[Mageia-dev] RFC: task-obsolete and README.*.urpmi enhancement

Wed Jan 4 16:53:40 CET 2012

Hello,
+
+We have recently discussed here about task-obsolete.
+http://www.mail-archive.com/mageia-dev@mageia.org/msg09762.html
+https://bugs.mageia.org/show_bug.cgi?id=3786
+
+I like the idea.
+But I think that we need to inform the user about the package(s) that we 
+will obsolete and remove on his system (and why: security, ..).
+So I tried to use README.*.urpmi to do this.
+But I found that currently, urpmi and rpmdrake don't handle very well 
+optional README.*.urpmi (%ghost); they always display information's 
+screen, even if the file doesn't exist.
+
+So, I propose here 2 enhancements for README.*.urpmi (POC patch for 
+urpm/install.pm, and task-obsolete.spec in attachment):
+
+1) add support for optional README.*.urpmi (%ghost in spec):
+This will allow to build this README.*.urpmi at install time in %pre, 
+%post or %trigger only when it's necessary.
+One use case from the recent past in my mind:
+we have no way to inform users that still use nspluginwrapper + i586 
+flashplayer on x86_64 (and only them), that this is now deprecated and 
+they should replace the i586 by the x86_64 flashplayer,
+https://bugs.mageia.org/show_bug.cgi?id=2146#c22
+https://bugs.mageia.org/show_bug.cgi?id=2146#c25
+
+2) handle README.*.(obsolete|deprecated).urpmi
+In order to display informations about the deprecated or obsoleted 
+package(s), I suggest to handle 2 new kinds of README.*.urpmi:
+- README."nameObsoletedPackage".obsolete.urpmi to inform about the 
+package we obsolete by task-obsolete
+e.g. java-1.6.0-sun*, https://bugs.mageia.org/show_bug.cgi?id=3101
+
+- README."nameDeprecatedPackage".deprecated.urpmi to inform about 
+package that we considere as deprecated, but we have no reason (no 
+vulnerability, security, ...) to force uninstallation (task-deprecated?).
+
+What do you think ?
+
+
