22PyKota NEWS :
23       
24    - 1.22alpha8 :
25   
26        - Fixed the dump in CUPS' page_log format which didn't
27          dump the oldest entry.
28         
29        - The data dumper now accepts billingcode= and hostname= as
30          filters when dumping the job history.
31         
32        - The job billing code if present is now saved into the database,
33          and exported to subprocesses as the PYKOTAJOBBILLING environment
34          variable.
35         
36        - Ctrl+C now makes PyKota commands exit without a traceback.
37       
38        - Fixed an i18n problem with Python 2.1
39       
40    - 1.22alpha7 :
41   
42        - Fixed some problems with the retrieval of the history from LDAP.
43       
44    - 1.22alpha6 :
45   
46        - Early errors now produce meaningful error messages (finally !)
47       
48    - 1.22alpha5 :
49       
50        - SNMP and PJL improvements with regard to PowerSave / StandBy.
51       
52    - 1.22alpha4 :
53   
54        - Fixed charset problem under MacOSX.
55       
56        - Allows pkbanner to accept more info to display on its
57          command line.
58         
59    - 1.22alpha3 :
60   
61        - Fixes some case related problems with some LDAP backends.
62       
63        - Fixes some problem for printers which directly go from
64          "idle" to "warmup" and never to "printing" before
65          returning to "idle".
66         
67        - Some permissions settings may have prevented cupspykota
68          from parsing cupsd.conf, this is now fixed.
69         
70    - 1.22alpha2 :
71   
72        - Introduction of the web enabled print quote generator.
73       
74        - Fixed a potential race condition when several backend
75          wrappers were present in CUPS' backend directory.
76         
77        - Fixed dumpykota's output in CUPS' page_log format to better
78          match CUPS format.
79         
80    - 1.22alpha1 :
81   
82        - Import into Subversion.
83       
84    - 1.21 :
85   
86        - Improved documentation.
87       
88        - Improved dependencies checker.
89       
90        - Updated some translation files.
91       
92    - 1.21beta2 :
93   
94        - Fixed an LPRng specific bug.
95       
96        - Several improvements on stability issues with manually modified

102   
103        - Prepared translation files for next release.
104       
105    - 1.21alpha27 :
106   
107        - Allows software() (no arguments) to the software accounting
108          directive. This saves a lot of CPU since the job is not
109          parsed again : the precomputed size is used directly in this
110          case.
111         
112        - epykota's --prototype option now works fine with accounts
113          limited by balance.
114         
115    - 1.21alpha26 :
116   
117        - Fixed the handling of the 'maxdenybanners' directive.
118       
119        - Introduced the 'denyduplicates' directive.
120       
121        - Fixed some database related glitches.
122       
123    - 1.21alpha25 :
124   
125        - The job's size is now always precomputed, even when
126          'enforcement' is not set to 'strict'.
127         
128        - Introduction of the new 'trustjobsize' configuration directive
129          to workaround some problematic printers. See the sample
130          configuration file for details.
131         
132    - 1.21alpha24 :
133   
134        - Big database structure changes. An upgrade script
135          is now included for PostgreSQL. LDAP users may just
136          want to copy the new schema in place.
137         
138        - edpykota now recognizes the -o | --overcharge command line
139          option to set an overcharging or undercharging factor
140          on each print job's cost for a particular user.
141         
142        - repykota's output format has changed an is not limited to 
143          80 characters wide anymore. People who used to parse
144          repykota's output in their own tools are strongly advised
145          to parse dumpykota's output instead.
146         
147        - Introduction of the new 'maxdenybanners' configuration directive
148          to allow up to N (the directive's value) deny banners to be
149          printed even if the print account is forbidden to print.
150         
151        - Better detection of the number of copies in the PostScript parser.
152       
153    - 1.21alpha23 :
154   
155        - Traditional Chinese translation added.
156   
157        - Several fixes and performance improvements with the LDAP backend.
158       
159    - 1.21alpha22 :
160   
161        - edpykota's --delete command line option doesn't consider
162          '*' to be the default argument anymore :-)
163         
164    - 1.21alpha21 :
165   
166        - dumpykota.cgi can now be run as a normal user as opposed to
167          a PyKota administrator. No read access to pykotadmin.conf is
168          necessary anymore. This CGI scripts now honors the REMOTE_USER
169          environment variable just like printquota.cgi does, see
170          the file cgi-bin/README for details.
171          The command line tool dumpykota must still be run by a PyKota
172          administrator.
173         
174        - Fix exception's name error due to a change in recent versions
175          of PygreSQL.   
176         
177    - 1.21alpha20 :
178         
179        - Big bug fix wrt the datelimit field which was never reset.
180         
181    - 1.21alpha19 :
182   
183        - Introduction of the new dumpykota.cgi CGI script, which
184          allows third party tools like phpPrintAnalyzer to be
185          interfaced in real time with PyKota. To use it you
186          may have to change your web server's configuration,
187          please see pykota/cgi-bin/README
188         
189    - 1.21alpha18 :
190   
191        - Now dumpykota can dump the job history into CUPS' page_log
192          format (even when the printing system is LPRng). This allows
193          people to use tools like PrintAnalyzer or phpPrintAnalyzer
194          (two completely different beasts) with PyKota.
195         
196    - 1.21alpha17 :
197     
198        - Fixed field type's name in XML dumps.
199       
200        - Now drops priviledges to user 'pykota' when launched as root
201          (directly or as a CUPS backend), if such an user exists.
202         
203        - Fixed PCL3/4/5 parser for some drivers' output.
204       
205    - 1.21alpha16 :
206   
207        - fixed several recently introduced bugs in LDAP backend code,
208          thanks to Matt Hyclak.
209         
210    - 1.21alpha15 :
211     
212        - Normalized field names between LDAP and PostgreSQL backends
213          in dumpykota's output.
214         
215        - dumpykota filtering capabilities are now supported within
216          the LDAP backend too.
217         
218    - 1.21alpha14 :
219   
220        - dumpykota now supports extended filtering possibilities
221          with the PostgreSQL backend (LDAP support will come soon).
222         
223    - 1.21alpha13 :
224   
225        - Added a --debug command line option to pkpgcounter, so
226          that people may see what really happens, and what will
227          be available in the future :-)
228         
229    - 1.21alpha12 :
230   
231        - Fixed a bug with non standard pkbanner command lines.
232       
233        - Now logs as errors the differences between precomputed and
234          computed job sizes. **CUPS only for now**
235         
236    - 1.21alpha11 :
237   
238        - Now user and group print quota entries can be stored directly
239          below the user or group with the LDAP backend, using them
240          as branches. Thanks to Stefan Wold for the patch.
241          See the sample configuration file for details.
242         
243        - TLS is now supported with the LDAP backend. Thanks to Stefan
244          Wold for the patch.
245          See the sample configuration file for details.
246         
247        - edpkota now accepts the -U | --used value command line argument
248          to preset the page counters to an initial value. Thanks to
249          Wilson Roberto Afonso and Matt Hyclak for the patch.
250         
251    - 1.21alpha10 :
252   
253        - Now automatically reconnects up to three times if the LDAP server
254          returned an error, possibly due to a timeout.
255         
256    - 1.21alpha9 :
257   
258        - Now searches the configuration files in 'pykota' system user's
259          home directory. The 'pykota' system user and group have
260          to be created by the system administrator, and given
261          sufficient permissions to PyKota's configuration files.
262         
263    - 1.21alpha8 :

305         
306    - 1.21alpha1 :
307   
308        - added an IPP messages miniparser. Extraction of the client
309          hostname is now considered to be fiable, at least until
310          the CUPS developpers change something...
311       
312    - 1.20 :
313   
314        - Version number changed.
315

326          in the history.
327         
328        - Minor changes in the debian directory.
329       
330    - 1.20alpha27 :
331   
332        - Fixed many problems with translation files. In particular
333          the Brazilian Portuguese translation file was incorrectly
334          installed into the french "breton" locale directory.
335         
336        - Finished French translation. 
337         
338    - 1.20alpha26 :
339

346       
347    - 1.20alpha25 :
348   
349        - pkprinters allows --list to normal users, but require user
350          to be a PyKota administrator when another command line
351          option is used.

361       
362        - Now warnpykota only warns users who have ever printed,
363          to not cause confusion to users who have just opened
364          their account.
365       
366        - Prepared help messages for translations.

383          a PyKota administrator (a PyKota administrator is an user
384          allowed to read the pykotadmin.conf file).
385         
386        - Now any PyKota administrator can use repykota and warnpykota
387          with additionnal arguments, not only the root user.
388         
389        - Improved documentation a bit.
390

405          hexadecimal digest in the PYKOTAMD5SUM environment variable.
406         
407        - The description, filename, title, and options fields
408          are now stored as UTF-8 strings in both LDAP and PostgreSQL.

432          'pjl' value in the hardware accounter.
433         
434    - 1.20alpha15 :
435   
436        - LDAP pykotaAccountBalance objects were always created
437          attached to the pykotaUser objects. This is now
438          fixed and the value of balancebase in pykota.conf
439          is now correctly used.
440         
441    - 1.20alpha14 :
442

453        - Hardware accounter now accepts the special
454          'snmp' value, meaning ALL is done from main code
455          without launching any subprocess.
456          You need the http://pysnmp.sf.net Python module
457          for this to work (tested with v3.4.2)
458         
459        - Increased delay between two loops iterations 
460          to 2 seconds in waitprinter.sh to diminish
461          CPU load.
462         
463    - 1.20alpha12 :

465        - waitprinter.sh rewritten from scratch to wait
466          for printer status stabilization.
467       
468    - 1.20alpha11 :
469   
470        - Generic data dumper 'dumpykota' introduced.
471          Works only with PostgreSQL backend for now.
472         
473    - 1.20alpha10 :

497       
498        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
499          hostname or IP address. Set to 'localhost' when not
500          meaningful.
501         
502        - Fixed issue with how mod_auth_ldap Apache modules
503          fills the REMOTE_USER environment variable.

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

1039         
1040    - 1.18alpha4 :
1041   
1042        - Applied some of the modifications suggested by
1043          Peter Hawkins, for better Debian integration.
1044          Most notably cupspykota, pykota, and the shell
1045          scripts are now installed into /usr/share/pykota
1046          instead of into /usr/bin
1047          BEWARE : double check that your symbolic link
1048          to cupspykota is correct, and that your pykota.conf
1049          file use correct path for the shell scripts like
1050          waitprinter.sh and al.

1105          printing in CUPS backend.
1106         
1107        - Big fix wrt printing policies for unknown users. 
1108       
1109    - 1.16beta1 :
1110   
1111        - Manpages upgraded.

1116       
1117          SUM((NbPages * PricePerPage) + PricePerJob)
1118         
1119          For current printer and all the printers groups it is
1120          a member of, if any.
1121         
1122          This may be difficult to grasp, but offers unprecedented
1123          flexibility.

1163       
1164    - 1.16alpha18 :
1165   
1166        - Initial code for printer groups support. Printer groups have
1167          to be added with external tools like psql or gq for example.
1168          Printer groups seems to work fine with users. Untested with user
1169          groups for now.
1170
1171        - Several minor visual problems fixed in reports.
1172       
1173        - Fixed a bug in LDAP date handling.

1179          for details.
1180       
1181        - Several environment variables are now exported when executing
1182          external commands (accounters, requesters, mailers) :
1183           
1184            PYKOTAUSERNAME => user who is printing
1185            PYKOTAPRINTERNAME => printer on which the job is being sent
1186            PYKOTATITLE => Job's title
1187            PYKOTAFILENAME => Job's filename
1188            PYKOTACOPIES => number of copies asked
1189            PYKOTAOPTIONS => print command options (-o with CUPS)
1190         
1191    - 1.16alpha17 :
1192   
1193        - Added portugues translation.

1200          have nice looking and useful web based reports (in the future).
1201       
1202        - Added utolower configuration option to convert all usernames
1203          to lowercase during printing.

1210    - 1.16alpha14 :
1211   
1212        - Now printing on a printer not defined in the Quota Storage,
1213          results in the job being cancelled or stopped, depending
1214          on the printing system.
1215         
1216    - 1.16alpha13 :
1217   
1218        - Small bugfix wrt Python v2.1
1219       
1220        - If username is an empty string, user root is assumed.
1221       
1222        - 'postgresql' is not recognized anymore as a storage backend,
1223          you have to use 'pgstorage' instead. 'postgresql' used to
1224          be supported for compatibility with very old PyKota versions,
1225          this is not the case anymore.
1226         
1227    - 1.16alpha12 :
1228   
1229        - Job price added to job history, to keep accounting correct
1230          if a printer price per page or per job is modified and the
1231          history is not reset : the history would have given a false
1232          amount of money charged before the printer's prices were
1233          modified, this addition solves the problem.
1234         
1235    - 1.16alpha11 :
1236   
1237        - Some preliminary modifications to the database structure for
1238          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1239          database is now provided. LDAP attributes now support
1240          eq, pres and sub indexes.
1241         
1242        - Job history now contains additional informations : 
1243          number of copies, filename, title and print options.
1244         
1245    - 1.16alpha10 :
1246       
1247        - Some modifications done to external policy handling.
1248          See sample configuration file for details.
1249   
1250        - Spanish translation added.
1251       
1252    - 1.16alpha9 :
1253   
1254        - mailto can be set to external(...) to warn users above
1255          quota with any command of your choice (e.g. linpopup).
1256          Several parameters are available, see sample configuration
1257          file for details.
1258         
1259    - 1.16alpha8 :
1260   
1261        - Now cupspykota transmits SIGTERMS to the original 
1262          backend when the user deletes a job being processed.
1263         
1264        - The documentation is now licensed under the terms of the
1265          GNU GPL too.
1266         
1267    - 1.16alpha7 :

1269        - The CUPS backend is now fully functionnal (it seems).
1270       
1271        - From now on, the use of the pykota filter with CUPS
1272          is deprecated. The pykota filter still has to be
1273          used with LPRng though.
1274       
1275    - 1.16alpha6 :
1276   
1277        - Bug fixed : when edpykota was used to add a printer
1278          with no user or group name, a bad user/group name "*" was
1279          added to the database.
1280         
1281    - 1.16alpha5 :
1282   
1283        - New CUPS backend supports device enumeration !
1284          This means that NO manual CUPS configuration has to
1285          be done. All can now be done from CUPS web interface.
1286       
1287    - 1.16alpha4 :
1288   
1289        - New CUPS backend added.
1290       
1291    - 1.16alpha3 :

1311        - Command line tools now accept multiple printer
1312          names or wildcards, separated with commas.
1313         
1314    - 1.15alpha9 :
1315   
1316        - External policy can be used to auto-add unknown users
1317          and any other interesting things you may want to do.
1318          WARNING : You can't auto-add printers for now.
1319          They have to be created manually before.
1320          Look at sample configuration file for examples.
1321         
1322    - 1.15alpha8 :
1323   
1324        - Job history can be disabled if needed.
1325          This feature may be useful for people who use the LDAP
1326          backend and don't want their LDAP tree to grow out of
1327          control.
1328       
1329    - 1.15alpha7 :
1330   
1331        - More work done on caching wrt groups.

1340
1341    - 1.15alpha4 :
1342   
1343        - Problem with Python 2.3 fixed. Needs some definitive
1344          modification.
1345         
1346    - 1.15alpha3 :
1347   
1348        - CGI script now tries to restrict view when the
1349          REMOTE_USER environment variable is set. This allows
1350          people to protect its use with .htaccess files.
1351          When unprotected, or if REMOTE_USER is 'root', then
1352          unrestricted access is granted.
1353          NB : REMOTE_USER is automatically set by the web server
1354          (e.g. Apache) when a page with restricted access is viewed.
1355         
1356    - 1.15alpha2 :
1357   
1358        - Better detection of LPRng.
1359       
1360        - Outputs a warning if printing system is unknown.
1361       
1362    - 1.15alpha1 :
1363   
1364        - Bug fix in SQL code.
1365       
1366    - 1.14 :
1367   
1368        - The PostgreSQL database connection is now always closed before
1369          exit. The LDAP database connection too, but it didn't suffer
1370          from the problem anyway, AFAICT.
1371       
1372    - 1.14beta2 :
1373   
1374        - An LDAP-specific configuration field was introduced, usermail.
1375          Use it to specify which LDAP attribute contains a valid email
1376          address for the user. See sample configuration file for
1377          details.
1378       
1379    - 1.14beta :
1380   
1381        - Two new LDAP-specific configuration fields were introduced,
1382          newuser and newgroup. Use them to specify if you want to add
1383          quota information to existing entries or elsewhere.
1384          See sample configuration file for details.
1385         
1386    - 1.14alpha9 :
1387   
1388        - Documentation improved.
1389       
1390        - pykotme now also prints the user's account balance value
1391          if the user is registered in the Quota Storage and his
1392          limiting factor is "balance".
1393         
1394    - 1.14alpha8 :
1395   
1396        - bin/waitprinter.sh is now included to wait for
1397          SNMP enabled printers to be idle again before
1398          asking for their internal page counter.
1399          See sample configuration file for details.
1400         
1401    - 1.14alpha7 :
1402   
1403        - edpykota now doesn't check if the user/group is above
1404          quota. The check is only done at print time. This
1405          prevents the sending of email messages when creating
1406          user quotas if quota is already reached at creation
1407          time.
1408         
1409    - 1.14alpha6 :
1410   
1411        - Configuration file split and moved to /etc/pykota/pykota.conf
1412          and /etc/pykota/pykotadmin.conf to prevent simple users to
1413          have Read/Write access to the Quota Database.
1414          Don't forget to :
1415         
1416                $ chmod 640 /etc/pykota/pykotadmin.conf
1417               
1418        - storageuser and storageuserpw configuration fields reintroduced
1419          for the same reason.
1420         
1421        - Code cleaning for future implementation of email addresses
1422          support in the PostgreSQL and LDAP backends.
1423         
1424    - 1.14alpha5 :
1425       
1426        - Big bug fixed when changing the prices for a printer
1427       
1428    - 1.14alpha4 :
1429   
1430        - When adding an user, the user itself and its account balance
1431          are now added in the same LDAP entry. Before they were added
1432          as two different LDAP entries.
1433         
1434    - 1.14alpha3 :
1435   
1436        - Email field added to PostgreSQL database. An upgrade script

1446          balance (below 1.0 by default, configurable) are sent
1447          a warning message.
1448         
1449        - All warning messages to users are now configurable. 
1450          NB : Warning messages to the administrator are not.

1453   
1454        - Some small fixes wrt group handling.
1455       
1456        - The whole module code was passed through PyChecker and
1457          several small code inconsistencies were fixed,
1458          as well as a bug in the groups code.
1459         
1460    - 1.13alpha1 :

1482   
1483        - Bug fixed wrt quota reports when print limiting is by
1484          account balance.

1494    - 1.09beta2 :
1495   
1496        - The CGI script for quota reports works again, and
1497          is much more powerful.
1498       
1499    - 1.09beta :
1500   
1501        - edpykota finalized
1502       
1503    - 1.09alpha2 :
1504   
1505        - LDAP schema modified a bit. Please upgrade.
1506       
1507        - LDAP backend works !
1508       
1509        - repykota and warnpykota allow the root user to pass
1510          users or groups names on the command line. Users
1511          and groups names may contain wildcards.
1512         
1513        - repykota and warnpykota only reports or warns the
1514          current user when launched by non-root users.
1515         
1516        - Minor bug fixes. 
1517   
1518    - 1.09alpha1 :
1519   
1520        - More work on LDAP storage backend. Many options
1521          were added to /etc/pykota.conf to give some
1522          hints to the LDAP storage backend.
1523         
1524        - Severe database access optimizations were done by
1525          rewriting most of the Quota Storage backends drivers.
1526     
1527    - 1.08 :
1528   
1529        - Major bug fix wrt LPRng support for remote jobs.
1530       
1531        - Major bug fix wrt increase/decrease account balances.
1532       
1533    - 1.08alpha8 :
1534   
1535        - Code refactoring.
1536       
1537        - A single user/password pair is used to connect
1538          to the database backend. The storageuser configuration
1539          field, and its associated passwords storageuserpw, are
1540          not used anymore.
1541         
1542        - You can now set PyKota in debug mode, see sample configuration 
1543          file for details.
1544          WARNING : only Quota Storage backend queries are logged in
1545          debug mode, for now.
1546       
1547    - 1.08alpha7 :
1548   
1549        - Very latest LDAP schema.
1550       
1551        - Code enhancement wrt easy pluggability of PyKota attributes
1552          and object classes into an existing LDAP directory.
1553       
1554    - 1.08alpha6 :
1555   
1556        - Minor bug corrections
1557       
1558        - More work on LDAP : new schema
1559       
1560    - 1.08alpha5 :
1561   
1562        - More good work on LDAP storage.
1563          repykota now works reasonably well with the sample LDAP directory.
1564       
1565    - 1.08alpha4 :
1566   
1567        - LDAP schema included.
1568          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
1569          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1570          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1571          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1572          MAILING LIST.
1573         
1574    - 1.08alpha3 :
1575   
1576        - External accounting methods were partly rewritten :
1577         
1578          - No more "broken pipe" should happen.
1579         
1580          - They now take care of the number of copies
1581            This may be unneeded though, if the postscript
1582            file already does this, because this would
1583            overcharge users (number of copies counted
1584            two times). NEEDS MORE TESTING.
1585           
1586          - The sample configuration file now contains 
1587            an external accounting method example which should
1588            work with all DSC compliant Postscript files.
1589           
1590        - Some small bugs were fixed.   
1591       
1592    - 1.08alpha2 :
1593   
1594        - Now works with net-snmp v5.0 and above.
1595          It already worked, but the sample configuration
1596          file didn't contain appropriate values...
1597       
1598    - 1.07 : Release of the Shame !
1599   
1600        - The external accounting methods driver was left out of
1601          the CVS tree. Nobody could use it since it wasn't included !
1602         
1603    - 1.06 :
1604   
1605        - Severe bug fixed : if you had a printer in
1606          power saving state which couldn't answer immediately,
1607          a bug was triggered.
1608          It was caused by a bad copy/paste which
1609          forgot to import a Python module at run time.
1610         
1611    - 1.05 :
1612   
1613        - External accounters are finally available !
1614          This means that you can plug any page accounting
1615          method you like by setting the appropriate
1616          'accounter' field in /etc/pykota.conf
1617          See the sample conf/pykota.conf.sample to
1618          learn how to do.
1619         
1620          NB : Both 'external' and 'stupid' accounting methods
1621               account a job size just before *this* job is
1622               sent to the printer.
1623               The original 'querying' method accounts a job
1624               size just before *the next* job is sent to
1625               the printer.
1626       
1627    - 1.05alpha3 :
1628   
1629        - A 'stupid' and unreliable accounting method was
1630          implemented to serve as an example on how to
1631          do this sort of things. This method only counts
1632          the 'showpage' statements in the input data.
1633          See sample configuration file for details.
1634          Pluggable accounting methods work, but I advise
1635          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1636          It is not reliable enough to be used.
1637          Use the 'querying' accounting method instead.
1638         
1639    - 1.05alpha2 :
1640   
1641        - Pluggable accounting methods.
1642       
1643        - Better error handling.
1644       
1645    - 1.05alpha1 :
1646   
1647        - SECURITY file added to help improve PyKota's security.
1648       
1649        - Extracting the printer's internal page counter is now
1650          tried several times, waiting several seconds between
1651          two tries. This lets the time to warm up for some printers
1652          which don't answer when they are sleeping (my Apple
1653          LaserWriter 16/600 PS is in this case, maybe others too)
1654         
1655        - Small display bug fixed in repykota
1656         
1657    - 1.04 :
1658   
1659        - Default print policy for users/groups unknown from
1660          the print quota system is now DENY instead of ALLOW,
1661          since ALLOW can generate inaccurate results
1662          (incorrect job sizes charged to the wrong persons)
1663         
1664        - LPRng support works !
1665       
1666        - A bug was introduced some time ago wrt printers' default
1667          policy for unknown users. It is now corrected.
1668       
1669        - repykota now displays prices per job and per page for each
1670          printer, if they are defined.
1671         
1672        - Minor display bug fixed in repykota.
1673       
1674        - Problem when running repykota with an empty database was fixed.
1675       
1676    - 1.03 :
1677   
1678        - Upgrade script included for earlier versions.
1679          Please look inside the initscripts subdirectory.
1680          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1681         
1682        - repykota now reports account balances too.
1683       
1684        - PyKota now has a nice logo, see the logos
1685          subdirectory.
1686       
1687        - Manual pages were finally updated.
1688       
1689        - Group quotas seem to work now !
1690       
1691        - The new database schema allows to keep an history of all
1692          jobs as well as charge users per page and/or per job,
1693          and track users' account balance.
1694         
1695        - edpykota now accepts much more command line options to 
1696          use the new functionnalities. See edpykota --help for
1697          details.
1698         
1699        - The installation script now allows to install the sample
1700          configuration file during first installation.
1701         
1702        - More group quota code works, but still not finished. 
1703       
1704        - The CGI script displays a link to PyKota's website.
1705       
1706        - The job history is now kept, this will allow per-period
1707          reports in the future.
1708         
1709        - After having modified the quota for an user with edpykota,
1710          a quota check is done to eventually warn the user/admin about
1711          a quota which is too low to print.
1712         
1713        - A workaround is provided for HP Printers : their internal
1714          page counter is only saved to NVRAM in a 10 increment, so
1715          if you switch them off and then on, the reported page counter
1716          may be lower than the real number of pages printed.
1717          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1718          We unconditionnally set the last job's page count to
1719          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1720          in this case.
1721          For a more accurate accounting, never switch your HP printers
1722          off.
1723         
1724        - A fix is provided for printers which only have a volatile 
1725          page counter (reset to 0 every time you switch the printer on)
1726          This should allow PyKota to work reasonably fine with HP Laserjet
1727          4L/5L/6L, not perfect, but better than nothing.
1728          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1729          For a more accurate accounting, never switch your HP printers
1730          off. This is untested, please report any problem.
1731         
1732        - A bug was fixed when edpykota --add was used with users who already
1733          had a quota on the specified printer.
1734         
1735        - A small display bug in repykota was introduced in preliminary
1736          1.03 versions, and fixed later on.
1737         
1738        - Some minor bugs which happened in rare situations were fixed.
1739       
1740        - Support for AppleTalk printers was added, see sample configuration
1741          file for details.
1742         
1743        - Users and group printing can now be controlled (limited) either by 
1744          print quota or by account balance.
1745       
1746    - 1.02 :
1747   
1748        - The installation script now checks for software availability
1749          and in case a software is missing asks the user if he
1750          wants to continue with the installation or abort it.
1751         
1752        - The configuration file pykota.conf is now expected to be
1753          found in /etc instead of in /etc/cups
1754          The installation script prompts the user to see if he
1755          wants to move an old configuration file to the new location
1756          if needed.
1757         
1758        - Improved documentation.
1759       
1760        - You can now set the tcp/ip port on which the Quota Storage
1761          Server is listening, see sample configuration file for details.
1762       
1763        - Better general error handling.
1764       
1765        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1766          included as well.
1767       
1768    - 1.01 :
1769   
1770        - The configuration file now accepts an option   
1771          to choose the recipient(s) of the email messages :
1772         
1773            - DevNull means no one will receive them.
1774            - User means only the user will receive them.
1775            - Admin means only the admin will receive them.
1776            - Both means the User and the Admin will receive them.
1777           
1778        - The configuration file now uses hard-coded default values
1779          when an option is not set. See sample configuration file
1780          for details.
1781         
1782        - Manual pages are included since 1.00, but I forgot to   
1783          add this information to this file.
1784         
1785        - Redistribution terms for the official package have 
1786          softened and are now fully GPL compatible :
1787          unrestricted modification is now allowed even for
1788          the version number.
1789         
1790    - 1.00 :
1791   
1792        - edpykota now accepts a --noquota option. This
1793          disable quota checking while still doing page
1794          accounting. This is really useful for people
1795          who don't want to limit their users but want
1796          to know how much pages they print.
1797         
1798        - Some untested scripts were added to retrieve
1799          the life time page counter of non-SNMP printers.
1800         
1801        - Every directory now has a specific README file. 
1802       
1803    - 0.99 :
1804   
1805        - Under some circumstances while the user wasn't allowed
1806          to print, he didn't receive any email message. It is
1807          now fixed.
1808         
1809        - When an user wasn't allowed to print, the quota for
1810          the previous user wasn't updated. This is now fixed.
1811         
1812    - 0.98 :
1813   
1814        - Correctly handle the case where the printer is switched off.
1815       
1816        - Small bug wrt syslog fixed.
1817       
1818    - 0.97 :
1819   
1820        - edpykota accepts wildcards on its command line for users/groups too
1821          if the --add option is not set, e.g. :
1822         
1823              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1824             
1825        - If no user name is passed at all, then a default wildcard of "*"
1826          which means apply the command on ALL users for this printer is used.
1827         
1828        - Small bug fixes.
1829       
1830    - 0.96 :
1831
1832        - Options requester, policy, admin, adminmail and gracedelay can now
1833          be set either globally or per printer. The printer option has
1834          priority if both are defined.
1835
1836        - More powerful configuration parser.
1837       
1838        - If all options are defined globally, there's no need to
1839          define a section for each printer in the configuration
1840          file anymore. Just define a [global] section and it's ok.
1841
1842    - 0.95 :
1843
1844        - External requesters for printers finally added.
1845
1846        - Full internationalization (english and french are supported)
1847 
1848        - More complete quota usage report
1849
1850        - CGI script to access to the quota usage report
1851
1852        - Several bugs fixed.
1853
1854
1855    - 0.9 :
1856
1857        - First public version
