The existing APIs guestfs_stat, guestfs_lstat and guestfs_lstatlist return a stat structure that contains atime, mtime and ctime fields that store only the timestamp in seconds. Modern filesystems can store timestamps down to nanosecond granularity, and the ordinary glibc stat(2) wrapper will return these in "hidden" stat fields:...

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

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that

This changes the proposed API slightly. Previously 'mount-local' generating a 'mounted' event when the filesystem was ready, and from the 'mounted' event you had to effectively do a fork. Now, 'mount-local' just initializes the mountpoint and you have to call 'mount-local-run' to enter the FUSE main loop. Between these calls you can do a fork or whatever

Since there are deprecated APIs, make sure that users notice they are deprecated in more prominent ways than done so far: - using deprecated C functions now warns by default - it is possible to use the C library making sure no deprecated function is ever used - Python/Ruby/Perl scripts now get warning messages (configured according to their own systems) when deprecated functions are used The

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be
