[nbdkit PATCH 0/2] retry: add support for retrying .open
In https://bugzilla.redhat.com/show_bug.cgi?id=1841820, it was pointed
out that the retry filter not retrying .open means that an ssh
connection (such as in a vmx+ssh v2v conversion) fails when the ssh
connection itself cannot be retried. A year ago, this was an inherent
limitation of our retry implementation; but in the meantime, my work
to allow filters to open independent backends has made it

[PATCH nbdkit 0/2] Add new retry filter.
This is a retry filter implementation as outlined here:
https://www.redhat.com/archives/libguestfs/2019-September/msg00167.html
It is only lightly tested. One way to test it is to try an SSH copy
(see the commit message for patch 2/2), and in the middle of the copy
kill the per-connection sshd on the remote machine. You will see that
the copy recovers after a few seconds. Add the nbdkit -v

[PATCH nbdkit v2 0/4] Add new retry filter.
v1 was here:
https://www.redhat.com/archives/libguestfs/2019-September/msg00199.html
v2:
- Adds a fairly simple yet comprehensive test using sh plugin.
- Rebase and retest.
Patch 1 is a misc patch not really related to the series.

[PATCH nbdkit v3 0/3] Add new retry filter.
v2 was here:
https://www.redhat.com/archives/libguestfs/2019-September/msg00221.html
I think this is more like "the one". It handles reopen failing
correctly, and there is a second test for that. I also ran my sshd
tests locally and it worked in all scenarios I could think up (except
of course sshd not being available at the start, but we want that to
fail).

[nbdkit PATCH v2 0/6] Improve retry filter
Includes a rework of the previously posted patch for --run
improvements (mostly with improved comments and commit message; I
decided that waiting for the captive nbdkit to exit was overkill), and
four new patches. The tests are intentionally separate, to allow
rearranging the order of the series to see the failures being fixed.
