Dear all,

A new stable release of Gfarm 1.3.1 is now available for download.

The version 1.3.1 is improved in stability and usability since the
version 1.3 released this June.  In particular, the version 1.3.1
contains several critical bug fixes for the new features added in
the version 1.3.  We recommend you to update your Gfarm
environment.

Release note for Gfarm 1.3.1
============================

[2006.8.4]

New Features

  * gfchmod(1) - chmod command for Gfarm.

  * gfusage(1) - display total disk space usage of each user.

  * Documentation

  - KNOWN_PROBLEMS - describe known problems of Gfarm 1.3.1.

Update Features

  * libgfarm

  - improve the functionality of connection cache for gfsd to tolerate
    restart of gfsd, and not to exhaust the file descriptors.  Now,
    the number of cached connections is managed by the
    'gfsd_connection_cache' directive in gfarm.conf (default is 16).

  - add definition of gfarm_error_t and GFARM_ERR_NO_ERROR, and
    gfarm_error_string(3) function.

  - report an error in closing a connection.

  - devise a countermeasure against integer overflow attack by using
    malloc() and realloc() in a safe way.

  * gfarm_agent(1)

  - add "-m" option for master mode in case that there is a single
    gfarm_agent metadata cache server running.  This improves metadata
    access performance by caching path information also.

  * config-gfarm(1)

  - add "-a <auth_type>" option for specifying an authentication type.

  - support the PostgreSQL 7.4 as a metadata server.

  - show usage with "--help" option.

  - set keepalive option by default to cope with poor networking
    environment.

  * config-gfsd(1)

  - change spool-directory argument to be optional.

  - add "-l" option which specifies a listen address.

  - show usage with "--help" option.

  * config-agent(1)

  - show usage with "--help" option.

  * gfsd(8)

  - add "-l" option which specifies a listen address,

  - support read-only mode experimentally, which is enabled by
    creating ".readonly" file in the top spool directory by
    administrators.

  * Documentation

  - describe about a file/directory owner problem in README.hook.

  * Bug fix

  - fix a big scheduling bug such that local disk does not have
    priority to be scheduled, introduced by the Gfarm version 1.3.

  - fix a portability problem to x86_64.

  - fix a bug regarding reconnection to gfarm_agent.

  - gfsd(8) - fix disk space calculation on FFS on *BSDs.

  - fix a bug of mkdir(1) via system call hooks on Solaris 9.

Unsupported Features

 * NetBSD 1.6.2 is not supported anymore.
