Notes for slime - reproducible builds result

Version annotated: 2:2.15-1
Identified issues:
Identifier: timestamps_in_pdf_content
Description The timestamp is not in the PDF metadata, but embedded in the actual content (text).
Note: Use timestamps_in_tex_documents instead, which is more specific, if the PDF was created
by a TeX/LaTeX document using \today macro.
Identifier: timestamp_in_info_file_created_by_makeinfo
URL https://bugs.debian.org/826158
Description the build date is included in the info file generated by makeinfo when the source texi file includes @today{}.
Identifier: captures_build_path
Description Captures build path, e.g., /build/1st/foo-42.0 v. /build/foo-42.0/2nd
.
Until early 2024 we varied the build path when testing packages from unstable
and experimental, which we have stopped doing now as the build path is recorded
as part of the environment and thus can be used when rebuilding.
.
This issue is kept here for the time being.
.
This issue is only for miscellaneous issues which need individual fixes,
please create new issues for specific issues, e.g. gcc_captures_build_path.
.
Here follows some general tips for packages using the standard GNU toolchain:
.
If using autoconf, make sure you call ./configure via a relative and not absolute path.
.
If your issue is related to using the `__FILE__` macro, or the recording of
--debug-prefix-map flags in non-GCC non-debugging output, this is what is
fixed by our patch mentioned above; you should not need to fix it
specifically in your package.
