The Perl Toolchain Summit needs more sponsors. If your company depends on Perl, please support this very important event.

Changes for version 0.36 - 2005-02-07

  • BufCa/bce: set fileread flag in buffercache element when reading blocks in to counteract the spurious dirtyflag setting when the bigbuf gets updated. Set filenum/blocknum *before* the fileread so GetInfo is up-to-date.

Modules

Row Directory Block Array interface
Row Directory Block Adjunct tied hash class. This class adds array-like splice capabilities to Genezzo::Block::RDBlock. Genezzo::Block::RDBArray uses this class as the basis of a tied array.
Row Directory Block Not Null (array) tied hash class.
Row Directory Block tied hash class. A class that lets you treat the contents of a block (byte buffer) as a hash.
row directory
Standard Block
A simple in-memory buffer cache for multiple files for a single process, without locking.
A simple in-memory buffer cache for a single process, without locking.
Buffer Cache Element
Detect modifications to scalar
detect destruction of scalar
The Genezzo data dictionary
a feeble parser
an extensible database with SQL and DBI
Cry Havok! And Let Slip the Dogs of War!
some example havok functions
load the SysHook table
load the UserExtend table
basic btree
persistent btree
btree Hash tied hash class. Makes a persistent btree based upon Genezzo::Block::RDBlock look like a conventional hash.
a 90% pure virtual class module that extends hierarchical "push hash" Genezzo::PushHash::hph with Row/Block methods. These methods facilitate the construction of classes that manipulate data blocks directly, such as index access methods and functions that split rows over multiple blocks..
Push Hash Array implementation
fixed-size push hash
Push Hash that only supports delete and insert
an impure virtual class module that defines a "push hash", a hash that generates its own unique key for each value. Values are "pushed" into the hash, similar to pushing into an array.
an impure virtual class module that defines a *hierarchical* "push hash", a hash that generates its own unique key for each value. Values are "pushed" into the hash, similar to pushing into an array. Hierarchical pushhashes must be supplied with a factory method which manufactures additional pushhashes as necessary.
Row Source Block
Row Source File tied hash class.
Row Source InDeX tied hash class. A hierarchical pushhash (see Genezzo::PushHash::hph) class that stores a pushhash as a btree via Genezzo::Row::RSTable.
Row Source TABle tied hash class.
File Space Management
Table Space Hash
a class that defines a tablespace, the relationship between a collection of files on disk and a set of tables in the dictionary.
