In the first test in this script, 'creates a report with content in the
right places', we generate a report and pipe it into our helper
`check_all_headers_populated()`. The idea of the helper is to find all
lines that look like headers ("[Some Header Here]") and to check that
the next line is non-empty. This is supposed to catch erroneous outputs
such as the following:
[A Header]
something
more here
[Another Header]
[Too Early Header]
contents
However, we provide the lines of the bug report as filenames to grep,
meaning we mostly end up spewing errors:
grep: : No such file or directory
grep: [System Info]: No such file or directory
grep: git version:: No such file or directory
grep: git version 2.41.0.2.gfb7d80edca: No such file or directory
This doesn't disturb the test, which tugs along and reports success, not
really having verified the contents of the report at all.
Note that after 788a776069 ("bugreport: collect list of populated
hooks", 2020-05-07), the bug report, which is created in our hook-less
test repo, contains an empty section with the enabled hooks. Thus, even
the intention of our helper is a bit misguided: there is nothing
inherently wrong with having an empty section in the bug report.
Let's instead split this test into three: first verify that we generate
a report at all, then check that the introductory blurb looks the way it
should, then verify that the "[System Info]" seems to contain the right
things. (The "[Enabled Hooks]" section is tested later in the script.)

The imap_cmd_cb struct has several fields which are totally unused.
Presumably they did useful things in the upstream isync code from which
this is derived, but they don't in our more limited program. This is
particularly confusing for the "done" callback, which (as of the
previous patch) no longer matches the signature of the adjacent "cont"
callback.
Since we're unlikely to share code with isync going forward, we should
feel free to simplify the code here. Note that "done" is examined but
never set, so we can also drop a little bit of code outside of the
struct definition.

There's a generic callback mechanism for handling plus-continuation of
IMAP commands. It takes the imap_cmd struct itself as an argument. That
seems reasonable, and in a larger imap-using program it might be used.
But in imap-send, we have only one such callback (auth_cram_md5) and it
doesn't use this value, triggering -Wunused-parameter warnings.
We could just mark the parameter as UNUSED. But since this is the only
such function, and because we are not likely to share code with the
upstream isync anymore, we can just simplify the interface to remove
this parameter.

Our caller passes in an imap_server_conf struct, but we ignore it
totally, and instead read the config directly from the global "server"
variable. This works OK, since our sole caller will pass in that same
global variable. But the intent seems to have been to use the passed-in
variable, as otherwise it has no purpose (and many other functions use
the same pattern).
Let's use the passed-in value, which also silences a -Wunused-parameter
warning.
It would be nice if "server" was not a global here, as we could avoid
making similar mistakes. But changing that would be a larger refactor,
as it must be accessed as a global in a few spots (e.g., filling it in
with the config callback).

When reporting a problem, `git fsck` emits a message such as:
missing blob 1234abcd (:file)
However, this can be ambiguous when the problem is detected in the index
of a worktree other than the one in which `git fsck` was invoked. To
address this shortcoming, 592ec63b38 (fsck: mention file path for index
errors, 2023-02-24) enhanced the output to mention the path of the index
when the problem is detected in some other worktree:
missing blob 1234abcd (.git/worktrees/wt/index:file)
Unfortunately, the variable in fsck_index() which controls whether the
index path should be shown is misleadingly named "is_main_index" which
can be misunderstood as referring to the main worktree (i.e. the one
housing the .git/ repository) rather than to the current worktree (i.e.
the one in which `git fsck` was invoked). Avoid such potential confusion
by choosing a name more reflective of its actual purpose.

- Check that we can describe a commit that is not tagged (that is,
for example our HEAD is at least one commit ahead of some reachable
commit which is tagged) with at least <number> digits of the oid
being used for describing it.
- Check that when using such a commit-ish, we always use at least
<number> digits of the oid to describe it.
- Check that we can describe a tag. This just gives the name of the

In 03267e8656 (commit: discard partial cache before (re-)reading it,
2022-11-08), a memory leak was plugged by discarding any partial index
before re-reading it.
The problem with this memory leak fix is that it was based on an
incomplete understanding of the logic introduced in 7168624c35 (Do not
generate full commit log message if it is not going to be used,
2007-11-28).
That logic was introduced to add a shortcut when committing without
editing the commit message interactively. A part of that logic was to
ensure that the index was read into memory:
if (!active_nr && read_cache() < 0)
die(...)
Translation to English: If the index has not yet been read, read it, and
if that fails, error out.
That logic was incorrect, though: It used `!active_nr` as an indicator
that the index was not yet read. Usually this is not a problem because
in the vast majority of instances, the index contains at least one
entry.
And it was natural to do it this way because at the time that condition
was introduced, the `index_state` structure had no explicit flag to
indicate that it was initialized: This flag was only introduced in
913e0e99b6 (unpack_trees(): protect the handcrafted in-core index from
read_cache(), 2008-08-23), but that commit did not adjust the code path
where no index file was found and a new, pristine index was initialized.
Now, when the index does not contain any entry (which is quite
common in Git's test suite because it starts quite a many repositories
from scratch), subsequent calls to `do_read_index()` will mistake the
index not to be initialized, and read it again unnecessarily.
This is a problem because after initializing the empty index e.g. the
`cache_tree` in that index could have been initialized before a
subsequent call to `do_read_index()` wants to ensure an initialized
index. And if that subsequent call mistakes the index not to have been
initialized, it would lead to leaked memory.
The correct fix for that memory leak is to adjust the condition so that
it does not mistake `active_nr == 0` to mean that the index has not yet
been read.
Using the `initialized` flag instead, we avoid that mistake, and as a
bonus we can fix a bug at the same time that was introduced by the
memory leak fix: When deleting all tracked files and then asking `git
commit -a -m ...` to commit the result, Git would internally update the
index, then discard and re-read the index undoing the update, and fail
to commit anything.

We are about to fix an ancient bug where `do_read_index()` pretended
that the index was not initialized when there are no index entries.
Before the `index_state` structure gained the `initialized` flag in
913e0e99b6 (unpack_trees(): protect the handcrafted in-core index from
read_cache(), 2008-08-23), that was the best we could do (even if it was
incorrect: it is totally possible to read a Git index file that contains
no index entries).
This pattern was repeated also in 998330ac2e (read-cache: look for
shared index files next to the index, too, 2021-08-26), which we fix
here by _not_ mistaking an empty base index for a missing
`sharedindex.*` file.

In 913e0e99b6 (unpack_trees(): protect the handcrafted in-core index
from read_cache(), 2008-08-23) a flag was introduced into the
`index_state` structure to indicate whether it had been initialized (or
more correctly: read and parsed).
There was one code path that was not handled, though: when the index
file does not yet exist (but the `must_exist` parameter is set to 0 to
indicate that that's okay). In this instance, Git wants to go forward
with a new, pristine Git index, almost as if the file had existed and
contained no index entries or extensions.
Since Git wants to handle this situation the same as if an "empty" Git
index file existed, let's set the `initialized` flag also in that case.
This is necessary to prepare for fixing the bug where the condition
`cache_nr == 0` is incorrectly used as an indicator that the index was
already read, and the condition `initialized != 0` needs to be used
instead.

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.

There is a code path starting from trace2_def_param_fl() that eventually
calls current_config_scope(), and thus it needs to have "kvi" plumbed
through it. Additional plumbing is also needed to get "kvi" to
trace2_def_param_fl(), which gets called by two code paths:
- Through tr2_cfg_cb(), which is a config callback, so it trivially
receives "kvi" via the "struct config_context ctx" parameter.
- Through tr2_list_env_vars_fl(), which is a high level function that
lists environment variables for tracing. This has been secretly
behaving like git_config_from_parameters() (in that it parses config
from environment variables/the CLI), but does not set config source
information.

Pass config_context when parsing CLI config. To provide the .kvi member,
refactor out kvi_from_param() from the logic that caches CLI config in
configsets. Now that config_context and config_context.kvi is always
present when config machinery calls config callbacks, plumb "kvi" so
that we can remove all calls of current_config_scope() except for
trace2/*.c (which will be handled in a later commit), and remove all
other current_config_*() (the functions themselves and their calls).
Note that this results in .kvi containing a different, more complete
set of information than the mocked up "struct config_source" in
git_config_from_parameters().
Plumbing "kvi" reveals a few places where we've been doing the wrong
thing:
* git_config_parse_parameter() hasn't been setting config source
information, so plumb "kvi" there too.
* Several sites in builtin/config.c have been calling current_config_*()
functions outside of config callbacks (indirectly, via the
format_config() helper), which means they're reading state that isn't
set correctly:
* "git config --get-urlmatch --show-scope" iterates config to collect
values, but then attempts to display the scope after config
iteration, causing the "unknown" scope to be shown instead of the
config file's scope. It's clear that this wasn't intended: we knew
that "--get-urlmatch" couldn't show config source metadata, which is
why "--show-origin" was marked incompatible with "--get-urlmatch"
when it was introduced [1]. It was most likely a mistake that we
allowed "--show-scope" to sneak through.
Fix this by copying the "kvi" value in the collection phase so that
it can be read back later. This means that we can now support "git
config --get-urlmatch --show-origin", but that is left unchanged
for now.
* "git config --default" doesn't have config source metadata when
displaying the default value, so "--show-scope" also results in
"unknown", and "--show-origin" results in a BUG(). Fix this by
treating the default value as if it came from the command line (e.g.
like we do with "git -c" or "git config --file"), using
kvi_from_param().

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.

comes from 4a72486de9 ("fix cherry-pick/revert status after commit",
2019-04-17). This commit modified wt_status_get_state() in order to
detect that a cherry-pick was in progress even if the user has used `git
commit` in the middle of the sequence.
The check used to detect this is the call to sequencer_get_last_command.
If the sequencer indicates that the lass command was a REPLAY_PICK, then
the state->cherry_pick_in_progress is set to 1 and the
cherry_pick_head_oid is initialized to the null_oid. Similar behavior is
done for the case of REPLAY_REVERT.
It happens that this call of sequencer_get_last_command will always
report the action even if the user hasn't interrupted anything. Thus,
during a range of cherry-picks or reverts, the cherry_pick_head_oid and
revert_head_oid will always be overwritten and initialized to the null
oid.
This results in status always displaying the terse message which does
not include commit information.
Fix this by adding an additional check so that we do not re-initialize
the cherry_pick_head_oid or revert_head_oid if we have already set the
cherry_pick_in_progress or revert_in_progress bits. This ensures that
git status will display the more helpful information when its available.
Add a test case covering this behavior.

Much like with attributes files, sometimes programs would like to know
the location of configuration files at the global or system levels.
However, it isn't always clear where these may live, especially for the
system file, which may have been hard-coded at compile time or computed
dynamically based on the runtime prefix.
Since other parties cannot intuitively know how Git was compiled and
where it looks for these files, help them by providing variables that
can be queried. Because we have multiple paths for global config
values, print them in order from highest to lowest priority, and be sure
to split on newlines so that "git var -l" produces two entries for the
global value.
However, be careful not to split all values on newlines, since our
editor values could well contain such characters, and we don't want to
split them in such a case.
Note in the documentation that some values may contain multiple paths
and that callers should be prepared for that fact. This helps people
write code that will continue to work in the event we allow multiple
items elsewhere in the future.

Currently, there are some programs which would like to read and parse
the gitattributes files at the global or system levels. However, it's
not always obvious where these files live, especially for the system
file, which may have been hard-coded at compile time or computed
dynamically based on the runtime prefix.
It's not reasonable to expect all callers of Git to intuitively know
where the Git distributor or user has configured these locations to
be, so add some entries to allow us to determine their location. Honor
the GIT_ATTR_NOSYSTEM environment variable if one is specified. Expose
the accessor functions in a way that we can reuse them from within the
var code.
In order to make our paths consistent on Windows and also use the same
form as paths use in "git rev-parse", let's normalize the path before we
return it. This results in Windows-style paths that use slashes, which
is convenient for making our tests function in a consistent way across
platforms. Note that this requires that some of our values be freed, so
let's add a flag about whether the value needs to be freed and use it
accordingly.

Right now, the functions which determine the current system and global
gitattributes files are not exposed. We'd like to use them in a future
commit, but they're not ideally named. Rename them to something more
suitable as a public interface, expose them, and document them.
