This pull request adds full support for symbolic links (symlinks) to the container format and CLI tools. The changes include the ability to add, list, extract, and display information about symlinks, as well as improvements to the test suite to verify symlink handling. The implementation ensures correct preservation of symlink targets, metadata, and compatibility with compression and encryption.
Symlink Support:
bfc_add_symlinkand its implementation to allow adding symlinks to containers, storing their target and metadata (include/bfc.h,src/lib/bfc_writer.c). [1] [2]cmd_createcommand to detect symlinks during both directory and file processing, and to add them using the new API (src/cli/cmd_create.c). [1] [2] [3] [4]Symlink Extraction:
src/cli/cmd_extract.c). [1] [2]lutimesusage to set symlink timestamps and improved error handling for existing files during extraction (src/cli/cmd_extract.c). [1] [2]Symlink Information and Listing:
cmd_infoandcmd_listcommands to recognize and display symlinks, including type, count, and mode in summary and detailed outputs (src/cli/cmd_info.c,src/cli/cmd_list.c). [1] [2] [3] [4] [5] [6]Testing and Build System:
