[PATCH core-updates] gnu: ghostscript: Improve reproducibility of PDF document generation |
Date: |
Mon, 19 Jul 2021 11:45:07 +0000 |
Hi,
When trying to solve a reproducibility issue when generating the
PDF documentation of the txr software (see [1]), Paul Patience noticed
that ghostscript writes a creation date in the PDF even when the
GS_GENERATE_UUIDS environment variable is set to "0".
The attached patch updates 'ghostscript-no-header-creationdate.patch' to
fix this issue.
Given the amount of rebuilds caused by modifying ghostscript, this
should go to core-updates, but is core-updates in freeze state already,
or can I push this patch right now?
Note: Even with this patch, there are still some cases where PDF
generation by ghostscript is not reproducible (for reasons not related
to creation date), like groff-doc.

> LGTM, you can push to ‘core-updates’.
Done in db5962c68099f835350c24c8a3f889b9fa1f8a8e.
Thanks for the review.
> Was this submitted upstream?
No, in [1] upstream indicates explicitly that they don't want to
implement reproducible builds.
