through the percent signs in the string "fmt", but we're not interested
in its effect on the strbuf "dummy". Use strchr(3) instead and get rid

hex2chr() takes care not to run over the end of a NUL-terminated string.
It's used in packet_length(), but both callers of that function pass a
four-byte buffer, making NUL-checks unnecessary. packet_length() could
accidentally be used with a pointer to a buffer of unknown size at new
call-sites, though, and the compiler wouldn't complain.
Add a size parameter plus check, and remove the NUL-checks by calling
hexval() directly. This trades three NUL checks against one size check
and the ability to report the use of a short buffer at runtime.
If any of the four bytes is NUL or -- more generally -- not a
hexadecimal digit, then packet_length() still returns a negative value.

git ls-tree has two prefixes: The one handed to cmd_ls_tree(), i.e. the
current subdirectory in the repository (if any) and the "display" prefix
used by the show_tree_*() functions. The option --full-name clears the
last one, i.e. it shows full paths, and --full-tree clears both, i.e. it
acts as if the command was started in the root of the repository.
The show_tree_*() functions use the ls_tree_options members chomp_prefix
and ls_tree_prefix to determine their prefix values. Calculate it once
in cmd_ls_tree() instead, once the main prefix value is finalized.
This allows chomp_prefix to become a local variable. Stop using
strlen(3) to determine its initial value -- we only care whether we got
a non-empty string, not precisely how long it is.
Rename ls_tree_prefix to prefix to demonstrate that we converted all
users and because the ls_tree_ part is no longer necessary since
030a3d5d9e (ls-tree: use a "struct options", 2023-01-12) turned it from
a global variable to a struct member.

In some shells, such as bash and zsh, it's possible to use a command
substitution to provide the output of a command as a file argument to
another process, like so:
diff -u <(printf "a\nb\n") <(printf "a\nc\n")
However, this syntax does not produce useful results with "git diff
--no-index". On macOS, the arguments to the command are named pipes
under /dev/fd, and git diff doesn't know how to handle a named pipe. On
Linux, the arguments are symlinks to pipes, so git diff "helpfully"
diffs these symlinks, comparing their targets like "pipe:[1234]" and
"pipe:[5678]".
To address this "diff --no-index" is changed so that if a path given on
the commandline is a named pipe or a symbolic link that resolves to a
named pipe then we read the data to diff from that pipe. This is
implemented by generalizing the code that already exists to handle
reading from stdin when the user passes the path "-".
If the user tries to compare a named pipe to a directory then we die as
we do when trying to compare stdin to a directory.
As process substitution is not support by POSIX this change is tested by
using a pipe and a symbolic link to a pipe.

If there is an error when reading from stdin then "diff --no-index"
prints an error message but continues to try and diff a file named "-"
resulting in an error message that looks like
error: error while reading from stdin: Invalid argument
fatal: stat '-': No such file or directory
assuming that no file named "-" exists. If such a file exists it prints
the first error message and generates the diff from that file which is
not what the user wanted. Instead just die() straight away if we cannot
read from stdin.

When the user runs
git diff --no-index file directory
we follow the behavior of POSIX diff and rewrite the arguments as
git diff --no-index file directory/file
Doing that when "file" is "-" (which means "read from stdin") does not
make sense so we should error out if the user asks us to compare "-" to
a directory. This matches the behavior of GNU diff and diff on *BSD.

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.)

alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for

This table was originally introduced to solely be used with kwset
machinery (0f871cf56e), so it would make sense for it to belong in
kwset.[ch] rather than ctype.c and git-compat-util.h. It is only used in
diffcore-pickaxe.c, which already includes kwset.h so no other headers

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).

The tutorial in Documentation/MyFirstObjectWalk.txt
contains the functions trace_printf(), oid_to_hex(),
and pp_commit_easy(), and struct oidset, which are used
without any hint of where they are defined. When the provided
code is compiled, the compiler returns an error, stating that
the functions and the struct are used before declaration. Therefore,include
necessary header files (the ones which have no mentions in the tutorial).
