runlibfileifexists patch from OpenSUSE none

Description Mitchell Berger 2010-07-02 00:34:42 UTC 
Description of problem:
The spec file for the ghostscript package creates the following
three files in /etc/ghostscript/8.71:
  cidfmap.local
  CIDFnmap.local
  Fontmap.local

The files under /etc/ghostscript are important because they are
the only ones marked as %config(noreplace), and so if you make
customizations to the system-wide files in
/usr/share/ghostscript/8.71/Resource/Init, they may be clobbered
if the upstream version of the file changes.

The system-wide cidfmap and CIDFnmap files contain lines like
these at the end:

% must be at the bottom of line to allow people overriding everything.
(cidfmap.local) .runlibfileifexists

% must be at the bottom of line to allow people overriding everything.
(CIDFnmap.local) .runlibfileifexists

No such line exists at the end of the global Fontmap file.  As a
result, making customizations in the obvious place (the
/etc/ghostscript/8.71/Fontmap.local file that the package helpfully
creates for you) results in your customizations never being read
in by gs.

Version-Release number of selected component (if applicable):
8.71-6.fc11.x86_64, 8.71-9.fc13.x86_64, and presumably also the
current versions in F12 and Rawhide

Steps to Reproduce:
1. yum install ghostscript strace
2. strace gs >/tmp/gstrace 2>&1
3. search for Fontmap in /tmp/gstrace with your favorite editor
   and note that several locations including /etc/ghostscript and
   /etc/ghostscript/8.71 are searched for a file called Fontmap,
   but Fontmap.local is never tried
  
One way to tackle this would be to patch the upstream Fontmap
file to add something like this to the end of the global file:
(Fontmap.local) .runlibfileifexists
I recommend this solution.

Another approach would be to discontinue creating the
/etc/ghostscript/8.71/Fontmap.local file and instead create
one named Fontmap.  However, all systems with ghostscript
already installed may still have the Fontmap.local file present
and be confused when they try to use it.
Comment 1 Tim Waugh 2010-09-03 10:58:04 UTC 
The patch to get ghostscript to read Fontmap.local was dropped after ghostscript-8.15.4-3.fc7.  I think that was just a mistake at the time -- those files were reorganised upstream.

Thanks for reporting it.

Comment 6 Henry Kroll 2010-09-05 03:51:25 UTC 
Ghostscript-8.71-15.fc14 won't print anymore in Rawhide.

$ /usr/lib/cups/filter/pstoraster
Fontmap entry for Fontmap.local ends prematurely!  Giving up.

It DOES work, however, if you change

(CIDFnmap.local) .runlibfileifexists
to
(Fontmap.local) .runlibfile

in /usr/share/ghostscript/8.71/Resource/Init/Fontmap

or remove the line entirely.
Comment 7 Henry Kroll 2010-09-05 03:52:05 UTC 
I mean change (Fontmap.local) .runlibfileifexists to (Fontmap.local) .runlibfile

For me "asy -tex pdflatex xxx.asy" failed as above, fixed by commenting out the mentioned line.

AFAIU, the message means that the file is tuncated, i.e., just an empty file won't do. If it is shipped/used, it should be correct.

runlibfileifexists patch from OpenSUSE

I don't think the current runlibfileifexists patch in Fedora actually works due to the way fontmap files are loaded by gs_fonts.ps.

I found OpenSUSE's runlibfileifexists patch also modifies gs_fonts.ps to handle fontmap files that use runlibfileifexists.

http://www.mirrorservice.org/sites/download.opensuse.org/update/11.3/rpm/src/ghostscript-library-8.70-15.1.1.src.rpm/ghostscript-8.60-runlibfileifexists.dif?extract=true
Comment 10 David 2010-09-07 07:59:45 UTC 
This wont print in FC13 either:

ghostscript           i686      8.71-15.fc13        updates-testing      4.5 M
ghostscript-cups      i686      8.71-15.fc13        updates-testing       44 k

I found another bugzilla on this:

https://bugzilla.redhat.com/show_bug.cgi?id=630423

Maybe someone merge these bugs?
Comment 11 jd1008 2010-09-08 00:32:16 UTC 
On F13, I  have

ghostscript.i686         8.71-15.fc13 @updates-testing                          
ghostscript-cups.i686    8.71-15.fc13 @updates-testing                          
ghostscript-devel.i686   8.71-15.fc13 @updates-testing                          
ghostscript-fonts.noarch 5.50-23.fc12 @anaconda-InstallationRepo-200911081854.i386/12

I ran

$ gs -q -dNOPAUSE -dNODISPLAY -dBATCH -dDELAYBIND -g2448x3168 -r288 -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -c 0 0 translate -sTraceFile=/sdb3/home/jd/.scribus//ps.out -sExportFiles=/tmp/Document--XXX /usr/lib/scribus/import.prolog /tmp/XXX.pdf -c flush cfile closefile quit 

Fontmap entry for Fontmap.local ends prematurely!  Giving up.

So, even with the latest patches in 8.71-15, the bug remains.

FYI:

$ ls -l  /etc/ghostscript/8.71/Fontmap.local
-rw-r--r-- 1 root root 0 Sep  3 05:06 /etc/ghostscript/8.71/Fontmap.local

Zero length file. Why so??
The updates were installed a few days ago.
Comment 12 Joachim Frieben 2010-09-10 04:59:15 UTC 
This is probably wrong (ghostscript-8.71-15.fc14):

> ls -l /etc/ghostscript/8.71/
total 0
-rw-r--r--. 1 root root 0 Sep  3 14:15 cidfmap.local
-rw-r--r--. 1 root root 0 Sep  3 14:15 CIDFnmap.local
-rw-r--r--. 1 root root 0 Sep  3 14:15 Fontmap.local
Comment 13 Adam Tkac 2010-09-13 09:13:47 UTC 
Fix for this issue breaks also /usr/bin/ps2pdf command and it's currently impossible to build nasm package. When I revert from ghostscript-8.71-15.fc15 to ghostscript-8.71-14.fc15 everything is OK. Fix suggested in comment #6 also helps.

Thanks Edward, I think you hit the nail on the head there.  I've included the extra part of the patch in these respun packages.

I confirm that it is fixed in F13.

Comment 25 Alan Stern 2010-10-22 20:45:19 UTC 
In ghostscript-8.71-16.fc12 the "file" command no longer works correctly if -dSAFER is set.  I haven't tried using it much lately, so the problem may have crept in one or two releases earlier.

Example showing the problem:

[stern@iolanthe PS]$ rpm -qf `which gs`
ghostscript-8.71-16.fc12.i686
[stern@iolanthe PS]$ ls -l spiral.ps
-rw-rw-r-- 1 stern stern 2854 1999-03-02 14:50 spiral.ps

Comment 26 Tim Waugh 2010-10-25 11:35:44 UTC 
Ah, that might be the cause of bug #642427.
Comment 27 Alan Stern 2010-10-25 14:20:34 UTC 
Yes, it looks that way.  I originally ran across this problem in a similar setting; a "run" command that had worked previously now fails.

Over the weekend I found an old copy of the 8.71-7 release.  It did not have this problem.  I don't know where to find any intermediate releases, but probably you can test them just as easily as I can.
Comment 28 Tim Waugh 2010-10-25 15:51:37 UTC 
The cause is that we use a different (more secure) build default in ghostscript now which is equivalent to the command line option "-P-".  To allow reading files from the current directory, use the command line option "-P" (or "-I.").
