endianness - Little-endian support in Netty 4 -

-
the new & noteworthy docs netty 4 state support little-endian -ness has changed significantly, going on show use of bytebuf.order() . whilst that's useful localised use within channel handlers, whole downstream pipeline use little-endian buffers. the upstream handler lengthfieldbasedframedecoder takes constructor argument byte order, downstream handler lengthfieldprepender not. appears support configuration-driven replacement of buffer factories has gone netty 4, how should arrive @ complete little-endian downstream pipeline? i did this, though feels awfully hacky: https://gist.github.com/thomaslee/7871444 if wire in pipeline after lengthfieldprepender run, rewrite (big endian) length field using little endian byte ordering. probably more efficient write length in little endian after measuring length of in & dropping lengthfieldprepender entirely rather adding step pipeline code has been lazily copied & can attest working. :) i love know if ...

Meteor: Disallow user from selecting id's when inserting documents -

when using mini-mongo insert documents collection user pass _id field , _id set on document long string or objectid (and doesnt collide existing id). doesnt seem sensible me. want _id of documents generated server, always, dont end db both strings (potentially of different length) , objectids exist _ids. is there simple way achieve this? right best can think of checking id in deny rule (where _id either set meteor or value user provided) , if it's not type/length want change it, requires checks avoid duplicate ids. not difficult seems overly complex basic this. reviewing response, here's answer: deny inserts. create method , collectioninsert(document) , checks if _id field specified. meteor.methods({ collectioninsert: function(document) { if (document && document._id) { delete document._id; } // returns _id generated return collection.insert(document); } }); in today's versions of meteor (0.8 , higher) server , client ...
