uncheckout

Cancels a checkout of an element

APPLICABILITY

ClearCase (cleartool subcommand), Attache (command)

SYNOPSIS

uncheck·out | unco [ -kee·p | -rm ] [ -cact ] pname ...

DESCRIPTION

The uncheckout command cancels a checkout for one or more elements, deleting the checked-out version. Any metadata (for example, attributes) that you attached to a checked-out version is lost. After you cancel a checkout:

• A dynamic view reverts to selecting a checked-in version of each element.
• A snapshot view performs an update operation for each unchecked-out element. (For snapshot views, there is an exception for the canceling of a directory checkout; see Canceling a Directory Checkout for more information).

In Attache, if -rm is not specified, any corresponding local files are uploaded before the uncheckout command is executed remotely, so that they can be kept in the view if -keep is specified or if the keep query receives a yes answer. Local files that correspond to canceled checkouts are updated from the version selected by the view after the checkouts are canceled, and are made read-only.

The checkout version event record for each element is removed from its VOB's database. (There is no uncheckout event record.) Reserve and unreserve records are also removed.

If you checked out a file under an alternate name (checkout -out), you cannot use the alternate name to cancel the checkout-you must use the element name listed by ls -vob_only.

Canceling a Checkout in an Inaccessible View

(ClearCase only) You can cancel another dynamic view's checkout by using a view-extended pathname to the element. But for a snapshot view, or in the case where a dynamic view is no longer accessible (for example, it was deleted accidentally), a view-extended pathname does not work. Instead, do the following:

1. Enter the command describe -long vob:pname-in-vob, where pname-in-vob is the VOB-tag of the VOB containing the checked-out file. The output of this command includes a list of views with checkouts in the VOB.
2. Look for the view-storage pathname of the inaccessible view, and note the view's unique identifier (UUID).
3. Use the uuid in the command rmview -uuid uuid to remove all of the view's checkout records from the VOB.
4. Repeat Step #3 in each VOB that may have been accessed with the view.

You can also change reserved checkouts in that view to unreserved. There is no way to cancel checkouts in an inaccessible view.

Canceling a Directory Checkout

If you cancel a directory's checkout in a dynamic view after changing its contents, the changes made with rmname, mv, and ln are lost. Any new elements that were created (with mkelem or mkdir) become orphaned; such elements are moved to the VOB's lost+found directory, stored under names of this form:

element-name.UUID

uncheckout displays a message in such cases:

cleartool: Warning: Object "foo.c" no longer referenced.
cleartool: Warning: Moving object to vob lost+found directory as
"foo.c.5f6815a0a2ce11cca54708006906af65".

When you use uncheckout in a snapshot view, the changes made with rmname, mv, and ln are lost in the VOB because there is no lost+found directory, but the snapshot view does not reflect the VOB contents until you invoke update.

PERMISSIONS AND LOCKS

Permissions Checking: For each object processed, you must be one of the following: version creator, element owner, VOB owner, member of the ClearCase group. See the permissions reference page.

Locks: An error occurs if any of the following objects are locked: VOB, element type, element, branch type, branch.

OPTIONS AND ARGUMENTS

HANDLING OF THE FILE.  Default: For file elements only, uncheckout prompts you to decide whether to preserve a copy of the checked-out version of the element:

Save private copy of "util.c"? [yes]

A yes answer is equivalent to specifying the -keep option; a no answer is equivalent to specifying the -rm option.

-kee·p

Preserves the contents of the checked-out version (in Attache, in the view) under a file-name of the form element-name.keep (or, to prevent name collisions, element-name.keep.1, element-name.keep.2, and so on). This file is not downloaded to the Attache workspace.

-rm

Does not preserve the contents of the checked-out version. Thus, any edits that had been made to the checked-out version are lost.

-cact

Cancels the checkout for each checked out version in the current activity.

SPECIFYING THE ELEMENT.  Default: None.

pname ...

One or more pathnames, each of which specifies an element. The checkout in the current view is canceled, unless you use a view-extended pathname to specify another view.

NOTE: Avoid using a version-extended pathname. For example, you cannot use hello.c@@\main\sub1 to cancel another view's checkout on the sub1 branch of element hello.c.

EXAMPLES

Examples including wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the command interpreter prompt. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt. In Attache, cmd-context represents the workspace prompt.

• Cancel the checkout of file element util.c.

cmd-context uncheckout util.c

Save private copy of "util.c"? [yes] no
Checkout cancelled for "util.c".

• (ClearCase dynamic view only) Cancel the checkout of file hello.h in the jackson_fix view, and delete the view-private copy.

cmd-context uncheckout -rm M:\jackson_fix\users_hw\src\hello.h

Checkout cancelled for "M:\jackson_fix\users_hw\src\hello.h".

• Cancel the checkout of directory subd after creating a new element named conv.c. Because the context for this command is a dynamic view, the element is moved to the VOB's lost+found directory.

cmd-context uncheckout subd

cleartool: Warning: Object "conv.c" no longer referenced.
cleartool: Warning: Moving object to vob lost+found directory as
"conv.c.3d90000112fc11cba70e0800690605d8".
Checkout cancelled for "subd".
