1 Git 2.20 Release Notes
2 ======================
4 Backward Compatibility Notes
5 ----------------------------
7 * "git branch -l <foo>" used to be a way to ask a reflog to be
8 created while creating a new branch, but that is no longer the
9 case. It is a short-hand for "git branch --list <foo>" now.
11 * "git push" into refs/tags/* hierarchy is rejected without getting
12 forced, but "git fetch" (misguidedly) used the "fast forwarding"
13 rule used for the refs/heads/* hierarchy; this has been corrected,
14 which means some fetches of tags that did not fail with older
15 version of Git will fail without "--force" with this version.
17 * "git help -a" now gives verbose output (same as "git help -av").
18 Those who want the old output may say "git help --no-verbose -a"..
20 * "git cpn --help", when "cpn" is an alias to, say, "cherry-pick -n",
21 reported only the alias expansion of "cpn" in earlier versions of
22 Git. It now runs "git cherry-pick --help" to show the manual page
23 of the command, while sending the alias expansion to the standard
24 error stream.
26 * "git send-email" learned to grab address-looking string on any
27 trailer whose name ends with "-by". This is a backward-incompatible
28 change. Adding "--suppress-cc=misc-by" on the command line, or
29 setting sendemail.suppresscc configuration variable to "misc-by",
30 can be used to disable this behaviour.
33 Updates since v2.19
34 -------------------
36 UI, Workflows & Features
38 * Running "git clone" against a project that contain two files with
39 pathnames that differ only in cases on a case insensitive
40 filesystem would result in one of the files lost because the
41 underlying filesystem is incapable of holding both at the same
42 time. An attempt is made to detect such a case and warn.
44 * "git checkout -b newbranch [HEAD]" should not have to do as much as
45 checking out a commit different from HEAD. An attempt is made to
46 optimize this special case.
48 * "git rev-list --stdin </dev/null" used to be an error; it now shows
49 no output without an error. "git rev-list --stdin --default HEAD"
50 still falls back to the given default when nothing is given on the
51 standard input.
53 * Lift code from GitHub to restrict delta computation so that an
54 object that exists in one fork is not made into a delta against
55 another object that does not appear in the same forked repository.
57 * "git format-patch" learned new "--interdiff" and "--range-diff"
58 options to explain the difference between this version and the
59 previous attempt in the cover letter (or after the three-dashes as
60 a comment).
62 * "git mailinfo" used in "git am" learned to make a best-effort
63 recovery of a patch corrupted by MUA that sends text/plain with
64 format=flawed option.
65 (merge 3aa4d81f88 rs/mailinfo-format-flowed later to maint).
67 * The rules used by "git push" and "git fetch" to determine if a ref
68 can or cannot be updated were inconsistent; specifically, fetching
69 to update existing tags were allowed even though tags are supposed
70 to be unmoving anchoring points. "git fetch" was taught to forbid
71 updates to existing tags without the "--force" option.
73 * "git multi-pack-index" learned to detect corruption in the .midx
74 file it uses, and this feature has been integrated into "git fsck".
76 * Generation of (experimental) commit-graph files have so far been
77 fairly silent, even though it takes noticeable amount of time in a
78 meaningfully large repository. The users will now see progress
79 output.
81 * The minimum version of Windows supported by Windows port of Git is
82 now set to Vista.
84 * The completion script (in contrib/) learned to complete a handful of
85 options "git stash list" command takes.
87 * The completion script (in contrib/) learned that "git fetch
88 --multiple" only takes remote names as arguments and no refspecs.
90 * "git status" learns to show progress bar when refreshing the index
91 takes a long time.
92 (merge ae9af12287 nd/status-refresh-progress later to maint).
94 * "git help -a" and "git help -av" give different pieces of
95 information, and generally the "verbose" version is more friendly
96 to the new users. "git help -a" by default now uses the more
97 verbose output (with "--no-verbose", you can go back to the
98 original). Also "git help -av" now lists aliases and external
99 commands, which it did not used to.
101 * Unlike "grep", "git grep" by default recurses to the whole tree.
102 The command learned "git grep --recursive" option, so that "git
103 grep --no-recursive" can serve as a synonym to setting the
104 max-depth to 0.
106 * When pushing into a repository that borrows its objects from an
107 alternate object store, "git receive-pack" that responds to the
108 push request on the other side lists the tips of refs in the
109 alternate to reduce the amount of objects transferred. This
110 sometimes is detrimental when the number of refs in the alternate
111 is absurdly large, in which case the bandwidth saved in potentially
112 fewer objects transferred is wasted in excessively large ref
113 advertisement. The alternate refs that are advertised are now
114 configurable with a pair of configuration variables.
116 * "git cmd --help" when "cmd" is aliased used to only say "cmd is
117 aliased to ...". Now it shows that to the standard error stream
118 and runs "git $cmd --help" where $cmd is the first word of the
119 alias expansion.
121 * The documentation of "git gc" has been updated to mention that it
122 is no longer limited to "pruning away cruft" but also updates
123 ancillary files like commit-graph as a part of repository
124 optimization.
126 * "git p4 unshelve" improvements.
128 * The logic to select the default user name and e-mail on Windows has
129 been improved.
130 (merge 501afcb8b0 js/mingw-default-ident later to maint).
132 * The "rev-list --filter" feature learned to exclude all trees via
133 "tree:0" filter.
135 * "git send-email" learned to grab address-looking string on any
136 trailer whose name ends with "-by"; --suppress-cc=misc-by on the
137 command line, or setting sendemail.suppresscc configuration
138 variable to "misc-by", can be used to disable this behaviour.
140 * "git mergetool" learned to take the "--[no-]gui" option, just like
141 "git difftool" does.
143 * "git rebase -i" learned a new insn, 'break', that the user can
144 insert in the to-do list. Upon hitting it, the command returns
145 control back to the user.
147 * New "--pretty=format:" placeholders %GF and %GP that show the GPG
148 key fingerprints have been invented.
150 * On platforms with recent cURL library, http.sslBackend configuration
151 variable can be used to choose a different SSL backend at runtime.
152 The Windows port uses this mechanism to switch between OpenSSL and
153 Secure Channel while talking over the HTTPS protocol.
155 * "git send-email" learned to disable SMTP authentication via the
156 "--smtp-auth=none" option, even when the smtp username is given
157 (which turns the authentication on by default).
159 * A fourth class of configuration files (in addition to the
160 traditional "system wide", "per user in the $HOME directory" and
161 "per repository in the $GIT_DIR/config") has been introduced so
162 that different worktrees that share the same repository (hence the
163 same $GIT_DIR/config file) can use different customization.
165 * A pattern with '**' that does not have a slash on either side used
166 to be an invalid one, but the code now treats such double-asterisks
167 the same way as two normal asterisks that happen to be adjacent to
168 each other.
169 (merge e5bbe09e88 nd/wildmatch-double-asterisk later to maint).
171 * The "--no-patch" option, which can be used to get a high-level
172 overview without the actual line-by-line patch difference shown, of
173 the "range-diff" command was earlier broken, which has been
174 corrected.
176 * The recently merged "rebase in C" has an escape hatch to use the
177 scripted version when necessary, but it hasn't been documented,
178 which has been corrected.
181 Performance, Internal Implementation, Development Support etc.
183 * Developer builds now use -Wunused-function compilation option.
185 * One of our CI tests to run with "unusual/experimental/random"
186 settings now also uses commit-graph and midx.
188 * When there are too many packfiles in a repository (which is not
189 recommended), looking up an object in these would require
190 consulting many pack .idx files; a new mechanism to have a single
191 file that consolidates all of these .idx files is introduced.
193 * "git submodule update" is getting rewritten piece-by-piece into C.
195 * The code for computing history reachability has been shuffled,
196 obtained a bunch of new tests to cover them, and then being
197 improved.
199 * The unpack_trees() API used in checking out a branch and merging
200 walks one or more trees along with the index. When the cache-tree
201 in the index tells us that we are walking a tree whose flattened
202 contents is known (i.e. matches a span in the index), as linearly
203 scanning a span in the index is much more efficient than having to
204 open tree objects recursively and listing their entries, the walk
205 can be optimized, which has been done.
207 * When creating a thin pack, which allows objects to be made into a
208 delta against another object that is not in the resulting pack but
209 is known to be present on the receiving end, the code learned to
210 take advantage of the reachability bitmap; this allows the server
211 to send a delta against a base beyond the "boundary" commit.
213 * spatch transformation to replace boolean uses of !hashcmp() to
214 newly introduced oideq() is added, and applied, to regain
215 performance lost due to support of multiple hash algorithms.
217 * Fix a bug in which the same path could be registered under multiple
218 worktree entries if the path was missing (for instance, was removed
219 manually). Also, as a convenience, expand the number of cases in
220 which --force is applicable.
222 * Split Documentation/config.txt for easier maintenance.
223 (merge 6014363f0b nd/config-split later to maint).
225 * Test helper binaries clean-up.
226 (merge c9a1f4161f nd/test-tool later to maint).
228 * Various tests have been updated to make it easier to swap the
229 hash function used for object identification.
230 (merge ae0c89d41b bc/hash-independent-tests later to maint).
232 * Update fsck.skipList implementation and documentation.
233 (merge 371a655074 ab/fsck-skiplist later to maint).
235 * An alias that expands to another alias has so far been forbidden,
236 but now it is allowed to create such an alias.
238 * Various test scripts have been updated for style and also correct
239 handling of exit status of various commands.
241 * "gc --auto" ended up calling exit(-1) upon error, which has been
242 corrected to use exit(1). Also the error reporting behaviour when
243 daemonized has been updated to exit with zero status when stopping
244 due to a previously discovered error (which implies there is no
245 point running gc to improve the situation); we used to exit with
246 failure in such a case.
248 * Various codepaths in the core-ish part learned to work on an
249 arbitrary in-core index structure, not necessarily the default
250 instance "the_index".
251 (merge b3c7eef9b0 nd/the-index later to maint).
253 * Code clean-up in the internal machinery used by "git status" and
254 "git commit --dry-run".
255 (merge 73ba5d78b4 ss/wt-status-committable later to maint).
257 * Some environment variables that control the runtime options of Git
258 used during tests are getting renamed for consistency.
259 (merge 4231d1ba99 bp/rename-test-env-var later to maint).
261 * A pair of new extensions to the index file have been introduced.
262 They allow the index file to be read in parallel for performance.
264 * The oidset API was built on top of the oidmap API which in turn is
265 on the hashmap API. Replace the implementation to build on top of
266 the khash API and gain performance.
268 * Over some transports, fetching objects with an exact commit object
269 name can be done without first seeing the ref advertisements. The
270 code has been optimized to exploit this.
272 * In a partial clone that will lazily be hydrated from the
273 originating repository, we generally want to avoid "does this
274 object exist (locally)?" on objects that we deliberately omitted
275 when we created the clone. The cache-tree codepath (which is used
276 to write a tree object out of the index) however insisted that the
277 object exists, even for paths that are outside of the partial
278 checkout area. The code has been updated to avoid such a check.
280 * To help developers, an EditorConfig file that attempts to follow
281 the project convention has been added.
282 (merge b548d698a0 bc/editorconfig later to maint).
284 * The result of coverage test can be combined with "git blame" to
285 check the test coverage of code introduced recently with a new
286 'coverage-diff' tool (in contrib/).
287 (merge 783faedd65 ds/coverage-diff later to maint).
289 * An experiment to fuzz test a few areas, hopefully we can gain more
290 coverage to various areas.
292 * More codepaths are moving away from hardcoded hash sizes.
294 * The way the Windows port figures out the current directory has been
295 improved.
297 * The way DLLs are loaded on the Windows port has been improved.
299 * Some tests have been reorganized and renamed; "ls t/" now gives a
300 better overview of what is tested for these scripts than before.
302 * "git rebase" and "git rebase -i" have been reimplemented in C.
304 * Windows port learned to use nano-second resolution file timestamps.
306 * The overly large Documentation/config.txt file have been split into
307 million little pieces. This potentially allows each individual piece
308 to be included into the manual page of the command it affects more easily.
310 * Replace three string-list instances used as look-up tables in "git
311 fetch" with hashmaps.
313 * Unify code to read the author-script used in "git am" and the
314 commands that use the sequencer machinery, e.g. "git rebase -i".
316 * In preparation to the day when we can deprecate and remove the
317 "rebase -p", make sure we can skip and later remove tests for
318 it.
320 * The history traversal used to implement the tag-following has been
321 optimized by introducing a new helper.
323 * The helper function to refresh the cached stat information in the
324 in-core index has learned to perform the lstat() part of the
325 operation in parallel on multi-core platforms.
327 * The code to traverse objects for reachability, used to decide what
328 objects are unreferenced and expendable, have been taught to also
329 consider per-worktree refs of other worktrees as starting points to
330 prevent data loss.
332 * "git add" needs to internally run "diff-files" equivalent, and the
333 codepath learned the same optimization as "diff-files" has to run
334 lstat(2) in parallel to find which paths have been updated in the
335 working tree.
337 * The procedure to install dependencies before testing at Travis CI
338 is getting revamped for both simplicity and flexibility, taking
339 advantage of the recent move to the vm-based environment.
341 * The support for format-patch (and send-email) by the command-line
342 completion script (in contrib/) has been simplified a bit.
344 * The revision walker machinery learned to take advantage of the
345 commit generation numbers stored in the commit-graph file.
347 * The codebase has been cleaned up to reduce "#ifndef NO_PTHREADS".
349 * The way -lcurl library gets linked has been simplified by taking
350 advantage of the fact that we can just ask curl-config command how.
352 * Various functions have been audited for "-Wunused-parameter" warnings
353 and bugs in them got fixed.
355 * A sanity check for start-up sequence has been added in the config
356 API codepath.
358 * The build procedure to link for fuzzing test has been made
359 customizable with a new Makefile variable.
361 * The way "git rebase" parses and forwards the command line options
362 meant for underlying "git am" has been revamped, which fixed for
363 options with parameters that were not passed correctly.
365 * Our testing framework uses a special i18n "poisoned localization"
366 feature to find messages that ought to stay constant but are
367 incorrectly marked to be translated. This feature has been made
368 into a runtime option (it used to be a compile-time option).
370 * "git push" used to check ambiguities between object-names and
371 refnames while processing the list of refs' old and new values,
372 which was unnecessary (as it knew that it is feeding raw object
373 names). This has been optimized out.
375 * The xcurl_off_t() helper function is used to cast size_t to
376 curl_off_t, but some compilers gave warnings against the code to
377 ensure the casting is done without wraparound, when size_t is
378 narrower than curl_off_t. This warning has been squelched.
380 * Code preparation to replace ulong vars with size_t vars where
381 appropriate continues.
383 * The "test installed Git" mode of our test suite has been updated to
384 work better.
386 * A coding convention around the Coccinelle semantic patches to have
387 two classes to ease code migration process has been proposed and
388 its support has been added to the Makefile.
390 * The "container" mode of TravisCI is going away. Our .travis.yml
391 file is getting prepared for the transition.
392 (merge 32ee384be8 ss/travis-ci-force-vm-mode later to maint).
394 * Our test scripts can now take the '-V' option as a synonym for the
395 '--verbose-log' option.
396 (merge a5f52c6dab sg/test-verbose-log later to maint).
399 Fixes since v2.19
400 -----------------
402 * "git interpret-trailers" and its underlying machinery had a buggy
403 code that attempted to ignore patch text after commit log message,
404 which triggered in various codepaths that will always get the log
405 message alone and never get such an input.
406 (merge 66e83d9b41 jk/trailer-fixes later to maint).
408 * Malformed or crafted data in packstream can make our code attempt
409 to read or write past the allocated buffer and abort, instead of
410 reporting an error, which has been fixed.
412 * "git rebase -i" did not clear the state files correctly when a run
413 of "squash/fixup" is aborted and then the user manually amended the
414 commit instead, which has been corrected.
415 (merge 10d2f35436 js/rebase-i-autosquash-fix later to maint).
417 * When fsmonitor is in use, after operation on submodules updates
418 .gitmodules, we lost track of the fact that we did so and relied on
419 stale fsmonitor data.
420 (merge 43f1180814 bp/mv-submodules-with-fsmonitor later to maint).
422 * Fix for a long-standing bug that leaves the index file corrupt when
423 it shrinks during a partial commit.
424 (merge 6c003d6ffb jk/reopen-tempfile-truncate later to maint).
426 * Further fix for O_APPEND emulation on Windows
427 (merge eeaf7ddac7 js/mingw-o-append later to maint).
429 * A corner case bugfix in "git rerere" code.
430 (merge ad2bf0d9b4 en/rerere-multi-stage-1-fix later to maint).
432 * "git add ':(attr:foo)'" is not supported and is supposed to be
433 rejected while the command line arguments are parsed, but we fail
434 to reject such a command line upfront.
435 (merge 84d938b732 nd/attr-pathspec-fix later to maint).
437 * Recent update broke the reachability algorithm when refs (e.g.
438 tags) that point at objects that are not commit were involved,
439 which has been fixed.
441 * "git rebase" etc. in Git 2.19 fails to abort when given an empty
442 commit log message as result of editing, which has been corrected.
443 (merge a3ec9eaf38 en/sequencer-empty-edit-result-aborts later to maint).
445 * The code to backfill objects in lazily cloned repository did not
446 work correctly, which has been corrected.
447 (merge e68302011c jt/lazy-object-fetch-fix later to maint).
449 * Update error messages given by "git remote" and make them consistent.
450 (merge 5025425dff ms/remote-error-message-update later to maint).
452 * "git update-ref" learned to make both "--no-deref" and "--stdin"
453 work at the same time.
454 (merge d345e9fbe7 en/update-ref-no-deref-stdin later to maint).
456 * Recently added "range-diff" had a corner-case bug to cause it
457 segfault, which has been corrected.
458 (merge e467a90c7a tg/range-diff-corner-case-fix later to maint).
460 * The recently introduced commit-graph auxiliary data is incompatible
461 with mechanisms such as replace & grafts that "breaks" immutable
462 nature of the object reference relationship. Disable optimizations
463 based on its use (and updating existing commit-graph) when these
464 incompatible features are in use in the repository.
465 (merge 829a321569 ds/commit-graph-with-grafts later to maint).
467 * The mailmap file update.
468 (merge 255eb03edf jn/mailmap-update later to maint).
470 * The code in "git status" sometimes hit an assertion failure. This
471 was caused by a structure that was reused without cleaning the data
472 used for the first run, which has been corrected.
473 (merge 3e73cc62c0 en/status-multiple-renames-to-the-same-target-fix later to maint).
475 * "git fetch $repo $object" in a partial clone did not correctly
476 fetch the asked-for object that is referenced by an object in
477 promisor packfile, which has been fixed.
479 * A corner-case bugfix.
480 (merge c5cbb27cb5 sm/show-superproject-while-conflicted later to maint).
482 * Various fixes to "diff --color-moved-ws".
484 * A partial clone that is configured to lazily fetch missing objects
485 will on-demand issue a "git fetch" request to the originating
486 repository to fill not-yet-obtained objects. The request has been
487 optimized for requesting a tree object (and not the leaf blob
488 objects contained in it) by telling the originating repository that
489 no blobs are needed.
490 (merge 4c7f9567ea jt/non-blob-lazy-fetch later to maint).
492 * The codepath to support the experimental split-index mode had
493 remaining "racily clean" issues fixed.
494 (merge 4c490f3d32 sg/split-index-racefix later to maint).
496 * "git log --graph" showing an octopus merge sometimes miscounted the
497 number of display columns it is consuming to show the merge and its
498 parent commits, which has been corrected.
499 (merge 04005834ed np/log-graph-octopus-fix later to maint).
501 * "git range-diff" did not work well when the compared ranges had
502 changes in submodules and the "--submodule=log" was used.
504 * The implementation of run_command() API on the UNIX platforms had a
505 bug that caused a command not on $PATH to be found in the current
506 directory.
507 (merge f67b980771 jk/run-command-notdot later to maint).
509 * A mutex used in "git pack-objects" were not correctly initialized
510 and this caused "git repack" to dump core on Windows.
511 (merge 34204c8166 js/pack-objects-mutex-init-fix later to maint).
513 * Under certain circumstances, "git diff D:/a/b/c D:/a/b/d" on
514 Windows would strip initial parts from the paths because they
515 were not recognized as absolute, which has been corrected.
516 (merge ffd04e92e2 js/diff-notice-has-drive-prefix later to maint).
518 * The receive.denyCurrentBranch=updateInstead codepath kicked in even
519 when the push should have been rejected due to other reasons, such
520 as it does not fast-forward or the update-hook rejects it, which
521 has been corrected.
522 (merge b072a25fad jc/receive-deny-current-branch-fix later to maint).
524 * The logic to determine the archive type "git archive" uses did not
525 correctly kick in for "git archive --remote", which has been
526 corrected.
528 * "git repack" in a shallow clone did not correctly update the
529 shallow points in the repository, leading to a repository that
530 does not pass fsck.
531 (merge 5dcfbf564c js/shallow-and-fetch-prune later to maint).
533 * Some codepaths failed to form a proper URL when .gitmodules record
534 the URL to a submodule repository as relative to the repository of
535 superproject, which has been corrected.
536 (merge e0a862fdaf sb/submodule-url-to-absolute later to maint).
538 * "git fetch" over protocol v2 into a shallow repository failed to
539 fetch full history behind a new tip of history that was diverged
540 before the cut-off point of the history that was previously fetched
541 shallowly.
543 * The command line completion machinery (in contrib/) has been
544 updated to allow the completion script to tweak the list of options
545 that are reported by the parse-options machinery correctly.
546 (merge 276b49ff34 nd/completion-negation later to maint).
548 * Operations on promisor objects make sense in the context of only a
549 small subset of the commands that internally use the revisions
550 machinery, but the "--exclude-promisor-objects" option were taken
551 and led to nonsense results by commands like "log", to which it
552 didn't make much sense. This has been corrected.
553 (merge 669b1d2aae md/exclude-promisor-objects-fix later to maint).
555 * A regression in Git 2.12 era made "git fsck" fall into an infinite
556 loop while processing truncated loose objects.
557 (merge 18ad13e5b2 jk/detect-truncated-zlib-input later to maint).
559 * "git ls-remote $there foo" was broken by recent update for the
560 protocol v2 and stopped showing refs that match 'foo' that are not
561 refs/{heads,tags}/foo, which has been fixed.
562 (merge 6a139cdd74 jk/proto-v2-ref-prefix-fix later to maint).
564 * Additional comment on a tricky piece of code to help developers.
565 (merge 0afbe3e806 jk/stream-pack-non-delta-clarification later to maint).
567 * A couple of tests used to leave the repository in a state that is
568 deliberately corrupt, which have been corrected.
569 (merge aa984dbe5e ab/pack-tests-cleanup later to maint).
571 * The submodule support has been updated to read from the blob at
572 HEAD:.gitmodules when the .gitmodules file is missing from the
573 working tree.
574 (merge 2b1257e463 ao/submodule-wo-gitmodules-checked-out later to maint).
576 * "git fetch" was a bit loose in parsing responses from the other side
577 when talking over the protocol v2.
579 * "git rev-parse --exclude=* --branches --branches" (i.e. first
580 saying "add only things that do not match '*' out of all branches"
581 and then adding all branches, without any exclusion this time)
582 worked as expected, but "--exclude=* --all --all" did not work the
583 same way, which has been fixed.
584 (merge 5221048092 ag/rev-parse-all-exclude-fix later to maint).
586 * "git send-email --transfer-encoding=..." in recent versions of Git
587 sometimes produced an empty "Content-Transfer-Encoding:" header,
588 which has been corrected.
589 (merge 3c88e46f1a al/send-email-auto-cte-fixup later to maint).
591 * The interface into "xdiff" library used to discover the offset and
592 size of a generated patch hunk by first formatting it into the
593 textual hunk header "@@ -n,m +k,l @@" and then parsing the numbers
594 out. A new interface has been introduced to allow callers a more
595 direct access to them.
596 (merge 5eade0746e jk/xdiff-interface later to maint).
598 * Pathspec matching against a tree object were buggy when negative
599 pathspec elements were involved, which has been fixed.
600 (merge b7845cebc0 nd/tree-walk-path-exclusion later to maint).
602 * "git merge" and "git pull" that merges into an unborn branch used
603 to completely ignore "--verify-signatures", which has been
604 corrected.
605 (merge 01a31f3bca jk/verify-sig-merge-into-void later to maint).
607 * "git rebase --autostash" did not correctly re-attach the HEAD at times.
609 * "rev-parse --exclude=<pattern> --branches=<pattern>" etc. did not
610 quite work, which has been corrected.
611 (merge 9ab9b5df0e ra/rev-parse-exclude-glob later to maint).
613 * When editing a patch in a "git add -i" session, a hunk could be
614 made to no-op. The "git apply" program used to reject a patch with
615 such a no-op hunk to catch user mistakes, but it is now updated to
616 explicitly allow a no-op hunk in an edited patch.
617 (merge 22cb3835b9 js/apply-recount-allow-noop later to maint).
619 * The URL to an MSDN page in a comment has been updated.
620 (merge 2ef2ae2917 js/mingw-msdn-url later to maint).
622 * "git ls-remote --sort=<thing>" can feed an object that is not yet
623 available into the comparison machinery and segfault, which has
624 been corrected to check such a request upfront and reject it.
626 * When "git bundle" aborts due to an empty commit ranges
627 (i.e. resulting in an empty pack), it left a file descriptor to an
628 lockfile open, which resulted in leftover lockfile on Windows where
629 you cannot remove a file with an open file descriptor. This has
630 been corrected.
631 (merge 2c8ee1f53c jk/close-duped-fd-before-unlock-for-bundle later to maint).
633 * "git format-patch --stat=<width>" can be used to specify the width
634 used by the diffstat (shown in the cover letter).
635 (merge 284aeb7e60 nd/format-patch-cover-letter-stat-width later to maint).
637 * The way .git/index and .git/sharedindex* files were initially
638 created gave these files different perm bits until they were
639 adjusted for shared repository settings. This was made consistent.
640 (merge c9d6c78870 cc/shared-index-permbits later to maint).
642 * "git rebase --stat" to transplant a piece of history onto a totally
643 unrelated history were not working before and silently showed wrong
644 result. With the recent reimplementation in C, it started to instead
645 die with an error message, as the original logic was not prepared
646 to cope with this case. This has now been fixed.
648 * The advice message to tell the user to migrate an existing graft
649 file to the replace system when a graft file was read was shown
650 even when "git replace --convert-graft-file" command, which is the
651 way the message suggests to use, was running, which made little
652 sense.
653 (merge 8821e90a09 ab/replace-graft-with-replace-advice later to maint).
655 * "git diff --raw" lost ellipses to adjust the output columns for
656 some time now, but the documentation still showed them.
658 * Code cleanup, docfix, build fix, etc.
