Subject [jira] [Commented] (ETCH-278) EtchPacketizer isn't able to receive multiple Packages in one Buffer
Date Fri, 07 Mar 2014 12:39:44 GMT


Aaron Frueh commented on ETCH-278:

Thanks, you're completely right.

The problem I see is that after this happens the Buffer is corrupted. And we need to search
the remaining buffer for the SIG. If not, we lose all Packages until suddenly there is a package
with the Header at the beginning of the Package.

| Hea | der | Data ............ | Header | Data | 

We got half a Header in the savedBuffer. The complete Header is defect because of a wrong
SIG, so we have to discard that package but we don't know if another Header is still existing
inside of the remaining buffer. Even worse the next Header could be split up again. 

Damaged Package:
| Hea | der | Data ............ | He |
Next Package:
| ader | Data .... | .......

I will extend my suggestion to solve that issue. But i'm really not sure if this is handled
correctly in the other etch-Bindings.
