23 * Abstract base class for the database used by PhpWiki.
25 * A <tt>WikiDB</tt> is a container for <tt>WikiDB_Page</tt>s which in
26 * turn contain <tt>WikiDB_PageRevision</tt>s.
28 * Conceptually a <tt>WikiDB</tt> contains all possible
29 * <tt>WikiDB_Page</tt>s, whether they have been initialized or not.
30 * Since all possible pages are already contained in a WikiDB, a call
31 * to WikiDB::getPage() will never fail (barring bugs and
32 * e.g. filesystem or SQL database problems.)
34 * Also each <tt>WikiDB_Page</tt> always contains at least one
35 * <tt>WikiDB_PageRevision</tt>: the default content (e.g. "Describe
36 * [PageName] here."). This default content has a version number of
39 * <tt>WikiDB_PageRevision</tt>s have read-only semantics. One can
40 * only create new revisions or delete old ones --- one can not modify
41 * an existing revision.
45 * Open a WikiDB database.
47 * This is a static member function. This function inspects its
48 * arguments to determine the proper subclass of WikiDB to
49 * instantiate, and then it instantiates it.
53 * @param hash $dbparams Database configuration parameters.
54 * Some pertinent paramters are:
57 * <dd> The back-end type. Current supported types are:
60 * <dd> Generic SQL backend based on the PEAR/DB database abstraction
61 * library. (More stable and conservative)
63 * <dd> Another generic SQL backend. (More current features are tested here. Much faster)
65 * <dd> Dba based backend. The default and by far the fastest.
73 * <dd> (Used by the SQL and ADODB backends.)
74 * The DSN specifying which database to connect to.
77 * <dd> Prefix to be prepended to database tables (and file names).
80 * <dd> (Used by the dba backend.)
81 * Which directory db files reside in.
84 * <dd> Used only by the dba backend so far.
85 * And: When optimizing mysql it closes timed out mysql processes.
86 * otherwise only used for dba: Timeout in seconds for opening (and
87 * obtaining lock) on the dbm file.
90 * <dd> (Used by the dba backend.)
92 * Which dba handler to use. Good choices are probably either
96 * @return WikiDB A WikiDB object.
