+ Major changes between OpenPKG 1.3 and OpenPKG 2.0
+ =================================================
+
+ o Extensions to RPM 4.2.1:
+
+ --db-{build,rebuild,cleanup,fixate}
+ accurate removal of temporary files
+ -bb --short-circuit
+ ...FIXME...
+
+ o Upgraded from RPM 4.0.2 to RPM 4.2.1.
+
+ - Query Pattern Matching
+
+ RPM 4.2 now alows a glob(3) pattern matching on queries.
+ ("rpm -qa kde-*")
+
+ - Platform Identification:
+
+ We finally cleaned up the whole platform identification in RPM. The
+ new approach now is: <prefix>/lib/openpkg/platform is a program which
+ dynamically determines the "<arch>-<vendor>-<os>" id string for
+ the underlying platform. Wxample outputs are: ix86-pc-freebsd4.8,
+ ix86-pc-redhat9, sparc64-sun-solaris9, etc.
+
+ Then there is <prefix>/etc/openpkg/platform which is the once
+ determined platform id, loaded by RPM to internally provide the
+ macros %_host_{cpu,vendor,os} and %_host. Additionally, we adjusted
+ all other platform id related macros (%_target, %_arch, %_os, etc) to
+ directly depend on these macros. This way we have a new single point
+ of source for the official platform id.
+
+ - Bugfixes:
+
+ The upgrade from RPM 4.0.2 (status quo as of March 2001) to RPM 4.2.1
+ (status quo as of June 2003) is a major code change covering a two
+ year vendor development cycle. This means hundrets of bugs in RPM
+ were fixed and the code was partly refactored and cleaned up.
+
+ - Package Signatures:
+
+ RPM 4.2 now uses the BeeCrypt cryptography library for verification
+ of signatures. Previously one needed an externally available GnuPG.
+ GnuPG now is only needed for creating signatures. Additionally, RPM
+ 4.2 manages OpenPGP publuc keys in its RPM database similar to real
+ packages (they even can be seen as pseudo-packages "gpg-pubkey-XXXXX"
+ under query operations). The OpenPKG bootstrap (and also the regular
+ upgrade procedure) now especially imports the OpenPKG OpenPGP public
+ key into this database to make sure that one out-of-the-box can
+ verify signed packages. Finally, "rpm -qi" now especially displays
+ signature information, too.
+
+ - RPM Database, Berkeley-DB 4.1.24
+
+ RPM 4.2 now internally uses Berkeley-DB 4.1.24 instead of version
+ 3.2.4 which RPM 4.0 used. The old DB version 7 database files can
+ still be read without problems and on "openpkg" package upgrade,
+ the database is rebuilded and upgraded to DB version 8 files
+ automatically. Additionally, RPM 4.2 now managed more information
+ than RPM 4.0 and hence uses a few additional database files.
+
+ - Re-Packaging
+
+ RPM 4.2 now provides a nifty --repackage feature which can be applied
+ especially to the --erase operation. Before erasing the installed
+ package, RPM then first creates a corresponding binary RPM from
+ scratch. This later can be used to rollback the erase operation.
+ It just has to be remembered that the binary RPM resulting from
+ a "repackage" operation is both not identical to the original
+ binary RPM (because not all information was installed) and that the
+ resulting binary RPM usually has a wrong MD5 digest (so you have to
+ use --nodigest).
+
+ - POPT Upgrade
+
+ RPM 4.2 now uses an enhanced version of the POPT library, which
+ especially allows special "argument eating" markers "!#:+" to be
+ used in the rpmpopt file. This allowed us now to provide convinience
+ macros for %option handling on the command line:
+
+ --with foo => --define 'with_foo yes' => %option with_foo yes
+ --without foo => --define 'with_foo no' => %option with_foo no
+ --option with_foo bar => --define 'with_foo bar' => %option with_foo bar
+
+ - %files Improvements:
+
+ If the payload contains an OpenPGP public key, it can be added to
+ the RPM header with a new %files attribute "%pubkey". Additionally,
+ %exclude will now allow fully exclusion ("everything but"). Then
+ there is a new %dev(type,major,minor) directive to permit non-root
+ device files.
+
+ - rpmbuild(8):
+
+ A new command line tool rpmbuild(8) was introduced, providing the
+ official RedHat way of building packages by accepting all the -bX
+ options. Those options were removed from the rpm(8) command, too.
+ OpenPKG provides rpmbuild(8) also, but officially sticks with the
+ single command approach using just rpm(8) for all operations by
+ reenabling the legacy option mappings.
+
+ - Verification:
+
+ The "rpm --verify" operation was greatly improved and now checks more
+ details and is more accurate.
+
+ - Performance:
+
+ Noticable speed improvements were achieved for both query and install
+ operations.
+
+ - Transactions:
+
+ RPM internally now uses transactions for its operations (implemented
+ through data structure coloring) and supports full-state rollbacks in
+ case of problems.
+
+ - Concurrency:
+
+ RPM internally now uses the Berkeley-DB CDB feature for concurrent
+ access (read-only and read-write) to the RPM database. This
+ especially allows RPM packages to act (usually query) on the RPM
+ database concurrently (e.g. RPM called from within %post, etc)
+
+ - Querying:
+
+ New --queryformat header format modifiers were introduced: ":xml"
+ for dumping the content in XML (e.g. use --qf '[%{*:xml}\n]' to
+ dump header content in XML), ":base64" to dump in Base64 format and
+ ":armor" to dump in hex format.
+
+ - File Classification:
+
+ RPM 4.2 internally now uses the file(3) library for classifying files
+ and can use this on auto-dependency generation. OpenPKG does not use
+ this until now.
+
+ - Dependency Solving and Caching:
+
+ Although (still) not used by OpenPKG, RPM 4.2 has some limited
+ functionality (used by RedHat up2date) to cache binary RPM headers
+ locally and even store a full separate RPM database with package
+ information ("rpm --dbpath /path/to/somewhere --justdb -U *.rpm")
+ and then resolve dependencies through this information. This is
+ done with the --aid option which implements at least one of the 2
+ essential elements of a dependency solver. The 2 essential elements
+ are (a) locate a previously uninstalled package that satisfies a new
+ dependency. (b) upgrade an already installed package in order to
+ solve a problem. RPM currently does (a) only.
+
+ o New platform identification (%{l_platform})
+
+ ...FIXME...
+
+ o New release identification (%{l_openpkg_release})
+
+ ...FIXME...
+
+ o New RPM C API utility "rpm-config"
+
+ ...FIXME...
+
+ o Completely worked off Run-Command (RC) facility now also
+ for PLUS and EVAL packages.
+
+ ...FIXME...
+
+ o [TODO] Upgrade to Perl 5.8.1 and fully worked off extensional
+ Perl module packaging (module search order, vendor_perl, new
+ perl-openpkg.sh)
+
+ ...FIXME...
+
+ o [TODO] New website.
+
+ ...FIXME...
+
+ o thousands of bugfixes ;-)
+
+ ...FIXME...
