wic: make engine.py:get_partitions() resilient to parted/dmidecode stderr output

2018-10-12T15:57:21+00:00

Running wic commands on Debian 10 systems fail in scripts/lib/wic/engine.py:get_partitions() due to new stderr output captured when trying to parse the output from /sbin/parted as a non-root user. The parted command calls the dmidecode utility, which produces this error as a non-root user: /sys/firmware/dmi/tables/smbios_entry_point: Permission denied /dev/mem: Permission denied scripts/lib/wic/engine.py:get_partitions() calls misc.py:exec_cmd(), a subprocess wrapper which returns a combined stderr and sdtdout. These messages to stderr confuse the partition table parser in get_partitions(). This patch has the partition table parser ignore lines before the expected "BYT;" header string. Running wic in Debian 9 does not have this issue. (From OE-Core rev: d6936301d7598b7a783beaae95109555faf6cc17) Signed-off-by: Geoff Parker Signed-off-by: Richard Purdie

wic/engine: improve error reporting when using rm with wic

2018-07-26T12:16:40+00:00

When trying to delete something from an ext partition using debugfs, we don't show any error to the user when that operation fails. Change this behavior to show the error generated by debugfs. Also, fallback to use rmdir in case we are trying to delete a directory. However, unlike mdeltree that is used for a FAT partition, there's no easy way to delete a non empty directory. Show an error instead when that happens so user can take appropriate action.

logging: use warning instead warn

2018-07-26T12:16:40+00:00

The warn method is deprecated. We should use the documented warning instead. Quoting from the python's official doc: """ Note: There is an obsolete method warn which is functionally identical to warning. As warn is deprecated, please do not use it - use warning instead.

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

2018-07-18T09:18:42+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. (From OE-Core rev: a88f1b5d88dbc5fb28be24b9787d73b9e0cdf183) Signed-off-by: Anuj Mittal Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

wic/engine: fix errors when expanding partitions

2018-07-18T09:18:42+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.

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. (From OE-Core rev: 3157ebb131e01e74689b1f87a35278350f315e7d) Signed-off-by: Anuj Mittal Signed-off-by: Richard Purdie
