23 .Sh SYNOPSIS
24 .Nm
25 .Op Fl hV
26 .Ar command
27 .Op Ar arg ...
28 .Sh DESCRIPTION
29 .Nm
30 is a version control system which stores the history of tracked files
31 in a Git repository, as used by the Git version control system.
32 This repository format is described in
33 .Xr git-repository 5 .
34 .Pp
35 .Nm
36 is a
37 .Dq distributed
38 version control system because every copy of a repository is writeable.
39 Modifications made to files can be synchronized between repositories
40 at any time.
41 .Pp
42 Files managed by
43 .Nm
44 must be checked out from the repository for modification.
45 Checked out files are stored in a
46 .Em work tree
47 which can be placed at an arbitrary directory in the filesystem hierarchy.
48 The on-disk format of this work tree is described in
49 .Xr got-worktree 5 .
50 .Pp
51 .Nm
52 provides global and command-specific options.
53 Global options must precede the command name, and are as follows:
54 .Bl -tag -width tenletters
55 .It Fl h
56 Display usage information and exit immediately.
57 .It Fl V , -version
58 Display program version and exit immediately.
59 .El
60 .Pp
61 The commands for
62 .Nm
63 are as follows:
64 .Bl -tag -width checkout
65 .Tg im
66 .It Xo
67 .Cm import
68 .Op Fl b Ar branch
69 .Op Fl I Ar pattern
70 .Op Fl m Ar message
71 .Op Fl r Ar repository-path
72 .Ar directory
73 .Xc
74 .Dl Pq alias: Cm im
75 Create an initial commit in a repository from the file hierarchy
76 within the specified
77 .Ar directory .
78 The created commit will not have any parent commits, i.e. it will be a
79 root commit.
80 Also create a new reference which provides a branch name for the newly
81 created commit.
82 Show the path of each imported file to indicate progress.
83 .Pp
84 The
85 .Cm got import
86 command requires the
87 .Ev GOT_AUTHOR
88 environment variable to be set,
89 unless an author has been configured in
90 .Xr got.conf 5
91 or Git's
92 .Dv user.name
93 and
94 .Dv user.email
95 configuration settings can be obtained from the repository's
96 .Pa .git/config
97 file or from Git's global
98 .Pa ~/.gitconfig
99 configuration file.
100 .Pp
101 The options for
102 .Cm got import
103 are as follows:
104 .Bl -tag -width Ds
105 .It Fl b Ar branch
106 Create the specified
107 .Ar branch .
108 If this option is not specified, a branch corresponding to the repository's
109 HEAD reference will be used.
110 Use of this option is required if the branch resolved via the repository's
111 HEAD reference already exists.
112 .It Fl I Ar pattern
113 Ignore files or directories with a name which matches the specified
114 .Ar pattern .
115 This option may be specified multiple times to build a list of ignore patterns.
116 The
117 .Ar pattern
118 follows the globbing rules documented in
119 .Xr glob 7 .
120 .It Fl m Ar message
121 Use the specified log message when creating the new commit.
122 Without the
123 .Fl m
124 option,
125 .Cm got import
126 opens a temporary file in an editor where a log message can be written.
127 .It Fl r Ar repository-path
128 Use the repository at the specified path.
129 If not specified, assume the repository is located at or above the current
130 working directory.
131 .El
132 .Tg cl
133 .It Xo
134 .Cm clone
135 .Op Fl almqv
136 .Op Fl b Ar branch
137 .Op Fl R Ar reference
138 .Ar repository-URL
139 .Op Ar directory
140 .Xc
141 .Dl Pq alias: Cm cl
142 Clone a Git repository at the specified
143 .Ar repository-URL
144 into the specified
145 .Ar directory .
146 If no
147 .Ar directory
148 is specified, the directory name will be derived from the name of the
149 cloned repository.
150 .Cm got clone
151 will refuse to run if the
152 .Ar directory
153 already exists.
154 .Pp
155 The
156 .Ar repository-URL
157 specifies a protocol scheme, a server hostname, an optional port number
158 separated from the hostname by a colon, and a path to the repository on
159 the server:
160 .Lk scheme://hostname:port/path/to/repository
161 .Pp
162 The following protocol schemes are supported:
163 .Bl -tag -width git+ssh
164 .It git
165 The Git protocol as implemented by the
166 .Xr git-daemon 1
167 server.
168 Use of this protocol is discouraged since it supports neither authentication
169 nor encryption.
170 .It git+ssh
171 The Git protocol wrapped in an authenticated and encrypted
172 .Xr ssh 1
173 tunnel.
174 With this protocol the hostname may contain an embedded username for
175 .Xr ssh 1
176 to use:
177 .Mt user@hostname
178 .It ssh
179 Short alias for git+ssh.
180 .El
181 .Pp
182 Objects in the cloned repository are stored in a pack file which is downloaded
183 from the server.
184 This pack file will then be indexed to facilitate access to the objects stored
185 within.
186 If any objects in the pack file are stored in deltified form, all deltas will
187 be fully resolved in order to compute the ID of such objects.
188 This can take some time.
189 More details about the pack file format are documented in
190 .Xr git-repository 5 .
191 .Pp
192 .Cm got clone
193 creates a remote repository entry in the
194 .Xr got.conf 5
195 and
196 .Pa config
197 files of the cloned repository to store the
198 .Ar repository-url
199 and any
200 .Ar branch
201 or
202 .Ar reference
203 arguments for future use by
204 .Cm got fetch
205 or
206 .Xr git-fetch 1 .
207 .Pp
208 The options for
209 .Cm got clone
210 are as follows:
211 .Bl -tag -width Ds
212 .It Fl a
213 Fetch all branches from the remote repository's
214 .Dq refs/heads/
215 reference namespace and set
216 .Cm fetch_all_branches
217 in the cloned repository's
218 .Xr got.conf 5
219 file for future use by
220 .Cm got fetch .
221 If this option is not specified, a branch resolved via the remote
222 repository's HEAD reference will be fetched.
223 Cannot be used together with the
224 .Fl b
225 option.
226 .It Fl b Ar branch
227 Fetch the specified
228 .Ar branch
229 from the remote repository's
230 .Dq refs/heads/
231 reference namespace.
232 This option may be specified multiple times to build a list of branches
233 to fetch.
234 If the branch corresponding to the remote repository's HEAD reference is not
235 in this list, the cloned repository's HEAD reference will be set to the first
236 branch which was fetched.
237 If this option is not specified, a branch resolved via the remote
238 repository's HEAD reference will be fetched.
239 Cannot be used together with the
240 .Fl a
241 option.
242 .It Fl l
243 List branches and tags available for fetching from the remote repository
244 and exit immediately.
245 Cannot be used together with any of the other options except
246 .Fl q
247 and
248 .Fl v .
249 .It Fl m
250 Create the cloned repository as a mirror of the original repository.
251 This is useful if the cloned repository will not be used to store
252 locally created commits.
253 .Pp
254 The repository's
255 .Xr got.conf 5
256 and
257 .Pa config
258 files will be set up with the
259 .Dq mirror
260 option enabled, such that
261 .Cm got fetch
262 or
263 .Xr git-fetch 1
264 will write incoming changes directly to branches in the
265 .Dq refs/heads/
266 reference namespace, rather than to branches in the
267 .Dq refs/remotes/
268 namespace.
269 This avoids the usual requirement of having to run
270 .Cm got rebase
271 after
272 .Cm got fetch
273 in order to make incoming changes appear on branches in the
274 .Dq refs/heads/
275 namespace.
276 But maintaining custom changes in the cloned repository becomes difficult
277 since such changes will be at risk of being discarded whenever incoming
278 changes are fetched.
279 .It Fl q
280 Suppress progress reporting output.
281 The same option will be passed to
282 .Xr ssh 1
283 if applicable.
284 .It Fl R Ar reference
285 In addition to the branches and tags that will be fetched, fetch an arbitrary
286 .Ar reference
287 from the remote repository's
288 .Dq refs/
289 namespace.
290 This option may be specified multiple times to build a list of additional
291 references to fetch.
292 The specified
293 .Ar reference
294 may either be a path to a specific reference, or a reference namespace
295 which will cause all references in this namespace to be fetched.
296 .Pp
297 Each reference will be mapped into the cloned repository's
298 .Dq refs/remotes/
299 namespace, unless the
300 .Fl m
301 option is used to mirror references directly into the cloned repository's
302 .Dq refs/
303 namespace.
304 .Pp
305 .Cm got clone
306 will refuse to fetch references from the remote repository's
307 .Dq refs/remotes/
308 or
309 .Dq refs/got/
310 namespace.
311 .It Fl v
312 Verbose mode.
313 Causes
314 .Cm got clone
315 to print debugging messages to standard error output.
316 This option will be passed to
317 .Xr ssh 1
318 if applicable.
319 Multiple -v options increase the verbosity.
320 The maximum is 3.

332 Fetch new changes from a remote repository.
333 If no
334 .Ar remote-repository
335 is specified,
336 .Dq origin
337 will be used.
338 The remote repository's URL is obtained from the corresponding entry in
339 .Xr got.conf 5
340 or Git's
341 .Pa config
342 file of the local repository, as created by
343 .Cm got clone .
344 .Pp
345 New changes will be stored in a separate pack file downloaded from the server.
346 Optionally, separate pack files stored in the repository can be combined with
347 .Xr git-repack 1 .
348 .Pp
349 By default, branch references in the
350 .Dq refs/remotes/
351 reference namespace will be updated to point at the newly fetched commits.
352 The
353 .Cm got rebase
354 command can then be used to make new changes visible on branches in the
355 .Dq refs/heads/
356 namespace, merging incoming changes with the changes on those branches
357 as necessary.
358 .Pp
359 If the repository was created as a mirror with
360 .Cm got clone -m ,
361 then all branches in the
362 .Dq refs/heads/
363 namespace will be updated directly to match the corresponding branches in
364 the remote repository.
365 If those branches contained local commits, these commits will no longer be
366 reachable via a reference and will therefore be at risk of being discarded
367 by Git's garbage collector or
368 .Cm gotadmin cleanup .
369 Maintaining custom changes in a mirror repository is therefore discouraged.
370 .Pp
371 In any case, references in the
372 .Dq refs/tags/
373 namespace will always be fetched and mapped directly to local references
374 in the same namespace.
375 .Pp
376 The options for
377 .Cm got fetch
378 are as follows:
379 .Bl -tag -width Ds
380 .It Fl a
381 Fetch all branches from the remote repository's
382 .Dq refs/heads/
383 reference namespace.
384 This option can be enabled by default for specific repositories in
385 .Xr got.conf 5 .
386 If this option is not specified, a branch resolved via the remote
387 repository's HEAD reference will be fetched.
388 Cannot be used together with the
389 .Fl b
390 option.
391 .It Fl b Ar branch
392 Fetch the specified
393 .Ar branch
394 from the remote repository's
395 .Dq refs/heads/
396 reference namespace.
397 This option may be specified multiple times to build a list of branches
398 to fetch.
399 If this option is not specified, a branch resolved via the remote
400 repository's HEAD reference will be fetched.
401 Cannot be used together with the
402 .Fl a
403 option.
404 .It Fl d
405 Delete branches and tags from the local repository which are no longer
406 present in the remote repository.
407 Only references are deleted.
408 Any commit, tree, tag, and blob objects belonging to deleted branches or
409 tags remain in the repository and may be removed separately with
410 Git's garbage collector or
411 .Cm gotadmin cleanup .
412 .It Fl l
413 List branches and tags available for fetching from the remote repository
414 and exit immediately.
415 Cannot be used together with any of the other options except
416 .Fl v ,
417 .Fl q ,
418 and
419 .Fl r .
420 .It Fl q
421 Suppress progress reporting output.
422 The same option will be passed to
423 .Xr ssh 1
424 if applicable.
425 .It Fl R Ar reference
426 In addition to the branches and tags that will be fetched, fetch an arbitrary
427 .Ar reference
428 from the remote repository's
429 .Dq refs/
430 namespace.
431 This option may be specified multiple times to build a list of additional
432 references to fetch.
433 The specified
434 .Ar reference
435 may either be a path to a specific reference, or a reference namespace
436 which will cause all references in this namespace to be fetched.
437 .Pp
438 Each reference will be mapped into the local repository's
439 .Dq refs/remotes/
440 namespace, unless the local repository was created as a mirror with
441 .Cm got clone -m
442 in which case references will be mapped directly into the local repository's
443 .Dq refs/
444 namespace.
445 .Pp
446 Once a reference has been fetched, a branch based on it can be created with
447 .Cm got branch
448 if needed.
449 .Pp
450 .Cm got fetch
451 will refuse to fetch references from the remote repository's
452 .Dq refs/remotes/
453 or
454 .Dq refs/got/
455 namespace.
456 .It Fl r Ar repository-path
457 Use the repository at the specified path.
458 If not specified, assume the repository is located at or above the current
459 working directory.
460 If this directory is a
461 .Nm
462 work tree, use the repository path associated with this work tree.
463 .It Fl t
464 Allow existing references in the
465 .Dq refs/tags
466 namespace to be updated if they have changed on the server.
467 If not specified, only new tag references will be created.
468 .It Fl v
469 Verbose mode.
470 Causes
471 .Cm got fetch
472 to print debugging messages to standard error output.
473 The same option will be passed to
474 .Xr ssh 1
475 if applicable.
476 Multiple -v options increase the verbosity.
477 The maximum is 3.
478 .It Fl X
479 Delete all references which correspond to a particular
480 .Ar remote-repository
481 instead of fetching new changes.
482 This can be useful when a remote repository is being removed from
483 .Xr got.conf 5 .
484 .Pp
485 With
486 .Fl X ,
487 the
488 .Ar remote-repository
489 argument is mandatory and no other options except
490 .Fl r ,
491 .Fl v ,
492 and
493 .Fl q
494 are allowed.
495 .Pp
496 Only references are deleted.
497 Any commit, tree, tag, and blob objects fetched from a remote repository
498 will generally be stored in pack files and may be removed separately with
499 .Xr git-repack 1

528 .Pp
529 The options for

531 are as follows:
532 .Bl -tag -width Ds
533 .It Fl b Ar branch
534 Check out files from a commit on the specified
535 .Ar branch .
536 If this option is not specified, a branch resolved via the repository's HEAD
537 reference will be used.
538 .It Fl c Ar commit
539 Check out files from the specified
540 .Ar commit
541 on the selected branch.
542 The expected argument is a commit ID SHA1 hash or an existing reference
543 or tag name which will be resolved to a commit ID.
544 An abbreviated hash argument will be expanded to a full SHA1 hash
545 automatically, provided the abbreviation is unique.
546 If this option is not specified, the most recent commit on the selected
547 branch will be used.
548 .Pp
549 If the specified
550 .Ar commit
551 is not contained in the selected branch, a different branch which contains
552 this commit must be specified with the
553 .Fl b
554 option.
555 If no such branch is known, a new branch must be created for this
556 commit with
557 .Cm got branch
558 before
559 .Cm got checkout
560 can be used.

591 Files which already contain merge conflicts will not be updated to avoid
592 further complications.
593 Such files will be updated when
594 .Cm got update
595 is run again after merge conflicts have been resolved.
596 If the conflicting changes are no longer needed, affected files can be
597 reverted with
598 .Cm got revert
599 before running
600 .Cm got update
601 again.
602 .Pp
603 Show the status of each affected file, using the following status codes:

614 .El
615 .Pp
616 If no
617 .Ar path
618 is specified, update the entire work tree.
619 Otherwise, restrict the update operation to files at or within the
620 specified paths.
621 Each path is required to exist in the update operation's target commit.
622 Files in the work tree outside specified paths will remain unchanged and
623 will retain their previously recorded base commit.
624 Some
625 .Nm
626 commands may refuse to run while the work tree contains files from
627 multiple base commits.
628 The base commit of such a work tree can be made consistent by running
629 .Cm got update
630 across the entire work tree.
631 Specifying a
632 .Ar path
633 is incompatible with the
634 .Fl b
635 option.
636 .Pp
637 .Cm got update
638 cannot update paths with staged changes.
639 If changes have been staged with
640 .Cm got stage ,
641 these changes must first be committed with
642 .Cm got commit
643 or unstaged with
644 .Cm got unstage .
645 .Pp
646 The options for
647 .Cm got update
648 are as follows:
649 .Bl -tag -width Ds
650 .It Fl b Ar branch
651 Switch the work tree's branch reference to the specified
652 .Ar branch
653 before updating the work tree.
654 This option requires that all paths in the work tree are updated.
655 .Pp
656 As usual, any local changes in the work tree will be preserved.
657 This can be useful when switching to a newly created branch in order
658 to commit existing local changes to this branch.
659 .Pp
660 Any local changes must be dealt with separately in order to obtain a
661 work tree with pristine file contents corresponding exactly to the specified
662 .Ar branch .
663 Such changes could first be committed to a different branch with
664 .Cm got commit ,
665 or could be discarded with
666 .Cm got revert .
667 .It Fl c Ar commit
668 Update the work tree to the specified
669 .Ar commit .
670 The expected argument is a commit ID SHA1 hash or an existing reference
671 or tag name which will be resolved to a commit ID.

1300 .Ar commit .
1301 The expected
1302 .Ar commit
1303 argument is a commit ID SHA1 hash or an existing reference or tag name which
1304 will be resolved to a commit ID.
1305 An abbreviated hash argument will be expanded to a full SHA1 hash
1306 automatically, provided the abbreviation is unique.
1307 .It Fl l
1308 List all existing tags in the repository instead of creating a new tag.
1309 If a
1310 .Ar name
1311 argument is passed, show only the tag with the given
1312 .Ar name .
1313 .It Fl m Ar message
1314 Use the specified tag message when creating the new tag.
1315 Without the
1316 .Fl m
1317 option,
1318 .Cm got tag
1319 opens a temporary file in an editor where a tag message can be written.
1320 .It Fl r Ar repository-path
1321 Use the repository at the specified path.
1322 If not specified, assume the repository is located at or above the current
1323 working directory.
1324 If this directory is a
1325 .Nm
1326 work tree, use the repository path associated with this work tree.
1327 .It Fl s Ar signer-id
1328 While creating a new tag, sign this tag with the identity given in
1329 .Ar signer-id .
1330 .Pp
1331 For SSH-based signatures,
1332 .Ar signer-id
1333 is the path to a file which may refer to either a private SSH key,
1334 or a public SSH key with the private half available via
1335 .Xr ssh-agent 1 .
1336 .Cm got tag
1337 will sign the tag object by invoking
1338 .Xr ssh-keygen 1
1339 with the
1340 .Fl Y Cm sign
1341 command, using the signature namespace
1342 .Dq git
1343 for compatibility with
1344 .Xr git 1 .
1345 .It Fl V
1346 Verify tag object signatures.
1347 If a
1348 .Ar name
1349 is specified, show and verify the tag object with the provided name.
1350 Otherwise, list all tag objects and verify signatures where present.
1351 .Pp
1352 .Cm got tag
1353 verifies SSH-based signatures by invoking
1354 .Xr ssh-keygen 1
1355 with the options
1356 .Fl Y Cm verify Fl f Ar allowed_signers .
1357 A path to the
1358 .Ar allowed_signers
1359 file must be set in
1360 .Xr got.conf 5 ,
1361 otherwise verification is impossible.
1362 .It Fl v
1363 Verbose mode.
1364 During SSH signature creation and verification this option will be passed to
1365 .Xr ssh-keygen 1 .
1366 Multiple -v options increase the verbosity.
1367 The maximum is 3.
1368 .El
1369 .Pp
1370 By design, the
1371 .Cm got tag
1372 command will not delete tags or change existing tags.
1373 If a tag must be deleted, the
1374 .Cm got ref
1375 command may be used to delete a tag's reference.
1376 This should only be done if the tag has not already been copied to

1507 Any changes made to the work tree up to this point will be left behind.
1508 Such changes can be viewed with
1509 .Cm got diff
1510 and can be reverted with
1511 .Cm got revert
1512 if needed.

1518 .It Fl c Ar commit
1519 Attempt to locate files within the specified
1520 .Ar commit
1521 for use as a merge-base for 3-way merges.
1522 Ideally, the specified
1523 .Ar commit
1524 should contain versions of files which the changes contained in the
1525 .Ar patchfile
1526 were based on.
1527 Files will be located by path, relative to the repository root.
1528 If the
1529 .Fl p
1530 option is used then leading path components will be stripped
1531 before paths are looked up in the repository.
1532 .Pp
1533 If the
1534 .Fl c
1535 option is not used then
1536 .Cm got patch
1537 will attempt to locate merge-bases via object IDs found in
1538 .Ar patchfile
1539 meta-data, such as produced by
1540 .Cm got diff
1542 .Xr git-diff 1 .
1543 Use of the
1544 .Fl c
1545 option is only recommended in the absence of such meta-data.
1546 .Pp
1547 In case no merge-base is available for a file, changes will be applied
1548 without doing a 3-way merge.
1549 Changes which do not apply cleanly may then be rejected entirely, rather
1550 than producing merge conflicts in the patched target file.
1551 .It Fl n
1552 Do not make any modifications to the work tree.
1553 This can be used to check whether a patch would apply without issues.
1554 If the
1555 .Ar patchfile
1556 contains diffs that affect the same file multiple times, the results
1557 displayed may be incorrect.
1558 .It Fl p Ar strip-count
1559 Specify the number of leading path components to strip from paths

1676 multiple base commits.
1677 The base commit of such a work tree can be made consistent by running
1678 .Cm got update
1679 across the entire work tree.
1680 .Pp
1681 The

1706 This is useful when committing changes which were written by someone
1707 else.
1708 The
1709 .Ar author
1710 argument must use the same format as the
1711 .Ev GOT_AUTHOR
1712 environment variable.
1713 .Pp
1714 In addition to storing author information, the newly created commit
1715 object will retain

1737 .It Fl N
1738 This option prevents
1739 .Cm got commit
1740 from opening the commit message in an editor.
1741 It has no effect unless it is used together with the
1742 .Fl F
1743 option and is intended for non-interactive use such as scripting.
1744 .It Fl n
1745 This option prevents
1746 .Cm got commit
1747 from generating a diff of the to-be-committed changes in a temporary file
1748 which can be viewed while editing a commit message.
1749 .It Fl S
1750 Allow the addition of symbolic links which point outside of the path space
1751 that is under version control.
1752 By default,
1753 .Cm got commit
1754 will reject such symbolic links due to safety concerns.
1755 As a precaution,
1756 .Nm
1757 may decide to represent such a symbolic link as a regular file which contains
1758 the link's target path, rather than creating an actual symbolic link which
1759 points outside of the work tree.
1760 Use of this option is discouraged because external mechanisms such as
1761 .Dq make obj
1762 are better suited for managing symbolic links to paths not under
1763 version control.

1805 reference namespace of the local repository will be updated to point at
1806 the commits which have been sent.
1807 .Pp
1808 By default, changes will only be sent if they are based on up-to-date
1809 copies of relevant branches in the remote repository.
1810 If any changes to be sent are based on out-of-date copies or would
1811 otherwise break linear history of existing branches, new changes must
1812 be fetched from the server with
1813 .Cm got fetch
1814 and local branches must be rebased with
1815 .Cm got rebase
1816 before
1817 .Cm got send
1818 can succeed.
1819 The

1845 This option may be specified multiple times to build a list of branches
1846 to send.
1847 If this option is not specified, default to the work tree's current branch
1848 if invoked in a work tree, or to the repository's HEAD reference.
1849 Cannot be used together with the

1858 This option may be specified multiple times to build a list of branches
1859 to delete.
1860 .Pp
1861 Only references are deleted.
1862 Any commit, tree, tag, and blob objects belonging to deleted branches
1863 may become subject to deletion by Git's garbage collector running on
1864 the server.
1865 .Pp
1866 Requesting deletion of branches results in an error if the server
1867 does not support this feature or disallows the deletion of branches
1868 based on its configuration.
1869 .It Fl f
1870 Attempt to force the server to overwrite existing branches or tags
1871 in the remote repository, even when
1872 .Cm got fetch
1873 and
1874 .Cm got rebase
1875 would usually be required before changes can be sent.
1876 The server may reject forced requests regardless, depending on its
1877 configuration.
1878 .Pp
1879 Any commit, tree, tag, and blob objects belonging to overwritten branches
1880 or tags may become subject to deletion by Git's garbage collector running
1881 on the server.
1882 .Pp
1883 The
1884 .Dq refs/tags
1885 reference namespace is globally shared between all repositories.
1886 Use of the
1887 .Fl f
1888 option to overwrite tags is discouraged because it can lead to
1889 inconsistencies between the tags present in different repositories.
1890 In general, creating a new tag with a different name is recommended
1891 instead of overwriting an existing tag.
1892 .Pp
1893 Use of the
1894 .Fl f
1895 option is particularly discouraged if changes being sent are based
1896 on an out-of-date copy of a branch in the remote repository.
1897 Instead of using the
1898 .Fl f
1899 option, new changes should
1900 be fetched with
1901 .Cm got fetch
1902 and local branches should be rebased with
1903 .Cm got rebase ,
1904 followed by another attempt to send the changes.
1905 .Pp
1906 The
1907 .Fl f
1908 option should only be needed in situations where the remote repository's
1909 copy of a branch or tag is known to be out-of-date and is considered
1910 disposable.
1911 The risks of creating inconsistencies between different repositories
1912 should also be taken into account.
1913 .It Fl q

2154 The
2155 .Ar branch
2156 must share common ancestry with the work tree's current branch.
2157 Rebasing begins with the first descendant commit of the youngest
2158 common ancestor commit shared by the specified
2159 .Ar branch
2160 and the work tree's current branch, and stops once the tip commit
2161 of the specified
2162 .Ar branch
2163 has been rebased.
2164 .Pp
2165 When
2166 .Cm got rebase
2167 is used as intended, the specified
2168 .Ar branch
2169 represents a local commit history and may already contain changes
2170 that are not yet visible in any other repositories.
2171 The work tree's current branch, which must be set with
2172 .Cm got update -b
2173 before starting the
2174 .Cm rebase
2175 operation, represents a branch from a remote repository which shares
2176 a common history with the specified
2177 .Ar branch
2178 but has progressed, and perhaps diverged, due to commits added to the
2179 remote repository.
2180 .Pp
2181 Rebased commits are accumulated on a temporary branch which the work tree
2182 will remain switched to throughout the entire rebase operation.
2183 Commits on this branch represent the same changes with the same log
2184 messages as their counterparts on the original
2185 .Ar branch ,
2186 but with different commit IDs.
2187 Once rebasing has completed successfully, the temporary branch becomes
2188 the new version of the specified

2190 and the work tree is automatically switched to it.

2204 Old commits in their pre-rebase state are automatically backed up in the

2207 As long as these references are not removed older versions of rebased
2208 commits will remain in the repository and can be viewed with the
2209 .Cm got rebase -l
2210 command.
2211 Removal of these references makes objects which become unreachable via
2212 any reference subject to removal by Git's garbage collector or
2213 .Cm gotadmin cleanup .
2214 .Pp
2215 While rebasing commits, show the status of each affected file,

2228 If merge conflicts occur, the rebase operation is interrupted and may
2229 be continued once conflicts have been resolved.
2230 If any files with destined changes are found to be missing or unversioned,
2231 or if files could not be deleted due to differences in deleted content,
2232 the rebase operation will be interrupted to prevent potentially incomplete
2233 changes from being committed to the repository without user intervention.
2234 The work tree may be modified as desired and the rebase operation can be
2235 continued once the changes present in the work tree are considered complete.
2236 Alternatively, the rebase operation may be aborted which will leave
2237 .Ar branch
2238 unmodified and the work tree switched back to its original branch.
2239 .Pp
2240 If a merge conflict is resolved in a way which renders the merged
2241 change into a no-op change, the corresponding commit will be elided
2242 when the rebase operation continues.

2384 .Pp
2385 Before starting a
2386 .Cm histedit
2387 operation, the work tree's current branch must be set with
2388 .Cm got update -b
2389 to the branch which should be edited, unless this branch is already the
2390 current branch of the work tree.
2391 The tip of this branch represents the upper bound (inclusive) of commits
2392 touched by the
2393 .Cm histedit
2394 operation.
2395 .Pp
2396 Furthermore, the work tree's base commit
2397 must be set with
2398 .Cm got update -c
2399 to a point in this branch's commit history where editing should begin.
2400 This commit represents the lower bound (non-inclusive) of commits touched
2401 by the

2405 Editing of commit history is controlled via a

2413 .Pp
2414 The format of the histedit script is line-based.
2415 Each line in the script begins with a command name, followed by
2416 whitespace and an argument.
2417 For most commands, the expected argument is a commit ID SHA1 hash.
2418 Any remaining text on the line is ignored.
2419 Lines which begin with the

2425 .It Cm pick Ar commit Ta Use the specified commit as it is.
2426 .It Cm edit Ar commit Ta Use the specified commit but once changes have been

2439 argument provides a new single-line log message to use.

2445 Every commit in the history being edited must be mentioned in the script.
2446 Lines may be re-ordered to change the order of commits in the edited history.
2447 No commit may be listed more than once.
2448 .Pp
2449 Edited commits are accumulated on a temporary branch which the work tree
2450 will remain switched to throughout the entire histedit operation.
2451 Once history editing has completed successfully, the temporary branch becomes
2452 the new version of the work tree's branch and the work tree is automatically

2551 can be written.
2552 .It Fl f
2553 Fold all commits into a single commit.
2554 This option is a quick equivalent to a histedit script which folds all
2555 commits, combining them all into one commit.
2556 The

2566 the object ID of the corresponding post-histedit commit, and
2567 the object ID of their common ancestor commit.
2568 Given these object IDs,
2569 the
2570 .Cm got log
2571 command with the
2572 .Fl c
2573 and
2574 .Fl x
2575 options can be used to examine the history of either version of the branch,
2576 and the
2577 .Cm got branch
2578 command with the

2656 Most importantly, the
2657 .Ar branch
2658 must have been rebased onto the work tree's current branch with
2659 .Cm got rebase
2660 before it can be integrated, in order to linearize commit history and
2661 resolve merge conflicts.
2662 If the work tree contains multiple base commits, it must first be updated
2663 to a single base commit with
2664 .Cm got update .
2665 If changes have been staged with
2666 .Cm got stage ,
2667 these changes must first be committed with

2686 If a linear project history is desired, then use of
2687 .Cm got rebase
2688 should be preferred over
2689 .Cm got merge .
2690 However, even strictly linear projects may require merge commits in order
2691 to merge in new versions of third-party code stored on vendor branches
2692 created with

2694 .Pp
2695 Merge commits are commits based on multiple parent commits.

2698 before starting the
2699 .Cm merge
2700 operation, will be used as the first parent.
2701 The tip commit of the specified
2702 .Ar branch
2703 will be used as the second parent.
2704 .Pp
2705 No ancestral relationship between the two branches is required.
2706 If the two branches have already been merged previously, only new changes
2707 will be merged.
2708 .Pp
2709 It is not possible to create merge commits with more than two parents.
2710 If more than one branch needs to be merged, then multiple merge commits
2711 with two parents each can be created in sequence.

2726 .El
2727 .Pp
2728 If merge conflicts occur, the merge operation is interrupted and conflicts
2729 must be resolved before the merge operation can continue.
2730 If any files with destined changes are found to be missing or unversioned,
2731 or if files could not be deleted due to differences in deleted content,
2732 the merge operation will be interrupted to prevent potentially incomplete
2733 changes from being committed to the repository without user intervention.
2734 The work tree may be modified as desired and the merge can be continued
2735 once the changes present in the work tree are considered complete.
2736 Alternatively, the merge operation may be aborted which will leave
2737 the work tree's current branch unmodified.
2738 .Pp
2739 If a merge conflict is resolved in a way which renders all merged
2740 changes into no-op changes, the merge operation cannot continue
2741 and must be aborted.
2742 .Pp
2743 .Cm got merge
2744 will refuse to run if certain preconditions are not met.
2745 If history of the

2747 is based on the work tree's current branch, then no merge commit can
2748 be created and
2749 .Cm got integrate
2750 may be used to integrate the
2751 .Ar branch
2752 instead.
2753 If the work tree is not yet fully updated to the tip commit of its
2754 branch, then the work tree must first be updated with
2755 .Cm got update .
2756 If the work tree contains multiple base commits, it must first be updated
2757 to a single base commit with

2842 the path is staged again, or if the staged changes are committed first.
2843 The

2897 may decide to represent such a symbolic link as a regular file which contains
2898 the link's target path, rather than creating an actual symbolic link which
2899 points outside of the work tree.
2900 Use of this option is discouraged because external mechanisms such as

3157 Alternatively, for quick and dirty local testing of

3159 a new Git repository could be created and populated with files,
3160 e.g. from a temporary CVS checkout located at
3161 .Pa /tmp/src :
3162 .Pp
3163 .Dl $ gotadmin init /var/git/src.git
3164 .Dl $ got import -r /var/git/src.git -I CVS -I obj /tmp/src
3165 .Pp
3166 Check out a work tree from the Git repository to /usr/src:
3167 .Pp
3168 .Dl $ got checkout /var/git/src.git /usr/src
3169 .Pp
3170 View local changes in a work tree directory:
3171 .Pp
3172 .Dl $ got diff | less
3173 .Pp
3174 In a work tree, display files in a potentially problematic state:
3175 .Pp
3176 .Dl $ got status -s 'C!~?'
3177 .Pp
3178 Interactively revert selected local changes in a work tree directory:
3179 .Pp
3180 .Dl $ got revert -p -R\ .
3181 .Pp
3182 In a work tree or a git repository directory, list all branch references:
3183 .Pp
3184 .Dl $ got branch -l
3185 .Pp
3186 As above, but list the most recently modified branches only:
3187 .Pp
3188 .Dl $ got branch -lt | head
3189 .Pp
3190 In a work tree or a git repository directory, create a new branch called
3191 .Dq unified-buffer-cache
3192 which is forked off the
3193 .Dq master
3194 branch:
3195 .Pp
3196 .Dl $ got branch -c master unified-buffer-cache
3197 .Pp
3198 Switch an existing work tree to the branch
3199 .Dq unified-buffer-cache .
3200 Local changes in the work tree will be preserved and merged if necessary:
3201 .Pp
3202 .Dl $ got update -b unified-buffer-cache
3203 .Pp
3204 Create a new commit from local changes in a work tree directory.
3205 This new commit will become the head commit of the work tree's current branch:
3206 .Pp
3207 .Dl $ got commit
3208 .Pp
3209 In a work tree or a git repository directory, view changes committed in
3210 the 3 most recent commits to the work tree's branch, or the branch resolved
3211 via the repository's HEAD reference, respectively:
3212 .Pp
3213 .Dl $ got log -p -l 3
3214 .Pp
3215 As above, but display changes in the order in which
3216 .Xr patch 1
3217 could apply them in sequence:
3218 .Pp
3219 .Dl $ got log -p -l 3 -R
3220 .Pp
3221 In a work tree or a git repository directory, log the history of a subdirectory:
3222 .Pp
3223 .Dl $ got log sys/uvm
3224 .Pp
3225 While operating inside a work tree, paths are specified relative to the current
3226 working directory, so this command will log the subdirectory
3227 .Pa sys/uvm :
3228 .Pp
3229 .Dl $ cd sys/uvm && got log\ .
3230 .Pp
3231 And this command has the same effect:
3232 .Pp
3233 .Dl $ cd sys/dev/usb && got log ../../uvm
3234 .Pp
3235 And this command displays work tree meta-data about all tracked files:
3236 .Pp
3237 .Dl $ cd /usr/src
3238 .Dl $ got info\ . | less
3239 .Pp
3240 Add new files and remove obsolete files in a work tree directory:
3241 .Pp
3242 .Dl $ got add sys/uvm/uvm_ubc.c
3243 .Dl $ got remove sys/uvm/uvm_vnode.c
3244 .Pp
3245 Create a new commit from local changes in a work tree directory
3246 with a pre-defined log message.
3247 .Pp
3248 .Dl $ got commit -m 'unify the buffer cache'
3249 .Pp
3250 Alternatively, create a new commit from local changes in a work tree
3251 directory with a log message that has been prepared in the file
3252 .Pa /tmp/msg :
3253 .Pp
3254 .Dl $ got commit -F /tmp/msg
3255 .Pp
3256 Update any work tree checked out from the
3257 .Dq unified-buffer-cache
3258 branch to the latest commit on this branch:
3259 .Pp
3260 .Dl $ got update
3261 .Pp
3262 Roll file content on the unified-buffer-cache branch back by one commit,
3263 and then fetch the rolled-back change into the work tree as a local change
3264 to be amended and perhaps committed again:
3265 .Pp
3266 .Dl $ got backout unified-buffer-cache
3267 .Dl $ got commit -m 'roll back previous'
3268 .Dl $ # now back out the previous backout :-)
3269 .Dl $ got backout unified-buffer-cache
3270 .Pp
3271 Fetch new changes on the remote repository's

3275 branch:
3276 .Pp
3277 .Dl $ cd /usr/src
3278 .Dl $ got fetch
3279 .Pp
3280 In a repository created with a HTTP URL and
3281 .Cm git clone --bare
3282 the
3283 .Xr git-fetch 1
3284 command must be used instead:
3285 .Pp
3286 .Dl $ cd /var/git/src.git
3287 .Dl $ git fetch origin master:refs/remotes/origin/master
3288 .Pp
3289 Rebase the local
3290 .Dq master
3291 branch to merge the new changes that are now visible on the
3292 .Dq origin/master
3293 branch:
3294 .Pp
3295 .Dl $ cd /usr/src
3296 .Dl $ got update -b origin/master
3297 .Dl $ got rebase master
3298 .Pp
3299 Rebase the
3300 .Dq unified-buffer-cache
3301 branch on top of the new head commit of the
3302 .Dq master
3303 branch.
3304 .Pp
3305 .Dl $ got update -b master
3306 .Dl $ got rebase unified-buffer-cache
3307 .Pp
3308 Create a patch from all changes on the unified-buffer-cache branch.
3309 The patch can be mailed out for review and applied to
3310 .Ox Ns 's
3311 CVS tree:
3312 .Pp
3313 .Dl $ got diff master unified-buffer-cache > /tmp/ubc.diff
3314 .Pp
3315 Edit the entire commit history of the
3316 .Dq unified-buffer-cache
3317 branch:
3318 .Pp
3319 .Dl $ got update -b unified-buffer-cache
3320 .Dl $ got update -c master
3321 .Dl $ got histedit
3322 .Pp
3323 Before working against existing branches in a repository cloned with
3324 .Cm git clone --bare
3325 instead of
3326 .Cm got clone ,
3327 a Git
3328 .Dq refspec
3329 must be configured to map all references in the remote repository
3330 into the
3331 .Dq refs/remotes
3332 namespace of the local repository.
3333 This can be achieved by setting Git's
3334 .Pa remote.origin.fetch
3335 configuration variable to the value
3336 .Dq +refs/heads/*:refs/remotes/origin/*
3337 with the
3338 .Cm git config
3339 command:
3340 .Pp
3341 .Dl $ cd /var/git/repo
3342 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
3343 .Pp
3344 Additionally, the
3345 .Dq mirror
3346 option must be disabled:
3347 .Pp
3348 .Dl $ cd /var/git/repo
3349 .Dl $ git config remote.origin.mirror false
3350 .Pp
3351 Alternatively, the following
3352 .Xr git-fetch 1
3353 configuration item can be added manually to the Git repository's
3354 .Pa config
3355 file:
3356 .Pp
3357 .Dl [remote \&"origin\&"]
3358 .Dl url = ...
3359 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
3360 .Dl mirror = false
3361 .Pp
3362 This configuration leaves the local repository's
3363 .Dq refs/heads
3364 namespace free for use by local branches checked out with
3365 .Cm got checkout
3366 and, if needed, created with
3367 .Cm got branch .
3368 Branches in the
3369 .Dq refs/remotes/origin
3370 namespace can now be updated with incoming changes from the remote
3371 repository with
3372 .Cm got fetch
3374 .Xr git-fetch 1
3375 without extra command line arguments.
3376 Newly fetched changes can be examined with
3377 .Cm got log .
3378 .Pp
3379 Display changes on the remote repository's version of the
3380 .Dq master
3381 branch, as of the last time
3382 .Cm got fetch
3383 was run:
3384 .Pp
3385 .Dl $ got log -c origin/master | less
3386 .Pp
3387 As shown here, most commands accept abbreviated reference names such as
3388 .Dq origin/master
3389 instead of
3390 .Dq refs/remotes/origin/master .
3391 The latter is only needed in case of ambiguity.
3392 .Pp
3393 .Cm got rebase
3394 must be used to merge changes which are visible on the
3395 .Dq origin/master
3396 branch into the
3397 .Dq master
3398 branch.
3399 This will also merge local changes, if any, with the incoming changes:
3400 .Pp
3401 .Dl $ got update -b origin/master
3402 .Dl $ got rebase master
3403 .Pp
3404 In order to make changes committed to the
3405 .Dq unified-buffer-cache
3406 visible on the
3407 .Dq master
3408 branch, the
3409 .Dq unified-buffer-cache
3410 branch must first be rebased onto the
3411 .Dq master
3412 branch:
3413 .Pp
3414 .Dl $ got update -b master
3415 .Dl $ got rebase unified-buffer-cache
3416 .Pp
3417 Changes on the
3418 .Dq unified-buffer-cache
3419 branch can now be made visible on the
3420 .Dq master
3421 branch with
3422 .Cm got integrate .
3423 Because the rebase operation switched the work tree to the
3424 .Dq unified-buffer-cache
3425 branch, the work tree must be switched back to the
3426 .Dq master
3427 branch first:
3428 .Pp
3429 .Dl $ got update -b master
3430 .Dl $ got integrate unified-buffer-cache
3431 .Pp
3432 On the
3433 .Dq master
3434 branch, log messages for local changes can now be amended with
3435 .Dq OK
3436 by other developers and any other important new information:
3437 .Pp
3438 .Dl $ got update -c origin/master
3439 .Dl $ got histedit -m
3440 .Pp
3441 If the remote repository offers write access, local changes on the
3442 .Dq master
3443 branch can be sent to the remote repository with
3444 .Cm got send .
3445 Usually,
3446 .Cm got send
3447 can be run without further arguments.
3448 The arguments shown here match defaults, provided the work tree's
3449 current branch is the
3450 .Dq master
3451 branch:
3452 .Pp
3453 .Dl $ got send -b master origin
3454 .Pp
3455 If the remote repository requires the HTTPS protocol, the
3456 .Xr git-push 1
3457 command must be used instead:
3458 .Pp
3459 .Dl $ cd /var/git/src.git
3460 .Dl $ git push origin master
3461 .Pp
3462 When making contributions to projects which use the
3463 .Dq pull request
3464 workflow, SSH protocol repository access needs to be set up first.
3465 Once an account has been created on a Git hosting site it should
3466 be possible to upload a public SSH key for repository access
3467 authentication.
3468 .Pp
3469 The
3470 .Dq pull request
3471 workflow will usually involve two remote repositories.
3472 In the real-life example below, the
3473 .Dq origin
3474 repository was forked from the
3475 .Dq upstream
3476 repository by using the Git hosting site's web interface.
3477 The
3478 .Xr got.conf 5
3479 file in the local repository describes both remote repositories:
3480 .Bd -literal -offset indent
3481 # Jelmers's repository, which accepts pull requests
3482 remote "upstream" {
3483 server git@github.com
3484 protocol ssh
3485 repository "/jelmer/dulwich"
3486 branch { "master" }
3489 # Stefan's fork, used as the default remote repository
3490 remote "origin" {
3491 server git@github.com
3492 protocol ssh
3493 repository "/stspdotname/dulwich"
3494 branch { "master" }
3496 .Ed
3497 .Pp
3498 With this configuration, Stefan can create commits on
3499 .Dq refs/heads/master
3500 and send them to the
3501 .Dq origin
3502 repository by running:
3503 .Pp
3504 .Dl $ got send -b master origin
3505 .Pp
3506 The changes can now be proposed to Jelmer by opening a pull request
3507 via the Git hosting site's web interface.
3508 If Jelmer requests further changes to be made, additional commits
3509 can be created on the
3510 .Dq master
3511 branch and be added to the pull request by running
3512 .Cd got send
3513 again.
3514 .Pp
3515 If Jelmer prefers additional commits to be
3516 .Dq squashed
3517 then the following commands can be used to achieve this:
3518 .Pp
3519 .Dl $ got update -b master
3520 .Dl $ got update -c origin/master
3521 .Dl $ got histedit -f
3522 .Dl $ got send -f -b master origin
3523 .Pp
3524 Once Jelmer has accepted the pull request, Stefan can fetch the
3525 merged changes, and possibly several other new changes, by running:
3526 .Pp
3527 .Dl $ got fetch upstream
3528 .Pp
3529 The merged changes will now be visible under the reference
3530 .Dq refs/remotes/upstream/master .
3531 The local
3532 .Dq master
3533 branch can now be rebased on top of the latest changes
3534 from upstream:
3535 .Pp
3536 .Dl $ got update -b upstream/master
3537 .Dl $ got rebase master
3538 .Pp
3539 As a final step, the forked repository's copy of the master branch needs
3540 to be kept in sync by sending the new changes there:
3541 .Pp
3542 .Dl $ got send -f -b master origin
3543 .Pp
3544 If multiple pull requests need to be managed in parallel, a separate branch
3545 must be created for each pull request with
3546 .Cm got branch .
3547 Each such branch can then be used as above, in place of
3548 .Dq refs/heads/master .
3549 Changes for any accepted pull requests will still appear under
3550 .Dq refs/remotes/upstream/master,
3551 regardless of which branch was used in the forked repository to
3552 create a pull request.
