Functionality bit 12
This portion of the license file contains the functionality bit to:
- Atomic Changes
Allow elements to be grouped together such that they must be checked out, checked-in, or unchecked out together as a group.
Any user can create or extend linked groups by linking any desired element so that any future checkout, checkin or uncheckout of any of the linked
Simply make the hyperlink type “atomic_change” in a VOB
with ClearTrigger applied and then anyone can link a file. Create the link type once in the
cleartool mkhltype –nc atomic_change
Then link elements together by using the native ClearCase
mkhlink command like so:
cleartool mkhlink –nc atomic_change foo.c@@ bar.c@@
cleartool mkhlink –nc atomic_change bar.c@@ cow.c@@
cleartool mkhlink –nc atomic_change cow.h@@ cow.c@@
It does not matter when the elements are linked or how many
or the direction of the links. The
linked family is "headless" so that if John knows of an association between
bar.c and cow.c and creates a link and Robert knows of a association between
cow.h and cow.c and Kathy creates a link between foo.c and bar.c, all elements
are “equally” linked such that if Tomas checks out any of the files, they can
all checked out.
By default if the bit is enabled, when a user checks out a linked file they might see
a dialog similar to the one below that "forces" them of the association and provides
them the opportunity checkout all of the elements, checkout just the single element
or cancel the attempt. The default selection is the "Yes" button – to check them all out.
If the region policy make has turned on the "Atomic Change" bit (bit 12) then only
the "yes" and "cancel" option is given. The elements are checked out together by “force” or the checkout is canceled.
To change the personality of this bit such that the user is given a choice between
"yes", "no" or "cancel" then just set the special purpose cleartrigger_alias
ABS_bit_12_personality in the clearbits file to "choice". The alias can be set
to "choice" or "force" (default is "force"). For example, a user creating a new
directory when the cleartrigger_alias ABS_bit_12_personality is set to "choice" would see output like that below:
The default selection is the "Yes" button – to check them
The elements do not have to be in the same directory and
are not limited to files.
Valid values for this bit are defined below:
