  45DESCRIPTION
  46-----------
  47
  48Lists commit objects in reverse chronological order starting at the
  49given commit(s), taking ancestry relationship into account.  This is
  50useful to produce human-readable log output.
  51
  52Commits which are stated with a preceding '{caret}' cause listing to
  53stop at that point. Their parents are implied. Thus the following
  54command:
  55
  56-----------------------------------------------------------------------
  57        $ git-rev-list foo bar ^baz
  58-----------------------------------------------------------------------
  59
  60means "list all the commits which are included in 'foo' and 'bar', but
  61not in 'baz'".
  62
  63A special notation "'<commit1>'..'<commit2>'" can be used as a
  64short-hand for "{caret}'<commit1>' '<commit2>'". For example, either of
  65the following may be used interchangeably:
  66
  67-----------------------------------------------------------------------
  68        $ git-rev-list origin..HEAD
  69        $ git-rev-list HEAD ^origin
  70-----------------------------------------------------------------------
  71
  72Another special notation is "'<commit1>'...'<commit2>'" which is useful
  73for merges.  The resulting set of commits is the symmetric difference
  74between the two operands.  The following two commands are equivalent:
  75
  76-----------------------------------------------------------------------
  77        $ git-rev-list A B --not $(git-merge-base --all A B)
  78        $ git-rev-list A...B
  79-----------------------------------------------------------------------
  80
  81gitlink:git-rev-list[1] is a very essential git program, since it
  82provides the ability to build and traverse commit ancestry graphs. For
  83this reason, it has a lot of different options that enables it to be
  84used by commands as different as gitlink:git-bisect[1] and
  85gitlink:git-repack[1].
  86
  87OPTIONS
  88-------
  89
  90Commit Formatting
  91~~~~~~~~~~~~~~~~~
  92
  93Using these options, gitlink:git-rev-list[1] will act similar to the
  94more specialized family of commit log tools: gitlink:git-log[1],
  95gitlink:git-show[1], and gitlink:git-whatchanged[1]
  96
  97include::pretty-options.txt[]
  98
  99--relative-date::
 100
 101        Synonym for `--date=relative`.
 102
 103--date={relative,local,default,iso,rfc}::
 104
 105        Only takes effect for dates shown in human-readable format, such
 106        as when using "--pretty".
 107+
 108`--date=relative` shows dates relative to the current time,
 109e.g. "2 hours ago".
 110+
 111`--date=local` shows timestamps in user's local timezone.
 112+
 113`--date=iso` (or `--date=iso8601`) shows timestamps in ISO 8601 format.
 114+
 115`--date=rfc` (or `--date=rfc2822`) shows timestamps in RFC 2822
 116format, often found in E-mail messages.
 117+
 118`--date=short` shows only date but not time, in `YYYY-MM-DD` format.
 119+
 120`--date=default` shows timestamps in the original timezone
 121(either committer's or author's).
 122
 123--header::
 124
 125        Print the contents of the commit in raw-format; each record is
 126        separated with a NUL character.
 127
 128--parents::
 129
 130        Print the parents of the commit.
 131
 132--timestamp::
 133        Print the raw commit timestamp.
 134
 135--left-right::
 136
 137        Mark which side of a symmetric diff a commit is reachable from.
 138        Commits from the left side are prefixed with `<` and those from
 139        the right with `>`.  If combined with `--boundary`, those
 140        commits are prefixed with `-`.
 141+
 142For example, if you have this topology:
 143+
 144-----------------------------------------------------------------------
 145             y---b---b  branch B
 146            / \ /
 147           /   .
 148          /   / \
 149         o---x---a---a  branch A
 150-----------------------------------------------------------------------
 151+
 152you would get an output line this:
 153+
 154-----------------------------------------------------------------------
 155        $ git rev-list --left-right --boundary --pretty=oneline A...B
 156
 157        >bbbbbbb... 3rd on b
 158        >bbbbbbb... 2nd on b
 159        <aaaaaaa... 3rd on a
 160        <aaaaaaa... 2nd on a
 161        -yyyyyyy... 1st on b
 162        -xxxxxxx... 1st on a
 163-----------------------------------------------------------------------
 164
 165Diff Formatting
 166~~~~~~~~~~~~~~~
 167
 168Below are listed options that control the formatting of diff output.
 169Some of them are specific to gitlink:git-rev-list[1], however other diff
 170options may be given. See gitlink:git-diff-files[1] for more options.
 171
 172-c::
 173
 174        This flag changes the way a merge commit is displayed.  It shows
 175        the differences from each of the parents to the merge result
 176        simultaneously instead of showing pairwise diff between a parent
 177        and the result one at a time. Furthermore, it lists only files
 178        which were modified from all parents.
 179
 180--cc::
 181
 182        This flag implies the '-c' options and further compresses the
 183        patch output by omitting hunks that show differences from only
 184        one parent, or show the same change from all but one parent for
 185        an Octopus merge.
 186
 187-r::
 188
 189        Show recursive diffs.
 190
 191-t::
 192
 193        Show the tree objects in the diff output. This implies '-r'.
 194
 195Commit Limiting
 196~~~~~~~~~~~~~~~
 197
 198Besides specifying a range of commits that should be listed using the
 199special notations explained in the description, additional commit
 200limiting may be applied.
 201
 202--
 203
 204-n 'number', --max-count='number'::
 205
 206        Limit the number of commits output.
 207
 208--skip='number'::
 209
 210        Skip 'number' commits before starting to show the commit output.
 211
 212--since='date', --after='date'::
 213
 214        Show commits more recent than a specific date.
 215
 216--until='date', --before='date'::
 217
 218        Show commits older than a specific date.
 219
 220--max-age='timestamp', --min-age='timestamp'::
 221
 222        Limit the commits output to specified time range.
 223
 224--author='pattern', --committer='pattern'::
 225
 226        Limit the commits output to ones with author/committer
 227        header lines that match the specified pattern (regular expression).
 228
 229--grep='pattern'::
 230
 231        Limit the commits output to ones with log message that
 232        matches the specified pattern (regular expression).
 233
 234-i, --regexp-ignore-case::
 235
 236        Match the regexp limiting patterns without regard to letters case.
 237
 238-E, --extended-regexp::
 239
 240        Consider the limiting patterns to be extended regular expressions
 241        instead of the default basic regular expressions.
 242
 243--remove-empty::
 244
 245        Stop when a given path disappears from the tree.
 246
 247--full-history::
 248
 249        Show also parts of history irrelevant to current state of a given
 250        path. This turns off history simplification, which removed merges
 251        which didn't change anything at all at some child. It will still actually
 252        simplify away merges that didn't change anything at all into either
 253        child.
 254
 255--no-merges::
 256
 257        Do not print commits with more than one parent.
 258
 259--not::
 260
 261        Reverses the meaning of the '{caret}' prefix (or lack thereof)
 262        for all following revision specifiers, up to the next '--not'.
 263
 264--all::
 265
 266        Pretend as if all the refs in `$GIT_DIR/refs/` are listed on the
 267        command line as '<commit>'.
 268
 269--stdin::
 270
 271        In addition to the '<commit>' listed on the command
 272        line, read them from the standard input.
 273
 274--quiet::
 275
 276        Don't print anything to standard output.  This form of
 277        git-rev-list is primarly meant to allow the caller to
 278        test the exit status to see if a range of objects is fully
 279        connected (or not).  It is faster than redirecting stdout
 280        to /dev/null as the output does not have to be formatted.
 281
 282--cherry-pick::
 283
 284        Omit any commit that introduces the same change as
 285        another commit on the "other side" when the set of
 286        commits are limited with symmetric difference.
 287+
 288For example, if you have two branches, `A` and `B`, a usual way
 289to list all commits on only one side of them is with
 290`--left-right`, like the example above in the description of
 291that option.  It however shows the commits that were cherry-picked
 292from the other branch (for example, "3rd on b" may be cherry-picked
 293from branch A).  With this option, such pairs of commits are
 294excluded from the output.
 295
 296-g, --walk-reflogs::
 297
 298        Instead of walking the commit ancestry chain, walk
 299        reflog entries from the most recent one to older ones.
 300        When this option is used you cannot specify commits to
 301        exclude (that is, '{caret}commit', 'commit1..commit2',
 302        nor 'commit1...commit2' notations cannot be used).
 303+
 304With '\--pretty' format other than oneline (for obvious reasons),
 305this causes the output to have two extra lines of information
 306taken from the reflog.  By default, 'commit@\{Nth}' notation is
 307used in the output.  When the starting commit is specified as
 308'commit@{now}', output also uses 'commit@\{timestamp}' notation
 309instead.  Under '\--pretty=oneline', the commit message is
 310prefixed with this information on the same line.
 311
 312Cannot be combined with '\--reverse'.
 313
 314--merge::
 315
 316        After a failed merge, show refs that touch files having a
 317        conflict and don't exist on all heads to merge.
 318
 319--boundary::
 320
 321        Output uninteresting commits at the boundary, which are usually
 322        not shown.
 323
 324--dense, --sparse::
 325
 326When optional paths are given, the default behaviour ('--dense') is to
 327only output commits that changes at least one of them, and also ignore
 328merges that do not touch the given paths.
 329
 330Use the '--sparse' flag to makes the command output all eligible commits
 331(still subject to count and age limitation), but apply merge
 332simplification nevertheless.
 333
 334--bisect::
 335
 336Limit output to the one commit object which is roughly halfway between
 337the included and excluded commits. Thus, if
 338
 339-----------------------------------------------------------------------
 340        $ git-rev-list --bisect foo ^bar ^baz
 341-----------------------------------------------------------------------
 342
 343outputs 'midpoint', the output of the two commands
 344
 345-----------------------------------------------------------------------
 346        $ git-rev-list foo ^midpoint
 347        $ git-rev-list midpoint ^bar ^baz
 348-----------------------------------------------------------------------
 349
 350would be of roughly the same length.  Finding the change which
 351introduces a regression is thus reduced to a binary search: repeatedly
 352generate and test new 'midpoint's until the commit chain is of length
 353one.
 354
 355--bisect-vars::
 356
 357This calculates the same as `--bisect`, but outputs text ready
 358to be eval'ed by the shell. These lines will assign the name of
 359the midpoint revision to the variable `bisect_rev`, and the
 360expected number of commits to be tested after `bisect_rev` is
 361tested to `bisect_nr`, the expected number of commits to be
 362tested if `bisect_rev` turns out to be good to `bisect_good`,
 363the expected number of commits to be tested if `bisect_rev`
 364turns out to be bad to `bisect_bad`, and the number of commits
 365we are bisecting right now to `bisect_all`.
 366
 367--bisect-all::
 368
 369This outputs all the commit objects between the included and excluded
 370commits, ordered by their distance to the included and excluded
 371commits. The farthest from them is displayed first. (This is the only
 372one displayed by `--bisect`.)
 373
 374This is useful because it makes it easy to choose a good commit to
 375test when you want to avoid to test some of them for some reason (they
 376may not compile for example).
 377
 378This option can be used along with `--bisect-vars`, in this case,
 379after all the sorted commit objects, there will be the same text as if
 380`--bisect-vars` had been used alone.
 381
 382--
 383
 384Commit Ordering
 385~~~~~~~~~~~~~~~
 386
 387By default, the commits are shown in reverse chronological order.
 388
 389--topo-order::
 390
 391        This option makes them appear in topological order (i.e.
 392        descendant commits are shown before their parents).
 393
 394--date-order::
 395
 396        This option is similar to '--topo-order' in the sense that no
 397        parent comes before all of its children, but otherwise things
 398        are still ordered in the commit timestamp order.
 399
 400--reverse::
 401
 402        Output the commits in reverse order.
 403        Cannot be combined with '\--walk-reflogs'.
 404
 405Object Traversal
 406~~~~~~~~~~~~~~~~
 407
 408These options are mostly targeted for packing of git repositories.
 409
 410--objects::
 411
 412        Print the object IDs of any object referenced by the listed
 413        commits.  'git-rev-list --objects foo ^bar' thus means "send me
 414        all object IDs which I need to download if I have the commit
 415        object 'bar', but not 'foo'".
 416
 417--objects-edge::
 418
 419        Similar to '--objects', but also print the IDs of excluded
 420        commits prefixed with a "-" character.  This is used by
 421        gitlink:git-pack-objects[1] to build "thin" pack, which records
 422        objects in deltified form based on objects contained in these
 423        excluded commits to reduce network traffic.
 424
 425--unpacked::
 426
 427        Only useful with '--objects'; print the object IDs that are not
 428        in packs.
 429
 430--no-walk::
 431
 432        Only show the given revs, but do not traverse their ancestors.
 433
 434--do-walk::
 435
 436        Overrides a previous --no-walk.
