...it returns an array containing consecutive stat structs (not pointers). Changing the return type of guestfs_stat would break API. Changing the generator to support symbol versioning is judged to be too intrusive. Therefore this adds a new struct (guestfs_statns) and new APIs: guestfs_statns guestfs_lstatns guestfs_lstatnslist which return the new struct (or array of structs in the last case). The old APIs may of course still be used, forever, but are deprecated and shouldn't be used in new programs. Because virt tools are compiled with -DGUESTFS_WARN_DEPRECATED=1, I have updated all the pla...

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

Miscellaneous refactoring, but the main one is to rename mllib/ as common/mltools/ Rich.

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

Very large but mechanical change to the generator. Rich.

Split up the huge generator/actions.ml into several smaller files. Rich.
