X wcfs: Care to disable OS polling on us · 59552328

Kirill Smelkov authored Mar 04, 2019

If we don't early-disable it, we can see a situation where when
handling invalidations wcfs calls open("@revX/bigfile/...") to upload
cache data there, go runtime tries to use epoll on that fd, and it gets
stuck as described in the commit referenced in comments.

In particular the deadlock was easy to trigger with nproc=1 environment
(either a VM with 1 cpu, or e.g. under `taskset -c 0`)

Bug reported by @romain.

t/qemu-runlinux: Mount bpf and fusectl filesystems · a568d6d9

Kirill Smelkov authored Feb 27, 2019

bpf is needed for tools like bpftrace.
fusectl is needed to observe things like /sys/fs/fuse/connections/X/waiting.

t/qemu-runlinux: Issue terminal resize before running program · 6ab95220

Kirill Smelkov authored Feb 27, 2019

Else program inside sees default terminal settings to be 80x25,
while after the patch it sees correct settings.

Still something is not completely right with terminal settings, as e.g.
vsplit is not working correctly in vim (vertical ruler is not straight).

t/qemu-runlinux: Don't propagate $TERM in graphics mode · ccca055c

Kirill Smelkov authored Feb 27, 2019

Graphics mode runs in another window with its own terminal emulation,
so propagating e.g. TERM=xterm to where it is emulated as TERM=linux is
not correct.

Wcfs was not yet optimized at all. Offhand `perf top` was showing lots of time
is spent in garbage collector, but maybe something to also debug on FUSE-level latencies.
In any way FileStorage case is not very representative and as for ZEO/NEO case
there are network requests to be made and they start to dominate the latency to
access one page/object.

t/qemu-runlinux: Update · fe541453

Kirill Smelkov authored Feb 13, 2019

Continuing 76d8f76d (Script to run compiled linux kernel with root fs
mounted from host) update the script to run/debug linux inside QEMU:

- teach it to run specified program + args, instead of hardcoded /bin/sh;
- before tailing to user program, builtin init mounts /proc, /sys, ...
  inside - previously it was /proc, /sys from host seen on those
  mountpoints and it was very misleading - e.g. ps was showing processes
  from host, not inside, etc.
- builtin init also cares to run specified program with the same current
  directory that was current on host, and environments such as $HOME,
  $PATH, $TERM, ... are also propagated.
- allow to optionally run QEMU with graphics, instead of stdout only;
- increase available RAM from 128M to 512M (with 128M running py.test
  inside is failing with fork: not enough memory).

This updated version was useful to debug WCFS(*) & FUSE issues by running

	kirr@deco:~/src/wendelin/wendelin.core/wcfs$ ../t/qemu-runlinux ~/src/linux/linux/arch/x86_64/boot/bzImage py.test -vsx -k test_wcfs

See https://marc.info/?l=linux-fsdevel&m=155000277921155&w=2 for details.

(*) WCFS is still being draft and worked on t branch.
