Before submitting patches on the mailing list, it is often a good idea
to check for previous related discussions or if similar work is already
in progress. This enables better coordination amongst contributors and
could avoid duplicating work.
Additionally, it is often recommended to give reviewers some time to
reply to a patch series before sending new versions. This helps collect
broader feedback and reduces unnecessary churn from rapid rerolls.
Document this guidance in "Documentation/SubmittingPatches" accordingly.

The topic so far allows users to tweak the configuration variable
sideband.allowControlCharacters to override the hardcoded default,
but among which there is the value called 'default'. The plan [*]
of the series is to loosen the setting by a later commit in the
series and schedule it to tighten at the Git 3.0 boundary for end
users, at which point, the meaning of this 'default' value will
change.
Which is a dubious design.
A user expresses their preference by setting configuration variable
in order to guard against sudden change brought in by changes to the
hardcoded default behaviour, and letting them set it to 'default'
that will change at the Git 3.0 boundary defeats its purpose. If a
user wants to say "I am easy and can go with whatever hardcoded
default Git implementors choose for me", they simply leave the
configuration variable unspecified.
Let's remove it from the state before Git 3.0 so that those users
who set it to 'default' will not see the behaviour changed under
their feet all of sudden.

The main objection against sanitizing the sideband that was raised
during the review of the sideband sanitizing patches, first on the
git-security mailing list, then on the public mailing list, was that
there are some setups where server-side `pre-receive` hooks want to
error out, giving colorful messages to the users on the client side (if
they are not redirecting the output into a file, that is).
To avoid breaking such setups, the default chosen by the sideband
sanitizing patches is to pass through ANSI color sequences.
Still, there might be some use case out there where that is not enough.
Therefore the `sideband.allowControlCharacters` config setting allows
for configuring levels of sanitizing.
As Junio Hamano pointed out, to keep users safe by default, we need to
be able to scope this to some servers because while a user may trust
their company's Git server, the same might not apply to other Git
servers.
To allow for this, let's imitate the way `http.<url>.*` offers
to scope config settings to certain URLs, by letting users
override the `sideband.allowControlCharacters` setting via
`sideband.<url>.allowControlCharacters`.

Even though control sequences that erase characters are quite juicy for
attack scenarios, where attackers are eager to hide traces of suspicious
activities, during the review of the side band sanitizing patch series
concerns were raised that there might be some legimitate scenarios where
Git server's `pre-receive` hooks use those sequences in a benign way.
Control sequences to move the cursor can likewise be used to hide tracks
by overwriting characters, and have been equally pointed out as having
legitimate users.
Let's add options to let users opt into passing through those ANSI
Escape sequences: `sideband.allowControlCharacters` now supports also
`cursor` and `erase`, and it parses the value as a comma-separated list.

The preceding two commits introduced special handling of the sideband
channel to neutralize ANSI escape sequences before sending the payload
to the terminal, and `sideband.allowControlCharacters` to override that
behavior.
However, as reported by brian m. carlson, some `pre-receive` hooks that
are actively used in practice want to color their messages and therefore
rely on the fact that Git passes them through to the terminal, even
though they have no way to determine whether the receiving side can
actually handle Escape sequences (think e.g. about the practice
recommended by Git that third-party applications wishing to use Git
functionality parse the output of Git commands).
In contrast to other ANSI escape sequences, it is highly unlikely that
coloring sequences can be essential tools in attack vectors that mislead
Git users e.g. by hiding crucial information.
Therefore we can have both: Continue to allow ANSI coloring sequences to
be passed to the terminal by default, and neutralize all other ANSI
Escape sequences.

The preceding commit fixed the vulnerability whereas sideband messages
(that are under the control of the remote server) could contain ANSI
escape sequences that would be sent to the terminal verbatim.
However, this fix may not be desirable under all circumstances, e.g.
when remote servers deliberately add coloring to their messages to
increase their urgency.
To help with those use cases, give users a way to opt-out of the
protections: `sideband.allowControlCharacters`.

The "structure" output for git-repo(1) shows the total inflated and disk
sizes of reachable objects in the repository, but doesn't show the size
of the largest individual objects. Since an individual object may be a
large contributor to the overall repository size, it is useful for users
to know the maximum size of individual objects.
While interating across objects, record the size and OID of the largest
objects encountered for each object type to provide as output. Note that
the default "table" output format only displays size information and not
the corresponding OID. In a subsequent commit, the table format is
updated to add table annotations that mention the OID.

For SMTP servers that do "mutual certificate verification", the mail
client is required to present its own TLS certificate as well. This
patch adds --smtp-ssl-client-cert and --smtp-ssl-client-key for such
servers.
The problem of which private key for the certificate is chosen arises
when there are private keys in both the certificate and private key
file. According to the documentation of IO::Socket::SSL(link supplied),
the behaviour(the private key chosen) depends on the format of the
certificate. In a nutshell,
- PKCS12: the key in the cert always takes the precedence
- PEM: if the key file is not given, it will "try" to read one
from the cert PEM file
Many users may find this discrepancy unintuitive.
In terms of client certificate, git-send-email is implemented in a way
that what's possible with perl's SSL library is exposed to the user as
much as possible. In this instance, the user may choose to use a PEM
file that contains both certificate and private key should be
at their discretion despite the implications.
