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/attributes and $HOME/.config/ignore respectively when 23 these files exist. 24 25 * "git apply" learned to wiggle the base version and perform three-way 26 merge when a patch does not exactly apply to the version you have. 27 28 * Scripted Porcelain writers now have access to the credential API via 29 the "git credential" plumbing command. 30 31 * "git help" used to always default to "man" format even on platforms 32 where "man" viewer is not widely available. 33 34 * "git clone --local $path" started its life as an experiment to 35 optionally use link/copy when cloning a repository on the disk, but 36 we didn't deprecate it after we made the option a no-op to always 37 use the optimization. The command learned "--no-local" option to 38 turn this off, as a more explicit alternative over use of file:// 39 URL. 40 41 * "git fetch" and friends used to say "remote side hung up 42 unexpectedly" when they failed to get response they expect from the 43 other side, but one common reason why they don't get expected 44 response is that the remote repository does not exist or cannot be 45 read. The error message in this case was updated to give better 46 hints to the user. 47 48 * git native protocol agents learned to show software version over 49 the wire, so that the server log can be examined to see the vintage 50 distribution of clients. 51 52 * "git help -w $cmd" can show HTML version of documentation for 53 "git-$cmd" by setting help.htmlpath to somewhere other than the 54 default location where the build procedure installs them locally; 55 the variable can even point at a http:// URL. 56 57 * "git rebase [-i] --root $tip" can now be used to rewrite all the 58 history leading to "$tip" down to the root commit. 59 60 * "git rebase -i" learned "-x <cmd>" to insert "exec <cmd>" after 61 each commit in the resulting history. 62 63 * "git status" gives finer classification to various states of paths 64 in conflicted state and offer advice messages in its output. 65 66 * "git submodule" learned to deal with nested submodule structure 67 where a module is contained within a module whose origin is 68 specified as a relative URL to its superproject's origin. 69 70 * A rather heavy-ish "git completion" script has been split to create 71 a separate "git prompting" script, to help lazy-autoloading of the 72 completion part while making prompting part always available. 73 74 75Foreign Interface 76 77 * "mediawiki" remote helper (in contrib/) learned to handle file 78 attachments. 79 80 * "git p4" now uses "Jobs:" and "p4 move" when appropriate. 81 82 * vcs-svn has been updated to clean-up compilation, lift 32-bit 83 limitations, etc. 84 85 86Performance, Internal Implementation, etc. (please report possible regressions) 87 88 * Some tests showed false failures caused by a bug in ecryptofs. 89 90 * We no longer use AsciiDoc7 syntax in our documentation and favor a 91 more modern style. 92 93 * "git am --rebasing" codepath was taught to grab authorship, log 94 message and the patch text directly out of existing commits. This 95 will help rebasing commits that have confusing "diff" output in 96 their log messages. 97 98 * "git index-pack" and "git pack-objects" use streaming API to read 99 from the object store to avoid having to hold a large blob object 100 in-core while they are doing their thing. 101 102 * Code to match paths with exclude patterns learned to avoid calling 103 fnmatch() by comparing fixed leading substring literally when 104 possible. 105 106 107Also contains minor documentation updates and code clean-ups. 108 109 110Fixes since v1.7.11 111------------------- 112 113Unless otherwise noted, all the fixes since v1.7.11 in the maintenance 114releases are contained in this release (see release notes to them for 115details). 116 117 * The error message from "git push $there :bogo" (and its equivalent 118 "git push $there --delete bogo") mentioned that we tried and failed 119 to guess what ref is being deleted based on the LHS of the refspec, 120 which we don't. 121 (merge 5742c82 jk/push-delete-ref-error-message later to maint). 122 123 * A handful of files and directories we create had tighter than 124 necessary permission bits when the user wanted to have group 125 writability (e.g. by setting "umask 002"). 126 (merge 6ff2b72 ar/clone-honor-umask-at-top later to maint). 127 128 * "commit --amend" used to refuse amending a commit with an empty log 129 message, with or without "--allow-empty-message". 130 (merge d9a9357 cw/amend-commit-without-message later to maint). 131 132 * "git commit --amend --only --" was meant to allow "Clever" people to 133 rewrite the commit message without making any change even when they 134 have already changes for the next commit added to their index, but 135 it never worked as advertised since it was introduced in 1.3.0 era. 136 (merge ea2d4ed jk/maint-commit-amend-only-no-paths later to maint). 137 138 * Even though the index can record pathnames longer than 1<<12 bytes, 139 in some places we were not comparing them in full, potentially 140 replacing index entries instead of adding. 141 (merge d5f5333 tg/maint-cache-name-compare later to maint). 142 143 * "git show"'s auto-walking behaviour was an unreliable and 144 unpredictable hack; it now behaves just like "git log" does when it 145 walks. 146 (merge c5941f1 tr/maint-show-walk later to maint). 147 148 * "git diff", "git status" and anything that internally uses the 149 comparison machinery was utterly broken when the difference 150 involved a file with "-" as its name. This was due to the way "git 151 diff --no-index" was incorrectly bolted on to the system, making 152 any comparison that involves a file "-" at the root level 153 incorrectly read from the standard input. 154 (merge 4682d85 jc/refactor-diff-stdin later to maint). 155 156 * We did not have test to make sure "git rebase" without extra options 157 filters out an empty commit in the original history. 158 (merge 2b5ba7b mz/empty-rebase-test later to maint). 159 160 * "git fast-export" produced an input stream for fast-import without 161 properly quoting pathnames when they contain SPs in them. 162 (merge ff59f6d js/fast-export-paths-with-spaces later to maint). 163 164 * "git checkout --detach", when you are still on an unborn branch, 165 should be forbidden, but it wasn't. 166 (merge 8ced1aa cw/no-detaching-an-unborn later to maint). 167 168 * Some implementations of Perl terminates "lines" with CRLF even when 169 the script is operating on just a sequence of bytes. Make sure to 170 use "$PERL_PATH", the version of Perl the user told Git to use, in 171 our tests to avoid unnecessary breakages in tests. 172 (merge ad78585 vr/use-our-perl-in-tests later to maint).
