| th1a | ignas: Do you think ZEO might be an option? | 00:00 |
|---|---|---|
| ignas | ZEO? how? | 00:01 |
| * ignas is using ZEO for lyceum... | 00:01 | |
| th1a | If the agent was a separate app that used SchoolTool's ZODB. | 00:01 |
| th1a | How are you using it? | 00:01 |
| ignas | to run new UI and old UI on the same Data.fs | 00:02 |
| th1a | Ah. | 00:02 |
| ignas | a separate app might make sense | 00:02 |
| ignas | it would not be very easy to maintain, yet it would make the implementation a lot more simple | 00:02 |
| th1a | Hm... let me think about how it would actually work. | 00:03 |
| th1a | Perhaps it wouldn't, since the agent would have to send messages in response to SchoolTool events. | 00:03 |
| th1a | So you'd still be passing a message that may or may not be received. | 00:04 |
| * ignas has to go afk for 15 mins, sorry | 00:05 | |

| *** jstraw has joined #schooltool | 00:11 | |
| *** jstraw is now known as Lumiere | 00:11 | |
| ignas | th1a: that's why i think that maintaining such thing would be more difficult, you'd have so add a queue in ZODB for comunication between the external SIF process and schooltool | 00:30 |
| ignas | on the other hand you'll need something like that if you will do it with threads anyway | 00:30 |
| ignas | I'd go for external process | 00:30 |
| ignas | as that will limit communication to 1 queue and keep both things separate (a.k.a. safe from each other) | 00:31 |
| th1a | How should the agent and the main SchoolTool process communicate? | 00:31 |
| ignas | through a queue of events stored in ZODB | 00:32 |
| th1a | Oh, I see. | 00:32 |
| ignas | processed 1 by 1 by an external SIF process | 00:32 |
| th1a | The agent would wake up and look at it periodically? | 00:32 |
| ignas | yes | 00:32 |
| th1a | ok | 00:32 |
| th1a | i can wotk on that | 00:33 |
| th1a | wotk | 00:33 |
| th1a | work | 00:33 |
| ignas | schooltool would require some primitives (functions) for putting messages into that queue | 00:33 |
| ignas | and that's it ... | 00:33 |
| th1a | yep. | 00:33 |

| aelkner | Does anyone know how I can solve what seems like an inactivity timeout I'm having with ssh? | 17:52 |
| Lumiere | there's a setting you can put in your sshd.conf | 17:53 |
| aelkner | Hey Jason. I remember you now from the sprint. | 17:54 |
| aelkner | We met almost two years ago at Dave's lab. | 17:54 |
| Lumiere | yea | 17:56 |
| Lumiere | I'll be back in a little bit | 17:56 |
| Lumiere | gotta run into the ACC :) | 17:56 |
| *** Lumiere has left #schooltool | 17:56 | |
| *** wdickers has joined #schooltool | 17:59 | |
| wdickers | morning | 17:59 |
| aelkner | good moring. have you read my email? | 18:01 |
| wdickers | yes | 18:01 |
| aelkner | there's more I would like to explain. | 18:01 |
| aelkner | First, did you notice that I left two routines there that are the old way? | 18:02 |
| wdickers | one moment, I haven't had a chance to look at the files | 18:02 |
| wdickers | Alright, the makeAck and makeError? | 18:04 |
| aelkner | Right. Notice how buildElement allows us to halve the size of the code by doing two things for us? | 18:05 |
| wdickers | Yeah, and I like how you used **kw | 18:06 |
| aelkner | I love being concise :) | 18:06 |
| aelkner | So. if you run it you'll see how it builds then parses. | 18:07 |
| wdickers | The only reason I didn't want to use **kw in the first place was that it makes the calls to that method rather long | 18:07 |
| wdickers | Because you have to have key=value for each argument | 18:08 |
| aelkner | It does, but the statement to build the dict is even longer, right? | 18:08 |
| wdickers | Yeah, you're right | 18:08 |
| aelkner | So now we have the model for trnaslating to and from dict and xml, thus encapsulating lxml. | 18:09 |
| aelkner | This way we could even change our mind (which we won't) about which tree lib to use without changing any code but this routine. | 18:09 |
| wdickers | Ahhh. Nice | 18:10 |
| aelkner | That's the kind of programming practice I prefer. Keep everything in its place. | 18:10 |
| aelkner | Anyway, you could continue what I've done with other messages. | 18:10 |
| th1a | Is this in svn? | 18:10 |
| wdickers | So now we only use etree in two places in the class | 18:10 |
| wdickers | Sure | 18:11 |
| aelkner | Not yet. | 18:11 |
| aelkner | What's the command: svn commit -m "whatever"? | 18:11 |
| wdickers | So you want me to change makeAck and makeError? How will I call the methods of MessageTools? | 18:12 |
| aelkner | Will, I thought rather than pair on the same file (which we can do at times), we'd split our work. | 18:13 |
| wdickers | okay. What would you like me to work on? | 18:13 |
| aelkner | You can make routines buildAck and buildError within the class that does the same thing. | 18:13 |
| aelkner | Then you can get rid of makeAck and makeError. | 18:14 |
| aelkner | Also there's all kinds of other messages that need to be built and parsed. | 18:14 |
| aelkner | See exam.py as a guide. | 18:14 |
| aelkner | th1a: ? | 18:14 |
| wdickers | Okay. I'll have to copy the files and work on it in my directory though, I don't have permission to edit in yours | 18:14 |
| aelkner | I can fix that. | 18:15 |
| aelkner | What group are you in? | 18:15 |
| aelkner | th1a: Are you there? | 18:15 |
| wdickers | Hmm, I'm not sure. But my account is on maddog so I'm guessing I'm not public | 18:15 |
| aelkner | look in /etc/groups. | 18:16 |
| aelkner | /etc/group | 18:16 |
| aelkner | /etc/passwd | 18:16 |
| aelkner | Looking there it looks like Jeff needs to set up groups for us. | 18:17 |
| aelkner | Now it seems like we only belong to a group with our own name. | 18:18 |
| wdickers | Yeah, all I see is this | 18:18 |
| wdickers | wdickers:x:1003:1003:Will Dickerson,,,703 969 5580:/home/wdickers:/bin/bash | 18:18 |
| aelkner | Go ahead and copy and edit as you suggested. | 18:18 |
| wdickers | alright | 18:18 |
| aelkner | I'll let you know when Jeff solves our problem. | 18:18 |
| th1a | aelkner: What? | 18:18 |
| wdickers | I can go tell jeff what do to. We want a group of who exactly, just you and me? | 18:19 |
| aelkner | th1a: my question above? | 18:19 |
| aelkner | svn commit... | 18:19 |
| aelkner | Right. He's there. | 18:19 |
| aelkner | We need a group call develop that has you, me, and hoffman as members for starters. | 18:20 |
| wdickers | gotcha | 18:20 |
| aelkner | th1a: ? | 18:20 |
| aelkner | th1a: you're there, but you're not it seems. | 18:21 |
| th1a | svn commit? | 18:23 |
| aelkner | svn commit -m "message", right? | 18:23 |
| aelkner | Will, can you get Jeff to come over to your station to help me with another problem when he can? | 18:25 |
| th1a | To? | 18:26 |
| th1a | We do? | 18:26 |
| th1a | What are we trying to do? | 18:26 |
| th1a | What's the question? | 18:26 |
| aelkner | th1a: you asked me if I commited my changes. I asked you for the command. | 18:27 |
| wdickers | he made the group openzis | 18:28 |
| wdickers | I'll get him over here | 18:28 |
| aelkner | When he gets there, please have him add the following to /etc/ssh/sshd/config: | 18:29 |
| aelkner | ClientAliveInterval 300 | 18:29 |
| aelkner | Tell him its to stop my ssh client from disconnecting if I'm not active constantly. | 18:30 |
| *** th1a_ has joined #schooltool | 18:30 | |
| wdickers | he got the message | 18:30 |
| aelkner | thanks. | 18:30 |
| aelkner | th1a_? what's that? | 18:30 |
| th1a_ | Hm... lagging on my desktop so I switched to my laptop. | 18:30 |
| th1a_ | Not getting good reception on the desktop. | 18:31 |
| aelkner | I see. | 18:31 |
| aelkner | svn commit -m "message"? | 18:31 |
| *** th1a_ is now known as th1a|X60s | 18:31 | |
| th1a|X60s | To where? | 18:31 |
| aelkner | Remember I did the svn co to maddog and am editing there. | 18:31 |
| aelkner | Will's there, too. | 18:31 |
| aelkner | Tomorrow at 10, you and I will be there. | 18:32 |
| th1a|X60s | Yes... but I don't want you to cmmit to the tinyzis trunk. | 18:32 |
| aelkner | Well, this is what I need you to explain to me. How to do updates as a rule. | 18:33 |
| th1a|X60s | We need to make a separate project, right? | 18:33 |
| wdickers | elkner can't find the file. There's only /etc/ssh/sshd_config he's asking you to look to make sure | 18:34 |
| th1a|X60s | What is this agent called? | 18:34 |
| aelkner | Will, that's the one. I made a typo. | 18:34 |
| aelkner | Also, tell him to do this when he's done editing: | 18:34 |
| aelkner | /sbin/service sshd reload | 18:34 |
| aelkner | th1a: we haven't created an agent yet. We plan on creating multiple agents to test our framework of push and pull. | 18:35 |
| aelkner | th1a: is your question geered to nameing a branch? | 18:36 |
| th1a | Where are you committing to? | 18:36 |
| aelkner | I dunno. I thought you would be telling me these things. | 18:37 |
| aelkner | So far I added files to the trunk. I could put htem elsewhere if you so desire. | 18:37 |
| aelkner | I haven't commited anything yet. | 18:37 |
| th1a|X60s | That second "Where are you committing to?" took about five minutes to make it to you. | 18:39 |
| wdickers | he restarted ssh, is that what you needed? | 18:39 |
| th1a|X60s | That's why it is out of context. | 18:39 |
| aelkner | I understand, networking problems... | 18:39 |
| th1a|X60s | Anyhow, this is a separate project. | 18:39 |
| wdickers | Alright, I'm out of time. I'll finish the makeAck and makeError by tomorrow | 18:39 |
| th1a|X60s | So it needs a name. | 18:39 |
| aelkner | buildAck, right? | 18:39 |
| aelkner | that was for Will. | 18:40 |
| aelkner | th1a: why not call it agents? | 18:40 |
| aelkner | or agentBase? | 18:40 |
| wdickers | ah, I'll change the names | 18:41 |
| th1a|X60s | PyAgent? | 18:41 |
| aelkner | Will, did Jeff run the sshd reload? | 18:41 |
| *** wdickers has quit IRC | 18:41 | |
| aelkner | Ok, Tom, Will is gone so my messages are for you bydefault. | 18:41 |
| aelkner | PyAgent, why not? | 18:41 |
| aelkner | Assume I'm a novice with svn, and please explain branches and what I need to do to use them. | 18:42 |
| th1a|X60s | This isn't a branch, because it is a different project. | 18:42 |
| aelkner | Why a different project when the source can live in the same directory? | 18:43 |
| aelkner | Remember code sharing? | 18:43 |
| th1a|X60s | Well, ultimately there will need to be three packages. | 18:44 |
| th1a|X60s | The shared libraries, the ZIS and the Agent libraries. | 18:44 |
| aelkner | Ok, so we do that later as we agreed. | 18:45 |
| aelkner | For now you want a new peoject, right? | 18:45 |
| th1a|X60s | Yes. | 18:45 |
| th1a|X60s | Give me a minute to create it. | 18:45 |
