+Git v2.14.3 Release Notes
+=========================
+
+Fixes since v2.14.2
+-------------------
+
+ * A helper function to read a single whole line into strbuf
+ mistakenly triggered OOM error at EOF under certain conditions,
+ which has been fixed.
+
+ * In addition to "cc: <a@dd.re.ss> # cruft", "cc: a@dd.re.ss # cruft"
+ was taught to "git send-email" as a valid way to tell it that it
+ needs to also send a carbon copy to <a@dd.re.ss> in the trailer
+ section.
+
+ * Fix regression to "gitk --bisect" by a recent update.
+
+ * Unlike "git commit-tree < file", "git commit-tree -F file" did not
+ pass the contents of the file verbatim and instead completed an
+ incomplete line at the end, if exists. The latter has been updated
+ to match the behaviour of the former.
+
+ * "git archive", especially when used with pathspec, stored an empty
+ directory in its output, even though Git itself never does so.
+ This has been fixed.
+
+ * API error-proofing which happens to also squelch warnings from GCC.
+
+ * "git gc" tries to avoid running two instances at the same time by
+ reading and writing pid/host from and to a lock file; it used to
+ use an incorrect fscanf() format when reading, which has been
+ corrected.
+
+ * The test linter has been taught that we do not like "echo -e".
+
+ * Code cmp.std.c nitpick.
+
+ * "git describe --match" learned to take multiple patterns in v2.13
+ series, but the feature ignored the patterns after the first one
+ and did not work at all. This has been fixed.
+
+ * "git cat-file --textconv" started segfaulting recently, which
+ has been corrected.
+
+ * The built-in pattern to detect the "function header" for HTML did
+ not match <H1>..<H6> elements without any attributes, which has
+ been fixed.
+
+ * "git mailinfo" was loose in decoding quoted printable and produced
+ garbage when the two letters after the equal sign are not
+ hexadecimal. This has been fixed.
+
+ * The documentation for '-X<option>' for merges was misleadingly
+ written to suggest that "-s theirs" exists, which is not the case.
+
+ * Spell the name of our system as "Git" in the output from
+ request-pull script.
+
+ * Fixes for a handful memory access issues identified by valgrind.
+
+ * Backports a moral equivalent of 2015 fix to the poll emulation from
+ the upstream gnulib to fix occasional breakages on HPE NonStop.
+
+ * In the "--format=..." option of the "git for-each-ref" command (and
+ its friends, i.e. the listing mode of "git branch/tag"), "%(atom:)"
+ (e.g. "%(refname:)", "%(body:)" used to error out. Instead, treat
+ them as if the colon and an empty string that follows it were not
+ there.
+
+ * Users with "color.ui = always" in their configuration were broken
+ by a recent change that made plumbing commands to pay attention to
+ them as the patch created internally by "git add -p" were colored
+ (heh) and made unusable. This has been fixed.
+
+Also contains various documentation updates and code clean-ups.

+Git 2.15 Release Notes
+======================
+
+Backward compatibility notes and other notable changes.
+
+ * Use of an empty string as a pathspec element that is used for
+ 'everything matches' is still warned and Git asks users to use a
+ more explicit '.' for that instead. The hope is that existing
+ users will not mind this change, and eventually the warning can be
+ turned into a hard error, upgrading the deprecation into removal of
+ this (mis)feature. That is now scheduled to happen in Git v2.16,
+ the next major release after this one.
+
+ * Git now avoids blindly falling back to ".git" when the setup
+ sequence said we are _not_ in Git repository. A corner case that
+ happens to work right now may be broken by a call to BUG().
+ We've tried hard to locate such cases and fixed them, but there
+ might still be cases that need to be addressed--bug reports are
+ greatly appreciated.
+
+ * "branch --set-upstream" that has been deprecated in Git 1.8 has
+ finally been retired.
+
+
+Updates since v2.14
+-------------------
+
+UI, Workflows & Features
+
+ * An example that is now obsolete has been removed from a sample hook,
+ and an old example in it that added a sign-off manually has been
+ improved to use the interpret-trailers command.
+
+ * The advice message given when "git rebase" stops for conflicting
+ changes has been improved.
+
+ * The "rerere-train" script (in contrib/) learned the "--overwrite"
+ option to allow overwriting existing recorded resolutions.
+
+ * "git contacts" (in contrib/) now lists the address on the
+ "Reported-by:" trailer to its output, in addition to those on
+ S-o-b: and other trailers, to make it easier to notify (and thank)
+ the original bug reporter.
+
+ * "git rebase", especially when it is run by mistake and ends up
+ trying to replay many changes, spent long time in silence. The
+ command has been taught to show progress report when it spends
+ long time preparing these many changes to replay (which would give
+ the user a chance to abort with ^C).
+
+ * "git merge" learned a "--signoff" option to add the Signed-off-by:
+ trailer with the committer's name.
+
+ * "git diff" learned to optionally paint new lines that are the same
+ as deleted lines elsewhere differently from genuinely new lines.
+
+ * "git interpret-trailers" learned to take the trailer specifications
+ from the command line that overrides the configured values.
+
+ * "git interpret-trailers" has been taught a "--parse" and a few
+ other options to make it easier for scripts to grab existing
+ trailer lines from a commit log message.
+
+ * The "--format=%(trailers)" option "git log" and its friends take
+ learned to take the 'unfold' and 'only' modifiers to normalize its
+ output, e.g. "git log --format=%(trailers:only,unfold)".
+
+ * "gitweb" shows a link to visit the 'raw' contents of blbos in the
+ history overview page.
+
+ * "[gc] rerereResolved = 5.days" used to be invalid, as the variable
+ is defined to take an integer counting the number of days. It now
+ is allowed.
+
+ * The code to acquire a lock on a reference (e.g. while accepting a
+ push from a client) used to immediately fail when the reference is
+ already locked---now it waits for a very short while and retries,
+ which can make it succeed if the lock holder was holding it during
+ a read-only operation.
+
+ * "branch --set-upstream" that has been deprecated in Git 1.8 has
+ finally been retired.
+
+ * The codepath to call external process filter for smudge/clean
+ operation learned to show the progress meter.
+
+ * "git rev-parse" learned "--is-shallow-repository", that is to be
+ used in a way similar to existing "--is-bare-repository" and
+ friends.
+
+ * "git describe --match <pattern>" has been taught to play well with
+ the "--all" option.
+
+ * "git branch" learned "-c/-C" to create a new branch by copying an
+ existing one.
+
+ * Some commands (most notably "git status") makes an opportunistic
+ update when performing a read-only operation to help optimize later
+ operations in the same repository. The new "--no-optional-locks"
+ option can be passed to Git to disable them.
+
+ * "git for-each-ref --format=..." learned a new format element,
+ %(trailers), to show only the commit log trailer part of the log
+ message.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * Start using selected c99 constructs in small, stable and
+ essentialpart of the system to catch people who care about
+ older compilers that do not grok them.
+
+ * The filter-process interface learned to allow a process with long
+ latency give a "delayed" response.
+
+ * Many uses of comparision callback function the hashmap API uses
+ cast the callback function type when registering it to
+ hashmap_init(), which defeats the compile time type checking when
+ the callback interface changes (e.g. gaining more parameters).
+ The callback implementations have been updated to take "void *"
+ pointers and cast them to the type they expect instead.
+
+ * Because recent Git for Windows do come with a real msgfmt, the
+ build procedure for git-gui has been updated to use it instead of a
+ hand-rolled substitute.
+
+ * "git grep --recurse-submodules" has been reworked to give a more
+ consistent output across submodule boundary (and do its thing
+ without having to fork a separate process).
+
+ * A helper function to read a single whole line into strbuf
+ mistakenly triggered OOM error at EOF under certain conditions,
+ which has been fixed.
+
+ * The "ref-store" code reorganization continues.
+
+ * "git commit" used to discard the index and re-read from the filesystem
+ just in case the pre-commit hook has updated it in the middle; this
+ has been optimized out when we know we do not run the pre-commit hook.
+ (merge 680ee550d7 kw/commit-keep-index-when-pre-commit-is-not-run later to maint).
+
+ * Updates to the HTTP layer we made recently unconditionally used
+ features of libCurl without checking the existence of them, causing
+ compilation errors, which has been fixed. Also migrate the code to
+ check feature macros, not version numbers, to cope better with
+ libCurl that vendor ships with backported features.
+
+ * The API to start showing progress meter after a short delay has
+ been simplified.
+ (merge 8aade107dd jc/simplify-progress later to maint).
+
+ * Code clean-up to avoid mixing values read from the .gitmodules file
+ and values read from the .git/config file.
+
+ * We used to spend more than necessary cycles allocating and freeing
+ piece of memory while writing each index entry out. This has been
+ optimized.
+
+ * Platforms that ship with a separate sha1 with collision detection
+ library can link to it instead of using the copy we ship as part of
+ our source tree.
+
+ * Code around "notes" have been cleaned up.
+ (merge 3964281524 mh/notes-cleanup later to maint).
+
+ * The long-standing rule that an in-core lockfile instance, once it
+ is used, must not be freed, has been lifted and the lockfile and
+ tempfile APIs have been updated to reduce the chance of programming
+ errors.
+
+ * Our hashmap implementation in hashmap.[ch] is not thread-safe when
+ adding a new item needs to expand the hashtable by rehashing; add
+ an API to disable the automatic rehashing to work it around.
+
+ * Many of our programs consider that it is OK to release dynamic
+ storage that is used throughout the life of the program by simply
+ exiting, but this makes it harder to leak detection tools to avoid
+ reporting false positives. Plug many existing leaks and introduce
+ a mechanism for developers to mark that the region of memory
+ pointed by a pointer is not lost/leaking to help these tools.
+
+ * As "git commit" to conclude a conflicted "git merge" honors the
+ commit-msg hook, "git merge" that records a merge commit that
+ cleanly auto-merges should, but it didn't.
+
+ * The codepath for "git merge-recursive" has been cleaned up.
+
+ * Many leaks of strbuf have been fixed.
+
+ * "git imap-send" has our own implementation of the protocol and also
+ can use more recent libCurl with the imap protocol support. Update
+ the latter so that it can use the credential subsystem, and then
+ make it the default option to use, so that we can eventually
+ deprecate and remove the former.
+
+ * "make style" runs git-clang-format to help developers by pointing
+ out coding style issues.
+
+ * A test to demonstrate "git mv" failing to adjust nested submodules
+ has been added.
+ (merge c514167df2 hv/mv-nested-submodules-test later to maint).
+
+ * On Cygwin, "ulimit -s" does not report failure but it does not work
+ at all, which causes an unexpected success of some tests that
+ expect failures under a limited stack situation. This has been
+ fixed.
+
+ * Many codepaths have been updated to squelch -Wimplicit-fallthrough
+ warnings from Gcc 7 (which is a good code hygiene).
+
+ * Add a helper for DLL loading in anticipation for its need in a
+ future topic RSN.
+
+ * "git status --ignored", when noticing that a directory without any
+ tracked path is ignored, still enumerated all the ignored paths in
+ the directory, which is unnecessary. The codepath has been
+ optimized to avoid this overhead.
+
+ * The final batch to "git rebase -i" updates to move more code from
+ the shell script to C has been merged.
+
+ * Operations that do not touch (majority of) packed refs have been
+ optimized by making accesses to packed-refs file lazy; we no longer
+ pre-parse everything, and an access to a single ref in the
+ packed-refs does not touch majority of irrelevant refs, either.
+
+ * Add comment to clarify that the style file is meant to be used with
+ clang-5 and the rules are still work in progress.
+
+ * Many variables that points at a region of memory that will live
+ throughout the life of the program have been marked with UNLEAK
+ marker to help the leak checkers concentrate on real leaks..
+
+ * Plans for weaning us off of SHA-1 has been documented.
+
+ * A new "oidmap" API has been introduced and oidset API has been
+ rewritten to use it.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.14
+-----------------
+
+ * "%C(color name)" in the pretty print format always produced ANSI
+ color escape codes, which was an early design mistake. They now
+ honor the configuration (e.g. "color.ui = never") and also tty-ness
+ of the output medium.
+
+ * The http.{sslkey,sslCert} configuration variables are to be
+ interpreted as a pathname that honors "~[username]/" prefix, but
+ weren't, which has been fixed.
+
+ * Numerous bugs in walking of reflogs via "log -g" and friends have
+ been fixed.
+
+ * "git commit" when seeing an totally empty message said "you did not
+ edit the message", which is clearly wrong. The message has been
+ corrected.
+
+ * When a directory is not readable, "gitweb" fails to build the
+ project list. Work this around by skipping such a directory.
+
+ * Some versions of GnuPG fails to kill gpg-agent it auto-spawned
+ and such a left-over agent can interfere with a test. Work it
+ around by attempting to kill one before starting a new test.
+
+ * A recently added test for the "credential-cache" helper revealed
+ that EOF detection done around the time the connection to the cache
+ daemon is torn down were flaky. This was fixed by reacting to
+ ECONNRESET and behaving as if we got an EOF.
+
+ * "git log --tag=no-such-tag" showed log starting from HEAD, which
+ has been fixed---it now shows nothing.
+
+ * The "tag.pager" configuration variable was useless for those who
+ actually create tag objects, as it interfered with the use of an
+ editor. A new mechanism has been introduced for commands to enable
+ pager depending on what operation is being carried out to fix this,
+ and then "git tag -l" is made to run pager by default.
+
+ * "git push --recurse-submodules $there HEAD:$target" was not
+ propagated down to the submodules, but now it is.
+
+ * Commands like "git rebase" accepted the --rerere-autoupdate option
+ from the command line, but did not always use it. This has been
+ fixed.
+
+ * "git clone --recurse-submodules --quiet" did not pass the quiet
+ option down to submodules.
+
+ * Test portability fix for OBSD.
+
+ * Portability fix for OBSD.
+
+ * "git am -s" has been taught that some input may end with a trailer
+ block that is not Signed-off-by: and it should refrain from adding
+ an extra blank line before adding a new sign-off in such a case.
+
+ * "git svn" used with "--localtime" option did not compute the tz
+ offset for the timestamp in question and instead always used the
+ current time, which has been corrected.
+
+ * Memory leak in an error codepath has been plugged.
+
+ * "git stash -u" used the contents of the committed version of the
+ ".gitignore" file to decide which paths are ignored, even when the
+ file has local changes. The command has been taught to instead use
+ the locally modified contents.
+
+ * bash 4.4 or newer gave a warning on NUL byte in command
+ substitution done in "git stash"; this has been squelched.
+
+ * "git grep -L" and "git grep --quiet -L" reported different exit
+ codes; this has been corrected.
+
+ * When handshake with a subprocess filter notices that the process
+ asked for an unknown capability, Git did not report what program
+ the offending subprocess was running. This has been corrected.
+
+ * "git apply" that is used as a better "patch -p1" failed to apply a
+ taken from a file with CRLF line endings to a file with CRLF line
+ endings. The root cause was because it misused convert_to_git()
+ that tried to do "safe-crlf" processing by looking at the index
+ entry at the same path, which is a nonsense---in that mode, "apply"
+ is not working on the data in (or derived from) the index at all.
+ This has been fixed.
+
+ * Killing "git merge --edit" before the editor returns control left
+ the repository in a state with MERGE_MSG but without MERGE_HEAD,
+ which incorrectly tells the subsequent "git commit" that there was
+ a squash merge in progress. This has been fixed.
+
+ * "git archive" did not work well with pathspecs and the
+ export-ignore attribute.
+
+ * In addition to "cc: <a@dd.re.ss> # cruft", "cc: a@dd.re.ss # cruft"
+ was taught to "git send-email" as a valid way to tell it that it
+ needs to also send a carbon copy to <a@dd.re.ss> in the trailer
+ section.
+
+ * "git branch -M a b" while on a branch that is completely unrelated

-string-list API
-===============
-
-The string_list API offers a data structure and functions to handle
-sorted and unsorted string lists. A "sorted" list is one whose
-entries are sorted by string value in `strcmp()` order.
-
-The 'string_list' struct used to be called 'path_list', but was renamed
-because it is not specific to paths.
-
-The caller:
-
-. Allocates and clears a `struct string_list` variable.
-
-. Initializes the members. You might want to set the flag `strdup_strings`
- if the strings should be strdup()ed. For example, this is necessary
- when you add something like git_path("..."), since that function returns
- a static buffer that will change with the next call to git_path().
-+
-If you need something advanced, you can manually malloc() the `items`
-member (you need this if you add things later) and you should set the
-`nr` and `alloc` members in that case, too.
-
-. Adds new items to the list, using `string_list_append`,
- `string_list_append_nodup`, `string_list_insert`,
- `string_list_split`, and/or `string_list_split_in_place`.
-
-. Can check if a string is in the list using `string_list_has_string` or
- `unsorted_string_list_has_string` and get it from the list using
- `string_list_lookup` for sorted lists.
-
-. Can sort an unsorted list using `string_list_sort`.
-
-. Can remove duplicate items from a sorted list using
- `string_list_remove_duplicates`.
-
-. Can remove individual items of an unsorted list using
- `unsorted_string_list_delete_item`.
-
-. Can remove items not matching a criterion from a sorted or unsorted
- list using `filter_string_list`, or remove empty strings using
- `string_list_remove_empty_items`.
-
-. Finally it should free the list using `string_list_clear`.
-
-Example:
-
-----
-struct string_list list = STRING_LIST_INIT_NODUP;
-int i;
-
-string_list_append(&list, "foo");
-string_list_append(&list, "bar");
-for (i = 0; i < list.nr; i++)
- printf("%s\n", list.items[i].string)
-----
-
-NOTE: It is more efficient to build an unsorted list and sort it
-afterwards, instead of building a sorted list (`O(n log n)` instead of
-`O(n^2)`).
-+
-However, if you use the list to check if a certain string was added
-already, you should not do that (using unsorted_string_list_has_string()),
-because the complexity would be quadratic again (but with a worse factor).
-
-Functions
----------
-
-* General ones (works with sorted and unsorted lists as well)
-
-`string_list_init`::
-
- Initialize the members of the string_list, set `strdup_strings`
- member according to the value of the second parameter.
-
-`filter_string_list`::
-
- Apply a function to each item in a list, retaining only the
- items for which the function returns true. If free_util is
- true, call free() on the util members of any items that have
- to be deleted. Preserve the order of the items that are
- retained.
-
-`string_list_remove_empty_items`::
-
- Remove any empty strings from the list. If free_util is true,
- call free() on the util members of any items that have to be
- deleted. Preserve the order of the items that are retained.
-
-`print_string_list`::
-
- Dump a string_list to stdout, useful mainly for debugging purposes. It
- can take an optional header argument and it writes out the
- string-pointer pairs of the string_list, each one in its own line.
-
-`string_list_clear`::
-
- Free a string_list. The `string` pointer of the items will be freed in
- case the `strdup_strings` member of the string_list is set. The second
- parameter controls if the `util` pointer of the items should be freed
- or not.
-
-* Functions for sorted lists only
-
-`string_list_has_string`::
-
- Determine if the string_list has a given string or not.
-
-`string_list_insert`::
-
- Insert a new element to the string_list. The returned pointer can be
- handy if you want to write something to the `util` pointer of the
- string_list_item containing the just added string. If the given
- string already exists the insertion will be skipped and the
- pointer to the existing item returned.
-+
-Since this function uses xrealloc() (which die()s if it fails) if the
-list needs to grow, it is safe not to check the pointer. I.e. you may
-write `string_list_insert(...)->util = ...;`.
-
-`string_list_lookup`::
-
- Look up a given string in the string_list, returning the containing
- string_list_item. If the string is not found, NULL is returned.
-
-`string_list_remove_duplicates`::
-
- Remove all but the first of consecutive entries that have the
- same string value. If free_util is true, call free() on the
- util members of any items that have to be deleted.
-
-* Functions for unsorted lists only
-
-`string_list_append`::
-
- Append a new string to the end of the string_list. If
- `strdup_string` is set, then the string argument is copied;
- otherwise the new `string_list_entry` refers to the input
- string.
-
-`string_list_append_nodup`::
-
- Append a new string to the end of the string_list. The new
- `string_list_entry` always refers to the input string, even if
- `strdup_string` is set. This function can be used to hand
- ownership of a malloc()ed string to a `string_list` that has
- `strdup_string` set.
-
-`string_list_sort`::
-
- Sort the list's entries by string value in `strcmp()` order.
-
-`unsorted_string_list_has_string`::
-
- It's like `string_list_has_string()` but for unsorted lists.
-
-`unsorted_string_list_lookup`::
-
- It's like `string_list_lookup()` but for unsorted lists.
-+
-The above two functions need to look through all items, as opposed to their
-counterpart for sorted lists, which performs a binary search.
-
-`unsorted_string_list_delete_item`::
-
- Remove an item from a string_list. The `string` pointer of the items
- will be freed in case the `strdup_strings` member of the string_list
- is set. The third parameter controls if the `util` pointer of the
- items should be freed or not.
-
-`string_list_split`::
-`string_list_split_in_place`::
-
- Split a string into substrings on a delimiter character and
- append the substrings to a `string_list`. If `maxsplit` is
- non-negative, then split at most `maxsplit` times. Return the
- number of substrings appended to the list.
-+
-`string_list_split` requires a `string_list` that has `strdup_strings`
-set to true; it leaves the input string untouched and makes copies of
-the substrings in newly-allocated memory.
-`string_list_split_in_place` requires a `string_list` that has
-`strdup_strings` set to false; it splits the input string in place,
-overwriting the delimiter characters with NULs and creating new
-string_list_items that point into the original string (the original
-string must therefore not be modified or freed while the `string_list`
-is in use).
-
-
-Data structures
----------------
-
-* `struct string_list_item`
-
-Represents an item of the list. The `string` member is a pointer to the
-string, and you may use the `util` member for any purpose, if you want.
-
-* `struct string_list`
-
-Represents the list itself.
-
-. The array of items are available via the `items` member.
-. The `nr` member contains the number of items stored in the list.
-. The `alloc` member is used to avoid reallocating at every insertion.
- You should not tamper with it.
-. Setting the `strdup_strings` member to 1 will strdup() the strings
- before adding them, see above.
-. The `compare_strings_fn` member is used to specify a custom compare
- function, otherwise `strcmp()` is used as the default function.

+Git hash function transition
+============================
+
+Objective
+---------
+Migrate Git from SHA-1 to a stronger hash function.
+
+Background
+----------
+At its core, the Git version control system is a content addressable
+filesystem. It uses the SHA-1 hash function to name content. For
+example, files, directories, and revisions are referred to by hash
+values unlike in other traditional version control systems where files
+or versions are referred to via sequential numbers. The use of a hash
+function to address its content delivers a few advantages:
+
+* Integrity checking is easy. Bit flips, for example, are easily
+ detected, as the hash of corrupted content does not match its name.
+* Lookup of objects is fast.
+
+Using a cryptographically secure hash function brings additional
+advantages:
+
+* Object names can be signed and third parties can trust the hash to
+ address the signed object and all objects it references.
+* Communication using Git protocol and out of band communication
+ methods have a short reliable string that can be used to reliably
+ address stored content.
+
+Over time some flaws in SHA-1 have been discovered by security
+researchers. https://shattered.io demonstrated a practical SHA-1 hash
+collision. As a result, SHA-1 cannot be considered cryptographically
+secure any more. This impacts the communication of hash values because
+we cannot trust that a given hash value represents the known good
+version of content that the speaker intended.
+
+SHA-1 still possesses the other properties such as fast object lookup
+and safe error checking, but other hash functions are equally suitable
+that are believed to be cryptographically secure.
+
+Goals
+-----
+Where NewHash is a strong 256-bit hash function to replace SHA-1 (see
+"Selection of a New Hash", below):
+
+1. The transition to NewHash can be done one local repository at a time.
+ a. Requiring no action by any other party.
+ b. A NewHash repository can communicate with SHA-1 Git servers
+ (push/fetch).
+ c. Users can use SHA-1 and NewHash identifiers for objects
+ interchangeably (see "Object names on the command line", below).
+ d. New signed objects make use of a stronger hash function than
+ SHA-1 for their security guarantees.
+2. Allow a complete transition away from SHA-1.
+ a. Local metadata for SHA-1 compatibility can be removed from a
+ repository if compatibility with SHA-1 is no longer needed.
+3. Maintainability throughout the process.
+ a. The object format is kept simple and consistent.
+ b. Creation of a generalized repository conversion tool.
+
+Non-Goals
+---------
+1. Add NewHash support to Git protocol. This is valuable and the
+ logical next step but it is out of scope for this initial design.
+2. Transparently improving the security of existing SHA-1 signed
+ objects.
+3. Intermixing objects using multiple hash functions in a single
+ repository.
+4. Taking the opportunity to fix other bugs in Git's formats and
+ protocols.
+5. Shallow clones and fetches into a NewHash repository. (This will
+ change when we add NewHash support to Git protocol.)
+6. Skip fetching some submodules of a project into a NewHash
+ repository. (This also depends on NewHash support in Git
+ protocol.)
+
+Overview
+--------
+We introduce a new repository format extension. Repositories with this
+extension enabled use NewHash instead of SHA-1 to name their objects.
+This affects both object names and object content --- both the names
+of objects and all references to other objects within an object are
+switched to the new hash function.
+
+NewHash repositories cannot be read by older versions of Git.
+
+Alongside the packfile, a NewHash repository stores a bidirectional
+mapping between NewHash and SHA-1 object names. The mapping is generated
+locally and can be verified using "git fsck". Object lookups use this
+mapping to allow naming objects using either their SHA-1 and NewHash names
+interchangeably.
+
+"git cat-file" and "git hash-object" gain options to display an object
+in its sha1 form and write an object given its sha1 form. This
+requires all objects referenced by that object to be present in the
+object database so that they can be named using the appropriate name
+(using the bidirectional hash mapping).
+
+Fetches from a SHA-1 based server convert the fetched objects into
+NewHash form and record the mapping in the bidirectional mapping table
+(see below for details). Pushes to a SHA-1 based server convert the
+objects being pushed into sha1 form so the server does not have to be
+aware of the hash function the client is using.
+
+Detailed Design
+---------------
+Repository format extension
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+A NewHash repository uses repository format version `1` (see
+Documentation/technical/repository-version.txt) with extensions
+`objectFormat` and `compatObjectFormat`:
+
+ [core]
+ repositoryFormatVersion = 1
+ [extensions]
+ objectFormat = newhash
+ compatObjectFormat = sha1
+
+Specifying a repository format extension ensures that versions of Git
+not aware of NewHash do not try to operate on these repositories,
+instead producing an error message:
+
+ $ git status
+ fatal: unknown repository extensions found:
+ objectformat
+ compatobjectformat
+
+See the "Transition plan" section below for more details on these
+repository extensions.
+
+Object names
+~~~~~~~~~~~~
+Objects can be named by their 40 hexadecimal digit sha1-name or 64
+hexadecimal digit newhash-name, plus names derived from those (see
+gitrevisions(7)).
+
+The sha1-name of an object is the SHA-1 of the concatenation of its
+type, length, a nul byte, and the object's sha1-content. This is the
+traditional <sha1> used in Git to name objects.
+
+The newhash-name of an object is the NewHash of the concatenation of its
+type, length, a nul byte, and the object's newhash-content.
+
+Object format
+~~~~~~~~~~~~~
+The content as a byte sequence of a tag, commit, or tree object named
+by sha1 and newhash differ because an object named by newhash-name refers to
+other objects by their newhash-names and an object named by sha1-name
+refers to other objects by their sha1-names.
+
+The newhash-content of an object is the same as its sha1-content, except
+that objects referenced by the object are named using their newhash-names
+instead of sha1-names. Because a blob object does not refer to any
+other object, its sha1-content and newhash-content are the same.
+
+The format allows round-trip conversion between newhash-content and
+sha1-content.
+
+Object storage
+~~~~~~~~~~~~~~
+Loose objects use zlib compression and packed objects use the packed
+format described in Documentation/technical/pack-format.txt, just like
+today. The content that is compressed and stored uses newhash-content
+instead of sha1-content.
+
+Pack index
+~~~~~~~~~~
+Pack index (.idx) files use a new v3 format that supports multiple
+hash functions. They have the following format (all integers are in
+network byte order):
+
+- A header appears at the beginning and consists of the following:
+ - The 4-byte pack index signature: '\377t0c'
+ - 4-byte version number: 3
+ - 4-byte length of the header section, including the signature and
+ version number
+ - 4-byte number of objects contained in the pack
+ - 4-byte number of object formats in this pack index: 2
+ - For each object format:
+ - 4-byte format identifier (e.g., 'sha1' for SHA-1)
+ - 4-byte length in bytes of shortened object names. This is the
+ shortest possible length needed to make names in the shortened
+ object name table unambiguous.
+ - 4-byte integer, recording where tables relating to this format
+ are stored in this index file, as an offset from the beginning.
+ - 4-byte offset to the trailer from the beginning of this file.
+ - Zero or more additional key/value pairs (4-byte key, 4-byte
+ value). Only one key is supported: 'PSRC'. See the "Loose objects
+ and unreachable objects" section for supported values and how this
+ is used. All other keys are reserved. Readers must ignore
+ unrecognized keys.
+- Zero or more NUL bytes. This can optionally be used to improve the
+ alignment of the full object name table below.
+- Tables for the first object format:
+ - A sorted table of shortened object names. These are prefixes of
+ the names of all objects in this pack file, packed together
+ without offset values to reduce the cache footprint of the binary
+ search for a specific object name.
+
+ - A table of full object names in pack order. This allows resolving
+ a reference to "the nth object in the pack file" (from a
+ reachability bitmap or from the next table of another object
+ format) to its object name.
+
+ - A table of 4-byte values mapping object name order to pack order.
+ For an object in the table of sorted shortened object names, the
+ value at the corresponding index in this table is the index in the
+ previous table for that same object.
+
+ This can be used to look up the object in reachability bitmaps or
+ to look up its name in another object format.
+
+ - A table of 4-byte CRC32 values of the packed object data, in the
+ order that the objects appear in the pack file. This is to allow
+ compressed data to be copied directly from pack to pack during
+ repacking without undetected data corruption.
+
+ - A table of 4-byte offset values. For an object in the table of
+ sorted shortened object names, the value at the corresponding
+ index in this table indicates where that object can be found in
+ the pack file. These are usually 31-bit pack file offsets, but
+ large offsets are encoded as an index into the next table with the
+ most significant bit set.
+
+ - A table of 8-byte offset entries (empty for pack files less than
+ 2 GiB). Pack files are organized with heavily used objects toward
+ the front, so most object references should not need to refer to
+ this table.
+- Zero or more NUL bytes.
+- Tables for the second object format, with the same layout as above,
+ up to and not including the table of CRC32 values.
+- Zero or more NUL bytes.
+- The trailer consists of the following:
+ - A copy of the 20-byte NewHash checksum at the end of the
+ corresponding packfile.
+
+ - 20-byte NewHash checksum of all of the above.
+
+Loose object index
+~~~~~~~~~~~~~~~~~~
+A new file $GIT_OBJECT_DIR/loose-object-idx contains information about
+all loose objects. Its format is
+
+ # loose-object-idx
+ (newhash-name SP sha1-name LF)*
+
+where the object names are in hexadecimal format. The file is not
+sorted.
+
+The loose object index is protected against concurrent writes by a
+lock file $GIT_OBJECT_DIR/loose-object-idx.lock. To add a new loose
+object:
+
+1. Write the loose object to a temporary file, like today.
+2. Open loose-object-idx.lock with O_CREAT | O_EXCL to acquire the lock.
+3. Rename the loose object into place.
+4. Open loose-object-idx with O_APPEND and write the new object
+5. Unlink loose-object-idx.lock to release the lock.
+
+To remove entries (e.g. in "git pack-refs" or "git-prune"):
+
+1. Open loose-object-idx.lock with O_CREAT | O_EXCL to acquire the
+ lock.
+2. Write the new content to loose-object-idx.lock.
+3. Unlink any loose objects being removed.
+4. Rename to replace loose-object-idx, releasing the lock.
+
+Translation table
+~~~~~~~~~~~~~~~~~
+The index files support a bidirectional mapping between sha1-names
+and newhash-names. The lookup proceeds similarly to ordinary object
+lookups. For example, to convert a sha1-name to a newhash-name:
+
+ 1. Look for the object in idx files. If a match is present in the
+ idx's sorted list of truncated sha1-names, then:
+ a. Read the corresponding entry in the sha1-name order to pack
+ name order mapping.
+ b. Read the corresponding entry in the full sha1-name table to
+ verify we found the right object. If it is, then
+ c. Read the corresponding entry in the full newhash-name table.
+ That is the object's newhash-name.
+ 2. Check for a loose object. Read lines from loose-object-idx until
+ we find a match.
+
+Step (1) takes the same amount of time as an ordinary object lookup:
+O(number of packs * log(objects per pack)). Step (2) takes O(number of
+loose objects) time. To maintain good performance it will be necessary
+to keep the number of loose objects low. See the "Loose objects and
+unreachable objects" section below for more details.
+
+Since all operations that make new objects (e.g., "git commit") add
+the new objects to the corresponding index, this mapping is possible
+for all objects in the object store.
+
+Reading an object's sha1-content
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The sha1-content of an object can be read by converting all newhash-names
+its newhash-content references to sha1-names using the translation table.
+
+Fetch
+~~~~~
+Fetching from a SHA-1 based server requires translating between SHA-1
+and NewHash based representations on the fly.
+
+SHA-1s named in the ref advertisement that are present on the client
+can be translated to NewHash and looked up as local objects using the
+translation table.
+
+Negotiation proceeds as today. Any "have"s generated locally are
+converted to SHA-1 before being sent to the server, and SHA-1s
+mentioned by the server are converted to NewHash when looking them up
+locally.
+
+After negotiation, the server sends a packfile containing the
+requested objects. We convert the packfile to NewHash format using
+the following steps:
+
+1. index-pack: inflate each object in the packfile and compute its
+ SHA-1. Objects can contain deltas in OBJ_REF_DELTA format against
+ objects the client has locally. These objects can be looked up
+ using the translation table and their sha1-content read as
+ described above to resolve the deltas.
+2. topological sort: starting at the "want"s from the negotiation
+ phase, walk through objects in the pack and emit a list of them,
+ excluding blobs, in reverse topologically sorted order, with each
+ object coming later in the list than all objects it references.
+ (This list only contains objects reachable from the "wants". If the
+ pack from the server contained additional extraneous objects, then
+ they will be discarded.)
+3. convert to newhash: open a new (newhash) packfile. Read the topologically
+ sorted list just generated. For each object, inflate its
+ sha1-content, convert to newhash-content, and write it to the newhash
+ pack. Record the new sha1<->newhash mapping entry for use in the idx.
+4. sort: reorder entries in the new pack to match the order of objects
+ in the pack the server generated and include blobs. Write a newhash idx
+ file
+5. clean up: remove the SHA-1 based pack file, index, and
+ topologically sorted list obtained from the server in steps 1
+ and 2.
+
+Step 3 requires every object referenced by the new object to be in the
+translation table. This is why the topological sort step is necessary.
+
+As an optimization, step 1 could write a file describing what non-blob
+objects each object it has inflated from the packfile references. This
+makes the topological sort in step 2 possible without inflating the
+objects in the packfile for a second time. The objects need to be
+inflated again in step 3, for a total of two inflations.
+
+Step 4 is probably necessary for good read-time performance. "git
+pack-objects" on the server optimizes the pack file for good data
+locality (see Documentation/technical/pack-heuristics.txt).
+
+Details of this process are likely to change. It will take some
+experimenting to get this to perform well.
+
+Push
+~~~~
+Push is simpler than fetch because the objects referenced by the
+pushed objects are already in the translation table. The sha1-content
+of each object being pushed can be read as described in the "Reading
+an object's sha1-content" section to generate the pack written by git
+send-pack.
+
+Signed Commits
+~~~~~~~~~~~~~~
+We add a new field "gpgsig-newhash" to the commit object format to allow
+signing commits without relying on SHA-1. It is similar to the
+existing "gpgsig" field. Its signed payload is the newhash-content of the
+commit object with any "gpgsig" and "gpgsig-newhash" fields removed.
+
+This means commits can be signed
+1. using SHA-1 only, as in existing signed commit objects
+2. using both SHA-1 and NewHash, by using both gpgsig-newhash and gpgsig
+ fields.
+3. using only NewHash, by only using the gpgsig-newhash field.
+
+Old versions of "git verify-commit" can verify the gpgsig signature in
+cases (1) and (2) without modifications and view case (3) as an
+ordinary unsigned commit.
+
+Signed Tags
+~~~~~~~~~~~
+We add a new field "gpgsig-newhash" to the tag object format to allow
+signing tags without relying on SHA-1. Its signed payload is the
+newhash-content of the tag with its gpgsig-newhash field and "-----BEGIN PGP
+SIGNATURE-----" delimited in-body signature removed.
+
+This means tags can be signed
+1. using SHA-1 only, as in existing signed tag objects
+2. using both SHA-1 and NewHash, by using gpgsig-newhash and an in-body
+ signature.
+3. using only NewHash, by only using the gpgsig-newhash field.
+
+Mergetag embedding
+~~~~~~~~~~~~~~~~~~
+The mergetag field in the sha1-content of a commit contains the
+sha1-content of a tag that was merged by that commit.
+
+The mergetag field in the newhash-content of the same commit contains the
+newhash-content of the same tag.
+
+Submodules
+~~~~~~~~~~
+To convert recorded submodule pointers, you need to have the converted
+submodule repository in place. The translation table of the submodule
+can be used to look up the new hash.
+
+Loose objects and unreachable objects
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Fast lookups in the loose-object-idx require that the number of loose
+objects not grow too high.
+
+"git gc --auto" currently waits for there to be 6700 loose objects
+present before consolidating them into a packfile. We will need to
+measure to find a more appropriate threshold for it to use.
+
+"git gc --auto" currently waits for there to be 50 packs present
+before combining packfiles. Packing loose objects more aggressively
+may cause the number of pack files to grow too quickly. This can be
+mitigated by using a strategy similar to Martin Fick's exponential
+rolling garbage collection script:
+https://gerrit-review.googlesource.com/c/gerrit/+/35215
+
+"git gc" currently expels any unreachable objects it encounters in
+pack files to loose objects in an attempt to prevent a race when
+pruning them (in case another process is simultaneously writing a new
+object that refers to the about-to-be-deleted object). This leads to
+an explosion in the number of loose objects present and disk space
+usage due to the objects in delta form being replaced with independent
+loose objects. Worse, the race is still present for loose objects.
+
+Instead, "git gc" will need to move unreachable objects to a new
+packfile marked as UNREACHABLE_GARBAGE (using the PSRC field; see
+below). To avoid the race when writing new objects referring to an
+about-to-be-deleted object, code paths that write new objects will
+need to copy any objects from UNREACHABLE_GARBAGE packs that they
+refer to to new, non-UNREACHABLE_GARBAGE packs (or loose objects).
+UNREACHABLE_GARBAGE are then safe to delete if their creation time (as
+indicated by the file's mtime) is long enough ago.
+
+To avoid a proliferation of UNREACHABLE_GARBAGE packs, they can be
+combined under certain circumstances. If "gc.garbageTtl" is set to
+greater than one day, then packs created within a single calendar day,
+UTC, can be coalesced together. The resulting packfile would have an
+mtime before midnight on that day, so this makes the effective maximum
+ttl the garbageTtl + 1 day. If "gc.garbageTtl" is less than one day,
+then we divide the calendar day into intervals one-third of that ttl
+in duration. Packs created within the same interval can be coalesced
+together. The resulting packfile would have an mtime before the end of
+the interval, so this makes the effective maximum ttl equal to the
+garbageTtl * 4/3.
+
+This rule comes from Thirumala Reddy Mutchukota's JGit change
+https://git.eclipse.org/r/90465.
+
+The UNREACHABLE_GARBAGE setting goes in the PSRC field of the pack
+index. More generally, that field indicates where a pack came from:
+
+ - 1 (PACK_SOURCE_RECEIVE) for a pack received over the network
+ - 2 (PACK_SOURCE_AUTO) for a pack created by a lightweight
+ "gc --auto" operation
+ - 3 (PACK_SOURCE_GC) for a pack created by a full gc
+ - 4 (PACK_SOURCE_UNREACHABLE_GARBAGE) for potential garbage
+ discovered by gc
+ - 5 (PACK_SOURCE_INSERT) for locally created objects that were
+ written directly to a pack file, e.g. from "git add ."
+
+This information can be useful for debugging and for "gc --auto" to
+make appropriate choices about which packs to coalesce.
+
+Caveats
+-------
+Invalid objects
+~~~~~~~~~~~~~~~
+The conversion from sha1-content to newhash-content retains any
+brokenness in the original object (e.g., tree entry modes encoded with
+leading 0, tree objects whose paths are not sorted correctly, and
+commit objects without an author or committer). This is a deliberate
+feature of the design to allow the conversion to round-trip.
+
+More profoundly broken objects (e.g., a commit with a truncated "tree"
+header line) cannot be converted but were not usable by current Git
+anyway.
+
+Shallow clone and submodules
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Because it requires all referenced objects to be available in the
+locally generated translation table, this design does not support
+shallow clone or unfetched submodules. Protocol improvements might
+allow lifting this restriction.
+
+Alternates
+~~~~~~~~~~
+For the same reason, a newhash repository cannot borrow objects from a
+sha1 repository using objects/info/alternates or
+$GIT_ALTERNATE_OBJECT_REPOSITORIES.
+
+git notes
+~~~~~~~~~
+The "git notes" tool annotates objects using their sha1-name as key.
+This design does not describe a way to migrate notes trees to use
+newhash-names. That migration is expected to happen separately (for
+example using a file at the root of the notes tree to describe which
+hash it uses).
+
+Server-side cost
+~~~~~~~~~~~~~~~~
+Until Git protocol gains NewHash support, using NewHash based storage
+on public-facing Git servers is strongly discouraged. Once Git
+protocol gains NewHash support, NewHash based servers are likely not
+to support SHA-1 compatibility, to avoid what may be a very expensive
+hash reencode during clone and to encourage peers to modernize.
+
+The design described here allows fetches by SHA-1 clients of a
+personal NewHash repository because it's not much more difficult than
+allowing pushes from that repository. This support needs to be guarded
+by a configuration option --- servers like git.kernel.org that serve a
+large number of clients would not be expected to bear that cost.
+
+Meaning of signatures
+~~~~~~~~~~~~~~~~~~~~~
+The signed payload for signed commits and tags does not explicitly
+name the hash used to identify objects. If some day Git adopts a new
+hash function with the same length as the current SHA-1 (40
+hexadecimal digit) or NewHash (64 hexadecimal digit) objects then the
+intent behind the PGP signed payload in an object signature is
+unclear:
+
+ object e7e07d5a4fcc2a203d9873968ad3e6bd4d7419d7
+ type commit
+ tag v2.12.0
+ tagger Junio C Hamano <gitster@pobox.com> 1487962205 -0800
+
+ Git 2.12
+
+Does this mean Git v2.12.0 is the commit with sha1-name
+e7e07d5a4fcc2a203d9873968ad3e6bd4d7419d7 or the commit with
+new-40-digit-hash-name e7e07d5a4fcc2a203d9873968ad3e6bd4d7419d7?
+
+Fortunately NewHash and SHA-1 have different lengths. If Git starts
+using another hash with the same length to name objects, then it will
+need to change the format of signed payloads using that hash to
+address this issue.
+
+Object names on the command line
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+To support the transition (see Transition plan below), this design
+supports four different modes of operation:
+
+ 1. ("dark launch") Treat object names input by the user as SHA-1 and
+ convert any object names written to output to SHA-1, but store
+ objects using NewHash. This allows users to test the code with no
+ visible behavior change except for performance. This allows
+ allows running even tests that assume the SHA-1 hash function, to
+ sanity-check the behavior of the new mode.
+
+ 2. ("early transition") Allow both SHA-1 and NewHash object names in
+ input. Any object names written to output use SHA-1. This allows
+ users to continue to make use of SHA-1 to communicate with peers
+ (e.g. by email) that have not migrated yet and prepares for mode 3.
+
+ 3. ("late transition") Allow both SHA-1 and NewHash object names in
+ input. Any object names written to output use NewHash. In this
+ mode, users are using a more secure object naming method by
+ default. The disruption is minimal as long as most of their peers
+ are in mode 2 or mode 3.
+
+ 4. ("post-transition") Treat object names input by the user as
+ NewHash and write output using NewHash. This is safer than mode 3
+ because there is less risk that input is incorrectly interpreted
+ using the wrong hash function.
+
+The mode is specified in configuration.
+
+The user can also explicitly specify which format to use for a
+particular revision specifier and for output, overriding the mode. For
+example:
+
+git --output-format=sha1 log abac87a^{sha1}..f787cac^{newhash}
+
+Selection of a New Hash
+-----------------------
+In early 2005, around the time that Git was written, Xiaoyun Wang,
+Yiqun Lisa Yin, and Hongbo Yu announced an attack finding SHA-1
+collisions in 2^69 operations. In August they published details.
+Luckily, no practical demonstrations of a collision in full SHA-1 were
+published until 10 years later, in 2017.
+
+The hash function NewHash to replace SHA-1 should be stronger than
+SHA-1 was: we would like it to be trustworthy and useful in practice
+for at least 10 years.
+
+Some other relevant properties:
+
+1. A 256-bit hash (long enough to match common security practice; not
+ excessively long to hurt performance and disk usage).
+
+2. High quality implementations should be widely available (e.g. in
+ OpenSSL).
+
+3. The hash function's properties should match Git's needs (e.g. Git
+ requires collision and 2nd preimage resistance and does not require
+ length extension resistance).
+
+4. As a tiebreaker, the hash should be fast to compute (fortunately
+ many contenders are faster than SHA-1).
+
+Some hashes under consideration are SHA-256, SHA-512/256, SHA-256x16,
+K12, and BLAKE2bp-256.
+
+Transition plan
+---------------
+Some initial steps can be implemented independently of one another:
+- adding a hash function API (vtable)
+- teaching fsck to tolerate the gpgsig-newhash field
+- excluding gpgsig-* from the fields copied by "git commit --amend"
+- annotating tests that depend on SHA-1 values with a SHA1 test
+ prerequisite
+- using "struct object_id", GIT_MAX_RAWSZ, and GIT_MAX_HEXSZ
+ consistently instead of "unsigned char *" and the hardcoded
+ constants 20 and 40.
+- introducing index v3
+- adding support for the PSRC field and safer object pruning
+
+
+The first user-visible change is the introduction of the objectFormat
+extension (without compatObjectFormat). This requires:
+- implementing the loose-object-idx
+- teaching fsck about this mode of operation
+- using the hash function API (vtable) when computing object names
+- signing objects and verifying signatures
+- rejecting attempts to fetch from or push to an incompatible
+ repository
+
+Next comes introduction of compatObjectFormat:
+- translating object names between object formats
+- translating object content between object formats
+- generating and verifying signatures in the compat format
+- adding appropriate index entries when adding a new object to the
+ object store
+- --output-format option
+- ^{sha1} and ^{newhash} revision notation
+- configuration to specify default input and output format (see
+ "Object names on the command line" above)
+
+The next step is supporting fetches and pushes to SHA-1 repositories:
+- allow pushes to a repository using the compat format
+- generate a topologically sorted list of the SHA-1 names of fetched
+ objects
+- convert the fetched packfile to newhash format and generate an idx
+ file
+- re-sort to match the order of objects in the fetched packfile
+
+The infrastructure supporting fetch also allows converting an existing
+repository. In converted repositories and new clones, end users can
+gain support for the new hash function without any visible change in
+behavior (see "dark launch" in the "Object names on the command line"
+section). In particular this allows users to verify NewHash signatures
+on objects in the repository, and it should ensure the transition code
+is stable in production in preparation for using it more widely.
+
+Over time projects would encourage their users to adopt the "early
+transition" and then "late transition" modes to take advantage of the
+new, more futureproof NewHash object names.
+
+When objectFormat and compatObjectFormat are both set, commands
+generating signatures would generate both SHA-1 and NewHash signatures
+by default to support both new and old users.
+
+In projects using NewHash heavily, users could be encouraged to adopt
+the "post-transition" mode to avoid accidentally making implicit use
+of SHA-1 object names.
+
+Once a critical mass of users have upgraded to a version of Git that
+can verify NewHash signatures and have converted their existing
+repositories to support verifying them, we can add support for a
+setting to generate only NewHash signatures. This is expected to be at
+least a year later.
+
+That is also a good moment to advertise the ability to convert
+repositories to use NewHash only, stripping out all SHA-1 related
+metadata. This improves performance by eliminating translation
+overhead and security by avoiding the possibility of accidentally
+relying on the safety of SHA-1.
+
+Updating Git's protocols to allow a server to specify which hash
+functions it supports is also an important part of this transition. It
+is not discussed in detail in this document but this transition plan
+assumes it happens. :)
+
+Alternatives considered
+-----------------------
+Upgrading everyone working on a particular project on a flag day
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Projects like the Linux kernel are large and complex enough that
+flipping the switch for all projects based on the repository at once
+is infeasible.
+
+Not only would all developers and server operators supporting
+developers have to switch on the same flag day, but supporting tooling
+(continuous integration, code review, bug trackers, etc) would have to
+be adapted as well. This also makes it difficult to get early feedback
+from some project participants testing before it is time for mass
+adoption.
+
+Using hash functions in parallel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+(e.g. https://public-inbox.org/git/22708.8913.864049.452252@chiark.greenend.org.uk/ )
+Objects newly created would be addressed by the new hash, but inside
+such an object (e.g. commit) it is still possible to address objects
+using the old hash function.
+* You cannot trust its history (needed for bisectability) in the
+ future without further work
+* Maintenance burden as the number of supported hash functions grows
+ (they will never go away, so they accumulate). In this proposal, by
+ comparison, converted objects lose all references to SHA-1.
+
+Signed objects with multiple hashes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Instead of introducing the gpgsig-newhash field in commit and tag objects
+for newhash-content based signatures, an earlier version of this design
+added "hash newhash <newhash-name>" fields to strengthen the existing
+sha1-content based signatures.
+
+In other words, a single signature was used to attest to the object
+content using both hash functions. This had some advantages:
+* Using one signature instead of two speeds up the signing process.
+* Having one signed payload with both hashes allows the signer to
+ attest to the sha1-name and newhash-name referring to the same object.
+* All users consume the same signature. Broken signatures are likely
+ to be detected quickly using current versions of git.
+
+However, it also came with disadvantages:
+* Verifying a signed object requires access to the sha1-names of all
+ objects it references, even after the transition is complete and
+ translation table is no longer needed for anything else. To support
+ this, the design added fields such as "hash sha1 tree <sha1-name>"
+ and "hash sha1 parent <sha1-name>" to the newhash-content of a signed
+ commit, complicating the conversion process.
+* Allowing signed objects without a sha1 (for after the transition is
+ complete) complicated the design further, requiring a "nohash sha1"
+ field to suppress including "hash sha1" fields in the newhash-content
+ and signed payload.
+
+Lazily populated translation table
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some of the work of building the translation table could be deferred to
+push time, but that would significantly complicate and slow down pushes.
+Calculating the sha1-name at object creation time at the same time it is
+being streamed to disk and having its newhash-name calculated should be
+an acceptable cost.
