bool lsst.dax.apdb.versionTuple.VersionTuple.checkCompatibility | ( | self, | |
VersionTuple | database_version, | ||
bool | update ) |
Compare implementation schema version with schema version in database. Parameters ---------- database_version : `VersionTuple` Version of the database schema. update : `bool` If True then read-write access is expected. Returns ------- compatible : `bool` True if schema versions are compatible. Notes ----- This method implements default rules for checking schema compatibility: - if major numbers differ, schemas are not compatible; - otherwise, if minor versions are different then newer version can read schema made by older version, but cannot write into it; older version can neither read nor write into newer schema; - otherwise, different patch versions are totally compatible.

VersionTuple lsst.dax.apdb.versionTuple.VersionTuple.fromString | ( | cls, | |
str | versionStr ) |
Extract version number from a string. Parameters ---------- versionStr : `str` Version number in string form "X.Y.Z", all components must be present. Returns ------- version : `VersionTuple` Parsed version tuple. Raises ------ ValueError Raised if string has an invalid format.
