core.flist #

fn merge(source string, destination string) !

merge merges two flists together.

• copies all routes
• copies all inodes with the following restrictions:
• no two entries can have the same inode number. this can happen by shifting an flist's inode numbers to start after the last inode number of the other flist.
• the changed flist should reflect the inode changes on all affected tables (extra and block).
• no two files that exist in the same dir can have the same name.
• if two files have the same name and have the same blocks, they are identical and won't be copied, otherwise, the incoming entry is renamed.

fn new(args FlistGetArgs) !Flist

struct Block {
pub mut:
	ino u64
	id  string
	key string
}

struct Extra {
pub mut:
	ino  u64
	data string
}

struct Flist {
	path string
	con  sqlite.DB
}

fn (mut f Flist) add_routes(new_routes []Route) !

add_routes adds routes to the route table of the flist

fn (mut f Flist) copy(source string, destination string) !

copy copies an flist entry from source path to destination path.

fn (mut f Flist) delete_match(pattern string) !

delete_match deletes any entry that matches pattern. it simply calls find() and deletes matching inodes.

fn (mut f Flist) delete_path(path_ string) !

delete file or directory from flist. path is relative to flist root directory. empty path will delete all flist entries. (actual data is not deleted, only flist information)

fn (mut f Flist) find(pattern string) ![]Inode

find entries that match pattern, it uses the LIKE operator; The percent sign (%) matches zero or more characters and the underscore (_) matches exactly one.

fn (mut f Flist) get_routes() ![]Route

get_routes returns all flist routes

fn (mut f Flist) list(recursive bool) ![]Inode

list directories and files in root directory. if recursive is allowed directories are explored.

fn (mut f Flist) update_routes(new_routes []Route) !

update_routes will overwrite the current routes with the new routes
