perl - MariaDB replication some times does not working -


i have problem have never seen before mysql replication (master/slave): works excellent when execute on php scripts, on mysql console queries "insert into". replicated on mysql slave machine. but: not if same operations on perl script, using perl dbi. stored on mysql master server. in mysql.log file on slave server, nothing arrives. have problem since migrated on 2 servers mysql mariadb. there perl dbi client should absolutely replicating work?

i'm using simple code insert data:

#!/usr/bin/perl use dbi; $dsn = 'dbi:mysql:database=mysql;host=myhostname'; $dbh = dbi->connect($dsn, 'mouser', 'password',             { raiseerror => 1, autocommit => 0 }) || exit(1); ... $sth = $dbh->prepare("insert mydatabase.mytable (user, domain) values('$account_name', '$domain')"); $sth->execute(); $dbh->commit();

is possible not replicate because dbi should use mariadb driver? $dsn = 'dbi:mariadb:database=mysql;host=myhostname'; if exists?

to clear: data inserted php script still being replicated after switching mariadb, data inserted perl script isn't.

i found reason why replication failed simple perl script: there written:

$dsn = 'dbi:mysql:database=mysql;host=myhostname'; ... $sth = $dbh->prepare("insert mydatabase.mytable (user, domain) values('$account_name', '$domain')");

this not working, because dbi connects database "mysql" , not "mydatabase" (see "database=mysql"). if insert inserts row directly in database "mydatabase", mariadb master server ignores replication. strange worked mysql , not mariadb (version 5.5.46). maybe bug in mariadb, don't know.

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
