22PyKota NEWS :
23       
24    - 1.24alpha18 (2006-03-15) :
25   
26        - Now uses MIME encapsulation for email messages to avoid
27          some problems with 8 bits messages being rejected.
28         
29    - 1.24alpha17 (2006-03-06) :
30   
31        - Fixed a major problem in the PostgreSQL backend.
32       
33        - pknotify can now check a remote user's name and password.
34       
35    - 1.24alpha16 (2006-03-02) :
36   
37        - Introduced the pknotify command line tool to dialog
38          with remote PyKotIcon applications.
39         
40    - 1.24alpha15 (2006-03-02) :
41       
42        - optimized pkbcodes, pkprinters and pkusers using edpykota as
43          the model.
44       
45        - 'edpykota --list' and 'pkusers --list' are now authorized
46          to mere mortal users, but the list is restricted to informations
47          about the current user.
48       
49        - Extended the functionnality of the 'onbackenderror' directive to
50          allow for configurable retries.
51         
52    - 1.24alpha14 :
53   
54        - Finished optimizations in edpykota and fixed some minor
55          problems with LDAP.
56         
57    - 1.24alpha13 :
58   
59        - Introduced the pkusers command line tool to manage users and 
60          users groups. This command doesn't deal with print quota entries,
61          which continue to be managed through the edpykota command line
62          tool.
63         
64        - Major rewrite and incompatible changes to command line options
65          in edpykota. This command now only deals with print quota
66          entries. Printers, users (or users groups) now have to be created
67          first using pkprinters or pkusers.
68         
69    - 1.24alpha12 :
70   
71        - Introduced the 'duplicatesdelay' directive to specify after
72          which duration two duplicate jobs are not considered duplicate
73          jobs anymore.
74         
75        - Introduced the 'balancezero' directive to specify any value 
76          as the balance limit instead of 0.0. This can allow admins to
77          give a few free credits to users, for example.
78         
79    - 1.24alpha11 :
80   
81        - Huge speed improvements when modifying billing codes and
82          printers.
83       
84        - Both pkbcodes and pkprinters now display the percent done
85          for all actions.
86         
87        - The pkinvoice invoice generator command line utility is now
88          included.
89         
90    - 1.24alpha10 :   
91   
92        - Huge speed improvements when deleting users, printers, and
93          billing codes.
94         
95    - 1.24alpha9 :
96   
97        - Preliminary support for MySQL, thanks to Matt Hyclak.
98       
99    - 1.24alpha8 :
100   
101        - The 'preaccounter' configuration directive was introduced to control
102          which parser to use for precomputation of the job's size. When unset,
103          the internal parser is used just like it was previously. See
104          conf/pykota.conf.sample for more details.
105         
106        - Now subprocesses launched through the overwrite_jobticket directive
107          can also output 'CANCEL', to represent the user's own choice to
108          cancel the print job.
109         
110    - 1.24alpha7 :
111     
112        - pkbanner now handles new print limiting modes correctly.
113       
114        - The cupspykota backend wrapper now accepts to be interrupted
115          with a kill -INT. This causes an immediate and clean abort
116          of the current print job.
117         
118        - Matt Hyclak contributed the possibility to store the printing
119          history in a MySQL database. See the contributed/ directory
120          for details.
121         
122        - Added 2006 to the copyright's years.
123       
124    - 1.24alpha6 :
125   
126        - Fixed internal SNMP and PJL handling code for very fast
127          printers : PyKota didn't see them going from 'idle'
128          to 'printing' to 'idle' again.
129         
130        - Now waitprinter.sh accepts SNMP version number and
131          community name as arguments, thanks to Brandon
132          Holbrook.
133         
134        - Now command line errors and Ctrl+C repectively cause
135          PyKota commands to exit with status -2 and -3.
136         
137    - 1.24alpha5 :
138   
139        - All command line tools now accept -A | --arguments filename.args
140          as a way to bypass the shell's maximal command line size :
141          just put each argument on a line by itself in a file, and
142          pass the file's name as the -A | --arguments command line
143          option's argument. For now this won't be documented in
144          commands' helps.
145         
146        - dumpykota can now dump the complete database in XML
147          format.
148         
149    - 1.24alpha4 :
150   
151        - Added support for the SQLite3 backend.
152          See pykota/initscripts/sqlite/README.sqlite
153       
154    - 1.24alpha3 :
155   
156        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
157          so we regain priviledges before running an external
158          mailto directive.
159       
160    - 1.24alpha2 :
161   
162        - Introduce the "onbackenderror" directive in pykota.conf, to
163          control if the user must be charged or not whenever a real
164          CUPS backend fails. The default value is 'nocharge'.
165          Set it to 'charge' if you think your users can cause a CUPS
166          backend to fail.
167         
168        - Now mark original backends related problems as such in the
169          printing history. Modified printquota.cgi and pykota.css
170          to make them be more visible.
171         
172    - 1.24alpha1 :
173   
174        - Fixed a problem which caused backend errors to be ignored.
175       
176        - The sample LDIF file now contains the two necessary user
177          entries to have an LDAP PyKota Admin and an LDAP PyKota
178          ReadOnly user. The sample configuration files were updated
179          to contain the default passwords used in the LDIF file.
180         
181        - dumpykota is now more strict when checking arguments.   
182       
183    - 1.23 :
184   
185        - Many minor bug fixes and code cleaning.
186       
187        - Improved documentation.
188       
189        - Added Polish translation.
190       
191        - Improved French and Swedish translations.
192       
193    - 1.23beta :
194   
195        - Now the mailto directive is honored in all cases where the job is
196          denied or a warning has to be issued, and the correct reason
197          can be sent back to the user.
198         
199        - The PYKOTAREASON environment variable, if defined, contains the 
200          textual reason why the job was denied or a warning has to be
201          issued.
202       
203    - 1.23alpha31 :
204   
205        - Added support for --maxjobsize, --passthrough and --nopassthrough
206          in pkprinters. These modes are now also honored when printing.
207         
208        - Allows the admin to restrict the number of print queues which will
209          be treated by pkturnkey by passing queues' names as additionnal
210          arguments on pkturnkey's command line.
211         
212        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
213          command line option.   
214         
215    - 1.23alpha30 :
216   
217        - Database changes : you MUST use upgrade-to-1.23.sql again if you
218          use PostgreSQL, or copy the new schema and restart your LDAP
219          server if you use LDAP.
220         
221        - The -C | --comment command line switch was added to edpykota to 
222          attach textual information to modifications done to a user's
223          account balance.
224         
225        - The -l | --limitby command line switch to edpykota was modified 
226          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
227          command's help or manual page for details.
228         
229        - The -i | --ingroups command line switch to repykota allows 
230          PyKota Administrators to only lists members of the specified
231          group or groups (separated with commas).
232         
233        - The -I | --increase command line switch to edpykota allows
234          to increase or decrease page limits.
235         
236        - Added the precomputed job's size and price to the history
237          for controlling purpose.
238       
239    - 1.23alpha29 :
240   
241        - Fixed a small problem with billing codes.
242       
243        - Exports some environment variables earlier, to render the script
244          launched by the overwrite_jobticket directive more powerful.
245         
246        - Now autopykota also creates print quota entries for the user on the
247          printers groups the current printer is a member of.
248         
249    - 1.23alpha28 :
250   
251        - Added users groups management to pkturnkey.
252       
253        - Fixed umask in setup script.
254       
255    - 1.23alpha27 :
256   
257        - Replaced the --dryrun command line option by the --force
258          command line option in pkturnkey, with exactly the opposite
259          effect (for security reasons).
260         
261    - 1.23alpha26 :
262   
263        - Allows parametrized pjl and snmp hardware accounting methods,
264          to be able to respectively set the TCP port and the SNMP

272       
273        - Added a manpage for pkturnkey.
274       
275    - 1.23alpha24 :
276   
277        - Allows different databases to be used depending on the
278          user's rights. This allows PyKota admins to directly
279          use a master LDAP server for read+write, while letting
280          normal users using the replicas for readonly access.
281          NB : using different storage backends is also possible,
282          but you're on your own there.
283         
284    - 1.23alpha23 :
285   
286        - Fixed a problem with banner accounting.
287   
288        - Introduction of the new 'pkturnkey' command line tool.
289       
290    - 1.23alpha22 :

293          It's now much more readable, maintainable, etc...
294         
295        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
296          advised to download earlier releases or purchase the
297          PyKota v1.22HotFix1 Official release. LPRng support
298          MIGHT be re-added later.
299       
300    - 1.23alpha21 :
301     
302        - Fix for IPP requests which contain more than a single
303          job-originating-host-name attribute.
304         
305    - 1.23alpha20 :
306   
307        - Added the overwrite_jobticket directive. See pykota.conf.sample
308          for how to use it.
309         
310    - 1.23alpha19 :
311   
312        - Fixed an LDAP filtering problem when managing billing codes.
313       
314        - Added the unknown_billingcode directive. See pykota.conf.sample
315          for how to use it.
316       
317    - 1.23alpha18 :
318     
319        - Added the dump_bfd.php contribution.
320       
321        - Several fixes in the internal PJL accounter.
322       
323        - Now autopykota doesn't create unneeded print quota entries anymore.
324       
325        - Increased the timeout in the PJL hardware accounting code to
326          accomodate some printers (HP5000 at least).
327         
328    - 1.23alpha17 :
329   
330        - pkpgcounter is now distributed separately only. This
331          means that people must now download and install pkpgcounter
332          v1.56 or higher prior to being able to run PyKota.
333         
334        - Removed all the autoconf/automake stuff which was outdated 
335          and confusing.
336         
337    - 1.23alpha16 :
338     
339        - Extracted the GPL blurb from all commands' help, and use
340          a static version only once. This saves space big time, and
341          eases future translations.
342         
343    - 1.23alpha15 :
344   
345        - pkbcodes now works with the PostgreSQL backend.
346          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
347       
348    - 1.23alpha14 :
349   
350        - Logs a warning when the user/group doesn't exist when running
351          edpykota.
352         
353    - 1.23alpha13 :
354   
355        - Minor fix for user groups because of latest database changes.
356       
357    - 1.23alpha12 :
358

362   
363        - Small fix to the PCL3/4/5 parser for some drivers.
364       
365    - 1.23alpha10 :
366   
367        - Fixed a bad exception name in cupspykota when parsing IPP messages.
368       
369        - Improved the IPP messages module : it can now generate IPP messages
370          in addition to parsing them.
371       
372    - 1.23alpha9 :   
373   
374        - The denyduplicates directive now accepts a command line as an
375          argument beside yes/no. The command is launched and must
376          print either ALLOW or DENY to its standard output. Then the
377          job gets allowed or denied by PyKota.
378          This will allow user interaction in the near future.
379         
380        - Introduced the new 'striptitle' directive to remove ugly prefixes
381          from print job's titles whenever a new print job is submitted.
382         
383        - Fixed internal SNMP accounter for printers which only have a life time
384          page counter, and not a volatile page counter.
385         
386    - 1.23alpha8 :
387   
388        - The data dumper can now summarize payments and history with the
389          help of the --sum command line option (or checkbox in the CGI).
390         
391        - The message used when the job's filename, title and options are
392          hidden because of the privacy directive is now translated at
393          retrieval time, instead of at saving time.
394         
395        - Minor fix in the LDAP backend code. 
396         
397    - 1.23alpha7 :
398   
399        - Improvements to the internal PJL and SNMP accounter : now should
400          support more printers and waste less time.
401         
402    - 1.23alpha6 :
403   
404        - The data dumper's start= and end= date filtering options now
405          accept a positive or negative offset to be added to the special
406          keywords 'yesterday', 'today', 'now', 'tomorrow'.
407          e.g. : dumpykota --data history start=yesterday-5 end=today
408         
409    - 1.23alpha5 :
410   
411        - The data dumper's start= and end= date filtering options now accept
412          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
413         
414    - 1.23alpha4 :
415   
416        - The data dumper now accept start= and end= to specify the starting
417          and ending dates to dump the history.
418         
419    - 1.23alpha3 :
420   
421        - The destination link for the logo used in CGI scripts is
422          configurable.
423         
424        - Data dumper improved : it's faster and now datas are correctly
425          escaped.
426       
427        - The URL to the logo displayed in the CGI scripts is configurable.
428       
429    - 1.23alpha2 :
430   
431        - Fixed edpykota --prototype with balance.
432       
433        - Major rewrite of the IPP message parsing code to definitely
434          fix the job-originating-hostname IPP attribute problem.
435       
436    - 1.23alpha1 :   
437   
438        - Sets current username to the user CUPS runs as instead of "root"
439          when printing test pages from CUPS' web interface (because
440          the username is empty in this case).
441         
442        - Fix for strange values in job-originating-hostname
443       
444    - 1.22 :
445

489       
490    - 1.22alpha5 :
491       
492        - SNMP and PJL improvements with regard to PowerSave / StandBy.
493       
494    - 1.22alpha4 :
495   
496        - Fixed charset problem under MacOSX.
497       
498        - Allows pkbanner to accept more info to display on its
499          command line.
500         
501    - 1.22alpha3 :
502   
503        - Fixes some case related problems with some LDAP backends.
504       
505        - Fixes some problem for printers which directly go from
506          "idle" to "warmup" and never to "printing" before
507          returning to "idle".
508         
509        - Some permissions settings may have prevented cupspykota
510          from parsing cupsd.conf, this is now fixed.
511         
512    - 1.22alpha2 :
513   
514        - Introduction of the web enabled print quote generator.
515       
516        - Fixed a potential race condition when several backend
517          wrappers were present in CUPS' backend directory.
518         
519        - Fixed dumpykota's output in CUPS' page_log format to better
520          match CUPS format.
521         
522    - 1.22alpha1 :
523   
524        - Import into Subversion.
525

547    - 1.21alpha27 :
548   
549        - Allows software() (no arguments) to the software accounting
550          directive. This saves a lot of CPU since the job is not
551          parsed again : the precomputed size is used directly in this
552          case.
553         
554        - epykota's --prototype option now works fine with accounts
555          limited by balance.

566   
567        - The job's size is now always precomputed, even when
568          'enforcement' is not set to 'strict'.
569         
570        - Introduction of the new 'trustjobsize' configuration directive
571          to workaround some problematic printers. See the sample
572          configuration file for details.
573         
574    - 1.21alpha24 :
575   
576        - Big database structure changes. An upgrade script
577          is now included for PostgreSQL. LDAP users may just
578          want to copy the new schema in place.
579         
580        - edpykota now recognizes the -o | --overcharge command line
581          option to set an overcharging or undercharging factor
582          on each print job's cost for a particular user.
583         
584        - repykota's output format has changed an is not limited to 
585          80 characters wide anymore. People who used to parse
586          repykota's output in their own tools are strongly advised
587          to parse dumpykota's output instead.
588         
589        - Introduction of the new 'maxdenybanners' configuration directive
590          to allow up to N (the directive's value) deny banners to be
591          printed even if the print account is forbidden to print.
592         
593        - Better detection of the number of copies in the PostScript parser.
594       
595    - 1.21alpha23 :
596   
597        - Traditional Chinese translation added.
598   
599        - Several fixes and performance improvements with the LDAP backend.
600       
601    - 1.21alpha22 :
602   
603        - edpykota's --delete command line option doesn't consider
604          '*' to be the default argument anymore :-)
605         
606    - 1.21alpha21 :
607   
608        - dumpykota.cgi can now be run as a normal user as opposed to
609          a PyKota administrator. No read access to pykotadmin.conf is
610          necessary anymore. This CGI scripts now honors the REMOTE_USER
611          environment variable just like printquota.cgi does, see
612          the file cgi-bin/README for details.
613          The command line tool dumpykota must still be run by a PyKota
614          administrator.
615         
616        - Fix exception's name error due to a change in recent versions
617          of PygreSQL.   
618

620         
621        - Big bug fix wrt the datelimit field which was never reset.
622         
623    - 1.21alpha19 :
624   
625        - Introduction of the new dumpykota.cgi CGI script, which
626          allows third party tools like phpPrintAnalyzer to be
627          interfaced in real time with PyKota. To use it you
628          may have to change your web server's configuration,
629          please see pykota/cgi-bin/README
630         
631    - 1.21alpha18 :
632   
633        - Now dumpykota can dump the job history into CUPS' page_log
634          format (even when the printing system is LPRng). This allows
635          people to use tools like PrintAnalyzer or phpPrintAnalyzer
636          (two completely different beasts) with PyKota.
637         
638    - 1.21alpha17 :
639     
640        - Fixed field type's name in XML dumps.
641       
642        - Now drops priviledges to user 'pykota' when launched as root
643          (directly or as a CUPS backend), if such an user exists.
644         
645        - Fixed PCL3/4/5 parser for some drivers' output.
646       
647    - 1.21alpha16 :
648

650          thanks to Matt Hyclak.
651         
652    - 1.21alpha15 :
653     
654        - Normalized field names between LDAP and PostgreSQL backends
655          in dumpykota's output.
656         
657        - dumpykota filtering capabilities are now supported within
658          the LDAP backend too.
659         
660    - 1.21alpha14 :
661   
662        - dumpykota now supports extended filtering possibilities
663          with the PostgreSQL backend (LDAP support will come soon).
664         
665    - 1.21alpha13 :
666   
667        - Added a --debug command line option to pkpgcounter, so
668          that people may see what really happens, and what will
669          be available in the future :-)
670         
671    - 1.21alpha12 :
672   
673        - Fixed a bug with non standard pkbanner command lines.
674

676          computed job sizes. **CUPS only for now**
677         
678    - 1.21alpha11 :
679   
680        - Now user and group print quota entries can be stored directly
681          below the user or group with the LDAP backend, using them
682          as branches. Thanks to Stefan Wold for the patch.
683          See the sample configuration file for details.
684         
685        - TLS is now supported with the LDAP backend. Thanks to Stefan
686          Wold for the patch.
687          See the sample configuration file for details.
688         
689        - edpkota now accepts the -U | --used value command line argument
690          to preset the page counters to an initial value. Thanks to
691          Wilson Roberto Afonso and Matt Hyclak for the patch.
692         
693    - 1.21alpha10 :
694   
695        - Now automatically reconnects up to three times if the LDAP server
696          returned an error, possibly due to a timeout.
697         
698    - 1.21alpha9 :
699   
700        - Now searches the configuration files in 'pykota' system user's
701          home directory. The 'pykota' system user and group have
702          to be created by the system administrator, and given
703          sufficient permissions to PyKota's configuration files.
704         
705    - 1.21alpha8 :
706

722        - Improved ESC/P2 miniparser for Stylus Photo printers.
723       
724        - Implemented the --savetoner command line option to pkbanner.
725       
726        - Improved pkbanner's help and messages.
727

729   
730        - Fixed job's data file detection code for LPRng.
731       
732        - Fixed a problem with PJL and PowerSave mode,
733          thanks to Wilson Roberto Afonso.
734       
735    - 1.21alpha3 :
736   
737        - PyKota can now generate its own banners, and either account
738          for them or not, depending on newly introduced directives
739          in pykota.conf
740          Thanks to Matt Hyclak for the patch.
741         
742    - 1.21alpha2 :
743

747         
748    - 1.21alpha1 :
749   
750        - added an IPP messages miniparser. Extraction of the client
751          hostname is now considered to be fiable, at least until
752          the CUPS developpers change something...
753       
754    - 1.20 :
755   
756        - Version number changed.
757       
758    - 1.20beta :
759   
760        - Norwegian (Bokm� preliminary translation added.
761       
762        - German translation was finalized.
763       
764        - Greek translation was finalized.
765       
766        - For urgent legal reasons, a "privacy" directive has been added
767          to pykota.conf, to hide jobs' title, filename and options
768          in the history.
769         
770        - Minor changes in the debian directory.
771       
772    - 1.20alpha27 :
773   
774        - Fixed many problems with translation files. In particular
775          the Brazilian Portuguese translation file was incorrectly
776          installed into the french "breton" locale directory.
777         
778        - Finished French translation. 
779         
780    - 1.20alpha26 :
781   
782        - LPRng support code should now better detect network
783          printers' hostnames or IP addresses.
784         
785        - Fix for recently introduced bug in LPRng support.
786       
787        - Fix for incorrect locale setting when starting.
788       
789    - 1.20alpha25 :
790   
791        - pkprinters allows --list to normal users, but require user
792          to be a PyKota administrator when another command line
793          option is used.
794         
795        - pkhint doesn't use absolute path to search for helper commands
796          anymore.
797         
798        - Spanish translation ready for 1.20.   
799       
800    - 1.20alpha24 :
801   
802        - Now warnpykota only warns users limited by balance once.
803       
804        - Now warnpykota only warns users who have ever printed,
805          to not cause confusion to users who have just opened
806          their account.
807       
808        - Prepared help messages for translations.
809       
810    - 1.20alpha23 :
811   
812        - Add workaround for locale problem.
813       
814    - 1.20alpha22 :
815   
816        - Hopefully final fix for data encoding charset.
817       
818        - edpykota now refuse to work if the user is not a PyKota admin.
819       
820        - Fixes a recently introduced bug with users groups and PostgreSQL.
821       
822    - 1.20alpha21 :
823   
824        - Now dumpykota refuses to launch if the current user is not
825          a PyKota administrator (a PyKota administrator is an user
826          allowed to read the pykotadmin.conf file).
827         
828        - Now any PyKota administrator can use repykota and warnpykota
829          with additionnal arguments, not only the root user.
830         
831        - Improved documentation a bit.
832       
833    - 1.20alpha20 :
834   
835        - Reduced delay in internal SNMP and PJL_over_TCP handlers
836          from 2 to 1 second.

843       
844        - Finished implementation of LDAP support in dumpykota.
845       
846        - The md5 sum of the job's datas is now available as an
847          hexadecimal digest in the PYKOTAMD5SUM environment variable.
848         
849        - The description, filename, title, and options fields
850          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
851          Proper charset is used during extraction from the database.
852         
853    - 1.20alpha18 :
854   
855        - Experimental autopykota command to initialize user
856          account and quota entries on first print while not
857          resetting the balance value if not needed.
858         
859        - Added the new "winbind_separator" directive to strip
860          out the Samba/Winbind domain name while printing if
861          needed (Off by default).
862         
863    - 1.20alpha17 :
864   
865        - Added --hardreset command line option to edpykota.
866

870    - 1.20alpha16 :
871   
872        - Internal handling of socket based PJL queries over
873          port tcp/9100 is now available with the magic
874          'pjl' value in the hardware accounter.
875         
876    - 1.20alpha15 :
877   
878        - LDAP pykotaAccountBalance objects were always created
879          attached to the pykotaUser objects. This is now
880          fixed and the value of balancebase in pykota.conf
881          is now correctly used.
882         
883    - 1.20alpha14 :
884   
885        - Belgian translations added (copy of the french ones).
886       
887        - External hardware accounter now loops until
888          a result can be read correctly.
889         
890        - pkhint now suggest the internal snmp handling instead
891          of the external one.
892         
893    - 1.20alpha13 :
894     
895        - Hardware accounter now accepts the special
896          'snmp' value, meaning ALL is done from main code
897          without launching any subprocess.
898          You need the http://pysnmp.sf.net Python module
899          for this to work (tested with v3.4.2)
900         
901        - Increased delay between two loops iterations 
902          to 2 seconds in waitprinter.sh to diminish
903          CPU load.
904         
905    - 1.20alpha12 :
906   
907        - waitprinter.sh rewritten from scratch to wait
908          for printer status stabilization.
909       
910    - 1.20alpha11 :
911   
912        - Generic data dumper 'dumpykota' introduced.
913          Works only with PostgreSQL backend for now.
914         
915    - 1.20alpha10 :
916   
917        - Added fix for incorrect job's size computation when
918          hardware accounting fails.
919         
920    - 1.20alpha9 :
921   
922        - Small fixes wrt subprocesses.
923       
924    - 1.20alpha8 :
925   
926        - Added full support of PCL3 : HP Deskjet printers are now
927          supported.
928       
929    - 1.20alpha7 :
930   
931        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
932          Needs more work, but no documentation is available.
933       
934    - 1.20alpha6 :
935     
936        - Improved mailandpopup.sh script.
937       
938        - Small fixes for LPRng.
939       
940        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
941          hostname or IP address. Set to 'localhost' when not
942          meaningful.
943         
944        - Fixed issue with how mod_auth_ldap Apache modules
945          fills the REMOTE_USER environment variable.
946         
947        - Fixed a bug in LDAP user deletion code.
948       
949    - 1.20alpha5 :
950     
951        - Introduces the new configuration directive 'onaccountererror'
952          to specify what must be done whenever the software or
953          hardware accounter fails. Allowed values are 'continue' and
954          'stop' (default).
955         
956        - Minor fix in software accounter for a recently introduced
957          problem.
958         
959    - 1.20alpha4 :
960   
961        - Added support for more ghostscript devices in ESC/P2
962          analyzer : stcolor, st800, escp, escpc are now supported.
963         
964    - 1.20alpha3 :
965       
966        - Small improvement in PostScript parser to avoid being
967          fooled by a change in number of copies :
968          The user can't ask for 200 copies of page 1 and 1 copy
969          of page 2 to fool PyKota anymore :
970          this would have been accounted for as 1 copy only, but
971          now the maximum value seen is used.
972         
973        - Relax checks for PCL5 header to accomodate some strange
974          printer drivers.
975         
976        - Now hardware accounting method works like software
977          accounting method wrt the subprocess' output.
978         
979        - Hardware and Software accounting stop the print queue 
980          when the accounting subprocess didn't work. This will
981          be configurable in the near future.
982         
983    - 1.20alpha2 :
984   
985        - Now software accounting method reads accounter's
986          answer until a line with a single integer is
987          obtained or until all of its output has been read.
988          This should fix the problem some people have
989          when strange locale related messages are sent
990          when running subprocesses (Solaris only ?).
991         
992        - First version of ESC/P2 analyzer. Seems to work
993          ok at least with 'epson', 'epsonc', 'eps9mid'
994          and 'esp9high' ghostscript devices. Needs more
995          work to correctly analyze other devices.
996       
997    - 1.20alpha1 :
998   
999        - Fixed problem with number of copies in PCLXL parser.
1000       
1001        - Fixed problem with number of copies in PCL5 parser,
1002          when number of copies was set outside of and before first
1003          page.
1004       
1005        - Added workaround for number of copies directly set in
1006          PostScript code.
1007         
1008        - Added german translation.
1009       
1010        - Fixed problem on first print for user group quota when
1011          "enforcement: strict" is used.
1012       
1013        - Fixed interpolation problem in french translation.
1014       
1015    - 1.19 :
1016   
1017        - Updated existing translations.   
1018       
1019        - Added final Thai and Greek translations.
1020       
1021        - Minor last minute bug fixes.
1022       
1023    - 1.19beta :
1024   
1025        - LPRng support for both software and hardware accounting seems
1026          to be OK.
1027         
1028        - Translation files fixed because of fuzzy matching problem. 
1029       
1030        - Fixed path to Swedish translation: 'sv' instead of 'se'.
1031       
1032        - Added first draft of Thai translation.
1033       
1034        - Fixed some minor bugs with Pychecker.
1035       
1036    - 1.19alpha35 :
1037   
1038        - Generic PDL analyzer now supports Binary PostScript documents
1039          in addition to DSC compliant ones.
1040       
1041    - 1.19alpha34 :
1042   
1043        - LPRng support : software accounting seems to work fine,
1044          but hardware accounting doesn't work yet.
1045   
1046    - 1.19alpha33 :
1047   
1048        - pykosd now accepts command line arguments. Enjoy !
1049          NB : due to a bug in xosd, you need xosd version 2.2.8
1050          or higher if you don't use the default C locale.
1051         
1052    - 1.19alpha32 :
1053   
1054        - Early (not working) version of the LPRng support rewrite.
1055       
1056        - Saner default configuration file.
1057       
1058    - 1.19alpha31 :
1059   
1060        - Fixed a double Python2.1 incompatibility with newer versions,
1061          which prevented the PCL5 and the PCLXL parsers to work with
1062          this older version of Python.
1063         
1064    - 1.19alpha30 :
1065   
1066        - Introduction of preliminary version of the pykosd command
1067       
1068        - Usernames, Groupnames and Printernames can now contain
1069          ANY character, expected '/' and '@'.
1070       
1071        - Integrated most of the Debian work from Sergio
1072          Gonz�z Gonz�z
1073         
1074    - 1.19alpha29 :
1075   
1076        - PCLXL parser should now correctly handle number of
1077          copies set for each page.
1078         
1079        - Added testsuite for generic PDL analyzer.
1080       
1081        - Typo fixed in PCLXL parser.
1082       
1083        - Correctly dispatches error messages depending on the
1084          situation : tools which can be run interactively will
1085          ALWAYS output their logs to stderr, excepted for
1086          their DEBUG messages, for which the "logger:"
1087          directive as set in pykota.conf will be honored.
1088          Tools which can't be run interactively will ALWAYS
1089          honor the "logger:" directive as set in pykota.conf
1090         
1091    - 1.19alpha28 :
1092   
1093        - The description field for printers can now be set,
1094          and is displayed in reports.
1095         
1096        - Fixed a small problem in SQL backend code.
1097         
1098        - Improved pkhint
1099       
1100        - First working PCL6 (aka PCLXL) parser !
1101          Doesn't handle copies yet.
1102       
1103    - 1.19alpha27 :
1104   
1105        - Additionnal 10% speed increase in PCL5 parser for GhostScript
1106          generated files (untested yet with other PCL files).
1107         
1108        - Reintroduced the use of mmap in PCL5 parser : this speedups
1109          PCL5 parsing by almost 4 times.
1110          This 4x with the 3x below give us in fact a twelvefold increase
1111          in performance for PCL5 parsing !
1112         
1113        - The Python accelerator Psyco is now used if available
1114          in the generic PDL parser : it speedups PCL5 parsing by
1115          almost three times automagically.
1116         
1117    - 1.19alpha26 :
1118   
1119        - Fixed PCL5 parser according to the sources of rastertohp.
1120       
1121        - Fixed number of copies handling in PCL5 parser : the number
1122          of copies could vary from page to page.
1123         
1124        - Added more debug information to PCLXL parser. 
1125       
1126    - 1.19alpha25 :
1127   
1128        - Added new "description" field to printers in both
1129          PostgreSQL and LDAP. No code to handle this yet.
1130         
1131        - Reversed the fix for power save mode in printers : 
1132          no paper or tray open would have caused people to
1133          be undercharged.
1134         
1135        - Preliminary version of MySQL initialization script.
1136         
1137    - 1.19alpha24 :
1138   
1139        - Native PDF parsing code now works perfectly with
1140          Python 2.1 and above, and is way faster than before.
1141          GhostScript is not used anymore to convert PDF to PS,
1142          because PDF is parsed directly.
1143         
1144    - 1.19alpha23 :
1145   
1146        - Fixed waitprinter.sh wrt PowerSave mode and some
1147          printers. Thanks to Ryan Suarez.
1148       
1149        - Smart PDL analyzer now recognizes PDF too : two
1150          PDF parsing methods are used : a native one which
1151          is very fast but requires Python 2.3 or above, and
1152          a slower one which uses Ghostscript. PyKota detects
1153          automatically which method to use depending on your
1154          version of Python.
1155       
1156        - All tracebacks now include PyKota's version number.
1157         
1158    - 1.19alpha22 :
1159   
1160        - Ensures that the file pointer for job's data is
1161          reset to the start of the job's datas after the
1162          job's size pre-computation phase.
1163         
1164        - Improved PostScript detection code for bad drivers
1165          which don't correctly switch languages between PJL
1166          and PS.
1167       
1168        - Even better debugging code.
1169       
1170    - 1.19alpha21 :
1171   
1172        - Additionnal check.
1173       
1174    - 1.19alpha20 :
1175   
1176        - More complete logging messages wrt accounters.
1177       
1178        - Now catches early failures occuring when the configuration
1179          files are parsed.
1180       
1181    - 1.19alpha19 :
1182   
1183        - Fixed over-verbose exits when displaying help
1184          or version.
1185         
1186        - Extended some PATH in the shell scripts 
1187       
1188        - Deleting an user now also deletes his payments history.
1189       
1190        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
1191          cause problems.
1192
1193    - 1.19alpha18 :
1194   
1195        - History of payments is now stored in the database, and
1196          updated each time an user's balance is modified with
1197          edpykota --balance. This history represents each time
1198          the user was given some positive or negative credit,
1199          but doesn't reflect price paid for jobs, which appear
1200          in the jobs history instead.
1201         
1202        - Jobs history web reports now include the job's size in
1203          bytes. Also columns were reordered to render the report
1204          more easily readable.
1205         
1206    - 1.19alpha17 :
1207   
1208        - Mysterious bug (program exited unexpectedly without leaving
1209          any log message) which occured once in a while when
1210          cancelling jobs should be fixed now.
1211         
1212        - New 'crashrecipient' directive. Disabled by 
1213          default. See sample configuration file to see how
1214          to activate it. It is suggested that you activate it.
1215         
1216        - New PYKOTAJOBSIZEBYTES environment variable exported, 
1217          which contains the job's size in bytes. Empty jobs
1218          are now denied. This value is now stored in the job
1219          history (but not yet displayed from the web interface)
1220         
1221        - Preliminary work on payments storage : the PostgreSQL 
1222          and LDAP schemas should be OK now, but no code is written
1223          yet to support this functionnality.
1224         
1225    - 1.19alpha16 :
1226   
1227        - the newuser and newgroup LDAP specific directives now accept
1228          a second parameter to attach(), "fail" or "warn". If no entry
1229          is found to attach PyKota attributes to, and "fail" was used,
1230          then action is aborted and program exits in error. If "warn"
1231          is used, a new entry is created but a warning message is logged.
1232         
1233        - The job's originating hostname is now stored in the database,
1234          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
1235       
1236    - 1.19alpha15 :
1237   
1238        - The old pykota filter is now removed. This means that
1239          currently PyKota doesn't support LPRng anymore, but
1240          LPRng support will be re-added, improved, in the near future.
1241         
1242    - 1.19alpha14 :
1243   
1244        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
1245          are now exported as environment variables.
1246         
1247        - Heavy CPU usage is now completely fixed it seems, by
1248          introducing some 0.01 second sleeping when nothing to do.
1249         
1250        - Pre-computation of the job's size is now only
1251          done when enforcement is "STRICT", this saves
1252          CPU for people who don't want to use this new
1253          feature.
1254         
1255        - New 'enforcement' directive which accepts either
1256          STRICT or LAXIST. See sample configuration file
1257          for details.
1258         
1259    - 1.19alpha13 :
1260   
1261        - Get back to an old version of the polling loop which
1262          worked fine, but non-optimally. Will be optimized
1263          as time permits.
1264         
1265    - 1.19alpha12 :
1266   
1267        - Job's size is now precomputed unconditionnally using
1268          the generic PDL analyzer.
1269          NB : This value is not yet used to pre-allow/deny the
1270          job.
1271       
1272    - 1.19alpha11 :
1273   
1274        - The pykota filter is now completely deprecated and
1275          can't be used anymore. LPRng users MUST download
1276          an older version of PyKota. CUPS users MUST use
1277          cupspykota. Better support for LPRng will come
1278          in the near future.
1279         
1280    - 1.19alpha10 :
1281   
1282        - pykotme now uses generic PDL Analyzer directly instead
1283          of spawning a new process.
1284         
1285        - Improvements to generic PDL Analyzer.
1286       
1287        - 25% Speedup in PCL parser. Getting more of the Python version
1288          will probably be difficult, since the completely table driven
1289          parser I wrote is slower than the original algorithm. Then,
1290          the original algorithm is still used for now.
1291          Probable that more speed could be achieved using mmap, at the
1292          expense of severe memory consumption.
1293       
1294        - configuration simplifications : the "accounter" directive's
1295          'hardware' arguments now accepts what was in the "requester"
1296          directive as it's content. The "requester" directive is not
1297          supported anymore. See sample configuration file for details.
1298       
1299    - 1.19alpha9 :
1300       
1301        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1302       
1303        - pykotaOptions LDAP attribute now accepts non-ascii characters
1304          too.
1305         
1306        - First try at cupspykota main loop rewrite
1307       
1308    - 1.19alpha8 :
1309   
1310        - 'querying' accounting method is now called 'hardware'
1311       
1312        - 'external' accounting method is now called 'software'
1313       
1314        - 'stupid' accounting method doesn't exist anymore
1315       
1316        - 'snmp' requester doesn't exist anymore
1317       
1318        - code simplifications in external requester
1319       
1320    - 1.19alpha7 :
1321     
1322        - Database schema change (both LDAP and PostgreSQL) to
1323          allow storage of the job-originating-hostname attribute.
1324          An SQL upgrade script is present. The code is not yet
1325          capable of setting/retrieving this attribute. Support
1326          for this functionnality will be added in the future.
1327         
1328    - 1.19alpha6 :
1329   
1330        - problems connecting to SMTP servers are now catched.
1331       
1332        - pykotme now uses pkpgcounter to compute the size of the
1333          job. This modification adds PCL5 and soon PCLXL (PCL6)
1334          support. You can now get quotes for PCL in addition to
1335          PostScript.
1336         
1337        - pkpgcounter now includes first try at PCLXL parser. 
1338          It is currently disabled until it's finished.
1339         
1340    - 1.19alpha5 :
1341   
1342        - cupspykota polling loop fix for MacOSX (at least)
1343       
1344        - logging subsystem now logs PID too, to ease diagnosing
1345          problems under heavy load.
1346         
1347        - pkpgcounter enhancements.
1348       
1349        - pkprinters --skipexisting now tells pkprinters to not
1350          modify existing printers when --add is used.
1351          pkprinters logs a warning message whenever --add is
1352          used and a printer already exists.
1353         
1354        - LDAP schema now allows accented chars in pykotaFileName
1355          and pykotaTitle attributes.
1356       
1357    - 1.19alpha4 :
1358   
1359        - a bad copy&paste prevented pkpgcounter to work at all, this
1360          is now fixed.
1361         
1362        - improved PCL support in pkpgcounter, with the use of
1363          HP PCL/PJL Reference Set
1364          PCL5 Printer Language Technical Quick Reference Guide
1365       
1366        - pkpgcounter now uses mmap to speed things up : duration
1367          is halved with the sample 87 pages PCL document I use for
1368          testing.
1369         
1370    - 1.19alpha3 :
1371   
1372        - pkprinters now accepts the --list command line argument
1373          to list informations about printers.
1374         
1375    - 1.19alpha2 :
1376   
1377        - pkpgcounter is now included as a smart external
1378          accounter which can handle both PostScript and PCL.
1379         
1380    - 1.19alpha1 :
1381   
1382        - PYKOTALIMITBY environment variable is now exported too.
1383       
1384        - Inclusion of Michele Baldessari's work on autotools.
1385       
1386    - 1.18 :
1387   
1388        - Improved documentation
1389       
1390    - 1.18beta2 :
1391     
1392        - Fix for raw jobs with cupspykota
1393       
1394    - 1.18beta :
1395   
1396        - Small fix for new waitprinter.sh script
1397       
1398        - Better tracebacks on error conditions
1399       
1400        - Improved translations
1401       
1402        - Improved documentation
1403       
1404    - 1.18alpha15 :
1405
1406        - waitprinter.sh replaced by a new and possibly faster
1407          and more powerful one.
1408   
1409        - Names can now begin with a digit.
1410       
1411        - Stability improvement for quotas set on printers groups.
1412       
1413    - 1.18alpha14 :
1414   
1415        - Catches more (all ?) problems with SMTP servers instead
1416          of breaking.
1417         
1418        - Italian translation added.
1419       
1420    - 1.18alpha13 :
1421   
1422        - Pre and Post hooks are now available in the pykota
1423          filter as well.
1424         
1425        - The pykota filter doesn't check last user's quota
1426          anymore when delayed hardware accounting is used :
1427          this will be done anyway the next time the last
1428          user will print again. This saves some database
1429          queries which are unneeded.
1430       
1431    - 1.18alpha12 :
1432   
1433        - Pre and Post hooks to external commands with many
1434          many environment variables available are useable
1435          from the cupspykota backend.
1436          See sample configuration file for details and help.
1437         
1438    - 1.18alpha11 :
1439   
1440        - Hopefully final fix wrt groups (users and printers)
1441       
1442    - 1.18alpha10 :
1443   
1444        - Fixed nested printer groups accounting.
1445       
1446        - Fixed user groups + printer groups problem.
1447       
1448    - 1.18alpha9 :
1449   
1450        - Fix for LDAP problem when job price was 0.
1451       
1452        - Fix for empty user groups with LDAP.
1453       
1454        - Preliminary version of the snmpprinterstatus command added.
1455       
1456    - 1.18alpha8 :
1457   
1458        - Don't retrieve data when not needed.

1479        - Preliminary work on future low-level LDAP caching to speed
1480          up modifications (at least).
1481         
1482    - 1.18alpha4 :
1483   
1484        - Applied some of the modifications suggested by
1485          Peter Hawkins, for better Debian integration.
1486          Most notably cupspykota, pykota, and the shell
1487          scripts are now installed into /usr/share/pykota
1488          instead of into /usr/bin
1489          BEWARE : double check that your symbolic link
1490          to cupspykota is correct, and that your pykota.conf
1491          file use correct path for the shell scripts like
1492          waitprinter.sh and al.

1532          though.
1533       
1534        - Portuguese Portuguese translation replaces Brazilian
1535          Portuguese Translation. Brazilian portuguese
1536          translation is still available under the 'br' locale.
1537       
1538    - 1.16beta3 :

1547          printing in CUPS backend.
1548         
1549        - Big fix wrt printing policies for unknown users. 
1550       
1551    - 1.16beta1 :
1552   
1553        - Manpages upgraded.

1558       
1559          SUM((NbPages * PricePerPage) + PricePerJob)
1560         
1561          For current printer and all the printers groups it is
1562          a member of, if any.
1563         
1564          This may be difficult to grasp, but offers unprecedented
1565          flexibility.

1605       
1606    - 1.16alpha18 :
1607   
1608        - Initial code for printer groups support. Printer groups have
1609          to be added with external tools like psql or gq for example.
1610          Printer groups seems to work fine with users. Untested with user
1611          groups for now.
1612
1613        - Several minor visual problems fixed in reports.
1614       
1615        - Fixed a bug in LDAP date handling.

1621          for details.
1622       
1623        - Several environment variables are now exported when executing
1624          external commands (accounters, requesters, mailers) :
1625           
1626            PYKOTAUSERNAME => user who is printing
1627            PYKOTAPRINTERNAME => printer on which the job is being sent
1628            PYKOTATITLE => Job's title
1629            PYKOTAFILENAME => Job's filename
1630            PYKOTACOPIES => number of copies asked
1631            PYKOTAOPTIONS => print command options (-o with CUPS)
1632         
1633    - 1.16alpha17 :
1634   
1635        - Added portugues translation.

1642          have nice looking and useful web based reports (in the future).
1643       
1644        - Added utolower configuration option to convert all usernames
1645          to lowercase during printing.

1652    - 1.16alpha14 :
1653   
1654        - Now printing on a printer not defined in the Quota Storage,
1655          results in the job being cancelled or stopped, depending
1656          on the printing system.
1657         
1658    - 1.16alpha13 :
1659   
1660        - Small bugfix wrt Python v2.1
1661       
1662        - If username is an empty string, user root is assumed.
1663       
1664        - 'postgresql' is not recognized anymore as a storage backend,
1665          you have to use 'pgstorage' instead. 'postgresql' used to
1666          be supported for compatibility with very old PyKota versions,
1667          this is not the case anymore.
1668         
1669    - 1.16alpha12 :
1670   
1671        - Job price added to job history, to keep accounting correct
1672          if a printer price per page or per job is modified and the
1673          history is not reset : the history would have given a false
1674          amount of money charged before the printer's prices were
1675          modified, this addition solves the problem.
1676         
1677    - 1.16alpha11 :
1678   
1679        - Some preliminary modifications to the database structure for
1680          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1681          database is now provided. LDAP attributes now support
1682          eq, pres and sub indexes.
1683         
1684        - Job history now contains additional informations : 
1685          number of copies, filename, title and print options.
1686         
1687    - 1.16alpha10 :
1688       
1689        - Some modifications done to external policy handling.
1690          See sample configuration file for details.
1691   
1692        - Spanish translation added.
1693       
1694    - 1.16alpha9 :
1695   
1696        - mailto can be set to external(...) to warn users above
1697          quota with any command of your choice (e.g. linpopup).
1698          Several parameters are available, see sample configuration
1699          file for details.
1700         
1701    - 1.16alpha8 :
1702   
1703        - Now cupspykota transmits SIGTERMS to the original 
1704          backend when the user deletes a job being processed.
1705         
1706        - The documentation is now licensed under the terms of the
1707          GNU GPL too.
1708         
1709    - 1.16alpha7 :

1711        - The CUPS backend is now fully functionnal (it seems).
1712       
1713        - From now on, the use of the pykota filter with CUPS
1714          is deprecated. The pykota filter still has to be
1715          used with LPRng though.
1716       
1717    - 1.16alpha6 :
1718   
1719        - Bug fixed : when edpykota was used to add a printer
1720          with no user or group name, a bad user/group name "*" was
1721          added to the database.
1722         
1723    - 1.16alpha5 :
1724   
1725        - New CUPS backend supports device enumeration !
1726          This means that NO manual CUPS configuration has to
1727          be done. All can now be done from CUPS web interface.
1728       
1729    - 1.16alpha4 :
1730   
1731        - New CUPS backend added.
1732       
1733    - 1.16alpha3 :

1754          names or wildcards, separated with commas.
1755         
1756    - 1.15alpha9 :
1757   
1758        - External policy can be used to auto-add unknown users
1759          and any other interesting things you may want to do.
1760          WARNING : You can't auto-add printers for now.
1761          They have to be created manually before.
1762          Look at sample configuration file for examples.
1763         
1764    - 1.15alpha8 :
1765   
1766        - Job history can be disabled if needed.
1767          This feature may be useful for people who use the LDAP
1768          backend and don't want their LDAP tree to grow out of
1769          control.
1770       
1771    - 1.15alpha7 :
1772   
1773        - More work done on caching wrt groups.

1782
1783    - 1.15alpha4 :
1784   
1785        - Problem with Python 2.3 fixed. Needs some definitive
1786          modification.
1787         
1788    - 1.15alpha3 :
1789   
1790        - CGI script now tries to restrict view when the
1791          REMOTE_USER environment variable is set. This allows
1792          people to protect its use with .htaccess files.
1793          When unprotected, or if REMOTE_USER is 'root', then
1794          unrestricted access is granted.
1795          NB : REMOTE_USER is automatically set by the web server
1796          (e.g. Apache) when a page with restricted access is viewed.
1797         
1798    - 1.15alpha2 :
1799

1803       
1804    - 1.15alpha1 :
1805   
1806        - Bug fix in SQL code.
1807       
1808    - 1.14 :
1809   
1810        - The PostgreSQL database connection is now always closed before
1811          exit. The LDAP database connection too, but it didn't suffer
1812          from the problem anyway, AFAICT.
1813       
1814    - 1.14beta2 :
1815   
1816        - An LDAP-specific configuration field was introduced, usermail.
1817          Use it to specify which LDAP attribute contains a valid email
1818          address for the user. See sample configuration file for
1819          details.
1820       
1821    - 1.14beta :
1822   
1823        - Two new LDAP-specific configuration fields were introduced,
1824          newuser and newgroup. Use them to specify if you want to add
1825          quota information to existing entries or elsewhere.
1826          See sample configuration file for details.
1827         
1828    - 1.14alpha9 :
1829   
1830        - Documentation improved.
1831       
1832        - pykotme now also prints the user's account balance value
1833          if the user is registered in the Quota Storage and his
1834          limiting factor is "balance".
1835         
1836    - 1.14alpha8 :
1837   
1838        - bin/waitprinter.sh is now included to wait for
1839          SNMP enabled printers to be idle again before
1840          asking for their internal page counter.
1841          See sample configuration file for details.
1842         
1843    - 1.14alpha7 :
1844   
1845        - edpykota now doesn't check if the user/group is above
1846          quota. The check is only done at print time. This
1847          prevents the sending of email messages when creating
1848          user quotas if quota is already reached at creation
1849          time.
1850         
1851    - 1.14alpha6 :
1852   
1853        - Configuration file split and moved to /etc/pykota/pykota.conf
1854          and /etc/pykota/pykotadmin.conf to prevent simple users to
1855          have Read/Write access to the Quota Database.
1856          Don't forget to :
1857         
1858                $ chmod 640 /etc/pykota/pykotadmin.conf
1859               
1860        - storageuser and storageuserpw configuration fields reintroduced
1861          for the same reason.
1862         
1863        - Code cleaning for future implementation of email addresses
1864          support in the PostgreSQL and LDAP backends.
1865         
1866    - 1.14alpha5 :
1867       
1868        - Big bug fixed when changing the prices for a printer
1869       
1870    - 1.14alpha4 :
1871   
1872        - When adding an user, the user itself and its account balance
1873          are now added in the same LDAP entry. Before they were added
1874          as two different LDAP entries.
1875         
1876    - 1.14alpha3 :
1877   
1878        - Email field added to PostgreSQL database. An upgrade script

1888          balance (below 1.0 by default, configurable) are sent
1889          a warning message.
1890         
1891        - All warning messages to users are now configurable. 
1892          NB : Warning messages to the administrator are not.

1895   
1896        - Some small fixes wrt group handling.
1897       
1898        - The whole module code was passed through PyChecker and
1899          several small code inconsistencies were fixed,
1900          as well as a bug in the groups code.

1951        - repykota and warnpykota allow the root user to pass
1952          users or groups names on the command line. Users
1953          and groups names may contain wildcards.
1954         
1955        - repykota and warnpykota only reports or warns the
1956          current user when launched by non-root users.
1957         
1958        - Minor bug fixes. 
1959   
1960    - 1.09alpha1 :
1961   
1962        - More work on LDAP storage backend. Many options
1963          were added to /etc/pykota.conf to give some
1964          hints to the LDAP storage backend.
1965         
1966        - Severe database access optimizations were done by
1967          rewriting most of the Quota Storage backends drivers.
1968     
1969    - 1.08 :
1970   
1971        - Major bug fix wrt LPRng support for remote jobs.
1972       
1973        - Major bug fix wrt increase/decrease account balances.
1974       
1975    - 1.08alpha8 :
1976   
1977        - Code refactoring.
1978       
1979        - A single user/password pair is used to connect
1980          to the database backend. The storageuser configuration
1981          field, and its associated passwords storageuserpw, are
1982          not used anymore.
1983         
1984        - You can now set PyKota in debug mode, see sample configuration 
1985          file for details.
1986          WARNING : only Quota Storage backend queries are logged in
1987          debug mode, for now.
1988       
1989    - 1.08alpha7 :
1990   
1991        - Very latest LDAP schema.
1992       
1993        - Code enhancement wrt easy pluggability of PyKota attributes
1994          and object classes into an existing LDAP directory.
1995       
1996    - 1.08alpha6 :
1997   
1998        - Minor bug corrections
1999       
2000        - More work on LDAP : new schema
2001       
2002    - 1.08alpha5 :
2003   
2004        - More good work on LDAP storage.
2005          repykota now works reasonably well with the sample LDAP directory.
2006       
2007    - 1.08alpha4 :
2008   
2009        - LDAP schema included.
2010          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2011          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2012          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2013          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2014          MAILING LIST.
2015         
2016    - 1.08alpha3 :
2017   
2018        - External accounting methods were partly rewritten :
2019         
2020          - No more "broken pipe" should happen.
2021         
2022          - They now take care of the number of copies
2023            This may be unneeded though, if the postscript
2024            file already does this, because this would
2025            overcharge users (number of copies counted
2026            two times). NEEDS MORE TESTING.
2027           
2028          - The sample configuration file now contains 
2029            an external accounting method example which should
2030            work with all DSC compliant Postscript files.
2031           
2032        - Some small bugs were fixed.   
2033       
2034    - 1.08alpha2 :
2035   
2036        - Now works with net-snmp v5.0 and above.
2037          It already worked, but the sample configuration
2038          file didn't contain appropriate values...
2039       
2040    - 1.07 : Release of the Shame !
2041   
2042        - The external accounting methods driver was left out of
2043          the CVS tree. Nobody could use it since it wasn't included !
2044         
2045    - 1.06 :
2046   
2047        - Severe bug fixed : if you had a printer in
2048          power saving state which couldn't answer immediately,
2049          a bug was triggered.
2050          It was caused by a bad copy/paste which
2051          forgot to import a Python module at run time.
2052         
2053    - 1.05 :
2054   
2055        - External accounters are finally available !
2056          This means that you can plug any page accounting
2057          method you like by setting the appropriate
2058          'accounter' field in /etc/pykota.conf
2059          See the sample conf/pykota.conf.sample to
2060          learn how to do.
2061         
2062          NB : Both 'external' and 'stupid' accounting methods
2063               account a job size just before *this* job is
2064               sent to the printer.
2065               The original 'querying' method accounts a job
2066               size just before *the next* job is sent to
2067               the printer.
2068       
2069    - 1.05alpha3 :
2070   
2071        - A 'stupid' and unreliable accounting method was
2072          implemented to serve as an example on how to
2073          do this sort of things. This method only counts
2074          the 'showpage' statements in the input data.
2075          See sample configuration file for details.
2076          Pluggable accounting methods work, but I advise
2077          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2078          It is not reliable enough to be used.
2079          Use the 'querying' accounting method instead.
2080         
2081    - 1.05alpha2 :
2082   
2083        - Pluggable accounting methods.
2084       
2085        - Better error handling.
2086       
2087    - 1.05alpha1 :
2088   
2089        - SECURITY file added to help improve PyKota's security.
2090       
2091        - Extracting the printer's internal page counter is now
2092          tried several times, waiting several seconds between
2093          two tries. This lets the time to warm up for some printers
2094          which don't answer when they are sleeping (my Apple
2095          LaserWriter 16/600 PS is in this case, maybe others too)
2096         
2097        - Small display bug fixed in repykota
2098         
2099    - 1.04 :
2100   
2101        - Default print policy for users/groups unknown from
2102          the print quota system is now DENY instead of ALLOW,
2103          since ALLOW can generate inaccurate results
2104          (incorrect job sizes charged to the wrong persons)
2105         
2106        - LPRng support works !
2107       
2108        - A bug was introduced some time ago wrt printers' default
2109          policy for unknown users. It is now corrected.
2110       
2111        - repykota now displays prices per job and per page for each
2112          printer, if they are defined.
2113         
2114        - Minor display bug fixed in repykota.
2115       
2116        - Problem when running repykota with an empty database was fixed.
2117       
2118    - 1.03 :
2119   
2120        - Upgrade script included for earlier versions.
2121          Please look inside the initscripts subdirectory.
2122          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2123         
2124        - repykota now reports account balances too.
2125       
2126        - PyKota now has a nice logo, see the logos
2127          subdirectory.
2128       
2129        - Manual pages were finally updated.
2130       
2131        - Group quotas seem to work now !
2132       
2133        - The new database schema allows to keep an history of all
2134          jobs as well as charge users per page and/or per job,
2135          and track users' account balance.
2136         
2137        - edpykota now accepts much more command line options to 
2138          use the new functionnalities. See edpykota --help for
2139          details.
2140         
2141        - The installation script now allows to install the sample
2142          configuration file during first installation.
2143         
2144        - More group quota code works, but still not finished. 
2145       
2146        - The CGI script displays a link to PyKota's website.
2147       
2148        - The job history is now kept, this will allow per-period
2149          reports in the future.
2150         
2151        - After having modified the quota for an user with edpykota,
2152          a quota check is done to eventually warn the user/admin about
2153          a quota which is too low to print.
2154         
2155        - A workaround is provided for HP Printers : their internal
2156          page counter is only saved to NVRAM in a 10 increment, so
2157          if you switch them off and then on, the reported page counter
2158          may be lower than the real number of pages printed.
2159          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2160          We unconditionnally set the last job's page count to
2161          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2162          in this case.
2163          For a more accurate accounting, never switch your HP printers
2164          off.
2165         
2166        - A fix is provided for printers which only have a volatile 
2167          page counter (reset to 0 every time you switch the printer on)
2168          This should allow PyKota to work reasonably fine with HP Laserjet
2169          4L/5L/6L, not perfect, but better than nothing.
2170          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2171          For a more accurate accounting, never switch your HP printers
2172          off. This is untested, please report any problem.
2173         
2174        - A bug was fixed when edpykota --add was used with users who already
2175          had a quota on the specified printer.
2176         
2177        - A small display bug in repykota was introduced in preliminary
2178          1.03 versions, and fixed later on.
2179         
2180        - Some minor bugs which happened in rare situations were fixed.
2181       
2182        - Support for AppleTalk printers was added, see sample configuration
2183          file for details.
2184         
2185        - Users and group printing can now be controlled (limited) either by 
2186          print quota or by account balance.
2187       
2188    - 1.02 :
2189   
2190        - The installation script now checks for software availability
2191          and in case a software is missing asks the user if he
2192          wants to continue with the installation or abort it.
2193         
2194        - The configuration file pykota.conf is now expected to be
2195          found in /etc instead of in /etc/cups
2196          The installation script prompts the user to see if he
2197          wants to move an old configuration file to the new location
2198          if needed.
2199         
2200        - Improved documentation.
2201       
2202        - You can now set the tcp/ip port on which the Quota Storage
2203          Server is listening, see sample configuration file for details.
2204       
2205        - Better general error handling.
2206       
2207        - Upgrade script for pre 1.01 PostgreSQL database schema is now
2208          included as well.
2209       
2210    - 1.01 :
2211   
2212        - The configuration file now accepts an option   
2213          to choose the recipient(s) of the email messages :
2214         
2215            - DevNull means no one will receive them.
2216            - User means only the user will receive them.
2217            - Admin means only the admin will receive them.
2218            - Both means the User and the Admin will receive them.
2219           
2220        - The configuration file now uses hard-coded default values
2221          when an option is not set. See sample configuration file
2222          for details.
2223         
2224        - Manual pages are included since 1.00, but I forgot to   
2225          add this information to this file.
2226         
2227        - Redistribution terms for the official package have 
2228          softened and are now fully GPL compatible :
2229          unrestricted modification is now allowed even for
2230          the version number.
2231         
2232    - 1.00 :
2233   
2234        - edpykota now accepts a --noquota option. This
2235          disable quota checking while still doing page
2236          accounting. This is really useful for people
2237          who don't want to limit their users but want
2238          to know how much pages they print.
2239         
2240        - Some untested scripts were added to retrieve
2241          the life time page counter of non-SNMP printers.
2242         
2243        - Every directory now has a specific README file. 
2244       
2245    - 0.99 :
2246   
2247        - Under some circumstances while the user wasn't allowed
2248          to print, he didn't receive any email message. It is
2249          now fixed.
2250         
2251        - When an user wasn't allowed to print, the quota for
2252          the previous user wasn't updated. This is now fixed.
2253         
2254    - 0.98 :
2255   
2256        - Correctly handle the case where the printer is switched off.
2257       
2258        - Small bug wrt syslog fixed.
2259       
2260    - 0.97 :
2261   
2262        - edpykota accepts wildcards on its command line for users/groups too
2263          if the --add option is not set, e.g. :
2264         
2265              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
2266             
2267        - If no user name is passed at all, then a default wildcard of "*"
2268          which means apply the command on ALL users for this printer is used.
2269         
2270        - Small bug fixes.
2271       
2272    - 0.96 :
2273
2274        - Options requester, policy, admin, adminmail and gracedelay can now
2275          be set either globally or per printer. The printer option has
2276          priority if both are defined.
2277
2278        - More powerful configuration parser.
2279       
2280        - If all options are defined globally, there's no need to
2281          define a section for each printer in the configuration
2282          file anymore. Just define a [global] section and it's ok.
2283
2284    - 0.95 :
2285
2286        - External requesters for printers finally added.
2287
2288        - Full internationalization (english and french are supported)
2289 
2290        - More complete quota usage report
2291
2292        - CGI script to access to the quota usage report
2293
2294        - Several bugs fixed.
2295
2296
2297    - 0.9 :
2298
2299        - First public version
