DESCRIPTION

This command provides low-level access to refs.

COMMANDS

migrate

Migrate ref store between different formats.

verify

Verify reference database consistency.

list

List references in the repository with support for filtering, formatting, and sorting. This subcommand is an alias for git-for-each-ref(1) and offers identical functionality.

OPTIONS

The following options are specific to git refs migrate:

--ref-format=<format>

The ref format to migrate the ref store to. Can be one of:

  • files for loose files with packed-refs. This is the default.

  • reftable for the reftable format. This format is experimental and its internals are subject to change.

--dry-run

Perform the migration, but do not modify the repository. The migrated refs will be written into a separate directory that can be inspected separately. The name of the directory will be reported on stdout. This can be used to double check that the migration works as expected before performing the actual migration.

--reflog
--no-reflog

Choose between migrating the reflog data to the new backend, and discarding them. The default is "--reflog", to migrate.

The following options are specific to git refs verify:

--strict

Enable stricter error checking. This will cause warnings to be reported as errors. See git-fsck(1).

--verbose

When verifying the reference database consistency, be chatty.

The following options are specific to git refs list:

<pattern>…​

If one or more patterns are given, only refs are shown that match against at least one pattern, either using fnmatch(3) or literally, in the latter case matching completely or from the beginning up to a slash.

--stdin

If --stdin is supplied, then the list of patterns is read from standard input instead of from the argument list.

--count=<count>

By default the command shows all refs that match <pattern>. This option makes it stop after showing that many refs.

--sort=<key>

A field name to sort on. Prefix - to sort in descending order of the value. When unspecified, refname is used. You may use the --sort=<key> option multiple times, in which case the last key becomes the primary key.

--format=<format>

A string that interpolates %(fieldname) from a ref being shown and the object it points at. In addition, the string literal %% renders as % and %xx - where xx are hex digits - renders as the character with hex code xx. For example, %00 interpolates to \0 (NUL), %09 to \t (TAB), and %0a to \n (LF).

When unspecified, <format> defaults to %(objectname) SPC %(objecttype) TAB %(refname).

--color[=<when>]

Respect any colors specified in the --format option. The <when> field must be one of always, never, or auto (if <when> is absent, behave as if always was given).

--shell
--perl
--python
--tcl

If given, strings that substitute %(fieldname) placeholders are quoted as string literals suitable for the specified host language. This is meant to produce a scriptlet that can directly be `eval`ed.

--points-at=<object>

Only list refs which points at the given object.

--merged[=<object>]

Only list refs whose tips are reachable from the specified commit (HEAD if not specified).

--no-merged[=<object>]

Only list refs whose tips are not reachable from the specified commit (HEAD if not specified).

--contains[=<object>]

Only list refs which contain the specified commit (HEAD if not specified).

--no-contains[=<object>]

Only list refs which don’t contain the specified commit (HEAD if not specified).

--ignore-case

Sorting and filtering refs are case insensitive.

--omit-empty

Do not print a newline after formatted refs where the format expands to the empty string.

--exclude=<pattern>

If one or more patterns are given, only refs which do not match any excluded pattern(s) are shown. Matching is done using the same rules as <pattern> above.

--include-root-refs

List root refs (HEAD and pseudorefs) apart from regular refs.

--start-after=<marker>

Allows paginating the output by skipping references up to and including the specified marker. When paging, it should be noted that references may be deleted, modified or added between invocations. Output will only yield those references which follow the marker lexicographically. Output begins from the first reference that would come after the marker alphabetically. Cannot be used with --sort=<key> or --stdin options, or the <pattern> argument(s) to limit the refs.

KNOWN LIMITATIONS

The ref format migration has several known limitations in its current form:

  • It is not possible to migrate repositories that have worktrees.

  • There is no way to block concurrent writes to the repository during an ongoing migration. Concurrent writes can lead to an inconsistent migrated state. Users are expected to block writes on a higher level. If your repository is registered for scheduled maintenance, it is recommended to unregister it first with git-maintenance(1).

These limitations may eventually be lifted.
