python - Tornado doesn't restart cleanly in supervisor -


i'm using tornado run flask app, , have shell script little work , runs app.

#!/usr/bin/env bash some_work more_work python /usr/share/theapp/theapp.py

i use supervisor manage little script. starting works fine (sudo supervisorctl start theapp.sh), when want restart, python subprocess doesn't exit , hangs around, occupying port , preventing startup again. i've tried adding traps ensure python code stopped when script stopped supervisor, hasn't worked. i've tried switching out tornado gevent's wsgi server , have had same problem. how should doing small script?

the term signal sent bash script theapp.sh , never received python process. can try stopasgroup option in program section of supevisor config, more compatible how bash (and other shells) handle signals[1].

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
