I'm still working my way through the filters before this series will be complete, but this is enough of a start to at least get some feedback on the idea of implementing another NBD protocol extension.

Rich pointed out that making thread_model dynamic even for plugins makes some sense, so here is the code for doing it for 'sh'. I'm less confident on how to do it for OCaml and Rust (not to mention that those allow the plugin to already compile in their model, rather than the language binding glue forcing a model). The other languages (lua, perl, python, ruby) still need to be

Some feature additions to the shell script plugin allow us to test the export flags field reasonably easily. Rich.

I have activerecord-sybase-adapter installed -- and Sybase itself, so I have the drivers. In irb or in the rails console, this works: ActiveRecord::Base.establish_connection( :adapter => “sybase”, :database => “mydb”, :host => “myhost”, :myport => myport, :username => “read_only”, :password => “read_only”) In Rails, I have this in my database.yml: pacs: adapter: sybase database: mydb username: read_only password: read_only host: myhost port: myport And then I have the following model: class PacsPatient < ActiveRecord::Base establish_connection "...

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that

v1 was here: https://www.redhat.com/archives/libguestfs/2018-December/thread.html#00123 v2: - Document "-" instead of "script=-" and use it in the test; and verify this also works on FreeBSD; and verify that it doesn't depend on the particular behaviour of our wrapper script and should work with installed nbdkit too. - Fix handling of zero flags parameter. -
