22PyKota NEWS :
23       
24    - 1.25alpha7 (2006-06-20) :
25   
26        - Fixed some date formatting problems when retrieving the
27          printing history with MySQL.
28         
29        - Began code cleaning. 
30         
31    - 1.25alpha6 (2006-06-13) :
32   
33        - pkusers now supports the --email command line switch.
34          The old method to set the email address is still supported,
35          but the new one allows the email address to be modified
36          as well.
37         
38    - 1.25alpha6 (2006-06-09) :
39   
40        - Fixed the incorrect overwriting of the original billing
41          code if the overwrite_jobticket directive was used.
42         
43    - 1.25alpha5 (2006-06-03) :
44   
45        - Fixed minor issues with pkipplib's usage.
46       
47        - Fixed MySQL schema to workaround some "features"...
48       
49    - 1.25alpha4 (2006-05-23) :
50   
51        - Introduced the 'askconfirmation' directive to interact with
52          the end user through any script (pknotify is recommended)
53          and see if he really wants to print when knowing the cost
54          of the job.
55         
56        - Now uses pkipplib if present to directly retrieve the job
57          information from the CUPS server over IPP.
58         
59    - 1.25alpha3 (2006-05-11) :
60   
61        - Added a lock to ensure that a single cupspykota backend
62          is processing datas for a particular print queue at any
63          given time.
64         
65        - Now exports more environment variables for the subprocesses.
66         
67    - 1.25alpha2 (2006-05-03) :
68   
69        - Fixed some problems with DateTime objects.
70

72       
73    - 1.25alpha1 (2006-04-14) :
74   
75        - Make the MySQL schema work with old releases of MySQL.
76       
77        - Fixed several character encoding problems.
78         
79        - Ensures that the denied banners counter is properly initialized
80          with relationnal databases.
81         
82    - 1.24 (2006-04-08) :
83   
84        - Improved documentation and packaging stuff.
85       
86    - 1.24beta (2006-03-26) :
87   
88        - Finalized the pknotify command.
89       
90        - Updated the messages catalogs for translations.
91       
92    - 1.24alpha18 (2006-03-15) :
93   
94        - Now uses MIME encapsulation for email messages to avoid
95          some problems with 8 bits messages being rejected.
96         
97    - 1.24alpha17 (2006-03-06) :
98   
99        - Fixed a major problem in the PostgreSQL backend.
100       
101        - pknotify can now check a remote user's name and password.
102       
103    - 1.24alpha16 (2006-03-02) :
104   
105        - Introduced the pknotify command line tool to dialog
106          with remote PyKotIcon applications.
107         
108    - 1.24alpha15 (2006-03-02) :
109       
110        - optimized pkbcodes, pkprinters and pkusers using edpykota as
111          the model.
112       
113        - 'edpykota --list' and 'pkusers --list' are now authorized
114          to mere mortal users, but the list is restricted to informations
115          about the current user.
116       
117        - Extended the functionnality of the 'onbackenderror' directive to
118          allow for configurable retries.
119         
120    - 1.24alpha14 :
121   
122        - Finished optimizations in edpykota and fixed some minor
123          problems with LDAP.
124         
125    - 1.24alpha13 :
126   
127        - Introduced the pkusers command line tool to manage users and 
128          users groups. This command doesn't deal with print quota entries,
129          which continue to be managed through the edpykota command line
130          tool.
131         
132        - Major rewrite and incompatible changes to command line options
133          in edpykota. This command now only deals with print quota
134          entries. Printers, users (or users groups) now have to be created
135          first using pkprinters or pkusers.
136         
137    - 1.24alpha12 :
138   
139        - Introduced the 'duplicatesdelay' directive to specify after
140          which duration two duplicate jobs are not considered duplicate
141          jobs anymore.
142         
143        - Introduced the 'balancezero' directive to specify any value 
144          as the balance limit instead of 0.0. This can allow admins to
145          give a few free credits to users, for example.
146         
147    - 1.24alpha11 :
148   
149        - Huge speed improvements when modifying billing codes and
150          printers.
151       
152        - Both pkbcodes and pkprinters now display the percent done
153          for all actions.
154         
155        - The pkinvoice invoice generator command line utility is now
156          included.
157         
158    - 1.24alpha10 :   
159   
160        - Huge speed improvements when deleting users, printers, and
161          billing codes.
162         
163    - 1.24alpha9 :
164   
165        - Preliminary support for MySQL, thanks to Matt Hyclak.
166       
167    - 1.24alpha8 :
168   
169        - The 'preaccounter' configuration directive was introduced to control
170          which parser to use for precomputation of the job's size. When unset,
171          the internal parser is used just like it was previously. See
172          conf/pykota.conf.sample for more details.
173         
174        - Now subprocesses launched through the overwrite_jobticket directive
175          can also output 'CANCEL', to represent the user's own choice to
176          cancel the print job.
177         
178    - 1.24alpha7 :
179     
180        - pkbanner now handles new print limiting modes correctly.
181       
182        - The cupspykota backend wrapper now accepts to be interrupted
183          with a kill -INT. This causes an immediate and clean abort
184          of the current print job.
185         
186        - Matt Hyclak contributed the possibility to store the printing
187          history in a MySQL database. See the contributed/ directory
188          for details.
189         
190        - Added 2006 to the copyright's years.
191       
192    - 1.24alpha6 :
193   
194        - Fixed internal SNMP and PJL handling code for very fast
195          printers : PyKota didn't see them going from 'idle'
196          to 'printing' to 'idle' again.
197         
198        - Now waitprinter.sh accepts SNMP version number and
199          community name as arguments, thanks to Brandon
200          Holbrook.
201         
202        - Now command line errors and Ctrl+C repectively cause
203          PyKota commands to exit with status -2 and -3.
204         
205    - 1.24alpha5 :
206   
207        - All command line tools now accept -A | --arguments filename.args
208          as a way to bypass the shell's maximal command line size :
209          just put each argument on a line by itself in a file, and
210          pass the file's name as the -A | --arguments command line
211          option's argument. For now this won't be documented in
212          commands' helps.
213         
214        - dumpykota can now dump the complete database in XML
215          format.
216         
217    - 1.24alpha4 :
218   
219        - Added support for the SQLite3 backend.
220          See pykota/initscripts/sqlite/README.sqlite
221       
222    - 1.24alpha3 :
223   
224        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
225          so we regain priviledges before running an external
226          mailto directive.
227       
228    - 1.24alpha2 :
229   
230        - Introduce the "onbackenderror" directive in pykota.conf, to
231          control if the user must be charged or not whenever a real
232          CUPS backend fails. The default value is 'nocharge'.
233          Set it to 'charge' if you think your users can cause a CUPS
234          backend to fail.
235         
236        - Now mark original backends related problems as such in the
237          printing history. Modified printquota.cgi and pykota.css
238          to make them be more visible.
239         
240    - 1.24alpha1 :
241   
242        - Fixed a problem which caused backend errors to be ignored.
243       
244        - The sample LDIF file now contains the two necessary user
245          entries to have an LDAP PyKota Admin and an LDAP PyKota
246          ReadOnly user. The sample configuration files were updated
247          to contain the default passwords used in the LDIF file.
248         
249        - dumpykota is now more strict when checking arguments.   
250       
251    - 1.23 :
252   
253        - Many minor bug fixes and code cleaning.
254       
255        - Improved documentation.
256       
257        - Added Polish translation.
258       
259        - Improved French and Swedish translations.
260       
261    - 1.23beta :
262   
263        - Now the mailto directive is honored in all cases where the job is
264          denied or a warning has to be issued, and the correct reason
265          can be sent back to the user.
266         
267        - The PYKOTAREASON environment variable, if defined, contains the 
268          textual reason why the job was denied or a warning has to be
269          issued.
270       
271    - 1.23alpha31 :
272   
273        - Added support for --maxjobsize, --passthrough and --nopassthrough
274          in pkprinters. These modes are now also honored when printing.
275         
276        - Allows the admin to restrict the number of print queues which will
277          be treated by pkturnkey by passing queues' names as additionnal
278          arguments on pkturnkey's command line.
279         
280        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
281          command line option.   
282         
283    - 1.23alpha30 :
284   
285        - Database changes : you MUST use upgrade-to-1.23.sql again if you
286          use PostgreSQL, or copy the new schema and restart your LDAP
287          server if you use LDAP.
288         
289        - The -C | --comment command line switch was added to edpykota to 
290          attach textual information to modifications done to a user's
291          account balance.
292         
293        - The -l | --limitby command line switch to edpykota was modified 
294          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
295          command's help or manual page for details.
296         
297        - The -i | --ingroups command line switch to repykota allows 
298          PyKota Administrators to only lists members of the specified
299          group or groups (separated with commas).
300         
301        - The -I | --increase command line switch to edpykota allows
302          to increase or decrease page limits.
303         
304        - Added the precomputed job's size and price to the history
305          for controlling purpose.
306       
307    - 1.23alpha29 :
308   
309        - Fixed a small problem with billing codes.
310       
311        - Exports some environment variables earlier, to render the script
312          launched by the overwrite_jobticket directive more powerful.
313         
314        - Now autopykota also creates print quota entries for the user on the
315          printers groups the current printer is a member of.
316         
317    - 1.23alpha28 :
318   
319        - Added users groups management to pkturnkey.
320       
321        - Fixed umask in setup script.
322       
323    - 1.23alpha27 :
324   
325        - Replaced the --dryrun command line option by the --force
326          command line option in pkturnkey, with exactly the opposite
327          effect (for security reasons).
328         
329    - 1.23alpha26 :
330   
331        - Allows parametrized pjl and snmp hardware accounting methods,
332          to be able to respectively set the TCP port and the SNMP
333          community.
334         
335    - 1.23alpha25 :
336   
337        - Added a --dryrun command line switch to pkturnkey.
338       
339        - Improved pkturnkey's general usability.
340       
341        - Added a manpage for pkturnkey.
342       
343    - 1.23alpha24 :
344   
345        - Allows different databases to be used depending on the
346          user's rights. This allows PyKota admins to directly
347          use a master LDAP server for read+write, while letting
348          normal users using the replicas for readonly access.
349          NB : using different storage backends is also possible,
350          but you're on your own there.
351         
352    - 1.23alpha23 :
353   
354        - Fixed a problem with banner accounting.
355   
356        - Introduction of the new 'pkturnkey' command line tool.
357       
358    - 1.23alpha22 :
359   
360        - The cupspykota backend was almost entirely rewritten from scratch.
361          It's now much more readable, maintainable, etc...
362         
363        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
364          advised to download earlier releases or purchase the
365          PyKota v1.22HotFix1 Official release. LPRng support
366          MIGHT be re-added later.
367       
368    - 1.23alpha21 :
369     
370        - Fix for IPP requests which contain more than a single
371          job-originating-host-name attribute.
372         
373    - 1.23alpha20 :
374   
375        - Added the overwrite_jobticket directive. See pykota.conf.sample
376          for how to use it.
377         
378    - 1.23alpha19 :
379   
380        - Fixed an LDAP filtering problem when managing billing codes.
381       
382        - Added the unknown_billingcode directive. See pykota.conf.sample
383          for how to use it.
384       
385    - 1.23alpha18 :
386     
387        - Added the dump_bfd.php contribution.
388       
389        - Several fixes in the internal PJL accounter.
390       
391        - Now autopykota doesn't create unneeded print quota entries anymore.
392       
393        - Increased the timeout in the PJL hardware accounting code to
394          accomodate some printers (HP5000 at least).
395         
396    - 1.23alpha17 :
397   
398        - pkpgcounter is now distributed separately only. This
399          means that people must now download and install pkpgcounter
400          v1.56 or higher prior to being able to run PyKota.
401         
402        - Removed all the autoconf/automake stuff which was outdated 
403          and confusing.
404         
405    - 1.23alpha16 :
406     
407        - Extracted the GPL blurb from all commands' help, and use
408          a static version only once. This saves space big time, and
409          eases future translations.
410         
411    - 1.23alpha15 :
412   
413        - pkbcodes now works with the PostgreSQL backend.
414          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
415       
416    - 1.23alpha14 :
417   
418        - Logs a warning when the user/group doesn't exist when running
419          edpykota.
420         
421    - 1.23alpha13 :
422   
423        - Minor fix for user groups because of latest database changes.
424       
425    - 1.23alpha12 :
426   
427        - Big database changes, use the migration scripts !
428       
429    - 1.23alpha11 :
430   
431        - Small fix to the PCL3/4/5 parser for some drivers.
432       
433    - 1.23alpha10 :
434   
435        - Fixed a bad exception name in cupspykota when parsing IPP messages.
436       
437        - Improved the IPP messages module : it can now generate IPP messages
438          in addition to parsing them.
439       
440    - 1.23alpha9 :   
441   
442        - The denyduplicates directive now accepts a command line as an
443          argument beside yes/no. The command is launched and must
444          print either ALLOW or DENY to its standard output. Then the
445          job gets allowed or denied by PyKota.
446          This will allow user interaction in the near future.
447         
448        - Introduced the new 'striptitle' directive to remove ugly prefixes
449          from print job's titles whenever a new print job is submitted.
450         
451        - Fixed internal SNMP accounter for printers which only have a life time
452          page counter, and not a volatile page counter.
453         
454    - 1.23alpha8 :
455   
456        - The data dumper can now summarize payments and history with the
457          help of the --sum command line option (or checkbox in the CGI).
458         
459        - The message used when the job's filename, title and options are
460          hidden because of the privacy directive is now translated at
461          retrieval time, instead of at saving time.
462         
463        - Minor fix in the LDAP backend code. 
464         
465    - 1.23alpha7 :
466   
467        - Improvements to the internal PJL and SNMP accounter : now should
468          support more printers and waste less time.
469         
470    - 1.23alpha6 :
471   
472        - The data dumper's start= and end= date filtering options now
473          accept a positive or negative offset to be added to the special
474          keywords 'yesterday', 'today', 'now', 'tomorrow'.
475          e.g. : dumpykota --data history start=yesterday-5 end=today
476         
477    - 1.23alpha5 :
478   
479        - The data dumper's start= and end= date filtering options now accept
480          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
481         
482    - 1.23alpha4 :

487    - 1.23alpha3 :
488   
489        - The destination link for the logo used in CGI scripts is

505   
506        - Sets current username to the user CUPS runs as instead of "root"
507          when printing test pages from CUPS' web interface (because

572       
573        - Fixes some problem for printers which directly go from

576         
577        - Some permissions settings may have prevented cupspykota
578          from parsing cupsd.conf, this is now fixed.

615    - 1.21alpha27 :
616   
617        - Allows software() (no arguments) to the software accounting
618          directive. This saves a lot of CPU since the job is not
619          parsed again : the precomputed size is used directly in this
620          case.
621         
622        - epykota's --prototype option now works fine with accounts
623          limited by balance.

637         
638        - Introduction of the new 'trustjobsize' configuration directive
639          to workaround some problematic printers. See the sample
640          configuration file for details.
641         
642    - 1.21alpha24 :
643   
644        - Big database structure changes. An upgrade script
645          is now included for PostgreSQL. LDAP users may just
646          want to copy the new schema in place.
647         
648        - edpykota now recognizes the -o | --overcharge command line
649          option to set an overcharging or undercharging factor
650          on each print job's cost for a particular user.
651         
652        - repykota's output format has changed an is not limited to 
653          80 characters wide anymore. People who used to parse
654          repykota's output in their own tools are strongly advised
655          to parse dumpykota's output instead.
656         
657        - Introduction of the new 'maxdenybanners' configuration directive
658          to allow up to N (the directive's value) deny banners to be
659          printed even if the print account is forbidden to print.
660         
661        - Better detection of the number of copies in the PostScript parser.

668       
669    - 1.21alpha22 :
670   
671        - edpykota's --delete command line option doesn't consider
672          '*' to be the default argument anymore :-)
673         
674    - 1.21alpha21 :
675   
676        - dumpykota.cgi can now be run as a normal user as opposed to
677          a PyKota administrator. No read access to pykotadmin.conf is
678          necessary anymore. This CGI scripts now honors the REMOTE_USER
679          environment variable just like printquota.cgi does, see
680          the file cgi-bin/README for details.
681          The command line tool dumpykota must still be run by a PyKota
682          administrator.
683         
684        - Fix exception's name error due to a change in recent versions
685          of PygreSQL.

689        - Big bug fix wrt the datelimit field which was never reset.
690         
691    - 1.21alpha19 :
692   
693        - Introduction of the new dumpykota.cgi CGI script, which
694          allows third party tools like phpPrintAnalyzer to be
695          interfaced in real time with PyKota. To use it you
696          may have to change your web server's configuration,
697          please see pykota/cgi-bin/README
698         
699    - 1.21alpha18 :
700   
701        - Now dumpykota can dump the job history into CUPS' page_log
702          format (even when the printing system is LPRng). This allows
703          people to use tools like PrintAnalyzer or phpPrintAnalyzer
704          (two completely different beasts) with PyKota.
705         
706    - 1.21alpha17 :
707     
708        - Fixed field type's name in XML dumps.

725        - dumpykota filtering capabilities are now supported within
726          the LDAP backend too.
727         
728    - 1.21alpha14 :
729   
730        - dumpykota now supports extended filtering possibilities
731          with the PostgreSQL backend (LDAP support will come soon).
732         
733    - 1.21alpha13 :
734   
735        - Added a --debug command line option to pkpgcounter, so
736          that people may see what really happens, and what will
737          be available in the future :-)
738         
739    - 1.21alpha12 :
740   
741        - Fixed a bug with non standard pkbanner command lines.

747   
748        - Now user and group print quota entries can be stored directly
749          below the user or group with the LDAP backend, using them
750          as branches. Thanks to Stefan Wold for the patch.
751          See the sample configuration file for details.
752         
753        - TLS is now supported with the LDAP backend. Thanks to Stefan
754          Wold for the patch.
755          See the sample configuration file for details.
756         
757        - edpkota now accepts the -U | --used value command line argument
758          to preset the page counters to an initial value. Thanks to
759          Wilson Roberto Afonso and Matt Hyclak for the patch.
760         
761    - 1.21alpha10 :
762   
763        - Now automatically reconnects up to three times if the LDAP server
764          returned an error, possibly due to a timeout.
765         
766    - 1.21alpha9 :
767   
768        - Now searches the configuration files in 'pykota' system user's
769          home directory. The 'pykota' system user and group have
770          to be created by the system administrator, and given
771          sufficient permissions to PyKota's configuration files.
772

816    - 1.21alpha1 :
817   
818        - added an IPP messages miniparser. Extraction of the client

822    - 1.20 :
823   
824        - Version number changed.

896        - Now any PyKota administrator can use repykota and warnpykota
897          with additionnal arguments, not only the root user.
898

944    - 1.20alpha15 :
945   
946        - LDAP pykotaAccountBalance objects were always created
947          attached to the pykotaUser objects. This is now
948          fixed and the value of balancebase in pykota.conf
949          is now correctly used.
950         
951    - 1.20alpha14 :
952

967          for this to work (tested with v3.4.2)
968         
969        - Increased delay between two loops iterations 
970          to 2 seconds in waitprinter.sh to diminish
971          CPU load.
972         
973    - 1.20alpha12 :

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

1463   
1464        - Small fix for new waitprinter.sh script
1465       
1466        - Better tracebacks on error conditions
1467       
1468        - Improved translations
1469       
1470        - Improved documentation
1471       
1472    - 1.18alpha15 :
1473
1474        - waitprinter.sh replaced by a new and possibly faster
1475          and more powerful one.
1476

1483        - Catches more (all ?) problems with SMTP servers instead
1484          of breaking.
1485         
1486        - Italian translation added.
1487       
1488    - 1.18alpha13 :
1489   
1490        - Pre and Post hooks are now available in the pykota
1491          filter as well.
1492         
1493        - The pykota filter doesn't check last user's quota
1494          anymore when delayed hardware accounting is used :
1495          this will be done anyway the next time the last
1496          user will print again. This saves some database
1497          queries which are unneeded.
1498       
1499    - 1.18alpha12 :
1500   
1501        - Pre and Post hooks to external commands with many
1502          many environment variables available are useable
1503          from the cupspykota backend.
1504          See sample configuration file for details and help.
1505         
1506    - 1.18alpha11 :

1519       
1520        - Fix for empty user groups with LDAP.
1521       
1522        - Preliminary version of the snmpprinterstatus command added.
1523       
1524    - 1.18alpha8 :
1525   
1526        - Don't retrieve data when not needed.
1527          This avoids many database queries.
1528

1530   
1531        - New experimental ldapcache directive to improve
1532          LDAP caching.

1545          Peter Hawkins are now included in the project's tree.
1546         
1547        - Preliminary work on future low-level LDAP caching to speed
1548          up modifications (at least).
1549         
1550    - 1.18alpha4 :
1551   
1552        - Applied some of the modifications suggested by
1553          Peter Hawkins, for better Debian integration.
1554          Most notably cupspykota, pykota, and the shell
1555          scripts are now installed into /usr/share/pykota
1556          instead of into /usr/bin
1557          BEWARE : double check that your symbolic link
1558          to cupspykota is correct, and that your pykota.conf
1559          file use correct path for the shell scripts like
1560          waitprinter.sh and al.
1561         
1562        - pkhint command added, to help in configuring correct
1563          accounting method for PyKota.

1599          added to the documentation. Doesn't yet document v1.16
1600          though.
1601       
1602        - Portuguese Portuguese translation replaces Brazilian
1603          Portuguese Translation. Brazilian portuguese
1604          translation is still available under the 'br' locale.
1605       
1606    - 1.16beta3 :
1607

1611       
1612    - 1.16beta2 :
1613   
1614        - Small fix for job cancelling code while job already
1615          printing in CUPS backend.
1616         
1617        - Big fix wrt printing policies for unknown users. 
1618       
1619    - 1.16beta1 :
1620   
1621        - Manpages upgraded.
1622       
1623    - 1.16alpha26 :
1624   
1625        - Job price is now computed like this :
1626       
1627          SUM((NbPages * PricePerPage) + PricePerJob)
1628         
1629          For current printer and all the printers groups it is
1630          a member of, if any.
1631         
1632          This may be difficult to grasp, but offers unprecedented
1633          flexibility.
1634         
1635    - 1.16alpha25 :
1636

1649          automatically add printers on first print.
1650       
1651    - 1.16alpha23 :
1652   
1653        - Fixed potential accuracy problem if a user printed on
1654          several printers at the very same time.
1655

1673       
1674    - 1.16alpha18 :
1675   
1676        - Initial code for printer groups support. Printer groups have
1677          to be added with external tools like psql or gq for example.
1678          Printer groups seems to work fine with users. Untested with user
1679          groups for now.
1680
1681        - Several minor visual problems fixed in reports.
1682       
1683        - Fixed a bug in LDAP date handling.
1684

1689          for details.
1690       
1691        - Several environment variables are now exported when executing
1692          external commands (accounters, requesters, mailers) :
1693           
1694            PYKOTAUSERNAME => user who is printing
1695            PYKOTAPRINTERNAME => printer on which the job is being sent
1696            PYKOTATITLE => Job's title
1697            PYKOTAFILENAME => Job's filename
1698            PYKOTACOPIES => number of copies asked
1699            PYKOTAOPTIONS => print command options (-o with CUPS)
1700         
1701    - 1.16alpha17 :
1702   
1703        - Added portugues translation.
1704       
1705        - Major code refactoring in accounters.
1706       
1707    - 1.16alpha16 :
1708   
1709        - Code refactoring, and addition of a real HTML reporter, to
1710          have nice looking and useful web based reports (in the future).
1711       
1712        - Added utolower configuration option to convert all usernames
1713          to lowercase during printing.
1714         
1715    - 1.15alpha15 :

1717        - Now includes the papwaitprinter.sh shell script to wait for
1718          AppleTalk enabled printers.
1719         
1720    - 1.16alpha14 :
1721   
1722        - Now printing on a printer not defined in the Quota Storage,
1723          results in the job being cancelled or stopped, depending
1724          on the printing system.
1725         
1726    - 1.16alpha13 :
1727   
1728        - Small bugfix wrt Python v2.1
1729       
1730        - If username is an empty string, user root is assumed.
1731       
1732        - 'postgresql' is not recognized anymore as a storage backend,
1733          you have to use 'pgstorage' instead. 'postgresql' used to
1734          be supported for compatibility with very old PyKota versions,
1735          this is not the case anymore.
1736         
1737    - 1.16alpha12 :
1738   
1739        - Job price added to job history, to keep accounting correct
1740          if a printer price per page or per job is modified and the
1741          history is not reset : the history would have given a false
1742          amount of money charged before the printer's prices were
1743          modified, this addition solves the problem.
1744         
1745    - 1.16alpha11 :
1746   
1747        - Some preliminary modifications to the database structure for
1748          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1749          database is now provided. LDAP attributes now support
1750          eq, pres and sub indexes.
1751         
1752        - Job history now contains additional informations : 
1753          number of copies, filename, title and print options.
1754         
1755    - 1.16alpha10 :
1756       
1757        - Some modifications done to external policy handling.
1758          See sample configuration file for details.
1759   
1760        - Spanish translation added.
1761       
1762    - 1.16alpha9 :
1763   
1764        - mailto can be set to external(...) to warn users above
1765          quota with any command of your choice (e.g. linpopup).
1766          Several parameters are available, see sample configuration
1767          file for details.
1768         
1769    - 1.16alpha8 :
1770   
1771        - Now cupspykota transmits SIGTERMS to the original 
1772          backend when the user deletes a job being processed.
1773         
1774        - The documentation is now licensed under the terms of the
1775          GNU GPL too.
1776         
1777    - 1.16alpha7 :
1778   
1779        - The CUPS backend is now fully functionnal (it seems).
1780       
1781        - From now on, the use of the pykota filter with CUPS
1782          is deprecated. The pykota filter still has to be
1783          used with LPRng though.
1784       
1785    - 1.16alpha6 :
1786   
1787        - Bug fixed : when edpykota was used to add a printer
1788          with no user or group name, a bad user/group name "*" was
1789          added to the database.
1790         
1791    - 1.16alpha5 :
1792   
1793        - New CUPS backend supports device enumeration !
1794          This means that NO manual CUPS configuration has to
1795          be done. All can now be done from CUPS web interface.
1796       
1797    - 1.16alpha4 :
1798   
1799        - New CUPS backend added.
1800       
1801    - 1.16alpha3 :
1802       
1803        - Minimal FAQ document added.

1812       
1813        - More complete error messages in case of LDAP operation failure.
1814       
1815    - 1.15 :
1816     
1817        - Documentation improved.
1818       
1819    - 1.15beta :
1820   
1821        - Command line tools now accept multiple printer
1822          names or wildcards, separated with commas.
1823         
1824    - 1.15alpha9 :
1825   
1826        - External policy can be used to auto-add unknown users
1827          and any other interesting things you may want to do.
1828          WARNING : You can't auto-add printers for now.
1829          They have to be created manually before.
1830          Look at sample configuration file for examples.
1831         
1832    - 1.15alpha8 :
1833   
1834        - Job history can be disabled if needed.
1835          This feature may be useful for people who use the LDAP
1836          backend and don't want their LDAP tree to grow out of
1837          control.
1838       
1839    - 1.15alpha7 :
1840   
1841        - More work done on caching wrt groups.
1842

1849        - Caching mechanism for all database queries.
1850
1851    - 1.15alpha4 :
1852   
1853        - Problem with Python 2.3 fixed. Needs some definitive
1854          modification.
1855         
1856    - 1.15alpha3 :
1857   
1858        - CGI script now tries to restrict view when the
1859          REMOTE_USER environment variable is set. This allows
1860          people to protect its use with .htaccess files.
1861          When unprotected, or if REMOTE_USER is 'root', then
1862          unrestricted access is granted.
1863          NB : REMOTE_USER is automatically set by the web server
1864          (e.g. Apache) when a page with restricted access is viewed.
1865         
1866    - 1.15alpha2 :
1867   
1868        - Better detection of LPRng.
1869       
1870        - Outputs a warning if printing system is unknown.
1871       
1872    - 1.15alpha1 :
1873   
1874        - Bug fix in SQL code.
1875       
1876    - 1.14 :
1877   
1878        - The PostgreSQL database connection is now always closed before
1879          exit. The LDAP database connection too, but it didn't suffer
1880          from the problem anyway, AFAICT.
1881       
1882    - 1.14beta2 :
1883   
1884        - An LDAP-specific configuration field was introduced, usermail.
1885          Use it to specify which LDAP attribute contains a valid email
1886          address for the user. See sample configuration file for
1887          details.
1888       
1889    - 1.14beta :
1890   
1891        - Two new LDAP-specific configuration fields were introduced,
1892          newuser and newgroup. Use them to specify if you want to add
1893          quota information to existing entries or elsewhere.
1894          See sample configuration file for details.
1895         
1896    - 1.14alpha9 :
1897   
1898        - Documentation improved.
1899       
1900        - pykotme now also prints the user's account balance value
1901          if the user is registered in the Quota Storage and his
1902          limiting factor is "balance".
1903         
1904    - 1.14alpha8 :
1905   
1906        - bin/waitprinter.sh is now included to wait for
1907          SNMP enabled printers to be idle again before
1908          asking for their internal page counter.
1909          See sample configuration file for details.
1910         
1911    - 1.14alpha7 :
1912   
1913        - edpykota now doesn't check if the user/group is above
1914          quota. The check is only done at print time. This
1915          prevents the sending of email messages when creating
1916          user quotas if quota is already reached at creation
1917          time.
1918         
1919    - 1.14alpha6 :
1920   
1921        - Configuration file split and moved to /etc/pykota/pykota.conf
1922          and /etc/pykota/pykotadmin.conf to prevent simple users to
1923          have Read/Write access to the Quota Database.
1924          Don't forget to :
1925         
1926                $ chmod 640 /etc/pykota/pykotadmin.conf
1927               
1928        - storageuser and storageuserpw configuration fields reintroduced
1929          for the same reason.
1930         
1931        - Code cleaning for future implementation of email addresses
1932          support in the PostgreSQL and LDAP backends.
1933         
1934    - 1.14alpha5 :
1935       
1936        - Big bug fixed when changing the prices for a printer
1937       
1938    - 1.14alpha4 :
1939   
1940        - When adding an user, the user itself and its account balance
1941          are now added in the same LDAP entry. Before they were added

1944    - 1.14alpha3 :
1945   
1946        - Email field added to PostgreSQL database. An upgrade script

1955        - Poor man's treshold included : users with a low account
1956          balance (below 1.0 by default, configurable) are sent
1957          a warning message.
1958         
1959        - All warning messages to users are now configurable. 
1960          NB : Warning messages to the administrator are not.
1961       
1962    - 1.13 :
1963   
1964        - Some small fixes wrt group handling.
1965       
1966        - The whole module code was passed through PyChecker and
1967          several small code inconsistencies were fixed,

1969         
1970    - 1.13alpha1 :
1971

2018       
2019        - repykota and warnpykota allow the root user to pass
2020          users or groups names on the command line. Users
2021          and groups names may contain wildcards.

2023        - repykota and warnpykota only reports or warns the
2024          current user when launched by non-root users.
2025         
2026        - Minor bug fixes. 
2027   
2028    - 1.09alpha1 :
2029   
2030        - More work on LDAP storage backend. Many options
2031          were added to /etc/pykota.conf to give some
2032          hints to the LDAP storage backend.
2033         
2034        - Severe database access optimizations were done by
2035          rewriting most of the Quota Storage backends drivers.

2044   
2045        - Code refactoring.
2046       
2047        - A single user/password pair is used to connect
2048          to the database backend. The storageuser configuration
2049          field, and its associated passwords storageuserpw, are
2050          not used anymore.
2051         
2052        - You can now set PyKota in debug mode, see sample configuration 
2053          file for details.
2054          WARNING : only Quota Storage backend queries are logged in
2055          debug mode, for now.
2056       
2057    - 1.08alpha7 :
2058   
2059        - Very latest LDAP schema.
2060       
2061        - Code enhancement wrt easy pluggability of PyKota attributes
2062          and object classes into an existing LDAP directory.
2063       
2064    - 1.08alpha6 :
2065   
2066        - Minor bug corrections
2067       
2068        - More work on LDAP : new schema
2069       
2070    - 1.08alpha5 :
2071   
2072        - More good work on LDAP storage.
2073          repykota now works reasonably well with the sample LDAP directory.
2074       
2075    - 1.08alpha4 :
2076   
2077        - LDAP schema included.
2078          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2079          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2080          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2081          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2082          MAILING LIST.
2083         
2084    - 1.08alpha3 :
2085   
2086        - External accounting methods were partly rewritten :
2087         
2088          - No more "broken pipe" should happen.
2089         
2090          - They now take care of the number of copies
2091            This may be unneeded though, if the postscript
2092            file already does this, because this would
2093            overcharge users (number of copies counted
2094            two times). NEEDS MORE TESTING.
2095           
2096          - The sample configuration file now contains 
2097            an external accounting method example which should
2098            work with all DSC compliant Postscript files.
2099           
2100        - Some small bugs were fixed.   
2101       
2102    - 1.08alpha2 :
2103   
2104        - Now works with net-snmp v5.0 and above.
2105          It already worked, but the sample configuration
2106          file didn't contain appropriate values...
2107       
2108    - 1.07 : Release of the Shame !
2109   
2110        - The external accounting methods driver was left out of
2111          the CVS tree. Nobody could use it since it wasn't included !
2112         
2113    - 1.06 :
2114   
2115        - Severe bug fixed : if you had a printer in
2116          power saving state which couldn't answer immediately,
2117          a bug was triggered.
2118          It was caused by a bad copy/paste which
2119          forgot to import a Python module at run time.
2120         
2121    - 1.05 :
2122   
2123        - External accounters are finally available !
2124          This means that you can plug any page accounting
2125          method you like by setting the appropriate
2126          'accounter' field in /etc/pykota.conf
2127          See the sample conf/pykota.conf.sample to
2128          learn how to do.
2129         
2130          NB : Both 'external' and 'stupid' accounting methods
2131               account a job size just before *this* job is
2132               sent to the printer.
2133               The original 'querying' method accounts a job
2134               size just before *the next* job is sent to
2135               the printer.
2136       
2137    - 1.05alpha3 :
2138   
2139        - A 'stupid' and unreliable accounting method was
2140          implemented to serve as an example on how to
2141          do this sort of things. This method only counts
2142          the 'showpage' statements in the input data.
2143          See sample configuration file for details.
2144          Pluggable accounting methods work, but I advise
2145          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2146          It is not reliable enough to be used.
2147          Use the 'querying' accounting method instead.
2148         
2149    - 1.05alpha2 :
2150   
2151        - Pluggable accounting methods.
2152       
2153        - Better error handling.
2154       
2155    - 1.05alpha1 :
2156   
2157        - SECURITY file added to help improve PyKota's security.
2158       
2159        - Extracting the printer's internal page counter is now
2160          tried several times, waiting several seconds between
2161          two tries. This lets the time to warm up for some printers
2162          which don't answer when they are sleeping (my Apple
2163          LaserWriter 16/600 PS is in this case, maybe others too)
2164         
2165        - Small display bug fixed in repykota
2166         
2167    - 1.04 :
2168   
2169        - Default print policy for users/groups unknown from
2170          the print quota system is now DENY instead of ALLOW,
2171          since ALLOW can generate inaccurate results
2172          (incorrect job sizes charged to the wrong persons)
2173         
2174        - LPRng support works !
2175       
2176        - A bug was introduced some time ago wrt printers' default
2177          policy for unknown users. It is now corrected.
2178       
2179        - repykota now displays prices per job and per page for each
2180          printer, if they are defined.
2181         
2182        - Minor display bug fixed in repykota.
2183       
2184        - Problem when running repykota with an empty database was fixed.
2185       
2186    - 1.03 :
2187   
2188        - Upgrade script included for earlier versions.
2189          Please look inside the initscripts subdirectory.
2190          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2191         
2192        - repykota now reports account balances too.
2193       
2194        - PyKota now has a nice logo, see the logos
2195          subdirectory.
2196       
2197        - Manual pages were finally updated.
2198       
2199        - Group quotas seem to work now !
2200       
2201        - The new database schema allows to keep an history of all
2202          jobs as well as charge users per page and/or per job,
2203          and track users' account balance.
2204         
2205        - edpykota now accepts much more command line options to 
2206          use the new functionnalities. See edpykota --help for
2207          details.
2208         
2209        - The installation script now allows to install the sample
2210          configuration file during first installation.
2211         
2212        - More group quota code works, but still not finished. 
2213       
2214        - The CGI script displays a link to PyKota's website.
2215       
2216        - The job history is now kept, this will allow per-period
2217          reports in the future.
2218         
2219        - After having modified the quota for an user with edpykota,
2220          a quota check is done to eventually warn the user/admin about
2221          a quota which is too low to print.
2222         
2223        - A workaround is provided for HP Printers : their internal
2224          page counter is only saved to NVRAM in a 10 increment, so
2225          if you switch them off and then on, the reported page counter
2226          may be lower than the real number of pages printed.
2227          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2228          We unconditionnally set the last job's page count to
2229          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2230          in this case.
2231          For a more accurate accounting, never switch your HP printers
2232          off.
2233         
2234        - A fix is provided for printers which only have a volatile 
2235          page counter (reset to 0 every time you switch the printer on)
2236          This should allow PyKota to work reasonably fine with HP Laserjet
2237          4L/5L/6L, not perfect, but better than nothing.
2238          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2239          For a more accurate accounting, never switch your HP printers
2240          off. This is untested, please report any problem.
2241         
2242        - A bug was fixed when edpykota --add was used with users who already
2243          had a quota on the specified printer.
2244         
2245        - A small display bug in repykota was introduced in preliminary
2246          1.03 versions, and fixed later on.
2247         
2248        - Some minor bugs which happened in rare situations were fixed.
2249       
2250        - Support for AppleTalk printers was added, see sample configuration
2251          file for details.
2252         
2253        - Users and group printing can now be controlled (limited) either by 
2254          print quota or by account balance.
2255       
2256    - 1.02 :
2257   
2258        - The installation script now checks for software availability
2259          and in case a software is missing asks the user if he
2260          wants to continue with the installation or abort it.
2261         
2262        - The configuration file pykota.conf is now expected to be
2263          found in /etc instead of in /etc/cups
2264          The installation script prompts the user to see if he
2265          wants to move an old configuration file to the new location
2266          if needed.
2267         
2268        - Improved documentation.
2269       
2270        - You can now set the tcp/ip port on which the Quota Storage
2271          Server is listening, see sample configuration file for details.
2272       
2273        - Better general error handling.
2274       
2275        - Upgrade script for pre 1.01 PostgreSQL database schema is now
2276          included as well.
2277       
2278    - 1.01 :
2279   
2280        - The configuration file now accepts an option   
2281          to choose the recipient(s) of the email messages :
2282         
2283            - DevNull means no one will receive them.
2284            - User means only the user will receive them.
2285            - Admin means only the admin will receive them.
2286            - Both means the User and the Admin will receive them.
2287           
2288        - The configuration file now uses hard-coded default values
2289          when an option is not set. See sample configuration file
2290          for details.
2291         
2292        - Manual pages are included since 1.00, but I forgot to   
2293          add this information to this file.
2294         
2295        - Redistribution terms for the official package have 
2296          softened and are now fully GPL compatible :
2297          unrestricted modification is now allowed even for
2298          the version number.
2299         
2300    - 1.00 :
2301   
2302        - edpykota now accepts a --noquota option. This
2303          disable quota checking while still doing page
2304          accounting. This is really useful for people
2305          who don't want to limit their users but want
2306          to know how much pages they print.
2307         
2308        - Some untested scripts were added to retrieve
2309          the life time page counter of non-SNMP printers.
2310         
2311        - Every directory now has a specific README file. 
2312       
2313    - 0.99 :
2314   
2315        - Under some circumstances while the user wasn't allowed
2316          to print, he didn't receive any email message. It is
2317          now fixed.
2318         
2319        - When an user wasn't allowed to print, the quota for
2320          the previous user wasn't updated. This is now fixed.
2321         
2322    - 0.98 :
2323   
2324        - Correctly handle the case where the printer is switched off.
2325       
2326        - Small bug wrt syslog fixed.
2327       
2328    - 0.97 :
2329   
2330        - edpykota accepts wildcards on its command line for users/groups too
2331          if the --add option is not set, e.g. :
2332         
2333              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
2334             
2335        - If no user name is passed at all, then a default wildcard of "*"
2336          which means apply the command on ALL users for this printer is used.
2337         
2338        - Small bug fixes.
2339       
2340    - 0.96 :
2341
2342        - Options requester, policy, admin, adminmail and gracedelay can now
2343          be set either globally or per printer. The printer option has
2344          priority if both are defined.
2345
2346        - More powerful configuration parser.
2347       
2348        - If all options are defined globally, there's no need to
2349          define a section for each printer in the configuration
2350          file anymore. Just define a [global] section and it's ok.
2351
2352    - 0.95 :
2353
2354        - External requesters for printers finally added.
2355
2356        - Full internationalization (english and french are supported)
2357 
2358        - More complete quota usage report
2359
2360        - CGI script to access to the quota usage report
2361
2362        - Several bugs fixed.
2363
2364
2365    - 0.9 :
2366
2367        - First public version
