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.

wic: code cleanup

2017-06-23T10:44:12+00:00

Split long lines. Removed unused imports. (From OE-Core rev: 49b704864c7db49e41a0b6bbdb8a2840e7fa232b) Signed-off-by: Ed Bartosh Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

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

filemap: check if dest is written for every block

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

If lenght parameter is provided to sparse_copy call it's mandatory to check if the output file is fully written after reading unmapped block from input file. If it's not done then sparse_copy can write more data than specified length. (From OE-Core rev: 289b1767182982dfb6912e64481150697ba93e4d) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

filemap: change signature of sparse_copy function

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

Renamed parameter offset->skip to match names of dd parameters. Changed affected sparse_copy calls. Added explanation of the parameters to docstring. (From OE-Core rev: 08e2f4e59816c5757686255b267b08cbc46fbd95) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

filemap: add parameter 'length' to sparse_copy

2017-06-14T09:18:28+00:00

Added parameter 'length' to specify amount of data to write into destination file. This is useful when only part of source file should be written into destination file. (From OE-Core rev: cc44e2eb3b5027a3531e6349937a23d73313b3c6) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

filemap: fix skip logic

2017-06-14T09:18:28+00:00

Fixed bug in processing 'skip' parameter: don't read input file if end of bmap block is less than skip Simplified logic of positioning to the start of data inside a partially skipped bmap block.
