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 0.8.0. 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* Updated behavior of existing commands. 134 135 - "gitweb" can offer multiple snapshot formats. 136 137 ***NOTE*** Unfortunately, this changes the format of the 138 $feature{snapshot}{default} entry in the per-site 139 configuration file 'gitweb_config.perl'. It used to be a 140 three-element tuple that describe a single format; with the 141 new configuration item format, you only have to say the name 142 of the format ('tgz', 'tbz2' or 'zip'). Please update the 143 your configuration file accordingly. 144 145 - "git clone" uses -l (hardlink files under .git) by default when 146 cloning locally. 147 148 - "git bundle create" can now create a bundle without negative refs, 149 i.e. "everything since the beginning up to certain points". 150 151 - "git diff" (but not the plumbing level "git diff-tree") now 152 recursively descends into trees by default. 153 154 - "git diff" does not show differences that come only from 155 stat-dirtiness in the form of "diff --git" header anymore. When 156 generating a textual diff, it shows a warning message at the end. 157 158 - The editor to use with many interactive commands can be 159 overridden with GIT_EDITOR environment variable, or if it 160 does not exist, with core.editor configuration variable. As 161 before, if you have neither, environment variables VISUAL 162 and EDITOR are consulted in this order, and then finally we 163 fall back on "vi". 164 165 - "git rm --cached" does not complain when removing a newly 166 added file from the index anymore. 167 168 - Options to "git log" to affect how --grep/--author options look for 169 given strings now have shorter abbreviations. -i is for ignore case, 170 and -E is for extended regexp. 171 172 - "git log" learned --log-size to show the number of bytes in 173 the log message part of the output to help qgit. 174 175 - "git svn dcommit" retains local merge information. 176 177 - "git svnimport" allows an empty string to be specified as the 178 trunk/ directory. This is necessary to suck data from a SVN 179 repository that doe not have trunk/ branches/ and tags/ organization 180 at all. 181 182 - "git config" to set values also honors type flags like --bool 183 and --int. 184 185 - core.quotepath configuration can be used to make textual git 186 output to emit most of the characters in the path literally. 187 188 - "git mergetool" chooses its backend more wisely, taking 189 notice of its environment such as use of X, Gnome/KDE, etc. 190 191 - "gitweb" shows merge commits a lot nicer than before. The 192 default view uses more compact --cc format, while the UI 193 allows to choose normal diff with any parent. 194 195 - snapshot files "gitweb" creates from a repository at 196 $path/$project/.git are more useful. We use $project part 197 in the filename, which we used to discard. 198 199 - "git cvsimport" creates lightweight tags; there is no 200 interesting information we can record in an annotated tag, 201 and the handcrafted ones the old code created was not 202 properly formed anyway. 203 204 - "git push" pretends that you immediately fetched back from 205 the remote by updating corresponding remote tracking 206 branches if you have any. 207 208 - The diffstat given after a merge (or a pull) honors the 209 color.diff configuration. 210 211 - "git commit --amend" is now compatible with various message source 212 options such as -m/-C/-c/-F. 213 214 - "git apply --whitespace=strip" removes blank lines added at 215 the end of the file. 216 217 - "git fetch" over git native protocols with "-v" option shows 218 connection status, and the IP address of the other end, to 219 help diagnosing problems. 220 221 - We used to have core.legacyheaders configuration, when 222 set to false, allowed git to write loose objects in a format 223 that mimicks the format used by objects stored in packs. It 224 turns out that this was not so useful. Although we will 225 continue to read objects written in that format, we do not 226 honor that configuration anymore and create loose objects in 227 the legacy/traditional format. 228 229 - "--find-copies-harder" option to diff family can now be 230 spelled as "-C -C" for brevity. 231 232 - "git mailsplit" (hence "git am") can read from Maildir 233 formatted mailboxes. 234 235 - "git cvsserver" does not barf upon seeing "cvs login" 236 request. 237 238 - "pack-objects" honors "delta" attribute set in 239 .gitattributes. It does not attempt to deltify blobs that 240 come from paths with delta attribute set to false. 241 242 - "new-workdir" script (in contrib) can now be used with a 243 bare repository. 244 245 - "git mergetool" learned to use gvimdiff. 246 247 - "gitview" (in contrib) has a better blame interface. 248 249 - "git log" and friends did not handle a commit log message 250 that is larger than 16kB; they do now. 251 252 - "--pretty=oneline" output format for "git log" and friends 253 deals with "malformed" commit log messages that have more 254 than one lines in the first paragraph better. We used to 255 show the first line, cutting the title at mid-sentence; we 256 concatenate them into a single line and treat the result as 257 "oneline". 258 259 - "git p4import" has been demoted to contrib status. For 260 a superior option, checkout the "git p4" front end to 261 "git fast-import" (also in contrib). The man page and p4 262 rpm have been removed as well. 263 264 - "git mailinfo" (hence "am") now tries to see if the message 265 is in utf-8 first, instead of assuming iso-8859-1, if 266 incoming e-mail does not say what encoding it is in. 267 268* Builds 269 270 - old-style function definitions (most notably, a function 271 without parameter defined with "func()", not "func(void)") 272 have been eradicated. 273 274 - "git tag" and "git verify-tag" have been rewritten in C. 275 276* Performance Tweaks 277 278 - "git pack-objects" avoids re-deltification cost by caching 279 small enough delta results it creates while looking for the 280 best delta candidates. 281 282 - "git pack-objects" learned a new heuristcs to prefer delta 283 that is shallower in depth over the smallest delta 284 possible. This improves both overall packfile access 285 performance and packfile density. 286 287 - diff-delta code that is used for packing has been improved 288 to work better on big files. 289 290 - when there are more than one pack files in the repository, 291 the runtime used to try finding an object always from the 292 newest packfile; it now tries the same packfile as we found 293 the object requested the last time, which exploits the 294 locality of references. 295 296 - verifying pack contents done by "git fsck --full" got boost 297 by carefully choosing the order to verify objects in them. 298 299 - "git read-tree -m" to read into an already populated index 300 has been optimized vastly. The effect of this can be seen 301 when switching branches that have differences in only a 302 handful paths. 303 304 - "git commit paths..." has also been optimized. 305 306 307Fixes since v1.5.2 308------------------ 309 310All of the fixes in v1.5.2 maintenance series are included in 311this release, unless otherwise noted. 312 313* Bugfixes 314 315 - "gitweb" had trouble handling non UTF-8 text with older 316 Encode.pm Perl module. 317 318-- 319exec >/var/tmp/1 320O=v1.5.3-rc4 321echo O=`git describe refs/heads/master` 322git shortlog --no-merges $O..refs/heads/master ^refs/heads/maint
