[15:29:59] <andypugh> Can I tell which version of LinuxCNC a particular commit is in?
[15:30:18] <andypugh> Specifically http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=commit;h=a3719bd5a9a6c64326a4d1ac9c32fe06385f07cf
[15:30:45] <andypugh> I feel that I am missig some obvious way of telling that it went into 2.5 or master.

[15:48:29] -!- kmrhb has quit [Ping timeout: 255 seconds]
[15:48:59] <cradek> if I do gitk a3719bd, I see it "Follows:" v2.5.0
[15:58:19] <andypugh> Ah, OK, so the information is not readily avalable on Gitweb?
[15:59:35] <cradek> it might be, but I don't know how to get it. gitweb is pretty useless for understanding history.
[15:59:54] <cradek> I don't recommend trying to use gitweb for anything but pointing to one commit
[16:01:31] <andypugh> OK. I find it very handy sometimes during luch break at work, as I haven't set up any remote access to my home network
[16:02:28] <cradek> ah
[16:02:39] <cradek> I really wish it was better
[16:02:49] <cradek> it's sad that it's not as useful as cvsweb was
[16:04:32] <jepler> I think that commit is not in any released version
[16:04:48] -!- fragalot has quit [Ping timeout: 256 seconds]
[16:05:18] <cradek> I thought it was between v2.5.0 and v2.5.1
[16:05:36] <jepler> $ git describe --match="v*" --contains a3719bd5a9a6c64326a4d1ac9c32fe06385f07cf
[16:05:40] <jepler> fatal: cannot describe 'a3719bd5a9a6c64326a4d1ac9c32fe06385f07cf'
[16:05:41] <cradek> maybe I don't know how to figure that out either
[16:05:46] <jepler> there is no tag matching 'v*' that contains that commit
[16:06:04] <jepler> for a commit that's in v2.5.1, you would see output like this>
[16:06:05] <jepler> $ git describe --match="v*" --contains b6b2c6343a700eb997fc57b648cc7b675beb8d82
[16:06:08] <jepler> v2.5.1~61^2
[16:06:49] <cradek> huh
[16:07:37] <jepler> dgarr's suggestion will show you what local branches contain the commit. This variant will show you which branches it's in on your origin repository (presumably git.linuxcnc.org): $ git branch -r --contains a3719bd5a9a6c6432 | grep origin/
[16:07:53] <jepler> and there it can be seen to not be on v2.5_branch, so no surprise if it's not in any v2.5 release
[16:08:32] <dgarr> i think git tag --contains works (a3719bd5a9a6c6432 is not on any tag)

[16:41:13] <andypugh> (Files away for future reference)
[16:41:49] <andypugh> So, quadrature error detection is only in Master? That's a slight pity.
[16:45:40] <cradek> well he's decided it's a software problem :-/
[16:46:21] <cradek> he didn't carefully describe what he's seeing. I assume it's cumulative creep in actual motor position (not DRO position) but he doesn't say that.
[16:47:37] <cradek> > Then when I say (G0 x0) it will go to x-70.
[16:48:00] <cradek> if it's the DRO showing that x-70, it's not encoder noise
[16:48:21] <cradek> a much more precise description is needed IMO
[16:49:00] <andypugh> I find it quite amusing to try to guess what the problem is that they are not describing :-)
[16:49:42] <cradek> I find it so irritating that I refuse to do it
[16:50:10] <cradek> I can sometimes be bothered to ask for better information, but usually not even that

[16:56:43] <pcw_home> I am presuming he means the physical position is -70 mm and the
[16:56:45] <pcw_home> DRO reads 0 on a G0 X0 move but I just asked to make sure
[16:57:11] <pcw_home> (~1% lost counts if so)
[16:58:02] <cradek> I bet he could see it on a (real) scope
[16:58:53] <pcw_home> Yep
[16:59:21] <cradek> when I was working on a problem like this, I could grab the screw and give it a twist. one way, it would push back normally, the other way, I could occasionally feel a little position jump that represented 4 counts worth of lost position
[16:59:57] <cradek> the 4-count jump was evident on halscope
[17:02:04] <pcw_home> Noise does not seem likely to be affected by direction
[17:02:19] <cradek> in this case it was fixed by fixing the grounding
[17:02:35] <cradek> but I agree he's going to probably see some asymmetry or other defect in the quadrature
[17:03:14] <pcw_home> I wonder if the quadrature is from an encoder or a drive
[17:04:33] <pcw_home> Ive seen seem flaky behavior if the TTL/DIFF mode is wrong
