1 Git v2.38 Release Notes
2 =======================
4 UI, Workflows & Features
6 * "git remote show [-n] frotz" now pays attention to negative
7 pathspec.
9 * "git push" sometimes perform poorly when reachability bitmaps are
10 used, even in a repository where other operations are helped by
11 bitmaps. The push.useBitmaps configuration variable is introduced
12 to allow disabling use of reachability bitmaps only for "git push".
14 * "git grep -m<max-hits>" is a way to limit the hits shown per file.
16 * "git merge-tree" learned a new mode where it takes two commits and
17 computes a tree that would result in the merge commit, if the
18 histories leading to these two commits were to be merged.
20 * "git mv A B" in a sparsely populated working tree can be asked to
21 move a path between directories that are "in cone" (i.e. expected
22 to be materialized in the working tree) and "out of cone"
23 (i.e. expected to be hidden). The handling of such cases has been
24 improved.
26 * Earlier, HTTP transport clients learned to tell the server side
27 what locale they are in by sending Accept-Language HTTP header, but
28 this was done only for some requests but not others.
30 * Introduce a discovery.barerepository configuration variable that
31 allows users to forbid discovery of bare repositories.
33 * Various messages that come from the pack-bitmap codepaths have been
34 tweaked.
36 * "git rebase -i" learns to update branches whose tip appear in the
37 rebased range with "--update-refs" option.
40 Performance, Internal Implementation, Development Support etc.
42 * Collection of what is referenced by objects in promisor packs have
43 been optimized to inspect these objects in the in-pack order.
45 * Introduce a helper to see if a branch is already being worked on
46 (hence should not be newly checked out in a working tree), which
47 performs much better than the existing find_shared_symref() to
48 replace many uses of the latter.
50 * Teach "git archive" to (optionally and then by default) avoid
51 spawning an external "gzip" process when creating ".tar.gz" (and
52 ".tgz") archives.
54 * Allow large objects read from a packstream to be streamed into a
55 loose object file straight, without having to keep it in-core as a
56 whole.
58 * Further preparation to turn git-submodule.sh into a builtin
59 continues.
61 * Apply Coccinelle rule to turn raw memmove() into MOVE_ARRAY() cpp
62 macro, which would improve maintainability and readability.
64 * Teach "make all" to build gitweb as well.
66 * Tweak tests so that they still work when the "git init" template
67 did not create .git/info directory.
69 * Add Coccinelle rules to detect the pattern of initializing and then
70 finalizing a structure without using it in between at all, which
71 happens after code restructuring and the compilers fail to
72 recognize as an unused variable.
74 * The code to convert between GPG trust level strings and internal
75 constants we use to represent them have been cleaned up.
77 * Support for libnettle as SHA256 implementation has been added.
79 * The way "git multi-pack" uses parse-options API has been improved.
81 * A coccinelle rule (in contrib/) to encourage use of COPY_ARRAY
82 macro has been improved.
84 * API tweak to make it easier to run fuzz testing on commit-graph parser.
86 * Omit fsync-related trace2 entries when their values are all zero.
89 Fixes since v2.37
90 -----------------
92 * Rewrite of "git add -i" in C that appeared in Git 2.25 didn't
93 correctly record a removed file to the index, which was fixed.
95 * Certain diff options are currently ignored when combined-diff is
96 shown; mark them as incompatible with the feature.
98 * Adjust technical/bitmap-format to be formatted by AsciiDoc, and
99 add some missing information to the documentation.
101 * Fixes for tests when the source directory has unusual characters in
102 its path, e.g. whitespaces, double-quotes, etc.
104 * "git mktree --missing" lazily fetched objects that are missing from
105 the local object store, which was totally unnecessary for the purpose
106 of creating the tree object(s) from its input.
108 * Give _() markings to fatal/warning/usage: labels that are shown in
109 front of these messages.
111 * References to commands-to-be-typed-literally in "git rebase"
112 documentation mark-up have been corrected.
114 * In a non-bare repository, the behavior of Git when the
115 core.worktree configuration variable points at a directory that has
116 a repository as its subdirectory, regressed in Git 2.27 days.
118 * Recent update to vimdiff layout code has been made more robust
119 against different end-user vim settings.
121 * Plug various memory leaks.
122 (merge ece3974ba6 ab/leakfix later to maint).
124 * Plug various memory leaks in test-tool commands.
125 (merge f40a693450 ab/test-tool-leakfix later to maint).
127 * Fixes a long-standing corner case bug around directory renames in
128 the merge-ort strategy.
130 * The resolve-undo information in the index was not protected against
131 GC, which has been corrected.
132 (merge e0ad13977a jc/resolve-undo later to maint).
134 * A corner case bug where lazily fetching objects from a promisor
135 remote resulted in infinite recursion has been corrected.
136 (merge cb88b37cb9 hx/lookup-commit-in-graph-fix later to maint).
138 * "git clone" from a repository with some ref whose HEAD is unborn
139 did not set the HEAD in the resulting repository correctly, which
140 has been corrected.
141 (merge daf7898abb jk/clone-unborn-confusion later to maint).
143 * An earlier attempt to plug leaks placed a clean-up label to jump to
144 at a bogus place, which as been corrected.
146 * Variable quoting fix in the vimdiff driver of "git mergetool"
148 * "git shortlog -n" relied on the underlying qsort() to be stable,
149 which shouldn't have. Fixed.
151 * A fix for a regression in test framework.
153 * mkstemp() emulation on Windows has been improved.
154 (merge ae25974de3 rs/mingw-tighten-mkstemp later to maint).
156 * Add missing documentation for "include" and "includeIf" features in
157 "git config" file format, which incidentally teaches the command
158 line completion to include them in its offerings.
159 (merge 07aed58017 mb/config-document-include later to maint).
161 * Avoid "white/black-list" in documentation and code comments.
162 (merge f5adaa5cc3 ds/doc-wo-whitelist later to maint).
164 * Workaround for a compiler warning against use of die() in
165 osx-keychain (in contrib/).
166 (merge f2fc531585 ld/osx-keychain-usage-fix later to maint).
168 * Workaround for a false positive compiler warning.
169 (merge b4f52f09ae ds/win-syslog-compiler-fix later to maint).
171 * "git p4" working on UTF-16 files on Windows did not implement
172 CRLF-to-LF conversion correctly, which has been corrected.
173 (merge 4d35f74421 mb/p4-utf16-crlf later to maint).
175 * "git p4" did not handle non-ASCII client name well, which has been
176 corrected.
177 (merge d205483695 kk/p4-client-name-encoding-fix later to maint).
179 * "rerere-train" script (in contrib/) used to honor commit.gpgSign
180 while recreating the throw-away merges.
181 (merge cc391fc886 cl/rerere-train-with-no-sign later to maint).
183 * "git checkout" miscounted the paths it updated, which has been
184 corrected.

187 * Other code cleanup, docfix, build fix, etc.
188 (merge a700395eaf ma/t4200-update later to maint).
