* New API: guestfs_shutdown: Cleanly shutdown the backend.Richard W.M. Jones2012-07-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The new API splits orderly close into a two-step process: if (guestfs_shutdown (g) == -1) { /* handle the error, eg. qemu error */ } guestfs_close (g); Note that the explicit shutdown step is only necessary in the case where you have made changes to the disk image and want to handle write errors. Read the documentation for further information. This change also: - deprecates guestfs_kill_subprocess - turns guestfs_kill_subprocess into the same as guestfs_shutdown - changes guestfish and other tools to call shutdown + close where necessary (not for read-only tools) - updates documentation - updates examples (cherry picked from commit ffbf1475f7ae7c462db289ad4834391469e72edd)
* Fix strict-overflow bugs and reenable this warning.Richard W.M. Jones2012-03-131-1/+1
| | | | | | | | | In two places, we were counting things in an array using an 'int'. In theory, the int could overflow, so gcc determines this to be undefined behaviour. The fix is to use size_t or ssize_t instead. (cherry picked from commit d66dd2260c724bdfe57a8595aac37c8e9173cee5)
