This adds a new nbdkit_shutdown() API whereby plugins and filters can request that the server shuts down (asynchronously) during the serving phase. Two new filters are added, one of which depends on this feature and the other not needing it but being somewhat related. Rich.

This incomplete patch adds a new filter allowing more control over when nbdkit exits. You can now get nbdkit to exit gracefully on certain events, such as a file being created, a pipe held open by another process going away, or when another PID exits. There is also a script option to allow for completely custom events. It is untested at the moment, I'm posting it to get feedback on the

This is a second version of the limit filter. v1 was posted here: https://www.redhat.com/archives/libguestfs/2020-March/msg00015.html I didn't bother to repost the other three patches because they are the same. The difference is this version of the filter takes security more seriously. It shouldn't be possible for malicious clients to connect more than limit=N times to the plugin now,

Here's changes to the file plugin (which I'm happy with) and a new exportname filter (which is still at RFC stage; I need to finish implementing strict mode in .open, and add tests). I also discovered that we really want .list_exports and .open to know when they are used on plaintext vs. tls clients for --tls=on, and we may want to split out a new .default_export callback rather than

This creates libnbdkit.so as discussed in the following thread: https://www.redhat.com/archives/libguestfs/2020-March/thread.html#00203 test-delay-shutdown.sh fails for unclear reasons. This series starts by reverting "tests: Don't strand hung nbdkit processes" which is because several other tests fail randomly unless I revert this patch. I didn't investigate this yet so it
