Replace update_crc32 helper function with crc32 from zlib

2019-08-18T20:53:32+00:00

It is optimized to the maximum and if we already use zlib anyway, why not use zlib crc32? This also makes zlib a hard dependency which also means the whole "do we have a compressor" sanity check in the build system can be removed. Signed-off-by: David Oberhollenzer

Implement support for SOURCE_DATE_EPOCH environment variable

2019-08-02T09:41:36+00:00

reproducible-builds.org suggests the use of an environment variable as a source for time stamps: https://reproducible-builds.org/specs/source-date-epoch/ This commit adds support for setting the default mtime from the variable, if it is set and only defaulting to 0 if not. The timestamp given by the command line switch takes precedence. Signed-off-by: David Oberhollenzer

Update print_version text

2019-07-30T05:20:36+00:00

This commit updates the text issued by print_version() to reflect in some way that the software contains contributions from co-authors. The original text was based on the sterotypical --version output of GNU coreutils programs. It may have to be rewritten eventually. Signed-off-by: David Oberhollenzer

Enable largefile support

2019-07-24T07:16:16+00:00

Requires that config.h be included before other headers, since the macro _FILE_OFFSET_BITS changes the definitions of things like 'struct stat'. I chose to simply include it at the top of every C file and at immediately after the double-inclusion guards of every header. Signed-off-by: Matt Turner Signed-off-by: David Oberhollenzer

Keep track of xattr key & value references AFTER deduplication

2019-07-21T11:30:34+00:00

This commit adds a reference count functionality to the string table implementation and uses this functionality in the fstree code to count how often each key and value is referenced by the deduplicated Xattr blocks. This is needed to support deduplication through out-of-band storage of xattrs. 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
