wic: fix calculation of partition number

2017-08-29T15:50:53+00:00

Total number of partitions should be taken into account when calculating real partition number for msdos partition table. The number can be different for the 4th partition: it can be 4 if there are 4 partitions in the table and 5 if there are more than 4 partitions in the table. In the latter case number 4 is occupied by extended partition.

wic: rewrite MBR disk identifier

2016-10-07T15:43:58+00:00

Disk identifier created by parted doesn't match the one we generated and used in bootloader config. We need to rewrite it to make our image bootable. Modified involved API and data structures to access previously generated disk identifiers after MBR is initialized. Written disk identifiers to MBR.

wic: generate PARTUUID for MDOS partitions

2016-10-07T15:43:58+00:00

Added generation of partition UUIDs for MSDOS partitions. UUID for MSDOS partitions is -, where disk identifier is a random 4 bytes long number. It's usually generated when MBR/partition table is initialized. As UUID is used to point to the root partition in bootloader config we need to generate it before the MBR is initialized. After MBR is created we need to rewrite system identifier to match it with what is used in bootloader config. This will be implemented in the next commit.

wic: implement --bmap option

2016-05-19T08:05:19+00:00

This option enables generation of .bmap file for the result image using native bmaptool. [YOCTO #9413] (From OE-Core rev: d64c7b37c40b052510419b4d6629b83319c833e4) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: use new syntax of 'except' statement

2016-05-14T22:05:13+00:00

New syntax 'except Exception as err' is supported by Python >= 2.7. Old syntax 'except Exception, err' is not supported by Python 3. Used new syntax to be able to run wic on Python 3.

wic: remove with_statement imports

2016-05-14T22:05:13+00:00

'with' statement is not used in baseimager.py It's supported by Python 2.7, which is included into all target distros. Other wic modules use this statement. Removed useless 'from __future__ import with_statement' from wic code. (From OE-Core rev: 528a1f20939589949831efbb4de6336776efe7d5) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: don't inherit classes from object

2016-05-14T22:05:13+00:00

All classes in Python3 are new style classes and don't need to be inherited from object. Wic code works fine without this inheritance even with Python2, so it's harmless to remove it.

wic: don't use dict.keys and dict.has_key

2016-05-14T22:05:13+00:00

Replaced calls of dict.keys and dict.has_key methods with the 'key in dict' statement. 'key in dict' is more pythonic, faster and readable. dict.has_key doesn't exist in Python 3.

wic: moved DiskImage to direct.py

2016-05-06T09:31:13+00:00

Moved DiskImage class from utils/fs_related.py to imager/direct.py as it's only used there. Removed fs_related module as it doesn't contain anything except of DiskImage. (From OE-Core rev: b3cc471790784c28f9362fcd6fc6a81c4316754c) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

Added new argument to add_partition call to pass partition system id down the stack. [YOCTO #9096] (From OE-Core rev: f2733df697192c0010c17b7bbb02f8679cb8f313) Signed-off-by: Ed Bartosh Signed-off-by: Ross Burton Signed-off-by: Richard Purdie
