node.js - MongoDB update/insert whole collection (array) -


i've got collection of items,

[     {         itemid: 1249,         somefield: 'abc'     },     {         itemid: 1479,         anotherfield: 'bcc'     }     ,     // etc ]

i recieve portion of data. of items there, not,

[     {         itemid: 6534,         somefield: 'trw'     },     // stored in collection..     {         itemid: 1249,         somefield: 'abc'     } ]

i'm looking way of bulk insert of data upsert strategy (means, if item such itemid there - update, otherwise insert).

is possible 1 query, of need go throught collection manually , upsert each item?

i use this, not effecent method, works

mongoclient.connect("mongodb://localhost:27017/devbed", {native_parser:true}, function(err, db) {     db.collection(project.name).findone({"revision":project.tmprev}, function(err,item){                         if(item){                           db.collection(project.name).update({json},{w:1},function(err, object) {                               if (err) {console.warn(err.message);}                               else {console.log("succesfully saved");                               db.close();}                           });                         }                         else{                             db.collection(project.name).insert({json}]},{w:1},function(err, object) {                             if (err) {console.warn(err.message);}                             else {console.log("succesfully saved");                             db.close();}                             });                         }                      }); });

wraping in function should work

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
