I have an app that runs some very CPU / database intensive tasks and I started running into problems when I'd run more than one of these processes at the same time, so I implemented a cached flag that just says "hold on, another process has called dibs for the moment" that delays all other processes trying to do potentially conflicting / overloading stuff. |

there's no such things as bad ideas |

I suppose that's just what I tend to say when I anticipate there being a more elegant solution I haven't figured out yet and want to at least look self-aware. :slightly_smiling_face: |

@phantomwatson why is it hacky |
| # |
Apr 23rd 2019, 15:41 |
phantomwatson |
Kind of hacky. |

How do people do job queuing (those that actually do this kind of thing in their apps^^) when you have limited resources per server and some more expensive tasks? we have some 2GB composer update, and we need to limit simultaneous runs here per queue server (either per job type or by cost of those tasks in general). I have to extend my plugin here, just wondering how the other solutions handle this kind of thing in (Cake)PHP. I didnt see |

Actually, I have an important queue issue to solve. |

@phantomwatson Hopefully you can learn it before implementing it into prod :P |

i have the feeling @dereuromark has something very interesting to add to the conversation |

Yeah good idea, I’ll ask the user with their primary key is |

josbeir |
i'm no expert tho |
| # |
Apr 23rd 2019, 15:36 |
josbeir |
you should lookup your db row with some other identifier and do the comparison after fetching |

Huh. I also assumed that it would always be the same output for the same input. |

Note `$iv = openssl_random_pseudo_bytes($ivSize);` |
| # |
Apr 23rd 2019, 15:34 |
phantomwatson |
Oh, I'm just now seeing ``` public static function encrypt($plain, $key) { $method = 'AES-256-CBC'; $ivSize = openssl_cipher_iv_length($method); $iv = openssl_random_pseudo_bytes($ivSize); return $iv . openssl_encrypt($plain, $method, $key, OPENSSL_RAW_DATA, $iv); } ``` |

I don’t fancy reading and decrypting my whole database table |
| # |
Apr 23rd 2019, 15:34 |
josbeir |
yeah, i get that |
| # |
Apr 23rd 2019, 15:33 |
neon1024 |
I certainly didn’t, but I did totally miss the fact that encryption does not produce consistant output |
| # |
Apr 23rd 2019, 15:32 |
josbeir |
people always confuse encryption with hashing |
| # |
Apr 23rd 2019, 15:32 |

@josbeir `ctype_xdigit($value)` |

Apr 23rd 2019, 15:32 |

yes |
