Request for testing/comments -- import of new dialog/libdialog

As part of work on a new installer, I would like to update the base system dialog and libdialog to the newer one provided by Thomas Dickey (http://invisible-island.net/dialog/, ports as devel/cdialog). This is a much nicer, fuller featured version of dialog that simplifies the creation of new dialog-using tools (a longstanding impediment to a new versions of sade, sysinstall, etc.), and is under a marginally better license (LGPL2 instead of GPL2). Patches to effect the import can be found at: - http://people.freebsd.org/~nwhitehorn/libdialog-update.diff What the patches do: - Replaces dialog(1) with a new version. All command-line options of the old dialog except --fstree are accepted by the new dialog, and the ports options framework continues to work without modification. - Renames libdialog to libodialog (old dialog). The new dialog library has a much more pleasant API than the old one -- which directly implies that it has a substantially different API. Until sysinstall, sade, and tzsetup are replaced or rewritten, we need to keep the old library around. - Modifies sysinstall, sade, and tzsetup to link to libodialog instead of libdialog. - Deletes all man pages and examples associated with libodialog. This is deprecated code. - Installs new dialog library as libdialog - Bumps __FreeBSD_version to 900030 Layout of new files: - /usr/src/contrib/dialog -- contents of 20100428 release of dialog (the same as the current ports version) - /usr/src/gnu/lib/dialog -- new dialog library - /usr/src/gnu/lib/libodialog -- old dialog library - /usr/src/gnu/usr.bin/dialog -- new dialog binary I would appreciate any comments or adverse test results. If I hear nothing, I plan to commit this on Wednesday, January 12, one week from today. -Nathan
