[Till Kamppeter]

I have downloaded the Ubuntu package (the .tgz file with the sources) 
and were not able to rebuild the Ubuntu packages on my up-to-date Hardy 
system &4-bit PC).

After uncompressing the tarball I got the files:

opfc-pdf-filters_0.4-1ubuntu710.diff.gz
opfc-pdf-filters_0.4-1ubuntu710.dsc
opfc-pdf-filters_0.4-1ubuntu710_i386.changes
opfc-pdf-filters_0.4.orig.tar.gz

I have uncompressed them with

dpkg-source -x opfc-pdf-filters_0.4-1ubuntu710.dsc

and did a straight rebuild:

cd opfc-pdf-filters-0.4
dpkg-buildpackage -rfakeroot

and got

Manually compiling imagetopdf works without problems.

So it seems that there are problems with all Poppler-based programs.

In general, programs to be included in distros should not depend on the 
whole source code of another program. From the other programs you are 
usually using a library (libpoppler, libcups) and all which you need to 
compile code using the library are the .h files which are in the -dev 
packages of the libraries. So make the appropriate -dev packages a build 
dependency in your debian/control file and you will no need the whole 
source code.

Including the whole source code of another program raises a maintenance 
problem in distributions. If that other program has a bug, not only the 
package for that program has to be fixed but also your package. If many 
packages include the source code of one given program, a lot of packages 
need to be fixed to get one small bug out of the distro.

Also taking a program X, modify it a little bit to obtain a program Y 
and publishing this is not a good idea, as the source code is still 90% 
X and so a bug in X also requires fixing Y. Also here you should try to 
use libraries (like libpoppler). If this is not possible, for example if 
project X does not make the functionality of the program X available in 
a library, you should create a patch for the package X, which makes the 
build process of X create both the programs X or Y (or better let the 
user choose whether he wants to have X and/or Y) and submit it to the 
upstream project X.

Do you really need the full Poppler (or CUPS) source tree for your 
Poppler-based (or CUPS-based) filters? Or is it enough to have the 
header files? For libpoppler you need to install libpoppler-dev and you 
find them in /usr/include/poppler/ and for CUPS you need to install 
libcupsys2-dev and libcupsimage2-dev and you find the headers in 
/usr/include/cups. Running ./configure without "--with-...-source=..." 
should find the headers automatically.

Re: [Printing-architecture] PDF CUPS filter packages

[Till Kamppeter]

Thank you, now the package rebuilds correctly for me. Next step to fix 
now for you is to eliminate the necessity of full copies of the Poppler 
and CUPS source code in the package.

Another issue are the cost factors in the .convs files. They must 
prioritize the PDF workflow. Note here that lower cost factors give 
higher priority.

I suggest the following:

pdftopdf:
application/pdf         application/vnd.cups-pdf        33   pdftopdf

pdftoraster:
application/vnd.cups-pdf application/vnd.cups-raster    66   pdftoraster

imagetopdf:
image/gif               application/vnd.cups-pdf        50   imagetopdf
...
image/x-sun-raster      application/vnd.cups-pdf        50   imagetopdf

(all lines 50 as cost factor)

We will also need a pstopdf filter to handle PostScript input. This 
filter can be a simple script which can be easily derived from the 
pstoraster filter. It will need the following conversion rule:

pstopdf:
application/postscript   application/pdf                   0 pstopdf

We also need to add the following rule to make native PostScript 
printers working with the PDF workflow (the filter comes already with CUPS):

pdftops:
application/vnd.cups-pdf application/vnd.cups-postscript   0 pdftops


Also a problem are the PPD files shipped with the package. They need 
certain OpenPrinting Vector driver modules which do not ship with the 
package. The PPD files need to be moved into the packages which ship the 
driver modules, as otherwise a printer setup tool will list the 
appropriate printers but printing on them will not work. In addition, 
PPD files should not be put directly into /usr/share/ppd, but into 
/usr/share/ppd/<supplier>/<manufacturer>.


I have also run lintian and linda, reporting the following smaller 
issues with the package:

For the record, the "errors" were caused by telling gcc to treat
warnings as errors (see snippet below).  I have not checked the
opfc-pdf-filters sources but this is not the default gcc behaviour,
AFAIK.

  cc1plus: warnings being treated as errors

While I am generally inclined to do this myself, it is a bit of a
mixed blessing as not all gcc versions of all distribution flag the
same things as warnings.  If adding your own warnings to -Wall, you
will very likely compound the issue.

In this particular case, converting string constants to `char *`, I
would say it should be fixed.

Then you should file an STR for CUPS (http://www.cups.org/str.php, 
feature request for CUPS 1.4) with a patch for the current SVN snapshot 
which integrates this filter.

This looks like Poppler's API is incomplete. You should file a 
bug/feature request to Poppler so that they expose the missing 
functions. Or a feature request of making these filters part of Poppler. 
Supply a patch with the bug report/feature request.

Here you should also contact the Poppler project for either exposing 
missing API elements or making the filter part of Poppler.

The PDF printing workflow is more reliable than the PostScript workflow. 
So the printout is more reliable if pdftopdf and not pstops is used, 
even in the case of having incoming PostScript and a driver which only 
accepts PostScript. Then CUPS should do pstopdf->pdftopdf->pdftops to 
get reliable page management.

File a bug at bugs.ghostscript.com, telling that this operation is 
needed for the permitted action of PRINTING. Tell also that we are 
implementing the PDF printing workflow where pstops gets replaced by 
pdftopdf.

OK. Please find a solution with them, either via low-level API or by 
making the filters part of the Poppler project.

GS is executing this embedded code which probably makes the PostScript 
interpreter exit with this error. One could modify Ghostscript to not 
exit under certain circumstances, for example if the output is going to 
stdout or if GS is running as a system user. You should contact the 
Ghostscript developers about that.

Can you try to print this file from Evince? Does this work with the PDF 
workflow?

Can you post this PDF file or make it otherwise available for download? 
I would like to use it for testing.

Below is my talk with Ralph Giles (rillian), leader of Ghostscript (IRC: 
#ghostscript on Freenode) about the problem of DRMes PDF files. WDYT 
should we do?

---------------------------------------------------------------------

<tkamppeter> rillian, hi
<rillian> hi till. what's up?
<tkamppeter> I have a problem with the PDF printing workflow.
<tkamppeter> I want to do all page processing in a pdftopdf CUPS filter 
instead of pstops, to improve reliability for these operations.
<tkamppeter> So I replace PostScript by PDF as print job format.
<tkamppeter> Now there is the Adobe Reader, closed-source, so cannot be 
patched to output PDF instead of PS when printing.
<rillian> ok...
<tkamppeter> Seems to be no problem for CUPS. CUPS starts with a pstopdf 
filter, based on Ghostscript to get PDF out of the PS coming from Adobe 
Reader
<tkamppeter> works perfectly with unencrypted PDFs.
<tkamppeter> Now I have an encrypted PDF, allowed is only PRINTING the file.
<tkamppeter> In this case the Ghostscript called by the pstopdf filter 
does not convert the file backk to PDF, giving the following error:
<tkamppeter> This PostScript file was created from an encrypted PDF file.
<tkamppeter> Redistilling encrypted PDF is not permitted.
<tkamppeter> ERROR: /undefined in --get--
<rillian> like they say, DRM can't enforce copyright law accurately
<rillian> (although it shouldn't say /undefined in --get--; feel free to 
file a bug on that
<tkamppeter> The error seems to be generated by the following piece of 
code inserted in the PS:
<tkamppeter> %ADOBeginClientInjection: DocumentSetup Start "No Re-Distill"
<tkamppeter> %% Removing the following eleven lines is illegal, subject 
to the
<tkamppeter> Digital Copyright Act of 1998.
<tkamppeter> mark currentfile eexec
<tkamppeter> 54dc5232e897cbaaa7584b7da7c23a6c59e7451851159cdbf40334cc2600
<tkamppeter> .....
<tkamppeter> Something needs to be changed in Ghostscript so that one 
can print this file ...
<rillian> I'm not sure what you want
<rillian> a flag that says "no really, I'm being called as a component 
of a print chain"?
<rillian> can you not just print such files as postscript directly?
<rillian> do you really need to be adding special support for 
proprietary software in the CUPS workflow?
<tkamppeter> I want to replace PostScript by PDF as standard print job 
format, probably you have been on one of my Printing Summits where we 
have talked about that.
<rillian> tkamppeter: I'm aware of that
<tkamppeter> Especially I want to make the page management (N-Up, 
selected pages, booklets, ...) reliably working,
<tkamppeter> but also nice things as smaller jobs, transparency, high 
color depths, ...
<tkamppeter> Now I once let free apps output PDF instead of PostScript 
(this needs only some small bits changed in Qt and GTK)
<rillian> tkamppeter: the document contains code that prevents 
redistillation. I don't think it's our place to help with that.
<tkamppeter> so I need to add an exception to the CUPS workflow for this 
one proprietary app?
<rillian> that's what you're asking for
<rillian> at least, if you want such DRM'd documents to print
<rillian> if it wasn't clear, I sounds like the DRM in question is *in 
the postscript file*
<rillian> it's not ghostscript enforcing it, it's the file itself
<tkamppeter> As if GS would convert it happily back to PDF there would 
be no exception, all jobs run through pdftopdf and no exception in the 
CUPS filtering is needed.
<rillian> so we'd have to actively detect and circumvent the DRM code
<rillian> if it really is just a set of lines, it might be easier to 
have your pstopdf script do that before feeding it to ghostscript
<tkamppeter> Does this DRM code detect whether the output device is 
"pdfwrite" and then stops and otherwise lets the interpreter continue?
<rillian> I don't know how it works
<rillian> can you post the document somewhere?
<rillian> (I expect it's more general that checking for 'pdfwrite' since 
that's ghostscript specific. It probably looks to see if some distiller 
parameters are being respected.)
<tkamppeter> rillian, you mean that the pstopdf script filters out the 
added lines and to make the DRM guys happy to make pstopdf only 
executable by "lp" (the CUPS system user).
* behdad has quit ("Leaving.")
<rillian> tkamppeter: that would make it safer to ship under the DMCA, 
since you could claim it's only used when printing
<rillian> as long as it didn't do anything when the DRM said 'no 
printing' of course...
<tkamppeter> rillian, do you have encrypted PDFs in your regression 
testing repos? Try to convert them to PostScript with the printing 
function of Adobe Reader. Then look into the PostScript code.
<rillian> tkamppeter: personally I wouldn't try to handle this. Tell the 
user their (proprietary) software is adding DRM to the documents it 
prints, which the printing subsystem is not allowed to handle
<tkamppeter> What I can also do with these files is to define a new CUPS 
mime detecting this DRM code and in this case pass it through pstops. 
Assuming that such PostScript comes only from Adobe it will probably 
smoothly do page management with pstops.
* hawk_pdm has quit ("Leaving.")
<tkamppeter> Problem here is that pstops can not be dropped from later 
CUPS releases as long as Adobe does not adopt the PDF printing workflow.
<rillian> or drops their DRM :)
<rillian> but the former is more likely
* KaL_out has quit ("That's not a bug, but a feature")
<tkamppeter> My big problem is that when I switch a distro over to the 
PDF workflow many users will complain that the PDFs which they are 
allowed to print do not print any more.
<tkamppeter> Users will not switch to Linux when they cannot print 
downloaded PDFs which print under Windows.
<rillian> does the file not print from evince?
<tkamppeter> Koji Otani from OpenPrinting Japan has done the tests when 
he was packaging the CUPS filters.
<tkamppeter> rillian, I asked Otani-san now to try to print it from 
Evince. I can imaging that this will work with a later version of 
Evince/GTK which outputs the print data as PDF.
<rillian> it should work, certainly
<rillian> ok, the only restricted pdf I had handy also doesn't allow 
printing, so I don't have the ps output to look at
<rillian> however, evince was happy to print it, so I don't imagine it 
would have qualms about printing a PDF that did allow printing
<rillian> So in addition to my suggestion that you declare this 
Acrobat's problem, I'd offer that there is a work around of not using 
Acrobat

Still, that only results in warnings, not errors, unless -Werror is
given as above.

BTW, -Wno-write-strings seems to have been included in -Wall somewhere
around gcc-4.2.3.  It's a good thing (but annoying if you end up with
a few hundred places that need fixing ;-).

Anyway, as Till said, these are poppler issues (if all you did is make
some non-public poppler API public) and should be fixed upstream.

Hope this helps,

Including Poppler code in CUPS is no problem with the license. Poppler 
is GPL. Probably the problem is that he wants to have copyright on the 
full source to be able to also include it in closed-source software and 
he probably also does not want to duplicate the Poppler source code 
(therefore he also changed the pdftops filter to call the pdftops tool 
from Poppler or xpdf instead),

As your current PDF filters go deeply into the Poppler source code I 
think the best place for them is the Poppler project.

Can you talk with Mike about including only the imagetopdf filter, as it 
does not use Poppler and goes deeply into the CUPS code. Tell Mike that 
you would transfer copyright to him and agree with him that the filter 
gets into CUPS under the same license as CUPS itself.
