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 50Performance, Internal Implementation, Development Support etc. 51 52 * Update supporting parts of "git rebase" to remove code that should 53 no longer be used. 54 55 * Developer support to emulate unsatisfied prerequisites in tests to 56 ensure that the remainer of the tests still succeeds when tests 57 with prerequisites are skipped. 58 59 * "git update-server-info" learned not to rewrite the file with the 60 same contents. 61 62 * The way of specifying the path to find dynamic libraries at runtime 63 has been simplified. The old default to pass -R/path/to/dir has been 64 replaced with the new default to pass -Wl,-rpath,/path/to/dir, 65 which is the more recent GCC uses. Those who need to build with an 66 old GCC can still use "CC_LD_DYNPATH=-R" 67 68 * Prepare use of reachability index in topological walker that works 69 on a range (A..B). 70 71 * A new tutorial targetting specifically aspiring git-core 72 developers has been added. 73 74 75 76Fixes since v2.22 77----------------- 78 79 * A relative pathname given to "git init --template=<path> <repo>" 80 ought to be relative to the directory "git init" gets invoked in, 81 but it instead was made relative to the repository, which has been 82 corrected. 83 (merge e1df7fe43f nd/init-relative-template-fix later to maint). 84 85 * "git worktree add" used to fail when another worktree connected to 86 the same repository was corrupt, which has been corrected. 87 (merge 105df73e71 nd/corrupt-worktrees later to maint). 88 89 * The ownership rule for the file descriptor to fast-import remote 90 backend was mixed up, leading to unrelated file descriptor getting 91 closed, which has been fixed. 92 (merge 3203566a71 mh/import-transport-fd-fix later to maint). 93 94 * A "merge -c" instruction during "git rebase --rebase-merges" should 95 give the user a chance to edit the log message, even when there is 96 otherwise no need to create a new merge and replace the existing 97 one (i.e. fast-forward instead), but did not. Which has been 98 corrected. 99 100 * Code cleanup and futureproof. 101 (merge 31f5256c82 ds/object-info-for-prefetch-fix later to maint). 102 103 * More parameter validation. 104 (merge de99eb0c24 es/grep-require-name-when-needed later to maint). 105 106 * "git update-server-info" used to leave stale packfiles in its 107 output, which has been corrected. 108 (merge e941c48d49 ew/server-info-remove-crufts later to maint). 109 110 * The server side support for "git fetch" used to show incorrect 111 value for the HEAD symbolic ref when the namespace feature is in 112 use, which has been corrected. 113 (merge 533e088250 jk/HEAD-symref-in-xfer-namespaces later to maint). 114 115 * "git am -i --resolved" segfaulted after trying to see a commit as 116 if it were a tree, which has been corrected. 117 (merge 7663e438c5 jk/am-i-resolved-fix later to maint). 118 119 * "git bundle verify" needs to see if prerequisite objects exist in 120 the receiving repository, but the command did not check if we are 121 in a repository upfront, which has been corrected. 122 (merge 3bbbe467f2 js/bundle-verify-require-object-store later to maint). 123 124 * "git merge --squash" is designed to update the working tree and the 125 index without creating the commit, and this cannot be countermanded 126 by adding the "--commit" option; the command now refuses to work 127 when both options are given. 128 (merge 1d14d0c994 vv/merge-squash-with-explicit-commit later to maint). 129 130 * The data collected by fsmonitor was not properly written back to 131 the on-disk index file, breaking t7519 tests occasionally, which 132 has been corrected. 133 (merge b5a8169752 js/fsmonitor-unflake later to maint). 134 135 * Update to Unicode 12.1 width table. 136 (merge 5817f9caa3 bb/unicode-12.1-reiwa later to maint). 137 138 * The command line to invoke a "git cat-file" command from inside 139 "git p4" was not properly quoted to protect a caret and running a 140 broken command on Windows, which has been corrected. 141 (merge c3f2358de3 mm/p4-unshelve-windows-fix later to maint). 142 143 * "git request-pull" learned to warn when the ref we ask them to pull 144 from in the local repository and in the published repository are 145 different. 146 (merge 0454220d66 pb/request-pull-verify-remote-ref later to maint). 147 148 * When creating a partial clone, the object filtering criteria is 149 recorded for the origin of the clone, but this incorrectly used a 150 hardcoded name "origin" to name that remote; it has been corrected 151 to honor the "--origin <name>" option. 152 (merge 1c4a9f9114 xl/record-partial-clone-origin later to maint). 153 154 * "git fetch" into a lazy clone forgot to fetch base objects that are 155 necessary to complete delta in a thin packfile, which has been 156 corrected. 157 (merge 810e19322d jt/partial-clone-missing-ref-delta-base later to maint). 158 159 * The filter_data used in the list-objects-filter (which manages a 160 lazily sparse clone repository) did not use the dynamic array API 161 correctly---'nr' is supposed to point at one past the last element 162 of the array in use. This has been corrected. 163 (merge 7140600e2e md/list-objects-filter-memfix later to maint). 164 165 * The description about slashes in gitignore patterns (used to 166 indicate things like "anchored to this level only" and "only 167 matches directories") has been revamped. 168 (merge 1a58bad014 an/ignore-doc-update later to maint). 169 170 * The URL decoding code has been updated to avoid going past the end 171 of the string while parsing %-<hex>-<hex> sequence. 172 (merge d37dc239a4 md/url-parse-harden later to maint). 173 174 * The list of for-each like macros used by clang-format has been 175 updated. 176 (merge fc7e03aace mo/clang-format-for-each-update later to maint). 177 178 * Other code cleanup, docfix, build fix, etc. 179 (merge f547101b26 es/git-debugger-doc later to maint). 180 (merge 7877ac3d7b js/bisect-helper-check-get-oid-return-value later to maint). 181 (merge 0108f47eb3 sw/git-p4-unshelve-branched-files later to maint). 182 (merge 9df8f734fd cm/send-email-document-req-modules later to maint). 183 (merge afc3bf6eb1 ab/hash-object-doc later to maint).
