fb34fe6a24 send-email: only consider lines containing @ or <> for automatic Cc'ing
While the address sanitizations routines do accept local addresses, that
is almost never what is meant in a Cc or Signed-off-by trailer.

Looking through all the signed-off-by lines in the linux kernel tree
without a @, there are mostly two patterns: Either just a full name, or
a full name followed by <user at domain.com> (i.e., with the word at
instead of a @), and minor variations. For cc lines, the same patterns
appear, along with lots of "cc stable" variations that do not actually
name stable@vger.kernel.org

  Cc: stable # introduced pre-git times
  cc: stable.kernel.org

In the <user at domain.com> cases, one gets a chance to interactively
fix it. But when there is no <> pair, it seems we end up just using the
first word as a (local) address.

As the number of cases where a local address really was meant is
likely (and anecdotally) quite small compared to the number of cases
where we end up cc'ing a garbage address, insist on at least a @ or a <>
pair being present.

This is also preparation for the next patch, where we are likely to
encounter even more non-addresses in -by lines, such as

e67a228cd8 send-email: automatically determine transfer-encoding
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.

f2d06fb13f send-email: accept long lines with suitable transfer encoding
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.

7a36987fff send-email: add an auto option for transfer encoding
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.

28654678cf perl: move CPAN loader wrappers to another namespace
Move the Git::Error and Git::Mail::Address wrappers to the
Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That
module will then either load Error from CPAN (if installed on the OS),
or use Git::FromCPAN::Error.

When I added the Error wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think
about how confusing it would be to have these modules sitting in the
same tree as our normal modules. Let's put these all into
Git::{Load,From}CPAN::* to clearly distinguish them from the rest.

This also makes things a bit less confusing since there was already a
Git::Error namespace ever since 8b9150e3e3 ("Git.pm: Handle failed
commands' output", 2006-06-24).

1046c118d8 git-send-email: unconditionally use Net::{SMTP,Domain}
The Net::SMTP and Net::Domain were both first released with perl
v5.7.3[1], since my d48b284183 ("perl: bump the required Perl version
to 5.8 from 5.6.[21]", 2010-09-24) we've depended on 5.8, so there's
no reason to conditionally require them anymore.

This conditional loading was initially added in
87840620fd ("send-email: only 'require' instead of 'use' Net::SMTP",
2006-06-01) for Net::SMTP and 134550fe21 ("git-send-email.perl - try
to give real name of the calling host to HELO/EHLO", 2010-03-14) for
Net::Domain, both of which predate the hard dependency on 5.8.

Since they're guaranteed to be installed now let's "use" them
instead. The cost of loading them both is trivial given what
git-send-email does (~15ms on my system), and it's better to not defer
any potential loading errors until runtime.

This patch is better viewed with -w, which shows that the only change
in the last two hunks is removing the "if eval" wrapper block.

9caa70697b send-email: error out when relogin delay is missing
When the batch size is neither configured nor given on the command
line, but the relogin delay is given, then the current code ignores
the relogin delay setting.

This is unsafe as there was some intention when setting the batch size.
One workaround would be to just assume a batch size of 1 as a default.
This however may be bad UX, as then the user may wonder why it is sending
slowly without apparent batching.

Error out for now instead of potentially confusing the user.
As 5453b83bdf (send-email: --batch-size to work around some SMTP
server limit, 2017-05-21) lays out, we rather want to not have this
interface anyway and would rather want to react on the server throttling
dynamically.

bd869f67b9 send-email: add and use a local copy of Mail::Address
We used to have two versions of the email parsing code. Our
parse_mailboxes (in Git.pm), and Mail::Address which we used if
installed. Unfortunately, both versions have different sets of bugs, and
changing the behavior of git depending on whether Mail::Address is
installed was a bad idea.

A first attempt to solve this was cc90750 (send-email: don't use
Mail::Address, even if available, 2017-08-23), but it turns out our
parse_mailboxes is too buggy for some uses. For example the lack of
nested comments support breaks get_maintainer.pl in the Linux kernel
tree:

  https://public-inbox.org/git/20171116154814.23785-1-alex.bennee@linaro.org/

This patch goes the other way: use Mail::Address anyway, but have a
local copy from CPAN as a fallback, when the system one is not
available.

The duplicated script is small (276 lines of code) and stable in time.
Maintaining the local copy should not be an issue, and will certainly be
less burden than maintaining our own parse_mailboxes.

Another option would be to consider Mail::Address as a hard dependency,
but it's easy enough to save the trouble of extra-dependency to the end
user or packager.

b6049542b9 send-email: extract email-parsing code into a subroutine
The existing code mixes parsing of email header with regular
expression and actual code. Extract the parsing code into a new
subroutine "parse_header_line()". This improves the code readability
and make parse_header_line reusable in other place.

"parsed_header_line()" and "filter_body()" could be used for
refactoring the part of code which parses the header to prepare the
email and send it.

In contrast to the previous version it doesn't keep the header order
and strip duplicate headers.

20d2a30f8f Makefile: replace perl/Makefile.PL with simple make rules
Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].

The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.

We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].

There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.

So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").

While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.

Functional changes:

 * This will not always install into perl's idea of its global
   "installsitelib". This only potentially matters for packagers that
   need to expose Git.pm for non-git use, and as explained in the
   INSTALL file there's a trivial workaround.

 * The scripts themselves will 'use lib' the target directory, but if
   INSTLIBDIR is set it overrides it. It doesn't have to be this way,
   it could be set in addition to INSTLIBDIR, but my reading of [7] is
   that this is the desired behavior.

 * We don't build man pages for all of the perl modules as we used to,
   only Git(3pm). As discussed on-list[8] that we were building
   installed manpages for purely internal APIs like Git::I18N or
   private-Error.pm was always a bug anyway, and all the Git::SVN::*
   ones say they're internal APIs.

   There are apparently external users of Git.pm, but I don't expect
   there to be any of the others.

   As a side-effect of these general changes the perl documentation
   now only installed by install-{doc,man}, not a mere "install" as
   before.

_if available_ causes much more trouble than it gives benefits:

* Developers typically test one version, not both.

* Users may not be aware that installing Mail::Address will change the
  behavior. They may complain about the behavior in one case without
  knowing that Mail::Address is involved.

* Having this optional Mail::Address makes it tempting to anwser "please

cb2922fe4b send-email: fix garbage removal after address
This is a followup over 9d33439 (send-email: only allow one address
per body tag, 2017-02-20). The first iteration did allow writting

  Cc: <foo@example.com> # garbage

but did so by matching the regex ([^>]*>?), i.e. stop after the first
instance of '>'. However, it did not properly deal with

  Cc: foo@example.com # garbage

Fix this using a new function strip_garbage_one_address, which does
essentially what the old ([^>]*>?) was doing, but dealing with more
corner-cases. Since we've allowed

  Cc: "Foo # Bar" <foobar@example.com>

in previous versions, it makes sense to continue allowing it (but we
still remove any garbage after it). OTOH, when an address is given
without quoting, we just take the first word and ignore everything
after.

Some email servers (e.g. smtp.163.com) limit the number emails to be

sending many messages.

Teach send-email to disconnect after sending a number of messages

reconnect, to work around such a limit.

Also add two configuration variables to give these options the default.

Note:

  We will use this as a band-aid for now, but in the longer term, we
  should look at and react to the SMTP error code from the server;

  servers.

9d3343961b send-email: only allow one address per body tag
Adding comments after a tag in the body is a common practise (e.g. in
the Linux kernel) and git-send-email has been supporting this for years
by removing any trailing cruft after the address.

After some recent changes, any trailing comment is now instead appended
to the recipient name (with some random white space inserted) resulting
in undesirable noise in the headers, for example:

CC: "# 3 . 3 . x : 1b9508f : sched : Rate-limit newidle" <stable@vger.kernel.org>

Revert to the earlier behaviour of discarding anything after the (first)
address in a tag while parsing the body.

Note that multiple addresses after are still allowed after a command
line switch (and in a CC header field).

Also note that --suppress-cc=self was never honoured when using multiple
addresses in a tag.

531220ba50 send-email: detect and offer to skip backup files
Diligent people save output from format-patch to files, proofread
and edit them and then finally send the result out.  If the
resulting files are sent out with "git send-email 0*", this ends up
sending backup files (e.g. 0001-X.patch.backup or 0001-X.patch~)
left by their editors next to the final version.  Sending them with
"git send-email 0*.patch" (if format-patch was run with the standard
suffix) would avoid such an embarrassment, but not everybody is
careful.

After collecting files to be sent (and sorting them if read from a
directory), notice when the file being sent out has the same name as
the previous file, plus some suffix (e.g. 0001-X.patch was sent, and
we are looking at 0001-X.patch.backup or 0001-X.patch~), and the
suffix begins with a non-alnum (e.g. ".backup" or "~") and ask if
the user really wants to send it out.  Once the user skips sending
such a "backup" file, remember the suffix and stop asking the same
question (e.g. after skipping 0001-X.patch~, skip 0002-Y.patch~
without asking).

f916ab0ccc send-email: more meaningful Message-ID
Using a YYYYmmddHHMMSS date representation is more meaningful to
humans, especially when used for lookups on NNTP servers or linking
to archive sites via Message-ID (e.g. mid.gmane.org or
mid.mail-archive.com).  This timestamp format more easily gives a
reader of the URL itself a rough date of a linked message compared
to having them calculate the seconds since the Unix epoch.

Furthermore, having the MUA name in the Message-ID seems to be a
rare oddity I haven't noticed outside of git-send-email.  We
already have an optional X-Mailer header field to advertise for
us, so extending the Message-ID by 15 characters can make for
unpleasant Message-ID-based URLs to archive sites.

a277d1efa3 send-email: ignore trailing whitespace in mailrc alias file
The regex for parsing mailrc considers everything after the
second whitespace to be the email address, up to the end of
the line. We have to include whitespace there, because you
may have multiple space-separated addresses, each with their
own internal quoting.

But if there is trailing whitespace, we include that, too.
This confuses quotewords() when we try to split the
individual addresses, and we end up storing "undef" in our
alias list. Later parts of the code then access that,
generating perl warnings.

Let's tweak our regex to throw away any trailing whitespace
on each line.

	Unable to initialize SMTP properly. Check config and use --smtp-debug.

but adding --smtp-debug=1 just produces the same output since we don't

Turning on SSL debug at level 1 gives:

	DEBUG: .../IO/Socket/SSL.pm:1796: SSL connect attempt failed error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
	DEBUG: .../IO/Socket/SSL.pm:673: fatal SSL error: SSL connect attempt failed error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
	DEBUG: .../IO/Socket/SSL.pm:1780: IO::Socket::IP configuration failed

IO::Socket::SSL defines level 1 debug as "print out errors from
IO::Socket::SSL and ciphers from Net::SSLeay".  In fact, it aliases
Net::SSLeay::trace which is defined to guarantee silence at level 0 and
only emit error messages at level 1, so let's enable it by default.

is the bash-completion script which will use it to autocomplete aliases
on the options which take addresses.

Add some tests for the new option using various alias file formats.

A possible future extension to the alias dump format could be done by

format to display. This has not been done in this patch as no user of

Since the help only mentions the 'no-' prefix and not the 'no'

older GetOptions versions.

852a15d748 send-email: ask confirmation if given encoding name is very short
Sometimes people respond "y<ENTER>" (or "yes<ENTER>") when asked
this question:

    Which 8bit encoding should I declare [UTF-8]?

We already have a mechanism to avoid accepting a mistyped e-mail
address (we ask to confirm when the given address lacks "@" in it);
reuse it to trigger the same confirmation when given a very short
answer.  As a typical charset name is probably at least 4 chars or
longer (e.g. "UTF8" spelled without the dash, or "Big5"), this would
prevent such a mistake.

* Share regexes between unquote_rfc2047 and is_rfc2047_quoted. Besides
  removing duplication, this also makes unquote_rfc2047 more stringent.

* Allow both "q" and "Q" to identify the encoding.

* Allow lowercase hexadecimal digits in the "Q" encoding.

And, more on the cosmetic side:

* Change the "encoded-text" regex to exclude rather than include characters,
  for clarity and consistency with "token".

8d81408435 git-send-email: add --transfer-encoding option
The thread at http://thread.gmane.org/gmane.comp.version-control.git/257392
details problems when applying patches with "git am" in a repository with
CRLF line endings.  In the example in the thread, the repository originated
from "git-svn" so it is not possible to use core.eol and friends on it.

Right now, the best option is to use "git am --keep-cr".  However, when
a patch create new files, the patch application process will reject the
new file because it finds a "/dev/null\r" string instead of "/dev/null".

The problem is that SMTP transport is CRLF-unsafe.  Sending a patch by
email is the same as passing it through "dos2unix | unix2dos".  The newly
introduced CRLFs are normally transparent because git-am strips them. The
keepcr=true setting preserves them, but it is mostly working by chance
and it would be very problematic to have a "git am" workflow in a
repository with mixed LF and CRLF line endings.

The MIME solution to this is the quoted-printable transfer enconding.
This is not something that we want to enable by default, since it makes
received emails horrible to look at.  However, it is a very good match
for projects that store CRLF line endings in the repository.

The only disadvantage of quoted-printable is that quoted-printable
patches fail to apply if the maintainer uses "git am --keep-cr".  This
is because the decoded patch will have two carriage returns at the end
of the line.  Therefore, add support for base64 transfer encoding too,
which makes received emails downright impossible to look at outside
a MUA, but really just works.

The patch covers all bases, including users that still live in the late
80s, by also providing a 7bit content transfer encoding that refuses
to send emails with non-ASCII character in them.  And finally, "8bit"
will add a Content-Transfer-Encoding header but otherwise do nothing.

On Windows, absolute paths might start with a DOS drive prefix,
which these two checks failed to recognize.

Unfortunately, we cannot simply use the file_name_is_absolute
helper in File::Spec::Functions, because Git for Windows has an
MSYS-based Perl, where this helper doesn't grok DOS
drive-prefixes.

So let's manually check for these in that case, and fall back to
the File::Spec-helper on other platforms (e.g Win32 with native
Perl)
