Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.4.0] - 2021-05-21

Counters of assertion passes and failures, simple status report printing, check for non-all-zero arrays, fixes to avoid compilation warnings.

Added

  • Counters atto_counter_assert_passes and atto_counter_assert_failures counting the amount of assertions atto_assert() or other aliases for it that failed or passed, to be able to see the progress through the test suite.
  • atto_report() to provide a simple one-line indication of what is the status of the 2 counters above at any point in the test suite, including at the very end.
  • atto_nzeros() which is the opposite of atto_zeros(), checking that there is at least one non-zero value in the array of bytes. Useful to check whether a memory location has been initialised to non-zero values, especially for random strings or data from an outside source we don't know the exact format of.
  • GitHub workflow scripts to build and self-test on different operating systems. Fancy badges in the readme included.

Fixed

  • CMake configuration now uses a more portable set of compiler flags, taken from LibAscon.
  • Some macro arguments did not have round brackets around them.
  • Self-test changed to avoid compilation warnings due to improper use of types (integers for float/double functions and signed/unsigned warnings).
  • Cast the length values passed to atto_zeros() to size_t to avoid warnings about signed/unsigned integer comparison.
  • Remove .idea folder from Git repo from now on.
  • Fixed some typos/missing words in the BSD 3-Clause license text file.
  • Renamed Doxygen build target to avoid name clashes.
  • Fix typo in Doxygen config, now it should properly exclude the test and source file.
  • Fixed self-test skipping some of the checks.

[1.3.1] - 2020-12-27

No changes in the code, only documentation.

Fixed

  • Missing home page of the Doxygen documentation (being the content of the Readme)
  • Missing title of the v1.3.0 release.

[1.3.0] - 2020-12-27

Clickable links to failed assertions!

Added

  • atto_true() which simply maps to atto_assert() to have an opposite of atto_false() with consistent naming.

Changed

  • The printed text in case of a failed testcase now combines the filename and the line together in the format like filename.c:42 with 42 being the line. This allows some IDEs to recognise it as a link to a specific code line and make them clickable for much easier testing and debugging.

Fixed

  • atto_zeros(x, len) supports any kind of address as x, even non uint8_t* thus allowing to scan arrays of other integers or floats or strings for zeros without explicitly casting them. They are converted to uint8_t* internally.

  • Replace Doxyfile with CMake building it instead. Add stricter options.

[1.2.0] - 2020-02-05

Two more macros, some project structure changes (new atto.c file, new src/ folder).

Added

  • atto_memneq(a, b, len), the negation of atto_memeq(), checks that two memory segments are not equal.
  • atto_zeros(x, len) checks that a memory segment is filled with zeros.

Fixed

  • Move atto_at_least_one_fail variable into new separate atto.c file. Required as importing atto.h file in many locations leads to many static copies of the same variable to be set, which means that different files see a different variable.
  • Move selftest into subfolder tst/, moved atto.h and atto.c into src/ Required as when incorporating this whole project (or repo) into another C project, the IDE may interpret selftest.c as part of the main project, while it's not relevant. With this trick, one can set the atto/src folder as the only relevant one.
  • Variety of minor fixes in the readme.

[1.1.0] - 2019-10-06

More specialized macros for operators and floats, simpler examples, self test.

Added

  • atto_false(x), the negation of atto_assert(), to avoid forgetting the ! when calling something like atto_assert(!x)
  • Equality, inequality and other comparision operators, in particular to avoid mistyping the operator, especially the == into an assignment = when calling something like atto_assert(a == b)
    • Equality atto_eq(a, b)
    • Inequality atto_neq(a, b)
    • Less-Than atto_lt(a, b)
    • Less-Equal atto_le(a, b)
    • Greater-Than atto_gt(a, b)
    • Greater-Equal atto_ge(a, b)
  • Floating point equality with a custom absolute tolerance
    • For floats atto_fdelta(a, b, abstol)
    • For doubles atto_ddelta(a, b, abstol)
  • Non-finite floating point values checks
    • Value is NaN atto_nan(x)
    • Value is +/- Infinity atto_inf(x)
    • Value is +Infinity atto_plusinf(x)
    • Value is -Infinity atto_minusinf(x)
    • Value is NaN or +/- Infinity atto_notfinite(x)
    • Value is anything but Nan or +/- Infinity atto_finite(x)
  • Proper self-test selftest.c of the whole Atto framework.
  • More compiler flags to check for errors during compilation of the self-test.

Removed

  • example.c test file. Instead a simpler example is provided within the Readme.
