Bug 24153: Add a confirm flag to cleanup_database

How handy this will be, right?

This patch will change the behavior of this script as the --confirm flag
will now be required for effective changes.
Without --confirm and with --verbose you will see what could have done
the script in non dry-run mode.

Test plan:
Use different options of the script without the --confirm flag and have
a look at the output. It now tells you what would have been deleted if
the flag was passed.
Now use the --confirm flag and confirm that the changes are now
effective.

Comment 3 Koha Team University Lyon 3 2020-03-20 09:04:08 UTC
I've tested for Association KohaLa.
If you launch cleanup_database. pl without the --confirm flag, nothing is done, but with the confirm flag, it works.

Comment 5 Julian Maurice 2020-06-12 11:04:28 UTC
From what I understand this a breaking change. For instance, for users that run this script in a cronjob, it will suddenly stop working.
If the need is to have a dry-run mode, why not add a --dry-run option instead ?
Comment 6 Jonathan Druart 2020-06-12 11:21:27 UTC
Yes it will need to be advertised correctly in the release note.

I think it makes sense to force the --confirm flag to effectively make the changes, it's what we do in most of the other scripts.
Comment 7 Julian Maurice 2020-06-12 12:19:38 UTC

Can it be written now in "Text to go in the release notes" ? :-D

I agree that it makes sense. This script removes data so we should prevent unwanted data loss. I just don't like breaking changes :-)

I kind of like the `git clean` approach which requires a flag (-n, -f or -i), which forces users to read the documentation first. Maybe we can have similar behavior for scripts that remove data (just a thought for future scripts, not blocking)

Comment 10 Marcel de Rooy 2020-06-19 08:40:58 UTC
+# FIXME The output for dry-run mode needs to be improved
Yes. Agreed.

+    $tokens->delete if $confirm;
+    say sprintf "Removed %s expired OAuth2 tokens", $count if $verbose;
This might be confusing. Among other examples.

* perl misc/cronjobs/cleanup_database.pl -m 10 -v
Mail queue purge triggered for 10 days.
Use of uninitialized value $count in concatenation (.) or string at misc/cronjobs/cleanup_database.pl line 293.
 messages were deleted from the mail queue.

So uninitialized warning that we do not want.
But this example could serve to illustrate that even the wrong count could have been printed. Look at:
    if ( $confirm ) {
        $sth->execute($mail) or die $dbh->errstr;
        $count = $sth->rows;
    }
    print "$count messages were deleted from the mail queue.\nDone with message_queue purge.\n" if $verbose;
=> Since the count is not set, it could well be the count of a former statement !

I do not think that this is ready for production. Since we do not really support testing for many options, I do not see why this patch is useful.

The following line is:
# But non trivial changes to C4::Members need to be done before.

So cannot be done now.

> +    $tokens->delete if $confirm;
> +    say sprintf "Removed %s expired OAuth2 tokens", $count if $verbose;

What do you mean, can you detail? Do you mean the message could be improved (use of conditional) in dry-run mode?

I fixed the warning.

I wrote it for the pseudonymized transactions. The idea was to rework a bit the whole script and introduce a common pattern. That's why I implemented filter_by_last_update and use it all over the script.
We now have a base and a pattern to follow. It's not useful yet for all the options, but at least it is for few of them.

Yeah, this holds in general. It might be confusing to say deleted when you are in dry run mode.

Cool. But are you confident that it is the only location where it could happen? Block X filled $count. And block Y presents it as a result while it actually comes from X.
Comment 14 Marcel de Rooy 2020-06-24 12:39:06 UTC
Another observation: We need to adjust the cron tab files and examples to add this flag.
