8774aa56ad send-email: relay '-v N' to format-patch
send-email relays unrecognized arguments to its format-patch call.
Passing '-v N' leads to an error because -v is consumed as
send-email's --validate.  For example,

  git send-email -v 3 @{u}

fails with

  fatal: ambiguous argument '3': unknown revision or path not in the
  working tree.  [...]

To prevent this, add the short --reroll-count option to send-email's
main option list and explicitly provide it to the format-patch call.

There other format-patch options that send-email doesn't relay
properly, including at least -n, -N, and the diff option -D.  Punt on
these because dealing with them is more complicated:

 * they would require configuring send-email to not ignore option case

 * send-email makes three GetOptions() calls with different sets of
   options, the last being the main set of options.  Unlike -v, which
   is consumed by the last GetOptions call, the -n, -N, and -D options
   are consumed as abbreviations by the earlier calls.

a755530454 send-email: use 'git hook run' for 'sendemail-validate'
Change the "sendmail-validate" hook to be run via the "git hook run"
wrapper instead of via a direct invocation.

This is the smallest possibly change to get "send-email" using "git
hook run". We still check the hook itself with "-x", and set a
"GIT_DIR" variable, both of which are asserted by our tests. We'll
need to get rid of this special behavior if we start running N hooks,
but for now let's be as close to bug-for-bug compatible as possible.

2b7b75850c send-email: programmatically generate bash completions
"git send-email --git-completion-helper" only prints "format-patch"
flags. Make it print "send-email" flags as well, extracting them
programmatically from its three existing "GetOptions".

Introduce a "uniq" subroutine, otherwise --cc-cover, --to-cover and
other flags would show up twice. In addition, deduplicate flags common
to both "send-email" and "format-patch", like --from.

Remove extraneous flags: --h and --git-completion-helper.

Add trailing "=" to options that expect an argument, inline with
the format-patch implementation.

Add a completion test for "send-email --validate", a send-email flag.

b996f84989 send-email: fix a "first config key wins" regression in v2.33.0
Fix a regression in my c95e3a3f0b (send-email: move trivial config
handling to Perl, 2021-05-28) where we'd pick the first config key out
of multiple defined ones, instead of using the normal "last key wins"
semantics of "git config --get".

This broke e.g. cases where a .git/config would have a different
sendemail.smtpServer than ~/.gitconfig. We'd pick the ~/.gitconfig
over .git/config, instead of preferring the repository-local
version. The same would go for /etc/gitconfig etc.

The full list of impacted config keys (the %config_settings values
which are references to scalars, not arrays) is:

    sendemail.smtpencryption
    sendemail.smtpserver
    sendemail.smtpserverport
    sendemail.smtpuser
    sendemail.smtppass
    sendemail.smtpdomain
    sendemail.smtpauth
    sendemail.smtpbatchsize
    sendemail.smtprelogindelay
    sendemail.tocmd
    sendemail.cccmd
    sendemail.aliasfiletype
    sendemail.envelopesender
    sendemail.confirm
    sendemail.from
    sendemail.assume8bitencoding
    sendemail.composeencoding
    sendemail.transferencoding
    sendemail.sendmailcmd

I.e. having any of these set in say ~/.gitconfig and in-repo
.git/config regressed in v2.33.0 to prefer the --global one over the
--local.

To test this add a test of config priority to one of these config
variables, most don't have tests at all, but there was an existing one
for sendemail.8bitEncoding.

The "git config" (instead of "test_config") is somewhat of an
anti-pattern, but follows established conventions in
t9001-send-email.sh, likewise with any other pattern or idiom in this
test.

The populating of home/.gitconfig and setting of HOME= is copied from
a test in t0017-env-helper.sh added in 1ff750b128 (tests: make
GIT_TEST_GETTEXT_POISON a boolean, 2019-06-21). This test fails
without this bugfix, but now it works.

e082113484 send-email: avoid incorrect header propagation
If multiple independent patches are sent with send-email, even if the
"In-Reply-To" and "References" headers are not managed by --thread or
--in-reply-to, their values may be propagated from prior patches to
subsequent patches with no such headers defined.

To mitigate this and potential future issues, make sure all global
patch-specific variables are always either handled by
command-specific code (e.g. threading), or are reset to their default
values for every iteration.

c95e3a3f0b send-email: move trivial config handling to Perl
Optimize the startup time of git-send-email by using an amended
config_regexp() function to retrieve the list of config keys and
values we're interested in.

For boolean keys we can handle the [true|false] case ourselves, and
the "--get" case didn't need any parsing. Let's leave "--path" and
other "--bool" cases to "git config". I'm not bothering with the
"undef" or "" case (true and false, respectively), let's just punt on
those and others and have "git config --type=bool" handle it.

The "grep { defined } @values" here covers a rather subtle case. For
list values such as sendemail.to it is possible as with any other
config key to provide a plain "-c sendemail.to", i.e. to set the key
as a boolean true. In that case the Git::config() API will return an
empty string, but this new parser will correctly return "undef".

However, that means we can end up with "undef" in the middle of a
list. E.g. for sendemail.smtpserveroption in conjuction with
sendemail.smtpserver as a path this would have produce a warning. For
most of the other keys we'd behave the same despite the subtle change
in the value, e.g. sendemail.to would behave the same because
Mail::Address->parse() happens to return an empty list if fed
"undef". For the boolean values we were already prepared to handle
these variables being initialized as undef anyway.

This brings the runtime of "git send-email" from ~60-~70ms to a very
steady ~40ms on my test box. We now run just one "git config"
invocation on startup instead of 8, the exact number will differ based
on the local sendemail.* config. I happen to have 8 of those set.

This brings the runtime of t9001-send-email.sh from ~13s down to ~12s
for me. The change there is less impressive as many of those tests set
various config values, and we're also getting to the point of
diminishing returns for optimizing "git send-email" itself.

17530b2ed2 perl: nano-optimize by replacing Cwd::cwd() with Cwd::getcwd()
It has been pointed out[1] that cwd() invokes "pwd(1)" while getcwd()
is a Perl-native XS function. For what we're using these for we can
use getcwd().

The performance difference is miniscule, we're saving on the order of
a millisecond or so, see [2] below for the benchmark. I don't think
this matters in practice for optimizing git-send-email or perl
execution (unlike the patches leading up to this one).

But let's do it regardless of that, if only so we don't have to think
about this as a low-hanging fruit anymore.

f4dc9432fd send-email: lazily load modules for a big speedup
Optimize the time git-send-email takes to do even the simplest of
things (such as serving up "-h") from around ~150ms to ~80ms-~90ms by
lazily loading the modules it requires.

Before this change Devel::TraceUse would report 99/97 used modules
under NO_GETTEXT=[|Y], respectively. Now it's 52/37. It now takes ~15s
to run t9001-send-email.sh, down from ~20s.

Changing File::Spec::Functions::{catdir,catfile} to invoking class
methods on File::Spec itself is idiomatic. See [1] for a more
elaborate explanation, the resulting code behaves the same way, just
without the now-pointless function wrapper.

fef381e6dc send-email: lazily shell out to "git var"
Optimize git-send-email by only shelling out to "git var" if we need
to. This is easily done by re-inventing our own small version of
perl's Memoize module.

I suppose I could just use Memoize itself, but in a subsequent patch
I'll be micro-optimizing send-email's use of dependencies. Using
Memoize is a measly extra 5-10 milliseconds, but as we'll see that'll
end up mattering for us in the end.

This brings the runtime of a plain "send-email" from around ~160-170ms
to ~140m-150ms. The runtime of the tests is around the same, or around
~20s.

9264d29bf6 send-email: lazily load config for a big speedup
Reduce the time it takes git-send-email to get to even the most
trivial of tasks (such as serving up its "-h" output) by first listing
config keys that exist, and only then only call e.g. "git config
--bool" on them if they do.

Over a lot of runs this speeds the time to "-h" up for me from ~250ms
to ~150ms, and the runtime of t9001-send-email.sh goes from ~25s to
~20s.

This introduces a race condition where we'll do the "wrong" thing if a
config key were to be inserted between us discovering the list and
calling read_config(), i.e. we won't know about the racily added
key. In theory this is a change in behavior, in practice it doesn't
matter.

The config_regexp() function being changed here was added in
dd84e528a3 (git-send-email: die if sendmail.* config is set,
2020-07-23) for use by git-send-email. So we can change its odd return
value in the case where no values are found by "git config". The
difference in the *.pm code would matter if it was invoked in scalar
context, but now it no longer is.

Arguably this caching belongs in Git.pm itself, but in lieu of
modifying it for all its callers let's only do this for "git
send-email". The other big potential win would be "git svn", but
unlike "git send-email" it doesn't check tens of config variables one
at a time at startup (in my brief testing it doesn't check any).

671818ab0b send-email: remove non-working support for "sendemail.smtpssl"
Remove the already dead code to support "sendemail.smtpssl" by finally
removing the dead code supporting the configuration option.

In f6bebd121a (git-send-email: add support for TLS via
Net::SMTP::SSL, 2008-06-25) the --smtp-ssl command-line option was
documented as deprecated, later in 65180c6618 (List send-email config
options in config.txt., 2009-07-22) the "sendemail.smtpssl"
configuration option was also documented as such.

Then in in 3ff15040e2 (send-email: fix regression in
sendemail.identity parsing, 2019-05-17) I unintentionally removed
support for it by introducing a bug in read_config().

As can be seen from the diff context we've already returned unless
$enc i defined, so it's not possible for us to reach the "elsif"
branch here. This code was therefore already dead since Git v2.23.0.

So let's just remove it. We were already 11 years into a stated
deprecation period of this variable when 3ff15040e2 landed, now it's
around 13. Since it hasn't worked anyway for around 2 years it looks
like we can safely remove it.

The --smtp-ssl option is still deprecated, if someone cares they can
follow-up and remove that too, but unlike the config option that one
could still be in use in the wild. I'm just removing this code that's
provably unused already.

Respect core.hooksPath setting, 2021-03-23), meaning that it hasn't

The consensus with Git.pm is that we need to be considerate of
out-of-tree users who treat it as a public documented interface. We
should therefore be less willing to add new functionality to it, least
we be stuck supporting it after our own uses for it disappear.

In this case the git-send-email.perl hook invocation will probably be
replaced by a future "git hook run" command, and in the commit
preceding this one the "hooks_path" become nothing but a trivial
wrapper for "rev-parse --git-path hooks" anyway (with no
Cwd::abs_path() call), so let's just inline this command in
git-send-email.perl itself.

cd5b33fbdc git-send-email: add option to specify sendmail command
The sendemail.smtpServer configuration option and --smtp-server command
line option both support using a sendmail-like program to send emails by
specifying an absolute file path. However, this is not ideal for the
following reasons:

1. It overloads the meaning of smtpServer (now a program is being used
   for the server?)
2. It doesn't allow for non-absolute paths, arguments, or arbitrary
   scripting

Requiring an absolute path is bad for portability, as the same program
may be in different locations on different systems. If a user wishes to
pass arguments to their program, they have to use the smtpServerOption
option, which is cumbersome (as it must be repeated for each option) and
doesn't adhere to normal git conventions.

Introduce a new configuration option sendemail.sendmailCmd as well as a
command line option --sendmail-cmd that can be used to specify a command
(with or without arguments) or shell expression to run to send email.
The name of this option is consistent with --to-cmd and --cc-cmd. This
invocation honors the user's $PATH so that absolute paths are not
necessary. Arbitrary shell expressions are also supported, allowing
users to do basic scripting.

Give this option a higher precedence over --smtp-server and
sendemail.smtpServer, as the new interface is more flexible. For
backward compatibility, continue to support absolute paths in
--smtp-server and sendemail.smtpServer.

 * Don't say "patch contains a" after just mentioning the filename,
   just leave it at "FILE:LINE: is longer than[...]. The "contains a"
   sounded like we were talking about the file in general, when we're
   actually checking it line-by-line.

 * Don't just say "rejected by sendemail-validate hook", but combine

I had an aborted attempt to make the line length checker note all
lines that were longer than the limit. I didn't think that was worth
the effort, but I've left in the testing change to check that we die
as soon as we spot the first long line.

Since the introduction of 'core.hooksPath' configuration option in

Instead of assuming a hardcoded repo relative path, query

f9f60d7066 send-email: restore --in-reply-to superseding behavior
git send-email --in-reply-to= fails to override In-Reply-To email headers,
if they're present in the output of format-patch, even when explicitly

       Make the first mail (or all the mails with --no-thread) appear as

Since "git send-email" learned to take 'auto' as the value for the

3ff15040e2 send-email: fix regression in sendemail.identity parsing
Fix a regression in my recent 3494dfd3ee ("send-email: do defaults ->
config -> getopt in that order", 2019-05-09). I missed that the
$identity variable needs to be extracted from the command-line before
we do the config reading, as it determines which config variable we
should read first. See [1] for the report.

The sendemail.identity feature was added back in
34cc60ce2b ("send-email: Add support for SSL and SMTP-AUTH",
2007-09-03), there were no tests to assert that it worked properly.

So let's fix both the regression, and add some tests to assert that
this is being parsed properly. While I'm at it I'm adding a
--no-identity option to go with --[to|cc|bcc] variable, since the
semantics are similar. It's like to/cc/bcc except that unlike those we
don't support multiple identities, but we could now easily add it
support for it if anyone cares.

In just fixing the --identity command-line parsing bug I discovered
that a narrow fix to that wouldn't do. In read_config() we had a state
machine that would only set config values if they weren't set already,
and thus by proxy we wouldn't e.g. set "to" based on sendemail.to if
we'd seen sendemail.gmail.to before, with --identity=gmail.

I'd modified some of the relevant code in 3494dfd3ee, but just
reverting to that wouldn't do, since it would bring back the
regression fixed in that commit.

Refactor read_config() do what we actually mean here. We don't want to
set a given sendemail.VAR if a sendemail.$identity.VAR previously set
it. The old code was conflating this desire with the hardcoded
defaults for these variables, and as discussed in 3494dfd3ee that was
never going to work. Instead pass along the state of whether an
identity config set something before, as distinguished from the state
of the default just being false, or the default being a non-bool or
true (e.g. --transferencoding).

I'm still not happy with the test coverage here, e.g. there's nothing
testing sendemail.smtpEncryption, but I only have so much time to fix
this code.

3494dfd3ee send-email: do defaults -> config -> getopt in that order
Change the git-send-email command-line argument parsing and config
reading code to parse those two in the right order. I.e. first we set
our hardcoded defaults, then we read our config, and finally we read
the command-line, with later sets overriding earlier sets.

This fixes a bug introduced in e67a228cd8 ("send-email:
automatically determine transfer-encoding", 2018-07-08). That change
broke the reading of sendmail.transferencoding because it wasn't
careful to update the code to parse them in the previous "defaults
-> getopt -> config" order.

But as we can see from the history for this file doing it this way was
never what we actually wanted, it's just something we grew organically
as of 5483c71d7a ("git-send-email: make options easier to configure.",
2007-06-27) and have been dealing with the fallout since, e.g. in
463b0ea22b ("send-email: Fix %config_path_settings handling",
2011-10-14).

As can be seen in this change the only place where we actually want to
do something clever is with the to/cc/bcc variables, where setting
them on the command-line (or using --no-{to,cc,bcc}) should clear out
values we grab from the config.

All the rest are things where the command-line should simply override
the config values, and by reading the config first the config code
doesn't need all this "let's not set it, if it was on the command-line"
special-casing, as [1] shows we'd otherwise need to care about the
difference between whether something was a default or present in
config to fix the bug in e67a228cd8.

74d76a1701 send-email: default to quoted-printable when CR is present
In 7a36987fff ("send-email: add an auto option for transfer encoding",
2018-07-08), git send-email learned how to automatically determine the
transfer encoding for a patch. However, the only criterion considered
was the length of the lines.

Another case we need to consider is that of carriage returns. Because
emails have CRLF endings when canonicalized, we don't want to write raw
carriage returns into a patch, lest they be stripped off as an artifact
of the transport. Ensure that we choose quoted-printable encoding if the
patch we're sending contains carriage returns.

Note that we are guaranteed to always correctly encode carriage returns
when writing quoted-printable since we explicitly specify the line
ending as "\n", forcing MIME::QuotedPrint to encode our carriage return
as "=0D".

Since commit ef0cc1df90 ("send-email: also pick up cc addresses from

addresses from all *-by lines. As a side effect a line with
'-Signed-off-by' is now also added to cc. This makes send-email pick
lines from patches that remove patch files from the git repo. This is
common in the Buildroot project that often removes (and adds) patch
files that have 'Signed-off-by' in their patch description part.

Consider only *-by lines that start with [a-z] (case insensitive) to
avoid unrelated addresses in cc.

13374987dd completion: use __gitcomp_builtin for format-patch
This helps format-patch gain completion for a couple new options,
notably --range-diff.

Since send-email completion relies on $__git_format_patch_options
which is now reduced, we need to do something not to regress
send-email completion.

The workaround here is implement --git-completion-helper in
send-email.perl just as a bridge to "format-patch --git-completion-helper".
This is enough to use __gitcomp_builtin on send-email (to take
advantage of caching).

In the end, send-email.perl can probably reuse the same info it passes
to GetOptions() to generate full --git-completion-helper output so
that we don't need to keep track of its options in git-completion.bash
anymore. But that's something for another boring day.

It can be necessary to disable SMTP authentication by a mechanism other
than sendemail.smtpuser being undefined. For example, if the user has
sendemail.smtpuser set globally but wants to disable authentication
locally in one repository.

--smtp-auth and sendemail.smtpauth now understand the value 'none' which
means to disable authentication completely, even if an authentication
user is specified.

The value 'none' is lower case to avoid conflicts with any RFC 4422
authentication mechanisms.

The user may also specify the command line argument --no-smtp-auth as a
shorthand for --smtp-auth=none
