Documentation / RelNotes-1.5.4.txton commit pack-objects: remove redundant and wrong call to deflateEnd() (8c3c7b2)
   1GIT v1.5.4 Release Notes
   2========================
   3
   4Removal
   5-------
   6
   7 * "git svnimport" was removed in favor of "git svn".  It is still there
   8   in the source tree (contrib/examples) but unsupported.
   9
  10 * As git-commit and git-status have been rewritten, "git runstatus"
  11   helper script lost all its users and has been removed.
  12
  13
  14Deprecation notices
  15-------------------
  16
  17 * The next feature release of git (this change is scheduled for v1.6.0)
  18   will by default install dashed form of commands (e.g. "git-commit")
  19   outside of users' normal $PATH, and will install only selected
  20   commands ("git" itself, and "gitk") in $PATH.  This implies:
  21
  22   - Using dashed forms of git commands (e.g. "git-commit") from the
  23     command line has been informally deprecated since early 2006, but
  24     now it officially is, and will be removed in the future.  Use
  25     dashless forms (e.g. "git commit") instead.
  26
  27   - Using dashed forms from your scripts, without first prepending the
  28     return value from "git --exec-path" to the scripts' PATH, has been
  29     informally deprecated since early 2006, but now it officially is.
  30
  31   - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
  32     PATH" early in your script is not deprecated with this change.
  33
  34  Users are strongly encouraged to adjust their habits and scripts now
  35  to prepare for this.
  36
  37 * The post-receive hook was introduced in March 2007 to supersede
  38   the post-update hook, primarily to overcome the command line length
  39   limitation of the latter.  Use of post-update hook will be deprecated
  40   in future versions of git, starting from v1.6.0.
  41
  42 * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
  43   option, and will be removed in the future.
  44
  45 * "git peek-remote" is deprecated, as "git ls-remote" was written in C
  46   and works for all transports; "git peek-remote" will be removed in
  47   the future.
  48
  49 * From v1.6.0, the repack.usedeltabaseoffset config option will default
  50   to true, which will give denser packfiles (i.e. more efficient storage).
  51   The downside is that git older than version 1.4.4 will not be able
  52   to directly use a repository packed using this setting.
  53
  54 * From v1.6.0, the pack.indexversion config option will default to 2,
  55   which is slightly more efficient, and makes repacking more immune to
  56   data corruptions.  Git older than version 1.5.2 may revert to version 1
  57   of the pack index with a manual "git index-pack" to be able to directly
  58   access corresponding pack files.
  59
  60
  61Updates since v1.5.3
  62--------------------
  63
  64 * Comes with much improved gitk.
  65
  66 * Comes with "git gui" 0.9.1 with i18n.
  67
  68 * gitk is now merged as a subdirectory of git.git project, in
  69   preparation for its i18n.
  70
  71 * progress displays from many commands are a lot nicer to the eye.
  72   Transfer commands show throughput data.
  73
  74 * many commands that pay attention to per-directory .gitignore now do
  75   so lazily, which makes the usual case go much faster.
  76
  77 * Output processing for '--pretty=format:<user format>' has been
  78   optimized.
  79
  80 * Rename detection of diff family while detecting exact matches has
  81   been greatly optimized.
  82
  83 * Rename detection of diff family tries to make more natural looking
  84   pairing.  Earlier, if multiple identical rename sources were
  85   found in the preimage, the source used was picked pretty much at random.
  86
  87 * Value "true" for color.diff and color.status configuration used to
  88   mean "always" (even when the output is not going to a terminal).
  89   This has been corrected to mean the same thing as "auto".
  90
  91 * "git diff" Porcelain now respects diff.external configuration, which
  92   is another way to specify GIT_EXTERNAL_DIFF.
  93
  94 * "git diff" can be told to use different prefixes other than
  95   "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".
  96
  97 * "git diff" sometimes did not quote paths with funny
  98   characters properly.
  99
 100 * "git log" (and any revision traversal commands) misbehaved
 101   when --diff-filter is given but was not asked to actually
 102   produce diff.
 103
 104 * HTTP proxy can be specified per remote repository using
 105   remote.*.httpproxy configuration, or global http.proxy configuration
 106   variable.
 107
 108 * Various Perforce importer updates.
 109
 110 * Example update and post-receive hooks have been improved.
 111
 112 * Any command that wants to take a commit object name can now use
 113   ":/string" syntax to name a commit.
 114
 115 * "git reset" is now built-in and its output can be squelched with -q.
 116
 117 * "git reset --hard" does not make any sense in a bare
 118   repository, but did not error out; fixed.
 119
 120 * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
 121
 122 * "git rebase" learned --whitespace option.
 123
 124 * In "git rebase", when you decide not to replay a particular change
 125   after the command stopped with a conflict, you can say "git rebase
 126   --skip" without first running "git reset --hard", as the command now
 127   runs it for you.
 128
 129 * "git rebase --interactive" mode can now work on detached HEAD.
 130
 131 * Other minor to serious bugs in "git rebase -i" have been fixed.
 132
 133 * "git rebase" now detaches head during its operation, so after a
 134   successful "git rebase" operation, the reflog entry branch@{1} for
 135   the current branch points at the commit before the rebase was
 136   started.
 137
 138 * "git rebase -i" also triggers rerere to help your repeated merges.
 139
 140 * "git merge" can call the "post-merge" hook.
 141
 142 * "git pack-objects" can optionally run deltification with multiple
 143   threads.
 144
 145 * "git archive" can optionally substitute keywords in files marked with
 146   export-subst attribute.
 147
 148 * "git cherry-pick" made a misguided attempt to repeat the original
 149   command line in the generated log message, when told to cherry-pick a
 150   commit by naming a tag that points at it.  It does not anymore.
 151
 152 * "git for-each-ref" learned %(xxxdate:<dateformat>) syntax to show the
 153   various date fields in different formats.
 154
 155 * "git gc --auto" is a low-impact way to automatically run a variant of
 156   "git repack" that does not lose unreferenced objects (read: safer
 157   than the usual one) after the user accumulates too many loose
 158   objects.
 159
 160 * "git clean" has been rewritten in C.
 161
 162 * You need to explicitly set clean.requireForce to "false" to allow
 163   "git clean" without -f to do any damage (lack of the configuration
 164   variable used to mean "do not require -f option to lose untracked
 165   files", but we now use the safer default).
 166
 167 * The kinds of whitespace errors "git diff" and "git apply" notice (and
 168   fix) can be controlled via 'core.whitespace' configuration variable
 169   and 'whitespace' attribute in .gitattributes file.
 170
 171 * "git push" learned --dry-run option to show what would happen if a
 172   push is run.
 173
 174 * "git push" does not update a tracking ref on the local side when the
 175   remote refused to update the corresponding ref.
 176
 177 * "git push" learned --mirror option.  This is to push the local refs
 178   one-to-one to the remote, and deletes refs from the remote that do
 179   not exist anymore in the repository on the pushing side.
 180
 181 * "git push" can remove a corrupt ref at the remote site with the usual
 182   ":ref" refspec.
 183
 184 * "git remote" knows --mirror mode.  This is to set up configuration to
 185   push into a remote repository to store local branch heads to the same
 186   branch on the remote side, and remove branch heads locally removed
 187   from local repository at the same time.  Suitable for pushing into a
 188   back-up repository.
 189
 190 * "git remote" learned "rm" subcommand.
 191
 192 * "git cvsserver" can be run via "git shell".  Also, "cvs" is
 193   recognized as a synonym for "git cvsserver", so that CVS users
 194   can be switched to git just by changing their login shell.
 195
 196 * "git cvsserver" acts more like receive-pack by running post-receive
 197   and post-update hooks.
 198
 199 * "git am" and "git rebase" are far less verbose.
 200
 201 * "git pull" learned to pass --[no-]ff option to underlying "git
 202   merge".
 203
 204 * "git pull --rebase" is a different way to integrate what you fetched
 205   into your current branch.
 206
 207 * "git fast-export" produces datastream that can be fed to fast-import
 208   to reproduce the history recorded in a git repository.
 209
 210 * "git add -i" takes pathspecs to limit the set of files to work on.
 211
 212 * "git add -p" is a short-hand to go directly to the selective patch
 213   subcommand in the interactive command loop and to exit when done.
 214
 215 * "git add -i" UI has been colorized.  The interactive prompt
 216   and menu can be colored by setting color.interactive
 217   configuration.  The diff output (including the hunk picker)
 218   are colored with color.diff configuration.
 219
 220 * "git commit --allow-empty" allows you to create a single-parent
 221   commit that records the same tree as its parent, overriding the usual
 222   safety valve.
 223
 224 * "git commit --amend" can amend a merge that does not change the tree
 225   from its first parent.
 226
 227 * "git commit" used to unconditionally strip comment lines that
 228   began with '#' and removed excess blank lines.  This
 229   behaviour has been made configurable.
 230
 231 * "git commit" has been rewritten in C.
 232
 233 * "git stash random-text" does not create a new stash anymore.  It was
 234   a UI mistake.  Use "git stash save random-text", or "git stash"
 235   (without extra args) for that.
 236
 237 * "git stash clear extra-text" does not clear the whole stash
 238   anymore.  It is tempting to expect "git stash clear stash@{2}"
 239   to drop only a single named stash entry, and it is rude to
 240   discard everything when that is asked (but not provided).
 241
 242 * "git prune --expire <time>" can exempt young loose objects from
 243   getting pruned.
 244
 245 * "git branch --contains <commit>" can list branches that are
 246   descendants of a given commit.
 247
 248 * "git log" learned --early-output option to help interactive GUI
 249   implementations.
 250
 251 * "git bisect" learned "skip" action to mark untestable commits.
 252
 253 * "git bisect visualize" learned a shorter synonym "git bisect view".
 254
 255 * "git bisect visualize" runs "git log" in a non-windowed
 256   environments.  It also can be told what command to run (e.g. "git
 257   bisect visualize tig").
 258
 259 * "git format-patch" learned "format.numbered" configuration variable
 260   to automatically turn --numbered option on when more than one commits
 261   are formatted.
 262
 263 * "git ls-files" learned "--exclude-standard" to use the canned set of
 264   exclude files.
 265
 266 * "git tag -a -f existing" begins the editor session using the existing
 267   annotation message.
 268
 269 * "git tag -m one -m bar" (multiple -m options) behaves similarly to
 270   "git commit"; the parameters to -m options are formatted as separate
 271   paragraphs.
 272
 273 * The format "git show" outputs an annotated tag has been updated to
 274   include "Tagger: " and "Date: " lines from the tag itself.  Strictly
 275   speaking this is a backward incompatible change, but this is a
 276   reasonable usability fix and people's scripts shouldn't have been
 277   relying on the exact output from "git show" Porcelain anyway.
 278
 279 * "git cvsimport" did not notice errors from underlying "cvsps"
 280   and produced a corrupt import silently.
 281
 282 * "git cvsexportcommit" learned -w option to specify and switch to the
 283   CVS working directory.
 284
 285 * "git checkout" from a subdirectory learned to use "../path" to allow
 286   checking out a path outside the current directory without cd'ing up.
 287
 288 * "git checkout" from and to detached HEAD leaves a bit more
 289   information in the reflog.
 290
 291 * "git send-email --dry-run" shows full headers for easier diagnosis.
 292
 293 * "git merge-ours" is now built-in.
 294
 295 * "git svn" learned "info" and "show-externals" subcommands.
 296
 297 * "git svn" run from a subdirectory failed to read settings from the
 298   .git/config.
 299
 300 * "git svn" learned --use-log-author option, which picks up more
 301   descriptive name from From: and Signed-off-by: lines in the commit
 302   message.
 303
 304 * "git svn" wasted way too much disk to record revision mappings
 305   between svn and git; a new representation that is much more compact
 306   for this information has been introduced to correct this.
 307
 308 * "git svn" left temporary index files it used without cleaning them
 309   up; this was corrected.
 310
 311 * "git status" from a subdirectory now shows relative paths, which
 312   makes copy-and-pasting for git-checkout/git-add/git-rm easier.  The
 313   traditional behaviour to show the full path relative to the top of
 314   the work tree can be had by setting status.relativepaths
 315   configuration variable to false.
 316
 317 * "git blame" kept text for each annotated revision in core needlessly;
 318   this has been corrected.
 319
 320 * "git shortlog" learned to default to HEAD when the standard input is
 321   a terminal and the user did not give any revision parameter.
 322
 323 * "git shortlog" learned "-e" option to show e-mail addresses as well as
 324   authors' names.
 325
 326 * "git help" learned "-w" option to show documentation in browsers.
 327
 328 * In addition there are quite a few internal clean-ups. Notably
 329
 330   - many fork/exec have been replaced with run-command API,
 331     brought from the msysgit effort.
 332
 333   - introduction and more use of the option parser API.
 334
 335   - enhancement and more use of the strbuf API.
 336
 337
 338Fixes since v1.5.3
 339------------------
 340
 341All of the fixes in v1.5.3 maintenance series are included in
 342this release, unless otherwise noted.
 343
 344These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
 345series.
 346
 347 * The way "git diff --check" behaves is much more consistent with the way
 348   "git apply --whitespace=warn" works.
 349
 350 * "git svn" talking with the SVN over http will correctly quote branch
 351   and project names.
 352
 353 * "git config" did not work correctly on platforms that define
 354   REG_NOMATCH to an even number.
 355
 356 * Recent versions of AsciiDoc 8 has a change to break our
 357   documentation; a workaround has been implemented.
