21 .Nd Game of Trees repository administration
29 is the repository maintenance tool for the
31 version control system.
34 stores the history of tracked files in a Git repository, as used
35 by the Git version control system.
37 provides commands for inspecting and manipulating the on-disk state of
39 The repository format is described in
40 .Xr git-repository 5 .
43 provides global and command-specific options.
44 Global options must precede the command name, and are as follows:
45 .Bl -tag -width tenletters
47 Display usage information and exit immediately.
49 Display program version and exit immediately.
55 .Bl -tag -width checkout
56 .It Cm init Oo Fl b Ar branch Oc Ar repository-path

78 .It Cm info Op Fl r Ar repository-path

80 This includes some configuration settings from
82 and the number of objects stored in the repository, in packed or
83 loose form, as well as the current on-disk size of these objects.
89 .It Fl r Ar repository-path

95 work tree, use the repository path associated with this work tree.

105 By default, add any loose objects which are reachable via any references
106 to the generated pack file.
110 arguments is specified, only add objects which are reachable via the specified
114 argument may either specify a specific reference or a reference namespace,
115 in which case all references within this namespace will be used.
118 always ignores references in the
120 namespace, effectively treating such references as if they did not refer
128 Add objects to the generated pack file even if they are already packed
129 in a different pack file.
130 Unless this option is specified, only loose objects will be added.
132 Force the use of ref-delta representation for deltified objects.
133 If this option is not specified, offset-deltas will be used to represent
136 Suppress progress reporting output.

150 argument may either specify a specific reference or a reference namespace,
151 in which case all references within this namespace will be excluded.
154 option may be specified multiple times to build a list of references to exclude.
156 Exclusion takes precedence over inclusion.
157 If a reference appears in both the included and excluded lists, it will
161 .It Cm indexpack Ar packfile-path
163 Create a pack index for the pack file at
166 A pack index is required for using the corresponding pack file with
168 Usually, a pack index will be created by commands such as
172 as part of regular operation.
174 .Cm gotadmin indexpack
175 command may be used to recover from a corrupt or missing index.
176 A given pack file will always yield the same bit-identical index.
180 must be located within the
182 directory of the repository and should end in
184 The filename of the corresponding pack index is equivalent, except
194 List the contents of the pack file at
197 Each object contained in the pack file will be displayed on a single line.
198 The information shown includes the object ID, object type, object offset,
201 If a packed object is deltified against another object, the delta base
202 will be shown as well.
203 For offset deltas, the delta base is identified via an offset into the
205 For reference deltas, the delta base is identified via an object ID.
209 must be located within the
211 directory of the repository and should end in
213 The corresponding pack index must exist and can be created with
214 .Cm gotadmin indexpack
218 .Cm gotadmin listpack
222 Show object sizes in human-readable form.
224 Display statistics about the pack file after listing objects.
225 This includes the total number of objects stored in the pack file
226 and a break-down of the number of objects per object type.
232 .Op Fl r Ar repository-path
235 Purge unreferenced loose objects from the repository and display
236 the amount of disk space which has been freed as a result.
238 Unreferenced objects are present in the repository but cannot be
239 reached via any reference in the entire
243 Loose objects are stored as individual files beneath the repository's
246 spread across 256 sub-directories named after the 256 possible
247 hexadecimal values of the first byte of an object identifier.
249 Packed objects stored in pack files under
252 However, if redundant copies of packed objects exist in loose form,
253 such redundant copies will be purged.
255 Objects will usually become unreferenced as a result of deleting
256 branches or tags with
260 Deleting arbitrary references with
262 may also leave unreferenced objects behind.
264 In order to determine the set of objects which are referenced, search
265 all references for commit objects and tag objects, and traverse the
266 corresponding tree object hierarchies.
267 Any loose object IDs not encountered during this search are unreferenced
268 and thus subject to removal.
269 Display the number of commits which have been searched to indicate progress.
273 namespace may prevent objects from being purged.

287 will only purge corresponding objects once such references have been
291 Some Git repositories contain pack index files which lack a corresponding
292 pack file, which is an inconsistent repository state.
294 .Cm gotadmin cleanup -p -n
295 will display a list of affected pack index files.
296 Whenever possible, the missing pack files should be restored.
297 If restoring missing pack files is not possible, then affected pack index
298 files can be removed with
299 .Cm gotadmin cleanup -p .
303 Git extension is intended to prevent the removal of objects from a repository.
305 will refuse to operate on repositories where this extension is active.
312 Delete all loose objects.
313 By default, objects which are newer than an implementation-defined
314 modification timestamp are kept on disk to prevent race conditions
315 with other commands that add new objects to the repository while
319 Display the usual progress output and summary information but do not actually
320 remove any files from disk.
322 Instead of purging unreferenced loose objects, remove any pack index files
323 which do not have a corresponding pack file.
325 Suppress progress reporting and disk space summary output.
