[odb-announcements] ODB 1.2.0 released

[Boris Kolpackov]

Hi,

We have released ODB 1.2.0. The NEWS file entries for this release are
as follows:

  * New profile, boost, provides persistence support for the Boost libraries.
    This version covers the most commonly used types from the smart_ptr,
    unordered, and date_time libraries. For example, now you can write:

    #pragma db object
    class employee
    {
      ...

      boost::gregorian::date born_;
      boost::unordered_set<std::string> emails_;
      boost::shared_ptr<employer> employer_;
    };

    The boost profile implementation is provided by the libodb-boost library.
    For more information refer to Chapter 11, "Profiles Introduction" and
    Chapter 12, "Boost Profile" in the ODB manual as well as the 'boost'
    example in the odb-examples package.

  * Support for embedded database schemas. The new option, --schema-format,
    allows the selection of the schema format. The valid values for this
    option are 'sql' for a standalone SQL file and 'embedded' for a schema
    embedded into the generated C++ code. The new odb::schema_catalog class
    provides support for accessing embedded schemas from within the
    application. For details refer to Section 3.3, "Database" in the ODB
    manual as well as the 'schema/embedded' example in the odb-examples
    package.

  * New exceptions: odb::recoverable, odb::connection_lost, and odb::timeout.
    The odb::recoverable exception is a common base class for all recoverable
    ODB exceptions. The other two exceptions plus odb::deadlock now inherit
    from this base. Refer to Section 3.5, "Error Handling and Recovery" for
    details.

  * Support for connection validation (ping) in MySQL connection_pool_factory.
    This transparently deals with the MySQL server closing connections after
    a certain period of inactivity.

  * New namespace, odb::core, contains using-declarations for the core ODB
    constructs, such as the database, transaction, etc. The primary use of
    this namespace is in the using-directives:

    using namespace odb::core;

    The above form should be preferred over the old variant:

    using namespace odb;

    The new approach brings all the essential ODB names into the current
    namespace without any of the auxiliary objects such as traits, etc., which
    minimizes the likelihood of conflicts with other libraries.  Note that you
    should still use the odb namespace when qualifying individual names, for
    example, odb::database.

  * New option aliases: -q for --generate-query and -s for --generate-schema.

  * Support for the default options file. Now, if configured, the ODB compiler
    loads the default options file (by default ../etc/odb/default.options,
    relative to the ODB compiler binary). This file can be used for
    installation-wide customization, such as adding extra include search
    paths.

Source code and pre-compiled binary packages for this release are available
