2019-12-23Bring back the flat list of inodes in libfstreeDavid Oberhollenzer
It makes further processing simpler and doesn't leak the abstraction into upper layers. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-12-18Cleanup: internalize some fstree functionsDavid Oberhollenzer

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.

2019-09-27Cleanup: remove most of the payload pointer magic from libfstreeDavid Oberhollenzer
Now that dir_info_t and file_info_t have reasonably small, use them in tree_node_t directly instead of doing pointer arithmetic magic on the payload area. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-08-02Implement support for SOURCE_DATE_EPOCH environment variableDavid Oberhollenzer
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 <david.oberhollenzer@sigma-star.at>

2019-07-24cleanup: remove atime/ctime processing codeDavid Oberhollenzer
This commit removes all the code for parsing and processing atime/ctime and values and related test code. Caring about those is kind of pointless because squashfs can only store mtime in inodes. The only relevant place is when generating a struct stat from a squashfs inode or an fstree node. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
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.

2019-06-23Move fstree default option processing to fstree codeDavid Oberhollenzer
Instead of decomposing a default string in gensquashfs option processing, move that to fstree_init instead and pass the option string directly to fstree_init. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-06-19Cleanup fstree codeDavid Oberhollenzer
Replace default_$FIELD with a struct stat. Merge the rest of add_node/add_file into mknode and add by path+stat. Expose the mknode function and replace all the duplicated node pointer arithmetic magic with a call to mknode. Plus a generic cleanup by utlizing new util functions.

2019-06-10Generate a flat inode table from the fstree ahead of timeDavid Oberhollenzer
Instead of allocating inode numbers as we go, generate and populat an inode table from the fstree ahead of time. This makes processing nodes a little bit simpler and we will need that table anyway for NFS export support later on. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-19Add extended attributes to fstreeDavid Oberhollenzer
We use a str_table_t to generate unique IDs for all unique keys and all unique values and then use a post processing step to deduplicate xattr listings. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
