Introduce and use the new "best effort" strategy for Secure Channel revoke checking

081e084eaa http: use new "best effort" strategy for Secure Channel revoke checking
The native Windows HTTPS backend is based on Secure Channel which lets
the caller decide how to handle revocation checking problems caused by
missing information in the certificate or offline CRL distribution
points.

Unfortunately, cURL chose to handle these problems differently than
OpenSSL by default: while OpenSSL happily ignores those problems
(essentially saying "¯\_(ツ)_/¯"), the Secure Channel backend will error
out instead.

As a remedy, the "no revoke" mode was introduced, which turns off
revocation checking altogether. This is a bit heavy-handed. We support
this via the `http.schannelCheckRevoke` setting.

In https://github.com/curl/curl/pull/4981, we contributed an opt-in
"best effort" strategy that emulates what OpenSSL seems to do.

In Git for Windows, we actually want this to be the default. This patch
makes it so, introducing it as a new value for the
`http.schannelCheckRevoke" setting, which now becmes a tristate: it
accepts the values "false", "true" or "best-effort" (defaulting to the
last one).

4689c6f3e0 transport: optionally disable side-band-64k
Since commit 0c499ea60f (send-pack: demultiplex a sideband stream with
status data, 2010-02-05) the send-pack builtin uses the side-band-64k
capability if advertised by the server.

Unfortunately this breaks pushing over the dump git protocol if used
over a network connection.

The detailed reasons for this breakage are (by courtesy of Jeff Preshing,
quoted from https://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ):

	MinGW wraps Windows sockets in CRT file descriptors in order to
	mimic the functionality of POSIX sockets. This causes msvcrt.dll
	to treat sockets as Installable File System (IFS) handles,
	calling ReadFile, WriteFile, DuplicateHandle and CloseHandle on
	them. This approach works well in simple cases on recent
	versions of Windows, but does not support all usage patterns. In
	particular, using this approach, any attempt to read & write
	concurrently on the same socket (from one or more processes)
	will deadlock in a scenario where the read waits for a response
	from the server which is only invoked after the write. This is
	what send_pack currently attempts to do in the use_sideband
	codepath.

The new config option `sendpack.sideband` allows to override the
side-band-64k capability of the server, and thus makes the dumb git
protocol work.

Other transportation methods like ssh and http/https still benefit from
the sideband channel, therefore the default value of `sendpack.sideband`
is still true.

eb92506c18 sideband: do allow ANSI color sequences by default
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, 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.

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, and neutralize all other ANSI escape
sequences.

7227785b34 sideband: introduce an "escape hatch" to allow control characters
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`.

a65cbd87ea gitglossary: fix indentation of sub-lists
The glossary entry is a list of terms and their definitions, so
multi-paragraph definitions need "+" continuation lines to indicate
that they are part of a single entry.

When an entry contains a sub-list (say, a bulleted list), the final "+"
may become ambiguous: is it connecting the next paragraph to the final
entry of the sub-list, or to the original list of definition paragraphs?

Asciidoc generally connects it to the former, even when we mean the
latter, and you end up with the next paragraph indented incorrectly,
like this:

  glob
    ...defines glob...

    Two consecutive asterisks ("**") in patterns matched
    against full pathname may have special meaning:

    - ...some special meaning of **...

    - ...another special meaning of **...

    - Other consecutive asterisks are considered invalid.

      Glob magic is incompatible with literal magic.

That final "Glob magic is incompatible" paragraph is in the wrong spot.
It should be at the same level as "Two consecutive asterisks", as it is
not part of the final "Other consecutive asterisks" bullet point.

The same problem appears in several other spots in the glossary.

Usually we'd fix this by using "--" markers, which put the sub-list into
its own block. But there's a catch: in some of these spots we are
already in an open block, and nesting open blocks is a problem. It seems
to work for me using Asciidoc 10.2.1, but Asciidoctor 2.0.26 makes a
mess of it (our intent to open a new block seems to close the old one).

Fortunately there's a work-around: when using a "+" list-continuation,
the number of empty lines above the continuation indicates which level
of parent list to continue. So by adding an empty line after our
unordered list (before the "+"), we should be able to continue the
definition list item.

But asciidoc being asciidoc, of course that is not the end of the story.
That technique works fine for the "glob" and "attr" lists in this patch,
but under the "refs" item it works for only 1 of the 2 lists! I can't
figure out why, and this may be an asciidoctor bug. But we can work
around it by using "--" open-block markers here, since we're not
already in an open block.

So using the extra blank line for the first two instances, and "--"
markers for the second two, this patch produces identical output from
"doc-diff HEAD^ HEAD" for both --asciidoctor and --asciidoc modes.

444e423f81 doc: am: revert Message-ID trailer claim
I claimed in 3c18135b (doc: am: say that --message-id adds a trailer,
2026-02-09) that `git am --message-id` adds a Git trailer. But that
isn’t the case; for the case of a commit message with a subject, body,
and no trailer block:

    <subject>

    <paragrah>

It just appends the line right after `paragraph`:

    <subject>

    <paragraph>
    Message-ID: <message-id_trailer.323@msgid.xyz>

It does work for two other cases though, namely subject-only and with an
existing trailer block.

This is at best an inconsistency and arguably a bug, but we’re at the
trailing end of the release cycle now. So reverting the doc is safer
than making msg-id act as a trailer, for now.

Revert this hunk from commit 3c18135b except the only useful
change (“Also use inline-verbatim for `Message-ID`”).

57177ad139 doc: gitcvs-migration: rephrase “man page”
Let’s change the phrasing around the `linkgit` while we’re visiting this
file (see previous commit[1]).

We use the section syntax to refer to man pages, so writing “man page”
next to it is a bit redundant. We can be more concise and just lean on
the preposition “in”.

And in order to avoid this double “git”:

    see `git config list` in git-config(1) ...

We can rephrase to the subcommand, which is a typical pattern (config or
option followed by “in git-command(1)”).

† 1: Which also discusses why we do not change a similar phrasing
     in gittutorial(7)

To enable users to specify which ref to update, add option '--ref'. When
using option '--ref', the refs described above are left untouched and
instead the argument of this option is updated instead.

Because this introduces code paths in replay.c that jump to `out` before

3f7c0e722e pack-objects: support excluded-open packs with --stdin-packs
In cd846bacc7 (pack-objects: introduce '--stdin-packs=follow',
2025-06-23), pack-objects learned to traverse through commits in
included packs when using '--stdin-packs=follow', rescuing reachable
objects from unlisted packs into the output.

When we encounter a commit in an excluded pack during this rescuing
phase we will traverse through its parents. But because we set
`revs.no_kept_objects = 1`, commit simplification will prevent us from
showing it via `get_revision()`. (In practice, `--stdin-packs=follow`
walks commits down to the roots, but only opens up trees for ones that
do not appear in an excluded pack.)

But there are certain cases where we *do* need to see the parents of an
object in an excluded pack. Namely, if an object is rescue-able, but
only reachable from object(s) which appear in excluded packs, then
commit simplification will exclude those commits from the object
traversal, and we will never see a copy of that object, and thus not
rescue it.

This is what causes the failure in the previous commit during repacking.
When performing a geometric repack, packs above the geometric split that
weren't part of the previous MIDX (e.g., packs pushed directly into
`$GIT_DIR/objects/pack`) may not have full object closure.  When those
packs are listed as excluded via the '^' marker, the reachability
traversal encounters the sequence described above, and may miss objects
which we expect to rescue with `--stdin-packs=follow`.

Introduce a new "excluded-open" pack prefix, '!'. Like '^'-prefixed
packs, objects from '!'-prefixed packs are excluded from the resulting
pack. But unlike '^', commits in '!'-prefixed packs *are* used as
starting points for the follow traversal, and the traversal does not
treat them as a closure boundary.

In order to distinguish excluded-closed from excluded-open packs during
the traversal, introduce a new `pack_keep_in_core_open` bit on
`struct packed_git`, along with a corresponding `KEPT_PACK_IN_CORE_OPEN`
flag for the kept-pack cache.

In `add_object_entry_from_pack()`, move the `want_object_in_pack()`
check to *after* `add_pending_oid()`. This is necessary so that commits
from excluded-open packs are added as traversal tips even though their
objects won't appear in the output. As a consequence, the caller
`for_each_object_in_pack()` will always provide a non-NULL 'p', hence we
are able to drop the "if (p)" conditional.

The `include_check` and `include_check_obj` callbacks on `rev_info` are
used to halt the walk at closed-excluded packs, since objects behind a
'^' boundary are guaranteed to have closure and need not be rescued.

The following commit will make use of this new functionality within the
repack layer to resolve the test failure demonstrated in the previous
commit.

0284046ad0 format-patch: removing unconditional wrapping
Using format-patch with --commit-list-format different than shortlog,
causes the commit entry lines to wrap if they get longer than
MAIL_DEFAULT_WRAP (72 characters).

While this might be sensible for many when sending changes through
email, it forces this decision of wrapping on the user, reducing the
control granularity of --commit-list-format.

Teach generate_commit_list_cover() to respect commit entry line lengths
and place this wrapping rule on the "modern" preset format instead.

acee42d3e5 docs: fix --commit-list-format related entries
Documentation specifies that "git format-patch" would default to
format.commitListFormat if --commit-list-format is not given, but
doesn't specify the default if the format.commitListFormat is not set.
The text for --cover-letter is also obsolete as the commit list can now
be something other than a shortlog.

Document to reflect changes.
