22PyKota NEWS :
23       
24    - 1.24alpha11 :
25   
26        - The pkinvoice invoice generator command line utility is now
27          included.
28         
29    - 1.24alpha10 :   
30   
31        - Huge speed improvements when deleting users, printers, and
32          billing codes.
33         
34    - 1.24alpha9 :
35   
36        - Preliminary support for MySQL, thanks to Matt Hyclak.
37       
38    - 1.24alpha8 :
39   
40        - The 'preaccounter' configuration directive was introduced to control
41          which parser to use for precomputation of the job's size. When unset,
42          the internal parser is used just like it was previously. See
43          conf/pykota.conf.sample for more details.
44         
45        - Now subprocesses launched through the overwrite_jobticket directive
46          can also output 'CANCEL', to represent the user's own choice to
47          cancel the print job.
48         
49    - 1.24alpha7 :
50     
51        - pkbanner now handles new print limiting modes correctly.
52       
53        - The cupspykota backend wrapper now accepts to be interrupted
54          with a kill -INT. This causes an immediate and clean abort
55          of the current print job.
56         
57        - Matt Hyclak contributed the possibility to store the printing
58          history in a MySQL database. See the contributed/ directory
59          for details.
60         
61        - Added 2006 to the copyright's years.
62       
63    - 1.24alpha6 :
64   
65        - Fixed internal SNMP and PJL handling code for very fast
66          printers : PyKota didn't see them going from 'idle'
67          to 'printing' to 'idle' again.
68         
69        - Now waitprinter.sh accepts SNMP version number and
70          community name as arguments, thanks to Brandon
71          Holbrook.
72         
73        - Now command line errors and Ctrl+C repectively cause
74          PyKota commands to exit with status -2 and -3.
75         
76    - 1.24alpha5 :
77   
78        - All command line tools now accept -A | --arguments filename.args
79          as a way to bypass the shell's maximal command line size :
80          just put each argument on a line by itself in a file, and
81          pass the file's name as the -A | --arguments command line
82          option's argument. For now this won't be documented in
83          commands' helps.
84         
85        - dumpykota can now dump the complete database in XML
86          format.
87         
88    - 1.24alpha4 :
89   
90        - Added support for the SQLite3 backend.
91          See pykota/initscripts/sqlite/README.sqlite
92       
93    - 1.24alpha3 :
94   
95        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
96          so we regain priviledges before running an external
97          mailto directive.
98       
99    - 1.24alpha2 :
100   
101        - Introduce the "onbackenderror" directive in pykota.conf, to
102          control if the user must be charged or not whenever a real
103          CUPS backend fails. The default value is 'nocharge'.
104          Set it to 'charge' if you think your users can cause a CUPS
105          backend to fail.
106         
107        - Now mark original backends related problems as such in the
108          printing history. Modified printquota.cgi and pykota.css
109          to make them be more visible.
110         
111    - 1.24alpha1 :
112   
113        - Fixed a problem which caused backend errors to be ignored.
114       
115        - The sample LDIF file now contains the two necessary user
116          entries to have an LDAP PyKota Admin and an LDAP PyKota
117          ReadOnly user. The sample configuration files were updated
118          to contain the default passwords used in the LDIF file.
119         
120        - dumpykota is now more strict when checking arguments.   
121       
122    - 1.23 :
123   
124        - Many minor bug fixes and code cleaning.
125       
126        - Improved documentation.
127       
128        - Added Polish translation.
129       
130        - Improved French and Swedish translations.
131       
132    - 1.23beta :
133   
134        - Now the mailto directive is honored in all cases where the job is
135          denied or a warning has to be issued, and the correct reason
136          can be sent back to the user.
137         
138        - The PYKOTAREASON environment variable, if defined, contains the 
139          textual reason why the job was denied or a warning has to be
140          issued.
141       
142    - 1.23alpha31 :
143   
144        - Added support for --maxjobsize, --passthrough and --nopassthrough
145          in pkprinters. These modes are now also honored when printing.
146         
147        - Allows the admin to restrict the number of print queues which will
148          be treated by pkturnkey by passing queues' names as additionnal
149          arguments on pkturnkey's command line.
150         
151        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
152          command line option.   
153         
154    - 1.23alpha30 :
155   
156        - Database changes : you MUST use upgrade-to-1.23.sql again if you
157          use PostgreSQL, or copy the new schema and restart your LDAP
158          server if you use LDAP.
159         
160        - The -C | --comment command line switch was added to edpykota to 
161          attach textual information to modifications done to a user's
162          account balance.
163         
164        - The -l | --limitby command line switch to edpykota was modified 
165          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
166          command's help or manual page for details.
167         
168        - The -i | --ingroups command line switch to repykota allows 
169          PyKota Administrators to only lists members of the specified
170          group or groups (separated with commas).
171         
172        - The -I | --increase command line switch to edpykota allows
173          to increase or decrease page limits.
174         
175        - Added the precomputed job's size and price to the history
176          for controlling purpose.
177       
178    - 1.23alpha29 :
179   
180        - Fixed a small problem with billing codes.
181       
182        - Exports some environment variables earlier, to render the script
183          launched by the overwrite_jobticket directive more powerful.
184         
185        - Now autopykota also creates print quota entries for the user on the
186          printers groups the current printer is a member of.
187         
188    - 1.23alpha28 :
189   
190        - Added users groups management to pkturnkey.
191       
192        - Fixed umask in setup script.
193       
194    - 1.23alpha27 :
195   
196        - Replaced the --dryrun command line option by the --force
197          command line option in pkturnkey, with exactly the opposite
198          effect (for security reasons).
199         
200    - 1.23alpha26 :
201   
202        - Allows parametrized pjl and snmp hardware accounting methods,
203          to be able to respectively set the TCP port and the SNMP
204          community.
205         
206    - 1.23alpha25 :
207   
208        - Added a --dryrun command line switch to pkturnkey.
209       
210        - Improved pkturnkey's general usability.
211       
212        - Added a manpage for pkturnkey.
213       
214    - 1.23alpha24 :
215   
216        - Allows different databases to be used depending on the
217          user's rights. This allows PyKota admins to directly
218          use a master LDAP server for read+write, while letting
219          normal users using the replicas for readonly access.
220          NB : using different storage backends is also possible,
221          but you're on your own there.
222         
223    - 1.23alpha23 :
224   
225        - Fixed a problem with banner accounting.
226   
227        - Introduction of the new 'pkturnkey' command line tool.
228       
229    - 1.23alpha22 :
230   
231        - The cupspykota backend was almost entirely rewritten from scratch.
232          It's now much more readable, maintainable, etc...
233         
234        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
235          advised to download earlier releases or purchase the
236          PyKota v1.22HotFix1 Official release. LPRng support
237          MIGHT be re-added later.
238       
239    - 1.23alpha21 :
240     
241        - Fix for IPP requests which contain more than a single
242          job-originating-host-name attribute.
243         
244    - 1.23alpha20 :
245   
246        - Added the overwrite_jobticket directive. See pykota.conf.sample
247          for how to use it.
248         
249    - 1.23alpha19 :
250   
251        - Fixed an LDAP filtering problem when managing billing codes.
252       
253        - Added the unknown_billingcode directive. See pykota.conf.sample
254          for how to use it.
255       
256    - 1.23alpha18 :
257     
258        - Added the dump_bfd.php contribution.
259       
260        - Several fixes in the internal PJL accounter.
261       
262        - Now autopykota doesn't create unneeded print quota entries anymore.
263       
264        - Increased the timeout in the PJL hardware accounting code to
265          accomodate some printers (HP5000 at least).
266         
267    - 1.23alpha17 :
268   
269        - pkpgcounter is now distributed separately only. This
270          means that people must now download and install pkpgcounter
271          v1.56 or higher prior to being able to run PyKota.
272         
273        - Removed all the autoconf/automake stuff which was outdated 
274          and confusing.
275         
276    - 1.23alpha16 :
277     
278        - Extracted the GPL blurb from all commands' help, and use
279          a static version only once. This saves space big time, and
280          eases future translations.
281         
282    - 1.23alpha15 :
283   
284        - pkbcodes now works with the PostgreSQL backend.
285          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
286       
287    - 1.23alpha14 :
288   
289        - Logs a warning when the user/group doesn't exist when running
290          edpykota.
291         
292    - 1.23alpha13 :
293   
294        - Minor fix for user groups because of latest database changes.
295       
296    - 1.23alpha12 :
297   
298        - Big database changes, use the migration scripts !
299       
300    - 1.23alpha11 :
301   
302        - Small fix to the PCL3/4/5 parser for some drivers.
303       
304    - 1.23alpha10 :
305   
306        - Fixed a bad exception name in cupspykota when parsing IPP messages.
307       
308        - Improved the IPP messages module : it can now generate IPP messages
309          in addition to parsing them.
310       
311    - 1.23alpha9 :   
312   
313        - The denyduplicates directive now accepts a command line as an
314          argument beside yes/no. The command is launched and must
315          print either ALLOW or DENY to its standard output. Then the
316          job gets allowed or denied by PyKota.
317          This will allow user interaction in the near future.
318         
319        - Introduced the new 'striptitle' directive to remove ugly prefixes
320          from print job's titles whenever a new print job is submitted.
321         
322        - Fixed internal SNMP accounter for printers which only have a life time
323          page counter, and not a volatile page counter.
324         
325    - 1.23alpha8 :
326   
327        - The data dumper can now summarize payments and history with the
328          help of the --sum command line option (or checkbox in the CGI).
329         
330        - The message used when the job's filename, title and options are
331          hidden because of the privacy directive is now translated at
332          retrieval time, instead of at saving time.
333         
334        - Minor fix in the LDAP backend code. 
335         
336    - 1.23alpha7 :
337   
338        - Improvements to the internal PJL and SNMP accounter : now should
339          support more printers and waste less time.
340         
341    - 1.23alpha6 :
342   
343        - The data dumper's start= and end= date filtering options now
344          accept a positive or negative offset to be added to the special
345          keywords 'yesterday', 'today', 'now', 'tomorrow'.
346          e.g. : dumpykota --data history start=yesterday-5 end=today
347         
348    - 1.23alpha5 :
349   
350        - The data dumper's start= and end= date filtering options now accept
351          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
352         
353    - 1.23alpha4 :
354   
355        - The data dumper now accept start= and end= to specify the starting
356          and ending dates to dump the history.
357         
358    - 1.23alpha3 :
359   
360        - The destination link for the logo used in CGI scripts is
361          configurable.
362         
363        - Data dumper improved : it's faster and now datas are correctly
364          escaped.
365       
366        - The URL to the logo displayed in the CGI scripts is configurable.
367       
368    - 1.23alpha2 :
369   
370        - Fixed edpykota --prototype with balance.
371       
372        - Major rewrite of the IPP message parsing code to definitely
373          fix the job-originating-hostname IPP attribute problem.
374       
375    - 1.23alpha1 :   
376   
377        - Sets current username to the user CUPS runs as instead of "root"
378          when printing test pages from CUPS' web interface (because
379          the username is empty in this case).
380         
381        - Fix for strange values in job-originating-hostname
382       
383    - 1.22 :
384

390       
391        - Fixed a permission problem in pykotme and pykosd.
392       
393        - Fixed an inconsitency between SQL and LDAP backends'
394          behavior in edpykota.
395

403       
404        - Clicking on the billing code in printquota.cgi's job history
405          now shows all jobs matching this billing code.
406         
407        - Fixed the dump in CUPS' page_log format which didn't
408          dump the oldest entry.
409

438          command line.
439         
440    - 1.22alpha3 :
441   
442        - Fixes some case related problems with some LDAP backends.
443       
444        - Fixes some problem for printers which directly go from

446          returning to "idle".
447         
448        - Some permissions settings may have prevented cupspykota
449          from parsing cupsd.conf, this is now fixed.

459          match CUPS format.
460         
461    - 1.22alpha1 :
462   
463        - Import into Subversion.
464       
465    - 1.21 :
466   
467        - Improved documentation.
468       
469        - Improved dependencies checker.
470       
471        - Updated some translation files.
472       
473    - 1.21beta2 :
474   
475        - Fixed an LPRng specific bug.
476       
477        - Several improvements on stability issues with manually modified
478          LDAP trees.
479         
480        - Documentation improvements. 
481       
482    - 1.21beta :
483   
484        - Prepared translation files for next release.
485       
486    - 1.21alpha27 :
487   
488        - Allows software() (no arguments) to the software accounting
489          directive. This saves a lot of CPU since the job is not

492         
493        - epykota's --prototype option now works fine with accounts
494          limited by balance.

501       
502        - Fixed some database related glitches.
503       
504    - 1.21alpha25 :
505   
506        - The job's size is now always precomputed, even when
507          'enforcement' is not set to 'strict'.
508         
509        - Introduction of the new 'trustjobsize' configuration directive
510          to workaround some problematic printers. See the sample
511          configuration file for details.
512         
513    - 1.21alpha24 :
514   
515        - Big database structure changes. An upgrade script
516          is now included for PostgreSQL. LDAP users may just
517          want to copy the new schema in place.
518         
519        - edpykota now recognizes the -o | --overcharge command line
520          option to set an overcharging or undercharging factor
521          on each print job's cost for a particular user.
522         
523        - repykota's output format has changed an is not limited to 
524          80 characters wide anymore. People who used to parse
525          repykota's output in their own tools are strongly advised
526          to parse dumpykota's output instead.
527         
528        - Introduction of the new 'maxdenybanners' configuration directive
529          to allow up to N (the directive's value) deny banners to be
530          printed even if the print account is forbidden to print.
531         
532        - Better detection of the number of copies in the PostScript parser.
533

543          '*' to be the default argument anymore :-)
544         
545    - 1.21alpha21 :
546   
547        - dumpykota.cgi can now be run as a normal user as opposed to
548          a PyKota administrator. No read access to pykotadmin.conf is
549          necessary anymore. This CGI scripts now honors the REMOTE_USER
550          environment variable just like printquota.cgi does, see
551          the file cgi-bin/README for details.
552          The command line tool dumpykota must still be run by a PyKota
553          administrator.
554         
555        - Fix exception's name error due to a change in recent versions
556          of PygreSQL.

559         
560        - Big bug fix wrt the datelimit field which was never reset.
561         
562    - 1.21alpha19 :
563   
564        - Introduction of the new dumpykota.cgi CGI script, which
565          allows third party tools like phpPrintAnalyzer to be
566          interfaced in real time with PyKota. To use it you
567          may have to change your web server's configuration,
568          please see pykota/cgi-bin/README
569         
570    - 1.21alpha18 :
571   
572        - Now dumpykota can dump the job history into CUPS' page_log
573          format (even when the printing system is LPRng). This allows
574          people to use tools like PrintAnalyzer or phpPrintAnalyzer
575          (two completely different beasts) with PyKota.
576         
577    - 1.21alpha17 :
578     
579        - Fixed field type's name in XML dumps.
580

594          in dumpykota's output.
595         
596        - dumpykota filtering capabilities are now supported within
597          the LDAP backend too.
598         
599    - 1.21alpha14 :
600   
601        - dumpykota now supports extended filtering possibilities
602          with the PostgreSQL backend (LDAP support will come soon).
603         
604    - 1.21alpha13 :
605   
606        - Added a --debug command line option to pkpgcounter, so
607          that people may see what really happens, and what will
608          be available in the future :-)
609         
610    - 1.21alpha12 :
611   
612        - Fixed a bug with non standard pkbanner command lines.
613

618   
619        - Now user and group print quota entries can be stored directly
620          below the user or group with the LDAP backend, using them
621          as branches. Thanks to Stefan Wold for the patch.
622          See the sample configuration file for details.
623         
624        - TLS is now supported with the LDAP backend. Thanks to Stefan
625          Wold for the patch.
626          See the sample configuration file for details.
627         
628        - edpkota now accepts the -U | --used value command line argument
629          to preset the page counters to an initial value. Thanks to
630          Wilson Roberto Afonso and Matt Hyclak for the patch.
631         
632    - 1.21alpha10 :
633   
634        - Now automatically reconnects up to three times if the LDAP server
635          returned an error, possibly due to a timeout.
636         
637    - 1.21alpha9 :
638   
639        - Now searches the configuration files in 'pykota' system user's
640          home directory. The 'pykota' system user and group have
641          to be created by the system administrator, and given
642          sufficient permissions to PyKota's configuration files.
643         
644    - 1.21alpha8 :
645   
646        - Added the new reject_unknown directive to reject the

674    - 1.21alpha3 :
675   
676        - PyKota can now generate its own banners, and either account

686         
687    - 1.21alpha1 :
688   
689        - added an IPP messages miniparser. Extraction of the client
690          hostname is now considered to be fiable, at least until
691          the CUPS developpers change something...
692       
693    - 1.20 :
694   
695        - Version number changed.
696       
697    - 1.20beta :

709        - Minor changes in the debian directory.
710       
711    - 1.20alpha27 :
712   
713        - Fixed many problems with translation files. In particular
714          the Brazilian Portuguese translation file was incorrectly
715          installed into the french "breton" locale directory.
716         
717        - Finished French translation. 
718         
719    - 1.20alpha26 :
720   
721        - LPRng support code should now better detect network
722          printers' hostnames or IP addresses.

726        - Fix for incorrect locale setting when starting.
727       
728    - 1.20alpha25 :
729   
730        - pkprinters allows --list to normal users, but require user
731          to be a PyKota administrator when another command line
732          option is used.
733         
734        - pkhint doesn't use absolute path to search for helper commands
735          anymore.
736         
737        - Spanish translation ready for 1.20.   
738       
739    - 1.20alpha24 :
740   
741        - Now warnpykota only warns users limited by balance once.
742       
743        - Now warnpykota only warns users who have ever printed,
744          to not cause confusion to users who have just opened
745          their account.
746       
747        - Prepared help messages for translations.
748       
749    - 1.20alpha23 :
750   
751        - Add workaround for locale problem.
752       
753    - 1.20alpha22 :
754   
755        - Hopefully final fix for data encoding charset.
756       
757        - edpykota now refuse to work if the user is not a PyKota admin.
758       
759        - Fixes a recently introduced bug with users groups and PostgreSQL.
760       
761    - 1.20alpha21 :
762   
763        - Now dumpykota refuses to launch if the current user is not
764          a PyKota administrator (a PyKota administrator is an user
765          allowed to read the pykotadmin.conf file).
766         
767        - Now any PyKota administrator can use repykota and warnpykota
768          with additionnal arguments, not only the root user.
769         
770        - Improved documentation a bit.
771       
772    - 1.20alpha20 :

782       
783        - Finished implementation of LDAP support in dumpykota.
784       
785        - The md5 sum of the job's datas is now available as an
786          hexadecimal digest in the PYKOTAMD5SUM environment variable.
787         
788        - The description, filename, title, and options fields
789          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
790          Proper charset is used during extraction from the database.
791         
792    - 1.20alpha18 :
793   
794        - Experimental autopykota command to initialize user
795          account and quota entries on first print while not
796          resetting the balance value if not needed.
797         
798        - Added the new "winbind_separator" directive to strip
799          out the Samba/Winbind domain name while printing if
800          needed (Off by default).
801         
802    - 1.20alpha17 :

810   
811        - Internal handling of socket based PJL queries over
812          port tcp/9100 is now available with the magic
813          'pjl' value in the hardware accounter.
814         
815    - 1.20alpha15 :
816   
817        - LDAP pykotaAccountBalance objects were always created
818          attached to the pykotaUser objects. This is now
819          fixed and the value of balancebase in pykota.conf
820          is now correctly used.
821         
822    - 1.20alpha14 :
823   
824        - Belgian translations added (copy of the french ones).

829        - pkhint now suggest the internal snmp handling instead
830          of the external one.
831         
832    - 1.20alpha13 :
833     
834        - Hardware accounter now accepts the special
835          'snmp' value, meaning ALL is done from main code
836          without launching any subprocess.
837          You need the http://pysnmp.sf.net Python module
838          for this to work (tested with v3.4.2)
839         
840        - Increased delay between two loops iterations 
841          to 2 seconds in waitprinter.sh to diminish
842          CPU load.
843         
844    - 1.20alpha12 :
845   
846        - waitprinter.sh rewritten from scratch to wait
847          for printer status stabilization.
848       
849    - 1.20alpha11 :
850   
851        - Generic data dumper 'dumpykota' introduced.
852          Works only with PostgreSQL backend for now.
853         
854    - 1.20alpha10 :
855   
856        - Added fix for incorrect job's size computation when
857          hardware accounting fails.
858

867       
868    - 1.20alpha7 :
869   
870        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
871          Needs more work, but no documentation is available.

873    - 1.20alpha6 :
874     
875        - Improved mailandpopup.sh script.
876       
877        - Small fixes for LPRng.
878       
879        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
880          hostname or IP address. Set to 'localhost' when not
881          meaningful.
882         
883        - Fixed issue with how mod_auth_ldap Apache modules
884          fills the REMOTE_USER environment variable.
885         
886        - Fixed a bug in LDAP user deletion code.
887       
888    - 1.20alpha5 :
889     
890        - Introduces the new configuration directive 'onaccountererror'
891          to specify what must be done whenever the software or
892          hardware accounter fails. Allowed values are 'continue' and
893          'stop' (default).
894         
895        - Minor fix in software accounter for a recently introduced
896          problem.
897         
898    - 1.20alpha4 :
899   
900        - Added support for more ghostscript devices in ESC/P2
901          analyzer : stcolor, st800, escp, escpc are now supported.
902         
903    - 1.20alpha3 :
904       
905        - Small improvement in PostScript parser to avoid being
906          fooled by a change in number of copies :
907          The user can't ask for 200 copies of page 1 and 1 copy
908          of page 2 to fool PyKota anymore :
909          this would have been accounted for as 1 copy only, but
910          now the maximum value seen is used.
911         
912        - Relax checks for PCL5 header to accomodate some strange
913          printer drivers.
914         
915        - Now hardware accounting method works like software
916          accounting method wrt the subprocess' output.
917         
918        - Hardware and Software accounting stop the print queue 
919          when the accounting subprocess didn't work. This will
920          be configurable in the near future.
921         
922    - 1.20alpha2 :
923   
924        - Now software accounting method reads accounter's
925          answer until a line with a single integer is
926          obtained or until all of its output has been read.
927          This should fix the problem some people have
928          when strange locale related messages are sent
929          when running subprocesses (Solaris only ?).
930         
931        - First version of ESC/P2 analyzer. Seems to work
932          ok at least with 'epson', 'epsonc', 'eps9mid'
933          and 'esp9high' ghostscript devices. Needs more
934          work to correctly analyze other devices.
935       
936    - 1.20alpha1 :
937   
938        - Fixed problem with number of copies in PCLXL parser.
939       
940        - Fixed problem with number of copies in PCL5 parser,
941          when number of copies was set outside of and before first
942          page.
943       
944        - Added workaround for number of copies directly set in
945          PostScript code.
946         
947        - Added german translation.
948       
949        - Fixed problem on first print for user group quota when
950          "enforcement: strict" is used.
951       
952        - Fixed interpolation problem in french translation.
953

957       
958        - Added final Thai and Greek translations.
959       
960        - Minor last minute bug fixes.
961       
962    - 1.19beta :
963   
964        - LPRng support for both software and hardware accounting seems
965          to be OK.
966         
967        - Translation files fixed because of fuzzy matching problem. 
968       
969        - Fixed path to Swedish translation: 'sv' instead of 'se'.
970       
971        - Added first draft of Thai translation.
972       
973        - Fixed some minor bugs with Pychecker.
974       
975    - 1.19alpha35 :
976   
977        - Generic PDL analyzer now supports Binary PostScript documents
978          in addition to DSC compliant ones.
979       
980    - 1.19alpha34 :
981   
982        - LPRng support : software accounting seems to work fine,
983          but hardware accounting doesn't work yet.
984   
985    - 1.19alpha33 :
986   
987        - pykosd now accepts command line arguments. Enjoy !
988          NB : due to a bug in xosd, you need xosd version 2.2.8
989          or higher if you don't use the default C locale.
990         
991    - 1.19alpha32 :
992   
993        - Early (not working) version of the LPRng support rewrite.
994       
995        - Saner default configuration file.
996       
997    - 1.19alpha31 :
998   
999        - Fixed a double Python2.1 incompatibility with newer versions,
1000          which prevented the PCL5 and the PCLXL parsers to work with
1001          this older version of Python.
1002         
1003    - 1.19alpha30 :
1004   
1005        - Introduction of preliminary version of the pykosd command
1006       
1007        - Usernames, Groupnames and Printernames can now contain
1008          ANY character, expected '/' and '@'.
1009       
1010        - Integrated most of the Debian work from Sergio
1011          Gonz�z Gonz�z
1012         
1013    - 1.19alpha29 :
1014   
1015        - PCLXL parser should now correctly handle number of
1016          copies set for each page.
1017         
1018        - Added testsuite for generic PDL analyzer.
1019       
1020        - Typo fixed in PCLXL parser.
1021       
1022        - Correctly dispatches error messages depending on the
1023          situation : tools which can be run interactively will
1024          ALWAYS output their logs to stderr, excepted for
1025          their DEBUG messages, for which the "logger:"
1026          directive as set in pykota.conf will be honored.
1027          Tools which can't be run interactively will ALWAYS
1028          honor the "logger:" directive as set in pykota.conf
1029         
1030    - 1.19alpha28 :
1031   
1032        - The description field for printers can now be set,
1033          and is displayed in reports.
1034         
1035        - Fixed a small problem in SQL backend code.
1036         
1037        - Improved pkhint
1038       
1039        - First working PCL6 (aka PCLXL) parser !
1040          Doesn't handle copies yet.
1041       
1042    - 1.19alpha27 :
1043   
1044        - Additionnal 10% speed increase in PCL5 parser for GhostScript
1045          generated files (untested yet with other PCL files).
1046         
1047        - Reintroduced the use of mmap in PCL5 parser : this speedups
1048          PCL5 parsing by almost 4 times.
1049          This 4x with the 3x below give us in fact a twelvefold increase
1050          in performance for PCL5 parsing !
1051         
1052        - The Python accelerator Psyco is now used if available
1053          in the generic PDL parser : it speedups PCL5 parsing by
1054          almost three times automagically.
1055         
1056    - 1.19alpha26 :
1057   
1058        - Fixed PCL5 parser according to the sources of rastertohp.
1059       
1060        - Fixed number of copies handling in PCL5 parser : the number
1061          of copies could vary from page to page.
1062         
1063        - Added more debug information to PCLXL parser. 
1064       
1065    - 1.19alpha25 :
1066   
1067        - Added new "description" field to printers in both
1068          PostgreSQL and LDAP. No code to handle this yet.
1069         
1070        - Reversed the fix for power save mode in printers : 
1071          no paper or tray open would have caused people to
1072          be undercharged.
1073         
1074        - Preliminary version of MySQL initialization script.
1075         
1076    - 1.19alpha24 :
1077   
1078        - Native PDF parsing code now works perfectly with
1079          Python 2.1 and above, and is way faster than before.
1080          GhostScript is not used anymore to convert PDF to PS,
1081          because PDF is parsed directly.
1082         
1083    - 1.19alpha23 :
1084   
1085        - Fixed waitprinter.sh wrt PowerSave mode and some
1086          printers. Thanks to Ryan Suarez.
1087       
1088        - Smart PDL analyzer now recognizes PDF too : two
1089          PDF parsing methods are used : a native one which
1090          is very fast but requires Python 2.3 or above, and
1091          a slower one which uses Ghostscript. PyKota detects
1092          automatically which method to use depending on your
1093          version of Python.
1094       
1095        - All tracebacks now include PyKota's version number.
1096         
1097    - 1.19alpha22 :
1098   
1099        - Ensures that the file pointer for job's data is
1100          reset to the start of the job's datas after the
1101          job's size pre-computation phase.
1102         
1103        - Improved PostScript detection code for bad drivers
1104          which don't correctly switch languages between PJL
1105          and PS.
1106       
1107        - Even better debugging code.
1108       
1109    - 1.19alpha21 :
1110   
1111        - Additionnal check.
1112       
1113    - 1.19alpha20 :
1114   
1115        - More complete logging messages wrt accounters.
1116       
1117        - Now catches early failures occuring when the configuration
1118          files are parsed.
1119       
1120    - 1.19alpha19 :
1121   
1122        - Fixed over-verbose exits when displaying help
1123          or version.
1124         
1125        - Extended some PATH in the shell scripts 
1126       
1127        - Deleting an user now also deletes his payments history.
1128       
1129        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
1130          cause problems.
1131
1132    - 1.19alpha18 :
1133   
1134        - History of payments is now stored in the database, and
1135          updated each time an user's balance is modified with
1136          edpykota --balance. This history represents each time
1137          the user was given some positive or negative credit,
1138          but doesn't reflect price paid for jobs, which appear
1139          in the jobs history instead.
1140         
1141        - Jobs history web reports now include the job's size in
1142          bytes. Also columns were reordered to render the report
1143          more easily readable.
1144         
1145    - 1.19alpha17 :
1146   
1147        - Mysterious bug (program exited unexpectedly without leaving
1148          any log message) which occured once in a while when
1149          cancelling jobs should be fixed now.
1150         
1151        - New 'crashrecipient' directive. Disabled by 
1152          default. See sample configuration file to see how
1153          to activate it. It is suggested that you activate it.
1154         
1155        - New PYKOTAJOBSIZEBYTES environment variable exported, 
1156          which contains the job's size in bytes. Empty jobs
1157          are now denied. This value is now stored in the job
1158          history (but not yet displayed from the web interface)
1159         
1160        - Preliminary work on payments storage : the PostgreSQL 
1161          and LDAP schemas should be OK now, but no code is written
1162          yet to support this functionnality.
1163         
1164    - 1.19alpha16 :
1165   
1166        - the newuser and newgroup LDAP specific directives now accept
1167          a second parameter to attach(), "fail" or "warn". If no entry
1168          is found to attach PyKota attributes to, and "fail" was used,
1169          then action is aborted and program exits in error. If "warn"
1170          is used, a new entry is created but a warning message is logged.
1171         
1172        - The job's originating hostname is now stored in the database,
1173          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
1174       
1175    - 1.19alpha15 :
1176   
1177        - The old pykota filter is now removed. This means that
1178          currently PyKota doesn't support LPRng anymore, but
1179          LPRng support will be re-added, improved, in the near future.
1180         
1181    - 1.19alpha14 :
1182   
1183        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
1184          are now exported as environment variables.
1185         
1186        - Heavy CPU usage is now completely fixed it seems, by
1187          introducing some 0.01 second sleeping when nothing to do.
1188         
1189        - Pre-computation of the job's size is now only
1190          done when enforcement is "STRICT", this saves
1191          CPU for people who don't want to use this new
1192          feature.
1193         
1194        - New 'enforcement' directive which accepts either
1195          STRICT or LAXIST. See sample configuration file
1196          for details.
1197         
1198    - 1.19alpha13 :
1199   
1200        - Get back to an old version of the polling loop which
1201          worked fine, but non-optimally. Will be optimized
1202          as time permits.
1203         
1204    - 1.19alpha12 :
1205   
1206        - Job's size is now precomputed unconditionnally using
1207          the generic PDL analyzer.
1208          NB : This value is not yet used to pre-allow/deny the
1209          job.
1210       
1211    - 1.19alpha11 :
1212   
1213        - The pykota filter is now completely deprecated and
1214          can't be used anymore. LPRng users MUST download
1215          an older version of PyKota. CUPS users MUST use
1216          cupspykota. Better support for LPRng will come
1217          in the near future.
1218         
1219    - 1.19alpha10 :
1220   
1221        - pykotme now uses generic PDL Analyzer directly instead
1222          of spawning a new process.
1223         
1224        - Improvements to generic PDL Analyzer.
1225       
1226        - 25% Speedup in PCL parser. Getting more of the Python version
1227          will probably be difficult, since the completely table driven
1228          parser I wrote is slower than the original algorithm. Then,
1229          the original algorithm is still used for now.
1230          Probable that more speed could be achieved using mmap, at the
1231          expense of severe memory consumption.
1232       
1233        - configuration simplifications : the "accounter" directive's
1234          'hardware' arguments now accepts what was in the "requester"
1235          directive as it's content. The "requester" directive is not
1236          supported anymore. See sample configuration file for details.
1237       
1238    - 1.19alpha9 :
1239       
1240        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1241       
1242        - pykotaOptions LDAP attribute now accepts non-ascii characters
1243          too.
1244         
1245        - First try at cupspykota main loop rewrite
1246       
1247    - 1.19alpha8 :
1248   
1249        - 'querying' accounting method is now called 'hardware'
1250       
1251        - 'external' accounting method is now called 'software'
1252       
1253        - 'stupid' accounting method doesn't exist anymore
1254       
1255        - 'snmp' requester doesn't exist anymore
1256       
1257        - code simplifications in external requester
1258       
1259    - 1.19alpha7 :
1260     
1261        - Database schema change (both LDAP and PostgreSQL) to
1262          allow storage of the job-originating-hostname attribute.
1263          An SQL upgrade script is present. The code is not yet
1264          capable of setting/retrieving this attribute. Support
1265          for this functionnality will be added in the future.
1266         
1267    - 1.19alpha6 :
1268   
1269        - problems connecting to SMTP servers are now catched.
1270       
1271        - pykotme now uses pkpgcounter to compute the size of the
1272          job. This modification adds PCL5 and soon PCLXL (PCL6)
1273          support. You can now get quotes for PCL in addition to
1274          PostScript.
1275         
1276        - pkpgcounter now includes first try at PCLXL parser. 
1277          It is currently disabled until it's finished.
1278         
1279    - 1.19alpha5 :
1280   
1281        - cupspykota polling loop fix for MacOSX (at least)
1282       
1283        - logging subsystem now logs PID too, to ease diagnosing
1284          problems under heavy load.
1285         
1286        - pkpgcounter enhancements.
1287       
1288        - pkprinters --skipexisting now tells pkprinters to not
1289          modify existing printers when --add is used.
1290          pkprinters logs a warning message whenever --add is
1291          used and a printer already exists.
1292         
1293        - LDAP schema now allows accented chars in pykotaFileName
1294          and pykotaTitle attributes.
1295       
1296    - 1.19alpha4 :
1297   
1298        - a bad copy&paste prevented pkpgcounter to work at all, this
1299          is now fixed.
1300         
1301        - improved PCL support in pkpgcounter, with the use of
1302          HP PCL/PJL Reference Set
1303          PCL5 Printer Language Technical Quick Reference Guide
1304       
1305        - pkpgcounter now uses mmap to speed things up : duration
1306          is halved with the sample 87 pages PCL document I use for
1307          testing.
1308         
1309    - 1.19alpha3 :
1310   
1311        - pkprinters now accepts the --list command line argument
1312          to list informations about printers.
1313         
1314    - 1.19alpha2 :
1315   
1316        - pkpgcounter is now included as a smart external
1317          accounter which can handle both PostScript and PCL.
1318         
1319    - 1.19alpha1 :
1320   
1321        - PYKOTALIMITBY environment variable is now exported too.
1322       
1323        - Inclusion of Michele Baldessari's work on autotools.
1324       
1325    - 1.18 :
1326   
1327        - Improved documentation
1328       
1329    - 1.18beta2 :
1330     
1331        - Fix for raw jobs with cupspykota
1332       
1333    - 1.18beta :
1334   
1335        - Small fix for new waitprinter.sh script
1336       
1337        - Better tracebacks on error conditions
1338       
1339        - Improved translations
1340       
1341        - Improved documentation
1342       
1343    - 1.18alpha15 :
1344
1345        - waitprinter.sh replaced by a new and possibly faster
1346          and more powerful one.
1347   
1348        - Names can now begin with a digit.
1349       
1350        - Stability improvement for quotas set on printers groups.
1351       
1352    - 1.18alpha14 :
1353   
1354        - Catches more (all ?) problems with SMTP servers instead
1355          of breaking.
1356         
1357        - Italian translation added.
1358       
1359    - 1.18alpha13 :
1360   
1361        - Pre and Post hooks are now available in the pykota
1362          filter as well.
1363         
1364        - The pykota filter doesn't check last user's quota
1365          anymore when delayed hardware accounting is used :
1366          this will be done anyway the next time the last
1367          user will print again. This saves some database
1368          queries which are unneeded.
1369       
1370    - 1.18alpha12 :
1371   
1372        - Pre and Post hooks to external commands with many
1373          many environment variables available are useable
1374          from the cupspykota backend.
1375          See sample configuration file for details and help.
1376         
1377    - 1.18alpha11 :
1378   
1379        - Hopefully final fix wrt groups (users and printers)
1380       
1381    - 1.18alpha10 :
1382   
1383        - Fixed nested printer groups accounting.
1384       
1385        - Fixed user groups + printer groups problem.
1386       
1387    - 1.18alpha9 :
1388   
1389        - Fix for LDAP problem when job price was 0.
1390       
1391        - Fix for empty user groups with LDAP.
1392       
1393        - Preliminary version of the snmpprinterstatus command added.
1394       
1395    - 1.18alpha8 :
1396   
1397        - Don't retrieve data when not needed.
1398          This avoids many database queries.
1399       
1400    - 1.18alpha7 :
1401   
1402        - New experimental ldapcache directive to improve
1403          LDAP caching.
1404         
1405    - 1.18alpha6 :
1406       
1407        - New configuration directive added : maildomain
1408          to specify the domain to send mail to when user
1409          email address is not set in PyKota database.
1410         
1411        - More complete email message headers. 
1412         
1413    - 1.18alpha5 :
1414   
1415        - Debian packaging specific files, contributed by
1416          Peter Hawkins are now included in the project's tree.
1417         
1418        - Preliminary work on future low-level LDAP caching to speed
1419          up modifications (at least).
1420         
1421    - 1.18alpha4 :
1422   
1423        - Applied some of the modifications suggested by
1424          Peter Hawkins, for better Debian integration.
1425          Most notably cupspykota, pykota, and the shell
1426          scripts are now installed into /usr/share/pykota
1427          instead of into /usr/bin
1428          BEWARE : double check that your symbolic link
1429          to cupspykota is correct, and that your pykota.conf
1430          file use correct path for the shell scripts like
1431          waitprinter.sh and al.
1432         
1433        - pkhint command added, to help in configuring correct
1434          accounting method for PyKota.
1435         
1436    - 1.18alpha3 :
1437   
1438        - Fixed a rare bug in cupspykota backend which gave
1439          incorrect "CUPS backend died abnormally" messages.
1440       
1441    - 1.18alpha2 :
1442   
1443        - Added the pkprinters command line tool to manage printers
1444          exclusively.
1445       
1446    - 1.18alpha1 :
1447   
1448        - Preliminary work on Relationnal Database Independance.
1449       
1450        - Sample report made from OpenOffice.org added as PDF and SXC.
1451       
1452    - 1.17 :
1453   
1454        - Finalized release.
1455       
1456    - 1.17alpha2 :
1457   
1458        - Fix stupid software accounting bug in the CUPS backend.
1459       
1460    - 1.17alpha1 :
1461   
1462        - User/Group deletion code in edpykota rewritten.
1463       
1464    - 1.16 :

1471          though.
1472       
1473        - Portuguese Portuguese translation replaces Brazilian
1474          Portuguese Translation. Brazilian portuguese
1475          translation is still available under the 'br' locale.
1476       
1477    - 1.16beta3 :
1478

1486          printing in CUPS backend.
1487         
1488        - Big fix wrt printing policies for unknown users.

1495   
1496        - Job price is now computed like this :
1497       
1498          SUM((NbPages * PricePerPage) + PricePerJob)
1499         
1500          For current printer and all the printers groups it is
1501          a member of, if any.
1502         
1503          This may be difficult to grasp, but offers unprecedented
1504          flexibility.

1544       
1545    - 1.16alpha18 :
1546   
1547        - Initial code for printer groups support. Printer groups have
1548          to be added with external tools like psql or gq for example.
1549          Printer groups seems to work fine with users. Untested with user
1550          groups for now.
1551
1552        - Several minor visual problems fixed in reports.
1553       
1554        - Fixed a bug in LDAP date handling.

1560          for details.
1561       
1562        - Several environment variables are now exported when executing
1563          external commands (accounters, requesters, mailers) :
1564           
1565            PYKOTAUSERNAME => user who is printing
1566            PYKOTAPRINTERNAME => printer on which the job is being sent
1567            PYKOTATITLE => Job's title
1568            PYKOTAFILENAME => Job's filename
1569            PYKOTACOPIES => number of copies asked
1570            PYKOTAOPTIONS => print command options (-o with CUPS)
1571         
1572    - 1.16alpha17 :
1573   
1574        - Added portugues translation.
1575       
1576        - Major code refactoring in accounters.
1577

1581          have nice looking and useful web based reports (in the future).
1582       
1583        - Added utolower configuration option to convert all usernames
1584          to lowercase during printing.

1592   
1593        - Now printing on a printer not defined in the Quota Storage,
1594          results in the job being cancelled or stopped, depending
1595          on the printing system.
1596         
1597    - 1.16alpha13 :
1598   
1599        - Small bugfix wrt Python v2.1
1600       
1601        - If username is an empty string, user root is assumed.
1602       
1603        - 'postgresql' is not recognized anymore as a storage backend,
1604          you have to use 'pgstorage' instead. 'postgresql' used to
1605          be supported for compatibility with very old PyKota versions,
1606          this is not the case anymore.
1607         
1608    - 1.16alpha12 :
1609   
1610        - Job price added to job history, to keep accounting correct
1611          if a printer price per page or per job is modified and the
1612          history is not reset : the history would have given a false
1613          amount of money charged before the printer's prices were
1614          modified, this addition solves the problem.
1615         
1616    - 1.16alpha11 :
1617   
1618        - Some preliminary modifications to the database structure for
1619          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1620          database is now provided. LDAP attributes now support
1621          eq, pres and sub indexes.
1622         
1623        - Job history now contains additional informations : 
1624          number of copies, filename, title and print options.
1625         
1626    - 1.16alpha10 :
1627       
1628        - Some modifications done to external policy handling.
1629          See sample configuration file for details.
1630   
1631        - Spanish translation added.
1632       
1633    - 1.16alpha9 :
1634   
1635        - mailto can be set to external(...) to warn users above
1636          quota with any command of your choice (e.g. linpopup).
1637          Several parameters are available, see sample configuration
1638          file for details.
1639         
1640    - 1.16alpha8 :
1641   
1642        - Now cupspykota transmits SIGTERMS to the original 
1643          backend when the user deletes a job being processed.
1644

1650        - The CUPS backend is now fully functionnal (it seems).
1651       
1652        - From now on, the use of the pykota filter with CUPS
1653          is deprecated. The pykota filter still has to be
1654          used with LPRng though.
1655       
1656    - 1.16alpha6 :
1657   
1658        - Bug fixed : when edpykota was used to add a printer
1659          with no user or group name, a bad user/group name "*" was
1660          added to the database.
1661         
1662    - 1.16alpha5 :
1663   
1664        - New CUPS backend supports device enumeration !
1665          This means that NO manual CUPS configuration has to
1666          be done. All can now be done from CUPS web interface.
1667       
1668    - 1.16alpha4 :
1669   
1670        - New CUPS backend added.
1671

1693          names or wildcards, separated with commas.
1694         
1695    - 1.15alpha9 :
1696   
1697        - External policy can be used to auto-add unknown users
1698          and any other interesting things you may want to do.
1699          WARNING : You can't auto-add printers for now.
1700          They have to be created manually before.
1701          Look at sample configuration file for examples.
1702         
1703    - 1.15alpha8 :
1704   
1705        - Job history can be disabled if needed.
1706          This feature may be useful for people who use the LDAP
1707          backend and don't want their LDAP tree to grow out of
1708          control.
1709       
1710    - 1.15alpha7 :
1711   
1712        - More work done on caching wrt groups.

1722    - 1.15alpha4 :
1723   
1724        - Problem with Python 2.3 fixed. Needs some definitive
1725          modification.
1726         
1727    - 1.15alpha3 :
1728   
1729        - CGI script now tries to restrict view when the
1730          REMOTE_USER environment variable is set. This allows
1731          people to protect its use with .htaccess files.
1732          When unprotected, or if REMOTE_USER is 'root', then
1733          unrestricted access is granted.
1734          NB : REMOTE_USER is automatically set by the web server
1735          (e.g. Apache) when a page with restricted access is viewed.
1736         
1737    - 1.15alpha2 :
1738

1742       
1743    - 1.15alpha1 :
1744   
1745        - Bug fix in SQL code.
1746       
1747    - 1.14 :
1748   
1749        - The PostgreSQL database connection is now always closed before
1750          exit. The LDAP database connection too, but it didn't suffer
1751          from the problem anyway, AFAICT.
1752       
1753    - 1.14beta2 :
1754   
1755        - An LDAP-specific configuration field was introduced, usermail.
1756          Use it to specify which LDAP attribute contains a valid email
1757          address for the user. See sample configuration file for
1758          details.
1759       
1760    - 1.14beta :
1761   
1762        - Two new LDAP-specific configuration fields were introduced,
1763          newuser and newgroup. Use them to specify if you want to add
1764          quota information to existing entries or elsewhere.
1765          See sample configuration file for details.
1766         
1767    - 1.14alpha9 :
1768   
1769        - Documentation improved.
1770       
1771        - pykotme now also prints the user's account balance value
1772          if the user is registered in the Quota Storage and his
1773          limiting factor is "balance".
1774         
1775    - 1.14alpha8 :
1776   
1777        - bin/waitprinter.sh is now included to wait for
1778          SNMP enabled printers to be idle again before
1779          asking for their internal page counter.
1780          See sample configuration file for details.
1781         
1782    - 1.14alpha7 :
1783   
1784        - edpykota now doesn't check if the user/group is above
1785          quota. The check is only done at print time. This
1786          prevents the sending of email messages when creating
1787          user quotas if quota is already reached at creation
1788          time.
1789         
1790    - 1.14alpha6 :
1791   
1792        - Configuration file split and moved to /etc/pykota/pykota.conf
1793          and /etc/pykota/pykotadmin.conf to prevent simple users to
1794          have Read/Write access to the Quota Database.
1795          Don't forget to :
1796         
1797                $ chmod 640 /etc/pykota/pykotadmin.conf
1798               
1799        - storageuser and storageuserpw configuration fields reintroduced
1800          for the same reason.
1801         
1802        - Code cleaning for future implementation of email addresses
1803          support in the PostgreSQL and LDAP backends.
1804         
1805    - 1.14alpha5 :
1806       
1807        - Big bug fixed when changing the prices for a printer
1808       
1809    - 1.14alpha4 :
1810   
1811        - When adding an user, the user itself and its account balance
1812          are now added in the same LDAP entry. Before they were added
1813          as two different LDAP entries.
1814         
1815    - 1.14alpha3 :
1816   
1817        - Email field added to PostgreSQL database. An upgrade script

1827          balance (below 1.0 by default, configurable) are sent
1828          a warning message.
1829         
1830        - All warning messages to users are now configurable. 
1831          NB : Warning messages to the administrator are not.

1903          hints to the LDAP storage backend.
1904         
1905        - Severe database access optimizations were done by
1906          rewriting most of the Quota Storage backends drivers.

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