1 Git 2.28 Release Notes
2 ======================
4 Updates since v2.27
5 -------------------
7 Backward compatibility notes
9 * "feature.experimental" configuration variable is to let volunteers
10 easily opt into a set of newer features, which use of the v2
11 transport protocol is now a part of.
13 * It used to be that setting extensions.* configuration variables
14 alone, while leaving core.repositoryFormatVersion=0, made these
15 settings effective, which was a wrong thing to do. In version 0,
16 there was no special meaning in extensions.* configuration
17 variables. This has been corrected. If you need these repository
18 extensions to be effective, the core.repositoryFormatVersion
19 variable needs to be updated to 1 after vetting these extensions.*
20 variables are set correctly.
23 UI, Workflows & Features
25 * The commands in the "diff" family learned to honor "diff.relative"
26 configuration variable.
28 * The check in "git fsck" to ensure that the tree objects are sorted
29 still had corner cases it missed unsorted entries.
31 * The interface to redact sensitive information in the trace output
32 has been simplified.
34 * The command line completion (in contrib/) learned to complete
35 options that the "git switch" command takes.
37 * "git diff" used to take arguments in random and nonsense range
38 notation, e.g. "git diff A..B C", "git diff A..B C...D", etc.,
39 which has been cleaned up.
41 * "git diff-files" has been taught to say paths that are marked as
42 intent-to-add are new files, not modified from an empty blob.
45 Performance, Internal Implementation, Development Support etc.
47 * Code optimization for a common case.
48 (merge 8777616e4d an/merge-single-strategy-optim later to maint).
50 * We've adopted a convention that any on-stack structure can be
51 initialized to have zero values in all fields with "= { 0 }",
52 even when the first field happens to be a pointer, but sparse
53 complained that a null pointer should be spelled NULL for a long
54 time. Start using -Wno-universal-initializer option to squelch
55 it (the latest sparse has it on by default).
57 * "git log -L..." now takes advantage of the "which paths are touched
58 by this commit?" info stored in the commit-graph system.
60 * As FreeBSD is not the only platform whose regexp library reports
61 a REG_ILLSEQ error when fed invalid UTF-8, add logic to detect that
62 automatically and skip the affected tests.
64 * "git bugreport" learns to report what shell is in use.
66 * Support for GIT_CURL_VERBOSE has been rewritten in terms of
67 GIT_TRACE_CURL.
69 * Preliminary clean-ups around refs API, plus file format
70 specification documentation for the reftable backend.
72 * Workaround breakage in MSVC build, where "curl-config --cflags"
73 gives settings appropriate for GCC build.
75 * Code clean-up of "git clean" resulted in a fix of recent
76 performance regression.
78 * Code clean-up in the codepath that serves "git fetch" continues.
80 * "git merge-base --is-ancestor" is taught to take advantage of the
81 commit graph.
83 * Rewrite of parts of the scripted "git submodule" Porcelain command
84 continues; this time it is "git submodule set-branch" subcommand's
85 turn.
87 * The "fetch/clone" protocol has been updated to allow the server to
88 instruct the clients to grab pre-packaged packfile(s) in addition
89 to the packed object data coming over the wire.
91 * A misdesigned strbuf_write_fd() function has been retired.
95 Fixes since v2.27
96 -----------------
98 * The "--prepare-p4-only" option of "git p4" is supposed to stop
99 after replaying one changeset, but kept going (by mistake?)
101 * The error message from "git checkout -b foo -t bar baz" was
102 confusing.
104 * Some repositories in the wild have commits that record nonsense
105 committer timezone (e.g. rails.git); "git fast-import" learned an
106 option to pass these nonsense timestamps intact to allow recreating
107 existing repositories as-is.
108 (merge d42a2fb72f en/fast-import-looser-date later to maint).
110 * The command line completion script (in contrib/) tried to complete
111 "git stash -p" as if it were "git stash push -p", but it was too
112 aggressive and also affected "git stash show -p", which has been
113 corrected.
114 (merge fffd0cf520 vs/complete-stash-show-p-fix later to maint).
116 * On-the-wire protocol v2 easily falls into a deadlock between the
117 remote-curl helper and the fetch-pack process when the server side
118 prematurely throws an error and disconnects. The communication has
119 been updated to make it more robust.
121 * "git checkout -p" did not handle a newly added path at all.
122 (merge 2c8bd8471a js/checkout-p-new-file later to maint).
124 * The code to parse "git bisect start" command line was lax in
125 validating the arguments.
126 (merge 4d9005ff5d cb/bisect-helper-parser-fix later to maint).
128 * Reduce memory usage during "diff --quiet" in a worktree with too
129 many stat-unmatched paths.
130 (merge d2d7fbe129 jk/diff-memuse-optim-with-stat-unmatch later to maint).
132 * The reflog entries for "git clone" and "git fetch" did not
133 anonymize the URL they operated on.
134 (merge 46da295a77 js/reflog-anonymize-for-clone-and-fetch later to maint).
136 * The behaviour of "sparse-checkout" in the state "git clone
137 --no-checkout" left was changed accidentally in 2.27, which has
138 been corrected.
140 * Use of negative pathspec, while collecting paths including
141 untracked ones in the working tree, was broken.
143 * The same worktree directory must be registered only once, but
144 "git worktree move" allowed this invariant to be violated, which
145 has been corrected.
146 (merge 810382ed37 es/worktree-duplicate-paths later to maint).
148 * The effect of sparse checkout settings on submodules is documented.
149 (merge e7d7c73249 en/sparse-with-submodule-doc later to maint).
151 * Code clean-up around "git branch" with a minor bugfix.
152 (merge dc44639904 dl/branch-cleanup later to maint).
154 * A branch name used in a test has been clarified to match what is
155 going on.
156 (merge 08dc26061f pb/t4014-unslave later to maint).
158 * An in-code comment in "git diff" has been updated.
159 (merge c592fd4c83 dl/diff-usage-comment-update later to maint).
161 * Other code cleanup, docfix, build fix, etc.
162 (merge 2c31a7aa44 jx/pkt-line-doc-count-fix later to maint).
163 (merge d63ae31962 cb/t5608-cleanup later to maint).
164 (merge 788db145c7 dl/t-readme-spell-git-correctly later to maint).
165 (merge 45a87a83bb dl/python-2.7-is-the-floor-version later to maint).
166 (merge b75a219904 es/advertise-contribution-doc later to maint).
167 (merge 0c9a4f638a rs/pull-leakfix later to maint).
