It's a serious design

Go 1.17 or newer is required to use unsafe.Slice(), which in turn allows us to write a simpler conversion from a C array to a Go object during callbacks. To check if this makes sense, look at https://repology.org/project/go/versions compared to our list in ci/manifest.yml, at the time I made this commit: Alpine 3.15: 1.17.10 AlmaLinux 8: 1.19.10 CentOS Stream 8: 1.20.4 Debian 10: 1.11.6 Debian

Commit 6725fa0e12 changed copy_uint32_array() to utilize a Go hack for accessing a C array as a Go slice in order to potentially benefit from any optimizations in Go's copy() for bulk transfer of memory over naive one-at-a-time iteration. But that commit also acknowledged that no benchmark timings were performed, which would have been useful to demonstrat an actual benefit for using hack in

Go API functions returned (<val>, *GuestfsError) that made code like this fail to build: n, err := os.Stdin.Read(buf) if err != nil { log.Fatal(err) } n, err = g.Pwrite_device(dev, buf[:n], off) ... As err should be of error (interface) type as of the stdlib call, and should be of *GuestfsError type as of the libguestfs call. The concrete error value that

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 Perl and Python where there's an

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:

Hi, i cannot import libguestfs golang lib, go get package libguestfs.org/guestfs: unrecognized import path " libguestfs.org/guestfs" (https fetch: Get https://libguestfs.org/guestfs?go-get=1: dial tcp [2001:41c9:1:422::215]:443: getsockopt: connection refused) Any ideas? has the url changed or something? @rwmjones -- Regards, Shashwat Shagun

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

Hi, I would like to create a golang binding for xapian. Has anyone made the necessary swig files for it? If not can someone who has experience with swig offer tips or ready-made files? Cheers, Marius PS1: A sample of how the binding will be used: https://gist.github.com/mtibeica/7d2c680046b4bd0da751#file-quickstart-go PS2: I wrote the nodejs binding for xapian (found on
