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 Note that the current submodule support is minimal and this is 13 deliberately so. A design decision we made is that operations 14 at the supermodule level do not recurse into submodules by 15 default. The expectation is that later we would add a 16 mechanism to tell git which submodules the user is interested 17 in, and this information might be used to determine the 18 recursive behaviour of certain commands (e.g. "git checkout" 19 and "git diff"), but currently we haven't agreed on what that 20 mechanism should look like. Therefore, if you use submodules, 21 you would probably need "git submodule update" on the 22 submodules you care about after running a "git checkout" at 23 the supermodule level. 24 25* There are a handful pack-objects changes to help you cope better 26 with repositories with pathologically large blobs in them. 27 28* For people who need to import from Perforce, a front-end for 29 fast-import is in contrib/fast-import/. 30 31* Comes with git-gui 0.8.2. 32 33* Comes with updated gitk. 34 35* New commands and options. 36 37 - "git log --date=<format>" can use more formats: iso8601, rfc2822. 38 39 - The hunk header output from "git diff" family can be customized 40 with the attributes mechanism. See gitattributes(5) for details. 41 42 - "git stash" allows you to quickly save away your work in 43 progress and replay it later on an updated state. 44 45 - "git rebase" learned an "interactive" mode that let you 46 pick and reorder which commits to rebuild. 47 48 - "git fsck" can save its findings in $GIT_DIR/lost-found, without a 49 separate invocation of "git lost-found" command. The blobs stored by 50 lost-found are stored in plain format to allow you to grep in them. 51 52 - $GIT_WORK_TREE environment variable can be used together with 53 $GIT_DIR to work in a subdirectory of a working tree that is 54 not located at "$GIT_DIR/..". 55 56 - Giving "--file=<file>" option to "git config" is the same as 57 running the command with GIT_CONFIG=<file> environment. 58 59 - "git log" learned a new option "--follow", to follow 60 renaming history of a single file. 61 62 - "git filter-branch" lets you rewrite the revision history of 63 specified branches. You can specify a number of filters to 64 modify the commits, files and trees. 65 66 - "git cvsserver" learned new options (--base-path, --export-all, 67 --strict-paths) inspired by "git daemon". 68 69 - "git daemon --base-path-relaxed" can help migrating a repository URL 70 that did not use to use --base-path to use --base-path. 71 72 - "git commit" can use "-t templatefile" option and commit.template 73 configuration variable to prime the commit message given to you in the 74 editor. 75 76 - "git submodule" command helps you manage the projects from 77 the superproject that contain them. 78 79 - In addition to core.compression configuration option, 80 core.loosecompression and pack.compression options can 81 independently tweak zlib compression levels used for loose 82 and packed objects. 83 84 - "git ls-tree -l" shows size of blobs pointed at by the 85 tree entries, similar to "/bin/ls -l". 86 87 - "git rev-list" learned --regexp-ignore-case and 88 --extended-regexp options to tweak its matching logic used 89 for --grep fitering. 90 91 - "git describe --contains" is a handier way to call more 92 obscure command "git name-rev --tags". 93 94 - "git gc --aggressive" tells the command to spend more cycles 95 to optimize the repository harder. 96 97 - "git repack" learned a "window-memory" limit which 98 dynamically reduces the window size to stay within the 99 specified memory usage. 100 101 - "git repack" can be told to split resulting packs to avoid 102 exceeding limit specified with "--max-pack-size". 103 104 - "git fsck" gained --verbose option. This is really really 105 verbose but it might help you identify exact commit that is 106 corrupt in your repository. 107 108 - "git format-patch" learned --numbered-files option. This 109 may be useful for MH users. 110 111 - "git format-patch" learned format.subjectprefix configuration 112 variable, which serves the same purpose as "--subject-prefix" 113 option. 114 115 - "git tag -n -l" shows tag annotations while listing tags. 116 117 - "git cvsimport" can optionally use the separate-remote layout. 118 119 - "git blame" can be told to see through commits that change 120 whitespaces and indentation levels with "-w" option. 121 122 - "git send-email" can be told not to thread the messages when 123 sending out more than one patches. 124 125 - "git config" learned NUL terminated output format via -z to 126 help scripts. 127 128 - "git add" learned "--refresh <paths>..." option to selectively refresh 129 the cached stat information. 130 131 - "git init -q" makes the command quieter. 132 133 - "git -p command" now has a cousin of opposite sex, "git --no-pager 134 command". 135 136* Updated behavior of existing commands. 137 138 - "gitweb" can offer multiple snapshot formats. 139 140 ***NOTE*** Unfortunately, this changes the format of the 141 $feature{snapshot}{default} entry in the per-site 142 configuration file 'gitweb_config.perl'. It used to be a 143 three-element tuple that describe a single format; with the 144 new configuration item format, you only have to say the name 145 of the format ('tgz', 'tbz2' or 'zip'). Please update the 146 your configuration file accordingly. 147 148 - "git clone" uses -l (hardlink files under .git) by default when 149 cloning locally. 150 151 - "git bundle create" can now create a bundle without negative refs, 152 i.e. "everything since the beginning up to certain points". 153 154 - "git diff" (but not the plumbing level "git diff-tree") now 155 recursively descends into trees by default. 156 157 - "git diff" does not show differences that come only from 158 stat-dirtiness in the form of "diff --git" header anymore. When 159 generating a textual diff, it shows a warning message at the end. 160 161 - The editor to use with many interactive commands can be 162 overridden with GIT_EDITOR environment variable, or if it 163 does not exist, with core.editor configuration variable. As 164 before, if you have neither, environment variables VISUAL 165 and EDITOR are consulted in this order, and then finally we 166 fall back on "vi". 167 168 - "git rm --cached" does not complain when removing a newly 169 added file from the index anymore. 170 171 - Options to "git log" to affect how --grep/--author options look for 172 given strings now have shorter abbreviations. -i is for ignore case, 173 and -E is for extended regexp. 174 175 - "git log" learned --log-size to show the number of bytes in 176 the log message part of the output to help qgit. 177 178 - "git svn dcommit" retains local merge information. 179 180 - "git svnimport" allows an empty string to be specified as the 181 trunk/ directory. This is necessary to suck data from a SVN 182 repository that doe not have trunk/ branches/ and tags/ organization 183 at all. 184 185 - "git config" to set values also honors type flags like --bool 186 and --int. 187 188 - core.quotepath configuration can be used to make textual git 189 output to emit most of the characters in the path literally. 190 191 - "git mergetool" chooses its backend more wisely, taking 192 notice of its environment such as use of X, Gnome/KDE, etc. 193 194 - "gitweb" shows merge commits a lot nicer than before. The 195 default view uses more compact --cc format, while the UI 196 allows to choose normal diff with any parent. 197 198 - snapshot files "gitweb" creates from a repository at 199 $path/$project/.git are more useful. We use $project part 200 in the filename, which we used to discard. 201 202 - "git cvsimport" creates lightweight tags; there is no 203 interesting information we can record in an annotated tag, 204 and the handcrafted ones the old code created was not 205 properly formed anyway. 206 207 - "git push" pretends that you immediately fetched back from 208 the remote by updating corresponding remote tracking 209 branches if you have any. 210 211 - The diffstat given after a merge (or a pull) honors the 212 color.diff configuration. 213 214 - "git commit --amend" is now compatible with various message source 215 options such as -m/-C/-c/-F. 216 217 - "git apply --whitespace=strip" removes blank lines added at 218 the end of the file. 219 220 - "git fetch" over git native protocols with "-v" option shows 221 connection status, and the IP address of the other end, to 222 help diagnosing problems. 223 224 - We used to have core.legacyheaders configuration, when 225 set to false, allowed git to write loose objects in a format 226 that mimicks the format used by objects stored in packs. It 227 turns out that this was not so useful. Although we will 228 continue to read objects written in that format, we do not 229 honor that configuration anymore and create loose objects in 230 the legacy/traditional format. 231 232 - "--find-copies-harder" option to diff family can now be 233 spelled as "-C -C" for brevity. 234 235 - "git mailsplit" (hence "git am") can read from Maildir 236 formatted mailboxes. 237 238 - "git cvsserver" does not barf upon seeing "cvs login" 239 request. 240 241 - "pack-objects" honors "delta" attribute set in 242 .gitattributes. It does not attempt to deltify blobs that 243 come from paths with delta attribute set to false. 244 245 - "new-workdir" script (in contrib) can now be used with a 246 bare repository. 247 248 - "git mergetool" learned to use gvimdiff. 249 250 - "gitview" (in contrib) has a better blame interface. 251 252 - "git log" and friends did not handle a commit log message 253 that is larger than 16kB; they do now. 254 255 - "--pretty=oneline" output format for "git log" and friends 256 deals with "malformed" commit log messages that have more 257 than one lines in the first paragraph better. We used to 258 show the first line, cutting the title at mid-sentence; we 259 concatenate them into a single line and treat the result as 260 "oneline". 261 262 - "git p4import" has been demoted to contrib status. For 263 a superior option, checkout the "git p4" front end to 264 "git fast-import" (also in contrib). The man page and p4 265 rpm have been removed as well. 266 267 - "git mailinfo" (hence "am") now tries to see if the message 268 is in utf-8 first, instead of assuming iso-8859-1, if 269 incoming e-mail does not say what encoding it is in. 270 271* Builds 272 273 - old-style function definitions (most notably, a function 274 without parameter defined with "func()", not "func(void)") 275 have been eradicated. 276 277 - "git tag" and "git verify-tag" have been rewritten in C. 278 279* Performance Tweaks 280 281 - "git pack-objects" avoids re-deltification cost by caching 282 small enough delta results it creates while looking for the 283 best delta candidates. 284 285 - "git pack-objects" learned a new heuristcs to prefer delta 286 that is shallower in depth over the smallest delta 287 possible. This improves both overall packfile access 288 performance and packfile density. 289 290 - diff-delta code that is used for packing has been improved 291 to work better on big files. 292 293 - when there are more than one pack files in the repository, 294 the runtime used to try finding an object always from the 295 newest packfile; it now tries the same packfile as we found 296 the object requested the last time, which exploits the 297 locality of references. 298 299 - verifying pack contents done by "git fsck --full" got boost 300 by carefully choosing the order to verify objects in them. 301 302 - "git read-tree -m" to read into an already populated index 303 has been optimized vastly. The effect of this can be seen 304 when switching branches that have differences in only a 305 handful paths. 306 307 - "git commit paths..." has also been optimized. 308 309 310Fixes since v1.5.2 311------------------ 312 313All of the fixes in v1.5.2 maintenance series are included in 314this release, unless otherwise noted. 315 316* Bugfixes 317 318 - "gitweb" had trouble handling non UTF-8 text with older 319 Encode.pm Perl module. 320 321 - "git-write-tree" had a bad interaction with racy-git avoidance and 322 gitattributes mechanisms. 323 324-- 325exec >/var/tmp/1 326O=v1.5.3-rc6-47-ge92ea62 327echo O=`git describe refs/heads/master` 328git shortlog --no-merges $O..refs/heads/master ^refs/heads/maint
