Method Details

[hide private]

Converts this (relative) change set to an abstract change set. File streams and contents are omitted unless the file changed. This is fine for changesets being committed, not so hot for changesets which are being applied directly to a system. The absolute changeset is returned as a new changeset; self is left unchanged.

rootChangeSet(self, db, troveMap)

source code

Converts this (absolute) change set to a relative change set. The second parameter, troveMap, specifies the old trove for each trove listed in this change set. It is a dictionary mapping (troveName, newVersion, newFlavor) tuples to (oldVersion, oldFlavor) pairs. The troveMap may be (None, None) if a new install is desired (the trove is switched from absolute to relative to nothing in this case). If an entry is missing for a trove, that trove is left absolute.

Rooting can happen multiple times (only once per trove though). To allow this, the absolute file streams remain available from this changeset for all time; rooting does not remove them.
