* context: add_partition returns partnoJose M. Guisado2022-12-151-3/+4
| | | | | | | libfdisk context add_partition function initializes a passed argument with the new partition's partno. If add_partition is successful, return its partno.
* partition: add partition type getsetJose M. Guisado2022-12-151-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | Partition type getset enables modifying and getting the type of a give libfdisk partition. The type of a partition is defined using PartType, which can only be instanced via label specific functions get_parttype_from_string or get_parttype_from_code. For example, to set the type of a new partitions to 'EFI System': >>> import fdisk >>> pa = fdisk.Partition() >>> pa.type >>> cxt = fdisk.Context('./disk.bin', readonly=False) >>> cxt.create_disklabel('gpt') >>> efitype = cxt.label.get_parttype_from_string("c12a7328-f81f-11d2-ba4b-00a0c93ec93b") >>> pa.type = efitype Following the previous example, getting its current partition type: >>> pa.type <libfdisk.PartType object at 0x7f2f0a9a12d0, name=EFI System>
* parttype: add parttype class and functionsJose M. Guisado2022-12-155-1/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parttype is a container for partition types in libfdisk. In python-libfdisk, the only way to create parttype instances is using the corresponding label-specific function: get_parttype_from_{code,string} This function wraps libfdisk's label_get_parttype_from_code (lookup DOS label parttype by hex code) and label_get_parttype_from_string (lookup GPT parttype by type uuid) For example, to get the parttype instance of 'EFI System' partition type of a GPT label, with type uuid 'c12a7328-f81f-11d2-ba4b-00a0c93ec93b': >>> import fdisk >>> cxt = fdisk.Context('./disk.bin', readonly=False) >>> cxt.create_disklabel('gpt') >>> efitype = cxt.label.get_parttype_from_string("c12a7328-f81f-11d2-ba4b-00a0c93ec93b") >>> efitype <libfdisk.PartType object at 0x7f503e4a5270, name=EFI System> See: https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Partition-types.html https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Label.html#fdisk-label-get-parttype-from-code https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Label.html#fdisk-label-get-parttype-from-string
* partition: add *_follow_default optional paramsJose M. Guisado2022-12-151-9/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add optional parameters inside init function of partition. Optional parameters refer to: - partno_follow_default - start_follow_default - end_follow_default These options can be used in order to enable or disable default partno, start and end value when adding partitions. With those optional parameters enabled by default a user is able to add a partition into the context label without specifying any attribute. >>> import fdisk >>> cxt = fdisk.Context('./disk.bin', readonly=False) >>> cxt.create_disklabel('gpt') >>> pa = fdisk.Partition() >>> cxt.add_partition(pa) This enables: - "Filling" the rest of the disk with last partition - No need to track start/end sector for any following partition - No need to track next partno number for any following partition See: https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Partition.html#fdisk-partition-partno-follow-default https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Partition.html#fdisk-partition-start-follow-default https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Partition.html#fdisk-partition-end-follow-default
* context: add add_partition methodJose M. Guisado2022-12-152-0/+27
| | | | | | | | This method wraps fdisk_add_partition. Allows modifying in-memory partition table of a given context. Remember that changes need to be written to disk using the relevant fdisk_write_disklabel function wrapper.
* partition: add partno setterJose M. Guisado2022-12-151-4/+57
| | | | | | | | | | | | | | | | | Allows changing in-memory partno field of a Partition instance: >>> import fdisk >>> pa = fdisk.Partition() >>> pa.partno = 3 >>> pa <libfdisk.Partition object at 0x7f4603a38f30, partno=3> If partno is unset repr shows 'None': >>> import fdisk >>> pa = fdisk.Partition() >>> pa <libfdisk.Partition object at 0x7f86c4338f30, partno=None>
* partition: return None if partno is unsetJose M. Guisado2022-12-151-2/+1
| | | | | | | Undefined values in libfdisk should map to None type in Python. Py_BuildValue("%d", -1); is also incorrectly formatted and raises an error when executed.
* context: add disklabel creation and writingJose M. Guisado2022-12-151-0/+36
| | | | | | | | | Adds wrappers for following label related functions from libfdisk: - fdisk_create_disklabel - fdisk_write_disklabel These functions are declared as methods of a Context python object.
* context: rename set_size_unit variablesJose M. Guisado2022-12-151-3/+3
| | | | | | Renames 'cval' to 'szunit' for better readability. This variable is used to store the size_unit constant that is going to be set using fdisk_set_size_unit.
* context: add readonly parameterJose M. Guisado2022-12-151-10/+11
| | | | | | | | fdisk_assign_device() contains 'readonly' parameter to indicate how to open the device. Assigned device 'readonly' must be false (0) in order to write in-memory changes to it.
* context: add size_unit getsetJose M. Guisado Gomez2022-06-071-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | Size unit can be get or set using 'size_unit' context member. >>> for pa in cxt.partitions: ... cxt.partition_to_string(pa, fdisk.FDISK_FIELD_SIZE) ... '114.6G' >>> cxt.size_unit 0 >>> cxt.size_unit == fdisk.FDISK_SIZEUNIT_HUMAN True >>> cxt.size_unit = fdisk.FDISK_SIZEUNIT_BYTES >>> for pa in cxt.partitions: ... cxt.partition_to_string(pa, fdisk.FDISK_FIELD_SIZE) ... '123010531328' Use fdisk_get_size_unit to get size unit value. https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Context.html#fdisk-get-size-unit Use fdisk_set_size_unit to set size unit value. https://cdn.kernel.org/pub/linux/utils/util-linux/v2.34/libfdisk-docs/libfdisk-Context.html#fdisk-set-size-unit

* fdisk.c: add partition module objectJose M. Guisado Gomez2022-04-262-0/+2
| | | | | | | | | | | | | | | | Call Partition_AddModuleObject when initializing the python module. Fixes bug when using the Partition class but the class has not been added to the module via Py_TypeReady. A common error was the type not being ready (missing attributes): >>> for pa in cxt.parts: ... print(pa.partno) ... Traceback (most recent call last): File "<stdin>", line 2, in <module> AttributeError: 'libfdisk.Partition' object has no attribute 'partno'
