18:36:25 <rayh> Got this after an attempt to get a reply from halcmd save comp.
18:36:31 <rayh> any clues?
18:38:17 <rayh> and "sudo rmmod hal_m5i20" fails to remove the module.

19:08:09 <SWP_Away> hiya Ray
19:09:08 <rayh> Hi steve.
19:09:15 <SWP_Away> when you got that error, had you loaded any modules with long parameter strings?
19:09:46 <rayh> It was a m5i20
19:10:00 <rayh> let me look for the longest param string.
19:10:06 <SWP_Away> I haven't loaded the driver (ever :) ), though I finally installed the card in the machine
19:10:48 <SWP_Away> there is a bug in halcmd when saving the parameters, so that may be the cause of the problem if there are long lines
19:11:36 <rayh> 5i20.0.digital-out-write.tmax looks like the longest
19:11:46 <SWP_Away> I mean the loadrt line
19:12:02 <rayh> oh.
19:12:05 <SWP_Away> like loadrt m5i20 foo=123;bar=thisisalongparameter
19:12:37 <SWP_Away> heh - funny how you see ambiguity in retrospect
19:12:55 <SWP_Away> (I wouldn't have though of that interpretation, but now that you mention it ... ;) )
19:13:03 <SWP_Away> thought
19:14:45 <rayh> loadrt classicladder_rt numRungs=4 numBits=16 numWords=4 numTimers=2 numMonostables=2 numPhysInputs=16 numPhysOutputs=8 numArithmExpr=4 numSections=1
19:15:01 <rayh> would probably qualify as a long loadrt string
19:15:10 <SWP_Away> ok - the same one that was truncated in jmk's initial output
19:15:11 <SWP_Away> yep
19:15:15 <rayh> but it isn't started by default
19:15:24 <SWP_Away> before he increased the max string length
19:16:03 <SWP_Away> I can't fix the bug now, but I'll describe it so it's in the logs
19:16:56 <SWP_Away> in the parameter save code, the arguments are copied into the arg_string, using strncpy
19:17:20 <SWP_Away> the max length is MAX_CMD_LEN each time strncpy is called
19:17:25 <SWP_Away> strncat, I mean
19:17:57 <SWP_Away> this allows the string to grow without bound, since up to MAX_CMD_LEN bytes can be added for each arg on the command line
19:18:37 <SWP_Away> this may be OK, since the data is hal_malloc'd later, but it probably isn't what was intended (or MAX_CMD_LEN ishould MAX_TOKEN_LENGTH or something else)
19:18:42 <rayh> ok I can see that
19:19:16 <SWP_Away> ok
19:19:47 <SWP_Away> ah - OK, it is a potential problem, since arg_string is MAX_CMD_LEN+1 bytes long
19:20:51 <rayh> No hurry.  I've got plenty to work on with watching and editing.
19:21:06 <SWP_Away> heh - if you overwrite the end of arg_string, you screw up n, the token index in that loop (oops) :)
19:21:15 <SWP_Away> yep
19:21:30 <SWP_Away> one day soon, I'll fire up hte emc machine again - right now there's too much other stuff to do
19:22:34 <SWP_Away> speaking of too much time on our hands, are there any plans for a Fest'06 yet?  :)
19:23:59 <rayh> jmk was talking about having it along with -- before or after cnc-workshop in may.
19:24:23 <SWP_Away> OK - that's in Indiana or something?
19:24:25 <rayh> Roland of Cardinal said he would be happy to host the extra session.
19:24:59 <rayh> though he prefered after.  In western IL  not far from Davinport iowa
19:25:05 <SWP_Away> ok
19:25:16 <cradek> yay IL
19:25:27 <SWP_Away> after probably makes sense, since we may learn some new features at the workshop
19:25:38 <SWP_Away> features / bugs / ...
19:25:39 <rayh> Not quite so far.
19:26:07 <rayh> And we have immediate access to test machines.
19:26:25 <rayh> so it need not all be code
19:27:18 <rayh> We should talk about it -- perhaps this sunday
19:27:20 <SWP_Away> NO RETROFITS!  :)
19:27:46 <rayh> swp slaps rayh for last year?
19:27:51 <SWP_Away> but I'm sure you know that better than I
19:27:53 <SWP_Away> nope
19:27:59 <SWP_Away> I wasn;t there, remember? ;)
19:28:14 <SWP_Away> (at least at MazakFest)
19:28:25 <rayh> The Mazak will be there, right across the parking lot.
19:28:53 <SWP_Away> as long as the retrofit is done, that's OK
19:29:14 <SWP_Away> it might be fun to try a "non-standard" retrofit, like a bandsaw or lathe
19:29:17 <rayh> Yes it will be.
19:29:30 <rayh> Feature add time by then.
19:31:14 <SWP_Away> it would be good to have access to appropriate machines for certain features, like threading
19:32:37 <rayh> I like the idea quite a bit.
19:32:49 <rayh> Plenty of classroom space.  Plenty of internet.
19:33:02 <SWP_Away> sounds good to me
19:33:06 <rayh> No limit to open hours
19:33:19 <SWP_Away> no security cards/guards ...
19:33:33 <rayh> Inexpensive hotels and food not to far away.
19:34:04 <rayh> Reminds me of my recent conversation with a sherline users at Los Alamos National Labs.
19:34:25 <rayh> talk about guarded to the point of paranoia
19:34:44 <SWP_Away> indeed, especially after the nuclear secrets problems (they had some of those, right?)
19:34:46 <cradek> yay, Davenport IA is only 350 miles from me
19:35:09 <cradek> ohh IL, not IA
19:35:11 <cradek> duh
19:35:52 <SWP_Away> 1120 miles for me - hmmm
19:35:54 <cradek> I'm so confused, forget it
19:36:03 <rayh> cradek: is closer than rayh -- 500 even from here
19:36:28 <cradek> SWP_Away: that's a long drive even split to two days
19:36:33 <SWP_Away> Galesburg, IL
19:36:43 <SWP_Away> ok - 1130 miles to Galesburg ;)
19:36:47 <rayh> SWP_Away: Need me to pick you up at an airport?
19:37:04 <SWP_Away> possibly.  I had hoped to be able to drive so I can bring computer stuff along
19:37:21 <cradek> flying into chicago would be cheap from anywhere
19:37:23 <SWP_Away> the laptop doesn't cut it for m5i20 and the like
19:37:41 <SWP_Away> I wish I were 13 miles closer to Chicago - it would then be only 15000 miles for a free flight
19:37:57 <SWP_Away> (I'm 763 away, the limit is 750)
19:38:19 <rayh> Ah.  I could probably bring several extra tower boxes.
19:38:34 <cradek> I would want to take my mill and everything, which means driving
19:38:38 <cradek> no way would I ship it
19:38:44 <rayh> hang them off a network with ssh -X setup.
19:38:45 <SWP_Away> I was thinking of my dual Opteron, for SMP and 64-bit testing, plus my kiosk machine for m5i20 and other PCI tests
19:39:04 <rayh> Better drive then.
19:39:10 <SWP_Away> heh
19:39:19 <cradek> 1100 miles is possible over two days
19:39:30 <cradek> but what a drag
19:39:31 <SWP_Away> we have two vehicles now, so I can bring lots of stuff in the minivan
19:39:49 <SWP_Away> I've driven to Austin TX from here in two days - driving doesn't bother me
19:40:35 <SWP_Away> (a little over 2000 miles, and I made it by 8:00 PM the second day)
19:40:40 <rayh> There you go.
19:41:06 <SWP_Away> actually, I think I went 2200 miles - I took the southern route
19:41:08 <cradek> for me the harder part is driving home afterward
19:41:15 <SWP_Away> heh
19:41:29 <cradek> staying up late, sleeping in motels, etc
19:41:43 <SWP_Away> I have a friend in Pittsburgh - not that I'd want to leave $6k worth of computers in the car overnight
19:41:55 <rayh> Yep.
19:42:01 <SWP_Away> I'm not sure I'd want to leave the car overnight, actually ;)
19:42:34 <SWP_Away> though he does, so it probably isn't too bad
19:53:55 <rayh> just started up a scripts/realtime added two ddt's and tried save comp
19:54:07 <rayh> # components
19:54:08 <rayh> loadrt blocks ‰D$‹A‰$èàúÿ¸/
19:54:20 <SWP_Away> oops - that looks incorrect
19:55:15 <rayh> seems so but what do I know.
19:55:39 <rayh> I did just make clean and reinstall so the binaries should be okay.
19:55:44 <SWP_Away> hmmm
19:56:10 <SWP_Away> that was "bin/halcmd loadrt blocks ddt=1" or similar?
19:56:14 <SWP_Away> ddt=2
