[sanlock] 08/08: python: Fail with ValueError if disk path is too long
by pagure＠pagure.io 25 Jun '19

25 Jun '19

This is an automated email from the git hooks/post-receive script. nsoffer pushed a commit to branch master in repository sanlock. commit 53f7f0284c084ac2e4542fd1f71d0406075adb5d Author: Nir Soffer <nsoffer(a)redhat.com> AuthorDate: Sun Jun 16 22:36:39 2019 +0300 python: Fail with ValueError if disk path is too long Previously if a path was too long, we truncated the path silently. This probably fail when sanlock try to access non-existing path with "No such path or directory" error. If you are unlucky, this could try to access the wrong path, failing with bogus error, returning wrong data, or worse, writing a resource into the wrong location, destroying existing data. Now we fail immediately with: ValueError: Path is too long: '/too/long/path/...'

[sanlock] 03/08: python: Streamline initexception

This is an automated email from the git hooks/post-receive script. nsoffer pushed a commit to branch master in repository sanlock. commit f5c5b73895b68d8c6fd032a4fd5f98a9e5fb8a4a Author: Nir Soffer <nsoffer(a)redhat.com> AuthorDate: Sun Jun 16 20:15:36 2019 +0300 python: Streamline initexception When we create the sanlock exception we create a function, create a method from the function, create a dict from the method, and finally create an exception from the dict. This simple flow does not require goto for cleanup. Creating a dict is simpler and less error prone using Py_BuildValue(). When we finish with unused pointers, it is safer to set them to NULL using Py_CLEAR(), ensuring that we don't access freed memory.
