23       
24    - 1.25alpha17 (2006-11-27) :
25   
26        - pkrefund can now create receipts in the PDF format.
27       
28        - The code was changed to accomodate ReportLab 2.x in pkbanner
29          and pkinvoice. ReportLab v1.x is now only supported with
30          an english or C locale.
31         
32        - pknotify now accepts the --noremote command line option to
33          decide what has to be done when there's no PyKotIcon running
34          or accepting connections from the print server on the client host.
35         
36        - pkprinters now only modifies CUPS' printers.conf when the
37          -C | --cups command line switch is used.
38         
39    - 1.25alpha16 (2006-11-12) :

49    - 1.25alpha15 (2006-11-06) :   
50   
51        - pkprinters --add and --delete now automatically reroutes CUPS
52          print queues through PyKota or through CUPS only.
53         
54        - Fixed date and time parsing problems.
55       
56        - Finally simplified the locking code again, and checked that no
57          stalled lock can persist. The lock files remain on disk though,
58          but it is a small price to pay.
59         
60    - 1.25alpha14 (2006-10-13) :
61     
62        - Removed some locking code which would have prevented multi-server
63          configuration to work correctly with a shared lock directory.
64         
65        - First useable release with the computation of ink
66          usage, through the introduction of the 'ink(cspace, resolution)'
67          value for the 'preaccounter' and 'accounter' directives in
68          pykota.conf
69         
70    - 1.25alpha13 (2006-10-04) :
71     
72        - The dumpykota.cgi script now does basic form checking
73          to immediately avoid incompatible dump options and
74          alerts the end user if Javascript is enabled.
75         
76        - The filter keys in dumpykota can now be specified in
77          lower or upper case.
78         
79        - Introduced the 'noprintingmaxdelay' directive to workaround
80          some buggy printers when hardware accounting is used.
81         
82        - Improved the reliability of hardware accounting. 
83         
84    - 1.25alpha12 (2006-09-15) :

89    - 1.25alpha11 (2006-09-06) :
90   
91        - Now fails in an helpful manner if python-mysqldb is too old.
92       
93        - Now exports the original username and billing code (i.e.
94          their values before they are eventually overwritten) in
95          two additionnal environment variables.
96         
97    - 1.25alpha10 (2006-09-03) :
98   
99        - Rewrote the locking mechanism to try to fix the problem
100          some people reported.
101         
102        - Permissions on cupspykota are now correctly set after
103          installation.
104         
105        - Added a workaround to incorrect charset through the add
106          of the python-chardet module as a dependency.
107         
108    - 1.25alpha9 (2006-08-10) :
109   
110        - Fixed a problem when an SMTP error occured and the recovery
111          routine failed to handle it correctly.
112         
113    - 1.25alpha8 (2006-07-11) :
114

125   
126        - pkusers now supports the --email command line switch.
127          The old method to set the email address is still supported,
128          but the new one allows the email address to be modified
129          as well.
130         
131    - 1.25alpha6 (2006-06-09) :

142    - 1.25alpha4 (2006-05-23) :
143   
144        - Introduced the 'askconfirmation' directive to interact with
145          the end user through any script (pknotify is recommended)
146          and see if he really wants to print when knowing the cost
147          of the job.
148         
149        - Now uses pkipplib if present to directly retrieve the job
150          information from the CUPS server over IPP.
151         
152    - 1.25alpha3 (2006-05-11) :
153   
154        - Added a lock to ensure that a single cupspykota backend
155          is processing datas for a particular print queue at any
156          given time.
157         
158        - Now exports more environment variables for the subprocesses.

170        - Fixed several character encoding problems.
171         
172        - Ensures that the denied banners counter is properly initialized
173          with relationnal databases.
174         
175    - 1.24 (2006-04-08) :
176   
177        - Improved documentation and packaging stuff.
178       
179    - 1.24beta (2006-03-26) :
180   
181        - Finalized the pknotify command.
182       
183        - Updated the messages catalogs for translations.
184       
185    - 1.24alpha18 (2006-03-15) :
186   
187        - Now uses MIME encapsulation for email messages to avoid
188          some problems with 8 bits messages being rejected.

199          with remote PyKotIcon applications.
200         
201    - 1.24alpha15 (2006-03-02) :
202       
203        - optimized pkbcodes, pkprinters and pkusers using edpykota as
204          the model.
205       
206        - 'edpykota --list' and 'pkusers --list' are now authorized
207          to mere mortal users, but the list is restricted to informations
208          about the current user.
209       
210        - Extended the functionnality of the 'onbackenderror' directive to
211          allow for configurable retries.
212         
213    - 1.24alpha14 :
214   
215        - Finished optimizations in edpykota and fixed some minor
216          problems with LDAP.
217         
218    - 1.24alpha13 :
219   
220        - Introduced the pkusers command line tool to manage users and 
221          users groups. This command doesn't deal with print quota entries,
222          which continue to be managed through the edpykota command line
223          tool.
224         
225        - Major rewrite and incompatible changes to command line options
226          in edpykota. This command now only deals with print quota
227          entries. Printers, users (or users groups) now have to be created
228          first using pkprinters or pkusers.
229         
230    - 1.24alpha12 :
231   
232        - Introduced the 'duplicatesdelay' directive to specify after
233          which duration two duplicate jobs are not considered duplicate
234          jobs anymore.
235         
236        - Introduced the 'balancezero' directive to specify any value 
237          as the balance limit instead of 0.0. This can allow admins to
238          give a few free credits to users, for example.
239         
240    - 1.24alpha11 :
241   
242        - Huge speed improvements when modifying billing codes and
243          printers.
244       
245        - Both pkbcodes and pkprinters now display the percent done
246          for all actions.
247         
248        - The pkinvoice invoice generator command line utility is now
249          included.
250         
251    - 1.24alpha10 :   
252   
253        - Huge speed improvements when deleting users, printers, and
254          billing codes.
255         
256    - 1.24alpha9 :
257   
258        - Preliminary support for MySQL, thanks to Matt Hyclak.
259       
260    - 1.24alpha8 :
261   
262        - The 'preaccounter' configuration directive was introduced to control
263          which parser to use for precomputation of the job's size. When unset,
264          the internal parser is used just like it was previously. See
265          conf/pykota.conf.sample for more details.
266         
267        - Now subprocesses launched through the overwrite_jobticket directive
268          can also output 'CANCEL', to represent the user's own choice to
269          cancel the print job.
270         
271    - 1.24alpha7 :
272     
273        - pkbanner now handles new print limiting modes correctly.
274       
275        - The cupspykota backend wrapper now accepts to be interrupted
276          with a kill -INT. This causes an immediate and clean abort
277          of the current print job.
278         
279        - Matt Hyclak contributed the possibility to store the printing
280          history in a MySQL database. See the contributed/ directory
281          for details.
282         
283        - Added 2006 to the copyright's years.
284       
285    - 1.24alpha6 :
286   
287        - Fixed internal SNMP and PJL handling code for very fast
288          printers : PyKota didn't see them going from 'idle'
289          to 'printing' to 'idle' again.
290         
291        - Now waitprinter.sh accepts SNMP version number and
292          community name as arguments, thanks to Brandon
293          Holbrook.
294         
295        - Now command line errors and Ctrl+C repectively cause
296          PyKota commands to exit with status -2 and -3.
297         
298    - 1.24alpha5 :
299   
300        - All command line tools now accept -A | --arguments filename.args
301          as a way to bypass the shell's maximal command line size :
302          just put each argument on a line by itself in a file, and
303          pass the file's name as the -A | --arguments command line
304          option's argument. For now this won't be documented in
305          commands' helps.
306         
307        - dumpykota can now dump the complete database in XML
308          format.
309         
310    - 1.24alpha4 :
311   
312        - Added support for the SQLite3 backend.
313          See pykota/initscripts/sqlite/README.sqlite
314       
315    - 1.24alpha3 :
316   
317        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
318          so we regain priviledges before running an external
319          mailto directive.
320       
321    - 1.24alpha2 :
322   
323        - Introduce the "onbackenderror" directive in pykota.conf, to
324          control if the user must be charged or not whenever a real
325          CUPS backend fails. The default value is 'nocharge'.
326          Set it to 'charge' if you think your users can cause a CUPS
327          backend to fail.
328         
329        - Now mark original backends related problems as such in the
330          printing history. Modified printquota.cgi and pykota.css
331          to make them be more visible.
332         
333    - 1.24alpha1 :
334   
335        - Fixed a problem which caused backend errors to be ignored.
336       
337        - The sample LDIF file now contains the two necessary user
338          entries to have an LDAP PyKota Admin and an LDAP PyKota
339          ReadOnly user. The sample configuration files were updated
340          to contain the default passwords used in the LDIF file.
341         
342        - dumpykota is now more strict when checking arguments.   
343       
344    - 1.23 :
345   
346        - Many minor bug fixes and code cleaning.
347       
348        - Improved documentation.
349       
350        - Added Polish translation.
351       
352        - Improved French and Swedish translations.
353       
354    - 1.23beta :
355   
356        - Now the mailto directive is honored in all cases where the job is
357          denied or a warning has to be issued, and the correct reason
358          can be sent back to the user.
359         
360        - The PYKOTAREASON environment variable, if defined, contains the 
361          textual reason why the job was denied or a warning has to be
362          issued.
363       
364    - 1.23alpha31 :
365   
366        - Added support for --maxjobsize, --passthrough and --nopassthrough
367          in pkprinters. These modes are now also honored when printing.
368         
369        - Allows the admin to restrict the number of print queues which will
370          be treated by pkturnkey by passing queues' names as additionnal
371          arguments on pkturnkey's command line.
372         
373        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
374          command line option.   
375         
376    - 1.23alpha30 :
377   
378        - Database changes : you MUST use upgrade-to-1.23.sql again if you
379          use PostgreSQL, or copy the new schema and restart your LDAP
380          server if you use LDAP.
381         
382        - The -C | --comment command line switch was added to edpykota to 
383          attach textual information to modifications done to a user's
384          account balance.
385         
386        - The -l | --limitby command line switch to edpykota was modified 
387          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
388          command's help or manual page for details.
389         
390        - The -i | --ingroups command line switch to repykota allows 
391          PyKota Administrators to only lists members of the specified
392          group or groups (separated with commas).
393         
394        - The -I | --increase command line switch to edpykota allows
395          to increase or decrease page limits.
396         
397        - Added the precomputed job's size and price to the history
398          for controlling purpose.
399       
400    - 1.23alpha29 :
401   
402        - Fixed a small problem with billing codes.
403       
404        - Exports some environment variables earlier, to render the script
405          launched by the overwrite_jobticket directive more powerful.
406         
407        - Now autopykota also creates print quota entries for the user on the
408          printers groups the current printer is a member of.
409         
410    - 1.23alpha28 :
411   
412        - Added users groups management to pkturnkey.
413       
414        - Fixed umask in setup script.
415       
416    - 1.23alpha27 :
417   
418        - Replaced the --dryrun command line option by the --force
419          command line option in pkturnkey, with exactly the opposite
420          effect (for security reasons).
421         
422    - 1.23alpha26 :
423   
424        - Allows parametrized pjl and snmp hardware accounting methods,
425          to be able to respectively set the TCP port and the SNMP
426          community.
427         
428    - 1.23alpha25 :
429   
430        - Added a --dryrun command line switch to pkturnkey.
431       
432        - Improved pkturnkey's general usability.
433       
434        - Added a manpage for pkturnkey.
435       
436    - 1.23alpha24 :
437   
438        - Allows different databases to be used depending on the
439          user's rights. This allows PyKota admins to directly
440          use a master LDAP server for read+write, while letting
441          normal users using the replicas for readonly access.
442          NB : using different storage backends is also possible,
443          but you're on your own there.
444         
445    - 1.23alpha23 :
446   
447        - Fixed a problem with banner accounting.

454          It's now much more readable, maintainable, etc...
455         
456        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
457          advised to download earlier releases or purchase the
458          PyKota v1.22HotFix1 Official release. LPRng support
459          MIGHT be re-added later.
460       
461    - 1.23alpha21 :
462     
463        - Fix for IPP requests which contain more than a single
464          job-originating-host-name attribute.
465         
466    - 1.23alpha20 :
467   
468        - Added the overwrite_jobticket directive. See pykota.conf.sample
469          for how to use it.
470         
471    - 1.23alpha19 :
472   
473        - Fixed an LDAP filtering problem when managing billing codes.
474       
475        - Added the unknown_billingcode directive. See pykota.conf.sample
476          for how to use it.
477       
478    - 1.23alpha18 :
479     
480        - Added the dump_bfd.php contribution.
481       
482        - Several fixes in the internal PJL accounter.
483       
484        - Now autopykota doesn't create unneeded print quota entries anymore.
485       
486        - Increased the timeout in the PJL hardware accounting code to
487          accomodate some printers (HP5000 at least).
488         
489    - 1.23alpha17 :
490   
491        - pkpgcounter is now distributed separately only. This
492          means that people must now download and install pkpgcounter
493          v1.56 or higher prior to being able to run PyKota.
494         
495        - Removed all the autoconf/automake stuff which was outdated 
496          and confusing.
497         
498    - 1.23alpha16 :
499     
500        - Extracted the GPL blurb from all commands' help, and use
501          a static version only once. This saves space big time, and
502          eases future translations.
503         
504    - 1.23alpha15 :
505   
506        - pkbcodes now works with the PostgreSQL backend.

508       
509    - 1.23alpha14 :
510

523   
524        - Small fix to the PCL3/4/5 parser for some drivers.
525       
526    - 1.23alpha10 :
527   
528        - Fixed a bad exception name in cupspykota when parsing IPP messages.
529       
530        - Improved the IPP messages module : it can now generate IPP messages
531          in addition to parsing them.
532       
533    - 1.23alpha9 :   
534   
535        - The denyduplicates directive now accepts a command line as an
536          argument beside yes/no. The command is launched and must
537          print either ALLOW or DENY to its standard output. Then the
538          job gets allowed or denied by PyKota.
539          This will allow user interaction in the near future.
540         
541        - Introduced the new 'striptitle' directive to remove ugly prefixes
542          from print job's titles whenever a new print job is submitted.
543         
544        - Fixed internal SNMP accounter for printers which only have a life time
545          page counter, and not a volatile page counter.
546         
547    - 1.23alpha8 :
548   
549        - The data dumper can now summarize payments and history with the
550          help of the --sum command line option (or checkbox in the CGI).
551         
552        - The message used when the job's filename, title and options are
553          hidden because of the privacy directive is now translated at
554          retrieval time, instead of at saving time.
555         
556        - Minor fix in the LDAP backend code. 
557         
558    - 1.23alpha7 :
559   
560        - Improvements to the internal PJL and SNMP accounter : now should
561          support more printers and waste less time.
562         
563    - 1.23alpha6 :
564   
565        - The data dumper's start= and end= date filtering options now
566          accept a positive or negative offset to be added to the special
567          keywords 'yesterday', 'today', 'now', 'tomorrow'.
568          e.g. : dumpykota --data history start=yesterday-5 end=today
569         
570    - 1.23alpha5 :
571   
572        - The data dumper's start= and end= date filtering options now accept
573          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
574         
575    - 1.23alpha4 :
576   
577        - The data dumper now accept start= and end= to specify the starting
578          and ending dates to dump the history.
579         
580    - 1.23alpha3 :
581   
582        - The destination link for the logo used in CGI scripts is
583          configurable.
584         
585        - Data dumper improved : it's faster and now datas are correctly
586          escaped.
587       
588        - The URL to the logo displayed in the CGI scripts is configurable.
589       
590    - 1.23alpha2 :
591   
592        - Fixed edpykota --prototype with balance.
593

596       
597    - 1.23alpha1 :   
598   
599        - Sets current username to the user CUPS runs as instead of "root"
600          when printing test pages from CUPS' web interface (because
601          the username is empty in this case).
602         
603        - Fix for strange values in job-originating-hostname
604       
605    - 1.22 :
606

663   
664        - Fixes some case related problems with some LDAP backends.
665       
666        - Fixes some problem for printers which directly go from
667          "idle" to "warmup" and never to "printing" before
668          returning to "idle".
669         
670        - Some permissions settings may have prevented cupspykota
671          from parsing cupsd.conf, this is now fixed.
672

674   
675        - Introduction of the web enabled print quote generator.
676

708    - 1.21alpha27 :
709   
710        - Allows software() (no arguments) to the software accounting
711          directive. This saves a lot of CPU since the job is not
712          parsed again : the precomputed size is used directly in this
713          case.
714         
715        - epykota's --prototype option now works fine with accounts
716          limited by balance.

729          'enforcement' is not set to 'strict'.
730         
731        - Introduction of the new 'trustjobsize' configuration directive
732          to workaround some problematic printers. See the sample
733          configuration file for details.
734         
735    - 1.21alpha24 :
736   
737        - Big database structure changes. An upgrade script
738          is now included for PostgreSQL. LDAP users may just
739          want to copy the new schema in place.
740         
741        - edpykota now recognizes the -o | --overcharge command line
742          option to set an overcharging or undercharging factor
743          on each print job's cost for a particular user.
744         
745        - repykota's output format has changed an is not limited to 
746          80 characters wide anymore. People who used to parse
747          repykota's output in their own tools are strongly advised
748          to parse dumpykota's output instead.
749         
750        - Introduction of the new 'maxdenybanners' configuration directive
751          to allow up to N (the directive's value) deny banners to be
752          printed even if the print account is forbidden to print.
753         
754        - Better detection of the number of copies in the PostScript parser.
755

761       
762    - 1.21alpha22 :
763   
764        - edpykota's --delete command line option doesn't consider
765          '*' to be the default argument anymore :-)
766         
767    - 1.21alpha21 :
768   
769        - dumpykota.cgi can now be run as a normal user as opposed to
770          a PyKota administrator. No read access to pykotadmin.conf is
771          necessary anymore. This CGI scripts now honors the REMOTE_USER
772          environment variable just like printquota.cgi does, see
773          the file cgi-bin/README for details.
774          The command line tool dumpykota must still be run by a PyKota
775          administrator.
776         
777        - Fix exception's name error due to a change in recent versions
778          of PygreSQL.

782        - Big bug fix wrt the datelimit field which was never reset.
783         
784    - 1.21alpha19 :
785   
786        - Introduction of the new dumpykota.cgi CGI script, which
787          allows third party tools like phpPrintAnalyzer to be
788          interfaced in real time with PyKota. To use it you
789          may have to change your web server's configuration,
790          please see pykota/cgi-bin/README
791         
792    - 1.21alpha18 :
793   
794        - Now dumpykota can dump the job history into CUPS' page_log
795          format (even when the printing system is LPRng). This allows
796          people to use tools like PrintAnalyzer or phpPrintAnalyzer
797          (two completely different beasts) with PyKota.
798         
799    - 1.21alpha17 :
800     
801        - Fixed field type's name in XML dumps.
802       
803        - Now drops priviledges to user 'pykota' when launched as root
804          (directly or as a CUPS backend), if such an user exists.

818        - dumpykota filtering capabilities are now supported within
819          the LDAP backend too.
820         
821    - 1.21alpha14 :
822   
823        - dumpykota now supports extended filtering possibilities
824          with the PostgreSQL backend (LDAP support will come soon).
825         
826    - 1.21alpha13 :
827   
828        - Added a --debug command line option to pkpgcounter, so
829          that people may see what really happens, and what will
830          be available in the future :-)
831         
832    - 1.21alpha12 :
833   
834        - Fixed a bug with non standard pkbanner command lines.
835       
836        - Now logs as errors the differences between precomputed and
837          computed job sizes. **CUPS only for now**
838         
839    - 1.21alpha11 :
840   
841        - Now user and group print quota entries can be stored directly
842          below the user or group with the LDAP backend, using them
843          as branches. Thanks to Stefan Wold for the patch.
844          See the sample configuration file for details.
845         
846        - TLS is now supported with the LDAP backend. Thanks to Stefan
847          Wold for the patch.
848          See the sample configuration file for details.
849         
850        - edpkota now accepts the -U | --used value command line argument
851          to preset the page counters to an initial value. Thanks to
852          Wilson Roberto Afonso and Matt Hyclak for the patch.
853         
854    - 1.21alpha10 :
855   
856        - Now automatically reconnects up to three times if the LDAP server
857          returned an error, possibly due to a timeout.
858         
859    - 1.21alpha9 :
860   
861        - Now searches the configuration files in 'pykota' system user's
862          home directory. The 'pykota' system user and group have
863          to be created by the system administrator, and given
864          sufficient permissions to PyKota's configuration files.
865         
866    - 1.21alpha8 :
867

909    - 1.21alpha1 :
910   
911        - added an IPP messages miniparser. Extraction of the client
912          hostname is now considered to be fiable, at least until
913          the CUPS developpers change something...
914       
915    - 1.20 :
916   
917        - Version number changed.

978       
979        - edpykota now refuse to work if the user is not a PyKota admin.
980       
981        - Fixes a recently introduced bug with users groups and PostgreSQL.
982       
983    - 1.20alpha21 :
984   
985        - Now dumpykota refuses to launch if the current user is not
986          a PyKota administrator (a PyKota administrator is an user
987          allowed to read the pykotadmin.conf file).
988         
989        - Now any PyKota administrator can use repykota and warnpykota
990          with additionnal arguments, not only the root user.
991         
992        - Improved documentation a bit.
993       
994    - 1.20alpha20 :
995   
996        - Reduced delay in internal SNMP and PJL_over_TCP handlers
997          from 2 to 1 second.
998       
999        - dumpykota can now output XML.
1000       
1001    - 1.20alpha19 :
1002   
1003        - Improved user groups and user groups quotas dumps in dumpykota.
1004       
1005        - Finished implementation of LDAP support in dumpykota.
1006       
1007        - The md5 sum of the job's datas is now available as an
1008          hexadecimal digest in the PYKOTAMD5SUM environment variable.
1009         
1010        - The description, filename, title, and options fields
1011          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
1012          Proper charset is used during extraction from the database.
1013         
1014    - 1.20alpha18 :
1015   
1016        - Experimental autopykota command to initialize user
1017          account and quota entries on first print while not
1018          resetting the balance value if not needed.
1019         
1020        - Added the new "winbind_separator" directive to strip
1021          out the Samba/Winbind domain name while printing if
1022          needed (Off by default).
1023         
1024    - 1.20alpha17 :
1025   
1026        - Added --hardreset command line option to edpykota.
1027       
1028        - Fixed problem with accented chars in title, filename
1029          or options and LDAP backend.
1030         
1031    - 1.20alpha16 :
1032   
1033        - Internal handling of socket based PJL queries over
1034          port tcp/9100 is now available with the magic
1035          'pjl' value in the hardware accounter.
1036         
1037    - 1.20alpha15 :
1038   
1039        - LDAP pykotaAccountBalance objects were always created
1040          attached to the pykotaUser objects. This is now
1041          fixed and the value of balancebase in pykota.conf
1042          is now correctly used.
1043         
1044    - 1.20alpha14 :
1045   
1046        - Belgian translations added (copy of the french ones).
1047       
1048        - External hardware accounter now loops until
1049          a result can be read correctly.
1050         
1051        - pkhint now suggest the internal snmp handling instead
1052          of the external one.
1053         
1054    - 1.20alpha13 :
1055     
1056        - Hardware accounter now accepts the special
1057          'snmp' value, meaning ALL is done from main code
1058          without launching any subprocess.
1059          You need the http://pysnmp.sf.net Python module
1060          for this to work (tested with v3.4.2)
1061         
1062        - Increased delay between two loops iterations 
1063          to 2 seconds in waitprinter.sh to diminish
1064          CPU load.
1065         
1066    - 1.20alpha12 :
1067   
1068        - waitprinter.sh rewritten from scratch to wait
1069          for printer status stabilization.
1070       
1071    - 1.20alpha11 :
1072   
1073        - Generic data dumper 'dumpykota' introduced.
1074          Works only with PostgreSQL backend for now.
1075         
1076    - 1.20alpha10 :
1077   
1078        - Added fix for incorrect job's size computation when
1079          hardware accounting fails.
1080         
1081    - 1.20alpha9 :
1082   
1083        - Small fixes wrt subprocesses.
1084       
1085    - 1.20alpha8 :
1086   
1087        - Added full support of PCL3 : HP Deskjet printers are now
1088          supported.
1089       
1090    - 1.20alpha7 :
1091   
1092        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
1093          Needs more work, but no documentation is available.
1094       
1095    - 1.20alpha6 :
1096     
1097        - Improved mailandpopup.sh script.
1098       
1099        - Small fixes for LPRng.
1100       
1101        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
1102          hostname or IP address. Set to 'localhost' when not
1103          meaningful.
1104         
1105        - Fixed issue with how mod_auth_ldap Apache modules
1106          fills the REMOTE_USER environment variable.
1107         
1108        - Fixed a bug in LDAP user deletion code.
1109       
1110    - 1.20alpha5 :
1111     
1112        - Introduces the new configuration directive 'onaccountererror'
1113          to specify what must be done whenever the software or
1114          hardware accounter fails. Allowed values are 'continue' and
1115          'stop' (default).
1116         
1117        - Minor fix in software accounter for a recently introduced
1118          problem.
1119         
1120    - 1.20alpha4 :
1121   
1122        - Added support for more ghostscript devices in ESC/P2
1123          analyzer : stcolor, st800, escp, escpc are now supported.
1124         
1125    - 1.20alpha3 :
1126       
1127        - Small improvement in PostScript parser to avoid being
1128          fooled by a change in number of copies :
1129          The user can't ask for 200 copies of page 1 and 1 copy
1130          of page 2 to fool PyKota anymore :
1131          this would have been accounted for as 1 copy only, but
1132          now the maximum value seen is used.
1133         
1134        - Relax checks for PCL5 header to accomodate some strange
1135          printer drivers.
1136         
1137        - Now hardware accounting method works like software
1138          accounting method wrt the subprocess' output.
1139         
1140        - Hardware and Software accounting stop the print queue 
1141          when the accounting subprocess didn't work. This will
1142          be configurable in the near future.
1143         
1144    - 1.20alpha2 :
1145   
1146        - Now software accounting method reads accounter's
1147          answer until a line with a single integer is
1148          obtained or until all of its output has been read.
1149          This should fix the problem some people have
1150          when strange locale related messages are sent
1151          when running subprocesses (Solaris only ?).
1152         
1153        - First version of ESC/P2 analyzer. Seems to work
1154          ok at least with 'epson', 'epsonc', 'eps9mid'
1155          and 'esp9high' ghostscript devices. Needs more
1156          work to correctly analyze other devices.
1157       
1158    - 1.20alpha1 :
1159   
1160        - Fixed problem with number of copies in PCLXL parser.
1161       
1162        - Fixed problem with number of copies in PCL5 parser,
1163          when number of copies was set outside of and before first
1164          page.
1165       
1166        - Added workaround for number of copies directly set in
1167          PostScript code.
1168         
1169        - Added german translation.
1170       
1171        - Fixed problem on first print for user group quota when
1172          "enforcement: strict" is used.
1173       
1174        - Fixed interpolation problem in french translation.
1175       
1176    - 1.19 :
1177   
1178        - Updated existing translations.   
1179       
1180        - Added final Thai and Greek translations.
1181       
1182        - Minor last minute bug fixes.
1183       
1184    - 1.19beta :
1185   
1186        - LPRng support for both software and hardware accounting seems
1187          to be OK.
1188         
1189        - Translation files fixed because of fuzzy matching problem. 
1190       
1191        - Fixed path to Swedish translation: 'sv' instead of 'se'.
1192       
1193        - Added first draft of Thai translation.
1194       
1195        - Fixed some minor bugs with Pychecker.
1196       
1197    - 1.19alpha35 :
1198   
1199        - Generic PDL analyzer now supports Binary PostScript documents
1200          in addition to DSC compliant ones.
1201       
1202    - 1.19alpha34 :
1203   
1204        - LPRng support : software accounting seems to work fine,
1205          but hardware accounting doesn't work yet.
1206   
1207    - 1.19alpha33 :
1208   
1209        - pykosd now accepts command line arguments. Enjoy !
1210          NB : due to a bug in xosd, you need xosd version 2.2.8
1211          or higher if you don't use the default C locale.
1212         
1213    - 1.19alpha32 :
1214   
1215        - Early (not working) version of the LPRng support rewrite.
1216       
1217        - Saner default configuration file.
1218       
1219    - 1.19alpha31 :
1220   
1221        - Fixed a double Python2.1 incompatibility with newer versions,
1222          which prevented the PCL5 and the PCLXL parsers to work with
1223          this older version of Python.
1224         
1225    - 1.19alpha30 :
1226   
1227        - Introduction of preliminary version of the pykosd command
1228       
1229        - Usernames, Groupnames and Printernames can now contain
1230          ANY character, expected '/' and '@'.
1231       
1232        - Integrated most of the Debian work from Sergio
1233          Gonz�z Gonz�z
1234         
1235    - 1.19alpha29 :
1236   
1237        - PCLXL parser should now correctly handle number of
1238          copies set for each page.
1239         
1240        - Added testsuite for generic PDL analyzer.
1241       
1242        - Typo fixed in PCLXL parser.
1243       
1244        - Correctly dispatches error messages depending on the
1245          situation : tools which can be run interactively will
1246          ALWAYS output their logs to stderr, excepted for
1247          their DEBUG messages, for which the "logger:"
1248          directive as set in pykota.conf will be honored.
1249          Tools which can't be run interactively will ALWAYS
1250          honor the "logger:" directive as set in pykota.conf
1251         
1252    - 1.19alpha28 :
1253   
1254        - The description field for printers can now be set,
1255          and is displayed in reports.
1256         
1257        - Fixed a small problem in SQL backend code.
1258         
1259        - Improved pkhint
1260       
1261        - First working PCL6 (aka PCLXL) parser !
1262          Doesn't handle copies yet.
1263       
1264    - 1.19alpha27 :
1265   
1266        - Additionnal 10% speed increase in PCL5 parser for GhostScript
1267          generated files (untested yet with other PCL files).
1268         
1269        - Reintroduced the use of mmap in PCL5 parser : this speedups
1270          PCL5 parsing by almost 4 times.
1271          This 4x with the 3x below give us in fact a twelvefold increase
1272          in performance for PCL5 parsing !
1273         
1274        - The Python accelerator Psyco is now used if available
1275          in the generic PDL parser : it speedups PCL5 parsing by
1276          almost three times automagically.
1277         
1278    - 1.19alpha26 :
1279   
1280        - Fixed PCL5 parser according to the sources of rastertohp.
1281       
1282        - Fixed number of copies handling in PCL5 parser : the number
1283          of copies could vary from page to page.
1284         
1285        - Added more debug information to PCLXL parser. 
1286       
1287    - 1.19alpha25 :
1288   
1289        - Added new "description" field to printers in both
1290          PostgreSQL and LDAP. No code to handle this yet.
1291         
1292        - Reversed the fix for power save mode in printers : 
1293          no paper or tray open would have caused people to
1294          be undercharged.
1295         
1296        - Preliminary version of MySQL initialization script.
1297         
1298    - 1.19alpha24 :
1299   
1300        - Native PDF parsing code now works perfectly with
1301          Python 2.1 and above, and is way faster than before.
1302          GhostScript is not used anymore to convert PDF to PS,
1303          because PDF is parsed directly.
1304         
1305    - 1.19alpha23 :
1306   
1307        - Fixed waitprinter.sh wrt PowerSave mode and some
1308          printers. Thanks to Ryan Suarez.
1309       
1310        - Smart PDL analyzer now recognizes PDF too : two
1311          PDF parsing methods are used : a native one which
1312          is very fast but requires Python 2.3 or above, and
1313          a slower one which uses Ghostscript. PyKota detects
1314          automatically which method to use depending on your
1315          version of Python.
1316       
1317        - All tracebacks now include PyKota's version number.
1318         
1319    - 1.19alpha22 :
1320   
1321        - Ensures that the file pointer for job's data is
1322          reset to the start of the job's datas after the
1323          job's size pre-computation phase.
1324         
1325        - Improved PostScript detection code for bad drivers
1326          which don't correctly switch languages between PJL
1327          and PS.
1328       
1329        - Even better debugging code.
1330       
1331    - 1.19alpha21 :
1332   
1333        - Additionnal check.
1334       
1335    - 1.19alpha20 :
1336   
1337        - More complete logging messages wrt accounters.
1338       
1339        - Now catches early failures occuring when the configuration
1340          files are parsed.
1341       
1342    - 1.19alpha19 :
1343   
1344        - Fixed over-verbose exits when displaying help
1345          or version.
1346         
1347        - Extended some PATH in the shell scripts 
1348       
1349        - Deleting an user now also deletes his payments history.
1350       
1351        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
1352          cause problems.
1353
1354    - 1.19alpha18 :
1355   
1356        - History of payments is now stored in the database, and
1357          updated each time an user's balance is modified with
1358          edpykota --balance. This history represents each time
1359          the user was given some positive or negative credit,
1360          but doesn't reflect price paid for jobs, which appear
1361          in the jobs history instead.
1362         
1363        - Jobs history web reports now include the job's size in
1364          bytes. Also columns were reordered to render the report
1365          more easily readable.
1366         
1367    - 1.19alpha17 :
1368   
1369        - Mysterious bug (program exited unexpectedly without leaving
1370          any log message) which occured once in a while when
1371          cancelling jobs should be fixed now.
1372         
1373        - New 'crashrecipient' directive. Disabled by 
1374          default. See sample configuration file to see how
1375          to activate it. It is suggested that you activate it.
1376         
1377        - New PYKOTAJOBSIZEBYTES environment variable exported, 
1378          which contains the job's size in bytes. Empty jobs
1379          are now denied. This value is now stored in the job
1380          history (but not yet displayed from the web interface)
1381         
1382        - Preliminary work on payments storage : the PostgreSQL 
1383          and LDAP schemas should be OK now, but no code is written
1384          yet to support this functionnality.
1385         
1386    - 1.19alpha16 :
1387   
1388        - the newuser and newgroup LDAP specific directives now accept
1389          a second parameter to attach(), "fail" or "warn". If no entry
1390          is found to attach PyKota attributes to, and "fail" was used,
1391          then action is aborted and program exits in error. If "warn"
1392          is used, a new entry is created but a warning message is logged.
1393         
1394        - The job's originating hostname is now stored in the database,
1395          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
1396       
1397    - 1.19alpha15 :
1398   
1399        - The old pykota filter is now removed. This means that
1400          currently PyKota doesn't support LPRng anymore, but
1401          LPRng support will be re-added, improved, in the near future.
1402         
1403    - 1.19alpha14 :
1404   
1405        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
1406          are now exported as environment variables.
1407         
1408        - Heavy CPU usage is now completely fixed it seems, by
1409          introducing some 0.01 second sleeping when nothing to do.
1410         
1411        - Pre-computation of the job's size is now only
1412          done when enforcement is "STRICT", this saves
1413          CPU for people who don't want to use this new
1414          feature.
1415         
1416        - New 'enforcement' directive which accepts either
1417          STRICT or LAXIST. See sample configuration file
1418          for details.
1419         
1420    - 1.19alpha13 :
1421   
1422        - Get back to an old version of the polling loop which
1423          worked fine, but non-optimally. Will be optimized
1424          as time permits.
1425         
1426    - 1.19alpha12 :
1427   
1428        - Job's size is now precomputed unconditionnally using
1429          the generic PDL analyzer.
1430          NB : This value is not yet used to pre-allow/deny the
1431          job.
1432       
1433    - 1.19alpha11 :
1434   
1435        - The pykota filter is now completely deprecated and
1436          can't be used anymore. LPRng users MUST download
1437          an older version of PyKota. CUPS users MUST use
1438          cupspykota. Better support for LPRng will come
1439          in the near future.
1440         
1441    - 1.19alpha10 :
1442   
1443        - pykotme now uses generic PDL Analyzer directly instead
1444          of spawning a new process.
1445         
1446        - Improvements to generic PDL Analyzer.
1447       
1448        - 25% Speedup in PCL parser. Getting more of the Python version
1449          will probably be difficult, since the completely table driven
1450          parser I wrote is slower than the original algorithm. Then,
1451          the original algorithm is still used for now.
1452          Probable that more speed could be achieved using mmap, at the
1453          expense of severe memory consumption.
1454       
1455        - configuration simplifications : the "accounter" directive's
1456          'hardware' arguments now accepts what was in the "requester"
1457          directive as it's content. The "requester" directive is not
1458          supported anymore. See sample configuration file for details.
1459       
1460    - 1.19alpha9 :
1461       
1462        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1463       
1464        - pykotaOptions LDAP attribute now accepts non-ascii characters
1465          too.
1466         
1467        - First try at cupspykota main loop rewrite
1468       
1469    - 1.19alpha8 :
1470   
1471        - 'querying' accounting method is now called 'hardware'
1472       
1473        - 'external' accounting method is now called 'software'
1474       
1475        - 'stupid' accounting method doesn't exist anymore
1476       
1477        - 'snmp' requester doesn't exist anymore
1478       
1479        - code simplifications in external requester
1480       
1481    - 1.19alpha7 :
1482     
1483        - Database schema change (both LDAP and PostgreSQL) to
1484          allow storage of the job-originating-hostname attribute.
1485          An SQL upgrade script is present. The code is not yet
1486          capable of setting/retrieving this attribute. Support
1487          for this functionnality will be added in the future.
1488         
1489    - 1.19alpha6 :
1490   
1491        - problems connecting to SMTP servers are now catched.
1492       
1493        - pykotme now uses pkpgcounter to compute the size of the
1494          job. This modification adds PCL5 and soon PCLXL (PCL6)
1495          support. You can now get quotes for PCL in addition to
1496          PostScript.
1497         
1498        - pkpgcounter now includes first try at PCLXL parser. 
1499          It is currently disabled until it's finished.
1500         
1501    - 1.19alpha5 :
1502   
1503        - cupspykota polling loop fix for MacOSX (at least)
1504       
1505        - logging subsystem now logs PID too, to ease diagnosing
1506          problems under heavy load.
1507         
1508        - pkpgcounter enhancements.
1509       
1510        - pkprinters --skipexisting now tells pkprinters to not
1511          modify existing printers when --add is used.
1512          pkprinters logs a warning message whenever --add is
1513          used and a printer already exists.
1514         
1515        - LDAP schema now allows accented chars in pykotaFileName
1516          and pykotaTitle attributes.
1517       
1518    - 1.19alpha4 :
1519   
1520        - a bad copy&paste prevented pkpgcounter to work at all, this
1521          is now fixed.
1522         
1523        - improved PCL support in pkpgcounter, with the use of
1524          HP PCL/PJL Reference Set
1525          PCL5 Printer Language Technical Quick Reference Guide
1526       
1527        - pkpgcounter now uses mmap to speed things up : duration
1528          is halved with the sample 87 pages PCL document I use for
1529          testing.
1530         
1531    - 1.19alpha3 :
1532   
1533        - pkprinters now accepts the --list command line argument
1534          to list informations about printers.
1535         
1536    - 1.19alpha2 :
1537   
1538        - pkpgcounter is now included as a smart external
1539          accounter which can handle both PostScript and PCL.
1540         
1541    - 1.19alpha1 :
1542   
1543        - PYKOTALIMITBY environment variable is now exported too.
1544       
1545        - Inclusion of Michele Baldessari's work on autotools.
1546       
1547    - 1.18 :
1548

1558       
1559        - Better tracebacks on error conditions
1560       
1561        - Improved translations
1562       
1563        - Improved documentation
1564       
1565    - 1.18alpha15 :
1566
1567        - waitprinter.sh replaced by a new and possibly faster
1568          and more powerful one.
1569   
1570        - Names can now begin with a digit.
1571       
1572        - Stability improvement for quotas set on printers groups.
1573       
1574    - 1.18alpha14 :
1575   
1576        - Catches more (all ?) problems with SMTP servers instead
1577          of breaking.
1578         
1579        - Italian translation added.
1580       
1581    - 1.18alpha13 :
1582   
1583        - Pre and Post hooks are now available in the pykota
1584          filter as well.
1585         
1586        - The pykota filter doesn't check last user's quota
1587          anymore when delayed hardware accounting is used :
1588          this will be done anyway the next time the last
1589          user will print again. This saves some database
1590          queries which are unneeded.
1591       
1592    - 1.18alpha12 :
1593   
1594        - Pre and Post hooks to external commands with many
1595          many environment variables available are useable
1596          from the cupspykota backend.
1597          See sample configuration file for details and help.
1598         
1599    - 1.18alpha11 :
1600   
1601        - Hopefully final fix wrt groups (users and printers)
1602       
1603    - 1.18alpha10 :
1604   
1605        - Fixed nested printer groups accounting.
1606       
1607        - Fixed user groups + printer groups problem.
1608       
1609    - 1.18alpha9 :

1612       
1613        - Fix for empty user groups with LDAP.
1614       
1615        - Preliminary version of the snmpprinterstatus command added.
1616       
1617    - 1.18alpha8 :
1618

1623   
1624        - New experimental ldapcache directive to improve
1625          LDAP caching.

1634         
1635    - 1.18alpha5 :
1636   
1637        - Debian packaging specific files, contributed by
1638          Peter Hawkins are now included in the project's tree.
1639         
1640        - Preliminary work on future low-level LDAP caching to speed
1641          up modifications (at least).
1642         
1643    - 1.18alpha4 :
1644   
1645        - Applied some of the modifications suggested by
1646          Peter Hawkins, for better Debian integration.
1647          Most notably cupspykota, pykota, and the shell
1648          scripts are now installed into /usr/share/pykota
1649          instead of into /usr/bin
1650          BEWARE : double check that your symbolic link
1651          to cupspykota is correct, and that your pykota.conf
1652          file use correct path for the shell scripts like
1653          waitprinter.sh and al.
1654         
1655        - pkhint command added, to help in configuring correct
1656          accounting method for PyKota.

1692          added to the documentation. Doesn't yet document v1.16
1693          though.
1694       
1695        - Portuguese Portuguese translation replaces Brazilian
1696          Portuguese Translation. Brazilian portuguese
1697          translation is still available under the 'br' locale.
1698       
1699    - 1.16beta3 :
1700

1705    - 1.16beta2 :
1706   
1707        - Small fix for job cancelling code while job already
1708          printing in CUPS backend.
1709         
1710        - Big fix wrt printing policies for unknown users. 
1711       
1712    - 1.16beta1 :
1713   
1714        - Manpages upgraded.
1715       
1716    - 1.16alpha26 :
1717   
1718        - Job price is now computed like this :
1719       
1720          SUM((NbPages * PricePerPage) + PricePerJob)
1721         
1722          For current printer and all the printers groups it is
1723          a member of, if any.
1724         
1725          This may be difficult to grasp, but offers unprecedented
1726          flexibility.
1727         
1728    - 1.16alpha25 :

1743       
1744    - 1.16alpha23 :
1745   
1746        - Fixed potential accuracy problem if a user printed on

1766       
1767    - 1.16alpha18 :
1768

1770          to be added with external tools like psql or gq for example.
1771          Printer groups seems to work fine with users. Untested with user
1772          groups for now.
1773
1774        - Several minor visual problems fixed in reports.
1775       
1776        - Fixed a bug in LDAP date handling.
1777       
1778        - Fix for LDAP problem with some combination of OpenLDAP + Python-LDAP
1779          + some particular settings.
1780         
1781        - mailandpopup.sh shell script added. See sample configuration file
1782          for details.
1783       
1784        - Several environment variables are now exported when executing
1785          external commands (accounters, requesters, mailers) :
1786           
1787            PYKOTAUSERNAME => user who is printing
1788            PYKOTAPRINTERNAME => printer on which the job is being sent
1789            PYKOTATITLE => Job's title
1790            PYKOTAFILENAME => Job's filename
1791            PYKOTACOPIES => number of copies asked
1792            PYKOTAOPTIONS => print command options (-o with CUPS)

1805        - Added utolower configuration option to convert all usernames
1806          to lowercase during printing.
1807         
1808    - 1.15alpha15 :
1809   
1810        - Now includes the papwaitprinter.sh shell script to wait for
1811          AppleTalk enabled printers.
1812         
1813    - 1.16alpha14 :
1814   
1815        - Now printing on a printer not defined in the Quota Storage,
1816          results in the job being cancelled or stopped, depending
1817          on the printing system.
1818         
1819    - 1.16alpha13 :
1820   
1821        - Small bugfix wrt Python v2.1
1822       
1823        - If username is an empty string, user root is assumed.
1824       
1825        - 'postgresql' is not recognized anymore as a storage backend,
1826          you have to use 'pgstorage' instead. 'postgresql' used to
1827          be supported for compatibility with very old PyKota versions,
1828          this is not the case anymore.
1829         
1830    - 1.16alpha12 :
1831   
1832        - Job price added to job history, to keep accounting correct
1833          if a printer price per page or per job is modified and the
1834          history is not reset : the history would have given a false
1835          amount of money charged before the printer's prices were
1836          modified, this addition solves the problem.
1837         
1838    - 1.16alpha11 :
1839   
1840        - Some preliminary modifications to the database structure for
1841          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1842          database is now provided. LDAP attributes now support
1843          eq, pres and sub indexes.
1844         
1845        - Job history now contains additional informations : 
1846          number of copies, filename, title and print options.
1847         
1848    - 1.16alpha10 :
1849       
1850        - Some modifications done to external policy handling.
1851          See sample configuration file for details.
1852   
1853        - Spanish translation added.
1854       
1855    - 1.16alpha9 :
1856   
1857        - mailto can be set to external(...) to warn users above
1858          quota with any command of your choice (e.g. linpopup).
1859          Several parameters are available, see sample configuration
1860          file for details.
1861         
1862    - 1.16alpha8 :
1863   
1864        - Now cupspykota transmits SIGTERMS to the original 
1865          backend when the user deletes a job being processed.

1872        - The CUPS backend is now fully functionnal (it seems).
1873       
1874        - From now on, the use of the pykota filter with CUPS
1875          is deprecated. The pykota filter still has to be
1876          used with LPRng though.
1877       
1878    - 1.16alpha6 :
1879   
1880        - Bug fixed : when edpykota was used to add a printer
1881          with no user or group name, a bad user/group name "*" was
1882          added to the database.
1883         
1884    - 1.16alpha5 :
1885   
1886        - New CUPS backend supports device enumeration !
1887          This means that NO manual CUPS configuration has to
1888          be done. All can now be done from CUPS web interface.
1889       
1890    - 1.16alpha4 :
1891   
1892        - New CUPS backend added.

1914        - Command line tools now accept multiple printer
1915          names or wildcards, separated with commas.
1916         
1917    - 1.15alpha9 :
1918   
1919        - External policy can be used to auto-add unknown users
1920          and any other interesting things you may want to do.
1921          WARNING : You can't auto-add printers for now.
1922          They have to be created manually before.
1923          Look at sample configuration file for examples.
1924         
1925    - 1.15alpha8 :
1926   
1927        - Job history can be disabled if needed.
1928          This feature may be useful for people who use the LDAP
1929          backend and don't want their LDAP tree to grow out of
1930          control.
1931       
1932    - 1.15alpha7 :
1933   
1934        - More work done on caching wrt groups.
1935       
1936    - 1.15alpha6 :
1937   
1938        - Performance bottleneck with LDAP solved.
1939       
1940    - 1.15alpha5 :
1941   
1942        - Caching mechanism for all database queries.
1943
1944    - 1.15alpha4 :
1945   
1946        - Problem with Python 2.3 fixed. Needs some definitive
1947          modification.
1948         
1949    - 1.15alpha3 :
1950   
1951        - CGI script now tries to restrict view when the
1952          REMOTE_USER environment variable is set. This allows
1953          people to protect its use with .htaccess files.
1954          When unprotected, or if REMOTE_USER is 'root', then
1955          unrestricted access is granted.
1956          NB : REMOTE_USER is automatically set by the web server
1957          (e.g. Apache) when a page with restricted access is viewed.
1958         
1959    - 1.15alpha2 :
1960   
1961        - Better detection of LPRng.
1962       
1963        - Outputs a warning if printing system is unknown.
1964       
1965    - 1.15alpha1 :
1966   
1967        - Bug fix in SQL code.
1968       
1969    - 1.14 :
1970   
1971        - The PostgreSQL database connection is now always closed before
1972          exit. The LDAP database connection too, but it didn't suffer
1973          from the problem anyway, AFAICT.
1974       
1975    - 1.14beta2 :
1976   
1977        - An LDAP-specific configuration field was introduced, usermail.
1978          Use it to specify which LDAP attribute contains a valid email
1979          address for the user. See sample configuration file for
1980          details.
1981       
1982    - 1.14beta :
1983   
1984        - Two new LDAP-specific configuration fields were introduced,
1985          newuser and newgroup. Use them to specify if you want to add
1986          quota information to existing entries or elsewhere.
1987          See sample configuration file for details.
1988         
1989    - 1.14alpha9 :
1990   
1991        - Documentation improved.
1992       
1993        - pykotme now also prints the user's account balance value
1994          if the user is registered in the Quota Storage and his
1995          limiting factor is "balance".
1996         
1997    - 1.14alpha8 :
1998   
1999        - bin/waitprinter.sh is now included to wait for
2000          SNMP enabled printers to be idle again before
2001          asking for their internal page counter.
2002          See sample configuration file for details.
2003         
2004    - 1.14alpha7 :
2005   
2006        - edpykota now doesn't check if the user/group is above
2007          quota. The check is only done at print time. This
2008          prevents the sending of email messages when creating
2009          user quotas if quota is already reached at creation
2010          time.
2011         
2012    - 1.14alpha6 :
2013   
2014        - Configuration file split and moved to /etc/pykota/pykota.conf
2015          and /etc/pykota/pykotadmin.conf to prevent simple users to
2016          have Read/Write access to the Quota Database.
2017          Don't forget to :
2018         
2019                $ chmod 640 /etc/pykota/pykotadmin.conf
2020               
2021        - storageuser and storageuserpw configuration fields reintroduced
2022          for the same reason.
2023         
2024        - Code cleaning for future implementation of email addresses
2025          support in the PostgreSQL and LDAP backends.
2026         
2027    - 1.14alpha5 :
2028       
2029        - Big bug fixed when changing the prices for a printer
2030       
2031    - 1.14alpha4 :
2032   
2033        - When adding an user, the user itself and its account balance
2034          are now added in the same LDAP entry. Before they were added
2035          as two different LDAP entries.
2036         
2037    - 1.14alpha3 :
2038   
2039        - Email field added to PostgreSQL database. An upgrade script
2040          is included in initscripts/postgresql.
2041       
2042    - 1.14alpha2 :
2043   
2044        - Typo fixed when using the --prototype option to edpykota
2045       
2046    - 1.14alpha1 :
2047   
2048        - Poor man's treshold included : users with a low account
2049          balance (below 1.0 by default, configurable) are sent
2050          a warning message.
2051         
2052        - All warning messages to users are now configurable. 
2053          NB : Warning messages to the administrator are not.
2054       
2055    - 1.13 :
2056   
2057        - Some small fixes wrt group handling.
2058       
2059        - The whole module code was passed through PyChecker and
2060          several small code inconsistencies were fixed,
2061          as well as a bug in the groups code.
2062         
2063    - 1.13alpha1 :
2064   
2065        - Bug fix wrt LDAP.
2066       
2067    - 1.12 :
2068   
2069        - More complete test added in edpykota.
2070       
2071    - 1.12alpha2 :
2072   
2073        - The previous bug fix was incomplete. This is corrected.
2074       
2075    - 1.12alpha1 :
2076   
2077        - Small bug fix.
2078       
2079    - 1.11 :
2080   
2081        - Now includes the pykotme command line tool, to produce
2082          printing quotes for users.
2083         
2084    - 1.10 :
2085   
2086        - Bug fixed wrt quota reports when print limiting is by
2087          account balance.
2088         
2089    - 1.09 :
2090   
2091        - Translations finalized.
2092       
2093        - Manpages updated.
2094       
2095        - Installation documentation improved wrt LDAP support.
2096       
2097    - 1.09beta2 :
2098   
2099        - The CGI script for quota reports works again, and
2100          is much more powerful.
2101       
2102    - 1.09beta :
2103   
2104        - edpykota finalized
2105       
2106    - 1.09alpha2 :
2107   
2108        - LDAP schema modified a bit. Please upgrade.
2109       
2110        - LDAP backend works !
2111       
2112        - repykota and warnpykota allow the root user to pass
2113          users or groups names on the command line. Users
2114          and groups names may contain wildcards.
2115         
2116        - repykota and warnpykota only reports or warns the
2117          current user when launched by non-root users.
2118         
2119        - Minor bug fixes. 
2120   
2121    - 1.09alpha1 :
2122   
2123        - More work on LDAP storage backend. Many options
2124          were added to /etc/pykota.conf to give some
2125          hints to the LDAP storage backend.
2126         
2127        - Severe database access optimizations were done by
2128          rewriting most of the Quota Storage backends drivers.
2129     
2130    - 1.08 :
2131   
2132        - Major bug fix wrt LPRng support for remote jobs.
2133       
2134        - Major bug fix wrt increase/decrease account balances.
2135       
2136    - 1.08alpha8 :
2137   
2138        - Code refactoring.
2139       
2140        - A single user/password pair is used to connect
2141          to the database backend. The storageuser configuration
2142          field, and its associated passwords storageuserpw, are
2143          not used anymore.
2144         
2145        - You can now set PyKota in debug mode, see sample configuration 
2146          file for details.
2147          WARNING : only Quota Storage backend queries are logged in
2148          debug mode, for now.
2149       
2150    - 1.08alpha7 :
2151   
2152        - Very latest LDAP schema.
2153       
2154        - Code enhancement wrt easy pluggability of PyKota attributes
2155          and object classes into an existing LDAP directory.
2156       
2157    - 1.08alpha6 :
2158   
2159        - Minor bug corrections
2160       
2161        - More work on LDAP : new schema
2162       
2163    - 1.08alpha5 :
2164   
2165        - More good work on LDAP storage.
2166          repykota now works reasonably well with the sample LDAP directory.
2167       
2168    - 1.08alpha4 :
2169   
2170        - LDAP schema included.
2171          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2172          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2173          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2174          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2175          MAILING LIST.
2176         
2177    - 1.08alpha3 :
2178   
2179        - External accounting methods were partly rewritten :
2180         
2181          - No more "broken pipe" should happen.
2182         
2183          - They now take care of the number of copies
2184            This may be unneeded though, if the postscript
2185            file already does this, because this would
2186            overcharge users (number of copies counted
2187            two times). NEEDS MORE TESTING.
2188           
2189          - The sample configuration file now contains 
2190            an external accounting method example which should
2191            work with all DSC compliant Postscript files.
2192           
2193        - Some small bugs were fixed.   
2194       
2195    - 1.08alpha2 :
2196   
2197        - Now works with net-snmp v5.0 and above.
2198          It already worked, but the sample configuration
2199          file didn't contain appropriate values...
2200       
2201    - 1.07 : Release of the Shame !
2202   
2203        - The external accounting methods driver was left out of
2204          the CVS tree. Nobody could use it since it wasn't included !
2205         
2206    - 1.06 :
2207   
2208        - Severe bug fixed : if you had a printer in
2209          power saving state which couldn't answer immediately,
2210          a bug was triggered.
2211          It was caused by a bad copy/paste which
2212          forgot to import a Python module at run time.
2213         
2214    - 1.05 :
2215   
2216        - External accounters are finally available !
2217          This means that you can plug any page accounting
2218          method you like by setting the appropriate
2219          'accounter' field in /etc/pykota.conf
2220          See the sample conf/pykota.conf.sample to
2221          learn how to do.
2222         
2223          NB : Both 'external' and 'stupid' accounting methods
2224               account a job size just before *this* job is
2225               sent to the printer.
2226               The original 'querying' method accounts a job
2227               size just before *the next* job is sent to
2228               the printer.
2229       
2230    - 1.05alpha3 :
2231   
2232        - A 'stupid' and unreliable accounting method was
2233          implemented to serve as an example on how to
2234          do this sort of things. This method only counts
2235          the 'showpage' statements in the input data.
2236          See sample configuration file for details.
2237          Pluggable accounting methods work, but I advise
2238          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2239          It is not reliable enough to be used.
2240          Use the 'querying' accounting method instead.
2241         
2242    - 1.05alpha2 :
2243   
2244        - Pluggable accounting methods.
2245       
2246        - Better error handling.
2247       
2248    - 1.05alpha1 :
2249   
2250        - SECURITY file added to help improve PyKota's security.
2251       
2252        - Extracting the printer's internal page counter is now
2253          tried several times, waiting several seconds between
2254          two tries. This lets the time to warm up for some printers
2255          which don't answer when they are sleeping (my Apple
2256          LaserWriter 16/600 PS is in this case, maybe others too)
2257         
2258        - Small display bug fixed in repykota
2259         
2260    - 1.04 :
2261   
2262        - Default print policy for users/groups unknown from
2263          the print quota system is now DENY instead of ALLOW,
2264          since ALLOW can generate inaccurate results
2265          (incorrect job sizes charged to the wrong persons)
2266         
2267        - LPRng support works !
2268       
2269        - A bug was introduced some time ago wrt printers' default
2270          policy for unknown users. It is now corrected.
2271       
2272        - repykota now displays prices per job and per page for each
2273          printer, if they are defined.
2274         
2275        - Minor display bug fixed in repykota.
2276       
2277        - Problem when running repykota with an empty database was fixed.
2278       
2279    - 1.03 :
2280   
2281        - Upgrade script included for earlier versions.
2282          Please look inside the initscripts subdirectory.
2283          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2284         
2285        - repykota now reports account balances too.
2286       
2287        - PyKota now has a nice logo, see the logos
2288          subdirectory.
2289       
2290        - Manual pages were finally updated.
2291       
2292        - Group quotas seem to work now !
2293       
2294        - The new database schema allows to keep an history of all
2295          jobs as well as charge users per page and/or per job,
2296          and track users' account balance.
2297         
2298        - edpykota now accepts much more command line options to 
2299          use the new functionnalities. See edpykota --help for
2300          details.
2301         
2302        - The installation script now allows to install the sample
2303          configuration file during first installation.
2304         
2305        - More group quota code works, but still not finished. 
2306       
2307        - The CGI script displays a link to PyKota's website.
2308       
2309        - The job history is now kept, this will allow per-period
2310          reports in the future.
2311         
2312        - After having modified the quota for an user with edpykota,
2313          a quota check is done to eventually warn the user/admin about
2314          a quota which is too low to print.
2315         
2316        - A workaround is provided for HP Printers : their internal
2317          page counter is only saved to NVRAM in a 10 increment, so
2318          if you switch them off and then on, the reported page counter
2319          may be lower than the real number of pages printed.
2320          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2321          We unconditionnally set the last job's page count to
2322          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2323          in this case.
2324          For a more accurate accounting, never switch your HP printers
2325          off.
2326         
2327        - A fix is provided for printers which only have a volatile 
2328          page counter (reset to 0 every time you switch the printer on)
2329          This should allow PyKota to work reasonably fine with HP Laserjet
2330          4L/5L/6L, not perfect, but better than nothing.
2331          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2332          For a more accurate accounting, never switch your HP printers
2333          off. This is untested, please report any problem.
2334         
2335        - A bug was fixed when edpykota --add was used with users who already
2336          had a quota on the specified printer.
2337         
2338        - A small display bug in repykota was introduced in preliminary
2339          1.03 versions, and fixed later on.
2340         
2341        - Some minor bugs which happened in rare situations were fixed.
2342       
2343        - Support for AppleTalk printers was added, see sample configuration
2344          file for details.
2345         
2346        - Users and group printing can now be controlled (limited) either by 
2347          print quota or by account balance.
2348       
2349    - 1.02 :
2350   
2351        - The installation script now checks for software availability
2352          and in case a software is missing asks the user if he
2353          wants to continue with the installation or abort it.
2354         
2355        - The configuration file pykota.conf is now expected to be
2356          found in /etc instead of in /etc/cups
2357          The installation script prompts the user to see if he
2358          wants to move an old configuration file to the new location
2359          if needed.
2360         
2361        - Improved documentation.
2362       
2363        - You can now set the tcp/ip port on which the Quota Storage
2364          Server is listening, see sample configuration file for details.
2365       
2366        - Better general error handling.
2367       
2368        - Upgrade script for pre 1.01 PostgreSQL database schema is now
2369          included as well.
2370       
2371    - 1.01 :
2372   
2373        - The configuration file now accepts an option   
2374          to choose the recipient(s) of the email messages :
2375         
2376            - DevNull means no one will receive them.
2377            - User means only the user will receive them.
2378            - Admin means only the admin will receive them.
2379            - Both means the User and the Admin will receive them.
2380           
2381        - The configuration file now uses hard-coded default values
2382          when an option is not set. See sample configuration file
2383          for details.
2384         
2385        - Manual pages are included since 1.00, but I forgot to   
2386          add this information to this file.
2387         
2388        - Redistribution terms for the official package have 
2389          softened and are now fully GPL compatible :
2390          unrestricted modification is now allowed even for
2391          the version number.
2392
