| 106 | * Because on large systems, many files can be exec'ed, |
| 107 | * a static table size may grow to be too large. |
| 108 | * |
| 109 | * Table elements are allocated in chunks dynamically, linked |
| 110 | * together so that they may be retrieved sequentially. |
| 111 | * |
| 112 | * An index into the table structure is provided by hashing through |
| 113 | * a seperate hash table. |
| 114 | * The hash table is segmented, and dynamically extendable. |
| 115 | * Realize that the hash table and accounting information is kept |
| 116 | * in different segments! |
| 117 | * |
| 118 | * We have a linked list of hash table segments; within each |
| 119 | * segment we use a quadratic rehash that touches no more than 1/2 |
| 120 | * of the buckets in the hash table when probing. |
| 121 | * If the probe does not find the desired symbol, it moves to the |
| 122 | * next segment, or allocates a new segment. |
| 123 | * |
| 124 | * Hash table segments are kept on the linked list with the first |
| 125 | * segment always first (that will probably contain the |
| 126 | * most frequently executed commands) and |
| 127 | * the last added segment immediately after the first segment, |
| 128 | * to hopefully gain something by locality of reference. |
| 129 | * |
| 130 | * We store the per user information in the same structure as |
| 131 | * the per exec'ed file information. This allows us to use the |
| 132 | * same managers for both, as the number of user id's may be very |
| 133 | * large. |
| 134 | * User information is keyed by the first character in the name |
| 135 | * being a '\001', followed by four bytes of (long extended) |
| 136 | * user id number, followed by a null byte. |
| 137 | * The actual user names are kept in a seperate field of the |
| 138 | * user structure, and is filled in upon demand later. |
| 139 | * Iteration through all users by low user id to high user id |
| 140 | * is done by just probing the table, which is gross. |
