   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(portability)
  24
  25* A few test scripts used nonportable "grep" that did not work well on
  26  some platforms, e.g. Solaris.
  27
  28* Sample pre-auto-gc script has OS X support.
  29
  30* Makefile has support for (ancient) FreeBSD 4.9.
  31
  32(performance)
  33
  34* The underlying diff machinery to produce textual output has been
  35  optimized, which would result in faster "git blame" processing.
  36
  37* Most of the test scripts (but not the ones that try to run servers)
  38  can be run in parallel.
  39
  40* Bash completion of refnames in a repository with massive number of
  41  refs has been optimized.
  42
  43* Cygwin port uses native stat/lstat implementations when applicable,
  44  which leads to improved performance.
  45
  46* "git push" pays attention to alternate repositories to avoid sending
  47  unnecessary objects.
  48
  49* "git svn" can rebuild an out-of-date rev_map file.
  50
  51(usability, bells and whistles)
  52
  53* When you mistype a command name, git helpfully suggests what it guesses
  54  you might have meant to say.  help.autocorrect configuration can be set
  55  to a non-zero value to accept the suggestion when git can uniquely
  56  guess.
  57
  58* The packfile machinery hopefully is more robust when dealilng with
  59  corrupt packs if redundant objects involved in the corruption are
  60  available elsehwere.
  61
  62* "git add -N path..." adds the named paths as an empty blob, so that
  63  subsequent "git diff" will show a diff as if they are creation events.
  64
  65* "git apply" learned --include=paths option, similar to the existing
  66  --exclude=paths option.
  67
  68* "git bisect" is careful about a user mistake and suggests testing of
  69  merge base first when good is not a strict ancestor of bad.
  70
  71* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
  72  by default.
  73
  74* "git check-attr --stdin" can check attributes for multiple paths.
  75
  76* "git checkout --track origin/hack" used to be a syntax error.  It now
  77  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
  78  said "git checkout --track -b hack origin/hack".
  79
  80* "git checkout --ours/--theirs" can be used to check out one side of a
  81  conflicting merge during conflict resolution.
  82
  83* "git checkout -m" can be used to recreate the initial conflicted state
  84  during conflict resolution.
  85
  86* "git cherry-pick" can also utilize rerere for conflict resolution.
  87
  88* "git clone" learned to be verbose with -v
  89
  90* "git commit --author=$name" can look up author name from existing
  91  commits.
  92
  93* output from "git commit" has been reworded in a more concise and yet
  94  more informative way.
  95
  96* "git count-objects" reports the on-disk footprint for packfiles and
  97  their corresponding idx files.
  98
  99* "git daemon" learned --max-connections=<count> option.
 100
 101* "git daemon" exports REMOTE_ADDR to record client address, so that
 102  spawned programs can act differently on it.
 103
 104* "git describe --tags" favours closer lightweight tags than farther
 105  annotated tags now.
 106
 107* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
 108  configuration option.
 109
 110* "git diff" learned to put more sensible hunk headers for Python,
 111  HTML and ObjC contents.
 112
 113* "git diff" learned to vary the a/ vs b/ prefix depending on what are
 114  being compared, controlled by diff.mnemonicprefix configuration.
 115
 116* "git diff" learned --dirstat-by-file to count changed files, not number
 117  of lines, when summarizing the global picture.
 118
 119* "git diff" learned "textconv" filters --- a binary or hard-to-read
 120  contents can be munged into human readable form and the difference
 121  between the results of the conversion can be viewed (obviously this
 122  cannot produce a patch that can be applied, so this is disabled in
 123  format-patch among other things).
 124
 125* "git diff" hunk header pattern for ObjC has been added.
 126
 127* "--cached" option to "git diff has an easier to remember synonym "--staged",
 128  to ask "what is the difference between the given commit and the
 129  contents staged in the index?"
 130
 131* a "textconv" filter that makes binary files textual form for human
 132   consumption can be specified as an attribute for paths; "git diff"
 133   learnt to make use of it.
 134
 135* "git for-each-ref" learned "refname:short" token that gives an
 136  unambiguously abbreviated refname.
 137
 138* Auto-numbering of the subject lines is the default for "git
 139  format-patch" now.
 140
 141* "git grep" learned to accept -z similar to GNU grep.
 142
 143* "git help" learned to use GIT_MAN_VIEWER environment variable before
 144  using "man" program.
 145
 146* "git imap-send" can optionally talk SSL.
 147
 148* "git index-pack" is more careful against disk corruption while
 149  completing a thin pack.
 150
 151* "git log --check" and "git log --exit-code" passes their underlying diff
 152  status with their exit status code.
 153
 154* "git log" learned --simplify-merges, a milder variant of --full-history;
 155  "gitk --simplify-merges" is easier to view than with --full-history.
 156
 157* "git log" learned "--source" to show what ref each commit was reached
 158  from.
 159
 160* "git log" also learned "--simplify-by-decration" to show the
 161  birds-eye-view of the topology of the history.
 162
 163* "git log --pretty=format:" learned "%d" format element that inserts
 164  names of tags that point at the commit.
 165
 166* "git merge --squash" and "git merge --no-ff" into an unborn branch are
 167  noticed as user errors.
 168
 169* "git merge -s $strategy" can use a custom built strategy if you have a
 170  command "git-merge-$strategy" on your $PATH.
 171
 172* "git push" can be told to reject deletion of refs with receive.denyDeletes
 173  configuration.
 174
 175* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
 176
 177* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
 178
 179* "git reflog expire branch" can be used in place of "git reflog expire
 180  refs/heads/branch".
 181
 182* "git remote show $remote" lists remote branches one-per-line now.
 183
 184* when giving up resolving a conflicted merge, "git reset --hard" failed
 185  to remove new paths from the working tree. [cherry-pick to 'maint'?]
 186
 187* "git submodule foreach" subcommand allows you to iterate over checked
 188  out submodules.
 189
 190* "git submodule sync" subcommands allows you to update the origin URL
 191  recorded in submodule directories from the toplevel .gitmodules file.
 192
 193* "git svn branch" can create new branches on the other end.
 194
 195* "gitweb" can use more saner PATH_INFO based URL.
 196
 197(internal)
 198
 199* "git hash-object" learned to lie about the path being hashed, so that
 200  correct gitattributes processing can be done while hashing contents
 201  stored in a temporary file.
 202
 203* various callers of git-merge-recursive avoid forking it as an external
 204  process.
 205
 206* Git class defined in "Git.pm" can be subclasses a bit more easily.
 207
 208* We used to link GNU regex library as a compatibility layer for some
 209  platforms, but it turns out it is not necessary on most of them.
 210
 211* Some path handling routines used fixed number of buffers used alternately
 212  but depending on the call depth, this arrangement led to hard to track
 213  bugs.  This issue is being addressed.
 214
 215
 216Fixes since v1.6.0
 217------------------
 218
 219All of the fixes in v1.6.0.X maintenance series are included in this
 220release, unless otherwise noted.
 221
 222* "git add" and "git update-index" incorrectly allowed adding S/F when S
 223  is a tracked symlink that points at a directory D that has a path F in
 224  it (we still need to fix a similar nonsense when S is a submodule and F
 225  is a path in it).
 226
 227* "git diff --stdin" used to take two trees on a line and compared them,
 228  but we dropped support for such a use case long time ago.  This has
 229  been resurrected.
 230
 231* Giving 3 or more tree-ish to "git diff" is supposed to show the combined
 232  diff from second and subsequent trees to the first one.  b75271d ("git
 233  diff <tree>{3,}": do not reverse order of arguments, 2008-10-10) needs
 234  to be cherry-picked to 'maint'.
 235
 236* "git filter-branch" failed to rewrite a tag name with slashes in it.
 237
 238* "git repack" used to grab objects out of packs marked with .keep
 239  into a new pack (fix scheduled to be further downmerged to maint).
 240
 241* "git push --tags --all $there" failed with generic usage message without
 242  telling saying these two options are incompatible.
 243
 244* "git log --author/--committer" match used to potentially match the
 245  timestamp part, exposing internal implementation detail.  Also these did
 246  not work with --fixed-strings match at all.
 247
 248* "git tag" did not complain about incompatible combination of options
 249  e.g. "tag -l -d" (fix scheduled to be further downmerged to maint).
 250
 251* Internal diff machinery had a corner case performance bug that choked on a
 252  large file with many repeated contents (fix scheduled to be further cherry-
 253  picked to maint).
