Earlier patches annotating unused parameters in imap-send missed a few
cases in code that is compiled only with NO_OPENSSL. These need to
retain the extra parameters to match the interfaces used when we compile
with openssl support.
Note in the case of socket_perror() that the function declaration and
parts of its code are shared between the two cases, and only the openssl
code looks at "sock". So we can't simply mark the parameter as always
unused. Instead, we can add a noop statement that references it. This is
ugly, but should be portable.

imap-send: drop unused fields from imap_cmd_cb
imap-send: drop unused parameter from imap_cmd_cb callback
imap-send: use server conf argument in setup_curl()
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).

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.

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.

As discussed in 644de29e22 (http: drop support for curl < 7.19.4,
2021-07-30) checking against LIBCURL_VERSION_NUM isn't as reliable as
checking specific symbols present in curl, as some distros have been
known to backport features.
However, while some of the curl_easy_setopt() arguments we rely on are
macros, others are enum, and we can't assume that those that are
macros won't change into enums in the future.
So we're still going to have to check LIBCURL_VERSION_NUM, but by
doing that in one central place and using a macro definition of our
own, anyone who's backporting features can define it themselves, and
thus have access to more modern curl features that they backported,
even if they didn't bump the LIBCURL_VERSION_NUM.
More importantly, as shown in a preceding commit doing these version
checks makes for hard to read and possibly buggy code, as shown by the
bug fixed there where we were conflating base 10 for base 16 when
comparing the version.
By doing them all in one place we'll hopefully reduce the chances of
such future mistakes, furthermore it now becomes easier to see at a
glance what the oldest supported version is, which makes it easier to
reason about any future deprecation similar to the recent
e48a623dea (Merge branch 'ab/http-drop-old-curl', 2021-08-24).

In the last commit we dropped support for curl < 7.11.1, let's
continue that and drop support for versions older than 7.16.0. This

Choosing 7.16.0 is a somewhat arbitrary cutoff:
1. It came out in October of 2006, almost 15 years ago.
Besides being a nice round number, around 10 years is
a common end-of-life support period, even for conservative
distributions.
2. That version introduced the curl_multi interface, which
gives us a lot of bang for the buck in removing #ifdefs
RHEL 5 came with curl 7.15.5[1] (released in August 2006). RHEL 5's
extended life cycle program ended on 2020-11-30[1]. RHEL 6 comes with
curl 7.19.7 (released in November 2009), and RHEL 7 comes with
7.29.0 (released in February 2013).

We eventually want to drop the argv_array name and just use strvec

Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts remaining files from the first half of the alphabet,
to keep the diff to a manageable size.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '

Every program which links against libgit.a must call this
function, or risk hitting an assert() in system_path() that
checks whether we have configured argv0_path (though only
when RUNTIME_PREFIX is defined, so essentially only on
Windows).
Looking at the diff, you can see that putting it into the
common main() saves us having to do it individually in each
of the external commands. But what you can't see are the
cases where we _should_ have been doing so, but weren't
(e.g., git-credential-store, and all of the t/helper test
programs).
This has been an accident-waiting-to-happen for a long time,
but wasn't triggered until recently because it involves one
of those programs actually calling system_path(). That
happened with git-credential-store in v2.8.0 with ae5f677
(lazily load core.sharedrepository, 2016-03-11). The
program:
- takes a lock file, which...
- opens a tempfile, which...
- calls adjust_shared_perm to fix permissions, which...
- lazy-loads the config (as of ae5f677), which...
- calls system_path() to find the location of
/etc/gitconfig
On systems with RUNTIME_PREFIX, this means credential-store
reliably hits that assert() and cannot be used.
We never noticed in the test suite, because we set
GIT_CONFIG_NOSYSTEM there, which skips the system_path()
lookup entirely. But if we were to tweak git_config() to
find /etc/gitconfig even when we aren't going to open it,
then the test suite shows multiple failures (for
credential-store, and for some other test helpers). I didn't
include that tweak here because it's way too specific to
this particular call to be worth carrying around what is
essentially dead code.
The implementation is fairly straightforward, with one
exception: there is exactly one caller (git.c) that actually
cares about the result of the function, and not the
side-effect of setting up argv0_path. We can accommodate
that by simply replacing the value of argv[0] in the array
we hand down to cmd_main().

There are certain startup tasks that we expect every git
process to do. In some cases this is just to improve the
quality of the program (e.g., setting up gettext()). In
others it is a requirement for using certain functions in
libgit.a (e.g., system_path() expects that you have called
git_extract_argv0_path()).
Most commands are builtins and are covered by the git.c
version of main(). However, there are still a few external
commands that use their own main(). Each of these has to
remember to include the correct startup sequence, and we are
not always consistent.
Rather than just fix the inconsistencies, let's make this
harder to get wrong by providing a common main() that can
run this standard startup.
We basically have two options to do this:
- the compat/mingw.h file already does something like this by
adding a #define that replaces the definition of main with a
wrapper that calls mingw_startup().
The upside is that the code in each program doesn't need
to be changed at all; it's rewritten on the fly by the
preprocessor.
The downside is that it may make debugging of the startup
sequence a bit more confusing, as the preprocessor is
quietly inserting new code.
- the builtin functions are all of the form cmd_foo(),
and git.c's main() calls them.
This is much more explicit, which may make things more
obvious to somebody reading the code. It's also more
flexible (because of course we have to figure out _which_
cmd_foo() to call).
The downside is that each of the builtins must define
cmd_foo(), instead of just main().
This patch chooses the latter option, preferring the more
explicit approach, even though it is more invasive. We
introduce a new file common-main.c, with the "real" main. It
expects to call cmd_main() from whatever other objects it is
linked against.
We link common-main.o against anything that links against
libgit.a, since we know that such programs will need to do
this setup. Note that common-main.o can't actually go inside
libgit.a, as the linker would not pick up its main()
function automatically (it has no callers).
The rest of the patch is just adjusting all of the various
external programs (mostly in t/helper) to use cmd_main().
I've provided a global declaration for cmd_main(), which
means that all of the programs also need to match its
signature. In particular, many functions need to switch to
"const char **" instead of "char **" for argv. This effect
ripples out to a few other variables and functions, as well.
This makes the patch even more invasive, but the end result
is much better. We should be treating argv strings as const
anyway, and now all programs conform to the same signature
(which also matches the way builtins are defined).

We frequently allocate strings as xmalloc(len + 1), where
the extra 1 is for the NUL terminator. This can be done more
simply with xmallocz, which also checks for integer
overflow.
There's no case where switching xmalloc(n+1) to xmallocz(n)
is wrong; the result is the same length, and malloc made no
guarantees about what was in the buffer anyway. But in some
cases, we can stop manually placing NUL at the end of the
allocated buffer. But that's only safe if it's clear that
the contents will always fill the buffer.
In each case where this patch does so, I manually examined
the control flow, and I tried to err on the side of caution.

It's a common pattern to do:
foo = xmalloc(strlen(one) + strlen(two) + 1 + 1);
sprintf(foo, "%s %s", one, two);
(or possibly some variant with strcpy()s or a more
complicated length computation). We can switch these to use
xstrfmt, which is shorter, involves less error-prone manual
computation, and removes many sprintf and strcpy calls which
make it harder to audit the code for real buffer overflows.

According to the cURL documentation for the CURLOPT_USE_SSL option,
it is only used with plain text protocols that get upgraded to SSL
using the STARTTLS command.
The server.use_ssl variable is only set when we are using a protocol
that is already SSL/TLS (i.e. imaps), so setting CURLOPT_USE_SSL
when the server.use_ssl variable is set has no effect whatsoever.
Instead, set CURLOPT_USE_SSL to CURLUSESSL_TRY when the server.use_ssl
variable is NOT set so that cURL will attempt to upgrade the plain
text connection to SSL/TLS using STARTTLS in that case.
This much more closely matches the behavior of the non-cURL code path.

Use libcurl's high-level API functions to implement git-imap-send
instead of the previous low-level OpenSSL-based functions.
Since version 7.30.0, libcurl's API has been able to communicate with
IMAP servers. Using those high-level functions instead of the current
ones would reduce imap-send.c by some 1200 lines of code. For now,
the old ones are wrapped in #ifdefs, and the new functions are enabled
by make if curl's version is >= 7.34.0, from which version on curl's
CURLOPT_LOGIN_OPTIONS (enabling IMAP authentication) parameter has been
available. The low-level functions will still be used for tunneling
into the server for now.
As I don't have access to that many IMAP servers, I haven't been able to
test the new code with a wide variety of parameter combinations. I did
test both secure and insecure (imaps:// and imap://) connections and
values of "PLAIN" and "LOGIN" for the authMethod.
In order to suppress a sparse warning about "using sizeof on a
function", we use the same solution used in commit 9371322a6
("sparse: suppress some "using sizeof on a function" warnings",
06-10-2013) which solved exactly this problem for the other commands
using libcurl.
