--- Comment #8 from David Cook <dc...@prosentient.com.au> --- On ktd, I'm noticing /var/lib/ucf/cache/:etc:perl:XML:SAX:ParserDetails.ini ucfq --verbose /etc/perl/XML/SAX/ParserDetails.ini Configuration file Package Exists Changed /etc/perl/XML/SAX/ParserDetails.ini libxml-sax-perl Yes No In the postinst for the libxml-sax-perl Debian package, it calls "update-perl-sax-parsers" which runs the following: system("ucf", "--debconf-ok", "--sum-file", "/var/lib/libxml-sax-perl/ParserDetails.ini.md5sum", $tmpfile, $file); unlink $tmpfile or die("unlink $tmpfile: $!"); /usr/share/doc/ucf/examples/postinst also includes an example of using a temporary file with "ucf", so that sounds pretty good to me. -- I've done some hacking on "update-perl-sax-parsers" and the "ucf" data files to try to get the prompt I wanted. I used "sudo su -" to bypass "DEBIAN_FRONTEND=noninteractive" in the ktd env vars. (In ktd images, we should use ARG instead of ENV for setting this env var. I'll double-check whether or not I have an existing issue or PR for that...) Hacked files: - /usr/bin/update-perl-sax-parsers - /var/lib/ucf/cache/\:etc\:perl\:XML\:SAX\:ParserDetails.ini - /var/lib/ucf/hashfile dpkg-reconfigure libxml-sax-perl debconf: unable to initialize frontend: Dialog debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 78.) debconf: falling back to frontend: Readline update-perl-sax-parsers: Registering Perl SAX parser XML::SAX::PurePerl with priority 10... update-perl-sax-parsers: Updating overall Perl SAX parser modules info file... debconf: unable to initialize frontend: Dialog debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 78.) debconf: falling back to frontend: Readline Modified configuration file --------------------------- A new version (/tmp/61U6DAa6Rj) of configuration file /etc/perl/XML/SAX/ParserDetails.ini is available, but the version installed currently has been locally modified. 1. install the package maintainer's version 3. show the differences between the versions 5. show a 3-way difference between available versions 7. start a new shell to examine the situation 2. keep the local version currently installed 4. show a side-by-side difference between the versions 6. do a 3-way merge between available versions What do you want to do about modified configuration file ParserDetails.ini? -- Basically, it checks if the installed version and the ucf cached version match. If they match, then the upstream version is installed. If they don't match, then the sysadmin is prompted as above. I think that sounds pretty ideal. We could actually use that for a variety of generated Koha config files. -- Anyway, I think I better change to a different task now, but I'm curious to hear what people think! -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list Koha-bugs@lists.koha-community.org https://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
