mysql - "mysql_clear_password" plugin error when using knex but not when using mysql2 -


i trying connect mysql server using mysql_clear_password plugin. set connection configuration node-mysql2 follows:

const connectionconfig = {   host: rwconfig.host,   user: rwconfig.user,   database: rwconfig.database,   ssl: {     ca: sslcontent   },   password }

then support mysql_clear_password plugin added following (link of reference used: https://github.com/sidorares/node-mysql2/issues/438#issuecomment-255343793):

connectionconfig.authswitchhandler = (data, cb) => {   console.log('in auth switch handler');   if (data.pluginname === 'mysql_clear_password') {     console.log(data);     console.log(data.plugindata.tostring('utf8'));     console.log('in mysql clear password');     var tmppassword = connectionconfig.password + '\0';     var buffer = buffer.from(tmppassword, 'base64');     cb(null, buffer);   } };

this works when attempt connect database.

now try similar using knexjs. use following configuration object:

const knexconfig = {   client: 'mysql2',   connection: connectionconfig,   pool: {     min: 0,     max: 20   },   acquireconnectiontimeout: 10000 };

the connectionconfig passed in value connection same object used connecting node-mysql2. create knex connection:

const rwconnection = knex(knexconfig);

this reason throws error:

{ error: client not support authentication protocol requested server; consider upgrading mysql client @ packet.aserror (node_modules/mysql2/lib/packets/packet.js:703:13) @ clienthandshake.command.execute (node_modules/mysql2/lib/commands/command.js:28:22) @ connection.handlepacket (node_modules/mysql2/lib/connection.js:515:28) @ packetparser.onpacket (node_modules/mysql2/lib/connection.js:94:16) @ packetparser.executestart (node_modules/mysql2/lib/packet_parser.js:77:14) @ tlssocket.<anonymous> (node_modules/mysql2/lib/connection.js:386:31) @ emitone (events.js:96:13) @ tlssocket.emit (events.js:188:7) @ readableaddchunk (_stream_readable.js:176:18) @ tlssocket.readable.push (_stream_readable.js:134:10) @ tlswrap.onread (net.js:547:20) code: 'er_not_supported_auth_mode', errno: 1251, sqlstate: '#08004' }

i don't know why giving me error. in knex documentation (http://knexjs.org/) says:

the connection options passed directly appropriate database client create connection, , may either object, or connection string

based on thought pass configuration through , make connection using node-mysql2. appreciated.

i figured out issue , works now. knex not passing on attributes msyql2 client.

here did else might run problem. modified configurations knex passing mysql2 in node_modules/knex/lib/dialect/mysql2 , added authswitchhandler configoptions array.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
