Bug#658258: Cups 1.5.0-16 breaks plain text printing
Hello, sacrificial-spam-addr...@horizon.com [2012-02-01 10:15 -0500]: The split off of a separate cups-filters package omits the texttops command which is called for in /etc/cups/mime.convs. Well, it actually was deliberately dropped, as cups has used an internal PDF workflow for a long time already. # grep texttops /etc/cups/mine.convs application/x-cshell application/postscript 33 texttops This is a local configuration file, not shipped by cups. So this does not break the package for everybody, but nevertheless is a rather important upgrade issue. But I don't want to argue about the severity of the report, we need to fix it one way or the other anyway. There could be a debconf warning, but I think it would be better to reintroduce a simple texttops shell wrapper which more or less does texttopdf | pdftops. Till wanted to look into this. You'd think it would be easy enough to log an error message like execve: /usr/lib/cups/filter/texttops: No such file or directory to bestow upon the humble sysadmin a clue as to *why* the document format is not supported. Amen.. :/ There should be a log message somewhere explaining the sequence of filters that cups chooses to apply, and detailed error output if any of them fail. I think it does when you do cupsctl --debug-logging.

# grep texttops /etc/cups/mine.convs application/x-cshell application/postscript 33 texttops This is a local configuration file, not shipped by cups. So this does not break the package for everybody, but nevertheless is a rather important upgrade issue. But I don't want to argue about the severity of the report, we need to fix it one way or the other anyway. Um! That's very odd. dpkg -L cups and dpkg -S /etc/cups/mime.convs agree that the file is owned by the cups package. But you're right, it's not part of the contents of the current cups_1.5.0 packages. How the hell did *that* happen? Does it consitute a bug or misfeature in dpkg? This might be some historical leftover from an old version or something. (The Debian installation has been continuously tracking unstable since 1999 or so.) Unfortunately, my archive of old binary packages got trashed recently, so it's hard to check history. There could be a debconf warning, but I think it would be better to reintroduce a simple texttops shell wrapper which more or less does texttopdf | pdftops. Till wanted to look into this. You'd think it would be easy enough to log an error message like execve: /usr/lib/cups/filter/texttops: No such file or directory to bestow upon the humble sysadmin a clue as to *why* the document format is not supported. Amen.. :/ Hopefully the rant tag helped keep it from feeling too much like a personal attack. There should be a log message somewhere explaining the sequence of filters that cups chooses to apply, and detailed error output if any of them fail.
