wic/engine: use up all free space when expanding partitions

2018-07-29T23:02:52+00:00

Currently we just divide up the free space by the number of partitions that need to be re-sized. This leads to problems when a user has explicitly specified a subset of partitions (but not all) that need to re-sized along with the sizes. As an example, for an image with 3 partitions, if we use: wic write image.wic /dev/sdb --expand 1:10G This would lead to paritions 2 and 3 each being re-sized to one thirds of the free space instead of half. Change the behavior to use up all the free space.

wic/engine: fix errors when expanding partitions

2018-07-29T23:02:52+00:00

The UEFI spec implies that GPT partitions should be assumed to be on a 2048 sector boundary (for a 512 byte sector) and the current logic just divides the free sectors available by the number of partitions that need re-sizing, which may or may not align and the final result might overshoot the limits imposed after alignment. Since we are expanding already aligned partitions, just divide up the free space in multiples of 2048. Also use the exec_cmd wrapper instead of the subprocess call directly.

wic/engine.py: improve error message when required tools are missing

2018-07-02T10:41:25+00:00

Instead of showing that command 'None' was found, show the name of actual command that wasn't found on the host machine or at the native sysroot path provided by user.

wic: implement ext fs support for 'wic rm'

2017-09-11T16:30:28+00:00

Implemented removing files or directories from the ext partition using debugfs tool. (From OE-Core rev: be530b7c7beae6f9fc95eed245cb37066d56581e) Signed-off-by: Ed Bartosh Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

wic: implement ext fs support for 'wic cp'

2017-09-11T16:30:28+00:00

Implemented copying files to the ext partition using debugfs tool. (From OE-Core rev: 1a2bc70e6f85f414e7af48489e24c09ff335486d) Signed-off-by: Ed Bartosh Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

wic: implement ext fs support for 'wic ls'

2017-09-11T16:30:28+00:00

wic: always read image partitions

2017-08-27T21:30:07+00:00

Got rid of lazy evaluation of self.partitions property. It's not needed because partitions of the source image should be always read. (From OE-Core rev: 1186fd8fd4a4789dc7c60feb86cc9fdd03fee7b3) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: implement 'wic write' command

2017-08-27T21:30:07+00:00

This command writes image to the media or another file with the possibility to expand partitions to fill free target space. [YOCTO #11278] (From OE-Core rev: ac5fc0d691aad66ac01a5cde34c331c928e9e25a) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: extend list of used tools

2017-08-27T21:30:07+00:00

Added sfdisk, e2fsck, mkswap, resize2fs, mkdosfs to the list of used tools in Disk class. They're going to be used in 'wic write' implementation. Added dependency to util-linux to wic-tools to ensure that sfdisk and mkswap are available from wic-tools native sysroot.

wic: added 'fstypes' parameter to Disk.init

2017-08-27T21:30:07+00:00

This parameter specifies list of supported filesystems. So far only 'fat' is supported, but 'wic write' is going to support at least 'fat', 'ext' and 'swap'. (From OE-Core rev: 7cffcdcfdf4f8934d212740a6d7cf136911ebdac) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie
