1 Git 2.6 Release Notes
2 =====================
4 Updates since v2.5
5 ------------------
7 UI, Workflows & Features
9 * An asterisk as a substring (as opposed to the entirety) of a path
10 component for both side of a refspec, e.g.
11 "refs/heads/o*:refs/remotes/heads/i*", is now allowed.
13 * New userdiff pattern definition for fountain screenwriting markup
14 format has been added.
16 * "git log" and friends learned a new "--date=format:..." option to
17 format timestamps using system's strftime(3).
19 * "git fast-import" learned to respond to the get-mark command via
20 its cat-blob-fd interface.
22 * "git rebase -i" learned "drop commit-object-name subject" command
23 as another way to skip replaying of a commit.
25 * A new configuration variable can enable "--follow" automatically
26 when "git log" is run with one pathspec argument.
28 * "git status" learned to show a more detailed information regarding
29 the "rebase -i" session in progress.
31 * "git cat-file" learned "--batch-all-objects" option to enumerate all
32 available objects in the repository more quickly than "rev-list
33 --all --objects" (the output includes unreachable objects, though).
35 * "git fsck" learned to ignore errors on a set of known-to-be-bad
36 objects, and also allows the warning levels of various kinds of
37 non-critical breakages to be tweaked.
39 * "git rebase -i"'s list of todo is made configurable.
41 * "git send-email" now performs alias-expansion on names that are
42 given via --cccmd, etc.
44 * An environment variable GIT_REPLACE_REF_BASE tells Git to look into
45 refs hierarchy other than refs/replace/ for the object replacement
46 data.
49 Performance, Internal Implementation, Development Support etc.
51 * In preparation for allowing different "backends" to store the refs
52 in a way different from the traditional "one ref per file in
53 $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage,
54 direct filesystem access to ref-like things like CHERRY_PICK_HEAD
55 from scripts and programs has been reduced.
57 * Computation of untracked status indicator by bash prompt
58 script (in contrib/) has been optimized.
60 * Memory use reduction when commit-slab facility is used to annotate
61 sparsely (which is not recommended in the first place).
63 * Clean up refs API and make "git clone" less intimate with the
64 implementation detail.
66 * "git pull" was reimplemented in C.
68 * The packet tracing machinery allows to capture an incoming pack
69 data to a file for debugging.
71 * Move machinery to parse human-readable scaled numbers like 1k, 4M,
72 and 2G as an option parameter's value from pack-objects to
73 parse-options API, to make it available to other codepaths.
75 * "git verify-tag" and "git verify-commit" have been taught to share
76 more code, and then learned to optionally show the verification
77 message from the underlying GPG implementation.
79 * Various enhancements around "git am" reading patches generated by
80 foreign SCM have been made.
82 * Ref listing by "git branch -l" and "git tag -l" commands has
83 started to be rebuilt, based on the for-each-ref machinery.
86 Also contains various documentation updates and code clean-ups.
89 Fixes since v2.5
90 ----------------
92 Unless otherwise noted, all the fixes since v2.5 in the maintenance
93 track are contained in this release (see the maintenance releases'
94 notes for details).
96 * "git subtree" (in contrib/) depended on "git log" output to be
97 stable, which was a no-no. Apply a workaround to force a
98 particular date format.
99 (merge e7aac44 da/subtree-date-confusion later to maint).
101 * An attempt to delete a ref by pushing into a repositorywhose HEAD
102 symbolic reference points at an unborn branch that cannot be
103 created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
104 points at refs/heads/a) failed.
105 (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint).
107 * The low-level "git send-pack" did not honor 'user.signingkey'
108 configuration variable when sending a signed-push.
109 (merge d830d39 db/send-pack-user-signingkey later to maint).
111 * "sparse checkout" misbehaved for a path that is excluded from the
112 checkout when switching between branches that differ at the path.
113 (merge 7d78241 as/sparse-checkout-removal later to maint).
115 * An experimental "untracked cache" feature used uname(2) in a
116 slightly unportable way.
117 (merge 100e433 cb/uname-in-untracked later to maint).
119 * A "rebase" replays changes of the local branch on top of something
120 else, as such they are placed in stage #3 and referred to as
121 "theirs", while the changes in the new base, typically a foreign
122 work, are placed in stage #2 and referred to as "ours". Clarify
123 the "checkout --ours/--theirs".
124 (merge f303016 se/doc-checkout-ours-theirs later to maint).
126 * The "rev-parse --parseopt" mode parsed the option specification
127 and the argument hint in a strange way to allow '=' and other
128 special characters in the option name while forbidding them from
129 the argument hint. This made it impossible to define an option
130 like "--pair <key>=<value>" with "pair=key=value" specification,
131 which instead would have defined a "--pair=key <value>" option.
132 (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint).
134 * Often a fast-import stream builds a new commit on top of the
135 previous commit it built, and it often unconditionally emits a
136 "from" command to specify the first parent, which can be omitted in
137 such a case. This caused fast-import to forget the tree of the
138 previous commit and then re-read it from scratch, which was
139 inefficient. Optimize for this common case.
140 (merge 0df3245 mh/fast-import-optimize-current-from later to maint).
142 * Running an aliased command from a subdirectory when the .git thing
143 in the working tree is a gitfile pointing elsewhere did not work.
144 (merge d95138e nd/export-worktree later to maint).
146 * "Is this subdirectory a separate repository that should not be
147 touched?" check "git clean" was inefficient. This was replaced
148 with a more optimized check.
149 (merge 38ae878 ee/clean-remove-dirs later to maint).
151 * Code cleanups and documentation updates.
152 (merge 1c601af es/doc-clean-outdated-tools later to maint).
153 (merge 3581304 kn/tag-doc-fix later to maint).
154 (merge 3a59e59 kb/i18n-doc later to maint).
