1GIT v1.6.1 Release Notes 2======================== 3 4Updates since v1.6.0 5-------------------- 6 7When some commands (e.g. "git log", "git diff") spawn pager internally, we 8used to make the pager the parent process of the git command that produces 9output. This meant that the exit status of the whole thing comes from the 10pager, not the underlying git command. We swapped the order of the 11processes around and you will see the exit code from the command from now 12on. 13 14(subsystems) 15 16* gitk can call out to git-gui to view "git blame" output; git-gui in turn 17 can run gitk from its blame view. 18 19* Various git-gui updates including updated translations. 20 21* Various gitweb updates from repo.or.cz installation. 22 23* Updates to emacs bindings. 24 25(portability) 26 27* A few test scripts used nonportable "grep" that did not work well on 28 some platforms, e.g. Solaris. 29 30* Sample pre-auto-gc script has OS X support. 31 32* Makefile has support for (ancient) FreeBSD 4.9. 33 34(performance) 35 36* Many operations that are lstat(3) heavy can be told to pre-execute 37 necessary lstat(3) in parallel before their main operations, which 38 potentially gives much improved performance for cold-cache cases or in 39 environments with weak metadata caching (e.g. NFS). 40 41* The underlying diff machinery to produce textual output has been 42 optimized, which would result in faster "git blame" processing. 43 44* Most of the test scripts (but not the ones that try to run servers) 45 can be run in parallel. 46 47* Bash completion of refnames in a repository with massive number of 48 refs has been optimized. 49 50* Cygwin port uses native stat/lstat implementations when applicable, 51 which leads to improved performance. 52 53* "git push" pays attention to alternate repositories to avoid sending 54 unnecessary objects. 55 56* "git svn" can rebuild an out-of-date rev_map file. 57 58(usability, bells and whistles) 59 60* When you mistype a command name, git helpfully suggests what it guesses 61 you might have meant to say. help.autocorrect configuration can be set 62 to a non-zero value to accept the suggestion when git can uniquely 63 guess. 64 65* The packfile machinery hopefully is more robust when dealing with 66 corrupt packs if redundant objects involved in the corruption are 67 available elsewhere. 68 69* "git add -N path..." adds the named paths as an empty blob, so that 70 subsequent "git diff" will show a diff as if they are creation events. 71 72* "git add" gained a built-in synonym for people who want to say "stage 73 changes" instead of "add contents to the staging area" which amounts 74 to the same thing. 75 76* "git apply" learned --include=paths option, similar to the existing 77 --exclude=paths option. 78 79* "git bisect" is careful about a user mistake and suggests testing of 80 merge base first when good is not a strict ancestor of bad. 81 82* "git bisect skip" can take a range of commits. 83 84* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding 85 by default. 86 87* "git check-attr --stdin" can check attributes for multiple paths. 88 89* "git checkout --track origin/hack" used to be a syntax error. It now 90 DWIMs to create a corresponding local branch "hack", i.e. acts as if you 91 said "git checkout --track -b hack origin/hack". 92 93* "git checkout --ours/--theirs" can be used to check out one side of a 94 conflicting merge during conflict resolution. 95 96* "git checkout -m" can be used to recreate the initial conflicted state 97 during conflict resolution. 98 99* "git cherry-pick" can also utilize rerere for conflict resolution. 100 101* "git clone" learned to be verbose with -v 102 103* "git commit --author=$name" can look up author name from existing 104 commits. 105 106* output from "git commit" has been reworded in a more concise and yet 107 more informative way. 108 109* "git count-objects" reports the on-disk footprint for packfiles and 110 their corresponding idx files. 111 112* "git daemon" learned --max-connections=<count> option. 113 114* "git daemon" exports REMOTE_ADDR to record client address, so that 115 spawned programs can act differently on it. 116 117* "git describe --tags" favours closer lightweight tags than farther 118 annotated tags now. 119 120* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a 121 configuration option. 122 123* "git diff" learned to put more sensible hunk headers for Python, 124 HTML and ObjC contents. 125 126* "git diff" learned to vary the a/ vs b/ prefix depending on what are 127 being compared, controlled by diff.mnemonicprefix configuration. 128 129* "git diff" learned --dirstat-by-file to count changed files, not number 130 of lines, when summarizing the global picture. 131 132* "git diff" learned "textconv" filters --- a binary or hard-to-read 133 contents can be munged into human readable form and the difference 134 between the results of the conversion can be viewed (obviously this 135 cannot produce a patch that can be applied, so this is disabled in 136 format-patch among other things). 137 138* "--cached" option to "git diff has an easier to remember synonym "--staged", 139 to ask "what is the difference between the given commit and the 140 contents staged in the index?" 141 142* "git for-each-ref" learned "refname:short" token that gives an 143 unambiguously abbreviated refname. 144 145* Auto-numbering of the subject lines is the default for "git 146 format-patch" now. 147 148* "git grep" learned to accept -z similar to GNU grep. 149 150* "git help" learned to use GIT_MAN_VIEWER environment variable before 151 using "man" program. 152 153* "git imap-send" can optionally talk SSL. 154 155* "git index-pack" is more careful against disk corruption while 156 completing a thin pack. 157 158* "git log --check" and "git log --exit-code" passes their underlying diff 159 status with their exit status code. 160 161* "git log" learned --simplify-merges, a milder variant of --full-history; 162 "gitk --simplify-merges" is easier to view than with --full-history. 163 164* "git log" learned "--source" to show what ref each commit was reached 165 from. 166 167* "git log" also learned "--simplify-by-decoration" to show the 168 birds-eye-view of the topology of the history. 169 170* "git log --pretty=format:" learned "%d" format element that inserts 171 names of tags that point at the commit. 172 173* "git merge --squash" and "git merge --no-ff" into an unborn branch are 174 noticed as user errors. 175 176* "git merge -s $strategy" can use a custom built strategy if you have a 177 command "git-merge-$strategy" on your $PATH. 178 179* "git pull" (and "git fetch") can be told to operate "-v"erbosely or 180 "-q"uietly. 181 182* "git push" can be told to reject deletion of refs with receive.denyDeletes 183 configuration. 184 185* "git rebase" honours pre-rebase hook; use --no-verify to bypass it. 186 187* "git rebase -p" uses interactive rebase machinery now to preserve the merges. 188 189* "git reflog expire branch" can be used in place of "git reflog expire 190 refs/heads/branch". 191 192* "git remote show $remote" lists remote branches one-per-line now. 193 194* "git send-email" can be given revision range instead of files and 195 maildirs on the command line, and automatically runs format-patch to 196 generate patches for the given revision range. 197 198* "git submodule foreach" subcommand allows you to iterate over checked 199 out submodules. 200 201* "git submodule sync" subcommands allows you to update the origin URL 202 recorded in submodule directories from the toplevel .gitmodules file. 203 204* "git svn branch" can create new branches on the other end. 205 206* "gitweb" can use more saner PATH_INFO based URL. 207 208(internal) 209 210* "git hash-object" learned to lie about the path being hashed, so that 211 correct gitattributes processing can be done while hashing contents 212 stored in a temporary file. 213 214* various callers of git-merge-recursive avoid forking it as an external 215 process. 216 217* Git class defined in "Git.pm" can be subclasses a bit more easily. 218 219* We used to link GNU regex library as a compatibility layer for some 220 platforms, but it turns out it is not necessary on most of them. 221 222* Some path handling routines used fixed number of buffers used alternately 223 but depending on the call depth, this arrangement led to hard to track 224 bugs. This issue is being addressed. 225 226 227Fixes since v1.6.0 228------------------ 229 230All of the fixes in v1.6.0.X maintenance series are included in this 231release, unless otherwise noted. 232 233* Porcelains implemented as shell scripts were utterly confused when you 234 entered to a subdirectory of a work tree from sideways, following a 235 symbolic link (this may need to be backported to older releases later). 236 237* Tracking symbolic links would work better on filesystems whose lstat() 238 returns incorrect st_size value for them. 239 240* "git add" and "git update-index" incorrectly allowed adding S/F when S 241 is a tracked symlink that points at a directory D that has a path F in 242 it (we still need to fix a similar nonsense when S is a submodule and F 243 is a path in it). 244 245* "git am" after stopping at a broken patch lost --whitespace, -C, -p and 246 --3way options given from the command line initially. 247 248* "git diff --stdin" used to take two trees on a line and compared them, 249 but we dropped support for such a use case long time ago. This has 250 been resurrected. 251 252* "git filter-branch" failed to rewrite a tag name with slashes in it. 253 254* "git http-push" did not understand URI scheme other than opaquelocktoken 255 when acquiring a lock from the server (this may need to be backported to 256 older releases later). 257 258* After "git rebase -p" stopped with conflicts while replaying a merge, 259 "git rebase --continue" did not work (may need to be backported to older 260 releases). 261 262* "git revert" records relative to which parent a revert was made when 263 reverting a merge. Together with new documentation that explains issues 264 around reverting a merge and merging from the updated branch later, this 265 hopefully will reduce user confusion (this may need to be backported to 266 older releases later). 267 268* "git rm --cached" used to allow an empty blob that was added earlier to 269 be removed without --force, even when the file in the work tree has 270 since been modified. 271 272* "git push --tags --all $there" failed with generic usage message without 273 telling saying these two options are incompatible. 274 275* "git log --author/--committer" match used to potentially match the 276 timestamp part, exposing internal implementation detail. Also these did 277 not work with --fixed-strings match at all. 278 279* "gitweb" did not mark non-ASCII characters imported from external HTML fragments 280 correctly.
