metrics-web/CHANGELOG.md
Karsten Loesing 714b2ee0cc Rewrite insert_bwhist in SQL. 
The old PL/pgSQL version of this function made three lookups in the
bwhist table to 1) check whether a row already exists, 2) insert or
update the row, and 3) update the row once again with array sums. The
new SQL version uses the INSERT ON CONFLICT statement introduced in
PostgreSQL 9.5 (Debian stretch has 9.6, buster has 11). The
performance gain measured using metrics-test is impressive, computed
aggregates are equivalent.

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

  • Medium changes

    • Improve runtime performance of the hidserv module by storing extrapolated statistics even if computed network fractions are zero, to avoid re-processing these statistics over and over.
    • Extract directory authority bytes per day in the bwhist module.
    • Rewrite insert_bwhist in SQL to improve performance of the bwhist module.

  • Minor changes

    • Make Jetty host configurable.
    • Configure a base URL in order to turn ExoneraTor's permanent links into https:// links.
    • Set default locale US at the beginning of the execution.
    • Set default time zone UTC at the beginning of the execution.

Changes in version 1.3.0 - 2019-11-09

  • Medium changes
    • Start downloading and processing votes.
    • Add Apache Commons Math 3.6.1 as dependency.
    • Extend ipv6servers module to generate servers part of legacy module.
    • 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.
    • Remove Cobertura from the build process.
