13:23 bvt http://bvt-trace.net/2020/02/a-tiny-and-incomplete-trb-wedgetrace/#comment-139 - did some more debugging today, but cannot get a wedge when i do need it
13:27 mp_en_viaje bvt, don't feel too bad, this is a massive problem owing to the insanity of the gearbox involved. the vast majority of historically observed wedges were never reproduced
13:27 mp_en_viaje i guess in some quarters this counts for "intrinsic stability" or something, but...
13:30 bvt well, the only thing i feel bad about in this situation is that for some time i was getting wedged in ~30 min, did not check the logs, assumed the DB corruption, rolled back to month-old chain snapshot without keeping the current

13:50 bvt anyone debug.log snapshots of wedge: did the period before wedge involve a large number of continous block requests?

16:01 mod6 bvt: Yes, I experience exactly like you describe; right before 'wedge', incoming 30k or so of 'received getdata for: block' in debug.log.
16:05 mod6 I have a debug.log that is ~12G that goes back ~3 mos to block #605198, i do see those requests, but in the dozens at a time at most. but not a tidal wave of tens of thousands.
16:06 mod6 When alf alerted about this wedge on the 22nd, I was quick to point out this wave of stuff that I don't typicaly see.
16:06 mod6 Happy to provide the 12G log if you want that, or a shorter one that shows on 22nd or 23rd my node starting, then getting wedged after wave.
16:10 mod6 Apparently main.cpp:ProcessMessage() allows for quite a number of these getdata commands before flagged as 'Misbehaving'. But I've not seen waves like this before now. Quite possible I've just not seen them either tho.

16:18 mod6 Here's that quick deebot snippit I posted on Friday night (iirc): http://paste.deedbot.org/?id=Oj7N

16:34 mod6 If others have this same type of behavior, please write in and say, show us the debug.log if you can. Thanks.

17:20 mod6 bvt: et, al. Was able to use alf's wedger tool to replicate the problem. It took exactly 1 try. Here's my notes and debug.log (renamed) from the test: http://www.mod6.net/wedger/mod6_wedger_test1.log http://www.mod6.net/wedger/trb_debug_wedgerpy_test1.log

19:46 mod6 bvt: et, al. Still testing/debugging. Tried an experimental vpatch, didn't work. Going to make some changes and continue on. Here's the latest logs for the curious: http://www.mod6.net/wedger/mod6_wedger_test2.log http://www.mod6.net/wedger/trb_debug_wedgerpy_test2.log
~ 3 hours 9 minutes ~
22:55 mod6 Alright, got a fix for this. *whew*
22:58 mod6 Took some work and chasing some red-herrings in net.h. I drove through the testing and changes while asciilifeform helped think me through the problem.
22:59 mod6 Going to push up my logs & notes, and then make a vpatch.
~ 20 minutes ~
23:20 mod6 Ok all of the logs are in http://www.mod6.net/wedger/
~ 31 minutes ~
23:51 mp_en_viaje mod6, suppose instead of all this ad-hoc "emergency" pantsuit nonsense you make a proper blog, like normal people, follow the path, like normal people, etcetera.
23:52 mp_en_viaje or what exactly is the idea, erryone's gonna be so fucking impressed with the whole "oh, you know what, ye olde bitcoin has, among its many race conditions, one where you can dos it by getblock spam" that we'll just move right back on to 2015 ? it ain't ever gonna be 2015 again, make a blog, find a master, do some work AS THEY DIRECT YOU, and so on.
↖
23:53 mod6 I'll make a proper post on my blog, indeed. Just want to get this out for folks; now that there is a wedger tool out there, and it's been a number of days of reorccuring wedges.
23:54 mp_en_viaje 0 chances ima deploy some patch you cooked up as things stand right now. also 0 chances ima deploy any patch baked of this "21:02. tried a patch, not worked. 00:12 oh now fixed it. i think" washington post / planeshift "development" model/nonsense.
23:54 mp_en_viaje what "folks" dude ?
23:54 mp_en_viaje who are these "folks" consuming this nonsense ? i've never met one. did you ?
23:55 mod6 I suppose not.
23:55 mp_en_viaje i met plenty of would-be producers. what's the actual market for it /
23:55 mod6 I'll just, withold the patch. Make a blog post. If people want it, I guess they can say.
23:55 mp_en_viaje you wanna be useful, be useful in the way of being useful, not in the way of you wanna.
23:56 mod6 Anyway, I haven't even eaten today. So I'm gonna head out.
23:56 mp_en_viaje yes, indeed. asciilifeform has a whole lot of those. can sure take more -- the overwhelming abundance to date hasn't bothered anything, so definitely could double, triple, infinite-etc.
23:56 mp_en_viaje laters.
