Macro Definition Documentation
◆ GLASS_BTREE_CURSOR_LEVELS
| #define GLASS_BTREE_CURSOR_LEVELS 10 |
Allow for this many levels in the B-tree.
With 10, overflow is practically impossible. FIXME: but we want it to be completely impossible...

◆ GLASS_DEFAULT_BLOCKSIZE
| #define GLASS_DEFAULT_BLOCKSIZE 8192 |
Default B-tree block size.
Definition at line 30 of file glass_defs.h.
Referenced by GlassDatabase::compact(), and GlassDatabase::GlassDatabase().
◆ GLASS_MAX_BLOCKSIZE
| #define GLASS_MAX_BLOCKSIZE 65536 |
Maximum B-tree block size.
Definition at line 36 of file glass_defs.h.
Referenced by Glass::RootInfo::unserialise().
◆ GLASS_MAX_DOCID
| #define GLASS_MAX_DOCID Xapian::docid(0xffffffffffffffff) |
The largest docid value supported by glass.
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.
