It's not necessary to store the label in the context type, instead use
the corresponding library function to get the current in-memory label
container.
The device label information is stored in-memory by libfdisk library
when creating a context or assigning a device.
Avoids possible incosistencies between libfdisk in-memory label and
python-libfdisk context type label information.

|
|
|
|
|
|
|

Allows creation of a context object or device assign if no label
is present in the device.
This case is not frecuent but not critical, do not raise an exception.
For example, a brand new disk with no label or a raw virtual disk
image with no label.

Some of python-libfdisk is inspired by the python bindings of libmount
(from util-linux project).
Remove a comment from pylibmount that slipped into python-libfdisk

python-libfdisk raises Python exceptions when the libfdisk reports an
error when executing some function. libfdisk returns negative
errno values when reporting some error.
Adds utility function to set PyErr string based on the strerror of
a given errno code. Useful when raising Python exceptions.

libfdisk context add_partition function initializes a passed argument
with the new partition's partno.
If add_partition is successful, return its partno.

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 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>

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

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.

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>

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.

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.

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.

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.

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.

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'
