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.
35 * "git config" learned to show in which "scope", in addition to in
36 which file, each config setting comes from.
39 Performance, Internal Implementation, Development Support etc.
41 * Tell .editorconfig that in this project, *.txt files are indented
42 with tabs.
44 * The test-lint machinery knew to check "VAR=VAL shell_function"
45 construct, but did not check "VAR= shell_funciton", which has been
46 corrected.
48 * Replace "git config --bool" calls with "git config --type=bool" in
49 sample templates.
51 * The effort to move "git-add--interactive" to C continues.
53 * Improve error message generation for "git submodule add".
55 * Preparation of test scripts for the day when the object names will
56 use SHA-256 continues.
58 * Warn programmers about pretend_object_file() that allows the code
59 to tentatively use in-core objects.
61 * The way "git pack-objects" reuses objects stored in existing pack
62 to generate its result has been improved.
64 * The transport protocol version 2 becomes the default one.
66 * Traditionally, we avoided threaded grep while searching in objects
67 (as opposed to files in the working tree) as accesses to the object
68 layer is not thread-safe. This limitation is getting lifted.
70 * "git rebase -i" (and friends) used to unnecessarily check out the
71 tip of the branch to be rebased, which has been corrected.
73 * A low-level API function get_oid(), that accepts various ways to
74 name an object, used to issue end-user facing error messages
75 without l10n, which has been updated to be translatable.
77 * Unneeded connectivity check is now disabled in a partial clone when
78 fetching into it.
80 * Some rough edges in the sparse-checkout feature, especially around
81 the cone mode, have been cleaned up.
83 * The diff-* plumbing family of subcommands now pay attention to the
84 diff.wsErrorHighlight configuration, which has been ignored before;
85 this allows "git add -p" to also show the whitespace problems to
86 the end user.
88 * Some codepaths were given a repository instance as a parameter to
89 work in the repository, but passed the_repository instance to its
90 callees, which has been cleaned up (somewhat).
92 * Memory footprint and performance of "git name-rev" has been
93 improved.
96 Fixes since v2.25
97 -----------------
99 * "git commit" gives output similar to "git status" when there is
100 nothing to commit, but without honoring the advise.statusHints
101 configuration variable, which has been corrected.
103 * has_object_file() said "no" given an object registered to the
104 system via pretend_object_file(), making it inconsistent with
105 read_object_file(), causing lazy fetch to attempt fetching an
106 empty tree from promisor remotes.
108 * Complete an update to tutorial that encourages "git switch" over
109 "git checkout" that was done only half-way.
111 * C pedantry ;-) fix.
113 * The code that tries to skip over the entries for the paths in a
114 single directory using the cache-tree was not careful enough
115 against corrupt index file.
117 * Reduce unnecessary round-trip when running "ls-remote" over the
118 stateless RPC mechanism.
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.
124 * The code recently added to move to the entry beyond the ones in the
125 same directory in the index in the sparse-cone mode did not count
126 the number of entries to skip over incorrectly, which has been
127 corrected.
129 * Rendering by "git log --graph" of ancestry lines leading to a merge
130 commit were made suboptimal to waste vertical space a bit with a
131 recent update, which has been corrected.
133 * Work around test breakages caused by custom regex engine used in
134 libasan, when address sanitizer is used with more recent versions
135 of gcc and clang.
137 * Minor bugfixes to "git add -i" that has recently been rewritten in C.
138 (merge 849e43cc18 js/builtin-add-i-cmds later to maint).
140 * "git fetch --refmap=" option has got a better documentation.
142 * "git checkout X" did not correctly fail when X is not a local
143 branch but could name more than one remote-tracking branches
144 (i.e. to be dwimmed as the starting point to create a corresponding
145 local branch), which has been corrected.
146 (merge fa74180d08 am/checkout-file-and-ref-ref-ambiguity later to maint).
148 * Corner case bugs in "git clean" that stems from a (necessarily for
149 performance reasons) awkward calling convention in the directory
150 enumeration API has been corrected.
152 * A fetch that is told to recursively fetch updates in submodules
153 inevitably produces reams of output, and it becomes hard to spot
154 error messages. The command has been taught to enumerate
155 submodules that had errors at the end of the operation.
156 (merge 0222540827 es/fetch-show-failed-submodules-atend later to maint).
158 * The "--recurse-submodules" option of various subcommands did not
159 work well when run in an alternate worktree, which has been
160 corrected.
161 (merge a9472afb63 pb/recurse-submodule-in-worktree-fix later to maint).
163 * Futureproofing a test not to depend on the current implementation
164 detail.
166 * Running "git rm" on a submodule failed unnecessarily when
167 .gitmodules is only cache-dirty, which has been corrected.
168 (merge 7edee32985 dt/submodule-rm-with-stale-cache later to maint).
170 * C pedantry ;-) fix.
171 (merge cf82bff73f jk/clang-sanitizer-fixes later to maint).
173 * "git grep --no-index" should not get affected by the contents of
174 the .gitmodules file but when "--recurse-submodules" is given or
175 the "submodule.recurse" variable is set, it did. Now these
176 settings are ignored in the "--no-index" mode.
178 * Technical details of the bundle format has been documented.
180 * Unhelpful warning messages during documentation build have been squelched.
182 * "git rebase -i" identifies existing commits in its todo file with
183 their abbreviated object name, which could become ambigous as it
184 goes to create new commits, and has a mechanism to avoid ambiguity
185 in the main part of its execution. A few other cases however were
186 not covered by the protection against ambiguity, which has been
187 corrected.
188 (merge 26027625dd js/rebase-i-with-colliding-hash later to maint).
190 * Allow the rebase.missingCommitsCheck configuration to kick in when
191 "rebase --edit-todo" and "rebase --continue" restarts the procedure.
192 (merge 5a5445d878 ag/edit-todo-drop-check later to maint).
194 * The way "git submodule status" reports an initialized but not yet
195 populated submodule has not been reimplemented correctly when a
196 part of the "git submodule" command was rewritten in C, which has
197 been corrected.
198 (merge f38c92452d pk/status-of-uncloned-submodule later to maint).
200 * The code to automatically shrink the fan-out in the notes tree had
201 an off-by-one bug, which has been killed.
202 (merge dbc27477ff jh/notes-fanout-fix later to maint).
204 * The index-pack code now diagnoses a bad input packstream that
205 records the same object twice when it is used as delta base; the
206 code used to declare a software bug when encountering such an
207 input, but it is an input error.
208 (merge a21781011f jk/index-pack-dupfix later to maint).
210 * The code to compute the commit-graph has been taught to use a more
211 robust way to tell if two object directories refer to the same
212 thing.
213 (merge a7df60cac8 tb/commit-graph-object-dir later to maint).
215 * Other code cleanup, docfix, build fix, etc.
216 (merge 26f924d50e en/simplify-check-updates-in-unpack-trees later to maint).
217 (merge d0d0a357a1 am/update-pathspec-f-f-tests later to maint).
218 (merge f94f7bd00d am/test-pathspec-f-f-error-cases later to maint).
