"netrc" credential helper has been improved to understand textual
service names (like smtp) in addition to the numeric port numbers
(like 25).
* mc/netrc-service-names:
contrib: better support symbolic port names in git-credential-netrc
contrib: warn for invalid netrc file ports in git-credential-netrc
contrib: use a more portable shebang for git-credential-netrc
|
|
To improve support for symbolic port names in netrc files, this
changes does the following:
- Treat symbolic port names as ports, not protocols in git-credential-netrc
- Validate the SMTP server port provided to send-email
- Convert the above symbolic port names to their numerical values.
Before this change, it was not possible to have a SMTP server port set
to "smtps" in a netrc file (e.g. Emacs' ~/.authinfo.gpg), as it would
be registered as a protocol and break the match for a "smtp" protocol
host, as queried for by git-send-email.

Whenever an email is sent, send-email shows a log at last, which
contains all the headers of the email that were received by the
receipients.
In case outlook changes the Message-ID, a log for the same is shown to
the user, but that change is not reflected when the log containing all
the headers is displayed. Here is an example of the log that is shown
when outlook changes the Message-ID:
Outlook reassigned Message-ID to: <PN3PR01MB95973E5ACD7CCFADCB4E298CB865A@PN3PR01MB9597.INDPRD01.PROD.OUTLOOK.COM>

Fix this by updating the $header variable, which has the message ID we
internally assigned on the "Message-ID:" header, with the message ID the
Outlook server assigned. It should look like this after this patch:

Whenever we send a thread of emails using send-email, a message number
is internally assigned to each email. This number is used to track the
order of the emails in the thread. Whenever a new message is processed
in a thread, the current script logic increments the message number by
one, which is intended.
But, if a message is edited and then resent, its message number again
gets incremented. This is because the script uses the same logic to
process the edited message, which it uses to send the next message.
This minor bug is usually harmless, unless a special situations arises.
That situation is when the first message in a thread is edited and
resent, and an `--in-reply-to` argument is also passed to send-email.
In this case, if the user has chosen shallow threading, the threading
does not work as expected, and all messages become replies to the
Message-ID specified in the `--in-reply-to` argument.
The reason for this bug is hidden in the code for threading itself.
if ($thread) {
if ($message_was_sent &&
($chain_reply_to || !defined $in_reply_to || length($in_reply_to) == 0 ||
$message_num == 1)) {
$in_reply_to = $message_id;
if (length $references > 0) {
$references .= "\n $message_id";
} else {
$references = "$message_id";
}
}
}
Here `$message_num` is the current message number, and `$in_reply_to` is
the Message-ID of the message to which the current message is a reply.
In case `--in-reply-to` is specified, the `$in_reply_to` variable
is set to the value of the `--in-reply-to` argument.
Whenever this whole set of conditions is true, the script sets the
`$in_reply_to` variable to the current message's ID. This is done to
ensure that the next message in the thread is a reply to this message.
In case we specify an `--in-reply-to` argument, and have shallow
threading, the only condition that can make this true is
`$message_num == 1`, which is true for the first message in a thread.
Thus, the `$in_reply_to` variable gets set to the first message's ID.
For subsequent messages, the `$message_num` variable is always
greater than 1, and the whole set of conditions is false. Therefore, the
`$in_reply_to` variable remains as the first message's ID. This is what
we expect in shallow threading. But if the user edits the first message
and resends it, the `$message_num` variable gets incremented by 1, and
thus the condition `$message_num == 1` becomes false. This means that
the `$in_reply_to` variable is not set to the first message's ID. As a
result the next message in the thread is not a reply to the first
message, but to the `--in-reply-to` argument, effectively breaking the
threading.
In case the user does not specify an `--in-reply-to` argument, the
`!defined $in_reply_to` condition is true, and thus the `$in_reply_to`
variable is set to the first message's ID, and the threading works
as expected, regardless of the message number.
To fix this bug, we need to ensure that the `$message_num` variable is
not incremented by 1 when a message is edited and resent. We do this by
decreasing the `$message_num` variable by 1 whenever the request to edit
a message is received. This way, the next message in the thread will
have the same message number as the edited message. Therefore the
threading will work as expected.
The same logic has also been applied in case the user drops a single
message from the thread by choosing the "[n]o" option during
confirmation. By doing this, the next message in the thread is assigned
the message number of the dropped message, and thus the threading
works as expected.

Teach "git send-email" to also consult `hostname -f` for mail
domain to compute the identity given to SMTP servers.

`hostname` is a popular command available on both Linux and macOS. As
per the man-page[1], `hostname -f` command returns the fully qualified
domain name (FQDN) of the system. The current Net::Domain perl module
being used in the script for the same has been quite unrealiable in many
cases. Thankfully, we now have a better check for valid_fqdn, which does
reject the invalid FQDNs given by this module properly, but at the same
time, it will result in a fallback to 'localhost.localdomain' being
used. `hostname -f` has been quite reliable (probably even more reliable
than the Net::Domain module) and before falling back to
'localhost.localdomain', we should try to use it. Interestingly, the
`hostname` command is actually used by perl modules like Net::Domain[2]
and Sys::Hostname[3] to get the hostname. So, lets give `hostname -f` a
chance as well!

The current implementation of a valid Fully Qualified Domain Name
is not that strict. It just checks whether it has a dot (.) and
if using macOS, it should not end with .local. As per RFC1035[1],
from what I understood, the following checks need to be done:
- The domain must contain atleast one dot
- Each label (separated by dots) must be 1-63 characters long
- Labels must start and end with an alphanumeric character
- Labels can contain alphanumeric characters and hyphens
Here are some examples of valid and invalid labels:
'example.com', # Valid
'sub.example.com', # Valid
'my-domain.org', # Valid
'localhost', # Invalid (no dot)
'MacBook..', # Invalid (double dots)
'-example.com', # Invalid (starts with a hyphen)
'example-.com', # Invalid (ends with a hyphen)
'example..com', # Invalid (double dots)
'example', # Invalid (no TLD)
'example.local', # Invalid on macOS
'valid-domain.co.uk', # Valid
'123.example.com', # Valid
'example.com.', # Invalid (trailing dot)
'toolonglabeltoolonglabeltoolonglabeltoolonglabeltoolonglabeltoolonglabel.com', # Invalid (label > 63 chars)
Due to current implementation, I was not able to send emails from
Ubuntu. Upon debugging, I found that the SMTP domain being passed
to Outlook's servers was not valid.
Net::SMTP=GLOB(0x5db4351225f8)>>> EHLO MacBook..
Net::SMTP=GLOB(0x5db4351225f8)<<< 501 5.5.4 Invalid domain name
Net::SMTP=GLOB(0x5db4351225f8)>>> HELO MacBook..
Notice that an invalid domain name "MacBook.." is sent by git-send-email.
We have a fallback code that checks output from Net::Domain::domainname()
or asking domain method of an Net::SMTP instance to detect a misconfigured
hostname and replace it with fallback "localhost.localdomain", but the
valid_fqdn apparently is failing to say "MacBook.." is not a valid fqdn.
With this patch, the rule used in valid_fqdn is tightened, the beginning
part of the SMTP exchange looked like this:
Net::SMTP=GLOB(0x58c8af71e930)>>> EHLO localhost.localdomain
Net::SMTP=GLOB(0x58c8af71e930)<<< 250-PN4P287CA0064.outlook.office365.com Hello

Add an option to allow users to specifically enable or disable
retrieving the Message-ID from the Outlook SMTP server. This can be used
for other hosts mimicking the behaviour of Outlook, or for users who set
a custom domain to be a CNAME for the Outlook SMTP server.

The script generates a Message-ID alongwith the other headers when
gen_header is called, and is sent alongwith the email. For most email
providers, including gmail, the Message-ID goes unchanged to the
recipient.
But, this does not seem to be a case with Outlook. In Outlook, when we
send our own Message-ID as a part of the headers, it discards it. Then
it generates a new random Message-ID and that is what the recipient
gets.
This is a problem because the Message-ID is crucial when we are sending
multiple emails in a thread. The current implementation for threads in
the script replies to the Message-ID it generated, but due to Outlook's
behavior, it is not the same as the one that the recipient got, thus
breaking threads. So a need arises to retrieve the Message-ID from the
server response and set it in the In-Reply-To and References email
headers instead of using the self generated one for the purpose of
replies.
The $smtp->message variable in this script for outlook is something like
this:
2.0.0 OK <Message-ID> [Hostname=Some-hostname]
The Message-ID here is the one the recipient gets, rather than the one
the script generated.
This patch uses the fact above and retrieves the Message-ID from the
server response. It then changes the value of the $message_id variable
to the one received from the server. This value will be used when next
and subsequent messages are sent as replies to the message, thus
preserving the threading of the messages.

Code captured errors but did not process them further.
This treated all failures the same without distinguishing SMTP status.
Add handle-smtp_error to extract SMTP status codes using a regex (as
defined in RFC 5321) and handle errors as follows:
- No error present:
- If a result is provided, return 1 to indicate success.
- Otherwise, return 0 to indicate failure.
- Error present with a captured three-digit status code:
- For 4yz (transient errors), return 1 and allow retries.
- For 5yz (permanent errors), return 0 to indicate failure.
- For any other recognized status code, return 1, treating it as
a transient error.
- Error present but no status code found:
- Return 1 as a transient error.

Auth relied solely on return values without catching errors. This misjudges
non-credential errors as auth failure without error info.
Patch wraps the entire auth process in an eval {} block to catch
all exceptions, including non-credential errors. It adds a new $error var,
uses 'or do' to prevent flow break, and returns $result ? 1 : 0. And merges
if/else branches, integrates SASL and basic auth, with comments for

We have a bunch of placeholders in our scripts that we replace at build
time, for example by using sed(1). These placeholders come in three
different formats: @PLACEHOLDER@, @@PLACEHOLDER@@ and ++PLACEHOLDER++.
Next to being inconsistent it also creates a bit of a problem with
CMake, which only supports the first syntax in its `configure_file()`
function. To work around that we instead manually replace placeholders
via string operations, which is a hassle and removes safeguards that
CMake has to verify that we didn't forget to replace any placeholders.
Besides that, other build systems like Meson also support the CMake
syntax.
Unify our codebase to consistently use the syntax supported by such
build systems.

Our platform support policy states that we require "versions of
dependencies which are generally accepted as stable and supportable,
e.g., in line with the version used by other long-term-support
distributions". Of Debian, Ubuntu, RHEL, and SLES, the four most common
distributions that provide LTS versions, the version with mainstream
long-term security support with the oldest Perl is 5.26.0 in SLES 15.6.
This is a major upgrade, since Perl 5.8.1, according to the Perl
documentation, was released in September of 2003. It brings a lot of
new features that we can choose to use, such as s///r to return the
modified string, the postderef functionality, and subroutine signatures,
although the latter was still considered experimental until 5.36.
This change was made with the following one-liner, which intentionally
excludes modifying the vendored modules we include to avoid conflicts:
git grep -l 'use 5.008001' | grep -v 'LoadCPAN/' | xargs perl -pi -e 's/use 5.008001/require v5.26/'
Use require instead of use to avoid changing the behavior as the latter
enables features and the former does not.

"git send-email" learned "--mailmap" option to allow rewriting the
recipient addresses.

In some cases, a user may be generating a patch for an old commit which
now has an out-of-date author or other identity. For example, consider a
team member who contributes to an internal fork of an upstream project,
but leaves before this change is submitted upstream.
In this case, the team members company address may no longer be valid,
and will thus bounce when sending email.
This can be manually avoided by editing the generated patch files, or by
carefully using --suppress-<cc|to> options. This requires a lot of
manual intervention and is easy to forget.
Git has support for mapping old email addresses and names to a canonical
name and address via the .mailmap file (and its associated mailmap.file,
mailmap.blob, and log.mailmap options).
Teach git send-email to enable mailmap support for all addresses. This
ensures that addresses point to the canonical real name and email
address.
Add the sendemail.mailmap configuration option and its associated
--mailmap (and --use-mailmap for compatibility with git log) options.
For now, the default behavior is to disable the mailmap in order to
avoid any surprises or breaking any existing setups.
These options support per-identity configuration via the
sendemail.identity configuration blocks. This enables identity-specific
configuration in cases where users may not want to enable support.
In addition, support send-email specific mailmap data via
sendemail.mailmap.file, sendemail.mailmap.blob and their
identity-specific variants.
The intention of these options is to enable mapping addresses which are
no longer valid to a current project or team maintainer. Such mappings
may change the actual person being referred to, and may not make sense
in a traditional mailmap file which is intended for updating canonical
name and address for the same individual.

git send-email has support for converting shorthand alias names to
canonical email addresses via the alias file. It supports a wide variety
of alias file formats based on popular email program file formats.
Other programs, such as b4, would like the ability to convert aliases in
the same way as git send-email without needing to re-implement the logic
for understanding the many file formats.
Teach git send-email a new option, --translate-aliases, which will
enable this functionality. Similar to --dump-aliases, this option works
like a new mode of operation for git send-email.
When run with --translate-aliases, git send-email reads from standard
input and converts any provided alias into its canonical name and email
according to the alias file. Each expanded name and address is printed
to standard output, one per line.

Address-looking strings found on the trailer are now placed on the

* cb/send-email-sanitize-trailer-addresses:
git-send-email: use sanitized address when reading mbox body
|

Addresses that are mentioned on the trailers in the commit log
messages (e.g., "Reviewed-by") are added to the "Cc:" list by "git
send-email". These hand-written addresses, however, may be
malformed (e.g., having unquoted "." and other punctutation marks in
the display-name part) and can upset MTA.
The code does use the sanitize_address() helper on these
address-looking strings to turn them into valid addresses, but it is
used only to see if the address should be suppressed. The original
string taken from the message is added to the @cc list if the code
decides the address is not suppressed.
Because the addresses on trailer lines are hand-written and more
likely to contain malformed addresses, when adding to the @cc list,
use the result from sanitize_address, not the original. Note that
we do not modify the behaviour for addresses taken from the e-mail
headers, as they are more likely to be machine generated and
well-formed.

Getopt::Long 2.33 added support for the '--no-' prefix natively by
appending '!' to the option specification string, which was included in

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.

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).

This reverts commit b6049542b97e7b135e0e82bf996084d461224d32.
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).

When validating email addresses with `extract_valid_address_or_die()`,
we print out a helpful error message when the given input does not
contain a valid email address.
However, the pre-image of this patch looks something like:
my $address = shift;
$address = extract_valid_address($address):
die sprintf(__("..."), $address) if !$address;
which fails when given a bogus email address by trying to use $address
(which is undef) in a sprintf() expansion, like so:
$ git.compile send-email --to="pi <pi@pi>" /tmp/x/*.patch --force
Use of uninitialized value $address in sprintf at /home/ttaylorr/src/git/git-send-email line 1175.
error: unable to extract a valid address from:
This regression dates back to e431225569 (git-send-email: remove invalid
addresses earlier, 2012-11-22), but became more noticeable in a8022c5f7b
(send-email: expose header information to git-send-email's
sendemail-validate hook, 2023-04-19), which validates SMTP headers in
the sendemail-validate hook.
Avoid trying to format an undef by storing the given and cleaned address
separately. After applying this fix, the error contains the invalid
email address, and the warning disappears:
$ git.compile send-email --to="pi <pi@pi>" /tmp/x/*.patch --force
error: unable to extract a valid address from: pi <pi@pi>

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).

Back in 280242d1cc (send-email: do not barf when Term::ReadLine does not
like your terminal, 2006-07-02), we added a fallback for when
Term::ReadLine's constructor failed: we'd have a FakeTerm object
instead, which would then die if anybody actually tried to call
readline() on it. Since we instantiated the $term variable at program
startup, we needed this workaround to let the program run in modes when
we did not prompt the user.
But later, in f4dc9432fd (send-email: lazily load modules for a big
speedup, 2021-05-28), we started loading Term::ReadLine lazily only when
ask() is called. So at that point we know we're trying to prompt the
user, and we can just die if ReadLine instantiation fails, rather than
making this fake object to lazily delay showing the error.
This should be OK even if there is no tty (e.g., we're in a cron job),
because Term::ReadLine will return a stub object in that case whose "IN"
and "OUT" functions return undef. And since 5906f54e47 (send-email:
don't attempt to prompt if tty is closed, 2009-03-31), we check for that
case and skip prompting.
And we can be sure that FakeTerm was not kicking in for such a
situation, because it has actually been broken since that commit! It
does not define "IN" or "OUT" methods, so perl would barf with an error.
If FakeTerm was in use, we were neither honoring what 5906f54e47 tried
to do, nor producing the readable message that 280242d1cc intended.
So we're better off just dropping FakeTerm entirely, and letting the
error reported by constructing Term::ReadLine through.

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
latter, which has been corrected. This was a fix for a recent
regression caught before the release, so no need to mention it in
the release notes.
* jc/send-email-pre-process-fix:
t9001: mark the script as no longer leak checker clean
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.

Sometimes, adding a header different than CC or TO is desirable; for
example, when using Debbugs, it is best to use 'X-Debbugs-Cc' headers
to keep people in CC; this is an example use case enabled by the new
'--header-cmd' option.
The header unfolding logic is extracted to a subroutine so that it can
be reused; a test is added for coverage.

hook
To allow further flexibility in the Git hook, the SMTP header
information of the email which git-send-email intends to send, is now
passed as the 2nd argument to the sendemail-validate hook.
As an example, this can be useful for acting upon keywords in the
subject or specific email addresses.

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.

We used to write "Message-Id:" and "Message-ID:" pretty much

used throughout the RFC documents, so let's imitate it ourselves.

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.

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.
