TODO

• we need locking and retires to handle multiple writes to the same directory and file
• EFAULT->EIO
• do we need to check permissions against user uid/gid and print EACCES ?
• MRT blocked->EBUSY
• EEXIST,ENOTDIR,EISDIR,EFBIG,ENOSPC,ETIMEDOUT,ENOTEMPTY
• Add a github workflow to make linux releases

Wishlist

• multi-asd-record file storage - to allow for files larger than 8MiB
  • PK=(string)=inode_blockNo
  • will affect truncate
  • will affecrt truncate(stat)
  • will affect file read
  • will affect file write
  • will affect remove
  • store no more than 7MiB per block, leaving 1MiB for other bins, metadata, overheads, expansion, etc
  • implement menthods for partial reads (offset reads)
