45       
46    - 1.25alpha18 (2006-11-30) :
47   
48        - Make the data dumper accept jobid= as an additional filter, just
49          like pkrefund and pkinvoice.
50       
51        - Make pkinvoice internally work like pkrefund.
52       
53        - Fixed a severe bug in the LDAP backend wrt the overcharging factor.

61          an english or C locale.
62         
63        - pknotify now accepts the --noremote command line option to
64          decide what has to be done when there's no PyKotIcon running
65          or accepting connections from the print server on the client host.
66         
67        - pkprinters now only modifies CUPS' printers.conf when the

82        - pkprinters --add and --delete now automatically reroutes CUPS
83          print queues through PyKota or through CUPS only.
84         
85        - Fixed date and time parsing problems.
86       
87        - Finally simplified the locking code again, and checked that no
88          stalled lock can persist. The lock files remain on disk though,
89          but it is a small price to pay.
90         
91    - 1.25alpha14 (2006-10-13) :
92     
93        - Removed some locking code which would have prevented multi-server
94          configuration to work correctly with a shared lock directory.
95         
96        - First useable release with the computation of ink
97          usage, through the introduction of the 'ink(cspace, resolution)'
98          value for the 'preaccounter' and 'accounter' directives in
99          pykota.conf

101    - 1.25alpha13 (2006-10-04) :
102     
103        - The dumpykota.cgi script now does basic form checking
104          to immediately avoid incompatible dump options and
105          alerts the end user if Javascript is enabled.
106         
107        - The filter keys in dumpykota can now be specified in
108          lower or upper case.
109         
110        - Introduced the 'noprintingmaxdelay' directive to workaround
111          some buggy printers when hardware accounting is used.
112         
113        - Improved the reliability of hardware accounting. 
114

121   
122        - Now fails in an helpful manner if python-mysqldb is too old.
123       
124        - Now exports the original username and billing code (i.e.
125          their values before they are eventually overwritten) in
126          two additionnal environment variables.
127         
128    - 1.25alpha10 (2006-09-03) :
129   
130        - Rewrote the locking mechanism to try to fix the problem

137          of the python-chardet module as a dependency.
138         
139    - 1.25alpha9 (2006-08-10) :
140   
141        - Fixed a problem when an SMTP error occured and the recovery
142          routine failed to handle it correctly.

155    - 1.25alpha6 (2006-06-13) :
156   
157        - pkusers now supports the --email command line switch.
158          The old method to set the email address is still supported,
159          but the new one allows the email address to be modified
160          as well.

163   
164        - Fixed the incorrect overwriting of the original billing
165          code if the overwrite_jobticket directive was used.

171        - Fixed MySQL schema to workaround some "features"...
172       
173    - 1.25alpha4 (2006-05-23) :
174   
175        - Introduced the 'askconfirmation' directive to interact with
176          the end user through any script (pknotify is recommended)
177          and see if he really wants to print when knowing the cost
178          of the job.
179         
180        - Now uses pkipplib if present to directly retrieve the job
181          information from the CUPS server over IPP.
182         
183    - 1.25alpha3 (2006-05-11) :
184   
185        - Added a lock to ensure that a single cupspykota backend
186          is processing datas for a particular print queue at any
187          given time.
188         
189        - Now exports more environment variables for the subprocesses.

206    - 1.24 (2006-04-08) :
207   
208        - Improved documentation and packaging stuff.
209       
210    - 1.24beta (2006-03-26) :
211   
212        - Finalized the pknotify command.
213       
214        - Updated the messages catalogs for translations.
215       
216    - 1.24alpha18 (2006-03-15) :
217   
218        - Now uses MIME encapsulation for email messages to avoid
219          some problems with 8 bits messages being rejected.

230          with remote PyKotIcon applications.
231         
232    - 1.24alpha15 (2006-03-02) :
233       
234        - optimized pkbcodes, pkprinters and pkusers using edpykota as
235          the model.
236       
237        - 'edpykota --list' and 'pkusers --list' are now authorized
238          to mere mortal users, but the list is restricted to informations
239          about the current user.
240       
241        - Extended the functionnality of the 'onbackenderror' directive to
242          allow for configurable retries.
243         
244    - 1.24alpha14 :
245   
246        - Finished optimizations in edpykota and fixed some minor
247          problems with LDAP.
248         
249    - 1.24alpha13 :
250   
251        - Introduced the pkusers command line tool to manage users and 
252          users groups. This command doesn't deal with print quota entries,
253          which continue to be managed through the edpykota command line
254          tool.
255         
256        - Major rewrite and incompatible changes to command line options
257          in edpykota. This command now only deals with print quota
258          entries. Printers, users (or users groups) now have to be created
259          first using pkprinters or pkusers.
260         
261    - 1.24alpha12 :
262   
263        - Introduced the 'duplicatesdelay' directive to specify after
264          which duration two duplicate jobs are not considered duplicate
265          jobs anymore.
266         
267        - Introduced the 'balancezero' directive to specify any value 
268          as the balance limit instead of 0.0. This can allow admins to
269          give a few free credits to users, for example.
270         
271    - 1.24alpha11 :
272   
273        - Huge speed improvements when modifying billing codes and
274          printers.
275       
276        - Both pkbcodes and pkprinters now display the percent done
277          for all actions.
278         
279        - The pkinvoice invoice generator command line utility is now
280          included.
281         
282    - 1.24alpha10 :   
283   
284        - Huge speed improvements when deleting users, printers, and
285          billing codes.
286         
287    - 1.24alpha9 :
288   
289        - Preliminary support for MySQL, thanks to Matt Hyclak.
290       
291    - 1.24alpha8 :
292   
293        - The 'preaccounter' configuration directive was introduced to control
294          which parser to use for precomputation of the job's size. When unset,
295          the internal parser is used just like it was previously. See
296          conf/pykota.conf.sample for more details.
297         
298        - Now subprocesses launched through the overwrite_jobticket directive
299          can also output 'CANCEL', to represent the user's own choice to
300          cancel the print job.
301         
302    - 1.24alpha7 :
303     
304        - pkbanner now handles new print limiting modes correctly.
305       
306        - The cupspykota backend wrapper now accepts to be interrupted
307          with a kill -INT. This causes an immediate and clean abort
308          of the current print job.
309         
310        - Matt Hyclak contributed the possibility to store the printing
311          history in a MySQL database. See the contributed/ directory
312          for details.
313         
314        - Added 2006 to the copyright's years.
315       
316    - 1.24alpha6 :
317   
318        - Fixed internal SNMP and PJL handling code for very fast
319          printers : PyKota didn't see them going from 'idle'
320          to 'printing' to 'idle' again.
321         
322        - Now waitprinter.sh accepts SNMP version number and
323          community name as arguments, thanks to Brandon
324          Holbrook.
325         
326        - Now command line errors and Ctrl+C repectively cause
327          PyKota commands to exit with status -2 and -3.
328         
329    - 1.24alpha5 :
330   
331        - All command line tools now accept -A | --arguments filename.args
332          as a way to bypass the shell's maximal command line size :
333          just put each argument on a line by itself in a file, and
334          pass the file's name as the -A | --arguments command line
335          option's argument. For now this won't be documented in
336          commands' helps.
337         
338        - dumpykota can now dump the complete database in XML
339          format.
340         
341    - 1.24alpha4 :
342   
343        - Added support for the SQLite3 backend.
344          See pykota/initscripts/sqlite/README.sqlite
345       
346    - 1.24alpha3 :
347   
348        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
349          so we regain priviledges before running an external
350          mailto directive.
351       
352    - 1.24alpha2 :
353   
354        - Introduce the "onbackenderror" directive in pykota.conf, to
355          control if the user must be charged or not whenever a real
356          CUPS backend fails. The default value is 'nocharge'.
357          Set it to 'charge' if you think your users can cause a CUPS
358          backend to fail.
359         
360        - Now mark original backends related problems as such in the
361          printing history. Modified printquota.cgi and pykota.css
362          to make them be more visible.
363         
364    - 1.24alpha1 :
365   
366        - Fixed a problem which caused backend errors to be ignored.
367       
368        - The sample LDIF file now contains the two necessary user
369          entries to have an LDAP PyKota Admin and an LDAP PyKota
370          ReadOnly user. The sample configuration files were updated
371          to contain the default passwords used in the LDIF file.
372         
373        - dumpykota is now more strict when checking arguments.   
374       
375    - 1.23 :
376   
377        - Many minor bug fixes and code cleaning.
378       
379        - Improved documentation.
380       
381        - Added Polish translation.
382       
383        - Improved French and Swedish translations.
384       
385    - 1.23beta :
386   
387        - Now the mailto directive is honored in all cases where the job is
388          denied or a warning has to be issued, and the correct reason
389          can be sent back to the user.
390         
391        - The PYKOTAREASON environment variable, if defined, contains the 
392          textual reason why the job was denied or a warning has to be
393          issued.
394       
395    - 1.23alpha31 :
396   
397        - Added support for --maxjobsize, --passthrough and --nopassthrough
398          in pkprinters. These modes are now also honored when printing.
399         
400        - Allows the admin to restrict the number of print queues which will
401          be treated by pkturnkey by passing queues' names as additionnal
402          arguments on pkturnkey's command line.
403         
404        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
405          command line option.   
406         
407    - 1.23alpha30 :
408   
409        - Database changes : you MUST use upgrade-to-1.23.sql again if you
410          use PostgreSQL, or copy the new schema and restart your LDAP
411          server if you use LDAP.
412         
413        - The -C | --comment command line switch was added to edpykota to 
414          attach textual information to modifications done to a user's
415          account balance.
416         
417        - The -l | --limitby command line switch to edpykota was modified 
418          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
419          command's help or manual page for details.
420         
421        - The -i | --ingroups command line switch to repykota allows 
422          PyKota Administrators to only lists members of the specified
423          group or groups (separated with commas).
424         
425        - The -I | --increase command line switch to edpykota allows
426          to increase or decrease page limits.
427         
428        - Added the precomputed job's size and price to the history
429          for controlling purpose.
430       
431    - 1.23alpha29 :
432   
433        - Fixed a small problem with billing codes.
434       
435        - Exports some environment variables earlier, to render the script
436          launched by the overwrite_jobticket directive more powerful.
437         
438        - Now autopykota also creates print quota entries for the user on the
439          printers groups the current printer is a member of.
440         
441    - 1.23alpha28 :
442   
443        - Added users groups management to pkturnkey.
444       
445        - Fixed umask in setup script.
446       
447    - 1.23alpha27 :
448   
449        - Replaced the --dryrun command line option by the --force
450          command line option in pkturnkey, with exactly the opposite
451          effect (for security reasons).
452         
453    - 1.23alpha26 :
454   
455        - Allows parametrized pjl and snmp hardware accounting methods,
456          to be able to respectively set the TCP port and the SNMP
457          community.
458         
459    - 1.23alpha25 :
460   
461        - Added a --dryrun command line switch to pkturnkey.
462       
463        - Improved pkturnkey's general usability.
464       
465        - Added a manpage for pkturnkey.
466       
467    - 1.23alpha24 :
468   
469        - Allows different databases to be used depending on the
470          user's rights. This allows PyKota admins to directly
471          use a master LDAP server for read+write, while letting
472          normal users using the replicas for readonly access.
473          NB : using different storage backends is also possible,
474          but you're on your own there.
475

479   
480        - Introduction of the new 'pkturnkey' command line tool.
481       
482    - 1.23alpha22 :
483   
484        - The cupspykota backend was almost entirely rewritten from scratch.
485          It's now much more readable, maintainable, etc...
486         
487        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
488          advised to download earlier releases or purchase the
489          PyKota v1.22HotFix1 Official release. LPRng support
490          MIGHT be re-added later.
491       
492    - 1.23alpha21 :
493     
494        - Fix for IPP requests which contain more than a single
495          job-originating-host-name attribute.
496         
497    - 1.23alpha20 :
498   
499        - Added the overwrite_jobticket directive. See pykota.conf.sample
500          for how to use it.
501         
502    - 1.23alpha19 :
503   
504        - Fixed an LDAP filtering problem when managing billing codes.
505       
506        - Added the unknown_billingcode directive. See pykota.conf.sample

509    - 1.23alpha18 :
510     
511        - Added the dump_bfd.php contribution.
512       
513        - Several fixes in the internal PJL accounter.

516       
517        - Increased the timeout in the PJL hardware accounting code to
518          accomodate some printers (HP5000 at least).
519         
520    - 1.23alpha17 :
521   
522        - pkpgcounter is now distributed separately only. This
523          means that people must now download and install pkpgcounter
524          v1.56 or higher prior to being able to run PyKota.
525         
526        - Removed all the autoconf/automake stuff which was outdated 
527          and confusing.
528         
529    - 1.23alpha16 :
530     
531        - Extracted the GPL blurb from all commands' help, and use
532          a static version only once. This saves space big time, and
533          eases future translations.
534         
535    - 1.23alpha15 :
536   
537        - pkbcodes now works with the PostgreSQL backend.
538          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
539       
540    - 1.23alpha14 :
541

548       
549    - 1.23alpha12 :
550   
551        - Big database changes, use the migration scripts !
552       
553    - 1.23alpha11 :
554   
555        - Small fix to the PCL3/4/5 parser for some drivers.
556       
557    - 1.23alpha10 :
558   
559        - Fixed a bad exception name in cupspykota when parsing IPP messages.
560       
561        - Improved the IPP messages module : it can now generate IPP messages
562          in addition to parsing them.
563       
564    - 1.23alpha9 :   
565   
566        - The denyduplicates directive now accepts a command line as an
567          argument beside yes/no. The command is launched and must
568          print either ALLOW or DENY to its standard output. Then the
569          job gets allowed or denied by PyKota.
570          This will allow user interaction in the near future.
571         
572        - Introduced the new 'striptitle' directive to remove ugly prefixes
573          from print job's titles whenever a new print job is submitted.
574         
575        - Fixed internal SNMP accounter for printers which only have a life time
576          page counter, and not a volatile page counter.
577         
578    - 1.23alpha8 :
579   
580        - The data dumper can now summarize payments and history with the
581          help of the --sum command line option (or checkbox in the CGI).
582         
583        - The message used when the job's filename, title and options are
584          hidden because of the privacy directive is now translated at
585          retrieval time, instead of at saving time.
586         
587        - Minor fix in the LDAP backend code. 
588         
589    - 1.23alpha7 :
590   
591        - Improvements to the internal PJL and SNMP accounter : now should
592          support more printers and waste less time.
593         
594    - 1.23alpha6 :
595   
596        - The data dumper's start= and end= date filtering options now
597          accept a positive or negative offset to be added to the special
598          keywords 'yesterday', 'today', 'now', 'tomorrow'.
599          e.g. : dumpykota --data history start=yesterday-5 end=today
600         
601    - 1.23alpha5 :
602   
603        - The data dumper's start= and end= date filtering options now accept
604          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
605         
606    - 1.23alpha4 :
607   
608        - The data dumper now accept start= and end= to specify the starting
609          and ending dates to dump the history.
610         
611    - 1.23alpha3 :
612   
613        - The destination link for the logo used in CGI scripts is
614          configurable.
615         
616        - Data dumper improved : it's faster and now datas are correctly
617          escaped.
618       
619        - The URL to the logo displayed in the CGI scripts is configurable.
620       
621    - 1.23alpha2 :
622   
623        - Fixed edpykota --prototype with balance.
624

629   
630        - Sets current username to the user CUPS runs as instead of "root"
631          when printing test pages from CUPS' web interface (because
632          the username is empty in this case).
633         
634        - Fix for strange values in job-originating-hostname
635       
636    - 1.22 :
637   
638        - Big improvements to the documentation.
639

646        - Fixed an inconsitency between SQL and LDAP backends'
647          behavior in edpykota.
648

669         
670        - Ctrl+C now makes PyKota commands exit without a traceback.
671

693    - 1.22alpha3 :
694   
695        - Fixes some case related problems with some LDAP backends.
696       
697        - Fixes some problem for printers which directly go from
698          "idle" to "warmup" and never to "printing" before
699          returning to "idle".
700         
701        - Some permissions settings may have prevented cupspykota
702          from parsing cupsd.conf, this is now fixed.
703         
704    - 1.22alpha2 :
705   
706        - Introduction of the web enabled print quote generator.
707       
708        - Fixed a potential race condition when several backend
709          wrappers were present in CUPS' backend directory.
710         
711        - Fixed dumpykota's output in CUPS' page_log format to better
712          match CUPS format.
713         
714    - 1.22alpha1 :
715   
716        - Import into Subversion.

739    - 1.21alpha27 :
740   
741        - Allows software() (no arguments) to the software accounting
742          directive. This saves a lot of CPU since the job is not
743          parsed again : the precomputed size is used directly in this
744          case.
745         
746        - epykota's --prototype option now works fine with accounts
747          limited by balance.

760          'enforcement' is not set to 'strict'.
761         
762        - Introduction of the new 'trustjobsize' configuration directive
763          to workaround some problematic printers. See the sample
764          configuration file for details.
765         
766    - 1.21alpha24 :
767   
768        - Big database structure changes. An upgrade script
769          is now included for PostgreSQL. LDAP users may just
770          want to copy the new schema in place.
771         
772        - edpykota now recognizes the -o | --overcharge command line
773          option to set an overcharging or undercharging factor
774          on each print job's cost for a particular user.
775         
776        - repykota's output format has changed an is not limited to 
777          80 characters wide anymore. People who used to parse
778          repykota's output in their own tools are strongly advised
779          to parse dumpykota's output instead.
780         
781        - Introduction of the new 'maxdenybanners' configuration directive
782          to allow up to N (the directive's value) deny banners to be
783          printed even if the print account is forbidden to print.
784         
785        - Better detection of the number of copies in the PostScript parser.
786       
787    - 1.21alpha23 :
788

792       
793    - 1.21alpha22 :
794   
795        - edpykota's --delete command line option doesn't consider
796          '*' to be the default argument anymore :-)
797         
798    - 1.21alpha21 :
799   
800        - dumpykota.cgi can now be run as a normal user as opposed to
801          a PyKota administrator. No read access to pykotadmin.conf is
802          necessary anymore. This CGI scripts now honors the REMOTE_USER
803          environment variable just like printquota.cgi does, see
804          the file cgi-bin/README for details.
805          The command line tool dumpykota must still be run by a PyKota
806          administrator.
807         
808        - Fix exception's name error due to a change in recent versions
809          of PygreSQL.   
810         
811    - 1.21alpha20 :
812         
813        - Big bug fix wrt the datelimit field which was never reset.
814         
815    - 1.21alpha19 :
816   
817        - Introduction of the new dumpykota.cgi CGI script, which
818          allows third party tools like phpPrintAnalyzer to be
819          interfaced in real time with PyKota. To use it you
820          may have to change your web server's configuration,
821          please see pykota/cgi-bin/README
822         
823    - 1.21alpha18 :
824   
825        - Now dumpykota can dump the job history into CUPS' page_log
826          format (even when the printing system is LPRng). This allows
827          people to use tools like PrintAnalyzer or phpPrintAnalyzer
828          (two completely different beasts) with PyKota.
829         
830    - 1.21alpha17 :
831     
832        - Fixed field type's name in XML dumps.
833       
834        - Now drops priviledges to user 'pykota' when launched as root
835          (directly or as a CUPS backend), if such an user exists.

837        - Fixed PCL3/4/5 parser for some drivers' output.
838

847          in dumpykota's output.
848         
849        - dumpykota filtering capabilities are now supported within
850          the LDAP backend too.
851         
852    - 1.21alpha14 :
853   
854        - dumpykota now supports extended filtering possibilities
855          with the PostgreSQL backend (LDAP support will come soon).
856         
857    - 1.21alpha13 :
858   
859        - Added a --debug command line option to pkpgcounter, so
860          that people may see what really happens, and what will
861          be available in the future :-)
862         
863    - 1.21alpha12 :
864   
865        - Fixed a bug with non standard pkbanner command lines.
866

871   
872        - Now user and group print quota entries can be stored directly
873          below the user or group with the LDAP backend, using them
874          as branches. Thanks to Stefan Wold for the patch.
875          See the sample configuration file for details.
876         
877        - TLS is now supported with the LDAP backend. Thanks to Stefan
878          Wold for the patch.
879          See the sample configuration file for details.
880         
881        - edpkota now accepts the -U | --used value command line argument
882          to preset the page counters to an initial value. Thanks to
883          Wilson Roberto Afonso and Matt Hyclak for the patch.
884         
885    - 1.21alpha10 :
886   
887        - Now automatically reconnects up to three times if the LDAP server
888          returned an error, possibly due to a timeout.
889         
890    - 1.21alpha9 :
891   
892        - Now searches the configuration files in 'pykota' system user's
893          home directory. The 'pykota' system user and group have
894          to be created by the system administrator, and given
895          sufficient permissions to PyKota's configuration files.
896         
897    - 1.21alpha8 :
898   
899        - Added the new reject_unknown directive to reject the
900          creation of user or groups which are unknown to the system.

939         
940    - 1.21alpha1 :
941   
942        - added an IPP messages miniparser. Extraction of the client
943          hostname is now considered to be fiable, at least until
944          the CUPS developpers change something...
945       
946    - 1.20 :
947   
948        - Version number changed.

975          printers' hostnames or IP addresses.
976         
977        - Fix for recently introduced bug in LPRng support.
978       
979        - Fix for incorrect locale setting when starting.
980       
981    - 1.20alpha25 :
982   
983        - pkprinters allows --list to normal users, but require user
984          to be a PyKota administrator when another command line
985          option is used.
986         
987        - pkhint doesn't use absolute path to search for helper commands
988          anymore.
989         
990        - Spanish translation ready for 1.20.   
991       
992    - 1.20alpha24 :
993   
994        - Now warnpykota only warns users limited by balance once.
995       
996        - Now warnpykota only warns users who have ever printed,
997          to not cause confusion to users who have just opened
998          their account.
999       
1000        - Prepared help messages for translations.
1001       
1002    - 1.20alpha23 :
1003   
1004        - Add workaround for locale problem.
1005       
1006    - 1.20alpha22 :
1007   
1008        - Hopefully final fix for data encoding charset.
1009       
1010        - edpykota now refuse to work if the user is not a PyKota admin.
1011       
1012        - Fixes a recently introduced bug with users groups and PostgreSQL.
1013       
1014    - 1.20alpha21 :
1015   
1016        - Now dumpykota refuses to launch if the current user is not
1017          a PyKota administrator (a PyKota administrator is an user
1018          allowed to read the pykotadmin.conf file).
1019         
1020        - Now any PyKota administrator can use repykota and warnpykota
1021          with additionnal arguments, not only the root user.
1022         
1023        - Improved documentation a bit.
1024       
1025    - 1.20alpha20 :
1026   
1027        - Reduced delay in internal SNMP and PJL_over_TCP handlers
1028          from 2 to 1 second.
1029       
1030        - dumpykota can now output XML.
1031       
1032    - 1.20alpha19 :
1033   
1034        - Improved user groups and user groups quotas dumps in dumpykota.
1035       
1036        - Finished implementation of LDAP support in dumpykota.
1037       
1038        - The md5 sum of the job's datas is now available as an
1039          hexadecimal digest in the PYKOTAMD5SUM environment variable.
1040         
1041        - The description, filename, title, and options fields
1042          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
1043          Proper charset is used during extraction from the database.
1044         
1045    - 1.20alpha18 :
1046   
1047        - Experimental autopykota command to initialize user
1048          account and quota entries on first print while not
1049          resetting the balance value if not needed.
1050         
1051        - Added the new "winbind_separator" directive to strip
1052          out the Samba/Winbind domain name while printing if
1053          needed (Off by default).
1054         
1055    - 1.20alpha17 :
1056   
1057        - Added --hardreset command line option to edpykota.
1058       
1059        - Fixed problem with accented chars in title, filename
1060          or options and LDAP backend.
1061         
1062    - 1.20alpha16 :
1063   
1064        - Internal handling of socket based PJL queries over
1065          port tcp/9100 is now available with the magic
1066          'pjl' value in the hardware accounter.
1067         
1068    - 1.20alpha15 :
1069   
1070        - LDAP pykotaAccountBalance objects were always created
1071          attached to the pykotaUser objects. This is now
1072          fixed and the value of balancebase in pykota.conf
1073          is now correctly used.
1074         
1075    - 1.20alpha14 :
1076   
1077        - Belgian translations added (copy of the french ones).
1078       
1079        - External hardware accounter now loops until
1080          a result can be read correctly.
1081         
1082        - pkhint now suggest the internal snmp handling instead
1083          of the external one.
1084         
1085    - 1.20alpha13 :
1086     
1087        - Hardware accounter now accepts the special
1088          'snmp' value, meaning ALL is done from main code
1089          without launching any subprocess.
1090          You need the http://pysnmp.sf.net Python module
1091          for this to work (tested with v3.4.2)
1092         
1093        - Increased delay between two loops iterations 
1094          to 2 seconds in waitprinter.sh to diminish
1095          CPU load.
1096         
1097    - 1.20alpha12 :
1098   
1099        - waitprinter.sh rewritten from scratch to wait
1100          for printer status stabilization.
1101       
1102    - 1.20alpha11 :
1103   
1104        - Generic data dumper 'dumpykota' introduced.
1105          Works only with PostgreSQL backend for now.
1106         
1107    - 1.20alpha10 :
1108   
1109        - Added fix for incorrect job's size computation when
1110          hardware accounting fails.
1111         
1112    - 1.20alpha9 :
1113   
1114        - Small fixes wrt subprocesses.
1115       
1116    - 1.20alpha8 :
1117   
1118        - Added full support of PCL3 : HP Deskjet printers are now
1119          supported.
1120       
1121    - 1.20alpha7 :
1122   
1123        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
1124          Needs more work, but no documentation is available.
1125       
1126    - 1.20alpha6 :
1127     
1128        - Improved mailandpopup.sh script.
1129       
1130        - Small fixes for LPRng.
1131       
1132        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
1133          hostname or IP address. Set to 'localhost' when not
1134          meaningful.
1135         
1136        - Fixed issue with how mod_auth_ldap Apache modules
1137          fills the REMOTE_USER environment variable.
1138         
1139        - Fixed a bug in LDAP user deletion code.
1140       
1141    - 1.20alpha5 :
1142     
1143        - Introduces the new configuration directive 'onaccountererror'
1144          to specify what must be done whenever the software or
1145          hardware accounter fails. Allowed values are 'continue' and
1146          'stop' (default).
1147         
1148        - Minor fix in software accounter for a recently introduced
1149          problem.
1150         
1151    - 1.20alpha4 :
1152   
1153        - Added support for more ghostscript devices in ESC/P2
1154          analyzer : stcolor, st800, escp, escpc are now supported.
1155         
1156    - 1.20alpha3 :
1157       
1158        - Small improvement in PostScript parser to avoid being
1159          fooled by a change in number of copies :
1160          The user can't ask for 200 copies of page 1 and 1 copy
1161          of page 2 to fool PyKota anymore :
1162          this would have been accounted for as 1 copy only, but
1163          now the maximum value seen is used.
1164         
1165        - Relax checks for PCL5 header to accomodate some strange
1166          printer drivers.
1167         
1168        - Now hardware accounting method works like software
1169          accounting method wrt the subprocess' output.
1170         
1171        - Hardware and Software accounting stop the print queue 
1172          when the accounting subprocess didn't work. This will
1173          be configurable in the near future.
1174         
1175    - 1.20alpha2 :
1176   
1177        - Now software accounting method reads accounter's
1178          answer until a line with a single integer is
1179          obtained or until all of its output has been read.
1180          This should fix the problem some people have
1181          when strange locale related messages are sent
1182          when running subprocesses (Solaris only ?).
1183         
1184        - First version of ESC/P2 analyzer. Seems to work
1185          ok at least with 'epson', 'epsonc', 'eps9mid'
1186          and 'esp9high' ghostscript devices. Needs more
1187          work to correctly analyze other devices.
1188       
1189    - 1.20alpha1 :
1190   
1191        - Fixed problem with number of copies in PCLXL parser.
1192       
1193        - Fixed problem with number of copies in PCL5 parser,
1194          when number of copies was set outside of and before first
1195          page.
1196       
1197        - Added workaround for number of copies directly set in
1198          PostScript code.
1199         
1200        - Added german translation.
1201       
1202        - Fixed problem on first print for user group quota when
1203          "enforcement: strict" is used.
1204       
1205        - Fixed interpolation problem in french translation.
1206       
1207    - 1.19 :
1208   
1209        - Updated existing translations.   
1210       
1211        - Added final Thai and Greek translations.
1212       
1213        - Minor last minute bug fixes.
1214       
1215    - 1.19beta :
1216   
1217        - LPRng support for both software and hardware accounting seems
1218          to be OK.
1219         
1220        - Translation files fixed because of fuzzy matching problem. 
1221       
1222        - Fixed path to Swedish translation: 'sv' instead of 'se'.
1223       
1224        - Added first draft of Thai translation.
1225       
1226        - Fixed some minor bugs with Pychecker.
1227       
1228    - 1.19alpha35 :
1229   
1230        - Generic PDL analyzer now supports Binary PostScript documents
1231          in addition to DSC compliant ones.
1232       
1233    - 1.19alpha34 :
1234   
1235        - LPRng support : software accounting seems to work fine,
1236          but hardware accounting doesn't work yet.
1237   
1238    - 1.19alpha33 :
1239   
1240        - pykosd now accepts command line arguments. Enjoy !
1241          NB : due to a bug in xosd, you need xosd version 2.2.8
1242          or higher if you don't use the default C locale.
1243         
1244    - 1.19alpha32 :
1245   
1246        - Early (not working) version of the LPRng support rewrite.
1247       
1248        - Saner default configuration file.
1249       
1250    - 1.19alpha31 :
1251   
1252        - Fixed a double Python2.1 incompatibility with newer versions,
1253          which prevented the PCL5 and the PCLXL parsers to work with
1254          this older version of Python.
1255         
1256    - 1.19alpha30 :
1257   
1258        - Introduction of preliminary version of the pykosd command
1259       
1260        - Usernames, Groupnames and Printernames can now contain
1261          ANY character, expected '/' and '@'.
1262       
1263        - Integrated most of the Debian work from Sergio
1264          Gonz�z Gonz�z
1265         
1266    - 1.19alpha29 :
1267   
1268        - PCLXL parser should now correctly handle number of
1269          copies set for each page.
1270         
1271        - Added testsuite for generic PDL analyzer.
1272       
1273        - Typo fixed in PCLXL parser.
1274       
1275        - Correctly dispatches error messages depending on the
1276          situation : tools which can be run interactively will
1277          ALWAYS output their logs to stderr, excepted for
1278          their DEBUG messages, for which the "logger:"
1279          directive as set in pykota.conf will be honored.
1280          Tools which can't be run interactively will ALWAYS
1281          honor the "logger:" directive as set in pykota.conf
1282         
1283    - 1.19alpha28 :
1284   
1285        - The description field for printers can now be set,
1286          and is displayed in reports.
1287         
1288        - Fixed a small problem in SQL backend code.
1289         
1290        - Improved pkhint
1291       
1292        - First working PCL6 (aka PCLXL) parser !
1293          Doesn't handle copies yet.
1294       
1295    - 1.19alpha27 :
1296   
1297        - Additionnal 10% speed increase in PCL5 parser for GhostScript
1298          generated files (untested yet with other PCL files).
1299         
1300        - Reintroduced the use of mmap in PCL5 parser : this speedups
1301          PCL5 parsing by almost 4 times.
1302          This 4x with the 3x below give us in fact a twelvefold increase
1303          in performance for PCL5 parsing !
1304         
1305        - The Python accelerator Psyco is now used if available
1306          in the generic PDL parser : it speedups PCL5 parsing by
1307          almost three times automagically.
1308         
1309    - 1.19alpha26 :
1310   
1311        - Fixed PCL5 parser according to the sources of rastertohp.
1312       
1313        - Fixed number of copies handling in PCL5 parser : the number
1314          of copies could vary from page to page.
1315         
1316        - Added more debug information to PCLXL parser. 
1317       
1318    - 1.19alpha25 :
1319   
1320        - Added new "description" field to printers in both
1321          PostgreSQL and LDAP. No code to handle this yet.
1322         
1323        - Reversed the fix for power save mode in printers : 
1324          no paper or tray open would have caused people to
1325          be undercharged.
1326         
1327        - Preliminary version of MySQL initialization script.
1328         
1329    - 1.19alpha24 :
1330   
1331        - Native PDF parsing code now works perfectly with
1332          Python 2.1 and above, and is way faster than before.
1333          GhostScript is not used anymore to convert PDF to PS,
1334          because PDF is parsed directly.
1335         
1336    - 1.19alpha23 :
1337   
1338        - Fixed waitprinter.sh wrt PowerSave mode and some
1339          printers. Thanks to Ryan Suarez.
1340       
1341        - Smart PDL analyzer now recognizes PDF too : two
1342          PDF parsing methods are used : a native one which
1343          is very fast but requires Python 2.3 or above, and
1344          a slower one which uses Ghostscript. PyKota detects
1345          automatically which method to use depending on your
1346          version of Python.
1347       
1348        - All tracebacks now include PyKota's version number.
1349         
1350    - 1.19alpha22 :
1351   
1352        - Ensures that the file pointer for job's data is
1353          reset to the start of the job's datas after the
1354          job's size pre-computation phase.
1355         
1356        - Improved PostScript detection code for bad drivers
1357          which don't correctly switch languages between PJL
1358          and PS.
1359       
1360        - Even better debugging code.
1361       
1362    - 1.19alpha21 :
1363   
1364        - Additionnal check.
1365       
1366    - 1.19alpha20 :
1367   
1368        - More complete logging messages wrt accounters.
1369       
1370        - Now catches early failures occuring when the configuration
1371          files are parsed.
1372       
1373    - 1.19alpha19 :
1374   
1375        - Fixed over-verbose exits when displaying help
1376          or version.
1377         
1378        - Extended some PATH in the shell scripts 
1379       
1380        - Deleting an user now also deletes his payments history.
1381       
1382        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
1383          cause problems.
1384
1385    - 1.19alpha18 :
1386   
1387        - History of payments is now stored in the database, and
1388          updated each time an user's balance is modified with
1389          edpykota --balance. This history represents each time
1390          the user was given some positive or negative credit,
1391          but doesn't reflect price paid for jobs, which appear
1392          in the jobs history instead.
1393         
1394        - Jobs history web reports now include the job's size in
1395          bytes. Also columns were reordered to render the report
1396          more easily readable.
1397         
1398    - 1.19alpha17 :
1399   
1400        - Mysterious bug (program exited unexpectedly without leaving
1401          any log message) which occured once in a while when
1402          cancelling jobs should be fixed now.
1403         
1404        - New 'crashrecipient' directive. Disabled by 
1405          default. See sample configuration file to see how
1406          to activate it. It is suggested that you activate it.
1407         
1408        - New PYKOTAJOBSIZEBYTES environment variable exported, 
1409          which contains the job's size in bytes. Empty jobs
1410          are now denied. This value is now stored in the job
1411          history (but not yet displayed from the web interface)
1412         
1413        - Preliminary work on payments storage : the PostgreSQL 
1414          and LDAP schemas should be OK now, but no code is written
1415          yet to support this functionnality.
1416         
1417    - 1.19alpha16 :
1418   
1419        - the newuser and newgroup LDAP specific directives now accept
1420          a second parameter to attach(), "fail" or "warn". If no entry
1421          is found to attach PyKota attributes to, and "fail" was used,
1422          then action is aborted and program exits in error. If "warn"
1423          is used, a new entry is created but a warning message is logged.
1424         
1425        - The job's originating hostname is now stored in the database,
1426          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
1427       
1428    - 1.19alpha15 :
1429   
1430        - The old pykota filter is now removed. This means that
1431          currently PyKota doesn't support LPRng anymore, but
1432          LPRng support will be re-added, improved, in the near future.
1433         
1434    - 1.19alpha14 :
1435   
1436        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
1437          are now exported as environment variables.
1438         
1439        - Heavy CPU usage is now completely fixed it seems, by
1440          introducing some 0.01 second sleeping when nothing to do.
1441         
1442        - Pre-computation of the job's size is now only
1443          done when enforcement is "STRICT", this saves
1444          CPU for people who don't want to use this new
1445          feature.
1446         
1447        - New 'enforcement' directive which accepts either
1448          STRICT or LAXIST. See sample configuration file
1449          for details.
1450         
1451    - 1.19alpha13 :
1452   
1453        - Get back to an old version of the polling loop which
1454          worked fine, but non-optimally. Will be optimized
1455          as time permits.
1456         
1457    - 1.19alpha12 :
1458   
1459        - Job's size is now precomputed unconditionnally using
1460          the generic PDL analyzer.
1461          NB : This value is not yet used to pre-allow/deny the
1462          job.
1463       
1464    - 1.19alpha11 :
1465   
1466        - The pykota filter is now completely deprecated and
1467          can't be used anymore. LPRng users MUST download
1468          an older version of PyKota. CUPS users MUST use
1469          cupspykota. Better support for LPRng will come
1470          in the near future.
1471         
1472    - 1.19alpha10 :
1473   
1474        - pykotme now uses generic PDL Analyzer directly instead
1475          of spawning a new process.
1476         
1477        - Improvements to generic PDL Analyzer.
1478       
1479        - 25% Speedup in PCL parser. Getting more of the Python version
1480          will probably be difficult, since the completely table driven
1481          parser I wrote is slower than the original algorithm. Then,
1482          the original algorithm is still used for now.
1483          Probable that more speed could be achieved using mmap, at the
1484          expense of severe memory consumption.
1485       
1486        - configuration simplifications : the "accounter" directive's
1487          'hardware' arguments now accepts what was in the "requester"
1488          directive as it's content. The "requester" directive is not
1489          supported anymore. See sample configuration file for details.
1490       
1491    - 1.19alpha9 :
1492       
1493        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1494       
1495        - pykotaOptions LDAP attribute now accepts non-ascii characters
1496          too.
1497         
1498        - First try at cupspykota main loop rewrite
1499       
1500    - 1.19alpha8 :
1501   
1502        - 'querying' accounting method is now called 'hardware'
1503       
1504        - 'external' accounting method is now called 'software'
1505       
1506        - 'stupid' accounting method doesn't exist anymore
1507       
1508        - 'snmp' requester doesn't exist anymore
1509       
1510        - code simplifications in external requester
1511       
1512    - 1.19alpha7 :
1513     
1514        - Database schema change (both LDAP and PostgreSQL) to
1515          allow storage of the job-originating-hostname attribute.
1516          An SQL upgrade script is present. The code is not yet
1517          capable of setting/retrieving this attribute. Support
1518          for this functionnality will be added in the future.
1519         
1520    - 1.19alpha6 :
1521   
1522        - problems connecting to SMTP servers are now catched.
1523       
1524        - pykotme now uses pkpgcounter to compute the size of the
1525          job. This modification adds PCL5 and soon PCLXL (PCL6)
1526          support. You can now get quotes for PCL in addition to
1527          PostScript.
1528         
1529        - pkpgcounter now includes first try at PCLXL parser. 
1530          It is currently disabled until it's finished.
1531         
1532    - 1.19alpha5 :
1533   
1534        - cupspykota polling loop fix for MacOSX (at least)
1535       
1536        - logging subsystem now logs PID too, to ease diagnosing
1537          problems under heavy load.
1538         
1539        - pkpgcounter enhancements.
1540       
1541        - pkprinters --skipexisting now tells pkprinters to not
1542          modify existing printers when --add is used.
1543          pkprinters logs a warning message whenever --add is
1544          used and a printer already exists.
1545         
1546        - LDAP schema now allows accented chars in pykotaFileName
1547          and pykotaTitle attributes.
1548       
1549    - 1.19alpha4 :
1550   
1551        - a bad copy&paste prevented pkpgcounter to work at all, this
1552          is now fixed.
1553         
1554        - improved PCL support in pkpgcounter, with the use of
1555          HP PCL/PJL Reference Set
1556          PCL5 Printer Language Technical Quick Reference Guide
1557       
1558        - pkpgcounter now uses mmap to speed things up : duration
1559          is halved with the sample 87 pages PCL document I use for
1560          testing.
1561         
1562    - 1.19alpha3 :
1563   
1564        - pkprinters now accepts the --list command line argument
1565          to list informations about printers.
1566         
1567    - 1.19alpha2 :
1568   
1569        - pkpgcounter is now included as a smart external
1570          accounter which can handle both PostScript and PCL.
1571         
1572    - 1.19alpha1 :
1573   
1574        - PYKOTALIMITBY environment variable is now exported too.
1575       
1576        - Inclusion of Michele Baldessari's work on autotools.
1577       
1578    - 1.18 :
1579   
1580        - Improved documentation
1581       
1582    - 1.18beta2 :
1583     
1584        - Fix for raw jobs with cupspykota
1585       
1586    - 1.18beta :
1587   
1588        - Small fix for new waitprinter.sh script
1589       
1590        - Better tracebacks on error conditions
1591       
1592        - Improved translations
1593       
1594        - Improved documentation
1595       
1596    - 1.18alpha15 :
1597
1598        - waitprinter.sh replaced by a new and possibly faster
1599          and more powerful one.
1600   
1601        - Names can now begin with a digit.
1602       
1603        - Stability improvement for quotas set on printers groups.
1604       
1605    - 1.18alpha14 :
1606   
1607        - Catches more (all ?) problems with SMTP servers instead
1608          of breaking.
1609         
1610        - Italian translation added.
1611       
1612    - 1.18alpha13 :
1613   
1614        - Pre and Post hooks are now available in the pykota
1615          filter as well.
1616         
1617        - The pykota filter doesn't check last user's quota
1618          anymore when delayed hardware accounting is used :
1619          this will be done anyway the next time the last
1620          user will print again. This saves some database
1621          queries which are unneeded.
1622       
1623    - 1.18alpha12 :
1624   
1625        - Pre and Post hooks to external commands with many
1626          many environment variables available are useable
1627          from the cupspykota backend.
1628          See sample configuration file for details and help.
1629         
1630    - 1.18alpha11 :
1631   
1632        - Hopefully final fix wrt groups (users and printers)
1633       
1634    - 1.18alpha10 :
1635   
1636        - Fixed nested printer groups accounting.
1637       
1638        - Fixed user groups + printer groups problem.
1639       
1640    - 1.18alpha9 :
1641   
1642        - Fix for LDAP problem when job price was 0.
1643       
1644        - Fix for empty user groups with LDAP.
1645       
1646        - Preliminary version of the snmpprinterstatus command added.
1647       
1648    - 1.18alpha8 :
1649   
1650        - Don't retrieve data when not needed.
1651          This avoids many database queries.
1652       
1653    - 1.18alpha7 :
1654   
1655        - New experimental ldapcache directive to improve
1656          LDAP caching.
1657         
1658    - 1.18alpha6 :
1659       
1660        - New configuration directive added : maildomain
1661          to specify the domain to send mail to when user
1662          email address is not set in PyKota database.
1663         
1664        - More complete email message headers. 
1665         
1666    - 1.18alpha5 :
1667   
1668        - Debian packaging specific files, contributed by
1669          Peter Hawkins are now included in the project's tree.
1670         
1671        - Preliminary work on future low-level LDAP caching to speed
1672          up modifications (at least).
1673         
1674    - 1.18alpha4 :
1675   
1676        - Applied some of the modifications suggested by
1677          Peter Hawkins, for better Debian integration.
1678          Most notably cupspykota, pykota, and the shell
1679          scripts are now installed into /usr/share/pykota
1680          instead of into /usr/bin
1681          BEWARE : double check that your symbolic link
1682          to cupspykota is correct, and that your pykota.conf
1683          file use correct path for the shell scripts like
1684          waitprinter.sh and al.
1685         
1686        - pkhint command added, to help in configuring correct
1687          accounting method for PyKota.
1688         
1689    - 1.18alpha3 :
1690   
1691        - Fixed a rare bug in cupspykota backend which gave
1692          incorrect "CUPS backend died abnormally" messages.

1696        - Added the pkprinters command line tool to manage printers
1697          exclusively.
1698       
1699    - 1.18alpha1 :
1700   
1701        - Preliminary work on Relationnal Database Independance.
1702       
1703        - Sample report made from OpenOffice.org added as PDF and SXC.
1704       
1705    - 1.17 :
1706   
1707        - Finalized release.
1708       
1709    - 1.17alpha2 :

1720          to create personnalized reports for PyKota + PostgreSQL.
1721         
1722        - Spanish installation guide for CUPS+PyKota+PostgreSQL
1723          added to the documentation. Doesn't yet document v1.16
1724          though.
1725       
1726        - Portuguese Portuguese translation replaces Brazilian
1727          Portuguese Translation. Brazilian portuguese
1728          translation is still available under the 'br' locale.
1729       
1730    - 1.16beta3 :
1731   
1732        - Swedish translation added.
1733       
1734        - Small fix in documentation.
1735       
1736    - 1.16beta2 :
1737   
1738        - Small fix for job cancelling code while job already
1739          printing in CUPS backend.
1740         
1741        - Big fix wrt printing policies for unknown users. 
1742       
1743    - 1.16beta1 :
1744   
1745        - Manpages upgraded.
1746       
1747    - 1.16alpha26 :
1748   
1749        - Job price is now computed like this :
1750       
1751          SUM((NbPages * PricePerPage) + PricePerJob)
1752         
1753          For current printer and all the printers groups it is
1754          a member of, if any.
1755         
1756          This may be difficult to grasp, but offers unprecedented
1757          flexibility.
1758         
1759    - 1.16alpha25 :
1760   
1761        - Email address can be set at user creation time,

1769       
1770        - Bug wrt number of copies should be fixed.
1771       
1772        - Major code refactoring => It is now possible to
1773          automatically add printers on first print.
1774       
1775    - 1.16alpha23 :
1776   
1777        - Fixed potential accuracy problem if a user printed on
1778          several printers at the very same time.
1779       
1780    - 1.16alpha22 :
1781   
1782        - edpykota now allows adding printers to printer groups
1783       
1784    - 1.16alpha21 :
1785   
1786        - Allows the dot in user and printer names.
1787       
1788        - Printer groups are now cached too.
1789       
1790    - 1.16alpha20 :
1791   
1792        - Fixed several small bugs with the help of PyChecker.
1793       
1794    - 1.16alpha19 :
1795     
1796        - Fixed a bug in PostgreSQL backend's code.
1797       
1798    - 1.16alpha18 :
1799   
1800        - Initial code for printer groups support. Printer groups have
1801          to be added with external tools like psql or gq for example.
1802          Printer groups seems to work fine with users. Untested with user
1803          groups for now.
1804
1805        - Several minor visual problems fixed in reports.
1806       
1807        - Fixed a bug in LDAP date handling.
1808       
1809        - Fix for LDAP problem with some combination of OpenLDAP + Python-LDAP
1810          + some particular settings.
1811         
1812        - mailandpopup.sh shell script added. See sample configuration file
1813          for details.
1814       
1815        - Several environment variables are now exported when executing
1816          external commands (accounters, requesters, mailers) :
1817           
1818            PYKOTAUSERNAME => user who is printing
1819            PYKOTAPRINTERNAME => printer on which the job is being sent
1820            PYKOTATITLE => Job's title
1821            PYKOTAFILENAME => Job's filename
1822            PYKOTACOPIES => number of copies asked
1823            PYKOTAOPTIONS => print command options (-o with CUPS)
1824         
1825    - 1.16alpha17 :
1826   
1827        - Added portugues translation.

1834          have nice looking and useful web based reports (in the future).
1835       
1836        - Added utolower configuration option to convert all usernames
1837          to lowercase during printing.
1838         
1839    - 1.15alpha15 :
1840   
1841        - Now includes the papwaitprinter.sh shell script to wait for
1842          AppleTalk enabled printers.
1843         
1844    - 1.16alpha14 :
1845   
1846        - Now printing on a printer not defined in the Quota Storage,
1847          results in the job being cancelled or stopped, depending
1848          on the printing system.
1849         
1850    - 1.16alpha13 :
1851   
1852        - Small bugfix wrt Python v2.1
1853       
1854        - If username is an empty string, user root is assumed.
1855       
1856        - 'postgresql' is not recognized anymore as a storage backend,
1857          you have to use 'pgstorage' instead. 'postgresql' used to
1858          be supported for compatibility with very old PyKota versions,
1859          this is not the case anymore.
1860         
1861    - 1.16alpha12 :
1862   
1863        - Job price added to job history, to keep accounting correct
1864          if a printer price per page or per job is modified and the
1865          history is not reset : the history would have given a false
1866          amount of money charged before the printer's prices were
1867          modified, this addition solves the problem.
1868         
1869    - 1.16alpha11 :
1870   
1871        - Some preliminary modifications to the database structure for
1872          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1873          database is now provided. LDAP attributes now support
1874          eq, pres and sub indexes.
1875         
1876        - Job history now contains additional informations : 
1877          number of copies, filename, title and print options.
1878         
1879    - 1.16alpha10 :
1880       
1881        - Some modifications done to external policy handling.
1882          See sample configuration file for details.
1883   
1884        - Spanish translation added.
1885       
1886    - 1.16alpha9 :
1887   
1888        - mailto can be set to external(...) to warn users above
1889          quota with any command of your choice (e.g. linpopup).
1890          Several parameters are available, see sample configuration
1891          file for details.
1892         
1893    - 1.16alpha8 :
1894   
1895        - Now cupspykota transmits SIGTERMS to the original 
1896          backend when the user deletes a job being processed.
1897         
1898        - The documentation is now licensed under the terms of the
1899          GNU GPL too.
1900         
1901    - 1.16alpha7 :
1902   
1903        - The CUPS backend is now fully functionnal (it seems).
1904       
1905        - From now on, the use of the pykota filter with CUPS
1906          is deprecated. The pykota filter still has to be
1907          used with LPRng though.
1908       
1909    - 1.16alpha6 :
1910   
1911        - Bug fixed : when edpykota was used to add a printer
1912          with no user or group name, a bad user/group name "*" was
1913          added to the database.
1914         
1915    - 1.16alpha5 :
1916   
1917        - New CUPS backend supports device enumeration !
1918          This means that NO manual CUPS configuration has to
1919          be done. All can now be done from CUPS web interface.
1920       
1921    - 1.16alpha4 :
1922   
1923        - New CUPS backend added.
1924       
1925    - 1.16alpha3 :
1926       
1927        - Minimal FAQ document added.
1928       
1929    - 1.16alpha2 :
1930   
1931        - CGI script now partially supports browser's language preference
1932       
1933    - 1.16alpha1 :
1934   
1935        - Ensures that the LDAP connection is really closed at end.
1936       
1937        - More complete error messages in case of LDAP operation failure.
1938       
1939    - 1.15 :
1940     
1941        - Documentation improved.
1942       
1943    - 1.15beta :
1944   
1945        - Command line tools now accept multiple printer
1946          names or wildcards, separated with commas.
1947         
1948    - 1.15alpha9 :
1949   
1950        - External policy can be used to auto-add unknown users
1951          and any other interesting things you may want to do.
1952          WARNING : You can't auto-add printers for now.
1953          They have to be created manually before.
1954          Look at sample configuration file for examples.
1955         
1956    - 1.15alpha8 :
1957   
1958        - Job history can be disabled if needed.
1959          This feature may be useful for people who use the LDAP
1960          backend and don't want their LDAP tree to grow out of
1961          control.
1962       
1963    - 1.15alpha7 :
1964   
1965        - More work done on caching wrt groups.

1974
1975    - 1.15alpha4 :
1976   
1977        - Problem with Python 2.3 fixed. Needs some definitive
1978          modification.
1979         
1980    - 1.15alpha3 :
1981   
1982        - CGI script now tries to restrict view when the
1983          REMOTE_USER environment variable is set. This allows
1984          people to protect its use with .htaccess files.
1985          When unprotected, or if REMOTE_USER is 'root', then
1986          unrestricted access is granted.
1987          NB : REMOTE_USER is automatically set by the web server
1988          (e.g. Apache) when a page with restricted access is viewed.
1989         
1990    - 1.15alpha2 :
1991   
1992        - Better detection of LPRng.
1993       
1994        - Outputs a warning if printing system is unknown.
1995       
1996    - 1.15alpha1 :
1997   
1998        - Bug fix in SQL code.
1999       
2000    - 1.14 :
2001   
2002        - The PostgreSQL database connection is now always closed before
2003          exit. The LDAP database connection too, but it didn't suffer
2004          from the problem anyway, AFAICT.
2005       
2006    - 1.14beta2 :
2007   
2008        - An LDAP-specific configuration field was introduced, usermail.
2009          Use it to specify which LDAP attribute contains a valid email
2010          address for the user. See sample configuration file for
2011          details.
2012       
2013    - 1.14beta :
2014   
2015        - Two new LDAP-specific configuration fields were introduced,
2016          newuser and newgroup. Use them to specify if you want to add
2017          quota information to existing entries or elsewhere.
2018          See sample configuration file for details.
2019         
2020    - 1.14alpha9 :
2021   
2022        - Documentation improved.
2023       
2024        - pykotme now also prints the user's account balance value
2025          if the user is registered in the Quota Storage and his
2026          limiting factor is "balance".
2027         
2028    - 1.14alpha8 :
2029   
2030        - bin/waitprinter.sh is now included to wait for
2031          SNMP enabled printers to be idle again before
2032          asking for their internal page counter.
2033          See sample configuration file for details.
2034         
2035    - 1.14alpha7 :
2036   
2037        - edpykota now doesn't check if the user/group is above
2038          quota. The check is only done at print time. This
2039          prevents the sending of email messages when creating
2040          user quotas if quota is already reached at creation
2041          time.
2042         
2043    - 1.14alpha6 :
2044   
2045        - Configuration file split and moved to /etc/pykota/pykota.conf
2046          and /etc/pykota/pykotadmin.conf to prevent simple users to
2047          have Read/Write access to the Quota Database.
2048          Don't forget to :
2049         
2050                $ chmod 640 /etc/pykota/pykotadmin.conf
2051               
2052        - storageuser and storageuserpw configuration fields reintroduced
2053          for the same reason.
2054         
2055        - Code cleaning for future implementation of email addresses
2056          support in the PostgreSQL and LDAP backends.
2057         
2058    - 1.14alpha5 :
2059       
2060        - Big bug fixed when changing the prices for a printer
2061       
2062    - 1.14alpha4 :
2063   
2064        - When adding an user, the user itself and its account balance
2065          are now added in the same LDAP entry. Before they were added
2066          as two different LDAP entries.
2067         
2068    - 1.14alpha3 :
2069   
2070        - Email field added to PostgreSQL database. An upgrade script
2071          is included in initscripts/postgresql.
2072       
2073    - 1.14alpha2 :
2074   
2075        - Typo fixed when using the --prototype option to edpykota
2076       
2077    - 1.14alpha1 :
2078   
2079        - Poor man's treshold included : users with a low account
2080          balance (below 1.0 by default, configurable) are sent
2081          a warning message.
2082         
2083        - All warning messages to users are now configurable. 
2084          NB : Warning messages to the administrator are not.
2085       
2086    - 1.13 :
2087   
2088        - Some small fixes wrt group handling.
2089       
2090        - The whole module code was passed through PyChecker and
2091          several small code inconsistencies were fixed,
2092          as well as a bug in the groups code.
2093         
2094    - 1.13alpha1 :
2095   
2096        - Bug fix wrt LDAP.
2097       
2098    - 1.12 :
2099   
2100        - More complete test added in edpykota.
2101       
2102    - 1.12alpha2 :
2103   
2104        - The previous bug fix was incomplete. This is corrected.
2105       
2106    - 1.12alpha1 :
2107   
2108        - Small bug fix.
2109

2111   
2112        - Now includes the pykotme command line tool, to produce
2113          printing quotes for users.
2114         
2115    - 1.10 :
2116   
2117        - Bug fixed wrt quota reports when print limiting is by
2118          account balance.
2119         
2120    - 1.09 :
2121   
2122        - Translations finalized.
2123       
2124        - Manpages updated.
2125       
2126        - Installation documentation improved wrt LDAP support.
2127       
2128    - 1.09beta2 :
2129   
2130        - The CGI script for quota reports works again, and
2131          is much more powerful.
2132       
2133    - 1.09beta :
2134   
2135        - edpykota finalized
2136       
2137    - 1.09alpha2 :
2138   
2139        - LDAP schema modified a bit. Please upgrade.
2140       
2141        - LDAP backend works !
2142       
2143        - repykota and warnpykota allow the root user to pass
2144          users or groups names on the command line. Users
2145          and groups names may contain wildcards.
2146         
2147        - repykota and warnpykota only reports or warns the
2148          current user when launched by non-root users.
2149         
2150        - Minor bug fixes. 
2151   
2152    - 1.09alpha1 :
2153   
2154        - More work on LDAP storage backend. Many options
2155          were added to /etc/pykota.conf to give some
2156          hints to the LDAP storage backend.
2157         
2158        - Severe database access optimizations were done by
2159          rewriting most of the Quota Storage backends drivers.
2160     
2161    - 1.08 :
2162   
2163        - Major bug fix wrt LPRng support for remote jobs.
2164       
2165        - Major bug fix wrt increase/decrease account balances.
2166       
2167    - 1.08alpha8 :
2168   
2169        - Code refactoring.
2170       
2171        - A single user/password pair is used to connect
2172          to the database backend. The storageuser configuration
2173          field, and its associated passwords storageuserpw, are
2174          not used anymore.
2175         
2176        - You can now set PyKota in debug mode, see sample configuration 
2177          file for details.
2178          WARNING : only Quota Storage backend queries are logged in
2179          debug mode, for now.
2180       
2181    - 1.08alpha7 :
2182   
2183        - Very latest LDAP schema.
2184       
2185        - Code enhancement wrt easy pluggability of PyKota attributes
2186          and object classes into an existing LDAP directory.
2187       
2188    - 1.08alpha6 :
2189   
2190        - Minor bug corrections
2191       
2192        - More work on LDAP : new schema
2193       
2194    - 1.08alpha5 :
2195   
2196        - More good work on LDAP storage.
2197          repykota now works reasonably well with the sample LDAP directory.
2198       
2199    - 1.08alpha4 :
2200   
2201        - LDAP schema included.
2202          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2203          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2204          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2205          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2206          MAILING LIST.
2207         
2208    - 1.08alpha3 :
2209   
2210        - External accounting methods were partly rewritten :
2211         
2212          - No more "broken pipe" should happen.
2213         
2214          - They now take care of the number of copies
2215            This may be unneeded though, if the postscript
2216            file already does this, because this would
2217            overcharge users (number of copies counted
2218            two times). NEEDS MORE TESTING.
2219           
2220          - The sample configuration file now contains 
2221            an external accounting method example which should
2222            work with all DSC compliant Postscript files.
2223           
2224        - Some small bugs were fixed.   
2225       
2226    - 1.08alpha2 :
2227   
2228        - Now works with net-snmp v5.0 and above.
2229          It already worked, but the sample configuration
2230          file didn't contain appropriate values...
2231       
2232    - 1.07 : Release of the Shame !
2233   
2234        - The external accounting methods driver was left out of
2235          the CVS tree. Nobody could use it since it wasn't included !
2236         
2237    - 1.06 :
2238   
2239        - Severe bug fixed : if you had a printer in
2240          power saving state which couldn't answer immediately,
2241          a bug was triggered.
2242          It was caused by a bad copy/paste which
2243          forgot to import a Python module at run time.
2244         
2245    - 1.05 :
2246   
2247        - External accounters are finally available !
2248          This means that you can plug any page accounting
2249          method you like by setting the appropriate
2250          'accounter' field in /etc/pykota.conf
2251          See the sample conf/pykota.conf.sample to
2252          learn how to do.
2253         
2254          NB : Both 'external' and 'stupid' accounting methods
2255               account a job size just before *this* job is
2256               sent to the printer.
2257               The original 'querying' method accounts a job
2258               size just before *the next* job is sent to
2259               the printer.
2260       
2261    - 1.05alpha3 :
2262   
2263        - A 'stupid' and unreliable accounting method was
2264          implemented to serve as an example on how to
2265          do this sort of things. This method only counts
2266          the 'showpage' statements in the input data.
2267          See sample configuration file for details.
2268          Pluggable accounting methods work, but I advise
2269          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2270          It is not reliable enough to be used.
2271          Use the 'querying' accounting method instead.
2272         
2273    - 1.05alpha2 :
2274   
2275        - Pluggable accounting methods.
2276       
2277        - Better error handling.
2278       
2279    - 1.05alpha1 :
2280   
2281        - SECURITY file added to help improve PyKota's security.
2282       
2283        - Extracting the printer's internal page counter is now
2284          tried several times, waiting several seconds between
2285          two tries. This lets the time to warm up for some printers
2286          which don't answer when they are sleeping (my Apple
2287          LaserWriter 16/600 PS is in this case, maybe others too)
2288         
2289        - Small display bug fixed in repykota
2290         
2291    - 1.04 :
2292   
2293        - Default print policy for users/groups unknown from
2294          the print quota system is now DENY instead of ALLOW,
2295          since ALLOW can generate inaccurate results
2296          (incorrect job sizes charged to the wrong persons)
2297         
2298        - LPRng support works !
2299       
2300        - A bug was introduced some time ago wrt printers' default
2301          policy for unknown users. It is now corrected.
2302       
2303        - repykota now displays prices per job and per page for each
2304          printer, if they are defined.
2305         
2306        - Minor display bug fixed in repykota.
2307       
2308        - Problem when running repykota with an empty database was fixed.
2309       
2310    - 1.03 :
2311   
2312        - Upgrade script included for earlier versions.
2313          Please look inside the initscripts subdirectory.
2314          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2315         
2316        - repykota now reports account balances too.
2317       
2318        - PyKota now has a nice logo, see the logos
2319          subdirectory.
2320       
2321        - Manual pages were finally updated.
2322       
2323        - Group quotas seem to work now !
2324       
2325        - The new database schema allows to keep an history of all
2326          jobs as well as charge users per page and/or per job,
2327          and track users' account balance.
2328         
2329        - edpykota now accepts much more command line options to 
2330          use the new functionnalities. See edpykota --help for
2331          details.
2332         
2333        - The installation script now allows to install the sample
2334          configuration file during first installation.
2335         
2336        - More group quota code works, but still not finished. 
2337       
2338        - The CGI script displays a link to PyKota's website.
2339       
2340        - The job history is now kept, this will allow per-period
2341          reports in the future.
2342         
2343        - After having modified the quota for an user with edpykota,
2344          a quota check is done to eventually warn the user/admin about
2345          a quota which is too low to print.
2346         
2347        - A workaround is provided for HP Printers : their internal
2348          page counter is only saved to NVRAM in a 10 increment, so
2349          if you switch them off and then on, the reported page counter
2350          may be lower than the real number of pages printed.
2351          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2352          We unconditionnally set the last job's page count to
2353          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2354          in this case.
2355          For a more accurate accounting, never switch your HP printers
2356          off.
2357         
2358        - A fix is provided for printers which only have a volatile 
2359          page counter (reset to 0 every time you switch the printer on)
2360          This should allow PyKota to work reasonably fine with HP Laserjet
2361          4L/5L/6L, not perfect, but better than nothing.
2362          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2363          For a more accurate accounting, never switch your HP printers
2364          off. This is untested, please report any problem.
2365         
2366        - A bug was fixed when edpykota --add was used with users who already
2367          had a quota on the specified printer.
2368         
2369        - A small display bug in repykota was introduced in preliminary
2370          1.03 versions, and fixed later on.
2371         
2372        - Some minor bugs which happened in rare situations were fixed.
2373       
2374        - Support for AppleTalk printers was added, see sample configuration
2375          file for details.
2376         
2377        - Users and group printing can now be controlled (limited) either by 
2378          print quota or by account balance.
2379       
2380    - 1.02 :
2381   
2382        - The installation script now checks for software availability
2383          and in case a software is missing asks the user if he
2384          wants to continue with the installation or abort it.
2385         
2386        - The configuration file pykota.conf is now expected to be
2387          found in /etc instead of in /etc/cups
2388          The installation script prompts the user to see if he
2389          wants to move an old configuration file to the new location
2390          if needed.
2391         
2392        - Improved documentation.

2457              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
2458             
2459        - If no user name is passed at all, then a default wildcard of "*"
2460          which means apply the command on ALL users for this printer is used.

2471       
2472        - If all options are defined globally, there's no need to
2473          define a section for each printer in the configuration
2474          file anymore. Just define a [global] section and it's ok.
