76       
77        - Fixes some problem for printers which directly go from
78          "idle" to "warmup" and never to "printing" before
79          returning to "idle".
80         
81        - Some permissions settings may have prevented cupspykota
82          from parsing cupsd.conf, this is now fixed.
83         
84    - 1.22alpha2 :
85   
86        - Introduction of the web enabled print quote generator.
87

103       
104        - Updated some translation files.
105       
106    - 1.21beta2 :
107   
108        - Fixed an LPRng specific bug.
109       
110        - Several improvements on stability issues with manually modified

116   
117        - Prepared translation files for next release.
118       
119    - 1.21alpha27 :
120   
121        - Allows software() (no arguments) to the software accounting
122          directive. This saves a lot of CPU since the job is not
123          parsed again : the precomputed size is used directly in this
124          case.
125         
126        - epykota's --prototype option now works fine with accounts
127          limited by balance.
128         
129    - 1.21alpha26 :
130   
131        - Fixed the handling of the 'maxdenybanners' directive.
132       
133        - Introduced the 'denyduplicates' directive.
134       
135        - Fixed some database related glitches.
136

138   
139        - The job's size is now always precomputed, even when
140          'enforcement' is not set to 'strict'.
141         
142        - Introduction of the new 'trustjobsize' configuration directive
143          to workaround some problematic printers. See the sample
144          configuration file for details.
145         
146    - 1.21alpha24 :
147   
148        - Big database structure changes. An upgrade script
149          is now included for PostgreSQL. LDAP users may just
150          want to copy the new schema in place.
151         
152        - edpykota now recognizes the -o | --overcharge command line
153          option to set an overcharging or undercharging factor
154          on each print job's cost for a particular user.
155         
156        - repykota's output format has changed an is not limited to 
157          80 characters wide anymore. People who used to parse
158          repykota's output in their own tools are strongly advised
159          to parse dumpykota's output instead.
160         
161        - Introduction of the new 'maxdenybanners' configuration directive
162          to allow up to N (the directive's value) deny banners to be
163          printed even if the print account is forbidden to print.
164         
165        - Better detection of the number of copies in the PostScript parser.
166       
167    - 1.21alpha23 :
168   
169        - Traditional Chinese translation added.
170   
171        - Several fixes and performance improvements with the LDAP backend.
172       
173    - 1.21alpha22 :
174   
175        - edpykota's --delete command line option doesn't consider
176          '*' to be the default argument anymore :-)
177         
178    - 1.21alpha21 :
179   
180        - dumpykota.cgi can now be run as a normal user as opposed to
181          a PyKota administrator. No read access to pykotadmin.conf is
182          necessary anymore. This CGI scripts now honors the REMOTE_USER
183          environment variable just like printquota.cgi does, see
184          the file cgi-bin/README for details.
185          The command line tool dumpykota must still be run by a PyKota
186          administrator.
187         
188        - Fix exception's name error due to a change in recent versions
189          of PygreSQL.   
190         
191    - 1.21alpha20 :
192         
193        - Big bug fix wrt the datelimit field which was never reset.
194         
195    - 1.21alpha19 :
196   
197        - Introduction of the new dumpykota.cgi CGI script, which
198          allows third party tools like phpPrintAnalyzer to be
199          interfaced in real time with PyKota. To use it you
200          may have to change your web server's configuration,
201          please see pykota/cgi-bin/README
202         
203    - 1.21alpha18 :
204   
205        - Now dumpykota can dump the job history into CUPS' page_log
206          format (even when the printing system is LPRng). This allows
207          people to use tools like PrintAnalyzer or phpPrintAnalyzer
208          (two completely different beasts) with PyKota.
209         
210    - 1.21alpha17 :
211     
212        - Fixed field type's name in XML dumps.
213       
214        - Now drops priviledges to user 'pykota' when launched as root
215          (directly or as a CUPS backend), if such an user exists.
216         
217        - Fixed PCL3/4/5 parser for some drivers' output.
218       
219    - 1.21alpha16 :
220   
221        - fixed several recently introduced bugs in LDAP backend code,
222          thanks to Matt Hyclak.
223         
224    - 1.21alpha15 :
225     
226        - Normalized field names between LDAP and PostgreSQL backends
227          in dumpykota's output.
228         
229        - dumpykota filtering capabilities are now supported within
230          the LDAP backend too.
231         
232    - 1.21alpha14 :
233   
234        - dumpykota now supports extended filtering possibilities
235          with the PostgreSQL backend (LDAP support will come soon).
236         
237    - 1.21alpha13 :
238   
239        - Added a --debug command line option to pkpgcounter, so
240          that people may see what really happens, and what will
241          be available in the future :-)
242         
243    - 1.21alpha12 :
244   
245        - Fixed a bug with non standard pkbanner command lines.
246       
247        - Now logs as errors the differences between precomputed and
248          computed job sizes. **CUPS only for now**
249         
250    - 1.21alpha11 :
251   
252        - Now user and group print quota entries can be stored directly
253          below the user or group with the LDAP backend, using them
254          as branches. Thanks to Stefan Wold for the patch.
255          See the sample configuration file for details.
256         
257        - TLS is now supported with the LDAP backend. Thanks to Stefan
258          Wold for the patch.
259          See the sample configuration file for details.
260         
261        - edpkota now accepts the -U | --used value command line argument
262          to preset the page counters to an initial value. Thanks to
263          Wilson Roberto Afonso and Matt Hyclak for the patch.
264         
265    - 1.21alpha10 :
266   
267        - Now automatically reconnects up to three times if the LDAP server
268          returned an error, possibly due to a timeout.
269         
270    - 1.21alpha9 :
271   
272        - Now searches the configuration files in 'pykota' system user's
273          home directory. The 'pykota' system user and group have
274          to be created by the system administrator, and given
275          sufficient permissions to PyKota's configuration files.
276         
277    - 1.21alpha8 :

319         
320    - 1.21alpha1 :
321   
322        - added an IPP messages miniparser. Extraction of the client
323          hostname is now considered to be fiable, at least until
324          the CUPS developpers change something...
325       
326    - 1.20 :
327   
328        - Version number changed.
329

340          in the history.
341         
342        - Minor changes in the debian directory.
343       
344    - 1.20alpha27 :
345   
346        - Fixed many problems with translation files. In particular
347          the Brazilian Portuguese translation file was incorrectly
348          installed into the french "breton" locale directory.
349         
350        - Finished French translation. 
351         
352    - 1.20alpha26 :

364          to be a PyKota administrator when another command line
365          option is used.
366         
367        - pkhint doesn't use absolute path to search for helper commands

397          a PyKota administrator (a PyKota administrator is an user
398          allowed to read the pykotadmin.conf file).
399         
400        - Now any PyKota administrator can use repykota and warnpykota
401          with additionnal arguments, not only the root user.
402         
403        - Improved documentation a bit.
404

447         
448    - 1.20alpha15 :
449   
450        - LDAP pykotaAccountBalance objects were always created
451          attached to the pykotaUser objects. This is now
452          fixed and the value of balancebase in pykota.conf
453          is now correctly used.
454         
455    - 1.20alpha14 :
456

467        - Hardware accounter now accepts the special
468          'snmp' value, meaning ALL is done from main code
469          without launching any subprocess.
470          You need the http://pysnmp.sf.net Python module
471          for this to work (tested with v3.4.2)
472         
473        - Increased delay between two loops iterations 
474          to 2 seconds in waitprinter.sh to diminish
475          CPU load.
476         
477    - 1.20alpha12 :

479        - waitprinter.sh rewritten from scratch to wait
480          for printer status stabilization.
481       
482    - 1.20alpha11 :
483   
484        - Generic data dumper 'dumpykota' introduced.
485          Works only with PostgreSQL backend for now.

510        - Small fixes for LPRng.
511       
512        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
513          hostname or IP address. Set to 'localhost' when not
514          meaningful.
515         
516        - Fixed issue with how mod_auth_ldap Apache modules
517          fills the REMOTE_USER environment variable.
518         
519        - Fixed a bug in LDAP user deletion code.
520       
521    - 1.20alpha5 :
522     
523        - Introduces the new configuration directive 'onaccountererror'
524          to specify what must be done whenever the software or
525          hardware accounter fails. Allowed values are 'continue' and
526          'stop' (default).
527         
528        - Minor fix in software accounter for a recently introduced
529          problem.
530         
531    - 1.20alpha4 :
532   
533        - Added support for more ghostscript devices in ESC/P2
534          analyzer : stcolor, st800, escp, escpc are now supported.
535         
536    - 1.20alpha3 :
537       
538        - Small improvement in PostScript parser to avoid being
539          fooled by a change in number of copies :
540          The user can't ask for 200 copies of page 1 and 1 copy
541          of page 2 to fool PyKota anymore :
542          this would have been accounted for as 1 copy only, but
543          now the maximum value seen is used.
544         
545        - Relax checks for PCL5 header to accomodate some strange
546          printer drivers.
547         
548        - Now hardware accounting method works like software
549          accounting method wrt the subprocess' output.
550         
551        - Hardware and Software accounting stop the print queue 
552          when the accounting subprocess didn't work. This will
553          be configurable in the near future.
554         
555    - 1.20alpha2 :
556   
557        - Now software accounting method reads accounter's
558          answer until a line with a single integer is
559          obtained or until all of its output has been read.
560          This should fix the problem some people have
561          when strange locale related messages are sent
562          when running subprocesses (Solaris only ?).
563         
564        - First version of ESC/P2 analyzer. Seems to work
565          ok at least with 'epson', 'epsonc', 'eps9mid'
566          and 'esp9high' ghostscript devices. Needs more
567          work to correctly analyze other devices.
568       
569    - 1.20alpha1 :
570   
571        - Fixed problem with number of copies in PCLXL parser.
572       
573        - Fixed problem with number of copies in PCL5 parser,
574          when number of copies was set outside of and before first
575          page.
576       
577        - Added workaround for number of copies directly set in
578          PostScript code.
579         
580        - Added german translation.
581       
582        - Fixed problem on first print for user group quota when
583          "enforcement: strict" is used.
584       
585        - Fixed interpolation problem in french translation.
586       
587    - 1.19 :
588   
589        - Updated existing translations.   
590       
591        - Added final Thai and Greek translations.
592       
593        - Minor last minute bug fixes.
594       
595    - 1.19beta :
596   
597        - LPRng support for both software and hardware accounting seems
598          to be OK.
599         
600        - Translation files fixed because of fuzzy matching problem. 
601       
602        - Fixed path to Swedish translation: 'sv' instead of 'se'.
603       
604        - Added first draft of Thai translation.
605       
606        - Fixed some minor bugs with Pychecker.
607       
608    - 1.19alpha35 :
609   
610        - Generic PDL analyzer now supports Binary PostScript documents
611          in addition to DSC compliant ones.
612       
613    - 1.19alpha34 :
614   
615        - LPRng support : software accounting seems to work fine,
616          but hardware accounting doesn't work yet.
617   
618    - 1.19alpha33 :
619   
620        - pykosd now accepts command line arguments. Enjoy !
621          NB : due to a bug in xosd, you need xosd version 2.2.8
622          or higher if you don't use the default C locale.
623         
624    - 1.19alpha32 :
625   
626        - Early (not working) version of the LPRng support rewrite.
627       
628        - Saner default configuration file.
629       
630    - 1.19alpha31 :
631   
632        - Fixed a double Python2.1 incompatibility with newer versions,
633          which prevented the PCL5 and the PCLXL parsers to work with
634          this older version of Python.
635         
636    - 1.19alpha30 :
637   
638        - Introduction of preliminary version of the pykosd command
639       
640        - Usernames, Groupnames and Printernames can now contain
641          ANY character, expected '/' and '@'.
642       
643        - Integrated most of the Debian work from Sergio
644          Gonz�z Gonz�z
645         
646    - 1.19alpha29 :
647   
648        - PCLXL parser should now correctly handle number of
649          copies set for each page.
650         
651        - Added testsuite for generic PDL analyzer.
652       
653        - Typo fixed in PCLXL parser.
654       
655        - Correctly dispatches error messages depending on the
656          situation : tools which can be run interactively will
657          ALWAYS output their logs to stderr, excepted for
658          their DEBUG messages, for which the "logger:"
659          directive as set in pykota.conf will be honored.
660          Tools which can't be run interactively will ALWAYS
661          honor the "logger:" directive as set in pykota.conf
662         
663    - 1.19alpha28 :
664   
665        - The description field for printers can now be set,
666          and is displayed in reports.
667         
668        - Fixed a small problem in SQL backend code.
669         
670        - Improved pkhint
671       
672        - First working PCL6 (aka PCLXL) parser !
673          Doesn't handle copies yet.
674       
675    - 1.19alpha27 :
676   
677        - Additionnal 10% speed increase in PCL5 parser for GhostScript
678          generated files (untested yet with other PCL files).
679         
680        - Reintroduced the use of mmap in PCL5 parser : this speedups
681          PCL5 parsing by almost 4 times.
682          This 4x with the 3x below give us in fact a twelvefold increase
683          in performance for PCL5 parsing !
684         
685        - The Python accelerator Psyco is now used if available
686          in the generic PDL parser : it speedups PCL5 parsing by
687          almost three times automagically.
688         
689    - 1.19alpha26 :
690   
691        - Fixed PCL5 parser according to the sources of rastertohp.
692       
693        - Fixed number of copies handling in PCL5 parser : the number
694          of copies could vary from page to page.
695         
696        - Added more debug information to PCLXL parser. 
697       
698    - 1.19alpha25 :
699   
700        - Added new "description" field to printers in both
701          PostgreSQL and LDAP. No code to handle this yet.
702         
703        - Reversed the fix for power save mode in printers : 
704          no paper or tray open would have caused people to
705          be undercharged.
706         
707        - Preliminary version of MySQL initialization script.
708         
709    - 1.19alpha24 :
710   
711        - Native PDF parsing code now works perfectly with
712          Python 2.1 and above, and is way faster than before.
713          GhostScript is not used anymore to convert PDF to PS,
714          because PDF is parsed directly.
715         
716    - 1.19alpha23 :
717   
718        - Fixed waitprinter.sh wrt PowerSave mode and some
719          printers. Thanks to Ryan Suarez.
720       
721        - Smart PDL analyzer now recognizes PDF too : two
722          PDF parsing methods are used : a native one which
723          is very fast but requires Python 2.3 or above, and
724          a slower one which uses Ghostscript. PyKota detects
725          automatically which method to use depending on your
726          version of Python.
727       
728        - All tracebacks now include PyKota's version number.
729         
730    - 1.19alpha22 :
731   
732        - Ensures that the file pointer for job's data is
733          reset to the start of the job's datas after the
734          job's size pre-computation phase.
735         
736        - Improved PostScript detection code for bad drivers
737          which don't correctly switch languages between PJL
738          and PS.
739       
740        - Even better debugging code.
741       
742    - 1.19alpha21 :
743   
744        - Additionnal check.
745       
746    - 1.19alpha20 :
747   
748        - More complete logging messages wrt accounters.
749       
750        - Now catches early failures occuring when the configuration
751          files are parsed.
752       
753    - 1.19alpha19 :
754   
755        - Fixed over-verbose exits when displaying help
756          or version.
757         
758        - Extended some PATH in the shell scripts 
759       
760        - Deleting an user now also deletes his payments history.
761       
762        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
763          cause problems.
764
765    - 1.19alpha18 :
766   
767        - History of payments is now stored in the database, and
768          updated each time an user's balance is modified with
769          edpykota --balance. This history represents each time
770          the user was given some positive or negative credit,
771          but doesn't reflect price paid for jobs, which appear
772          in the jobs history instead.
773         
774        - Jobs history web reports now include the job's size in
775          bytes. Also columns were reordered to render the report
776          more easily readable.
777         
778    - 1.19alpha17 :
779   
780        - Mysterious bug (program exited unexpectedly without leaving
781          any log message) which occured once in a while when
782          cancelling jobs should be fixed now.
783         
784        - New 'crashrecipient' directive. Disabled by 
785          default. See sample configuration file to see how
786          to activate it. It is suggested that you activate it.
787         
788        - New PYKOTAJOBSIZEBYTES environment variable exported, 
789          which contains the job's size in bytes. Empty jobs
790          are now denied. This value is now stored in the job
791          history (but not yet displayed from the web interface)
792         
793        - Preliminary work on payments storage : the PostgreSQL 
794          and LDAP schemas should be OK now, but no code is written
795          yet to support this functionnality.
796         
797    - 1.19alpha16 :
798   
799        - the newuser and newgroup LDAP specific directives now accept
800          a second parameter to attach(), "fail" or "warn". If no entry
801          is found to attach PyKota attributes to, and "fail" was used,
802          then action is aborted and program exits in error. If "warn"
803          is used, a new entry is created but a warning message is logged.
804         
805        - The job's originating hostname is now stored in the database,
806          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
807       
808    - 1.19alpha15 :
809   
810        - The old pykota filter is now removed. This means that
811          currently PyKota doesn't support LPRng anymore, but
812          LPRng support will be re-added, improved, in the near future.
813         
814    - 1.19alpha14 :
815   
816        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
817          are now exported as environment variables.
818         
819        - Heavy CPU usage is now completely fixed it seems, by
820          introducing some 0.01 second sleeping when nothing to do.
821         
822        - Pre-computation of the job's size is now only
823          done when enforcement is "STRICT", this saves
824          CPU for people who don't want to use this new
825          feature.
826         
827        - New 'enforcement' directive which accepts either
828          STRICT or LAXIST. See sample configuration file
829          for details.
830         
831    - 1.19alpha13 :
832   
833        - Get back to an old version of the polling loop which
834          worked fine, but non-optimally. Will be optimized
835          as time permits.
836         
837    - 1.19alpha12 :
838   
839        - Job's size is now precomputed unconditionnally using
840          the generic PDL analyzer.
841          NB : This value is not yet used to pre-allow/deny the
842          job.
843       
844    - 1.19alpha11 :
845   
846        - The pykota filter is now completely deprecated and
847          can't be used anymore. LPRng users MUST download
848          an older version of PyKota. CUPS users MUST use
849          cupspykota. Better support for LPRng will come
850          in the near future.
851         
852    - 1.19alpha10 :
853   
854        - pykotme now uses generic PDL Analyzer directly instead
855          of spawning a new process.
856         
857        - Improvements to generic PDL Analyzer.
858       
859        - 25% Speedup in PCL parser. Getting more of the Python version
860          will probably be difficult, since the completely table driven
861          parser I wrote is slower than the original algorithm. Then,
862          the original algorithm is still used for now.
863          Probable that more speed could be achieved using mmap, at the
864          expense of severe memory consumption.
865       
866        - configuration simplifications : the "accounter" directive's
867          'hardware' arguments now accepts what was in the "requester"
868          directive as it's content. The "requester" directive is not
869          supported anymore. See sample configuration file for details.
870       
871    - 1.19alpha9 :
872       
873        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
874       
875        - pykotaOptions LDAP attribute now accepts non-ascii characters
876          too.
877         
878        - First try at cupspykota main loop rewrite
879       
880    - 1.19alpha8 :
881   
882        - 'querying' accounting method is now called 'hardware'
883       
884        - 'external' accounting method is now called 'software'
885       
886        - 'stupid' accounting method doesn't exist anymore
887       
888        - 'snmp' requester doesn't exist anymore
889       
890        - code simplifications in external requester
891       
892    - 1.19alpha7 :
893     
894        - Database schema change (both LDAP and PostgreSQL) to
895          allow storage of the job-originating-hostname attribute.
896          An SQL upgrade script is present. The code is not yet
897          capable of setting/retrieving this attribute. Support
898          for this functionnality will be added in the future.
899         
900    - 1.19alpha6 :
901   
902        - problems connecting to SMTP servers are now catched.
903       
904        - pykotme now uses pkpgcounter to compute the size of the
905          job. This modification adds PCL5 and soon PCLXL (PCL6)
906          support. You can now get quotes for PCL in addition to
907          PostScript.
908         
909        - pkpgcounter now includes first try at PCLXL parser. 
910          It is currently disabled until it's finished.
911         
912    - 1.19alpha5 :
913   
914        - cupspykota polling loop fix for MacOSX (at least)
915       
916        - logging subsystem now logs PID too, to ease diagnosing
917          problems under heavy load.
918         
919        - pkpgcounter enhancements.
920       
921        - pkprinters --skipexisting now tells pkprinters to not
922          modify existing printers when --add is used.
923          pkprinters logs a warning message whenever --add is
924          used and a printer already exists.
925         
926        - LDAP schema now allows accented chars in pykotaFileName
927          and pykotaTitle attributes.
928       
929    - 1.19alpha4 :
930   
931        - a bad copy&paste prevented pkpgcounter to work at all, this
932          is now fixed.
933         
934        - improved PCL support in pkpgcounter, with the use of
935          HP PCL/PJL Reference Set
936          PCL5 Printer Language Technical Quick Reference Guide
937       
938        - pkpgcounter now uses mmap to speed things up : duration
939          is halved with the sample 87 pages PCL document I use for
940          testing.
941         
942    - 1.19alpha3 :
943   
944        - pkprinters now accepts the --list command line argument
945          to list informations about printers.
946         
947    - 1.19alpha2 :
948   
949        - pkpgcounter is now included as a smart external
950          accounter which can handle both PostScript and PCL.
951         
952    - 1.19alpha1 :
953   
954        - PYKOTALIMITBY environment variable is now exported too.
955       
956        - Inclusion of Michele Baldessari's work on autotools.
957       
958    - 1.18 :
959   
960        - Improved documentation
961       
962    - 1.18beta2 :
963     
964        - Fix for raw jobs with cupspykota
965       
966    - 1.18beta :
967   
968        - Small fix for new waitprinter.sh script
969       
970        - Better tracebacks on error conditions
971       
972        - Improved translations
973       
974        - Improved documentation
975       
976    - 1.18alpha15 :
977
978        - waitprinter.sh replaced by a new and possibly faster
979          and more powerful one.
980   
981        - Names can now begin with a digit.
982       
983        - Stability improvement for quotas set on printers groups.
984       
985    - 1.18alpha14 :
986   
987        - Catches more (all ?) problems with SMTP servers instead
988          of breaking.
989         
990        - Italian translation added.
991       
992    - 1.18alpha13 :
993   
994        - Pre and Post hooks are now available in the pykota
995          filter as well.
996         
997        - The pykota filter doesn't check last user's quota
998          anymore when delayed hardware accounting is used :
999          this will be done anyway the next time the last
1000          user will print again. This saves some database

1051        - Preliminary work on future low-level LDAP caching to speed
1052          up modifications (at least).
1053         
1054    - 1.18alpha4 :
1055   
1056        - Applied some of the modifications suggested by
1057          Peter Hawkins, for better Debian integration.
1058          Most notably cupspykota, pykota, and the shell
1059          scripts are now installed into /usr/share/pykota
1060          instead of into /usr/bin
1061          BEWARE : double check that your symbolic link
1062          to cupspykota is correct, and that your pykota.conf
1063          file use correct path for the shell scripts like
1064          waitprinter.sh and al.
1065         
1066        - pkhint command added, to help in configuring correct

1104          though.
1105       
1106        - Portuguese Portuguese translation replaces Brazilian
1107          Portuguese Translation. Brazilian portuguese
1108          translation is still available under the 'br' locale.
1109       
1110    - 1.16beta3 :

1119          printing in CUPS backend.
1120         
1121        - Big fix wrt printing policies for unknown users. 
1122       
1123    - 1.16beta1 :
1124   
1125        - Manpages upgraded.

1130       
1131          SUM((NbPages * PricePerPage) + PricePerJob)
1132         
1133          For current printer and all the printers groups it is
1134          a member of, if any.
1135         
1136          This may be difficult to grasp, but offers unprecedented
1137          flexibility.

1177       
1178    - 1.16alpha18 :
1179   
1180        - Initial code for printer groups support. Printer groups have
1181          to be added with external tools like psql or gq for example.
1182          Printer groups seems to work fine with users. Untested with user
1183          groups for now.
1184
1185        - Several minor visual problems fixed in reports.
1186       
1187        - Fixed a bug in LDAP date handling.
1188

1193          for details.
1194       
1195        - Several environment variables are now exported when executing
1196          external commands (accounters, requesters, mailers) :
1197           
1198            PYKOTAUSERNAME => user who is printing
1199            PYKOTAPRINTERNAME => printer on which the job is being sent
1200            PYKOTATITLE => Job's title
1201            PYKOTAFILENAME => Job's filename
1202            PYKOTACOPIES => number of copies asked
1203            PYKOTAOPTIONS => print command options (-o with CUPS)
1204         
1205    - 1.16alpha17 :
1206   
1207        - Added portugues translation.
1208       
1209        - Major code refactoring in accounters.
1210

1212   
1213        - Code refactoring, and addition of a real HTML reporter, to
1214          have nice looking and useful web based reports (in the future).
1215       
1216        - Added utolower configuration option to convert all usernames
1217          to lowercase during printing.

1224    - 1.16alpha14 :
1225   
1226        - Now printing on a printer not defined in the Quota Storage,
1227          results in the job being cancelled or stopped, depending
1228          on the printing system.
1229         
1230    - 1.16alpha13 :
1231   
1232        - Small bugfix wrt Python v2.1
1233       
1234        - If username is an empty string, user root is assumed.
1235       
1236        - 'postgresql' is not recognized anymore as a storage backend,
1237          you have to use 'pgstorage' instead. 'postgresql' used to
1238          be supported for compatibility with very old PyKota versions,
1239          this is not the case anymore.
1240         
1241    - 1.16alpha12 :
1242   
1243        - Job price added to job history, to keep accounting correct
1244          if a printer price per page or per job is modified and the
1245          history is not reset : the history would have given a false
1246          amount of money charged before the printer's prices were
1247          modified, this addition solves the problem.
1248         
1249    - 1.16alpha11 :
1250   
1251        - Some preliminary modifications to the database structure for
1252          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1253          database is now provided. LDAP attributes now support
1254          eq, pres and sub indexes.
1255         
1256        - Job history now contains additional informations : 
1257          number of copies, filename, title and print options.
1258         
1259    - 1.16alpha10 :
1260       
1261        - Some modifications done to external policy handling.
1262          See sample configuration file for details.
1263   
1264        - Spanish translation added.
1265       
1266    - 1.16alpha9 :
1267   
1268        - mailto can be set to external(...) to warn users above
1269          quota with any command of your choice (e.g. linpopup).
1270          Several parameters are available, see sample configuration
1271          file for details.
1272         
1273    - 1.16alpha8 :
1274   
1275        - Now cupspykota transmits SIGTERMS to the original 
1276          backend when the user deletes a job being processed.
1277         
1278        - The documentation is now licensed under the terms of the
1279          GNU GPL too.
1280         
1281    - 1.16alpha7 :

1283        - The CUPS backend is now fully functionnal (it seems).
1284       
1285        - From now on, the use of the pykota filter with CUPS
1286          is deprecated. The pykota filter still has to be
1287          used with LPRng though.
1288       
1289    - 1.16alpha6 :
1290   
1291        - Bug fixed : when edpykota was used to add a printer
1292          with no user or group name, a bad user/group name "*" was
1293          added to the database.
1294         
1295    - 1.16alpha5 :
1296   
1297        - New CUPS backend supports device enumeration !
1298          This means that NO manual CUPS configuration has to
1299          be done. All can now be done from CUPS web interface.
1300       
1301    - 1.16alpha4 :
1302   
1303        - New CUPS backend added.
1304       
1305    - 1.16alpha3 :
1306       
1307        - Minimal FAQ document added.

1316       
1317        - More complete error messages in case of LDAP operation failure.
1318       
1319    - 1.15 :
1320

1325        - Command line tools now accept multiple printer
1326          names or wildcards, separated with commas.
1327         
1328    - 1.15alpha9 :
1329   
1330        - External policy can be used to auto-add unknown users
1331          and any other interesting things you may want to do.
1332          WARNING : You can't auto-add printers for now.
1333          They have to be created manually before.
1334          Look at sample configuration file for examples.
1335         
1336    - 1.15alpha8 :
1337   
1338        - Job history can be disabled if needed.
1339          This feature may be useful for people who use the LDAP
1340          backend and don't want their LDAP tree to grow out of
1341          control.
1342       
1343    - 1.15alpha7 :
1344   
1345        - More work done on caching wrt groups.

1354
1355    - 1.15alpha4 :
1356   
1357        - Problem with Python 2.3 fixed. Needs some definitive
1358          modification.
1359         
1360    - 1.15alpha3 :
1361   
1362        - CGI script now tries to restrict view when the
1363          REMOTE_USER environment variable is set. This allows
1364          people to protect its use with .htaccess files.
1365          When unprotected, or if REMOTE_USER is 'root', then
1366          unrestricted access is granted.
1367          NB : REMOTE_USER is automatically set by the web server
1368          (e.g. Apache) when a page with restricted access is viewed.
1369         
1370    - 1.15alpha2 :
1371   
1372        - Better detection of LPRng.
1373       
1374        - Outputs a warning if printing system is unknown.
1375       
1376    - 1.15alpha1 :
1377   
1378        - Bug fix in SQL code.
1379       
1380    - 1.14 :
1381   
1382        - The PostgreSQL database connection is now always closed before
1383          exit. The LDAP database connection too, but it didn't suffer
1384          from the problem anyway, AFAICT.
1385       
1386    - 1.14beta2 :
1387   
1388        - An LDAP-specific configuration field was introduced, usermail.
1389          Use it to specify which LDAP attribute contains a valid email
1390          address for the user. See sample configuration file for
1391          details.
1392       
1393    - 1.14beta :
1394   
1395        - Two new LDAP-specific configuration fields were introduced,
1396          newuser and newgroup. Use them to specify if you want to add
1397          quota information to existing entries or elsewhere.
1398          See sample configuration file for details.
1399         
1400    - 1.14alpha9 :
1401   
1402        - Documentation improved.
1403       
1404        - pykotme now also prints the user's account balance value
1405          if the user is registered in the Quota Storage and his
1406          limiting factor is "balance".
1407         
1408    - 1.14alpha8 :
1409   
1410        - bin/waitprinter.sh is now included to wait for
1411          SNMP enabled printers to be idle again before
1412          asking for their internal page counter.
1413          See sample configuration file for details.
1414         
1415    - 1.14alpha7 :
1416   
1417        - edpykota now doesn't check if the user/group is above
1418          quota. The check is only done at print time. This
1419          prevents the sending of email messages when creating
1420          user quotas if quota is already reached at creation
1421          time.
1422         
1423    - 1.14alpha6 :
1424   
1425        - Configuration file split and moved to /etc/pykota/pykota.conf
1426          and /etc/pykota/pykotadmin.conf to prevent simple users to
1427          have Read/Write access to the Quota Database.
1428          Don't forget to :
1429         
1430                $ chmod 640 /etc/pykota/pykotadmin.conf
1431               
1432        - storageuser and storageuserpw configuration fields reintroduced
1433          for the same reason.
1434         
1435        - Code cleaning for future implementation of email addresses
1436          support in the PostgreSQL and LDAP backends.
1437         
1438    - 1.14alpha5 :
1439       
1440        - Big bug fixed when changing the prices for a printer
1441       
1442    - 1.14alpha4 :
1443   
1444        - When adding an user, the user itself and its account balance
1445          are now added in the same LDAP entry. Before they were added
1446          as two different LDAP entries.
1447         
1448    - 1.14alpha3 :
1449   
1450        - Email field added to PostgreSQL database. An upgrade script

1460          balance (below 1.0 by default, configurable) are sent
1461          a warning message.
1462         
1463        - All warning messages to users are now configurable. 
1464          NB : Warning messages to the administrator are not.
1465       
1466    - 1.13 :
1467   
1468        - Some small fixes wrt group handling.
1469       
1470        - The whole module code was passed through PyChecker and
1471          several small code inconsistencies were fixed,
1472          as well as a bug in the groups code.
1473         
1474    - 1.13alpha1 :
1475   
1476        - Bug fix wrt LDAP.
1477       
1478    - 1.12 :
1479   
1480        - More complete test added in edpykota.
1481       
1482    - 1.12alpha2 :
1483   
1484        - The previous bug fix was incomplete. This is corrected.
1485

1493          printing quotes for users.
1494         
1495    - 1.10 :
1496   
1497        - Bug fixed wrt quota reports when print limiting is by
1498          account balance.

1520       
1521        - LDAP backend works !
1522       
1523        - repykota and warnpykota allow the root user to pass
1524          users or groups names on the command line. Users
1525          and groups names may contain wildcards.
1526         
1527        - repykota and warnpykota only reports or warns the
1528          current user when launched by non-root users.
1529         
1530        - Minor bug fixes. 
1531   
1532    - 1.09alpha1 :
1533   
1534        - More work on LDAP storage backend. Many options
1535          were added to /etc/pykota.conf to give some
1536          hints to the LDAP storage backend.
1537         
1538        - Severe database access optimizations were done by
1539          rewriting most of the Quota Storage backends drivers.
1540     
1541    - 1.08 :
1542   
1543        - Major bug fix wrt LPRng support for remote jobs.
1544       
1545        - Major bug fix wrt increase/decrease account balances.
1546       
1547    - 1.08alpha8 :
1548   
1549        - Code refactoring.
1550       
1551        - A single user/password pair is used to connect
1552          to the database backend. The storageuser configuration
1553          field, and its associated passwords storageuserpw, are
1554          not used anymore.
1555         
1556        - You can now set PyKota in debug mode, see sample configuration 
1557          file for details.
1558          WARNING : only Quota Storage backend queries are logged in
1559          debug mode, for now.
1560       
1561    - 1.08alpha7 :
1562   
1563        - Very latest LDAP schema.
1564       
1565        - Code enhancement wrt easy pluggability of PyKota attributes
1566          and object classes into an existing LDAP directory.
1567       
1568    - 1.08alpha6 :
1569   
1570        - Minor bug corrections
1571       
1572        - More work on LDAP : new schema
1573       
1574    - 1.08alpha5 :
1575   
1576        - More good work on LDAP storage.
1577          repykota now works reasonably well with the sample LDAP directory.
1578       
1579    - 1.08alpha4 :
1580   
1581        - LDAP schema included.
1582          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
1583          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1584          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1585          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1586          MAILING LIST.
1587         
1588    - 1.08alpha3 :
1589   
1590        - External accounting methods were partly rewritten :
1591         
1592          - No more "broken pipe" should happen.
1593         
1594          - They now take care of the number of copies
1595            This may be unneeded though, if the postscript
1596            file already does this, because this would
1597            overcharge users (number of copies counted
1598            two times). NEEDS MORE TESTING.
1599           
1600          - The sample configuration file now contains 
1601            an external accounting method example which should
1602            work with all DSC compliant Postscript files.
1603           
1604        - Some small bugs were fixed.   
1605       
1606    - 1.08alpha2 :
1607   
1608        - Now works with net-snmp v5.0 and above.
1609          It already worked, but the sample configuration
1610          file didn't contain appropriate values...
1611       
1612    - 1.07 : Release of the Shame !
1613   
1614        - The external accounting methods driver was left out of
1615          the CVS tree. Nobody could use it since it wasn't included !
1616         
1617    - 1.06 :
1618   
1619        - Severe bug fixed : if you had a printer in
1620          power saving state which couldn't answer immediately,
1621          a bug was triggered.
1622          It was caused by a bad copy/paste which
1623          forgot to import a Python module at run time.
1624         
1625    - 1.05 :
1626   
1627        - External accounters are finally available !
1628          This means that you can plug any page accounting
1629          method you like by setting the appropriate
1630          'accounter' field in /etc/pykota.conf
1631          See the sample conf/pykota.conf.sample to
1632          learn how to do.
1633         
1634          NB : Both 'external' and 'stupid' accounting methods
1635               account a job size just before *this* job is
1636               sent to the printer.
1637               The original 'querying' method accounts a job
1638               size just before *the next* job is sent to
1639               the printer.
1640       
1641    - 1.05alpha3 :
1642   
1643        - A 'stupid' and unreliable accounting method was
1644          implemented to serve as an example on how to
1645          do this sort of things. This method only counts
1646          the 'showpage' statements in the input data.
1647          See sample configuration file for details.
1648          Pluggable accounting methods work, but I advise
1649          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1650          It is not reliable enough to be used.
1651          Use the 'querying' accounting method instead.
1652         
1653    - 1.05alpha2 :
1654   
1655        - Pluggable accounting methods.
1656       
1657        - Better error handling.
1658       
1659    - 1.05alpha1 :
1660   
1661        - SECURITY file added to help improve PyKota's security.
1662       
1663        - Extracting the printer's internal page counter is now
1664          tried several times, waiting several seconds between
1665          two tries. This lets the time to warm up for some printers
1666          which don't answer when they are sleeping (my Apple
1667          LaserWriter 16/600 PS is in this case, maybe others too)
1668         
1669        - Small display bug fixed in repykota
1670         
1671    - 1.04 :
1672   
1673        - Default print policy for users/groups unknown from
1674          the print quota system is now DENY instead of ALLOW,
1675          since ALLOW can generate inaccurate results
1676          (incorrect job sizes charged to the wrong persons)
1677         
1678        - LPRng support works !
1679       
1680        - A bug was introduced some time ago wrt printers' default
1681          policy for unknown users. It is now corrected.
1682       
1683        - repykota now displays prices per job and per page for each
1684          printer, if they are defined.
1685         
1686        - Minor display bug fixed in repykota.
1687       
1688        - Problem when running repykota with an empty database was fixed.
1689       
1690    - 1.03 :
1691   
1692        - Upgrade script included for earlier versions.
1693          Please look inside the initscripts subdirectory.
1694          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1695         
1696        - repykota now reports account balances too.
1697       
1698        - PyKota now has a nice logo, see the logos
1699          subdirectory.
1700       
1701        - Manual pages were finally updated.
1702       
1703        - Group quotas seem to work now !
1704       
1705        - The new database schema allows to keep an history of all
1706          jobs as well as charge users per page and/or per job,
1707          and track users' account balance.
1708         
1709        - edpykota now accepts much more command line options to 
1710          use the new functionnalities. See edpykota --help for
1711          details.
1712         
1713        - The installation script now allows to install the sample
1714          configuration file during first installation.
1715         
1716        - More group quota code works, but still not finished. 
1717       
1718        - The CGI script displays a link to PyKota's website.
1719       
1720        - The job history is now kept, this will allow per-period
1721          reports in the future.
1722         
1723        - After having modified the quota for an user with edpykota,
1724          a quota check is done to eventually warn the user/admin about
1725          a quota which is too low to print.
1726         
1727        - A workaround is provided for HP Printers : their internal
1728          page counter is only saved to NVRAM in a 10 increment, so
1729          if you switch them off and then on, the reported page counter
1730          may be lower than the real number of pages printed.
1731          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1732          We unconditionnally set the last job's page count to
1733          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1734          in this case.
1735          For a more accurate accounting, never switch your HP printers
1736          off.
1737         
1738        - A fix is provided for printers which only have a volatile 
1739          page counter (reset to 0 every time you switch the printer on)
1740          This should allow PyKota to work reasonably fine with HP Laserjet
1741          4L/5L/6L, not perfect, but better than nothing.
1742          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1743          For a more accurate accounting, never switch your HP printers
1744          off. This is untested, please report any problem.
1745         
1746        - A bug was fixed when edpykota --add was used with users who already
1747          had a quota on the specified printer.
1748         
1749        - A small display bug in repykota was introduced in preliminary
1750          1.03 versions, and fixed later on.
1751         
1752        - Some minor bugs which happened in rare situations were fixed.
1753       
1754        - Support for AppleTalk printers was added, see sample configuration
1755          file for details.
1756         
1757        - Users and group printing can now be controlled (limited) either by 
1758          print quota or by account balance.
1759       
1760    - 1.02 :
1761   
1762        - The installation script now checks for software availability
1763          and in case a software is missing asks the user if he
1764          wants to continue with the installation or abort it.
1765         
1766        - The configuration file pykota.conf is now expected to be
1767          found in /etc instead of in /etc/cups
1768          The installation script prompts the user to see if he
1769          wants to move an old configuration file to the new location
1770          if needed.
1771         
1772        - Improved documentation.
1773       
1774        - You can now set the tcp/ip port on which the Quota Storage
1775          Server is listening, see sample configuration file for details.
1776       
1777        - Better general error handling.
1778       
1779        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1780          included as well.
1781       
1782    - 1.01 :
1783   
1784        - The configuration file now accepts an option   
1785          to choose the recipient(s) of the email messages :
1786         
1787            - DevNull means no one will receive them.
1788            - User means only the user will receive them.
1789            - Admin means only the admin will receive them.
1790            - Both means the User and the Admin will receive them.
1791           
1792        - The configuration file now uses hard-coded default values
1793          when an option is not set. See sample configuration file
1794          for details.
1795         
1796        - Manual pages are included since 1.00, but I forgot to   
1797          add this information to this file.
1798         
1799        - Redistribution terms for the official package have 
1800          softened and are now fully GPL compatible :
1801          unrestricted modification is now allowed even for
1802          the version number.
1803         
1804    - 1.00 :
1805   
1806        - edpykota now accepts a --noquota option. This
1807          disable quota checking while still doing page
1808          accounting. This is really useful for people
1809          who don't want to limit their users but want
1810          to know how much pages they print.
1811         
1812        - Some untested scripts were added to retrieve
1813          the life time page counter of non-SNMP printers.
1814         
1815        - Every directory now has a specific README file. 
1816       
1817    - 0.99 :
1818   
1819        - Under some circumstances while the user wasn't allowed
1820          to print, he didn't receive any email message. It is
1821          now fixed.
1822         
1823        - When an user wasn't allowed to print, the quota for
1824          the previous user wasn't updated. This is now fixed.
1825         
1826    - 0.98 :
1827   
1828        - Correctly handle the case where the printer is switched off.
1829       
1830        - Small bug wrt syslog fixed.
1831       
1832    - 0.97 :
1833   
1834        - edpykota accepts wildcards on its command line for users/groups too
1835          if the --add option is not set, e.g. :
1836         
1837              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1838             
1839        - If no user name is passed at all, then a default wildcard of "*"
1840          which means apply the command on ALL users for this printer is used.
1841         
1842        - Small bug fixes.
1843       
1844    - 0.96 :
1845
1846        - Options requester, policy, admin, adminmail and gracedelay can now
1847          be set either globally or per printer. The printer option has
1848          priority if both are defined.
1849
1850        - More powerful configuration parser.
1851       
1852        - If all options are defined globally, there's no need to
1853          define a section for each printer in the configuration
1854          file anymore. Just define a [global] section and it's ok.
1855
1856    - 0.95 :
1857
1858        - External requesters for printers finally added.
1859
1860        - Full internationalization (english and french are supported)
1861 
1862        - More complete quota usage report
1863
1864        - CGI script to access to the quota usage report
1865
1866        - Several bugs fixed.
1867
1868
1869    - 0.9 :
1870
1871        - First public version
