php - Crontab file is corrupted after remove an job on list? -

-

im using database controlled cronjobs newsletter. crontab job add / remove functions works fine, when remove job on list main trigger file not work properly. here workbench;

task list table;

id   campaign_id    remove  date                      cron_command  1        1            0     2015-04-22 17:00:00       * * * * * curl -s http://example.com/tasks.php?id=1

main trigger file (cron.php) checking table, if date reach current date add cron_command crontab, works fine here. tasks.php file works fine , send "id1" campaign mails.

after campaign task done , mails sent successfully, above record updated to

id   campaign_id    remove  date                      cron_command  1        1            1     2015-04-22 17:00:00       * * * * * curl -s http://example.com/tasks.php?id=1

main trigger file check remove 1 marked commands , should have remove record both side (crontab / db table). not remove command on crontab , db table, main trigger file gives error "php command error: no input file specified", "curl command error: 400 bad request", "wget command: ambiguous redirect"

crontab manager class

class crontab {      // in class, array instead of string standard input / output format.      // legacy way add job:     // $output = shell_exec('(crontab -l; echo "'.$job.'") | crontab -');      static private function stringtoarray($jobs = '') {         $array = explode("\r\n", trim($jobs)); // trim() gets rid of last \r\n         foreach ($array $key => $item) {             if ($item == '') {                 unset($array[$key]);             }         }         return $array;     }      static private function arraytostring($jobs = array()) {         $string = implode("\r\n", $jobs);         return $string;     }      static public function getjobs() {         $output = shell_exec('crontab -l');         return self::stringtoarray($output);     }      static public function savejobs($jobs = array()) {         $output = shell_exec('echo "'.self::arraytostring($jobs).'" | crontab -');         return $output;      }      static public function doesjobexist($job = '') {         $jobs = self::getjobs();         if (in_array($job, $jobs)) {             return true;         } else {             return false;         }     }      static public function addjob($job = '') {         if (self::doesjobexist($job)) {             return false;         } else {             $jobs = self::getjobs();             $jobs[] = $job;             return self::savejobs($jobs);         }     }      static public function removejob($job = '') {         if (self::doesjobexist($job)) {             $jobs = self::getjobs();             unset($jobs[array_search($job, $jobs)]);             return self::savejobs($jobs);         } else {             return false;         }     }  }

main trigger file cron.php

/* task list modifier */ $modchr = new crontab(); $optasks = $myconn->query("select * tasks order remove desc") or die(mysqli_error($myconn)); while($optasksrs = $optasks->fetch_assoc()){     /* remove crons */     if($optasksrs['remove']==1){         if($modchr->removejob($optasksrs['cron_command'])){             $myconn->query("delete tasks id=". $optasksrs['id'] ."");         }else{             echo('command not executed');         }     }     /* add crons */     else{         if($optasksrs['date']<=date('y-m-d h:i:s')){             $modchr->addjob($optasksrs['cron_command']);         }     } } $optasks->free();

shortly issue; cron.php file not work after add new cron job via shell, when try run cron.php file via browser works fine. whats wrong?

regards.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
