1GIT v1.6.5 Release Notes 2======================== 3 4In git 1.7.0, which was planned to be the release after 1.6.5, "git 5push" into a branch that is currently checked out will be refused by 6default. 7 8You can choose what should happen upon such a push by setting the 9configuration variable receive.denyCurrentBranch in the receiving 10repository. 11 12Also, "git push $there :$killed" to delete the branch $killed in a remote 13repository $there, when $killed branch is the current branch pointed at by 14its HEAD, will be refused by default. 15 16You can choose what should happen upon such a push by setting the 17configuration variable receive.denyDeleteCurrent in the receiving 18repository. 19 20To ease the transition plan, the receiving repository of such a 21push running this release will issue a big warning when the 22configuration variable is missing. Please refer to: 23 24 http://git.or.cz/gitwiki/GitFaq#non-bare 25 http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007 26 27for more details on the reason why this change is needed and the 28transition plan. 29 30Updates since v1.6.4 31-------------------- 32 33(subsystems) 34 35 * various updates to gitk, git-svn and gitweb. 36 37(portability) 38 39 * more improvements on mingw port. 40 41 * mingw will also give FRSX as the default value for the LESS 42 environment variable when the user does not have one. 43 44 * initial support to compile git on Windows with MSVC. 45 46(performance) 47 48 * On major platforms, the system can be compiled to use with Linus's 49 block-sha1 implementation of the SHA-1 hash algorithm, which 50 outperforms the default fallback implementation we borrowed from 51 Mozilla. 52 53 * Unnecessary inefficiency in deepening of a shallow repository has 54 been removed. 55 56 * "git clone" does not grab objects that it does not need (i.e. 57 referenced only from refs outside refs/heads and refs/tags 58 hierarchy) anymore. 59 60 * The "git" main binary used to link with libcurl, which then dragged 61 in a large number of external libraries. When using basic plumbing 62 commands in scripts, this unnecessarily slowed things down. We now 63 implement http/https/ftp transfer as a separate executable as we 64 used to. 65 66 * "git clone" run locally hardlinks or copies the files in .git/ to 67 newly created repository. It used to give new mtime to copied files, 68 but this delayed garbage collection to trigger unnecessarily in the 69 cloned repository. We now preserve mtime for these files to avoid 70 this issue. 71 72(usability, bells and whistles) 73 74 * Human writable date format to various options, e.g. --since=yesterday, 75 master@{2000.09.17}, are taught to infer some omitted input properly. 76 77 * A few programs gave verbose "advice" messages to help uninitiated 78 people when issuing error messages. An infrastructure to allow 79 users to squelch them has been introduced, and a few such messages 80 can be silenced now. 81 82 * refs/replace/ hierarchy is designed to be usable as a replacement 83 of the "grafts" mechanism, with the added advantage that it can be 84 transferred across repositories. 85 86 * "git am" learned to optionally ignore whitespace differences. 87 88 * "git am" handles input e-mail files that has CRLF line endings sensibly. 89 90 * "git am" learned "--scissors" option to allow you to discard early part 91 of an incoming e-mail. 92 93 * "git archive -o output.zip" works without being told what format to 94 use with an explicit "--format=zip".option. 95 96 * "git checkout", "git reset" and "git stash" learned to pick and 97 choose to use selected changes you made, similar to "git add -p". 98 99 * "git clone" learned a "-b" option to pick a HEAD to check out 100 different from the remote's default branch. 101 102 * "git clone" learned --recursive option. 103 104 * "git clone" from a local repository on a different filesystem used to 105 copy individual object files without preserving the old timestamp, giving 106 them extra lifetime in the new repository until they gc'ed. 107 108 * "git commit --dry-run $args" is a new recommended way to ask "what would 109 happen if I try to commit with these arguments." 110 111 * "git commit --dry-run" and "git status" shows conflicted paths in a 112 separate section to make them easier to spot during a merge. 113 114 * "git cvsimport" now supports password-protected pserver access even 115 when the password is not taken from ~/.cvspass file. 116 117 * "git fast-export" learned --no-data option that can be useful when 118 reordering commits and trees without touching the contents of 119 blobs. 120 121 * "git fast-import" has a pair of new front-end in contrib/ area. 122 123 * "git init" learned to mkdir/chdir into a directory when given an 124 extra argument (i.e. "git init this"). 125 126 * "git instaweb" optionally can use mongoose as the web server. 127 128 * "git log --decorate" can optionally be told with --decorate=full to 129 give the reference name in full. 130 131 * "git merge" issued an unnecessarily scary message when it detected 132 that the merge may have to touch the path that the user has local 133 uncommitted changes to. The message has been reworded to make it 134 clear that the command aborted, without doing any harm. 135 136 * "git push" can be told to be --quiet. 137 138 * "git push" pays attention to url.$base.pushInsteadOf and uses a URL 139 that is derived from the URL used for fetching. 140 141 * informational output from "git reset" that lists the locally modified 142 paths is made consistent with that of "git checkout $another_branch". 143 144 * "git submodule" learned to give submodule name to scripts run with 145 "foreach" subcommand. 146 147 * various subcommands to "git submodule" learned --recursive option. 148 149 * "git submodule summary" learned --files option to compare the work 150 tree vs the commit bound at submodule path, instead of comparing 151 the index. 152 153 * "git upload-pack", which is the server side support for "git clone" and 154 "git fetch", can call a new post-upload-pack hook for statistics purposes. 155 156(developers) 157 158 * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the 159 source directory; using tmpfs may give faster turnaround. 160 161 * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can 162 build for one location, and install into another location to tar it 163 up. 164 165Fixes since v1.6.4 166------------------ 167 168All of the fixes in v1.6.4.X maintenance series are included in this 169release, unless otherwise noted.
