Don Lewis <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Don Lewis <[email protected]> --- I don't see this with slightly older -CURRENT (r299612) It may also be dependent on the write size with partial writes being the trigger. This is how I did my test: # truss -do /tmp/truss.out cat /usr/share/dict/web2 | & ( sleep 60 ; cat > /tmp/out ) The point at which the pipe file is visible here: 0.008018050 write(1,"\nalif\naliferous\naliform\nalig"...,4096) = 4096 (0x1000) 0.008089335 read(3,"oplasmatic\nalloplasmic\nallopla"...,4096) = 4096 (0x1000) 0.008183362 write(1,"oplasmatic\nalloplasmic\nallopla"...,4096) = 4096 (0x1000) 0.008255003 read(3,"\naltininck\naltiplano\naltiscop"...,4096) = 4096 (0x1000) 0.008353817 write(1,"\naltininck\naltiplano\naltiscop"...,4096) = 4096 (0x1000) 0.008425411 read(3,"ambrosiate\nambrosin\nambrosine"...,4096) = 4096 (0x1000) 60.037870962 write(1,"ambrosiate\nambrosin\nambrosine"...,4096) = 4096 (0x1000) 60.038272972 read(3,"n\nAmnionata\namnionate\namnioni"...,4096) = 4096 (0x1000) 60.038579389 write(1,"n\nAmnionata\namnionate\namnioni"...,4096) = 4096 (0x1000) I just tried an odd-size write test and that works properly as well: # truss -do /tmp/truss.out dd if=/usr/share/dict/web2 bs=111 | & ( sleep 60 ; cat > /tmp/out ) 0.281516906 read(3,"\namboceptor\nAmbocoelia\nAmboin"...,111) = 111 (0x6f) 0.281774261 write(1,"\namboceptor\nAmbocoelia\nAmboin"...,111) = 111 (0x6f) 0.281966423 read(3,"n\nambrein\nambrette\nAmbrica\na"...,111) = 111 (0x6f) 0.282239613 write(1,"n\nambrein\nambrette\nAmbrica\na"...,111) = 111 (0x6f) 0.282433782 read(3,"ous\nambrosial\nambrosially\nAmb"...,111) = 111 (0x6f) 60.078868711 write(1,"ous\nambrosial\nambrosially\nAmb"...,111) = 111 (0x6f) 60.079279323 read(3,"y\nambsace\nambulacral\nambulacr"...,111) = 111 (0x6f) 60.079588632 write(1,"y\nambsace\nambulacral\nambulacr"...,111) = 111 (0x6f) 60.079823710 read(3,"ative\nambulator\nAmbulatoria\na"...,111) = 111 (0x6f) 60.080113161 write(1,"ative\nambulator\nAmbulatoria\na"...,111) = 111 (0x6f) -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
