[00:00:01] <Tom_itx> i'm debugging my control atm then i plan to look at it even though i don't have a tool changer
[00:00:13] <andypugh> The sample config uses a G-code sub. I wrote the “hardware” so that it looks like a real machine, so in theory a Classic Ladder toolchanger could be added to the same config as a separate demo.

[00:06:47] <Tom_itx> andypugh, on a RS422 board ie 7i47 do you know if i need the terminator resistors enabled or disabled... i'm using them as IO with a resistor divider on the - side

[00:08:09] <andypugh> Tom_itx: I am afraid I don’t know, I haven’t used one. PCW should be able to be definitive.
[00:08:32] <Tom_itx> yeah, he's kinda busy..
[00:09:18] <Tom_itx> i'm thinking one of the txrx chips may be bad. i'm getting 1.8v on the - side and 1.73v on the + side with nothing connected
[00:09:36] <Tom_itx> and erratic behavior on the io
[00:09:47] <andypugh> I would try it both ways. If neither work, or both work, then it’s inconclusive, otherwise you have an answer.

[00:10:07] <Tom_itx> lotsa noise
[00:11:09] <Tom_itx> i was thinking if you wanted to use them as IO you disabled the terminating resistor
[00:11:13] <Tom_itx> which is what i did
[00:11:43] <Tom_itx> the other io work, just these: 5 7 9 11 are acting strange

[03:12:26] <seb_kuzminsky> i think the tp in 2.7 is much better than the one in 2.6: better performance, but also better correctness. do you agree, skunkworks?
[03:15:05] <seb_kuzminsky> mozmck: wanna talk about release procedures?
[03:15:39] <seb_kuzminsky> i've tried to capture some of it here:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ReleaseCheckList
[03:15:50] -!- norias has quit [Ping timeout: 244 seconds]
[03:15:54] <seb_kuzminsky> a few days ago i created a local branch called 2.6.9-pre, from origin/2.6
[03:16:05] <seb_kuzminsky> i updated debian/changelog and the VERSION file
[03:16:33] <seb_kuzminsky> in the changelog i ran "git log --oneline v2.6.8..", to get the list of commits (just the first line of the commit message) since 2.6.8
[03:16:52] <seb_kuzminsky> i went down the list while looking at the full log using "gitk v2.6.8.." in another window
[03:17:28] <seb_kuzminsky> i removed the stuff that users don't care about (test improvements and other commits that don't impact anyone)
[03:18:14] <seb_kuzminsky> i sorted the remained with "more user-visible" stuff at the top and "less user-visible" stuff at the bottom
[03:18:20] <mozmck> Hi seb_kuzminsky, I can just a little here, I'm about to retire for the night.
[03:18:28] <seb_kuzminsky> yeah me too
[03:18:44] <seb_kuzminsky> i committed that change on the 2.6.9-pre branch and left it
[03:19:16] <mozmck> Ok, that makes sense
[03:19:29] <seb_kuzminsky> now i can rebase it onto 2.6 and then update the changelog with something like "git log --oneline 2.6.9-pre@{1}.." to pick up the new commits
[03:19:46] <seb_kuzminsky> this is just how i do it, there's lots of possibilities
[03:20:07] <seb_kuzminsky> when it's time for the real release, do a final update, tag (as per the RelaseCheckList wiki page), and push
[03:20:25] <mozmck> so what are you rebasing onto 2.6?
[03:20:32] <seb_kuzminsky> the buildbot will build & test & make debs, and put them im the special release deb archive
[03:20:38] <seb_kuzminsky> i rebase the 2.6.9-pre branch
[03:21:06] <mozmck> and that just has the changelog changes? or everything since 2.6.8?
[03:21:09] <seb_kuzminsky> the local one i created up at the top of my monologue
[03:21:19] <seb_kuzminsky> yeap:
[03:22:33] <seb_kuzminsky> this is the only commit in 2.6.9-pre:
[03:22:35] <seb_kuzminsky> http://paste.ubuntu.com/12053186/
[03:22:50] -!- patrickarlt has quit [Ping timeout: 272 seconds]
[03:23:10] <seb_kuzminsky> and i'm careful not to push it, so as not to confuse the buildbot
[03:23:43] <mozmck> ok. so do you have to do something to the buildbot when you do push it?
[03:24:00] <seb_kuzminsky> nothing to the buildbot, but you have to massage the branch a bit
[03:24:38] <seb_kuzminsky> so when the "2.6" branch is actually ready to release, i'll rebase the branch called 2.6.9-pre onto origin/2.6, then update the changelog one final time (and "commit --amend")
[03:24:54] <seb_kuzminsky> now 2.6.9-pre has one commit more than origin/2.6, which makes the changelog and VERSION just the way they should be
[03:25:15] <seb_kuzminsky> then i check out 2.6 and "git merge --ff-only 2.6.9-pre" to move my local 2.6 up to that point
[03:25:24] <seb_kuzminsky> tag it as described in ReleaseCheckLis
[03:25:25] -!- jthornton has quit [Ping timeout: 245 seconds]
[03:25:28] <mozmck> I see.
[03:25:33] -!- JT-Shop has quit [Ping timeout: 250 seconds]
[03:25:37] <seb_kuzminsky> then "git push 2.6 v2.6.9"
[03:25:42] <seb_kuzminsky> and the buildbot will do its thing
[03:25:51] <mozmck> that pushes the tag?
[03:25:58] <seb_kuzminsky> yeah, the tag and the branch
[03:26:01] <mozmck> ok
[03:26:03] <seb_kuzminsky> (the 2.6 branch)
[03:26:12] <seb_kuzminsky> then you watch the buildbot to make sure all's well
[03:26:27] <mozmck> yeah
[03:26:33] <seb_kuzminsky> then it's moving debian packages around, which is another bit of work with special tools & stuff
[03:26:38] <seb_kuzminsky> i'll show you that another night :-)

[03:27:18] <mozmck> ok :) I better head to bed now - I'll look at that stuff maybe tomorrow and ask if I have questions.
[03:27:27] <seb_kuzminsky> cool
[03:27:30] <seb_kuzminsky> good night
[03:27:35] <mozmck> Sounds pretty straightforward though so far.
[03:27:47] <seb_kuzminsky> yeah, just a bunch of git jiu jitsu
[03:28:17] <seb_kuzminsky> if you look at the commit tagged "v2.6.8" you'll see what you're trying to create here
[03:28:21] <mozmck> I'm larnin' git a lot better these days
[03:28:31] <mozmck> ok
[03:28:39] <seb_kuzminsky> awesome :-)
[03:28:50] <mozmck> well, I better git!
[03:28:52] <seb_kuzminsky> ok, time for me to go tuck in my kids :-)

[05:01:45] <seb_kuzminsky> at least part of the merge difficulty is because JT-Shop reindented it in 2.7's 299eacb3f707d0f2d2dc6058512000c963bc7b68
[05:04:25] <seb_kuzminsky> so after trying to resolve the conflict, i can't see the diff i actually saved, because it's lost in 1443 lines of reflow changes
[05:05:21] <seb_kuzminsky> i will try building the html before and after the merge and diffing the html, that might subtract out the paragraph reflow

[14:12:52] <skunkworks_> seb_kuzminsky, I think the violations are rare and can be fixed in the 2.7.0~pre7. (with rob being so busy)
[14:13:10] <skunkworks_> and is as good as 2.6 with lots of improvemnts
[14:21:58] <mozmck> How bad are the violations?

[14:35:44] <skunkworks_> Yay!
[14:36:53] <seb_kuzminsky> i should write an email
[14:38:44] <jepler> seb_kuzminsky: thank you!
[14:38:59] <jepler> I don't know how many drinks I owe you by now, but it's more than you should have in one sitting
[14:39:30] <jepler> 22:25:37 <seb_kuzminsky> then "git push 2.6 v2.6.9"
[14:39:31] <seb_kuzminsky> heh, i feel the opposite way
[14:39:34] <jepler> should be git push origin 2.6 v.2.6.9
[14:39:40] <jepler> seb_kuzminsky: you feel like you could have them in one sitting?
[14:39:53] <seb_kuzminsky> you guys do all the work, i just push the releases out
[14:41:02] <seb_kuzminsky> you're right, i goofed the commandline i told mozmck
[14:41:26] <seb_kuzminsky> it's right on the webpage,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ReleaseCheckList
[14:41:53] <seb_kuzminsky> we should have a linuxcnc combined hackfest and drinking party
[14:42:11] <seb_kuzminsky> maybe we can call it a 2.7 release party? this fall some time?
[14:42:15] <skunkworks_> That sounds like a bug writing party..
[14:42:20] <seb_kuzminsky> heh
[14:42:23] <jepler> skunkworks_: a rule would have to be "no commits"
[14:42:35] <seb_kuzminsky> we'll temporarily revoke our commit access after the first round
[14:42:37] <jepler> seb_kuzminsky: is this a virtual party or a real party?
[14:42:45] <seb_kuzminsky> real
[14:43:04] <jepler> I wouldn't rule it out, I have been wanting to take a trip to Denver for ages
[14:43:10] <jepler> er, Boulder
[14:43:12] <jepler> well both really
[14:43:14] <seb_kuzminsky> heh
[14:43:25] <jepler> (Ingrid's going to Denver thursday and I'm jealous)
[14:43:36] <jepler> (a conference being held at the botanic gardens there)
[14:43:37] <seb_kuzminsky> we could hang out at the hackspace
[14:43:47] <seb_kuzminsky> there's power & wifi & some wonky machine tools
[14:43:55] <seb_kuzminsky> and couches that only smell a little funky
[14:44:04] <jepler> Make it after 9/18 and I'll attend

[14:44:13] <seb_kuzminsky> ok!
[14:45:10] <cradek> I'm absolutely in
[14:45:15] <seb_kuzminsky> sweet!
[14:45:40] <cradek> where?
[14:45:44] <seb_kuzminsky> Boulder's close to the geographic center of the US, so it's a good place to meet
[14:45:55] <cradek> I think the center of the US is the hub bar in north platte
[14:46:06] <seb_kuzminsky> otoh it's not close to the geometric center of linuxcnc people
[14:46:13] <cradek> but I don't recommend meeting there
[14:46:21] <seb_kuzminsky> there's a little town between lincoln and boulder called haxtun, which seems prophetic
[14:46:35] <seb_kuzminsky> dont know what their hackspace is like
[14:48:36] <cradek> we need to convince skunkworks to come so the center of people is near lincoln :-)
[14:49:40] <cradek> we could boldly update all my machines to 2.7

[17:14:55] <skunkworks_> X should be 30.
[17:15:21] <seb_kuzminsky> ouch
[17:16:17] <seb_kuzminsky> http://edushyster.com/wp-content/uploads/2012/09/barbie1.jpg
[17:16:51] <skunkworks_> it is. and mach is going to have a 3rd order planner when they get the time...
[17:17:06] <seb_kuzminsky> that would be awesome
[17:17:44] <seb_kuzminsky> i wonder what would make us renumber frmo 2.x to 3.0
[17:18:06] <skunkworks_> after seeing what it takes to get a decent working N-lookahead planner in linuxcnc - TP'ing is hard
[17:18:07] <seb_kuzminsky> i wonder if we should just drop the leading number
[17:19:00] <skunkworks_> 2.0 -> 3.0... JWP... ;)
[17:19:06] * seb_kuzminsky takes a drink
[17:19:17] <skunkworks_> Awesome!
[17:19:24] <archivist> ACD all can do
[17:19:53] <archivist> actually that is a stolen acronym :)
[17:29:09] <mozmck> re: what would make us renumber from 2.x to 3.0? That's easy, 3.0 comes after 2.9!
[17:29:35] <jepler> skunkworks_: I don't understand what I'm looking at in those two screenshots, can you explain?
[17:30:10] <skunkworks_> The X axis peak acceleration values on the right side. It should not go over 30in/s^2
[17:30:36] <jepler> skunkworks_: ah
[17:30:47] <seb_kuzminsky> skunkworks_: but 2.6 finishes it, right? with not worse violations than your first screenshot shows?
[17:30:49] <cradek> so both planners do it with about the same wrongness?
[17:30:53] <cradek> that's surprising
[17:31:13] <jepler> "both parties do it"
[17:31:20] <jepler> oops, sorry, I got politics in your cnc
[17:31:39] <skunkworks_> cradek, I have a feeling they are not in the same place..
[17:31:51] <skunkworks_> But I could surely check
[17:32:25] <jepler> what's the program, is it something real or something designed to frustrate TPs?
[17:32:25] <skunkworks_> seb_kuzminsky, I will let you know - but I have never seen the classic planner much over that in overages
[17:32:40] <seb_kuzminsky> thx
[17:32:50] <skunkworks_> jepler, it is tuxcnc that someone made - rotated and scaled.
[17:33:01] <skunkworks_> and moved
[17:33:10] <jepler> skunkworks_: ah I can sorta see tux hiding in there
[17:33:17] <cradek> tux doesn't even have arcs does it?
[17:33:25] <skunkworks_> this one does.
[17:33:28] <cradek> ah
[17:34:00] <skunkworks_> both - strait line segment paths + arcs
[17:34:07] <cradek> wonder what's special about X that makes them both get it wrong
[17:34:17] <cradek> with it rotated you'd think it'd be symmetric
[17:34:37] <jepler> .. because Yacc is higher?
[17:34:46] <jepler> maybe if you swap Xacc and Yacc you'd get the overage on Y
[17:34:49] <cradek> oh sure, it's the low one
[17:34:50] <skunkworks_> It is the lower acceleration axis. (I had changed it to Y and the violations followed)
[17:34:54] <cradek> ok
[17:34:58] <skunkworks_> right
[17:35:47] <skunkworks_> Rob knows about it - I gave him some examples. Unless someone else wants a stab at it.
[17:36:09] <skunkworks_> I guess I should have made a bug report.
[17:36:53] <cradek> were you able to isolate a little chunk of gcode?
[17:37:16] <skunkworks_> let me see how small it is.
[17:37:49] <skunkworks_> is robs stuff merged into 2.7?
[17:37:51] <jepler> it would be dandy if you could add "latch gcode line number on new worst violation"
[17:38:18] <cradek> oooh
[17:40:48] <skunkworks_> well - I kinda do that with halscope manually.
[17:41:09] <skunkworks_> run program once to get the worse - then run again with trigger set just under worse
[17:41:23] <skunkworks_> loggging program line
[17:41:49] <cradek> you could ddt the worst and trigger on >0
[17:41:50] <jepler> It looks like that program involves subroutines so just the line number doesn't capture everything
[17:41:57] <cradek> eww
[17:42:16] <jepler> I'm only assuming that, maybe it has the main body of tux repeated over and over again
[17:43:20] <skunkworks_> I also display the debug the degrees of rotations so I can figure out where in the code and what angle
[17:50:39] -!- sheppard has quit [Remote host closed the connection]
[17:51:24] <seb_kuzminsky> skunkworks_: yes, rob's feature/tangent-improvement-2.7-rebase is in 2.7
[17:51:48] <seb_kuzminsky> along with a ton of other bug fixes - it's been a good couple of days for linuxcnc improvements
[17:52:17] <skunkworks_> Ah - I missed that commit
[17:53:16] <skunkworks> cradek:
http://pastebin.ca/3099544
[17:54:18] <skunkworks> x=40in/s^2, y= 30in/s^2 Z=400in/s^2. all axis 8.333 (500in/s)
[17:59:03] <skunkworks> it doesn't violate on every iteration - but you can see the violations ramp up to a peak and then back down both positive and negative. The interesting thing is the y movements are only for fixture movements...
[17:59:31] <skunkworks> but I guess they are not during the normal gcode run.. that gcode snipit is in the middle of the gcode
[18:02:08] <cradek> ok, I see them
[18:02:36] <skunkworks> violations?
[18:02:40] <cradek> yeah
[18:03:22] <skunkworks> I am sure it could be just a little smaller..
[18:04:21] <cradek> ooh it's not at a blend

[18:45:16] <skunkworks_> cradek, can you test something while you have linuxcnc up.
[18:46:06] <cradek> bet we'd see a velocity violation too, if they were different

[19:15:41] <skunkworks_> It is funny that I cannot run this exact program on 2.6 because of arc end errors
[19:15:50] <skunkworks_> (a good thing I think)
[19:16:01] <cradek> you test the wildest things
[19:16:02] <cradek> it's great
[19:23:00] -!- SEL has quit [Quit: Leaving]
[19:24:56] <skunkworks_> those that can't - test
[19:26:44] <mozmck> heh, if you can't fix it, at least you can try and break it!
[19:27:19] <skunkworks_> exactly!
[19:27:39] <skunkworks_> I have found lots of bugs.. :)
[19:27:48] <mozmck> Sounds like a t-shirt idea...
[19:28:03] <skunkworks_> The K&T brought a bunch of stuff to light.
[19:28:13] <mozmck> Ah, yes.
[19:28:49] <skunkworks_> even before I broke the new TP
[19:29:34] <mozmck> They say testing is often better done by someone other than the developer.
[19:29:53] <cradek> oh absolutely
[19:30:31] <cradek> if a developer thinks of a certain problem, it's already probably coded correctly
[19:30:50] <cradek> testing just what you already thought of when you wrote it is not the best test
[19:31:29] <jepler> https://imgflip.com/i/pehh7
[19:31:54] <mozmck> maybe :)

[19:32:17] <mozmck> oh, bummer.
[19:32:31] <mozmck> Don't know why Tom did that.
[19:32:41] <jepler> skunkworks_: thanks for finding a pretty minimal test case for that one.
[19:32:48] <cradek> it's obnoxious and everyone seems to do it
[19:33:19] <mozmck> I have some checks on values sent to firmware in a board, and I reset to defaults if the values are out of bounds.
[19:33:48] <mozmck> Only problem was I reset one value to an out-of-bounds value accidentally.
[19:34:02] <cradek> oops!
[19:34:15] <skunkworks_> jepler, it is usually pretty easy to narrow it down to a few lines of gcode. Halscope tells me the line - I just whittle away until I can't anymore.
[19:34:21] <mozmck> User put in a value to low and it caused odd looking problems - until I looked at my firmware again.

[19:51:58] <cradek> skunkworks_: if you're curious enough, I'm thinking this should fix it in 2.6
[19:52:10] <jepler> geez time for 2.6.10
[19:53:55] <skunkworks_> If I get the time I will apply the patch to 2.6 and test
[19:54:21] <cradek> the patch won't work at all - code's completely different - try this cradek/2.6/bug430-fix branch
[19:54:30] <skunkworks_> duh
[19:54:31] <skunkworks_> yes
[19:54:47] <skunkworks_> when I saw that - I thought it was the same patch.
[19:58:10] <cradek> actually by looking at 2.6 I found a bug in my 2.7 patch
[19:59:07] <cradek> what if you only have X and Z axes and you rotate around Z
[19:59:14] <cradek> I imagine it shouldn't let you do that

[20:22:29] <seb_kuzminsky> cradek: i'd love it if you fixed a bug in a < 12 hours old release :-)
[20:23:20] <lerman> jepler... I saw your note about the dup o-word bug. It is doing exactly what I expect to do when it rereads a file. That's because the code "remembers" the addresses (file and line number) of all of the o-words it has seen.
[20:24:48] <lerman> It was originally written that way so that you wouldn't have to scan an entire file to find the subroutines in it. (Originally, you could have multiple subroutines in a single file.) The code should probably be changed to "forget" all owords in a file when the file is reread.
[20:27:27] <jepler> lerman: thanks for the background
[20:30:55] <lerman> I do prefer the original way it worked. When a subroutine was called, first it looked to see if it had already been seen. If not, it found the file with the appropriate name and scanned the entire file looking for subroutines. So I could have a probing library in a single file. Call o<safe_probe_init> to initialize it. After scanning safe_probe_init.ngc, it would then know about all of the subroutines in the lib
[20:30:55] <lerman> rary. The way it works today, I put all of the routines in the same library, but then have to have a symbolic link for each of the routines in the library. Just more stuff to do with no value (to me, at least).
[20:32:25] <cradek> I don't know how, why, or when that changed
[20:37:09] <lerman> Every time you call a subroutine, the file is "seeked" to the memorized location of the subroutine. So editing the file can have nasty results (unless someone has added code to avoid that). It can wind up seeking to the middle of a line. In some ways it would be cleaner if it just didn't bother remembering anything in subroutine files. That would be less optimized, but conceptually cleaner. And it would work the
[20:37:09] <lerman> way people might expect it to work.
[20:37:43] <cradek> would it seek from the beginning each time?
[20:38:01] <lerman> The alternative is to put in the optimization, but add code to forget the contents of the file. Then each time a routine is called, a check could be made to see if the file had changed.
[20:38:57] -!- eFuchs has quit [Remote host closed the connection]
[20:39:35] <lerman> Right now, it does a seek each time. Remember that files are not stored in memory. Only the locations of the owords (filename and linenumber) are stored. {Note: I'm describing the way it was originally written -- who knows what the last hands on the code did to it.}
[20:40:08] <cradek> certainly noted
[20:40:25] <lerman> Of course, the file actually is stored in memory -- by the operating system to the degree that there is plenty of memory to store recent files.
