ursadb v1.3.0

New features

Taints

Dataset tainting. Datasets with incompatible taints will never get merged.

• New command: dataset "xxx" taint "yyy" - adds taint yyy to xxx.
• New command: dataset "xxx" untaint "yyy" - removes taint yyy from xxx.
• New construct: select with taints ["xxx"] "stuff" - select that only
  looks in datasets with specified tags.

Iterators

Huge memory saver for large results. Store query results on disk, instead
of dumping them with json to the client.

• New command select into iterator "stuff" - select that returns iterator.
• New command iterator "itername" pop 123 - pops element from the specified
  iterator.

Performance

• Enable IPO for release builds.

Internals

• New lock modes - new coordinator command to lock iterator.
• Rewrite logging to spdlog, instead of using std::cout like savages.

Code quality, tests and CI

• New target format added to CMakeLists. make format will reformat the
  whole code. We also reformatted our code to match new style.
• DatabaseName introduced, code expected to be slowly rewritten to use it.
• We now run clang-format after every commit in our CI pipeline.
• Run make build and unit tests after every build in the CI.
• Build the docker image automatically in our CI pipeline.
• Create a automatic pipeline for building deb packages.
• Refactor cmake lists, and revamp the project sructure.
• Use std::thread instead of raw pthread in the network service code.
