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

227       
228        - Added a manpage for pkturnkey.
229       
230    - 1.23alpha24 :
231   
232        - Allows different databases to be used depending on the
233          user's rights. This allows PyKota admins to directly
234          use a master LDAP server for read+write, while letting
235          normal users using the replicas for readonly access.
236          NB : using different storage backends is also possible,
237          but you're on your own there.
238         
239    - 1.23alpha23 :
240   
241        - Fixed a problem with banner accounting.
242   
243        - Introduction of the new 'pkturnkey' command line tool.
244       
245    - 1.23alpha22 :
246   
247        - The cupspykota backend was almost entirely rewritten from scratch.
248          It's now much more readable, maintainable, etc...
249         
250        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
251          advised to download earlier releases or purchase the
252          PyKota v1.22HotFix1 Official release. LPRng support
253          MIGHT be re-added later.
254       
255    - 1.23alpha21 :
256     
257        - Fix for IPP requests which contain more than a single
258          job-originating-host-name attribute.
259         
260    - 1.23alpha20 :
261   
262        - Added the overwrite_jobticket directive. See pykota.conf.sample
263          for how to use it.
264         
265    - 1.23alpha19 :
266   
267        - Fixed an LDAP filtering problem when managing billing codes.
268       
269        - Added the unknown_billingcode directive. See pykota.conf.sample
270          for how to use it.
271       
272    - 1.23alpha18 :
273     
274        - Added the dump_bfd.php contribution.
275       
276        - Several fixes in the internal PJL accounter.
277       
278        - Now autopykota doesn't create unneeded print quota entries anymore.
279       
280        - Increased the timeout in the PJL hardware accounting code to
281          accomodate some printers (HP5000 at least).
282         
283    - 1.23alpha17 :
284   
285        - pkpgcounter is now distributed separately only. This
286          means that people must now download and install pkpgcounter
287          v1.56 or higher prior to being able to run PyKota.
288         
289        - Removed all the autoconf/automake stuff which was outdated 
290          and confusing.
291         
292    - 1.23alpha16 :
293     
294        - Extracted the GPL blurb from all commands' help, and use
295          a static version only once. This saves space big time, and
296          eases future translations.
297         
298    - 1.23alpha15 :
299   
300        - pkbcodes now works with the PostgreSQL backend.
301          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
302       
303    - 1.23alpha14 :
304   
305        - Logs a warning when the user/group doesn't exist when running
306          edpykota.
307         
308    - 1.23alpha13 :
309   
310        - Minor fix for user groups because of latest database changes.

317   
318        - Small fix to the PCL3/4/5 parser for some drivers.
319       
320    - 1.23alpha10 :
321   
322        - Fixed a bad exception name in cupspykota when parsing IPP messages.
323       
324        - Improved the IPP messages module : it can now generate IPP messages
325          in addition to parsing them.
326       
327    - 1.23alpha9 :   
328   
329        - The denyduplicates directive now accepts a command line as an
330          argument beside yes/no. The command is launched and must
331          print either ALLOW or DENY to its standard output. Then the
332          job gets allowed or denied by PyKota.
333          This will allow user interaction in the near future.
334         
335        - Introduced the new 'striptitle' directive to remove ugly prefixes
336          from print job's titles whenever a new print job is submitted.
337         
338        - Fixed internal SNMP accounter for printers which only have a life time
339          page counter, and not a volatile page counter.
340         
341    - 1.23alpha8 :
342   
343        - The data dumper can now summarize payments and history with the
344          help of the --sum command line option (or checkbox in the CGI).
345         
346        - The message used when the job's filename, title and options are
347          hidden because of the privacy directive is now translated at
348          retrieval time, instead of at saving time.
349         
350        - Minor fix in the LDAP backend code. 
351         
352    - 1.23alpha7 :
353   
354        - Improvements to the internal PJL and SNMP accounter : now should
355          support more printers and waste less time.
356         
357    - 1.23alpha6 :
358   
359        - The data dumper's start= and end= date filtering options now
360          accept a positive or negative offset to be added to the special

363         
364    - 1.23alpha5 :
365

376        - The destination link for the logo used in CGI scripts is
377          configurable.
378         
379        - Data dumper improved : it's faster and now datas are correctly
380          escaped.
381       
382        - The URL to the logo displayed in the CGI scripts is configurable.
383       
384    - 1.23alpha2 :
385   
386        - Fixed edpykota --prototype with balance.
387       
388        - Major rewrite of the IPP message parsing code to definitely

392   
393        - Sets current username to the user CUPS runs as instead of "root"

497       
498    - 1.21beta :
499   
500        - Prepared translation files for next release.
501       
502    - 1.21alpha27 :
503   
504        - Allows software() (no arguments) to the software accounting
505          directive. This saves a lot of CPU since the job is not
506          parsed again : the precomputed size is used directly in this
507          case.
508         
509        - epykota's --prototype option now works fine with accounts
510          limited by balance.
511         
512    - 1.21alpha26 :
513   
514        - Fixed the handling of the 'maxdenybanners' directive.
515       
516        - Introduced the 'denyduplicates' directive.
517       
518        - Fixed some database related glitches.
519       
520    - 1.21alpha25 :
521   
522        - The job's size is now always precomputed, even when
523          'enforcement' is not set to 'strict'.
524         
525        - Introduction of the new 'trustjobsize' configuration directive
526          to workaround some problematic printers. See the sample
527          configuration file for details.
528         
529    - 1.21alpha24 :
530   
531        - Big database structure changes. An upgrade script
532          is now included for PostgreSQL. LDAP users may just
533          want to copy the new schema in place.
534         
535        - edpykota now recognizes the -o | --overcharge command line
536          option to set an overcharging or undercharging factor
537          on each print job's cost for a particular user.
538         
539        - repykota's output format has changed an is not limited to 
540          80 characters wide anymore. People who used to parse
541          repykota's output in their own tools are strongly advised
542          to parse dumpykota's output instead.
543         
544        - Introduction of the new 'maxdenybanners' configuration directive
545          to allow up to N (the directive's value) deny banners to be
546          printed even if the print account is forbidden to print.
547         
548        - Better detection of the number of copies in the PostScript parser.
549       
550    - 1.21alpha23 :
551   
552        - Traditional Chinese translation added.
553   
554        - Several fixes and performance improvements with the LDAP backend.
555       
556    - 1.21alpha22 :
557   
558        - edpykota's --delete command line option doesn't consider
559          '*' to be the default argument anymore :-)
560         
561    - 1.21alpha21 :
562   
563        - dumpykota.cgi can now be run as a normal user as opposed to
564          a PyKota administrator. No read access to pykotadmin.conf is
565          necessary anymore. This CGI scripts now honors the REMOTE_USER
566          environment variable just like printquota.cgi does, see
567          the file cgi-bin/README for details.
568          The command line tool dumpykota must still be run by a PyKota
569          administrator.
570         
571        - Fix exception's name error due to a change in recent versions
572          of PygreSQL.   
573         
574    - 1.21alpha20 :
575         
576        - Big bug fix wrt the datelimit field which was never reset.
577         
578    - 1.21alpha19 :
579   
580        - Introduction of the new dumpykota.cgi CGI script, which
581          allows third party tools like phpPrintAnalyzer to be
582          interfaced in real time with PyKota. To use it you
583          may have to change your web server's configuration,
584          please see pykota/cgi-bin/README
585         
586    - 1.21alpha18 :
587   
588        - Now dumpykota can dump the job history into CUPS' page_log
589          format (even when the printing system is LPRng). This allows
590          people to use tools like PrintAnalyzer or phpPrintAnalyzer
591          (two completely different beasts) with PyKota.
592         
593    - 1.21alpha17 :
594     
595        - Fixed field type's name in XML dumps.
596       
597        - Now drops priviledges to user 'pykota' when launched as root
598          (directly or as a CUPS backend), if such an user exists.
599         
600        - Fixed PCL3/4/5 parser for some drivers' output.
601       
602    - 1.21alpha16 :
603

605          thanks to Matt Hyclak.
606         
607    - 1.21alpha15 :
608     
609        - Normalized field names between LDAP and PostgreSQL backends
610          in dumpykota's output.
611         
612        - dumpykota filtering capabilities are now supported within
613          the LDAP backend too.
614         
615    - 1.21alpha14 :
616   
617        - dumpykota now supports extended filtering possibilities
618          with the PostgreSQL backend (LDAP support will come soon).
619         
620    - 1.21alpha13 :
621   
622        - Added a --debug command line option to pkpgcounter, so
623          that people may see what really happens, and what will
624          be available in the future :-)
625         
626    - 1.21alpha12 :
627   
628        - Fixed a bug with non standard pkbanner command lines.
629

631          computed job sizes. **CUPS only for now**
632         
633    - 1.21alpha11 :
634   
635        - Now user and group print quota entries can be stored directly
636          below the user or group with the LDAP backend, using them
637          as branches. Thanks to Stefan Wold for the patch.
638          See the sample configuration file for details.
639         
640        - TLS is now supported with the LDAP backend. Thanks to Stefan
641          Wold for the patch.
642          See the sample configuration file for details.
643         
644        - edpkota now accepts the -U | --used value command line argument
645          to preset the page counters to an initial value. Thanks to
646          Wilson Roberto Afonso and Matt Hyclak for the patch.
647         
648    - 1.21alpha10 :
649   
650        - Now automatically reconnects up to three times if the LDAP server
651          returned an error, possibly due to a timeout.
652         
653    - 1.21alpha9 :
654   
655        - Now searches the configuration files in 'pykota' system user's
656          home directory. The 'pykota' system user and group have
657          to be created by the system administrator, and given
658          sufficient permissions to PyKota's configuration files.
659         
660    - 1.21alpha8 :
661   
662        - Added the new reject_unknown directive to reject the
663          creation of user or groups which are unknown to the system.

690    - 1.21alpha3 :
691   
692        - PyKota can now generate its own banners, and either account
693          for them or not, depending on newly introduced directives
694          in pykota.conf
695          Thanks to Matt Hyclak for the patch.
696         
697    - 1.21alpha2 :

702         
703    - 1.21alpha1 :
704   
705        - added an IPP messages miniparser. Extraction of the client
706          hostname is now considered to be fiable, at least until
707          the CUPS developpers change something...
708       
709    - 1.20 :
710   
711        - Version number changed.
712

717        - German translation was finalized.
718       
719        - Greek translation was finalized.
720       
721        - For urgent legal reasons, a "privacy" directive has been added
722          to pykota.conf, to hide jobs' title, filename and options
723          in the history.
724         
725        - Minor changes in the debian directory.
726       
727    - 1.20alpha27 :
728   
729        - Fixed many problems with translation files. In particular
730          the Brazilian Portuguese translation file was incorrectly
731          installed into the french "breton" locale directory.
732         
733        - Finished French translation. 
734         
735    - 1.20alpha26 :
736   
737        - LPRng support code should now better detect network
738          printers' hostnames or IP addresses.
739         
740        - Fix for recently introduced bug in LPRng support.
741       
742        - Fix for incorrect locale setting when starting.
743       
744    - 1.20alpha25 :
745   
746        - pkprinters allows --list to normal users, but require user
747          to be a PyKota administrator when another command line
748          option is used.
749         
750        - pkhint doesn't use absolute path to search for helper commands
751          anymore.
752         
753        - Spanish translation ready for 1.20.   
754       
755    - 1.20alpha24 :
756   
757        - Now warnpykota only warns users limited by balance once.
758       
759        - Now warnpykota only warns users who have ever printed,
760          to not cause confusion to users who have just opened
761          their account.
762       
763        - Prepared help messages for translations.
764       
765    - 1.20alpha23 :
766   
767        - Add workaround for locale problem.
768       
769    - 1.20alpha22 :
770   
771        - Hopefully final fix for data encoding charset.
772       
773        - edpykota now refuse to work if the user is not a PyKota admin.
774       
775        - Fixes a recently introduced bug with users groups and PostgreSQL.
776       
777    - 1.20alpha21 :
778   
779        - Now dumpykota refuses to launch if the current user is not
780          a PyKota administrator (a PyKota administrator is an user
781          allowed to read the pykotadmin.conf file).
782         
783        - Now any PyKota administrator can use repykota and warnpykota
784          with additionnal arguments, not only the root user.
785         
786        - Improved documentation a bit.
787       
788    - 1.20alpha20 :
789

798       
799        - Finished implementation of LDAP support in dumpykota.
800       
801        - The md5 sum of the job's datas is now available as an
802          hexadecimal digest in the PYKOTAMD5SUM environment variable.
803         
804        - The description, filename, title, and options fields
805          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
806          Proper charset is used during extraction from the database.
807         
808    - 1.20alpha18 :
809   
810        - Experimental autopykota command to initialize user
811          account and quota entries on first print while not
812          resetting the balance value if not needed.
813         
814        - Added the new "winbind_separator" directive to strip
815          out the Samba/Winbind domain name while printing if
816          needed (Off by default).
817         
818    - 1.20alpha17 :
819   
820        - Added --hardreset command line option to edpykota.
821

825    - 1.20alpha16 :
826   
827        - Internal handling of socket based PJL queries over
828          port tcp/9100 is now available with the magic
829          'pjl' value in the hardware accounter.
830         
831    - 1.20alpha15 :
832   
833        - LDAP pykotaAccountBalance objects were always created
834          attached to the pykotaUser objects. This is now
835          fixed and the value of balancebase in pykota.conf
836          is now correctly used.
837         
838    - 1.20alpha14 :
839   
840        - Belgian translations added (copy of the french ones).
841       
842        - External hardware accounter now loops until
843          a result can be read correctly.
844         
845        - pkhint now suggest the internal snmp handling instead
846          of the external one.
847         
848    - 1.20alpha13 :
849     
850        - Hardware accounter now accepts the special
851          'snmp' value, meaning ALL is done from main code
852          without launching any subprocess.
853          You need the http://pysnmp.sf.net Python module
854          for this to work (tested with v3.4.2)
855         
856        - Increased delay between two loops iterations 
857          to 2 seconds in waitprinter.sh to diminish
858          CPU load.
859         
860    - 1.20alpha12 :
861   
862        - waitprinter.sh rewritten from scratch to wait
863          for printer status stabilization.
864       
865    - 1.20alpha11 :
866   
867        - Generic data dumper 'dumpykota' introduced.
868          Works only with PostgreSQL backend for now.
869         
870    - 1.20alpha10 :
871   
872        - Added fix for incorrect job's size computation when
873          hardware accounting fails.
874         
875    - 1.20alpha9 :
876   
877        - Small fixes wrt subprocesses.
878       
879    - 1.20alpha8 :
880   
881        - Added full support of PCL3 : HP Deskjet printers are now
882          supported.
883       
884    - 1.20alpha7 :
885   
886        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
887          Needs more work, but no documentation is available.
888       
889    - 1.20alpha6 :
890     
891        - Improved mailandpopup.sh script.
892       
893        - Small fixes for LPRng.
894       
895        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
896          hostname or IP address. Set to 'localhost' when not
897          meaningful.
898         
899        - Fixed issue with how mod_auth_ldap Apache modules
900          fills the REMOTE_USER environment variable.
901         
902        - Fixed a bug in LDAP user deletion code.
903       
904    - 1.20alpha5 :
905     
906        - Introduces the new configuration directive 'onaccountererror'
907          to specify what must be done whenever the software or
908          hardware accounter fails. Allowed values are 'continue' and
909          'stop' (default).
910         
911        - Minor fix in software accounter for a recently introduced
912          problem.
913         
914    - 1.20alpha4 :
915   
916        - Added support for more ghostscript devices in ESC/P2
917          analyzer : stcolor, st800, escp, escpc are now supported.
918         
919    - 1.20alpha3 :
920       
921        - Small improvement in PostScript parser to avoid being
922          fooled by a change in number of copies :
923          The user can't ask for 200 copies of page 1 and 1 copy
924          of page 2 to fool PyKota anymore :
925          this would have been accounted for as 1 copy only, but
926          now the maximum value seen is used.
927         
928        - Relax checks for PCL5 header to accomodate some strange
929          printer drivers.
930         
931        - Now hardware accounting method works like software
932          accounting method wrt the subprocess' output.
933         
934        - Hardware and Software accounting stop the print queue 
935          when the accounting subprocess didn't work. This will
936          be configurable in the near future.
937         
938    - 1.20alpha2 :
939   
940        - Now software accounting method reads accounter's
941          answer until a line with a single integer is
942          obtained or until all of its output has been read.
943          This should fix the problem some people have
944          when strange locale related messages are sent
945          when running subprocesses (Solaris only ?).
946         
947        - First version of ESC/P2 analyzer. Seems to work
948          ok at least with 'epson', 'epsonc', 'eps9mid'
949          and 'esp9high' ghostscript devices. Needs more
950          work to correctly analyze other devices.
951       
952    - 1.20alpha1 :
953   
954        - Fixed problem with number of copies in PCLXL parser.
955       
956        - Fixed problem with number of copies in PCL5 parser,
957          when number of copies was set outside of and before first
958          page.
959       
960        - Added workaround for number of copies directly set in
961          PostScript code.
962         
963        - Added german translation.
964       
965        - Fixed problem on first print for user group quota when
966          "enforcement: strict" is used.
967       
968        - Fixed interpolation problem in french translation.
969       
970    - 1.19 :
971   
972        - Updated existing translations.   
973       
974        - Added final Thai and Greek translations.
975       
976        - Minor last minute bug fixes.
977       
978    - 1.19beta :
979   
980        - LPRng support for both software and hardware accounting seems
981          to be OK.
982         
983        - Translation files fixed because of fuzzy matching problem. 
984       
985        - Fixed path to Swedish translation: 'sv' instead of 'se'.
986       
987        - Added first draft of Thai translation.
988       
989        - Fixed some minor bugs with Pychecker.
990       
991    - 1.19alpha35 :
992   
993        - Generic PDL analyzer now supports Binary PostScript documents
994          in addition to DSC compliant ones.
995       
996    - 1.19alpha34 :
997   
998        - LPRng support : software accounting seems to work fine,
999          but hardware accounting doesn't work yet.
1000   
1001    - 1.19alpha33 :
1002   
1003        - pykosd now accepts command line arguments. Enjoy !
1004          NB : due to a bug in xosd, you need xosd version 2.2.8
1005          or higher if you don't use the default C locale.
1006         
1007    - 1.19alpha32 :
1008   
1009        - Early (not working) version of the LPRng support rewrite.
1010       
1011        - Saner default configuration file.
1012       
1013    - 1.19alpha31 :
1014   
1015        - Fixed a double Python2.1 incompatibility with newer versions,
1016          which prevented the PCL5 and the PCLXL parsers to work with
1017          this older version of Python.
1018         
1019    - 1.19alpha30 :
1020   
1021        - Introduction of preliminary version of the pykosd command
1022       
1023        - Usernames, Groupnames and Printernames can now contain
1024          ANY character, expected '/' and '@'.
1025       
1026        - Integrated most of the Debian work from Sergio
1027          Gonz�z Gonz�z
1028         
1029    - 1.19alpha29 :
1030   
1031        - PCLXL parser should now correctly handle number of
1032          copies set for each page.
1033         
1034        - Added testsuite for generic PDL analyzer.
1035       
1036        - Typo fixed in PCLXL parser.
1037       
1038        - Correctly dispatches error messages depending on the
1039          situation : tools which can be run interactively will
1040          ALWAYS output their logs to stderr, excepted for
1041          their DEBUG messages, for which the "logger:"
1042          directive as set in pykota.conf will be honored.
1043          Tools which can't be run interactively will ALWAYS
1044          honor the "logger:" directive as set in pykota.conf
1045         
1046    - 1.19alpha28 :
1047   
1048        - The description field for printers can now be set,
1049          and is displayed in reports.
1050         
1051        - Fixed a small problem in SQL backend code.
1052         
1053        - Improved pkhint
1054       
1055        - First working PCL6 (aka PCLXL) parser !
1056          Doesn't handle copies yet.
1057       
1058    - 1.19alpha27 :
1059   
1060        - Additionnal 10% speed increase in PCL5 parser for GhostScript
1061          generated files (untested yet with other PCL files).
1062         
1063        - Reintroduced the use of mmap in PCL5 parser : this speedups
1064          PCL5 parsing by almost 4 times.
1065          This 4x with the 3x below give us in fact a twelvefold increase
1066          in performance for PCL5 parsing !
1067         
1068        - The Python accelerator Psyco is now used if available
1069          in the generic PDL parser : it speedups PCL5 parsing by
1070          almost three times automagically.
1071         
1072    - 1.19alpha26 :
1073   
1074        - Fixed PCL5 parser according to the sources of rastertohp.
1075       
1076        - Fixed number of copies handling in PCL5 parser : the number
1077          of copies could vary from page to page.
1078         
1079        - Added more debug information to PCLXL parser. 
1080       
1081    - 1.19alpha25 :
1082   
1083        - Added new "description" field to printers in both
1084          PostgreSQL and LDAP. No code to handle this yet.
1085         
1086        - Reversed the fix for power save mode in printers : 
1087          no paper or tray open would have caused people to
1088          be undercharged.
1089         
1090        - Preliminary version of MySQL initialization script.
1091         
1092    - 1.19alpha24 :
1093   
1094        - Native PDF parsing code now works perfectly with
1095          Python 2.1 and above, and is way faster than before.
1096          GhostScript is not used anymore to convert PDF to PS,
1097          because PDF is parsed directly.
1098         
1099    - 1.19alpha23 :
1100   
1101        - Fixed waitprinter.sh wrt PowerSave mode and some
1102          printers. Thanks to Ryan Suarez.
1103       
1104        - Smart PDL analyzer now recognizes PDF too : two
1105          PDF parsing methods are used : a native one which
1106          is very fast but requires Python 2.3 or above, and
1107          a slower one which uses Ghostscript. PyKota detects
1108          automatically which method to use depending on your
1109          version of Python.
1110       
1111        - All tracebacks now include PyKota's version number.
1112         
1113    - 1.19alpha22 :
1114   
1115        - Ensures that the file pointer for job's data is
1116          reset to the start of the job's datas after the
1117          job's size pre-computation phase.
1118         
1119        - Improved PostScript detection code for bad drivers
1120          which don't correctly switch languages between PJL
1121          and PS.
1122       
1123        - Even better debugging code.
1124       
1125    - 1.19alpha21 :
1126   
1127        - Additionnal check.
1128       
1129    - 1.19alpha20 :
1130   
1131        - More complete logging messages wrt accounters.
1132       
1133        - Now catches early failures occuring when the configuration
1134          files are parsed.
1135       
1136    - 1.19alpha19 :
1137   
1138        - Fixed over-verbose exits when displaying help
1139          or version.
1140         
1141        - Extended some PATH in the shell scripts 
1142       
1143        - Deleting an user now also deletes his payments history.
1144       
1145        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
1146          cause problems.
1147
1148    - 1.19alpha18 :
1149   
1150        - History of payments is now stored in the database, and
1151          updated each time an user's balance is modified with
1152          edpykota --balance. This history represents each time
1153          the user was given some positive or negative credit,
1154          but doesn't reflect price paid for jobs, which appear
1155          in the jobs history instead.
1156         
1157        - Jobs history web reports now include the job's size in
1158          bytes. Also columns were reordered to render the report
1159          more easily readable.
1160         
1161    - 1.19alpha17 :
1162   
1163        - Mysterious bug (program exited unexpectedly without leaving
1164          any log message) which occured once in a while when
1165          cancelling jobs should be fixed now.
1166         
1167        - New 'crashrecipient' directive. Disabled by 
1168          default. See sample configuration file to see how
1169          to activate it. It is suggested that you activate it.
1170         
1171        - New PYKOTAJOBSIZEBYTES environment variable exported, 
1172          which contains the job's size in bytes. Empty jobs
1173          are now denied. This value is now stored in the job
1174          history (but not yet displayed from the web interface)
1175         
1176        - Preliminary work on payments storage : the PostgreSQL 
1177          and LDAP schemas should be OK now, but no code is written
1178          yet to support this functionnality.
1179         
1180    - 1.19alpha16 :
1181   
1182        - the newuser and newgroup LDAP specific directives now accept
1183          a second parameter to attach(), "fail" or "warn". If no entry
1184          is found to attach PyKota attributes to, and "fail" was used,
1185          then action is aborted and program exits in error. If "warn"
1186          is used, a new entry is created but a warning message is logged.
1187         
1188        - The job's originating hostname is now stored in the database,
1189          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
1190       
1191    - 1.19alpha15 :
1192   
1193        - The old pykota filter is now removed. This means that
1194          currently PyKota doesn't support LPRng anymore, but
1195          LPRng support will be re-added, improved, in the near future.
1196         
1197    - 1.19alpha14 :
1198   
1199        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
1200          are now exported as environment variables.
1201         
1202        - Heavy CPU usage is now completely fixed it seems, by
1203          introducing some 0.01 second sleeping when nothing to do.
1204         
1205        - Pre-computation of the job's size is now only
1206          done when enforcement is "STRICT", this saves
1207          CPU for people who don't want to use this new
1208          feature.
1209         
1210        - New 'enforcement' directive which accepts either
1211          STRICT or LAXIST. See sample configuration file
1212          for details.
1213         
1214    - 1.19alpha13 :
1215   
1216        - Get back to an old version of the polling loop which
1217          worked fine, but non-optimally. Will be optimized
1218          as time permits.
1219         
1220    - 1.19alpha12 :
1221   
1222        - Job's size is now precomputed unconditionnally using
1223          the generic PDL analyzer.
1224          NB : This value is not yet used to pre-allow/deny the
1225          job.
1226       
1227    - 1.19alpha11 :
1228   
1229        - The pykota filter is now completely deprecated and
1230          can't be used anymore. LPRng users MUST download
1231          an older version of PyKota. CUPS users MUST use
1232          cupspykota. Better support for LPRng will come
1233          in the near future.
1234         
1235    - 1.19alpha10 :
1236   
1237        - pykotme now uses generic PDL Analyzer directly instead
1238          of spawning a new process.
1239         
1240        - Improvements to generic PDL Analyzer.
1241       
1242        - 25% Speedup in PCL parser. Getting more of the Python version
1243          will probably be difficult, since the completely table driven
1244          parser I wrote is slower than the original algorithm. Then,
1245          the original algorithm is still used for now.
1246          Probable that more speed could be achieved using mmap, at the
1247          expense of severe memory consumption.
1248       
1249        - configuration simplifications : the "accounter" directive's
1250          'hardware' arguments now accepts what was in the "requester"
1251          directive as it's content. The "requester" directive is not
1252          supported anymore. See sample configuration file for details.
1253       
1254    - 1.19alpha9 :
1255       
1256        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1257       
1258        - pykotaOptions LDAP attribute now accepts non-ascii characters
1259          too.
1260         
1261        - First try at cupspykota main loop rewrite
1262       
1263    - 1.19alpha8 :
1264   
1265        - 'querying' accounting method is now called 'hardware'
1266       
1267        - 'external' accounting method is now called 'software'
1268       
1269        - 'stupid' accounting method doesn't exist anymore
1270       
1271        - 'snmp' requester doesn't exist anymore
1272       
1273        - code simplifications in external requester
1274       
1275    - 1.19alpha7 :
1276     
1277        - Database schema change (both LDAP and PostgreSQL) to
1278          allow storage of the job-originating-hostname attribute.
1279          An SQL upgrade script is present. The code is not yet
1280          capable of setting/retrieving this attribute. Support
1281          for this functionnality will be added in the future.
1282         
1283    - 1.19alpha6 :
1284   
1285        - problems connecting to SMTP servers are now catched.
1286       
1287        - pykotme now uses pkpgcounter to compute the size of the
1288          job. This modification adds PCL5 and soon PCLXL (PCL6)
1289          support. You can now get quotes for PCL in addition to
1290          PostScript.
1291         
1292        - pkpgcounter now includes first try at PCLXL parser. 
1293          It is currently disabled until it's finished.
1294         
1295    - 1.19alpha5 :
1296   
1297        - cupspykota polling loop fix for MacOSX (at least)
1298       
1299        - logging subsystem now logs PID too, to ease diagnosing
1300          problems under heavy load.
1301         
1302        - pkpgcounter enhancements.
1303       
1304        - pkprinters --skipexisting now tells pkprinters to not
1305          modify existing printers when --add is used.
1306          pkprinters logs a warning message whenever --add is
1307          used and a printer already exists.
1308         
1309        - LDAP schema now allows accented chars in pykotaFileName
1310          and pykotaTitle attributes.
1311       
1312    - 1.19alpha4 :
1313   
1314        - a bad copy&paste prevented pkpgcounter to work at all, this
1315          is now fixed.
1316         
1317        - improved PCL support in pkpgcounter, with the use of
1318          HP PCL/PJL Reference Set
1319          PCL5 Printer Language Technical Quick Reference Guide
1320       
1321        - pkpgcounter now uses mmap to speed things up : duration
1322          is halved with the sample 87 pages PCL document I use for
1323          testing.
1324         
1325    - 1.19alpha3 :
1326   
1327        - pkprinters now accepts the --list command line argument
1328          to list informations about printers.
1329         
1330    - 1.19alpha2 :
1331   
1332        - pkpgcounter is now included as a smart external
1333          accounter which can handle both PostScript and PCL.
1334         
1335    - 1.19alpha1 :
1336   
1337        - PYKOTALIMITBY environment variable is now exported too.
1338       
1339        - Inclusion of Michele Baldessari's work on autotools.
1340       
1341    - 1.18 :
1342   
1343        - Improved documentation
1344       
1345    - 1.18beta2 :
1346     
1347        - Fix for raw jobs with cupspykota
1348       
1349    - 1.18beta :
1350   
1351        - Small fix for new waitprinter.sh script
1352       
1353        - Better tracebacks on error conditions
1354       
1355        - Improved translations
1356       
1357        - Improved documentation
1358       
1359    - 1.18alpha15 :
1360
1361        - waitprinter.sh replaced by a new and possibly faster
1362          and more powerful one.
1363   
1364        - Names can now begin with a digit.
1365       
1366        - Stability improvement for quotas set on printers groups.
1367       
1368    - 1.18alpha14 :
1369   
1370        - Catches more (all ?) problems with SMTP servers instead
1371          of breaking.
1372         
1373        - Italian translation added.
1374       
1375    - 1.18alpha13 :
1376   
1377        - Pre and Post hooks are now available in the pykota
1378          filter as well.
1379         
1380        - The pykota filter doesn't check last user's quota
1381          anymore when delayed hardware accounting is used :
1382          this will be done anyway the next time the last
1383          user will print again. This saves some database
1384          queries which are unneeded.
1385       
1386    - 1.18alpha12 :
1387   
1388        - Pre and Post hooks to external commands with many
1389          many environment variables available are useable
1390          from the cupspykota backend.
1391          See sample configuration file for details and help.
1392         
1393    - 1.18alpha11 :
1394   
1395        - Hopefully final fix wrt groups (users and printers)
1396       
1397    - 1.18alpha10 :
1398   
1399        - Fixed nested printer groups accounting.
1400       
1401        - Fixed user groups + printer groups problem.
1402       
1403    - 1.18alpha9 :
1404   
1405        - Fix for LDAP problem when job price was 0.
1406       
1407        - Fix for empty user groups with LDAP.
1408       
1409        - Preliminary version of the snmpprinterstatus command added.
1410       
1411    - 1.18alpha8 :
1412   
1413        - Don't retrieve data when not needed.
1414          This avoids many database queries.
1415       
1416    - 1.18alpha7 :
1417   
1418        - New experimental ldapcache directive to improve
1419          LDAP caching.
1420         
1421    - 1.18alpha6 :
1422       
1423        - New configuration directive added : maildomain
1424          to specify the domain to send mail to when user
1425          email address is not set in PyKota database.
1426         
1427        - More complete email message headers. 
1428         
1429    - 1.18alpha5 :
1430   
1431        - Debian packaging specific files, contributed by
1432          Peter Hawkins are now included in the project's tree.
1433         
1434        - Preliminary work on future low-level LDAP caching to speed
1435          up modifications (at least).
1436         
1437    - 1.18alpha4 :
1438   
1439        - Applied some of the modifications suggested by
1440          Peter Hawkins, for better Debian integration.
1441          Most notably cupspykota, pykota, and the shell
1442          scripts are now installed into /usr/share/pykota
1443          instead of into /usr/bin
1444          BEWARE : double check that your symbolic link
1445          to cupspykota is correct, and that your pykota.conf
1446          file use correct path for the shell scripts like
1447          waitprinter.sh and al.
1448         
1449        - pkhint command added, to help in configuring correct
1450          accounting method for PyKota.
1451         
1452    - 1.18alpha3 :
1453   
1454        - Fixed a rare bug in cupspykota backend which gave
1455          incorrect "CUPS backend died abnormally" messages.
1456       
1457    - 1.18alpha2 :
1458   
1459        - Added the pkprinters command line tool to manage printers
1460          exclusively.
1461       
1462    - 1.18alpha1 :
1463

1515         
1516          For current printer and all the printers groups it is
1517          a member of, if any.
1518         
1519          This may be difficult to grasp, but offers unprecedented

1563        - Initial code for printer groups support. Printer groups have
1564          to be added with external tools like psql or gq for example.
1565          Printer groups seems to work fine with users. Untested with user
1566          groups for now.
1567
1568        - Several minor visual problems fixed in reports.
1569       
1570        - Fixed a bug in LDAP date handling.

1580           
1581            PYKOTAUSERNAME => user who is printing
1582            PYKOTAPRINTERNAME => printer on which the job is being sent
1583            PYKOTATITLE => Job's title
1584            PYKOTAFILENAME => Job's filename
1585            PYKOTACOPIES => number of copies asked
1586            PYKOTAOPTIONS => print command options (-o with CUPS)
1587         
1588    - 1.16alpha17 :
1589   
1590        - Added portugues translation.

1613    - 1.16alpha13 :
1614   
1615        - Small bugfix wrt Python v2.1
1616       
1617        - If username is an empty string, user root is assumed.
1618       
1619        - 'postgresql' is not recognized anymore as a storage backend,
1620          you have to use 'pgstorage' instead. 'postgresql' used to
1621          be supported for compatibility with very old PyKota versions,
1622          this is not the case anymore.
1623         
1624    - 1.16alpha12 :
1625   
1626        - Job price added to job history, to keep accounting correct
1627          if a printer price per page or per job is modified and the
1628          history is not reset : the history would have given a false
1629          amount of money charged before the printer's prices were
1630          modified, this addition solves the problem.
1631         
1632    - 1.16alpha11 :
1633   
1634        - Some preliminary modifications to the database structure for
1635          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1636          database is now provided. LDAP attributes now support
1637          eq, pres and sub indexes.
1638         
1639        - Job history now contains additional informations : 
1640          number of copies, filename, title and print options.
1641         
1642    - 1.16alpha10 :
1643       
1644        - Some modifications done to external policy handling.
1645          See sample configuration file for details.
1646   
1647        - Spanish translation added.
1648       
1649    - 1.16alpha9 :
1650   
1651        - mailto can be set to external(...) to warn users above
1652          quota with any command of your choice (e.g. linpopup).
1653          Several parameters are available, see sample configuration
1654          file for details.
1655         
1656    - 1.16alpha8 :
1657   
1658        - Now cupspykota transmits SIGTERMS to the original 
1659          backend when the user deletes a job being processed.
1660

1666        - The CUPS backend is now fully functionnal (it seems).
1667       
1668        - From now on, the use of the pykota filter with CUPS
1669          is deprecated. The pykota filter still has to be
1670          used with LPRng though.
1671       
1672    - 1.16alpha6 :
1673   
1674        - Bug fixed : when edpykota was used to add a printer
1675          with no user or group name, a bad user/group name "*" was
1676          added to the database.
1677         
1678    - 1.16alpha5 :
1679   
1680        - New CUPS backend supports device enumeration !
1681          This means that NO manual CUPS configuration has to
1682          be done. All can now be done from CUPS web interface.
1683       
1684    - 1.16alpha4 :
1685   
1686        - New CUPS backend added.

1709          names or wildcards, separated with commas.
1710         
1711    - 1.15alpha9 :
1712   
1713        - External policy can be used to auto-add unknown users
1714          and any other interesting things you may want to do.
1715          WARNING : You can't auto-add printers for now.
1716          They have to be created manually before.
1717          Look at sample configuration file for examples.
1718         
1719    - 1.15alpha8 :
1720   
1721        - Job history can be disabled if needed.
1722          This feature may be useful for people who use the LDAP
1723          backend and don't want their LDAP tree to grow out of
1724          control.
1725       
1726    - 1.15alpha7 :
1727   
1728        - More work done on caching wrt groups.

1738    - 1.15alpha4 :
1739   
1740        - Problem with Python 2.3 fixed. Needs some definitive
1741          modification.
1742         
1743    - 1.15alpha3 :
1744   
1745        - CGI script now tries to restrict view when the
1746          REMOTE_USER environment variable is set. This allows
1747          people to protect its use with .htaccess files.
1748          When unprotected, or if REMOTE_USER is 'root', then
1749          unrestricted access is granted.
1750          NB : REMOTE_USER is automatically set by the web server
1751          (e.g. Apache) when a page with restricted access is viewed.
1752         
1753    - 1.15alpha2 :

1758       
1759    - 1.15alpha1 :
1760   
1761        - Bug fix in SQL code.
1762       
1763    - 1.14 :
1764   
1765        - The PostgreSQL database connection is now always closed before
1766          exit. The LDAP database connection too, but it didn't suffer
1767          from the problem anyway, AFAICT.
1768       
1769    - 1.14beta2 :
1770   
1771        - An LDAP-specific configuration field was introduced, usermail.
1772          Use it to specify which LDAP attribute contains a valid email
1773          address for the user. See sample configuration file for
1774          details.
1775       
1776    - 1.14beta :
1777   
1778        - Two new LDAP-specific configuration fields were introduced,
1779          newuser and newgroup. Use them to specify if you want to add
1780          quota information to existing entries or elsewhere.
1781          See sample configuration file for details.
1782         
1783    - 1.14alpha9 :

1786       
1787        - pykotme now also prints the user's account balance value
1788          if the user is registered in the Quota Storage and his
1789          limiting factor is "balance".
1790         
1791    - 1.14alpha8 :
1792   
1793        - bin/waitprinter.sh is now included to wait for
1794          SNMP enabled printers to be idle again before
1795          asking for their internal page counter.
1796          See sample configuration file for details.
1797         
1798    - 1.14alpha7 :
1799   
1800        - edpykota now doesn't check if the user/group is above
1801          quota. The check is only done at print time. This
1802          prevents the sending of email messages when creating
1803          user quotas if quota is already reached at creation
1804          time.
1805         
1806    - 1.14alpha6 :
1807   
1808        - Configuration file split and moved to /etc/pykota/pykota.conf
1809          and /etc/pykota/pykotadmin.conf to prevent simple users to
1810          have Read/Write access to the Quota Database.
1811          Don't forget to :
1812         
1813                $ chmod 640 /etc/pykota/pykotadmin.conf
1814               
1815        - storageuser and storageuserpw configuration fields reintroduced
1816          for the same reason.
1817         
1818        - Code cleaning for future implementation of email addresses
1819          support in the PostgreSQL and LDAP backends.
1820         
1821    - 1.14alpha5 :
1822       
1823        - Big bug fixed when changing the prices for a printer
1824       
1825    - 1.14alpha4 :
1826   
1827        - When adding an user, the user itself and its account balance
1828          are now added in the same LDAP entry. Before they were added
1829          as two different LDAP entries.
1830         
1831    - 1.14alpha3 :
1832   
1833        - Email field added to PostgreSQL database. An upgrade script

1843          balance (below 1.0 by default, configurable) are sent
1844          a warning message.
1845         
1846        - All warning messages to users are now configurable. 
1847          NB : Warning messages to the administrator are not.

1921        - Severe database access optimizations were done by
1922          rewriting most of the Quota Storage backends drivers.

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