Feature Summary

The 1.10.0 release of LDAS was tagged in CVS on July 19, 2007. This release focused on a rewrite of frameCPP to unify implementation of all versions of the frame specification and some improvements to the diskcacheAPI to enhance its tolerence of system related issues.

The use of TCL's exec function to spawn a process and obtain its output has been greatly reduced. This enhances the performance for APIs that use threads.

Most of the system tests are now controlled by a single automated script and the support files for the tests are now distributed with the release of the software.

Support for CentOS 5.2 has superceeded support for Fedora Core 4.

Summary by API

Disk Cache API

Detection of modified mount points has been enhanced with the introduction of using statvfs to detect if any changes on a file system have occurred.

The staging of SAM-QFS files have been moded the the frameAPI.

Frame API

Several calls have been threaded resulting in the frameAPI being more responsive.

Staging of data now happens in the frameAPI where it can detect the file system type and use the SAM-QFS API. This eliminates the spawning of a process and only makes staging request for file systems that support it.

frameCPP

The core of the library was rewritten to enhance code reusability in preperation for supporting the version eight frame specification. Support for version five frames has been dropped.
