31   
32        - Fixed job's data file detection code for LPRng.
33       
34        - Fixed a problem with PJL and PowerSave mode,

43         
44    - 1.21alpha2 :
45   
46        - Installation script is now non interactive again, as it should
47          have stayed from the beginning. Dependencies checking can

49         
50    - 1.21alpha1 :
51   
52        - added an IPP messages miniparser. Extraction of the client
53          hostname is now considered to be fiable, at least until

66        - Greek translation was finalized.
67       
68        - For urgent legal reasons, a "privacy" directive has been added
69          to pykota.conf, to hide jobs' title, filename and options
70          in the history.
71         
72        - Minor changes in the debian directory.
73       
74    - 1.20alpha27 :
75   
76        - Fixed many problems with translation files. In particular
77          the brasilian portuguese translation file was incorrectly
78          installed into the french "breton" locale directory.
79         
80        - Finished French translation. 
81         
82    - 1.20alpha26 :
83   
84        - LPRng support code should now better detect network
85          printers' hostnames or IP addresses.
86         
87        - Fix for recently introduced bug in LPRng support.
88       
89        - Fix for incorrect locale setting when starting.
90       
91    - 1.20alpha25 :
92   
93        - pkprinters allows --list to normal users, but require user
94          to be a PyKota administrator when another command line
95          option is used.
96         
97        - pkhint doesn't use absolute path to search for helper commands
98          anymore.
99         
100        - Spanish translation ready for 1.20.   
101       
102    - 1.20alpha24 :
103   
104        - Now warnpykota only warns users limited by balance once.
105       
106        - Now warnpykota only warns users who have ever printed,
107          to not cause confusion to users who have just opened
108          their account.
109       
110        - Prepared help messages for translations.
111       
112    - 1.20alpha23 :
113   
114        - Add workaround for locale problem.
115       
116    - 1.20alpha22 :
117

123       
124    - 1.20alpha21 :
125   
126        - Now dumpykota refuses to launch if the current user is not
127          a PyKota administrator (a PyKota administrator is an user
128          allowed to read the pykotadmin.conf file).
129         
130        - Now any PyKota administrator can use repykota and warnpykota
131          with additionnal arguments, not only the root user.
132         
133        - Improved documentation a bit.
134       
135    - 1.20alpha20 :
136   
137        - Reduced delay in internal SNMP and PJL_over_TCP handlers
138          from 2 to 1 second.
139       
140        - dumpykota can now output XML.
141       
142    - 1.20alpha19 :
143   
144        - Improved user groups and user groups quotas dumps in dumpykota.
145       
146        - Finished implementation of LDAP support in dumpykota.
147       
148        - The md5 sum of the job's datas is now available as an
149          hexadecimal digest in the PYKOTAMD5SUM environment variable.
150         
151        - The description, filename, title, and options fields
152          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
153          Proper charset is used during extraction from the database.
154         
155    - 1.20alpha18 :
156   
157        - Experimental autopykota command to initialize user
158          account and quota entries on first print while not
159          resetting the balance value if not needed.
160         
161        - Added the new "winbind_separator" directive to strip
162          out the Samba/Winbind domain name while printing if
163          needed (Off by default).
164         
165    - 1.20alpha17 :
166   
167        - Added --hardreset command line option to edpykota.
168       
169        - Fixed problem with accented chars in title, filename
170          or options and LDAP backend.
171         
172    - 1.20alpha16 :
173   
174        - Internal handling of socket based PJL queries over
175          port tcp/9100 is now available with the magic
176          'pjl' value in the hardware accounter.
177         
178    - 1.20alpha15 :
179   
180        - LDAP pykotaAccountBalance objects were always created
181          attached to the pykotaUser objects. This is now
182          fixed and the value of balancebase in pykota.conf
183          is now correctly used.
184         
185    - 1.20alpha14 :
186   
187        - Belgian translations added (copy of the french ones).
188       
189        - External hardware accounter now loops until
190          a result can be read correctly.
191         
192        - pkhint now suggest the internal snmp handling instead
193          of the external one.
194         
195    - 1.20alpha13 :
196     
197        - Hardware accounter now accepts the special
198          'snmp' value, meaning ALL is done from main code
199          without launching any subprocess.
200          You need the http://pysnmp.sf.net Python module
201          for this to work (tested with v3.4.2)
202         
203        - Increased delay between two loops iterations 
204          to 2 seconds in waitprinter.sh to diminish
205          CPU load.
206         
207    - 1.20alpha12 :
208   
209        - waitprinter.sh rewritten from scratch to wait
210          for printer status stabilization.
211       
212    - 1.20alpha11 :
213   
214        - Generic data dumper 'dumpykota' introduced.
215          Works only with PostgreSQL backend for now.
216         
217    - 1.20alpha10 :
218   
219        - Added fix for incorrect job's size computation when
220          hardware accounting fails.
221         
222    - 1.20alpha9 :
223   
224        - Small fixes wrt subprocesses.
225       
226    - 1.20alpha8 :
227   
228        - Added full support of PCL3 : HP Deskjet printers are now
229          supported.
230       
231    - 1.20alpha7 :
232   
233        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
234          Needs more work, but no documentation is available.
235       
236    - 1.20alpha6 :
237     
238        - Improved mailandpopup.sh script.
239       
240        - Small fixes for LPRng.
241       
242        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
243          hostname or IP address. Set to 'localhost' when not
244          meaningful.
245         
246        - Fixed issue with how mod_auth_ldap Apache modules
247          fills the REMOTE_USER environment variable.
248         
249        - Fixed a bug in LDAP user deletion code.
250       
251    - 1.20alpha5 :
252     
253        - Introduces the new configuration directive 'onaccountererror'
254          to specify what must be done whenever the software or
255          hardware accounter fails. Allowed values are 'continue' and
256          'stop' (default).
257         
258        - Minor fix in software accounter for a recently introduced
259          problem.
260         
261    - 1.20alpha4 :
262   
263        - Added support for more ghostscript devices in ESC/P2
264          analyzer : stcolor, st800, escp, escpc are now supported.
265         
266    - 1.20alpha3 :
267       
268        - Small improvement in PostScript parser to avoid being
269          fooled by a change in number of copies :
270          The user can't ask for 200 copies of page 1 and 1 copy
271          of page 2 to fool PyKota anymore :
272          this would have been accounted for as 1 copy only, but
273          now the maximum value seen is used.
274         
275        - Relax checks for PCL5 header to accomodate some strange
276          printer drivers.
277         
278        - Now hardware accounting method works like software
279          accounting method wrt the subprocess' output.
280         
281        - Hardware and Software accounting stop the print queue 
282          when the accounting subprocess didn't work. This will
283          be configurable in the near future.
284         
285    - 1.20alpha2 :
286   
287        - Now software accounting method reads accounter's
288          answer until a line with a single integer is
289          obtained or until all of its output has been read.
290          This should fix the problem some people have
291          when strange locale related messages are sent
292          when running subprocesses (Solaris only ?).
293         
294        - First version of ESC/P2 analyzer. Seems to work
295          ok at least with 'epson', 'epsonc', 'eps9mid'
296          and 'esp9high' ghostscript devices. Needs more
297          work to correctly analyze other devices.
298       
299    - 1.20alpha1 :
300   
301        - Fixed problem with number of copies in PCLXL parser.
302       
303        - Fixed problem with number of copies in PCL5 parser,
304          when number of copies was set outside of and before first
305          page.
306       
307        - Added workaround for number of copies directly set in
308          PostScript code.
309         
310        - Added german translation.
311       
312        - Fixed problem on first print for user group quota when
313          "enforcement: strict" is used.
314       
315        - Fixed interpolation problem in french translation.
316       
317    - 1.19 :
318   
319        - Updated existing translations.   
320       
321        - Added final Thai and Greek translations.
322       
323        - Minor last minute bug fixes.
324       
325    - 1.19beta :
326   
327        - LPRng support for both software and hardware accounting seems
328          to be OK.
329         
330        - Translation files fixed because of fuzzy matching problem. 
331       
332        - Fixed path to Swedish translation: 'sv' instead of 'se'.
333       
334        - Added first draft of Thai translation.
335       
336        - Fixed some minor bugs with Pychecker.
337       
338    - 1.19alpha35 :
339   
340        - Generic PDL analyzer now supports Binary PostScript documents
341          in addition to DSC compliant ones.
342       
343    - 1.19alpha34 :
344   
345        - LPRng support : software accounting seems to work fine,
346          but hardware accounting doesn't work yet.
347   
348    - 1.19alpha33 :
349   
350        - pykosd now accepts command line arguments. Enjoy !
351          NB : due to a bug in xosd, you need xosd version 2.2.8
352          or higher if you don't use the default C locale.
353         
354    - 1.19alpha32 :
355   
356        - Early (not working) version of the LPRng support rewrite.
357       
358        - Saner default configuration file.
359       
360    - 1.19alpha31 :
361   
362        - Fixed a double Python2.1 incompatibility with newer versions,
363          which prevented the PCL5 and the PCLXL parsers to work with
364          this older version of Python.
365         
366    - 1.19alpha30 :
367   
368        - Introduction of preliminary version of the pykosd command
369       
370        - Usernames, Groupnames and Printernames can now contain
371          ANY character, expected '/' and '@'.
372       
373        - Integrated most of the Debian work from Sergio
374          Gonz�z Gonz�z
375         
376    - 1.19alpha29 :
377   
378        - PCLXL parser should now correctly handle number of
379          copies set for each page.
380         
381        - Added testsuite for generic PDL analyzer.
382       
383        - Typo fixed in PCLXL parser.
384       
385        - Correctly dispatches error messages depending on the
386          situation : tools which can be run interactively will
387          ALWAYS output their logs to stderr, excepted for
388          their DEBUG messages, for which the "logger:"
389          directive as set in pykota.conf will be honored.
390          Tools which can't be run interactively will ALWAYS
391          honor the "logger:" directive as set in pykota.conf
392         
393    - 1.19alpha28 :
394   
395        - The description field for printers can now be set,
396          and is displayed in reports.
397         
398        - Fixed a small problem in SQL backend code.
399         
400        - Improved pkhint
401       
402        - First working PCL6 (aka PCLXL) parser !
403          Doesn't handle copies yet.
404       
405    - 1.19alpha27 :
406   
407        - Additionnal 10% speed increase in PCL5 parser for GhostScript
408          generated files (untested yet with other PCL files).
409         
410        - Reintroduced the use of mmap in PCL5 parser : this speedups
411          PCL5 parsing by almost 4 times.
412          This 4x with the 3x below give us in fact a twelvefold increase
413          in performance for PCL5 parsing !
414         
415        - The Python accelerator Psyco is now used if available
416          in the generic PDL parser : it speedups PCL5 parsing by
417          almost three times automagically.
418         
419    - 1.19alpha26 :
420   
421        - Fixed PCL5 parser according to the sources of rastertohp.
422       
423        - Fixed number of copies handling in PCL5 parser : the number
424          of copies could vary from page to page.
425         
426        - Added more debug information to PCLXL parser. 
427       
428    - 1.19alpha25 :
429   
430        - Added new "description" field to printers in both
431          PostgreSQL and LDAP. No code to handle this yet.
432         
433        - Reversed the fix for power save mode in printers : 
434          no paper or tray open would have caused people to
435          be undercharged.
436         
437        - Preliminary version of MySQL initialization script.
438         
439    - 1.19alpha24 :
440   
441        - Native PDF parsing code now works perfectly with
442          Python 2.1 and above, and is way faster than before.
443          GhostScript is not used anymore to convert PDF to PS,
444          because PDF is parsed directly.
445         
446    - 1.19alpha23 :
447   
448        - Fixed waitprinter.sh wrt PowerSave mode and some
449          printers. Thanks to Ryan Suarez.
450       
451        - Smart PDL analyzer now recognizes PDF too : two
452          PDF parsing methods are used : a native one which
453          is very fast but requires Python 2.3 or above, and
454          a slower one which uses Ghostscript. PyKota detects
455          automatically which method to use depending on your
456          version of Python.
457       
458        - All tracebacks now include PyKota's version number.
459         
460    - 1.19alpha22 :
461   
462        - Ensures that the file pointer for job's data is
463          reset to the start of the job's datas after the
464          job's size pre-computation phase.
465         
466        - Improved PostScript detection code for bad drivers
467          which don't correctly switch languages between PJL
468          and PS.
469       
470        - Even better debugging code.
471       
472    - 1.19alpha21 :
473   
474        - Additionnal check.
475       
476    - 1.19alpha20 :
477   
478        - More complete logging messages wrt accounters.
479       
480        - Now catches early failures occuring when the configuration
481          files are parsed.
482       
483    - 1.19alpha19 :
484   
485        - Fixed over-verbose exits when displaying help
486          or version.
487         
488        - Extended some PATH in the shell scripts 
489       
490        - Deleting an user now also deletes his payments history.
491       
492        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
493          cause problems.
494
495    - 1.19alpha18 :
496   
497        - History of payments is now stored in the database, and
498          updated each time an user's balance is modified with
499          edpykota --balance. This history represents each time
500          the user was given some positive or negative credit,
501          but doesn't reflect price paid for jobs, which appear
502          in the jobs history instead.
503         
504        - Jobs history web reports now include the job's size in
505          bytes. Also columns were reordered to render the report
506          more easily readable.
507         
508    - 1.19alpha17 :
509   
510        - Mysterious bug (program exited unexpectedly without leaving
511          any log message) which occured once in a while when
512          cancelling jobs should be fixed now.
513         
514        - New 'crashrecipient' directive. Disabled by 
515          default. See sample configuration file to see how
516          to activate it. It is suggested that you activate it.
517         
518        - New PYKOTAJOBSIZEBYTES environment variable exported, 
519          which contains the job's size in bytes. Empty jobs
520          are now denied. This value is now stored in the job
521          history (but not yet displayed from the web interface)
522         
523        - Preliminary work on payments storage : the PostgreSQL 
524          and LDAP schemas should be OK now, but no code is written
525          yet to support this functionnality.
526         
527    - 1.19alpha16 :
528   
529        - the newuser and newgroup LDAP specific directives now accept
530          a second parameter to attach(), "fail" or "warn". If no entry
531          is found to attach PyKota attributes to, and "fail" was used,
532          then action is aborted and program exits in error. If "warn"
533          is used, a new entry is created but a warning message is logged.
534         
535        - The job's originating hostname is now stored in the database,
536          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
537       
538    - 1.19alpha15 :
539   
540        - The old pykota filter is now removed. This means that
541          currently PyKota doesn't support LPRng anymore, but
542          LPRng support will be re-added, improved, in the near future.
543         
544    - 1.19alpha14 :
545   
546        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
547          are now exported as environment variables.
548         
549        - Heavy CPU usage is now completely fixed it seems, by
550          introducing some 0.01 second sleeping when nothing to do.
551         
552        - Pre-computation of the job's size is now only
553          done when enforcement is "STRICT", this saves
554          CPU for people who don't want to use this new
555          feature.
556         
557        - New 'enforcement' directive which accepts either
558          STRICT or LAXIST. See sample configuration file
559          for details.
560         
561    - 1.19alpha13 :
562   
563        - Get back to an old version of the polling loop which
564          worked fine, but non-optimally. Will be optimized
565          as time permits.
566         
567    - 1.19alpha12 :
568   
569        - Job's size is now precomputed unconditionnally using
570          the generic PDL analyzer.
571          NB : This value is not yet used to pre-allow/deny the
572          job.
573       
574    - 1.19alpha11 :
575   
576        - The pykota filter is now completely deprecated and
577          can't be used anymore. LPRng users MUST download
578          an older version of PyKota. CUPS users MUST use
579          cupspykota. Better support for LPRng will come
580          in the near future.
581         
582    - 1.19alpha10 :
583   
584        - pykotme now uses generic PDL Analyzer directly instead
585          of spawning a new process.
586         
587        - Improvements to generic PDL Analyzer.
588       
589        - 25% Speedup in PCL parser. Getting more of the Python version
590          will probably be difficult, since the completely table driven
591          parser I wrote is slower than the original algorithm. Then,
592          the original algorithm is still used for now.
593          Probable that more speed could be achieved using mmap, at the
594          expense of severe memory consumption.
595       
596        - configuration simplifications : the "accounter" directive's
597          'hardware' arguments now accepts what was in the "requester"
598          directive as it's content. The "requester" directive is not
599          supported anymore. See sample configuration file for details.
600       
601    - 1.19alpha9 :
602       
603        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
604       
605        - pykotaOptions LDAP attribute now accepts non-ascii characters
606          too.
607         
608        - First try at cupspykota main loop rewrite
609       
610    - 1.19alpha8 :
611   
612        - 'querying' accounting method is now called 'hardware'
613       
614        - 'external' accounting method is now called 'software'
615       
616        - 'stupid' accounting method doesn't exist anymore
617       
618        - 'snmp' requester doesn't exist anymore
619       
620        - code simplifications in external requester
621       
622    - 1.19alpha7 :
623     
624        - Database schema change (both LDAP and PostgreSQL) to
625          allow storage of the job-originating-hostname attribute.
626          An SQL upgrade script is present. The code is not yet
627          capable of setting/retrieving this attribute. Support
628          for this functionnality will be added in the future.
629         
630    - 1.19alpha6 :
631   
632        - problems connecting to SMTP servers are now catched.
633       
634        - pykotme now uses pkpgcounter to compute the size of the
635          job. This modification adds PCL5 and soon PCLXL (PCL6)
636          support. You can now get quotes for PCL in addition to
637          PostScript.
638         
639        - pkpgcounter now includes first try at PCLXL parser. 
640          It is currently disabled until it's finished.
641         
642    - 1.19alpha5 :
643   
644        - cupspykota polling loop fix for MacOSX (at least)
645       
646        - logging subsystem now logs PID too, to ease diagnosing
647          problems under heavy load.
648         
649        - pkpgcounter enhancements.
650       
651        - pkprinters --skipexisting now tells pkprinters to not
652          modify existing printers when --add is used.
653          pkprinters logs a warning message whenever --add is
654          used and a printer already exists.
655         
656        - LDAP schema now allows accented chars in pykotaFileName
657          and pykotaTitle attributes.
658       
659    - 1.19alpha4 :
660   
661        - a bad copy&paste prevented pkpgcounter to work at all, this
662          is now fixed.
663         
664        - improved PCL support in pkpgcounter, with the use of
665          HP PCL/PJL Reference Set
666          PCL5 Printer Language Technical Quick Reference Guide
667       
668        - pkpgcounter now uses mmap to speed things up : duration
669          is halved with the sample 87 pages PCL document I use for
670          testing.
671         
672    - 1.19alpha3 :
673   
674        - pkprinters now accepts the --list command line argument
675          to list informations about printers.
676         
677    - 1.19alpha2 :
678   
679        - pkpgcounter is now included as a smart external
680          accounter which can handle both PostScript and PCL.
681         
682    - 1.19alpha1 :
683   
684        - PYKOTALIMITBY environment variable is now exported too.
685       
686        - Inclusion of Michele Baldessari's work on autotools.
687       
688    - 1.18 :
689   
690        - Improved documentation
691       
692    - 1.18beta2 :
693     
694        - Fix for raw jobs with cupspykota
695       
696    - 1.18beta :
697   
698        - Small fix for new waitprinter.sh script
699       
700        - Better tracebacks on error conditions
701       
702        - Improved translations
703       
704        - Improved documentation
705       
706    - 1.18alpha15 :
707
708        - waitprinter.sh replaced by a new and possibly faster
709          and more powerful one.
710   
711        - Names can now begin with a digit.
712       
713        - Stability improvement for quotas set on printers groups.
714       
715    - 1.18alpha14 :
716   
717        - Catches more (all ?) problems with SMTP servers instead
718          of breaking.
719         
720        - Italian translation added.
721       
722    - 1.18alpha13 :
723   
724        - Pre and Post hooks are now available in the pykota
725          filter as well.
726         
727        - The pykota filter doesn't check last user's quota
728          anymore when delayed hardware accounting is used :
729          this will be done anyway the next time the last
730          user will print again. This saves some database
731          queries which are unneeded.
732       
733    - 1.18alpha12 :
734   
735        - Pre and Post hooks to external commands with many
736          many environment variables available are useable
737          from the cupspykota backend.
738          See sample configuration file for details and help.
739         
740    - 1.18alpha11 :
741   
742        - Hopefully final fix wrt groups (users and printers)
743       
744    - 1.18alpha10 :
745   
746        - Fixed nested printer groups accounting.
747       
748        - Fixed user groups + printer groups problem.
749       
750    - 1.18alpha9 :
751   
752        - Fix for LDAP problem when job price was 0.
753       
754        - Fix for empty user groups with LDAP.
755       
756        - Preliminary version of the snmpprinterstatus command added.
757       
758    - 1.18alpha8 :
759   
760        - Don't retrieve data when not needed.
761          This avoids many database queries.
762       
763    - 1.18alpha7 :
764   
765        - New experimental ldapcache directive to improve
766          LDAP caching.
767         
768    - 1.18alpha6 :
769       
770        - New configuration directive added : maildomain
771          to specify the domain to send mail to when user
772          email address is not set in PyKota database.
773         
774        - More complete email message headers. 
775         
776    - 1.18alpha5 :
777   
778        - Debian packaging specific files, contributed by
779          Peter Hawkins are now included in the project's tree.
780         
781        - Preliminary work on future low-level LDAP caching to speed
782          up modifications (at least).
783         
784    - 1.18alpha4 :
785   
786        - Applied some of the modifications suggested by
787          Peter Hawkins, for better Debian integration.
788          Most notably cupspykota, pykota, and the shell
789          scripts are now installed into /usr/share/pykota
790          instead of into /usr/bin
791          BEWARE : double check that your symbolic link
792          to cupspykota is correct, and that your pykota.conf
793          file use correct path for the shell scripts like
794          waitprinter.sh and al.
795         
796        - pkhint command added, to help in configuring correct
797          accounting method for PyKota.
798         
799    - 1.18alpha3 :
800   
801        - Fixed a rare bug in cupspykota backend which gave
802          incorrect "CUPS backend died abnormally" messages.
803       
804    - 1.18alpha2 :
805   
806        - Added the pkprinters command line tool to manage printers
807          exclusively.
808       
809    - 1.18alpha1 :
810   
811        - Preliminary work on Relationnal Database Independance.
812       
813        - Sample report made from OpenOffice.org added as PDF and SXC.
814

820   
821        - Fix stupid software accounting bug in the CUPS backend.
822       
823    - 1.17alpha1 :
824   
825        - User/Group deletion code in edpykota rewritten.
826       
827    - 1.16 :
828   
829        - Preliminary documentation on how to use OpenOffice.org
830          to create personnalized reports for PyKota + PostgreSQL.
831         
832        - Spanish installation guide for CUPS+PyKota+PostgreSQL
833          added to the documentation. Doesn't yet document v1.16
834          though.
835       
836        - Portuguese Portuguese translation replaces Brasilian
837          Portuguese Translation. Brasilian portuguese
838          translation is still available under the 'br' locale.
839       
840    - 1.16beta3 :
841   
842        - Swedish translation added.
843       
844        - Small fix in documentation.
845       
846    - 1.16beta2 :
847   
848        - Small fix for job cancelling code while job already
849          printing in CUPS backend.
850         
851        - Big fix wrt printing policies for unknown users. 
852       
853    - 1.16beta1 :
854   
855        - Manpages upgraded.
856       
857    - 1.16alpha26 :
858   
859        - Job price is now computed like this :
860       
861          SUM((NbPages * PricePerPage) + PricePerJob)
862         
863          For current printer and all the printers groups it is
864          a member of, if any.
865         
866          This may be difficult to grasp, but offers unprecedented
867          flexibility.
868         
869    - 1.16alpha25 :
870   
871        - Email address can be set at user creation time,
872          using the following syntax :
873         
874            $ edpykota --add username/email@yourdomain.com
875       
876    - 1.16alpha24 :
877   
878        - CGI script now can show the printing history.
879       
880        - Bug wrt number of copies should be fixed.
881       
882        - Major code refactoring => It is now possible to
883          automatically add printers on first print.
884       
885    - 1.16alpha23 :
886   
887        - Fixed potential accuracy problem if a user printed on
888          several printers at the very same time.
889       
890    - 1.16alpha22 :
891   
892        - edpykota now allows adding printers to printer groups
893       
894    - 1.16alpha21 :
895   
896        - Allows the dot in user and printer names.
897       
898        - Printer groups are now cached too.
899       
900    - 1.16alpha20 :
901   
902        - Fixed several small bugs with the help of PyChecker.
903       
904    - 1.16alpha19 :
905     
906        - Fixed a bug in PostgreSQL backend's code.
907       
908    - 1.16alpha18 :
909   
910        - Initial code for printer groups support. Printer groups have
911          to be added with external tools like psql or gq for example.
912          Printer groups seems to work fine with users. Untested with user
913          groups for now.
914
915        - Several minor visual problems fixed in reports.
916       
917        - Fixed a bug in LDAP date handling.
918       
919        - Fix for LDAP problem with some combination of OpenLDAP + Python-LDAP
920          + some particular settings.
921         
922        - mailandpopup.sh shell script added. See sample configuration file
923          for details.
924       
925        - Several environment variables are now exported when executing
926          external commands (accounters, requesters, mailers) :
927           
928            PYKOTAUSERNAME => user who is printing
929            PYKOTAPRINTERNAME => printer on which the job is being sent
930            PYKOTATITLE => Job's title
931            PYKOTAFILENAME => Job's filename
932            PYKOTACOPIES => number of copies asked
933            PYKOTAOPTIONS => print command options (-o with CUPS)
934         
935    - 1.16alpha17 :
936   
937        - Added portugues translation.
938       
939        - Major code refactoring in accounters.
940       
941    - 1.16alpha16 :
942   
943        - Code refactoring, and addition of a real HTML reporter, to
944          have nice looking and useful web based reports (in the future).
945       
946        - Added utolower configuration option to convert all usernames
947          to lowercase during printing.
948         
949    - 1.15alpha15 :
950   
951        - Now includes the papwaitprinter.sh shell script to wait for
952          AppleTalk enabled printers.
953         
954    - 1.16alpha14 :
955   
956        - Now printing on a printer not defined in the Quota Storage,
957          results in the job being cancelled or stopped, depending
958          on the printing system.
959         
960    - 1.16alpha13 :
961   
962        - Small bugfix wrt Python v2.1
963       
964        - If username is an empty string, user root is assumed.
965       
966        - 'postgresql' is not recognized anymore as a storage backend,
967          you have to use 'pgstorage' instead. 'postgresql' used to
968          be supported for compatibility with very old PyKota versions,
969          this is not the case anymore.
970         
971    - 1.16alpha12 :
972   
973        - Job price added to job history, to keep accounting correct
974          if a printer price per page or per job is modified and the
975          history is not reset : the history would have given a false
976          amount of money charged before the printer's prices were
977          modified, this addition solves the problem.
978         
979    - 1.16alpha11 :
980   
981        - Some preliminary modifications to the database structure for
982          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
983          database is now provided. LDAP attributes now support
984          eq, pres and sub indexes.
985         
986        - Job history now contains additional informations : 
987          number of copies, filename, title and print options.
988         
989    - 1.16alpha10 :
990       
991        - Some modifications done to external policy handling.
992          See sample configuration file for details.
993   
994        - Spanish translation added.
995       
996    - 1.16alpha9 :
997   
998        - mailto can be set to external(...) to warn users above
999          quota with any command of your choice (e.g. linpopup).
1000          Several parameters are available, see sample configuration
1001          file for details.
1002         
1003    - 1.16alpha8 :
1004   
1005        - Now cupspykota transmits SIGTERMS to the original 
1006          backend when the user deletes a job being processed.
1007         
1008        - The documentation is now licensed under the terms of the
1009          GNU GPL too.
1010         
1011    - 1.16alpha7 :
1012   
1013        - The CUPS backend is now fully functionnal (it seems).
1014       
1015        - From now on, the use of the pykota filter with CUPS
1016          is deprecated. The pykota filter still has to be
1017          used with LPRng though.
1018       
1019    - 1.16alpha6 :
1020   
1021        - Bug fixed : when edpykota was used to add a printer
1022          with no user or group name, a bad user/group name "*" was
1023          added to the database.
1024         
1025    - 1.16alpha5 :
1026   
1027        - New CUPS backend supports device enumeration !
1028          This means that NO manual CUPS configuration has to
1029          be done. All can now be done from CUPS web interface.
1030       
1031    - 1.16alpha4 :
1032   
1033        - New CUPS backend added.
1034       
1035    - 1.16alpha3 :
1036       
1037        - Minimal FAQ document added.
1038       
1039    - 1.16alpha2 :
1040   
1041        - CGI script now partially supports browser's language preference
1042       
1043    - 1.16alpha1 :
1044   
1045        - Ensures that the LDAP connection is really closed at end.
1046       
1047        - More complete error messages in case of LDAP operation failure.
1048       
1049    - 1.15 :
1050     
1051        - Documentation improved.
1052       
1053    - 1.15beta :
1054   
1055        - Command line tools now accept multiple printer
1056          names or wildcards, separated with commas.
1057         
1058    - 1.15alpha9 :
1059   
1060        - External policy can be used to auto-add unknown users
1061          and any other interesting things you may want to do.
1062          WARNING : You can't auto-add printers for now.
1063          They have to be created manually before.
1064          Look at sample configuration file for examples.
1065         
1066    - 1.15alpha8 :
1067   
1068        - Job history can be disabled if needed.
1069          This feature may be useful for people who use the LDAP
1070          backend and don't want their LDAP tree to grow out of
1071          control.
1072       
1073    - 1.15alpha7 :
1074   
1075        - More work done on caching wrt groups.
1076       
1077    - 1.15alpha6 :
1078   
1079        - Performance bottleneck with LDAP solved.
1080       
1081    - 1.15alpha5 :
1082   
1083        - Caching mechanism for all database queries.
1084
1085    - 1.15alpha4 :
1086   
1087        - Problem with Python 2.3 fixed. Needs some definitive
1088          modification.
1089         
1090    - 1.15alpha3 :
1091   
1092        - CGI script now tries to restrict view when the
1093          REMOTE_USER environment variable is set. This allows
1094          people to protect its use with .htaccess files.
1095          When unprotected, or if REMOTE_USER is 'root', then
1096          unrestricted access is granted.
1097          NB : REMOTE_USER is automatically set by the web server
1098          (e.g. Apache) when a page with restricted access is viewed.
1099         
1100    - 1.15alpha2 :
1101   
1102        - Better detection of LPRng.
1103       
1104        - Outputs a warning if printing system is unknown.
1105       
1106    - 1.15alpha1 :
1107   
1108        - Bug fix in SQL code.
1109       
1110    - 1.14 :
1111   
1112        - The PostgreSQL database connection is now always closed before
1113          exit. The LDAP database connection too, but it didn't suffer
1114          from the problem anyway, AFAICT.
1115       
1116    - 1.14beta2 :
1117   
1118        - An LDAP-specific configuration field was introduced, usermail.
1119          Use it to specify which LDAP attribute contains a valid email
1120          address for the user. See sample configuration file for
1121          details.
1122       
1123    - 1.14beta :
1124   
1125        - Two new LDAP-specific configuration fields were introduced,
1126          newuser and newgroup. Use them to specify if you want to add
1127          quota information to existing entries or elsewhere.
1128          See sample configuration file for details.
1129         
1130    - 1.14alpha9 :
1131   
1132        - Documentation improved.
1133       
1134        - pykotme now also prints the user's account balance value
1135          if the user is registered in the Quota Storage and his
1136          limiting factor is "balance".
1137         
1138    - 1.14alpha8 :
1139   
1140        - bin/waitprinter.sh is now included to wait for
1141          SNMP enabled printers to be idle again before
1142          asking for their internal page counter.
1143          See sample configuration file for details.
1144         
1145    - 1.14alpha7 :
1146   
1147        - edpykota now doesn't check if the user/group is above
1148          quota. The check is only done at print time. This
1149          prevents the sending of email messages when creating
1150          user quotas if quota is already reached at creation
1151          time.
1152         
1153    - 1.14alpha6 :
1154   
1155        - Configuration file split and moved to /etc/pykota/pykota.conf
1156          and /etc/pykota/pykotadmin.conf to prevent simple users to
1157          have Read/Write access to the Quota Database.
1158          Don't forget to :
1159         
1160                $ chmod 640 /etc/pykota/pykotadmin.conf
1161               
1162        - storageuser and storageuserpw configuration fields reintroduced
1163          for the same reason.
1164         
1165        - Code cleaning for future implementation of email addresses
1166          support in the PostgreSQL and LDAP backends.
1167         
1168    - 1.14alpha5 :
1169       
1170        - Big bug fixed when changing the prices for a printer
1171       
1172    - 1.14alpha4 :
1173   
1174        - When adding an user, the user itself and its account balance
1175          are now added in the same LDAP entry. Before they were added
1176          as two different LDAP entries.
1177         
1178    - 1.14alpha3 :
1179   
1180        - Email field added to PostgreSQL database. An upgrade script
1181          is included in initscripts/postgresql.
1182       
1183    - 1.14alpha2 :
1184   
1185        - Typo fixed when using the --prototype option to edpykota
1186       
1187    - 1.14alpha1 :
1188   
1189        - Poor man's treshold included : users with a low account
1190          balance (below 1.0 by default, configurable) are sent
1191          a warning message.
1192         
1193        - All warning messages to users are now configurable. 
1194          NB : Warning messages to the administrator are not.
1195       
1196    - 1.13 :
1197   
1198        - Some small fixes wrt group handling.
1199       
1200        - The whole module code was passed through PyChecker and
1201          several small code inconsistencies were fixed,
1202          as well as a bug in the groups code.
1203         
1204    - 1.13alpha1 :
1205   
1206        - Bug fix wrt LDAP.
1207       
1208    - 1.12 :
1209   
1210        - More complete test added in edpykota.
1211       
1212    - 1.12alpha2 :
1213   
1214        - The previous bug fix was incomplete. This is corrected.
1215       
1216    - 1.12alpha1 :
1217   
1218        - Small bug fix.
1219       
1220    - 1.11 :
1221   
1222        - Now includes the pykotme command line tool, to produce
1223          printing quotes for users.
1224         
1225    - 1.10 :
1226   
1227        - Bug fixed wrt quota reports when print limiting is by
1228          account balance.
1229         
1230    - 1.09 :
1231   
1232        - Translations finalized.
1233       
1234        - Manpages updated.
1235       
1236        - Installation documentation improved wrt LDAP support.
1237       
1238    - 1.09beta2 :
1239   
1240        - The CGI script for quota reports works again, and
1241          is much more powerful.
1242       
1243    - 1.09beta :
1244   
1245        - edpykota finalized
1246       
1247    - 1.09alpha2 :
1248   
1249        - LDAP schema modified a bit. Please upgrade.
1250       
1251        - LDAP backend works !
1252       
1253        - repykota and warnpykota allow the root user to pass
1254          users or groups names on the command line. Users
1255          and groups names may contain wildcards.
1256         
1257        - repykota and warnpykota only reports or warns the
1258          current user when launched by non-root users.
1259         
1260        - Minor bug fixes. 
1261   
1262    - 1.09alpha1 :
1263   
1264        - More work on LDAP storage backend. Many options
1265          were added to /etc/pykota.conf to give some
1266          hints to the LDAP storage backend.
1267         
1268        - Severe database access optimizations were done by
1269          rewriting most of the Quota Storage backends drivers.
1270     
1271    - 1.08 :
1272   
1273        - Major bug fix wrt LPRng support for remote jobs.
1274       
1275        - Major bug fix wrt increase/decrease account balances.
1276       
1277    - 1.08alpha8 :
1278   
1279        - Code refactoring.
1280       
1281        - A single user/password pair is used to connect
1282          to the database backend. The storageuser configuration
1283          field, and its associated passwords storageuserpw, are
1284          not used anymore.
1285         
1286        - You can now set PyKota in debug mode, see sample configuration 
1287          file for details.
1288          WARNING : only Quota Storage backend queries are logged in
1289          debug mode, for now.
1290       
1291    - 1.08alpha7 :
1292   
1293        - Very latest LDAP schema.
1294       
1295        - Code enhancement wrt easy pluggability of PyKota attributes
1296          and object classes into an existing LDAP directory.
1297       
1298    - 1.08alpha6 :
1299   
1300        - Minor bug corrections
1301       
1302        - More work on LDAP : new schema
1303       
1304    - 1.08alpha5 :
1305   
1306        - More good work on LDAP storage.
1307          repykota now works reasonably well with the sample LDAP directory.
1308       
1309    - 1.08alpha4 :
1310   
1311        - LDAP schema included.
1312          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
1313          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1314          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1315          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1316          MAILING LIST.
1317         
1318    - 1.08alpha3 :
1319   
1320        - External accounting methods were partly rewritten :
1321         
1322          - No more "broken pipe" should happen.
1323         
1324          - They now take care of the number of copies
1325            This may be unneeded though, if the postscript
1326            file already does this, because this would
1327            overcharge users (number of copies counted
1328            two times). NEEDS MORE TESTING.
1329           
1330          - The sample configuration file now contains 
1331            an external accounting method example which should
1332            work with all DSC compliant Postscript files.
1333           
1334        - Some small bugs were fixed.   
1335       
1336    - 1.08alpha2 :
1337   
1338        - Now works with net-snmp v5.0 and above.
1339          It already worked, but the sample configuration
1340          file didn't contain appropriate values...
1341       
1342    - 1.07 : Release of the Shame !
1343   
1344        - The external accounting methods driver was left out of
1345          the CVS tree. Nobody could use it since it wasn't included !
1346         
1347    - 1.06 :
1348   
1349        - Severe bug fixed : if you had a printer in
1350          power saving state which couldn't answer immediately,
1351          a bug was triggered.
1352          It was caused by a bad copy/paste which
1353          forgot to import a Python module at run time.
1354         
1355    - 1.05 :
1356   
1357        - External accounters are finally available !
1358          This means that you can plug any page accounting
1359          method you like by setting the appropriate
1360          'accounter' field in /etc/pykota.conf
1361          See the sample conf/pykota.conf.sample to
1362          learn how to do.
1363         
1364          NB : Both 'external' and 'stupid' accounting methods
1365               account a job size just before *this* job is
1366               sent to the printer.
1367               The original 'querying' method accounts a job
1368               size just before *the next* job is sent to
1369               the printer.
1370       
1371    - 1.05alpha3 :
1372   
1373        - A 'stupid' and unreliable accounting method was
1374          implemented to serve as an example on how to
1375          do this sort of things. This method only counts
1376          the 'showpage' statements in the input data.
1377          See sample configuration file for details.
1378          Pluggable accounting methods work, but I advise
1379          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1380          It is not reliable enough to be used.
1381          Use the 'querying' accounting method instead.
1382         
1383    - 1.05alpha2 :
1384   
1385        - Pluggable accounting methods.
1386       
1387        - Better error handling.
1388       
1389    - 1.05alpha1 :
1390   
1391        - SECURITY file added to help improve PyKota's security.
1392       
1393        - Extracting the printer's internal page counter is now
1394          tried several times, waiting several seconds between
1395          two tries. This lets the time to warm up for some printers
1396          which don't answer when they are sleeping (my Apple
1397          LaserWriter 16/600 PS is in this case, maybe others too)
1398         
1399        - Small display bug fixed in repykota
1400         
1401    - 1.04 :
1402   
1403        - Default print policy for users/groups unknown from
1404          the print quota system is now DENY instead of ALLOW,
1405          since ALLOW can generate inaccurate results
1406          (incorrect job sizes charged to the wrong persons)
1407         
1408        - LPRng support works !
1409       
1410        - A bug was introduced some time ago wrt printers' default
1411          policy for unknown users. It is now corrected.
1412       
1413        - repykota now displays prices per job and per page for each
1414          printer, if they are defined.
1415         
1416        - Minor display bug fixed in repykota.
1417       
1418        - Problem when running repykota with an empty database was fixed.
1419       
1420    - 1.03 :
1421   
1422        - Upgrade script included for earlier versions.
1423          Please look inside the initscripts subdirectory.
1424          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1425         
1426        - repykota now reports account balances too.
1427       
1428        - PyKota now has a nice logo, see the logos
1429          subdirectory.
1430       
1431        - Manual pages were finally updated.
1432       
1433        - Group quotas seem to work now !
1434       
1435        - The new database schema allows to keep an history of all
1436          jobs as well as charge users per page and/or per job,
1437          and track users' account balance.
1438         
1439        - edpykota now accepts much more command line options to 
1440          use the new functionnalities. See edpykota --help for
1441          details.
1442         
1443        - The installation script now allows to install the sample
1444          configuration file during first installation.
1445         
1446        - More group quota code works, but still not finished. 
1447       
1448        - The CGI script displays a link to PyKota's website.
1449       
1450        - The job history is now kept, this will allow per-period
1451          reports in the future.
1452         
1453        - After having modified the quota for an user with edpykota,
1454          a quota check is done to eventually warn the user/admin about
1455          a quota which is too low to print.
1456         
1457        - A workaround is provided for HP Printers : their internal
1458          page counter is only saved to NVRAM in a 10 increment, so
1459          if you switch them off and then on, the reported page counter
1460          may be lower than the real number of pages printed.
1461          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1462          We unconditionnally set the last job's page count to
1463          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1464          in this case.
1465          For a more accurate accounting, never switch your HP printers
1466          off.
1467         
1468        - A fix is provided for printers which only have a volatile 
1469          page counter (reset to 0 every time you switch the printer on)
1470          This should allow PyKota to work reasonably fine with HP Laserjet
1471          4L/5L/6L, not perfect, but better than nothing.
1472          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1473          For a more accurate accounting, never switch your HP printers
1474          off. This is untested, please report any problem.
1475         
1476        - A bug was fixed when edpykota --add was used with users who already
1477          had a quota on the specified printer.
1478         
1479        - A small display bug in repykota was introduced in preliminary
1480          1.03 versions, and fixed later on.
1481         
1482        - Some minor bugs which happened in rare situations were fixed.
1483

1488          print quota or by account balance.
1489       
1490    - 1.02 :
1491   
1492        - The installation script now checks for software availability
1493          and in case a software is missing asks the user if he
1494          wants to continue with the installation or abort it.
1495         
1496        - The configuration file pykota.conf is now expected to be
1497          found in /etc instead of in /etc/cups
1498          The installation script prompts the user to see if he
1499          wants to move an old configuration file to the new location

1502        - Improved documentation.
1503       
1504        - You can now set the tcp/ip port on which the Quota Storage

1515          to choose the recipient(s) of the email messages :
1516         
1517            - DevNull means no one will receive them.
1518            - User means only the user will receive them.
1519            - Admin means only the admin will receive them.
1520            - Both means the User and the Admin will receive them.

1537          disable quota checking while still doing page

1548   
1549        - Under some circumstances while the user wasn't allowed
1550          to print, he didn't receive any email message. It is

1553        - When an user wasn't allowed to print, the quota for
1554          the previous user wasn't updated. This is now fixed.

1565          if the --add option is not set, e.g. :
1566         
1567              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1568             
1569        - If no user name is passed at all, then a default wildcard of "*"
1570          which means apply the command on ALL users for this printer is used.
1571         
1572        - Small bug fixes.
1573       
1574    - 0.96 :
1575
1576        - Options requester, policy, admin, adminmail and gracedelay can now

1580        - More powerful configuration parser.
1581       
1582        - If all options are defined globally, there's no need to
1583          define a section for each printer in the configuration
1584          file anymore. Just define a [global] section and it's ok.
1585
1586    - 0.95 :
1587
1588        - External requesters for printers finally added.
