91          returning to "idle".
92         
93        - Some permissions settings may have prevented cupspykota

115       
116        - Updated some translation files.

119   
120        - Fixed an LPRng specific bug.
121

131    - 1.21alpha27 :
132   
133        - Allows software() (no arguments) to the software accounting
134          directive. This saves a lot of CPU since the job is not
135          parsed again : the precomputed size is used directly in this
136          case.
137         
138        - epykota's --prototype option now works fine with accounts
139          limited by balance.
140         
141    - 1.21alpha26 :
142   
143        - Fixed the handling of the 'maxdenybanners' directive.
144       
145        - Introduced the 'denyduplicates' directive.

150   
151        - The job's size is now always precomputed, even when
152          'enforcement' is not set to 'strict'.
153         
154        - Introduction of the new 'trustjobsize' configuration directive
155          to workaround some problematic printers. See the sample
156          configuration file for details.
157         
158    - 1.21alpha24 :
159   
160        - Big database structure changes. An upgrade script
161          is now included for PostgreSQL. LDAP users may just
162          want to copy the new schema in place.
163         
164        - edpykota now recognizes the -o | --overcharge command line
165          option to set an overcharging or undercharging factor
166          on each print job's cost for a particular user.
167         
168        - repykota's output format has changed an is not limited to 
169          80 characters wide anymore. People who used to parse
170          repykota's output in their own tools are strongly advised
171          to parse dumpykota's output instead.
172         
173        - Introduction of the new 'maxdenybanners' configuration directive
174          to allow up to N (the directive's value) deny banners to be
175          printed even if the print account is forbidden to print.
176         
177        - Better detection of the number of copies in the PostScript parser.
178       
179    - 1.21alpha23 :
180   
181        - Traditional Chinese translation added.
182   
183        - Several fixes and performance improvements with the LDAP backend.
184       
185    - 1.21alpha22 :
186   
187        - edpykota's --delete command line option doesn't consider
188          '*' to be the default argument anymore :-)
189         
190    - 1.21alpha21 :
191   
192        - dumpykota.cgi can now be run as a normal user as opposed to
193          a PyKota administrator. No read access to pykotadmin.conf is
194          necessary anymore. This CGI scripts now honors the REMOTE_USER
195          environment variable just like printquota.cgi does, see
196          the file cgi-bin/README for details.
197          The command line tool dumpykota must still be run by a PyKota
198          administrator.
199         
200        - Fix exception's name error due to a change in recent versions
201          of PygreSQL.   
202         
203    - 1.21alpha20 :
204         
205        - Big bug fix wrt the datelimit field which was never reset.
206         
207    - 1.21alpha19 :
208   
209        - Introduction of the new dumpykota.cgi CGI script, which
210          allows third party tools like phpPrintAnalyzer to be
211          interfaced in real time with PyKota. To use it you
212          may have to change your web server's configuration,
213          please see pykota/cgi-bin/README
214         
215    - 1.21alpha18 :
216   
217        - Now dumpykota can dump the job history into CUPS' page_log
218          format (even when the printing system is LPRng). This allows
219          people to use tools like PrintAnalyzer or phpPrintAnalyzer
220          (two completely different beasts) with PyKota.
221         
222    - 1.21alpha17 :
223     
224        - Fixed field type's name in XML dumps.
225       
226        - Now drops priviledges to user 'pykota' when launched as root
227          (directly or as a CUPS backend), if such an user exists.
228         
229        - Fixed PCL3/4/5 parser for some drivers' output.
230       
231    - 1.21alpha16 :
232   
233        - fixed several recently introduced bugs in LDAP backend code,
234          thanks to Matt Hyclak.
235         
236    - 1.21alpha15 :
237     
238        - Normalized field names between LDAP and PostgreSQL backends
239          in dumpykota's output.
240         
241        - dumpykota filtering capabilities are now supported within
242          the LDAP backend too.
243         
244    - 1.21alpha14 :
245   
246        - dumpykota now supports extended filtering possibilities
247          with the PostgreSQL backend (LDAP support will come soon).
248         
249    - 1.21alpha13 :
250   
251        - Added a --debug command line option to pkpgcounter, so
252          that people may see what really happens, and what will
253          be available in the future :-)
254         
255    - 1.21alpha12 :
256   
257        - Fixed a bug with non standard pkbanner command lines.
258       
259        - Now logs as errors the differences between precomputed and
260          computed job sizes. **CUPS only for now**
261         
262    - 1.21alpha11 :
263   
264        - Now user and group print quota entries can be stored directly
265          below the user or group with the LDAP backend, using them
266          as branches. Thanks to Stefan Wold for the patch.
267          See the sample configuration file for details.
268         
269        - TLS is now supported with the LDAP backend. Thanks to Stefan
270          Wold for the patch.
271          See the sample configuration file for details.
272         
273        - edpkota now accepts the -U | --used value command line argument
274          to preset the page counters to an initial value. Thanks to
275          Wilson Roberto Afonso and Matt Hyclak for the patch.
276         
277    - 1.21alpha10 :
278   
279        - Now automatically reconnects up to three times if the LDAP server
280          returned an error, possibly due to a timeout.
281         
282    - 1.21alpha9 :
283   
284        - Now searches the configuration files in 'pykota' system user's
285          home directory. The 'pykota' system user and group have
286          to be created by the system administrator, and given
287          sufficient permissions to PyKota's configuration files.
288         
289    - 1.21alpha8 :

331         
332    - 1.21alpha1 :
333   
334        - added an IPP messages miniparser. Extraction of the client
335          hostname is now considered to be fiable, at least until
336          the CUPS developpers change something...
337       
338    - 1.20 :
339   
340        - Version number changed.
341

352          in the history.
353         
354        - Minor changes in the debian directory.
355       
356    - 1.20alpha27 :
357   
358        - Fixed many problems with translation files. In particular
359          the Brazilian Portuguese translation file was incorrectly
360          installed into the french "breton" locale directory.
361         
362        - Finished French translation. 
363         
364    - 1.20alpha26 :
365

376          to be a PyKota administrator when another command line
377          option is used.
378         
379        - pkhint doesn't use absolute path to search for helper commands

387       
388        - Now warnpykota only warns users who have ever printed,
389          to not cause confusion to users who have just opened
390          their account.
391       
392        - Prepared help messages for translations.
393       
394    - 1.20alpha23 :
395   
396        - Add workaround for locale problem.
397       
398    - 1.20alpha22 :
399   
400        - Hopefully final fix for data encoding charset.
401       
402        - edpykota now refuse to work if the user is not a PyKota admin.

409          a PyKota administrator (a PyKota administrator is an user
410          allowed to read the pykotadmin.conf file).
411         
412        - Now any PyKota administrator can use repykota and warnpykota
413          with additionnal arguments, not only the root user.
414         
415        - Improved documentation a bit.
416

432         
433        - The description, filename, title, and options fields
434          are now stored as UTF-8 strings in both LDAP and PostgreSQL.

458          'pjl' value in the hardware accounter.
459         
460    - 1.20alpha15 :
461   
462        - LDAP pykotaAccountBalance objects were always created
463          attached to the pykotaUser objects. This is now
464          fixed and the value of balancebase in pykota.conf
465          is now correctly used.
466         
467    - 1.20alpha14 :
468   
469        - Belgian translations added (copy of the french ones).

479        - Hardware accounter now accepts the special
480          'snmp' value, meaning ALL is done from main code
481          without launching any subprocess.
482          You need the http://pysnmp.sf.net Python module
483          for this to work (tested with v3.4.2)
484         
485        - Increased delay between two loops iterations 
486          to 2 seconds in waitprinter.sh to diminish
487          CPU load.
488         
489    - 1.20alpha12 :
490   
491        - waitprinter.sh rewritten from scratch to wait
492          for printer status stabilization.
493       
494    - 1.20alpha11 :
495   
496        - Generic data dumper 'dumpykota' introduced.
497          Works only with PostgreSQL backend for now.
498

511          supported.
512       
513    - 1.20alpha7 :
514   
515        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
516          Needs more work, but no documentation is available.
517       
518    - 1.20alpha6 :
519     
520        - Improved mailandpopup.sh script.
521       
522        - Small fixes for LPRng.
523       
524        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
525          hostname or IP address. Set to 'localhost' when not
526          meaningful.
527         
528        - Fixed issue with how mod_auth_ldap Apache modules
529          fills the REMOTE_USER environment variable.
530         
531        - Fixed a bug in LDAP user deletion code.
532       
533    - 1.20alpha5 :
534     
535        - Introduces the new configuration directive 'onaccountererror'
536          to specify what must be done whenever the software or
537          hardware accounter fails. Allowed values are 'continue' and
538          'stop' (default).
539         
540        - Minor fix in software accounter for a recently introduced
541          problem.
542         
543    - 1.20alpha4 :
544   
545        - Added support for more ghostscript devices in ESC/P2
546          analyzer : stcolor, st800, escp, escpc are now supported.
547         
548    - 1.20alpha3 :
549       
550        - Small improvement in PostScript parser to avoid being
551          fooled by a change in number of copies :
552          The user can't ask for 200 copies of page 1 and 1 copy
553          of page 2 to fool PyKota anymore :
554          this would have been accounted for as 1 copy only, but
555          now the maximum value seen is used.
556         
557        - Relax checks for PCL5 header to accomodate some strange
558          printer drivers.
559         
560        - Now hardware accounting method works like software
561          accounting method wrt the subprocess' output.
562         
563        - Hardware and Software accounting stop the print queue 
564          when the accounting subprocess didn't work. This will
565          be configurable in the near future.
566         
567    - 1.20alpha2 :
568   
569        - Now software accounting method reads accounter's
570          answer until a line with a single integer is
571          obtained or until all of its output has been read.
572          This should fix the problem some people have
573          when strange locale related messages are sent
574          when running subprocesses (Solaris only ?).
575         
576        - First version of ESC/P2 analyzer. Seems to work
577          ok at least with 'epson', 'epsonc', 'eps9mid'
578          and 'esp9high' ghostscript devices. Needs more
579          work to correctly analyze other devices.
580       
581    - 1.20alpha1 :
582   
583        - Fixed problem with number of copies in PCLXL parser.
584       
585        - Fixed problem with number of copies in PCL5 parser,
586          when number of copies was set outside of and before first
587          page.
588       
589        - Added workaround for number of copies directly set in
590          PostScript code.
591         
592        - Added german translation.
593       
594        - Fixed problem on first print for user group quota when
595          "enforcement: strict" is used.
596       
597        - Fixed interpolation problem in french translation.
598       
599    - 1.19 :
600   
601        - Updated existing translations.   
602       
603        - Added final Thai and Greek translations.
604       
605        - Minor last minute bug fixes.
606       
607    - 1.19beta :
608   
609        - LPRng support for both software and hardware accounting seems
610          to be OK.
611         
612        - Translation files fixed because of fuzzy matching problem. 
613       
614        - Fixed path to Swedish translation: 'sv' instead of 'se'.
615       
616        - Added first draft of Thai translation.
617       
618        - Fixed some minor bugs with Pychecker.
619       
620    - 1.19alpha35 :
621   
622        - Generic PDL analyzer now supports Binary PostScript documents
623          in addition to DSC compliant ones.
624       
625    - 1.19alpha34 :
626   
627        - LPRng support : software accounting seems to work fine,
628          but hardware accounting doesn't work yet.
629   
630    - 1.19alpha33 :
631   
632        - pykosd now accepts command line arguments. Enjoy !
633          NB : due to a bug in xosd, you need xosd version 2.2.8
634          or higher if you don't use the default C locale.
635         
636    - 1.19alpha32 :
637   
638        - Early (not working) version of the LPRng support rewrite.
639       
640        - Saner default configuration file.
641       
642    - 1.19alpha31 :
643   
644        - Fixed a double Python2.1 incompatibility with newer versions,
645          which prevented the PCL5 and the PCLXL parsers to work with
646          this older version of Python.
647         
648    - 1.19alpha30 :
649   
650        - Introduction of preliminary version of the pykosd command
651       
652        - Usernames, Groupnames and Printernames can now contain
653          ANY character, expected '/' and '@'.
654       
655        - Integrated most of the Debian work from Sergio
656          Gonz�z Gonz�z
657         
658    - 1.19alpha29 :
659   
660        - PCLXL parser should now correctly handle number of
661          copies set for each page.
662         
663        - Added testsuite for generic PDL analyzer.
664       
665        - Typo fixed in PCLXL parser.
666       
667        - Correctly dispatches error messages depending on the
668          situation : tools which can be run interactively will
669          ALWAYS output their logs to stderr, excepted for
670          their DEBUG messages, for which the "logger:"
671          directive as set in pykota.conf will be honored.
672          Tools which can't be run interactively will ALWAYS
673          honor the "logger:" directive as set in pykota.conf
674         
675    - 1.19alpha28 :
676   
677        - The description field for printers can now be set,
678          and is displayed in reports.
679         
680        - Fixed a small problem in SQL backend code.
681         
682        - Improved pkhint
683       
684        - First working PCL6 (aka PCLXL) parser !
685          Doesn't handle copies yet.
686       
687    - 1.19alpha27 :
688   
689        - Additionnal 10% speed increase in PCL5 parser for GhostScript
690          generated files (untested yet with other PCL files).
691         
692        - Reintroduced the use of mmap in PCL5 parser : this speedups
693          PCL5 parsing by almost 4 times.
694          This 4x with the 3x below give us in fact a twelvefold increase
695          in performance for PCL5 parsing !
696         
697        - The Python accelerator Psyco is now used if available
698          in the generic PDL parser : it speedups PCL5 parsing by
699          almost three times automagically.
700         
701    - 1.19alpha26 :
702   
703        - Fixed PCL5 parser according to the sources of rastertohp.
704       
705        - Fixed number of copies handling in PCL5 parser : the number
706          of copies could vary from page to page.
707         
708        - Added more debug information to PCLXL parser. 
709       
710    - 1.19alpha25 :
711   
712        - Added new "description" field to printers in both
713          PostgreSQL and LDAP. No code to handle this yet.
714         
715        - Reversed the fix for power save mode in printers : 
716          no paper or tray open would have caused people to
717          be undercharged.
718         
719        - Preliminary version of MySQL initialization script.
720         
721    - 1.19alpha24 :
722   
723        - Native PDF parsing code now works perfectly with
724          Python 2.1 and above, and is way faster than before.
725          GhostScript is not used anymore to convert PDF to PS,
726          because PDF is parsed directly.
727         
728    - 1.19alpha23 :
729   
730        - Fixed waitprinter.sh wrt PowerSave mode and some
731          printers. Thanks to Ryan Suarez.
732       
733        - Smart PDL analyzer now recognizes PDF too : two
734          PDF parsing methods are used : a native one which
735          is very fast but requires Python 2.3 or above, and
736          a slower one which uses Ghostscript. PyKota detects
737          automatically which method to use depending on your
738          version of Python.
739       
740        - All tracebacks now include PyKota's version number.
741         
742    - 1.19alpha22 :
743   
744        - Ensures that the file pointer for job's data is
745          reset to the start of the job's datas after the
746          job's size pre-computation phase.
747         
748        - Improved PostScript detection code for bad drivers
749          which don't correctly switch languages between PJL
750          and PS.
751       
752        - Even better debugging code.
753       
754    - 1.19alpha21 :
755   
756        - Additionnal check.
757       
758    - 1.19alpha20 :
759   
760        - More complete logging messages wrt accounters.
761       
762        - Now catches early failures occuring when the configuration
763          files are parsed.
764       
765    - 1.19alpha19 :
766   
767        - Fixed over-verbose exits when displaying help
768          or version.
769         
770        - Extended some PATH in the shell scripts 
771       
772        - Deleting an user now also deletes his payments history.
773       
774        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
775          cause problems.
776
777    - 1.19alpha18 :
778   
779        - History of payments is now stored in the database, and
780          updated each time an user's balance is modified with
781          edpykota --balance. This history represents each time
782          the user was given some positive or negative credit,
783          but doesn't reflect price paid for jobs, which appear
784          in the jobs history instead.
785         
786        - Jobs history web reports now include the job's size in
787          bytes. Also columns were reordered to render the report
788          more easily readable.
789         
790    - 1.19alpha17 :
791   
792        - Mysterious bug (program exited unexpectedly without leaving
793          any log message) which occured once in a while when
794          cancelling jobs should be fixed now.
795         
796        - New 'crashrecipient' directive. Disabled by 
797          default. See sample configuration file to see how
798          to activate it. It is suggested that you activate it.
799         
800        - New PYKOTAJOBSIZEBYTES environment variable exported, 
801          which contains the job's size in bytes. Empty jobs
802          are now denied. This value is now stored in the job
803          history (but not yet displayed from the web interface)
804         
805        - Preliminary work on payments storage : the PostgreSQL 
806          and LDAP schemas should be OK now, but no code is written
807          yet to support this functionnality.
808         
809    - 1.19alpha16 :
810   
811        - the newuser and newgroup LDAP specific directives now accept
812          a second parameter to attach(), "fail" or "warn". If no entry
813          is found to attach PyKota attributes to, and "fail" was used,
814          then action is aborted and program exits in error. If "warn"
815          is used, a new entry is created but a warning message is logged.
816         
817        - The job's originating hostname is now stored in the database,
818          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
819       
820    - 1.19alpha15 :
821   
822        - The old pykota filter is now removed. This means that
823          currently PyKota doesn't support LPRng anymore, but
824          LPRng support will be re-added, improved, in the near future.
825         
826    - 1.19alpha14 :
827   
828        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
829          are now exported as environment variables.
830         
831        - Heavy CPU usage is now completely fixed it seems, by
832          introducing some 0.01 second sleeping when nothing to do.
833         
834        - Pre-computation of the job's size is now only
835          done when enforcement is "STRICT", this saves
836          CPU for people who don't want to use this new
837          feature.
838         
839        - New 'enforcement' directive which accepts either
840          STRICT or LAXIST. See sample configuration file
841          for details.
842         
843    - 1.19alpha13 :
844   
845        - Get back to an old version of the polling loop which
846          worked fine, but non-optimally. Will be optimized
847          as time permits.
848         
849    - 1.19alpha12 :
850   
851        - Job's size is now precomputed unconditionnally using
852          the generic PDL analyzer.
853          NB : This value is not yet used to pre-allow/deny the
854          job.
855       
856    - 1.19alpha11 :
857   
858        - The pykota filter is now completely deprecated and
859          can't be used anymore. LPRng users MUST download
860          an older version of PyKota. CUPS users MUST use
861          cupspykota. Better support for LPRng will come
862          in the near future.
863         
864    - 1.19alpha10 :
865   
866        - pykotme now uses generic PDL Analyzer directly instead
867          of spawning a new process.
868         
869        - Improvements to generic PDL Analyzer.
870       
871        - 25% Speedup in PCL parser. Getting more of the Python version
872          will probably be difficult, since the completely table driven
873          parser I wrote is slower than the original algorithm. Then,
874          the original algorithm is still used for now.
875          Probable that more speed could be achieved using mmap, at the
876          expense of severe memory consumption.
877       
878        - configuration simplifications : the "accounter" directive's
879          'hardware' arguments now accepts what was in the "requester"
880          directive as it's content. The "requester" directive is not
881          supported anymore. See sample configuration file for details.
882       
883    - 1.19alpha9 :
884       
885        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
886       
887        - pykotaOptions LDAP attribute now accepts non-ascii characters
888          too.
889         
890        - First try at cupspykota main loop rewrite
891       
892    - 1.19alpha8 :
893   
894        - 'querying' accounting method is now called 'hardware'
895       
896        - 'external' accounting method is now called 'software'
897       
898        - 'stupid' accounting method doesn't exist anymore
899       
900        - 'snmp' requester doesn't exist anymore
901       
902        - code simplifications in external requester
903       
904    - 1.19alpha7 :
905     
906        - Database schema change (both LDAP and PostgreSQL) to
907          allow storage of the job-originating-hostname attribute.
908          An SQL upgrade script is present. The code is not yet
909          capable of setting/retrieving this attribute. Support
910          for this functionnality will be added in the future.
911         
912    - 1.19alpha6 :
913   
914        - problems connecting to SMTP servers are now catched.
915       
916        - pykotme now uses pkpgcounter to compute the size of the
917          job. This modification adds PCL5 and soon PCLXL (PCL6)
918          support. You can now get quotes for PCL in addition to
919          PostScript.
920         
921        - pkpgcounter now includes first try at PCLXL parser. 
922          It is currently disabled until it's finished.
923         
924    - 1.19alpha5 :
925   
926        - cupspykota polling loop fix for MacOSX (at least)
927       
928        - logging subsystem now logs PID too, to ease diagnosing
929          problems under heavy load.
930         
931        - pkpgcounter enhancements.
932       
933        - pkprinters --skipexisting now tells pkprinters to not
934          modify existing printers when --add is used.
935          pkprinters logs a warning message whenever --add is
936          used and a printer already exists.
937         
938        - LDAP schema now allows accented chars in pykotaFileName
939          and pykotaTitle attributes.
940       
941    - 1.19alpha4 :
942   
943        - a bad copy&paste prevented pkpgcounter to work at all, this
944          is now fixed.
945         
946        - improved PCL support in pkpgcounter, with the use of
947          HP PCL/PJL Reference Set
948          PCL5 Printer Language Technical Quick Reference Guide
949       
950        - pkpgcounter now uses mmap to speed things up : duration
951          is halved with the sample 87 pages PCL document I use for
952          testing.
953         
954    - 1.19alpha3 :
955   
956        - pkprinters now accepts the --list command line argument
957          to list informations about printers.
958         
959    - 1.19alpha2 :
960   
961        - pkpgcounter is now included as a smart external
962          accounter which can handle both PostScript and PCL.
963         
964    - 1.19alpha1 :
965   
966        - PYKOTALIMITBY environment variable is now exported too.
967       
968        - Inclusion of Michele Baldessari's work on autotools.
969       
970    - 1.18 :
971   
972        - Improved documentation
973       
974    - 1.18beta2 :
975     
976        - Fix for raw jobs with cupspykota
977       
978    - 1.18beta :
979   
980        - Small fix for new waitprinter.sh script
981       
982        - Better tracebacks on error conditions
983       
984        - Improved translations
985       
986        - Improved documentation
987       
988    - 1.18alpha15 :
989
990        - waitprinter.sh replaced by a new and possibly faster
991          and more powerful one.
992   
993        - Names can now begin with a digit.
994       
995        - Stability improvement for quotas set on printers groups.
996       
997    - 1.18alpha14 :
998   
999        - Catches more (all ?) problems with SMTP servers instead
1000          of breaking.
1001         
1002        - Italian translation added.
1003       
1004    - 1.18alpha13 :
1005   
1006        - Pre and Post hooks are now available in the pykota
1007          filter as well.
1008         
1009        - The pykota filter doesn't check last user's quota
1010          anymore when delayed hardware accounting is used :
1011          this will be done anyway the next time the last
1012          user will print again. This saves some database
1013          queries which are unneeded.
1014       
1015    - 1.18alpha12 :
1016   
1017        - Pre and Post hooks to external commands with many
1018          many environment variables available are useable
1019          from the cupspykota backend.
1020          See sample configuration file for details and help.
1021         
1022    - 1.18alpha11 :

1032    - 1.18alpha9 :
1033   
1034        - Fix for LDAP problem when job price was 0.
1035       
1036        - Fix for empty user groups with LDAP.
1037       
1038        - Preliminary version of the snmpprinterstatus command added.
1039       
1040    - 1.18alpha8 :
1041   
1042        - Don't retrieve data when not needed.
1043          This avoids many database queries.
1044       
1045    - 1.18alpha7 :
1046   
1047        - New experimental ldapcache directive to improve
1048          LDAP caching.

1058    - 1.18alpha5 :
1059   
1060        - Debian packaging specific files, contributed by
1061          Peter Hawkins are now included in the project's tree.
1062         
1063        - Preliminary work on future low-level LDAP caching to speed
1064          up modifications (at least).
1065         
1066    - 1.18alpha4 :
1067   
1068        - Applied some of the modifications suggested by
1069          Peter Hawkins, for better Debian integration.
1070          Most notably cupspykota, pykota, and the shell
1071          scripts are now installed into /usr/share/pykota
1072          instead of into /usr/bin
1073          BEWARE : double check that your symbolic link
1074          to cupspykota is correct, and that your pykota.conf
1075          file use correct path for the shell scripts like
1076          waitprinter.sh and al.
1077         
1078        - pkhint command added, to help in configuring correct
1079          accounting method for PyKota.

1115          added to the documentation. Doesn't yet document v1.16
1116          though.
1117       
1118        - Portuguese Portuguese translation replaces Brazilian
1119          Portuguese Translation. Brazilian portuguese
1120          translation is still available under the 'br' locale.
1121       
1122    - 1.16beta3 :
1123

1127       
1128    - 1.16beta2 :
1129   
1130        - Small fix for job cancelling code while job already
1131          printing in CUPS backend.
1132         
1133        - Big fix wrt printing policies for unknown users. 
1134       
1135    - 1.16beta1 :
1136   
1137        - Manpages upgraded.
1138       
1139    - 1.16alpha26 :
1140   
1141        - Job price is now computed like this :
1142       
1143          SUM((NbPages * PricePerPage) + PricePerJob)
1144         
1145          For current printer and all the printers groups it is
1146          a member of, if any.
1147         
1148          This may be difficult to grasp, but offers unprecedented
1149          flexibility.
1150         
1151    - 1.16alpha25 :
1152   
1153        - Email address can be set at user creation time,

1165          automatically add printers on first print.
1166       
1167    - 1.16alpha23 :
1168   
1169        - Fixed potential accuracy problem if a user printed on
1170          several printers at the very same time.
1171

1189       
1190    - 1.16alpha18 :
1191   
1192        - Initial code for printer groups support. Printer groups have
1193          to be added with external tools like psql or gq for example.
1194          Printer groups seems to work fine with users. Untested with user
1195          groups for now.
1196
1197        - Several minor visual problems fixed in reports.
1198       
1199        - Fixed a bug in LDAP date handling.
1200

1205          for details.
1206       
1207        - Several environment variables are now exported when executing
1208          external commands (accounters, requesters, mailers) :
1209           
1210            PYKOTAUSERNAME => user who is printing
1211            PYKOTAPRINTERNAME => printer on which the job is being sent
1212            PYKOTATITLE => Job's title
1213            PYKOTAFILENAME => Job's filename
1214            PYKOTACOPIES => number of copies asked
1215            PYKOTAOPTIONS => print command options (-o with CUPS)
1216         
1217    - 1.16alpha17 :
1218   
1219        - Added portugues translation.
1220       
1221        - Major code refactoring in accounters.
1222       
1223    - 1.16alpha16 :
1224   
1225        - Code refactoring, and addition of a real HTML reporter, to
1226          have nice looking and useful web based reports (in the future).
1227       
1228        - Added utolower configuration option to convert all usernames
1229          to lowercase during printing.
1230         
1231    - 1.15alpha15 :
1232   
1233        - Now includes the papwaitprinter.sh shell script to wait for
1234          AppleTalk enabled printers.
1235         
1236    - 1.16alpha14 :
1237   
1238        - Now printing on a printer not defined in the Quota Storage,
1239          results in the job being cancelled or stopped, depending
1240          on the printing system.
1241         
1242    - 1.16alpha13 :
1243   
1244        - Small bugfix wrt Python v2.1
1245       
1246        - If username is an empty string, user root is assumed.
1247       
1248        - 'postgresql' is not recognized anymore as a storage backend,
1249          you have to use 'pgstorage' instead. 'postgresql' used to
1250          be supported for compatibility with very old PyKota versions,
1251          this is not the case anymore.
1252         
1253    - 1.16alpha12 :
1254   
1255        - Job price added to job history, to keep accounting correct
1256          if a printer price per page or per job is modified and the
1257          history is not reset : the history would have given a false
1258          amount of money charged before the printer's prices were
1259          modified, this addition solves the problem.
1260         
1261    - 1.16alpha11 :
1262   
1263        - Some preliminary modifications to the database structure for
1264          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1265          database is now provided. LDAP attributes now support
1266          eq, pres and sub indexes.
1267         
1268        - Job history now contains additional informations : 
1269          number of copies, filename, title and print options.
1270         
1271    - 1.16alpha10 :
1272       
1273        - Some modifications done to external policy handling.
1274          See sample configuration file for details.
1275   
1276        - Spanish translation added.
1277       
1278    - 1.16alpha9 :
1279   
1280        - mailto can be set to external(...) to warn users above
1281          quota with any command of your choice (e.g. linpopup).
1282          Several parameters are available, see sample configuration
1283          file for details.
1284         
1285    - 1.16alpha8 :
1286   
1287        - Now cupspykota transmits SIGTERMS to the original 
1288          backend when the user deletes a job being processed.
1289         
1290        - The documentation is now licensed under the terms of the
1291          GNU GPL too.
1292         
1293    - 1.16alpha7 :
1294   
1295        - The CUPS backend is now fully functionnal (it seems).
1296       
1297        - From now on, the use of the pykota filter with CUPS
1298          is deprecated. The pykota filter still has to be
1299          used with LPRng though.
1300       
1301    - 1.16alpha6 :
1302   
1303        - Bug fixed : when edpykota was used to add a printer
1304          with no user or group name, a bad user/group name "*" was
1305          added to the database.
1306         
1307    - 1.16alpha5 :
1308   
1309        - New CUPS backend supports device enumeration !
1310          This means that NO manual CUPS configuration has to
1311          be done. All can now be done from CUPS web interface.
1312       
1313    - 1.16alpha4 :
1314   
1315        - New CUPS backend added.
1316       
1317    - 1.16alpha3 :
1318       
1319        - Minimal FAQ document added.

1328       
1329        - More complete error messages in case of LDAP operation failure.
1330       
1331    - 1.15 :
1332     
1333        - Documentation improved.
1334       
1335    - 1.15beta :
1336   
1337        - Command line tools now accept multiple printer
1338          names or wildcards, separated with commas.
1339         
1340    - 1.15alpha9 :
1341   
1342        - External policy can be used to auto-add unknown users
1343          and any other interesting things you may want to do.
1344          WARNING : You can't auto-add printers for now.
1345          They have to be created manually before.
1346          Look at sample configuration file for examples.
1347         
1348    - 1.15alpha8 :
1349   
1350        - Job history can be disabled if needed.
1351          This feature may be useful for people who use the LDAP
1352          backend and don't want their LDAP tree to grow out of
1353          control.
1354       
1355    - 1.15alpha7 :
1356   
1357        - More work done on caching wrt groups.
1358

1365        - Caching mechanism for all database queries.
1366
1367    - 1.15alpha4 :
1368   
1369        - Problem with Python 2.3 fixed. Needs some definitive
1370          modification.
1371         
1372    - 1.15alpha3 :
1373   
1374        - CGI script now tries to restrict view when the
1375          REMOTE_USER environment variable is set. This allows
1376          people to protect its use with .htaccess files.
1377          When unprotected, or if REMOTE_USER is 'root', then
1378          unrestricted access is granted.
1379          NB : REMOTE_USER is automatically set by the web server
1380          (e.g. Apache) when a page with restricted access is viewed.
1381         
1382    - 1.15alpha2 :
1383   
1384        - Better detection of LPRng.
1385       
1386        - Outputs a warning if printing system is unknown.
1387       
1388    - 1.15alpha1 :
1389   
1390        - Bug fix in SQL code.
1391       
1392    - 1.14 :
1393   
1394        - The PostgreSQL database connection is now always closed before
1395          exit. The LDAP database connection too, but it didn't suffer
1396          from the problem anyway, AFAICT.
1397       
1398    - 1.14beta2 :
1399   
1400        - An LDAP-specific configuration field was introduced, usermail.
1401          Use it to specify which LDAP attribute contains a valid email
1402          address for the user. See sample configuration file for
1403          details.
1404       
1405    - 1.14beta :
1406   
1407        - Two new LDAP-specific configuration fields were introduced,
1408          newuser and newgroup. Use them to specify if you want to add
1409          quota information to existing entries or elsewhere.
1410          See sample configuration file for details.
1411         
1412    - 1.14alpha9 :
1413   
1414        - Documentation improved.
1415       
1416        - pykotme now also prints the user's account balance value
1417          if the user is registered in the Quota Storage and his
1418          limiting factor is "balance".
1419         
1420    - 1.14alpha8 :
1421   
1422        - bin/waitprinter.sh is now included to wait for
1423          SNMP enabled printers to be idle again before
1424          asking for their internal page counter.
1425          See sample configuration file for details.
1426         
1427    - 1.14alpha7 :
1428   
1429        - edpykota now doesn't check if the user/group is above
1430          quota. The check is only done at print time. This
1431          prevents the sending of email messages when creating
1432          user quotas if quota is already reached at creation
1433          time.
1434         
1435    - 1.14alpha6 :
1436   
1437        - Configuration file split and moved to /etc/pykota/pykota.conf
1438          and /etc/pykota/pykotadmin.conf to prevent simple users to
1439          have Read/Write access to the Quota Database.
1440          Don't forget to :
1441         
1442                $ chmod 640 /etc/pykota/pykotadmin.conf
1443               
1444        - storageuser and storageuserpw configuration fields reintroduced
1445          for the same reason.
1446         
1447        - Code cleaning for future implementation of email addresses
1448          support in the PostgreSQL and LDAP backends.
1449         
1450    - 1.14alpha5 :
1451       
1452        - Big bug fixed when changing the prices for a printer
1453       
1454    - 1.14alpha4 :
1455   
1456        - When adding an user, the user itself and its account balance
1457          are now added in the same LDAP entry. Before they were added
1458          as two different LDAP entries.
1459         
1460    - 1.14alpha3 :
1461   
1462        - Email field added to PostgreSQL database. An upgrade script
1463          is included in initscripts/postgresql.

1467        - Typo fixed when using the --prototype option to edpykota
1468       
1469    - 1.14alpha1 :
1470   
1471        - Poor man's treshold included : users with a low account
1472          balance (below 1.0 by default, configurable) are sent
1473          a warning message.
1474         
1475        - All warning messages to users are now configurable. 
1476          NB : Warning messages to the administrator are not.
1477       
1478    - 1.13 :
1479   
1480        - Some small fixes wrt group handling.
1481       
1482        - The whole module code was passed through PyChecker and
1483          several small code inconsistencies were fixed,
1484          as well as a bug in the groups code.
1485         
1486    - 1.13alpha1 :
1487   
1488        - Bug fix wrt LDAP.
1489

1532       
1533        - LDAP backend works !
1534       
1535        - repykota and warnpykota allow the root user to pass
1536          users or groups names on the command line. Users
1537          and groups names may contain wildcards.
1538         
1539        - repykota and warnpykota only reports or warns the
1540          current user when launched by non-root users.
1541         
1542        - Minor bug fixes. 
1543   
1544    - 1.09alpha1 :
1545   
1546        - More work on LDAP storage backend. Many options
1547          were added to /etc/pykota.conf to give some
1548          hints to the LDAP storage backend.
1549         
1550        - Severe database access optimizations were done by
1551          rewriting most of the Quota Storage backends drivers.

1558       
1559    - 1.08alpha8 :
1560   
1561        - Code refactoring.
1562       
1563        - A single user/password pair is used to connect
1564          to the database backend. The storageuser configuration
1565          field, and its associated passwords storageuserpw, are
1566          not used anymore.
1567         
1568        - You can now set PyKota in debug mode, see sample configuration 
1569          file for details.
1570          WARNING : only Quota Storage backend queries are logged in
1571          debug mode, for now.
1572       
1573    - 1.08alpha7 :
1574   
1575        - Very latest LDAP schema.
1576       
1577        - Code enhancement wrt easy pluggability of PyKota attributes
1578          and object classes into an existing LDAP directory.
1579       
1580    - 1.08alpha6 :
1581   
1582        - Minor bug corrections
1583       
1584        - More work on LDAP : new schema
1585       
1586    - 1.08alpha5 :
1587   
1588        - More good work on LDAP storage.
1589          repykota now works reasonably well with the sample LDAP directory.
1590       
1591    - 1.08alpha4 :
1592   
1593        - LDAP schema included.
1594          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
1595          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1596          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1597          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1598          MAILING LIST.
1599         
1600    - 1.08alpha3 :
1601   
1602        - External accounting methods were partly rewritten :
1603         
1604          - No more "broken pipe" should happen.
1605         
1606          - They now take care of the number of copies
1607            This may be unneeded though, if the postscript
1608            file already does this, because this would
1609            overcharge users (number of copies counted
1610            two times). NEEDS MORE TESTING.
1611           
1612          - The sample configuration file now contains 
1613            an external accounting method example which should
1614            work with all DSC compliant Postscript files.
1615           
1616        - Some small bugs were fixed.   
1617       
1618    - 1.08alpha2 :
1619   
1620        - Now works with net-snmp v5.0 and above.
1621          It already worked, but the sample configuration
1622          file didn't contain appropriate values...
1623       
1624    - 1.07 : Release of the Shame !
1625   
1626        - The external accounting methods driver was left out of
1627          the CVS tree. Nobody could use it since it wasn't included !
1628         
1629    - 1.06 :
1630   
1631        - Severe bug fixed : if you had a printer in
1632          power saving state which couldn't answer immediately,
1633          a bug was triggered.
1634          It was caused by a bad copy/paste which
1635          forgot to import a Python module at run time.
1636         
1637    - 1.05 :
1638   
1639        - External accounters are finally available !
1640          This means that you can plug any page accounting
1641          method you like by setting the appropriate
1642          'accounter' field in /etc/pykota.conf
1643          See the sample conf/pykota.conf.sample to
1644          learn how to do.
1645         
1646          NB : Both 'external' and 'stupid' accounting methods
1647               account a job size just before *this* job is
1648               sent to the printer.
1649               The original 'querying' method accounts a job
1650               size just before *the next* job is sent to
1651               the printer.
1652       
1653    - 1.05alpha3 :
1654   
1655        - A 'stupid' and unreliable accounting method was
1656          implemented to serve as an example on how to
1657          do this sort of things. This method only counts
1658          the 'showpage' statements in the input data.
1659          See sample configuration file for details.
1660          Pluggable accounting methods work, but I advise
1661          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1662          It is not reliable enough to be used.
1663          Use the 'querying' accounting method instead.
1664         
1665    - 1.05alpha2 :
1666   
1667        - Pluggable accounting methods.
1668       
1669        - Better error handling.
1670       
1671    - 1.05alpha1 :
1672   
1673        - SECURITY file added to help improve PyKota's security.
1674       
1675        - Extracting the printer's internal page counter is now
1676          tried several times, waiting several seconds between
1677          two tries. This lets the time to warm up for some printers
1678          which don't answer when they are sleeping (my Apple
1679          LaserWriter 16/600 PS is in this case, maybe others too)
1680         
1681        - Small display bug fixed in repykota
1682         
1683    - 1.04 :
1684   
1685        - Default print policy for users/groups unknown from
1686          the print quota system is now DENY instead of ALLOW,
1687          since ALLOW can generate inaccurate results
1688          (incorrect job sizes charged to the wrong persons)
1689         
1690        - LPRng support works !
1691       
1692        - A bug was introduced some time ago wrt printers' default
1693          policy for unknown users. It is now corrected.
1694       
1695        - repykota now displays prices per job and per page for each
1696          printer, if they are defined.
1697         
1698        - Minor display bug fixed in repykota.
1699       
1700        - Problem when running repykota with an empty database was fixed.
1701       
1702    - 1.03 :
1703   
1704        - Upgrade script included for earlier versions.
1705          Please look inside the initscripts subdirectory.
1706          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1707         
1708        - repykota now reports account balances too.
1709       
1710        - PyKota now has a nice logo, see the logos
1711          subdirectory.
1712       
1713        - Manual pages were finally updated.
1714       
1715        - Group quotas seem to work now !
1716       
1717        - The new database schema allows to keep an history of all
1718          jobs as well as charge users per page and/or per job,
1719          and track users' account balance.
1720         
1721        - edpykota now accepts much more command line options to 
1722          use the new functionnalities. See edpykota --help for
1723          details.
1724         
1725        - The installation script now allows to install the sample
1726          configuration file during first installation.
1727         
1728        - More group quota code works, but still not finished. 
1729       
1730        - The CGI script displays a link to PyKota's website.
1731       
1732        - The job history is now kept, this will allow per-period
1733          reports in the future.
1734         
1735        - After having modified the quota for an user with edpykota,
1736          a quota check is done to eventually warn the user/admin about
1737          a quota which is too low to print.
1738         
1739        - A workaround is provided for HP Printers : their internal
1740          page counter is only saved to NVRAM in a 10 increment, so
1741          if you switch them off and then on, the reported page counter
1742          may be lower than the real number of pages printed.
1743          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1744          We unconditionnally set the last job's page count to
1745          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1746          in this case.
1747          For a more accurate accounting, never switch your HP printers
1748          off.
1749         
1750        - A fix is provided for printers which only have a volatile 
1751          page counter (reset to 0 every time you switch the printer on)
1752          This should allow PyKota to work reasonably fine with HP Laserjet
1753          4L/5L/6L, not perfect, but better than nothing.
1754          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1755          For a more accurate accounting, never switch your HP printers
1756          off. This is untested, please report any problem.
1757         
1758        - A bug was fixed when edpykota --add was used with users who already
1759          had a quota on the specified printer.
1760         
1761        - A small display bug in repykota was introduced in preliminary
1762          1.03 versions, and fixed later on.
1763         
1764        - Some minor bugs which happened in rare situations were fixed.
1765       
1766        - Support for AppleTalk printers was added, see sample configuration
1767          file for details.
1768         
1769        - Users and group printing can now be controlled (limited) either by 
1770          print quota or by account balance.
1771       
1772    - 1.02 :
1773   
1774        - The installation script now checks for software availability
1775          and in case a software is missing asks the user if he
1776          wants to continue with the installation or abort it.
1777         
1778        - The configuration file pykota.conf is now expected to be
1779          found in /etc instead of in /etc/cups
1780          The installation script prompts the user to see if he
1781          wants to move an old configuration file to the new location
1782          if needed.
1783         
1784        - Improved documentation.
1785       
1786        - You can now set the tcp/ip port on which the Quota Storage
1787          Server is listening, see sample configuration file for details.
1788       
1789        - Better general error handling.
1790       
1791        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1792          included as well.
1793       
1794    - 1.01 :
1795   
1796        - The configuration file now accepts an option   
1797          to choose the recipient(s) of the email messages :
1798         
1799            - DevNull means no one will receive them.
1800            - User means only the user will receive them.
1801            - Admin means only the admin will receive them.
1802            - Both means the User and the Admin will receive them.
1803           
1804        - The configuration file now uses hard-coded default values
1805          when an option is not set. See sample configuration file
1806          for details.
1807         
1808        - Manual pages are included since 1.00, but I forgot to   
1809          add this information to this file.
1810         
1811        - Redistribution terms for the official package have 
1812          softened and are now fully GPL compatible :
1813          unrestricted modification is now allowed even for
1814          the version number.
1815         
1816    - 1.00 :
1817   
1818        - edpykota now accepts a --noquota option. This
1819          disable quota checking while still doing page
1820          accounting. This is really useful for people
1821          who don't want to limit their users but want
1822          to know how much pages they print.
1823         
1824        - Some untested scripts were added to retrieve
1825          the life time page counter of non-SNMP printers.
1826         
1827        - Every directory now has a specific README file. 
1828       
1829    - 0.99 :
1830   
1831        - Under some circumstances while the user wasn't allowed
1832          to print, he didn't receive any email message. It is
1833          now fixed.
1834         
1835        - When an user wasn't allowed to print, the quota for
1836          the previous user wasn't updated. This is now fixed.
1837         
1838    - 0.98 :
1839   
1840        - Correctly handle the case where the printer is switched off.
1841       
1842        - Small bug wrt syslog fixed.
1843       
1844    - 0.97 :
1845   
1846        - edpykota accepts wildcards on its command line for users/groups too
1847          if the --add option is not set, e.g. :
1848         
1849              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1850             
1851        - If no user name is passed at all, then a default wildcard of "*"
1852          which means apply the command on ALL users for this printer is used.
1853         
1854        - Small bug fixes.
1855       
1856    - 0.96 :
1857
1858        - Options requester, policy, admin, adminmail and gracedelay can now
1859          be set either globally or per printer. The printer option has
1860          priority if both are defined.
1861
1862        - More powerful configuration parser.
1863       
1864        - If all options are defined globally, there's no need to
1865          define a section for each printer in the configuration
1866          file anymore. Just define a [global] section and it's ok.
1867
1868    - 0.95 :
1869
1870        - External requesters for printers finally added.
1871
1872        - Full internationalization (english and french are supported)
1873 
1874        - More complete quota usage report
1875
1876        - CGI script to access to the quota usage report
1877
1878        - Several bugs fixed.
1879
1880
1881    - 0.9 :
1882
1883        - First public version
