Junio C Hamano 6789275d37 tests: teach callers of test_i18ngrep to use test_grep
They are equivalents and the former still exists, so as long as the
only change this commit makes are to rewrite test_i18ngrep to
test_grep, there won't be any new bug, even if there still are
callers of test_i18ngrep remaining in the tree, or when merged to
other topics that add new uses of test_i18ngrep.

This patch was produced more or less with

    git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' |
    xargs perl -p -i -e 's/test_i18ngrep /test_grep /'

and a good way to sanity check the result yourself is to run the
above in a checkout of c4603c1c (test framework: further deprecate
test_i18ngrep, 2023-10-31) and compare the resulting working tree
contents with the result of applying this patch to the same commit.
You'll see that test_i18ngrep in a few t/lib-*.sh files corrected,
in addition to the manual reproduction.

Michael Strawbridge 0d8647034e send-email: move validation code below process_address_list
Move validation logic below processing of email address lists so that
email validation gets the proper email addresses.  As a side effect,
some initialization needed to be moved down.  In order for validation
and the actual email sending to have the same initial state, the
initialized variables that get modified by pre_process_file are
encapsulated in a new function.

This fixes email address validation errors when the optional
perl module Email::Valid is installed and multiple addresses are passed
in on a single to/cc argument like --to=foo@example.com,bar@example.com.
A new test was added to t9001 to expose failures with this case in the
future.

Jeff King 3ec6167567 send-email: handle to/cc/bcc from --compose message
If the user writes a message via --compose, send-email will pick up
various headers like "From", "Subject", etc and use them for other
patches as if they were specified on the command-line. But we don't
handle "To", "Cc", or "Bcc" this way; we just tell the user "those
aren't interpeted yet" and ignore them.

But it seems like an obvious thing to want, especially as the same
feature exists when the cover letter is generated separately by
format-patch. There it is gated behind the --to-cover option, but I
don't think we'd need the same control here; since we generate the
--compose template ourselves based on the existing input, if the user
leaves the lines unchanged then the behavior remains the same.

So let's fill in the implementation; like those other headers we already
handle, we just need to assign to the initial_* variables. The only
difference in this case is that they are arrays, so we'll feed them
through parse_address_line() to split them (just like we would when
reading a single string via prompting).

Jeff King 637e8944a1 Revert "send-email: extract email-parsing code into a subroutine"
This reverts commit b6049542b9.

Prior to that commit, we read the results of the user editing the
"--compose" message in a loop, picking out parts we cared about, and
streaming the result out to a ".final" file. That commit split the
reading/interpreting into two phases; we'd now read into a hash, and
then pick things out of the hash.

The goal was making the code more readable. And in some ways it did,
because the ugly regexes are confined to the reading phase. But it also
introduced several bugs, because now the two phases need to match each
other. In particular:

  - we pick out headers like "Subject: foo" with a case-insensitive
    regex, and then use the user-provided header name as the key in a
    case-sensitive hash. So if the user wrote "subject: foo", we'd no
    longer recognize it as a subject.

  - the namespace for the hash keys conflates header names with meta
    information like "body". If you put "body: foo" in your message, it
    would be misinterpreted as the actual message body (nobody is likely
    to do that in practice, but it seems like an unnecessary danger).

  - the handling for to/cc/bcc is totally broken. The behavior before
    that commit is to recognize and skip those headers, with a note to
    the user that they are not yet handled. Not great, but OK. But
    after the patch, the reading side now splits the addresses into a
    perl array-ref. But the interpreting side doesn't handle this at
    all, and blindly prints the stringified array-ref value. This leads
    to garbage like:

      (mbox) Adding to: ARRAY (0x555b4345c428) from line 'To: ARRAY(0x555b4345c428)'
      error: unable to extract a valid address from: ARRAY (0x555b4345c428)
      What to do with this address? ([q]uit|[d]rop|[e]dit):

    Probably not a huge deal, since nobody should even try to use those
    headers in the first place (since they were not implemented). But
    the new behavior is worse, and indicative of the sorts of problems
    that come from having the two layers.

The revert had a few conflicts, due to later work in this area from
15dc3b9161 (send-email: rename variable for clarity, 2018-03-04) and
d11c943c78 (send-email: support separate Reply-To address, 2018-03-04).
I've ported the changes from those commits over as part of the conflict
resolution.

The new tests show the bugs. Note the use of GIT_SEND_EMAIL_NOTTY in the
second one. Without it, the test is happy to reach outside the test
harness to the developer's actual terminal (when run with the buggy
state before this patch).

Jeff King c016726c2d send-email: avoid creating more than one Term::ReadLine object
Every time git-send-email calls its ask() function to prompt the user,
we call term(), which instantiates a new Term::ReadLine object. But in
v1.46 of Term::ReadLine::Gnu (which provides the Term::ReadLine
interface on some platforms), its constructor refuses to create a second
instance[1]. So on systems with that version of the module, most
git-send-email instances will fail (as we usually prompt for both "to"
and "in-reply-to" unless the user provided them on the command line).

We can fix this by keeping a single instance variable and returning it
for each call to term(). In perl 5.10 and up, we could do that with a
"state" variable. But since we only require 5.008, we'll do it the
old-fashioned way, with a lexical "my" in its own scope.

Note that the tests in t9001 detect this problem as-is, since the
failure mode is for the program to die. But let's also beef up the
"Prompting works" test to check that it correctly handles multiple
inputs (if we had chosen to keep our FakeTerm hack in the previous
commit, then the failure mode would be incorrectly ignoring prompts
after the first).

Junio C Hamano b04671b638 Merge branch 'jc/send-email-pre-process-fix'
When "git send-email" that uses the validate hook is fed a message
without and then with Message-ID, it failed to auto-assign a unique
Message-ID to the former and instead reused the Message-ID from the

Jeff King cfa120947e format-patch: free rev.message_id when exiting
We may allocate a message-id string via gen_message_id(), but we never
free it, causing a small leak. This can be demonstrated by running t9001
with a leak-checking build. The offending test is the one touched by
3ece9bf0f9 (send-email: clear the $message_id after validation,
2023-05-17), but the leak is much older than that. The test was simply
unlucky enough to trigger the leaking code path for the first time.

We can fix this by freeing the string at the end of the function. We can
also re-mark the test script as leak-free, effectively reverting
20bd08aefb (t9001: mark the script as no longer leak checker clean,
2023-05-17).

The test uses "format-patch --thread" which is known to leak the

Plugging these leaks involves straightening out the memory ownership
rules around rev_info.message_id and rev_info.ref_message_ids, and
is beyond the scope of send-email fix, so for now mark the test as
leaky to unblock the topic before the release.

Junio C Hamano 3ece9bf0f9 send-email: clear the $message_id after validation
Recently git-send-email started parsing the same message twice, once
to validate _all_ the message before sending even the first one, and
then after the validation hook is happy and each message gets sent,
to read the contents to find out where to send to etc.

Unfortunately, the effect of reading the messages for validation
lingered even after the validation is done.  Namely $message_id gets
assigned if exists in the input files but the variable is global,
and it is not cleared before pre_process_file runs.  This causes
reading a message without a message-id followed by reading a message
with a message-id to misbehave---the sub reports as if the message
had the same id as the previously written one.

Clear the variable before starting to read the headers in
pre_process_file.

Robin Jarry 3c8d3adeae send-email: export patch counters in validate environment
When sending patch series (with a cover-letter or not)
sendemail-validate is called with every email/patch file independently
from the others. When one of the patches depends on a previous one, it
may not be possible to use this hook in a meaningful way. A hook that
wants to check some property of the whole series needs to know which
patch is the final one.

Expose the current and total number of patches to the hook via the
GIT_SENDEMAIL_PATCH_COUNTER and GIT_SENDEMAIL_PATCH_TOTAL environment
variables so that both incremental and global validation is possible.

Sharing any other state between successive invocations of the validate
hook must be done via external means. For example, by storing it in
a git config sendemail.validateWorktree entry.

Add a sample script with placeholder validations and update tests to
check that the counters are properly exported.

Kyle Meyer 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.

Ævar Arnfjörð Bjarmason 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.

Marvin Häuser 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.

Johannes Sixt f6a5af0f62 t9001: PATH must not use Windows-style paths
On Windows, $(pwd) returns a drive-letter style path C:/foo, while $PWD
contains a POSIX style /c/foo path. When we want to interpolate the
current directory in the PATH variable, we must not use the C:/foo style,
because the meaning of the colon is ambiguous. Use the POSIX style.

Ævar Arnfjörð Bjarmason 2815326f09 send-email: don't needlessly abs_path() the core.hooksPath
In c8243933c7 (git-send-email: Respect core.hooksPath setting,
2021-03-23) we started supporting core.hooksPath in "send-email". It's
been reported that on Windows[1] doing this by calling abs_path()
results in different canonicalizations of the absolute path.

This wasn't an issue in c8243933c7 itself, but was revealed by my
ea7811b37e (git-send-email: improve --validate error output,
2021-04-06) when we started emitting the path to the hook, which was
previously only internal to git-send-email.perl.

The just-landed 53753a37d0 (t9001-send-email.sh: fix expected
absolute paths on Windows, 2021-05-24) narrowly fixed this issue, but
I believe we can do better here. We should not be relying on whatever
changes Perl's abs_path() makes to the path "rev-parse --git-path
hooks" hands to us. Let's instead trust it, and hand it to Perl's
system() in git-send-email.perl. It will handle either a relative or
absolute path.

So let's revert most of 53753a37d0 and just have "hooks_path" return
what we get from "rev-parse" directly without modification. This has
the added benefit of making the error message friendlier in the common
case, we'll no longer print an absolute path for repository-local hook
errors.

Johannes Sixt 53753a37d0 t9001-send-email.sh: fix expected absolute paths on Windows
Git for Windows is a native Windows program that works with native
absolute paths in the drive letter style C:\dir. The auxiliary
infrastructure is based on MSYS2, which uses POSIX style /C/dir.

When we test for output of absolute paths produced by git.exe, we
usally have to expect C:\dir style paths. To produce such expected
paths, we have to use $(pwd) in the test scripts; the alternative,
$PWD, produces a POSIX style path. ($PWD is a shell variable, and the
shell is bash, an MSYS2 program, and operates in the POSIX realm.)

There are two recently added tests that were written to expect C:\dir
paths. The output that is tested is produced by `git send-email`, but
behind the scenes, this is a Perl script, which also works in the
POSIX realm and produces /C/dir style output.

In the first test case that is changed here, replace $(pwd) by $PWD
so that the expected path is constructed using /C/dir style.

The second test case sets core.hooksPath to an absolute path. Since
the test script talks to native git.exe, it is supposed to place a
C:/dir style path into the configuration; therefore, keep $(pwd).
When this configuration value is consumed by the Perl script, it is
transformed to /C/dir style by the MSYS2 layer and echoed back in
this form in the error message. Hence, do use $PWD for the expected
value.

Gregory Anders 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.

Ævar Arnfjörð Bjarmason ea7811b37e git-send-email: improve --validate error output
Improve the output we emit on --validate error to:

 * Say "FILE:LINE" instead of "FILE: LINE", to match "grep -n",
   compiler error messages etc.

 * 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
   that with the system_or_msg() output to say what exit code the hook
   died with.

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.
