| === mark_ is now known as mark | ||
| mark | cjwatson: I had our on-site tech investigate that "man-db" problem | 04:55 |
| mark | which isn't man-db but most often occurs during that postinst | 04:55 |
| mark | it seems to be a deadlock | 04:55 |
| mark | perl seems to try to read from a dpkg pipe | 04:55 |
| mark | and dpkg is wait4() for perl | 04:55 |
| mark | at least that's what my on-site tech tells me, a little hard to get more info | 04:56 |
| mark | I should just always run it in strace, then the deadlock does not happen due to other buffering/context switching ;) | 05:23 |
| cjwatson | perl would be debconf | 07:51 |
| cjwatson | so again, it's probably a failure to close some file descriptor, possibly racily | 07:52 |
| mark | not the commonly made mistake of writing and reading from a child processes's pipes at the same time? :) | 08:25 |
| cjwatson | I sincerely hope not | 08:25 |
| cjwatson | no, more usual with debconf is spawning something from a debconf confmodule that daemonises but forgets to close the debconf fds | 08:25 |
| cjwatson | man-db does background itself under certain circumstances, but I thought that (a) it didn't do that under the noninteractive frontend to avoid pretty much this problem and (b) it disconnected properly anyway ... | 08:26 |
| mark | ok | 08:28 |
| mark | yeah but it's not just man-db | 08:28 |
| mark | for example, today sometimes it got stuck on openssh | 08:28 |
| mark | and occasionally on other stuff | 08:28 |
| mark | just most often man-db | 08:28 |
| mark | today we reinstalled 20 servers and only *one* went through without problems | 08:29 |
| cjwatson | your libc isn't spawning some weird NSS thing, is it? | 08:29 |
| mark | ehm | 08:43 |
| mark | our libc? | 08:43 |
| mark | it's just the ubuntu installer :) | 08:43 |
| mark | not doing anything special in that regard | 08:43 |
