[Libguestfs] [PATCH v3 1/3] daemon: make sgdisk_info_extract_uuid_field more generic

Rename the sgdisk_info_extract_uuid_field to sgdisk_info_extract_field in order to reuse it for other field types. Just like its C ancestor, it now needs an extractor function to be passed as parameter. --- daemon/parted.ml | 22 ++++++++++++---------- 1 file changed, 12 insertions(+), 10 deletions(-) diff --git a/daemon/parted.ml b/daemon/parted.ml index d6638867a..6fe803613 100644 --- a/daemon/parted.ml +++ b/daemon/parted.ml @@ -124,12 +124,11 @@ let part_get_parttype device = | _ -> failwithf "%s: cannot parse the output of parted" device -let rec part_get_gpt_type device partnum = - sgdisk_info_extract_uuid_field device partnum "Partition GUID code" -and part_get_gpt_guid device partnum = - sgdisk_info_extract_uuid_field device partnum "Partition unique GUID" +let extract_guid value = + (* The value contains only valid GUID characters. *) + String.sub value 0 (String.span value "-0123456789ABCDEF") -and sgdisk_info_extract_uuid_field device partnum field = +let sgdisk_info_extract_field device partnum field extractor = if partnum <= 0 then failwith "partition number must be >= 1"; udev_settle (); @@ -167,13 +166,16 @@ and sgdisk_info_extract_uuid_field device partnum field = (* Skip any whitespace after the colon. *) let value = String.triml value in - (* Extract the UUID. *) - extract_uuid value + (* Extract the value. *) + extractor value | _ :: lines -> loop lines in loop lines -and extract_uuid value = - (* The value contains only valid GUID characters. *) - String.sub value 0 (String.span value "-0123456789ABCDEF") +let rec part_get_gpt_type device partnum = + sgdisk_info_extract_field device partnum "Partition GUID code" + extract_guid +and part_get_gpt_guid device partnum = + sgdisk_info_extract_field device partnum "Partition unique GUID" + extract_guid -- 2.15.1
