[ANN] poldek 0.19.0

[Pawel A.Gajda]

0.19.0 (major enhancements release; not released yet, not usable yet)

I) Source repositories
* repositories code has been totally rewritten in the modular, 
  plugin-like way, so is is quite easy to add support for new 
  formats. 

  Currently supported formats:

  name   caps description
  -----------------------
  pndir  rwu  Native poldek's index format (NEW)
  pdir   rwu  Native poldek's index format prior to 0.20 version
  dir    r--  Dynamic index built by scanning directory for packages
  hdrl   r-u  File with raw RPM package headers; used by apt-rpm
  rpmdb  r--  RPM package database (NEW)
  yum    r-u  Yum index format (NEW)
  ('rwu' stands for if index is able to read, write and update)

* new 'pndir' is the default format now. It is based on tndb (cdb 
  like) DBM library. To save bandwidth package descriptions 
  (Description, Summary, etc) are stored in 2 separate files:
  first named packages.ndir.dscr with common (BuildHost, Distribution, 
  etc) and "C" descriptions and second with all i18n 
  .dscr file per available language). 

* 'hdrl' aka 'apt' format are update-able now. 

* repository indexes could be created in many formats at once
  (using --mkidx-type=TYPE[,TYPE]), ex:

  $ poldek -s /foo/bar --mkdix --mkidx-type=pdir,pndir

* indexes may be created from any index format, i.e conversion to
  to another format is supported, ex:
  $ poldek --st apt -s /foo/bar --mkidx=/ala/ma --mkidx-type=pdir

* (re)creation of native poldek's indexes (pdir, pndir) is much faster now 
  -- package headers are not loaded at all if package's file modification 
  time is the same as saved one in existing index.


II) Installation related

* uninstallation code has been rewritten, --erase and 
  'uninstall' command work as expected now

* poldek can perform 'to repository' installation, i.e packages
  are copied from source to destination repository with full
  dependency checking, ex:

  $ poldek -n ...  --install-dest /var/foo/rpms-repo --upgrade-dist -v
  $ poldek -n ...  --install-dest-dn name --upgrade-dist -v


III) Interactive mode

* mode's commands are available without mode itself, i.e
  one can execute interactive commands from command-line:
  
  $ poldek -C ls 
  $ apoldek install libfoo-0.1-1

* aliases are defined in external configuration file 
  (Mariusz Mazur <mmazur a kernel pl>)

* commands may be piped, ex:
  poldek> rsearch /poldek/ | ls -l
  package                                build date        size
  poldek-0.18.6-19                       2004/09/15 21:22  421.0 KB
  poldex-0.17.4-1                        2004/08/17 22:12   47.0 KB
  2 packages, 468.0 KB

* external commands are supported too:
  poldek> rsearch /pol/ | grep ^pol
  polcnv-2.2-3
  poldek-0.18.6-19
  poldex-0.17.4-1
  policy-1.6-2


IV) Configuration file 

* multi word variables are written with spaces or underscore separator, i.e:
  both forms "this is = foo" and "this_is = foo" are valid. 

* default location of configuration file has been changed to 
  "${_sysconfdir}/poldek/poldek.conf", old /etc location is still supported. 

* configuration file format has been changed to ini-like one. Sources and 
  external file getters should be configured in its own sections "source" and 
  "fetcher", see sample configs. Old configuration format is still supported.

* environment variables in config files are expanded (ex: cachedir = $HOME/.cache)

* macro like expansion has been added to make configuration easier to read,
  ex: 

 _pld_arch   = i686
 _pld_prefix = ftp://ftp.pld.org.pl/dists/ra
 _ra_idxtype = pdir

 # PLD 1.0 (Ra)
 [source]
 type  = %{_ra_idxtype}
 name  = ra 
 path  = %{_pld_prefix}/PLD/%{_pld_arch}/PLD/RPMS/

* %include macro has been added, included file may be remote too, ex:

   _pld_prefix = ftp://ftp.pld.org.pl/dists/ra
  %include %{_pld_prefix}/source.conf

  Included remote files once downloaded are stored in cache directory, 
  to resynchronize them with it's remote copy use --upconf option. 

* support for APT sources configuration has been added; by default
  /etc/apt/sources.list is loaded if user configuration ($HOME/.poldekrc) 
  doesn't exist. To load it with personal config too, put 
  "load apt sources list = yes" to config.

V) General 

* removed and changed options and switches; all obsoleted opts are still 
  supported *except* "-f" (not important IMO). Changes:
  -f, --fast               => --skip-installed
  --mkidxz                 => --mkidx           (compression is on by default)
  --sidx, --sdir, --shdrl  =>                   (use --st=TYPE -s instead)
  --unique-pkg-names       => --uniq
  --shcmd                  =>                   (use -C or run ipoldek)
