9 * Building on older MacOS X systems automatically sets
10 the necessary NO_APPLE_COMMON_CRYPTO build-time option.
13 UI, Workflows & Features
15 * "git config --edit --global" starts from a skeletal per-user
16 configuration file contents, instead of a total blank, when the
17 user does not already have any. This immediately reduces the
18 need for a later "Have you forgotten setting core.user?" and we
19 can add more to the template as we gain more experience.
21 * "git stash list -p" used to be almost always a no-op because each
22 stash entry is represented as a merge commit. It learned to show
23 the difference between the base commit version and the working tree
24 version, which is in line with what "git show" gives.
26 Performance, Internal Implementation, etc.
28 * The API to manipulate the "refs" is currently undergoing a revamp
29 to make it more transactional, with the eventual goal to allow
30 all-or-none atomic updates and migrating the storage to something
31 other than the traditional filesystem based one (e.g. databases).
33 * We no longer attempt to keep track of individual dependencies to
34 the header files in the build procedure, relying on automated
35 dependency generation support from modern compilers.
37 * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites
38 long before negated prerequisites e.g. !MINGW were invented.
39 The former has been converted to the latter to avoid confusion.
41 * Looking up remotes configuration in a repository with very many
42 remotes defined has been optimized.
44 * There are cases where you lock and open to write a file, close it
45 to show the updated contents to external processes, and then have
46 to update the file again while still holding the lock, but the
47 lockfile API lacked support for such an access pattern.
49 * The API to allocate the structure to keep track of commit
50 decoration has been updated to make it less cumbersome to use.
52 * An in-core caching layer to let us avoid reading the same
53 configuration files number of times has been added. A few commands
54 have been converted to use this subsystem.
56 * Various code paths have been cleaned up and simplified by using
57 "strbuf", "starts_with()", and "skip_prefix()" APIs more.
59 * A few codepaths that died when large blobs that would not fit in
60 core are involved in their operation have been taught to punt
61 instead, by e.g. marking too large a blob as not to be diffed.
63 * A few more code paths in "commit" and "checkout" have been taught
64 to repopulate the cache-tree in the index, to help speed up later
65 "write-tree" (used in "commit") and "diff-index --cached" (used in
69 Also contains various documentation updates and code clean-ups.
75 Unless otherwise noted, all the fixes since v2.1 in the maintenance
76 track are contained in this release (see the maintenance releases'
79 * "git log --pretty/format=" with an empty format string did not
80 mean the more obvious "No output whatsoever" but "Use default
81 format", which was counterintuitive.
82 (merge b9c7d6e jk/pretty-empty-format later to maint).
84 * Implementations of "tar" that do not understand an extended pax
85 header would extract the contents of it in a regular file; make
86 sure the permission bits of this file follows the same tar.umask
87 configuration setting.
89 * "git -c section.var command" and "git -c section.var= command"
90 should pass the configuration differently (the former should be a
91 boolean true, the latter should be an empty string).
92 (merge a789ca7 jk/command-line-config-empty-string later to maint).
94 * Applying a patch not generated by Git in a subdirectory used to
95 check the whitespace breakage using the attributes for incorrect
96 paths. Also whitespace checks were performed even for paths
97 excluded via "git apply --exclude=<path>" mechanism.
98 (merge 477a08a jc/apply-ws-prefix later to maint).
100 * "git bundle create" with date-range specification were meant to
101 exclude tags outside the range, but it didn't.
102 (merge 2c8544a lf/bundle-exclusion later to maint).
104 * "git add x" where x that used to be a directory has become a
105 symbolic link to a directory misbehaved.
106 (merge ccad42d rs/refresh-beyond-symlink later to maint).
108 * The prompt script checked $GIT_DIR/ref/stash file to see if there
109 is a stash, which was a no-no.
110 (merge 0fa7f01 jk/prompt-stash-could-be-packed later to maint).
112 * Pack-protocol documentation had a minor typo.
113 (merge 5d146f7 sp/pack-protocol-doc-on-shallow later to maint).
115 * "git checkout -m" did not switch to another branch while carrying
116 the local changes forward when a path was deleted from the index.
117 (merge 6a143aa jn/unpack-trees-checkout-m-carry-deletion later to maint).
119 * With sufficiently long refnames, "git fast-import" could have
120 overflown an on-stack buffer.
121 (merge c252785 jk/fast-import-fixes later to maint).
123 * After "pack-refs --prune" packed refs at the top-level, it failed
125 (merge afd11d3 jk/prune-top-level-refs-after-packing later to maint).
127 * Progress output from "git gc --auto" was visible in "git fetch -q".
128 (merge 6fceed3 nd/fetch-pass-quiet-to-gc-child-process later to maint).
130 * We used to pass -1000 to poll(2), expecting it to also mean "no
131 timeout", which should be spelled as -1.
132 (merge 6c71f8b et/spell-poll-infinite-with-minus-one-only later to maint).
