collector/CHANGELOG.md
Karsten Loesing 5a0e6be21c Remove dependency on metrics-lib's internal package. 
The only functionality contained in metrics-lib's internal package is
file (de-)compression, which in turn uses a third-party library that
we're using anyway. This is a weak reason for depending on our own
library for this functionality. Removing this dependency will make it
easier to make changes to our library in the future.

The new FileType class is based on a copy of the same enum type in
metrics-lib without @since tags and without methods that we don't use.

Raw Blame History

Changes in version 1.1?.? - 2019-1?-??

  • Medium changes

    • Give up on periodically checking the configuration file for updates and reloading it in case of changes.

  • Minor changes

    • Remove dependency on metrics-lib's internal package.

Changes in version 1.13.1 - 2019-11-11

  • Minor changes
    • Update to metrics-lib 2.9.1.

Changes in version 1.13.0 - 2019-11-09

  • Medium changes
    • Extend index.json by including descriptor types, first and last publication timestamp, and SHA-256 file digest. Requires making configuration changes in collector.properties:
      1. IndexedPath is a new directory with subdirectories for archived and recent descriptors,
      2. ArchivePath and IndexPath are hard-wired to be subdirectories of IndexedPath,
      3. RecentPath must be set to be a subdirectory of IndexedPath,
      4. ContribPath has disappeared, and
      5. HtdocsPath is a new directory with files served by the web server.
    • Tweak BridgeDB metrics file names.
    • Update to metrics-lib 2.9.0.

Changes in version 1.12.0 - 2019-10-18

  • Medium changes
    • Require Mockito 1.10.19 as dependency for running tests.
    • Archive BridgeDB statistics.
    • Update to metrics-lib 2.8.0.

Changes in version 1.11.1 - 2019-09-19

  • Minor changes
    • Update create-tarballs.sh to also produce bridge pool assignments tarballs.
    • Fix synchronization part of newly re-added bridge pool assignments module.

Changes in version 1.11.0 - 2019-09-19

Changes in version 1.10.0 - 2019-09-12

  • Medium changes
    • Changed local import of bandwidth files to include the parent directory name as @source annotation and to the filename.
    • Use Ivy for resolving external dependencies rather than relying on files found in Debian stable packages. Requires installing Ivy (using apt-get install ivy, brew install ivy, or similar) and running ant resolve (or ant -lib /usr/share/java resolve). Retrieved files are then copied to the lib/ directory, except for dependencies on other metrics libraries that still need to be copied to the lib/ directory manually. Current dependency versions resolved by Ivy are the same as in Debian stretch with few exceptions.
