Detailed Description

 A specific patch version of a package.  This is not just
the package's "version" string; it also corresponds to the
particular patch version, which increments independently of
the "version".

			hostUrl,

Member Function Documentation

applyPatch()

applyPatch	(		self,
			origFile,
			patchFilename )

 Applies the named patch to the indicated original
file, storing the results in a temporary file, and returns
that temporary Filename.  Returns None on failure. 

cleanup()

cleanup

(

self

)

getFile()

getFile

(

self

)

 Returns the Filename of the archive file associated
with this version.  If the file doesn't actually exist on
disk, a temporary file will be created.  Returns None if
the file can't be recreated. 

getNext()

getNext	(		self,
			package )

 Gets the next patch in the chain towards this
package. 

getPatchChain()

getPatchChain	(		self,
			startPv,
			alreadyVisited = [] )

 Returns a list of patches that, when applied in
sequence to the indicated PackageVersion object, will
produce this PackageVersion object.  Returns None if no
chain can be found. 

getRecreateFilePlan()

getRecreateFilePlan	(		self,
			alreadyVisited = [] )

 Returns the tuple (startFile, startPv, plan),
describing how to recreate the archive file for this
version.  startFile and startPv is the Filename and
packageVersion of the file to start with, and plan is a
list of tuples (patchfile, pv), listing the patches to
apply in sequence, and the packageVersion object
associated with each patch.  Returns (None, None, None) if
there is no way to recreate this archive file.
