      X wcfs: Care to disable OS polling on us · 59552328
      Kirill Smelkov authored
      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.

      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
      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.
