> Python version mismatch check and patch level revisions.
> --------------------------------------------------------
>
> Key: MODPYTHON-205
> URL: https://issues.apache.org/jira/browse/MODPYTHON-205
> Project: mod_python
> Issue Type: Bug
> Components: core
> Affects Versions: 3.3.x, 3.2.10
> Reporter: Graham Dumpleton
> Priority: Minor
>
> When mod_python starts up, it performs a check to confirm whether the version
> of Python it finds at runtime is the same version as was used to compile
> mod_python originally. It does this by comparing the value of PY_VERSION
> defined when mod_python is compiled against the runtime derived version from
> Py_GetVersion().
> Because this is a complete version string, it incorporates the patch level
> revision as well as the major and minor versions. This means mod_python will
> issue a warning if Python has been updated, but only by a patch revision.
> Technically, the ABI for patch level revisions of Python should be compatible
> and a warning about a version mismatch should be needed in this situation.
> Thus, the check should perhaps be changed to only look at major/minor version
> differences and not patch level revisions.
> As an example of this issue, below is bug report from debian bugs list.
> Package: libapache2-mod-python
> Version: 3.2.10-2
> Severity: critical
> Justification: breaks unrelated software
