1Git 2.20 Release Notes 2====================== 3 4Backward Compatibility Notes 5---------------------------- 6 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. 10 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. 16 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".. 19 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. 25 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. 31 32 33Updates since v2.19 34------------------- 35 36UI, Workflows & Features 37 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. 43 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. 47 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. 52 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. 56 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). 61 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). 66 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. 72 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". 75 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. 80 81 * The minimum version of Windows supported by Windows port of Git is 82 now set to Vista. 83 84 * The completion script (in contrib/) learned to complete a handful of 85 options "git stash list" command takes. 86 87 * The completion script (in contrib/) learned that "git fetch 88 --multiple" only takes remote names as arguments and no refspecs. 89 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). 93 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. 100 101 * 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. 105 106 * 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. 115 116 * "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. 120 121 * The documentation of "git gc" has been updated to mention that it 122 is no longer limited to "pruning away crufts" but also updates 123 ancillary files like commit-graph as a part of repository 124 optimization. 125 126 * "git p4 unshelve" improvements. 127 128 * 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). 131 132 * The "rev-list --filter" feature learned to exclude all trees via 133 "tree:0" filter. 134 135 * "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. 139 140 * Developer builds now uses -Wunused-function compilation option. 141 142 * One of our CI tests to run with "unusual/experimental/random" 143 settings now also uses commit-graph and midx. 144 145 * "git mergetool" learned to take the "--[no-]gui" option, just like 146 "git difftool" does. 147 148 * "git rebase -i" learned a new insn, 'break', that the user can 149 insert in the to-do list. Upon hitting it, the command returns 150 control back to the user. 151 152 * New "--pretty=format:" placeholders %GF and %GP that show the GPG 153 key fingerprints have been invented. 154 155 * On platforms with recent cURL library, http.sslBackend configuration 156 variable can be used to choose a different SSL backend at runtime. 157 The Windows port uses this mechanism to switch between OpenSSL and 158 Secure Channel while talking over the HTTPS protocol. 159 160 * "git send-email" learned to disable SMTP authentication via the 161 "--smtp-auth=none" option, even when the smtp username is given 162 (which turns the authentication on by default). 163 164 * A fourth class of configuration files (in addition to the 165 traditional "system wide", "per user in the $HOME directory" and 166 "per repository in the $GIT_DIR/config") has been introduced so 167 that different worktrees that share the same repository (hence the 168 same $GIT_DIR/config file) can use different customization. 169 170 * A pattern with '**' that does not have a slash on either side used 171 to be an invalid one, but the code now treats such double-asterisks 172 the same way as two normal asterisks that happen to be adjacent to 173 each other. 174 (merge e5bbe09e88 nd/wildmatch-double-asterisk later to maint). 175 176 * The "--no-patch" option, which can be used to get a high-level 177 overview without the actual line-by-line patch difference shown, of 178 the "range-diff" command was earlier broken, which has been 179 corrected. 180 181 * The recently merged "rebase in C" has an escape hatch to use the 182 scripted version when necessary, but it hasn't been documented, 183 which has been corrected. 184 185 186Performance, Internal Implementation, Development Support etc. 187 188 * 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. 192 193 * "git submodule update" is getting rewritten piece-by-piece into C. 194 195 * The code for computing history reachability has been shuffled, 196 obtained a bunch of new tests to cover them, and then being 197 improved. 198 199 * 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. 206 207 * 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. 212 213 * 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. 216 217 * 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. 221 222 * Split Documentation/config.txt for easier maintenance. 223 (merge 6014363f0b nd/config-split later to maint). 224 225 * Test helper binaries clean-up. 226 (merge c9a1f4161f nd/test-tool later to maint). 227 228 * 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). 231 232 * Update fsck.skipList implementation and documentation. 233 (merge 371a655074 ab/fsck-skiplist later to maint). 234 235 * An alias that expands to another alias has so far been forbidden, 236 but now it is allowed to create such an alias. 237 238 * Various test scripts have been updated for style and also correct 239 handling of exit status of various commands. 240 241 * "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. 247 248 * 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). 252 253 * 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). 256 257 * 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). 260 261 * 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. 263 264 * 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. 267 268 * 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. 271 272 * 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. 279 280 * 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). 283 284 * 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). 288 289 * An experiment to fuzz test a few areas, hopefully we can gain more 290 coverage to various areas. 291 292 * More codepaths are moving away from hardcoded hash sizes. 293 294 * The way the Windows port figures out the current directory has been 295 improved. 296 297 * The way DLLs are loaded on the Windows port has been improved. 298 299 * Some tests have been reorganized and renamed; "ls t/" now gives a 300 better overview of what is tested for these scripts than before. 301 302 * "git rebase" and "git rebase -i" have been reimplemented in C. 303 304 * Windows port learned to use nano-second resolution file timestamps. 305 306 * The overly large Documentation/config.txt file have been split into 307 million little pieces. This potentially allows each individual piece 308 included into the manual page of the command it affects more easily. 309 310 * Replace three string-list instances used as look-up tables in "git 311 fetch" with hashmaps. 312 313 * 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". 315 316 * 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. 319 320 * The history traversal used to implement the tag-following has been 321 optimized by introducing a new helper. 322 323 * 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. 326 327 * 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. 331 332 * "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. 336 337 * 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. 340 341 * The support for format-patch (and send-email) by the command-line 342 completion script (in contrib/) has been simplified a bit. 343 344 * The revision walker machinery learned to take advantage of the 345 commit generation numbers stored in the commit-graph file. 346 347 * The codebase has been cleaned up to reduce "#ifndef NO_PTHREADS". 348 349 * 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. 351 352 * Various functions have been audited for "-Wunused-parameter" warnings 353 and bugs in them got fixed. 354 355 * A sanity check for start-up sequence has been added in the config 356 API codepath. 357 358 * The build procedure to link for fuzzing test has been made 359 customizable with a new Makefile variable. 360 361 * 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. 364 365 * 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). 369 370 * "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. 374 375 * 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. 379 380 * Code preparation to replace ulong vars with size_t vars where 381 appropriate continues. 382 383 * The "test installed Git" mode of our test suite has been updated to 384 work better. 385 386 * 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. 389 390 391Fixes since v2.19 392----------------- 393 394 * "git interpret-trailers" and its underlying machinery had a buggy 395 code that attempted to ignore patch text after commit log message, 396 which triggered in various codepaths that will always get the log 397 message alone and never get such an input. 398 (merge 66e83d9b41 jk/trailer-fixes later to maint). 399 400 * Malformed or crafted data in packstream can make our code attempt 401 to read or write past the allocated buffer and abort, instead of 402 reporting an error, which has been fixed. 403 404 * "git rebase -i" did not clear the state files correctly when a run 405 of "squash/fixup" is aborted and then the user manually amended the 406 commit instead, which has been corrected. 407 (merge 10d2f35436 js/rebase-i-autosquash-fix later to maint). 408 409 * When fsmonitor is in use, after operation on submodules updates 410 .gitmodules, we lost track of the fact that we did so and relied on 411 stale fsmonitor data. 412 (merge 43f1180814 bp/mv-submodules-with-fsmonitor later to maint). 413 414 * Fix for a long-standing bug that leaves the index file corrupt when 415 it shrinks during a partial commit. 416 (merge 6c003d6ffb jk/reopen-tempfile-truncate later to maint). 417 418 * Further fix for O_APPEND emulation on Windows 419 (merge eeaf7ddac7 js/mingw-o-append later to maint). 420 421 * A corner case bugfix in "git rerere" code. 422 (merge ad2bf0d9b4 en/rerere-multi-stage-1-fix later to maint). 423 424 * "git add ':(attr:foo)'" is not supported and is supposed to be 425 rejected while the command line arguments are parsed, but we fail 426 to reject such a command line upfront. 427 (merge 84d938b732 nd/attr-pathspec-fix later to maint). 428 429 * Recent update broke the reachability algorithm when refs (e.g. 430 tags) that point at objects that are not commit were involved, 431 which has been fixed. 432 433 * "git rebase" etc. in Git 2.19 fails to abort when given an empty 434 commit log message as result of editing, which has been corrected. 435 (merge a3ec9eaf38 en/sequencer-empty-edit-result-aborts later to maint). 436 437 * The code to backfill objects in lazily cloned repository did not 438 work correctly, which has been corrected. 439 (merge e68302011c jt/lazy-object-fetch-fix later to maint). 440 441 * Update error messages given by "git remote" and make them consistent. 442 (merge 5025425dff ms/remote-error-message-update later to maint). 443 444 * "git update-ref" learned to make both "--no-deref" and "--stdin" 445 work at the same time. 446 (merge d345e9fbe7 en/update-ref-no-deref-stdin later to maint). 447 448 * Recently added "range-diff" had a corner-case bug to cause it 449 segfault, which has been corrected. 450 (merge e467a90c7a tg/range-diff-corner-case-fix later to maint). 451 452 * The recently introduced commit-graph auxiliary data is incompatible 453 with mechanisms such as replace & grafts that "breaks" immutable 454 nature of the object reference relationship. Disable optimizations 455 based on its use (and updating existing commit-graph) when these 456 incompatible features are in use in the repository. 457 (merge 829a321569 ds/commit-graph-with-grafts later to maint). 458 459 * The mailmap file update. 460 (merge 255eb03edf jn/mailmap-update later to maint). 461 462 * The code in "git status" sometimes hit an assertion failure. This 463 was caused by a structure that was reused without cleaning the data 464 used for the first run, which has been corrected. 465 (merge 3e73cc62c0 en/status-multiple-renames-to-the-same-target-fix later to maint). 466 467 * "git fetch $repo $object" in a partial clone did not correctly 468 fetch the asked-for object that is referenced by an object in 469 promisor packfile, which has been fixed. 470 471 * A corner-case bugfix. 472 (merge c5cbb27cb5 sm/show-superproject-while-conflicted later to maint). 473 474 * Various fixes to "diff --color-moved-ws". 475 476 * A partial clone that is configured to lazily fetch missing objects 477 will on-demand issue a "git fetch" request to the originating 478 repository to fill not-yet-obtained objects. The request has been 479 optimized for requesting a tree object (and not the leaf blob 480 objects contained in it) by telling the originating repository that 481 no blobs are needed. 482 (merge 4c7f9567ea jt/non-blob-lazy-fetch later to maint). 483 484 * The codepath to support the experimental split-index mode had 485 remaining "racily clean" issues fixed. 486 (merge 4c490f3d32 sg/split-index-racefix later to maint). 487 488 * "git log --graph" showing an octopus merge sometimes miscounted the 489 number of display columns it is consuming to show the merge and its 490 parent commits, which has been corrected. 491 (merge 04005834ed np/log-graph-octopus-fix later to maint). 492 493 * "git range-diff" did not work well when the compared ranges had 494 changes in submodules and the "--submodule=log" was used. 495 496 * The implementation of run_command() API on the UNIX platforms had a 497 bug that caused a command not on $PATH to be found in the current 498 directory. 499 (merge f67b980771 jk/run-command-notdot later to maint). 500 501 * A mutex used in "git pack-objects" were not correctly initialized 502 and this caused "git repack" to dump core on Windows. 503 (merge 34204c8166 js/pack-objects-mutex-init-fix later to maint). 504 505 * Under certain circumstances, "git diff D:/a/b/c D:/a/b/d" on 506 Windows would strip initial parts from the paths because they 507 were not recognized as absolute, which has been corrected. 508 (merge ffd04e92e2 js/diff-notice-has-drive-prefix later to maint). 509 510 * The receive.denyCurrentBranch=updateInstead codepath kicked in even 511 when the push should have been rejected due to other reasons, such 512 as it does not fast-forward or the update-hook rejects it, which 513 has been corrected. 514 (merge b072a25fad jc/receive-deny-current-branch-fix later to maint). 515 516 * The logic to determine the archive type "git archive" uses did not 517 correctly kick in for "git archive --remote", which has been 518 corrected. 519 520 * "git repack" in a shallow clone did not correctly update the 521 shallow points in the repository, leading to a repository that 522 does not pass fsck. 523 (merge 5dcfbf564c js/shallow-and-fetch-prune later to maint). 524 525 * Some codepaths failed to form a proper URL when .gitmodules record 526 the URL to a submodule repository as relative to the repository of 527 superproject, which has been corrected. 528 (merge e0a862fdaf sb/submodule-url-to-absolute later to maint). 529 530 * "git fetch" over protocol v2 into a shallow repository failed to 531 fetch full history behind a new tip of history that was diverged 532 before the cut-off point of the history that was previously fetched 533 shallowly. 534 535 * The command line completion machinery (in contrib/) has been 536 updated to allow the completion script to tweak the list of options 537 that are reported by the parse-options machinery correctly. 538 (merge 276b49ff34 nd/completion-negation later to maint). 539 540 * Operations on promisor objects make sense in the context of only a 541 small subset of the commands that internally use the revisions 542 machinery, but the "--exclude-promisor-objects" option were taken 543 and led to nonsense results by commands like "log", to which it 544 didn't make much sense. This has been corrected. 545 (merge 669b1d2aae md/exclude-promisor-objects-fix later to maint). 546 547 * The "container" mode of TravisCI is going away. Our .travis.yml 548 file is getting prepared for the transition. 549 (merge 32ee384be8 ss/travis-ci-force-vm-mode later to maint). 550 551 * Our test scripts can now take the '-V' option as a synonym for the 552 '--verbose-log' option. 553 (merge a5f52c6dab sg/test-verbose-log later to maint). 554 555 * 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). 558 559 * "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). 563 564 * Additional comment on a tricky piece of code to help developers. 565 (merge 0afbe3e806 jk/stream-pack-non-delta-clarification later to maint). 566 567 * 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). 570 571 * 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). 575 576 * "git fetch" was a bit loose in parsing responses from the other side 577 when talking over the protocol v2. 578 579 * "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). 585 586 * "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). 590 591 * 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). 597 598 * 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). 601 602 * "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). 606 607 * "git rebase --autostash" did not correctly re-attach the HEAD at times. 608 609 * "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). 612 613 * 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). 618 619 * The URL to an MSDN page in a comment has been updated. 620 (merge 2ef2ae2917 js/mingw-msdn-url later to maint). 621 622 * "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. 625 626 * 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). 632 633 * "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). 636 637 * 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). 641 642 * Code cleanup, docfix, build fix, etc. 643 (merge 96a7501aad ts/doc-build-manpage-xsl-quietly later to maint). 644 (merge b9b07efdb2 tg/conflict-marker-size later to maint). 645 (merge fa0aeea770 sg/doc-trace-appends later to maint). 646 (merge d64324cb60 tb/void-check-attr later to maint). 647 (merge c3b9bc94b9 en/double-semicolon-fix later to maint). 648 (merge 79336116f5 sg/t3701-tighten-trace later to maint). 649 (merge 801fa63a90 jk/dev-build-format-security later to maint). 650 (merge 0597dd62ba sb/string-list-remove-unused later to maint). 651 (merge db2d36fad8 bw/protocol-v2 later to maint). 652 (merge 456d7cd3a9 sg/split-index-test later to maint). 653 (merge 7b6057c852 tq/refs-internal-comment-fix later to maint). 654 (merge 29e8dc50ad tg/t5551-with-curl-7.61.1 later to maint). 655 (merge 55f6bce2c9 fe/doc-updates later to maint). 656 (merge 7987d2232d jk/check-everything-connected-is-long-gone later to maint). 657 (merge 4ba3c9be47 dz/credential-doc-url-matching-rules later to maint). 658 (merge 4c399442f7 ma/commit-graph-docs later to maint). 659 (merge fc0503b04e ma/t1400-undebug-test later to maint). 660 (merge e56b53553a nd/packobjectshook-doc-fix later to maint). 661 (merge c56170a0c4 ma/mailing-list-address-in-git-help later to maint). 662 (merge 6e8fc70fce rs/sequencer-oidset-insert-avoids-dups later to maint). 663 (merge ad0b8f9575 mw/doc-typofixes later to maint). 664 (merge d9f079ad1a jc/how-to-document-api later to maint). 665 (merge b1492bf315 ma/t7005-bash-workaround later to maint). 666 (merge ac1f98a0df du/rev-parse-is-plumbing later to maint). 667 (merge ca8ed443a5 mm/doc-no-dashed-git later to maint). 668 (merge ce366a8144 du/get-tar-commit-id-is-plumbing later to maint). 669 (merge 61018fe9e0 du/cherry-is-plumbing later to maint). 670 (merge c7e5fe79b9 sb/strbuf-h-update later to maint). 671 (merge 8d2008196b tq/branch-create-wo-branch-get later to maint). 672 (merge 2e3c894f4b tq/branch-style-fix later to maint). 673 (merge c5d844af9c sg/doc-show-branch-typofix later to maint). 674 (merge 081d91618b ah/doc-updates later to maint). 675 (merge b84c783882 jc/cocci-preincr later to maint). 676 (merge 5e495f8122 uk/merge-subtree-doc-update later to maint). 677 (merge aaaa881822 jk/uploadpack-packobjectshook-fix later to maint). 678 (merge 3063477445 tb/char-may-be-unsigned later to maint). 679 (merge 8c64bc9420 sg/test-rebase-editor-fix later to maint). 680 (merge 71571cd7d6 ma/sequencer-do-reset-saner-loop-termination later to maint). 681 (merge 9a4cb8781e cb/notes-freeing-always-null-fix later to maint).
