Detailed Description
Definitions, types, etc for use inside honey.
Definition in file honey_defs.h.
Macro Definition Documentation
◆ HONEY_DOCLEN_CHUNK_MAX
| #define HONEY_DOCLEN_CHUNK_MAX 2017 |
Definition at line 50 of file honey_defs.h.
◆ HONEY_MAX_DOCID
| #define HONEY_MAX_DOCID Xapian::docid(0xffffffffffffffff) |
The largest docid value supported by honey.
The disk format supports 64-bit docids, but if Xapian::docid is narrower then it's the largest value supported by the type that matters here.
Definition at line 64 of file honey_defs.h.
◆ HONEY_MAX_KEY_LENGTH
| #define HONEY_MAX_KEY_LENGTH 255 |
Maximum key length.
Definition at line 39 of file honey_defs.h.
◆ HONEY_MIN_DB_SIZE
| #define HONEY_MIN_DB_SIZE 2048 |
Minimum size to pad a honey table to.
Having this minimum size means we can usually know from the size that a stub database file isn't a single file database.
Definition at line 36 of file honey_defs.h.
◆ HONEY_POSTLIST_CHUNK_MAX
| #define HONEY_POSTLIST_CHUNK_MAX 2000 |
Maximum size of a postlist chunk in bytes.
This isn't a hard maximum, but we won't exceed it by much.
FIXME: 2000 is what glass uses, but we should probably tune this.
Definition at line 47 of file honey_defs.h.
◆ HONEY_TABLE_EXTENSION
| #define HONEY_TABLE_EXTENSION "honey" |
Honey table extension.
Definition at line 29 of file honey_defs.h.
◆ KEY_DOCLEN_PREFIX
| #define KEY_DOCLEN_PREFIX "\0\xf7" |
Definition at line 93 of file honey_defs.h.
◆ SST_SEARCH
| #define SST_SEARCH |
Definition at line 26 of file honey_defs.h.
Typedef Documentation
◆ honey_block_t
| typedef uint4 honey_block_t |
A block number in a honey Btree file.
Definition at line 101 of file honey_defs.h.
◆ honey_revision_number_t
| typedef uint4 honey_revision_number_t |
The revision number of a honey database.

◆ honey_tablesize_t
| typedef unsigned long long honey_tablesize_t |
How many entries there are in a table.
Definition at line 107 of file honey_defs.h.
