Subject: [PATCH] Fix python ts.addErase() not raising exception on not-found
|
|
|
787856 |
packages
|
|
|
787856 |
|
|
|
787856 |
The code would only raise an exception if TransactionSetCore.addErase()
|
|
|
787856 |
returned an error, but the catch is that with many kinds of argument
|
|
|
787856 |
types we'd silently skip the whole addition because no headers were found.
|
|
|
787856 |
This looks to be a regression introduced some eleven years ago in
|
|
|
787856 |
commit 9b20c706a4f93266450fae2f94007343b2e8fd9e.
|
|
|
787856 |
|
|
|
787856 |
As a special case, a match iterator argument will not raise an exception
|
|
|
787856 |
if it doesn't actually match anything.
|
|
|
787856 |
|
|
|

Fixes: #1214
