Documentation for git-merge incorrectly notes that
tip of the current branch on ascii diagram is C,
while it is actually G (current branch is master,
HEAD on diagram is G).
Additionally diagrams on the page are adjusted
to use spaces instead of tabs, so that they align
regardless of tab size. This is in line with
diagrams on other git documentation pages.

With the preceding commit we have announced the switch to the "reftable"
format in Git 3.0 for newly created repositories. The format is being
battle tested by GitLab and a couple of other developers, and except for
a small handful of issues exposed early after it has been merged it has
been rock solid. Regardless of that though the test user base is still
comparatively small, which increases the risk that we miss critical
bugs.
Address this by enabling the reftable format when experimental features
are enabled. This should increase the test user base by some margin and
thus give us more input before making the format the default.

The "reftable" format has come a long way and has matured nicely since
it has been merged into git via 57db2a094d5 (refs: introduce reftable
backend, 2024-02-07). It fixes longstanding issues that cannot be fixed
with the "files" format in a backwards-compatible way and performs
significantly better in many use cases.
Announce that we will switch to the "reftable" format in Git 3.0 for
newly created repositories and wire up the change, hidden behind the
WITH_BREAKING_CHANGES preprocessor define.
This switch is dependent on support in the larger Git ecosystem. Most
importantly, libraries like JGit, libgit2 and Gitoxide should support
the reftable backend so that we don't break all applications and tools
built on top of those libraries.

Rename `read_object_with_reference()` to `odb_read_object_peeled()` to
match other functions related to the object database and our modern
coding guidelines. Furthermore though, the old name didn't really
describe very well what this function actually does, which is to walk
down any commit and tag objects until an object of the required type has
been found. This is generally referred to as "peeling", so the new name
should be way more descriptive.
No compatibility wrapper is introduced as the function is not used a lot
throughout our codebase.

In ddee3703b3 (builtin/repack.c: add cruft packs to MIDX during
geometric repack, 2022-05-20), repack began adding cruft pack(s) to the
MIDX with '--write-midx' to ensure that the resulting MIDX was always
closed under reachability in order to generate reachability bitmaps.
While the previous patch added the '--stdin-packs=follow' option to
pack-objects, it is not yet on by default. Given that, suppose you have
a once-unreachable object packed in a cruft pack, which later becomes
reachable from one or more objects in a geometrically repacked pack.
That once-unreachable object *won't* appear in the new pack, since the
cruft pack was not specified as included or excluded when the
geometrically repacked pack was created with 'pack-objects
--stdin-packs' (*not* '--stdin-packs=follow', which is not on). If that
new pack is included in a MIDX without the cruft pack, then trying to
generate bitmaps for that MIDX may fail. This happens when the bitmap
selection process picks one or more commits which reach the
once-unreachable objects.
To mitigate this failure mode, commit ddee3703b3 ensures that the MIDX
will be closed under reachability by including cruft pack(s). If cruft
pack(s) were not included, we would fail to generate a MIDX bitmap. But
ddee3703b3 alludes to the fact that this is sub-optimal by saying
[...] it's desirable to avoid including cruft packs in the MIDX
because it causes the MIDX to store a bunch of objects which are
likely to get thrown away.
, which is true, but hides an even larger problem. If repositories
rarely prune their unreachable objects and/or have many of them, the
MIDX must keep track of a large number of objects which bloats the MIDX
and slows down object lookup.
This is doubly unfortunate because the vast majority of objects in cruft
pack(s) are unlikely to be read. But any object lookups that go through
the MIDX must binary search over them anyway, slowing down object
lookups using the MIDX.
This patch causes geometrically-repacked packs to contain a copy of any
once-unreachable object(s) with 'git pack-objects --stdin-packs=follow',
allowing us to avoid including any cruft packs in the MIDX. This is
because a sequence of geometrically-repacked packs that were all
generated with '--stdin-packs=follow' are guaranteed to have their union
be closed under reachability.
Note that you cannot guarantee that a collection of packs is closed
under reachability if not all of them were generated with "following" as
above. One tell-tale sign that not all geometrically-repacked packs in
the MIDX were generated with "following" is to see if there is a pack in
the existing MIDX that is not going to be somehow represented (either
verbatim or as part of a geometric rollup) in the new MIDX.
If there is, then starting to generate packs with "following" during
geometric repacking won't work, since it's open to the same race as
described above.
But if you're starting from scratch (e.g., building the first MIDX after
an all-into-one '--cruft' repack), then you can guarantee that the union
of subsequently generated packs from geometric repacking *is* closed
under reachability.
(One exception here is when "starting from scratch" results in a noop
repack, e.g., because the non-cruft pack(s) in a repository already form
a geometric progression. Since we can't tell whether or not those were
generated with '--stdin-packs=follow', they may depend on
once-unreachable objects, so we have to include the cruft pack in the
MIDX in this case.)
Detect when this is the case and avoid including cruft packs in the MIDX
where possible. The existing behavior remains the default, and the new
behavior is available with the config 'repack.midxMustIncludeCruft' set
to 'false'.

When invoked with '--stdin-packs', pack-objects will generate a pack
which contains the objects found in the "included" packs, less any
objects from "excluded" packs.
Packs that exist in the repository but weren't specified as either
included or excluded are in practice treated like the latter, at least
in the sense that pack-objects won't include objects from those packs.
This behavior forces us to include any cruft pack(s) in a repository's
multi-pack index for the reasons described in ddee3703b3
(builtin/repack.c: add cruft packs to MIDX during geometric repack,
2022-05-20).
The full details are in ddee3703b3, but the gist is if you
have a once-unreachable object in a cruft pack which later becomes
reachable via one or more commits in a pack generated with
'--stdin-packs', you *have* to include that object in the MIDX via the
copy in the cruft pack, otherwise we cannot generate reachability
bitmaps for any commits which reach that object.
Note that the traversal here is best-effort, similar to the existing
traversal which provides name-hash hints. This means that the object
traversal may hand us back a blob that does not actually exist. We
*won't* see missing trees/commits with 'ignore_missing_links' because:
- missing commit parents are discarded at the commit traversal stage by
revision.c::process_parents()
- missing tag objects are discarded by revision.c::handle_commit()
- missing tree objects are discarded by the list-objects code in
list-objects.c::process_tree()
But we have to handle potentially-missing blobs specially by making a
separate check to ensure they exist in the repository. Failing to do so
would mean that we'd add an object to the packing list which doesn't
actually exist, rendering us unable to write out the pack.
This prepares us for new repacking behavior which will "resurrect"
objects found in cruft or otherwise unspecified packs when generating
new packs. In the context of geometric repacking, this may be used to
maintain a sequence of geometrically-repacked packs, the union of which
is closed under reachability, even in the case described earlier.

Various IMAP servers have different ways to name common folders.
For example, the folder where all deleted messages are stored is often
named "[Gmail]/Trash" on Gmail servers, and "Deleted" on Outlook.
Similarly, the Drafts folder is simply named "Drafts" on Outlook, but
on Gmail it is named "[Gmail]/Drafts".
This commit adds a `--list` command to the `imap-send` tool that lists
the available folders on the IMAP server, allowing users to see
which folders are available and how they are named. A sample output
looks like this when run against a Gmail server:
Fetching the list of available folders...
* LIST (\HasNoChildren) "/" "INBOX"
* LIST (\HasChildren \Noselect) "/" "[Gmail]"
* LIST (\All \HasNoChildren) "/" "[Gmail]/All Mail"
* LIST (\Drafts \HasNoChildren) "/" "[Gmail]/Drafts"
* LIST (\HasNoChildren \Important) "/" "[Gmail]/Important"
* LIST (\HasNoChildren \Sent) "/" "[Gmail]/Sent Mail"
* LIST (\HasNoChildren \Junk) "/" "[Gmail]/Spam"
* LIST (\Flagged \HasNoChildren) "/" "[Gmail]/Starred"
* LIST (\HasNoChildren \Trash) "/" "[Gmail]/Trash"
For OpenSSL, this is achived by running the 'IMAP LIST' command and
parsing the response. This command is specified in RFC6154:
https://datatracker.ietf.org/doc/html/rfc6154#section-5.1
For libcurl, the example code published in the libcurl documentation
is used to implement this functionality:
