) – Base product details (optional)
-
dump
(f)¶ Dump data to a file.
Parameters: f (file or str) – file-like object or path to file
-
dumps
()¶ Dump data to a string.
Return type: str
-
load
(f)¶ Load data from a file.
Parameters: f (file or str) – file-like object or path to file

VariantPaths
(variant)¶ This class stores paths for a variant in a tree. All paths are relative to .treeinfo location.
Binary
- packages – directory with binary RPMs
- repository – YUM repository with binary RPMs
Source
- source_packages – directory with source RPMs
- source_repository – YUM repository with source RPMs
Debug
- debug_packages – directory with debug RPMs
- debug_repository – YUM repository with debug RPMs
- Others
- identity – path to a pem file which identifies a product
Example:
variant = ... variant.paths.packages = "Packages" variant.paths.repository = "."
