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 .It Cm init Ar repository-path
66 Create a new empty repository at the specified
67 .Ar repository-path .
68 .Pp
69 After
70 .Cm got init ,
71 the
72 .Cm got import
73 command must be used to populate the empty repository before
74 .Cm got checkout
75 can be used.
76 .It Cm in
77 Short alias for
78 .Cm init .
79 .It Cm import Oo Fl b Ar branch Oc Oo Fl m Ar message Oc Oo Fl r Ar repository-path Oc Oo Fl I Ar pattern Oc Ar directory
80 Create an initial commit in a repository from the file hierarchy
81 within the specified
82 .Ar directory .
83 The created commit will not have any parent commits, i.e. it will be a
84 root commit.
85 Also create a new reference which provides a branch name for the newly
86 created commit.
87 Show the path of each imported file to indicate progress.
88 .Pp
89 The
90 .Cm got import
91 command requires the
92 .Ev GOT_AUTHOR
93 environment variable to be set,
94 unless Git's
95 .Dv user.name
96 and
97 .Dv user.email
98 configuration settings can be obtained from the repository's
99 .Pa .git/config
100 file or from Git's global
101 .Pa ~/.gitconfig
102 configuration file.
103 .Pp
104 The options for
105 .Cm got import
106 are as follows:
107 .Bl -tag -width Ds
108 .It Fl b Ar branch
109 Create the specified
110 .Ar branch
111 instead of creating the default branch
112 .Dq main .
113 Use of this option is required if the
114 .Dq main
115 branch already exists.
116 .It Fl m Ar message
117 Use the specified log message when creating the new commit.
118 Without the
119 .Fl m
120 option,
121 .Cm got import
122 opens a temporary file in an editor where a log message can be written.
123 .It Fl r Ar repository-path
124 Use the repository at the specified path.
125 If not specified, assume the repository is located at or above the current
126 working directory.
127 .It Fl I Ar pattern
128 Ignore files or directories with a name which matches the specified
129 .Ar pattern .
130 This option may be specified multiple times to build a list of ignore patterns.
131 The
132 .Ar pattern
133 follows the globbing rules documented in
134 .Xr glob 7 .
135 .El
136 .It Cm im
137 Short alias for
138 .Cm import .
139 .It Cm checkout Oo Fl E Oc Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Oo Fl p Ar path-prefix Oc Ar repository-path Op Ar work-tree-path
140 Copy files from a repository into a new work tree.
141 Show the status of each affected file, using the following status codes:
142 .Bl -column YXZ description
143 .It A Ta new file was added
144 .It E Ta file already exists in work tree's meta-data
145 .El
146 .Pp
147 If the
148 .Ar work tree path
149 is not specified, either use the last component of
150 .Ar repository path ,
151 or if a
152 .Ar path prefix
153 was specified use the last component of
154 .Ar path prefix .
155 .Pp
156 The options for
157 .Cm got checkout
158 are as follows:
159 .Bl -tag -width Ds
160 .It Fl E
161 Proceed with the checkout operation even if the directory at
162 .Ar work-tree-path
163 is not empty.
164 Existing files will be left intact.
165 .It Fl b Ar branch
166 Check out files from a commit on the specified
167 .Ar branch .
168 If this option is not specified, a branch resolved via the repository's HEAD
169 reference will be used.
170 .It Fl c Ar commit
171 Check out files from the specified
172 .Ar commit
173 on the selected branch.
174 The expected argument is a commit ID SHA1 hash or an existing reference
175 or tag name which will be resolved to a commit ID.
176 An abbreviated hash argument will be expanded to a full SHA1 hash
177 automatically, provided the abbreviation is unique.
178 If this option is not specified, the most recent commit on the selected
179 branch will be used.
180 .It Fl p Ar path-prefix
181 Restrict the work tree to a subset of the repository's tree hierarchy.
182 Only files beneath the specified
183 .Ar path-prefix
184 will be checked out.
185 .El
186 .It Cm co
187 Short alias for
188 .Cm checkout .
189 .It Cm update Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Op Ar path ...
190 Update an existing work tree to a different commit.
191 Show the status of each affected file, using the following status codes:
192 .Bl -column YXZ description
193 .It U Ta file was updated and contained no local changes
194 .It G Ta file was updated and local changes were merged cleanly
195 .It C Ta file was updated and conflicts occurred during merge
196 .It D Ta file was deleted
197 .It A Ta new file was added
198 .It \(a~ Ta versioned file is obstructed by a non-regular file
199 .It ! Ta a missing versioned file was restored
200 .El
201 .Pp
202 If no
203 .Ar path
204 is specified, update the entire work tree.
205 Otherwise, restrict the update operation to files at or within the
206 specified paths.
207 Each path is required to exist in the update operation's target commit.
208 Files in the work tree outside specified paths will remain unchanged and
209 will retain their previously recorded base commit.
210 Some
211 .Nm
212 commands may refuse to run while the work tree contains files from
213 multiple base commits.
214 The base commit of such a work tree can be made consistent by running
215 .Cm got update
216 across the entire work tree.
217 Specifying a
218 .Ar path
219 is incompatible with the
220 .Fl b
221 option.
222 .Pp
223 .Cm got update
224 cannot update paths with staged changes.
225 If changes have been staged with
226 .Cm got stage ,
227 these changes must first be committed with
228 .Cm got commit
229 or unstaged with
230 .Cm got unstage .
231 .Pp
232 The options for
233 .Cm got update
234 are as follows:
235 .Bl -tag -width Ds
236 .It Fl b Ar branch
237 Switch the work tree's branch reference to the specified
238 .Ar branch
239 before updating the work tree.
240 This option requires that all paths in the work tree are updated.
241 .It Fl c Ar commit
242 Update the work tree to the specified
243 .Ar commit .
244 The expected argument is a commit ID SHA1 hash or an existing reference
245 or tag name which will be resolved to a commit ID.
246 An abbreviated hash argument will be expanded to a full SHA1 hash
247 automatically, provided the abbreviation is unique.
248 If this option is not specified, the most recent commit on the work tree's
249 branch will be used.
250 .El
251 .It Cm up
252 Short alias for
253 .Cm update .
254 .It Cm status Op Ar path ...
255 Show the current modification status of files in a work tree,
256 using the following status codes:
257 .Bl -column YXZ description
258 .It M Ta modified file
259 .It A Ta file scheduled for addition in next commit
260 .It D Ta file scheduled for deletion in next commit
261 .It C Ta modified or added file which contains merge conflicts
262 .It ! Ta versioned file was expected on disk but is missing
263 .It \(a~ Ta versioned file is obstructed by a non-regular file
264 .It ? Ta unversioned item not tracked by
265 .Nm
266 .It m Ta modified file modes (executable bit only)
267 .It N Ta non-existent
268 .Ar path
269 specified on the command line
270 .El
271 .Pp
272 If no
273 .Ar path
274 is specified, show modifications in the entire work tree.
275 Otherwise, show modifications at or within the specified paths.
276 .Pp
277 If changes have been staged with
278 .Cm got stage ,
279 staged changes are shown in the second output column, using the following
280 status codes:
281 .Bl -column YXZ description
282 .It M Ta file modification is staged
283 .It A Ta file addition is staged
284 .It D Ta file deletion is staged
285 .El
286 .Pp
287 Changes created on top of staged changes are indicated in the first column:
288 .Bl -column YXZ description
289 .It MM Ta file was modified after earlier changes have been staged
290 .It MA Ta file was modified after having been staged for addition
291 .El
292 .Pp
293 For compatibility with
294 .Xr cvs 1
295 and
296 .Xr git 1 ,
297 .Cm got status
298 reads
299 .Xr glob 7
300 patterns from
301 .Pa .cvsignore
302 and
303 .Pa .gitignore
304 files in each traversed directory and will not display unversioned files
305 which match these patterns.
306 As an extension to
307 .Xr glob 7
308 matching rules,
309 .Cm got status
310 supports consecutive asterisks,
311 .Dq ** ,
312 which will match an arbitrary amount of directories.
313 Unlike
314 .Xr cvs 1 ,
315 .Cm got status
316 only supports a single ignore pattern per line.
317 Unlike
318 .Xr git 1 ,
319 .Cm got status
320 does not support negated ignore patterns prefixed with
321 .Dq \&! ,
322 and gives no special significance to the location of path component separators,
323 .Dq / ,
324 in a pattern.
325 .It Cm st
326 Short alias for
327 .Cm status .
328 .It Cm log Oo Fl b Oc Oo Fl c Ar commit Oc Oo Fl C Ar number Oc Oo Fl l Ar N Oc Oo Fl p Oc Oo Fl s Ar search-pattern Oc Oo Fl r Ar repository-path Oc Op Ar path
329 Display history of a repository.
330 If a
331 .Ar path
332 is specified, show only commits which modified this path.
333 If invoked in a work tree, the
334 .Ar path
335 is interpreted relative to the current working directory,
336 and the work tree's path prefix is implicitly prepended.
337 Otherwise, the path is interpreted relative to the repository root.
338 .Pp
339 The options for
340 .Cm got log
341 are as follows:
342 .Bl -tag -width Ds
343 .It Fl b
344 Display individual commits which were merged into the current branch
345 from other branches.
346 By default,
347 .Cm got log
348 shows the linear history of the current branch only.
349 .It Fl c Ar commit
350 Start traversing history at the specified
351 .Ar commit .
352 The expected argument is a commit ID SHA1 hash or an existing reference
353 or tag name which will be resolved to a commit ID.
354 An abbreviated hash argument will be expanded to a full SHA1 hash
355 automatically, provided the abbreviation is unique.
356 If this option is not specified, default to the work tree's current branch
357 if invoked in a work tree, or to the repository's HEAD reference.
358 .It Fl C Ar number
359 Set the number of context lines shown in diffs with
360 .Fl p .
361 By default, 3 lines of context are shown.
362 .It Fl l Ar N
363 Limit history traversal to a given number of commits.
364 If this option is not specified, a default limit value of zero is used,
365 which is treated as an unbounded limit.
366 The
367 .Ev GOT_LOG_DEFAULT_LIMIT
368 environment variable may be set to change this default value.
369 .It Fl p
370 Display the patch of modifications made in each commit.
371 If a
372 .Ar path
373 is specified, only show the patch of modifications at or within this path.
374 .It Fl s Ar search-pattern
375 If specified, show only commits with a log message matched by the extended
376 regular expression
377 .Ar search-pattern .
378 Regular expression syntax is documented in
379 .Xr re_format 7 .
380 .It Fl r Ar repository-path
381 Use the repository at the specified path.
382 If not specified, assume the repository is located at or above the current
383 working directory.
384 If this directory is a
385 .Nm
386 work tree, use the repository path associated with this work tree.
387 .El
388 .It Cm diff Oo Fl C Ar number Oc Oo Fl r Ar repository-path Oc Oo Fl s Oc Oo Fl w Oc Op Ar object1 Ar object2 | Ar path
389 When invoked within a work tree with less than two arguments, display
390 uncommitted changes in the work tree.
391 If a
392 .Ar path
393 is specified, only show changes within this path.
394 .Pp
395 If two arguments are provided, treat each argument as a reference, a tag
396 name, or an object ID SHA1 hash, and display differences between the
397 corresponding objects.
398 Both objects must be of the same type (blobs, trees, or commits).
399 An abbreviated hash argument will be expanded to a full SHA1 hash
400 automatically, provided the abbreviation is unique.
401 .Pp
402 The options for
403 .Cm got diff
404 are as follows:
405 .Bl -tag -width Ds
406 .It Fl C Ar number
407 Set the number of context lines shown in the diff.
408 By default, 3 lines of context are shown.
409 .It Fl r Ar repository-path
410 Use the repository at the specified path.
411 If not specified, assume the repository is located at or above the current
412 working directory.
413 If this directory is a
414 .Nm
415 work tree, use the repository path associated with this work tree.
416 .It Fl s
417 Show changes staged with
418 .Cm got stage
419 instead of showing local changes.
420 This option is only valid when
421 .Cm got diff
422 is invoked in a work tree.
423 .It Fl w
424 Ignore whitespace-only changes.
425 .El
426 .It Cm di
427 Short alias for
428 .Cm diff .
429 .It Cm blame Oo Fl c Ar commit Oc Oo Fl r Ar repository-path Oc Ar path
430 Display line-by-line history of a file at the specified path.
431 .Pp

434 are as follows:
435 .Bl -tag -width Ds
436 .It Fl c Ar commit
437 Start traversing history at the specified
438 .Ar commit .
439 The expected argument is a commit ID SHA1 hash or an existing reference
440 or tag name which will be resolved to a commit ID.
441 An abbreviated hash argument will be expanded to a full SHA1 hash
442 automatically, provided the abbreviation is unique.
443 .It Fl r Ar repository-path
444 Use the repository at the specified path.
445 If not specified, assume the repository is located at or above the current
446 working directory.
447 If this directory is a
448 .Nm
449 work tree, use the repository path associated with this work tree.
450 .El
451 .It Cm bl
452 Short alias for
453 .Cm blame .
454 .It Cm tree Oo Fl c Ar commit Oc Oo Fl r Ar repository-path Oc Oo Fl i Oc Oo Fl R Oc Op Ar path
455 Display a listing of files and directories at the specified
456 directory path in the repository.
457 Entries shown in this listing may carry one of the following trailing
458 annotations:
459 .Bl -column YXZ description
460 .It @ Ta entry is a symbolic link
461 .It / Ta entry is a directory
462 .It * Ta entry is an executable file
463 .It $ Ta entry is a Git submodule
464 .El
465 .Pp
466 If no
467 .Ar path
468 is specified, list the repository path corresponding to the current
469 directory of the work tree, or the root directory of the repository
470 if there is no work tree.
471 .Pp
472 The options for
473 .Cm got tree
474 are as follows:
475 .Bl -tag -width Ds
476 .It Fl c Ar commit
477 List files and directories as they appear in the specified
478 .Ar commit .
479 The expected argument is a commit ID SHA1 hash or an existing reference
480 or tag name which will be resolved to a commit ID.
481 An abbreviated hash argument will be expanded to a full SHA1 hash
482 automatically, provided the abbreviation is unique.
483 .It Fl r Ar repository-path
484 Use the repository at the specified path.
485 If not specified, assume the repository is located at or above the current
486 working directory.
487 If this directory is a
488 .Nm
489 work tree, use the repository path associated with this work tree.
490 .It Fl i
491 Show object IDs of files (blob objects) and directories (tree objects).
492 .It Fl R
493 Recurse into sub-directories in the repository.
494 .El

497 .Cm tree .
498 .It Cm ref Oo Fl r Ar repository-path Oc Oo Fl l Oc Oo Fl d Ar name Oc Oo Fl s Oc Op Ar name Ar target
499 Manage references in a repository.
500 .Pp
501 If no options are passed, expect two arguments and attempt to create,
502 or update, the reference with the given
503 .Ar name ,
504 and make it point at the given
505 .Ar target .
506 The name must be an absolute reference name, i.e. it must begin with
507 .Dq refs/ .
508 The target may be an object ID SHA1 hash or an existing reference which
509 will be resolved to an object ID.
510 An abbreviated hash argument will be expanded to a full SHA1 hash
511 automatically, provided the abbreviation is unique.
512 .Pp
513 The options for
514 .Cm got ref
515 are as follows:
516 .Bl -tag -width Ds
517 .It Fl r Ar repository-path
518 Use the repository at the specified path.
519 If not specified, assume the repository is located at or above the current
520 working directory.
521 If this directory is a
522 .Nm
523 work tree, use the repository path associated with this work tree.
524 .It Fl l
525 List all existing references in the repository.
526 .It Fl d Ar name
527 Delete the reference with the specified name from the repository.
528 .It Fl s
529 Create a symbolic reference pointing at the specified
530 .Ar target ,
531 which must be an existing reference.
532 Care should be taken not to create loops between references when
533 this option is used.
534 .El
535 .It Cm branch Oo Fl c Ar commit Oc Oo Fl r Ar repository-path Oc Oo Fl l Oc Oo Fl d Ar name Oc Op Ar name
536 Manage branches in a repository.
537 .Pp
538 Branches are managed via references which live in the
539 .Dq refs/heads/
540 reference namespace.
541 The
542 .Cm got branch
543 command operates on references in this namespace only.
544 .Pp
545 If invoked in a work tree without any arguments, print the name of the
546 work tree's current branch.
547 If a
548 .Ar name
549 argument is passed, attempt to create a branch reference with the given name.
550 By default the new branch reference will point at the latest commit on the
551 work tree's current branch if invoked in a work tree, and otherwise to a commit
552 resolved via the repository's HEAD reference.
553 .Pp
554 The options for
555 .Cm got branch
556 are as follows:
557 .Bl -tag -width Ds
558 .It Fl c Ar commit
559 Make a newly created branch reference point at the specified
560 .Ar commit .
561 The expected
562 .Ar commit
563 argument is a commit ID SHA1 hash or an existing reference
564 or tag name which will be resolved to a commit ID.
565 .It Fl r Ar repository-path
566 Use the repository at the specified path.
567 If not specified, assume the repository is located at or above the current
568 working directory.
569 If this directory is a
570 .Nm
571 work tree, use the repository path associated with this work tree.
572 .It Fl l
573 List all existing branches in the repository.
574 If invoked in a work tree, the work tree's current branch is shown
575 with one the following annotations:
576 .Bl -column YXZ description
577 .It * Ta work tree's base commit matches the branch tip
578 .It \(a~ Ta work tree's base commit is out-of-date
579 .El
580 .It Fl d Ar name
581 Delete the branch with the specified name from the repository.
582 Only the branch reference is deleted.
583 Any commit, tree, and blob objects belonging to the branch
584 remain in the repository and may be removed separately with
585 Git's garbage collector.
586 .El
587 .It Cm br
588 Short alias for
589 .Cm branch .
590 .It Cm tag Oo Fl m Ar message Oc Oo Fl r Ar repository-path Oc Oo Fl l Oc Ar name Op Ar commit
591 Manage tags in a repository.
592 .Pp
593 Tags are managed via references which live in the
594 .Dq refs/tags/
595 reference namespace.
596 The
597 .Cm got tag
598 command operates on references in this namespace only.
599 References in this namespace point at tag objects which contain a pointer
600 to another object, a tag message, as well as author and timestamp information.
601 .Pp
602 Expect one or two arguments and attempt to create a tag with the given
603 .Ar name ,
604 and make this tag point at the given
605 .Ar commit .
606 If no commit is specified, default to the latest commit on the work tree's
607 current branch if invoked in a work tree, and to a commit resolved via
608 the repository's HEAD reference otherwise.
609 Otherwise, the expected argument is a commit ID SHA1 hash or an existing
610 reference or tag name which will be resolved to a commit ID.
611 An abbreviated hash argument will be expanded to a full SHA1 hash
612 automatically, provided the abbreviation is unique.
613 .Pp
614 The options for
615 .Cm got tag
616 are as follows:
617 .Bl -tag -width Ds
618 .It Fl m Ar message
619 Use the specified tag message when creating the new tag
620 Without the
621 .Fl m
622 option,
623 .Cm got tag
624 opens a temporary file in an editor where a tag message can be written.
625 .It Fl r Ar repository-path
626 Use the repository at the specified path.

1414 Alternatively, for quick and dirty local testing of

1416 a new Git repository could be created and populated with files,
1417 e.g. from a temporary CVS checkout located at

1420 .Dl $ got init /var/git/src.git
1421 .Dl $ got import -r /var/git/src.git -I CVS -I obj /tmp/src
1422 .Pp

1424 .Pp
1425 .Dl $ got checkout /var/git/src.git /usr/src
1426 .Pp
1427 View local changes in a work tree directory:
1428 .Pp
1429 .Dl $ got status
1430 .Dl $ got diff | less
1431 .Pp
1432 Interactively revert selected local changes in a work tree directory:
1433 .Pp
1434 .Dl $ got revert -p -R\ .
1435 .Pp
1436 In a work tree or a git repository directory, list all branch references:
1437 .Pp
1438 .Dl $ got branch -l
1439 .Pp
1440 In a work tree or a git repository directory, create a new branch called
1441 .Dq unified-buffer-cache
1442 which is forked off the
1443 .Dq master
1444 branch:
1445 .Pp
1446 .Dl $ got branch unified-buffer-cache master
1447 .Pp
1448 Switch an existing work tree to the branch
1449 .Dq unified-buffer-cache .
1450 Local changes in the work tree will be preserved and merged if necessary:
1451 .Pp
1452 .Dl $ got update -b unified-buffer-cache
1453 .Pp
1454 Create a new commit from local changes in a work tree directory.
1455 This new commit will become the head commit of the work tree's current branch:
1456 .Pp
1457 .Dl $ got commit
1458 .Pp
1459 In a work tree or a git repository directory, view changes committed in
1460 the 3 most recent commits to the work tree's branch, or the branch resolved
1461 via the repository's HEAD reference, respectively:
1462 .Pp
1463 .Dl $ got log -p -l 3
1464 .Pp
1465 In a work tree or a git repository directory, log the history of a subdirectory:
1466 .Pp
1467 .Dl $ got log sys/uvm
1468 .Pp
1469 While operating inside a work tree, paths are specified relative to the current
1470 working directory, so this command will log the subdirectory
1471 .Pa sys/uvm :
1472 .Pp
1473 .Dl $ cd sys/uvm && got log '.'
1474 .Pp
1475 And this command has the same effect:
1476 .Pp
1477 .Dl $ cd sys/dev/usb && got log ../../uvm
1478 .Pp
1479 Add new files and remove obsolete files in a work tree directory:

1481 .Dl $ got add sys/uvm/uvm_ubc.c
1482 .Dl $ got remove sys/uvm/uvm_vnode.c
1483 .Pp
1484 Create a new commit from local changes in a work tree directory
1485 with a pre-defined log message.
1486 .Pp
1487 .Dl $ got commit -m 'unify the buffer cache'
1488 .Pp
1489 Update any work tree checked out from the
1490 .Dq unified-buffer-cache
1491 branch to the latest commit on this branch:
1492 .Pp
1493 .Dl $ got update
1494 .Pp
1495 Roll file content on the unified-buffer-cache branch back by one commit,
1496 and then fetch the rolled-back change into the work tree as a local change
1497 to be amended and perhaps committed again:
1498 .Pp
1499 .Dl $ got backout unified-buffer-cache
1500 .Dl $ got commit -m 'roll back previous'
1501 .Dl $ # now back out the previous backout :-)
1502 .Dl $ got backout unified-buffer-cache
1503 .Pp
1504 Fetch new upstream commits into the local repository's master branch.
1505 This step currently requires

1507 .Pp
1508 .Dl $ cd /var/git/src.git
1509 .Dl $ git fetch origin master:master
1510 .Pp
1511 Rebase the

1513 branch on top of the new head commit of the
1514 .Dq master
1515 branch.
1516 .Pp
1517 .Dl $ got update -b master
1518 .Dl $ got rebase unified-buffer-cache
1519 .Pp
1520 Create a patch from all changes on the unified-buffer-cache branch.
1521 The patch can be mailed out for review and applied to
1522 .Ox Ns 's
1523 CVS tree:
1524 .Pp
1525 .Dl $ got diff master unified-buffer-cache > /tmp/ubc.diff
1526 .Pp

1532 .Dl $ got update -c master
1533 .Dl $ got histedit
1534 .Pp
1535 Additional steps are necessary if local changes need to be pushed back
1536 to the remote repository, which currently requires
1537 .Cm git fetch
1538 and
1539 .Cm git push .
1540 Before working against existing branches in a repository cloned with
1541 .Dq git clone --bare ,
1542 a Git
1543 .Dq refspec
1544 must be configured to map all references in the remote repository
1545 into the
1546 .Dq refs/remotes
1547 namespace of the local repository.
1548 This can achieved by setting Git's
1549 .Pa remote.origin.fetch
1550 configuration variable to the value
1551 .Dq +refs/heads/*:refs/remotes/origin/*
1552 with the
1553 .Cm git config
1554 command:
1555 .Pp
1556 .Dl $ cd /var/git/repo
1557 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
1558 .Pp
1559 Alternatively, the following
1560 .Pa fetch
1561 configuration item can be added manually to the Git repository's
1562 .Pa config
1563 file:
1564 .Pp
1565 .Dl [remote "origin"]
1566 .Dl url = ...
1567 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
1568 .Pp
1569 This configuration leaves the local repository's
1570 .Dq refs/heads
1571 namespace free for use by local branches checked out with
1572 .Cm got checkout
1573 and, if needed, created with
1574 .Cm got branch .
1575 .Pp
1576 Branches in the
1577 .Dq remotes/origin
1578 namespace can be updated with incoming changes from the remote
1579 repository with
1580 .Cm git fetch :
1581 .Pp
1582 .Dl $ cd /var/git/repo
1583 .Dl $ git fetch
1584 .Pp
1585 To make changes fetched from the remote repository appear on the
1586 .Dq master
1587 branch, the
1588 .Dq master
1589 branch must be rebased onto the
1590 .Dq origin/master
1591 branch.
1592 This will also merge local changes, if any, with the incoming changes:
1593 .Pp
1594 .Dl $ got update -b origin/master
1595 .Dl $ got rebase master
1596 .Pp
1597 On the
1598 .Dq master
1599 branch, log messages for local changes can now be amended with
1600 .Dq OK
1601 by other developers and any other important new information:
1602 .Pp
1603 .Dl $ got update -c origin/master
1604 .Dl $ got histedit -m
1605 .Pp
1606 Local changes on the
1607 .Dq master
1608 branch can then be pushed to the remote
1609 repository with
1610 .Cm git push :
1611 .Pp
1612 .Dl $ cd /var/git/repo
1613 .Dl $ git push origin master
1614 .Pp
1615 In order to merge changes committed to the
1616 .Dq unified-buffer-cache
1617 branch back into the
1618 .Dq master
1619 branch, the
1620 .Dq unified-buffer-cache
1621 branch must first be rebased onto the
1622 .Dq master
1623 branch:
1624 .Pp
1625 .Dl $ got update -b master
1626 .Dl $ got rebase unified-buffer-cache
1627 .Pp
1628 Changes on the
1629 .Dq unified-buffer-cache
1630 branch can now be made visible on the
1631 .Dq master
1632 branch with
1633 .Cm got integrate .
1634 Because the rebase operation switched the work tree to the
1635 .Dq unified-buffer-cache
1636 branch, the work tree must be switched back to the
1637 .Dq master
1638 branch before the
1639 .Dq unified-buffer-cache
1640 branch can be integrated into
1641 .Dq master :
1642 .Pp
1643 .Dl $ got update -b master
1644 .Dl $ got integrate unified-buffer-cache
