Motivations ----------- 1. To mitigate against a reason developers often cite for not writing `pure` procedures: their inability to produce output in normal execution. 2. To promote the enforcement of programming contracts. Overview -------- This assertion utility contains four public entities: 1. An `assert` subroutine, 2. A `characterizable_t` abstract type supporting `assert`, and 3. An `intrinsic_array_t` non-abstract type extending `characterizable_t`. 4. An `assert_macros.h` header file containing C-preprocessor macros. The `assert` subroutine * Error-terminates with a variable stop code when a caller-provided logical assertion fails, * Includes user-supplied diagnostic data in the output if provided by the calling procedure, * Is callable inside `pure` procedures, and * Can be eliminated at compile-time, as controlled by the `ASSERTIONS` preprocessor define. Assertion enforcement is controlled via the `ASSERTIONS` preprocessor macro, which can be defined to non-zero or zero at compilation time to respectively enable or disable run-time assertion enforcement. When the `ASSERTIONS` preprocessor macro is not defined to any value, the default is that assertions are *disabled* and will not check the condition. To enable assertion enforcement (e.g., for a debug build), define the preprocessor ASSERTIONS to non-zero, eg: ``` fpm build --flag "-DASSERTIONS" ``` The program [example/invoke-via-macro.F90] demonstrates the preferred way to invoke assertions via the three provided macros. Invoking assertions this way ensures such calls will be completely removed whenever the `ASSERTIONS` macro is undefined (or defined to zero) during compilation. Due to a limitation of `fpm`, this approach works best if the project using Assert is also a `fpm` project. If instead `fpm install` is used, then either the user must copy `include/assert_macros.h` to the installation directory (default: `~/.local/include`) or the user must invoke `assert` directly (via `call assert(...)`). In the latter approach when the assertions are disabled, the `assert` procedure will start and end with `if (.false.) then ... end if`, which might facilitate automatic removal of `assert` during the dead-code removal phase of optimizing compilers. The `characterizable_t` type defines an `as_character()` deferred binding that produces `character` strings for use as diagnostic output from a user-defined derived type that extends `characterizable_t` and implements the deferred binding. The `intrinsic_array_t` type that extends `characterizable_t` provides a convenient mechanism for producing diagnostic output from arrays of intrinsic type `complex`, `integer`, `logical`, or `real`. Use Cases --------- Two common use cases include 1. [Enforcing programming contracts] throughout a project via runtime checks. 2. Producing output in `pure` procedures for debugging purposes. ### Enforcing programming contracts Programming can be thought of as requirements for correct execution of a procedure and assurances for the result of correct execution. The requirements and assurances might be constraints of three kinds: 1. **Preconditions (requirements):** `logical` expressions that must evaluate to `.true.` when a procedure starts execution, 2. **Postconditions (assurances):** expressions that must evaluate to `.true.` when a procedure finishes execution, and 3. **Invariants:** universal pre- and postconditions that must always be true when all procedures in a class start or finish executing. The [example/README.md] file shows examples of writing constraints in notes on class diagrams using the formal syntax of the Object Constraint Language ([OCL]). Downloading, Building, and Running Examples ------------------------------------------- ### Downloading Assert ``` git clone git@github.com:berkeleylab/assert cd assert ``` ### Building and testing with `gfortran` #### Single-image (serial) execution The following command builds Assert and runs the full test suite in a single image: ``` fpm test --profile release --flag "-ffree-line-length-0" ``` which builds the Assert library (with the default of assertion enforcement disabled) and runs the test suite. #### Multi-image (parallel) execution With `gfortran` and OpenCoarrays installed, ``` fpm test --compiler caf --profile release --runner "cafrun -n 2" --flag "-ffree-line-length-0" ``` To build and test with the Numerical Algorithms Group (NAG) Fortran compiler version 7.1 or later, use ``` fpm test --compiler=nagfor --profile release --flag "-coarray=cosmp -fpp -f2018" ``` ### Building and testing with the Intel `ifx` compiler ``` fpm test --compiler ifx --profile release --flag -coarray ``` ### Building and testing with the LLVM `flang-new` compiler ``` fpm test --compiler flang-new --flag "-mmlir -allow-assumed-rank -O3" ``` ### Building and testing with the Numerical Algorithms Group (NAG) compiler ``` fpm test --compiler nagfor --profile release --flag "-fpp -coarray=cosmp" ``` ### Building and testing with the Cray Compiler Environment (CCE) Because `fpm` uses the compiler name to determine the compiler identity and because CCE provides one compiler wrapper, `ftn`, for invoking all compilers, you will need to invoke `ftn` in a shell script named to identify CCE compiler. For example, place a script named `crayftn.sh` in your path with the following contents and with executable privileges set appropriately: ``` #!/bin/bash ftn $@ ``` Then build and test Assert with the command ``` fpm test --compiler crayftn.sh --profile release ``` ### Building and testing with other compilers To use Assert with other compilers, please submit an issue or pull request. ### Running the examples See the [./example](./example) subdirectory. Documentation ------------- See [Assert's GitHub Pages site] for HTML documentation generated with [`ford`]. For further documentation, please see [example/README.md] and the [tests]. Also, the code in [src] has comments formatted for generating HTML documentation using [FORD]. ### Potential pitfalls of `call_assert` macros: The `call_assert*` macros from the `assert_macros.h` header file provide the attractive guarantee that they will always compile *completely* away when assertions are disabled, regardless of compiler analyses and optimization level. This means users can reap the maintainability and correctness benefits of aggressively asserting invariants throughout their code, without needing to balance any potential performance cost associated with such assertions when the code runs in production. Unfortunately, C-preprocessor macros do not integrate cleanly with some aspects of the Fortran language. As such, you might encounter one or more of the following pitfalls when using these macros. #### Line length limit Up to and including the Fortran 2018 language standard, compilers were only required to support up to 132 characters per free-form source line. Preprocessor macro invocations are always expanded to a single line during compilation, so when passing non-trivial arguments to macros including `call_assert*` it becomes easy for the expansion to exceed this line length limit. This can result in compile-time errors like the following from gfortran: ``` Error: Line truncated at (1) [-Werror=line-truncation] ``` Some compilers offer a command-line argument that can be used to workaround this legacy limit, eg: * `gfortran -ffree-line-length-0` aka `gfortran -ffree-line-length-none` When using `fpm`, one can pass such a flag to the compiler using the `fpm --flag` option, eg: ```shell $ fpm test --profile release --flag -ffree-line-length-0 ``` Thankfully Fortran 2023 raised this obscolecent line limit to 10,000 characters, so by using newer compilers you might never encounter this problem. In the case of gfortran, this appears to have been resolved by default starting in release 14.1.0. #### Line breaks in macro invocations The preprocessor is not currently specified by any Fortran standard, and as of 2024 its operation differs in subtle ways between compilers. One way in which compilers differ is how macro invocations can safely be broken across multiple lines. For example, gfortran and flang-new both accept backslash `\` continuation character for line-breaks in a macro invocation: ```fortran ! OK for flang-new and gfortran call_assert_diagnose( computed_checksum == expected_checksum, \ "Checksum mismatch failure!", \ expected_checksum ) ``` Whereas Cray Fortran wants `&` line continuation characters, even inside a macro invocation: ```fortran ! OK for Cray Fortran call_assert_diagnose( computed_checksum == expected_checksum, & "Checksum mismatch failure!", & expected_checksum ) ``` There appears to be no syntax acceptable to all compilers, so when writing portable code it's probably best to avoid line breaks inside a macro invocation. #### Comments in macro invocations Fortran does not support comments with an end delimiter, only to-end-of-line comments. As such, there is no portable way to safely insert a Fortran comment into the middle of a macro invocation. For example, the following seemingly reasonable code results in a syntax error after macro expansion (on gfortran and flang-new): ```fortran ! INCORRECT: cannot use Fortran comments inside macro invocation call_assert_diagnose( computed_checksum == expected_checksum, ! ensured since version 3.14 "Checksum mismatch failure!", ! TODO: write a better message here computed_checksum ) ``` Depending on your compiler it *might* be possible to use a C-style block comment (because they are often removed by the preprocessor), for example with gfortran one can instead write the following: ```fortran call_assert_diagnose( computed_checksum == expected_checksum, /* ensured since version 3.14 */ \ "Checksum mismatch failure!", /* TODO: write a better message here */ \ computed_checksum ) ``` However that capability might not be portable to other Fortran compilers. When in doubt, one can always move the comment outside the macro invocation: ```fortran ! assert a property ensured since version 3.14 call_assert_diagnose( computed_checksum == expected_checksum, \ "Checksum mismatch failure!", \ computed_checksum ) ! TODO: write a better message above ``` Legal Information ----------------- See the [LICENSE](LICENSE) file for copyright and licensing information.

Simple examples --------------- The [simple_assertions.f90] example demonstrates a precondition and a postcondition, each with an assertion that checks the truth of a logical expression based on scalar, real values. Derived type diagnostic data ---------------------------- See [derived_type_diagnostic.f90]. For reasons related to runtime performance, it is desirable to ensure that any computation required to extract diagnostic data from an object only take place if the assertion fails. This is one of the main motivations for allowing objects to be passed to the `diagnostic_data` argument of `assert`. The generic programming facilities planned for "Fortran 202y" (two standards after Fortran 2018) will ultimately provide the best way to facilitate the extraction of diagnostic data from objects by empowering developers to express requirements on types such as that the types must support a specific procedure binding that can be used to extract output in character form, the form that `assert` uses for its error stop code. For now, we impose such a requirement through an `as_character` deferred binding on the provided `characterizable_t` abstract type. Because it might prove problematic to require that a user type to extend the `characterizable_t` abstract type, the [derived_type_diagnostic.f90] example shows a workaround based on the class hierarchy described in the figure below. The figure shows a Unified Modeling Language ([UML]) class diagram with the `characterizable_t` abstract class, an example user's `stuff_t` class, and a `characterizable_stuff_t` class. The pattern expressed in the workaround aggregates the example user type, `stuff_t`, as a component inside the encapsulating `characterizable_stuff_t` type defined to extend `characterizable_t` for purposes of implementing `characterizable_t` parent type's deferred `as_character()` binding. The figure below also shows two constraints written in UML's Object Constraint Language ([OCL]). The constraints describe the precondition and postcondition checked in [derived_type_diagnostic.f90] and the context for those constraints. The UML diagram below was generated in the [Atom] editor [PlantUML] package from the PlantUML script in this repository's [doc] folder. ![Classes involved in Derived-Type Diagnostic Example](https://user-images.githubusercontent.com/13108868/130385757-6b79e5f1-5dec-440c-98f5-0f659c538754.png) Running the examples -------------------- ### Single-image execution ``` fpm run --example simple_assertions fpm run --example derived_type_diagnostic ``` where `fpm run` automatically invokes `fpm build` if necessary, .e.g., if the package's source code has changed since the most recent build. If `assert` is working correctly, the first `fpm run` above will error-terminate with the character stop code ``` Assertion "reciprocal: abs(error) < tolerance" failed on image 1 with diagnostic data "-1.00000000" ``` and the second `fpm run` above will error-terminate with the character stop code ``` Assertion "stuff_t%z(): self%defined()" failed on image 1 with diagnostic data "(none provided)" ``` ### Multi-image execution with `gfortran` and OpenCoarrays ``` git clone git@github.com/sourceryinstitute/assert cd assert fpm run --compiler caf --runner "cafrun -n 2" --example simple_assertions fpm run --compiler caf --runner "cafrun -n 2" --example derived_type_diagnostic ``` Replace either instance of `2` above with the desired number of images to run for parallel execution. If `assert` is working correctly, both of the latter `fpm run` commands will error-terminate with one or more images providing stop codes analogous to those quoted in the [Single-image execution] section. ## Derived-type diagnostic data output To demonstrate the derived-type diagnostic data output capability, try replacing the `i%defined()` assertion in the [derived_type_diagnostic.f90](./derived_type_diagnostic.f90) with `.false.`.

Assertion enforcement is controlled via the `ASSERTIONS` preprocessor macro, !! which can be defined to non-zero or zero at compilation time to !! respectively enable or disable runtime assertion enforcement. !! !! When the `ASSERTIONS` preprocessor macro is not defined to any value, !! the default is that assertions are *disabled* and will not check the condition. !! !! Disabling assertion enforcement may eliminate any associated runtime !! overhead by enabling optimizing compilers to ignore the assertion procedure !! body during a dead-code-removal phase of optimization. !! !! To enable assertion enforcement (e.g., for a debug build), define the preprocessor ASSERTIONS to non-zero. !! This file's capitalized .F90 extension causes most Fortran compilers to preprocess this file so !! that building as follows enables assertion enforcement: !! !! fpm build --flag "-DASSERTIONS" !! implicit none private public :: assert, assert_always #ifndef USE_ASSERTIONS # if ASSERTIONS # define USE_ASSERTIONS .true. # else # define USE_ASSERTIONS .false. # endif #endif logical, parameter :: enforce_assertions=USE_ASSERTIONS interface pure module subroutine assert(assertion, description, diagnostic_data) !!
