Created attachment 298265 [details] [review]
Change the default of HTML_TIMESTAMP from YES to NO

"With free software, anyone can inspect the source code for malicious flaws.[...] The idea of “deterministic” or “reproducible” builds is to empower anyone to verify that no flaws have been introduced during the build process by reproducing byte-for-byte identical binary packages from a given source" https://wiki.debian.org/ReproducibleBuilds/About

In Debian there are about 300 source packages that are not byte for byte reproducible between different rebuilds because doxygen includes a timestamp. https://reproducible.debian.net/issues/timestamps_in_documentation_generated_by_doxygen_issue.html

We observed that 70% of these source packages do not explicitly set the HTML_TIMESTAMP variable. Thus, if doxygen would change the default of this variable to not generate timestamps, most of these packages will immediately become reproducible.

Please also consider implementing this for this other patch of mine: https://bugzilla.gnome.org/show_bug.cgi?id=744938

The attached patch changes the default of HTML_TIMESTAMP from YES to NO

Thanks, I'll include the patch in the next GIT update.
Comment 2 Dimitri van Heesch 2015-06-27 19:02:02 UTC
This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.8.10. Please verify if this is indeed the case. Reopen the
bug if you think it is not fixed and please include any additional information 
that you think can be relevant (preferably in the form of a self-contained example).
