[PATCH 0/2] Skip test-qemu-drive-libvirt.sh if libvirt is < 1.1.3

by Pino Toscano

Hi, test-qemu-drive-libvirt.sh fails to run with libvirt < 1.1.3, because the <test:runstate> attribute (used to keep the domains shut off) has been introduced in that libvirt version. Create a small (uninstalled) C tool which just does this version check, to be used in all the tests (just one, so far) written in shell/scripting language.

[PATCH INCOMPLETE] Rewrite virt-make-fs in C (originally Perl).

by Richard W.M. Jones

I thought it would be easy to rewrite virt-make-fs in C. Two days later ... The Perl program uses a lot of external commands, which makes it pretty tedious to implement in C. Rich.

[PATCH] fuse: In mount-local-run, test if root filesystem has been mounted (RHBZ#1057504).

by Richard W.M. Jones

It is never normally valid to use the mount-local* APIs when you haven't mounted some filesystems in the libguestfs namespace. If you try it, it results in some odd errors. The mount-local-run call is successful, but subsequent operations fail: $ mkdir -p /tmp/mnt $ guestfish -x -N fs mount-local /tmp/mnt : mount-local-run libguestfs: error: lstat: lstat_stub: you must call 'mount' first to mount the root filesystem libguestfs: error: lstat: lstat_stub: you must call 'mount' first to mount the root filesystem With this commit, the mount-local-run call gives an error. The error is implemented by calling guestfs_exists (g, "/") which has the side effect of running the NEED_ROOT macro in the daemon. (There is no simple equivalent of NEED_ROOT on the library side.) --- src/fuse.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/fuse.c b/src/fuse.c index dd4f139..c22cbba 100644 --- a/src/fuse.c +++ b/src/fuse.c @@ -1028,6 +1028,12 @@ guestfs__mount_local_run (guestfs_h *g) return -1; } + /* Test if root is mounted.

[PATCH] builder: read all the available notes from the index

by Pino Toscano

Switch the internal storage for the notes of each entry to a sorted list with all the subkeys available (which should represent the translations to various languages). The current outputs are the same (i.e. still the untranslated notes), so this is just internal refactoring/preparation. --- builder/builder.ml | 4 ++-- builder/index_parser.ml | 19 +++++++++++++++---- builder/index_parser.mli | 2 +- builder/list_entries.ml | 10 +++++++--- 4 files changed, 25 insertions(+), 10 deletions(-) diff --git a/builder/builder.ml b/builder/builder.ml index bb0b108..19d1e42 100644 --- a/builder/builder.ml +++ b/builder/builder.ml @@ -200,9 +200,9 @@ let main () = (match mode with | `Notes -> (* --notes *) (match entry with - | { Index_parser.notes = Some notes } -> + | { Index_parser.notes = ("", notes) :: _ } -> print_endline notes; - | { Index_parser.notes = None } -> + | { Index_parser.notes = _ } -> printf (f_"There are no notes for %s\n") arg ); exit 0 diff --git a/builder/index_parser.ml b/builder/index_parser.ml index da44b21..961b91b 100644 --- a/builder/index_parser.ml +++ b/builder/index_parser.ml @@ -35,7 +35,7 @@ and entry = { compressed_size : int64 option; expand : string option; lvexpand : string option; - notes : string option; + notes : (string * string) list; hidden : bool; sigchecker : Sigchecker.t; @@ -92,8 +92,8 @@ let print_entry chan (name, { printable_name = printable_name; | Some lvexpand -> fp "lvexpand=%s\n" lvexpand ); (match notes with - | None -> () - | Some notes -> fp "notes=%s\n" notes + | ("", notes) :: _ -> fp "notes=%s\n" notes + | _ -> () ); if hidden then fp "hidden=true\n" @@ -219,7 +219,18 @@ let get_index ~prog ~debug ~downloader ~sigchecker source = let lvexpand = try Some (List.assoc ("lvexpand", None) fields) with Not_found -> None in let notes = - try Some (List.assoc ("notes", None) fields) with Not_found -> None in + let rec loop = function + | [] -> [] + | (("notes", subkey), value) :: xs -> + let subkey = match subkey with + | None -> "" + | Some v -> v in + (subkey, value) :: loop xs + | _ :: xs -> loop xs in + List.sort ( + fun (k1, _) (k2, _) -> + String.compare k1 k2 + ) (loop fields) in let hidden = try bool_of_string (List.assoc ("hidden", None) fields) with diff --git a/builder/index_parser.mli b/builder/index_parser.mli index 54f1807..3c679b3 100644 --- a/builder/index_parser.mli +++ b/builder/index_parser.mli @@ -29,7 +29,7 @@ and entry = { compressed_size : int64 option; expand : string option; lvexpand : string option; - notes : string option; + notes : (string * string) list; hidden : bool; sigchecker : Sigchecker.t; diff --git a/builder/list_entries.ml b/builder/list_entries.ml index 7369e6c..742e43b 100644 --- a/builder/list_entries.ml +++ b/builder/list_entries.ml @@ -71,10 +71,10 @@ and list_entries_long ~sources index = printf "%-24s %s\n" (s_"Download size:") (human_size size); ); (match notes with - | None -> () - | Some notes -> + | ("", notes) :: _ -> printf "\n"; printf (f_"Notes:\n\n%s\n") notes + | _ -> () ); printf "\n" ) @@ -108,6 +108,10 @@ and list_entries_json ~sources index = | None -> () | Some n -> printf " \"%s\": \"%Ld\",\n" key n in + let print_notes = function + | ("", notes) :: _ -> + printf " \"notes\": \"%s\",\n" (json_string_escape notes) + | _ -> () in printf "{\n"; printf " \"version\": %d,\n" 1; @@ -132,7 +136,7 @@ and list_entries_json ~sources index = json_optional_printf_string "full-name" printable_name; printf " \"size\": %Ld,\n" size; json_optional_printf_int64 "compressed-size" compressed_size; - json_optional_printf_string "notes" notes; + print_notes notes; printf " \"hidden\": %s\n" (json_string_of_bool hidden); printf " }%s\n" (trailing_comma i (List.length index)) ) index; -- 1.8.3.1

[PATCH 0/7] Various fixes for Ceph drives and parsing libvirt XML.

by Richard W.M. Jones

Miscellaneous fixes to: - Handling of Ceph drives now works end-to-end (RHBZ#1026688). - In particular, you can now use rbd:/// URIs in guestfish (and they work). - Parse Ceph & NBD network drives from libvirt XML correctly, so that existing domains with Ceph/NBD drives can be added (eg. using guestfish -d option). - Add more testing of the above.
