1 Git v2.44 Release Notes
2 =======================
4 Backward Compatibility Notes
6 * "git chekcout -B <branch>" used to allow switching to a branch that
7 is in use on another worktree, but this was by mistake. The users
8 need to use "--ignore-other-worktrees" option.
11 UI, Workflows & Features
13 * "git add" and "git stash" learned to support the ":(attr:...)"
16 * "git rebase --autosquash" is now enabled for non-interactive rebase,
17 but it is still incompatible with the apply backend.
19 * Introduce "git replay", a tool meant on the server side without
20 working tree to recreate a history.
22 * "git merge-file" learned to take the "--diff-algorithm" option to
23 use algorithm different from the default "myers" diff.
25 * Command line completion (in contrib/) learned to complete path
26 arguments to the "add/set" subcommands of "git sparse-checkout"
29 * "git checkout -B <branch> [<start-point>]" allowed a branch that is
30 in use in another worktree to be updated and checked out, which
31 might be a bit unexpected. The rule has been tightened, which is a
32 breaking change. "--ignore-other-worktrees" option is required to
33 unbreak you, if you are used to the current behaviour that "-B"
36 * The builtin_objectmode attribute is populated for each path
37 without adding anything in .gitattributes files, which would be
38 useful in magic pathspec, e.g., ":(attr:builtin_objectmode=100755)"
39 to limit to executables.
41 * "git fetch" learned to pay attention to "fetch.all" configuration
42 variable, which pretends as if "--all" was passed from the command
43 line when no remote parameter was given.
45 * In addition to (rather cryptic) Security Identifiers, show username
46 and domain in the error message when we barf on mismatch between
47 the Git directory and the current user on Windows.
49 * The error message given when "git branch -d branch" fails due to
50 commits unique to the branch has been split into an error and a new
51 conditional advice message.
53 * When given an existing but unreadable file as a configuration file,
54 gitweb behaved as if the file did not exist at all, but now it
55 errors out. This is a change that may break backward compatibility.
57 * When $HOME/.gitignore is missing but XDG config file available, we
58 should write into the latter, not former. "git gc" and "git
59 maintenance" wrote into a wrong "global config" file, which have
63 Performance, Internal Implementation, Development Support etc.
65 * Process to add some form of low-level unit tests has started.
67 * Add support for GitLab CI.
69 * "git for-each-ref --no-sort" still sorted the refs alphabetically
70 which paid non-trivial cost. It has been redefined to show output
71 in an unspecified order, to allow certain optimizations to take
74 * Simplify API implementation to delete references by eliminating
77 * Subject approxidate() and show_date() machinery to OSS-Fuzz.
79 * A new helper to let us pretend that we called lstat() when we know
80 our cache_entry is up-to-date via fsmonitor.
82 * The optimization based on fsmonitor in the "diff --cached"
83 codepath is resurrected with the "fake-lstat" introduced earlier.
85 * Test balloon to use C99 "bool" type from <stdbool.h> has been
88 * "git clone" has been prepared to allow cloning a repository with
89 non-default hash function into a repository that uses the reftable
92 * Streaming spans of packfile data used to be done only from a
93 single, primary, pack in a repository with multiple packfiles. It
94 has been extended to allow reuse from other packfiles, too.
96 * Comment updates to help developers not to attempt to modify
97 messages from plumbing commands that must stay constant.
99 It might make sense to reassess the plumbing needs every few years,
100 but that should be done as a separate effort.
102 * Move test-ctype helper to the unit-test framework.
104 * Instead of manually creating refs/ hierarchy on disk upon a
105 creation of a secondary worktree, which is only usable via the
106 files backend, use the refs API to populate it.
108 * CI for GitLab learned to drive macOS jobs.
110 * A few tests to "git commit -o <pathspec>" and "git commit -i
111 <pathspec>" has been added.
117 * The way CI testing used "prove" could lead to running the test
118 suite twice needlessly, which has been corrected.
119 (merge e7e03ef995 js/ci-discard-prove-state later to maint).
121 * Update ref-related tests.
123 * "git format-patch --encode-email-headers" ignored the option when
124 preparing the cover letter, which has been corrected.
126 * Newer versions of Getopt::Long started giving warnings against our
127 (ab)use of it in "git send-email". Bump the minimum version
128 requirement for Perl to 5.8.1 (from September 2002) to allow
129 simplifying our implementation.
130 (merge 6ff658cc78 tz/send-email-negatable-options later to maint).
132 * Earlier we stopped relying on commit-graph that (still) records
133 information about commits that are lost from the object store,
134 which has negative performance implications. The default has been
135 flipped to disable this pessimization.
136 (merge b1df3b3867 ps/commit-graph-less-paranoid later to maint).
138 * Stale URLs have been updated to their current counterparts (or
139 archive.org) and HTTP links are replaced with working HTTPS links.
140 (merge 62b4f7b9c6 js/update-urls-in-doc-and-comment later to maint).
142 * trace2 streams used to record the URLs that potentially embed
143 authentication material, which has been corrected.
144 (merge 16fa3eebc0 jh/trace2-redact-auth later to maint).
146 * The sample pre-commit hook that tries to catch introduction of new
147 paths that use potentially non-portable characters did not notice
148 an existing path getting renamed to such a problematic path, when
149 rename detection was enabled.
150 (merge d9fd71fa2a jp/use-diff-index-in-pre-commit-sample later to maint).
152 * The command line parser for the "log" family of commands was too
153 loose when parsing certain numbers, e.g., silently ignoring the
154 extra 'q' in "git log -n 1q" without complaining, which has been
156 (merge 71a1e94821 jc/revision-parse-int later to maint).
158 * "git $cmd --end-of-options --rev -- --path" for some $cmd failed
159 to interpret "--rev" as a rev, and "--path" as a path. This was
160 fixed for many programs like "reset" and "checkout".
161 (merge 9385174627 jk/end-of-options later to maint).
163 * "git bisect reset" has been taught to clean up state files and refs
164 even when BISECT_START file is gone.
165 (merge daaa03e54c jk/bisect-reset-fix later to maint).
167 * Some codepaths did not correctly parse configuration variables
168 specified with valueless "true", which has been corrected.
169 (merge d49cb162fa jk/implicit-true later to maint).
171 * Code clean-up for sanity checking of command line options for "git
173 (merge 7382497372 rs/show-ref-incompatible-options later to maint).
175 * The code to parse the From e-mail header has been updated to avoid
177 (merge dee182941f jk/mailinfo-iterative-unquote-comment later to maint).
179 * "git fetch --atomic" issued an unnecessary empty error message,
180 which has been corrected.
181 (merge 18ce48918c jx/fetch-atomic-error-message-fix later to maint).
183 * Command line completion script (in contrib/) learned to work better
184 with the reftable backend.
185 (merge 44dbb3bf29 sh/completion-with-reftable later to maint).
187 * "git status" is taught to show both the branch being bisected and
188 being rebased when both are in effect at the same time.
189 (merge 990adccbdf rj/status-bisect-while-rebase later to maint).
191 * "git archive --list extra garbage" silently ignored excess command
192 line parameters, which has been corrected.
193 (merge d6b6cd1393 jc/archive-list-with-extra-args later to maint).
195 * "git sparse-checkout set" added default patterns even when the
196 patterns are being fed from the standard input, which has been
198 (merge 53ded839ae jc/sparse-checkout-set-default-fix later to maint).
200 * "git sparse-checkout (add|set) --[no-]cone --end-of-options" did
201 not handle "--end-of-options" correctly after a recent update.
203 * Unlike other environment variables that took the usual
204 true/false/yes/no as well as 0/1, GIT_FLUSH only understood 0/1,
205 which has been corrected.
206 (merge 556e68032f cp/git-flush-is-an-env-bool later to maint).
208 * Clearing in-core repository (happens during e.g., "git fetch
209 --recurse-submodules" with commit graph enabled) made in-core
210 commit object in an inconsistent state by discarding the necessary
211 data from commit-graph too early, which has been corrected.
212 (merge d70f554cdf jk/commit-graph-slab-clear-fix later to maint).
214 * Other code cleanup, docfix, build fix, etc.
215 (merge 50f1abcff6 js/packfile-h-typofix later to maint).
