Instead, the `try_risky_comparison` method is provided, which may return an error if two LooseVersions are 'incomparible'. For example when integer and string version components are present in the same position. Differences with old distutils.version.LooseVersion: (https://github.com/python/cpython/blob/v3.10.0/Lib/distutils/version.py#L269) Most version comparisons should give the same result. However, if a version has multiple trailing zeroes, not all of them are used in the comparison. This ensure that, for example, "2.0" and "2.0.0" are equal. version_stringreturnNc t j | D cg c] }|r|dk7 r| }}t | D ] \ }} t | ||< || _ yc c}w # t $ r Y /w xY w)zhParses a version string into its components. :param str version_string: version string .N)_VERSION_COMPONENT_REsplit enumerateint ValueErrorversion_components)selfr( x componentsiobjs r! __init__zLooseVersion.__init__B s} "7!<!<^!L 1!LA!"qCx !L 1 +FAs #C 1 , #- 1 s AA A%$A%otherc t j | j |j d D ] \ }}||k r y||kD s y y# t $ r0 t dj | j |j w xY w)a Compares the LooseVersion to another value. If the other value is another LooseVersion, the version components are compared. Otherwise, an exception is raised. Comparison is performed element-wise. If the version components being compared are of different types, the two versions are considered incomparible. Otherwise, if either of the components is not equal to the other, less or greater is returned based on the comparison's result. In case the two versions are of different lengths, some elements in the longer version have not yet been compared. If these are all equal to zero, the two versions are equal. Otherwise, the longer version is greater. If the two versions are incomparible, an exception is raised. Otherwise, the returned integer indicates the result of the comparison. If self == other, 0 is returned. If self > other, 1 is returned. If self < other -1 is returned. Examples: Equality: - LooseVersion('1.0').try_risky_comparison(LooseVersion('1.0')) -> 0 - LooseVersion('2.0.0a').try_risky_comparison(LooseVersion('2.0.0a')) -> 0 Inequality: - LooseVersion('2.0.0').try_risky_comparison(LooseVersion('1.0')) -> 1 - LooseVersion('1.0.1').try_risky_comparison(LooseVersion('2.0a')) -> -1 Incomparability: - LooseVersion('1a').try_risky_comparison(LooseVersion('1.0')) -> ValueError r ) fillvalue z~Cannot meaningfully compare LooseVersion {} with LooseVersion {} due to comparison of version components with different types.) itertools zip_longestr1 TypeErrorr0 format)r2 r8 self_vcother_vcs r! try_risky_comparisonz!LooseVersion.try_risky_comparisonR s 6 Y%.%:%:4;R;R;@;S;SEF&H!

But Certbot sometimes calls out to external programs, since it uses classic confinement. When we do that, we must modify the env to remove our modifications so it will use the system's libraries, since they may be incompatible with the versions of libraries included in the Snap. For example, apachectl, Nginx, and anything run from inside a hook should call this function and pass the results into the ``env`` argument of ``subprocess.Popen``. :returns: A modified copy of os.environ ready to pass to Popen :rtype: dict SNAPCERTBOT_SNAPPED)PATHLD_LIBRARY_PATH:c 3 2 K | ] }d |vs | yw)rF Nr ).0r3 envs r! <genexpr>z1env_no_snap_for_external_calls.<locals>.<genexpr> s! %c1JAcRXkabNba1Js )r environcopyjoinr- ) path_namerM s @r! env_no_snap_for_external_callsrS sj **// C S -S 8 0 XX%cY 1E1Ec1J%c cC N 1 Jr paramslogc t j | dt j t j dt }|j dk7 rKddj | d|j d |j } || t j | |j |j fS # t t f$ r2 ddj | z } || t j | w xY w) zRun the script with the given params. :param list params: List of parameters to pass to subprocess.run :param callable log: Logger method to use for errors FT)checkstdoutstderruniversal_newlinesrM z Unable to run the command: %s r zError while running z. ) subprocessrunPIPErS OSErrorr0 rQ r SubprocessError returncoderX rY )rT rU procmsgs r! run_scriptre s *~~f$)%/__%/__15"@"B D !
