[2016-02-29T22:13:52+0100] <orrc> slave -> agent is done [2016-02-29T22:14:00+0100] <rtyler> right [2016-02-29T22:14:04+0100] <orrc> so now we have "agent" and "node" [2016-02-29T22:14:42+0100] <rtyler> ah right, you and I already talked about this I see [2016-02-29T22:14:47+0100] • rtyler: cheers [2016-02-29T22:15:16+0100] <orrc> yeah. so because of technical reasons, users get to see a mixture of terms, as I understand it [2016-02-29T22:34:10+0100] <batmat> orrc: nodes = any machine in a Jenkins cluster, agent aka slave [2016-02-29T22:34:23+0100] <batmat> orrc: was the discussion on the gov meeting for the rename [2016-02-29T22:34:31+0100] <batmat> and why node wasn't selected [2016-02-29T22:34:39+0100] <orrc> batmat: you misunderstand :) [2016-02-29T22:34:58+0100] <orrc> batmat: I'd like to kill the word "node" entirely from Jenkins — node is already used [2016-02-29T22:36:11+0100] <batmat> orrc: well, why not merge into one word, I'm not sure, but not sure agent is better to keep than node :) [2016-02-29T22:37:20+0100] <rtyler> batmat: did you see orrc's comment on the ticket above from last time we discussed this? [2016-02-29T22:38:30+0100] <orrc> batmat: https://i.imgur.com/KCgg1in.png [2016-02-29T22:38:43+0100] <orrc> "Slave foo" / "Mark this node offline" [2016-02-29T22:39:00+0100] <orrc> also nice: "This *node* is offline because the *slave* agent failed to launch" [2016-02-29T22:39:10+0100] • orrc: wonders how "slave agent" got translated in "slave" -> "agent" [2016-02-29T22:40:11+0100] <batmat> orrc: yeah right. IMO we should indeed review that screen in the 2.0 alpha (or the branch itself, and `git grep`ing that string) [2016-02-29T22:41:01+0100] <orrc> batmat: I'd rather "node" wasn't used anyway — we've chosen "agent" to mean a machine where builds are happening, so it would be nice to use that *everywhere* [2016-02-29T22:41:08+0100] <orrc> s/anyway/anywhere [2016-02-29T22:46:29+0100] <orrc> with Jenkins 2.0: https://i.imgur.com/rkVktB8.png … [2016-02-29T22:51:23+0100] <@danielbeck> orrc node includes master, agent does not. That was my understanding. Otherwise we need more terminology … [2016-02-29T22:54:18+0100] <orrc> danielbeck: yeah, that's clear. technically everything is a node, but there's no reason to expose this terminology to users. if master has executors (as it does by default) that's an agent that can run builds for me. if I attach another agent, that's another agent that can run builds for me [2016-02-29T22:54:47+0100] <@danielbeck> IOW it's just redundant and you now have "agents other than master" [2016-02-29T22:55:53+0100] <@danielbeck> rtyler I don't think it's possible [2016-02-29T22:57:00+0100] <@danielbeck> orrc AFAIK the intention was to have a drop in replacement for 'slave', so having 'agent' mean the same as 'node' would change its meaning and lead to the problem that you have no term for what used to be called slave. … [2016-02-29T23:01:58+0100] <orrc> danielbeck: what type of problems are you thinking of that would be caused by "node" being called "agent"? [2016-02-29T23:02:42+0100] <@danielbeck> You mean besides confusion and redundancy, and the fact that we don't have a new term for what used to be called Slave? [2016-02-29T23:04:14+0100] <@danielbeck> Master is a node. A slave is a node. Master is not a slave. So we need to be very clear about which term we're replacing with another one, and that term is 'slave'. [2016-02-29T23:04:55+0100] <@danielbeck> Otherwise you'll just have 'agent' mean 'node', and people will continue using 'slave' because there's no alternative, and we won't have accomplished anything. [2016-02-29T23:05:04+0100] <abayer> Yeah, that makes sense to me. [2016-02-29T23:06:22+0100] <abayer> If we'd architected things such that the executors on the master were also a "slave" rather than within the existing master JVM, then "agent" as all-purpose "box with executors" would make sense, but given the distinction between master executors and non-master executors, keeping separate terminology makes sene. [2016-02-29T23:06:23+0100] <abayer> sense [2016-02-29T23:06:39+0100] <orrc> I don't see why people would keep using "slave" because the job-executing part of master was renamed to "agent" [2016-02-29T23:07:43+0100] <orrc> master does coordination, but also (optionally) runs as an agent for me, executing builds. same as an external agent [2016-02-29T23:08:02+0100] <orrc> but yeah, I kinda see what you're saying abayer [2016-02-29T23:08:13+0100] <orrc> and there was talk of splitting this up at the 2.0 summit :) … [2016-02-29T23:08:46+0100] <abayer> I'm thinking about it like Puppet masters and agents - you run the Puppet agent on the Puppet master too, but it's a separate process, etc... … [2016-02-29T23:09:40+0100] <orrc> abayer: right. but why should end users care about this technical distinction within Jenkins core? [2016-02-29T23:11:10+0100] <@danielbeck> orrc Are you offering to write the user and dev docs that explain this mess? Because it's pretty straightforward with node/master/agent. Agent/master/???, not so much. [2016-02-29T23:11:38+0100] <rtyler> is anybody at all willing to write any user and dev docs that explain any messes? :( [2016-02-29T23:11:47+0100] • rtyler: quietly agents away over jenkins docs [2016-02-29T23:12:47+0100] <orrc> danielbeck: my argument that it's not straightforward. and I genuinely don't see why having one thing called "agent", which master can also be, is a mess [2016-02-29T23:13:24+0100] <orrc> and yeah, the idea was to then ensure that as much documentation as possible uses the one term. rather than "node", "agent", "slave", "build machine", "worker" and whatever else is out there Add Comment   This message was sent by Atlassian JIRA (v6.4.2#64017-sha1:e244265) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
