes or over 160%:

  $ make -s cocciclean
  $ time make -s coccicheck
      * new spatch flags

  real    8m56.201s
  user    0m0.420s
  sys     0m0.406s
  $ rm contrib/coccinelle/unused.cocci contrib/coccinelle/tests/unused.*
  $ make -s cocciclean
  $ time make -s coccicheck
      * new spatch flags

  real    3m23.893s
  user    0m0.228s
  sys     0m0.247s

That's a lot of runtime spent for not much in return, and arguably an
unused struct instance sneaking in is not that big of a deal to
justify the significantly increased runtime.

Remove 'unused.cocci', because we are not getting our CPU cycles'
worth.

this rules around for a while in "the_repository.cocci", to help any

conflicts with these changes, but eventually we'll remove the
"the_repository.cocci" as a follow-up.

So even if some of these functions are subsequently moved and/or split

and when that happens the we should be removing these rules anyway.

Felipe Contreras 7ee1af8cb8 completion: prompt: use generic colors
When the prompt command mode was introduced in 1bfc51ac81 (Allow
__git_ps1 to be used in PROMPT_COMMAND, 2012-10-10), the assumption was
that it was necessary in order to properly add colors to PS1 in bash,
but this wasn't true.

It's true that the \[ \] markers add the information needed to properly
calculate the width of the prompt, and they have to be added directly to
PS1, a function returning them doesn't work.

But that is because bash coverts the \[ \] markers in PS1 to \001 \002,
which is what readline ultimately needs in order to calculate the width.

We don't need bash to do this conversion, we can use \001 \002
ourselves, and then the prompt command mode is not necessary to display
colors.

This is what functions returning colors are supposed to do [1].

Ævar Arnfjörð Bjarmason 99370863e2 cocci & cache-tree.h: migrate "write_cache_as_tree" to "*_index_*"
Add a trivial rule for "write_cache_as_tree" to
"index-compatibility.cocci", and apply it. This was left out of the
rules added in 0e6550a2c6 (cocci: add a
index-compatibility.pending.cocci, 2022-11-19) because this
compatibility wrapper lived in "cache-tree.h", not "cache.h"

But it's like the other "USE_THE_INDEX_COMPATIBILITY_MACROS", so let's
migrate it too.

The replacement of "USE_THE_INDEX_COMPATIBILITY_MACROS" here with
"USE_THE_INDEX_VARIABLE" is a manual change on top, now that these
files only use "&the_index", and don't need any compatibility
macros (or functions).

The wrapping of some argument lists is likewise manual, as coccinelle
would otherwise give us overly long argument lists.

The reason for putting the "O" in the cocci rule on the "-" and "+"
lines is because I couldn't get correct whitespacing otherwise,
i.e. I'd end up with "oid,&the_index", not "oid, &the_index".

identifier.

Jeff King 64685cb855 git-jump: move valid-mode check earlier
We check if the "mode" argument supplied by the user is valid by seeing
if we have a mode_$mode function defined. But we don't do that until
after creating the tempfile. This is wasteful (we create a tempfile but
never use it), and makes it harder to add new options (the recent stdout
option exits before creating the tempfile, so it misses the check and
"git jump --stdout foo" will produce "git-jump: 92: mode_foo: not found"
rather than the regular usage message).

Apply "index-compatibility.pending.cocci" rule to "builtin/*", but
exclude those where we conflict with in-flight changes.

As a result some of them end up using only "the_index", so let's have
them use the more narrow "USE_THE_INDEX_VARIABLE" rather than
"USE_THE_INDEX_COMPATIBILITY_MACROS".

Manual changes not made by coccinelle, that were squashed in:

* Whitespace-wrap argument lists for repo_hold_locked_index(),
  repo_read_index_preload() and repo_refresh_and_write_index(), in cases
  where the line became too long after the transformation.
* Change "refresh_cache()" to "refresh_index()" in a comment in
  "builtin/update-index.c".
* For those whose call was followed by perror("<macro-name>"), change
  it to perror("<function-name>"), referring to the new function.

Mostly apply the part of "index-compatibility.pending.cocci" that
renames the global variables like "active_nr", which are a shorthand
to referencing (in that case) a struct member as "the_index.cache_nr".

In doing so move more of "index-compatibility.pending.cocci" to
"index-compatibility.cocci".

In the case of "active_nr" we'd have a textual conflict with
"ab/various-leak-fixes" in "next"[1]. Let's exclude that specific case
while moving the rule over from "pending".

Apply a selection of rules in "index-compatibility.pending.cocci"
tree-wide, and in doing so migrate them to
"index-compatibility.cocci".

As in preceding commits the only manual changes here are the macro
removals in "cache.h", and the update to the '*.cocci" rules. The rest
of the C code changes are the result of applying those updated rules.

Move rules for some rarely used cache compatibility macros from
"index-compatibility.pending.cocci" to "index-compatibility.cocci" and
apply them.

Ævar Arnfjörð Bjarmason 0e6550a2c6 cocci: add a index-compatibility.pending.cocci
Add a coccinelle rule which covers the rest of the macros guarded by
"USE_THE_INDEX_COMPATIBILITY_MACROS" cache.h. If the result of this
were applied it can be reduced down to just:

	#ifdef USE_THE_INDEX_COMPATIBILITY_MACROS
	extern struct index_state the_index;
	#endif

But that patch is just under 2000 lines, so let's first add this as a
"pending", and then incrementally pick changes from it in subsequent
commits. In doing that we'll migrate rules from this
"index-compatibility.pending.cocci" to the "index-compatibility.cocci"
created in a preceding commit.

Ævar Arnfjörð Bjarmason fbc1ed629e cocci & cache.h: remove rarely used "the_index" compat macros
Since 4aab5b46f4 (Make read-cache.c "the_index" free., 2007-04-01)
we've been undergoing a slow migration away from these macros, but
haven't made much progress since f8adbec9fe (cache.h: flip
NO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24).

Let's move forward a bit by changing the users of those macros that
are rare enough that we can convert them in one go, and then remove
the compatibility shim.

The only manual change to the C code here is to "cache.h", the rest is
all the result of applying the new "index-compatibility.cocci".

Even though it's a one-off, let's keep the coccinelle rules for
now. We'll extend them in subsequent commits, and this will help
anything that's in-flight or out-of-tree to migrate.
