Upgrade

This document contains the upgrade information between the major versions of DSC for the eventual breaking changes, please read CHANGES for the new features added.

From dsc-201502251630 to v2.0.0

The dsc-201502251630 was the last version release before the use of version numbering.

Install Paths

Since the conform to FHS 3.0 paths have been changed but will only affect new installations where configure is not touched.

In previous version INSTALLDIR was set to /usr/local/dsc, this is now controlled by Automake and configure using --prefix=DIR or individual path options as below. See configure --help for information about default paths and how to control each of them.

  • upload-* scripts was previously installed in $INSTALLDIR/libexec, is now installed in $libexecdir/dsc.
  • dsc.conf.sample was previously installed in $INSTALLDIR/etc, is now installed in $sysconfdir/dsc.
  • dsc was previously installed in $INSTALLDIR/bin, is not installed in $bindir.

Data Files Path

The path to dsc data files that it output has been changed to $localstatedir/lib/dsc but only affects the path in dsc.conf.sample during installation. If you use an old configuration then dsc will store the data files in the same path as before. This can be controlled by configure --with-data-dir=DIR.

Configuration

Dataset names have been made unique so dsc will not start if there are duplicates, you need to change the configuration so that all datasets are unique.

The following indexers have been removed since they are only aliases:

  • cip4_addr, use client instead.
  • cip4_net, use client_subnet instead.
  • d0_bit, use do_bit instead.

Upload Scripts Deprecated

Altho the upload scripts are still installed they are now considered deprecated and will be removed in future versions.

The uploads scripts where constructed for the purpose of uploading dsc data to DNS-OARC and that is a very specific purpose that does not belong in a software repository. It can be replaced by instructions specific for each organization that needs to do it.

PID File

The PID file is now locked and dsc will not start if another process has it locked.
