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.

Even when running "git send-email" without its own threaded

Fix a regression in my c95e3a3f0b8 (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 1ff750b128e (tests: make
GIT_TEST_GETTEXT_POISON a boolean, 2019-06-21). This test fails
without this bugfix, but now it works.

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.

"git send-email" learned the "--sendmail-cmd" command line option
and the "sendemail.sendmailCmd" configuration variable, which is a

Code simplification.
* ab/send-email-inline-hooks-path:
send-email: move "hooks_path" invocation to git-send-email.perl
send-email: don't needlessly abs_path() the core.hooksPath
|
|
In c8243933c74 (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 c8243933c74 itself, but was revealed by my
ea7811b37e0 (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 53753a37d09 (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 53753a37d09 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.

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.

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.

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.

get-send-email currently makes the assumption that the
'sendemail-validate' hook exists inside of the repository.
Since the introduction of 'core.hooksPath' configuration option in
867ad08a261 (hooks: allow customizing where the hook directory is,
2016-05-04), this is no longer true.
Instead of assuming a hardcoded repo relative path, query
git for the actual path of the hooks directory.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \
t/t1305-config-include.sh t/t1309-early-config.sh \

t/t7508-status.sh t/t7606-merge-custom.sh \
t/t9302-fast-import-unpack-limit.sh
We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\

In the test scripts, the recommended style is, e.g.:
test_expect_success 'name' '
do-something somehow &&
do-some-more testing
'
When using this style, any single quote in the multi-line test section
is actually closing the lone single quotes that surround it.
It can be a non-issue in practice:
test_expect_success 'sed a little' '
sed -e 's/hi/lo/' in >out # "ok": no whitespace in s/hi/lo/
'
Or it can be a bug in the test, e.g., because variable interpolation
happens before the test even begins executing:
v=abc
test_expect_success 'variable interpolation' '
v=def &&
echo '"$v"' # abc
'
Change several such in-test single quotes to use double quotes instead
or, in a few cases, drop them altogether. These were identified using
some crude grepping. We're not fixing any test bugs here, but we're
hopefully making these tests slightly easier to grok and to maintain.
There are legitimate use cases for closing a quote and opening a new
one, e.g., both '\'' and '"'"' can be used to produce a literal single
quote. I'm not touching any of those here.
In t9401, tuck the redirecting ">" to the filename while we're touching
those lines.

|

In this test, we have a command substitution whose output starts with a

does not. As a consequence, zsh fails this test, since the command line
argument we use the variable in is truncated by the NUL byte.
POSIX says of a command substitution that if "the output contains any
null bytes, the behavior is unspecified," so all of the shells are in
compliance with POSIX. To make our code more portable, let's avoid
prefacing our variables with NUL bytes and instead leave only the
trailing one behind.

Since "git send-email" learned to take 'auto' as the value for the
transfer-encoding, it by mistake stopped honoring the values given
to the configuration variables sendemail.transferencoding and/or
sendemail.<ident>.transferencoding. This has been corrected to
(finally) redoing the order of setting the default, reading the

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.

I fixed a bug that had broken the reading of sendmail.transferEncoding
in 3494dfd3ee ("send-email: do defaults -> config -> getopt in that
order", 2019-05-09), but the test I added in that commit did nothing
to assert the bug had been fixed.
That issue originates in 8d81408435 ("git-send-email: add
--transfer-encoding option", 2014-11-25) which first added the
"sendemail.transferencoding=8bit".
That test has never done anything meaningful. It tested that the
"--transfer-encoding=8bit" option would turn on the 8bit
Transfer-Encoding, but that was the default at the time (and now). As
checking out 8d81408435 and editing the test to remove that option
will reveal, supplying it never did anything.
So when I copied it thinking it would work in 3494dfd3ee I copied a
previously broken test, although I was making sure it did the right
thing via da-hoc debugger inspection, so the bug was fixed.
So fix the test I added in 3494dfd3ee, as well as the long-standing
test added in 8d81408435. To test if we're actually setting the
Transfer-Encoding let's set it to 7bit, not 8bit, as 7bit will error
out on "email-using-8bit".
This means that we can remove the "sendemail.transferencoding=7bit
fails on 8bit data" test, since it was redundant, we now have other
tests that assert that that'll fail.
While I'm at it convert "git config <key> <value>" in the test setup
to just "-c <key>=<value>" on the command-line. Then we don't need to
cleanup after these tests, and there's no sense in asserting where
config values come from in these tests, we can take that as a given.

git-send-email for non-threaded mails", 2009-06-12) where the
"$patches" variable was supplied more than once.
As it turns out we didn't need more than one "$patches" for the test
added in 32ae83194b either. The only tests that actually needed this
sort of invocation were the tests added in 54aae5e1a0 ("t9001:
send-email interation with --in-reply-to and --chain-reply-to",
2010-10-19).

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.

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".

This test has been dysfunctional since it was added by 6489660b4b
(send-email: support validate hook, 2017-05-12), however, the problem
went unnoticed due to a broken &&-chain late in the test.
The test wants to verify that a non-zero exit code from the
'sendemail-validate' hook causes git-send-email to abort with a
particular error message. A command which is expected to fail should be
run with 'test_must_fail', however, the test neglects to do so.
Fix this problem, as well as the broken &&-chain behind which the
problem hid.

git send-email, when invoked without a --transfer-encoding option, sends
8bit data without a MIME version or a transfer encoding. This has
several downsides.
First, unless the transfer encoding is specified, it defaults to 7bit,
meaning that non-ASCII data isn't allowed. Second, if lines longer than
998 bytes are used, we will send an message that is invalid according to
RFC 5322. The --validate option, which is the default, catches this
issue, but it isn't clear to many people how to resolve this.
To solve these issues, default the transfer encoding to "auto", so that
we explicitly specify 8bit encoding when lines don't exceed 998 bytes
and quoted-printable otherwise. This means that we now always emit
Content-Transfer-Encoding and MIME-Version headers, so remove the
conditionals from this portion of the code.
It is unlikely that the unconditional inclusion of these two headers
will affect the deliverability of messages in anything but a positive
way, since MIME is already widespread and well understood by most email
programs.

With --validate (which is the default), we warn about lines exceeding
998 characters due to the limits specified in RFC 5322. However, if
we're using a suitable transfer encoding (quoted-printable or base64),
we're guaranteed not to have lines exceeding 76 characters, so there's
no need to fail in this case. The auto transfer encoding handles this
specific case, so accept it as well.

For most patches, using a transfer encoding of 8bit provides good
compatibility with most servers and makes it as easy as possible to view
patches. However, there are some patches for which 8bit is not a valid
encoding: RFC 5322 specifies that a message must not have lines
exceeding 998 octets.
Add a transfer encoding value, auto, which indicates that a patch should
use 8bit where allowed and quoted-printable otherwise. Choose
quoted-printable instead of base64, since base64-encoded plain text is
treated as suspicious by some spam filters.

"git send-email" learned "--reply-to=<address>" option.

send-email: support separate Reply-To address
send-email: rename variable for clarity

In some projects contributions from groups are only accepted from a
common group email address. But every individual may want to receive
replies to her own personal address. That's what we have 'Reply-To'
headers for in SMTP. So introduce an optional '--reply-to' command
line option.
This patch re-uses the $reply_to variable. This could break
out-of-tree patches!
