Teach send-email to read aliases in the sendmail aliases format, i.e.

	<alias>: <address|alias>[, <address|alias>...]

Examples:

	alice: Alice W Land <awol@example.com>
	bob: Robert Bobbyton <bob@example.com>
	# this is a comment
	   # this is also a comment
	chloe: chloe@example.com
	abgroup: alice, bob
	bcgrp: bob, chloe, Other <o@example.com>

 - Quoted aliases and quoted addresses are not supported.
 - Line continuations are not supported.

Warnings are printed for explicitly unsupported constructs, and any
other lines that are not matched by the parser.

Only Perl version 5.8.0 or later is required, but that comes with

older GetOptions versions.

Junio C Hamano 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.

Paolo Bonzini 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

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)

verification in such a case.

Ruben Kerkhof 01645b7493 send-email: /etc/ssl/certs/ directory may not be usable as ca_path
When sending patches on Fedora rawhide with
git-1.8.5.2-1.fc21.x86_64 and perl-IO-Socket-SSL-1.962-1.fc21.noarch,
with the following

    [sendemail]
	    smtpencryption = tls
	    smtpserver = smtp.gmail.com
	    smtpuser = ruben@rubenkerkhof.com
	    smtpserverport = 587

git-send-email fails with:

    STARTTLS failed! SSL connect attempt failed with unknown error
    error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate
    verify failed at /usr/libexec/git-core/git-send-email line 1236.

The current code detects the presence of /etc/ssl/certs directory
(it actually is a symlink to another directory, but that does not
matter) and uses SSL_ca_path to point at it when initializing the
connection with IO::Socket::SSL or Net::SMTP::SSL.  However, on the
said platform, it seems that this directory is not designed to be
used as SSL_ca_path.  Using a single file inside that directory
(cert.pem, which is a Mozilla CA bundle) with SSL_ca_file does work,
and also not specifying any SSL_ca_file/SSL_ca_path (and letting the
library use its own default) and asking for peer verification does
work.

By removing the code that blindly defaults $smtp_ssl_cert_path to
"/etc/ssl/certs", we can prevent the codepath that treats any
directory specified with that variable as usable for SSL_ca_path
from incorrectly triggering.

This change could introduce a regression for people on a platform
whose certificate directory is /etc/ssl/certs but its IO::Socket:SSL
somehow fails to use it as SSL_ca_path without being told.  Using
/etc/ssl/certs directory as SSL_ca_path by default like the current
code does would have been hiding such a broken installation without
its user needing to do anything.  These users can still work around
such a platform bug by setting the configuration variable explicitly
to point at /etc/ssl/certs.

This change should not negate what 35035bbf (send-email: be explicit
with SSL certificate verification, 2013-07-18), which was the
original change that introduced the defaulting to /etc/ssl/certs/,
attempted to do, which is to make sure we do not communicate over
insecure connection by default, triggering warning from the library.

Thomas Rast 5508f3ed2c send-email: set SSL options through IO::Socket::SSL::set_client_defaults
When --smtp-encryption=ssl, we use a Net::SMTP::SSL connection,
passing its ->new all the options that would otherwise go to
Net::SMTP->new (most options) and IO::Socket::SSL->start_SSL (for the
SSL options).

However, while Net::SMTP::SSL replaces the underlying socket class
with an SSL socket, it does nothing to allow passing options to that
socket.  So the SSL-relevant options are lost.

Fortunately there is an escape hatch: we can directly set the options
with IO::Socket::SSL::set_client_defaults.  They will then persist
within the IO::Socket::SSL module.

Ramkumar Ramachandra 35035bbf07 send-email: be explicit with SSL certificate verification
When initiating an SSL connection without explicitly specifying the
SSL certificate verification mode, Net::SMTP::SSL defaults to no
verification, but recent versions of the module gives a warning
against this use of the default.

Enable certificate verification by default, using /etc/ssl/certs as
the default path for certificates of certificate authorities.  This
path can be overriden by the --smtp-ssl-cert-path command line
option and the sendemail.smtpSSLCertPath configuration variable.

Passing an empty string as the path for CA certificates path disables
the SSL certificate verification explicitly, which does not trigger
the warning from recent versions of Net::SMTP::SSL.

to avoid shell from expanding metacharacters in $file, but we do
expect multi-word string in $to_cmd and $cc_cmd to be expanded by
the shell, so we cannot rewrite it to

	open my $fh, "-|", $cmd, $file;

for extra safety.  At least, by using this in the three-arg form:

we can silence Perlcritic, even though we do not gain much safety by

both of which expects to pass a single scalar variable and see if

defined with a function prototype ($) to force a scalar context
while evaluating the arguments at the calling site but it does not
help the current calling sites.  The only effect it has is to hurt
future calling sites that may want to build an argument list in an
array variable and call it as check_file_rev_confict(@args).

Ramkumar Ramachandra 622bc93091 send-email: use "return;" not "return undef;" on error codepaths
All the callers of "ask", "extract_valid_address", and "validate_patch"
subroutines assign the return values from them to a single scalar:

	$var = subr(...);

and "return undef;" in these subroutine can safely be turned into a
simpler "return;".  Doing so will also future-proof a new caller that
mistakenly does this:

    @foo = ask(...);
    if (@foo) { ... we got an answer ... } else { ... we did not ... }

Note that we leave "return undef;" in validate_address on purpose,
even though Perlcritic may complain.  The primary "return" site of
the function returns whatever is in the scalar variable $address, so
it is pointless to change only the other "return undef;" to "return".
The caller must be prepared to see an array with a single undef as
the return value from this subroutine anyway.

If smtp_user is provided but smtp_pass is not, instead of
prompting for password, make git-send-email use git

Junio C Hamano 94383a8135 Merge branch 'nz/send-email-headers-are-case-insensitive'
When user spells "cc:" in lowercase in the fake "header" in the
trailer part, send-email failed to pick up the addresses from
there. As e-mail headers field names are case insensitive, this
script should follow suit and treat "cc:" and "Cc:" the same way.

Nickolai Zeldovich 6310071abf git-send-email: treat field names as case-insensitively
Field names like To:, Cc:, etc. are case-insensitive; use a
case-insensitive regexp to match them as such.

Previously, git-send-email would fail to pick-up the addresses when
in-body "fake" headers with different cases (e.g. lowercase "cc:")
are manually inserted to the messages it was asked to send, even
though the text will still show them.

Krzysztof Mazur 5c80afed02 git-send-email: ask what to do with an invalid email address
We used to warn about invalid emails and just drop them. Such warnings
can be unnoticed by user or noticed after sending email when we are not
giving the "final sanity check [Y/n]?"

Now we quit by default.

Krzysztof Mazur e431225569 git-send-email: remove invalid addresses earlier
Some addresses are passed twice to unique_email_list() and invalid addresses
may be reported twice per send_message. Now we warn about them earlier
and we also remove invalid addresses.

This also removes using of undefined values for string comparison
for invalid addresses in cc list processing.

Felipe Contreras 8cac13dccb send-email: avoid questions when user has an ident
Currently we keep getting questions even when the user has properly
configured his full name and password:

  Who should the emails appear to be from?
  [Felipe Contreras <felipe.contreras@gmail.com>]

And once a question pops up, other questions are turned on. This is
annoying.

The reason it's safe to avoid this question is because currently the
script fails completely when the author (or committer) is not correct,
so we won't even be reaching this point in the code.

The scenarios, and the current situation:

1) No information at all, no fully qualified domain name

  fatal: empty ident name (for <felipec@nysa.(none)>) not allowed

2) Only full name

  fatal: unable to auto-detect email address (got 'felipec@nysa.(none)')

3) Full name + fqdm

  Who should the emails appear to be from?
  [Felipe Contreras <felipec@nysa.felipec.org>]

4) Full name + EMAIL

  Who should the emails appear to be from?
  [Felipe Contreras <felipe.contreras@gmail.com>]

5) User configured
6) GIT_COMMITTER
7) GIT_AUTHOR

All these are the same as 4)

After this patch:

1) 2) won't change: git send-email would still die

4) 5) 6) 7) will change: git send-email won't ask the user

This is good, that's what we would expect, because the identity is
explicit.

3) will change: git send-email won't ask the user

This is bad, because we will try with an address such as
'felipec@nysa.felipec.org', which is most likely not what the user
wants, but the user will get warned by default (confirm=auto), and if
not, most likely the sending won't work, which the user would readily
note and fix.

The worst possible scenario is that such mail address does work, and the
user sends an email from that address unintentionally, when in fact the
user expected to correct that address in the prompt. This is a very,
very, very unlikely scenario, with many dependencies:

1) No configured user.name/user.email
2) No specified $EMAIL
3) No configured sendemail.from
4) No specified --from argument
5) A fully qualified domain name
6) A full name in the geckos field
7) A sendmail configuration that allows sending from this domain name
8) confirm=never, or
8.1) confirm configuration not hitting, or
8.2) Getting the error, not being aware of it
9) The user expecting to correct this address in the prompt

In a more likely scenario where 7) is not the case (can't send from
nysa.felipec.org), the user will simply see the mail was not sent
properly, and fix the problem.

The much more likely scenario though, is where 5) is not the case
(nysa.(none)), and git send-email will fail right away like it does now.

So the likelihood of this affecting anybody seriously is very very slim,
and the chances of this affecting somebody slightly are still very
small. The vast majority, if not all, of git users won't be affected
negatively, and a lot will benefit from this.

Krzysztof Mazur 95c0d4b68a git-send-email: fix fallback code in extract_valid_address()
In the fallback check, used when Email::Valid is not available, the
extract_valid_address() uses $1 without checking for success of matching
regex. The $1 variable may still hold the result of previous match,
which is the address when email address was in '<>' or be undefined
otherwise.

Now if match fails undefined value is always returned to indicate error.
The same value is used by Email::Valid->address() in that case.

Previously 'foo@bar' address was rejected by Email::Valid and fallback,
but '<foo@bar>' was rejected by Email::Valid, but accepted by fallback.
