1 Git v2.41 Release Notes
2 =======================
4 UI, Workflows & Features
6 * Allow information carried on the WWW-AUthenticate header to be
7 passed to the credential helpers.
9 * A new "fetch.hideRefs" option can be used to exclude specified refs
10 from "rev-list --objects --stdin --not --all" traversal for
11 checking object connectivity, most useful when there are many
12 unrelated histories in a single repository.
14 * "git push" has been taught to allow deletion of refs with one-level
15 names to help repairing a repository who acquired such a ref by
16 mistake. In general, we don't encourage use of such a ref, and
17 creation or update to such a ref is rejected as before.
19 * Allow "git bisect reset" to check out the original branch when the
20 branch is already checked out in a different worktree linked to the
21 same repository.
23 * A few subcommands have been taught to stop users from working on a
24 branch that is being used in another worktree linked to the same
25 repository.
27 * "git format-patch" learned to write a log-message only output file
28 for empty commits.
30 * "git format-patch" honors the src/dst prefixes set to nonstandard
31 values with configuration variables like "diff.noprefix", causing
32 receiving end of the patch that expects the standard -p1 format to
33 break. "format-patch" has been taught to ignore end-user configuration
34 and always use the standard prefixes.
36 This is a backward compatibility breaking change.
38 * Lift the limitation that colored prompts can only be used with
39 PROMPT_COMMAND mode.
41 * "git blame --contents=<file> <rev> -- <path>" used to be forbidden,
42 but now it finds the origins of lines starting at <file> contents
43 through the history that leads to <rev>.
45 * "git pack-redundant" gave a warning when run, as the command has
46 outlived its usefulness long ago and is nominated for future
47 removal. Now we escalate to give an error.
49 * "git clone" from an empty repository learned to propagate the
50 choice of the hash algorithm from the source repository to the
51 newly created repository.
53 * "git mergetool" and "git difftool" learns a new configuration
54 guiDefault to optionally favor configured guitool over non-gui-tool
55 automatically when $DISPLAY is set.
57 * "git branch -d origin/master" would say "no such branch", but it is
58 likely a missed "-r" if refs/remotes/origin/master exists. The
59 command has been taught to give such a hint in its error message.
61 * Clean-up of the code path that deals with merge strategy option
62 handling in "git rebase".
65 Performance, Internal Implementation, Development Support etc.
67 * Code clean-up to clarify directory traversal API.
69 * Code clean-up to clarify the rule that "git-compat-util.h" must be
70 the first to be included.
72 * More work towards -Wunused.
74 * Instead of forcing each command to choose to honor GPG related
75 configuration variables, make the subsystem lazily initialize
76 itself.
78 * Remove workaround for ancient versions of DocBook to make it work
79 correctly with groff, which has not been necessary since docbook
80 1.76 from 2010.
82 * Code clean-up to include and/or uninclude parse-options.h file as
83 needed.
85 * The code path that reports what "git fetch" did to each ref has
86 been cleaned up.
88 * Assorted config API updates.
90 * A few configuration variables to tell the cURL library that
91 different types of ssl-cert and ssl-key are in use have been added.
93 * Split key function and data structure definitions out of cache.h to
94 new header files and adjust the users.
96 * "git fetch --all" does not have to download and handle the same
97 bundleURI over and over, which has been corrected.
99 * "git sparse-checkout" command learns a debugging aid for the sparse
100 rule definitions.
102 * "git write-tree" learns to work better with sparse-index.
106 Fixes since v2.40
107 -----------------
109 * "git fsck" learned to check the index files in other worktrees,
110 just like "git gc" honors them as anchoring points.
111 (merge 8d3e7eac52 jk/fsck-indices-in-worktrees later to maint).
113 * Fix a segfaulting loop. The function and its caller may need
114 further clean-up.
115 (merge c5773dc078 ew/commit-reach-clean-up-flags-fix later to maint).
117 * "git restore" supports options like "--ours" that are only
118 meaningful during a conflicted merge, but these options are only
119 meaningful when updating the working tree files. These options are
120 marked to be incompatible when both "--staged" and "--worktree" are
121 in effect.
122 (merge ee8a88826a ak/restore-both-incompatible-with-conflicts later to maint).
124 * Simplify UI to control progress meter given by "git bundle" command.
125 (merge 8b95521edb jk/bundle-progress later to maint).
127 * "git bundle" learned that "-" is a common way to say that the input
128 comes from the standard input and/or the output goes to the
129 standard output. It used to work only for output and only from the
130 root level of the working tree.
131 (merge 0bbe10313e jk/bundle-use-dash-for-stdfiles later to maint).
133 * Once we start running, we assumed that the list of alternate object
134 databases would never change. Hook into the machinery used to
135 update the list of packfiles during runtime to update this list as
136 well.
137 (merge e2d003dbed ds/reprepare-alternates-when-repreparing-packfiles later to maint).
139 * The code to parse "git rebase -X<opt>" was not prepared to see an
140 unparsable option string, which has been corrected.
141 (merge 15a4cc912e ab/fix-strategy-opts-parsing later to maint).
143 * "git add -p" while the index is unmerged sometimes failed to parse
144 the diff output it internally produces and died, which has been
145 corrected.
146 (merge 28d1122f9c jk/add-p-unmerged-fix later to maint).
148 * Fix for a "ls-files --format="%(path)" that produced nonsense
149 output, which was a bug in 2.38.
150 (merge cfb62dd006 aj/ls-files-format-fix later to maint).
152 * "git receive-pack" that responds to "git push" requests failed to
153 clean a stale lockfile when killed in the middle, which has been
154 corrected.
155 (merge c55c30669c ps/receive-pack-unlock-before-die later to maint).
157 * "git rev-parse --quiet foo@{u}", or anything that asks @{u} to be
158 parsed with GET_OID_QUIETLY option, did not quietly fail, which has
159 been corrected.
160 (merge dfbfdc521d fc/oid-quietly-parse-upstream later to maint).
162 * Transports that do not support protocol v2 did not correctly fall
163 back to protocol v0 under certain conditions, which has been
164 corrected.
165 (merge eaa0fd6584 jk/fix-proto-downgrade-to-v0 later to maint).
167 * time(2) on glib 2.31+, especially on Linux, goes out of sync with
168 higher resolution timers used for gettimeofday(2) and by the
169 filesystem. Replace all calls to it with a git_time() wrapper and
170 (merge 370ddcbc89 pe/time-use-gettimeofday later to maint).
172 * Code clean-up to use designated initializers in parse-options API.
173 (merge 353e6d4554 sg/parse-options-h-initializers later to maint).
175 * A recent-ish change to allow unicode character classes to be used
176 with "grep -P" triggered a JIT bug in older pcre2 libraries.
177 The problematic change in Git built with these older libraries has
178 been disabled to work around the bug.
179 (merge 14b9a04479 mk/workaround-pcre-jit-ucp-bug later to maint).
181 * The wildmatch library code unlearns exponential behaviour it
182 acquired some time ago since it was borrowed from rsync.
183 (merge 3dc0b7f0dc pw/wildmatch-fixes later to maint).
185 * The index files can become corrupt under certain conditions when
186 the split-index feature is in use, especially together with
187 fsmonitor, which have been corrected.
188 (merge 061dd722dc js/split-index-fixes later to maint).
190 * Document what the pathname-looking strings in "rev-list --object"
191 output are for and what they mean.
192 (merge 15364d2a3c jk/document-rev-list-object-name later to maint).
194 * Fix unnecessary truncation of generation numbers used in-core.
195 (merge d3af1c193d ps/ahead-behind-truncation-fix later to maint).
197 * Code clean-up around the use of the_repository.
198 (merge 4a93b899c1 ab/remove-implicit-use-of-the-repository later to maint).
200 * Consistently spell "Message-ID" as such, not "Message-Id".
201 (merge ba4324c4e1 jc/spell-id-in-both-caps-in-message-id later to maint).
203 * Correct use of an uninitialized structure member.
204 (merge dc12ee77ab jx/cap-object-info-uninitialized-fix later to maint).
206 * Tests had a few places where we ignored PERL_PATH and blindly used
207 /usr/bin/perl, which have been corrected.
208 (merge c1917156a0 jk/use-perl-path-consistently later to maint).
210 * Documentation mark-up fix.
211 (merge 78b6369e67 la/mfc-markup-fix later to maint).
213 * Doc toolchain update to remove old workaround for AsciiDoc.
214 (merge 8806120de6 fc/remove-header-workarounds-for-asciidoc later to maint).
216 * Other code cleanup, docfix, build fix, etc.
