1 Git v2.45 Release Notes
2 =======================
4 Backward Compatibility Notes
6 UI, Workflows & Features
8 * Integrate the reftable code into the refs framework as a backend.
9 With "git init --ref-format=reftable", hopefully it would be a lot
10 more efficient to manage a repository with many references.
12 * "git checkout -p" and friends learned that that "@" is a synonym
13 for "HEAD".
15 * Variants of vimdiff learned to honor mergetool.<variant>.layout
16 settings.
18 * "git reflog" learned a "list" subcommand that enumerates known reflogs.
20 * When a merge conflicted at a submodule, merge-ort backend used to
21 unconditionally give a lengthy message to suggest how to resolve
22 it. Now the message can be squelched as an advice message.
24 * "git for-each-ref" learned "--include-root-refs" option to show
25 even the stuff outside the 'refs/' hierarchy.
27 * "git rev-list --missing=print" has learned to optionally take
28 "--allow-missing-tips", which allows the objects at the starting
29 points to be missing.
31 * "git merge-tree" has learned that the three trees involved in the
32 3-way merge only need to be trees, not necessarily commits.
34 * "git log --merge" learned to pay attention to CHERRY_PICK_HEAD and
35 other kinds of *_HEAD pseudorefs.
38 Performance, Internal Implementation, Development Support etc.
40 * The code to iterate over refs with the reftable backend has seen
41 some optimization.
43 * More tests that are marked as "ref-files only" have been updated to
44 improve test coverage of reftable backend.
46 * Some parts of command line completion script (in contrib/) have
47 been micro-optimized.
49 * The way placeholders are to be marked-up in documentation have been
50 specified; use "_<placeholder>_" to typeset the word inside a pair
51 of <angle-brakets> emphasized.
53 * "git --no-lazy-fetch cmd" allows to run "cmd" while disabling lazy
54 fetching of objects from the promisor remote, which may be handy
55 for debugging.
57 * The implementation in "git clean" that makes "-n" and "-i" ignore
58 clean.requireForce has been simplified, together with the
59 documentation.
61 * The code to iterate over refs with the reftable backend has seen
62 some optimization.
65 Fixes since v2.44
66 -----------------
68 * "git apply" on a filesystem without filemode support have learned
69 to take a hint from what is in the index for the path, even when
70 not working with the "--index" or "--cached" option, when checking
71 the executable bit match what is required by the preimage in the
72 patch.
73 (merge 45b625142d cp/apply-core-filemode later to maint).
75 * "git column" has been taught to reject negative padding value, as
76 it would lead to nonsense behaviour including division by zero.
77 (merge 76fb807faa kh/column-reject-negative-padding later to maint).
79 * "git am --help" now tells readers what actions are available in
80 "git am --whitespace=<action>", in addition to saying that the
81 option is passed through to the underlying "git apply".
82 (merge a171dac734 jc/am-whitespace-doc later to maint).
84 * "git tag --column" failed to check the exit status of its "git
85 column" invocation, which has been corrected.
86 (merge 92e66478fc rj/tag-column-fix later to maint).
88 * Credential helper based on libsecret (in contrib/) has been updated
89 to handle an empty password correctly.
90 (merge 8f1f2023b7 mh/libsecret-empty-password-fix later to maint).
92 * "git difftool --dir-diff" learned to honor the "--trust-exit-code"
93 option; it used to always exit with 0 and signalled success.
94 (merge eb84c8b6ce ps/difftool-dir-diff-exit-code later to maint).
96 * The code incorrectly attempted to use textconv cache when asked,
97 even when we are not running in a repository, which has been
98 corrected.
99 (merge affe355fe7 jk/textconv-cache-outside-repo-fix later to maint).
101 * Remove an empty file that shouldn't have been added in the first
102 place.
103 (merge 4f66942215 js/remove-cruft-files later to maint).
105 * The logic to access reflog entries by date and number had ugly
106 corner cases at the boundaries, which have been cleaned up.
107 (merge 5edd126720 jk/reflog-special-cases-fix later to maint).
109 * An error message from "git upload-pack", which responds to "git
110 fetch" requests, had a trialing NUL in it, which has been
111 corrected.
112 (merge 3f4c7a0805 sg/upload-pack-error-message-fix later to maint).
114 * Clarify wording in the CodingGuidelines that requires <git-compat-util.h>
115 to be the first header file.
116 (merge 4e89f0e07c jc/doc-compat-util later to maint).
118 * "git commit -v --cleanup=scissors" used to add the scissors line
119 twice in the log message buffer, which has been corrected.
120 (merge e90cc075cc jt/commit-redundant-scissors-fix later to maint).
122 * A custom remote helper no longer cannot access the newly created
123 repository during "git clone", which is a regression in Git 2.44.
124 This has been corrected.
125 (merge 199f44cb2e ps/remote-helper-repo-initialization-fix later to maint).
127 * Various parts of upload-pack has been updated to bound the resource
128 consumption relative to the size of the repository to protect from
129 abusive clients.
130 (merge 6cd05e768b jk/upload-pack-bounded-resources later to maint).
132 * The upload-pack program, when talking over v2, accepted the
133 packfile-uris protocol extension from the client, even if it did
134 not advertise the capability, which has been corrected.
135 (merge a922bfa3b5 jk/upload-pack-v2-capability-cleanup later to maint).
137 * Make sure failure return from merge_bases_many() is properly caught.
138 (merge 25fd20eb44 js/merge-base-with-missing-commit later to maint).
140 * FSMonitor client code was confused when FSEvents were given in a
141 different case on a case-insensitive filesystem, which has been
142 corrected.
143 (merge 29c139ce78 jh/fsmonitor-icase-corner-case-fix later to maint).
145 * The "core.commentChar" configuration variable only allows an ASCII
146 character, which was not clearly documented, which has been
147 corrected.
148 (merge fb7c556f58 kh/doc-commentchar-is-a-byte later to maint).
150 * With release 2.44 we got rid of all uses of test_i18ngrep and there
151 is no in-flight topic that adds a new use of it. Make a call to
152 test_i18ngrep a hard failure, so that we can remove it at the end
153 of this release cycle.
154 (merge 381a83dfa3 jc/test-i18ngrep later to maint).
156 * The command line completion script (in contrib/) learned to
157 complete "git reflog" better.
158 (merge 1284f9cc11 rj/complete-reflog later to maint).
160 * The logic to complete the command line arguments to "git worktree"
161 subcommand (in contrib/) has been updated to correctly honor things
162 like "git -C dir" etc.
163 (merge 3574816d98 rj/complete-worktree-paths-fix later to maint).
165 * Other code cleanup, docfix, build fix, etc.
166 (merge f0e578c69c rs/use-xstrncmpz later to maint).
167 (merge 83e6eb7d7a ba/credential-test-clean-fix later to maint).
168 (merge 64562d784d jb/doc-interactive-singlekey-do-not-need-perl later to maint).
