2019-10-07Cleanup: Move padd_file function to libtarDavid Oberhollenzer
It's only ever used for padding tarballs. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-27Cleanup: replace fixed with data types with typedefsDavid Oberhollenzer
This is a fully automated search and replace, i.e. I ran this: git grep -l uint8_t | xargs sed -i 's/uint8_t/sqfs_u8/g' git grep -l uint16_t | xargs sed -i 's/uint16_t/sqfs_u16/g' git grep -l uint32_t | xargs sed -i 's/uint32_t/sqfs_u32/g' git grep -l uint64_t | xargs sed -i 's/uint64_t/sqfs_u64/g' git grep -l int8_t | xargs sed -i 's/int8_t/sqfs_s8/g' git grep -l int16_t | xargs sed -i 's/int16_t/sqfs_s16/g' git grep -l int32_t | xargs sed -i 's/int32_t/sqfs_s32/g' git grep -l int64_t | xargs sed -i 's/int64_t/sqfs_s64/g' and than added the appropriate definitions to sqfs/predef.h The whole point being better compatibillity with platforms that may not have an stdint.h with the propper definitions.

2019-08-01Add ability to write_tar_header to embedd extended attributesDavid Oberhollenzer
This commit patches the tar writer to generate a PAX header with SCHILY xattr key/value pairs if requested. The Schily format is used for two reasons: - It is simple - It is apparently more widely supported than the libarchive format Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-07-25Use safer string copy function to fill tar headerDavid Oberhollenzer

2019-07-24Enable largefile supportMatt Turner
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.

2019-07-16cleanup: move error handling into write_retryDavid Oberhollenzer
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 <david.oberhollenzer@sigma-star.at>
2019-07-03Add no-skip option to sqfs2tarDavid Oberhollenzer

2019-07-03tar writer: replace PAX headers with GNU extensionsDavid Oberhollenzer
Some experiments seem to indicate that the various GNU extensions are more widely supported than their POSIX equivalents[1]. Possibly because they are easier to implement and possibly because of the wide spread use of GNU tar. This commit replaces the PAX writer in the write_tar_header implementation with a GNU extension based writer. The writer is also cleaned up by removing all global state. The record counter is moved outside into the tar2sqfs program and passed in as function argument.

2019-07-01cleanup: split tar code up, remove some duplicationsDavid Oberhollenzer
This commit attempts to split some of the monolitic tar parsing code up into multiple functions in seperate files. Also, some code duplication (like reading a record into memory which was implemented twice) is removed. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-01Remove unused variable assignment from tar header writerDavid Oberhollenzer
Mainly to make scan-build happy. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
