Stickiness
Stickiness is an important concept in CVS, especially when talking about tagging and branching. Stickiness is primarily internal to CVS, but it affects what can be done in a sandbox.
When a file in a sandbox has a persistent state that is not the
default state in the repository, the persistent state is said to be
sticky. A sandbox copy of a file can be set to a
specific revision, belong to a branch, or have specific keyword
options. Any of these things can cause a file to be sticky.
A file can be set to a specific revision by being retrieved from the
repository with a tag, revision number, or date. If the file is
retrieved with a date, it is said to have a sticky
date. If it is retrieved with a tag, it is said to have a
sticky tag
, and if it is retrieved with a revision
number, it is said to have a sticky revision.
Along the same lines, a sandbox file that belongs to a branch is said
to have a sticky
branch
, and a sandbox file with
sandbox-specific keywords has sticky
keywords
.
A sticky state applies to all commands run on the file. A file with a sticky date, revision, or nonbranch tag will not be updated to a more recent copy; nor can such files be committed. A file with a sticky branch is always committed to or updated from the branch in question.
Sticky states on a file can be viewed with cvs
status. For example, use the command cvs status
index.htm to see the status for the
index.htm file. Example 4-8
shows a cvs status report that lists a sticky
branch.
