-
productmd.common.
create_release_id
(short, version, type, bp_short=None, bp_version=None, bp_type=None)¶ Create release_id from given parts.
Parameters: - short (str) – Release short name
- version (str) – Release version
- version – Release type
- bp_short (str) – Base Product short name
- bp_version (str) – Base Product version
- bp_type – Base Product type
Return type: str
-
productmd.common.
parse_release_id
(release_id)¶ Parse release_id to parts: {short, version, type} or {short, version, type, bp_short, bp_version, bp_type}
Parameters: release_id (str) – Release ID string Return type: dict
-
productmd.common.
is_valid_release_short
(short)¶ Determine if given release short name is valid.
Parameters: short (str) – Release short name Return type: bool
-
productmd.common.
is_valid_release_version
(version)¶ Determine if given release version is valid.
Parameters: version (str) – Release version Return type: bool
-
productmd.common.
split_version
(version)¶ Split version to a list of integers that can be easily compared.
Parameters: version (str) – Release version Return type: [int] or [string]
-
productmd.common.
get_major_version
(version, remove=None)¶ Return major version of a provided version string. Major version is the first component of the dot-separated version string. For non-version-like strings this function returns the argument unchanged.
The
remove
parameter is deprecated since version 1.18 and will be removed in the future.Parameters: version (str) – Version string Return type: str
-
productmd.common.
get_minor_version
(version, remove=None)¶ Return minor version of a provided version string. Minor version is the second component in the dot-separated version string. For non-version-like strings this function returns
None
.The
remove
parameter is deprecated since version 1.18 and will be removed in the future.Parameters: version (str) – Version string Return type: str
Classes¶
-
class
productmd.common.
MetadataBase
¶ -
validate
()¶ Validate attributes by running all self._validate_*() methods.
Raises: - TypeError – if an attribute has invalid type
- ValueError – if an attribute contains invalid value
-
load
(f)¶ Load data from a file.
Parameters: f (file or str) – file-like object or path to file
-
loads
(s)¶ Load data from a string.
Parameters: s (str) – input data
-
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
-
-
class
productmd.common.
Header
(parent, metadata_type)¶ This class represents the header used in serialized metadata files.
It consists of a type and a version. The type is meant purely for consumers of the file to know what they are dealing with without having to check filename. The version is used by productmd when parsing the file.
