uuid: 'fat-uuid->string' preserves leading zeros.

2019-05-07T10:18:44Z

Fixes . Reported by sirgazil . Previously, leading zeros would be removed, leading to an "invalid" UUID: (uuid->string (uuid "00CA-050E" 'fat32)) ⇒ "CA-50E" (string->uuid "CA-50E" 'fat32) ⇒ #f * gnu/system/uuid.scm (fat-uuid->string): Pad digits with zeros. * tests/uuid.scm ("uuid, FAT32, leading zeros preserved"): New test.

uuid: 'uuid' returns #f when 'string->uuid' returns #f.

* gnu/system/uuid.scm (uuid): When STR is not a literal, return #f when 'string->uuid' returns #f. * tests/uuid.scm ("uuid, dynamic value"): New test.

Conceptually a UUID is just a bytevector. However, there's software out there such as GRUB that relies on the string representation of different UUID types (e.g., the string representation of DCE UUIDs differs from that of ISO-9660 UUIDs, even if they are actually bytevectors of the same length). This new record type allows us to preserve information about the type of UUID so we can eventually convert it to a string using the right representation. * gnu/system/uuid.scm (): New record type. (bytevector->uuid): New procedure. (uuid): Return calls to 'make-uuid'. (uuid->string): Rewrite using 'match-lambda*' to accept a single 'uuid?' argument. * gnu/bootloader/grub.scm (grub-root-search): Check for 'uuid?' instead of 'bytevector?'. * gnu/system.scm (bootable-kernel-arguments): Check whether ROOT-DEVICE is 'uuid?'. (read-boot-parameters): Use 'bytevector->uuid' when the store device is a bytevector. (read-boot-parameters-file): Check for 'uuid?' instead of 'bytevector?'. (device->sexp): New procedure. (operating-system-boot-parameters-file): Use it for 'root-device' and 'store'. (operating-system-bootcfg): Remove conditional in definition of 'root-device'. * gnu/system/file-systems.scm (file-system->spec): Check for 'uuid?' on DEVICE and take its bytevector. * gnu/system/mapped-devices.scm (open-luks-device): Likewise. * gnu/system/vm.scm (iso9660-image): Call 'uuid-bytevector' for the #:volume-uuid argument.

file-systems: Introduce (gnu system uuid).
