1GIT v1.5.3 Release Notes 2======================== 3 4Updates since v1.5.2 5-------------------- 6 7* The commit walkers other than http are officially deprecated, 8 but still supported for now. 9 10* The submodule support has Porcelain layer. 11 12* There are a handful pack-objects changes to help you cope better 13 with repositories with pathologically large blobs in them. 14 15* For people who need to import from Perforce, a front-end for 16 fast-import is in contrib/fast-import/. 17 18* Comes with git-gui 0.8.0. 19 20* Comes with updated gitk. 21 22* New commands and options. 23 24 - "git log --date=<format>" can use more formats: iso8601, rfc2822. 25 26 - The hunk header output from "git diff" family can be customized 27 with the attributes mechanism. See gitattributes(5) for details. 28 29 - "git stash" allows you to quickly save away your work in 30 progress and replay it later on an updated state. 31 32 - "git rebase" learned an "interactive" mode that let you 33 pick and reorder which commits to rebuild. 34 35 - "git fsck" can save its findings in $GIT_DIR/lost-found, 36 without a separate invocation of "git lost-found" command. 37 38 - $GIT_WORK_TREE environment variable can be used together with 39 $GIT_DIR to work in a subdirectory of a working tree that is 40 not located at "$GIT_DIR/..". 41 42 - "git log" learned a new option "--follow", to follow 43 renaming history of a single file. 44 45 - "git-filter-branch" lets you rewrite the revision history of 46 the current branch, creating a new branch. You can specify a 47 number of filters to modify the commits, files and trees. 48 49 - "git-cvsserver" learned new options (--base-path, --export-all, 50 --strict-paths) inspired by git-daemon. 51 52 - "git-submodule" command helps you manage the projects from 53 the superproject that contain them. 54 55 - In addition to core.compression configuration option, 56 core.loosecompression and pack.compression options can 57 independently tweak zlib compression levels used for loose 58 and packed objects. 59 60 - "git-ls-tree -l" shows size of blobs pointed at by the 61 tree entries, similar to "/bin/ls -l". 62 63 - "git-rev-list" learned --regexp-ignore-case and 64 --extended-regexp options to tweak its matching logic used 65 for --grep fitering. 66 67 - "git-describe --contains" is a handier way to call more 68 obscure command "git-name-rev --tags". 69 70 - "git gc --aggressive" tells the command to spend more cycles 71 to optimize the repository harder. 72 73 - "git repack" learned a "window-memory" limit which 74 dynamically reduces the window size to stay within the 75 specified memory usage. 76 77 - "git repack" can be told to split resulting packs to avoid 78 exceeding limit specified with "--max-pack-size". 79 80 - "git fsck" gained --verbose option. This is really really 81 verbose but it might help you identify exact commit that is 82 corrupt in your repository. 83 84 - "git format-patch" learned --numbered-files option. This 85 may be useful for MH users. 86 87 - "git format-patch" learned format.subjectprefix configuration 88 variable, which serves the same purpose as "--subject-prefix" 89 option. 90 91 - "git tag -n -l" shows tag annotations while listing tags. 92 93 - "git cvsimport" can optionally use the separate-remote layout. 94 95 - "git blame" can be told to see through commits that change 96 whitespaces and indentation levels with "-w" option. 97 98 - "git send-email" can be told not to thread the messages when 99 sending out more than one patches. 100 101 - "git config" learned NUL terminated output format via -z to 102 help scripts. 103 104 - "git init -q" makes the command quieter. 105 106* Updated behavior of existing commands. 107 108 - "git rm --cached" does not complain when removing a newly 109 added file from the index anymore. 110 111 - "git svn dcommit" retains local merge information. 112 113 - "git config" to set values also honors type flags like --bool 114 and --int. 115 116 - core.quotepath configuration can be used to make textual git 117 output to emit most of the characters in the path literally. 118 119 - "git mergetool" chooses its backend more wisely, taking 120 notice of its environment such as use of X, Gnome/KDE, etc. 121 122 - "gitweb" shows merge commits a lot nicer than before. The 123 default view uses more compact --cc format, while the UI 124 allows to choose normal diff with any parent. 125 126 - snapshot files "gitweb" creates from a repository at 127 $path/$project/.git are more useful. We use $project part 128 in the filename, which we used to discard. 129 130 - "git cvsimport" creates lightweight tags; there is no 131 interesting information we can record in an annotated tag, 132 and the handcrafted ones the old code created was not 133 properly formed anyway. 134 135 - "git-push" pretends that you immediately fetched back from 136 the remote by updating corresponding remote tracking 137 branches if you have any. 138 139 - The diffstat given after a merge (or a pull) honors the 140 color.diff configuration. 141 142 - "git-apply --whitespace=strip" removes blank lines added at 143 the end of the file. 144 145 - "git-fetch" over git native protocols with "-v" option shows 146 connection status, and the IP address of the other end, to 147 help diagnosing problems. 148 149 - We used to have core.legacyheaders configuration, when 150 set to false, allowed git to write loose objects in a format 151 that mimicks the format used by objects stored in packs. It 152 turns out that this was not so useful. Although we will 153 continue to read objects written in that format, we do not 154 honor that configuration anymore and create loose objects in 155 the legacy/traditional format. 156 157 - "--find-copies-harder" option to diff family can now be 158 spelled as "-C -C" for brevity. 159 160 - "git-mailsplit" (hence "git-am") can read from Maildir 161 formatted mailboxes. 162 163 - "git-cvsserver" does not barf upon seeing "cvs login" 164 request. 165 166 - "pack-objects" honors "delta" attribute set in 167 .gitattributes. It does not attempt to deltify blobs that 168 come from paths with delta attribute set to false. 169 170 - "new-workdir" script (in contrib) can now be used with a 171 bare repository. 172 173 - "git-mergetool" learned to use gvimdiff. 174 175 - "gitview" (in contrib) has a better blame interface. 176 177 - "git log" and friends did not handle a commit log message 178 that is larger than 16kB; they do now. 179 180 - "--pretty=oneline" output format for "git log" and friends 181 deals with "malformed" commit log messages that have more 182 than one lines in the first paragraph better. We used to 183 show the first line, cutting the title at mid-sentence; we 184 concatenate them into a single line and treat the result as 185 "oneline". 186 187 - "git p4import" has been demoted to contrib status. For 188 a superior option, checkout the git-p4 front end to 189 git-fast-import (also in contrib). The man page and p4 190 rpm have been removed as well. 191 192* Builds 193 194 - old-style function definitions (most notably, a function 195 without parameter defined with "func()", not "func(void)") 196 have been eradicated. 197 198* Performance Tweaks 199 200 - git-pack-objects avoids re-deltification cost by caching 201 small enough delta results it creates while looking for the 202 best delta candidates. 203 204 - git-pack-objects learned a new heuristcs to prefer delta 205 that is shallower in depth over the smallest delta 206 possible. This improves both overall packfile access 207 performance and packfile density. 208 209 - diff-delta code that is used for packing has been improved 210 to work better on big files. 211 212 - when there are more than one pack files in the repository, 213 the runtime used to try finding an object always from the 214 newest packfile; it now tries the same packfile as we found 215 the object requested the last time, which exploits the 216 locality of references. 217 218 - verifying pack contents done by "git fsck --full" got boost 219 by carefully choosing the order to verify objects in them. 220 221 222Fixes since v1.5.2 223------------------ 224 225All of the fixes in v1.5.2 maintenance series are included in 226this release, unless otherwise noted. 227 228* Bugfixes 229 230 - "gitweb" had trouble handling non UTF-8 text with older 231 Encode.pm Perl module. 232 233-- 234exec >/var/tmp/1 235O=v1.5.3-rc2 236echo O=`git describe refs/heads/master` 237git shortlog --no-merges $O..refs/heads/master ^refs/heads/maint
