Similar to C, OCaml and Rust, this is not a plugin per se. Instead it's more of a method and set of tests around writing plugins in golang. They are standalone programs that compile into shared objects that nbdkit can then load (so there is no "go plugin" between nbdkit and the user plugin, unlike in scripting languages like Perl). --- plugins/golang/nbdkit-golang-plugin.pod | 34 ++++++++ configure.ac...

Sorry Dan, but I really do dislike golang with a passion :-) Here is a patch that allows you to write nbdkit plugins in golang. As with C, OCaml and Rust, you can write a plugin in Go which compiles directly to a .so file that can be loaded into golang, so in that sense it works completely differently from scripting language plugins like...

Thanks: Dan Berrangé XXX UNFINISHED: - Is using uintptr for the handle a good idea? Plugins must return something != 0. In other languages we would allow plugins to return an arbitrary object here, but this is not possible in golang because of lack of GC roots. - Default can_* methods are hard to implement. Ideally we would be able to test if a user plugin implements a particular callback (eg. TestPlugin.PWrite) or else defaults to the default callback, but even with reflection I don't think this is possible...

For the current set of examples this doesn't matter. This also adds another example where we use the Connection to store data, just to check that actually works.

These bindings get as far as running very simple connections. However there are many missing parts still: * No callbacks. * No functions which handle buffers (pread/pwrite!) This is posted just for general early interest, not even for review. Rich.

...s. Instead we can set PKG_CONFIG to point to a fake pkg-config binary which will return the correct CFLAGS.

This feature is roughly finished now, although it needs a few more tests and some examples. It's pretty much up to par with all the other bindings, but it lacks a completely safe AIO buffer. It won't stop you from freeing the buffer too early) because golang's GC inexplicably lacks a way to declare a root from C. I can probably do it with a global variable and ref counting on the golang side, but ... really?

Now that we have a distinct branch in the generator when returning an enum or bitmask that cannot fail, we can use it in Golang for symmetry, so that the result of a get function can be plugged into a set function without a trip through other types. --- generator/GoLang.ml | 12 ++++++------ .../libnbd/libnbd_110_defaults_test.go | 6 +++--- .../libnbd/libnbd_120_set_non_defa...

Hello. I'm very happy with libguestfs, but now i'm try to write packer plugin to strip images: 1) resize filesystem to minimum 2) resize partitions to minimum 3) create/resize file with needed size But golang binding have not docs. Is that possible to generate something suitable to godoc.org to determine api methods and input,output variables for functions? -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru

Now runs a complete set of tests, notably including the AIO test. File descriptors are passed in and out as plain ints (instead of *os.File) for a couple of reasons: (1) We have to pass the plain int to syscall.Select. (2) Turning an fd into an os.File causes golang to set the blocking flag which is deeply unhelpful. Rich.
