Revision 1622, 42.9 kB (checked in by jalet, 20 years ago)

Added support for binary PostScript? through GhostScript? if native DSC
compliant PostScript? analyzer doesn't find any page. This is much
slower though, so native analyzer is tried first.

22PyKota NEWS :
23
24    - 1.19alpha35 :
25   
26        - Generic PDL analyzer now supports Binary PostScript documents
27          in addition to DSC compliant ones.
28       
29    - 1.19alpha34 :
30   
31        - LPRng support : software accounting seems to work fine,
32          but hardware accounting doesn't work yet.
33   
34    - 1.19alpha33 :
35   
36        - pykosd now accepts command line arguments. Enjoy !
37          NB : due to a bug in xosd, you need xosd version 2.2.8
38          or higher if you don't use the default C locale.
39         
40    - 1.19alpha32 :
41   
42        - Early (not working) version of the LPRng support rewrite.
43       
44        - Saner default configuration file.
45       
46    - 1.19alpha31 :
47   
48        - Fixed a double Python2.1 incompatibility with newer versions,
49          which prevented the PCL5 and the PCLXL parsers to work with
50          this older version of Python.
51         
52    - 1.19alpha30 :
53   
54        - Introduction of preliminary version of the pykosd command
55       
56        - Usernames, Groupnames and Printernames can now contain
57          ANY character, expected '/' and '@'.
58       
59        - Integrated most of the Debian work from Sergio
60          Gonz�z Gonz�z
61         
62    - 1.19alpha29 :
63   
64        - PCLXL parser should now correctly handle number of
65          copies set for each page.
66         
67        - Added testsuite for generic PDL analyzer.
68       
69        - Typo fixed in PCLXL parser.
70       
71        - Correctly dispatches error messages depending on the
72          situation : tools which can be run interactively will
73          ALWAYS output their logs to stderr, excepted for
74          their DEBUG messages, for which the "logger:"
75          directive as set in pykota.conf will be honored.
76          Tools which can't be run interactively will ALWAYS
77          honor the "logger:" directive as set in pykota.conf
78         
79    - 1.19alpha28 :
80   
81        - The description field for printers can now be set,
82          and is displayed in reports.
83         
84        - Fixed a small problem in SQL backend code.
85         
86        - Improved pkhint
87       
88        - First working PCL6 (aka PCLXL) parser !
89          Doesn't handle copies yet.
90       
91    - 1.19alpha27 :
92   
93        - Additionnal 10% speed increase in PCL5 parser for GhostScript
94          generated files (untested yet with other PCL files).
95         
96        - Reintroduced the use of mmap in PCL5 parser : this speedups
97          PCL5 parsing by almost 4 times.
98          This 4x with the 3x below give us in fact a twelvefold increase
99          in performance for PCL5 parsing !
100         
101        - The Python accelerator Psyco is now used if available
102          in the generic PDL parser : it speedups PCL5 parsing by
103          almost three times automagically.
104         
105    - 1.19alpha26 :
106   
107        - Fixed PCL5 parser according to the sources of rastertohp.
108       
109        - Fixed number of copies handling in PCL5 parser : the number
110          of copies could vary from page to page.
111         
112        - Added more debug information to PCLXL parser. 
113       
114    - 1.19alpha25 :
115   
116        - Added new "description" field to printers in both
117          PostgreSQL and LDAP. No code to handle this yet.
118         
119        - Reversed the fix for power save mode in printers : 
120          no paper or tray open would have caused people to
121          be undercharged.
122         
123        - Preliminary version of MySQL initialization script.
124         
125    - 1.19alpha24 :
126   
127        - Native PDF parsing code now works perfectly with
128          Python 2.1 and above, and is way faster than before.
129          GhostScript is not used anymore to convert PDF to PS,
130          because PDF is parsed directly.
131         
132    - 1.19alpha23 :
133   
134        - Fixed waitprinter.sh wrt PowerSave mode and some
135          printers. Thanks to Ryan Suarez.
136       
137        - Smart PDL analyzer now recognizes PDF too : two
138          PDF parsing methods are used : a native one which
139          is very fast but requires Python 2.3 or above, and
140          a slower one which uses Ghostscript. PyKota detects
141          automatically which method to use depending on your
142          version of Python.
143       
144        - All tracebacks now include PyKota's version number.
145         
146    - 1.19alpha22 :
147   
148        - Ensures that the file pointer for job's data is
149          reset to the start of the job's datas after the
150          job's size pre-computation phase.
151         
152        - Improved PostScript detection code for bad drivers
153          which don't correctly switch languages between PJL
154          and PS.
155       
156        - Even better debugging code.
157       
158    - 1.19alpha21 :
159   
160        - Additionnal check.
161       
162    - 1.19alpha20 :
163   
164        - More complete logging messages wrt accounters.
165       
166        - Now catches early failures occuring when the configuration
167          files are parsed.
168       
169    - 1.19alpha19 :
170   
171        - Fixed over-verbose exits when displaying help
172          or version.
173         
174        - Extended some PATH in the shell scripts 
175       
176        - Deleting an user now also deletes his payments history.
177       
178        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
179          cause problems.
180
181    - 1.19alpha18 :
182   
183        - History of payments is now stored in the database, and
184          updated each time an user's balance is modified with
185          edpykota --balance. This history represents each time
186          the user was given some positive or negative credit,
187          but doesn't reflect price paid for jobs, which appear
188          in the jobs history instead.
189         
190        - Jobs history web reports now include the job's size in
191          bytes. Also columns were reordered to render the report
192          more easily readable.
193         
194    - 1.19alpha17 :
195   
196        - Mysterious bug (program exited unexpectedly without leaving
197          any log message) which occured once in a while when
198          cancelling jobs should be fixed now.
199         
200        - New 'crashrecipient' directive. Disabled by 
201          default. See sample configuration file to see how
202          to activate it. It is suggested that you activate it.
203         
204        - New PYKOTAJOBSIZEBYTES environment variable exported, 
205          which contains the job's size in bytes. Empty jobs
206          are now denied. This value is now stored in the job
207          history (but not yet displayed from the web interface)
208         
209        - Preliminary work on payments storage : the PostgreSQL 
210          and LDAP schemas should be OK now, but no code is written
211          yet to support this functionnality.
212         
213    - 1.19alpha16 :
214   
215        - the newuser and newgroup LDAP specific directives now accept
216          a second parameter to attach(), "fail" or "warn". If no entry
217          is found to attach PyKota attributes to, and "fail" was used,
218          then action is aborted and program exits in error. If "warn"
219          is used, a new entry is created but a warning message is logged.
220         
221        - The job's originating hostname is now stored in the database,
222          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
223       
224    - 1.19alpha15 :
225   
226        - The old pykota filter is now removed. This means that
227          currently PyKota doesn't support LPRng anymore, but
228          LPRng support will be re-added, improved, in the near future.
229         
230    - 1.19alpha14 :
231   
232        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
233          are now exported as environment variables.
234         
235        - Heavy CPU usage is now completely fixed it seems, by
236          introducing some 0.01 second sleeping when nothing to do.
237         
238        - Pre-computation of the job's size is now only
239          done when enforcement is "STRICT", this saves
240          CPU for people who don't want to use this new
241          feature.
242         
243        - New 'enforcement' directive which accepts either
244          STRICT or LAXIST. See sample configuration file
245          for details.
246         
247    - 1.19alpha13 :
248   
249        - Get back to an old version of the polling loop which
250          worked fine, but non-optimally. Will be optimized
251          as time permits.
252         
253    - 1.19alpha12 :
254   
255        - Job's size is now precomputed unconditionnally using
256          the generic PDL analyzer.
257          NB : This value is not yet used to pre-allow/deny the
258          job.
259       
260    - 1.19alpha11 :
261   
262        - The pykota filter is now completely deprecated and
263          can't be used anymore. LPRng users MUST download
264          an older version of PyKota. CUPS users MUST use
265          cupspykota. Better support for LPRng will come
266          in the near future.
267         
268    - 1.19alpha10 :
269   
270        - pykotme now uses generic PDL Analyzer directly instead
271          of spawning a new process.
272         
273        - Improvements to generic PDL Analyzer.
274       
275        - 25% Speedup in PCL parser. Getting more of the Python version
276          will probably be difficult, since the completely table driven
277          parser I wrote is slower than the original algorithm. Then,
278          the original algorithm is still used for now.
279          Probable that more speed could be achieved using mmap, at the
280          expense of severe memory consumption.
281       
282        - configuration simplifications : the "accounter" directive's
283          'hardware' arguments now accepts what was in the "requester"
284          directive as it's content. The "requester" directive is not
285          supported anymore. See sample configuration file for details.
286       
287    - 1.19alpha9 :
288       
289        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
290       
291        - pykotaOptions LDAP attribute now accepts non-ascii characters
292          too.
293         
294        - First try at cupspykota main loop rewrite
295       
296    - 1.19alpha8 :
297   
298        - 'querying' accounting method is now called 'hardware'
299       
300        - 'external' accounting method is now called 'software'
301       
302        - 'stupid' accounting method doesn't exist anymore
303       
304        - 'snmp' requester doesn't exist anymore
305       
306        - code simplifications in external requester
307       
308    - 1.19alpha7 :
309     
310        - Database schema change (both LDAP and PostgreSQL) to
311          allow storage of the job-originating-hostname attribute.
312          An SQL upgrade script is present. The code is not yet
313          capable of setting/retrieving this attribute. Support
314          for this functionnality will be added in the future.
315         
316    - 1.19alpha6 :
317   
318        - problems connecting to SMTP servers are now catched.
319       
320        - pykotme now uses pkpgcounter to compute the size of the
321          job. This modification adds PCL5 and soon PCLXL (PCL6)
322          support. You can now get quotes for PCL in addition to
323          PostScript.
324         
325        - pkpgcounter now includes first try at PCLXL parser. 
326          It is currently disabled until it's finished.
327         
328    - 1.19alpha5 :
329   
330        - cupspykota polling loop fix for MacOSX (at least)
331       
332        - logging subsystem now logs PID too, to ease diagnosing
333          problems under heavy load.
334         
335        - pkpgcounter enhancements.
336       
337        - pkprinters --skipexisting now tells pkprinters to not
338          modify existing printers when --add is used.
339          pkprinters logs a warning message whenever --add is
340          used and a printer already exists.
341         
342        - LDAP schema now allows accented chars in pykotaFileName
343          and pykotaTitle attributes.
344       
345    - 1.19alpha4 :
346   
347        - a bad copy&paste prevented pkpgcounter to work at all, this
348          is now fixed.
349         
350        - improved PCL support in pkpgcounter, with the use of
351          HP PCL/PJL Reference Set
352          PCL5 Printer Language Technical Quick Reference Guide
353       
354        - pkpgcounter now uses mmap to speed things up : duration
355          is halved with the sample 87 pages PCL document I use for
356          testing.
357         
358    - 1.19alpha3 :
359   
360        - pkprinters now accepts the --list command line argument
361          to list informations about printers.
362         
363    - 1.19alpha2 :
364   
365        - pkpgcounter is now included as a smart external
366          accounter which can handle both PostScript and PCL.
367         
368    - 1.19alpha1 :
369   
370        - PYKOTALIMITBY environment variable is now exported too.
371       
372        - Inclusion of Michele Baldessari's work on autotools.
373       
374    - 1.18 :
375   
376        - Improved documentation
377       
378    - 1.18beta2 :
379     
380        - Fix for raw jobs with cupspykota
381       
382    - 1.18beta :
383   
384        - Small fix for new waitprinter.sh script
385       
386        - Better tracebacks on error conditions
387       
388        - Improved translations
389       
390        - Improved documentation
391       
392    - 1.18alpha15 :
393
394        - waitprinter.sh replaced by a new and possibly faster
395          and more powerful one.
396   
397        - Names can now begin with a digit.
398       
399        - Stability improvement for quotas set on printers groups.
400       
401    - 1.18alpha14 :
402   
403        - Catches more (all ?) problems with SMTP servers instead
404          of breaking.
405         
406        - Italian translation added.
407       
408    - 1.18alpha13 :
409   
410        - Pre and Post hooks are now available in the pykota
411          filter as well.
412         
413        - The pykota filter doesn't check last user's quota
414          anymore when delayed hardware accounting is used :
415          this will be done anyway the next time the last
416          user will print again. This saves some database
417          queries which are unneeded.
418       
419    - 1.18alpha12 :
420   
421        - Pre and Post hooks to external commands with many
422          many environment variables available are useable
423          from the cupspykota backend.
424          See sample configuration file for details and help.
425         
426    - 1.18alpha11 :
427   
428        - Hopefully final fix wrt groups (users and printers)
429       
430    - 1.18alpha10 :
431   
432        - Fixed nested printer groups accounting.
433       
434        - Fixed user groups + printer groups problem.
435       
436    - 1.18alpha9 :
437   
438        - Fix for LDAP problem when job price was 0.
439       
440        - Fix for empty user groups with LDAP.
441       
442        - Preliminary version of the snmpprinterstatus command added.
443       
444    - 1.18alpha8 :
445   
446        - Don't retrieve data when not needed.
447          This avoids many database queries.
448       
449    - 1.18alpha7 :
450   
451        - New experimental ldapcache directive to improve
452          LDAP caching.
453         
454    - 1.18alpha6 :
455       
456        - New configuration directive added : maildomain
457          to specify the domain to send mail to when user
458          email address is not set in PyKota database.
459         
460        - More complete email message headers. 
461         
462    - 1.18alpha5 :
463   
464        - Debian packaging specific files, contributed by
465          Peter Hawkins are now included in the project's tree.
466         
467        - Preliminary work on future low-level LDAP caching to speed
468          up modifications (at least).
469         
470    - 1.18alpha4 :
471   
472        - Applied some of the modifications suggested by
473          Peter Hawkins, for better Debian integration.
474          Most notably cupspykota, pykota, and the shell
475          scripts are now installed into /usr/share/pykota
476          instead of into /usr/bin
477          BEWARE : double check that your symbolic link
478          to cupspykota is correct, and that your pykota.conf
479          file use correct path for the shell scripts like
480          waitprinter.sh and al.
481         
482        - pkhint command added, to help in configuring correct
483          accounting method for PyKota.
484         
485    - 1.18alpha3 :
486   
487        - Fixed a rare bug in cupspykota backend which gave
488          incorrect "CUPS backend died abnormally" messages.
489       
490    - 1.18alpha2 :
491   
492        - Added the pkprinters command line tool to manage printers
493          exclusively.
494       
495    - 1.18alpha1 :
496   
497        - Preliminary work on Relationnal Database Independance.
498       
499        - Sample report made from OpenOffice.org added as PDF and SXC.

549          For current printer and all the printers groups it is
550          a member of, if any.
551         
552          This may be difficult to grasp, but offers unprecedented

613           
614            PYKOTAUSERNAME => user who is printing
615            PYKOTAPRINTERNAME => printer on which the job is being sent
616            PYKOTATITLE => Job's title
617            PYKOTAFILENAME => Job's filename
618            PYKOTACOPIES => number of copies asked

637        - Now includes the papwaitprinter.sh shell script to wait for
638          AppleTalk enabled printers.
639         
640    - 1.16alpha14 :
641   
642        - Now printing on a printer not defined in the Quota Storage,
643          results in the job being cancelled or stopped, depending
644          on the printing system.
645         
646    - 1.16alpha13 :
647   
648        - Small bugfix wrt Python v2.1
649       
650        - If username is an empty string, user root is assumed.
651       
652        - 'postgresql' is not recognized anymore as a storage backend,
653          you have to use 'pgstorage' instead. 'postgresql' used to
654          be supported for compatibility with very old PyKota versions,
655          this is not the case anymore.
656         
657    - 1.16alpha12 :
658   
659        - Job price added to job history, to keep accounting correct
660          if a printer price per page or per job is modified and the
661          history is not reset : the history would have given a false
662          amount of money charged before the printer's prices were
663          modified, this addition solves the problem.
664         
665    - 1.16alpha11 :
666   
667        - Some preliminary modifications to the database structure for
668          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
669          database is now provided. LDAP attributes now support
670          eq, pres and sub indexes.
671         
672        - Job history now contains additional informations : 
673          number of copies, filename, title and print options.
674         
675    - 1.16alpha10 :
676       
677        - Some modifications done to external policy handling.
678          See sample configuration file for details.
679   
680        - Spanish translation added.
681       
682    - 1.16alpha9 :
683   
684        - mailto can be set to external(...) to warn users above
685          quota with any command of your choice (e.g. linpopup).
686          Several parameters are available, see sample configuration
687          file for details.
688         
689    - 1.16alpha8 :
690   
691        - Now cupspykota transmits SIGTERMS to the original

698   
699        - The CUPS backend is now fully functionnal (it seems).
700       
701        - From now on, the use of the pykota filter with CUPS
702          is deprecated. The pykota filter still has to be
703          used with LPRng though.
704       
705    - 1.16alpha6 :
706   
707        - Bug fixed : when edpykota was used to add a printer
708          with no user or group name, a bad user/group name "*" was
709          added to the database.
710         
711    - 1.16alpha5 :
712   
713        - New CUPS backend supports device enumeration !
714          This means that NO manual CUPS configuration has to
715          be done. All can now be done from CUPS web interface.
716       
717    - 1.16alpha4 :
718   
719        - New CUPS backend added.
720

741        - Command line tools now accept multiple printer
742          names or wildcards, separated with commas.
743         
744    - 1.15alpha9 :
745   
746        - External policy can be used to auto-add unknown users
747          and any other interesting things you may want to do.
748          WARNING : You can't auto-add printers for now.
749          They have to be created manually before.
750          Look at sample configuration file for examples.
751         
752    - 1.15alpha8 :
753   
754        - Job history can be disabled if needed.
755          This feature may be useful for people who use the LDAP
756          backend and don't want their LDAP tree to grow out of
757          control.
758       
759    - 1.15alpha7 :
760   
761        - More work done on caching wrt groups.

772   
773        - Problem with Python 2.3 fixed. Needs some definitive
774          modification.
775         
776    - 1.15alpha3 :
777   
778        - CGI script now tries to restrict view when the
779          REMOTE_USER environment variable is set. This allows
780          people to protect its use with .htaccess files.
781          When unprotected, or if REMOTE_USER is 'root', then
782          unrestricted access is granted.
783          NB : REMOTE_USER is automatically set by the web server
784          (e.g. Apache) when a page with restricted access is viewed.
785         
786    - 1.15alpha2 :
787   
788        - Better detection of LPRng.
789       
790        - Outputs a warning if printing system is unknown.
791

795       
796    - 1.14 :
797   
798        - The PostgreSQL database connection is now always closed before
799          exit. The LDAP database connection too, but it didn't suffer
800          from the problem anyway, AFAICT.
801       
802    - 1.14beta2 :
803   
804        - An LDAP-specific configuration field was introduced, usermail.
805          Use it to specify which LDAP attribute contains a valid email
806          address for the user. See sample configuration file for
807          details.
808       
809    - 1.14beta :
810   
811        - Two new LDAP-specific configuration fields were introduced,
812          newuser and newgroup. Use them to specify if you want to add
813          quota information to existing entries or elsewhere.
814          See sample configuration file for details.
815         
816    - 1.14alpha9 :
817   
818        - Documentation improved.
819       
820        - pykotme now also prints the user's account balance value
821          if the user is registered in the Quota Storage and his
822          limiting factor is "balance".
823         
824    - 1.14alpha8 :
825   
826        - bin/waitprinter.sh is now included to wait for
827          SNMP enabled printers to be idle again before
828          asking for their internal page counter.
829          See sample configuration file for details.
830         
831    - 1.14alpha7 :
832   
833        - edpykota now doesn't check if the user/group is above
834          quota. The check is only done at print time. This
835          prevents the sending of email messages when creating
836          user quotas if quota is already reached at creation
837          time.
838         
839    - 1.14alpha6 :
840   
841        - Configuration file split and moved to /etc/pykota/pykota.conf
842          and /etc/pykota/pykotadmin.conf to prevent simple users to
843          have Read/Write access to the Quota Database.
844          Don't forget to :
845         
846                $ chmod 640 /etc/pykota/pykotadmin.conf
847               
848        - storageuser and storageuserpw configuration fields reintroduced
849          for the same reason.
850         
851        - Code cleaning for future implementation of email addresses
852          support in the PostgreSQL and LDAP backends.
853         
854    - 1.14alpha5 :
855       
856        - Big bug fixed when changing the prices for a printer
857       
858    - 1.14alpha4 :
859   
860        - When adding an user, the user itself and its account balance
861          are now added in the same LDAP entry. Before they were added
862          as two different LDAP entries.
863         
864    - 1.14alpha3 :
865   
866        - Email field added to PostgreSQL database. An upgrade script
867          is included in initscripts/postgresql.
868       
869    - 1.14alpha2 :
870   
871        - Typo fixed when using the --prototype option to edpykota
872       
873    - 1.14alpha1 :
874

876          balance (below 1.0 by default, configurable) are sent
877          a warning message.
878         
879        - All warning messages to users are now configurable. 
880          NB : Warning messages to the administrator are not.
881       
882    - 1.13 :
883   
884        - Some small fixes wrt group handling.
885       
886        - The whole module code was passed through PyChecker and
887          several small code inconsistencies were fixed,
888          as well as a bug in the groups code.
889         
890    - 1.13alpha1 :
891

937        - LDAP backend works !
938       
939        - repykota and warnpykota allow the root user to pass
940          users or groups names on the command line. Users
941          and groups names may contain wildcards.
942         
943        - repykota and warnpykota only reports or warns the
944          current user when launched by non-root users.
945         
946        - Minor bug fixes. 
947   
948    - 1.09alpha1 :
949   
950        - More work on LDAP storage backend. Many options
951          were added to /etc/pykota.conf to give some
952          hints to the LDAP storage backend.
953         
954        - Severe database access optimizations were done by
955          rewriting most of the Quota Storage backends drivers.
956     
957    - 1.08 :
958   
959        - Major bug fix wrt LPRng support for remote jobs.
960

963    - 1.08alpha8 :
964   
965        - Code refactoring.
966       
967        - A single user/password pair is used to connect
968          to the database backend. The storageuser configuration
969          field, and its associated passwords storageuserpw, are
970          not used anymore.
971         
972        - You can now set PyKota in debug mode, see sample configuration 
973          file for details.
974          WARNING : only Quota Storage backend queries are logged in
975          debug mode, for now.
976       
977    - 1.08alpha7 :
978   
979        - Very latest LDAP schema.

994       
995    - 1.08alpha4 :
996   
997        - LDAP schema included.
998          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
999          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1000          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1001          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1002          MAILING LIST.
1003         
1004    - 1.08alpha3 :
1005   
1006        - External accounting methods were partly rewritten :
1007         
1008          - No more "broken pipe" should happen.
1009         
1010          - They now take care of the number of copies
1011            This may be unneeded though, if the postscript
1012            file already does this, because this would
1013            overcharge users (number of copies counted
1014            two times). NEEDS MORE TESTING.
1015           
1016          - The sample configuration file now contains 
1017            an external accounting method example which should
1018            work with all DSC compliant Postscript files.
1019           
1020        - Some small bugs were fixed.   
1021       
1022    - 1.08alpha2 :
1023   
1024        - Now works with net-snmp v5.0 and above.
1025          It already worked, but the sample configuration
1026          file didn't contain appropriate values...
1027       
1028    - 1.07 : Release of the Shame !
1029   
1030        - The external accounting methods driver was left out of
1031          the CVS tree. Nobody could use it since it wasn't included !
1032         
1033    - 1.06 :
1034   
1035        - Severe bug fixed : if you had a printer in
1036          power saving state which couldn't answer immediately,
1037          a bug was triggered.
1038          It was caused by a bad copy/paste which
1039          forgot to import a Python module at run time.
1040         
1041    - 1.05 :
1042   
1043        - External accounters are finally available !
1044          This means that you can plug any page accounting
1045          method you like by setting the appropriate
1046          'accounter' field in /etc/pykota.conf
1047          See the sample conf/pykota.conf.sample to
1048          learn how to do.
1049         
1050          NB : Both 'external' and 'stupid' accounting methods
1051               account a job size just before *this* job is
1052               sent to the printer.
1053               The original 'querying' method accounts a job
1054               size just before *the next* job is sent to
1055               the printer.
1056       
1057    - 1.05alpha3 :
1058   
1059        - A 'stupid' and unreliable accounting method was
1060          implemented to serve as an example on how to
1061          do this sort of things. This method only counts
1062          the 'showpage' statements in the input data.
1063          See sample configuration file for details.
1064          Pluggable accounting methods work, but I advise
1065          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1066          It is not reliable enough to be used.
1067          Use the 'querying' accounting method instead.
1068         
1069    - 1.05alpha2 :
1070   
1071        - Pluggable accounting methods.
1072       
1073        - Better error handling.
1074       
1075    - 1.05alpha1 :
1076   
1077        - SECURITY file added to help improve PyKota's security.
1078       
1079        - Extracting the printer's internal page counter is now
1080          tried several times, waiting several seconds between
1081          two tries. This lets the time to warm up for some printers
1082          which don't answer when they are sleeping (my Apple
1083          LaserWriter 16/600 PS is in this case, maybe others too)
1084         
1085        - Small display bug fixed in repykota
1086         
1087    - 1.04 :
1088   
1089        - Default print policy for users/groups unknown from
1090          the print quota system is now DENY instead of ALLOW,
1091          since ALLOW can generate inaccurate results
1092          (incorrect job sizes charged to the wrong persons)
1093         
1094        - LPRng support works !
1095       
1096        - A bug was introduced some time ago wrt printers' default
1097          policy for unknown users. It is now corrected.
1098       
1099        - repykota now displays prices per job and per page for each
1100          printer, if they are defined.
1101         
1102        - Minor display bug fixed in repykota.
1103       
1104        - Problem when running repykota with an empty database was fixed.
1105       
1106    - 1.03 :
1107   
1108        - Upgrade script included for earlier versions.
1109          Please look inside the initscripts subdirectory.
1110          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1111         
1112        - repykota now reports account balances too.
1113       
1114        - PyKota now has a nice logo, see the logos
1115          subdirectory.
1116       
1117        - Manual pages were finally updated.
1118       
1119        - Group quotas seem to work now !
1120       
1121        - The new database schema allows to keep an history of all
1122          jobs as well as charge users per page and/or per job,
1123          and track users' account balance.
1124         
1125        - edpykota now accepts much more command line options to 
1126          use the new functionnalities. See edpykota --help for
1127          details.
1128         
1129        - The installation script now allows to install the sample
1130          configuration file during first installation.
1131         
1132        - More group quota code works, but still not finished. 
1133       
1134        - The CGI script displays a link to PyKota's website.
1135       
1136        - The job history is now kept, this will allow per-period
1137          reports in the future.
1138         
1139        - After having modified the quota for an user with edpykota,
1140          a quota check is done to eventually warn the user/admin about
1141          a quota which is too low to print.
1142         
1143        - A workaround is provided for HP Printers : their internal
1144          page counter is only saved to NVRAM in a 10 increment, so
1145          if you switch them off and then on, the reported page counter
1146          may be lower than the real number of pages printed.
1147          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1148          We unconditionnally set the last job's page count to
1149          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1150          in this case.
1151          For a more accurate accounting, never switch your HP printers
1152          off.
1153         
1154        - A fix is provided for printers which only have a volatile 
1155          page counter (reset to 0 every time you switch the printer on)
1156          This should allow PyKota to work reasonably fine with HP Laserjet
1157          4L/5L/6L, not perfect, but better than nothing.
1158          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1159          For a more accurate accounting, never switch your HP printers
1160          off. This is untested, please report any problem.
1161         
1162        - A bug was fixed when edpykota --add was used with users who already
1163          had a quota on the specified printer.
1164         
1165        - A small display bug in repykota was introduced in preliminary
1166          1.03 versions, and fixed later on.
1167         
1168        - Some minor bugs which happened in rare situations were fixed.
1169       
1170        - Support for AppleTalk printers was added, see sample configuration
1171          file for details.
1172         
1173        - Users and group printing can now be controlled (limited) either by 
1174          print quota or by account balance.
1175       
1176    - 1.02 :
1177   
1178        - The installation script now checks for software availability
1179          and in case a software is missing asks the user if he
1180          wants to continue with the installation or abort it.
1181         
1182        - The configuration file pykota.conf is now expected to be
1183          found in /etc instead of in /etc/cups
1184          The installation script prompts the user to see if he
1185          wants to move an old configuration file to the new location
1186          if needed.
1187         
1188        - Improved documentation.
1189       
1190        - You can now set the tcp/ip port on which the Quota Storage
1191          Server is listening, see sample configuration file for details.
1192       
1193        - Better general error handling.
1194       
1195        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1196          included as well.
1197       
1198    - 1.01 :
1199   
1200        - The configuration file now accepts an option   
1201          to choose the recipient(s) of the email messages :
1202         
1203            - DevNull means no one will receive them.
1204            - User means only the user will receive them.
1205            - Admin means only the admin will receive them.
1206            - Both means the User and the Admin will receive them.
1207           
1208        - The configuration file now uses hard-coded default values
1209          when an option is not set. See sample configuration file
1210          for details.
1211         
1212        - Manual pages are included since 1.00, but I forgot to   
1213          add this information to this file.
1214         
1215        - Redistribution terms for the official package have 
1216          softened and are now fully GPL compatible :
1217          unrestricted modification is now allowed even for
1218          the version number.
1219         
1220    - 1.00 :
1221   
1222        - edpykota now accepts a --noquota option. This
1223          disable quota checking while still doing page
1224          accounting. This is really useful for people
1225          who don't want to limit their users but want
1226          to know how much pages they print.
1227         
1228        - Some untested scripts were added to retrieve
1229          the life time page counter of non-SNMP printers.
1230         
1231        - Every directory now has a specific README file. 
1232       
1233    - 0.99 :
1234   
1235        - Under some circumstances while the user wasn't allowed
1236          to print, he didn't receive any email message. It is
1237          now fixed.
1238         
1239        - When an user wasn't allowed to print, the quota for
1240          the previous user wasn't updated. This is now fixed.
1241         
1242    - 0.98 :
1243   
1244        - Correctly handle the case where the printer is switched off.
1245       
1246        - Small bug wrt syslog fixed.
1247       
1248    - 0.97 :
1249   
1250        - edpykota accepts wildcards on its command line for users/groups too
1251          if the --add option is not set, e.g. :
1252         
1253              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1254             
1255        - If no user name is passed at all, then a default wildcard of "*"
1256          which means apply the command on ALL users for this printer is used.
1257         
1258        - Small bug fixes.
1259       
1260    - 0.96 :
1261
1262        - Options requester, policy, admin, adminmail and gracedelay can now
1263          be set either globally or per printer. The printer option has
1264          priority if both are defined.
1265
1266        - More powerful configuration parser.
1267       
1268        - If all options are defined globally, there's no need to
1269          define a section for each printer in the configuration
1270          file anymore. Just define a [global] section and it's ok.
1271
1272    - 0.95 :
1273
1274        - External requesters for printers finally added.
1275
1276        - Full internationalization (english and french are supported)
1277 
1278        - More complete quota usage report
1279
1280        - CGI script to access to the quota usage report
1281
1282        - Several bugs fixed.
1283
1284
1285    - 0.9 :
1286
1287        - First public version
