description |
[Impact]
* Users of studio-controls have been reporting bugs against studio-controls upstream on Github. For reference, see https://github.com/ovenwerks/studio-controls/issues/43
* Per the bug report, the following error is being thrown: SystemError: ffi_prep_closure(): bad user_data (it seems that the version of the libffi library seen at runtime is different from the 'ffi.h' file seen at compile-time)
* Based on this error, and based on the build time of python-cffi, it appears as though python-cffi was built on an older version of cffi. This explains the error.
[Test Case]
* A certain number of users have reported that simply running studio-controls causes this error.
[Where problems could occur]
* Since this is a no-change rebuild being requested, the possibility of breakage is slim to none. We are introducing no new changes here, but rather, resolving a regression that happened as a result of a newer version of cffi being introduced without a rebuild of dependencies.
* If any problems happen, it would be a result of applications using python-cffi and expecting this bug with built-in workarounds. I can't imagine such a case exists, so this is just a stretch. |
