Move data writer ostream into libsquashfs

2023-06-17T13:27:19+00:00

It is mainly a very thin wrapper on top of the block processor so far. Signed-off-by: David Oberhollenzer

libio: remove ostream_append_sparse and fallback implementation

2023-06-15T11:38:25+00:00

Instead of a separate append-sparse function, simply accept NULL as an input for append. For both Unix and Win32, a fallback needs to be implemented. For XFRM, we can just memset the input buffer to zero, same for the libsquashfs data writer. Signed-off-by: David Oberhollenzer

libsquashfs: remove the default block writer alignment feature

2023-04-01T10:25:02+00:00

The idea of the block align feature was to allow micro-managing that some files are forcefully aligned to 1k/4k ("device block") boundaries, hoping to improve access time at the cost of data density. The feature was not exposed in the tools for a long time and eventuall added to the sort file. Measurement and experimentation showed, that it in fact worsened the read performance on a test system with an old micro SD card as the bottle neck. The feature is removed, and if needed, can be brought back simply by wrapping/sub-classing the default block writer, if need be.. Signed-off-by: David Oberhollenzer
