Description Michal Jaegermann 2007-12-07 20:51:17 EST
Description of problem: An attached sample Postscript file is produced by acroread. On F7 with ghostscript-8.15 it produces a page with such text: "Warning: This form is not supported with the current version of Acrobat or Adobe Reader. Upgrade to the latest version for full support." An attempt to view this file with evince on F8 ends up with: Error: /undefined in eartomark Operand stack: --nostringval-- Execution stack: ..... (Full error ouput, the same for x86_64 and i386 attached too). With gv one gets just a blank window. Unfortunately there are various PDF files which are not handled by open source tools and acroread is sometimes required. An upshot of the above is that if one tries to print from acroread window then, with a default printer policy to abort jobs on errors, results are that attempts to print silently vanish. Version-Release number of selected component (if applicable): ghostscript-8.60-5.fc8 How reproducible: always

Created attachment 281821 [details] Postscript file which spooks ghotscript-8.60
Comment 2 Michal Jaegermann 2007-12-07 20:55:10 EST
Created attachment 281831 [details] errors from an attempt to view this PS with evince on F8
Comment 3 Michal Jaegermann 2007-12-08 13:18:26 EST
A check with rawhide ghostscript-8.61-5.fc9 and feeding a sample file to 'gs -q -dBATCH -dPARANOIDSAFER -dNOPAUSE -sDEVICE=lj4dith -sOutputFile=- -' command, like printing could do, brings the same kind of errors. Interestingly enough 'ps2ascii' nearly works. "Nearly" in that sense that it does produce a text from the attached PS file but it also has some additions; like "Wa rnig: ThsfomtupedwcvAbaR." and "Reader. Ul". The current workaround is to back off ghostscript to a version from F7 repositories and then viewing and printing does work. No recompilation required. Although "ps2ascii additions" are present too.
Comment 4 Sammy 2007-12-08 14:08:45 EST
In my testing ghostscript 8.61 (I have few more patches than Fedora) works fine so does the new gsview 4.9. Failing programs are: evince, kghostview, gv (just shows a blank page). My impression is that these programs make a mistake in invoking gs 8.61 in this particular case otherwise gsview 4.9 would not work either and version 4.9 was just announced to support gs 8.61. There must be something different.
Comment 5 Michal Jaegermann 2007-12-08 14:32:02 EST
> I have few more patches than Fedora Quite possibly they make this difference. When I am trying, with ghostscript-8.61-5.fc9, a command from comment #3 there is a long pause and after that "Error: /undefined in eartomark" and all that followup jazz. ghostscript-8.15.4-3.fc7 produced 19213 bytes of output in real 0m0.546s user 0m0.490s sys 0m0.042s
Comment 6 Sammy 2007-12-08 16:33:35 EST
Does gs itself show the file correctly? I do get the same error if I run comment #3 but not with gs alone and not with gv (EXCEPT turn DSC off under gv options) and gsview. Also, if I run: gs -q -dBATCH -dPARANOIDSAFER -dNOPAUSE -sDEVICE=lj4dith -sOutputFile=- file.ps seems to work! Clearly the error is coming from the way each application is feeding the file to gs. This is why some are working and some not. There may have been a change in gs or it is a bug. Investigation continues.....
Comment 7 Sammy 2007-12-08 16:42:48 EST
OK. I found this under ghostscript bugzilla: http://bugs.ghostscript.com/show_bug.cgi?id=689577 The workaround is somewhat involved. Someone needs to look into this.
Comment 8 Sammy 2007-12-08 17:01:26 EST
I filed bugs with cups and foomatic for the needed changes there. In the mean time the line: gs -q -dBATCH -dPARANOIDSAFER -dNOPAUSE -sDEVICE=lj4dith -sOutputFile=- -_ works fine (note the underscore after -). Since you are an evince user could you file a bug with them and direct them to this bug. Thanks
Comment 9 Michal Jaegermann 2007-12-08 21:17:04 EST
Yes, commands from comment #6 and comment #8 do work; at least for ghostscript-8.61-5.fc9. gs and gsx (that what I able to find; I guess that gsx is a gsview equivalent) show, on rawhide, my sample file. Thanks for bugs.ghostscript.com reference. I guess that it explains what is happening here. Contrary to some suggestions on ghostscript bugzilla turning off DSC in gv does not seem to have any effects; always a blank page. > Since you are an evince user ... Actually you can hardly accuse me of that. :-) I just found that evince provided a convenient way to demonstrate the problem. This is really not an evince bug but one in ghostscript.
Comment 10 Sammy 2007-12-09 11:30:00 EST
The fix for this was committed to ghostscript trunk. I am attaching the patch. However, this may come back at some point in the future. The fixes that add an ""_" after "-" are still good and may prevent a future problem but this is up to each packager to decide.
Comment 11 Sammy 2007-12-09 11:32:25 EST
Created attachment 282271 [details] Patch for fixing pipe problem
Comment 12 Michal Jaegermann 2007-12-09 13:27:27 EST
I do not know much about ghotscript internals but that fix smells awfully like a hack. Something else will drop into a file another eexec block instead of "the following eleven lines" from Adobe and the "magic constant" will not work in such case. Don't you think that this is a distinct possibility? OTOH a comment 17 from a discussion on ghostscript bugzilla does suggest that foomatic should use '-_' instead of '-' for stdin anyway (and the same applies for other non-interactive uses).
Comment 13 Sammy 2007-12-10 16:28:39 EST
I agree and urge foomatic to modify foomatic-gswrapper script as suggested as well as cups to modify pstoraster. Ghostscript has already modified their pstoraster and pstopxl scripts to use "-_" for keeps! Could we get some response for this bug? Thanks
Comment 14 Tim Waugh 2007-12-11 12:32:15 EST
New package built, should be in updates-testing soon.
Comment 15 Fedora Update System 2007-12-12 14:52:32 EST
ghostscript-8.61-4.fc8 has been pushed to the Fedora 8 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update ghostscript'
Comment 16 Michal Jaegermann 2007-12-12 19:04:13 EST
I am afraid that with ghostscript-8.61-4.fc8 I still see on my test file while trying gs -q -dBATCH -dPARANOIDSAFER -dNOPAUSE -sDEVICE=lj4dith -sOutputFile=- - the same errors as before. It does work if I will use '-_' for input but that we knew. Also evince spills familiar errors and both evince and gv show a blank page. OTOH 'gs test_file.ps' does produce an image of a page with an expected text displayed. So this did change. Not much yet ...
Comment 17 Sammy 2007-12-12 19:42:03 EST
I think he meant ghostscript-8.61-5.fc8
Comment 18 Michal Jaegermann 2007-12-12 20:00:47 EST
> I think he meant ghostscript-8.61-5.fc8 Well, comment #15 says ghostscript-8.61-4.fc8 and that is what I found in updates-testing. Granted, looking closer that package is a bit old but this is also what is listed in "Fedora updates-testing report" from today. Sigh!
Comment 19 Tim Waugh 2007-12-13 05:26:24 EST
Indeed, my mistake. I've pushed ghostscript-8.61-5.fc8 to the updates system now, and it should get into the next batch of updates. Sorry!
Comment 20 Fedora Update System 2007-12-15 12:49:17 EST
ghostscript-8.61-5.fc8 has been pushed to the Fedora 8 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update ghostscript'
Comment 21 Michal Jaegermann 2007-12-15 15:09:20 EST
> ghostscript-8.61-5.fc8 has been pushed .... WORKSFORME on various tests with samples which gave me troubles before. Although "testing" repos seem to lag quite a bit behind, despite of annoucements, so this was on a copy from koji. Thanks!
Comment 22 Fedora Update System 2007-12-20 14:52:54 EST
ghostscript-8.61-5.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
