fstree: add support for spaces in filenames

2019-07-17T09:05:42+00:00

This commit adds a mechanism to fstree_from_file to support filenames with spaces in them by quoting the entire string. Quote marks can still be used inside file names by escaping them with a backslash. Back slashes (if that is your thing) can also be escaped. Signed-off-by: David Oberhollenzer

cleanup: move error handling into read_retry

2019-07-16T20:48:00+00:00

If read_retry fails to read the expected amount of data (EOF or otherwise), it is almost always an error. This commit renames read_retry to read_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer

cleanup: move error handling into write_retry

2019-07-16T20:47:59+00:00

If write_retry fails to write everything, it is *always* an error. This commit renames write_retry to write_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer

Fix directory index creation

2019-07-16T20:47:59+00:00

Digging around in kernel internals and mksquashfs reveals that it is actually a buffer offset into the raw directory buffer. The error hasn't been noted until now because of the bug fixed by a5428e0. Signed-off-by: David Oberhollenzer

Add flags to data writer to micro manage behaviour

2019-07-15T12:47:03+00:00

The added flags allow controlling the following on a per file level: - forcing a file to be written uncompressed - forcing a file to not have a fragment, i.e. the last truncated block actually being written as a block - padding a file to be alligned to device block size The flags are not yet exposed to anything user controllable (such as command line flags).

Add generic support for reading files without fragments

2019-07-12T13:45:00+00:00

This commit extends the special case handling for sparse files to generically support reading files that don't have a fragment but instead have a trunkated final block. Signed-off-by: David Oberhollenzer

Simplify writer code for files without a fragment

2019-07-12T13:45:00+00:00

The data writer sparse block code can take advantage that it can add a block size instead of a fragment and doesn't have to initialize the framgent location. In return, the tree node to inode serialization code doesn't need a special case for sparse file anymore and can now also handle files that are forced to not have a fragment.

fstree: mknode: initialize fragment data, add extra blocksize slot

2019-07-12T13:44:14+00:00

This commit makes sure that regular file tree nodes have one more slot than necessary to support files that don't have fragments. Also, it initializes the fragment data, which should help to deduplicate some code ahead. Signed-off-by: David Oberhollenzer

Fix dirindex writing for ext dir inode

2019-07-10T10:31:45+00:00

This commit makes sure we write the index count to the inode before writing out the inode itself. Signed-off-by: David Oberhollenzer

libsqfs: eleminate use of temporary file

2019-07-10T09:26:22+00:00

Tell the directory writer to keep the directory blocks in memory, then write them out once everything is done and the inodes are all written out. Signed-off-by: David Oberhollenzer
