node.js mongodb query was working fine until replica set setup and result is null -


i have followed mongo documentation @ http://docs.mongodb.org/manual/tutorial/deploy-replica-set-for-testing/ setup replica set (3 instances only) in local windows machine. tested followings , works fine:

  1. inserted data , connect primary using robomongo , can see data
  2. stop primary , 1 of secondary take on primary , data there.
  3. brought the 1 stopped , secondary now.

my problems:

  1. when use robomongo connect of secondary can't see data although there.
  2. my query code below return null although there data in mongodb

the connection string (no authentication needed)

mongodb://mark2:27017,mark2:27018,mark2:27019/mydb?w=0&readpreference=secondary&replset=rs0

i rs.status() , shows 3 nodes active.

{         "_id" : "rs0",         "version" : 3,         "members" : [                 {                         "_id" : 0,                         "host" : "mark2:27017"                 },                 {                         "_id" : 1,                         "host" : "mark2:27018"                 },                 {                         "_id" : 2,                         "host" : "mark2:27019"                 }         ] }

the query simple query

db.collection("user").findone({email:"yummy@gmail.com"}, function(err, result) {         if(result) { // result null wasn't before setting replica set          } else {          }  });

appreciate advice please. !

cheerio, mark thien

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
