Re-structure of Launchpad DNS-STATS Compactor PPAs
by Sara Dickinson March 24, 2026

March 24, 2026

Hi all, As of release 1.2.4 we are re-structuring the Launchpad PPAs for DNS-STATS Compactor. For historic reasons we previously maintained separate PPAs for each Ubuntu release e.g. ppa:dns-stats/compactor-focal ppa:dns-stats/compactor-jammy From 1.2.4 onwards we will be making packages for all Ubuntu releases available in one of two PPAs: ppa:dns-stats/compactor for STABLE production releases ppa:dns-stats/compactor-unstable for UNSTABLE releases (alpha/beta and release candidates) To make this transition we will be performing some housekeeping on the existing PPAs. 1. On the 7th of April the contents of the existing `ppa:dns-stats/compactor` PPA will be deleted (this PPA was previously used for xenial packages). The label will also be updated to be 'DNS-STATS compactor and inspector'. When available, the 1.2.4 stable production releases of DNS-STATS Compactor for focal, jammy and noble will be published here. 2. A new PPA `ppa:dns-stats/compactor-unstable` has been created with the label 'DNS-STATS compactor and inspector (Unstable)' and the 1.2.4~rc1 packages for focal, jammy and noble are available here already. 3. The existing focal and jammy PPAs will be maintained whilst those platforms are supported i.e. the latest packages will still be available from these PPAs too. ppa:dns-stats/compactor-focal ppa:dns-stats/compactor-jammy ppa:dns-stats/compactor-focal-unstable ppa:dns-stats/compactor-jammy-unstable 4. On the 7th of April the following PPAs will be deleted: compactor-0.12 compactor-0.12-bionic compactor-bionic compactor-unstable-bionic Please let us know of any issues or concerns around this process. Sara Dickinson.

Hi all, We are pleased to announce the release of DNS-STATS Compactor version 1.2.2.

DNS-STATS Compactor 1.2.1 release
by Sara Dickinson March 23, 2022

March 23, 2022

Hi all, We are pleased to announce the release of DNS-STATS Compactor version 1.2.1. Full changelog since 1.2.0 ----------------------------------- * Updates: * New `sampling mode` option available when `compactor` is overloaded * Sampling of captured packets can be enabled at a specified rate for a specified time when packet drops exceed a specified threshold (see config options for more details). This option is disabled by default. * The behaviour of the internal sniffer channel is improved when `compactor` is overloaded to provide better reporting and management of dropped/sampled of packets * This fixes a bug where the `Total Packets processed` statistic did not include any packets dropped during overload and so under reported load * Add new statistics to C-DNS: sniffer drops, matcher drops and sampling discards, and 3 libpcap stats. The libpcap stats should not be considered reliable and provided for information only. * Bump the private version because C-DNS schema extended with new statistics. * The behaviour of `compactor` is changed when an interrupt (SIGINT, SIGTERM) is received e.g. when the service is restarted or a user enters ^C. Previously all of the in progress C-DNS compression was aborted and all of the in progress output files (compressed and uncompressed) were removed. Now the `.raw` uncompressed output file is left on disk so it can be manually recovered (i.e. renamed and compressed). Users will now need to choose how to managed these uncompressed files. Behaviour on SIGHUP (re-reading of config file without affecting any in progress compression) is unchanged. * Logging: * New `log-file-handing` option to log low level details of file processing on file rotation and compression. This aids with debugging of file processing problems and measurement of C-DNS file compression times. * New `-D` option (`relaxed-mode`). With this option a warning (not an error) is issued for unrecognized command line and config file options. * Additional default logging is added when file rotation occurs, when compression is aborted, and to report the specific interrupt received by `compactor`. * Improve `log-interval` statistics output and add additional statistics. * Minor updates/bug fixes: * Modify the format output by the debug option `--debug-qr` to be more human readable (`--debug-dns` output is left unchanged). * Fix file durations for files with more than one C-DNS block in them so high traffic rates can be correctly calculated from the statistics. * Constrain size of matcher queue to reduce memory consumption when dropping/sampling. * Fix 2 minor bugs where an incorrect start time could be written to the CDNS file, resulting in a negative file duration. * Fix build issue when using `configure --disable-pseudo-anonymisation`. Thanks Sean Burford for reporting this. * Add example docker image as a submodule in `contrib/dns-stats-docker`. Thanks to Sean Burford for providing this. * Documentation: * Minor documentation update to address https://github.com/dns-stats/compactor/issues/80 * Text added in the documentation to clarify time patterns are needed in file output patterns for filename based file rotation to occur (based on the `rotation-period` option). * Correct the dependency list.
