The bundled (reference) implementation was of somewhat mixed quality and
it failed to follow standard in multiple places. This commit replaces
it with a new one, written from scratch to follow the standard as close
as possible.
* module/srfi/srfi-64/testing.scm: Delete file.
* module/srfi/srfi-64.scm: Replace with new implementation.
* am/bootstrap.am (srfi/srfi-64.go): Remove extra dependencies.
(NOCOMP_SOURCES): Remove srfi/srfi-64/testing.scm.
* test-suite/tests/srfi-64-test.scm
("8.6.1. Simple (form 1) test-apply")
("8.6.2. Simple (form 2) test-apply"): Adjust tests to follow the
specification.
---
The current implementation of SRFI-64 is buggy and does not even follow the
specification in many places. This blog post[0] lists some of the bugs found.
This commit it by a new one written from scratch, that tries to solve both of
those problems.
The code library was tested with GNU Guix (probably biggest user of SRFI-64?)
and it works. There are only 4 tests that used to pass and do not with a new
implementation. In all of those cases, the bug in the test itself was masked by
non-compliance of the previous SRFI-64 implementation. More details here [1].
Tests in Guile (srfi-64-test.scm) did require two changes, the test code does
not (in my opinion) follow the specification. Since spec says
> Any skip specifiers introduced by a test-skip are removed by a following
> non-nested test-end.
The test-ends on lines 729 and 747 are nested, they are not top-level, so the
skip specifier should not be cleared. But I am opened to debate on this one.
During writing the implementation, I produced many (over 300) test files which
are available here[2]. I am not sure whether to have them in this commit as
well. Opinions?
Last remaining point to note is that there is some additional functionality not
covered by the specification included (define-test, ...). I can remove it, by I
consider it useful. Documentation is currently lacking, but that is
intentional, since #71300 is not accepted yet, and logically it would belong in
there.
