+Git 2.34 Release Notes
+======================
+
+Updates since Git 2.33
+----------------------
+
+UI, Workflows & Features
+
+ * Pathname expansion (like "~username/") learned a way to specify a
+ location relative to Git installation (e.g. its $sharedir which is
+ $(prefix)/share), with "%(prefix)".
+
+ * Use `ort` instead of `recursive` as the default merge strategy.
+
+ * The userdiff pattern for "java" language has been updated.
+
+ * "git rebase" by default skips changes that are equivalent to
+ commits that are already in the history the branch is rebased onto;
+ give messages when this happens to let the users be aware of
+ skipped commits, and also teach them how to tell "rebase" to keep
+ duplicated changes.
+
+ * The advice message that "git cherry-pick" gives when it asks
+ conflicted replay of a commit to be resolved by the end user has
+ been updated.
+
+ * After "git clone --recurse-submodules", all submodules are cloned
+ but they are not by default recursed into by other commands. With
+ submodule.stickyRecursiveClone configuration set, submodule.recurse
+ configuration is set to true in a repository created by "clone"
+ with "--recurse-submodules" option.
+
+ * The logic for auto-correction of misspelt subcommands learned to go
+ interactive when the help.autocorrect configuration variable is set
+ to 'prompt'.
+
+ * "git maintenance" scheduler learned to use systemd timers as a
+ possible backend.
+
+ * "git diff --submodule=diff" showed failure from run_command() when
+ trying to run diff inside a submodule, when the user manually
+ removes the submodule directory.
+
+ * "git bundle unbundle" learned to show progress display.
+
+ * In cone mode, the sparse-index code path learned to remove ignored
+ files (like build artifacts) outside the sparse cone, allowing the
+ entire directory outside the sparse cone to be removed, which is
+ especially useful when the sparse patterns change.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * "git bisect" spawned "git show-branch" only to pretty-print the
+ title of the commit after checking out the next version to be
+ tested; this has been rewritten in C.
+
+ * "git add" can work better with the sparse index.
+
+ * Support for ancient versions of cURL library (pre 7.19.4) has been
+ dropped.
+
+ * A handful of tests that assumed implementation details of files
+ backend for refs have been cleaned up.
+
+ * trace2 logs learned to show parent process name to see in what
+ context Git was invoked.
+
+ * Loading of ref tips to prepare for common ancestry negotiation in
+ "git fetch-pack" has been optimized by taking advantage of the
+ commit graph when available.
+
+ * Remind developers that the userdiff patterns should be kept simple
+ and permissive, assuming that the contents they apply are always
+ syntactically correct.
+
+ * The current implementation of GIT_TEST_FAIL_PREREQS is broken in
+ that checking for the lack of a prerequisite would not work. Avoid
+ the use of "if ! test_have_prereq X" in a test script.
+
+ * The revision traversal API has been optimized by taking advantage
+ of the commit-graph, when available, to determine if a commit is
+ reachable from any of the existing refs.

DESCRIPTION
-----------
-Some workflows require that one or more branches of development on one
-machine be replicated on another machine, but the two machines cannot
-be directly connected, and therefore the interactive Git protocols (git,
-ssh, http) cannot be used.
+Create, unpack, and manipulate "bundle" files. Bundles are used for
+the "offline" transfer of Git objects without an active "server"
+sitting on the other side of the network connection.
-The 'git bundle' command packages objects and references in an archive
-at the originating machine, which can then be imported into another
-repository using 'git fetch', 'git pull', or 'git clone',
-after moving the archive by some means (e.g., by sneakernet).
+They can be used to create both incremental and full backups of a
+repository, and to relay the state of the references in one repository
+to another.
-As no
-direct connection between the repositories exists, the user must specify a
-basis for the bundle that is held by the destination repository: the
-bundle assumes that all objects in the basis are already in the
-destination repository.
+Git commands that fetch or otherwise "read" via protocols such as
+`ssh://` and `https://` can also operate on bundle files. It is
+possible linkgit:git-clone[1] a new repository from a bundle, to use
+linkgit:git-fetch[1] to fetch from one, and to list the references
+contained within it with linkgit:git-ls-remote[1]. There's no
+corresponding "write" support, i.e.a 'git push' into a bundle is not
+supported.
+
+See the "EXAMPLES" section below for examples of how to use bundles.
+
+BUNDLE FORMAT
+-------------
+
+Bundles are `.pack` files (see linkgit:git-pack-objects[1]) with a
+header indicating what references are contained within the bundle.
+
+Like the the packed archive format itself bundles can either be
+self-contained, or be created using exclusions.
+See the "OBJECT PREREQUISITES" section below.
+
+Bundles created using revision exclusions are "thin packs" created
+using the `--thin` option to linkgit:git-pack-objects[1], and
+unbundled using the `--fix-thin` option to linkgit:git-index-pack[1].
+
+There is no option to create a "thick pack" when using revision
+exclusions, users should not be concerned about the difference. By
+using "thin packs" bundles created using exclusions are smaller in
+size. That they're "thin" under the hood is merely noted here as a
+curiosity, and as a reference to other documentation
+
+See link:technical/bundle-format.html[the `bundle-format`
+documentation] for more details and the discussion of "thin pack" in
+link:technical/pack-format.html[the pack format documentation] for
+further details.

SPECIFYING REFERENCES
---------------------
-'git bundle' will only package references that are shown by
-'git show-ref': this includes heads, tags, and remote heads. References
-such as `master~1` cannot be packaged, but are perfectly suitable for
-defining the basis. More than one reference may be packaged, and more
-than one basis can be specified. The objects packaged are those not
-contained in the union of the given bases. Each basis can be
-specified explicitly (e.g. `^master~10`), or implicitly (e.g.
-`master~10..master`, `--since=10.days.ago master`).
+Revisions must accompanied by reference names to be packaged in a
+bundle.
+
+More than one reference may be packaged, and more than one set of prerequisite objects can
+be specified. The objects packaged are those not contained in the
+union of the prerequisites.
+
+The 'git bundle create' command resolves the reference names for you
+using the same rules as `git rev-parse --abbrev-ref=loose`. Each
+prerequisite can be specified explicitly (e.g. `^master~10`), or implicitly
+(e.g. `master~10..master`, `--since=10.days.ago master`).
+
+All of these simple cases are OK (assuming we have a "master" and
+"next" branch):
+
+----------------
+$ git bundle create master.bundle master
+$ echo master | git bundle create master.bundle --stdin
+$ git bundle create master-and-next.bundle master next
+$ (echo master; echo next) | git bundle create master-and-next.bundle --stdin
+----------------
+
+And so are these (and the same but omitted `--stdin` examples):
+
+----------------
+$ git bundle create recent-master.bundle master~10..master
+$ git bundle create recent-updates.bundle master~10..master next~5..next
+----------------
+
+A revision name or a range whose right-hand-side cannot be resolved to
+a reference is not accepted:
+
+----------------
+$ git bundle create HEAD.bundle $(git rev-parse HEAD)
+fatal: Refusing to create empty bundle.
+$ git bundle create master-yesterday.bundle master~10..master~5
+fatal: Refusing to create empty bundle.
+----------------
+
+OBJECT PREREQUISITES
+--------------------
+
+When creating bundles it is possible to create a self-contained bundle
+that can be unbundled in a repository with no common history, as well
+as providing negative revisions to exclude objects needed in the
+earlier parts of the history.
+
+Feeding a revision such as `new` to `git bundle create` will create a
+bundle file that contains all the objects reachable from the revision
+`new`. That bundle can be unbundled in any repository to obtain a full
+history that leads to the revision `new`:
+
+----------------
+$ git bundle create full.bundle new
+----------------
+
+A revision range such as `old..new` will produce a bundle file that
+will require the revision `old` (and any objects reachable from it)
+to exist for the bundle to be "unbundle"-able:
+
+----------------
+$ git bundle create full.bundle old..new
+----------------
+
+A self-contained bundle without any prerequisites can be extracted
+into anywhere, even into an empty repository, or be cloned from
+(i.e., `new`, but not `old..new`).
-It is very important that the basis used be held by the destination.
It is okay to err on the side of caution, causing the bundle file
to contain objects already in the destination, as these are ignored
when unpacking at the destination.
-`git clone` can use any bundle created without negative refspecs
-(e.g., `new`, but not `old..new`).
If you want to match `git clone --mirror`, which would include your
refs such as `refs/remotes/*`, use `--all`.
If you want to provide the same set of refs that a clone directly
from the source repository would get, use `--branches --tags` for
the `<git-rev-list-args>`.
+The 'git bundle verify' command can be used to check whether your
+recipient repository has the required prerequisite commits for a
+bundle.

GIT bitmap v1 format
====================
+== Pack and multi-pack bitmaps
+
+Bitmaps store reachability information about the set of objects in a packfile,
+or a multi-pack index (MIDX). The former is defined obviously, and the latter is
+defined as the union of objects in packs contained in the MIDX.
+
+A bitmap may belong to either one pack, or the repository's multi-pack index (if
+it exists). A repository may have at most one bitmap.
+
+An object is uniquely described by its bit position within a bitmap:
+
+ - If the bitmap belongs to a packfile, the __n__th bit corresponds to
+ the __n__th object in pack order. For a function `offset` which maps
+ objects to their byte offset within a pack, pack order is defined as
+ follows:
+
+ o1 <= o2 <==> offset(o1) <= offset(o2)
+
+ - If the bitmap belongs to a MIDX, the __n__th bit corresponds to the
+ __n__th object in MIDX order. With an additional function `pack` which
+ maps objects to the pack they were selected from by the MIDX, MIDX order
+ is defined as follows:
+
+ o1 <= o2 <==> pack(o1) <= pack(o2) /\ offset(o1) <= offset(o2)
+
+ The ordering between packs is done according to the MIDX's .rev file.
+ Notably, the preferred pack sorts ahead of all other packs.
+
+The on-disk representation (described below) of a bitmap is the same regardless
+of whether or not that bitmap belongs to a packfile or a MIDX. The only
+difference is the interpretation of the bits, which is described above.
+
+Certain bitmap extensions are supported (see: Appendix B). No extensions are
+required for bitmaps corresponding to packfiles. For bitmaps that correspond to
+MIDXs, both the bit-cache and rev-cache extensions are required.

+ * We need more complex parsing in stat_parent_pid() and
+ * parse_proc_stat() below than a dumb fscanf(). That's because while
+ * the statcomm field is surrounded by parentheses, the process itself
+ * is free to insert any arbitrary byte sequence its its name. That
+ * can include newlines, spaces, closing parentheses etc.
+ *
+ * See do_task_stat() in fs/proc/array.c in linux.git, this is in
+ * contrast with the escaped version of the name found in
+ * /proc/%d/status.
+ *
+ * So instead of using fscanf() we'll read N bytes from it, look for
+ * the first "(", and then the last ")", anything in-between is our
+ * process name.
+ *
+ * How much N do we need? On Linux /proc/sys/kernel/pid_max is 2^15 by
+ * default, but it can be raised set to values of up to 2^22. So
+ * that's 7 digits for a PID. We have 2 PIDs in the first four fields
+ * we're interested in, so 2 * 7 = 14.
+ *
+ * We then have 3 spaces between those four values, and we'd like to
+ * get to the space between the 4th and the 5th (the "pgrp" field) to
+ * make sure we read the entire "ppid" field. So that brings us up to
+ * 14 + 3 + 1 = 18. Add the two parentheses around the "comm" value
+ * and it's 20. The "state" value itself is then one character (now at
+ * 21).
+ *
+ * Finally the maximum length of the "comm" name itself is 15
+ * characters, e.g. a setting of "123456789abcdefg" will be truncated
+ * to "123456789abcdef". See PR_SET_NAME in prctl(2). So all in all
+ * we'd need to read 21 + 15 = 36 bytes.
+ *
+ * Let's just read 2^6 (64) instead for good measure. If PID_MAX ever
+ * grows past 2^22 we'll be future-proof. We'll then anchor at the
+ * last ")" we find to locate the parent PID.
