+Git 2.20 Release Notes
+======================
Backward Compatibility Notes
----------------------------
which means some fetches of tags that did not fail with older
version of Git will fail without "--force" with this version.
+ * "git help -a" now gives verbose output (same as "git help -av").
+ Those who want the old output may say "git help --no-verbose -a"..
+
+ * "git cpn --help", when "cpn" is an alias to, say, "cherry-pick -n",
+ reported only the alias expansion of "cpn" in earlier versions of
+ Git. It now runs "git cherry-pick --help" to show the manual page
+ of the command, while sending the alias expansion to the standard
+ error stream.
+
+ * "git send-email" learned to grab address-looking string on any
+ trailer whose name ends with "-by". This is a backward-incompatible
+ change. Adding "--suppress-cc=misc-by" on the command line, or
+ setting sendemail.suppresscc configuration variable to "misc-by",
+ can be used to disable this behaviour.
+
Updates since v2.19
-------------------
* "git format-patch" learned new "--interdiff" and "--range-diff"
options to explain the difference between this version and the
- previous attempt in the cover letter (or after the tree-dashes as
+ previous attempt in the cover letter (or after the three-dashes as
a comment).
* "git mailinfo" used in "git am" learned to make a best-effort
to be unmoving anchoring points. "git fetch" was taught to forbid
updates to existing tags without the "--force" option.
+ * "git multi-pack-index" learned to detect corruption in the .midx
+ file it uses, and this feature has been integrated into "git fsck".
+
+ * Generation of (experimental) commit-graph files have so far been
+ fairly silent, even though it takes noticeable amount of time in a
+ meaningfully large repository. The users will now see progress
+ output.
+
+ * The minimum version of Windows supported by Windows port of Git is
+ now set to Vista.
+
+ * The completion script (in contrib/) learned to complete a handful of
+ options "git stash list" command takes.
+
+ * The completion script (in contrib/) learned that "git fetch
+ --multiple" only takes remote names as arguments and no refspecs.
+
+ * "git status" learns to show progress bar when refreshing the index
+ takes a long time.
+ (merge ae9af12287 nd/status-refresh-progress later to maint).
+
+ * "git help -a" and "git help -av" give different pieces of
+ information, and generally the "verbose" version is more friendly
+ to the new users. "git help -a" by default now uses the more
+ verbose output (with "--no-verbose", you can go back to the
+ original). Also "git help -av" now lists aliases and external
+ commands, which it did not used to.
+
+ * Unlike "grep", "git grep" by default recurses to the whole tree.
+ The command learned "git grep --recursive" option, so that "git
+ grep --no-recursive" can serve as a synonym to setting the
+ max-depth to 0.
+
+ * When pushing into a repository that borrows its objects from an
+ alternate object store, "git receive-pack" that responds to the
+ push request on the other side lists the tips of refs in the
+ alternate to reduce the amount of objects transferred. This
+ sometimes is detrimental when the number of refs in the alternate
+ is absurdly large, in which case the bandwidth saved in potentially
+ fewer objects transferred is wasted in excessively large ref
+ advertisement. The alternate refs that are advertised are now
+ configurable with a pair of configuration variables.
+
+ * "git cmd --help" when "cmd" is aliased used to only say "cmd is
+ aliased to ...". Now it shows that to the standard error stream
+ and runs "git $cmd --help" where $cmd is the first word of the
+ alias expansion.
+
+ * The documentation of "git gc" has been updated to mention that it
+ is no longer limited to "pruning away crufts" but also updates
+ ancillary files like commit-graph as a part of repository
+ optimization.
+
+ * "git p4 unshelve" improvements.
+
+ * The logic to select the default user name and e-mail on Windows has
+ been improved.
+ (merge 501afcb8b0 js/mingw-default-ident later to maint).
+
+ * The "rev-list --filter" feature learned to exclude all trees via
+ "tree:0" filter.
+
+ * "git send-email" learned to grab address-looking string on any
+ trailer whose name ends with "-by"; --suppress-cc=misc-by on the
+ command line, or setting sendemail.suppresscc configuration
+ variable to "misc-by", can be used to disable this behaviour.
+
+ * "git mergetool" learned to take the "--[no-]gui" option, just like
+ "git difftool" does.
+
+ * "git rebase -i" learned a new insn, 'break', that the user can
+ insert in the to-do list. Upon hitting it, the command returns
+ control back to the user.
+
+ * New "--pretty=format:" placeholders %GF and %GP that show the GPG
+ key fingerprints have been invented.
+
+ * On platforms with recent cURL library, http.sslBackend configuration
+ variable can be used to choose a different SSL backend at runtime.
+ The Windows port uses this mechanism to switch between OpenSSL and
+ Secure Channel while talking over the HTTPS protocol.
+
+ * "git send-email" learned to disable SMTP authentication via the
+ "--smtp-auth=none" option, even when the smtp username is given
+ (which turns the authentication on by default).
+
+ * A fourth class of configuration files (in addition to the
+ traditional "system wide", "per user in the $HOME directory" and
+ "per repository in the $GIT_DIR/config") has been introduced so
+ that different worktrees that share the same repository (hence the
+ same $GIT_DIR/config file) can use different customization.
+
+ * A pattern with '**' that does not have a slash on either side used
+ to be an invalid one, but the code now treats such double-asterisks
+ the same way as two normal asterisks that happen to be adjacent to
+ each other.
+ (merge e5bbe09e88 nd/wildmatch-double-asterisk later to maint).
+
+ * The "--no-patch" option, which can be used to get a high-level
+ overview without the actual line-by-line patch difference shown, of
+ the "range-diff" command was earlier broken, which has been
+ corrected.
+
+ * The recently merged "rebase in C" has an escape hatch to use the
+ scripted version when necessary, but it hasn't been documented,
+ which has been corrected.
+
Performance, Internal Implementation, Development Support etc.
+ * Developer builds now use -Wunused-function compilation option.
+
+ * One of our CI tests to run with "unusual/experimental/random"
+ settings now also uses commit-graph and midx.
+
* When there are too many packfiles in a repository (which is not
recommended), looking up an object in these would require
consulting many pack .idx files; a new mechanism to have a single
manually). Also, as a convenience, expand the number of cases in
which --force is applicable.
+ * Split Documentation/config.txt for easier maintenance.
+ (merge 6014363f0b nd/config-split later to maint).
+
+ * Test helper binaries clean-up.
+ (merge c9a1f4161f nd/test-tool later to maint).
+
+ * Various tests have been updated to make it easier to swap the
+ hash function used for object identification.
+ (merge ae0c89d41b bc/hash-independent-tests later to maint).
+
+ * Update fsck.skipList implementation and documentation.
+ (merge 371a655074 ab/fsck-skiplist later to maint).
+
+ * An alias that expands to another alias has so far been forbidden,
+ but now it is allowed to create such an alias.
+
+ * Various test scripts have been updated for style and also correct
+ handling of exit status of various commands.
+
+ * "gc --auto" ended up calling exit(-1) upon error, which has been
+ corrected to use exit(1). Also the error reporting behaviour when
+ daemonized has been updated to exit with zero status when stopping
+ due to a previously discovered error (which implies there is no
+ point running gc to improve the situation); we used to exit with
+ failure in such a case.
+
+ * Various codepaths in the core-ish part learned to work on an
+ arbitrary in-core index structure, not necessarily the default
+ instance "the_index".
+ (merge b3c7eef9b0 nd/the-index later to maint).
+
+ * Code clean-up in the internal machinery used by "git status" and
+ "git commit --dry-run".
+ (merge 73ba5d78b4 ss/wt-status-committable later to maint).
+
+ * Some environment variables that control the runtime options of Git
+ used during tests are getting renamed for consistency.
+ (merge 4231d1ba99 bp/rename-test-env-var later to maint).
+
+ * A pair of new extensions to the index file have been introduced.
+ They allow the index file to be read in parallel for performance.
+
+ * The oidset API was built on top of the oidmap API which in turn is
+ on the hashmap API. Replace the implementation to build on top of
+ the khash API and gain performance.
+
+ * Over some transports, fetching objects with an exact commit object
+ name can be done without first seeing the ref advertisements. The
+ code has been optimized to exploit this.
+
+ * In a partial clone that will lazily be hydrated from the
+ originating repository, we generally want to avoid "does this
+ object exist (locally)?" on objects that we deliberately omitted
+ when we created the clone. The cache-tree codepath (which is used
+ to write a tree object out of the index) however insisted that the
+ object exists, even for paths that are outside of the partial
+ checkout area. The code has been updated to avoid such a check.
+
+ * To help developers, an EditorConfig file that attempts to follow
+ the project convention has been added.
+ (merge b548d698a0 bc/editorconfig later to maint).
+
+ * The result of coverage test can be combined with "git blame" to
+ check the test coverage of code introduced recently with a new
+ 'coverage-diff' tool (in contrib/).
+ (merge 783faedd65 ds/coverage-diff later to maint).
+
+ * An experiment to fuzz test a few areas, hopefully we can gain more
+ coverage to various areas.
+
+ * More codepaths are moving away from hardcoded hash sizes.
+
+ * The way the Windows port figures out the current directory has been
+ improved.
+
+ * The way DLLs are loaded on the Windows port has been improved.
+
+ * Some tests have been reorganized and renamed; "ls t/" now gives a
+ better overview of what is tested for these scripts than before.
+
+ * "git rebase" and "git rebase -i" have been reimplemented in C.
+
+ * Windows port learned to use nano-second resolution file timestamps.
+
+ * The overly large Documentation/config.txt file have been split into
+ million little pieces. This potentially allows each individual piece
+ to be included into the manual page of the command it affects more easily.
+
+ * Replace three string-list instances used as look-up tables in "git
+ fetch" with hashmaps.
+
+ * Unify code to read the author-script used in "git am" and the
+ commands that use the sequencer machinery, e.g. "git rebase -i".
+
+ * In preparation to the day when we can deprecate and remove the
+ "rebase -p", make sure we can skip and later remove tests for
+ it.
+
+ * The history traversal used to implement the tag-following has been
+ optimized by introducing a new helper.
+
+ * The helper function to refresh the cached stat information in the
+ in-core index has learned to perform the lstat() part of the
+ operation in parallel on multi-core platforms.
+
+ * The code to traverse objects for reachability, used to decide what
+ objects are unreferenced and expendable, have been taught to also
+ consider per-worktree refs of other worktrees as starting points to
+ prevent data loss.
+
+ * "git add" needs to internally run "diff-files" equivalent, and the
+ codepath learned the same optimization as "diff-files" has to run
+ lstat(2) in parallel to find which paths have been updated in the
+ working tree.
+
+ * The procedure to install dependencies before testing at Travis CI
+ is getting revamped for both simplicity and flexibility, taking
+ advantage of the recent move to the vm-based environment.
+
+ * The support for format-patch (and send-email) by the command-line
+ completion script (in contrib/) has been simplified a bit.
+
+ * The revision walker machinery learned to take advantage of the
+ commit generation numbers stored in the commit-graph file.
+
+ * The codebase has been cleaned up to reduce "#ifndef NO_PTHREADS".
+
+ * The way -lcurl library gets linked has been simplified by taking
+ advantage of the fact that we can just ask curl-config command how.
+
+ * Various functions have been audited for "-Wunused-parameter" warnings
+ and bugs in them got fixed.
+
+ * A sanity check for start-up sequence has been added in the config
+ API codepath.
+
+ * The build procedure to link for fuzzing test has been made
+ customizable with a new Makefile variable.
+
+ * The way "git rebase" parses and forwards the command line options
+ meant for underlying "git am" has been revamped, which fixed for
+ options with parameters that were not passed correctly.
+
+ * Our testing framework uses a special i18n "poisoned localization"
+ feature to find messages that ought to stay constant but are
+ incorrectly marked to be translated. This feature has been made
+ into a runtime option (it used to be a compile-time option).
+
+ * "git push" used to check ambiguities between object-names and
+ refnames while processing the list of refs' old and new values,
+ which was unnecessary (as it knew that it is feeding raw object
+ names). This has been optimized out.
+
+ * The xcurl_off_t() helper function is used to cast size_t to
+ curl_off_t, but some compilers gave warnings against the code to
+ ensure the casting is done without wraparound, when size_t is
+ narrower than curl_off_t. This warning has been squelched.
+
+ * Code preparation to replace ulong vars with size_t vars where
+ appropriate continues.
+
+ * The "test installed Git" mode of our test suite has been updated to
+ work better.
+
+ * A coding convention around the Coccinelle semantic patches to have
+ two classes to ease code migration process has been proposed and
+ its support has been added to the Makefile.
+
+ * The "container" mode of TravisCI is going away. Our .travis.yml
+ file is getting prepared for the transition.
+ (merge 32ee384be8 ss/travis-ci-force-vm-mode later to maint).
+
+ * Our test scripts can now take the '-V' option as a synonym for the
+ '--verbose-log' option.
+ (merge a5f52c6dab sg/test-verbose-log later to maint).
+
Fixes since v2.19
-----------------
segfault, which has been corrected.
(merge e467a90c7a tg/range-diff-corner-case-fix later to maint).
+ * The recently introduced commit-graph auxiliary data is incompatible
+ with mechanisms such as replace & grafts that "breaks" immutable
+ nature of the object reference relationship. Disable optimizations
+ based on its use (and updating existing commit-graph) when these
+ incompatible features are in use in the repository.
+ (merge 829a321569 ds/commit-graph-with-grafts later to maint).
+
+ * The mailmap file update.
+ (merge 255eb03edf jn/mailmap-update later to maint).
+
+ * The code in "git status" sometimes hit an assertion failure. This
+ was caused by a structure that was reused without cleaning the data
+ used for the first run, which has been corrected.
+ (merge 3e73cc62c0 en/status-multiple-renames-to-the-same-target-fix later to maint).
+
+ * "git fetch $repo $object" in a partial clone did not correctly
+ fetch the asked-for object that is referenced by an object in
+ promisor packfile, which has been fixed.
+
+ * A corner-case bugfix.
+ (merge c5cbb27cb5 sm/show-superproject-while-conflicted later to maint).
+
+ * Various fixes to "diff --color-moved-ws".
+
+ * A partial clone that is configured to lazily fetch missing objects
+ will on-demand issue a "git fetch" request to the originating
+ repository to fill not-yet-obtained objects. The request has been
+ optimized for requesting a tree object (and not the leaf blob
+ objects contained in it) by telling the originating repository that
+ no blobs are needed.
+ (merge 4c7f9567ea jt/non-blob-lazy-fetch later to maint).
+
+ * The codepath to support the experimental split-index mode had
+ remaining "racily clean" issues fixed.
+ (merge 4c490f3d32 sg/split-index-racefix later to maint).
+
+ * "git log --graph" showing an octopus merge sometimes miscounted the
+ number of display columns it is consuming to show the merge and its
+ parent commits, which has been corrected.
+ (merge 04005834ed np/log-graph-octopus-fix later to maint).
+
+ * "git range-diff" did not work well when the compared ranges had
+ changes in submodules and the "--submodule=log" was used.
+
+ * The implementation of run_command() API on the UNIX platforms had a
+ bug that caused a command not on $PATH to be found in the current
+ directory.
+ (merge f67b980771 jk/run-command-notdot later to maint).
+
+ * A mutex used in "git pack-objects" were not correctly initialized
+ and this caused "git repack" to dump core on Windows.
+ (merge 34204c8166 js/pack-objects-mutex-init-fix later to maint).
+
+ * Under certain circumstances, "git diff D:/a/b/c D:/a/b/d" on
+ Windows would strip initial parts from the paths because they
+ were not recognized as absolute, which has been corrected.
+ (merge ffd04e92e2 js/diff-notice-has-drive-prefix later to maint).
+
+ * The receive.denyCurrentBranch=updateInstead codepath kicked in even
+ when the push should have been rejected due to other reasons, such
+ as it does not fast-forward or the update-hook rejects it, which
+ has been corrected.
+ (merge b072a25fad jc/receive-deny-current-branch-fix later to maint).
+
+ * The logic to determine the archive type "git archive" uses did not
+ correctly kick in for "git archive --remote", which has been
+ corrected.
+
+ * "git repack" in a shallow clone did not correctly update the
+ shallow points in the repository, leading to a repository that
+ does not pass fsck.
+ (merge 5dcfbf564c js/shallow-and-fetch-prune later to maint).
+
+ * Some codepaths failed to form a proper URL when .gitmodules record
+ the URL to a submodule repository as relative to the repository of
+ superproject, which has been corrected.
+ (merge e0a862fdaf sb/submodule-url-to-absolute later to maint).
+
+ * "git fetch" over protocol v2 into a shallow repository failed to
+ fetch full history behind a new tip of history that was diverged
+ before the cut-off point of the history that was previously fetched
+ shallowly.
+
+ * The command line completion machinery (in contrib/) has been
+ updated to allow the completion script to tweak the list of options
+ that are reported by the parse-options machinery correctly.
+ (merge 276b49ff34 nd/completion-negation later to maint).
+
+ * Operations on promisor objects make sense in the context of only a
+ small subset of the commands that internally use the revisions
+ machinery, but the "--exclude-promisor-objects" option were taken
+ and led to nonsense results by commands like "log", to which it
+ didn't make much sense. This has been corrected.
+ (merge 669b1d2aae md/exclude-promisor-objects-fix later to maint).
+
+ * A regression in Git 2.12 era made "git fsck" fall into an infinite
+ loop while processing truncated loose objects.
+ (merge 18ad13e5b2 jk/detect-truncated-zlib-input later to maint).
+
+ * "git ls-remote $there foo" was broken by recent update for the
+ protocol v2 and stopped showing refs that match 'foo' that are not
+ refs/{heads,tags}/foo, which has been fixed.
+ (merge 6a139cdd74 jk/proto-v2-ref-prefix-fix later to maint).
+
+ * Additional comment on a tricky piece of code to help developers.
+ (merge 0afbe3e806 jk/stream-pack-non-delta-clarification later to maint).
+
+ * A couple of tests used to leave the repository in a state that is
+ deliberately corrupt, which have been corrected.
+ (merge aa984dbe5e ab/pack-tests-cleanup later to maint).
+
+ * The submodule support has been updated to read from the blob at
+ HEAD:.gitmodules when the .gitmodules file is missing from the
+ working tree.
+ (merge 2b1257e463 ao/submodule-wo-gitmodules-checked-out later to maint).
+
+ * "git fetch" was a bit loose in parsing responses from the other side
+ when talking over the protocol v2.
+
+ * "git rev-parse --exclude=* --branches --branches" (i.e. first
+ saying "add only things that do not match '*' out of all branches"
+ and then adding all branches, without any exclusion this time)
+ worked as expected, but "--exclude=* --all --all" did not work the
+ same way, which has been fixed.
+ (merge 5221048092 ag/rev-parse-all-exclude-fix later to maint).
+
+ * "git send-email --transfer-encoding=..." in recent versions of Git
+ sometimes produced an empty "Content-Transfer-Encoding:" header,
+ which has been corrected.
+ (merge 3c88e46f1a al/send-email-auto-cte-fixup later to maint).
+
+ * The interface into "xdiff" library used to discover the offset and
+ size of a generated patch hunk by first formatting it into the
+ textual hunk header "@@ -n,m +k,l @@" and then parsing the numbers
+ out. A new interface has been introduced to allow callers a more
+ direct access to them.
+ (merge 5eade0746e jk/xdiff-interface later to maint).
+
+ * Pathspec matching against a tree object were buggy when negative
+ pathspec elements were involved, which has been fixed.
+ (merge b7845cebc0 nd/tree-walk-path-exclusion later to maint).
+
+ * "git merge" and "git pull" that merges into an unborn branch used
+ to completely ignore "--verify-signatures", which has been
+ corrected.
+ (merge 01a31f3bca jk/verify-sig-merge-into-void later to maint).
+
+ * "git rebase --autostash" did not correctly re-attach the HEAD at times.
+
+ * "rev-parse --exclude=<pattern> --branches=<pattern>" etc. did not
+ quite work, which has been corrected.
+ (merge 9ab9b5df0e ra/rev-parse-exclude-glob later to maint).
+
+ * When editing a patch in a "git add -i" session, a hunk could be
+ made to no-op. The "git apply" program used to reject a patch with
+ such a no-op hunk to catch user mistakes, but it is now updated to
+ explicitly allow a no-op hunk in an edited patch.
+ (merge 22cb3835b9 js/apply-recount-allow-noop later to maint).
+
+ * The URL to an MSDN page in a comment has been updated.
+ (merge 2ef2ae2917 js/mingw-msdn-url later to maint).
+
+ * "git ls-remote --sort=<thing>" can feed an object that is not yet
+ available into the comparison machinery and segfault, which has
+ been corrected to check such a request upfront and reject it.
+
+ * When "git bundle" aborts due to an empty commit ranges
+ (i.e. resulting in an empty pack), it left a file descriptor to an
+ lockfile open, which resulted in leftover lockfile on Windows where
+ you cannot remove a file with an open file descriptor. This has
+ been corrected.
+ (merge 2c8ee1f53c jk/close-duped-fd-before-unlock-for-bundle later to maint).
+
+ * "git format-patch --stat=<width>" can be used to specify the width
+ used by the diffstat (shown in the cover letter).
+ (merge 284aeb7e60 nd/format-patch-cover-letter-stat-width later to maint).
+
+ * The way .git/index and .git/sharedindex* files were initially
+ created gave these files different perm bits until they were
+ adjusted for shared repository settings. This was made consistent.
+ (merge c9d6c78870 cc/shared-index-permbits later to maint).
+
+ * "git rebase --stat" to transplant a piece of history onto a totally
+ unrelated history were not working before and silently showed wrong
+ result. With the recent reimplementation in C, it started to instead
+ die with an error message, as the original logic was not prepared
+ to cope with this case. This has now been fixed.
+
+ * The advice message to tell the user to migrate an existing graft
+ file to the replace system when a graft file was read was shown
+ even when "git replace --convert-graft-file" command, which is the
+ way the message suggests to use, was running, which made little
+ sense.
+ (merge 8821e90a09 ab/replace-graft-with-replace-advice later to maint).
+
+ * "git diff --raw" lost ellipses to adjust the output columns for
+ some time now, but the documentation still showed them.
+
* Code cleanup, docfix, build fix, etc.
