[pdftex] Including \pdfsuppressptexinfo in stable branch

[Brian Quistorff]

Hello,

Would it be possible to include the \pdfsuppressptexinfo feature from the
trunk folder into the stable branch? It was implemented by patch 846 (
https://mailman.ntg.nl/pipermail/ntg-pdftex/2007-August/003171.html) on
revision 223. This would allow removing some differences between PDFs built
in different settings. In my case, this allows project members that share a
git repository to produce identical PDFs. Byte identical PDFs makes it
easier to include them in under version control as they aren't changing
inconsequentially every run. This feature compliments the previous work on
making dates and IDs deterministic.

Thanks,
Brian Quistorff

Sounds fine to me, but sarovar is dead. Thanh, can you get Heiko's
patch from what was
http://sarovar.org/tracker/?func=detail&atid=495&aid=846&group_id=106
perhaps? (Or, Heiko, if you read this and have the patch at hand, could
you just send it to me?)

By the way, in the area of reproducible builds, Thanh already installed
some changes from Debian to use a constant time in the output
(look around SOURCE_DATE_EPOCH). I realize that's only a subset of what
\pdfsuppressptexinfo was doing, but FYI anyway.

Best,
Karl

Thanh added \pdfsuppressptexinfo, and it is installed in
the TeX Live sources in r39718.

Dear Jean-Christophe,

We downloaded the latest package from your internet web site and installed
it (running "first-setup.bat"). Installation went fine.

You have installed the ConTeXt.
See http://wiki.contextgarden.net/Main_Page

The following is the simplest meaningless example of ConTeXt mkii,
where pdftex is used:

%
% test.tex
%
\starttext
Test
\stoptext

which is compiled by
mtxrun --script texexec test.tex

Nowadays usually ConTeXt means ConTeXt mkiv, where luatex is used.
In ConTeXt mkiv, the above example is compiled by
context test.tex

In order to use pdflatex, or pdftex, you may obtain
TeX Live, or MikTeX, assuming that you are playing on windows.

Best,
Akira
