Version 2.1.90 (git)

* Modules are loaded using plain dlopen/dlsym

* New dispatch condition: in

The condition "ARG in NAME", where ARG is "key" or "map" and NAME is a
database name evaluates to true if the lookup of ARG in the database
NAME gives positive result, i.e. a response beginning with the word "OK".

* New module: getent

* New module: lua

* Modules can indicate per-database capabilities

The smap_module structure has a new member, smap_dbcap, which
can be called in order to determine capabilities provided by a
particular database:

   int (*smap_dbcap)(smap_database_t dbp)

This function is used when the smap_capabilities value has the
SMAP_CAPA_DBCAP flag set.  The function returns actual database
capabilities as a bitmask.  Notice, that smap_dbcap is called
and the returned value consulted only if the module reports a
particular capability.  I.e. in the presence of SMAP_CAPA_DBCAP,
the SMAP_CAPA_QUERY and SMAP_CAPA_XFORM capability mean that
a module can provide a particular capability, but the actual
database is not required to do so.

* New configuration statements

- prepend-load-path

Adds specified path at the beginning of the current load path

- append-load-path

Sinonym to `load-path'

* `Key' condition

New dispatch condition `key' compares key with the given pattern.  As
with `map' three kinds of comparison are supported: literal, globbing
pattern and regular expression.

* Transform capability

Transform capability is an optional feature provided by some
databases.  It allows for transforming requests following certain
rules.

Transforms are requested in dispatch rules, e.g.:

   dispatch key like <*>   transform key dequote

This rule applies to any request which has its key enclosed in
angle brackets.  It applies the transformation method `dequote'
(which should be defined prior to this statement) to the
key.  After the method returns, scanning dispatch rules is
resumed with the modified key value.

* New module `sed'

This module allows to modify queries using sed-like expressions.
For example, the declaration of the `dequote' database, used in
the example above, could be:

# Load the sed module
module sed sed
# Dequote database: removes angle brackets surrounding the argument
database dequote sed 's/<(.*)>/\1/'

* New module `mysql'

Provides an interface to MySQL DBMS.

* New module `postgres'

Provides an interface to PostgreSQL DBMS.
