similar to: NOTE: Relaunching handles (don't do it!)

I saw the latest parrot release notice on LWN this week and randomly wondered the Perl6 native call interface was like compared to the horrific mess that is Perl5 XS. The answer is that it is a thing of beauty ! Here is the libguestfs hello world example in Perl6 $ dd if=/dev/zero of=guest.img bs=1M count=100 $ mke2fs guest.img $ cat guestfs.p6 use NativeCall; say "Defining stubs";

Rename the existing tests according to the naming/numbering described in guestfs-hacking(1), and improve the current ones: - guestfs_php_001.phpt: rename to guestfs_020_create.phpt - guestfs_php_003.phpt: rename to guestfs_070_optargs.phpt - guestfs_php_bindtests.phpt: rename to guestfs_090_bindtests.phpt - guestfs_091_version.phpt: new, checks taken from the former guestfs_php_002.phpt -

libguestfs recently added support for virtio-scsi and libvirt, and when these are both available this lets us relatively easily add hotplugging of drives. This email is about how we would present that through the libguestfs API. (a) The current API Currently you have to add drive(s) via guestfs_add_drive* and then call guestfs_launch, ie. your program must look something like this: guestfs_h

There's a new syntax check rule from gnulib. It requires that you write e.g., exit (EXIT_SUCCESS), not exit (0). And the same for 1/EXIT_FAILURE and any other constants. There were a lot of violations, including a few false positives, so I started with the exemptions (see the .x-sc file below). Then I converted the vast majority automatically, with this: maint: use EXIT_SUCCESS and

Well, I get these error messages during the execution of guestfs_mount_local_run(). What can I do then ? On Wed, Jul 17, 2013 at 5:08 PM, Richard W.M.

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

Like with the previous commit, this replaces instances of: if (something_bad) { fprintf (stderr, "%s: error message\n", guestfs_int_program_name); exit (EXIT_FAILURE); } with: if (something_bad) error (EXIT_FAILURE, 0, "error message"); (except in a few cases were errno was incorrectly being ignored, in which case I have fixed that). It's slightly

--autosysroot option uses suggestions to user on how to mount filesystems and change root suggested by --suggest option in virt-rescue. Commands are passed on kernel command line in format guestfs_command=command;. Command ends with a semicolon and there can be multiple commands specified. These are executed just before bash starts. On successfull run user is presented directly with bash in

This can be used for creating temporary disks to thin clients, as a kind of "remote tmpfs".

Replace the monolithic 'test-max-disks.pl' script with a test program written in C. The program is completely equivalent to the old script, except for the enhancement that it is able to detect if disks are added to the appliance in the wrong order. The tests themselves are split out into some shell scripts: - test-27-disks: Fully tests 27 disks. This is the minimum supported
