[00:11:56] <kwallace> I copied the threading code in interp_convert.cc in Interp::convert_threading_cycle and Pythonized it to get http://www.wallacecompany.com/tmp/pass_count.py .
[00:13:31] <kwallace> The printout shows the first two passes don't cut anything, then the next doesn't take a full cut. Would it be a bad thing to try to optimize this?

[00:24:11] <kwallace> Oops, I'm wrong the first two cuts are at the first depth of cut.
[00:27:41] -!- racycle has quit [Quit: racycle]
[00:29:22] <kwallace> Another oops, I had to change the increment code because Python doesn't like ++tpass. I should have put the increment two lines up. So the code is perfect.

[15:14:15] <dgarr> for consideration, patch to help gremlin beginner: http://www.panix.com/~dgarrett/stuff/0001-gremlin-run-give-usage-message-for-startup-errors.patch
[15:14:40] <dgarr> (v2.5_branch)
[15:19:36] <seb_kuzminsky> dgarr: looks good to me (i only read the code, didnt test it)
[15:19:41] -!- cherry_l1n has quit [Ping timeout: 255 seconds]
[15:22:49] <cradek> dgarr: I agree it looks good. did you test it thoroughly?
[15:23:46] <cradek> dgarr: I also got your other patch, but I got stalled on it because you requested it go into 2.5 but it's a large change that does not fix a bug. is master ok?
[15:23:56] <dgarr> is there such thing as thoroughly? itested with valid ini arg, with invalid ini arg, with no iniarg
[15:24:28] <cradek> that's thoroughly in my book (try every code path)
[15:25:12] <dgarr> i would much prefer v2.5_branch as i think master is too far away, maybe others would like to test or comment:
[15:25:16] <dgarr> http://www.panix.com/~dgarrett/stuff/names_in_halfiles.patch
[15:25:34] <dgarr> of course, it's up to you:)
[15:25:44] <cradek> ok, I'm open to other input
[15:26:32] <cradek> I think I'm starting to get spooked by the massive number of changes in 2.5 without a release. "it's not you, it's me" haha
[15:27:47] -!- plushy has quit [Ping timeout: 256 seconds]
[15:28:53] <cradek> it does improve those files
[15:28:54] <seb_kuzminsky> cradek: i'm getting closer and closer to pushing the substantial part of my toolno/pocketno fix
[15:29:05] <cradek> seb_kuzminsky: yay! tell me if I can help.
[15:29:16] <seb_kuzminsky> i'll have the t0 tests we talked about ready maybe tonight or tomorrow night
[15:29:33] <cradek> another weekend coming up... would be great if we could finish up and release.
[15:30:06] <KGB-linuxcnc> 03seb 05t0-test d2ca7fd 06emc2 10tests/t0/ 10(21 files in 5 dirs) * add tests for t0 handling

[15:30:09] <seb_kuzminsky> well, since you offered to help...
[15:30:15] <KGB-linuxcnc> 03seb 05t0-test d5143f6 06emc2 10docs/src/gcode/other-code.txt * docs: update T-word documentation to match reality
[15:30:22] <KGB-linuxcnc> 03seb 05t0-test 8a483e2 06emc2 10docs/src/gcode/tool_compensation.txt * docs: add an anchor for the Tool Changers section
[15:30:28] <KGB-linuxcnc> 03seb 05t0-test ccc0f03 06emc2 10docs/src/gcode/gcode.txt * docs: clean up the G43 section a bit
[15:30:34] <KGB-linuxcnc> 03seb 05t0-test ca7ade0 06emc2 10docs/src/gcode/gcode.txt * docs: note funny behavior of G41/G42 D0
[15:30:37] <seb_kuzminsky> if you want to review the t0-test branch i just pushed, that would help (it's pretty straightforward)
[15:30:45] <cradek> ok
[15:31:03] <seb_kuzminsky> i know the last commit needs a little work, but i feel pretty good about the others
[15:31:50] <seb_kuzminsky> it sets up linuxcnc in sim mode (not sai) and runs a bunch of g10/m6/g43 mdi through it, and uses a named subroutine to write numbered parameters to a file, and verifies that the output is what's expected
[15:31:57] <JT-Shop> I tried for weeks to get gremlin-run.py to work and finally gave up on that
[15:31:58] <cradek> last one, meaning the doc change?
[15:32:07] <seb_kuzminsky> last one meaning the tip of the branch
[15:32:16] <seb_kuzminsky> the last half dozen commits or so are all docs
[15:33:05] <cradek> D0 is cringeworthy, isn't it
[15:33:15] <seb_kuzminsky> it runs this test in three configurations: nonrandom-tc, random-tc with t0 in the tool file, and random-tc with *no* t0 in the tool file
[15:33:19] <seb_kuzminsky> they all behave diffently ;-)
[15:33:36] <seb_kuzminsky> g41/g42 d0 is cringely, and g43 g0
[15:33:37] <cradek> I/we should've never allowed T0 for random, but that ship has sailed and sunk long ago
[15:34:02] <seb_kuzminsky> g10 p0 is not allowed, so t0 is really not a regular tool, even on random
[15:34:23] <seb_kuzminsky> i think the goal behind t0 on random is worthy (to track an empty pocket)
[15:34:29] <cradek> you mean g10 l1* p0?
[15:34:39] <seb_kuzminsky> yes, that's not allowed because p0 is rejected
[15:34:44] <cradek> I think g10 l2* p0 has special meaning unrelated to tools
[15:34:47] <cradek> right ok
[15:35:15] <seb_kuzminsky> yes, g10 l2 and g10 l20 both accept p0, but p means something different if the first digit of the L-number is 2 ;-)
[15:35:48] <seb_kuzminsky> i didnt mess with G10 L2/L20 at all, only L1* since that's the only G10 that cares about tools
[15:35:58] <seb_kuzminsky> bbl, work :-/
[15:36:06] <cradek> "don't set length or diameter on your empty pocket" seems sane enough but G10, H, D, all have to get weird

[15:52:45] <kwallace> Just an empty spouting of opinion, but T0 , P0 should be just another tool or pocket identification. The state or property should be maintained through another means.
[15:52:49] <kwallace> More documentation or hand holding code in gremlin-run would be a good thing, but I'm not sure anyone but a very few people would use it.
[15:54:09] <cradek> kwallace: I agree with you, except there is a historical problem. G42D0 has always been documented to mean the same as G40, and G43H0 has always been documented to mean the same thing as G49.

[16:02:11] <kwallace1> A knee jerk reaction might be, let's just start over with all new code. I also got that feeling with finding that OpenGL in LinuxCNC is 2.1 and the current version is 4.3 .
[16:03:26] <cradek> that knee-jerk has put companies out of business and destroyed open source projects
[16:04:02] <cradek> if you stop having a product while you rewrite, you immediately become irrelevant
[16:04:46] <cradek> and whether or not you do a full rewrite, if you break everyone's existing gcode, you've still got the same problem

[18:03:03] <jthornton> touch screen?
[18:13:20] <cradek> seb_kuzminsky: some other tests have sed 's/-0\.0000/0.0000/g'. you could add that to shared-checkresult and fix your -expected files to not have the minuses.

[18:28:04] <kwallace1> jthornton , No touch on this one, it's for playing with code. It's nice to be able to have two files side by side. :)

[18:30:27] <jthornton> yes, I even had a dual monitor setup once but it was not ideal...
[18:31:08] <seb_kuzminsky> giant screens are super nice for developing

[18:32:41] <seb_kuzminsky> heh, i was just about to push a similar commit
[18:32:55] <cradek> sorry, no response made me think you were still away
[18:33:04] <cradek> duplicating work sucks
[18:33:31] <seb_kuzminsky> thanks for fixing it, i should have said something
[18:34:07] <seb_kuzminsky> i don't think the redirect & mv stuff is needed, if you give sed a filename it's default behavior is to modify the file in place
[18:34:17] <seb_kuzminsky> i think
[18:35:12] <cradek> I don't think that is right
[18:35:16] <cradek> (without looking...)
[18:36:16] <cradek> yeah sed doesn't do that
[18:36:53] <seb_kuzminsky> you're right, i'm wrong
[18:37:18] <seb_kuzminsky> oh, i'm thinking of "sed --in-place"
[18:37:46] <cradek> oh hey, I didn't know about that. I thought only perl had it.
[18:38:06] <seb_kuzminsky> you should write an awk script to replace all your perl scripts with sed scripts
[18:38:54] <cradek> an ooooold bsd sed doesn't have it
[18:38:58] <cradek> it must be "new"
[18:39:41] <cradek> I've never voluntarily written a line of perl. always under duress.

[18:40:00] <seb_kuzminsky> i used to love perl, back when i had long hair and didnt know any better
[18:42:16] <skunkworks> with stella - I have not gotten a hair cut in months.. Shirley calls me fuzzy head
[18:42:48] <skunkworks> I can fling my hair around now.. haven't done that since high school
[18:42:50] <cradek> I need one again - I'm probably up near 1/2"
[18:43:11] <skunkworks> (my hair grows fast for some reason... figure it is the grey)
[18:43:24] <skunkworks> gray?
[18:43:36] <cradek> either spelling is correct

[18:45:34] <seb_kuzminsky> possibly the best $20 i've ever spent
[18:45:44] <cradek> yeah I finally bought a good one too. the crappy ones couldn't handle my beard.
[18:45:47] <seb_kuzminsky> (well there was that time in las vegas...)
[18:45:56] <cradek> I don't know why people think those things should run on batteries
[18:46:04] <seb_kuzminsky> we can't none of us handle your beard, cradek

[19:05:43] <zultron> skunkworks, I'm trying to gather all your pastebins together.
[19:05:57] <zultron> In the meantime, can you run sudo xeno-regression-test -l "/usr/lib/xenomai/testsuite/dohell -m /tmp 1000" -t 2
[19:06:04] <skunkworks> sure
[19:06:39] <zultron> ( skunkworks: Adjust the 1000 to long enough that the latency spike is observed)
[19:06:47] <zultron> (in seconds)
[19:07:16] <skunkworks> ok
[19:07:55] <zultron> Just to confirm, can you run 'sudo smictrl' and make sure the output ends with an even digit?
[19:08:53] <skunkworks> oh - I don't think I set that.. Let me do that too
[19:08:58] <skunkworks> (been re-booted
[19:09:13] <kwallace1> I find I often have Glade and gEdit open on the same file. gEdit allows me to tweak code when Glade doesn't seem to understand what I want. The problem is that I have to be careful when and which program I save from. Does Glade have a source view/edit feature that I missed?
[19:12:38] <zultron> skunkworks, here're the pastebins I have: dmesg, http://pastebin.ca/2311009 regr tests, heavy, http://pastebin.ca/2311483 smictrl output http://pastebin.ca/2311258
[19:12:50] <zultron> Can you confirm those are current?
[19:16:18] <skunkworks> Let me do a bunch of current one...
[19:16:31] <skunkworks> I am running the test for 30 minuts
[19:17:06] <zultron> Additional facts to confirm: soundcard off, uh, anything else?

[19:21:12] <skunkworks> zultron, do you see the end of the second pastbin? (did this while running test)
[19:21:18] <skunkworks> (dmesg)
[19:22:22] <cmorley> kwallace1: No. You just have to be careful. GLADE should tell you it;
[19:22:26] <zultron> The FPU message is ok.
[19:22:59] <zultron> I've seen the watchdog message before, but haven't had problems and didn't ask the Xeno guys.
[19:23:08] <cmorley> kwallace: tell you it's detected a change but i wouldn't trust it :)

[19:23:19] <skunkworks> heh
[19:25:19] <kwallace1> cmorley , I got the message but I wasn't smart about dealing with it. I should have saved to a different file, then Meld'ed.
[19:25:28] <zultron> skunkworks, I still see that the Intel sound card module is loaded. Can you rmmod it?
[19:26:12] <skunkworks> oh - sure. odd - When this test is done - I will double check the bios again. If it is disabled - I will rmmod it..
[19:26:36] <cmorley> kwallace: don't feel bad I've done it a few times too :) GLADE editor is good and bad
[19:29:19] <zultron> Anyone know if Schooner hangs out here, and what his nick is?
[19:30:28] <mhaberler> real first name mick; IRC nick - dunno
[19:31:40] <zultron> Thx. He sent an email saying he's testing the packages. Hoped to get him on a more interactive medium. :)
[19:33:18] <skunkworks> zultron, how do I rmmod it?
[19:33:26] <skunkworks> (it says it is disabled in the bios)
[19:34:25] <zultron> Well, we have to figure out which module. Pastebin 'sudo lspci -v' maybe?

[19:40:24] <skunkworks> I don't see it there....
[19:41:07] <zultron> Me neither.
[19:41:33] <zultron> How come those lines in dmesg? Hrm.
[19:41:43] <skunkworks> so - it shows in dmesg but not actually installing a driver?
[19:43:58] <zultron> Maybe I need another eyeball. I'm looking at line 765: http://pastebin.ca/2311009
[19:45:31] <zultron> the 00:1b.0 seen in dmesg is conspicuously missing in the lspci output.
[19:45:55] <skunkworks> zultron, this is the latest dmesg http://pastebin.ca/2311557
[19:46:51] <zultron> Ah ha, I had the wrong link, thanks!
[19:47:08] <zultron> Great, no sound card.
[19:47:29] <skunkworks> oh good - I think you pointed it out and I disabled it in the bios a few days ago.
[19:47:37] <skunkworks> Ok - running the test now..
[19:48:03] <zultron> Sorry 'bout that.
[19:48:32] <zultron> And output of 'sudo smictrl' looks something like 00002002?
[19:50:05] <zultron> skunkworks, One more thing, after the tests, if you capture the latency spike, please pastebin one more dmesg if there are any additional messages.

[19:52:37] <zultron> Great!
[19:54:38] <skunkworks> Stupid question - How do I know if there is a latency spike?
[20:00:16] <zultron> I just mean if you see a bunch of latencies under 25us, then suddenly a jump to 100us.

[21:12:13] <zultron> Did you say you saw 100+us latencies on this board?
[21:12:35] <zultron> skunkworks, &
[21:12:47] <skunkworks> huh - ther are no overruns...
[21:13:07] <skunkworks> yes - I am running the linuxcnc latency-test right now to see..
[21:14:49] <skunkworks> see if one shows up - didn't seem to take long with the linuxcnc latency test
[21:16:21] <zultron> Alright. If you get overruns, maybe you could fire off the same xeno-regression-test but with $((3600*24)) seconds and see if we can catch it in the act tomorrow.

[22:49:40] <JT-Shop> lol
[22:50:01] <JT-Shop> the links are much better in the html now
[22:50:08] <seb_kuzminsky> i get all the manpages listed in one column here: http://www.linuxcnc.org/docs/2.5/html/
[22:50:21] <seb_kuzminsky> that's with chrome

[22:50:53] <JT-Shop> yep, last time I looked they were in floating columns
[22:51:01] <JT-Shop> perhaps a week a go
[22:51:25] <JT-Shop> I just checked opera too
