[00:15:41] <jepler> seb_kuzminsky: the setting of errno to 0 looks like it went with some unfinished work
[00:16:16] <jepler> seb_kuzminsky: in the event that a packet is not recv'd (recv returned -1 and set errno) OR that a packet is received but is the wrong size, the code should log an rtapi error message, including strerror(errno)
[00:16:39] <jepler> .. but if the return value is >= 0 but != expected, I want errno to be 0 (success)
[00:16:56] <jepler> not the left over errno of some other syscall

[01:00:32] <KGB-linuxcnc> 03Sebastian Kuzminsky 052.6-remap-bug 3e9eccd 06linuxcnc 10(10 files) tests: add a test for the remap bug Andy Pugh found * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=3e9eccd
[01:01:08] <seb_kuzminsky> jepler: ah yes, the good old "Error: Success"
[01:01:11] <seb_kuzminsky> love that one
[01:01:37] <seb_kuzminsky> the 2.6-remap-bug branch reproduces the "duplicate O-word" bug in runtestable form
[01:01:49] <seb_kuzminsky> i removed as much as i could without making the bug go away
[01:02:56] <seb_kuzminsky> if i remove the M66 in toolchange.ngc, it no longer prints that "duplicate O-word" error
[01:03:02] <seb_kuzminsky> and then the test passes
[01:04:46] <jepler> somebody mumbled that it might "have to do with queue busters", of which I think M66 are one

[14:29:44] <pcw_home> Something has gotten better! with the jepler/hm2-eth-startup branch
[14:29:45] <pcw_home> I can now start linuxcnc at 4 KHz on my home desktop (C2D 8500) without error (this barely ever worked before)
[14:29:47] <pcw_home> and... it been running at 4 KHz all night with youtube videos playing which it also did not do before
[14:29:48] <pcw_home> (This part may be related to the kernel which I updated to 4.1.3-rt3)

[14:44:59] <skunkworks> wow
[14:45:20] <skunkworks> it is always nice to have jepler touch things...
[14:45:22] -!- amiri has quit [Ping timeout: 246 seconds]
[14:45:22] <skunkworks> ;)
[14:45:54] <skunkworks> and he said each device added about 90us
[14:45:57] <skunkworks> or so
[14:47:09] <pcw_home> so 4 devices should be easy at 1 KHz on many CPUs
[14:47:39] <pcw_home> I get less per card overhead but may have a faster CPU
[14:50:57] <skunkworks> sure
[14:51:36] <pcw_home> I'll have to try the 4.1.3-rt3 kernel on the J1800
[14:51:42] <skunkworks> my heart stopped for a second when threading didn't work on robs new branch (graphing for tom) but I was in the wrong repository
[14:52:02] <skunkworks> I am running on a j1900 I think.
[14:52:56] <pcw_home> Linxcnc order up, please hold the bugs
[14:53:59] <skunkworks> and that is how rigid tapping is done - booya!
[14:54:00] <skunkworks> http://linuxcnc.org/index.php/english/forum/40-subroutines-and-ngcgui/29451-rigid-tapping-fail-advice-and-qdiscriminantq-err?start=20#61041
[14:54:20] <pcw_home> glad you answered tome with a correct plot
[14:54:59] <seb_kuzminsky> skunkworks: do you know the state of rob's feature/tangent-improvement-2.7?
[14:55:24] <seb_kuzminsky> last i heard rob wanted to document and maybe rename "kink ratio"
[14:55:40] <skunkworks> I have found some slight overages (at the most 3%) that he hopes to look at. (I think it is shipable...)
[14:56:08] <skunkworks> and yes - he needs to document/rename the kink ratio setting.
[14:56:38] <skunkworks> I can email him and see what he thinks. He was gone over the weekend.
[14:57:24] <seb_kuzminsky> ok, cc me please
