1 Git 2.23 Release Notes
2 ======================
4 Updates since v2.22
5 -------------------
7 Backward compatibility note
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".
14 UI, Workflows & Features
16 * The "git fast-export/import" pair has been taught to handle commits
17 with log messages in encoding other than UTF-8 better.
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.
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.
27 * "git format-patch" learns a configuration to set the default for
28 its --notes=<ref> option.
30 * The code to show args with potential typo that cannot be
31 interpreted as a commit-ish has been improved.
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.
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.
43 * "git help git" was hard to discover (well, at least for some
44 people).
46 * The pattern "git diff/grep" use to extract funcname and words
47 boundary for Rust has been added.
50 Performance, Internal Implementation, Development Support etc.
52 * Update supporting parts of "git rebase" to remove code that should
53 no longer be used.
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.
59 * "git update-server-info" learned not to rewrite the file with the
60 same contents.
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"
68 * Prepare use of reachability index in topological walker that works
69 on a range (A..B).
71 * A new tutorial targetting specifically aspiring git-core
72 developers has been added.
76 Fixes since v2.22
77 -----------------
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).
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).
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).
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.
100 * Code cleanup and futureproof.
101 (merge 31f5256c82 ds/object-info-for-prefetch-fix later to maint).
103 * More parameter validation.
104 (merge de99eb0c24 es/grep-require-name-when-needed later to maint).
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).
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).
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).
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).
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).
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).
135 * Update to Unicode 12.1 width table.
136 (merge 5817f9caa3 bb/unicode-12.1-reiwa later to maint).
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).
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).
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).
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).
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).
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).
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).
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).
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).
