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 libguestfs functions return can be a *GuestfsError, but the function signature should have (<val>, error)...

This patch is easier to read if you use the 'git show -w' option. Also observe that: fun a -> ( fun () -> (* code *) ) (ie. returning a closure) is identical to: fun a () -> (* code *) Rich.

...oes then closes it) and before blockdev_rereadpt The fix is to run udev_settle *before* all blockdev, parted and sfdisk commands. Note we do it before because at this point a blkid command may be running which we have to wait for. None of these commands should be performance sensitive (unlike pwrite_device, where I have removed the udev_settle call). In the parted and sfdisk cases we also have to run this command afterwards, since parted itself will have closed the block device. There may be alternatives to this patch: - Add a udev rule (temporarily?) which causes udev to ignore devices that...

OCaml 4.02 introduced the 'bytes' type, a mutable string intended to replace the existing 'string' type for those cases where the byte array can be mutated. In future the 'string' type will become immutable. This is not the default now, but it can be forced using the '-safe-string' compile option. I tested this on Fedora 24 (OCaml 4.02) & RHEL 7 (OCaml 4.01).

I'm currently working on gobject bindings for libguestfs. I haven't got as far as compiling anything yet, but I've attached the C header for initial review.

This still isn't working at the moment. See: http://marc.info/?t=139457409300003&r=1&w=2 This set of patches: - Adds new APIs to support discard in libguestfs. - Adds discard support to virt-format. - Adds discard support to virt-sysprep. - Implements virt-sparsify --in-place. Rich.

Version 1 of the patch, for discussion, but not to be applied. It does work, but needs a lot more testing. This removes all the psychopathic gettextify cruft, and replaces it with a 99 line Makefile.am. A large win, I think. The third patch implements gettext support in the OCaml tools. The fourth patch is just for illustration. It shows the consequent changes to libguestfs.pot and the po
