3139 | * functions (list_plain_entries (twice), list_instance_entries, | |
3140 | * list_olh_entries) that each list segments of the index space rather | |
3141 | * than just move a marker through the space from start to end. The | |
3142 | * reason is that a name filter may be provided in the op, and in that | |
3143 | * case most entries will be skipped over, and small segments within | |
3144 | * each larger segment will be listed. | |
3145 | * | |
3146 | * Ideally, each of the three segment functions should be able to | |
3147 | * handle a marker and filter, if either/both is provided, | |
3148 | * efficiently. So, for example, if the marker is after the segment, | |
3149 | * ideally return quickly rather than iterating through entries in the | |
3150 | * segment. | |
3151 | * | |
3152 | * Additionally, each of the three segment functions, if successful, | |
3153 | * is expected to return the number of entries added to the output | |
3154 | * list as a non-negative value. As per usual, negative return values | |
3155 | * indicate error condtions. | |

3810 | * We hold the garbage collection chain data under two different |
3811 | * indexes: the first 'name' index keeps them under a unique tag that | |
3812 | * represents the chains, and a second 'time' index keeps them by | |
3813 | * their expiration timestamp. Each is prefixed differently (see | |
3814 | * gc_index_prefixes below). | |
3815 | * | |
3816 | * Since key-value data is listed in lexical order by keys, generally | |
3817 | * the name entries are retrieved first and then the time entries. | |
3818 | * When listing the entries via `gc_iterate_entries` one parameter is | |
3819 | * a marker, and if we were to pass "1_" (i.e., | |
3820 | * gc_index_prefixes[GC_OBJ_TIME_INDEX]), the listing would skip over | |
3821 | * the 'name' entries and begin with the 'time' entries. | |
3822 | * | |
3823 | * Furthermore, the times are converted to strings such that lexical | |
3824 | * order correlates with chronological order, so the entries are | |
3825 | * returned chronologically from the earliest expiring to the latest | |
3826 | * expiring. This allows for starting at "1_" and to keep retrieving | |
3827 | * chunks of entries, and as long as they are prior to the current | |
3828 | * time, they're expired and processing can continue. | |
