Can you share exactly how you are using copy_in? A small
reproducer would be good.

Accessing qcow2 images on GlusterFS
by Seyed Mohammad Fakhraie
Hello folks,
I've set up a distributed storage volume with GlusterFS (version 5.5)
to store my VM images. My host operating system is Debian 10; I'm
using guestfish 1.40.2 via CLI. It was installed via apt. I can't
access or run any guestfs utilities on images which are stored on
GlusterFS (I'm using FUSE; I only try to access the images with
guestfs when a VM is turned off).
This is a sample command that I'm trying to execute:
guestfish --rw -a
gluster://storage-node0/gv0/vm/ff9cdab3-8f3e-4f53-a907-e5c8e57588a4.img
-i command "bash -c \"echo root:fish123 | chpasswd\""
Which gives an error about "the appliance closing the connection
unexpectedly" and points to the output of 'libguestfs-test-tool' for
further debugging.
I will post the complete output of 'libguestfs-test-tool' below:

[nbdkit PATCH] error: Tweak filter name for easier debugging
by Eric Blake
Grepping for the string 'error:' is complicated when the error filter
reports its name in the same manner. We can keep the filter .so and
file names the same, but tweak the filter .name field to change
messages using nbdkit_debug() to instead produce "error-inject:", so
that "error:" is reserved for uses of nbdkit_error().
---
I confused myself while trying to debug a new libnbd today, where
injecting errors was intentional. And then I noticed that 'man
nbdkit-error-filter' already tried to warn me. But we can do one step
better, as in this patch...

[PATCH libnbd] golang: tests: Fix error handling
by Nir Soffer
Like lot of the C examples, the aio copy test ignores read and write
errors in the completion callback, which can cause silent data
corruption. The failure in the test is not critical, but this is a bad
example that may be copied by developers to a real application.
The test panics now if completion callback fails, similar to other Go
examples.

[libnbd PATCH] docs: Clarify how callbacks should handle errors
by Eric Blake
Recent patches have demonstrated confusion on which order callbacks
are reached, when it is safe or dangerous to ignore *error, and what a
completion callback should do when auto-retirement is in use. Add
wording to make it more obvious that:
- mid-command callbacks are reached before the completion callback,
and returning -1 does not prevent future callbacks
- ignoring *error in a mid-command callback is safe
- completion callbacks are reached unconditionally, and must NOT ignore
*error
- if auto-retirement is in use, completion callbacks should always use
it rather than trying to return -1 on error
- the contents of buf after nbd_pread and friends is unspecified on
error

=head2 Callbacks with C<int *error> parameter
Some of the high-level commands (L<nbd_pread_structured(3)>,

-the state machine at appropriate points in the server's reply before
-the overall command is complete. These callback functions, along with
-all of the completion callbacks, include a parameter C<error>
-containing the value of any error detected so far; if the callback
-function fails, it should assign back into C<error> and return C<-1>
-to change the resulting error of the overall command. Assignments
-into C<error> are ignored for any other return value; similarly,
-assigning C<0> into C<error> does not have an effect.

+C<error> containing the value of any error detected so far. If a
+callback function fails and wants to change the resulting error of the
+overall command visible later in the API sequence, it should assign
+back into C<error> and return C<-1>. Assignments into C<error> are
+ignored for any other return value; similarly, assigning C<0> into
+C<error> does not have an effect.
+
+Note that a mid-command callback might never be reached, such as if
+libnbd detects that the command was invalid to send (see
+L<nbd_set_strict_mode(3)>) or if the server reports a failure. It is
+safe for a mid-command callback to ignore non-zero C<error>: all the
+other parameters to the mid-command callback will still be valid
+(corresponding to the current portion of the server's reply), and the
+overall command will still fail (at the completion callback or
+L<nbd_aio_command_completed(3)> for an asynchronous command, or as the
+result of the overall synchronous command). Returing C<-1> from a
+mid-command callback does not prevent that callback from being reached
+again, if the server sends more mid-command replies that warrant
+another use of that callback. A mid-command callback may be reached
+more times than expected if the server is non-compliant.
+
+On the other hand, if a completion callback is supplied (only possible
+with asynchronous commands), it will always be reached exactly once,
+and the completion callback must not ignore the value of C<error>. In
+particular, the content of a buffer passed to L<nbd_aio_pread(3)> or
+L<nbd_aio_pread_structured(3)> is unspecified if C<error> is set on
+entry to the completion callback. It is recommended that if your code
+uses automatic command retirement, then the completion function should
+return C<1> on all control paths, even when handling errors (note that
+with automatic retirement, assigning into C<error> is pointless as
+there is no later API to see that value).

[libnbd PATCH 0/4] Work towards fixing nbdcopy silent corruption
by Eric Blake
These are the trivial patches modeled after Nir's commit 7ba6ef67,
fixing further places that fail to check *error during callbacks.
nbdcopy still has a bigger bug in that it is NOT properly checking for
*error in the pread/pwrite completion handlers, but fixing that
gracefully (rather than just quitting the process immediately, as we
can do in the examples), requires more invasive patches which I will
be posting separately for review, while the ones posted here are
trivial enough that I'm pushing them now (commits 23bcea4a..1373d423).
I also audited other uses of completion callbacks:
- in tests, closure-lifetimes, errors, server-death, and
shutdown-flags are all safe (either the callback returns 0 and the
code later calls nbd_aio_command_completed, or we are explicitly
testing aspects of completion callbacks)
- in fuse/operations.c, the completion callback returns 0 and calls
nbd_aio_command_completed later
- in examples/strict-structured-reads.c, the completion callback
properly checks *error
I also checked that nbdkit's nbd plugin properly checks *error.

[PATCH nbdkit] plugins: python: Add error example
by Nir Soffer
This plugin simulates errors in pread, pwrite, and extents. This is
useful for testing error handling in NBD clients, and understanding how
plugin exceptions are reported to the NBD client.
