 402018-08-08T07:28:19  <jonasschnelli> what is the best strategy to deserialize a varlen string from a stream with unknown length (burst read)
 412018-08-08T07:29:01  <jonasschnelli> NetMessage reads in bytes with unknown length, so it is unknown if the varstring is complete in buffer
 422018-08-08T07:29:43  <jonasschnelli> I'd like to figure out if the all bytes for the varlen-string are copied to the buffer

 472018-08-08T08:16:38  <wumpus> jonasschnelli: I'm confused--the normal varstring is unknown length isn't it?
 482018-08-08T08:16:45  <wumpus> fanquake: thanks will take a look
 492018-08-08T08:17:33  <jonasschnelli> wumpus: the problem is more complicated. I'm reading in bytes from a socket and I'd like to deserialize a varstring,... but need to know how many bytes I need to read from the socket
 502018-08-08T08:18:06  <jonasschnelli> So I need to look at the varint part of the varstring to know when I have finished readin the buffer that contains the whole varstring
 512018-08-08T08:18:17  <jonasschnelli> Since it can be 1 byte to n bytes
 522018-08-08T08:18:31  <jonasschnelli> not n but a verstring of 64bit length
 532018-08-08T08:21:19  <wumpus> the only way to do that would be to have a fixed-sized header that specifies the length to read, although this is typically DoS-prone especially if the buffer is allocated at once and remote can specify a very large buffer

 552018-08-08T08:22:16  <jonasschnelli> wumpus: Yes. But nevermind. I think i'm creating a non-existing problem
 562018-08-08T08:22:30  <jonasschnelli> I'm implementing BIP151 message structures: https://github.com/bitcoin/bips/blob/master/bip-0151.mediawiki#encrypted-messages-structure
 572018-08-08T08:23:07  <jonasschnelli> And the varstring command made me some problems... But I forgot that the inner message structure is always present at complete length (since it's MAC has must been checked beforehand)
