Units v0.4.0 Release Notes

Release Date: 2020-03-30 // over 1 year ago
  • Add a converter command line application and fix a few slow conversion issues and some other fuzz issues that came up recently, add isnormal operation for measurements, better test coverage for fixed_precise_measurement, some additional tests and static analysis checks.

    🔄 Changed

    • ➕ Added several tests run under Azure to remove deprecated image and add some new tests #40
    • ⚠ clears up several warnings from clang-tidy #41
    • the fuzzer now uses fuzz_measurement #42
    • ⚡️ update clang format to limit line length to 80 and allow reflowing comments #43
    • ➕ add clang-tidy checks for the tests and fix a few issues. #47

    🛠 Fixed

    • A few timeouts on the fuzzer- the fix was to generalize the multiplier insertion after ^ to accept multiple digits after the ^ instead of just ignoring it after more than one. #34
    • An asymmetry was observed in the unit equality from on the fuzzers, this resulted in some modifications of the cround_equal and cround_precice_equals functions. Also noted that the functions weren't aborting on exact floating point equality so were doing quite a bit of extra calculations. #34
    • ⏱ A timeout issue from fuzzing having to do with not injecting multiplies after [] in some circumstances. The fix was to be a little more refined as to which point to not inject the * and to do it in multiple stages so as to not rely on the partitioner so much. #35
    • 🛠 fixed_measurement and fixed_precise_measurement had incorrect subtraction operation in a few overloads. #39
    • 🛠 fixed a few initial issues from fuzz_measurement #42
    • Some more fuzzing generated issues with cascading powers #45
    • ⚠ A number of additional clang-tidy checks were added and the resulting warnings fixed #46
    • An issue from the fuzzer dealing with equation type units #51

    ➕ Added

    • ➕ added a converter command line application that can convert units on the command line #35
    • ➕ Added a file operation that can load user defined units from a file #36
    • ➕ Added is_valid methods for all measurement types #36
    • ➕ Added addUserDefinedInputUnit to add user defined units only on the input #36
    • The webserver gained a to_string option to use the internal to_string operations to simplify the measurement and units #37
    • The webserver and the converter gained an ability to handle * and <base> as the input unit to convert the measurement to base units. #37
    • Added to_string operation for uncertain_measurements #38
    • ➕ Added isnormal operation for measurement types #39
    • Added UNITS_CLANG_TIDY option to run tests with Clang tidy #41
    • ✅ Added fuzz_measurement fuzzer to test measurement_from_string #42
    • ➕ Added cpplint test to azure #43
    • ➕ Added a number of additional units from UDunits #44
    • ➕ Added several CI checks including CPPlint, and a series of CMAKE checks, and formatting checks #48,#49
    • ➕ Added a series of additional tests for coverage #50

Previous changes from v0.3.0

  • 📚 Continued work on cleaning up the library and starting to add main documentation, as well as adding more units and cleaning up string conversions and some additional tests. Additional fuzzing fixes and add a webserver for exploring conversions.

    🔄 Changed

    • Change the unit_data operators from '+', '-' to '*' and '/' so they actually match the operation they are performing #12
    • 🆓 Pow on measurements is a free function instead of operator #12
    • ⚡️ Update cmake policy configuration so it works with newer CMakes #31

    🛠 Fixed

    • ✅ Several issues that came from the fuzzer tests (#14, #18, #16, #19, #24, #28, #30)
    • Fixed the UNITS_HEADER_ONLY target so it actually works and add some tests for it #23
    • Update the cmake code so it correctly deals with and uses the CMAKE_CXX_STANDARD option #22
    • ⚠ Some strict aliasing warnings on gcc 6 #26

    ➕ Added

    • ➕ Added pow and root functions to measurements #7
    • ➕ Add sqrt function which is a wrapper function around the root function for measurements and units #8
    • ➕ Added uncertain measurment class for dealing with uncertainties #9, later modified in the primary method of uncertainty propagation#32
    • ➕ Added a webserver for doing conversions through an html based interface #11
    • ➕ Added a docker file for doing fuzzing #16
    • ➕ Added initial set of documention on readthedocs.io #25,#27

    ✂ Removed

    • member methods of pow and root for measurements
