+Git v2.13.7 Release Notes
+=========================
+
+Fixes since v2.13.6
+-------------------
+
+ * Submodule "names" come from the untrusted .gitmodules file, but we
+ blindly append them to $GIT_DIR/modules to create our on-disk repo
+ paths. This means you can do bad things by putting "../" into the
+ name. We now enforce some rules for submodule names which will cause
+ Git to ignore these malicious names (CVE-2018-11235).
+
+ Credit for finding this vulnerability and the proof of concept from
+ which the test script was adapted goes to Etienne Stalmans.
+
+ * It was possible to trick the code that sanity-checks paths on NTFS
+ into reading random piece of memory (CVE-2018-11233).
+
+Credit for fixing for these bugs goes to Jeff King, Johannes
+Schindelin and others.
--- /dev/null
+Git v2.14.4 Release Notes
+=========================
+
+This release is to forward-port the fixes made in the v2.13.7 version
+of Git. See its release notes for details.
* Clarify and enhance documentation for "merge-base --fork-point", as
it was clear what it computed but not why/what for.
+ * This release also contains the fixes made in the v2.13.7 version of
+ Git. See its release notes for details.
+
Also contains various documentation updates and code clean-ups.
--- /dev/null
+Git v2.16.4 Release Notes
+=========================
+
+This release is to forward-port the fixes made in the v2.13.7 version
+of Git. See its release notes for details.
--- /dev/null
+Git v2.17.1 Release Notes
+=========================
+
+Fixes since v2.17
+-----------------
+
+ * This release contains the same fixes made in the v2.13.7 version of
+ Git, covering CVE-2018-11233 and 11235, and forward-ported to
+ v2.14.4, v2.15.2 and v2.16.4 releases. See release notes to
+ v2.13.7 for details.
+
+ * In addition to the above fixes, this release has support on the
+ server side to reject pushes to repositories that attempt to create
+ such problematic .gitmodules file etc. as tracked contents, to help
+ hosting sites protect their customers by preventing malicious
+ contents from spreading.
"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+ * The functionality of "$GIT_DIR/info/grafts" has been superseded by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.
+
+ * "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.
+
Performance, Internal Implementation, Development Support etc.
* 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).
+
+ * Rename detection logic in "diff" family that is used in "merge" 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 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.
+
Also contains various documentation updates and code clean-ups.
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).

+OPERATING MODES
---------------
You can choose whether you want to trust the index file entirely
(using the `--cached` flag) or ask the diff logic to show any files
that don't match the stat state as being "tentatively changed". Both
of these operations are very useful indeed.
-Cached Mode
+CACHED MODE
-----------
If `--cached` is specified, it allows you to ask:
asking yourself "what have I already marked for being committed, and
what's the difference to a previous tree".
-Non-cached Mode
+NON-CACHED MODE
---------------
The "non-cached" mode takes a different approach, and is potentially
the more useful of the two in that what it does can't be emulated with

two blob objects, or changes between two files on disk.
-'git diff' [
--options] [--] [<path>...]::
+'git diff' [options] [--] [<path>...]::
This form is to view the changes you made relative to
the index (staging area for the next commit). In other

stage these changes by using linkgit:git-add[1].
-'git diff' --no-index [--options] [--] [<path>...]::
+'git diff' [options] --no-index [--] <path> <path>::
This form is to compare the given two paths on the

controlled by Git.
-'git diff' [
--options] --cached [<commit>] [--] [<path>...]::

-Limitations
+LIMITATIONS
-----------
Since 'git fast-import' cannot tag trees, you will not be
fastimport.unpackLimit::
See linkgit:git-config[1]
-Performance
+PERFORMANCE
-----------
The design of fast-import allows it to import large projects in a minimum
amount of memory usage and processing time. Assuming the frontend
destination Git repository (due to less IO contention).
-Development Cost
+DEVELOPMENT COST
----------------
A typical frontend for fast-import tends to weigh in at approximately 200
lines of Perl/Python/Ruby code. Most developers have been able to
(use once, and never look back).
-Parallel Operation
+PARALLEL OPERATION
------------------
Like 'git push' or 'git fetch', imports handled by fast-import are safe to
run alongside parallel `git repack -a -d` or `git gc` invocations,
is not necessary for an initial import into an empty repository.
-Technical Discussion
+TECHNICAL DISCUSSION
--------------------
fast-import tracks a set of branches in memory. Any branch can be created
or modified at any point during the import process by sending a
need to perform any costly file update operations when switching
between branches.
-Input Format
+INPUT FORMAT
------------
With the exception of raw file data (which Git does not interpret)
the fast-import input format is text (ASCII) based. This text based
in use, the `done` command is mandatory and marks the end of the
stream.
-Responses To Commands
+RESPONSES TO COMMANDS
---------------------
New objects written by fast-import are not available immediately.
Most fast-import commands have no visible effect until the next
pending output from `progress`, `ls`, `get-mark`, and `cat-blob` before
performing writes to fast-import that might block.
-Crash Reports
+CRASH REPORTS

------------------
There are a number of factors which affect how much memory fast-import

projects with 2,000+ branches and 45,114+ files in a very limited
memory footprint (less than 2.7 MiB per active branch).

+ By default, a rebase will simply drop merge commits from the todo

+ With `--rebase-merges`, the rebase will instead try to preserve
+ the branching structure within the commits that are to be rebased,
+ by recreating the merge commits. Any resolved merge conflicts or
+ manual amendments in these merge commits will have to be
+ resolved/re-applied manually.
++
+By default, or when `no-rebase-cousins` was specified, commits which do not
+have `<upstream>` as direct ancestor will keep their original branch point,
+i.e. commits that would be excluded by gitlink:git-log[1]'s
+`--ancestry-path` option will keep their original ancestry by default. If
+the `rebase-cousins` mode is turned on, such commits are instead rebased
+onto `<upstream>` (or `<onto>`, if specified).
++
+The `--rebase-merges` mode is similar in spirit to `--preserve-merges`, but
+in contrast to that option works well in interactive rebases: commits can be

+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 918273 Fix detection of OpenSSL in CMake
+pick fdbaec Fix detection of cURL in CMake on Windows
+pick 5a6c7e Document the switch to CMake

Examples
--------
- The trailer records 20-byte SHA-1 checksum of all of the above.
+=== Object types
+
+Valid object types are:
+
+- OBJ_COMMIT (1)
+- 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.
+
+==== Reserved instruction
+
+ +----------+============
+ | 00000000 |
+ +----------+============
+
+This is the instruction reserved for future expansion.
+
== Original (version 1) pack-*.idx files have the following format:

Cannot be used with "deepen", but can be used with

+ 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.

*********************************************************
-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.

+ * -----------------
+ * idx.oid is filled up before delta searching starts. idx.crc32 is

+ * generating the index. idx.offset will be both gradually set and
+ * used in writing phase (base objects get offset first, then deltas
+ * refer to them)
+ *
+ * "size" is the uncompressed object size. Compressed size of the raw
+ * data for an object in a pack is not stored anywhere but is computed
+ * and made available when reverse .idx is made. Note that when a
+ * delta is reused, "size" is the uncompressed _delta_ size, not the
+ * canonical one after the delta has been applied.
+ *
+ * "hash" contains a path name hash which is used for sorting the
+ * delta list and also during delta searching. Once prepare_pack()
+ * returns it's no longer needed.
+ *
+ * source pack info
+ * ----------------
+ * The (in_pack, in_pack_offset) tuple contains the location of the
+ * object in the source pack. in_pack_header_size allows quickly
+ * skipping the header and going straight to the zlib stream.
+ *
+ * "type" and "in_pack_type" both describe object type. in_pack_type
+ * may contain a delta type, while type is always the canonical type.
+ *
+ * deltas
+ * ------
+ * Delta links (delta, delta_child and delta_sibling) are created to
+ * reflect that delta graph from the source pack then updated or added
+ * during delta searching phase when we find better deltas.
+ *
+ * delta_child and delta_sibling are last needed in
+ * compute_write_order(). "delta" and "delta_size" must remain valid
+ * at object writing phase in case the delta is not cached.
+ *
+ * If a delta is cached in memory and is compressed, delta_data points
+ * to the data and z_delta_size contains the compressed size. If it's
+ * uncompressed [1], z_delta_size must be zero. delta_size is always
+ * the uncompressed size and must be valid even if the delta is not
+ * cached.
+ *
+ * [1] during try_delta phase we don't bother with compressing because
+ * the delta could be quickly replaced with a better one.

everything up to a certain test.
+Running tests with special setups
+---------------------------------
+
+The whole test suite could be run to test some special features
+that cannot be easily covered by a few specific test cases. These
+could be enabled by running the test suite with correct GIT_TEST_
+environment set.
+
+GIT_TEST_SPLIT_INDEX=<boolean> forces split-index mode on the whole
+test suite. Accept any boolean values that are accepted by git-config.
+
+GIT_TEST_FULL_IN_PACK_ARRAY=<boolean> exercises the uncommon
+pack-objects code path where there are more than 1024 packs even if
+the actual number of packs in repository is below this limit. Accept
+any boolean values that are accepted by git-config.
+
+GIT_TEST_OE_SIZE=<n> exercises the uncommon pack-objects code path
+where we do not cache object size in memory and read it from existing
+packs on demand. This normally only happens when the object size is
+over 2GB. This variable forces the code path on any object larger than
+<n> bytes.

+# SECTION 4: Partially renamed directory; still exists on both sides of merge
+#
+# What if we were to attempt to do directory rename detection when someone
+# "mostly" moved a directory but still left some files around, or,
+# equivalently, fully renamed a directory in one commmit and then recreated
+# that directory in a later commit adding some new files and then tried to
+# merge?
+#
+# It's hard to divine user intent in these cases, because you can make an
+# argument that, depending on the intermediate history of the side being
+# merged, that some users will want files in that directory to
+# automatically be detected and renamed, while users with a different
+# intermediate history wouldn't want that rename to happen.
+#
+# I think that it is best to simply not have directory rename detection
+# apply to such cases. My reasoning for this is four-fold: (1) it's
+# easiest for users in general to figure out what happened if we don't
+# apply directory rename detection in any such case, (2) it's an easy rule
+# to explain ["We don't do directory rename detection if the directory
+# still exists on both sides of the merge"], (3) we can get some hairy
+# edge/corner cases that would be really confusing and possibly not even
+# representable in the index if we were to even try, and [related to 3] (4)
+# attempting to resolve this issue of divining user intent by examining
+# intermediate history goes against the spirit of three-way merges and is a
+# path towards crazy corner cases that are far more complex than what we're
+# already dealing with.
+#
+# Note that the wording of the rule ("We don't do directory rename
+# detection if the directory still exists on both sides of the merge.")
+# also excludes "renaming" of a directory into a subdirectory of itself
+# (e.g. /some/dir/* -> /some/dir/subdir/*). It may be possible to carve
+# out an exception for "renaming"-beneath-itself cases without opening
+# weird edge/corner cases for other partial directory renames, but for now
+# we are keeping the rule simple.
