4 This is the format for a file-based stack which works as any other Stackable
9 Purpose: | "magic" | separator | count | separator | position | separator |
10 ---------+-----------+-----------+----------+-----------+------0---+-----------+
11 Bytes: | 9 | 1 | 20 (hex) | 1 | 20 (hex) | 1 |
12 ---------+-----------+-----------+----------+-----------+----------+-----------+
13 Example: | STACKv1.0 | 01 | 00...ff | 01 | 00...ff | 02 |
17 Purpose: | hash 0 | separator | name 0 | entry 0 | hash n | separator | name n | entry n | EOF |
18 ---------+--------+-----------+--------+------------+--------+-----------+--------+------------+-----+
19 Bytes: | 64 | 1 | 10 | 1-n (pack) | 64 | 1 | 10 | 1-n (pack) | 1 |
20 ---------+--------+-----------+--------+------------+--------+-----------+--------+------------+-----+
21 Example: | abc | 03 | foo | ... | abc | 03 | bar | ... | EOF |
25 magic - Identifies the file and version of format
26 separator - Serves to detect end of strings with unknown/flexible length
27 count - Total amount of entries (not deleted) encoded in hexa-decimal
28 position - Seek position of current entry (which current() will give)
29 hash X - Hash sum of entry X (SHA 256)
30 name X - Name of stack the entries belongs in
31 entry X - The actual data, compressed with pack()
32 EOF - End-of-file character
34 ??? - Must be still found out which character/hashing algorthym fits best
