[Bro-Dev] [JIRA] (BIT-1159) type checking inconsistencies

[Seth Hall (JIRA)]

     [ https://bro-tracker.atlassian.net/browse/BIT-1159?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Seth Hall updated BIT-1159:
---------------------------

    Attachment: signature.asc


I actually avoid the parse time name resolution and tend toward runtime lookups with the dns bifs going on the assumption that Bro is an extremely long lived process and I’d rather not rely on a name lookup that happened a (potentially) long time ago.

> If you try to compare a count to a port directly, you get the following:
> {code}
> operands must be of the same type (1500/tcp < 2000)
> {code}
> but if you have a record, and mixup the types like so, it silently fails:
> {code}
> type PortRange: record {
>     min: port &default=1/tcp;
>     max: port &default=65535/tcp;
> };
> global pr = PortRange($min=1000,$max=2000);
> #CORRECT: global pr = PortRange($min=1000/tcp,$max=2000/tcp);
> event bro_init()
> {
>     print (pr$min <= 1500/tcp  && 1500/tcp < pr$max) ? "OK" : "NOTOK";
> }
> {code}
> {code}
> $ bro a.bro
> NOTOK
> {code}
