22PyKota NEWS :
23
24    - 1.19alpha10 :
25   
26        - configuration simplifications : the "accounter" directive's
27          'hardware' arguments now accepts what was in the "requester"
28          directive as it's content. The "requester" directive is not
29          supported anymore. See sample configuration file for details.
30       
31    - 1.19alpha9 :
32       
33        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
34       
35        - pykotaOptions LDAP attribute now accepts non-ascii characters
36          too.
37         
38        - First try at cupspykota main loop rewrite
39       
40    - 1.19alpha8 :
41   
42        - 'querying' accounting method is now called 'hardware'
43       
44        - 'external' accounting method is now called 'software'
45       
46        - 'stupid' accounting method doesn't exist anymore
47       
48        - 'snmp' requester doesn't exist anymore
49       
50        - code simplifications in external requester
51       
52    - 1.19alpha7 :
53     
54        - Database schema change (both LDAP and PostgreSQL) to
55          allow storage of the job-originating-hostname attribute.
56          An SQL upgrade script is present. The code is not yet
57          capable of setting/retrieving this attribute. Support
58          for this functionnality will be added in the future.
59         
60    - 1.19alpha6 :
61   
62        - problems connecting to SMTP servers are now catched.
63       
64        - pykotme now uses pkpgcounter to compute the size of the
65          job. This modification adds PCL5 and soon PCLXL (PCL6)
66          support. You can now get quotes for PCL in addition to
67          PostScript.
68         
69        - pkpgcounter now includes first try at PCLXL parser. 
70          It is currently disabled until it's finished.

73   
74        - cupspykota polling loop fix for MacOSX (at least)
75       
76        - logging subsystem now logs PID too, to ease diagnosing
77          problems under heavy load.

79        - pkpgcounter enhancements.
80       
81        - pkprinters --skipexisting now tells pkprinters to not
82          modify existing printers when --add is used.
83          pkprinters logs a warning message whenever --add is
84          used and a printer already exists.
85         
86        - LDAP schema now allows accented chars in pykotaFileName
87          and pykotaTitle attributes.
88       
89    - 1.19alpha4 :
90   
91        - a bad copy&paste prevented pkpgcounter to work at all, this
92          is now fixed.
93         
94        - improved PCL support in pkpgcounter, with the use of
95          HP PCL/PJL Reference Set
96          PCL5 Printer Language Technical Quick Reference Guide
97       
98        - pkpgcounter now uses mmap to speed things up : duration
99          is halved with the sample 87 pages PCL document I use for
100          testing.
101         
102    - 1.19alpha3 :
103   
104        - pkprinters now accepts the --list command line argument
105          to list informations about printers.
106         
107    - 1.19alpha2 :

109        - pkpgcounter is now included as a smart external
110          accounter which can handle both PostScript and PCL.
111         
112    - 1.19alpha1 :
113   
114        - PYKOTALIMITBY environment variable is now exported too.
115

120        - Improved documentation
121       
122    - 1.18beta2 :
123     
124        - Fix for raw jobs with cupspykota
125       
126    - 1.18beta :
127   
128        - Small fix for new waitprinter.sh script
129       
130        - Better tracebacks on error conditions
131       
132        - Improved translations
133       
134        - Improved documentation
135       
136    - 1.18alpha15 :

156         
157        - The pykota filter doesn't check last user's quota
158          anymore when delayed hardware accounting is used :
159          this will be done anyway the next time the last
160          user will print again. This saves some database
161          queries which are unneeded.
162       
163    - 1.18alpha12 :
164   
165        - Pre and Post hooks to external commands with many
166          many environment variables available are useable
167          from the cupspykota backend.

201          to specify the domain to send mail to when user
202          email address is not set in PyKota database.

215   
216        - Applied some of the modifications suggested by
217          Peter Hawkins, for better Debian integration.
218          Most notably cupspykota, pykota, and the shell
219          scripts are now installed into /usr/share/pykota
220          instead of into /usr/bin
221          BEWARE : double check that your symbolic link
222          to cupspykota is correct, and that your pykota.conf
223          file use correct path for the shell scripts like
224          waitprinter.sh and al.

357           
358            PYKOTAUSERNAME => user who is printing
359            PYKOTAPRINTERNAME => printer on which the job is being sent
360            PYKOTATITLE => Job's title
361            PYKOTAFILENAME => Job's filename
362            PYKOTACOPIES => number of copies asked

384    - 1.16alpha14 :
385   
386        - Now printing on a printer not defined in the Quota Storage,
387          results in the job being cancelled or stopped, depending
388          on the printing system.
389         
390    - 1.16alpha13 :
391   
392        - Small bugfix wrt Python v2.1
393       
394        - If username is an empty string, user root is assumed.
395       
396        - 'postgresql' is not recognized anymore as a storage backend,
397          you have to use 'pgstorage' instead. 'postgresql' used to
398          be supported for compatibility with very old PyKota versions,
399          this is not the case anymore.
400         
401    - 1.16alpha12 :
402   
403        - Job price added to job history, to keep accounting correct
404          if a printer price per page or per job is modified and the
405          history is not reset : the history would have given a false
406          amount of money charged before the printer's prices were
407          modified, this addition solves the problem.
408         
409    - 1.16alpha11 :
410   
411        - Some preliminary modifications to the database structure for
412          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
413          database is now provided. LDAP attributes now support
414          eq, pres and sub indexes.

417          number of copies, filename, title and print options.
418         
419    - 1.16alpha10 :
420       
421        - Some modifications done to external policy handling.
422          See sample configuration file for details.
423   
424        - Spanish translation added.
425       
426    - 1.16alpha9 :
427   
428        - mailto can be set to external(...) to warn users above
429          quota with any command of your choice (e.g. linpopup).
430          Several parameters are available, see sample configuration
431          file for details.
432         
433    - 1.16alpha8 :
434   
435        - Now cupspykota transmits SIGTERMS to the original 
436          backend when the user deletes a job being processed.
437         
438        - The documentation is now licensed under the terms of the
439          GNU GPL too.
440         
441    - 1.16alpha7 :
442   
443        - The CUPS backend is now fully functionnal (it seems).
444       
445        - From now on, the use of the pykota filter with CUPS
446          is deprecated. The pykota filter still has to be
447          used with LPRng though.
448       
449    - 1.16alpha6 :
450   
451        - Bug fixed : when edpykota was used to add a printer
452          with no user or group name, a bad user/group name "*" was
453          added to the database.
454         
455    - 1.16alpha5 :
456   
457        - New CUPS backend supports device enumeration !
458          This means that NO manual CUPS configuration has to
459          be done. All can now be done from CUPS web interface.
460       
461    - 1.16alpha4 :
462

490        - External policy can be used to auto-add unknown users
491          and any other interesting things you may want to do.
492          WARNING : You can't auto-add printers for now.
493          They have to be created manually before.
494          Look at sample configuration file for examples.
495         
496    - 1.15alpha8 :
497   
498        - Job history can be disabled if needed.
499          This feature may be useful for people who use the LDAP
500          backend and don't want their LDAP tree to grow out of
501          control.
502       
503    - 1.15alpha7 :

523          REMOTE_USER environment variable is set. This allows
524          people to protect its use with .htaccess files.
525          When unprotected, or if REMOTE_USER is 'root', then
526          unrestricted access is granted.
527          NB : REMOTE_USER is automatically set by the web server
528          (e.g. Apache) when a page with restricted access is viewed.
529         
530    - 1.15alpha2 :
531   
532        - Better detection of LPRng.
533       
534        - Outputs a warning if printing system is unknown.
535       
536    - 1.15alpha1 :
537   
538        - Bug fix in SQL code.
539       
540    - 1.14 :
541   
542        - The PostgreSQL database connection is now always closed before
543          exit. The LDAP database connection too, but it didn't suffer
544          from the problem anyway, AFAICT.
545       
546    - 1.14beta2 :
547   
548        - An LDAP-specific configuration field was introduced, usermail.
549          Use it to specify which LDAP attribute contains a valid email
550          address for the user. See sample configuration file for
551          details.
552       
553    - 1.14beta :
554   
555        - Two new LDAP-specific configuration fields were introduced,
556          newuser and newgroup. Use them to specify if you want to add
557          quota information to existing entries or elsewhere.
558          See sample configuration file for details.
559         
560    - 1.14alpha9 :
561   
562        - Documentation improved.
563       
564        - pykotme now also prints the user's account balance value
565          if the user is registered in the Quota Storage and his
566          limiting factor is "balance".
567         
568    - 1.14alpha8 :
569   
570        - bin/waitprinter.sh is now included to wait for
571          SNMP enabled printers to be idle again before
572          asking for their internal page counter.
573          See sample configuration file for details.
574         
575    - 1.14alpha7 :
576   
577        - edpykota now doesn't check if the user/group is above
578          quota. The check is only done at print time. This
579          prevents the sending of email messages when creating
580          user quotas if quota is already reached at creation
581          time.
582         
583    - 1.14alpha6 :
584   
585        - Configuration file split and moved to /etc/pykota/pykota.conf
586          and /etc/pykota/pykotadmin.conf to prevent simple users to
587          have Read/Write access to the Quota Database.
588          Don't forget to :
589         
590                $ chmod 640 /etc/pykota/pykotadmin.conf
591               
592        - storageuser and storageuserpw configuration fields reintroduced
593          for the same reason.
594         
595        - Code cleaning for future implementation of email addresses
596          support in the PostgreSQL and LDAP backends.
597         
598    - 1.14alpha5 :
599       
600        - Big bug fixed when changing the prices for a printer
601       
602    - 1.14alpha4 :
603   
604        - When adding an user, the user itself and its account balance
605          are now added in the same LDAP entry. Before they were added
606          as two different LDAP entries.
607         
608    - 1.14alpha3 :
609   
610        - Email field added to PostgreSQL database. An upgrade script
611          is included in initscripts/postgresql.
612       
613    - 1.14alpha2 :
614   
615        - Typo fixed when using the --prototype option to edpykota
616       
617    - 1.14alpha1 :
618   
619        - Poor man's treshold included : users with a low account
620          balance (below 1.0 by default, configurable) are sent
621          a warning message.
622         
623        - All warning messages to users are now configurable. 
624          NB : Warning messages to the administrator are not.
625       
626    - 1.13 :
627   
628        - Some small fixes wrt group handling.
629       
630        - The whole module code was passed through PyChecker and
631          several small code inconsistencies were fixed,
632          as well as a bug in the groups code.
633         
634    - 1.13alpha1 :
635   
636        - Bug fix wrt LDAP.
637       
638    - 1.12 :
639   
640        - More complete test added in edpykota.
641       
642    - 1.12alpha2 :
643   
644        - The previous bug fix was incomplete. This is corrected.
645       
646    - 1.12alpha1 :
647   
648        - Small bug fix.
649       
650    - 1.11 :
651   
652        - Now includes the pykotme command line tool, to produce
653          printing quotes for users.
654         
655    - 1.10 :
656   
657        - Bug fixed wrt quota reports when print limiting is by
658          account balance.
659         
660    - 1.09 :
661   
662        - Translations finalized.
663       
664        - Manpages updated.
665       
666        - Installation documentation improved wrt LDAP support.
667       
668    - 1.09beta2 :
669   
670        - The CGI script for quota reports works again, and
671          is much more powerful.
672       
673    - 1.09beta :
674   
675        - edpykota finalized
676       
677    - 1.09alpha2 :
678   
679        - LDAP schema modified a bit. Please upgrade.
680       
681        - LDAP backend works !
682       
683        - repykota and warnpykota allow the root user to pass
684          users or groups names on the command line. Users
685          and groups names may contain wildcards.
686         
687        - repykota and warnpykota only reports or warns the
688          current user when launched by non-root users.
689         
690        - Minor bug fixes. 
691   
692    - 1.09alpha1 :
693   
694        - More work on LDAP storage backend. Many options
695          were added to /etc/pykota.conf to give some
696          hints to the LDAP storage backend.
697         
698        - Severe database access optimizations were done by
699          rewriting most of the Quota Storage backends drivers.
700     
701    - 1.08 :
702   
703        - Major bug fix wrt LPRng support for remote jobs.
704       
705        - Major bug fix wrt increase/decrease account balances.
706       
707    - 1.08alpha8 :
708   
709        - Code refactoring.
710       
711        - A single user/password pair is used to connect
712          to the database backend. The storageuser configuration
713          field, and its associated passwords storageuserpw, are
714          not used anymore.
715         
716        - You can now set PyKota in debug mode, see sample configuration 
717          file for details.
718          WARNING : only Quota Storage backend queries are logged in
719          debug mode, for now.
720       
721    - 1.08alpha7 :
722   
723        - Very latest LDAP schema.
724       
725        - Code enhancement wrt easy pluggability of PyKota attributes
726          and object classes into an existing LDAP directory.
727       
728    - 1.08alpha6 :
729   
730        - Minor bug corrections
731       
732        - More work on LDAP : new schema
733       
734    - 1.08alpha5 :
735   
736        - More good work on LDAP storage.
737          repykota now works reasonably well with the sample LDAP directory.
738       
739    - 1.08alpha4 :
740   
741        - LDAP schema included.
742          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
743          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
744          MAY CHANGE IN THE FUTURE. PLEASE TELL US
745          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
746          MAILING LIST.
747         
748    - 1.08alpha3 :
749   
750        - External accounting methods were partly rewritten :
751         
752          - No more "broken pipe" should happen.
753         
754          - They now take care of the number of copies
755            This may be unneeded though, if the postscript
756            file already does this, because this would
757            overcharge users (number of copies counted
758            two times). NEEDS MORE TESTING.
759           
760          - The sample configuration file now contains 
761            an external accounting method example which should
762            work with all DSC compliant Postscript files.
763           
764        - Some small bugs were fixed.   
765       
766    - 1.08alpha2 :
767   
768        - Now works with net-snmp v5.0 and above.
769          It already worked, but the sample configuration
770          file didn't contain appropriate values...
771       
772    - 1.07 : Release of the Shame !
773   
774        - The external accounting methods driver was left out of
775          the CVS tree. Nobody could use it since it wasn't included !
776         
777    - 1.06 :
778   
779        - Severe bug fixed : if you had a printer in
780          power saving state which couldn't answer immediately,
781          a bug was triggered.
782          It was caused by a bad copy/paste which
783          forgot to import a Python module at run time.
784         
785    - 1.05 :
786   
787        - External accounters are finally available !
788          This means that you can plug any page accounting
789          method you like by setting the appropriate
790          'accounter' field in /etc/pykota.conf
791          See the sample conf/pykota.conf.sample to
792          learn how to do.
793         
794          NB : Both 'external' and 'stupid' accounting methods
795               account a job size just before *this* job is
796               sent to the printer.
797               The original 'querying' method accounts a job
798               size just before *the next* job is sent to
799               the printer.
800       
801    - 1.05alpha3 :
802   
803        - A 'stupid' and unreliable accounting method was
804          implemented to serve as an example on how to
805          do this sort of things. This method only counts
806          the 'showpage' statements in the input data.
807          See sample configuration file for details.
808          Pluggable accounting methods work, but I advise
809          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
810          It is not reliable enough to be used.
811          Use the 'querying' accounting method instead.
812         
813    - 1.05alpha2 :
814   
815        - Pluggable accounting methods.
816       
817        - Better error handling.
818       
819    - 1.05alpha1 :
820   
821        - SECURITY file added to help improve PyKota's security.
822       
823        - Extracting the printer's internal page counter is now
824          tried several times, waiting several seconds between
825          two tries. This lets the time to warm up for some printers
826          which don't answer when they are sleeping (my Apple
827          LaserWriter 16/600 PS is in this case, maybe others too)
828         
829        - Small display bug fixed in repykota
830         
831    - 1.04 :
832   
833        - Default print policy for users/groups unknown from
834          the print quota system is now DENY instead of ALLOW,
835          since ALLOW can generate inaccurate results
836          (incorrect job sizes charged to the wrong persons)
837         
838        - LPRng support works !
839       
840        - A bug was introduced some time ago wrt printers' default
841          policy for unknown users. It is now corrected.
842       
843        - repykota now displays prices per job and per page for each
844          printer, if they are defined.
845         
846        - Minor display bug fixed in repykota.
847       
848        - Problem when running repykota with an empty database was fixed.
849       
850    - 1.03 :
851   
852        - Upgrade script included for earlier versions.
853          Please look inside the initscripts subdirectory.
854          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
855         
856        - repykota now reports account balances too.
857       
858        - PyKota now has a nice logo, see the logos
859          subdirectory.
860       
861        - Manual pages were finally updated.
862       
863        - Group quotas seem to work now !
864       
865        - The new database schema allows to keep an history of all
866          jobs as well as charge users per page and/or per job,
867          and track users' account balance.
868         
869        - edpykota now accepts much more command line options to 
870          use the new functionnalities. See edpykota --help for
871          details.
872         
873        - The installation script now allows to install the sample
874          configuration file during first installation.
875         
876        - More group quota code works, but still not finished. 
877       
878        - The CGI script displays a link to PyKota's website.
879       
880        - The job history is now kept, this will allow per-period
881          reports in the future.
882         
883        - After having modified the quota for an user with edpykota,
884          a quota check is done to eventually warn the user/admin about
885          a quota which is too low to print.
886         
887        - A workaround is provided for HP Printers : their internal
888          page counter is only saved to NVRAM in a 10 increment, so
889          if you switch them off and then on, the reported page counter
890          may be lower than the real number of pages printed.
891          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
892          We unconditionnally set the last job's page count to
893          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
894          in this case.
895          For a more accurate accounting, never switch your HP printers
896          off.
897         
898        - A fix is provided for printers which only have a volatile 
899          page counter (reset to 0 every time you switch the printer on)
900          This should allow PyKota to work reasonably fine with HP Laserjet
901          4L/5L/6L, not perfect, but better than nothing.
902          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
903          For a more accurate accounting, never switch your HP printers
904          off. This is untested, please report any problem.
905         
906        - A bug was fixed when edpykota --add was used with users who already
907          had a quota on the specified printer.
908         
909        - A small display bug in repykota was introduced in preliminary
910          1.03 versions, and fixed later on.
911         
912        - Some minor bugs which happened in rare situations were fixed.
913       
914        - Support for AppleTalk printers was added, see sample configuration
915          file for details.
916         
917        - Users and group printing can now be controlled (limited) either by 
918          print quota or by account balance.
919       
920    - 1.02 :
921   
922        - The installation script now checks for software availability
923          and in case a software is missing asks the user if he
924          wants to continue with the installation or abort it.
925         
926        - The configuration file pykota.conf is now expected to be
927          found in /etc instead of in /etc/cups
928          The installation script prompts the user to see if he
929          wants to move an old configuration file to the new location
930          if needed.
931         
932        - Improved documentation.
933       
934        - You can now set the tcp/ip port on which the Quota Storage
935          Server is listening, see sample configuration file for details.
936       
937        - Better general error handling.
938       
939        - Upgrade script for pre 1.01 PostgreSQL database schema is now
940          included as well.
941       
942    - 1.01 :
943   
944        - The configuration file now accepts an option   
945          to choose the recipient(s) of the email messages :
946         
947            - DevNull means no one will receive them.
948            - User means only the user will receive them.
949            - Admin means only the admin will receive them.
950            - Both means the User and the Admin will receive them.
951           
952        - The configuration file now uses hard-coded default values
953          when an option is not set. See sample configuration file
954          for details.
955         
956        - Manual pages are included since 1.00, but I forgot to   
957          add this information to this file.
958         
959        - Redistribution terms for the official package have 
960          softened and are now fully GPL compatible :
961          unrestricted modification is now allowed even for
962          the version number.
963         
964    - 1.00 :
965   
966        - edpykota now accepts a --noquota option. This
967          disable quota checking while still doing page
968          accounting. This is really useful for people
969          who don't want to limit their users but want
970          to know how much pages they print.
971         
972        - Some untested scripts were added to retrieve
973          the life time page counter of non-SNMP printers.
974         
975        - Every directory now has a specific README file. 
976       
977    - 0.99 :
978   
979        - Under some circumstances while the user wasn't allowed
980          to print, he didn't receive any email message. It is
981          now fixed.
982         
983        - When an user wasn't allowed to print, the quota for
984          the previous user wasn't updated. This is now fixed.
985         
986    - 0.98 :
987   
988        - Correctly handle the case where the printer is switched off.
989       
990        - Small bug wrt syslog fixed.
991       
992    - 0.97 :
993   
994        - edpykota accepts wildcards on its command line for users/groups too
995          if the --add option is not set, e.g. :
996         
997              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
998             
999        - If no user name is passed at all, then a default wildcard of "*"
1000          which means apply the command on ALL users for this printer is used.
1001         
1002        - Small bug fixes.
1003       
1004    - 0.96 :
1005
1006        - Options requester, policy, admin, adminmail and gracedelay can now
1007          be set either globally or per printer. The printer option has
1008          priority if both are defined.
1009
1010        - More powerful configuration parser.
1011
