36        - Early errors now produce meaningful error messages (finally !)
37       
38    - 1.22alpha5 :
39       
40        - SNMP and PJL improvements with regard to PowerSave / StandBy.

46        - Allows pkbanner to accept more info to display on its
47          command line.
48         
49    - 1.22alpha3 :
50   
51        - Fixes some case related problems with some LDAP backends.
52       
53        - Fixes some problem for printers which directly go from
54          "idle" to "warmup" and never to "printing" before
55          returning to "idle".
56         
57        - Some permissions settings may have prevented cupspykota
58          from parsing cupsd.conf, this is now fixed.
59         
60    - 1.22alpha2 :
61   
62        - Introduction of the web enabled print quote generator.
63       
64        - Fixed a potential race condition when several backend
65          wrappers were present in CUPS' backend directory.
66         
67        - Fixed dumpykota's output in CUPS' page_log format to better
68          match CUPS format.
69         
70    - 1.22alpha1 :
71   
72        - Import into Subversion.
73       
74    - 1.21 :
75   
76        - Improved documentation.
77       
78        - Improved dependencies checker.
79       
80        - Updated some translation files.
81       
82    - 1.21beta2 :
83   
84        - Fixed an LPRng specific bug.
85       
86        - Several improvements on stability issues with manually modified

92   
93        - Prepared translation files for next release.
94       
95    - 1.21alpha27 :
96   
97        - Allows software() (no arguments) to the software accounting
98          directive. This saves a lot of CPU since the job is not
99          parsed again : the precomputed size is used directly in this
100          case.
101         
102        - epykota's --prototype option now works fine with accounts
103          limited by balance.
104         
105    - 1.21alpha26 :
106   
107        - Fixed the handling of the 'maxdenybanners' directive.
108       
109        - Introduced the 'denyduplicates' directive.
110       
111        - Fixed some database related glitches.
112       
113    - 1.21alpha25 :
114   
115        - The job's size is now always precomputed, even when
116          'enforcement' is not set to 'strict'.
117         
118        - Introduction of the new 'trustjobsize' configuration directive
119          to workaround some problematic printers. See the sample
120          configuration file for details.
121         
122    - 1.21alpha24 :
123   
124        - Big database structure changes. An upgrade script
125          is now included for PostgreSQL. LDAP users may just
126          want to copy the new schema in place.
127         
128        - edpykota now recognizes the -o | --overcharge command line
129          option to set an overcharging or undercharging factor
130          on each print job's cost for a particular user.
131         
132        - repykota's output format has changed an is not limited to 
133          80 characters wide anymore. People who used to parse
134          repykota's output in their own tools are strongly advised
135          to parse dumpykota's output instead.
136         
137        - Introduction of the new 'maxdenybanners' configuration directive
138          to allow up to N (the directive's value) deny banners to be
139          printed even if the print account is forbidden to print.
140         
141        - Better detection of the number of copies in the PostScript parser.
142       
143    - 1.21alpha23 :
144   
145        - Traditional Chinese translation added.
146   
147        - Several fixes and performance improvements with the LDAP backend.
148       
149    - 1.21alpha22 :
150   
151        - edpykota's --delete command line option doesn't consider
152          '*' to be the default argument anymore :-)
153         
154    - 1.21alpha21 :
155   
156        - dumpykota.cgi can now be run as a normal user as opposed to
157          a PyKota administrator. No read access to pykotadmin.conf is
158          necessary anymore. This CGI scripts now honors the REMOTE_USER
159          environment variable just like printquota.cgi does, see
160          the file cgi-bin/README for details.
161          The command line tool dumpykota must still be run by a PyKota
162          administrator.
163         
164        - Fix exception's name error due to a change in recent versions
165          of PygreSQL.   
166         
167    - 1.21alpha20 :
168         
169        - Big bug fix wrt the datelimit field which was never reset.
170         
171    - 1.21alpha19 :
172   
173        - Introduction of the new dumpykota.cgi CGI script, which
174          allows third party tools like phpPrintAnalyzer to be
175          interfaced in real time with PyKota. To use it you
176          may have to change your web server's configuration,
177          please see pykota/cgi-bin/README
178         
179    - 1.21alpha18 :
180   
181        - Now dumpykota can dump the job history into CUPS' page_log
182          format (even when the printing system is LPRng). This allows
183          people to use tools like PrintAnalyzer or phpPrintAnalyzer
184          (two completely different beasts) with PyKota.
185         
186    - 1.21alpha17 :
187     
188        - Fixed field type's name in XML dumps.
189       
190        - Now drops priviledges to user 'pykota' when launched as root
191          (directly or as a CUPS backend), if such an user exists.
192         
193        - Fixed PCL3/4/5 parser for some drivers' output.
194       
195    - 1.21alpha16 :
196   
197        - fixed several recently introduced bugs in LDAP backend code,
198          thanks to Matt Hyclak.
199         
200    - 1.21alpha15 :
201     
202        - Normalized field names between LDAP and PostgreSQL backends
203          in dumpykota's output.
204         
205        - dumpykota filtering capabilities are now supported within
206          the LDAP backend too.
207         
208    - 1.21alpha14 :
209   
210        - dumpykota now supports extended filtering possibilities
211          with the PostgreSQL backend (LDAP support will come soon).
212         
213    - 1.21alpha13 :
214   
215        - Added a --debug command line option to pkpgcounter, so
216          that people may see what really happens, and what will
217          be available in the future :-)
218         
219    - 1.21alpha12 :
220   
221        - Fixed a bug with non standard pkbanner command lines.
222       
223        - Now logs as errors the differences between precomputed and
224          computed job sizes. **CUPS only for now**
225         
226    - 1.21alpha11 :
227   
228        - Now user and group print quota entries can be stored directly
229          below the user or group with the LDAP backend, using them
230          as branches. Thanks to Stefan Wold for the patch.
231          See the sample configuration file for details.
232         
233        - TLS is now supported with the LDAP backend. Thanks to Stefan
234          Wold for the patch.
235          See the sample configuration file for details.
236         
237        - edpkota now accepts the -U | --used value command line argument
238          to preset the page counters to an initial value. Thanks to
239          Wilson Roberto Afonso and Matt Hyclak for the patch.
240         
241    - 1.21alpha10 :
242   
243        - Now automatically reconnects up to three times if the LDAP server
244          returned an error, possibly due to a timeout.
245         
246    - 1.21alpha9 :
247   
248        - Now searches the configuration files in 'pykota' system user's
249          home directory. The 'pykota' system user and group have
250          to be created by the system administrator, and given
251          sufficient permissions to PyKota's configuration files.
252         
253    - 1.21alpha8 :

295         
296    - 1.21alpha1 :
297   
298        - added an IPP messages miniparser. Extraction of the client
299          hostname is now considered to be fiable, at least until
300          the CUPS developpers change something...
301       
302    - 1.20 :
303   
304        - Version number changed.
305

316          in the history.
317         
318        - Minor changes in the debian directory.
319       
320    - 1.20alpha27 :
321   
322        - Fixed many problems with translation files. In particular
323          the Brazilian Portuguese translation file was incorrectly
324          installed into the french "breton" locale directory.
325         
326        - Finished French translation. 
327         
328    - 1.20alpha26 :

338   
339        - pkprinters allows --list to normal users, but require user
340          to be a PyKota administrator when another command line
341          option is used.
342         
343        - pkhint doesn't use absolute path to search for helper commands

373          a PyKota administrator (a PyKota administrator is an user
374          allowed to read the pykotadmin.conf file).
375         
376        - Now any PyKota administrator can use repykota and warnpykota
377          with additionnal arguments, not only the root user.
378

423         
424    - 1.20alpha15 :
425   
426        - LDAP pykotaAccountBalance objects were always created
427          attached to the pykotaUser objects. This is now
428          fixed and the value of balancebase in pykota.conf
429          is now correctly used.
430         
431    - 1.20alpha14 :
432

444          'snmp' value, meaning ALL is done from main code
445          without launching any subprocess.
446          You need the http://pysnmp.sf.net Python module
447          for this to work (tested with v3.4.2)
448         
449        - Increased delay between two loops iterations 
450          to 2 seconds in waitprinter.sh to diminish
451          CPU load.
452         
453    - 1.20alpha12 :

511         
512    - 1.20alpha3 :
513       
514        - Small improvement in PostScript parser to avoid being
515          fooled by a change in number of copies :
516          The user can't ask for 200 copies of page 1 and 1 copy
517          of page 2 to fool PyKota anymore :
518          this would have been accounted for as 1 copy only, but
519          now the maximum value seen is used.
520         
521        - Relax checks for PCL5 header to accomodate some strange
522          printer drivers.
523         
524        - Now hardware accounting method works like software
525          accounting method wrt the subprocess' output.
526         
527        - Hardware and Software accounting stop the print queue 
528          when the accounting subprocess didn't work. This will
529          be configurable in the near future.
530         
531    - 1.20alpha2 :
532   
533        - Now software accounting method reads accounter's
534          answer until a line with a single integer is
535          obtained or until all of its output has been read.
536          This should fix the problem some people have
537          when strange locale related messages are sent
538          when running subprocesses (Solaris only ?).
539         
540        - First version of ESC/P2 analyzer. Seems to work
541          ok at least with 'epson', 'epsonc', 'eps9mid'
542          and 'esp9high' ghostscript devices. Needs more
543          work to correctly analyze other devices.
544       
545    - 1.20alpha1 :
546   
547        - Fixed problem with number of copies in PCLXL parser.
548       
549        - Fixed problem with number of copies in PCL5 parser,
550          when number of copies was set outside of and before first
551          page.
552       
553        - Added workaround for number of copies directly set in
554          PostScript code.
555         
556        - Added german translation.
557       
558        - Fixed problem on first print for user group quota when
559          "enforcement: strict" is used.
560       
561        - Fixed interpolation problem in french translation.
562       
563    - 1.19 :
564   
565        - Updated existing translations.   
566       
567        - Added final Thai and Greek translations.
568       
569        - Minor last minute bug fixes.
570       
571    - 1.19beta :
572   
573        - LPRng support for both software and hardware accounting seems
574          to be OK.
575         
576        - Translation files fixed because of fuzzy matching problem. 
577       
578        - Fixed path to Swedish translation: 'sv' instead of 'se'.
579       
580        - Added first draft of Thai translation.
581       
582        - Fixed some minor bugs with Pychecker.
583       
584    - 1.19alpha35 :
585   
586        - Generic PDL analyzer now supports Binary PostScript documents
587          in addition to DSC compliant ones.
588       
589    - 1.19alpha34 :
590   
591        - LPRng support : software accounting seems to work fine,
592          but hardware accounting doesn't work yet.
593   
594    - 1.19alpha33 :
595   
596        - pykosd now accepts command line arguments. Enjoy !
597          NB : due to a bug in xosd, you need xosd version 2.2.8
598          or higher if you don't use the default C locale.
599         
600    - 1.19alpha32 :
601   
602        - Early (not working) version of the LPRng support rewrite.
603       
604        - Saner default configuration file.
605       
606    - 1.19alpha31 :
607   
608        - Fixed a double Python2.1 incompatibility with newer versions,
609          which prevented the PCL5 and the PCLXL parsers to work with
610          this older version of Python.
611         
612    - 1.19alpha30 :
613   
614        - Introduction of preliminary version of the pykosd command
615       
616        - Usernames, Groupnames and Printernames can now contain
617          ANY character, expected '/' and '@'.
618       
619        - Integrated most of the Debian work from Sergio
620          Gonz�z Gonz�z
621         
622    - 1.19alpha29 :
623   
624        - PCLXL parser should now correctly handle number of
625          copies set for each page.
626         
627        - Added testsuite for generic PDL analyzer.
628       
629        - Typo fixed in PCLXL parser.
630       
631        - Correctly dispatches error messages depending on the
632          situation : tools which can be run interactively will
633          ALWAYS output their logs to stderr, excepted for
634          their DEBUG messages, for which the "logger:"
635          directive as set in pykota.conf will be honored.
636          Tools which can't be run interactively will ALWAYS
637          honor the "logger:" directive as set in pykota.conf
638         
639    - 1.19alpha28 :
640   
641        - The description field for printers can now be set,
642          and is displayed in reports.
643         
644        - Fixed a small problem in SQL backend code.
645         
646        - Improved pkhint
647       
648        - First working PCL6 (aka PCLXL) parser !
649          Doesn't handle copies yet.
650       
651    - 1.19alpha27 :
652   
653        - Additionnal 10% speed increase in PCL5 parser for GhostScript
654          generated files (untested yet with other PCL files).
655         
656        - Reintroduced the use of mmap in PCL5 parser : this speedups
657          PCL5 parsing by almost 4 times.
658          This 4x with the 3x below give us in fact a twelvefold increase
659          in performance for PCL5 parsing !
660         
661        - The Python accelerator Psyco is now used if available
662          in the generic PDL parser : it speedups PCL5 parsing by
663          almost three times automagically.
664         
665    - 1.19alpha26 :
666   
667        - Fixed PCL5 parser according to the sources of rastertohp.
668       
669        - Fixed number of copies handling in PCL5 parser : the number
670          of copies could vary from page to page.
671         
672        - Added more debug information to PCLXL parser. 
673       
674    - 1.19alpha25 :
675   
676        - Added new "description" field to printers in both
677          PostgreSQL and LDAP. No code to handle this yet.
678         
679        - Reversed the fix for power save mode in printers : 
680          no paper or tray open would have caused people to
681          be undercharged.
682         
683        - Preliminary version of MySQL initialization script.
684         
685    - 1.19alpha24 :
686   
687        - Native PDF parsing code now works perfectly with
688          Python 2.1 and above, and is way faster than before.
689          GhostScript is not used anymore to convert PDF to PS,
690          because PDF is parsed directly.
691         
692    - 1.19alpha23 :
693   
694        - Fixed waitprinter.sh wrt PowerSave mode and some
695          printers. Thanks to Ryan Suarez.
696       
697        - Smart PDL analyzer now recognizes PDF too : two
698          PDF parsing methods are used : a native one which
699          is very fast but requires Python 2.3 or above, and
700          a slower one which uses Ghostscript. PyKota detects
701          automatically which method to use depending on your
702          version of Python.
703       
704        - All tracebacks now include PyKota's version number.
705         
706    - 1.19alpha22 :
707   
708        - Ensures that the file pointer for job's data is
709          reset to the start of the job's datas after the
710          job's size pre-computation phase.
711         
712        - Improved PostScript detection code for bad drivers
713          which don't correctly switch languages between PJL
714          and PS.
715       
716        - Even better debugging code.
717       
718    - 1.19alpha21 :
719   
720        - Additionnal check.
721       
722    - 1.19alpha20 :
723   
724        - More complete logging messages wrt accounters.
725       
726        - Now catches early failures occuring when the configuration
727          files are parsed.
728       
729    - 1.19alpha19 :
730   
731        - Fixed over-verbose exits when displaying help
732          or version.
733         
734        - Extended some PATH in the shell scripts 
735       
736        - Deleting an user now also deletes his payments history.
737       
738        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
739          cause problems.
740
741    - 1.19alpha18 :
742   
743        - History of payments is now stored in the database, and
744          updated each time an user's balance is modified with
745          edpykota --balance. This history represents each time
746          the user was given some positive or negative credit,
747          but doesn't reflect price paid for jobs, which appear
748          in the jobs history instead.
749         
750        - Jobs history web reports now include the job's size in
751          bytes. Also columns were reordered to render the report
752          more easily readable.
753         
754    - 1.19alpha17 :
755   
756        - Mysterious bug (program exited unexpectedly without leaving
757          any log message) which occured once in a while when
758          cancelling jobs should be fixed now.
759         
760        - New 'crashrecipient' directive. Disabled by 
761          default. See sample configuration file to see how
762          to activate it. It is suggested that you activate it.
763         
764        - New PYKOTAJOBSIZEBYTES environment variable exported, 
765          which contains the job's size in bytes. Empty jobs
766          are now denied. This value is now stored in the job
767          history (but not yet displayed from the web interface)
768         
769        - Preliminary work on payments storage : the PostgreSQL 
770          and LDAP schemas should be OK now, but no code is written
771          yet to support this functionnality.
772         
773    - 1.19alpha16 :
774   
775        - the newuser and newgroup LDAP specific directives now accept
776          a second parameter to attach(), "fail" or "warn". If no entry
777          is found to attach PyKota attributes to, and "fail" was used,
778          then action is aborted and program exits in error. If "warn"
779          is used, a new entry is created but a warning message is logged.
780         
781        - The job's originating hostname is now stored in the database,
782          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
783       
784    - 1.19alpha15 :
785   
786        - The old pykota filter is now removed. This means that
787          currently PyKota doesn't support LPRng anymore, but
788          LPRng support will be re-added, improved, in the near future.
789         
790    - 1.19alpha14 :
791   
792        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
793          are now exported as environment variables.
794         
795        - Heavy CPU usage is now completely fixed it seems, by
796          introducing some 0.01 second sleeping when nothing to do.
797         
798        - Pre-computation of the job's size is now only
799          done when enforcement is "STRICT", this saves
800          CPU for people who don't want to use this new
801          feature.
802         
803        - New 'enforcement' directive which accepts either
804          STRICT or LAXIST. See sample configuration file
805          for details.
806         
807    - 1.19alpha13 :
808   
809        - Get back to an old version of the polling loop which
810          worked fine, but non-optimally. Will be optimized
811          as time permits.
812         
813    - 1.19alpha12 :
814   
815        - Job's size is now precomputed unconditionnally using
816          the generic PDL analyzer.
817          NB : This value is not yet used to pre-allow/deny the
818          job.
819       
820    - 1.19alpha11 :
821   
822        - The pykota filter is now completely deprecated and
823          can't be used anymore. LPRng users MUST download
824          an older version of PyKota. CUPS users MUST use
825          cupspykota. Better support for LPRng will come
826          in the near future.
827         
828    - 1.19alpha10 :
829   
830        - pykotme now uses generic PDL Analyzer directly instead
831          of spawning a new process.
832         
833        - Improvements to generic PDL Analyzer.
834       
835        - 25% Speedup in PCL parser. Getting more of the Python version
836          will probably be difficult, since the completely table driven
837          parser I wrote is slower than the original algorithm. Then,
838          the original algorithm is still used for now.
839          Probable that more speed could be achieved using mmap, at the
840          expense of severe memory consumption.
841       
842        - configuration simplifications : the "accounter" directive's
843          'hardware' arguments now accepts what was in the "requester"
844          directive as it's content. The "requester" directive is not
845          supported anymore. See sample configuration file for details.
846       
847    - 1.19alpha9 :
848       
849        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
850       
851        - pykotaOptions LDAP attribute now accepts non-ascii characters
852          too.
853         
854        - First try at cupspykota main loop rewrite
855       
856    - 1.19alpha8 :
857   
858        - 'querying' accounting method is now called 'hardware'
859       
860        - 'external' accounting method is now called 'software'
861       
862        - 'stupid' accounting method doesn't exist anymore
863       
864        - 'snmp' requester doesn't exist anymore
865       
866        - code simplifications in external requester
867       
868    - 1.19alpha7 :
869     
870        - Database schema change (both LDAP and PostgreSQL) to
871          allow storage of the job-originating-hostname attribute.
872          An SQL upgrade script is present. The code is not yet
873          capable of setting/retrieving this attribute. Support
874          for this functionnality will be added in the future.
875         
876    - 1.19alpha6 :
877   
878        - problems connecting to SMTP servers are now catched.
879       
880        - pykotme now uses pkpgcounter to compute the size of the
881          job. This modification adds PCL5 and soon PCLXL (PCL6)
882          support. You can now get quotes for PCL in addition to
883          PostScript.
884         
885        - pkpgcounter now includes first try at PCLXL parser. 
886          It is currently disabled until it's finished.
887         
888    - 1.19alpha5 :
889   
890        - cupspykota polling loop fix for MacOSX (at least)
891       
892        - logging subsystem now logs PID too, to ease diagnosing
893          problems under heavy load.
894         
895        - pkpgcounter enhancements.
896       
897        - pkprinters --skipexisting now tells pkprinters to not
898          modify existing printers when --add is used.
899          pkprinters logs a warning message whenever --add is
900          used and a printer already exists.
901         
902        - LDAP schema now allows accented chars in pykotaFileName
903          and pykotaTitle attributes.
904       
905    - 1.19alpha4 :
906   
907        - a bad copy&paste prevented pkpgcounter to work at all, this
908          is now fixed.
909         
910        - improved PCL support in pkpgcounter, with the use of
911          HP PCL/PJL Reference Set
912          PCL5 Printer Language Technical Quick Reference Guide
913       
914        - pkpgcounter now uses mmap to speed things up : duration
915          is halved with the sample 87 pages PCL document I use for
916          testing.
917         
918    - 1.19alpha3 :
919   
920        - pkprinters now accepts the --list command line argument
921          to list informations about printers.
922         
923    - 1.19alpha2 :
924   
925        - pkpgcounter is now included as a smart external
926          accounter which can handle both PostScript and PCL.
927         
928    - 1.19alpha1 :
929   
930        - PYKOTALIMITBY environment variable is now exported too.
931       
932        - Inclusion of Michele Baldessari's work on autotools.
933       
934    - 1.18 :
935   
936        - Improved documentation
937       
938    - 1.18beta2 :
939     
940        - Fix for raw jobs with cupspykota
941       
942    - 1.18beta :
943   
944        - Small fix for new waitprinter.sh script
945       
946        - Better tracebacks on error conditions
947       
948        - Improved translations
949       
950        - Improved documentation
951       
952    - 1.18alpha15 :
953
954        - waitprinter.sh replaced by a new and possibly faster
955          and more powerful one.
956   
957        - Names can now begin with a digit.
958       
959        - Stability improvement for quotas set on printers groups.
960       
961    - 1.18alpha14 :
962   
963        - Catches more (all ?) problems with SMTP servers instead
964          of breaking.
965         
966        - Italian translation added.
967       
968    - 1.18alpha13 :
969   
970        - Pre and Post hooks are now available in the pykota
971          filter as well.
972         
973        - The pykota filter doesn't check last user's quota
974          anymore when delayed hardware accounting is used :
975          this will be done anyway the next time the last
976          user will print again. This saves some database
977          queries which are unneeded.
978       
979    - 1.18alpha12 :
980   
981        - Pre and Post hooks to external commands with many
982          many environment variables available are useable
983          from the cupspykota backend.
984          See sample configuration file for details and help.
985         
986    - 1.18alpha11 :
987   
988        - Hopefully final fix wrt groups (users and printers)
989       
990    - 1.18alpha10 :
991   
992        - Fixed nested printer groups accounting.
993       
994        - Fixed user groups + printer groups problem.
995       
996    - 1.18alpha9 :
997   
998        - Fix for LDAP problem when job price was 0.
999       
1000        - Fix for empty user groups with LDAP.
1001       
1002        - Preliminary version of the snmpprinterstatus command added.
1003       
1004    - 1.18alpha8 :
1005

1028          up modifications (at least).
1029         
1030    - 1.18alpha4 :
1031   
1032        - Applied some of the modifications suggested by
1033          Peter Hawkins, for better Debian integration.
1034          Most notably cupspykota, pykota, and the shell
1035          scripts are now installed into /usr/share/pykota
1036          instead of into /usr/bin
1037          BEWARE : double check that your symbolic link
1038          to cupspykota is correct, and that your pykota.conf
1039          file use correct path for the shell scripts like
1040          waitprinter.sh and al.

1080          though.
1081       
1082        - Portuguese Portuguese translation replaces Brazilian
1083          Portuguese Translation. Brazilian portuguese
1084          translation is still available under the 'br' locale.
1085

1095          printing in CUPS backend.
1096         
1097        - Big fix wrt printing policies for unknown users.

1099    - 1.16beta1 :
1100   
1101        - Manpages upgraded.

1106       
1107          SUM((NbPages * PricePerPage) + PricePerJob)
1108         
1109          For current printer and all the printers groups it is
1110          a member of, if any.
1111         
1112          This may be difficult to grasp, but offers unprecedented
1113          flexibility.

1153       
1154    - 1.16alpha18 :
1155   
1156        - Initial code for printer groups support. Printer groups have
1157          to be added with external tools like psql or gq for example.
1158          Printer groups seems to work fine with users. Untested with user
1159          groups for now.
1160
1161        - Several minor visual problems fixed in reports.
1162       
1163        - Fixed a bug in LDAP date handling.

1169          for details.
1170       
1171        - Several environment variables are now exported when executing
1172          external commands (accounters, requesters, mailers) :
1173           
1174            PYKOTAUSERNAME => user who is printing
1175            PYKOTAPRINTERNAME => printer on which the job is being sent
1176            PYKOTATITLE => Job's title
1177            PYKOTAFILENAME => Job's filename
1178            PYKOTACOPIES => number of copies asked
1179            PYKOTAOPTIONS => print command options (-o with CUPS)
1180         
1181    - 1.16alpha17 :
1182   
1183        - Added portugues translation.
1184

1190          have nice looking and useful web based reports (in the future).
1191       
1192        - Added utolower configuration option to convert all usernames
1193          to lowercase during printing.

1200    - 1.16alpha14 :
1201   
1202        - Now printing on a printer not defined in the Quota Storage,
1203          results in the job being cancelled or stopped, depending
1204          on the printing system.
1205         
1206    - 1.16alpha13 :
1207   
1208        - Small bugfix wrt Python v2.1
1209       
1210        - If username is an empty string, user root is assumed.
1211       
1212        - 'postgresql' is not recognized anymore as a storage backend,
1213          you have to use 'pgstorage' instead. 'postgresql' used to
1214          be supported for compatibility with very old PyKota versions,
1215          this is not the case anymore.
1216         
1217    - 1.16alpha12 :
1218   
1219        - Job price added to job history, to keep accounting correct
1220          if a printer price per page or per job is modified and the
1221          history is not reset : the history would have given a false
1222          amount of money charged before the printer's prices were
1223          modified, this addition solves the problem.
1224         
1225    - 1.16alpha11 :
1226   
1227        - Some preliminary modifications to the database structure for
1228          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1229          database is now provided. LDAP attributes now support
1230          eq, pres and sub indexes.
1231         
1232        - Job history now contains additional informations : 
1233          number of copies, filename, title and print options.
1234         
1235    - 1.16alpha10 :
1236       
1237        - Some modifications done to external policy handling.
1238          See sample configuration file for details.
1239   
1240        - Spanish translation added.
1241       
1242    - 1.16alpha9 :
1243   
1244        - mailto can be set to external(...) to warn users above
1245          quota with any command of your choice (e.g. linpopup).
1246          Several parameters are available, see sample configuration
1247          file for details.
1248         
1249    - 1.16alpha8 :
1250   
1251        - Now cupspykota transmits SIGTERMS to the original 
1252          backend when the user deletes a job being processed.
1253         
1254        - The documentation is now licensed under the terms of the
1255          GNU GPL too.
1256         
1257    - 1.16alpha7 :

1259        - The CUPS backend is now fully functionnal (it seems).
1260       
1261        - From now on, the use of the pykota filter with CUPS
1262          is deprecated. The pykota filter still has to be
1263          used with LPRng though.
1264       
1265    - 1.16alpha6 :
1266   
1267        - Bug fixed : when edpykota was used to add a printer
1268          with no user or group name, a bad user/group name "*" was
1269          added to the database.
1270         
1271    - 1.16alpha5 :
1272   
1273        - New CUPS backend supports device enumeration !
1274          This means that NO manual CUPS configuration has to
1275          be done. All can now be done from CUPS web interface.
1276       
1277    - 1.16alpha4 :
1278   
1279        - New CUPS backend added.
1280       
1281    - 1.16alpha3 :

1301        - Command line tools now accept multiple printer
1302          names or wildcards, separated with commas.
1303         
1304    - 1.15alpha9 :
1305   
1306        - External policy can be used to auto-add unknown users
1307          and any other interesting things you may want to do.
1308          WARNING : You can't auto-add printers for now.
1309          They have to be created manually before.
1310          Look at sample configuration file for examples.
1311         
1312    - 1.15alpha8 :
1313   
1314        - Job history can be disabled if needed.
1315          This feature may be useful for people who use the LDAP
1316          backend and don't want their LDAP tree to grow out of
1317          control.
1318       
1319    - 1.15alpha7 :
1320   
1321        - More work done on caching wrt groups.

1330
1331    - 1.15alpha4 :
1332   
1333        - Problem with Python 2.3 fixed. Needs some definitive
1334          modification.
1335         
1336    - 1.15alpha3 :
1337   
1338        - CGI script now tries to restrict view when the
1339          REMOTE_USER environment variable is set. This allows
1340          people to protect its use with .htaccess files.
1341          When unprotected, or if REMOTE_USER is 'root', then
1342          unrestricted access is granted.
1343          NB : REMOTE_USER is automatically set by the web server
1344          (e.g. Apache) when a page with restricted access is viewed.
1345         
1346    - 1.15alpha2 :
1347

1351       
1352    - 1.15alpha1 :
1353   
1354        - Bug fix in SQL code.
1355       
1356    - 1.14 :
1357   
1358        - The PostgreSQL database connection is now always closed before
1359          exit. The LDAP database connection too, but it didn't suffer
1360          from the problem anyway, AFAICT.
1361       
1362    - 1.14beta2 :
1363   
1364        - An LDAP-specific configuration field was introduced, usermail.
1365          Use it to specify which LDAP attribute contains a valid email
1366          address for the user. See sample configuration file for
1367          details.
1368       
1369    - 1.14beta :
1370   
1371        - Two new LDAP-specific configuration fields were introduced,
1372          newuser and newgroup. Use them to specify if you want to add
1373          quota information to existing entries or elsewhere.
1374          See sample configuration file for details.
1375         
1376    - 1.14alpha9 :
1377   
1378        - Documentation improved.
1379       
1380        - pykotme now also prints the user's account balance value
1381          if the user is registered in the Quota Storage and his
1382          limiting factor is "balance".
1383         
1384    - 1.14alpha8 :
1385   
1386        - bin/waitprinter.sh is now included to wait for
1387          SNMP enabled printers to be idle again before
1388          asking for their internal page counter.
1389          See sample configuration file for details.
1390         
1391    - 1.14alpha7 :
1392   
1393        - edpykota now doesn't check if the user/group is above
1394          quota. The check is only done at print time. This
1395          prevents the sending of email messages when creating
1396          user quotas if quota is already reached at creation
1397          time.
1398         
1399    - 1.14alpha6 :
1400   
1401        - Configuration file split and moved to /etc/pykota/pykota.conf
1402          and /etc/pykota/pykotadmin.conf to prevent simple users to
1403          have Read/Write access to the Quota Database.
1404          Don't forget to :
1405         
1406                $ chmod 640 /etc/pykota/pykotadmin.conf
1407               
1408        - storageuser and storageuserpw configuration fields reintroduced
1409          for the same reason.
1410         
1411        - Code cleaning for future implementation of email addresses
1412          support in the PostgreSQL and LDAP backends.
1413         
1414    - 1.14alpha5 :
1415       
1416        - Big bug fixed when changing the prices for a printer
1417       
1418    - 1.14alpha4 :
1419   
1420        - When adding an user, the user itself and its account balance
1421          are now added in the same LDAP entry. Before they were added
1422          as two different LDAP entries.
1423         
1424    - 1.14alpha3 :
1425   
1426        - Email field added to PostgreSQL database. An upgrade script

1436          balance (below 1.0 by default, configurable) are sent
1437          a warning message.
1438         
1439        - All warning messages to users are now configurable. 
1440          NB : Warning messages to the administrator are not.

1443   
1444        - Some small fixes wrt group handling.
1445       
1446        - The whole module code was passed through PyChecker and
1447          several small code inconsistencies were fixed,
1448          as well as a bug in the groups code.
1449         
1450    - 1.13alpha1 :

1497        - LDAP backend works !
1498       
1499        - repykota and warnpykota allow the root user to pass
1500          users or groups names on the command line. Users
1501          and groups names may contain wildcards.
1502         
1503        - repykota and warnpykota only reports or warns the
1504          current user when launched by non-root users.
1505         
1506        - Minor bug fixes. 
1507   
1508    - 1.09alpha1 :
1509   
1510        - More work on LDAP storage backend. Many options
1511          were added to /etc/pykota.conf to give some
1512          hints to the LDAP storage backend.
1513         
1514        - Severe database access optimizations were done by
1515          rewriting most of the Quota Storage backends drivers.
1516     
1517    - 1.08 :
1518   
1519        - Major bug fix wrt LPRng support for remote jobs.
1520       
1521        - Major bug fix wrt increase/decrease account balances.
1522       
1523    - 1.08alpha8 :
1524   
1525        - Code refactoring.
1526       
1527        - A single user/password pair is used to connect
1528          to the database backend. The storageuser configuration
1529          field, and its associated passwords storageuserpw, are
1530          not used anymore.
1531         
1532        - You can now set PyKota in debug mode, see sample configuration 
1533          file for details.
1534          WARNING : only Quota Storage backend queries are logged in
1535          debug mode, for now.
1536       
1537    - 1.08alpha7 :
1538   
1539        - Very latest LDAP schema.
1540       
1541        - Code enhancement wrt easy pluggability of PyKota attributes
1542          and object classes into an existing LDAP directory.
1543       
1544    - 1.08alpha6 :
1545   
1546        - Minor bug corrections
1547       
1548        - More work on LDAP : new schema
1549       
1550    - 1.08alpha5 :
1551   
1552        - More good work on LDAP storage.
1553          repykota now works reasonably well with the sample LDAP directory.
1554       
1555    - 1.08alpha4 :
1556   
1557        - LDAP schema included.
1558          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
1559          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1560          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1561          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1562          MAILING LIST.
1563         
1564    - 1.08alpha3 :
1565   
1566        - External accounting methods were partly rewritten :
1567         
1568          - No more "broken pipe" should happen.
1569         
1570          - They now take care of the number of copies
1571            This may be unneeded though, if the postscript
1572            file already does this, because this would
1573            overcharge users (number of copies counted
1574            two times). NEEDS MORE TESTING.
1575           
1576          - The sample configuration file now contains 
1577            an external accounting method example which should
1578            work with all DSC compliant Postscript files.
1579           
1580        - Some small bugs were fixed.   
1581       
1582    - 1.08alpha2 :
1583   
1584        - Now works with net-snmp v5.0 and above.
1585          It already worked, but the sample configuration
1586          file didn't contain appropriate values...
1587       
1588    - 1.07 : Release of the Shame !
1589   
1590        - The external accounting methods driver was left out of
1591          the CVS tree. Nobody could use it since it wasn't included !
1592         
1593    - 1.06 :
1594   
1595        - Severe bug fixed : if you had a printer in
1596          power saving state which couldn't answer immediately,
1597          a bug was triggered.
1598          It was caused by a bad copy/paste which
1599          forgot to import a Python module at run time.
1600         
1601    - 1.05 :
1602   
1603        - External accounters are finally available !
1604          This means that you can plug any page accounting
1605          method you like by setting the appropriate
1606          'accounter' field in /etc/pykota.conf
1607          See the sample conf/pykota.conf.sample to
1608          learn how to do.
1609         
1610          NB : Both 'external' and 'stupid' accounting methods
1611               account a job size just before *this* job is
1612               sent to the printer.
1613               The original 'querying' method accounts a job
1614               size just before *the next* job is sent to
1615               the printer.
1616       
1617    - 1.05alpha3 :
1618   
1619        - A 'stupid' and unreliable accounting method was
1620          implemented to serve as an example on how to
1621          do this sort of things. This method only counts
1622          the 'showpage' statements in the input data.
1623          See sample configuration file for details.
1624          Pluggable accounting methods work, but I advise
1625          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1626          It is not reliable enough to be used.
1627          Use the 'querying' accounting method instead.
1628         
1629    - 1.05alpha2 :
1630   
1631        - Pluggable accounting methods.
1632       
1633        - Better error handling.
1634       
1635    - 1.05alpha1 :
1636   
1637        - SECURITY file added to help improve PyKota's security.
1638       
1639        - Extracting the printer's internal page counter is now
1640          tried several times, waiting several seconds between
1641          two tries. This lets the time to warm up for some printers
1642          which don't answer when they are sleeping (my Apple
1643          LaserWriter 16/600 PS is in this case, maybe others too)
1644         
1645        - Small display bug fixed in repykota
1646         
1647    - 1.04 :
1648   
1649        - Default print policy for users/groups unknown from
1650          the print quota system is now DENY instead of ALLOW,
1651          since ALLOW can generate inaccurate results
1652          (incorrect job sizes charged to the wrong persons)
1653         
1654        - LPRng support works !
1655       
1656        - A bug was introduced some time ago wrt printers' default
1657          policy for unknown users. It is now corrected.
1658       
1659        - repykota now displays prices per job and per page for each
1660          printer, if they are defined.
1661         
1662        - Minor display bug fixed in repykota.
1663       
1664        - Problem when running repykota with an empty database was fixed.
1665       
1666    - 1.03 :
1667   
1668        - Upgrade script included for earlier versions.
1669          Please look inside the initscripts subdirectory.
1670          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1671         
1672        - repykota now reports account balances too.
1673       
1674        - PyKota now has a nice logo, see the logos
1675          subdirectory.
1676       
1677        - Manual pages were finally updated.
1678       
1679        - Group quotas seem to work now !
1680       
1681        - The new database schema allows to keep an history of all
1682          jobs as well as charge users per page and/or per job,
1683          and track users' account balance.
1684         
1685        - edpykota now accepts much more command line options to 
1686          use the new functionnalities. See edpykota --help for
1687          details.
1688         
1689        - The installation script now allows to install the sample
1690          configuration file during first installation.
1691         
1692        - More group quota code works, but still not finished. 
1693       
1694        - The CGI script displays a link to PyKota's website.
1695       
1696        - The job history is now kept, this will allow per-period
1697          reports in the future.
1698         
1699        - After having modified the quota for an user with edpykota,
1700          a quota check is done to eventually warn the user/admin about
1701          a quota which is too low to print.
1702         
1703        - A workaround is provided for HP Printers : their internal
1704          page counter is only saved to NVRAM in a 10 increment, so
1705          if you switch them off and then on, the reported page counter
1706          may be lower than the real number of pages printed.
1707          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1708          We unconditionnally set the last job's page count to
1709          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1710          in this case.
1711          For a more accurate accounting, never switch your HP printers
1712          off.
1713         
1714        - A fix is provided for printers which only have a volatile 
1715          page counter (reset to 0 every time you switch the printer on)
1716          This should allow PyKota to work reasonably fine with HP Laserjet
1717          4L/5L/6L, not perfect, but better than nothing.
1718          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1719          For a more accurate accounting, never switch your HP printers
1720          off. This is untested, please report any problem.
1721         
1722        - A bug was fixed when edpykota --add was used with users who already
1723          had a quota on the specified printer.
1724         
1725        - A small display bug in repykota was introduced in preliminary
1726          1.03 versions, and fixed later on.
1727         
1728        - Some minor bugs which happened in rare situations were fixed.
1729       
1730        - Support for AppleTalk printers was added, see sample configuration
1731          file for details.
1732         
1733        - Users and group printing can now be controlled (limited) either by 
1734          print quota or by account balance.
1735       
1736    - 1.02 :
1737   
1738        - The installation script now checks for software availability
1739          and in case a software is missing asks the user if he
1740          wants to continue with the installation or abort it.
1741         
1742        - The configuration file pykota.conf is now expected to be
1743          found in /etc instead of in /etc/cups
1744          The installation script prompts the user to see if he
1745          wants to move an old configuration file to the new location
1746          if needed.
1747         
1748        - Improved documentation.
1749       
1750        - You can now set the tcp/ip port on which the Quota Storage
1751          Server is listening, see sample configuration file for details.
1752       
1753        - Better general error handling.
1754       
1755        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1756          included as well.
1757       
1758    - 1.01 :
1759   
1760        - The configuration file now accepts an option   
1761          to choose the recipient(s) of the email messages :
1762         
1763            - DevNull means no one will receive them.
1764            - User means only the user will receive them.
1765            - Admin means only the admin will receive them.
1766            - Both means the User and the Admin will receive them.
1767           
1768        - The configuration file now uses hard-coded default values
1769          when an option is not set. See sample configuration file
1770          for details.
1771         
1772        - Manual pages are included since 1.00, but I forgot to   
1773          add this information to this file.
1774         
1775        - Redistribution terms for the official package have 
1776          softened and are now fully GPL compatible :
1777          unrestricted modification is now allowed even for
1778          the version number.
1779         
1780    - 1.00 :
1781   
1782        - edpykota now accepts a --noquota option. This
1783          disable quota checking while still doing page
1784          accounting. This is really useful for people
1785          who don't want to limit their users but want
1786          to know how much pages they print.
1787         
1788        - Some untested scripts were added to retrieve
1789          the life time page counter of non-SNMP printers.
1790         
1791        - Every directory now has a specific README file. 
1792       
1793    - 0.99 :
1794   
1795        - Under some circumstances while the user wasn't allowed
1796          to print, he didn't receive any email message. It is
1797          now fixed.
1798         
1799        - When an user wasn't allowed to print, the quota for
1800          the previous user wasn't updated. This is now fixed.
1801         
1802    - 0.98 :
1803   
1804        - Correctly handle the case where the printer is switched off.
1805       
1806        - Small bug wrt syslog fixed.
1807       
1808    - 0.97 :
1809   
1810        - edpykota accepts wildcards on its command line for users/groups too
1811          if the --add option is not set, e.g. :
1812         
1813              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1814             
1815        - If no user name is passed at all, then a default wildcard of "*"
1816          which means apply the command on ALL users for this printer is used.
1817         
1818        - Small bug fixes.
1819       
1820    - 0.96 :
1821
1822        - Options requester, policy, admin, adminmail and gracedelay can now
1823          be set either globally or per printer. The printer option has
1824          priority if both are defined.
1825
1826        - More powerful configuration parser.
1827       
1828        - If all options are defined globally, there's no need to
1829          define a section for each printer in the configuration
1830          file anymore. Just define a [global] section and it's ok.
1831
1832    - 0.95 :
1833
1834        - External requesters for printers finally added.
1835
1836        - Full internationalization (english and french are supported)
1837 
1838        - More complete quota usage report
1839
1840        - CGI script to access to the quota usage report
1841
1842        - Several bugs fixed.
1843
1844
1845    - 0.9 :
1846
1847        - First public version
