python-smartpm: Don't ignore error if RPM transaction fails without problems
SmartPM could misinterpret RPM transaction error as success,
if ts.run() (RPM Python API) returns an empty problems list.
This could happen for example if the RPM database is partially corrupted
such that the transaction does not have any problems like conflicts or
missing dependencies, but still can't be committed.
The added patch fixes the problem in the upstream sources;
one of the existing patches has to be adjusted to still apply.

5 | |||
6 | SmartPM could misinterpret RPM transaction error as success, | ||
7 | if ts.run() (RPM Python API) returns an empty problems list, | ||
8 | because of incorrect check for None which treated empty list | ||
9 | to be the same as None when it has different meaning. | ||
10 | |||
11 | ts.run() returns: | ||
12 | * None in case of success | ||
13 | * problems list in case of error, may be empty | ||
14 | (look at rpmts_Run() in rpm-5.4.14/python/rpmts-py.c [1]) | ||
15 | |||
16 | "if mylist" is not good enough to check for error here, because it will | ||
17 | treat an empty list as "false" because its len() == 0 [2]. | ||
18 | |||
19 | ts.check() seems to be different (it's ok for it to return an empty list), | ||
20 | but for consistency it should be made clear that it can return either None, | ||
21 | an empty list or a non-empty list. | ||
