1 Git 2.26 Release Notes
2 ======================
4 Updates since v2.25
5 -------------------
7 UI, Workflows & Features
9 * Sample credential helper for using .netrc has been updated to work
10 out of the box.
12 * gpg.minTrustLevel configuration variable has been introduced to
13 tell various signature verification codepaths the required minimum
14 trust level.
16 * The command line completion (in contrib/) learned to complete
17 subcommands and arguments to "git worktree".
19 * Disambiguation logic to tell revisions and pathspec apart has been
20 tweaked so that backslash-escaped glob special characters do not
21 count in the "wildcards are pathspec" rule.
23 * One effect of specifying where the GIT_DIR is (either with the
24 environment variable, or with the "git --git-dir=<where> cmd"
25 option) is to disable the repository discovery. This has been
26 placed a bit more stress in the documentation, as new users often
27 get confused.
29 * Two help messages given when "git add" notices the user gave it
30 nothing to add have been updated to use advise() API.
32 * A new version of fsmonitor-watchman hook has been introduced, to
33 avoid races.
36 Performance, Internal Implementation, Development Support etc.
38 * Tell .editorconfig that in this project, *.txt files are indented
39 with tabs.
41 * The test-lint machinery knew to check "VAR=VAL shell_function"
42 construct, but did not check "VAR= shell_funciton", which has been
43 corrected.
45 * Replace "git config --bool" calls with "git config --type=bool" in
46 sample templates.
48 * The effort to move "git-add--interactive" to C continues.
50 * Improve error message generation for "git submodule add".
52 * Preparation of test scripts for the day when the object names will
53 use SHA-256 continues.
55 * Warn programmers about pretend_object_file() that allows the code
56 to tentatively use in-core objects.
58 * The way "git pack-objects" reuses objects stored in existing pack
59 to generate its result has been improved.
61 * The transport protocol version 2 becomes the default one.
63 * Traditionally, we avoided threaded grep while searching in objects
64 (as opposed to files in the working tree) as accesses to the object
65 layer is not thread-safe. This limitation is getting lifted.
67 * "git rebase -i" (and friends) used to unnecessarily check out the
68 tip of the branch to be rebased, which has been corrected.
70 * A low-level API function get_oid(), that accepts various ways to
71 name an object, used to issue end-user facing error messages
72 without l10n, which has been updated to be translatable.
74 * Unneeded connectivity check is now disabled in a partial clone when
75 fetching into it.
77 * Some rough edges in the sparse-checkout feature, especially around
78 the cone mode, have been cleaned up.
80 * The diff-* plumbing family of subcommands now pay attention to the
81 diff.wsErrorHighlight configuration, which has been ignored before;
82 this allows "git add -p" to also show the whitespace problems to
83 the end user.
85 * Some codepaths were given a repository instance as a parameter to
86 work in the repository, but passed the_repository instance to its
87 callees, which has been cleaned up (somewhat).
90 Fixes since v2.25
91 -----------------
93 * "git commit" gives output similar to "git status" when there is
94 nothing to commit, but without honoring the advise.statusHints
95 configuration variable, which has been corrected.
96 (merge 5c4f55f1f6 hw/commit-advise-while-rejecting later to maint).
98 * has_object_file() said "no" given an object registered to the
99 system via pretend_object_file(), making it inconsistent with
100 read_object_file(), causing lazy fetch to attempt fetching an
101 empty tree from promisor remotes.
102 (merge 9c8a294a1a jt/sha1-file-remove-oi-skip-cached later to maint).
104 * Complete an update to tutorial that encourages "git switch" over
105 "git checkout" that was done only half-way.
106 (merge 1a7e454dd6 hw/tutorial-favor-switch-over-checkout later to maint).
108 * C pedantry ;-) fix.
109 (merge 63ab08fb99 bc/run-command-nullness-after-free-fix later to maint).
111 * The code that tries to skip over the entries for the paths in a
112 single directory using the cache-tree was not careful enough
113 against corrupt index file.
114 (merge 573117dfa5 es/unpack-trees-oob-fix later to maint).
116 * Reduce unnecessary round-trip when running "ls-remote" over the
117 stateless RPC mechanism.
118 (merge 4d8cab95cc jk/no-flush-upon-disconnecting-slrpc-transport later to maint).
120 * "git restore --staged" did not correctly update the cache-tree
121 structure, resulting in bogus trees to be written afterwards, which
122 has been corrected.
123 (merge e701bab3e9 nd/switch-and-restore later to maint).
125 * The code recently added to move to the entry beyond the ones in the
126 same directory in the index in the sparse-cone mode did not count
127 the number of entries to skip over incorrectly, which has been
128 corrected.
129 (merge 7210ca4ee5 ds/sparse-cone later to maint).
131 * Rendering by "git log --graph" of ancestry lines leading to a merge
132 commit were made suboptimal to waste vertical space a bit with a
133 recent update, which has been corrected.
134 (merge c958d3bd0a ds/graph-horizontal-edges later to maint).
136 * Work around test breakages caused by custom regex engine used in
137 libasan, when address sanitizer is used with more recent versions
138 of gcc and clang.
139 (merge f65d07fffa jk/asan-build-fix later to maint).
141 * Minor bugfixes to "git add -i" that has recently been rewritten in C.
142 (merge 849e43cc18 js/builtin-add-i-cmds later to maint).
144 * "git fetch --refmap=" option has got a better documentation.
145 (merge b40a50264a ds/refmap-doc later to maint).
147 * "git checkout X" did not correctly fail when X is not a local
148 branch but could name more than one remote-tracking branches
149 (i.e. to be dwimmed as the starting point to create a corresponding
150 local branch), which has been corrected.
151 (merge fa74180d08 am/checkout-file-and-ref-ref-ambiguity later to maint).
153 * Corner case bugs in "git clean" that stems from a (necessarily for
154 performance reasons) awkward calling convention in the directory
155 enumeration API has been corrected.
156 (merge 0cbb60574e en/fill-directory-fixes-more later to maint).
158 * A fetch that is told to recursively fetch updates in submodules
159 inevitably produces reams of output, and it becomes hard to spot
160 error messages. The command has been taught to enumerate
161 submodules that had errors at the end of the operation.
162 (merge 0222540827 es/fetch-show-failed-submodules-atend later to maint).
164 * The "--recurse-submodules" option of various subcommands did not
165 work well when run in an alternate worktree, which has been
166 corrected.
167 (merge a9472afb63 pb/recurse-submodule-in-worktree-fix later to maint).
169 * Futureproofing a test not to depend on the current implementation
170 detail.
171 (merge b54128bb0b jt/t5616-robustify later to maint).
173 * Running "git rm" on a submodule failed unnecessarily when
174 .gitmodules is only cache-dirty, which has been corrected.
175 (merge 7edee32985 dt/submodule-rm-with-stale-cache later to maint).
177 * C pedantry ;-) fix.
178 (merge cf82bff73f jk/clang-sanitizer-fixes later to maint).
180 * "git grep --no-index" should not get affected by the contents of
181 the .gitmodules file but when "--recurse-submodules" is given or
182 the "submodule.recurse" variable is set, it did. Now these
183 settings are ignored in the "--no-index" mode.
184 (merge c56c48dd07 pb/do-not-recurse-grep-no-index later to maint).
186 * Technical details of the bundle format has been documented.
187 (merge 7378ec90e1 ms/doc-bundle-format later to maint).
189 * Unhelpful warning messages during documentation build have been squelched.
190 (merge 30183894ea js/ci-squelch-doc-warning later to maint).
192 * "git rebase -i" identifies existing commits in its todo file with
193 their abbreviated object name, which could become ambigous as it
194 goes to create new commits, and has a mechanism to avoid ambiguity
195 in the main part of its execution. A few other cases however were
196 not covered by the protection against ambiguity, which has been
197 corrected.
198 (merge 26027625dd js/rebase-i-with-colliding-hash later to maint).
200 * Allow the rebase.missingCommitsCheck configuration to kick in when
201 "rebase --edit-todo" and "rebase --continue" restarts the procedure.
202 (merge 5a5445d878 ag/edit-todo-drop-check later to maint).
204 * The way "git submodule status" reports an initialized but not yet
205 populated submodule has not been reimplemented correctly when a
206 part of the "git submodule" command was rewritten in C, which has
207 been corrected.
208 (merge f38c92452d pk/status-of-uncloned-submodule later to maint).
210 * The code to automatically shrink the fan-out in the notes tree had
211 an off-by-one bug, which has been killed.
212 (merge dbc27477ff jh/notes-fanout-fix later to maint).
214 * The index-pack code now diagnoses a bad input packstream that
215 records the same object twice when it is used as delta base; the
216 code used to declare a software bug when encountering such an
217 input, but it is an input error.
218 (merge a21781011f jk/index-pack-dupfix later to maint).
220 * The code to compute the commit-graph has been taught to use a more
221 robust way to tell if two object directories refer to the same
222 thing.
223 (merge a7df60cac8 tb/commit-graph-object-dir later to maint).
225 * Other code cleanup, docfix, build fix, etc.
226 (merge 26f924d50e en/simplify-check-updates-in-unpack-trees later to maint).
227 (merge 065027ee1a en/string-list-can-be-custom-sorted later to maint).
228 (merge d0d0a357a1 am/update-pathspec-f-f-tests later to maint).
229 (merge f94f7bd00d am/test-pathspec-f-f-error-cases later to maint).
