<apteryx>any tip to debug dependency cycles between top level variables?

<apteryx>can I ltrace or use gdb in a way to gather some clues as to what is causing the loop?

<apteryx>(I tried and failed thus far)

<apteryx>the system just goes on eating memory and I have no clue what's going on other than it happens in guix when I make pkgconf the default instead of pkg-config

<old>apteryx: have you tried perf?

<old>If there is a infinite loop somewhere, perf ought to show you were

<old>where*

<apteryx>perf tracks system calls?

<old>not really

<old>for syscall, strace can be used

<apteryx>do you use a viewer to visualize perf's output?

<old>perf report

<old>it's a TUI base viewer

<dsmith>sneek, botsnack

<sneek>:)

<dsmith>!uptime

<sneek>I've been a process for 2 months

<sneek>This system has been up 43 weeks, 5 days, 21 hours, 54 minutes

<apteryx>old: I've tried 'perf record' then 'perf report'. It tells me most time was spent in libgc or libguile

<old>apteryx: What about syscall? Have you tried strace?

<apteryx>this is gdb and perf's output: https://paste.debian.net/1306145/

<old>nothing out of the ordinary with perf

<old>does the thread ever quit scm_reverse (frame #0)?

<old>if you have a reproducer with Guix, I could try to debug it from my gdb

<apteryx>you could build the wip-cu-switch-to-pkgconf branch from the guix repo

<apteryx>and try './pre-inst-env guix build anything'

<apteryx>e.g. './pre-inst-env guix build hello'

<old>what's the environment you use for building Guix?

<apteryx>pretty much 'guix shell -D guix'

<old>I use: guix shell --pure -D guix guile

<old>okay

<old>I'm compilining stuff

<old>brb

<apteryx>the strace looks like https://paste.debian.net/1306147/
