1 Git v2.9.1 Release Notes
2 ========================
7 * When "git daemon" is run without --[init-]timeout specified, a
8 connection from a client that silently goes offline can hang around
9 for a long time, wasting resources. The socket-level KEEPALIVE has
10 been enabled to allow the OS to notice such failed connections.
12 * The commands in `git log` family take %C(auto) in a custom format
13 string. This unconditionally turned the color on, ignoring
14 --no-color or with --color=auto when the output is not connected to
15 a tty; this was corrected to make the format truly behave as
18 * "git rev-list --count" whose walk-length is limited with "-n"
19 option did not work well with the counting optimized to look at the
22 * "git show -W" (extend hunks to cover the entire function, delimited
23 by lines that match the "funcname" pattern) used to show the entire
24 file when a change added an entire function at the end of the file,
27 * The documentation set has been updated so that literal commands,
28 configuration variables and environment variables are consistently
29 typeset in fixed-width font and bold in manpages.
31 * "git svn propset" subcommand that was added in 2.3 days is
34 * The documentation tries to consistently spell "GPG"; when
35 referring to the specific program name, "gpg" is used.
37 * "git reflog" stopped upon seeing an entry that denotes a branch
38 creation event (aka "unborn"), which made it appear as if the
41 * The git-prompt scriptlet (in contrib/) was not friendly with those
42 who uses "set -u", which has been fixed.
44 * A codepath that used alloca(3) to place an unbounded amount of data
45 on the stack has been updated to avoid doing so.
47 * "git update-index --add --chmod=+x file" may be usable as an escape
48 hatch, but not a friendly thing to force for people who do need to
49 use it regularly. "git add --chmod=+x file" can be used instead.
51 * Build improvements for gnome-keyring (in contrib/)
53 * "git status" used to say "working directory" when it meant "working
56 * Comments about misbehaving FreeBSD shells have been clarified with
57 the version number (9.x and before are broken, newer ones are OK).
59 * "git cherry-pick A" worked on an unborn branch, but "git
60 cherry-pick A..B" didn't.
62 * "git add -i/-p" learned to honor diff.compactionHeuristic
63 experimental knob, so that the user can work on the same hunk split
66 * "log --graph --format=" learned that "%>|(N)" specifies the width
67 relative to the terminal's left edge, not relative to the area to
68 draw text that is to the right of the ancestry-graph section. It
69 also now accepts negative N that means the column limit is relative
72 * The ownership rule for the piece of memory that hold references to
73 be fetched in "git fetch" was screwy, which has been cleaned up.
75 * "git bisect" makes an internal call to "git diff-tree" when
76 bisection finds the culprit, but this call did not initialize the
77 data structure to pass to the diff-tree API correctly.
79 * Formats of the various data (and how to validate them) where we use
80 GPG signature have been documented.
82 * Fix an unintended regression in v2.9 that breaks "clone --depth"
83 that recurses down to submodules by forcing the submodules to also
84 be cloned shallowly, which many server instances that host upstream
85 of the submodules are not prepared for.
87 * Fix unnecessarily waste in the idiomatic use of ': ${VAR=default}'
88 to set the default value, without enclosing it in double quotes.
90 * Some platform-specific code had non-ANSI strict declarations of C
91 functions that do not take any parameters, which has been
94 * The internal code used to show local timezone offset is not
95 prepared to handle timestamps beyond year 2100, and gave a
96 bogus offset value to the caller. Use a more benign looking
97 +0000 instead and let "git log" going in such a case, instead
100 * One among four invocations of readlink(1) in our test suite has
101 been rewritten so that the test can run on systems without the
102 command (others are in valgrind test framework and t9802).
104 * t/perf needs /usr/bin/time with GNU extension; the invocation of it
105 is updated to "gtime" on Darwin.
107 * A bug, which caused "git p4" while running under verbose mode to
108 report paths that are omitted due to branch prefix incorrectly, has
109 been fixed; the command said "Ignoring file outside of prefix" for
110 paths that are _inside_.
112 * The top level documentation "git help git" still pointed at the
113 documentation set hosted at now-defunct google-code repository.
114 Update it to point to https://git.github.io/htmldocs/git.html
117 Also contains minor documentation updates and code clean-ups.
