| vkmc | morning! | 11:13 |
|---|---|---|
| exploreshaifali | mornind vkmc | 11:13 |
| exploreshaifali | morning* | 11:14 |
| vkmc | hi there exploreshaifali, how are you doing? :) | 11:14 |
| exploreshaifali | yea, re that patch | 11:14 |
| exploreshaifali | I am sure it will give same error for controlDriver.message_controller attribute | 11:14 |
| vkmc | have you tried it? :) | 11:15 |
| exploreshaifali | I was making changes, it needs few more tests to be modified as from our last change in __init__ of DataDriver | 11:15 |
| exploreshaifali | made tests failed | 11:15 |
| vkmc | yeah, that for sure | 11:16 |
| exploreshaifali | but there is same case with ControlDriver too | 11:16 |
| vkmc | the thing is the server starts | 11:16 |
| vkmc | and that you can interact with the controllers | 11:16 |
| exploreshaifali | can we come to etherpad? | 11:16 |
| vkmc | do not run the tests when we make changes like these because they will need refactoring as well | 11:16 |
| vkmc | sure | 11:16 |
| vkmc | give me the lin | 11:16 |
| vkmc | k | 11:16 |
| exploreshaifali | https://etherpad.openstack.org/p/data-plane-control-plane | 11:16 |
| kragniz | exploreshaifali vkmc: good morning! | 11:18 |
| exploreshaifali | vkmc, at line 142 | 11:18 |
| exploreshaifali | kragniz, moooooooooooooooorning :D | 11:18 |
| *** flwang has quit IRC | 11:18 | |
| vkmc | kragniz, good morning! :) | 11:18 |
| exploreshaifali | vkmc, so last error was because we are using DataDriver.control_driver as in line 190 at https://review.openstack.org/#/c/144340/22/zaqar/storage/mongodb/driver.py | 11:21 |
| exploreshaifali | vkmc, in our implementation we have not defined control_driver inside DataDriver class that is why that error occured | 11:22 |
| exploreshaifali | right? | 11:22 |
| vkmc | give me a moment, I'll review | 11:23 |
| exploreshaifali | vkmc, this was the error http://paste.openstack.org/show/185073/ | 11:23 |
| exploreshaifali | than we decided to always pass control_driver also inside DataDriver __init__ | 11:24 |
| exploreshaifali | and define self.control_driver inside __init__ | 11:24 |
| *** flwang has joined #openstack-zaqar | 11:28 | |
| *** dynarro has joined #openstack-zaqar | 12:37 | |
| *** dynarro has quit IRC | 12:45 | |
| *** dynarro has joined #openstack-zaqar | 12:51 | |
| vkmc | exploreshaifali, so, you should add the control_plane here https://github.com/openstack/zaqar/blob/master/zaqar/storage/base.py#L98 | 12:52 |
| *** vromero has joined #openstack-zaqar | 12:54 | |
| exploreshaifali | vkmc, yes that is something already done in current patch https://review.openstack.org/#/c/144340/22/zaqar/storage/base.py | 12:54 |
| exploreshaifali | vkmc, we can do that, bbut now the problem is with message_controller that is needed by queue_controller | 12:54 |
| vkmc | sure | 12:55 |
| exploreshaifali | and not to forget queue_controller is now defined/initialized inside controlDriver | 12:55 |
| flaper87 | bu47 | 12:56 |
| flaper87 | ops | 12:56 |
| vkmc | stop leaking your passwords flaper87 | 12:57 |
| exploreshaifali | since inside bootstrap.py we are also defining "self._control.message_controller = self._storage.message_controller" we will be forced to add message_controller inside __init__of controlDriver | 12:57 |
| flaper87 | :D | 12:57 |
| * flaper87 reads backlog | 12:58 | |
| exploreshaifali | flaper87, mooooooooooorning :D | 12:58 |
| flaper87 | and also, GOOOD MORNING! | 12:58 |
| flaper87 | exploreshaifali: hey hey hey | 12:58 |
| flaper87 | exploreshaifali: I don't want to put any preasure on you but flwang is waiting for your patch | 12:58 |
| flaper87 | :P | 12:58 |
| flaper87 | hahahahah | 12:58 |
| exploreshaifali | flaper87, oh, okay, we will make it asap, sorry for being late | 12:59 |
| flaper87 | exploreshaifali: haha, you're not late, I was just messing with you | 12:59 |
| exploreshaifali | :/ | 12:59 |
| exploreshaifali | hahahahaha | 13:00 |
| vkmc | so, now that you are here flaper87 | 13:03 |
| vkmc | given that exploreshaifali was hitting too many issues with the pipeline design for the data/control plane split | 13:03 |
| vkmc | we thought about a different approach | 13:04 |
| vkmc | precisely, we though about serializing when planes are started | 13:04 |
| vkmc | and passing a reference of the dataplane to the controlplane | 13:04 |
| vkmc | that way, queuecontroller in the controlplane can access the messagecontroller in the dataplane | 13:04 |
| exploreshaifali | https://etherpad.openstack.org/p/data-plane-control-plane | 13:06 |
| vkmc | to do it, we 1. initialize datadriver 2. initialize controldriver with the datadriver reference 3. establish a reference to the controldriver in the datadriver using a private method | 13:06 |
| vkmc | so, your feedback would be super appreciated (wink wink, gummybears) | 13:08 |
| *** dynarro has quit IRC | 13:08 | |
| exploreshaifali | vkmc, we initialize datadriver with reference of controldriver | 13:09 |
| vkmc | exploreshaifali, you can do it either ways | 13:10 |
| vkmc | maybe its more advisable to init controldriver first | 13:10 |
| exploreshaifali | okay, two things to be mentioned, just to make you aware of that vkmc | 13:17 |
| vkmc | shoot | 13:17 |
| exploreshaifali | we assumed that first storage() is called and than control() will by transport() | 13:17 |
| exploreshaifali | but inside storage() there is a call to control() | 13:17 |
| vkmc | yes | 13:18 |
| exploreshaifali | https://github.com/openstack/zaqar/blob/master/zaqar/bootstrap.py#L110 | 13:18 |
| vkmc | so, to keep things simple | 13:18 |
| exploreshaifali | but that is not a big issue | 13:18 |
| vkmc | we could call control first, then storage | 13:19 |
| exploreshaifali | yea or I have made a try-except block inside control() | 13:19 |
| exploreshaifali | and inside try kept code for setting queue_controller and message_controller | 13:20 |
| exploreshaifali | that worked fined | 13:20 |
| exploreshaifali | vkmc, second thing is, while starting server I am getting error v | 13:21 |
| exploreshaifali | http://paste.openstack.org/show/186359/ | 13:21 |
| vkmc | exploreshaifali, ok... and what do you think it is? | 13:22 |
| exploreshaifali | as what is says it is because https://github.com/openstack/zaqar/blob/master/zaqar/bootstrap.py#L155 | 13:23 |
| exploreshaifali | but it also says something about MessageQueueHandler... let me try to remove it because as per the new implementation it is no more needed | 13:25 |
| exploreshaifali | get rid of messagequeuecontroller but second error is still there ---> http://paste.openstack.org/show/186369/ | 13:41 |
| vkmc | exploreshaifali, I have to be away for a while now | 13:49 |
| vkmc | exploreshaifali, try to start from a clean base and do little changes and test it gradually | 13:49 |
| vkmc | exploreshaifali, I'll be back in a while | 13:49 |
| exploreshaifali | okay :D | 13:50 |

| kragniz | cpallares: yeah, I've not spent much time in boston city, though | 15:24 |
| cpallares | kragniz: Have you gone to the MIT museum? If not I recommend going there. There's a monopedal robot there. | 15:25 |
| cpallares | kragniz: I didn't go this time, but I went last year. | 15:25 |
| cpallares | kragniz: They had kinetic art and hologram art. | 15:25 |
| cpallares | kragniz: and robots! | 15:26 |
| kragniz | that sounds very cool! I've not been there | 15:26 |

| vkmc | oh I wanna go someday, sounds great | 15:26 |

| kragniz | what robots do they have there? | 15:27 |
| kragniz | wow | 15:27 |
| cpallares | kragniz: They have this really cool monopedal robot and it jumps around. | 15:27 |
| cpallares | I mean, it has to because else it falls. | 15:27 |
| vkmc | lol | 15:27 |
| kragniz | hehe | 15:27 |
| cpallares | There's also this creepy emotions robot. | 15:27 |

| kragniz | cpallares: ah, that one | 15:38 |
| kragniz | I remember trying to make something inspired by that in lego | 15:38 |
| cpallares | kragniz: "ah THAT creepy robot" | 15:38 |
| cpallares | kragniz: Really? That's pretty cool. Did you succeed? | 15:38 |
| kragniz | I made something that could look up, down, around and flap a thing which was supposed to be a mouth | 15:39 |
| cpallares | kragniz: Like the legos that are used in the FLL? | 15:52 |
| cpallares | kragniz: Or the mindstorms one? | 15:53 |
| cpallares | kragniz: Making a robot like that with a mindstorms kit would be kind of hard. | 15:53 |
| kragniz | cpallares: yeah, but the older one which came out around 2000 (yellow brick) | 15:53 |
| kragniz | tell me about it! Those motors were terrible! | 15:54 |
| kragniz | the newer ones have servos, which would make life a lot more happier | 15:54 |
| cpallares | kragniz: I've never played with the older ones, but I just googled it and that looks horrible. | 15:54 |
| cpallares | kragniz: Why are the connectors bricks. They're going to fall. | 15:55 |
| kragniz | I loved it :( | 15:55 |
| cpallares | haha | 15:56 |
| kragniz | you could stack the connectors! | 15:56 |
| cpallares | kragniz: You can? | 15:56 |
| cpallares | That's pretty cool! | 15:56 |
| cpallares | Why did they take that away??? | 15:56 |
| kragniz | yeah, both the top and bottom have connectors | 15:56 |
| cpallares | kragniz: Lego mindstorms are some seriously cool stuff. I was reading about this high school kid who built a braille machine using one. Braille machines are like thousands of dollars and this kid built one with $300. | 15:58 |
| kragniz | that's very neat! | 15:59 |
| cpallares | Ah wait, he's in middle school. | 15:59 |
| cpallares | Which is even cooler. | 15:59 |
| kragniz | I think the best I got to was a printer | 15:59 |
| kragniz | well, plotter | 16:00 |
| cpallares | kragniz: A real one or like a 3D one? | 16:00 |
| cpallares | :P | 16:00 |
| kragniz | a real one with paper :P | 16:00 |
| cpallares | kragniz: Could you plot stuff in like a giant poster? | 16:00 |
| kragniz | I'd need more than three motors for a 3d one! | 16:00 |
