� } | S) a� Create a SemanticVersion from a pip version string.
This method will parse a version like 1.3.0 into a SemanticVersion.
This method is responsible for accepting any version string that any
older version of pbr ever created.
Therefore: versions like 1.3.0a1 versions are handled, parsed into a
canonical form and then output - resulting in 1.3.0.0a1.
Pre pbr-semver dev versions like 0.10.1.3.g83bef74 will be parsed but
output as 0.10.1.dev3.g83bef74.
:raises ValueError: Never tagged versions sdisted by old pbr result in
just the git hash, e.g. '1234567' which poses a substantial problem
since they collide with the semver versions when all the digits are
numerals. Such versions will result in a ValueError being thrown if
any non-numeric digits are present. They are an exception to the
general case of accepting anything we ever output, since they were
never intended and would permanently mess up versions on PyPI if
ever released - we're treating that as a critical bug that we ever
made them and have stopped doing that.

Decrementing versions doesn't make a lot of sense - this method only
exists to support rendering of pre-release versions strings into
serialisations (such as rpm) with no sort-before operator.
The 9999 magic version component is from the spec on this - pbr-semver.

The default behaviour is to perform a patch level increment. When
incrementing a prerelease version, the patch level is not changed
- the prerelease serial is changed (e.g. beta 0 -> beta 1).
Incrementing non-pre-release versions will not introduce pre-release
versions - except when doing a patch incremental to a pre-release
version the new version will only consist of major/minor/patch.
:param minor: Increment the minor version.
:param major: Increment the major version.
:return: A new SemanticVersion object.

of the release before.

For documentation on version_info tuples see the Python
documentation for sys.version_info.
Since semver and PEP-440 represent overlapping but not subsets of
versions, we have to have some heuristic / mapping rules, and have
extended the releaselevel field to have alphadev, betadev and
candidatedev values. When they are present the dev count is used
to provide the serial.
- a/b/rc take precedence.
- if there is no pre-release version the dev version is used.
- serial is taken from the dev/a/b/c component.
- final non-dev versions never get serials.
