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 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
77 Create an initial commit in a repository from the file hierarchy
78 within the specified
79 .Ar directory .
80 The created commit will not have any parent commits, i.e. it will be a
81 root commit.
82 Also create a new reference which provides a branch name for the newly
83 created commit.
84 Show the path of each imported file to indicate progress.
85 .Pp
86 The
87 .Cm got import
88 command requires the
89 .Ev GOT_AUTHOR
90 environment variable to be set,
91 unless an author has been configured in
92 .Xr got.conf 5
93 or Git's
94 .Dv user.name
95 and
96 .Dv user.email
97 configuration settings can be obtained from the repository's
98 .Pa .git/config
99 file or from Git's global
100 .Pa ~/.gitconfig
101 configuration file.
102 .Pp
103 The options for
104 .Cm got import
105 are as follows:
106 .Bl -tag -width Ds
107 .It Fl b Ar branch
108 Create the specified
109 .Ar branch
110 instead of creating the default branch
111 .Dq main .
112 Use of this option is required if the
113 .Dq main
114 branch already exists.
115 .It Fl m Ar message
116 Use the specified log message when creating the new commit.
117 Without the
118 .Fl m
119 option,
120 .Cm got import
121 opens a temporary file in an editor where a log message can be written.
122 .It Fl r Ar repository-path
123 Use the repository at the specified path.
124 If not specified, assume the repository is located at or above the current
125 working directory.
126 .It Fl I Ar pattern
127 Ignore files or directories with a name which matches the specified
128 .Ar pattern .
129 This option may be specified multiple times to build a list of ignore patterns.
130 The
131 .Ar pattern
132 follows the globbing rules documented in
133 .Xr glob 7 .
134 .El
135 .It Cm im
136 Short alias for
137 .Cm import .
138 .It Cm clone Oo Fl a Oc Oo Fl b Ar branch Oc Oo Fl l Oc Oo Fl m Oc Oo Fl q Oc Oo Fl v Oc Oo Fl R Ar reference Oc Ar repository-URL Op Ar directory
139 Clone a Git repository at the specified
140 .Ar repository-URL
141 into the specified
142 .Ar directory .
143 If no
144 .Ar directory
145 is specified the directory name will be derived from the name of the
146 cloned repository.
147 .Cm got clone
148 will refuse to run if the
149 .Ar directory
150 already exists.
151 .Pp
152 The
153 .Ar repository-URL
154 specifies a protocol scheme, a server hostname, an optional port number
155 separated from the hostname by a colon, and a path to the repository on
156 the server:
157 .Lk scheme://hostname:port/path/to/repository
158 .Pp
159 The following protocol schemes are supported:
160 .Bl -tag -width git+ssh
161 .It git
162 The Git protocol as implemented by the
163 .Xr git-daemon 1
164 server.
165 Use of this protocol is discouraged since it supports neither authentication
166 nor encryption.
167 .It git+ssh
168 The Git protocol wrapped in an authenticated and encrypted
169 .Xr ssh 1
170 tunnel.
171 With this protocol the hostname may contain an embedded username for
172 .Xr ssh 1
173 to use:
174 .Mt user@hostname
175 .It ssh
176 Short alias for git+ssh.
177 .El
178 .Pp
179 Objects in the cloned repository are stored in a pack file which is downloaded
180 from the server.
181 This pack file will then be indexed to facilitate access to the objects stored
182 within.
183 If any objects in the pack file are stored in deltified form, all deltas will
184 be fully resolved in order to compute the ID of such objects.
185 This can take some time.
186 More details about the pack file format are documented in
187 .Xr git-repository 5 .
188 .Pp
189 .Cm got clone
190 creates a remote repository entry in the
191 .Xr got.conf 5
192 and
193 .Pa config
194 files of the cloned repository to store the
195 .Ar repository-url
196 and any
197 .Ar branch
198 or
199 .Ar reference
200 arguments for future use by
201 .Cm got fetch
202 or
203 .Xr git-fetch 1 .
204 .Pp
205 The options for
206 .Cm got clone
207 are as follows:
208 .Bl -tag -width Ds
209 .It Fl a
210 Fetch all branches from the remote repository's
211 .Dq refs/heads/
212 reference namespace and set
213 .Cm fetch-all-branches
214 in the cloned repository's
215 .Xr got.conf 5
216 file for future use by
217 .Cm got fetch .
218 If this option is not specified, a branch resolved via the remote
219 repository's HEAD reference will be fetched.
220 Cannot be used together with the
221 .Fl b
222 option.
223 .It Fl b Ar branch
224 Fetch the specified
225 .Ar branch
226 from the remote repository's
227 .Dq refs/heads/
228 reference namespace.
229 This option may be specified multiple times to build a list of branches
230 to fetch.
231 If the branch corresponding to the remote repository's HEAD reference is not
232 in this list, the cloned repository's HEAD reference will be set to the first
233 branch which was fetched.
234 If this option is not specified, a branch resolved via the remote
235 repository's HEAD reference will be fetched.
236 Cannot be used together with the
237 .Fl a
238 option.
239 .It Fl l
240 List branches and tags available for fetching from the remote repository
241 and exit immediately.
242 Cannot be used together with any of the other options except
243 .Fl q
244 and
245 .Fl v .
246 .It Fl m
247 Create the cloned repository as a mirror of the original repository.
248 This is useful if the cloned repository will not be used to store
249 locally created commits.
250 .Pp
251 The repository's
252 .Xr got.conf 5
253 and
254 .Pa config
255 files will be set up with the
256 .Dq mirror
257 option enabled, such that
258 .Cm got fetch
259 or
260 .Xr git-fetch 1
261 will write incoming changes directly to branches in the
262 .Dq refs/heads/
263 reference namespace, rather than to branches in the
264 .Dq refs/remotes/
265 namespace.
266 This avoids the usual requirement of having to run
267 .Cm got rebase
268 after
269 .Cm got fetch
270 in order to make incoming changes appear on branches in the
271 .Dq refs/heads/
272 namespace.
273 But maintaining custom changes in the cloned repository becomes difficult
274 since such changes will be at risk of being discarded whenever incoming
275 changes are fetched.
276 .It Fl q
277 Suppress progress reporting output.
278 The same option will be passed to
279 .Xr ssh 1
280 if applicable.
281 .It Fl v
282 Verbose mode.
283 Causes
284 .Cm got clone
285 to print debugging messages to standard error output.
286 This option will be passed to
287 .Xr ssh 1
288 if applicable.
289 Multiple -v options increase the verbosity.
290 The maximum is 3.
291 .It Fl R Ar reference
292 In addition to the branches and tags that will be fetched, fetch an arbitrary
293 .Ar reference
294 from the remote repository's
295 .Dq refs/
296 namespace.
297 This option may be specified multiple times to build a list of additional
298 references to fetch.
299 The specified
300 .Ar reference
301 may either be a path to a specific reference, or a reference namespace
302 which will cause all references in this namespace to be fetched.
303 .Pp
304 Each reference will be mapped into the cloned repository's
305 .Dq refs/remotes/
306 namespace, unless the
307 .Fl m
308 option is used to mirror references directly into the cloned repository's
309 .Dq refs/
310 namespace.
311 .Pp
312 .Cm got clone
313 will refuse to fetch references from the remote repository's
314 .Dq refs/remotes/
315 or
316 .Dq refs/got/
317 namespace.
318 .El
319 .It Cm cl
320 Short alias for
321 .Cm clone .
322 .It Cm fetch Oo Fl a Oc Oo Fl b Ar branch Oc Oo Fl d Oc Oo Fl l Oc Oo Fl r Ar repository-path Oc Oo Fl t Oc Oo Fl q Oc Oo Fl v Oc Oo Fl R Ar reference Oc Op Ar remote-repository
323 Fetch new changes from a remote repository.
324 If no
325 .Ar remote-repository
326 is specified,
327 .Dq origin
328 will be used.
329 The remote repository's URL is obtained from the corresponding entry in
330 .Xr got.conf 5
331 or Git's
332 .Pa config
333 file of the local repository, as created by
334 .Cm got clone .
335 .Pp
336 New changes will be stored in a separate pack file downloaded from the server.
337 Optionally, separate pack files stored in the repository can be combined with
338 .Xr git-repack 1 .
339 .Pp
340 By default, branch references in the
341 .Dq refs/remotes/
342 reference namespace will be updated to point at the newly fetched commits.
343 The
344 .Cm got rebase
345 command can then be used to make new changes visible on branches in the
346 .Dq refs/heads/
347 namespace, merging incoming changes with the changes on those branches
348 as necessary.
349 .Pp
350 If the repository was created as a mirror with
351 .Cm got clone -m
352 then all branches in the
353 .Dq refs/heads/
354 namespace will be updated directly to match the corresponding branches in
355 the remote repository.
356 If those branches contained local commits, these commits will no longer be
357 reachable via a reference and will therefore be at risk of being discarded
358 by Git's garbage collector.
359 Maintaining custom changes in a mirror repository is therefore discouraged.
360 .Pp
361 In any case, references in the
362 .Dq refs/tags/
363 namespace will always be fetched and mapped directly to local references
364 in the same namespace.
365 .Pp
366 The options for
367 .Cm got fetch
368 are as follows:
369 .Bl -tag -width Ds
370 .It Fl a
371 Fetch all branches from the remote repository's
372 .Dq refs/heads/
373 reference namespace.
374 This option can be enabled by default for specific repositories in
375 .Xr got.conf 5 .
376 If this option is not specified, a branch resolved via the remote
377 repository's HEAD reference will be fetched.
378 Cannot be used together with the
379 .Fl b
380 option.
381 .It Fl b Ar branch
382 Fetch the specified
383 .Ar branch
384 from the remote repository's
385 .Dq refs/heads/
386 reference namespace.
387 This option may be specified multiple times to build a list of branches
388 to fetch.
389 If this option is not specified, a branch resolved via the remote
390 repository's HEAD reference will be fetched.
391 Cannot be used together with the
392 .Fl a
393 option.
394 .It Fl d
395 Delete branches and tags from the local repository which are no longer
396 present in the remote repository.
397 Only references are deleted.
398 Any commit, tree, tag, and blob objects belonging to deleted branches or
399 tags remain in the repository and may be removed separately with
400 Git's garbage collector.
401 .It Fl l
402 List branches and tags available for fetching from the remote repository
403 and exit immediately.
404 Cannot be used together with any of the other options except
405 .Fl v ,
406 .Fl q ,
407 and
408 .Fl r .
409 .It Fl t
410 Allow existing references in the
411 .Dq refs/tags
412 namespace to be updated if they have changed on the server.
413 If not specified, only new tag references will be created.
414 .It Fl r Ar repository-path
415 Use the repository at the specified path.
416 If not specified, assume the repository is located at or above the current
417 working directory.
418 If this directory is a
419 .Nm
420 work tree, use the repository path associated with this work tree.
421 .It Fl q
422 Suppress progress reporting output.
423 The same option will be passed to
424 .Xr ssh 1
425 if applicable.
426 .It Fl v
427 Verbose mode.
428 Causes
429 .Cm got fetch
430 to print debugging messages to standard error output.
431 The same option will be passed to
432 .Xr ssh 1
433 if applicable.
434 Multiple -v options increase the verbosity.
435 The maximum is 3.
436 .It Fl R Ar reference
437 In addition to the branches and tags that will be fetched, fetch an arbitrary
438 .Ar reference
439 from the remote repository's
440 .Dq refs/
441 namespace.
442 This option may be specified multiple times to build a list of additional
443 references to fetch.
444 The specified
445 .Ar reference
446 may either be a path to a specific reference, or a reference namespace
447 which will cause all references in this namespace to be fetched.
448 .Pp
449 Each reference will be mapped into the local repository's
450 .Dq refs/remotes/
451 namespace, unless the local repository was created as a mirror with
452 .Cm got clone -m
453 in which case references will be mapped directly into the local repository's
454 .Dq refs/
455 namespace.
456 .Pp
457 Once a reference has been fetched, a branch based on it can be created with
458 .Cm got branch
459 if needed.
460 .Pp
461 .Cm got fetch
462 will refuse to fetch references from the remote repository's
463 .Dq refs/remotes/
464 or
465 .Dq refs/got/
466 namespace.
467 .El
468 .It Cm fe
469 Short alias for
470 .Cm fetch .
471 .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
472 Copy files from a repository into a new work tree.
473 Show the status of each affected file, using the following status codes:
474 .Bl -column YXZ description
475 .It A Ta new file was added
476 .It E Ta file already exists in work tree's meta-data
477 .El
478 .Pp
479 If the
480 .Ar work tree path
481 is not specified, either use the last component of
482 .Ar repository path ,
483 or if a
484 .Ar path prefix
485 was specified use the last component of
486 .Ar path prefix .
487 .Pp
488 The options for
489 .Cm got checkout
490 are as follows:
491 .Bl -tag -width Ds
492 .It Fl E
493 Proceed with the checkout operation even if the directory at
494 .Ar work-tree-path
495 is not empty.
496 Existing files will be left intact.
497 .It Fl b Ar branch
498 Check out files from a commit on the specified
499 .Ar branch .
500 If this option is not specified, a branch resolved via the repository's HEAD
501 reference will be used.
502 .It Fl c Ar commit
503 Check out files from the specified
504 .Ar commit
505 on the selected branch.
506 The expected argument is a commit ID SHA1 hash or an existing reference
507 or tag name which will be resolved to a commit ID.
508 An abbreviated hash argument will be expanded to a full SHA1 hash
509 automatically, provided the abbreviation is unique.
510 If this option is not specified, the most recent commit on the selected
511 branch will be used.
512 .Pp
513 If the specified
514 .Ar commit
515 is not contained in the selected branch, a different branch which contains
516 this commit must be specified with the
517 .Fl b
518 option.
519 If no such branch is known a new branch must be created for this
520 commit with
521 .Cm got branch
522 before
523 .Cm got checkout
524 can be used.
525 Checking out work trees with an unknown branch is intentionally not supported.
526 .It Fl p Ar path-prefix
527 Restrict the work tree to a subset of the repository's tree hierarchy.
528 Only files beneath the specified
529 .Ar path-prefix
530 will be checked out.
531 .El
532 .It Cm co
533 Short alias for
534 .Cm checkout .
535 .It Cm update Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Op Ar path ...
536 Update an existing work tree to a different
537 .Ar commit .
538 Change existing files in the work tree as necessary to match file contents
539 of this commit.
540 Preserve any local changes in the work tree and merge them with the
541 incoming changes.
542 .Pp
543 Files which already contain merge conflicts will not be updated to avoid
544 further complications.
545 Such files will be updated when
546 .Cm got update
547 is run again after merge conflicts have been resolved.
548 If the conflicting changes are no longer needed affected files can be
549 reverted with
550 .Cm got revert
551 before running
552 .Cm got update
553 again.
554 .Pp
555 Show the status of each affected file, using the following status codes:
556 .Bl -column YXZ description

564 .It # Ta file was not updated because it contains merge conflicts
565 .It ? Ta changes destined for an unversioned file were not merged
566 .El
567 .Pp
568 If no
569 .Ar path
570 is specified, update the entire work tree.
571 Otherwise, restrict the update operation to files at or within the
572 specified paths.
573 Each path is required to exist in the update operation's target commit.
574 Files in the work tree outside specified paths will remain unchanged and
575 will retain their previously recorded base commit.
576 Some
577 .Nm
578 commands may refuse to run while the work tree contains files from
579 multiple base commits.
580 The base commit of such a work tree can be made consistent by running
581 .Cm got update
582 across the entire work tree.
583 Specifying a
584 .Ar path
585 is incompatible with the
586 .Fl b
587 option.
588 .Pp
589 .Cm got update
590 cannot update paths with staged changes.
591 If changes have been staged with
592 .Cm got stage ,
593 these changes must first be committed with
594 .Cm got commit
595 or unstaged with
596 .Cm got unstage .
597 .Pp
598 The options for
599 .Cm got update
600 are as follows:
601 .Bl -tag -width Ds
602 .It Fl b Ar branch
603 Switch the work tree's branch reference to the specified
604 .Ar branch
605 before updating the work tree.
606 This option requires that all paths in the work tree are updated.
607 .Pp
608 As usual, any local changes in the work tree will be preserved.
609 This can be useful when switching to a newly created branch in order
610 to commit existing local changes to this branch.
611 .Pp
612 Any local changes must be dealt with separately in order to obtain a
613 work tree with pristine file contents corresponding exactly to the specified
614 .Ar branch .
615 Such changes could first be committed to a different branch with
616 .Cm got commit ,
617 or could be discarded with
618 .Cm got revert .
619 .It Fl c Ar commit
620 Update the work tree to the specified
621 .Ar commit .
622 The expected argument is a commit ID SHA1 hash or an existing reference
623 or tag name which will be resolved to a commit ID.
624 An abbreviated hash argument will be expanded to a full SHA1 hash
625 automatically, provided the abbreviation is unique.
626 If this option is not specified, the most recent commit on the work tree's
627 branch will be used.

685 For compatibility with
686 .Xr cvs 1
687 and
688 .Xr git 1 ,
689 .Cm got status
690 reads
691 .Xr glob 7
692 patterns from
693 .Pa .cvsignore
694 and
695 .Pa .gitignore
696 files in each traversed directory and will not display unversioned files
697 which match these patterns.
698 As an extension to
699 .Xr glob 7
700 matching rules,
701 .Cm got status
702 supports consecutive asterisks,
703 .Dq ** ,
704 which will match an arbitrary amount of directories.
705 Unlike
706 .Xr cvs 1 ,
707 .Cm got status
708 only supports a single ignore pattern per line.
709 Unlike
710 .Xr git 1 ,
711 .Cm got status
712 does not support negated ignore patterns prefixed with
713 .Dq \&! ,
714 and gives no special significance to the location of path component separators,
715 .Dq / ,
716 in a pattern.

1055 Tags are managed via references which live in the
1056 .Dq refs/tags/
1057 reference namespace.
1058 The
1059 .Cm got tag
1060 command operates on references in this namespace only.
1061 References in this namespace point at tag objects which contain a pointer
1062 to another object, a tag message, as well as author and timestamp information.
1063 .Pp
1064 Attempt to create a tag with the given

1273 Use the specified log message when creating the new commit.
1274 Without the
1275 .Fl m
1276 option,
1277 .Cm got commit
1278 opens a temporary file in an editor where a log message can be written.
1279 .It Fl S
1280 Allow the addition of symbolic links which point outside of the path space
1281 that is under version control.
1282 By default,
1283 .Cm got commit
1284 will reject such symbolic links due to safety concerns.
1285 As a precaution,
1286 .Nm
1287 may decide to represent such a symbolic link as a regular file which contains
1288 the link's target path, rather than creating an actual symbolic link which
1289 points outside of the work tree.
1290 Use of this option is discouraged because external mechanisms such as
1291 .Dq make obj
1292 are better suited for managing symbolic links to paths not under
1293 version control.

1402 The
1403 .Ar branch
1404 must share common ancestry with the work tree's current branch.
1405 Rebasing begins with the first descendant commit of the youngest
1406 common ancestor commit shared by the specified
1407 .Ar branch
1408 and the work tree's current branch, and stops once the tip commit
1409 of the specified
1410 .Ar branch
1411 has been rebased.
1412 .Pp
1413 When
1414 .Cm got rebase
1415 is used as intended, the specified
1416 .Ar branch
1417 represents a local commit history and may already contain changes
1418 that are not yet visible in any other repositories.
1419 The work tree's current branch, which must be set with
1420 .Cm got update -b
1421 before starting the
1422 .Cm rebase
1423 operation, represents a branch from a remote repository which shares
1424 a common history with the specified
1425 .Ar branch
1426 but has progressed, and perhaps diverged, due to commits added to the
1427 remote repository.
1428 .Pp
1429 Rebased commits are accumulated on a temporary branch which the work tree
1430 will remain switched to throughout the entire rebase operation.
1431 Commits on this branch represent the same changes with the same log
1432 messages as their counterparts on the original
1433 .Ar branch ,
1434 but with different commit IDs.
1435 Once rebasing has completed successfully, the temporary branch becomes
1436 the new version of the specified
1437 .Ar branch
1438 and the work tree is automatically switched to it.
1439 .Pp
1440 While rebasing commits, show the status of each affected file,

1453 If merge conflicts occur the rebase operation is interrupted and may
1454 be continued once conflicts have been resolved.
1455 Alternatively, the rebase operation may be aborted which will leave
1456 .Ar branch
1457 unmodified and the work tree switched back to its original branch.
1458 .Pp
1459 If a merge conflict is resolved in a way which renders the merged
1460 change into a no-op change, the corresponding commit will be elided
1461 when the rebase operation continues.

1512 operation the work tree's current branch must be set with
1513 .Cm got update -b
1514 to the branch which should be edited, unless this branch is already the
1515 current branch of the work tree.
1516 The tip of this branch represents the upper bound (inclusive) of commits
1517 touched by the
1518 .Cm histedit
1519 operation.
1520 .Pp
1521 Furthermore, the work tree's base commit
1522 must be set with
1523 .Cm got update -c
1524 to a point in this branch's commit history where editing should begin.
1525 This commit represents the lower bound (non-inclusive) of commits touched
1526 by the

1534 .Fl f
1536 .Fl m
1537 options.
1538 .Pp
1539 The format of the histedit script is line-based.
1540 Each line in the script begins with a command name, followed by
1541 whitespace and an argument.
1542 For most commands, the expected argument is a commit ID SHA1 hash.
1543 Any remaining text on the line is ignored.
1544 Lines which begin with the

1559 log message can be written.
1560 .El
1561 .Pp
1562 Every commit in the history being edited must be mentioned in the script.
1563 Lines may be re-ordered to change the order of commits in the edited history.
1564 No commit may be listed more than once.
1565 .Pp
1566 Edited commits are accumulated on a temporary branch which the work tree
1567 will remain switched to throughout the entire histedit operation.
1568 Once history editing has completed successfully, the temporary branch becomes
1569 the new version of the work tree's branch and the work tree is automatically
1570 switched to it.

2078 .Pp
2079 .Dl $ got update -b unified-buffer-cache

2186 .Pp
2187 .Dl $ got update -b master
2188 .Dl $ got rebase unified-buffer-cache
2189 .Pp
2190 Create a patch from all changes on the unified-buffer-cache branch.
2191 The patch can be mailed out for review and applied to

2205 In order to merge changes committed to the

2209 branch, the
2210 .Dq unified-buffer-cache

2214 .Pp
2215 .Dl $ got update -b master
2216 .Dl $ got rebase unified-buffer-cache

2220 branch can now be made visible on the
2221 .Dq master
2222 branch with
2223 .Cm got integrate .
2224 Because the rebase operation switched the work tree to the
2225 .Dq unified-buffer-cache
2226 branch, the work tree must be switched back to the
2227 .Dq master
2228 branch before the
2229 .Dq unified-buffer-cache
2230 branch can be integrated into
2231 .Dq master :
2232 .Pp
2233 .Dl $ got update -b master
2234 .Dl $ got integrate unified-buffer-cache
2235 .Pp
2236 Additional steps may be necessary if local changes need to be pushed back
2237 to the remote repository, which currently requires
2238 .Cm git push .
2239 Before working against existing branches in a repository cloned with
2240 .Cm git clone --bare
2241 instead of
2242 .Cm got clone ,
2243 a Git
2244 .Dq refspec
2245 must be configured to map all references in the remote repository
2246 into the
2247 .Dq refs/remotes
2248 namespace of the local repository.
2249 This can achieved by setting Git's
2250 .Pa remote.origin.fetch
2251 configuration variable to the value
2252 .Dq +refs/heads/*:refs/remotes/origin/*
2253 with the
2254 .Cm git config
2255 command:
2256 .Pp
2257 .Dl $ cd /var/git/repo
2258 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
2259 .Pp
2260 Additionally, the
2261 .Dq mirror
2262 option must be disabled:
2263 .Pp
2264 .Dl $ cd /var/git/repo
2265 .Dl $ git config remote.origin.mirror false
2266 .Pp
2267 Alternatively, the following
2268 .Xr git-fetch 1
2269 configuration item can be added manually to the Git repository's
2270 .Pa config
2271 file:
2272 .Pp
2273 .Dl [remote "origin"]
2274 .Dl url = ...
2275 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
2276 .Dl mirror = false
2277 .Pp
2278 This configuration leaves the local repository's
2279 .Dq refs/heads
2280 namespace free for use by local branches checked out with
2281 .Cm got checkout
2282 and, if needed, created with
2283 .Cm got branch .
2284 .Pp
2285 Branches in the
2286 .Dq remotes/origin
2287 namespace can now be updated with incoming changes from the remote
2288 repository with
2289 .Cm got fetch
2291 .Xr git-fetch 1
2292 without extra command line arguments:
2293 .Pp
2294 .Dl $ cd /var/git/repo
2295 .Dl $ git fetch
2296 .Pp
2297 To make changes fetched from the remote repository appear on the
2298 .Dq master
2299 branch, the
2300 .Dq master
2301 branch must be rebased onto the
2302 .Dq origin/master
2303 branch.
2304 This will also merge local changes, if any, with the incoming changes:
2305 .Pp
2306 .Dl $ got update -b origin/master
2307 .Dl $ got rebase master
2308 .Pp
2309 On the
2310 .Dq master
2311 branch, log messages for local changes can now be amended with
2312 .Dq OK
2313 by other developers and any other important new information:
2314 .Pp
2315 .Dl $ got update -c origin/master
2316 .Dl $ got histedit -m
2317 .Pp
2318 Local changes on the
2319 .Dq master
2320 branch can then be pushed to the remote
2321 repository with
2322 .Cm git push :
