[nbdkit PATCH 0/4] Allow plugins to disconnect a single client

by Eric Blake

nbdkit_shutdown() is a harsh hammer (it kills the entire server); sometimes in testing, it is more useful to disconnect just one client while keeping the server responsive to a reconnect request. Start this by implementing a new API and putting it to use in the blocksize-policy filter. I also have a pending libnbd series that plans to make use of this feature addition in its testsuite for proving a bug-fix for libnbd not obeying qemu's 32M block_maximum sizing constraints. Still to come as followup to this: Rich and I discussed on IRC how to extend the sh/eval plugins to allow rapid-prototype testing of requesting client disconnects. The idea we came up with was defining exit status 4 (nbdkit_shutdown), 5 (nbdkit_disconnect(true)), and 6 (nbdkit_disconnect(false)) as new recognized return values from the shell scriptlets. I'd probably also change the documentation to reserve return status 7-15 as currently undefined (right now, only 7 is undefined and 8-15 are currently documented as behaving the same as exit status 1). The chance of this affecting a real client of the sh or eval plugin is minimal.

[libnbd PATCH 0/3] Improve nbdsh -u handling

by Eric Blake

I was trying to add a TLS test to nbdkit, and got annoyed that I couldn't just write --run 'nbdsh -u "$uri" -c ...'. This fixes the libnbd side of the problem (a URI with ?tls-psk-file=... is rejected unless we tell libnbd that parsing local files is okay); but I will also be working on patches to nbdkit ($uri is more useful if it includes 'alice@' and '?tls-psk-file=...' in the first place). Eric Blake (3): nbdsh: Refactor handling of -u and friends nbdsh: Improve --help and initial banner contents. nbdsh: Allow -u interleaved with -c python/nbdsh.py | 142 +++++++++++++++++++++++++++------------------ sh/test-context.sh | 26 ++++----- sh/test-error.sh | 37 +++++++----- 3 files changed, 119 insertions(+), 86 deletions(-) -- 2.37.3

The RPM would have failed to build if the Python bindings had been ./configure-d out. The link shows libguestfs as "not build yet / Disabled": https://copr.fedorainfracloud.org/coprs/g/python/python-without-distutils... but then there's a build which succeeded: https://copr.fedorainfracloud.org/coprs/g/python/python-without-distutils... and it has Python bindings. (The logs of the build don't seem to be available.) Anyway I'll see if I can fix this upstream as requested.

Why cant't use the pie link option when compiling libgustfs

by guiHua

Hello，   When I compile libgustfs, it will throw exception: undefined reference to 'caml_local_roots' when adding pie link option.  Why is that? The command is like this: ./configure CFLAGS="-O2 -fPIC" LDFLAGS="-pie -Wl". I look forward to hearing from you.
