- from objects in a pack that came from a promissor remote is OK.

+Git 2.18 Release Notes
+======================
+
+Updates since v2.17
+-------------------
+
+UI, Workflows & Features
+
+ * Rename detection logic that is used in "merge" and "cherry-pick" has
+ learned to guess when all of x/a, x/b and x/c have moved to z/a,
+ z/b and z/c, it is likely that x/d added in the meantime would also
+ want to move to z/d by taking the hint that the entire directory
+ 'x' moved to 'z'. A bug causing dirty files involved in a rename
+ to be overwritten during merge has also been fixed as part of this
+ work. Incidentally, this also avoids updating a file in the
+ working tree after a (non-trivial) merge whose result matches what
+ our side originally had.
+
+ * "git filter-branch" learned to use a different exit code to allow
+ the callers to tell the case where there was no new commits to
+ rewrite from other error cases.
+
+ * When built with more recent cURL, GIT_SSL_VERSION can now specify
+ "tlsv1.3" as its value.
+
+ * "git gui" learned that "~/.ssh/id_ecdsa.pub" and
+ "~/.ssh/id_ed25519.pub" are also possible SSH key files.
+ (merge 2e2f0288ef bb/git-gui-ssh-key-files later to maint).
+
+ * "git gui" performs commit upon CTRL/CMD+ENTER but the
+ CTRL/CMD+KP_ENTER (i.e. enter key on the numpad) did not have the
+ same key binding. It now does.
+ (merge 28a1d94a06 bp/git-gui-bind-kp-enter later to maint).
+
+ * "git gui" has been taught to work with old versions of tk (like
+ 8.5.7) that do not support "ttk::style theme use" as a way to query
+ the current theme.
+ (merge 4891961105 cb/git-gui-ttk-style later to maint).
+
+ * "git rebase" has learned to honor "--signoff" option when using
+ backends other than "am" (but not "--preserve-merges").
+
+ * "git branch --list" during an interrupted "rebase -i" now lets
+ users distinguish the case where a detached HEAD is being rebased
+ and a normal branch is being rebased.
+
+ * "git mergetools" learned talking to guiffy.
+
+ * The scripts in contrib/emacs/ have outlived their usefulness and
+ have been replaced with a stub that errors out and tells the user
+ there are replacements.
+
+ * The new "working-tree-encoding" attribute can ask Git to convert the
+ contents to the specified encoding when checking out to the working
+ tree (and the other way around when checking in).
+
+ * The "git config" command uses separate options e.g. "--int",
+ "--bool", etc. to specify what type the caller wants the value to
+ be interpreted as. A new "--type=<typename>" option has been
+ introduced, which would make it cleaner to define new types.
+
+ * "git config --get" learned the "--default" option, to help the
+ calling script. Building on top of the above changes, the
+ "git config" learns "--type=color" type. Taken together, you can
+ do things like "git config --get foo.color --default blue" and get
+ the ANSI color sequence for the color given to foo.color variable,
+ or "blue" if the variable does not exist.
+
+ * "git ls-remote" learned an option to allow sorting its output based
+ on the refnames being shown.
+
+ * The command line completion (in contrib/) has been taught that "git
+ stash save" has been deprecated ("git stash push" is the preferred
+ spelling in the new world) and does not offer it as a possible
+ completion candidate when "git stash push" can be.
+
+ * "git gc --prune=nonsense" spent long time repacking and then
+ silently failed when underlying "git prune --expire=nonsense"
+ failed to parse its command line. This has been corrected.
+
+ * Error messages from "git push" can be painted for more visibility.
+
+ * "git http-fetch" (deprecated) had an optional and experimental
+ "feature" to fetch only commits and/or trees, which nobody used.
+ This has been removed.
+
+ * The functionality of "$GIT_DIR/info/grafts" has been superseded by
+ the "refs/replace/" mechanism for some time now, but the internal
+ code had support for it in many places, which has been cleaned up
+ in order to drop support of the "grafts" mechanism.
+
+ * "git worktree add" learned to check out an existing branch.
+
+ * "git --no-pager cmd" did not have short-and-sweet single letter
+ option. Now it does as "-P".
+ (merge 7213c28818 js/no-pager-shorthand later to maint).
+
+ * "git rebase" learned "--rebase-merges" to transplant the whole
+ topology of commit graph elsewhere.
+
+ * "git status" learned to pay attention to UI related diff
+ configuration variables such as diff.renames.
+
+ * The command line completion mechanism (in contrib/) learned to load
+ custom completion file for "git $command" where $command is a
+ custom "git-$command" that the end user has on the $PATH when using
+ newer version of bash-completion.
+
+ * "git send-email" can sometimes offer confirmation dialog "Send this
+ email?" with choices 'Yes', 'No', 'Quit', and 'All'. A new action
+ 'Edit' has been added to this dialog's choice.
+
+ * With merge.renames configuration set to false, the recursive merge
+ strategy can be told not to spend cycles trying to find renamed
+ paths and merge them accordingly.
+
+ * "git status" learned to honor a new status.renames configuration to
+ skip rename detection, which could be useful for those who want to
+ do so without disabling the default rename detection done by the
+ "git diff" command.
+
+ * Command line completion (in contrib/) learned to complete pathnames
+ for various commands better.
+
+ * "git blame" learns to unhighlight uninteresting metadata from the
+ originating commit on lines that are the same as the previous one,
+ and also paint lines in different colors depending on the age of
+ the commit.
+
+ * Transfer protocol v2 learned to support the partial clone.
+
+ * When a short hexadecimal string is used to name an object but there
+ are multiple objects that share the string as the prefix of their
+ names, the code lists these ambiguous candidates in a help message.
+ These object names are now sorted according to their types for
+ easier eyeballing.
+
+ * "git fetch $there $refspec" that talks over protocol v2 can take
+ advantage of server-side ref filtering; the code has been extended
+ so that this mechanism triggers also when fetching with configured
+ refspec.
+
+ * Our HTTP client code used to advertise that we accept gzip encoding
+ from the other side; instead, just let cURL library to advertise
+ and negotiate the best one.
+
+ * "git p4" learned to "unshelve" shelved commit from P4.
+ (merge 123f631761 ld/p4-unshelve later to maint).
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * A "git fetch" from a repository with insane number of refs into a
+ repository that is already up-to-date still wasted too many cycles
+ making many lstat(2) calls to see if these objects at the tips
+ exist as loose objects locally. These lstat(2) calls are optimized
+ away by enumerating all loose objects beforehand.
+ It is unknown if the new strategy negatively affects existing use
+ cases, fetching into a repository with many loose objects from a
+ repository with small number of refs.
+
+ * Git can be built to use either v1 or v2 of the PCRE library, and so
+ far, the build-time configuration USE_LIBPCRE=YesPlease instructed
+ the build procedure to use v1, but now it means v2. USE_LIBPCRE1
+ and USE_LIBPCRE2 can be used to explicitly choose which version to
+ use, as before.
+
+ * The build procedure learned to optionally use symbolic links
+ (instead of hardlinks and copies) to install "git-foo" for built-in
+ commands, whose binaries are all identical.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * The way "git worktree prune" worked internally has been simplified,
+ by assuming how "git worktree move" moves an existing worktree to a
+ different place.
+
+ * Code clean-up for the "repository" abstraction.
+ (merge 00a3da2a13 nd/remove-ignore-env-field later to maint).
+
+ * Code to find the length to uniquely abbreviate object names based
+ on packfile content, which is a relatively recent addtion, has been
+ optimized to use the same fan-out table.
+
+ * The mechanism to use parse-options API to automate the command line
+ completion continues to get extended and polished.
+
+ * Copies of old scripted Porcelain commands in contrib/examples/ have
+ been removed.
+
+ * Some tests that rely on the exact hardcoded values of object names
+ have been updated in preparation for hash function migration.
+
+ * Perf-test update.
+
+ * Test helper update.
+
+ * The effort continues to refactor the internal global data structure
+ to make it possible to open multiple repositories, work with and
+ then close them,
+
+ * Small test-helper programs have been consolidated into a single
+ binary.
+
+ * API clean-up around ref-filter code.
+
+ * Shell completion (in contrib) that gives list of paths have been
+ optimized somewhat.
+
+ * The index file is updated to record the fsmonitor section after a
+ full scan was made, to avoid wasting the effort that has already
+ spent.
+
+ * Performance measuring framework in t/perf learned to help bisecting
+ performance regressions.
+
+ * Some multi-word source filenames are being renamed to separate
+ words with dashes instead of underscores.
+
+ * An reusable "memory pool" implementation has been extracted from
+ fast-import.c, which in turn has become the first user of the
+ mem-pool API.
+
+ * A build-time option has been added to allow Git to be told to refer
+ to its associated files relative to the main binary, in the same
+ way that has been possible on Windows for quite some time, for
+ Linux, BSDs and Darwin.
+
+ * Precompute and store information necessary for ancestry traversal
+ in a separate file to optimize graph walking.
+
+ * The effort to pass the repository in-core structure throughout the
+ API continues. This round deals with the code that implements the
+ refs/replace/ mechanism.
+
+ * The build procedure "make DEVELOPER=YesPlease" learned to enable a
+ bit more warning options depending on the compiler used to help
+ developers more. There also is "make DEVOPTS=tokens" knob
+ available now, for those who want to help fixing warnings we
+ usually ignore, for example.
+
+ * A new version of the transport protocol is being worked on.
+
+ * The code to interface to GPG has been restructured somewhat to make
+ it cleaner to integrate with other types of signature systems later.
+
+ * The code has been taught to use the duplicated information stored
+ in the commit-graph file to learn the tree object name for a commit
+ to avoid opening and parsing the commit object when it makes sense
+ to do so.
+
+ * "git gc" in a large repository takes a lot of time as it considers
+ to repack all objects into one pack by default. The command has
+ been taught to pretend as if the largest existing packfile is
+ marked with ".keep" so that it is left untouched while objects in
+ other packs and loose ones are repacked.
+
+ * The transport protocol v2 is getting updated further.
+
+ * The codepath around object-info API has been taught to take the
+ repository object (which in turn tells the API which object store
+ the objects are to be located).
+
+ * "git pack-objects" needs to allocate tons of "struct object_entry"
+ while doing its work, and shrinking its size helps the performance
+ quite a bit.
+
+ * The implementation of "git rebase -i --root" has been updated to use
+ the sequencer machinery more.
+
+ * Developer support update, by using BUG() macro instead of die() to
+ mark codepaths that should not happen more clearly.
+
+ * Developer support. Use newer GCC on one of the builds done at
+ TravisCI.org to get more warnings and errors diagnosed.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * By code restructuring of submodule merge in merge-recursive,
+ informational messages from the codepath are now given using the
+ same mechanism as other output, and honor the merge.verbosity
+ configuration. The code also learned to give a few new messages
+ when a submodule three-way merge resolves cleanly when one side
+ records a descendant of the commit chosen by the other side.
+
+ * Avoid unchecked snprintf() to make future code auditing easier.
+ (merge ac4896f007 jk/snprintf-truncation later to maint).
+
+ * Many tests hardcode the raw object names, which would change once
+ we migrate away from SHA-1. While some of them must test against
+ exact object names, most of them do not have to use hardcoded
+ constants in the test. The latter kind of tests have been updated
+ to test the moral equivalent of the original without hardcoding the
+ actual object names.
+
+ * The list of commands with their various attributes were spread
+ across a few places in the build procedure, but it now is getting a
+ bit more consolidated to allow more automation.
+
+ * Quite a many tests assumed that newly created refs are made as
+ loose refs using the files backend, which have been updated to use
+ proper plumbing like rev-parse and update-ref, to avoid breakage
+ once we start using different ref backends.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.17
+-----------------
+
+ * "git shortlog cruft" aborted with a BUG message when run outside a
+ Git repository. The command has been taught to complain about
+ extra and unwanted arguments on its command line instead in such a
+ case.
+ (merge 4aa0161e83 ma/shortlog-revparse later to maint).
+
+ * "git stash push -u -- <pathspec>" gave an unnecessary and confusing
+ error message when there was no tracked files that match the
+ <pathspec>, which has been fixed.
+ (merge 353278687e tg/stash-untracked-with-pathspec-fix later to maint).
+
+ * "git tag --contains no-such-commit" gave a full list of options
+ after giving an error message.
+ (merge 3bb0923f06 ps/contains-id-error-message later to maint).
+
+ * "diff-highlight" filter (in contrib/) learned to understand "git log
+ --graph" output better.
+ (merge 4551fbba14 jk/diff-highlight-graph-fix later to maint).
+
+ * when refs that do not point at committish are given, "git
+ filter-branch" gave a misleading error messages. This has been
+ corrected.
+ (merge f78ab355e7 yk/filter-branch-non-committish-refs later to maint).
+
+ * "git submodule status" misbehaved on a submodule that has been
+ removed from the working tree.
+ (merge 74b6bda32f rs/status-with-removed-submodule later to maint).
+
+ * When credential helper exits very quickly without reading its
+ input, it used to cause Git to die with SIGPIPE, which has been
+ fixed.
+ (merge a0d51e8d0e eb/cred-helper-ignore-sigpipe later to maint).
+
+ * "git rebase --keep-empty" still removed an empty commit if the
+ other side contained an empty commit (due to the "does an
+ equivalent patch exist already?" check), which has been corrected.
+ (merge 3d946165e1 pw/rebase-keep-empty-fixes later to maint).
+
+ * Some codepaths, including the refs API, get and keep relative
+ paths, that go out of sync when the process does chdir(2). The
+ chdir-notify API is introduced to let these codepaths adjust these
+ cached paths to the new current directory.
+ (merge fb9c2d2703 jk/relative-directory-fix later to maint).
+
+ * "cd sub/dir && git commit ../path" ought to record the changes to
+ the file "sub/path", but this regressed long time ago.
+ (merge 86238e07ef bw/commit-partial-from-subdirectory-fix later to maint).
+
+ * Recent introduction of "--log-destination" option to "git daemon"
+ did not work well when the daemon was run under "--inetd" mode.
+ (merge e67d906d73 lw/daemon-log-destination later to maint).
+
+ * Small fix to the autoconf build procedure.
+ (merge 249482daf0 es/fread-reads-dir-autoconf-fix later to maint).
+
+ * Fix an unexploitable (because the oversized contents are not under
+ attacker's control) buffer overflow.
+ (merge d8579accfa bp/fsmonitor-bufsize-fix later to maint).
+
+ * Recent simplification of build procedure forgot a bit of tweak to
+ the build procedure of contrib/mw-to-git/
+ (merge d8698987f3 ab/simplify-perl-makefile later to maint).
+
+ * Moving a submodule that itself has submodule in it with "git mv"
+ forgot to make necessary adjustment to the nested sub-submodules;
+ now the codepath learned to recurse into the submodules.
+
+ * "git config --unset a.b", when "a.b" is the last variable in an
+ otherwise empty section "a", left an empty section "a" behind, and
+ worse yet, a subsequent "git config a.c value" did not reuse that
+ empty shell and instead created a new one. These have been
+ (partially) corrected.
+ (merge c71d8bb38a js/empty-config-section-fix later to maint).
+
+ * "git worktree remove" learned that "-f" is a shorthand for
+ "--force" option, just like for "git worktree add".
+ (merge d228eea514 sb/worktree-remove-opt-force later to maint).
+
+ * The completion script (in contrib/) learned to clear cached list of
+ command line options upon dot-sourcing it again in a more efficient
+ way.
+ (merge 94408dc71c sg/completion-clear-cached later to maint).
+
+ * "git svn" had a minor thinko/typo which has been fixed.
+ (merge 51db271587 ab/git-svn-get-record-typofix later to maint).
+
+ * During a "rebase -i" session, the code could give older timestamp
+ to commits created by later "pick" than an earlier "reword", which
+ has been corrected.
+ (merge 12f7babd6b js/ident-date-fix later to maint).
+
+ * "git submodule status" did not check the symbolic revision name it
+ computed for the submodule HEAD is not the NULL, and threw it at
+ printf routines, which has been corrected.
+ (merge 0b5e2ea7cf nd/submodule-status-fix later to maint).
+
+ * When fed input that already has In-Reply-To: and/or References:
+ headers and told to add the same information, "git send-email"
+ added these headers separately, instead of appending to an existing
+ one, which is a violation of the RFC. This has been corrected.
+ (merge 256be1d3f0 sa/send-email-dedup-some-headers later to maint).
+
+ * "git fast-export" had a regression in v2.15.0 era where it skipped
+ some merge commits in certain cases, which has been corrected.
+ (merge be011bbe00 ma/fast-export-skip-merge-fix later to maint).
+
+ * The code did not propagate the terminal width to subprocesses via
+ COLUMNS environment variable, which it now does. This caused
+ trouble to "git column" helper subprocess when "git tag --column=row"
+ tried to list the existing tags on a display with non-default width.
+ (merge b5d5a567fb nd/term-columns later to maint).
+
+ * We learned that our source files with ".pl" and ".py" extensions
+ are Perl and Python files respectively and changes to them are
+ better viewed as such with appropriate diff drivers.
+ (merge 7818b619e2 ab/perl-python-attrs later to maint).
+
+ * "git rebase -i" sometimes left intermediate "# This is a
+ combination of N commits" message meant for the human consumption
+ inside an editor in the final result in certain corner cases, which
+ has been fixed.
+ (merge 15ef69314d js/rebase-i-clean-msg-after-fixup-continue later to maint).
+
+ * A test to see if the filesystem normalizes UTF-8 filename has been
+ updated to check what we need to know in a more direct way, i.e. a
+ path created in NFC form can be accessed with NFD form (or vice
+ versa) to cope with APFS as well as HFS.
+ (merge 742ae10e35 tb/test-apfs-utf8-normalization later to maint).
+
+ * "git format-patch --cover --attach" created a broken MIME multipart
+ message for the cover letter, which has been fixed by keeping the
+ cover letter as plain text file.
+ (merge 50cd54ef4e bc/format-patch-cover-no-attach later to maint).
+
+ * The split-index feature had a long-standing and dormant bug in
+ certain use of the in-core merge machinery, which has been fixed.
+ (merge 7db118303a en/unpack-trees-split-index-fix later to maint).
+
+ * Asciidoctor gives a reasonable imitation for AsciiDoc, but does not
+ render illustration in a literal block correctly when indented with
+ HT by default. The problem is fixed by forcing 8-space tabs.
+ (merge 379805051d bc/asciidoctor-tab-width later to maint).
+
+ * Code clean-up to adjust to a more recent lockfile API convention that
+ allows lockfile instances kept on the stack.
+ (merge 0fa5a2ed8d ma/lockfile-cleanup later to maint).
+
+ * the_repository->index is not a allocated piece of memory but
+ repo_clear() indiscriminately attempted to free(3) it, which has
+ been corrected.
+ (merge 74373b5f10 nd/repo-clear-keep-the-index later to maint).
+
+ * Code clean-up to avoid non-standard-conformant pointer arithmetic.
+ (merge c112084af9 rs/no-null-ptr-arith-in-fast-export later to maint).
+
+ * Code clean-up to turn history traversal more robust in a
+ semi-corrupt repository.
+ (merge 8702b30fd7 jk/unavailable-can-be-missing later to maint).
+
+ * "git update-ref A B" is supposed to ensure that ref A does not yet
+ exist when B is a NULL OID, but this check was not done correctly
+ for pseudo-refs outside refs/ hierarchy, e.g. MERGE_HEAD.
+
+ * "git submodule update" and "git submodule add" supported the
+ "--reference" option to borrow objects from a neighbouring local
+ repository like "git clone" does, but lacked the more recent
+ invention "--dissociate". Also "git submodule add" has been taught
+ to take the "--progress" option.
+ (merge a0ef29341a cf/submodule-progress-dissociate later to maint).
+
+ * Update credential-netrc helper (in contrib/) to allow customizing
+ the GPG used to decrypt the encrypted .netrc file.
+ (merge 786ef50a23 lm/credential-netrc later to maint).
+
+ * "git submodule update" attempts two different kinds of "git fetch"
+ against the upstream repository to grab a commit bound at the
+ submodule's path, but it incorrectly gave up if the first kind
+ (i.e. a normal fetch) failed, making the second "last resort" one
+ (i.e. fetching an exact commit object by object name) ineffective.
+ This has been corrected.
+ (merge e30d833671 sb/submodule-update-try-harder later to maint).
+
+ * Error behaviour of "git grep" when it cannot read the index was
+ inconsistent with other commands that uses the index, which has
+ been corrected to error out early.
+ (merge b2aa84c789 sb/grep-die-on-unreadable-index later to maint).
+
+ * We used to call regfree() after regcomp() failed in some codepaths,
+ which have been corrected.
+ (merge 17154b1576 ma/regex-no-regfree-after-comp-fail later to maint).
+
+ * The import-tars script (in contrib/) has been taught to handle
+ tarballs with overly long paths that use PAX extended headers.
+ (merge 12ecea46e3 pa/import-tars-long-names later to maint).
+
+ * "git rev-parse Y..." etc. misbehaved when given endpoints were
+ not committishes.
+ (merge 0ed556d38f en/rev-parse-invalid-range later to maint).
+
+ * "git pull --recurse-submodules --rebase", when the submodule
+ repository's history did not have anything common between ours and
+ the upstream's, failed to execute. We need to fetch from them to
+ continue even in such a case.
+ (merge 4d36f88be7 jt/submodule-pull-recurse-rebase later to maint).
+
+ * "git remote update" can take both a single remote nickname and a
+ nickname for remote groups, but only one of them was documented.
+ (merge a97447a42a nd/remote-update-doc later to maint).
+
+ * "index-pack --strict" has been taught to make sure that it runs the
+ final object integrity checks after making the freshly indexed
+ packfile available to itself.
+ (merge 3737746120 jk/index-pack-maint later to maint).
+
+ * Make zlib inflate codepath more robust against versions of zlib
+ that clobber unused portion of outbuf.
+ (merge b611396e97 jl/zlib-restore-nul-termination later to maint).
+
+ * Fix old merge glitch in Documentation during v2.13-rc0 era.
+ (merge 28cb06020b mw/doc-merge-enumfix later to maint).
+
+ * The code to read compressed bitmap was not careful to avoid reading
+ past the end of the file, which has been corrected.
+ (merge 1140bf01ec jk/ewah-bounds-check later to maint).
+
+ * "make NO_ICONV=NoThanks" did not override NEEDS_LIBICONV
+ (i.e. linkage of -lintl, -liconv, etc. that are platform-specific
+ tweaks), which has been corrected.
+ (merge fdb1fbbc7d es/make-no-iconv later to maint).
+
+ * Other minor doc, test and build updates and code cleanups.

+'git commit-graph read' [--object-dir <dir>]
+'git commit-graph write' <options> [--object-dir <dir>]
+
+
+DESCRIPTION
+-----------
+
+Manage the serialized commit graph file.
+
+
+OPTIONS
+-------
+--object-dir::
+ Use given directory for the location of packfiles and commit graph
+ file. This parameter exists to specify the location of an alternate
+ that only has the objects directory, not a full .git directory. The
+ commit graph file is expected to be at <dir>/info/commit-graph and
+ the packfiles are expected to be in <dir>/pack.
+
+
+COMMANDS
+--------
+'write'::
+
+Write a commit graph file based on the commits found in packfiles.
++
+With the `--stdin-packs` option, generate the new commit graph by
+walking objects only in the specified pack-indexes. (Cannot be combined
+with --stdin-commits.)
++
+With the `--stdin-commits` option, generate the new commit graph by
+walking commits starting at the commits specified in stdin as a list
+of OIDs in hex, one OID per line. (Cannot be combined with
+--stdin-packs.)
++
+With the `--append` option, include all commits that are present in the
+existing commit-graph file.
+
+'read'::
+
+Read a graph file given by the commit-graph file and output basic
+details about the graph file. Used for debugging purposes.

+REBASING MERGES
+-----------------
+
+The interactive rebase command was originally designed to handle
+individual patch series. As such, it makes sense to exclude merge
+commits from the todo list, as the developer may have merged the
+then-current `master` while working on the branch, only to rebase
+all the commits onto `master` eventually (skipping the merge
+commits).
+
+However, there are legitimate reasons why a developer may want to
+recreate merge commits: to keep the branch structure (or "commit
+topology") when working on multiple, inter-related branches.
+
+In the following example, the developer works on a topic branch that
+refactors the way buttons are defined, and on another topic branch
+that uses that refactoring to implement a "Report a bug" button. The
+output of `git log --graph --format=%s -5` may look like this:
+
+------------
+* Merge branch 'report-a-bug'
+|\
+| * Add the feedback button
+* | Merge branch 'refactor-button'
+|\ \
+| |/
+| * Use the Button class for all buttons
+| * Extract a generic Button class from the DownloadButton one
+------------
+
+The developer might want to rebase those commits to a newer `master`
+while keeping the branch topology, for example when the first topic
+branch is expected to be integrated into `master` much earlier than the
+second one, say, to resolve merge conflicts with changes to the
+DownloadButton class that made it into `master`.
+
+This rebase can be performed using the `--rebase-merges` option.
+It will generate a todo list looking like this:
+
+------------
+label onto
+
+# Branch: refactor-button
+reset onto
+pick 123456 Extract a generic Button class from the DownloadButton one
+pick 654321 Use the Button class for all buttons
+label refactor-button
+
+# Branch: report-a-bug
+reset refactor-button # Use the Button class for all buttons
+pick abcdef Add the feedback button
+label report-a-bug
+
+reset onto
+merge -C a1b2c3 refactor-button # Merge 'refactor-button'
+merge -C 6f5e4d report-a-bug # Merge 'report-a-bug'
+------------
+
+In contrast to a regular interactive rebase, there are `label`, `reset`
+and `merge` commands in addition to `pick` ones.
+
+The `label` command associates a label with the current HEAD when that
+command is executed. These labels are created as worktree-local refs
+(`refs/rewritten/<label>`) that will be deleted when the rebase
+finishes. That way, rebase operations in multiple worktrees linked to
+the same repository do not interfere with one another. If the `label`
+command fails, it is rescheduled immediately, with a helpful message how
+to proceed.
+
+The `reset` command resets the HEAD, index and worktree to the specified
+revision. It is isimilar to an `exec git reset --hard <label>`, but
+refuses to overwrite untracked files. If the `reset` command fails, it is
+rescheduled immediately, with a helpful message how to edit the todo list
+(this typically happens when a `reset` command was inserted into the todo
+list manually and contains a typo).
+
+The `merge` command will merge the specified revision into whatever is
+HEAD at that time. With `-C <original-commit>`, the commit message of
+the specified merge commit will be used. When the `-C` is changed to
+a lower-case `-c`, the message will be opened in an editor after a
+successful merge so that the user can edit the message.
+
+If a `merge` command fails for any reason other than merge conflicts (i.e.
+when the merge operation did not even start), it is rescheduled immediately.
+
+At this time, the `merge` command will *always* use the `recursive`
+merge strategy, with no way to choose a different one. To work around
+this, an `exec` command can be used to call `git merge` explicitly,
+using the fact that the labels are worktree-local refs (the ref
+`refs/rewritten/onto` would correspond to the label `onto`, for example).
+
+Note: the first command (`label onto`) labels the revision onto which
+the commits are rebased; The name `onto` is just a convention, as a nod
+to the `--onto` option.
+
+It is also possible to introduce completely new merge commits from scratch
+by adding a command of the form `merge <merge-head>`. This form will
+generate a tentative commit message and always open an editor to let the
+user edit it. This can be useful e.g. when a topic branch turns out to
+address more than a single concern and wants to be split into two or
+even more topic branches. Consider this todo list:
+
+------------
+pick 192837 Switch from GNU Makefiles to CMake
+pick 5a6c7e Document the switch to CMake
+pick 918273 Fix detection of OpenSSL in CMake
+pick afbecd http: add support for TLS v1.3
+pick fdbaec Fix detection of cURL in CMake on Windows
+------------
+
+The one commit in this list that is not related to CMake may very well
+have been motivated by working on fixing all those bugs introduced by
+switching to CMake, but it addresses a different concern. To split this
+branch into two topic branches, the todo list could be edited like this:
+
+------------
+label onto
+
+pick afbecd http: add support for TLS v1.3
+label tlsv1.3
+
+reset onto
+pick 192837 Switch from GNU Makefiles to CMake

+pick fdbaec Fix detection of cURL in CMake on Windows

+`working-tree-encoding`
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git recognizes files encoded in ASCII or one of its supersets (e.g.
+UTF-8, ISO-8859-1, ...) as text files. Files encoded in certain other
+encodings (e.g. UTF-16) are interpreted as binary and consequently
+built-in Git text processing tools (e.g. 'git diff') as well as most Git
+web front ends do not visualize the contents of these files by default.
+
+In these cases you can tell Git the encoding of a file in the working
+directory with the `working-tree-encoding` attribute. If a file with this
+attribute is added to Git, then Git reencodes the content from the
+specified encoding to UTF-8. Finally, Git stores the UTF-8 encoded
+content in its internal data structure (called "the index"). On checkout
+the content is reencoded back to the specified encoding.
+
+Please note that using the `working-tree-encoding` attribute may have a
+number of pitfalls:
+
+- Alternative Git implementations (e.g. JGit or libgit2) and older Git
+ versions (as of March 2018) do not support the `working-tree-encoding`
+ attribute. If you decide to use the `working-tree-encoding` attribute
+ in your repository, then it is strongly recommended to ensure that all
+ clients working with the repository support it.
+
+ For example, Microsoft Visual Studio resources files (`*.rc`) or
+ PowerShell script files (`*.ps1`) are sometimes encoded in UTF-16.
+ If you declare `*.ps1` as files as UTF-16 and you add `foo.ps1` with
+ a `working-tree-encoding` enabled Git client, then `foo.ps1` will be
+ stored as UTF-8 internally. A client without `working-tree-encoding`
+ support will checkout `foo.ps1` as UTF-8 encoded file. This will
+ typically cause trouble for the users of this file.
+
+ If a Git client, that does not support the `working-tree-encoding`
+ attribute, adds a new file `bar.ps1`, then `bar.ps1` will be
+ stored "as-is" internally (in this example probably as UTF-16).
+ A client with `working-tree-encoding` support will interpret the
+ internal contents as UTF-8 and try to convert it to UTF-16 on checkout.
+ That operation will fail and cause an error.
+
+- Reencoding content to non-UTF encodings can cause errors as the
+ conversion might not be UTF-8 round trip safe. If you suspect your
+ encoding to not be round trip safe, then add it to
+ `core.checkRoundtripEncoding` to make Git check the round trip
+ encoding (see linkgit:git-config[1]). SHIFT-JIS (Japanese character
+ set) is known to have round trip issues with UTF-8 and is checked by
+ default.
+
+- Reencoding content requires resources that might slow down certain
+ Git operations (e.g 'git checkout' or 'git add').
+
+Use the `working-tree-encoding` attribute only if you cannot store a file
+in UTF-8 encoding and if you want Git to be able to process the content
+as text.
+
+As an example, use the following attributes if your '*.ps1' files are
+UTF-16 encoded with byte order mark (BOM) and you want Git to perform
+automatic line ending conversion based on your platform.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16
+------------------------
+
+Use the following attributes if your '*.ps1' files are UTF-16 little
+endian encoded without BOM and you want Git to use Windows line endings
+in the working directory. Please note, it is highly recommended to
+explicitly define the line endings with `eol` if the `working-tree-encoding`
+attribute is used to avoid ambiguity.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16LE eol=CRLF
+------------------------
+
+You can get a list of all available encodings on your platform with the
+following command:
+
+------------------------
+iconv --list
+------------------------
+
+If you do not know the encoding of a file, then you can use the `file`
+command to guess the encoding:

+Git commit graph format
+=======================
+
+The Git commit graph stores a list of commit OIDs and some associated
+metadata, including:
+
+- The generation number of the commit. Commits with no parents have
+ generation number 1; commits with parents have generation number
+ one more than the maximum generation number of its parents. We
+ reserve zero as special, and can be used to mark a generation
+ number invalid or as "not computed".
+
+- The root tree OID.
+
+- The commit date.
+
+- The parents of the commit, stored using positional references within
+ the graph file.
+
+These positional references are stored as unsigned 32-bit integers
+corresponding to the array position withing the list of commit OIDs. We
+use the most-significant bit for special purposes, so we can store at most
+(1 << 31) - 1 (around 2 billion) commits.
+
+== Commit graph files have the following format:
+
+In order to allow extensions that add extra data to the graph, we organize
+the body into "chunks" and provide a binary lookup table at the beginning
+of the body. The header includes certain values, such as number of chunks
+and hash type.
+
+All 4-byte numbers are in network order.
+
+HEADER:
+
+ 4-byte signature:
+ The signature is: {'C', 'G', 'P', 'H'}
+
+ 1-byte version number:
+ Currently, the only valid version is 1.
+
+ 1-byte Hash Version (1 = SHA-1)
+ We infer the hash length (H) from this value.
+
+ 1-byte number (C) of "chunks"
+
+ 1-byte (reserved for later use)
+ Current clients should ignore this value.
+
+CHUNK LOOKUP:
+
+ (C + 1) * 12 bytes listing the table of contents for the chunks:
+ First 4 bytes describe the chunk id. Value 0 is a terminating label.
+ Other 8 bytes provide the byte-offset in current file for chunk to
+ start. (Chunks are ordered contiguously in the file, so you can infer
+ the length using the next chunk position if necessary.) Each chunk
+ ID appears at most once.
+
+ The remaining data in the body is described one chunk at a time, and
+ these chunks may be given in any order. Chunks are required unless
+ otherwise specified.
+
+CHUNK DATA:
+
+ OID Fanout (ID: {'O', 'I', 'D', 'F'}) (256 * 4 bytes)
+ The ith entry, F[i], stores the number of OIDs with first
+ byte at most i. Thus F[255] stores the total
+ number of commits (N).
+
+ OID Lookup (ID: {'O', 'I', 'D', 'L'}) (N * H bytes)
+ The OIDs for all commits in the graph, sorted in ascending order.
+
+ Commit Data (ID: {'C', 'G', 'E', 'T' }) (N * (H + 16) bytes)
+ * The first H bytes are for the OID of the root tree.
+ * The next 8 bytes are for the positions of the first two parents
+ of the ith commit. Stores value 0xffffffff if no parent in that
+ position. If there are more than two parents, the second value
+ has its most-significant bit on and the other bits store an array
+ position into the Large Edge List chunk.
+ * The next 8 bytes store the generation number of the commit and
+ the commit time in seconds since EPOCH. The generation number
+ uses the higher 30 bits of the first 4 bytes, while the commit
+ time uses the 32 bits of the second 4 bytes, along with the lowest
+ 2 bits of the lowest byte, storing the 33rd and 34th bit of the
+ commit time.
+
+ Large Edge List (ID: {'E', 'D', 'G', 'E'}) [Optional]
+ This list of 4-byte values store the second through nth parents for
+ all octopus merges. The second parent value in the commit data stores
+ an array position within this list along with the most-significant bit
+ on. Starting at that array position, iterate through this list of commit
+ positions for the parents until reaching a value with the most-significant
+ bit on. The other bits correspond to the position of the last parent.

+Git Commit Graph Design Notes
+=============================
+
+Git walks the commit graph for many reasons, including:
+
+1. Listing and filtering commit history.
+2. Computing merge bases.
+
+These operations can become slow as the commit count grows. The merge
+base calculation shows up in many user-facing commands, such as 'merge-base'
+or 'status' and can take minutes to compute depending on history shape.
+
+There are two main costs here:
+
+1. Decompressing and parsing commits.
+2. Walking the entire graph to satisfy topological order constraints.
+
+The commit graph file is a supplemental data structure that accelerates
+commit graph walks. If a user downgrades or disables the 'core.commitGraph'
+config setting, then the existing ODB is sufficient. The file is stored
+as "commit-graph" either in the .git/objects/info directory or in the info
+directory of an alternate.
+
+The commit graph file stores the commit graph structure along with some
+extra metadata to speed up graph walks. By listing commit OIDs in lexi-
+cographic order, we can identify an integer position for each commit and
+refer to the parents of a commit using those integer positions. We use
+binary search to find initial commits and then use the integer positions
+for fast lookups during the walk.
+
+A consumer may load the following info for a commit from the graph:
+
+1. The commit OID.
+2. The list of parents, along with their integer position.
+3. The commit date.
+4. The root tree OID.
+5. The generation number (see definition below).
+
+Values 1-4 satisfy the requirements of parse_commit_gently().
+
+Define the "generation number" of a commit recursively as follows:
+
+ * A commit with no parents (a root commit) has generation number one.
+
+ * A commit with at least one parent has generation number one more than
+ the largest generation number among its parents.
+
+Equivalently, the generation number of a commit A is one more than the
+length of a longest path from A to a root commit. The recursive definition
+is easier to use for computation and observing the following property:
+
+ If A and B are commits with generation numbers N and M, respectively,
+ and N <= M, then A cannot reach B. That is, we know without searching
+ that B is not an ancestor of A because it is further from a root commit
+ than A.
+
+ Conversely, when checking if A is an ancestor of B, then we only need
+ to walk commits until all commits on the walk boundary have generation
+ number at most N. If we walk commits using a priority queue seeded by
+ generation numbers, then we always expand the boundary commit with highest
+ generation number and can easily detect the stopping condition.
+
+This property can be used to significantly reduce the time it takes to
+walk commits and determine topological relationships. Without generation
+numbers, the general heuristic is the following:
+
+ If A and B are commits with commit time X and Y, respectively, and
+ X < Y, then A _probably_ cannot reach B.
+
+This heuristic is currently used whenever the computation is allowed to
+violate topological relationships due to clock skew (such as "git log"
+with default order), but is not used when the topological order is
+required (such as merge base calculations, "git log --graph").
+
+In practice, we expect some commits to be created recently and not stored
+in the commit graph. We can treat these commits as having "infinite"
+generation number and walk until reaching commits with known generation
+number.
+
+Design Details
+--------------
+
+- The commit graph file is stored in a file named 'commit-graph' in the
+ .git/objects/info directory. This could be stored in the info directory
+ of an alternate.
+
+- The core.commitGraph config setting must be on to consume graph files.
+
+- The file format includes parameters for the object ID hash function,
+ so a future change of hash algorithm does not require a change in format.
+
+Future Work
+-----------
+
+- The commit graph feature currently does not honor commit grafts. This can
+ be remedied by duplicating or refactoring the current graft logic.
+
+- The 'commit-graph' subcommand does not have a "verify" mode that is
+ necessary for integration with fsck.
+
+- The file format includes room for precomputed generation numbers. These
+ are not currently computed, so all generation numbers will be marked as
+ 0 (or "uncomputed"). A later patch will include this calculation.
+
+- After computing and storing generation numbers, we must make graph
+ walks aware of generation numbers to gain the performance benefits they
+ enable. This will mostly be accomplished by swapping a commit-date-ordered
+ priority queue with one ordered by generation number. The following
+ operations are important candidates:
+
+ - paint_down_to_common()
+ - 'log --topo-order'
+
+- Currently, parse_commit_gently() requires filling in the root tree
+ object for a commit. This passes through lookup_tree() and consequently
+ lookup_object(). Also, it calls lookup_commit() when loading the parents.
+ These method calls check the ODB for object existence, even if the
+ consumer does not need the content. For example, we do not need the
+ tree contents when computing merge bases. Now that commit parsing is
+ removed from the computation time, these lookup operations are the
+ slowest operations keeping graph walks from being fast. Consider
+ loading these objects without verifying their existence in the ODB and
+ only loading them fully when consumers need them. Consider a method
+ such as "ensure_tree_loaded(commit)" that fully loads a tree before
+ using commit->tree.
+
+- The current design uses the 'commit-graph' subcommand to generate the graph.
+ When this feature stabilizes enough to recommend to most users, we should
+ add automatic graph writes to common operations that create many commits.
+ For example, one could compute a graph on 'clone', 'fetch', or 'repack'
+ commands.
+
+- A server could provide a commit graph file as part of the network protocol
+ to avoid extra calculations by clients. This feature is only of benefit if
+ the user is willing to trust the file, because verifying the file is correct
+ is as hard as computing it from scratch.

+=== Object types

+- OBJ_TREE (2)
+- OBJ_BLOB (3)
+- OBJ_TAG (4)
+- OBJ_OFS_DELTA (6)
+- OBJ_REF_DELTA (7)
+
+Type 5 is reserved for future expansion. Type 0 is invalid.
+
+=== Deltified representation
+
+Conceptually there are only four object types: commit, tree, tag and
+blob. However to save space, an object could be stored as a "delta" of
+another "base" object. These representations are assigned new types
+ofs-delta and ref-delta, which is only valid in a pack file.
+
+Both ofs-delta and ref-delta store the "delta" to be applied to
+another object (called 'base object') to reconstruct the object. The
+difference between them is, ref-delta directly encodes 20-byte base
+object name. If the base object is in the same pack, ofs-delta encodes
+the offset of the base object in the pack instead.
+
+The base object could also be deltified if it's in the same pack.
+Ref-delta can also refer to an object outside the pack (i.e. the
+so-called "thin pack"). When stored on disk however, the pack should
+be self contained to avoid cyclic dependency.
+
+The delta data is a sequence of instructions to reconstruct an object
+from the base object. If the base object is deltified, it must be
+converted to canonical form first. Each instruction appends more and
+more data to the target object until it's complete. There are two
+supported instructions so far: one for copy a byte range from the
+source object and one for inserting new data embedded in the
+instruction itself.
+
+Each instruction has variable length. Instruction type is determined
+by the seventh bit of the first octet. The following diagrams follow
+the convention in RFC 1951 (Deflate compressed data format).
+
+==== Instruction to copy from base object
+
+ +----------+---------+---------+---------+---------+-------+-------+-------+
+ | 1xxxxxxx | offset1 | offset2 | offset3 | offset4 | size1 | size2 | size3 |
+ +----------+---------+---------+---------+---------+-------+-------+-------+
+
+This is the instruction format to copy a byte range from the source
+object. It encodes the offset to copy from and the number of bytes to
+copy. Offset and size are in little-endian order.
+
+All offset and size bytes are optional. This is to reduce the
+instruction size when encoding small offsets or sizes. The first seven
+bits in the first octet determines which of the next seven octets is
+present. If bit zero is set, offset1 is present. If bit one is set
+offset2 is present and so on.
+
+Note that a more compact instruction does not change offset and size
+encoding. For example, if only offset2 is omitted like below, offset3
+still contains bits 16-23. It does not become offset2 and contains
+bits 8-15 even if it's right next to offset1.
+
+ +----------+---------+---------+
+ | 10000101 | offset1 | offset3 |
+ +----------+---------+---------+
+
+In its most compact form, this instruction only takes up one byte
+(0x80) with both offset and size omitted, which will have default
+values zero. There is another exception: size zero is automatically
+converted to 0x10000.
+
+==== Instruction to add new data
+
+ +----------+============+
+ | 0xxxxxxx | data |
+ +----------+============+
+
+This is the instruction to construct target object without the base
+object. The following data is appended to the target object. The first
+seven bits of the first octet determines the size of data in
+bytes. The size must be non-zero.

+ Git Wire Protocol, Version 2
+==============================
+
+This document presents a specification for a version 2 of Git's wire
+protocol. Protocol v2 will improve upon v1 in the following ways:
+
+ * Instead of multiple service names, multiple commands will be
+ supported by a single service
+ * Easily extendable as capabilities are moved into their own section
+ of the protocol, no longer being hidden behind a NUL byte and
+ limited by the size of a pkt-line
+ * Separate out other information hidden behind NUL bytes (e.g. agent
+ string as a capability and symrefs can be requested using 'ls-refs')
+ * Reference advertisement will be omitted unless explicitly requested
+ * ls-refs command to explicitly request some refs
+ * Designed with http and stateless-rpc in mind. With clear flush
+ semantics the http remote helper can simply act as a proxy
+
+In protocol v2 communication is command oriented. When first contacting a
+server a list of capabilities will advertised. Some of these capabilities
+will be commands which a client can request be executed. Once a command
+has completed, a client can reuse the connection and request that other
+commands be executed.
+
+ Packet-Line Framing
+---------------------
+
+All communication is done using packet-line framing, just as in v1. See
+`Documentation/technical/pack-protocol.txt` and
+`Documentation/technical/protocol-common.txt` for more information.
+
+In protocol v2 these special packets will have the following semantics:
+
+ * '0000' Flush Packet (flush-pkt) - indicates the end of a message
+ * '0001' Delimiter Packet (delim-pkt) - separates sections of a message
+
+ Initial Client Request
+------------------------
+
+In general a client can request to speak protocol v2 by sending
+`version=2` through the respective side-channel for the transport being
+used which inevitably sets `GIT_PROTOCOL`. More information can be
+found in `pack-protocol.txt` and `http-protocol.txt`. In all cases the
+response from the server is the capability advertisement.
+
+ Git Transport
+~~~~~~~~~~~~~~~
+
+When using the git:// transport, you can request to use protocol v2 by
+sending "version=2" as an extra parameter:
+
+ 003egit-upload-pack /project.git\0host=myserver.com\0\0version=2\0
+
+ SSH and File Transport
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using either the ssh:// or file:// transport, the GIT_PROTOCOL
+environment variable must be set explicitly to include "version=2".
+
+ HTTP Transport
+~~~~~~~~~~~~~~~~
+
+When using the http:// or https:// transport a client makes a "smart"
+info/refs request as described in `http-protocol.txt` and requests that
+v2 be used by supplying "version=2" in the `Git-Protocol` header.
+
+ C: Git-Protocol: version=2
+ C:
+ C: GET $GIT_URL/info/refs?service=git-upload-pack HTTP/1.0
+
+A v2 server would reply:
+
+ S: 200 OK
+ S: <Some headers>
+ S: ...
+ S:
+ S: 000eversion 2\n
+ S: <capability-advertisement>
+
+Subsequent requests are then made directly to the service
+`$GIT_URL/git-upload-pack`. (This works the same for git-receive-pack).
+
+ Capability Advertisement
+--------------------------
+
+A server which decides to communicate (based on a request from a client)
+using protocol version 2, notifies the client by sending a version string
+in its initial response followed by an advertisement of its capabilities.
+Each capability is a key with an optional value. Clients must ignore all
+unknown keys. Semantics of unknown values are left to the definition of
+each key. Some capabilities will describe commands which can be requested
+to be executed by the client.
+
+ capability-advertisement = protocol-version
+ capability-list
+ flush-pkt
+
+ protocol-version = PKT-LINE("version 2" LF)
+ capability-list = *capability
+ capability = PKT-LINE(key[=value] LF)
+
+ key = 1*(ALPHA | DIGIT | "-_")
+ value = 1*(ALPHA | DIGIT | " -_.,?\/{}[]()<>!@#$%^&*+=:;")
+
+ Command Request
+-----------------
+
+After receiving the capability advertisement, a client can then issue a
+request to select the command it wants with any particular capabilities
+or arguments. There is then an optional section where the client can
+provide any command specific parameters or queries. Only a single
+command can be requested at a time.
+
+ request = empty-request | command-request
+ empty-request = flush-pkt
+ command-request = command
+ capability-list
+ [command-args]
+ flush-pkt
+ command = PKT-LINE("command=" key LF)
+ command-args = delim-pkt
+ *command-specific-arg
+
+ command-specific-args are packet line framed arguments defined by
+ each individual command.
+
+The server will then check to ensure that the client's request is
+comprised of a valid command as well as valid capabilities which were
+advertised. If the request is valid the server will then execute the
+command. A server MUST wait till it has received the client's entire
+request before issuing a response. The format of the response is
+determined by the command being executed, but in all cases a flush-pkt
+indicates the end of the response.
+
+When a command has finished, and the client has received the entire
+response from the server, a client can either request that another
+command be executed or can terminate the connection. A client may
+optionally send an empty request consisting of just a flush-pkt to
+indicate that no more requests will be made.
+
+ Capabilities
+--------------
+
+There are two different types of capabilities: normal capabilities,
+which can be used to to convey information or alter the behavior of a
+request, and commands, which are the core actions that a client wants to
+perform (fetch, push, etc).
+
+Protocol version 2 is stateless by default. This means that all commands
+must only last a single round and be stateless from the perspective of the
+server side, unless the client has requested a capability indicating that
+state should be maintained by the server. Clients MUST NOT require state
+management on the server side in order to function correctly. This
+permits simple round-robin load-balancing on the server side, without
+needing to worry about state management.
+
+ agent
+~~~~~~~
+
+The server can advertise the `agent` capability with a value `X` (in the
+form `agent=X`) to notify the client that the server is running version
+`X`. The client may optionally send its own agent string by including
+the `agent` capability with a value `Y` (in the form `agent=Y`) in its
+request to the server (but it MUST NOT do so if the server did not
+advertise the agent capability). The `X` and `Y` strings may contain any
+printable ASCII characters except space (i.e., the byte range 32 < x <
+127), and are typically of the form "package/version" (e.g.,
+"git/1.8.3.1"). The agent strings are purely informative for statistics
+and debugging purposes, and MUST NOT be used to programmatically assume
+the presence or absence of particular features.
+
+ ls-refs
+~~~~~~~~~
+
+`ls-refs` is the command used to request a reference advertisement in v2.
+Unlike the current reference advertisement, ls-refs takes in arguments
+which can be used to limit the refs sent from the server.
+
+Additional features not supported in the base command will be advertised
+as the value of the command in the capability advertisement in the form
+of a space separated list of features: "<command>=<feature 1> <feature 2>"
+
+ls-refs takes in the following arguments:
+
+ symrefs
+ In addition to the object pointed by it, show the underlying ref
+ pointed by it when showing a symbolic ref.
+ peel
+ Show peeled tags.
+ ref-prefix <prefix>
+ When specified, only references having a prefix matching one of
+ the provided prefixes are displayed.
+
+The output of ls-refs is as follows:
+
+ output = *ref
+ flush-pkt
+ ref = PKT-LINE(obj-id SP refname *(SP ref-attribute) LF)
+ ref-attribute = (symref | peeled)
+ symref = "symref-target:" symref-target
+ peeled = "peeled:" obj-id
+
+ fetch
+~~~~~~~
+
+`fetch` is the command used to fetch a packfile in v2. It can be looked
+at as a modified version of the v1 fetch where the ref-advertisement is
+stripped out (since the `ls-refs` command fills that role) and the
+message format is tweaked to eliminate redundancies and permit easy
+addition of future extensions.
+
+Additional features not supported in the base command will be advertised
+as the value of the command in the capability advertisement in the form
+of a space separated list of features: "<command>=<feature 1> <feature 2>"
+
+A `fetch` request can take the following arguments:
+
+ want <oid>
+ Indicates to the server an object which the client wants to
+ retrieve. Wants can be anything and are not limited to
+ advertised objects.
+
+ have <oid>
+ Indicates to the server an object which the client has locally.
+ This allows the server to make a packfile which only contains
+ the objects that the client needs. Multiple 'have' lines can be
+ supplied.
+
+ done
+ Indicates to the server that negotiation should terminate (or
+ not even begin if performing a clone) and that the server should
+ use the information supplied in the request to construct the
+ packfile.
+
+ thin-pack
+ Request that a thin pack be sent, which is a pack with deltas
+ which reference base objects not contained within the pack (but
+ are known to exist at the receiving end). This can reduce the
+ network traffic significantly, but it requires the receiving end
+ to know how to "thicken" these packs by adding the missing bases
+ to the pack.
+
+ no-progress
+ Request that progress information that would normally be sent on
+ side-band channel 2, during the packfile transfer, should not be
+ sent. However, the side-band channel 3 is still used for error
+ responses.
+
+ include-tag
+ Request that annotated tags should be sent if the objects they
+ point to are being sent.
+
+ ofs-delta
+ Indicate that the client understands PACKv2 with delta referring
+ to its base by position in pack rather than by an oid. That is,
+ they can read OBJ_OFS_DELTA (ake type 6) in a packfile.
+
+If the 'shallow' feature is advertised the following arguments can be
+included in the clients request as well as the potential addition of the
+'shallow-info' section in the server's response as explained below.
+
+ shallow <oid>
+ A client must notify the server of all commits for which it only
+ has shallow copies (meaning that it doesn't have the parents of
+ a commit) by supplying a 'shallow <oid>' line for each such
+ object so that the server is aware of the limitations of the
+ client's history. This is so that the server is aware that the
+ client may not have all objects reachable from such commits.
+
+ deepen <depth>
+ Requests that the fetch/clone should be shallow having a commit
+ depth of <depth> relative to the remote side.
+
+ deepen-relative
+ Requests that the semantics of the "deepen" command be changed
+ to indicate that the depth requested is relative to the client's
+ current shallow boundary, instead of relative to the requested
+ commits.
+
+ deepen-since <timestamp>
+ Requests that the shallow clone/fetch should be cut at a
+ specific time, instead of depth. Internally it's equivalent to
+ doing "git rev-list --max-age=<timestamp>". Cannot be used with
+ "deepen".
+
+ deepen-not <rev>
+ Requests that the shallow clone/fetch should be cut at a
+ specific revision specified by '<rev>', instead of a depth.
+ Internally it's equivalent of doing "git rev-list --not <rev>".
+ Cannot be used with "deepen", but can be used with
+ "deepen-since".
+
+If the 'filter' feature is advertised, the following argument can be
+included in the client's request:
+
+ filter <filter-spec>
+ Request that various objects from the packfile be omitted
+ using one of several filtering techniques. These are intended
+ for use with partial clone and partial fetch operations. See
+ `rev-list` for possible "filter-spec" values.
+
+The response of `fetch` is broken into a number of sections separated by
+delimiter packets (0001), with each section beginning with its section
+header.
+
+ output = *section
+ section = (acknowledgments | shallow-info | packfile)
+ (flush-pkt | delim-pkt)
+
+ acknowledgments = PKT-LINE("acknowledgments" LF)
+ (nak | *ack)
+ (ready)
+ ready = PKT-LINE("ready" LF)
+ nak = PKT-LINE("NAK" LF)
+ ack = PKT-LINE("ACK" SP obj-id LF)
+
+ shallow-info = PKT-LINE("shallow-info" LF)
+ *PKT-LINE((shallow | unshallow) LF)
+ shallow = "shallow" SP obj-id
+ unshallow = "unshallow" SP obj-id
+
+ packfile = PKT-LINE("packfile" LF)
+ *PKT-LINE(%x01-03 *%x00-ff)
+
+ acknowledgments section
+ * If the client determines that it is finished with negotiations
+ by sending a "done" line, the acknowledgments sections MUST be
+ omitted from the server's response.
+
+ * Always begins with the section header "acknowledgments"
+
+ * The server will respond with "NAK" if none of the object ids sent
+ as have lines were common.
+
+ * The server will respond with "ACK obj-id" for all of the
+ object ids sent as have lines which are common.
+
+ * A response cannot have both "ACK" lines as well as a "NAK"
+ line.
+
+ * The server will respond with a "ready" line indicating that
+ the server has found an acceptable common base and is ready to
+ make and send a packfile (which will be found in the packfile
+ section of the same response)
+
+ * If the server has found a suitable cut point and has decided
+ to send a "ready" line, then the server can decide to (as an
+ optimization) omit any "ACK" lines it would have sent during
+ its response. This is because the server will have already
+ determined the objects it plans to send to the client and no
+ further negotiation is needed.
+
+ shallow-info section
+ * If the client has requested a shallow fetch/clone, a shallow
+ client requests a fetch or the server is shallow then the
+ server's response may include a shallow-info section. The
+ shallow-info section will be included if (due to one of the
+ above conditions) the server needs to inform the client of any
+ shallow boundaries or adjustments to the clients already
+ existing shallow boundaries.
+
+ * Always begins with the section header "shallow-info"
+
+ * If a positive depth is requested, the server will compute the
+ set of commits which are no deeper than the desired depth.
+
+ * The server sends a "shallow obj-id" line for each commit whose
+ parents will not be sent in the following packfile.

these commits have no parents.
*********************************************************
-The basic idea is to write the SHA-1s of shallow commits into
-$GIT_DIR/shallow, and handle its contents like the contents
-of $GIT_DIR/info/grafts (with the difference that shallow
-cannot contain parent information).
-
-This information is stored in a new file instead of grafts, or
-even the config, since the user should not touch that file
-at all (even throughout development of the shallow clone, it
-was never manually edited!).
+$GIT_DIR/shallow lists commit object names and tells Git to
+pretend as if they are root commits (e.g. "git log" traversal
+stops after showing them; "git fsck" does not complain saying
+the commits listed on their "parent" lines do not exist).
Each line contains exactly one SHA-1. When read, a commit_graft
will be constructed, which has nr_parent < 0 to make it easier
to discern from user provided grafts.
+Note that the shallow feature could not be changed easily to
+use replace refs: a commit containing a `mergetag` is not allowed
+to be replaced, not even by a root commit. Such a commit can be
+made shallow, though. Also, having a `shallow` file explicitly
+listing all the commits made shallow makes it a *lot* easier to
+do shallow-specific things such as to deepen the history.
+
Since fsck-objects relies on the library to read the objects,
it honours shallow commits automatically.
