Bug #3244: Detection of last promise update seems to be broken
Correct a broken time range definition in the system promises that breaks the broken BDB detection
Description
Correct a broken time range definition in the system promises that breaks the broken BDB detection
"mtime => irange(2147483647, ago(0,0,0,1,0,0));" is a broken definition, that should be "mtime => irange(ago(0,0,0,1,0,0), now);"

NCH, please it's a Technical Review, but redmine does not want me to set that status.

Matthieu, I've made some remarks on the PR, could ou correct them ?

As I tried to say in my comment #1 above (but it got cut off somehow):
I'm pretty sure there is a reason why it was done that way around, to avoid an edge case where "now" is actually the start time of cf-agent, and the file is modified after that.
In a specific example: if I start cf-agent at 01:00:00, we have now=09:00:00 and "1 hour ago"=08:00:00. The logic of "!mtime" is then "any file created before 08:00:00 OR AFTER 09:00:00". And if cf-agent spends more than 1 second before testing this, the time is then 09:00:30 for example, it will match files created since cf-agent started.
So, unless we can prove that bug has been fixed in CFEngine, I don't think we should be reversing the logic.
Can you please explain what problem are you encountering with this, and why you want to change it? Or, if you reason to believe this bug is no longer present, please explain why.

As tested on the labo systems, the result was that the agent considered the file to be out of range, and thus deleting the cfengine database, at each run (so every 5 minutes) (as explained in the parent ticket)
Something must have been broken in the logic or somewhere
With the implementation being "cannot find file not between now and 1 hour ago", the result is as expected :
- if the file is older than one hour, the database get erased
- if the promises are updated, the database is not erased

Oh, OK. I didn't know we did parent/sub tickets for bugs, my bad.

- if the promises are updated, the database is not erased
OK, that all sounds good then.

Actually, we don't :)
Users have been a bit overzealous in the opening tickets

It's been deployed on orch-3 for test, and it seems ok
