22PyKota NEWS :
23       
24    - 1.24HotFix2 (2006-05-30) :
25   
26        - Introduced the 'askconfirmation' directive to interact with
27          the end user through any script (pknotify is recommended)
28          and see if he really wants to print when knowing the cost
29          of the job.
30         
31        - Now uses pkipplib if present to directly retrieve the job
32          information from the CUPS server over IPP.
33         
34        - Added a lock to ensure that a single cupspykota backend
35          is processing datas for a particular print queue at any
36          given time.
37         
38        - Now exports more environment variables for the subprocesses.
39         
40        - Fixed some problems with DateTime objects.
41       
42        - Added support for PySNMP v4.x in addition to 3.4.x.
43       
44        - Make the MySQL schema work with old releases of MySQL.
45       
46        - Fixed several character encoding problems.
47         
48        - Ensures that the denied banners counter is properly initialized
49          with relationnal databases.
50         
51    - 1.24 (2006-04-08) :
52   
53        - Improved documentation and packaging stuff.
54       
55    - 1.24beta (2006-03-26) :
56   
57        - Finalized the pknotify command.
58       
59        - Updated the messages catalogs for translations.
60       
61    - 1.24alpha18 (2006-03-15) :
62   
63        - Now uses MIME encapsulation for email messages to avoid
64          some problems with 8 bits messages being rejected.
65         
66    - 1.24alpha17 (2006-03-06) :
67   
68        - Fixed a major problem in the PostgreSQL backend.
69       
70        - pknotify can now check a remote user's name and password.
71       
72    - 1.24alpha16 (2006-03-02) :
73   
74        - Introduced the pknotify command line tool to dialog
75          with remote PyKotIcon applications.
76         
77    - 1.24alpha15 (2006-03-02) :
78       
79        - optimized pkbcodes, pkprinters and pkusers using edpykota as
80          the model.
81       
82        - 'edpykota --list' and 'pkusers --list' are now authorized
83          to mere mortal users, but the list is restricted to informations
84          about the current user.
85       
86        - Extended the functionnality of the 'onbackenderror' directive to
87          allow for configurable retries.
88         
89    - 1.24alpha14 :
90   
91        - Finished optimizations in edpykota and fixed some minor
92          problems with LDAP.
93         
94    - 1.24alpha13 :
95   
96        - Introduced the pkusers command line tool to manage users and 
97          users groups. This command doesn't deal with print quota entries,
98          which continue to be managed through the edpykota command line
99          tool.
100         
101        - Major rewrite and incompatible changes to command line options
102          in edpykota. This command now only deals with print quota
103          entries. Printers, users (or users groups) now have to be created
104          first using pkprinters or pkusers.
105         
106    - 1.24alpha12 :
107   
108        - Introduced the 'duplicatesdelay' directive to specify after
109          which duration two duplicate jobs are not considered duplicate
110          jobs anymore.
111         
112        - Introduced the 'balancezero' directive to specify any value 
113          as the balance limit instead of 0.0. This can allow admins to
114          give a few free credits to users, for example.
115         
116    - 1.24alpha11 :
117   
118        - Huge speed improvements when modifying billing codes and
119          printers.
120       
121        - Both pkbcodes and pkprinters now display the percent done
122          for all actions.
123         
124        - The pkinvoice invoice generator command line utility is now
125          included.
126         
127    - 1.24alpha10 :   
128   
129        - Huge speed improvements when deleting users, printers, and
130          billing codes.
131         
132    - 1.24alpha9 :
133   
134        - Preliminary support for MySQL, thanks to Matt Hyclak.
135       
136    - 1.24alpha8 :
137   
138        - The 'preaccounter' configuration directive was introduced to control
139          which parser to use for precomputation of the job's size. When unset,
140          the internal parser is used just like it was previously. See
141          conf/pykota.conf.sample for more details.
142         
143        - Now subprocesses launched through the overwrite_jobticket directive
144          can also output 'CANCEL', to represent the user's own choice to
145          cancel the print job.
146         
147    - 1.24alpha7 :
148     
149        - pkbanner now handles new print limiting modes correctly.
150       
151        - The cupspykota backend wrapper now accepts to be interrupted
152          with a kill -INT. This causes an immediate and clean abort
153          of the current print job.
154         
155        - Matt Hyclak contributed the possibility to store the printing
156          history in a MySQL database. See the contributed/ directory
157          for details.
158         
159        - Added 2006 to the copyright's years.
160       
161    - 1.24alpha6 :
162   
163        - Fixed internal SNMP and PJL handling code for very fast
164          printers : PyKota didn't see them going from 'idle'
165          to 'printing' to 'idle' again.
166         
167        - Now waitprinter.sh accepts SNMP version number and
168          community name as arguments, thanks to Brandon
169          Holbrook.
170         
171        - Now command line errors and Ctrl+C repectively cause
172          PyKota commands to exit with status -2 and -3.
173         
174    - 1.24alpha5 :
175   
176        - All command line tools now accept -A | --arguments filename.args
177          as a way to bypass the shell's maximal command line size :
178          just put each argument on a line by itself in a file, and
179          pass the file's name as the -A | --arguments command line
180          option's argument. For now this won't be documented in
181          commands' helps.
182         
183        - dumpykota can now dump the complete database in XML
184          format.
185         
186    - 1.24alpha4 :
187   
188        - Added support for the SQLite3 backend.
189          See pykota/initscripts/sqlite/README.sqlite
190       
191    - 1.24alpha3 :
192   
193        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
194          so we regain priviledges before running an external
195          mailto directive.
196       
197    - 1.24alpha2 :
198   
199        - Introduce the "onbackenderror" directive in pykota.conf, to
200          control if the user must be charged or not whenever a real
201          CUPS backend fails. The default value is 'nocharge'.
202          Set it to 'charge' if you think your users can cause a CUPS
203          backend to fail.
204         
205        - Now mark original backends related problems as such in the
206          printing history. Modified printquota.cgi and pykota.css
207          to make them be more visible.
208         
209    - 1.24alpha1 :
210   
211        - Fixed a problem which caused backend errors to be ignored.
212       
213        - The sample LDIF file now contains the two necessary user
214          entries to have an LDAP PyKota Admin and an LDAP PyKota
215          ReadOnly user. The sample configuration files were updated
216          to contain the default passwords used in the LDIF file.
217         
218        - dumpykota is now more strict when checking arguments.   
219       
220    - 1.23 :
221   
222        - Many minor bug fixes and code cleaning.
223       
224        - Improved documentation.
225       
226        - Added Polish translation.
227       
228        - Improved French and Swedish translations.
229       
230    - 1.23beta :
231   
232        - Now the mailto directive is honored in all cases where the job is
233          denied or a warning has to be issued, and the correct reason
234          can be sent back to the user.
235         
236        - The PYKOTAREASON environment variable, if defined, contains the 
237          textual reason why the job was denied or a warning has to be
238          issued.
239       
240    - 1.23alpha31 :
241   
242        - Added support for --maxjobsize, --passthrough and --nopassthrough
243          in pkprinters. These modes are now also honored when printing.
244         
245        - Allows the admin to restrict the number of print queues which will
246          be treated by pkturnkey by passing queues' names as additionnal
247          arguments on pkturnkey's command line.
248         
249        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
250          command line option.   
251         
252    - 1.23alpha30 :
253   
254        - Database changes : you MUST use upgrade-to-1.23.sql again if you
255          use PostgreSQL, or copy the new schema and restart your LDAP
256          server if you use LDAP.
257         
258        - The -C | --comment command line switch was added to edpykota to 
259          attach textual information to modifications done to a user's
260          account balance.
261         
262        - The -l | --limitby command line switch to edpykota was modified 
263          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
264          command's help or manual page for details.
265         
266        - The -i | --ingroups command line switch to repykota allows 
267          PyKota Administrators to only lists members of the specified
268          group or groups (separated with commas).
269         
270        - The -I | --increase command line switch to edpykota allows
271          to increase or decrease page limits.
272         
273        - Added the precomputed job's size and price to the history
274          for controlling purpose.
275       
276    - 1.23alpha29 :
277   
278        - Fixed a small problem with billing codes.
279       
280        - Exports some environment variables earlier, to render the script
281          launched by the overwrite_jobticket directive more powerful.
282         
283        - Now autopykota also creates print quota entries for the user on the
284          printers groups the current printer is a member of.
285         
286    - 1.23alpha28 :
287   
288        - Added users groups management to pkturnkey.
289       
290        - Fixed umask in setup script.
291       
292    - 1.23alpha27 :
293   
294        - Replaced the --dryrun command line option by the --force
295          command line option in pkturnkey, with exactly the opposite
296          effect (for security reasons).
297         
298    - 1.23alpha26 :
299   
300        - Allows parametrized pjl and snmp hardware accounting methods,
301          to be able to respectively set the TCP port and the SNMP
302          community.
303         
304    - 1.23alpha25 :
305   
306        - Added a --dryrun command line switch to pkturnkey.
307       
308        - Improved pkturnkey's general usability.
309       
310        - Added a manpage for pkturnkey.
311       
312    - 1.23alpha24 :
313   
314        - Allows different databases to be used depending on the
315          user's rights. This allows PyKota admins to directly
316          use a master LDAP server for read+write, while letting
317          normal users using the replicas for readonly access.
318          NB : using different storage backends is also possible,
319          but you're on your own there.
320         
321    - 1.23alpha23 :
322   
323        - Fixed a problem with banner accounting.
324   
325        - Introduction of the new 'pkturnkey' command line tool.
326       
327    - 1.23alpha22 :
328   
329        - The cupspykota backend was almost entirely rewritten from scratch.
330          It's now much more readable, maintainable, etc...
331         
332        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
333          advised to download earlier releases or purchase the
334          PyKota v1.22HotFix1 Official release. LPRng support
335          MIGHT be re-added later.
336       
337    - 1.23alpha21 :
338     
339        - Fix for IPP requests which contain more than a single
340          job-originating-host-name attribute.
341         
342    - 1.23alpha20 :
343   
344        - Added the overwrite_jobticket directive. See pykota.conf.sample
345          for how to use it.
346         
347    - 1.23alpha19 :
348   
349        - Fixed an LDAP filtering problem when managing billing codes.
350       
351        - Added the unknown_billingcode directive. See pykota.conf.sample
352          for how to use it.
353       
354    - 1.23alpha18 :
355     
356        - Added the dump_bfd.php contribution.
357       
358        - Several fixes in the internal PJL accounter.
359       
360        - Now autopykota doesn't create unneeded print quota entries anymore.
361       
362        - Increased the timeout in the PJL hardware accounting code to
363          accomodate some printers (HP5000 at least).
364         
365    - 1.23alpha17 :
366   
367        - pkpgcounter is now distributed separately only. This
368          means that people must now download and install pkpgcounter
369          v1.56 or higher prior to being able to run PyKota.
370         
371        - Removed all the autoconf/automake stuff which was outdated 
372          and confusing.
373         
374    - 1.23alpha16 :
375     
376        - Extracted the GPL blurb from all commands' help, and use
377          a static version only once. This saves space big time, and
378          eases future translations.
379         
380    - 1.23alpha15 :
381   
382        - pkbcodes now works with the PostgreSQL backend.
383          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
384       
385    - 1.23alpha14 :
386   
387        - Logs a warning when the user/group doesn't exist when running
388          edpykota.
389         
390    - 1.23alpha13 :
391   
392        - Minor fix for user groups because of latest database changes.
393       
394    - 1.23alpha12 :
395   
396        - Big database changes, use the migration scripts !
397       
398    - 1.23alpha11 :
399   
400        - Small fix to the PCL3/4/5 parser for some drivers.
401       
402    - 1.23alpha10 :
403   
404        - Fixed a bad exception name in cupspykota when parsing IPP messages.
405       
406        - Improved the IPP messages module : it can now generate IPP messages
407          in addition to parsing them.
408       
409    - 1.23alpha9 :   
410   
411        - The denyduplicates directive now accepts a command line as an
412          argument beside yes/no. The command is launched and must
413          print either ALLOW or DENY to its standard output. Then the
414          job gets allowed or denied by PyKota.
415          This will allow user interaction in the near future.
416         
417        - Introduced the new 'striptitle' directive to remove ugly prefixes
418          from print job's titles whenever a new print job is submitted.
419         
420        - Fixed internal SNMP accounter for printers which only have a life time
421          page counter, and not a volatile page counter.
422         
423    - 1.23alpha8 :
424   
425        - The data dumper can now summarize payments and history with the
426          help of the --sum command line option (or checkbox in the CGI).
427         
428        - The message used when the job's filename, title and options are
429          hidden because of the privacy directive is now translated at
430          retrieval time, instead of at saving time.
431         
432        - Minor fix in the LDAP backend code. 
433         
434    - 1.23alpha7 :
435   
436        - Improvements to the internal PJL and SNMP accounter : now should
437          support more printers and waste less time.
438         
439    - 1.23alpha6 :
440   
441        - The data dumper's start= and end= date filtering options now
442          accept a positive or negative offset to be added to the special
443          keywords 'yesterday', 'today', 'now', 'tomorrow'.
444          e.g. : dumpykota --data history start=yesterday-5 end=today
445         
446    - 1.23alpha5 :
447   
448        - The data dumper's start= and end= date filtering options now accept
449          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
450         
451    - 1.23alpha4 :
452   
453        - The data dumper now accept start= and end= to specify the starting
454          and ending dates to dump the history.
455         
456    - 1.23alpha3 :
457   
458        - The destination link for the logo used in CGI scripts is
459          configurable.
460         
461        - Data dumper improved : it's faster and now datas are correctly
462          escaped.
463       
464        - The URL to the logo displayed in the CGI scripts is configurable.
465       
466    - 1.23alpha2 :
467   
468        - Fixed edpykota --prototype with balance.
469       
470        - Major rewrite of the IPP message parsing code to definitely
471          fix the job-originating-hostname IPP attribute problem.
472       
473    - 1.23alpha1 :   
474   
475        - Sets current username to the user CUPS runs as instead of "root"
476          when printing test pages from CUPS' web interface (because
477          the username is empty in this case).
478         
479        - Fix for strange values in job-originating-hostname
480       
481    - 1.22 :
482   
483        - Big improvements to the documentation.

541       
542        - Fixes some problem for printers which directly go from

545         
546        - Some permissions settings may have prevented cupspykota
547          from parsing cupsd.conf, this is now fixed.
548

550   
551        - Introduction of the web enabled print quote generator.
552

584    - 1.21alpha27 :
585   
586        - Allows software() (no arguments) to the software accounting
587          directive. This saves a lot of CPU since the job is not
588          parsed again : the precomputed size is used directly in this
589          case.
590         
591        - epykota's --prototype option now works fine with accounts
592          limited by balance.

606         
607        - Introduction of the new 'trustjobsize' configuration directive
608          to workaround some problematic printers. See the sample
609          configuration file for details.
610         
611    - 1.21alpha24 :
612   
613        - Big database structure changes. An upgrade script
614          is now included for PostgreSQL. LDAP users may just
615          want to copy the new schema in place.
616         
617        - edpykota now recognizes the -o | --overcharge command line
618          option to set an overcharging or undercharging factor
619          on each print job's cost for a particular user.
620         
621        - repykota's output format has changed an is not limited to 
622          80 characters wide anymore. People who used to parse
623          repykota's output in their own tools are strongly advised
624          to parse dumpykota's output instead.
625         
626        - Introduction of the new 'maxdenybanners' configuration directive
627          to allow up to N (the directive's value) deny banners to be
628          printed even if the print account is forbidden to print.
629         
630        - Better detection of the number of copies in the PostScript parser.
631

637       
638    - 1.21alpha22 :
639   
640        - edpykota's --delete command line option doesn't consider
641          '*' to be the default argument anymore :-)
642         
643    - 1.21alpha21 :
644   
645        - dumpykota.cgi can now be run as a normal user as opposed to
646          a PyKota administrator. No read access to pykotadmin.conf is
647          necessary anymore. This CGI scripts now honors the REMOTE_USER
648          environment variable just like printquota.cgi does, see
649          the file cgi-bin/README for details.
650          The command line tool dumpykota must still be run by a PyKota
651          administrator.
652         
653        - Fix exception's name error due to a change in recent versions
654          of PygreSQL.

658        - Big bug fix wrt the datelimit field which was never reset.
659         
660    - 1.21alpha19 :
661   
662        - Introduction of the new dumpykota.cgi CGI script, which
663          allows third party tools like phpPrintAnalyzer to be
664          interfaced in real time with PyKota. To use it you
665          may have to change your web server's configuration,
666          please see pykota/cgi-bin/README
667         
668    - 1.21alpha18 :
669   
670        - Now dumpykota can dump the job history into CUPS' page_log
671          format (even when the printing system is LPRng). This allows
672          people to use tools like PrintAnalyzer or phpPrintAnalyzer
673          (two completely different beasts) with PyKota.
674         
675    - 1.21alpha17 :
676     
677        - Fixed field type's name in XML dumps.

694        - dumpykota filtering capabilities are now supported within
695          the LDAP backend too.
696         
697    - 1.21alpha14 :
698   
699        - dumpykota now supports extended filtering possibilities
700          with the PostgreSQL backend (LDAP support will come soon).
701         
702    - 1.21alpha13 :
703   
704        - Added a --debug command line option to pkpgcounter, so
705          that people may see what really happens, and what will
706          be available in the future :-)
707         
708    - 1.21alpha12 :
709   
710        - Fixed a bug with non standard pkbanner command lines.

716   
717        - Now user and group print quota entries can be stored directly
718          below the user or group with the LDAP backend, using them
719          as branches. Thanks to Stefan Wold for the patch.
720          See the sample configuration file for details.
721         
722        - TLS is now supported with the LDAP backend. Thanks to Stefan
723          Wold for the patch.
724          See the sample configuration file for details.
725         
726        - edpkota now accepts the -U | --used value command line argument
727          to preset the page counters to an initial value. Thanks to
728          Wilson Roberto Afonso and Matt Hyclak for the patch.
729         
730    - 1.21alpha10 :
731   
732        - Now automatically reconnects up to three times if the LDAP server
733          returned an error, possibly due to a timeout.
734         
735    - 1.21alpha9 :
736   
737        - Now searches the configuration files in 'pykota' system user's
738          home directory. The 'pykota' system user and group have
739          to be created by the system administrator, and given
740          sufficient permissions to PyKota's configuration files.
741

785    - 1.21alpha1 :
786   
787        - added an IPP messages miniparser. Extraction of the client

791    - 1.20 :
792   
793        - Version number changed.

808       
809    - 1.20alpha27 :
810

812          the Brazilian Portuguese translation file was incorrectly
813          installed into the french "breton" locale directory.
814

865        - Now any PyKota administrator can use repykota and warnpykota
866          with additionnal arguments, not only the root user.
867

912         
913    - 1.20alpha15 :
914   
915        - LDAP pykotaAccountBalance objects were always created
916          attached to the pykotaUser objects. This is now
917          fixed and the value of balancebase in pykota.conf
918          is now correctly used.
919         
920    - 1.20alpha14 :
921

936          for this to work (tested with v3.4.2)
937         
938        - Increased delay between two loops iterations 
939          to 2 seconds in waitprinter.sh to diminish
940          CPU load.
941         
942    - 1.20alpha12 :

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

1456       
1457    - 1.18alpha13 :
1458   
1459        - Pre and Post hooks are now available in the pykota
1460          filter as well.
1461         
1462        - The pykota filter doesn't check last user's quota
1463          anymore when delayed hardware accounting is used :
1464          this will be done anyway the next time the last
1465          user will print again. This saves some database
1466          queries which are unneeded.
1467       
1468    - 1.18alpha12 :
1469   
1470        - Pre and Post hooks to external commands with many
1471          many environment variables available are useable
1472          from the cupspykota backend.
1473          See sample configuration file for details and help.
1474         
1475    - 1.18alpha11 :

1488       
1489        - Fix for empty user groups with LDAP.
1490       
1491        - Preliminary version of the snmpprinterstatus command added.
1492       
1493    - 1.18alpha8 :
1494   
1495        - Don't retrieve data when not needed.
1496          This avoids many database queries.
1497       
1498    - 1.18alpha7 :
1499   
1500        - New experimental ldapcache directive to improve
1501          LDAP caching.

1514          Peter Hawkins are now included in the project's tree.
1515         
1516        - Preliminary work on future low-level LDAP caching to speed
1517          up modifications (at least).
1518         
1519    - 1.18alpha4 :
1520   
1521        - Applied some of the modifications suggested by
1522          Peter Hawkins, for better Debian integration.
1523          Most notably cupspykota, pykota, and the shell
1524          scripts are now installed into /usr/share/pykota
1525          instead of into /usr/bin
1526          BEWARE : double check that your symbolic link
1527          to cupspykota is correct, and that your pykota.conf
1528          file use correct path for the shell scripts like
1529          waitprinter.sh and al.
1530         
1531        - pkhint command added, to help in configuring correct
1532          accounting method for PyKota.

1568          added to the documentation. Doesn't yet document v1.16
1569          though.
1570       
1571        - Portuguese Portuguese translation replaces Brazilian
1572          Portuguese Translation. Brazilian portuguese
1573          translation is still available under the 'br' locale.
1574       
1575    - 1.16beta3 :
1576

1581    - 1.16beta2 :
1582   
1583        - Small fix for job cancelling code while job already
1584          printing in CUPS backend.
1585         
1586        - Big fix wrt printing policies for unknown users. 
1587       
1588    - 1.16beta1 :
1589   
1590        - Manpages upgraded.
1591       
1592    - 1.16alpha26 :
1593   
1594        - Job price is now computed like this :
1595       
1596          SUM((NbPages * PricePerPage) + PricePerJob)
1597         
1598          For current printer and all the printers groups it is
1599          a member of, if any.
1600         
1601          This may be difficult to grasp, but offers unprecedented
1602          flexibility.
1603         
1604    - 1.16alpha25 :
1605

1618          automatically add printers on first print.
1619       
1620    - 1.16alpha23 :
1621   
1622        - Fixed potential accuracy problem if a user printed on
1623          several printers at the very same time.
1624

1642       
1643    - 1.16alpha18 :
1644   
1645        - Initial code for printer groups support. Printer groups have
1646          to be added with external tools like psql or gq for example.
1647          Printer groups seems to work fine with users. Untested with user
1648          groups for now.
1649
1650        - Several minor visual problems fixed in reports.
1651       
1652        - Fixed a bug in LDAP date handling.
1653

1658          for details.
1659       
1660        - Several environment variables are now exported when executing
1661          external commands (accounters, requesters, mailers) :
1662           
1663            PYKOTAUSERNAME => user who is printing
1664            PYKOTAPRINTERNAME => printer on which the job is being sent
1665            PYKOTATITLE => Job's title
1666            PYKOTAFILENAME => Job's filename
1667            PYKOTACOPIES => number of copies asked
1668            PYKOTAOPTIONS => print command options (-o with CUPS)
1669         
1670    - 1.16alpha17 :
1671   
1672        - Added portugues translation.
1673       
1674        - Major code refactoring in accounters.
1675

1677   
1678        - Code refactoring, and addition of a real HTML reporter, to
1679          have nice looking and useful web based reports (in the future).
1680       
1681        - Added utolower configuration option to convert all usernames
1682          to lowercase during printing.
1683         
1684    - 1.15alpha15 :
1685   
1686        - Now includes the papwaitprinter.sh shell script to wait for
1687          AppleTalk enabled printers.
1688         
1689    - 1.16alpha14 :
1690   
1691        - Now printing on a printer not defined in the Quota Storage,
1692          results in the job being cancelled or stopped, depending
1693          on the printing system.
1694         
1695    - 1.16alpha13 :
1696   
1697        - Small bugfix wrt Python v2.1
1698       
1699        - If username is an empty string, user root is assumed.
1700       
1701        - 'postgresql' is not recognized anymore as a storage backend,
1702          you have to use 'pgstorage' instead. 'postgresql' used to
1703          be supported for compatibility with very old PyKota versions,
1704          this is not the case anymore.
1705         
1706    - 1.16alpha12 :
1707   
1708        - Job price added to job history, to keep accounting correct
1709          if a printer price per page or per job is modified and the
1710          history is not reset : the history would have given a false
1711          amount of money charged before the printer's prices were
1712          modified, this addition solves the problem.
1713         
1714    - 1.16alpha11 :
1715   
1716        - Some preliminary modifications to the database structure for
1717          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1718          database is now provided. LDAP attributes now support
1719          eq, pres and sub indexes.
1720         
1721        - Job history now contains additional informations : 
1722          number of copies, filename, title and print options.
1723         
1724    - 1.16alpha10 :
1725       
1726        - Some modifications done to external policy handling.
1727          See sample configuration file for details.
1728   
1729        - Spanish translation added.
1730       
1731    - 1.16alpha9 :
1732   
1733        - mailto can be set to external(...) to warn users above
1734          quota with any command of your choice (e.g. linpopup).
1735          Several parameters are available, see sample configuration
1736          file for details.
1737         
1738    - 1.16alpha8 :
1739   
1740        - Now cupspykota transmits SIGTERMS to the original 
1741          backend when the user deletes a job being processed.
1742         
1743        - The documentation is now licensed under the terms of the
1744          GNU GPL too.
1745         
1746    - 1.16alpha7 :
1747   
1748        - The CUPS backend is now fully functionnal (it seems).
1749       
1750        - From now on, the use of the pykota filter with CUPS
1751          is deprecated. The pykota filter still has to be
1752          used with LPRng though.
1753       
1754    - 1.16alpha6 :
1755   
1756        - Bug fixed : when edpykota was used to add a printer
1757          with no user or group name, a bad user/group name "*" was
1758          added to the database.
1759         
1760    - 1.16alpha5 :
1761   
1762        - New CUPS backend supports device enumeration !
1763          This means that NO manual CUPS configuration has to
1764          be done. All can now be done from CUPS web interface.
1765       
1766    - 1.16alpha4 :
1767   
1768        - New CUPS backend added.
1769       
1770    - 1.16alpha3 :
1771       
1772        - Minimal FAQ document added.

1781       
1782        - More complete error messages in case of LDAP operation failure.
1783       
1784    - 1.15 :
1785     
1786        - Documentation improved.
1787       
1788    - 1.15beta :
1789   
1790        - Command line tools now accept multiple printer
1791          names or wildcards, separated with commas.
1792         
1793    - 1.15alpha9 :
1794   
1795        - External policy can be used to auto-add unknown users
1796          and any other interesting things you may want to do.
1797          WARNING : You can't auto-add printers for now.
1798          They have to be created manually before.
1799          Look at sample configuration file for examples.
1800         
1801    - 1.15alpha8 :
1802   
1803        - Job history can be disabled if needed.
1804          This feature may be useful for people who use the LDAP
1805          backend and don't want their LDAP tree to grow out of
1806          control.
1807       
1808    - 1.15alpha7 :
1809   
1810        - More work done on caching wrt groups.

1818        - Caching mechanism for all database queries.
1819
1820    - 1.15alpha4 :
1821   
1822        - Problem with Python 2.3 fixed. Needs some definitive
1823          modification.
1824         
1825    - 1.15alpha3 :
1826   
1827        - CGI script now tries to restrict view when the
1828          REMOTE_USER environment variable is set. This allows
1829          people to protect its use with .htaccess files.
1830          When unprotected, or if REMOTE_USER is 'root', then
1831          unrestricted access is granted.
1832          NB : REMOTE_USER is automatically set by the web server
1833          (e.g. Apache) when a page with restricted access is viewed.
1834         
1835    - 1.15alpha2 :
1836   
1837        - Better detection of LPRng.
1838       
1839        - Outputs a warning if printing system is unknown.
1840       
1841    - 1.15alpha1 :
1842   
1843        - Bug fix in SQL code.
1844       
1845    - 1.14 :
1846   
1847        - The PostgreSQL database connection is now always closed before
1848          exit. The LDAP database connection too, but it didn't suffer
1849          from the problem anyway, AFAICT.
1850       
1851    - 1.14beta2 :
1852   
1853        - An LDAP-specific configuration field was introduced, usermail.
1854          Use it to specify which LDAP attribute contains a valid email
1855          address for the user. See sample configuration file for
1856          details.
1857       
1858    - 1.14beta :
1859   
1860        - Two new LDAP-specific configuration fields were introduced,
1861          newuser and newgroup. Use them to specify if you want to add
1862          quota information to existing entries or elsewhere.
1863          See sample configuration file for details.
1864         
1865    - 1.14alpha9 :
1866   
1867        - Documentation improved.
1868       
1869        - pykotme now also prints the user's account balance value
1870          if the user is registered in the Quota Storage and his
1871          limiting factor is "balance".
1872         
1873    - 1.14alpha8 :
1874   
1875        - bin/waitprinter.sh is now included to wait for
1876          SNMP enabled printers to be idle again before
1877          asking for their internal page counter.
1878          See sample configuration file for details.
1879         
1880    - 1.14alpha7 :
1881   
1882        - edpykota now doesn't check if the user/group is above
1883          quota. The check is only done at print time. This
1884          prevents the sending of email messages when creating
1885          user quotas if quota is already reached at creation
1886          time.
1887         
1888    - 1.14alpha6 :
1889   
1890        - Configuration file split and moved to /etc/pykota/pykota.conf
1891          and /etc/pykota/pykotadmin.conf to prevent simple users to
1892          have Read/Write access to the Quota Database.
1893          Don't forget to :
1894         
1895                $ chmod 640 /etc/pykota/pykotadmin.conf
1896               
1897        - storageuser and storageuserpw configuration fields reintroduced
1898          for the same reason.
1899         
1900        - Code cleaning for future implementation of email addresses
1901          support in the PostgreSQL and LDAP backends.
1902         
1903    - 1.14alpha5 :
1904       
1905        - Big bug fixed when changing the prices for a printer
1906       
1907    - 1.14alpha4 :
1908   
1909        - When adding an user, the user itself and its account balance
1910          are now added in the same LDAP entry. Before they were added
1911          as two different LDAP entries.
1912         
1913    - 1.14alpha3 :
1914   
1915        - Email field added to PostgreSQL database. An upgrade script
1916          is included in initscripts/postgresql.

1923   
1924        - Poor man's treshold included : users with a low account
1925          balance (below 1.0 by default, configurable) are sent
1926          a warning message.
1927         
1928        - All warning messages to users are now configurable. 
1929          NB : Warning messages to the administrator are not.
1930       
1931    - 1.13 :
1932   
1933        - Some small fixes wrt group handling.
1934       
1935        - The whole module code was passed through PyChecker and
1936          several small code inconsistencies were fixed,
1937          as well as a bug in the groups code.
1938         
1939    - 1.13alpha1 :
1940

1996   
1997    - 1.09alpha1 :
1998   
1999        - More work on LDAP storage backend. Many options
2000          were added to /etc/pykota.conf to give some

2019          not used anymore.
2020         
2021        - You can now set PyKota in debug mode, see sample configuration 
2022          file for details.
2023          WARNING : only Quota Storage backend queries are logged in
2024          debug mode, for now.
2025       
2026    - 1.08alpha7 :
2027   
2028        - Very latest LDAP schema.
2029       
2030        - Code enhancement wrt easy pluggability of PyKota attributes

2042          repykota now works reasonably well with the sample LDAP directory.
2043       
2044    - 1.08alpha4 :
2045   
2046        - LDAP schema included.
2047          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2048          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2049          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2050          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2051          MAILING LIST.
2052         
2053    - 1.08alpha3 :
2054   
2055        - External accounting methods were partly rewritten :
2056         
2057          - No more "broken pipe" should happen.
2058         
2059          - They now take care of the number of copies
2060            This may be unneeded though, if the postscript
2061            file already does this, because this would
2062            overcharge users (number of copies counted
2063            two times). NEEDS MORE TESTING.
2064           
2065          - The sample configuration file now contains 
2066            an external accounting method example which should
2067            work with all DSC compliant Postscript files.
2068           
2069        - Some small bugs were fixed.   
2070       
2071    - 1.08alpha2 :
2072   
2073        - Now works with net-snmp v5.0 and above.
2074          It already worked, but the sample configuration
2075          file didn't contain appropriate values...
2076       
2077    - 1.07 : Release of the Shame !
2078   
2079        - The external accounting methods driver was left out of
2080          the CVS tree. Nobody could use it since it wasn't included !
2081         
2082    - 1.06 :
2083   
2084        - Severe bug fixed : if you had a printer in
2085          power saving state which couldn't answer immediately,
2086          a bug was triggered.
2087          It was caused by a bad copy/paste which
2088          forgot to import a Python module at run time.
2089         
2090    - 1.05 :
2091   
2092        - External accounters are finally available !
2093          This means that you can plug any page accounting
2094          method you like by setting the appropriate
2095          'accounter' field in /etc/pykota.conf
2096          See the sample conf/pykota.conf.sample to
2097          learn how to do.
2098         
2099          NB : Both 'external' and 'stupid' accounting methods
2100               account a job size just before *this* job is
2101               sent to the printer.
2102               The original 'querying' method accounts a job
2103               size just before *the next* job is sent to
2104               the printer.
2105       
2106    - 1.05alpha3 :
2107   
2108        - A 'stupid' and unreliable accounting method was
2109          implemented to serve as an example on how to
2110          do this sort of things. This method only counts
2111          the 'showpage' statements in the input data.
2112          See sample configuration file for details.
2113          Pluggable accounting methods work, but I advise
2114          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2115          It is not reliable enough to be used.
2116          Use the 'querying' accounting method instead.
2117         
2118    - 1.05alpha2 :
2119   
2120        - Pluggable accounting methods.
2121       
2122        - Better error handling.
2123       
2124    - 1.05alpha1 :
2125   
2126        - SECURITY file added to help improve PyKota's security.
2127       
2128        - Extracting the printer's internal page counter is now
2129          tried several times, waiting several seconds between
2130          two tries. This lets the time to warm up for some printers
2131          which don't answer when they are sleeping (my Apple
2132          LaserWriter 16/600 PS is in this case, maybe others too)
2133         
2134        - Small display bug fixed in repykota
2135         
2136    - 1.04 :
2137   
2138        - Default print policy for users/groups unknown from
2139          the print quota system is now DENY instead of ALLOW,
2140          since ALLOW can generate inaccurate results
2141          (incorrect job sizes charged to the wrong persons)
2142         
2143        - LPRng support works !
2144       
2145        - A bug was introduced some time ago wrt printers' default
2146          policy for unknown users. It is now corrected.
2147       
2148        - repykota now displays prices per job and per page for each
2149          printer, if they are defined.
2150         
2151        - Minor display bug fixed in repykota.
2152       
2153        - Problem when running repykota with an empty database was fixed.
2154       
2155    - 1.03 :
2156   
2157        - Upgrade script included for earlier versions.
2158          Please look inside the initscripts subdirectory.
2159          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2160         
2161        - repykota now reports account balances too.
2162       
2163        - PyKota now has a nice logo, see the logos
2164          subdirectory.
2165       
2166        - Manual pages were finally updated.
2167       
2168        - Group quotas seem to work now !
2169       
2170        - The new database schema allows to keep an history of all
2171          jobs as well as charge users per page and/or per job,
2172          and track users' account balance.
2173         
2174        - edpykota now accepts much more command line options to 
2175          use the new functionnalities. See edpykota --help for
2176          details.
2177         
2178        - The installation script now allows to install the sample
2179          configuration file during first installation.
2180         
2181        - More group quota code works, but still not finished. 
2182       
2183        - The CGI script displays a link to PyKota's website.
2184       
2185        - The job history is now kept, this will allow per-period
2186          reports in the future.
2187         
2188        - After having modified the quota for an user with edpykota,
2189          a quota check is done to eventually warn the user/admin about
2190          a quota which is too low to print.
2191         
2192        - A workaround is provided for HP Printers : their internal
2193          page counter is only saved to NVRAM in a 10 increment, so
2194          if you switch them off and then on, the reported page counter
2195          may be lower than the real number of pages printed.
2196          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2197          We unconditionnally set the last job's page count to
2198          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2199          in this case.
2200          For a more accurate accounting, never switch your HP printers
2201          off.
2202         
2203        - A fix is provided for printers which only have a volatile 
2204          page counter (reset to 0 every time you switch the printer on)
2205          This should allow PyKota to work reasonably fine with HP Laserjet
2206          4L/5L/6L, not perfect, but better than nothing.
2207          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2208          For a more accurate accounting, never switch your HP printers
2209          off. This is untested, please report any problem.
2210         
2211        - A bug was fixed when edpykota --add was used with users who already
2212          had a quota on the specified printer.
2213         
2214        - A small display bug in repykota was introduced in preliminary
2215          1.03 versions, and fixed later on.
2216         
2217        - Some minor bugs which happened in rare situations were fixed.
2218       
2219        - Support for AppleTalk printers was added, see sample configuration
2220          file for details.
2221         
2222        - Users and group printing can now be controlled (limited) either by 
2223          print quota or by account balance.
2224       
2225    - 1.02 :
2226   
2227        - The installation script now checks for software availability
2228          and in case a software is missing asks the user if he
2229          wants to continue with the installation or abort it.
2230         
2231        - The configuration file pykota.conf is now expected to be
2232          found in /etc instead of in /etc/cups
2233          The installation script prompts the user to see if he
2234          wants to move an old configuration file to the new location
2235          if needed.
2236         
2237        - Improved documentation.
2238       
2239        - You can now set the tcp/ip port on which the Quota Storage
2240          Server is listening, see sample configuration file for details.
2241       
2242        - Better general error handling.
2243       
2244        - Upgrade script for pre 1.01 PostgreSQL database schema is now
2245          included as well.
2246       
2247    - 1.01 :
2248   
2249        - The configuration file now accepts an option   
2250          to choose the recipient(s) of the email messages :
2251         
2252            - DevNull means no one will receive them.
2253            - User means only the user will receive them.
2254            - Admin means only the admin will receive them.
2255            - Both means the User and the Admin will receive them.
2256           
2257        - The configuration file now uses hard-coded default values
2258          when an option is not set. See sample configuration file
2259          for details.
2260         
2261        - Manual pages are included since 1.00, but I forgot to   
2262          add this information to this file.
2263         
2264        - Redistribution terms for the official package have 
2265          softened and are now fully GPL compatible :
2266          unrestricted modification is now allowed even for
2267          the version number.
2268         
2269    - 1.00 :
2270   
2271        - edpykota now accepts a --noquota option. This
2272          disable quota checking while still doing page
2273          accounting. This is really useful for people
2274          who don't want to limit their users but want
2275          to know how much pages they print.
2276         
2277        - Some untested scripts were added to retrieve
2278          the life time page counter of non-SNMP printers.
2279         
2280        - Every directory now has a specific README file. 
2281       
2282    - 0.99 :
2283   
2284        - Under some circumstances while the user wasn't allowed
2285          to print, he didn't receive any email message. It is
2286          now fixed.
2287         
2288        - When an user wasn't allowed to print, the quota for
2289          the previous user wasn't updated. This is now fixed.
2290         
2291    - 0.98 :
2292   
2293        - Correctly handle the case where the printer is switched off.
2294       
2295        - Small bug wrt syslog fixed.
2296       
2297    - 0.97 :
2298   
2299        - edpykota accepts wildcards on its command line for users/groups too
2300          if the --add option is not set, e.g. :
2301         
2302              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
2303             
2304        - If no user name is passed at all, then a default wildcard of "*"
2305          which means apply the command on ALL users for this printer is used.
2306         
2307        - Small bug fixes.
2308       
2309    - 0.96 :
2310
2311        - Options requester, policy, admin, adminmail and gracedelay can now
2312          be set either globally or per printer. The printer option has
2313          priority if both are defined.
2314
2315        - More powerful configuration parser.
2316       
2317        - If all options are defined globally, there's no need to
2318          define a section for each printer in the configuration
2319          file anymore. Just define a [global] section and it's ok.
2320
2321    - 0.95 :
2322
2323        - External requesters for printers finally added.
2324
2325        - Full internationalization (english and french are supported)
2326 
2327        - More complete quota usage report
2328
2329        - CGI script to access to the quota usage report
2330
2331        - Several bugs fixed.
2332
2333
2334    - 0.9 :
2335
2336        - First public version
