[00:11:28] <CIA-95> EMC: 03andypugh 07v2.5_branch * rdbc34400025a 10/ (6 files in 3 dirs): Add support for the Mesa Hostmot2 Resolver interface.
[00:13:52] <JT-Shop> did you get Les's message comp to work?
[00:14:06] <andypugh> Yes. You?
[00:14:23] <andypugh> I would have pushed it, except I am not sure about the license
[00:14:31] -!- cpresser has quit [Ping timeout: 260 seconds]
[00:16:38] <micges> andypugh: iirc emc2 follows kernel licensing
[00:16:50] <andypugh> I don't know what that mean
[00:16:52] <andypugh> s
[00:18:18] <micges> it means that comp modules can't be lgpl but pure c hal modules can
[00:18:44] <andypugh> OK. So, we can't use that comp then.
[00:19:04] -!- Loetmichel has quit [Ping timeout: 240 seconds]
[00:19:41] <micges> iirc that was what SWPadnos told me
[00:20:40] <micges> better wait for someone with some more knowlege
[00:25:41] <JT-Shop> I never could get it to work
[00:25:56] <JT-Shop> my internet connection sucks since yesterday
[00:29:26] -!- robh__ has quit [Ping timeout: 276 seconds]
[00:33:14] <JT-Shop> finally got enough packages installed on the liniux computer up here to start building the pl docs :/
[00:36:52] <andypugh> JT-Shop: You couldn't get the message comp to work?
[00:44:26] <JT-Shop> andypugh: no it gave me some errors
[00:44:42] <andypugh> What errors?
[00:45:06] <andypugh> It seems to be working for me here, but the version I am playing with had some attention from cradek
[00:45:23] <andypugh> loadrt message names="hello,world" messages="you say hello,and I say goodbye"
[00:45:27] <JT-Shop> micges: I think I got all the typos in file name sorted out and the Polish docs seem to be building now :)
[00:45:53] <JT-Shop> I don't remember but it would not make, and I was using the original one from Les who uses 8.04
[00:46:10] <micges> JT-Shop: yay
[00:46:23] <andypugh> Well, it definitely makes now.
[00:47:27] <andypugh> Right, I need to sleep.
[00:48:00] <micges> me too

[00:52:47] <JT-Shop> I've been conversing with Les do you want me to see if he will release a GPL version?

[02:31:53] <jepler> First, a factual statement: The terms of the LGPL2 are compatible with the GPL2, but the LGPL2 *string* for MODULE_LICENSE (the thing that license "..." compiles into) doesn't treat the string LGPL specially (it does treat GPL specially).
[02:33:27] <jepler> next, my opinion: I would rather see any component shipped with emc2 using the GPL license, and I'd also prefer that the code explicitly enable the "or later versions" clause
[02:34:13] <jepler> if the code is not compatible with the GPL at all, then I would be very reluctant to the source in emc's git or compile and ship the result to users.
[02:35:24] <jepler> If the concern is that you aren't 100% sure what the license is, then yes you need to continue the dialog with the author until he sends you a version that is unambiguous in its license.
[02:36:50] <jepler> the LGPL2 section 3 explains that you may opt to use the GPL for any code that comes to you under LGPL, so if the question is GPL or LGPL then we can mark it GPL everywhere and the question is put to rest

[21:27:20] <andypugh> Can I have some advice on whether a kernel "taint" from an LGPL module matters?
[21:27:45] <cradek> what do you mean?
[21:28:10] <andypugh> That's part of the question
[21:28:18] <cradek> uh-oh, metaquestion
[21:29:27] <andypugh> Les's "message" component:
[21:29:28] <andypugh> [ 1681.777986] message: module license 'LGPL' taints kernel.
[21:29:49] <cradek> I thought he already changed it to gpl 2 or later
[21:30:05] <andypugh> He said I could change it.
[21:30:25] <andypugh> I was just wondering if it was necessary?
[21:30:46] <cradek> if it's necessary for what?
[21:30:58] <andypugh> In either case it seems to work and I am about to push it, unless you can recall any problems with it?
[21:31:14] <andypugh> If it is necessary to change the license from what the author typed.
[21:31:47] <cradek> did you get my changes incorporated already?
[21:32:22] <andypugh> I started with your pastebin, then added modparam documentation,
[21:32:31] <cradek> jepler gave us some facts and opinions about the license - I defer to his judgement
[21:32:50] <andypugh> That is actually all I have done, other than some testing, and a check that the string is valid before printing it.
[21:33:29] <cradek> I wish an updated version would come from the author, but it appears to be just fine to change the string, since (1) the author says it's fine, and (2) apparently it would be fine even if the author didn't say that
[21:34:18] <andypugh> I guess as it was LGPL, and we changed it, we get to choose the license.
[21:34:44] <andypugh> (I didn't see anything from Jepler)
[21:36:25] <cradek> it was in this channel earlier

[21:49:45] <andypugh> Should I append a \n to the messages?
[21:55:13] <cradek> have you tested with and without? in dmesg it sure looked like \n was needed. I wonder, but did not test to see, which way it shows up correctly in AXIS
[21:55:30] <andypugh> Just about to test that

[23:13:58] <mhaberler> how does currently executed line information trickle back from motion into a gui?
[23:15:24] <mhaberler> through emcstat?
[23:16:07] <mhaberler> oh, I see: self.emcstat.motion_line
[23:16:31] <andypugh> I nearly knew the answer to that
[23:21:00] <mhaberler> am I overlooking something or does at least axis only highlight lines in the main program, not in subs?
[23:25:09] <mhaberler> looks like touchy doesnt either
[23:26:36] <mhaberler> seems the motionLine is lacking context - ngc file, MDI string, python file
[23:27:44] <andypugh> I have a feeling it only highlights motion moves too.
[23:27:54] <mhaberler> thats fon
[23:28:15] <mhaberler> fine, I'd just be curious where they *really* come from
[23:28:42] <mhaberler> they guis have no way of finding out
[23:29:58] <mhaberler> interp_list.set_line_number(line_number); in task is as far as much detail is passed
[23:30:43] <andypugh> It would be nice to have more context, so you can pick it back up after a pause.
[23:31:21] <mhaberler> pick?
[23:33:37] <mhaberler> when debugging a remapped code you're pretty much in the dark
[23:34:13] <mhaberler> 'it's an M6' ! sure, all 100 lines of it...
[23:36:10] <mhaberler> I guess we need a source context id additional tp line number; context = type (MDI,NGC,Python) plus filename/string
[23:37:39] <mhaberler> managed by interp, cleared by task, accessible to ui
[23:40:09] <andypugh> Indeed. I expect it by morning :-)
[23:41:05] <andypugh> Filename alone might do, with null=MDI?
[23:41:22] <mhaberler> well, the issue is beyond cosmetic - some of the MDI vs file execution prblems stem from that
[23:43:32] <andypugh> Anyway, goodnight.
