22PyKota NEWS :
23       
24    - 1.25alpha1 (2006-04-10) :
25   
26        - Ensures that the denied banners counter is properly initialized
27          with relationnal databases.
28         
29    - 1.24 (2006-04-08) :
30   
31        - Improved documentation and packaging stuff.
32       
33    - 1.24beta (2006-03-26) :
34   
35        - Finalized the pknotify command.
36       
37        - Updated the messages catalogs for translations.
38       
39    - 1.24alpha18 (2006-03-15) :
40   
41        - Now uses MIME encapsulation for email messages to avoid
42          some problems with 8 bits messages being rejected.
43         
44    - 1.24alpha17 (2006-03-06) :
45   
46        - Fixed a major problem in the PostgreSQL backend.
47       
48        - pknotify can now check a remote user's name and password.
49       
50    - 1.24alpha16 (2006-03-02) :
51   
52        - Introduced the pknotify command line tool to dialog
53          with remote PyKotIcon applications.
54         
55    - 1.24alpha15 (2006-03-02) :
56       
57        - optimized pkbcodes, pkprinters and pkusers using edpykota as
58          the model.
59       
60        - 'edpykota --list' and 'pkusers --list' are now authorized
61          to mere mortal users, but the list is restricted to informations
62          about the current user.
63       
64        - Extended the functionnality of the 'onbackenderror' directive to
65          allow for configurable retries.
66         
67    - 1.24alpha14 :
68   
69        - Finished optimizations in edpykota and fixed some minor
70          problems with LDAP.
71         
72    - 1.24alpha13 :
73   
74        - Introduced the pkusers command line tool to manage users and 
75          users groups. This command doesn't deal with print quota entries,
76          which continue to be managed through the edpykota command line
77          tool.
78         
79        - Major rewrite and incompatible changes to command line options
80          in edpykota. This command now only deals with print quota
81          entries. Printers, users (or users groups) now have to be created
82          first using pkprinters or pkusers.
83         
84    - 1.24alpha12 :
85   
86        - Introduced the 'duplicatesdelay' directive to specify after
87          which duration two duplicate jobs are not considered duplicate
88          jobs anymore.
89         
90        - Introduced the 'balancezero' directive to specify any value 
91          as the balance limit instead of 0.0. This can allow admins to
92          give a few free credits to users, for example.
93         
94    - 1.24alpha11 :
95   
96        - Huge speed improvements when modifying billing codes and
97          printers.
98       
99        - Both pkbcodes and pkprinters now display the percent done
100          for all actions.
101         
102        - The pkinvoice invoice generator command line utility is now
103          included.
104         
105    - 1.24alpha10 :   
106   
107        - Huge speed improvements when deleting users, printers, and
108          billing codes.
109         
110    - 1.24alpha9 :
111   
112        - Preliminary support for MySQL, thanks to Matt Hyclak.
113       
114    - 1.24alpha8 :
115   
116        - The 'preaccounter' configuration directive was introduced to control
117          which parser to use for precomputation of the job's size. When unset,
118          the internal parser is used just like it was previously. See
119          conf/pykota.conf.sample for more details.
120         
121        - Now subprocesses launched through the overwrite_jobticket directive
122          can also output 'CANCEL', to represent the user's own choice to
123          cancel the print job.
124         
125    - 1.24alpha7 :
126     
127        - pkbanner now handles new print limiting modes correctly.
128       
129        - The cupspykota backend wrapper now accepts to be interrupted
130          with a kill -INT. This causes an immediate and clean abort
131          of the current print job.
132         
133        - Matt Hyclak contributed the possibility to store the printing
134          history in a MySQL database. See the contributed/ directory
135          for details.
136         
137        - Added 2006 to the copyright's years.
138       
139    - 1.24alpha6 :
140   
141        - Fixed internal SNMP and PJL handling code for very fast
142          printers : PyKota didn't see them going from 'idle'
143          to 'printing' to 'idle' again.
144         
145        - Now waitprinter.sh accepts SNMP version number and
146          community name as arguments, thanks to Brandon
147          Holbrook.
148         
149        - Now command line errors and Ctrl+C repectively cause
150          PyKota commands to exit with status -2 and -3.
151         
152    - 1.24alpha5 :
153   
154        - All command line tools now accept -A | --arguments filename.args
155          as a way to bypass the shell's maximal command line size :
156          just put each argument on a line by itself in a file, and
157          pass the file's name as the -A | --arguments command line
158          option's argument. For now this won't be documented in
159          commands' helps.
160         
161        - dumpykota can now dump the complete database in XML
162          format.
163         
164    - 1.24alpha4 :
165   
166        - Added support for the SQLite3 backend.
167          See pykota/initscripts/sqlite/README.sqlite
168       
169    - 1.24alpha3 :
170   
171        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
172          so we regain priviledges before running an external
173          mailto directive.
174       
175    - 1.24alpha2 :
176   
177        - Introduce the "onbackenderror" directive in pykota.conf, to
178          control if the user must be charged or not whenever a real
179          CUPS backend fails. The default value is 'nocharge'.
180          Set it to 'charge' if you think your users can cause a CUPS
181          backend to fail.
182         
183        - Now mark original backends related problems as such in the
184          printing history. Modified printquota.cgi and pykota.css
185          to make them be more visible.
186         
187    - 1.24alpha1 :
188   
189        - Fixed a problem which caused backend errors to be ignored.
190       
191        - The sample LDIF file now contains the two necessary user
192          entries to have an LDAP PyKota Admin and an LDAP PyKota
193          ReadOnly user. The sample configuration files were updated
194          to contain the default passwords used in the LDIF file.
195         
196        - dumpykota is now more strict when checking arguments.   
197       
198    - 1.23 :
199   
200        - Many minor bug fixes and code cleaning.
201       
202        - Improved documentation.
203       
204        - Added Polish translation.
205       
206        - Improved French and Swedish translations.
207       
208    - 1.23beta :
209   
210        - Now the mailto directive is honored in all cases where the job is
211          denied or a warning has to be issued, and the correct reason
212          can be sent back to the user.
213         
214        - The PYKOTAREASON environment variable, if defined, contains the 
215          textual reason why the job was denied or a warning has to be
216          issued.
217       
218    - 1.23alpha31 :
219   
220        - Added support for --maxjobsize, --passthrough and --nopassthrough
221          in pkprinters. These modes are now also honored when printing.
222         
223        - Allows the admin to restrict the number of print queues which will
224          be treated by pkturnkey by passing queues' names as additionnal
225          arguments on pkturnkey's command line.
226         
227        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
228          command line option.   
229         
230    - 1.23alpha30 :
231   
232        - Database changes : you MUST use upgrade-to-1.23.sql again if you
233          use PostgreSQL, or copy the new schema and restart your LDAP
234          server if you use LDAP.
235         
236        - The -C | --comment command line switch was added to edpykota to 
237          attach textual information to modifications done to a user's
238          account balance.
239         
240        - The -l | --limitby command line switch to edpykota was modified 
241          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
242          command's help or manual page for details.
243         
244        - The -i | --ingroups command line switch to repykota allows 
245          PyKota Administrators to only lists members of the specified
246          group or groups (separated with commas).
247         
248        - The -I | --increase command line switch to edpykota allows
249          to increase or decrease page limits.
250         
251        - Added the precomputed job's size and price to the history
252          for controlling purpose.
253       
254    - 1.23alpha29 :
255   
256        - Fixed a small problem with billing codes.
257       
258        - Exports some environment variables earlier, to render the script
259          launched by the overwrite_jobticket directive more powerful.
260         
261        - Now autopykota also creates print quota entries for the user on the
262          printers groups the current printer is a member of.
263         
264    - 1.23alpha28 :
265   
266        - Added users groups management to pkturnkey.
267       
268        - Fixed umask in setup script.
269       
270    - 1.23alpha27 :
271   
272        - Replaced the --dryrun command line option by the --force
273          command line option in pkturnkey, with exactly the opposite
274          effect (for security reasons).
275         
276    - 1.23alpha26 :
277   
278        - Allows parametrized pjl and snmp hardware accounting methods,
279          to be able to respectively set the TCP port and the SNMP

285       
286        - Improved pkturnkey's general usability.
287       
288        - Added a manpage for pkturnkey.
289       
290    - 1.23alpha24 :
291   
292        - Allows different databases to be used depending on the
293          user's rights. This allows PyKota admins to directly
294          use a master LDAP server for read+write, while letting
295          normal users using the replicas for readonly access.
296          NB : using different storage backends is also possible,
297          but you're on your own there.
298         
299    - 1.23alpha23 :
300   
301        - Fixed a problem with banner accounting.
302   
303        - Introduction of the new 'pkturnkey' command line tool.
304       
305    - 1.23alpha22 :
306   
307        - The cupspykota backend was almost entirely rewritten from scratch.
308          It's now much more readable, maintainable, etc...
309         
310        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
311          advised to download earlier releases or purchase the
312          PyKota v1.22HotFix1 Official release. LPRng support
313          MIGHT be re-added later.
314       
315    - 1.23alpha21 :
316     
317        - Fix for IPP requests which contain more than a single
318          job-originating-host-name attribute.
319         
320    - 1.23alpha20 :
321   
322        - Added the overwrite_jobticket directive. See pykota.conf.sample
323          for how to use it.
324         
325    - 1.23alpha19 :
326   
327        - Fixed an LDAP filtering problem when managing billing codes.
328       
329        - Added the unknown_billingcode directive. See pykota.conf.sample
330          for how to use it.
331       
332    - 1.23alpha18 :
333     
334        - Added the dump_bfd.php contribution.
335       
336        - Several fixes in the internal PJL accounter.
337       
338        - Now autopykota doesn't create unneeded print quota entries anymore.
339       
340        - Increased the timeout in the PJL hardware accounting code to
341          accomodate some printers (HP5000 at least).
342         
343    - 1.23alpha17 :
344   
345        - pkpgcounter is now distributed separately only. This
346          means that people must now download and install pkpgcounter
347          v1.56 or higher prior to being able to run PyKota.
348         
349        - Removed all the autoconf/automake stuff which was outdated 
350          and confusing.
351         
352    - 1.23alpha16 :
353     
354        - Extracted the GPL blurb from all commands' help, and use
355          a static version only once. This saves space big time, and
356          eases future translations.
357         
358    - 1.23alpha15 :
359   
360        - pkbcodes now works with the PostgreSQL backend.
361          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
362       
363    - 1.23alpha14 :
364   
365        - Logs a warning when the user/group doesn't exist when running
366          edpykota.
367         
368    - 1.23alpha13 :
369   
370        - Minor fix for user groups because of latest database changes.
371       
372    - 1.23alpha12 :
373   
374        - Big database changes, use the migration scripts !
375       
376    - 1.23alpha11 :
377   
378        - Small fix to the PCL3/4/5 parser for some drivers.
379       
380    - 1.23alpha10 :
381   
382        - Fixed a bad exception name in cupspykota when parsing IPP messages.
383       
384        - Improved the IPP messages module : it can now generate IPP messages
385          in addition to parsing them.
386       
387    - 1.23alpha9 :   
388   
389        - The denyduplicates directive now accepts a command line as an
390          argument beside yes/no. The command is launched and must
391          print either ALLOW or DENY to its standard output. Then the
392          job gets allowed or denied by PyKota.
393          This will allow user interaction in the near future.
394         
395        - Introduced the new 'striptitle' directive to remove ugly prefixes
396          from print job's titles whenever a new print job is submitted.
397         
398        - Fixed internal SNMP accounter for printers which only have a life time
399          page counter, and not a volatile page counter.
400         
401    - 1.23alpha8 :
402   
403        - The data dumper can now summarize payments and history with the
404          help of the --sum command line option (or checkbox in the CGI).
405         
406        - The message used when the job's filename, title and options are
407          hidden because of the privacy directive is now translated at
408          retrieval time, instead of at saving time.
409         
410        - Minor fix in the LDAP backend code. 
411         
412    - 1.23alpha7 :
413   
414        - Improvements to the internal PJL and SNMP accounter : now should
415          support more printers and waste less time.
416         
417    - 1.23alpha6 :
418   
419        - The data dumper's start= and end= date filtering options now
420          accept a positive or negative offset to be added to the special
421          keywords 'yesterday', 'today', 'now', 'tomorrow'.
422          e.g. : dumpykota --data history start=yesterday-5 end=today
423         
424    - 1.23alpha5 :
425   
426        - The data dumper's start= and end= date filtering options now accept
427          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
428         
429    - 1.23alpha4 :
430   
431        - The data dumper now accept start= and end= to specify the starting
432          and ending dates to dump the history.
433         
434    - 1.23alpha3 :
435   
436        - The destination link for the logo used in CGI scripts is
437          configurable.
438         
439        - Data dumper improved : it's faster and now datas are correctly
440          escaped.
441       
442        - The URL to the logo displayed in the CGI scripts is configurable.
443       
444    - 1.23alpha2 :
445   
446        - Fixed edpykota --prototype with balance.
447       
448        - Major rewrite of the IPP message parsing code to definitely
449          fix the job-originating-hostname IPP attribute problem.
450       
451    - 1.23alpha1 :   
452   
453        - Sets current username to the user CUPS runs as instead of "root"
454          when printing test pages from CUPS' web interface (because
455          the username is empty in this case).
456         
457        - Fix for strange values in job-originating-hostname
458       
459    - 1.22 :
460   
461        - Big improvements to the documentation.
462

466       
467        - Fixed a permission problem in pykotme and pykosd.
468       
469        - Fixed an inconsitency between SQL and LDAP backends'
470          behavior in edpykota.

479       
480        - Clicking on the billing code in printquota.cgi's job history
481          now shows all jobs matching this billing code.
482         
483        - Fixed the dump in CUPS' page_log format which didn't
484          dump the oldest entry.
485

490          and exported to subprocesses as the PYKOTAJOBBILLING environment
491          variable.
492         
493        - Ctrl+C now makes PyKota commands exit without a traceback.
494

513        - Allows pkbanner to accept more info to display on its
514          command line.
515         
516    - 1.22alpha3 :
517   
518        - Fixes some case related problems with some LDAP backends.
519       
520        - Fixes some problem for printers which directly go from
521          "idle" to "warmup" and never to "printing" before
522          returning to "idle".
523         
524        - Some permissions settings may have prevented cupspykota
525          from parsing cupsd.conf, this is now fixed.
526         
527    - 1.22alpha2 :
528   
529        - Introduction of the web enabled print quote generator.
530       
531        - Fixed a potential race condition when several backend
532          wrappers were present in CUPS' backend directory.
533         
534        - Fixed dumpykota's output in CUPS' page_log format to better
535          match CUPS format.
536         
537    - 1.22alpha1 :
538

562    - 1.21alpha27 :
563   
564        - Allows software() (no arguments) to the software accounting
565          directive. This saves a lot of CPU since the job is not
566          parsed again : the precomputed size is used directly in this
567          case.
568         
569        - epykota's --prototype option now works fine with accounts
570          limited by balance.

583          'enforcement' is not set to 'strict'.
584         
585        - Introduction of the new 'trustjobsize' configuration directive
586          to workaround some problematic printers. See the sample
587          configuration file for details.
588         
589    - 1.21alpha24 :
590   
591        - Big database structure changes. An upgrade script
592          is now included for PostgreSQL. LDAP users may just
593          want to copy the new schema in place.
594         
595        - edpykota now recognizes the -o | --overcharge command line
596          option to set an overcharging or undercharging factor
597          on each print job's cost for a particular user.
598         
599        - repykota's output format has changed an is not limited to 
600          80 characters wide anymore. People who used to parse
601          repykota's output in their own tools are strongly advised
602          to parse dumpykota's output instead.
603         
604        - Introduction of the new 'maxdenybanners' configuration directive
605          to allow up to N (the directive's value) deny banners to be
606          printed even if the print account is forbidden to print.
607         
608        - Better detection of the number of copies in the PostScript parser.
609       
610    - 1.21alpha23 :
611   
612        - Traditional Chinese translation added.
613   
614        - Several fixes and performance improvements with the LDAP backend.
615       
616    - 1.21alpha22 :
617   
618        - edpykota's --delete command line option doesn't consider
619          '*' to be the default argument anymore :-)
620         
621    - 1.21alpha21 :
622   
623        - dumpykota.cgi can now be run as a normal user as opposed to
624          a PyKota administrator. No read access to pykotadmin.conf is
625          necessary anymore. This CGI scripts now honors the REMOTE_USER
626          environment variable just like printquota.cgi does, see
627          the file cgi-bin/README for details.
628          The command line tool dumpykota must still be run by a PyKota
629          administrator.
630         
631        - Fix exception's name error due to a change in recent versions
632          of PygreSQL.

635         
636        - Big bug fix wrt the datelimit field which was never reset.
637         
638    - 1.21alpha19 :
639   
640        - Introduction of the new dumpykota.cgi CGI script, which
641          allows third party tools like phpPrintAnalyzer to be
642          interfaced in real time with PyKota. To use it you
643          may have to change your web server's configuration,
644          please see pykota/cgi-bin/README
645         
646    - 1.21alpha18 :
647   
648        - Now dumpykota can dump the job history into CUPS' page_log
649          format (even when the printing system is LPRng). This allows
650          people to use tools like PrintAnalyzer or phpPrintAnalyzer
651          (two completely different beasts) with PyKota.
652         
653    - 1.21alpha17 :
654     
655        - Fixed field type's name in XML dumps.
656       
657        - Now drops priviledges to user 'pykota' when launched as root
658          (directly or as a CUPS backend), if such an user exists.

670          in dumpykota's output.
671         
672        - dumpykota filtering capabilities are now supported within
673          the LDAP backend too.
674         
675    - 1.21alpha14 :
676   
677        - dumpykota now supports extended filtering possibilities
678          with the PostgreSQL backend (LDAP support will come soon).
679         
680    - 1.21alpha13 :
681   
682        - Added a --debug command line option to pkpgcounter, so
683          that people may see what really happens, and what will
684          be available in the future :-)
685         
686    - 1.21alpha12 :
687   
688        - Fixed a bug with non standard pkbanner command lines.
689

694   
695        - Now user and group print quota entries can be stored directly
696          below the user or group with the LDAP backend, using them
697          as branches. Thanks to Stefan Wold for the patch.
698          See the sample configuration file for details.
699         
700        - TLS is now supported with the LDAP backend. Thanks to Stefan
701          Wold for the patch.
702          See the sample configuration file for details.
703         
704        - edpkota now accepts the -U | --used value command line argument
705          to preset the page counters to an initial value. Thanks to
706          Wilson Roberto Afonso and Matt Hyclak for the patch.
707         
708    - 1.21alpha10 :
709   
710        - Now automatically reconnects up to three times if the LDAP server
711          returned an error, possibly due to a timeout.
712         
713    - 1.21alpha9 :
714   
715        - Now searches the configuration files in 'pykota' system user's
716          home directory. The 'pykota' system user and group have
717          to be created by the system administrator, and given
718          sufficient permissions to PyKota's configuration files.
719

762         
763    - 1.21alpha1 :
764   
765        - added an IPP messages miniparser. Extraction of the client
766          hostname is now considered to be fiable, at least until
767          the CUPS developpers change something...
768       
769    - 1.20 :
770   
771        - Version number changed.
772

785        - Minor changes in the debian directory.
786       
787    - 1.20alpha27 :
788   
789        - Fixed many problems with translation files. In particular
790          the Brazilian Portuguese translation file was incorrectly
791          installed into the french "breton" locale directory.
792         
793        - Finished French translation. 
794         
795    - 1.20alpha26 :
796

805   
806        - pkprinters allows --list to normal users, but require user
807          to be a PyKota administrator when another command line
808          option is used.
809         
810        - pkhint doesn't use absolute path to search for helper commands

818       
819        - Now warnpykota only warns users who have ever printed,
820          to not cause confusion to users who have just opened
821          their account.
822       
823        - Prepared help messages for translations.
824       
825    - 1.20alpha23 :
826   
827        - Add workaround for locale problem.
828       
829    - 1.20alpha22 :
830   
831        - Hopefully final fix for data encoding charset.
832       
833        - edpykota now refuse to work if the user is not a PyKota admin.

840          a PyKota administrator (a PyKota administrator is an user
841          allowed to read the pykotadmin.conf file).
842         
843        - Now any PyKota administrator can use repykota and warnpykota
844          with additionnal arguments, not only the root user.
845         
846        - Improved documentation a bit.
847

861        - The md5 sum of the job's datas is now available as an
862          hexadecimal digest in the PYKOTAMD5SUM environment variable.
863         
864        - The description, filename, title, and options fields
865          are now stored as UTF-8 strings in both LDAP and PostgreSQL.

889          'pjl' value in the hardware accounter.
890         
891    - 1.20alpha15 :
892   
893        - LDAP pykotaAccountBalance objects were always created
894          attached to the pykotaUser objects. This is now
895          fixed and the value of balancebase in pykota.conf
896          is now correctly used.
897         
898    - 1.20alpha14 :
899

908    - 1.20alpha13 :
909     
910        - Hardware accounter now accepts the special
911          'snmp' value, meaning ALL is done from main code
912          without launching any subprocess.
913          You need the http://pysnmp.sf.net Python module
914          for this to work (tested with v3.4.2)
915         
916        - Increased delay between two loops iterations 
917          to 2 seconds in waitprinter.sh to diminish
918          CPU load.
919         
920    - 1.20alpha12 :
921   
922        - waitprinter.sh rewritten from scratch to wait
923          for printer status stabilization.

950     
951        - Improved mailandpopup.sh script.
952       
953        - Small fixes for LPRng.
954       
955        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
956          hostname or IP address. Set to 'localhost' when not
957          meaningful.
958         
959        - Fixed issue with how mod_auth_ldap Apache modules
960          fills the REMOTE_USER environment variable.
961         
962        - Fixed a bug in LDAP user deletion code.
963       
964    - 1.20alpha5 :
965     
966        - Introduces the new configuration directive 'onaccountererror'
967          to specify what must be done whenever the software or
968          hardware accounter fails. Allowed values are 'continue' and
969          'stop' (default).
970         
971        - Minor fix in software accounter for a recently introduced
972          problem.

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

1496         
1497    - 1.18alpha4 :
1498   
1499        - Applied some of the modifications suggested by
1500          Peter Hawkins, for better Debian integration.
1501          Most notably cupspykota, pykota, and the shell
1502          scripts are now installed into /usr/share/pykota
1503          instead of into /usr/bin
1504          BEWARE : double check that your symbolic link
1505          to cupspykota is correct, and that your pykota.conf
1506          file use correct path for the shell scripts like
1507          waitprinter.sh and al.

1547          though.
1548       
1549        - Portuguese Portuguese translation replaces Brazilian
1550          Portuguese Translation. Brazilian portuguese
1551          translation is still available under the 'br' locale.
1552       
1553    - 1.16beta3 :

1560   
1561        - Small fix for job cancelling code while job already
1562          printing in CUPS backend.
1563         
1564        - Big fix wrt printing policies for unknown users. 
1565       
1566    - 1.16beta1 :
1567   
1568        - Manpages upgraded.
1569

1573       
1574          SUM((NbPages * PricePerPage) + PricePerJob)
1575         
1576          For current printer and all the printers groups it is
1577          a member of, if any.
1578         
1579          This may be difficult to grasp, but offers unprecedented
1580          flexibility.

1620       
1621    - 1.16alpha18 :
1622   
1623        - Initial code for printer groups support. Printer groups have
1624          to be added with external tools like psql or gq for example.
1625          Printer groups seems to work fine with users. Untested with user
1626          groups for now.
1627
1628        - Several minor visual problems fixed in reports.
1629       
1630        - Fixed a bug in LDAP date handling.

1636          for details.
1637       
1638        - Several environment variables are now exported when executing
1639          external commands (accounters, requesters, mailers) :
1640           
1641            PYKOTAUSERNAME => user who is printing
1642            PYKOTAPRINTERNAME => printer on which the job is being sent
1643            PYKOTATITLE => Job's title
1644            PYKOTAFILENAME => Job's filename
1645            PYKOTACOPIES => number of copies asked
1646            PYKOTAOPTIONS => print command options (-o with CUPS)
1647         
1648    - 1.16alpha17 :
1649   
1650        - Added portugues translation.
1651       
1652        - Major code refactoring in accounters.
1653

1655   
1656        - Code refactoring, and addition of a real HTML reporter, to
1657          have nice looking and useful web based reports (in the future).
1658       
1659        - Added utolower configuration option to convert all usernames
1660          to lowercase during printing.

1667    - 1.16alpha14 :
1668   
1669        - Now printing on a printer not defined in the Quota Storage,
1670          results in the job being cancelled or stopped, depending
1671          on the printing system.
1672         
1673    - 1.16alpha13 :
1674   
1675        - Small bugfix wrt Python v2.1
1676       
1677        - If username is an empty string, user root is assumed.
1678       
1679        - 'postgresql' is not recognized anymore as a storage backend,
1680          you have to use 'pgstorage' instead. 'postgresql' used to
1681          be supported for compatibility with very old PyKota versions,
1682          this is not the case anymore.
1683         
1684    - 1.16alpha12 :
1685   
1686        - Job price added to job history, to keep accounting correct
1687          if a printer price per page or per job is modified and the
1688          history is not reset : the history would have given a false
1689          amount of money charged before the printer's prices were
1690          modified, this addition solves the problem.
1691         
1692    - 1.16alpha11 :
1693   
1694        - Some preliminary modifications to the database structure for
1695          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1696          database is now provided. LDAP attributes now support
1697          eq, pres and sub indexes.
1698         
1699        - Job history now contains additional informations : 
1700          number of copies, filename, title and print options.
1701         
1702    - 1.16alpha10 :
1703       
1704        - Some modifications done to external policy handling.
1705          See sample configuration file for details.
1706   
1707        - Spanish translation added.
1708       
1709    - 1.16alpha9 :
1710   
1711        - mailto can be set to external(...) to warn users above
1712          quota with any command of your choice (e.g. linpopup).
1713          Several parameters are available, see sample configuration
1714          file for details.
1715         
1716    - 1.16alpha8 :
1717   
1718        - Now cupspykota transmits SIGTERMS to the original 
1719          backend when the user deletes a job being processed.
1720         
1721        - The documentation is now licensed under the terms of the
1722          GNU GPL too.
1723         
1724    - 1.16alpha7 :
1725   
1726        - The CUPS backend is now fully functionnal (it seems).
1727       
1728        - From now on, the use of the pykota filter with CUPS
1729          is deprecated. The pykota filter still has to be
1730          used with LPRng though.
1731       
1732    - 1.16alpha6 :
1733   
1734        - Bug fixed : when edpykota was used to add a printer
1735          with no user or group name, a bad user/group name "*" was
1736          added to the database.
1737         
1738    - 1.16alpha5 :
1739   
1740        - New CUPS backend supports device enumeration !
1741          This means that NO manual CUPS configuration has to
1742          be done. All can now be done from CUPS web interface.
1743       
1744    - 1.16alpha4 :
1745   
1746        - New CUPS backend added.
1747       
1748    - 1.16alpha3 :

1768        - Command line tools now accept multiple printer
1769          names or wildcards, separated with commas.
1770         
1771    - 1.15alpha9 :
1772   
1773        - External policy can be used to auto-add unknown users
1774          and any other interesting things you may want to do.
1775          WARNING : You can't auto-add printers for now.
1776          They have to be created manually before.
1777          Look at sample configuration file for examples.
1778         
1779    - 1.15alpha8 :
1780   
1781        - Job history can be disabled if needed.
1782          This feature may be useful for people who use the LDAP
1783          backend and don't want their LDAP tree to grow out of
1784          control.
1785       
1786    - 1.15alpha7 :
1787   
1788        - More work done on caching wrt groups.

1797
1798    - 1.15alpha4 :
1799   
1800        - Problem with Python 2.3 fixed. Needs some definitive
1801          modification.
1802         
1803    - 1.15alpha3 :
1804   
1805        - CGI script now tries to restrict view when the
1806          REMOTE_USER environment variable is set. This allows
1807          people to protect its use with .htaccess files.
1808          When unprotected, or if REMOTE_USER is 'root', then
1809          unrestricted access is granted.
1810          NB : REMOTE_USER is automatically set by the web server
1811          (e.g. Apache) when a page with restricted access is viewed.
1812         
1813    - 1.15alpha2 :
1814

1818       
1819    - 1.15alpha1 :
1820   
1821        - Bug fix in SQL code.
1822       
1823    - 1.14 :
1824   
1825        - The PostgreSQL database connection is now always closed before
1826          exit. The LDAP database connection too, but it didn't suffer
1827          from the problem anyway, AFAICT.
1828       
1829    - 1.14beta2 :
1830   
1831        - An LDAP-specific configuration field was introduced, usermail.
1832          Use it to specify which LDAP attribute contains a valid email
1833          address for the user. See sample configuration file for
1834          details.
1835       
1836    - 1.14beta :
1837   
1838        - Two new LDAP-specific configuration fields were introduced,
1839          newuser and newgroup. Use them to specify if you want to add
1840          quota information to existing entries or elsewhere.
1841          See sample configuration file for details.
1842         
1843    - 1.14alpha9 :
1844   
1845        - Documentation improved.
1846       
1847        - pykotme now also prints the user's account balance value
1848          if the user is registered in the Quota Storage and his
1849          limiting factor is "balance".
1850         
1851    - 1.14alpha8 :
1852   
1853        - bin/waitprinter.sh is now included to wait for
1854          SNMP enabled printers to be idle again before
1855          asking for their internal page counter.
1856          See sample configuration file for details.
1857         
1858    - 1.14alpha7 :
1859   
1860        - edpykota now doesn't check if the user/group is above
1861          quota. The check is only done at print time. This
1862          prevents the sending of email messages when creating
1863          user quotas if quota is already reached at creation
1864          time.
1865         
1866    - 1.14alpha6 :
1867   
1868        - Configuration file split and moved to /etc/pykota/pykota.conf
1869          and /etc/pykota/pykotadmin.conf to prevent simple users to
1870          have Read/Write access to the Quota Database.
1871          Don't forget to :
1872         
1873                $ chmod 640 /etc/pykota/pykotadmin.conf
1874               
1875        - storageuser and storageuserpw configuration fields reintroduced
1876          for the same reason.
1877         
1878        - Code cleaning for future implementation of email addresses
1879          support in the PostgreSQL and LDAP backends.
1880         
1881    - 1.14alpha5 :
1882       
1883        - Big bug fixed when changing the prices for a printer
1884       
1885    - 1.14alpha4 :
1886   
1887        - When adding an user, the user itself and its account balance
1888          are now added in the same LDAP entry. Before they were added
1889          as two different LDAP entries.
1890         
1891    - 1.14alpha3 :
1892   
1893        - Email field added to PostgreSQL database. An upgrade script

1903          balance (below 1.0 by default, configurable) are sent
1904          a warning message.
1905         
1906        - All warning messages to users are now configurable. 
1907          NB : Warning messages to the administrator are not.

1910   
1911        - Some small fixes wrt group handling.
1912       
1913        - The whole module code was passed through PyChecker and
1914          several small code inconsistencies were fixed,
1915          as well as a bug in the groups code.
1916         
1917    - 1.13alpha1 :
1918

1936          printing quotes for users.
1937         
1938    - 1.10 :
1939   
1940        - Bug fixed wrt quota reports when print limiting is by
1941          account balance.
1942         
1943    - 1.09 :

1968          and groups names may contain wildcards.
1969         
1970        - repykota and warnpykota only reports or warns the
1971          current user when launched by non-root users.
1972         
1973        - Minor bug fixes. 
1974   
1975    - 1.09alpha1 :
1976   
1977        - More work on LDAP storage backend. Many options
1978          were added to /etc/pykota.conf to give some
1979          hints to the LDAP storage backend.
1980         
1981        - Severe database access optimizations were done by
1982          rewriting most of the Quota Storage backends drivers.

1992        - Code refactoring.
1993       
1994        - A single user/password pair is used to connect
1995          to the database backend. The storageuser configuration

1997          not used anymore.
1998         
1999        - You can now set PyKota in debug mode, see sample configuration 
2000          file for details.
2001          WARNING : only Quota Storage backend queries are logged in
2002          debug mode, for now.
2003       
2004    - 1.08alpha7 :
2005   
2006        - Very latest LDAP schema.
2007       
2008        - Code enhancement wrt easy pluggability of PyKota attributes
2009          and object classes into an existing LDAP directory.
2010       
2011    - 1.08alpha6 :
2012   
2013        - Minor bug corrections
2014       
2015        - More work on LDAP : new schema
2016       
2017    - 1.08alpha5 :
2018   
2019        - More good work on LDAP storage.
2020          repykota now works reasonably well with the sample LDAP directory.
2021       
2022    - 1.08alpha4 :
2023   
2024        - LDAP schema included.
2025          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2026          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2027          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2028          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2029          MAILING LIST.
2030         
2031    - 1.08alpha3 :
2032   
2033        - External accounting methods were partly rewritten :
2034         
2035          - No more "broken pipe" should happen.
2036         
2037          - They now take care of the number of copies
2038            This may be unneeded though, if the postscript
2039            file already does this, because this would
2040            overcharge users (number of copies counted
2041            two times). NEEDS MORE TESTING.
2042           
2043          - The sample configuration file now contains 
2044            an external accounting method example which should
2045            work with all DSC compliant Postscript files.
2046           
2047        - Some small bugs were fixed.   
2048       
2049    - 1.08alpha2 :
2050   
2051        - Now works with net-snmp v5.0 and above.
2052          It already worked, but the sample configuration
2053          file didn't contain appropriate values...
2054       
2055    - 1.07 : Release of the Shame !
2056   
2057        - The external accounting methods driver was left out of
2058          the CVS tree. Nobody could use it since it wasn't included !
2059         
2060    - 1.06 :
2061   
2062        - Severe bug fixed : if you had a printer in
2063          power saving state which couldn't answer immediately,
2064          a bug was triggered.
2065          It was caused by a bad copy/paste which
2066          forgot to import a Python module at run time.
2067         
2068    - 1.05 :
2069   
2070        - External accounters are finally available !
2071          This means that you can plug any page accounting
2072          method you like by setting the appropriate
2073          'accounter' field in /etc/pykota.conf
2074          See the sample conf/pykota.conf.sample to
2075          learn how to do.
2076         
2077          NB : Both 'external' and 'stupid' accounting methods
2078               account a job size just before *this* job is
2079               sent to the printer.
2080               The original 'querying' method accounts a job
2081               size just before *the next* job is sent to
2082               the printer.
2083       
2084    - 1.05alpha3 :
2085   
2086        - A 'stupid' and unreliable accounting method was
2087          implemented to serve as an example on how to
2088          do this sort of things. This method only counts
2089          the 'showpage' statements in the input data.
2090          See sample configuration file for details.
2091          Pluggable accounting methods work, but I advise
2092          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2093          It is not reliable enough to be used.
2094          Use the 'querying' accounting method instead.
2095         
2096    - 1.05alpha2 :
2097   
2098        - Pluggable accounting methods.
2099       
2100        - Better error handling.
2101       
2102    - 1.05alpha1 :
2103   
2104        - SECURITY file added to help improve PyKota's security.
2105       
2106        - Extracting the printer's internal page counter is now
2107          tried several times, waiting several seconds between
2108          two tries. This lets the time to warm up for some printers
2109          which don't answer when they are sleeping (my Apple
2110          LaserWriter 16/600 PS is in this case, maybe others too)
2111         
2112        - Small display bug fixed in repykota
2113         
2114    - 1.04 :
2115   
2116        - Default print policy for users/groups unknown from
2117          the print quota system is now DENY instead of ALLOW,
2118          since ALLOW can generate inaccurate results
2119          (incorrect job sizes charged to the wrong persons)
2120         
2121        - LPRng support works !
2122       
2123        - A bug was introduced some time ago wrt printers' default
2124          policy for unknown users. It is now corrected.
2125       
2126        - repykota now displays prices per job and per page for each
2127          printer, if they are defined.
2128         
2129        - Minor display bug fixed in repykota.
2130       
2131        - Problem when running repykota with an empty database was fixed.
2132       
2133    - 1.03 :
2134   
2135        - Upgrade script included for earlier versions.
2136          Please look inside the initscripts subdirectory.
2137          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2138         
2139        - repykota now reports account balances too.
2140       
2141        - PyKota now has a nice logo, see the logos
2142          subdirectory.
2143       
2144        - Manual pages were finally updated.
2145       
2146        - Group quotas seem to work now !
2147       
2148        - The new database schema allows to keep an history of all
2149          jobs as well as charge users per page and/or per job,
2150          and track users' account balance.
2151         
2152        - edpykota now accepts much more command line options to 
2153          use the new functionnalities. See edpykota --help for
2154          details.
2155         
2156        - The installation script now allows to install the sample
2157          configuration file during first installation.
2158         
2159        - More group quota code works, but still not finished. 
2160       
2161        - The CGI script displays a link to PyKota's website.
2162       
2163        - The job history is now kept, this will allow per-period
2164          reports in the future.
2165         
2166        - After having modified the quota for an user with edpykota,
2167          a quota check is done to eventually warn the user/admin about
2168          a quota which is too low to print.
2169         
2170        - A workaround is provided for HP Printers : their internal
2171          page counter is only saved to NVRAM in a 10 increment, so
2172          if you switch them off and then on, the reported page counter
2173          may be lower than the real number of pages printed.
2174          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2175          We unconditionnally set the last job's page count to
2176          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2177          in this case.
2178          For a more accurate accounting, never switch your HP printers
2179          off.
2180         
2181        - A fix is provided for printers which only have a volatile 
2182          page counter (reset to 0 every time you switch the printer on)
2183          This should allow PyKota to work reasonably fine with HP Laserjet
2184          4L/5L/6L, not perfect, but better than nothing.
2185          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2186          For a more accurate accounting, never switch your HP printers
2187          off. This is untested, please report any problem.
2188         
2189        - A bug was fixed when edpykota --add was used with users who already
2190          had a quota on the specified printer.
2191         
2192        - A small display bug in repykota was introduced in preliminary
2193          1.03 versions, and fixed later on.
2194         
2195        - Some minor bugs which happened in rare situations were fixed.
2196       
2197        - Support for AppleTalk printers was added, see sample configuration
2198          file for details.
2199         
2200        - Users and group printing can now be controlled (limited) either by 
2201          print quota or by account balance.
2202       
2203    - 1.02 :
2204   
2205        - The installation script now checks for software availability
2206          and in case a software is missing asks the user if he
2207          wants to continue with the installation or abort it.
2208         
2209        - The configuration file pykota.conf is now expected to be
2210          found in /etc instead of in /etc/cups
2211          The installation script prompts the user to see if he
2212          wants to move an old configuration file to the new location
2213          if needed.
2214         
2215        - Improved documentation.
2216       
2217        - You can now set the tcp/ip port on which the Quota Storage
2218          Server is listening, see sample configuration file for details.
2219       
2220        - Better general error handling.
2221       
2222        - Upgrade script for pre 1.01 PostgreSQL database schema is now
2223          included as well.
2224       
2225    - 1.01 :
2226   
2227        - The configuration file now accepts an option   
2228          to choose the recipient(s) of the email messages :
2229         
2230            - DevNull means no one will receive them.
2231            - User means only the user will receive them.
2232            - Admin means only the admin will receive them.
2233            - Both means the User and the Admin will receive them.
2234           
2235        - The configuration file now uses hard-coded default values
2236          when an option is not set. See sample configuration file
2237          for details.
2238         
2239        - Manual pages are included since 1.00, but I forgot to   
2240          add this information to this file.
2241         
2242        - Redistribution terms for the official package have 
2243          softened and are now fully GPL compatible :
2244          unrestricted modification is now allowed even for
2245          the version number.
2246         
2247    - 1.00 :
2248   
2249        - edpykota now accepts a --noquota option. This
2250          disable quota checking while still doing page
2251          accounting. This is really useful for people
2252          who don't want to limit their users but want
2253          to know how much pages they print.
2254         
2255        - Some untested scripts were added to retrieve
2256          the life time page counter of non-SNMP printers.
2257         
2258        - Every directory now has a specific README file. 
2259       
2260    - 0.99 :
2261   
2262        - Under some circumstances while the user wasn't allowed
2263          to print, he didn't receive any email message. It is
2264          now fixed.
2265         
2266        - When an user wasn't allowed to print, the quota for
2267          the previous user wasn't updated. This is now fixed.
2268         
2269    - 0.98 :
2270   
2271        - Correctly handle the case where the printer is switched off.
2272       
2273        - Small bug wrt syslog fixed.
2274       
2275    - 0.97 :
2276   
2277        - edpykota accepts wildcards on its command line for users/groups too
2278          if the --add option is not set, e.g. :
2279         
2280              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
2281             
2282        - If no user name is passed at all, then a default wildcard of "*"
2283          which means apply the command on ALL users for this printer is used.
2284         
2285        - Small bug fixes.
2286       
2287    - 0.96 :
2288
2289        - Options requester, policy, admin, adminmail and gracedelay can now
2290          be set either globally or per printer. The printer option has
2291          priority if both are defined.
2292
2293        - More powerful configuration parser.
2294       
2295        - If all options are defined globally, there's no need to
2296          define a section for each printer in the configuration
2297          file anymore. Just define a [global] section and it's ok.
2298
2299    - 0.95 :
2300
2301        - External requesters for printers finally added.
2302
2303        - Full internationalization (english and french are supported)
2304 
2305        - More complete quota usage report
2306
2307        - CGI script to access to the quota usage report
2308
2309        - Several bugs fixed.
2310
2311
2312    - 0.9 :
2313
2314        - First public version
