1Git v1.7.12 Release Notes 2========================= 3 4Updates since v1.7.11 5--------------------- 6 7UI, Workflows & Features 8 9 * Git can be told to normalize pathnames it read from readdir(3) and 10 all arguments it got from the command line into precomposed UTF-8 11 (assuming that they come as decomposed UTF-8), in order to work 12 around issues on Mac OS. 13 14 I think there still are other places that need conversion 15 (e.g. paths that are read from stdin for some commands), but this 16 should be a good first step in the right direction. 17 18 * Per-user $HOME/.gitconfig file can optionally be stored in 19 $HOME/.config/git/config instead, which is in line with XDG. 20 21 * The value of core.attributesfile and core.excludesfile default to 22 $HOME/.config/git/attributes and $HOME/.config/git/ignore respectively 23 when these files exist. 24 25 * Logic to disambiguate abbreviated object names have been taught to 26 take advantage of object types that are expected in the context, 27 e.g. XXXXXX in the "git describe" output v1.2.3-gXXXXXX must be a 28 commit object, not a blob nor a tree. This will help us prolong 29 the lifetime of abbreviated object names. 30 31 * "git apply" learned to wiggle the base version and perform three-way 32 merge when a patch does not exactly apply to the version you have. 33 34 * Scripted Porcelain writers now have access to the credential API via 35 the "git credential" plumbing command. 36 37 * "git help" used to always default to "man" format even on platforms 38 where "man" viewer is not widely available. 39 40 * "git clone --local $path" started its life as an experiment to 41 optionally use link/copy when cloning a repository on the disk, but 42 we didn't deprecate it after we made the option a no-op to always 43 use the optimization. The command learned "--no-local" option to 44 turn this off, as a more explicit alternative over use of file:// 45 URL. 46 47 * "git fetch" and friends used to say "remote side hung up 48 unexpectedly" when they failed to get response they expect from the 49 other side, but one common reason why they don't get expected 50 response is that the remote repository does not exist or cannot be 51 read. The error message in this case was updated to give better 52 hints to the user. 53 54 * git native protocol agents learned to show software version over 55 the wire, so that the server log can be examined to see the vintage 56 distribution of clients. 57 58 * "git help -w $cmd" can show HTML version of documentation for 59 "git-$cmd" by setting help.htmlpath to somewhere other than the 60 default location where the build procedure installs them locally; 61 the variable can even point at a http:// URL. 62 63 * "git rebase [-i] --root $tip" can now be used to rewrite all the 64 history leading to "$tip" down to the root commit. 65 66 * "git rebase -i" learned "-x <cmd>" to insert "exec <cmd>" after 67 each commit in the resulting history. 68 69 * "git status" gives finer classification to various states of paths 70 in conflicted state and offer advice messages in its output. 71 72 * "git submodule" learned to deal with nested submodule structure 73 where a module is contained within a module whose origin is 74 specified as a relative URL to its superproject's origin. 75 76 * A rather heavy-ish "git completion" script has been split to create 77 a separate "git prompting" script, to help lazy-autoloading of the 78 completion part while making prompting part always available. 79 80 * "gitweb" pays attention to various forms of credits that are 81 similar to "Signed-off-by:" lines in the commit objects and 82 highlights them accordingly. 83 84 85Foreign Interface 86 87 * "mediawiki" remote helper (in contrib/) learned to handle file 88 attachments. 89 90 * "git p4" now uses "Jobs:" and "p4 move" when appropriate. 91 92 * vcs-svn has been updated to clean-up compilation, lift 32-bit 93 limitations, etc. 94 95 96Performance, Internal Implementation, etc. (please report possible regressions) 97 98 * Some tests showed false failures caused by a bug in ecryptofs. 99 100 * We no longer use AsciiDoc7 syntax in our documentation and favor a 101 more modern style. 102 103 * "git am --rebasing" codepath was taught to grab authorship, log 104 message and the patch text directly out of existing commits. This 105 will help rebasing commits that have confusing "diff" output in 106 their log messages. 107 108 * "git index-pack" and "git pack-objects" use streaming API to read 109 from the object store to avoid having to hold a large blob object 110 in-core while they are doing their thing. 111 112 * Code to match paths with exclude patterns learned to avoid calling 113 fnmatch() by comparing fixed leading substring literally when 114 possible. 115 116 * "git log -n 1 -- rarely-touched-path" was spending unnecessary 117 cycles after showing the first change to find the next one, only to 118 discard it. 119 120 * "git svn" got a large-looking code reorganization at the last 121 minute before the code freeze. 122 123Also contains minor documentation updates and code clean-ups. 124 125 126Fixes since v1.7.11 127------------------- 128 129Unless otherwise noted, all the fixes since v1.7.11 in the maintenance 130releases are contained in this release (see release notes to them for 131details). 132 133 * "git grep" stopped spawning an external "grep" long time ago, but a 134 duplicated test to check internal and external "grep" was left 135 behind. 136 (merge 4ca9453 rj/maint-grep-remove-redundant-test later to maint). 137 138 * The code to avoid mistaken attempt to add the object directory 139 itself as its own alternate could read beyond end of a string while 140 comparison. 141 (merge cb2912c hv/link-alt-odb-entry later to maint). 142 143 * "git checkout <branchname>" to come back from a detached HEAD state 144 incorrectly computed reachability of the detached HEAD, resulting 145 in unnecessary warnings. 146 (merge add416a jk/maint-checkout-orphan-check-fix later to maint). 147 148 * The documentation for revision range specifiers (e.g. A..B, A^@) 149 has been updated. 150 (merge ca5ee2d mh/maint-revisions-doc later to maint). 151 152 * "git submodule add" was confused when the superproject did not have 153 its repository in its usual place in the working tree and GIT_DIR 154 and GIT_WORK_TREE was used to access it. 155 156 * "git mergetool" did not support --tool-help option to give the list 157 of supported backends, like "git difftool" does. 158 (merge 109859e jc/mergetool-tool-help later to maint). 159 160 * "git commit --amend" let the user edit the log message and then died 161 when the human-readable committer name was given insufficiently by 162 getpwent(3).
