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

65       
66    - 1.25alpha1 (2006-04-14) :
67   
68        - Make the MySQL schema work with old releases of MySQL.
69       
70        - Fixed several character encoding problems.
71         
72        - Ensures that the denied banners counter is properly initialized
73          with relationnal databases.
74         
75    - 1.24 (2006-04-08) :
76   
77        - Improved documentation and packaging stuff.
78       
79    - 1.24beta (2006-03-26) :
80   
81        - Finalized the pknotify command.
82       
83        - Updated the messages catalogs for translations.
84       
85    - 1.24alpha18 (2006-03-15) :
86   
87        - Now uses MIME encapsulation for email messages to avoid
88          some problems with 8 bits messages being rejected.
89         
90    - 1.24alpha17 (2006-03-06) :
91   
92        - Fixed a major problem in the PostgreSQL backend.
93       
94        - pknotify can now check a remote user's name and password.

96    - 1.24alpha16 (2006-03-02) :
97   
98        - Introduced the pknotify command line tool to dialog
99          with remote PyKotIcon applications.
100         
101    - 1.24alpha15 (2006-03-02) :
102       
103        - optimized pkbcodes, pkprinters and pkusers using edpykota as
104          the model.
105       
106        - 'edpykota --list' and 'pkusers --list' are now authorized
107          to mere mortal users, but the list is restricted to informations
108          about the current user.
109       
110        - Extended the functionnality of the 'onbackenderror' directive to
111          allow for configurable retries.
112         
113    - 1.24alpha14 :
114   
115        - Finished optimizations in edpykota and fixed some minor
116          problems with LDAP.
117         
118    - 1.24alpha13 :
119   
120        - Introduced the pkusers command line tool to manage users and 
121          users groups. This command doesn't deal with print quota entries,
122          which continue to be managed through the edpykota command line
123          tool.
124         
125        - Major rewrite and incompatible changes to command line options
126          in edpykota. This command now only deals with print quota
127          entries. Printers, users (or users groups) now have to be created
128          first using pkprinters or pkusers.
129         
130    - 1.24alpha12 :
131   
132        - Introduced the 'duplicatesdelay' directive to specify after
133          which duration two duplicate jobs are not considered duplicate
134          jobs anymore.
135         
136        - Introduced the 'balancezero' directive to specify any value 
137          as the balance limit instead of 0.0. This can allow admins to
138          give a few free credits to users, for example.
139         
140    - 1.24alpha11 :
141   
142        - Huge speed improvements when modifying billing codes and
143          printers.
144       
145        - Both pkbcodes and pkprinters now display the percent done
146          for all actions.
147         
148        - The pkinvoice invoice generator command line utility is now
149          included.
150         
151    - 1.24alpha10 :   
152   
153        - Huge speed improvements when deleting users, printers, and
154          billing codes.
155         
156    - 1.24alpha9 :
157   
158        - Preliminary support for MySQL, thanks to Matt Hyclak.
159       
160    - 1.24alpha8 :
161   
162        - The 'preaccounter' configuration directive was introduced to control
163          which parser to use for precomputation of the job's size. When unset,
164          the internal parser is used just like it was previously. See
165          conf/pykota.conf.sample for more details.
166         
167        - Now subprocesses launched through the overwrite_jobticket directive
168          can also output 'CANCEL', to represent the user's own choice to
169          cancel the print job.
170         
171    - 1.24alpha7 :
172     
173        - pkbanner now handles new print limiting modes correctly.
174       
175        - The cupspykota backend wrapper now accepts to be interrupted
176          with a kill -INT. This causes an immediate and clean abort
177          of the current print job.
178         
179        - Matt Hyclak contributed the possibility to store the printing
180          history in a MySQL database. See the contributed/ directory
181          for details.
182         
183        - Added 2006 to the copyright's years.
184       
185    - 1.24alpha6 :
186   
187        - Fixed internal SNMP and PJL handling code for very fast
188          printers : PyKota didn't see them going from 'idle'
189          to 'printing' to 'idle' again.
190         
191        - Now waitprinter.sh accepts SNMP version number and
192          community name as arguments, thanks to Brandon
193          Holbrook.
194         
195        - Now command line errors and Ctrl+C repectively cause
196          PyKota commands to exit with status -2 and -3.
197         
198    - 1.24alpha5 :
199   
200        - All command line tools now accept -A | --arguments filename.args
201          as a way to bypass the shell's maximal command line size :
202          just put each argument on a line by itself in a file, and
203          pass the file's name as the -A | --arguments command line
204          option's argument. For now this won't be documented in
205          commands' helps.
206         
207        - dumpykota can now dump the complete database in XML
208          format.
209         
210    - 1.24alpha4 :
211   
212        - Added support for the SQLite3 backend.
213          See pykota/initscripts/sqlite/README.sqlite
214       
215    - 1.24alpha3 :
216   
217        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
218          so we regain priviledges before running an external
219          mailto directive.
220       
221    - 1.24alpha2 :
222   
223        - Introduce the "onbackenderror" directive in pykota.conf, to
224          control if the user must be charged or not whenever a real
225          CUPS backend fails. The default value is 'nocharge'.
226          Set it to 'charge' if you think your users can cause a CUPS
227          backend to fail.
228         
229        - Now mark original backends related problems as such in the
230          printing history. Modified printquota.cgi and pykota.css
231          to make them be more visible.
232         
233    - 1.24alpha1 :
234   
235        - Fixed a problem which caused backend errors to be ignored.
236       
237        - The sample LDIF file now contains the two necessary user
238          entries to have an LDAP PyKota Admin and an LDAP PyKota
239          ReadOnly user. The sample configuration files were updated
240          to contain the default passwords used in the LDIF file.
241         
242        - dumpykota is now more strict when checking arguments.   
243       
244    - 1.23 :
245   
246        - Many minor bug fixes and code cleaning.
247       
248        - Improved documentation.
249       
250        - Added Polish translation.
251       
252        - Improved French and Swedish translations.
253       
254    - 1.23beta :
255   
256        - Now the mailto directive is honored in all cases where the job is
257          denied or a warning has to be issued, and the correct reason
258          can be sent back to the user.
259         
260        - The PYKOTAREASON environment variable, if defined, contains the 
261          textual reason why the job was denied or a warning has to be
262          issued.
263       
264    - 1.23alpha31 :
265   
266        - Added support for --maxjobsize, --passthrough and --nopassthrough
267          in pkprinters. These modes are now also honored when printing.
268         
269        - Allows the admin to restrict the number of print queues which will
270          be treated by pkturnkey by passing queues' names as additionnal
271          arguments on pkturnkey's command line.
272         
273        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
274          command line option.   
275         
276    - 1.23alpha30 :
277   
278        - Database changes : you MUST use upgrade-to-1.23.sql again if you
279          use PostgreSQL, or copy the new schema and restart your LDAP
280          server if you use LDAP.
281         
282        - The -C | --comment command line switch was added to edpykota to 
283          attach textual information to modifications done to a user's
284          account balance.
285         
286        - The -l | --limitby command line switch to edpykota was modified 
287          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
288          command's help or manual page for details.
289         
290        - The -i | --ingroups command line switch to repykota allows 
291          PyKota Administrators to only lists members of the specified
292          group or groups (separated with commas).
293         
294        - The -I | --increase command line switch to edpykota allows
295          to increase or decrease page limits.
296         
297        - Added the precomputed job's size and price to the history
298          for controlling purpose.
299       
300    - 1.23alpha29 :
301   
302        - Fixed a small problem with billing codes.
303       
304        - Exports some environment variables earlier, to render the script
305          launched by the overwrite_jobticket directive more powerful.
306         
307        - Now autopykota also creates print quota entries for the user on the
308          printers groups the current printer is a member of.
309         
310    - 1.23alpha28 :
311   
312        - Added users groups management to pkturnkey.
313       
314        - Fixed umask in setup script.
315       
316    - 1.23alpha27 :
317   
318        - Replaced the --dryrun command line option by the --force
319          command line option in pkturnkey, with exactly the opposite
320          effect (for security reasons).
321         
322    - 1.23alpha26 :
323   
324        - Allows parametrized pjl and snmp hardware accounting methods,
325          to be able to respectively set the TCP port and the SNMP
326          community.
327         
328    - 1.23alpha25 :
329

331       
332        - Improved pkturnkey's general usability.
333       
334        - Added a manpage for pkturnkey.
335       
336    - 1.23alpha24 :
337   
338        - Allows different databases to be used depending on the
339          user's rights. This allows PyKota admins to directly
340          use a master LDAP server for read+write, while letting
341          normal users using the replicas for readonly access.
342          NB : using different storage backends is also possible,
343          but you're on your own there.
344         
345    - 1.23alpha23 :
346   
347        - Fixed a problem with banner accounting.
348   
349        - Introduction of the new 'pkturnkey' command line tool.
350       
351    - 1.23alpha22 :
352   
353        - The cupspykota backend was almost entirely rewritten from scratch.
354          It's now much more readable, maintainable, etc...
355         
356        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
357          advised to download earlier releases or purchase the
358          PyKota v1.22HotFix1 Official release. LPRng support
359          MIGHT be re-added later.
360       
361    - 1.23alpha21 :
362     
363        - Fix for IPP requests which contain more than a single
364          job-originating-host-name attribute.
365         
366    - 1.23alpha20 :
367   
368        - Added the overwrite_jobticket directive. See pykota.conf.sample
369          for how to use it.
370         
371    - 1.23alpha19 :
372   
373        - Fixed an LDAP filtering problem when managing billing codes.
374       
375        - Added the unknown_billingcode directive. See pykota.conf.sample
376          for how to use it.
377       
378    - 1.23alpha18 :
379     
380        - Added the dump_bfd.php contribution.
381       
382        - Several fixes in the internal PJL accounter.
383       
384        - Now autopykota doesn't create unneeded print quota entries anymore.
385       
386        - Increased the timeout in the PJL hardware accounting code to
387          accomodate some printers (HP5000 at least).
388         
389    - 1.23alpha17 :
390   
391        - pkpgcounter is now distributed separately only. This
392          means that people must now download and install pkpgcounter
393          v1.56 or higher prior to being able to run PyKota.
394         
395        - Removed all the autoconf/automake stuff which was outdated 
396          and confusing.
397         
398    - 1.23alpha16 :
399     
400        - Extracted the GPL blurb from all commands' help, and use
401          a static version only once. This saves space big time, and
402          eases future translations.
403         
404    - 1.23alpha15 :
405   
406        - pkbcodes now works with the PostgreSQL backend.
407          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
408       
409    - 1.23alpha14 :
410   
411        - Logs a warning when the user/group doesn't exist when running
412          edpykota.
413         
414    - 1.23alpha13 :
415   
416        - Minor fix for user groups because of latest database changes.
417       
418    - 1.23alpha12 :
419   
420        - Big database changes, use the migration scripts !
421       
422    - 1.23alpha11 :
423   
424        - Small fix to the PCL3/4/5 parser for some drivers.
425       
426    - 1.23alpha10 :
427   
428        - Fixed a bad exception name in cupspykota when parsing IPP messages.
429       
430        - Improved the IPP messages module : it can now generate IPP messages
431          in addition to parsing them.
432       
433    - 1.23alpha9 :   
434   
435        - The denyduplicates directive now accepts a command line as an
436          argument beside yes/no. The command is launched and must
437          print either ALLOW or DENY to its standard output. Then the
438          job gets allowed or denied by PyKota.
439          This will allow user interaction in the near future.
440         
441        - Introduced the new 'striptitle' directive to remove ugly prefixes
442          from print job's titles whenever a new print job is submitted.
443         
444        - Fixed internal SNMP accounter for printers which only have a life time
445          page counter, and not a volatile page counter.
446         
447    - 1.23alpha8 :
448   
449        - The data dumper can now summarize payments and history with the
450          help of the --sum command line option (or checkbox in the CGI).
451         
452        - The message used when the job's filename, title and options are
453          hidden because of the privacy directive is now translated at
454          retrieval time, instead of at saving time.
455         
456        - Minor fix in the LDAP backend code. 
457         
458    - 1.23alpha7 :
459   
460        - Improvements to the internal PJL and SNMP accounter : now should
461          support more printers and waste less time.
462         
463    - 1.23alpha6 :
464   
465        - The data dumper's start= and end= date filtering options now
466          accept a positive or negative offset to be added to the special
467          keywords 'yesterday', 'today', 'now', 'tomorrow'.
468          e.g. : dumpykota --data history start=yesterday-5 end=today
469         
470    - 1.23alpha5 :
471   
472        - The data dumper's start= and end= date filtering options now accept
473          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
474         
475    - 1.23alpha4 :
476   
477        - The data dumper now accept start= and end= to specify the starting
478          and ending dates to dump the history.
479         
480    - 1.23alpha3 :

565       
566        - Fixes some problem for printers which directly go from

569         
570        - Some permissions settings may have prevented cupspykota
571          from parsing cupsd.conf, this is now fixed.

608    - 1.21alpha27 :
609   
610        - Allows software() (no arguments) to the software accounting
611          directive. This saves a lot of CPU since the job is not
612          parsed again : the precomputed size is used directly in this
613          case.
614         
615        - epykota's --prototype option now works fine with accounts
616          limited by balance.

630         
631        - Introduction of the new 'trustjobsize' configuration directive
632          to workaround some problematic printers. See the sample
633          configuration file for details.
634         
635    - 1.21alpha24 :
636   
637        - Big database structure changes. An upgrade script
638          is now included for PostgreSQL. LDAP users may just
639          want to copy the new schema in place.
640         
641        - edpykota now recognizes the -o | --overcharge command line
642          option to set an overcharging or undercharging factor
643          on each print job's cost for a particular user.
644         
645        - repykota's output format has changed an is not limited to 
646          80 characters wide anymore. People who used to parse
647          repykota's output in their own tools are strongly advised
648          to parse dumpykota's output instead.
649         
650        - Introduction of the new 'maxdenybanners' configuration directive
651          to allow up to N (the directive's value) deny banners to be
652          printed even if the print account is forbidden to print.
653         
654        - Better detection of the number of copies in the PostScript parser.

661       
662    - 1.21alpha22 :
663   
664        - edpykota's --delete command line option doesn't consider
665          '*' to be the default argument anymore :-)
666         
667    - 1.21alpha21 :
668   
669        - dumpykota.cgi can now be run as a normal user as opposed to
670          a PyKota administrator. No read access to pykotadmin.conf is
671          necessary anymore. This CGI scripts now honors the REMOTE_USER
672          environment variable just like printquota.cgi does, see
673          the file cgi-bin/README for details.
674          The command line tool dumpykota must still be run by a PyKota
675          administrator.
676         
677        - Fix exception's name error due to a change in recent versions
678          of PygreSQL.

682        - Big bug fix wrt the datelimit field which was never reset.
683         
684    - 1.21alpha19 :
685   
686        - Introduction of the new dumpykota.cgi CGI script, which
687          allows third party tools like phpPrintAnalyzer to be
688          interfaced in real time with PyKota. To use it you
689          may have to change your web server's configuration,
690          please see pykota/cgi-bin/README
691         
692    - 1.21alpha18 :
693   
694        - Now dumpykota can dump the job history into CUPS' page_log
695          format (even when the printing system is LPRng). This allows
696          people to use tools like PrintAnalyzer or phpPrintAnalyzer
697          (two completely different beasts) with PyKota.
698         
699    - 1.21alpha17 :
700     
701        - Fixed field type's name in XML dumps.

718        - dumpykota filtering capabilities are now supported within
719          the LDAP backend too.
720         
721    - 1.21alpha14 :
722   
723        - dumpykota now supports extended filtering possibilities
724          with the PostgreSQL backend (LDAP support will come soon).
725         
726    - 1.21alpha13 :
727   
728        - Added a --debug command line option to pkpgcounter, so
729          that people may see what really happens, and what will
730          be available in the future :-)
731         
732    - 1.21alpha12 :
733   
734        - Fixed a bug with non standard pkbanner command lines.

740   
741        - Now user and group print quota entries can be stored directly
742          below the user or group with the LDAP backend, using them
743          as branches. Thanks to Stefan Wold for the patch.
744          See the sample configuration file for details.
745         
746        - TLS is now supported with the LDAP backend. Thanks to Stefan
747          Wold for the patch.
748          See the sample configuration file for details.
749         
750        - edpkota now accepts the -U | --used value command line argument
751          to preset the page counters to an initial value. Thanks to
752          Wilson Roberto Afonso and Matt Hyclak for the patch.
753         
754    - 1.21alpha10 :
755   
756        - Now automatically reconnects up to three times if the LDAP server
757          returned an error, possibly due to a timeout.
758         
759    - 1.21alpha9 :
760   
761        - Now searches the configuration files in 'pykota' system user's
762          home directory. The 'pykota' system user and group have
763          to be created by the system administrator, and given
764          sufficient permissions to PyKota's configuration files.
765

809    - 1.21alpha1 :
810   
811        - added an IPP messages miniparser. Extraction of the client

814       
815    - 1.20 :
816   
817        - Version number changed.

889        - Now any PyKota administrator can use repykota and warnpykota
890          with additionnal arguments, not only the root user.
891

936         
937    - 1.20alpha15 :
938   
939        - LDAP pykotaAccountBalance objects were always created
940          attached to the pykotaUser objects. This is now
941          fixed and the value of balancebase in pykota.conf
942          is now correctly used.
943         
944    - 1.20alpha14 :
945

960          for this to work (tested with v3.4.2)
961         
962        - Increased delay between two loops iterations 
963          to 2 seconds in waitprinter.sh to diminish
964          CPU load.
965         
966    - 1.20alpha12 :

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

1452     
1453        - Fix for raw jobs with cupspykota
1454       
1455    - 1.18beta :
1456   
1457        - Small fix for new waitprinter.sh script
1458       
1459        - Better tracebacks on error conditions
1460       
1461        - Improved translations
1462       
1463        - Improved documentation
1464       
1465    - 1.18alpha15 :
1466
1467        - waitprinter.sh replaced by a new and possibly faster
1468          and more powerful one.
1469   
1470        - Names can now begin with a digit.

1476        - Catches more (all ?) problems with SMTP servers instead
1477          of breaking.
1478         
1479        - Italian translation added.
1480       
1481    - 1.18alpha13 :
1482   
1483        - Pre and Post hooks are now available in the pykota
1484          filter as well.
1485         
1486        - The pykota filter doesn't check last user's quota
1487          anymore when delayed hardware accounting is used :
1488          this will be done anyway the next time the last
1489          user will print again. This saves some database
1490          queries which are unneeded.
1491       
1492    - 1.18alpha12 :
1493   
1494        - Pre and Post hooks to external commands with many
1495          many environment variables available are useable
1496          from the cupspykota backend.
1497          See sample configuration file for details and help.
1498         
1499    - 1.18alpha11 :

1512       
1513        - Fix for empty user groups with LDAP.
1514       
1515        - Preliminary version of the snmpprinterstatus command added.
1516       
1517    - 1.18alpha8 :
1518   
1519        - Don't retrieve data when not needed.
1520          This avoids many database queries.
1521

1523   
1524        - New experimental ldapcache directive to improve
1525          LDAP caching.

1538          Peter Hawkins are now included in the project's tree.
1539         
1540        - Preliminary work on future low-level LDAP caching to speed
1541          up modifications (at least).
1542         
1543    - 1.18alpha4 :
1544   
1545        - Applied some of the modifications suggested by
1546          Peter Hawkins, for better Debian integration.
1547          Most notably cupspykota, pykota, and the shell
1548          scripts are now installed into /usr/share/pykota
1549          instead of into /usr/bin
1550          BEWARE : double check that your symbolic link
1551          to cupspykota is correct, and that your pykota.conf
1552          file use correct path for the shell scripts like
1553          waitprinter.sh and al.
1554         
1555        - pkhint command added, to help in configuring correct
1556          accounting method for PyKota.

1592          added to the documentation. Doesn't yet document v1.16
1593          though.
1594       
1595        - Portuguese Portuguese translation replaces Brazilian
1596          Portuguese Translation. Brazilian portuguese
1597          translation is still available under the 'br' locale.
1598       
1599    - 1.16beta3 :
1600

1604       
1605    - 1.16beta2 :
1606   
1607        - Small fix for job cancelling code while job already
1608          printing in CUPS backend.
1609         
1610        - Big fix wrt printing policies for unknown users. 
1611       
1612    - 1.16beta1 :
1613   
1614        - Manpages upgraded.
1615       
1616    - 1.16alpha26 :
1617   
1618        - Job price is now computed like this :
1619       
1620          SUM((NbPages * PricePerPage) + PricePerJob)
1621         
1622          For current printer and all the printers groups it is
1623          a member of, if any.
1624         
1625          This may be difficult to grasp, but offers unprecedented
1626          flexibility.
1627         
1628    - 1.16alpha25 :
1629   
1630        - Email address can be set at user creation time,

1642          automatically add printers on first print.
1643       
1644    - 1.16alpha23 :
1645   
1646        - Fixed potential accuracy problem if a user printed on
1647          several printers at the very same time.
1648

1666       
1667    - 1.16alpha18 :
1668   
1669        - Initial code for printer groups support. Printer groups have
1670          to be added with external tools like psql or gq for example.
1671          Printer groups seems to work fine with users. Untested with user
1672          groups for now.
1673
1674        - Several minor visual problems fixed in reports.
1675       
1676        - Fixed a bug in LDAP date handling.
1677

1682          for details.
1683       
1684        - Several environment variables are now exported when executing
1685          external commands (accounters, requesters, mailers) :
1686           
1687            PYKOTAUSERNAME => user who is printing
1688            PYKOTAPRINTERNAME => printer on which the job is being sent
1689            PYKOTATITLE => Job's title
1690            PYKOTAFILENAME => Job's filename
1691            PYKOTACOPIES => number of copies asked
1692            PYKOTAOPTIONS => print command options (-o with CUPS)
1693         
1694    - 1.16alpha17 :
1695   
1696        - Added portugues translation.
1697       
1698        - Major code refactoring in accounters.
1699       
1700    - 1.16alpha16 :
1701   
1702        - Code refactoring, and addition of a real HTML reporter, to
1703          have nice looking and useful web based reports (in the future).
1704       
1705        - Added utolower configuration option to convert all usernames
1706          to lowercase during printing.
1707         
1708    - 1.15alpha15 :
1709   
1710        - Now includes the papwaitprinter.sh shell script to wait for
1711          AppleTalk enabled printers.
1712         
1713    - 1.16alpha14 :
1714   
1715        - Now printing on a printer not defined in the Quota Storage,
1716          results in the job being cancelled or stopped, depending
1717          on the printing system.
1718         
1719    - 1.16alpha13 :
1720   
1721        - Small bugfix wrt Python v2.1
1722       
1723        - If username is an empty string, user root is assumed.
1724       
1725        - 'postgresql' is not recognized anymore as a storage backend,
1726          you have to use 'pgstorage' instead. 'postgresql' used to
1727          be supported for compatibility with very old PyKota versions,
1728          this is not the case anymore.
1729         
1730    - 1.16alpha12 :
1731   
1732        - Job price added to job history, to keep accounting correct
1733          if a printer price per page or per job is modified and the
1734          history is not reset : the history would have given a false
1735          amount of money charged before the printer's prices were
1736          modified, this addition solves the problem.
1737         
1738    - 1.16alpha11 :
1739   
1740        - Some preliminary modifications to the database structure for
1741          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1742          database is now provided. LDAP attributes now support
1743          eq, pres and sub indexes.
1744         
1745        - Job history now contains additional informations : 
1746          number of copies, filename, title and print options.
1747         
1748    - 1.16alpha10 :
1749       
1750        - Some modifications done to external policy handling.
1751          See sample configuration file for details.
1752   
1753        - Spanish translation added.
1754       
1755    - 1.16alpha9 :
1756   
1757        - mailto can be set to external(...) to warn users above
1758          quota with any command of your choice (e.g. linpopup).
1759          Several parameters are available, see sample configuration
1760          file for details.
1761         
1762    - 1.16alpha8 :
1763   
1764        - Now cupspykota transmits SIGTERMS to the original 
1765          backend when the user deletes a job being processed.
1766         
1767        - The documentation is now licensed under the terms of the
1768          GNU GPL too.
1769         
1770    - 1.16alpha7 :
1771   
1772        - The CUPS backend is now fully functionnal (it seems).
1773       
1774        - From now on, the use of the pykota filter with CUPS
1775          is deprecated. The pykota filter still has to be
1776          used with LPRng though.
1777       
1778    - 1.16alpha6 :
1779   
1780        - Bug fixed : when edpykota was used to add a printer
1781          with no user or group name, a bad user/group name "*" was
1782          added to the database.
1783         
1784    - 1.16alpha5 :
1785   
1786        - New CUPS backend supports device enumeration !
1787          This means that NO manual CUPS configuration has to
1788          be done. All can now be done from CUPS web interface.
1789       
1790    - 1.16alpha4 :
1791   
1792        - New CUPS backend added.
1793       
1794    - 1.16alpha3 :
1795       
1796        - Minimal FAQ document added.
1797

1805       
1806        - More complete error messages in case of LDAP operation failure.
1807       
1808    - 1.15 :
1809     
1810        - Documentation improved.
1811       
1812    - 1.15beta :
1813   
1814        - Command line tools now accept multiple printer
1815          names or wildcards, separated with commas.
1816         
1817    - 1.15alpha9 :
1818   
1819        - External policy can be used to auto-add unknown users
1820          and any other interesting things you may want to do.
1821          WARNING : You can't auto-add printers for now.
1822          They have to be created manually before.
1823          Look at sample configuration file for examples.
1824         
1825    - 1.15alpha8 :
1826   
1827        - Job history can be disabled if needed.
1828          This feature may be useful for people who use the LDAP
1829          backend and don't want their LDAP tree to grow out of
1830          control.
1831       
1832    - 1.15alpha7 :
1833   
1834        - More work done on caching wrt groups.

1842        - Caching mechanism for all database queries.
1843
1844    - 1.15alpha4 :
1845   
1846        - Problem with Python 2.3 fixed. Needs some definitive
1847          modification.
1848         
1849    - 1.15alpha3 :
1850   
1851        - CGI script now tries to restrict view when the
1852          REMOTE_USER environment variable is set. This allows
1853          people to protect its use with .htaccess files.
1854          When unprotected, or if REMOTE_USER is 'root', then
1855          unrestricted access is granted.
1856          NB : REMOTE_USER is automatically set by the web server
1857          (e.g. Apache) when a page with restricted access is viewed.
1858         
1859    - 1.15alpha2 :
1860   
1861        - Better detection of LPRng.
1862       
1863        - Outputs a warning if printing system is unknown.
1864       
1865    - 1.15alpha1 :
1866   
1867        - Bug fix in SQL code.
1868       
1869    - 1.14 :
1870   
1871        - The PostgreSQL database connection is now always closed before
1872          exit. The LDAP database connection too, but it didn't suffer
1873          from the problem anyway, AFAICT.
1874       
1875    - 1.14beta2 :
1876   
1877        - An LDAP-specific configuration field was introduced, usermail.
1878          Use it to specify which LDAP attribute contains a valid email
1879          address for the user. See sample configuration file for
1880          details.
1881       
1882    - 1.14beta :
1883   
1884        - Two new LDAP-specific configuration fields were introduced,
1885          newuser and newgroup. Use them to specify if you want to add
1886          quota information to existing entries or elsewhere.
1887          See sample configuration file for details.
1888         
1889    - 1.14alpha9 :
1890   
1891        - Documentation improved.
1892       
1893        - pykotme now also prints the user's account balance value
1894          if the user is registered in the Quota Storage and his
1895          limiting factor is "balance".
1896         
1897    - 1.14alpha8 :
1898   
1899        - bin/waitprinter.sh is now included to wait for
1900          SNMP enabled printers to be idle again before
1901          asking for their internal page counter.
1902          See sample configuration file for details.
1903         
1904    - 1.14alpha7 :
1905   
1906        - edpykota now doesn't check if the user/group is above
1907          quota. The check is only done at print time. This
1908          prevents the sending of email messages when creating
1909          user quotas if quota is already reached at creation
1910          time.
1911         
1912    - 1.14alpha6 :
1913   
1914        - Configuration file split and moved to /etc/pykota/pykota.conf
1915          and /etc/pykota/pykotadmin.conf to prevent simple users to
1916          have Read/Write access to the Quota Database.
1917          Don't forget to :
1918         
1919                $ chmod 640 /etc/pykota/pykotadmin.conf
1920               
1921        - storageuser and storageuserpw configuration fields reintroduced
1922          for the same reason.
1923         
1924        - Code cleaning for future implementation of email addresses
1925          support in the PostgreSQL and LDAP backends.
1926         
1927    - 1.14alpha5 :
1928       
1929        - Big bug fixed when changing the prices for a printer
1930       
1931    - 1.14alpha4 :
1932   
1933        - When adding an user, the user itself and its account balance
1934          are now added in the same LDAP entry. Before they were added
1935          as two different LDAP entries.
1936         
1937    - 1.14alpha3 :

2017          current user when launched by non-root users.
2018         
2019        - Minor bug fixes. 
2020   
2021    - 1.09alpha1 :
2022   
2023        - More work on LDAP storage backend. Many options
2024          were added to /etc/pykota.conf to give some
2025          hints to the LDAP storage backend.
2026         
2027        - Severe database access optimizations were done by

2038        - Code refactoring.
2039       
2040        - A single user/password pair is used to connect

2043          not used anymore.
2044         
2045        - You can now set PyKota in debug mode, see sample configuration 
2046          file for details.
2047          WARNING : only Quota Storage backend queries are logged in
2048          debug mode, for now.
2049       
2050    - 1.08alpha7 :
2051   
2052        - Very latest LDAP schema.
2053       
2054        - Code enhancement wrt easy pluggability of PyKota attributes
2055          and object classes into an existing LDAP directory.
2056       
2057    - 1.08alpha6 :
2058

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