Things to be done

• Test and fix library, so that it will also compile under linux
• Provide necessary fallback stuff, so that library can also be used without c library
• Finish FAT library read support
  • Finish implementation of fat_file_read
• Add FAT library write support
  • Add test where cluster chain needs to be extended <= Within truncate tests
  • Extend test creating a folder to fail on second try
  • Add test creating a directory with long name
  • Add file write support
  • Add tests for file truncate
  • Add logic to support O_TRUNC on open
  • Add test for creating a plain file with O_CREAT
  • Add test for file truncation on open with O_TRUNC
  • Add test to ensure that read only is working correctly
  • Add test to read a write only opened file
  • Add test for write append with O_APPEND
  • Add test for writing a file
  • Add test creating a file with short name
  • Add test creating a file with long name
  • Add test creating a file with short name but long extension, e.g. foo.jpeg
• Fix read out of directory via fat directory next when switching to new cluster
• Implement fat_file_move
• Implement fat_file_remove
• Implement fat_directory_remove
• Implement fat_directory_move
• Check and add proper handling for empty files, which means start cluster is 0
  • Truncate with size 0 should free cluster chain
  • Write needs to be adjusted so that it requests a cluster on demand
• Fix directory deletion to set deletion value instead of 0 overwrite
• Copy file entry information on move like creation date
• Adjust cluster of directory entry .. on folder move
• Add test to ensure .. is changed correctly
• Something in the implementation destroys the fat image
• Add write transaction instead of direct writing with some sort of cache accessed
• Add proper locking to library functions
• Optimizations
  • Introduce some sort of read/write cache instead of transactions caching blocks until drain / flush
• Cleanup
  • Check written code and simplify it once everything works
  • Check code and deduplicate similar code like file move or folder move
  • Extend functions by transactions where it might be necessary
• Split up tests in single files
• Create unit tests
  • Prepare unit testing with cmake and ctest
  • Prepare a test blockdev driver for unit testing
  • Add unit tests for specific functions
• Add support for ext2
• Fix and complete documentation
• Add custom commands to test folder to create necessary images for tests
• Check usages of block size and evaluate whether automatical adjustment is meaningful for fat
• Add code coverage collection
  • Get ctest coverage command to run
  • Get html coverage output
