22PyKota NEWS :
23
24    - 1.19alpha6 :
25   
26        - pykotme now uses pkpgcounter to compute the size of the
27          job. This modification adds PCL5 and soon PCLXL (PCL6)
28          support. You can now get quotes for PCL in addition to
29          PostScript.
30         
31        - pkpgcounter now includes first try at PCLXL parser. 
32          It is currently disabled until it's finished.
33         
34    - 1.19alpha5 :
35   
36        - cupspykota polling loop fix for MacOSX (at least)
37       
38        - logging subsystem now logs PID too, to ease diagnosing
39          problems under heavy load.
40         
41        - pkpgcounter enhancements.
42       
43        - pkprinters --skipexisting now tells pkprinters to not
44          modify existing printers when --add is used.
45          pkprinters logs a warning message whenever --add is
46          used and a printer already exists.
47         
48        - LDAP schema now allows accented chars in pykotaFileName
49          and pykotaTitle attributes.
50       
51    - 1.19alpha4 :
52   
53        - a bad copy&paste prevented pkpgcounter to work at all, this
54          is now fixed.
55         
56        - improved PCL support in pkpgcounter, with the use of
57          HP PCL/PJL Reference Set
58          PCL5 Printer Language Technical Quick Reference Guide
59       
60        - pkpgcounter now uses mmap to speed things up : duration
61          is halved with the sample 87 pages PCL document I use for
62          testing.
63         
64    - 1.19alpha3 :
65   
66        - pkprinters now accepts the --list command line argument
67          to list informations about printers.
68         
69    - 1.19alpha2 :
70   
71        - pkpgcounter is now included as a smart external
72          accounter which can handle both PostScript and PCL.
73         
74    - 1.19alpha1 :
75   
76        - PYKOTALIMITBY environment variable is now exported too.
77       
78        - Inclusion of Michele Baldessari's work on autotools.
79       
80    - 1.18 :
81   
82        - Improved documentation
83       
84    - 1.18beta2 :
85     
86        - Fix for raw jobs with cupspykota
87       
88    - 1.18beta :
89   
90        - Small fix for new waitprinter.sh script
91       
92        - Better tracebacks on error conditions
93       
94        - Improved translations
95       
96        - Improved documentation
97       
98    - 1.18alpha15 :
99
100        - waitprinter.sh replaced by a new and possibly faster
101          and more powerful one.
102   
103        - Names can now begin with a digit.
104       
105        - Stability improvement for quotas set on printers groups.
106       
107    - 1.18alpha14 :
108   
109        - Catches more (all ?) problems with SMTP servers instead
110          of breaking.

113       
114    - 1.18alpha13 :

116        - Pre and Post hooks are now available in the pykota
117          filter as well.
118         
119        - The pykota filter doesn't check last user's quota
120          anymore when delayed hardware accounting is used :
121          this will be done anyway the next time the last
122          user will print again. This saves some database
123          queries which are unneeded.
124       
125    - 1.18alpha12 :
126   
127        - Pre and Post hooks to external commands with many
128          many environment variables available are useable
129          from the cupspykota backend.
130          See sample configuration file for details and help.
131

161       
162        - New configuration directive added : maildomain
163          to specify the domain to send mail to when user
164          email address is not set in PyKota database.

177   
178        - Applied some of the modifications suggested by
179          Peter Hawkins, for better Debian integration.
180          Most notably cupspykota, pykota, and the shell
181          scripts are now installed into /usr/share/pykota
182          instead of into /usr/bin
183          BEWARE : double check that your symbolic link
184          to cupspykota is correct, and that your pykota.conf
185          file use correct path for the shell scripts like
186          waitprinter.sh and al.

252       
253          SUM((NbPages * PricePerPage) + PricePerJob)
254         
255          For current printer and all the printers groups it is
256          a member of, if any.
257         
258          This may be difficult to grasp, but offers unprecedented
259          flexibility.

289       
290        - Printer groups are now cached too.
291       
292    - 1.16alpha20 :
293   
294        - Fixed several small bugs with the help of PyChecker.
295

299       
300    - 1.16alpha18 :

314        - mailandpopup.sh shell script added. See sample configuration file
315          for details.
316       
317        - Several environment variables are now exported when executing
318          external commands (accounters, requesters, mailers) :
319           
320            PYKOTAUSERNAME => user who is printing
321            PYKOTAPRINTERNAME => printer on which the job is being sent
322            PYKOTATITLE => Job's title
323            PYKOTAFILENAME => Job's filename
324            PYKOTACOPIES => number of copies asked
325            PYKOTAOPTIONS => print command options (-o with CUPS)
326         
327    - 1.16alpha17 :
328   
329        - Added portugues translation.
330       
331        - Major code refactoring in accounters.

335        - Code refactoring, and addition of a real HTML reporter, to
336          have nice looking and useful web based reports (in the future).
337       
338        - Added utolower configuration option to convert all usernames
339          to lowercase during printing.
340         
341    - 1.15alpha15 :
342   
343        - Now includes the papwaitprinter.sh shell script to wait for
344          AppleTalk enabled printers.
345         
346    - 1.16alpha14 :
347   
348        - Now printing on a printer not defined in the Quota Storage,
349          results in the job being cancelled or stopped, depending
350          on the printing system.
351         
352    - 1.16alpha13 :
353   
354        - Small bugfix wrt Python v2.1
355       
356        - If username is an empty string, user root is assumed.
357       
358        - 'postgresql' is not recognized anymore as a storage backend,
359          you have to use 'pgstorage' instead. 'postgresql' used to
360          be supported for compatibility with very old PyKota versions,
361          this is not the case anymore.
362         
363    - 1.16alpha12 :
364   
365        - Job price added to job history, to keep accounting correct
366          if a printer price per page or per job is modified and the
367          history is not reset : the history would have given a false
368          amount of money charged before the printer's prices were
369          modified, this addition solves the problem.
370         
371    - 1.16alpha11 :
372   
373        - Some preliminary modifications to the database structure for
374          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
375          database is now provided. LDAP attributes now support
376          eq, pres and sub indexes.
377         
378        - Job history now contains additional informations : 
379          number of copies, filename, title and print options.
380         
381    - 1.16alpha10 :
382       
383        - Some modifications done to external policy handling.
384          See sample configuration file for details.
385   
386        - Spanish translation added.
387       
388    - 1.16alpha9 :
389   
390        - mailto can be set to external(...) to warn users above
391          quota with any command of your choice (e.g. linpopup).
392          Several parameters are available, see sample configuration
393          file for details.
394         
395    - 1.16alpha8 :
396   
397        - Now cupspykota transmits SIGTERMS to the original 
398          backend when the user deletes a job being processed.
399         
400        - The documentation is now licensed under the terms of the
401          GNU GPL too.
402         
403    - 1.16alpha7 :
404   
405        - The CUPS backend is now fully functionnal (it seems).
406       
407        - From now on, the use of the pykota filter with CUPS
408          is deprecated. The pykota filter still has to be
409          used with LPRng though.
410       
411    - 1.16alpha6 :
412   
413        - Bug fixed : when edpykota was used to add a printer
414          with no user or group name, a bad user/group name "*" was
415          added to the database.
416         
417    - 1.16alpha5 :
418   
419        - New CUPS backend supports device enumeration !
420          This means that NO manual CUPS configuration has to
421          be done. All can now be done from CUPS web interface.
422       
423    - 1.16alpha4 :
424   
425        - New CUPS backend added.
426       
427    - 1.16alpha3 :
428       
429        - Minimal FAQ document added.
430       
431    - 1.16alpha2 :
432   
433        - CGI script now partially supports browser's language preference
434       
435    - 1.16alpha1 :
436   
437        - Ensures that the LDAP connection is really closed at end.
438       
439        - More complete error messages in case of LDAP operation failure.

448          names or wildcards, separated with commas.
449         
450    - 1.15alpha9 :
451   
452        - External policy can be used to auto-add unknown users
453          and any other interesting things you may want to do.
454          WARNING : You can't auto-add printers for now.
455          They have to be created manually before.
456          Look at sample configuration file for examples.
457         
458    - 1.15alpha8 :
459   
460        - Job history can be disabled if needed.
461          This feature may be useful for people who use the LDAP
462          backend and don't want their LDAP tree to grow out of
463          control.
464       
465    - 1.15alpha7 :
466   
467        - More work done on caching wrt groups.
468

480          modification.
481         
482    - 1.15alpha3 :
483   
484        - CGI script now tries to restrict view when the
485          REMOTE_USER environment variable is set. This allows
486          people to protect its use with .htaccess files.
487          When unprotected, or if REMOTE_USER is 'root', then
488          unrestricted access is granted.
489          NB : REMOTE_USER is automatically set by the web server
490          (e.g. Apache) when a page with restricted access is viewed.
491         
492    - 1.15alpha2 :
493   
494        - Better detection of LPRng.
495

501       
502    - 1.14 :

504        - The PostgreSQL database connection is now always closed before
505          exit. The LDAP database connection too, but it didn't suffer
506          from the problem anyway, AFAICT.
507       
508    - 1.14beta2 :
509   
510        - An LDAP-specific configuration field was introduced, usermail.
511          Use it to specify which LDAP attribute contains a valid email
512          address for the user. See sample configuration file for
513          details.
514       
515    - 1.14beta :
516   
517        - Two new LDAP-specific configuration fields were introduced,
518          newuser and newgroup. Use them to specify if you want to add
519          quota information to existing entries or elsewhere.
520          See sample configuration file for details.
521         
522    - 1.14alpha9 :
523   
524        - Documentation improved.
525       
526        - pykotme now also prints the user's account balance value
527          if the user is registered in the Quota Storage and his
528          limiting factor is "balance".
529         
530    - 1.14alpha8 :
531   
532        - bin/waitprinter.sh is now included to wait for
533          SNMP enabled printers to be idle again before
534          asking for their internal page counter.
535          See sample configuration file for details.
536         
537    - 1.14alpha7 :
538   
539        - edpykota now doesn't check if the user/group is above
540          quota. The check is only done at print time. This
541          prevents the sending of email messages when creating
542          user quotas if quota is already reached at creation
543          time.
544         
545    - 1.14alpha6 :
546   
547        - Configuration file split and moved to /etc/pykota/pykota.conf
548          and /etc/pykota/pykotadmin.conf to prevent simple users to
549          have Read/Write access to the Quota Database.
550          Don't forget to :
551         
552                $ chmod 640 /etc/pykota/pykotadmin.conf
553               
554        - storageuser and storageuserpw configuration fields reintroduced
555          for the same reason.
556         
557        - Code cleaning for future implementation of email addresses
558          support in the PostgreSQL and LDAP backends.
559         
560    - 1.14alpha5 :
561       
562        - Big bug fixed when changing the prices for a printer
563       
564    - 1.14alpha4 :
565   
566        - When adding an user, the user itself and its account balance
567          are now added in the same LDAP entry. Before they were added
568          as two different LDAP entries.
569         
570    - 1.14alpha3 :
571   
572        - Email field added to PostgreSQL database. An upgrade script
573          is included in initscripts/postgresql.
574       
575    - 1.14alpha2 :
576   
577        - Typo fixed when using the --prototype option to edpykota
578       
579    - 1.14alpha1 :
580   
581        - Poor man's treshold included : users with a low account
582          balance (below 1.0 by default, configurable) are sent
583          a warning message.
584         
585        - All warning messages to users are now configurable. 
586          NB : Warning messages to the administrator are not.
587       
588    - 1.13 :
589   
590        - Some small fixes wrt group handling.
591       
592        - The whole module code was passed through PyChecker and
593          several small code inconsistencies were fixed,
594          as well as a bug in the groups code.
595         
596    - 1.13alpha1 :
597   
598        - Bug fix wrt LDAP.
599       
600    - 1.12 :
601   
602        - More complete test added in edpykota.
603       
604    - 1.12alpha2 :
605   
606        - The previous bug fix was incomplete. This is corrected.
607       
608    - 1.12alpha1 :
609   
610        - Small bug fix.
611       
612    - 1.11 :
613   
614        - Now includes the pykotme command line tool, to produce
615          printing quotes for users.
616         
617    - 1.10 :
618   
619        - Bug fixed wrt quota reports when print limiting is by
620          account balance.
621         
622    - 1.09 :
623   
624        - Translations finalized.
625       
626        - Manpages updated.
627       
628        - Installation documentation improved wrt LDAP support.
629       
630    - 1.09beta2 :
631   
632        - The CGI script for quota reports works again, and
633          is much more powerful.
634       
635    - 1.09beta :
636   
637        - edpykota finalized
638       
639    - 1.09alpha2 :
640   
641        - LDAP schema modified a bit. Please upgrade.
642       
643        - LDAP backend works !
644       
645        - repykota and warnpykota allow the root user to pass
646          users or groups names on the command line. Users
647          and groups names may contain wildcards.
648         
649        - repykota and warnpykota only reports or warns the
650          current user when launched by non-root users.
651         
652        - Minor bug fixes. 
653   
654    - 1.09alpha1 :
655   
656        - More work on LDAP storage backend. Many options
657          were added to /etc/pykota.conf to give some
658          hints to the LDAP storage backend.
659         
660        - Severe database access optimizations were done by
661          rewriting most of the Quota Storage backends drivers.
662     
663    - 1.08 :
664   
665        - Major bug fix wrt LPRng support for remote jobs.
666       
667        - Major bug fix wrt increase/decrease account balances.
668       
669    - 1.08alpha8 :
670   
671        - Code refactoring.
672       
673        - A single user/password pair is used to connect
674          to the database backend. The storageuser configuration
675          field, and its associated passwords storageuserpw, are
676          not used anymore.
677         
678        - You can now set PyKota in debug mode, see sample configuration 
679          file for details.
680          WARNING : only Quota Storage backend queries are logged in
681          debug mode, for now.
682       
683    - 1.08alpha7 :
684   
685        - Very latest LDAP schema.
686       
687        - Code enhancement wrt easy pluggability of PyKota attributes
688          and object classes into an existing LDAP directory.
689       
690    - 1.08alpha6 :
691   
692        - Minor bug corrections
693       
694        - More work on LDAP : new schema
695       
696    - 1.08alpha5 :
697   
698        - More good work on LDAP storage.
699          repykota now works reasonably well with the sample LDAP directory.
700       
701    - 1.08alpha4 :
702   
703        - LDAP schema included.
704          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
705          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
706          MAY CHANGE IN THE FUTURE. PLEASE TELL US
707          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
708          MAILING LIST.
709         
710    - 1.08alpha3 :
711   
712        - External accounting methods were partly rewritten :
713         
714          - No more "broken pipe" should happen.
715         
716          - They now take care of the number of copies
717            This may be unneeded though, if the postscript
718            file already does this, because this would
719            overcharge users (number of copies counted
720            two times). NEEDS MORE TESTING.
721           
722          - The sample configuration file now contains 
723            an external accounting method example which should
724            work with all DSC compliant Postscript files.
725           
726        - Some small bugs were fixed.   
727       
728    - 1.08alpha2 :
729   
730        - Now works with net-snmp v5.0 and above.
731          It already worked, but the sample configuration
732          file didn't contain appropriate values...
733       
734    - 1.07 : Release of the Shame !
735   
736        - The external accounting methods driver was left out of
737          the CVS tree. Nobody could use it since it wasn't included !
738         
739    - 1.06 :
740   
741        - Severe bug fixed : if you had a printer in
742          power saving state which couldn't answer immediately,
743          a bug was triggered.
744          It was caused by a bad copy/paste which
745          forgot to import a Python module at run time.
746         
747    - 1.05 :
748   
749        - External accounters are finally available !
750          This means that you can plug any page accounting
751          method you like by setting the appropriate
752          'accounter' field in /etc/pykota.conf
753          See the sample conf/pykota.conf.sample to
754          learn how to do.
755         
756          NB : Both 'external' and 'stupid' accounting methods
757               account a job size just before *this* job is
758               sent to the printer.
759               The original 'querying' method accounts a job
760               size just before *the next* job is sent to
761               the printer.
762       
763    - 1.05alpha3 :
764   
765        - A 'stupid' and unreliable accounting method was
766          implemented to serve as an example on how to
767          do this sort of things. This method only counts
768          the 'showpage' statements in the input data.
769          See sample configuration file for details.
770          Pluggable accounting methods work, but I advise
771          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
772          It is not reliable enough to be used.
773          Use the 'querying' accounting method instead.
774         
775    - 1.05alpha2 :
776   
777        - Pluggable accounting methods.
778       
779        - Better error handling.
780       
781    - 1.05alpha1 :
782   
783        - SECURITY file added to help improve PyKota's security.
784       
785        - Extracting the printer's internal page counter is now
786          tried several times, waiting several seconds between
787          two tries. This lets the time to warm up for some printers
788          which don't answer when they are sleeping (my Apple
789          LaserWriter 16/600 PS is in this case, maybe others too)
790         
791        - Small display bug fixed in repykota
792         
793    - 1.04 :
794   
795        - Default print policy for users/groups unknown from
796          the print quota system is now DENY instead of ALLOW,
797          since ALLOW can generate inaccurate results
798          (incorrect job sizes charged to the wrong persons)
799         
800        - LPRng support works !
801       
802        - A bug was introduced some time ago wrt printers' default
803          policy for unknown users. It is now corrected.
804       
805        - repykota now displays prices per job and per page for each
806          printer, if they are defined.
807         
808        - Minor display bug fixed in repykota.
809       
810        - Problem when running repykota with an empty database was fixed.
811       
812    - 1.03 :
813   
814        - Upgrade script included for earlier versions.
815          Please look inside the initscripts subdirectory.
816          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
817         
818        - repykota now reports account balances too.
819       
820        - PyKota now has a nice logo, see the logos
821          subdirectory.
822       
823        - Manual pages were finally updated.
824       
825        - Group quotas seem to work now !
826       
827        - The new database schema allows to keep an history of all
828          jobs as well as charge users per page and/or per job,
829          and track users' account balance.
830         
831        - edpykota now accepts much more command line options to 
832          use the new functionnalities. See edpykota --help for
833          details.
834         
835        - The installation script now allows to install the sample
836          configuration file during first installation.
837         
838        - More group quota code works, but still not finished. 
839       
840        - The CGI script displays a link to PyKota's website.
841       
842        - The job history is now kept, this will allow per-period
843          reports in the future.
844         
845        - After having modified the quota for an user with edpykota,
846          a quota check is done to eventually warn the user/admin about
847          a quota which is too low to print.
848         
849        - A workaround is provided for HP Printers : their internal
850          page counter is only saved to NVRAM in a 10 increment, so
851          if you switch them off and then on, the reported page counter
852          may be lower than the real number of pages printed.
853          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
854          We unconditionnally set the last job's page count to
855          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
856          in this case.
857          For a more accurate accounting, never switch your HP printers
858          off.
859         
860        - A fix is provided for printers which only have a volatile 
861          page counter (reset to 0 every time you switch the printer on)
862          This should allow PyKota to work reasonably fine with HP Laserjet
863          4L/5L/6L, not perfect, but better than nothing.
864          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
865          For a more accurate accounting, never switch your HP printers
866          off. This is untested, please report any problem.
867         
868        - A bug was fixed when edpykota --add was used with users who already
869          had a quota on the specified printer.
870         
871        - A small display bug in repykota was introduced in preliminary
872          1.03 versions, and fixed later on.
873         
874        - Some minor bugs which happened in rare situations were fixed.
875       
876        - Support for AppleTalk printers was added, see sample configuration
877          file for details.
878         
879        - Users and group printing can now be controlled (limited) either by 
880          print quota or by account balance.
881       
882    - 1.02 :
883   
884        - The installation script now checks for software availability
885          and in case a software is missing asks the user if he
886          wants to continue with the installation or abort it.
887         
888        - The configuration file pykota.conf is now expected to be
889          found in /etc instead of in /etc/cups
890          The installation script prompts the user to see if he
891          wants to move an old configuration file to the new location
892          if needed.
893         
894        - Improved documentation.
895       
896        - You can now set the tcp/ip port on which the Quota Storage
897          Server is listening, see sample configuration file for details.
898       
899        - Better general error handling.
900       
901        - Upgrade script for pre 1.01 PostgreSQL database schema is now
902          included as well.
903       
904    - 1.01 :
905   
906        - The configuration file now accepts an option   
907          to choose the recipient(s) of the email messages :
908         
909            - DevNull means no one will receive them.
910            - User means only the user will receive them.
911            - Admin means only the admin will receive them.
912            - Both means the User and the Admin will receive them.
913           
914        - The configuration file now uses hard-coded default values
915          when an option is not set. See sample configuration file
916          for details.
917         
918        - Manual pages are included since 1.00, but I forgot to   
919          add this information to this file.
920         
921        - Redistribution terms for the official package have 
922          softened and are now fully GPL compatible :
923          unrestricted modification is now allowed even for
924          the version number.
925         
926    - 1.00 :
927   
928        - edpykota now accepts a --noquota option. This
929          disable quota checking while still doing page
930          accounting. This is really useful for people
931          who don't want to limit their users but want
932          to know how much pages they print.
933         
934        - Some untested scripts were added to retrieve
935          the life time page counter of non-SNMP printers.
936         
937        - Every directory now has a specific README file. 
938       
939    - 0.99 :
940   
941        - Under some circumstances while the user wasn't allowed
942          to print, he didn't receive any email message. It is
943          now fixed.
944         
945        - When an user wasn't allowed to print, the quota for
946          the previous user wasn't updated. This is now fixed.
947         
948    - 0.98 :
949   
950        - Correctly handle the case where the printer is switched off.
951       
952        - Small bug wrt syslog fixed.
953       
954    - 0.97 :
955   
956        - edpykota accepts wildcards on its command line for users/groups too
957          if the --add option is not set, e.g. :
958         
959              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
960             
961        - If no user name is passed at all, then a default wildcard of "*"
962          which means apply the command on ALL users for this printer is used.
963         
964        - Small bug fixes.
965       
966    - 0.96 :
967
968        - Options requester, policy, admin, adminmail and gracedelay can now
969          be set either globally or per printer. The printer option has
970          priority if both are defined.
971
972        - More powerful configuration parser.
973       
974        - If all options are defined globally, there's no need to
975          define a section for each printer in the configuration
976          file anymore. Just define a [global] section and it's ok.
977
978    - 0.95 :
979
980        - External requesters for printers finally added.
981
982        - Full internationalization (english and french are supported)
983 
984        - More complete quota usage report
985
986        - CGI script to access to the quota usage report
987
988        - Several bugs fixed.
989
990
991    - 0.9 :
992
993        - First public version
