wic/filemap: Fall back to standard copy when no way to get the block map

2020-07-18T10:06:31+00:00

For some filesystems, such as aufs which may be used by docker container, don't support either the SEEK_DATA/HOLE or FIEMAP to get the block map. So add a FileNobmap class to fall back to standard copy when there is no way to get the block map.

wic/filemap: If FIGETBSZ iotctl fail, failback to os.stat

2020-01-02T16:39:13+00:00

Some file systems don't support fetching the block size (notably the file system Docker uses for containers), so if iotctl() fail, try to use failback via os.stat() to get block size.

wic/filemap: handle FIGETBSZ failing

2019-06-08T15:01:41+00:00

Some file systems don't support fetching the block size (notably the file system Docker uses for containers), so handle the iotctl() failing and raise the expected error. (From OE-Core rev: 3757073726a00c5250556aae3d0daac76b88085e) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

meta/lib+scripts: Convert to SPDX license headers

2019-05-09T15:31:55+00:00

This adds SPDX license headers in place of the wide assortment of things currently in our script headers. We default to GPL-2.0-only except for the oeqa code where it was clearly submitted and marked as MIT on the most part or some scripts which had the "or later" GPL versioning. The patch also drops other obsolete bits of file headers where they were encoountered such as editor modelines, obsolete maintainer information or the phrase "All rights reserved" which is now obsolete and not required in copyright headers (in this case its actually confusing for licensing as all rights were not reserved). More work is needed for OE-Core but this takes care of the bulk of the scripts and meta/lib directories. The top level LICENSE files are tweaked to match the new structure and the SPDX naming.

wic: use explicit errno import

2018-11-07T23:08:55+00:00

os.errno doesn't work in Python 3.7 and shouldn't have ever worked, so use import errno explicitly. (From OE-Core rev: 82f9157e84dcaf0ad4292053b09be68c2290d197) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

wic: if we can't get from ioctl, try from os.stat()

2018-01-14T09:11:57+00:00

Under some conditions, ioctl FIGETBSZ can't return real value. We can try to use fallback via os.stat() to get block size.

filemap: calculate dst size correctly

2017-06-14T09:18:29+00:00

Fixed calculation of the dst file size using skip, seek and length parameters. Current code does it incorrectly which causes sparse_copy API to create unnecessary big output files. (From OE-Core rev: e6d709a6382e4b913612f597e66ad07b0e351d5f) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie
