I have removed checks for the Id and UpdatedAt fields from validateSilence. There are two reasons for this:
- I have moved validation of silences to the start of the function before the
IdandUpdatedAtfields are assigned. This is to fix the issue where an existing silence is expired but the new silence is not created. - These fields are supposed to be set in
silences.Set(*pb.Silence). These are not supposed to be user-editable fields. We assert that these are present within tests, but should not need to validate internal fields that the user cannot change.

This is to cover the following test case https://github.com/prometheus/alertmanager/blob/v0.27.0/silence/silence_test.go#L342.

We have unit tests that check UpdatedAt is not zero.

This test fails in main because the original silence is expired.

Will rebase #3899 to show that no behavior has changed. |

This commit fixes a bug where an invalid silence causes incomplete updates of existing silences. This is fixed moving validation out of the setSilence method and putting it at the start of the Set method instead. Signed-off-by: George Robinson <george.robinson@grafana.com>

This commit fixes the following bugs in silences: - prometheus/alertmanager#3877 - prometheus/alertmanager#3898 - prometheus/alertmanager#3897 which could cause an existing silence to be deleted/expired when updating the silence failed. This could be because the replacing silence exceeded limits or was invalid.

This commit fixes a bug where an invalid silence causes incomplete updates of existing silences. What happens here is in some cases where the new silence is invalid, it can expire the old silence without creating the new silence. What should happen instead is the entire operation is aborted, and the original silence is left in place. This has been fixed by moving validation out of the
setSilencemethod and putting it at the start of theSetmethod instead.
