| AlexDaniel | timotimo: can we figure out why it happens? | 10:38 | |
| timotimo | probably, with a bit of work | 10:40 | |
| the first step might be to ensure we have a working shell on the vm even when the disk has disappeared, for example by leaving a root shell open (sounds like a great idea!) logged into a statically compiled busybox that's been loaded into memory completely | 11:16 | ||
| that way we'd be able to poke around in /sys and /proc and such | |||

|
|||
| timotimo | i don't know | 11:50 | |
| and i'm not entirely sure how to find out :) | |||
| hm. an rsyslog daemon is running, but /var/spool/rsyslog is empty, so it's probably not going there | 11:54 | ||
| oh, maybe the logs actually go to www.p6c.org | 11:58 | ||
| at least there's an entry in /etc/rsyslog.d/remote_www.p6c.org.conf on hack | |||
| yeah, they live in /var/log/hack.p6c.org/ | 12:00 | ||
|

[Tux] joined
|
|||
| timotimo | it doesn't seem like the logging actually reaches www, though | 12:02 | |

|
|||
| timotimo | i wonder if rsyslogd on hack dies from lack of disk and doesn't continue with the next output, so before it can send logs it waits forever for some disk access to finish | 12:03 | |
| nine | Sounds reasonable. Is it possible to switch the outputs? | 12:05 | |
| timotimo | surely | 12:08 | |
| hm | 12:11 | ||
| the include directive is in front of the rules that split the log messages into different files | |||
| but i don't know if it's "ordered" | 12:12 | ||
| nine | Wait, does it log anything at all to www? | 12:16 | |
| timotimo | yes | ||
| nine | Ok, so we're really just missing the interesting log entries | ||
| timotimo | i think so | ||
| or perhaps those aren't even reaching rsyslog | |||
| no clue, tbh | |||
| nine | Is rsyslogd the only loggin daemon or is journald involved, too? | 12:18 | |
| timotimo | i believe journald also runs, yeah | ||
| it gets kernel messages | |||
| ah, and a bunch of other stuff, too | 12:19 | ||
| looks like everything | |||
| nine | Maybe using systemd-journal-remote is more reliable? | ||
| timotimo | perhaps rsyslogd gets its data from journalctl? | ||
| could be. do you want to set it up? :) | |||
| nine | Nice. The journal supports both push and pull | 12:25 | |
| But hack is a debian system and I don't have sudo rights and this apt stuff looks much more complicated than zypper | 12:28 | ||
| timotimo | heh. | 12:31 | |
| i'm lots distracted ATM | 12:32 | ||
| nine | Btw. looks like I actually don't need $*MAST_FRAME at all. I can put it into an attribute in QASTCompilerMAST just as easily. | ||
| timotimo | oh! | 12:33 | |
| that should give another percent or two | |||

| camelia | ([], [Slip, Slip]) | ||
| lucasb | Shouldn't a Slip type object be as slippery as a concrete slip value? | ||
| timotimo | no, type objects are always itemy | 15:41 | |
| lucasb | ah, right. thanks | 15:42 | |
| nine | timotimo: btw. your hint to set $!index as box_target in MAST::Local was just great! | ||
| Saves so much coercion and boxing | 15:43 | ||
| timotimo | <3 | 15:44 | |
| glad to hear it | |||
| hm, actually, they might sometimes not be itemy, probably some way to override that behaviour | 15:45 | ||
| lucasb | 'Nil.new =:= Nil' is always true. Do you think makes sense to make argument-less slip 'Slip.new =:= Empty' be true? | 15:57 | |
| in Slip.pm: multi method new(--> Empty) {} # ? :) | 15:59 | ||
| timotimo | that way you could "does" Empty and get the same changes every time you write Slip.new | 16:03 | |
| lucasb | hm, not sure I understood :) | 16:07 | |
| m: use MONKEY-TYPING; Empty does role { method foo { 42 } }; augment class Slip { multi method new(-->Empty) {} }; dd slip.foo | |||
| camelia | 42 | ||
| lucasb | ^^ related idea? | ||
| timotimo | yeah | 16:08 | |
