1Git 2.23 Release Notes 2====================== 3 4Updates since v2.22 5------------------- 6 7Backward compatibility note 8 9 * The "--base" option of "format-patch" computed the patch-ids for 10 prerequisite patches in an unstable way, which has been updated to 11 compute in a way that is compatible with "git patch-id --stable". 12 13 14UI, Workflows & Features 15 16 * The "git fast-export/import" pair has been taught to handle commits 17 with log messages in encoding other than UTF-8 better. 18 19 * In recent versions of Git, per-worktree refs are exposed in 20 refs/worktrees/<wtname>/ hierarchy, which means that worktree names 21 must be a valid refname component. The code now sanitizes the names 22 given to worktrees, to make sure these refs are well-formed. 23 24 * "git merge" learned "--quit" option that cleans up the in-progress 25 merge while leaving the working tree and the index still in a mess. 26 27 * "git format-patch" learns a configuration to set the default for 28 its --notes=<ref> option. 29 30 * The code to show args with potential typo that cannot be 31 interpreted as a commit-ish has been improved. 32 33 * "git clone --recurse-submodules" learned to set up the submodules 34 to ignore commit object names recorded in the superproject gitlink 35 and instead use the commits that happen to be at the tip of the 36 remote-tracking branches from the get-go, by passing the new 37 "--remote-submodules" option. 38 39 * The pattern "git diff/grep" use to extract funcname and words 40 boundary for Matlab has been extend to cover Octave, which is more 41 or less equivalent. 42 43 * "git help git" was hard to discover (well, at least for some 44 people). 45 46 * The pattern "git diff/grep" use to extract funcname and words 47 boundary for Rust has been added. 48 49 * "git status" can be told a non-standard default value for the 50 "--[no-]ahead-behind" option with a new configuration variable 51 status.aheadBehind. 52 53 * "git fetch" and "git pull" reports when a fetch results in 54 non-fast-forward updates to let the user notice unusual situation. 55 The commands learned "--no-shown-forced-updates" option to disable 56 this safety feature. 57 58 * Two new commands "git switch" and "git restore" are introduced to 59 split "checking out a branch to work on advancing its history" and 60 "checking out paths out of the index and/or a tree-ish to work on 61 advancing the current history" out of the single "git checkout" 62 command. 63 64 * "git branch --list" learned to always output the detached HEAD as 65 the first item (when the HEAD is detached, of course), regardless 66 of the locale. 67 68 * The conditional inclusion mechanism learned to base the choice on 69 the branch the HEAD currently is on. 70 71 * "git rev-list --objects" learned with "--no-object-names" option to 72 squelch the path to the object that is used as a grouping hint for 73 pack-objects. 74 75 * A new tag.gpgSign configuration variable turns "git tag -a" into 76 "git tag -s". 77 78 79Performance, Internal Implementation, Development Support etc. 80 81 * Update supporting parts of "git rebase" to remove code that should 82 no longer be used. 83 84 * Developer support to emulate unsatisfied prerequisites in tests to 85 ensure that the remainer of the tests still succeeds when tests 86 with prerequisites are skipped. 87 88 * "git update-server-info" learned not to rewrite the file with the 89 same contents. 90 91 * The way of specifying the path to find dynamic libraries at runtime 92 has been simplified. The old default to pass -R/path/to/dir has been 93 replaced with the new default to pass -Wl,-rpath,/path/to/dir, 94 which is the more recent GCC uses. Those who need to build with an 95 old GCC can still use "CC_LD_DYNPATH=-R" 96 97 * Prepare use of reachability index in topological walker that works 98 on a range (A..B). 99 100 * A new tutorial targetting specifically aspiring git-core 101 developers has been added. 102 103 * Auto-detect how to tell HP-UX aCC where to use dynamically linked 104 libraries from at runtime. 105 106 * "git mergetool" and its tests now spawn fewer subprocesses. 107 108 * Dev support update to help tracing out tests. 109 110 * Support to build with MSVC has been updated. 111 112 * "git fetch" that grabs from a group of remotes learned to run the 113 auto-gc only once at the very end. 114 115 116Fixes since v2.22 117----------------- 118 119 * A relative pathname given to "git init --template=<path> <repo>" 120 ought to be relative to the directory "git init" gets invoked in, 121 but it instead was made relative to the repository, which has been 122 corrected. 123 (merge e1df7fe43f nd/init-relative-template-fix later to maint). 124 125 * "git worktree add" used to fail when another worktree connected to 126 the same repository was corrupt, which has been corrected. 127 (merge 105df73e71 nd/corrupt-worktrees later to maint). 128 129 * The ownership rule for the file descriptor to fast-import remote 130 backend was mixed up, leading to unrelated file descriptor getting 131 closed, which has been fixed. 132 (merge 3203566a71 mh/import-transport-fd-fix later to maint). 133 134 * A "merge -c" instruction during "git rebase --rebase-merges" should 135 give the user a chance to edit the log message, even when there is 136 otherwise no need to create a new merge and replace the existing 137 one (i.e. fast-forward instead), but did not. Which has been 138 corrected. 139 140 * Code cleanup and futureproof. 141 (merge 31f5256c82 ds/object-info-for-prefetch-fix later to maint). 142 143 * More parameter validation. 144 (merge de99eb0c24 es/grep-require-name-when-needed later to maint). 145 146 * "git update-server-info" used to leave stale packfiles in its 147 output, which has been corrected. 148 (merge e941c48d49 ew/server-info-remove-crufts later to maint). 149 150 * The server side support for "git fetch" used to show incorrect 151 value for the HEAD symbolic ref when the namespace feature is in 152 use, which has been corrected. 153 (merge 533e088250 jk/HEAD-symref-in-xfer-namespaces later to maint). 154 155 * "git am -i --resolved" segfaulted after trying to see a commit as 156 if it were a tree, which has been corrected. 157 (merge 7663e438c5 jk/am-i-resolved-fix later to maint). 158 159 * "git bundle verify" needs to see if prerequisite objects exist in 160 the receiving repository, but the command did not check if we are 161 in a repository upfront, which has been corrected. 162 (merge 3bbbe467f2 js/bundle-verify-require-object-store later to maint). 163 164 * "git merge --squash" is designed to update the working tree and the 165 index without creating the commit, and this cannot be countermanded 166 by adding the "--commit" option; the command now refuses to work 167 when both options are given. 168 (merge 1d14d0c994 vv/merge-squash-with-explicit-commit later to maint). 169 170 * The data collected by fsmonitor was not properly written back to 171 the on-disk index file, breaking t7519 tests occasionally, which 172 has been corrected. 173 (merge b5a8169752 js/fsmonitor-unflake later to maint). 174 175 * Update to Unicode 12.1 width table. 176 (merge 5817f9caa3 bb/unicode-12.1-reiwa later to maint). 177 178 * The command line to invoke a "git cat-file" command from inside 179 "git p4" was not properly quoted to protect a caret and running a 180 broken command on Windows, which has been corrected. 181 (merge c3f2358de3 mm/p4-unshelve-windows-fix later to maint). 182 183 * "git request-pull" learned to warn when the ref we ask them to pull 184 from in the local repository and in the published repository are 185 different. 186 (merge 0454220d66 pb/request-pull-verify-remote-ref later to maint). 187 188 * When creating a partial clone, the object filtering criteria is 189 recorded for the origin of the clone, but this incorrectly used a 190 hardcoded name "origin" to name that remote; it has been corrected 191 to honor the "--origin <name>" option. 192 (merge 1c4a9f9114 xl/record-partial-clone-origin later to maint). 193 194 * "git fetch" into a lazy clone forgot to fetch base objects that are 195 necessary to complete delta in a thin packfile, which has been 196 corrected. 197 (merge 810e19322d jt/partial-clone-missing-ref-delta-base later to maint). 198 199 * The filter_data used in the list-objects-filter (which manages a 200 lazily sparse clone repository) did not use the dynamic array API 201 correctly---'nr' is supposed to point at one past the last element 202 of the array in use. This has been corrected. 203 (merge 7140600e2e md/list-objects-filter-memfix later to maint). 204 205 * The description about slashes in gitignore patterns (used to 206 indicate things like "anchored to this level only" and "only 207 matches directories") has been revamped. 208 (merge 1a58bad014 an/ignore-doc-update later to maint). 209 210 * The URL decoding code has been updated to avoid going past the end 211 of the string while parsing %-<hex>-<hex> sequence. 212 (merge d37dc239a4 md/url-parse-harden later to maint). 213 214 * The list of for-each like macros used by clang-format has been 215 updated. 216 (merge fc7e03aace mo/clang-format-for-each-update later to maint). 217 218 * "git branch --list" learned to show branches that are checked out 219 in other worktrees connected to the same repository prefixed with 220 '+', similar to the way the currently checked out branch is shown 221 with '*' in front. 222 (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint). 223 224 * Code restructuring during 2.20 period broke fetching tags via 225 "import" based transports. 226 (merge f80d922355 fc/fetch-with-import-fix later to maint). 227 228 * The commit-graph file is now part of the "files that the runtime 229 may keep open file descriptors on, all of which would need to be 230 closed when done with the object store", and the file descriptor to 231 an existing commit-graph file now is closed before "gc" finalizes a 232 new instance to replace it. 233 (merge 2d511cfc0b ds/close-object-store later to maint). 234 235 * "git checkout -p" needs to selectively apply a patch in reverse, 236 which did not work well. 237 (merge 2bd69b9024 pw/add-p-recount later to maint). 238 239 * Code clean-up to avoid signed integer wraparounds during binary search. 240 (merge 568a05c5ec rs/avoid-overflow-in-midpoint-computation later to maint). 241 242 * "git interpret-trailers" always treated '#' as the comment 243 character, regardless of core.commentChar setting, which has been 244 corrected. 245 (merge 29c83fc23f jk/trailers-use-config later to maint). 246 247 * "git stash show 23" used to work, but no more after getting 248 rewritten in C; this regression has been corrected. 249 (merge 63b50c8ffe tg/stash-ref-by-index-fix later to maint). 250 251 * "git rebase --abort" used to leave refs/rewritten/ when concluding 252 "git rebase -r", which has been corrected. 253 (merge d559f502c5 pw/rebase-abort-clean-rewritten later to maint). 254 255 * An incorrect list of options was cached after command line 256 completion failed (e.g. trying to complete a command that requires 257 a repository outside one), which has been corrected. 258 (merge 69702523af nd/completion-no-cache-failure later to maint). 259 260 * The code to parse scaled numbers out of configuration files has 261 been made more robust and also easier to follow. 262 (merge 39c575c969 rs/config-unit-parsing later to maint). 263 264 * The codepath to compute delta islands used to spew progress output 265 without giving the callers any way to squelch it, which has been 266 fixed. 267 (merge bdbdf42f8a jk/delta-islands-progress-fix later to maint). 268 269 * Protocol capabilities that go over wire should never be translated, 270 but it was incorrectly marked for translation, which has been 271 corrected. The output of protocol capabilities for debugging has 272 been tweaked a bit. 273 274 * Use "Erase in Line" CSI sequence that is already used in the editor 275 support to clear cruft in the progress output. 276 (merge 5b12e3123b sg/rebase-progress later to maint). 277 278 * "git submodule foreach" did not protect command line options passed 279 to the command to be run in each submodule correctly, when the 280 "--recursive" option was in use. 281 (merge 30db18b148 ms/submodule-foreach-fix later to maint). 282 283 * Other code cleanup, docfix, build fix, etc. 284 (merge f547101b26 es/git-debugger-doc later to maint). 285 (merge 7877ac3d7b js/bisect-helper-check-get-oid-return-value later to maint). 286 (merge 0108f47eb3 sw/git-p4-unshelve-branched-files later to maint). 287 (merge 9df8f734fd cm/send-email-document-req-modules later to maint). 288 (merge afc3bf6eb1 ab/hash-object-doc later to maint). 289 (merge 1fde99cfc7 po/doc-branch later to maint). 290 (merge 459842e1c2 dl/config-alias-doc later to maint). 291 (merge 5d137fc2c7 cb/fsmonitor-intfix later to maint). 292 (merge 921d49be86 rs/copy-array later to maint). 293 (merge cc8d872e69 js/t3404-typofix later to maint). 294 (merge 729a9b558b cb/mkstemps-uint-type-fix later to maint). 295 (merge 9dae4fe79f js/gcc-8-and-9 later to maint). 296 (merge ed33bd8f30 js/t0001-case-insensitive later to maint). 297 (merge dfa880e336 jw/gitweb-sample-update later to maint). 298 (merge e532a90a9f sg/t5551-fetch-smart-error-is-translated later to maint).
