2919 | * functions (list_plain_entries (twice), list_instance_entries, | |
2920 | * list_olh_entries) that each list segments of the index space rather | |
2921 | * than just move a marker through the space from start to end. The | |
2922 | * reason is that a name filter may be provided in the op, and in that | |
2923 | * case most entries will be skipped over, and small segments within | |
2924 | * each larger segment will be listed. | |
2925 | * | |
2926 | * Ideally, each of the three segment functions should be able to | |
2927 | * handle a marker and filter, if either/both is provided, | |
2928 | * efficiently. So, for example, if the marker is after the segment, | |
2929 | * ideally return quickly rather than iterating through entries in the | |
2930 | * segment. | |
2931 | * | |
2932 | * Additionally, each of the three segment functions, if successful, | |
2933 | * is expected to return the number of entries added to the output | |
2934 | * list as a non-negative value. As per usual, negative return values | |

3593 | * their expiration timestamp. Each is prefixed differently (see | |
3594 | * gc_index_prefixes below). | |
3595 | * | |
3596 | * Since key-value data is listed in lexical order by keys, generally | |
3597 | * the name entries are retrieved first and then the time entries. | |
3598 | * When listing the entries via `gc_iterate_entries` one parameter is | |
3599 | * a marker, and if we were to pass "1_" (i.e., | |
3600 | * gc_index_prefixes[GC_OBJ_TIME_INDEX]), the listing would skip over | |
3601 | * the 'name' entries and begin with the 'time' entries. | |
3602 | * | |
3603 | * Furthermore, the times are converted to strings such that lexical | |
3604 | * order correlates with chronological order, so the entries are | |
3605 | * returned chronologically from the earliest expiring to the latest | |
3606 | * expiring. This allows for starting at "1_" and to keep retrieving | |
