Ubuntu Manpage: gotadmin — Game of Trees repository administration

NAME

     gotadmin — Game of Trees repository administration

SYNOPSIS

     gotadmin [-hV] command [arg ...]

DESCRIPTION

gotadmin is the repository maintenance tool for the got(1) version control system.

got(1) stores the history of tracked files in a Git repository, as used by the Git version
control system. gotadmin provides commands for inspecting and manipulating the on-disk
state of Git repositories. The repository format is described in git-repository(5).

gotadmin provides global and command-specific options. Global options must precede the
command name, and are as follows:

-h Display usage information and exit immediately.

-V, --version
Display program version and exit immediately.

The commands for gotadmin are as follows:

init [-A hashing-algorithm] [-b branch] repository-path
Create a new empty repository at the specified repository-path.

After gotadmin init, the new repository must be populated before got checkout can
be used. The got import command can be used to populate the new repository with
data from a local directory. Alternatively, on a server running gotd(8), the new
repository can be made available to got(1) or git(1) clients by adding the
repository to gotd.conf(5) and restarting gotd(8). Clients may then clone the new
repository from the server, populate the cloned repository, and then populate the
new repository on the server via got send or git push.

The options for gotadmin init are as follows:

-A hashing-algorithm
Configure the repository's hashing-algorithm used for the computation of
Git object IDs. Possible values are sha1 (the default) or sha256.

-b branch
Make the repository's HEAD reference point to the specified branch instead
of the default branch “main”.

The gotadmin init command is equivalent to got init.

info [-r repository-path]
Display information about a repository. This includes some configuration settings
from got.conf(5), the object ID hashing algorithm, and the number of objects
stored in the repository, in packed or loose form, as well as the current on-disk
size of these objects.

The options for gotadmin info are as follows:

-r repository-path
Use the repository at the specified path. If not specified, assume the
repository is located at or above the current working directory. If this
directory is a got(1) work tree, use the repository path associated with
this work tree.

pack [-aDq] [-r repository-path] [-x reference] [reference ...]
Generate a new pack file and a corresponding pack file index. By default, add any
loose objects which are reachable via any references to the generated pack file.

If one or more reference arguments is specified, only add objects which are
reachable via the specified references. Each reference argument may either
specify a specific reference or a reference namespace, in which case all
references within this namespace will be used.

gotadmin pack always ignores references in the refs/got/ namespace, effectively
treating such references as if they did not refer to any objects.

The options for gotadmin pack are as follows:

-a Add objects to the generated pack file even if they are already packed in
a different pack file. Unless this option is specified, only loose
objects will be added.

-D Force the use of ref-delta representation for deltified objects. If this
option is not specified, offset-deltas will be used to represent deltified
objects.

-q Suppress progress reporting output.

-x reference
Exclude objects reachable via the specified reference from the pack file.
The reference argument may either specify a specific reference or a
reference namespace, in which case all references within this namespace
will be excluded. The -x option may be specified multiple times to build
a list of references to exclude.

Exclusion takes precedence over inclusion. If a reference appears in both
the included and excluded lists, it will be excluded.

indexpack packfile-path
(alias: ix)
Create a pack index for the pack file at packfile-path.

A pack index is required for using the corresponding pack file with got(1).
Usually, a pack index will be created by commands such as gotadmin pack or got
fetch as part of regular operation. The gotadmin indexpack command may be used to
recover from a corrupt or missing index. A given pack file will always yield the
same bit-identical index.

The provided packfile-path must be located within the objects/pack/ directory of
the repository and should end in .pack. The filename of the corresponding pack
index is equivalent, except that it ends in .idx.

listpack [-hs] packfile-path
(alias: ls)
List the contents of the pack file at packfile-path.

Each object contained in the pack file will be displayed on a single line. The
information shown includes the object ID, object type, object offset, and object
size.

If a packed object is deltified against another object, the delta base will be
shown as well. For offset deltas, the delta base is identified via an offset into
the pack file. For reference deltas, the delta base is identified via an object
ID.

The provided packfile-path must be located within the objects/pack/ directory of
the repository and should end in .pack. The corresponding pack index must exist
and can be created with gotadmin indexpack if it is missing.

The options for gotadmin listpack are as follows:

-h Show object sizes in human-readable form.

-s Display statistics about the pack file after listing objects. This
includes the total number of objects stored in the pack file and a break-
down of the number of objects per object type.

cleanup [-anpq] [-r repository-path]
(alias: cl)
Purge unreferenced loose objects and redundant pack files from the repository and
display the amount of disk space which has been freed as a result.

Unreferenced objects are present in the repository but cannot be reached via any
reference in the entire refs/ namespace. Objects will usually become unreferenced
as a result of deleting branches, tags, or other references with got branch -d,
got ref -d, or got fetch -X.

Loose objects are stored as individual files beneath the repository's objects/
directory, spread across 256 sub-directories named after the 256 possible
hexadecimal values of the first byte of an object identifier.

Packed objects are stored in pack files under objects/pack/.

If redundant copies of packed objects exist in loose form, such redundant copies
will be purged. If all the objects of a pack file are present in other pack
files, the redundant pack file will be purged. Pack files will usually become
redundant as a result of repacking the repository with gotadmin pack -a.

References in the refs/got namespace may prevent objects from being purged. This
includes references in the refs/got/worktree namespace created by got checkout and
got update, as well as references in the refs/got/backup namespace created by got
rebase and got histedit. gotadmin cleanup will only purge corresponding objects
once such references have been deleted with got rebase -X, got histedit -X, or got
ref -d.

The “preciousObjects” Git extension is intended to prevent the removal of objects
from a repository. gotadmin cleanup will refuse to operate on repositories where
this extension is active.

For compatibility with Git, if a file with the extension .keep exists and
corresponds to a pack file with the extension .pack then this pack file will not
be removed.

Some Git repositories contain pack index files which lack a corresponding pack
file, which is an inconsistent repository state. In such cases, gotadmin cleanup
-p -n will display a list of affected pack index files. Whenever possible, the
missing pack files should be restored. If restoring missing pack files is not
possible, then affected pack index files can be removed with gotadmin cleanup -p.

The options for gotadmin cleanup are as follows:

-a Delete all redundant loose and packed objects. By default, objects which
are newer than an implementation-defined modification timestamp are kept
on disk to prevent race conditions with other commands that add new
objects to the repository while gotadmin cleanup is running.

-n Display the usual progress output and summary information but do not
actually remove any files from disk.

-p Instead of purging unreferenced loose objects and redundant pack files,
remove any pack index files which do not have a corresponding pack file.

-q Suppress progress reporting and disk space summary output.

dump [-q] [-r repository-path] [-x reference] [reference ...]
Dump the contents of the repository to standard output in Git bundle format.

The options for gotadmin dump are as follows:

-q Suppress progress reporting output.

-x reference
Exclude objects reachable via the specified reference from the bundle.
The reference argument may either specify a specific reference or a
reference namespace, in which case all references within this namespace
will be excluded. The -x option may be specified multiple times to build
a list of references to exclude.

Exclusion takes precedence over inclusion. If a reference appears in both
the included and excluded lists, it will be excluded.

load [-nq] [-l bundle-path] [-r repository-path] [reference ...]
Read a Git bundle stream from standard input and load its data into a repository.

If one or more reference arguments are provided then only load the specified
references from the bundle. Otherwise, all references will be loaded.

The options for gotadmin load are as follows:

-l bundle-path
List references available for loading from the bundle at the specified
bundle-path and exit immediately. If the -l option is specified then no
reference arguments are allowed. The -l option is incompatible with the
-n option.

-n Attempt to load the bundle but don't install new packfile or update any
reference. Can be used to verify the integrity of the bundle.

-q Suppress progress reporting output.

EXIT STATUS

     The gotadmin utility exits 0 on success, and >0 if an error occurs.

CAVEATS

     gotadmin is a work-in-progress and some features remain to be implemented.

     At present, the user has to fall back on git(1) to perform some tasks.  In particular:

     •   Exporting data from repositories requires git-fast-export(1).

     •   Importing data into repositories requires git-fast-import(1).

BUGS

     Disk space savings reported by gotadmin cleanup will be misleading if the repository
     contains object files that were hard-linked from another repository.  Such hard-links will
     be created by certain git(1) commands.  By itself, got(1) will never create hard-linked
     object files.
