Revision 2074, 59.4 kB (checked in by jalet, 19 years ago)

Optimize print job parsing by avoiding to pass the job's datas through
PyKota's internal parser if the special construct "software()" is used
with no argument in the 'accounter' directive.

22PyKota NEWS :
23       
24    - 1.21alpha27 :
25   
26        - Allows software() (no arguments) to the software accounting
27          directive. This saves a lot of CPU since the job is not
28          parsed again : the precomputed size is used directly in this
29          case.
30         
31        - epykota's --prototype option now works fine with accounts
32          limited by balance.
33         
34    - 1.21alpha26 :
35   
36        - Fixed the handling of the 'maxdenybanners' directive.
37       
38        - Introduced the 'denyduplicates' directive.
39       
40        - Fixed some database related glitches.
41       
42    - 1.21alpha25 :
43   
44        - The job's size is now always precomputed, even when
45          'enforcement' is not set to 'strict'.
46         
47        - Introduction of the new 'trustjobsize' configuration directive
48          to workaround some problematic printers. See the sample
49          configuration file for details.
50         
51    - 1.21alpha24 :
52   
53        - Big database structure changes. An upgrade script
54          is now included for PostgreSQL. LDAP users may just
55          want to copy the new schema in place.
56         
57        - edpykota now recognizes the -o | --overcharge command line
58          option to set an overcharging or undercharging factor
59          on each print job's cost for a particular user.
60         
61        - repykota's output format has changed an is not limited to 
62          80 characters wide anymore. People who used to parse
63          repykota's output in their own tools are strongly advised
64          to parse dumpykota's output instead.
65         
66        - Introduction of the new 'maxdenybanners' configuration directive
67          to allow up to N (the directive's value) deny banners to be
68          printed even if the print account is forbidden to print.
69         
70        - Better detection of the number of copies in the PostScript parser.
71       
72    - 1.21alpha23 :
73   
74        - Traditional Chinese translation added.
75   
76        - Several fixes and performance improvements with the LDAP backend.
77       
78    - 1.21alpha22 :
79   
80        - edpykota's --delete command line option doesn't consider
81          '*' to be the default argument anymore :-)
82         
83    - 1.21alpha21 :
84   
85        - dumpykota.cgi can now be run as a normal user as opposed to
86          a PyKota administrator. No read access to pykotadmin.conf is
87          necessary anymore. This CGI scripts now honors the REMOTE_USER
88          environment variable just like printquota.cgi does, see
89          the file cgi-bin/README for details.
90          The command line tool dumpykota must still be run by a PyKota
91          administrator.
92         
93        - Fix exception's name error due to a change in recent versions
94          of PygreSQL.   
95         
96    - 1.21alpha20 :
97         
98        - Big bug fix wrt the datelimit field which was never reset.
99         
100    - 1.21alpha19 :
101   
102        - Introduction of the new dumpykota.cgi CGI script, which
103          allows third party tools like phpPrintAnalyzer to be
104          interfaced in real time with PyKota. To use it you
105          may have to change your web server's configuration,
106          please see pykota/cgi-bin/README
107         
108    - 1.21alpha18 :
109   
110        - Now dumpykota can dump the job history into CUPS' page_log
111          format (even when the printing system is LPRng). This allows
112          people to use tools like PrintAnalyzer or phpPrintAnalyzer
113          (two completely different beasts) with PyKota.
114         
115    - 1.21alpha17 :
116     
117        - Fixed field type's name in XML dumps.
118       
119        - Now drops priviledges to user 'pykota' when launched as root
120          (directly or as a CUPS backend), if such an user exists.
121         
122        - Fixed PCL3/4/5 parser for some drivers' output.
123       
124    - 1.21alpha16 :
125   
126        - fixed several recently introduced bugs in LDAP backend code,
127          thanks to Matt Hyclak.
128         
129    - 1.21alpha15 :
130     
131        - Normalized field names between LDAP and PostgreSQL backends
132          in dumpykota's output.
133         
134        - dumpykota filtering capabilities are now supported within
135          the LDAP backend too.
136         
137    - 1.21alpha14 :
138   
139        - dumpykota now supports extended filtering possibilities
140          with the PostgreSQL backend (LDAP support will come soon).
141         
142    - 1.21alpha13 :
143   
144        - Added a --debug command line option to pkpgcounter, so
145          that people may see what really happens, and what will
146          be available in the future :-)
147         
148    - 1.21alpha12 :
149   
150        - Fixed a bug with non standard pkbanner command lines.
151       
152        - Now logs as errors the differences between precomputed and
153          computed job sizes. **CUPS only for now**
154         
155    - 1.21alpha11 :
156   
157        - Now user and group print quota entries can be stored directly
158          below the user or group with the LDAP backend, using them
159          as branches. Thanks to Stefan Wold for the patch.
160          See the sample configuration file for details.
161         
162        - TLS is now supported with the LDAP backend. Thanks to Stefan
163          Wold for the patch.
164          See the sample configuration file for details.
165         
166        - edpkota now accepts the -U | --used value command line argument
167          to preset the page counters to an initial value. Thanks to
168          Wilson Roberto Afonso and Matt Hyclak for the patch.
169         
170    - 1.21alpha10 :
171   
172        - Now automatically reconnects up to three times if the LDAP server
173          returned an error, possibly due to a timeout.
174         
175    - 1.21alpha9 :
176   
177        - Now searches the configuration files in 'pykota' system user's
178          home directory. The 'pykota' system user and group have
179          to be created by the system administrator, and given
180          sufficient permissions to PyKota's configuration files.
181         
182    - 1.21alpha8 :
183   
184        - Added the new reject_unknown directive to reject the
185          creation of user or groups which are unknown to the system.

198   
199        - Improved ESC/P2 miniparser for Stylus Photo printers.
200       
201        - Implemented the --savetoner command line option to pkbanner.
202       
203        - Improved pkbanner's help and messages.
204

210          thanks to Wilson Roberto Afonso.
211       
212    - 1.21alpha3 :
213   
214        - PyKota can now generate its own banners, and either account
215          for them or not, depending on newly introduced directives
216          in pykota.conf
217          Thanks to Matt Hyclak for the patch.
218         
219    - 1.21alpha2 :
220   
221        - Installation script is now non interactive again, as it should
222          have stayed from the beginning. Dependencies checking can
223          be done by launching the checkdeps.py command.
224         
225    - 1.21alpha1 :
226   
227        - added an IPP messages miniparser. Extraction of the client
228          hostname is now considered to be fiable, at least until
229          the CUPS developpers change something...
230       
231    - 1.20 :
232   
233        - Version number changed.
234       
235    - 1.20beta :
236   
237        - Norwegian (Bokm� preliminary translation added.
238       
239        - German translation was finalized.
240       
241        - Greek translation was finalized.
242       
243        - For urgent legal reasons, a "privacy" directive has been added
244          to pykota.conf, to hide jobs' title, filename and options
245          in the history.
246         
247        - Minor changes in the debian directory.
248       
249    - 1.20alpha27 :
250   
251        - Fixed many problems with translation files. In particular
252          the brasilian portuguese translation file was incorrectly
253          installed into the french "breton" locale directory.
254         
255        - Finished French translation. 
256         
257    - 1.20alpha26 :
258   
259        - LPRng support code should now better detect network
260          printers' hostnames or IP addresses.
261         
262        - Fix for recently introduced bug in LPRng support.
263       
264        - Fix for incorrect locale setting when starting.
265       
266    - 1.20alpha25 :
267   
268        - pkprinters allows --list to normal users, but require user
269          to be a PyKota administrator when another command line
270          option is used.
271         
272        - pkhint doesn't use absolute path to search for helper commands
273          anymore.
274         
275        - Spanish translation ready for 1.20.   
276       
277    - 1.20alpha24 :
278   
279        - Now warnpykota only warns users limited by balance once.
280       
281        - Now warnpykota only warns users who have ever printed,
282          to not cause confusion to users who have just opened
283          their account.
284       
285        - Prepared help messages for translations.
286       
287    - 1.20alpha23 :
288   
289        - Add workaround for locale problem.
290       
291    - 1.20alpha22 :
292   
293        - Hopefully final fix for data encoding charset.
294       
295        - edpykota now refuse to work if the user is not a PyKota admin.
296       
297        - Fixes a recently introduced bug with users groups and PostgreSQL.
298       
299    - 1.20alpha21 :
300   
301        - Now dumpykota refuses to launch if the current user is not
302          a PyKota administrator (a PyKota administrator is an user
303          allowed to read the pykotadmin.conf file).
304         
305        - Now any PyKota administrator can use repykota and warnpykota
306          with additionnal arguments, not only the root user.
307         
308        - Improved documentation a bit.
309       
310    - 1.20alpha20 :
311   
312        - Reduced delay in internal SNMP and PJL_over_TCP handlers
313          from 2 to 1 second.
314       
315        - dumpykota can now output XML.
316       
317    - 1.20alpha19 :
318

320       
321        - Finished implementation of LDAP support in dumpykota.
322       
323        - The md5 sum of the job's datas is now available as an
324          hexadecimal digest in the PYKOTAMD5SUM environment variable.
325         
326        - The description, filename, title, and options fields
327          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
328          Proper charset is used during extraction from the database.
329         
330    - 1.20alpha18 :
331   
332        - Experimental autopykota command to initialize user
333          account and quota entries on first print while not
334          resetting the balance value if not needed.
335         
336        - Added the new "winbind_separator" directive to strip
337          out the Samba/Winbind domain name while printing if
338          needed (Off by default).
339         
340    - 1.20alpha17 :
341   
342        - Added --hardreset command line option to edpykota.
343       
344        - Fixed problem with accented chars in title, filename
345          or options and LDAP backend.
346         
347    - 1.20alpha16 :
348   
349        - Internal handling of socket based PJL queries over
350          port tcp/9100 is now available with the magic
351          'pjl' value in the hardware accounter.
352         
353    - 1.20alpha15 :
354   
355        - LDAP pykotaAccountBalance objects were always created
356          attached to the pykotaUser objects. This is now
357          fixed and the value of balancebase in pykota.conf
358          is now correctly used.
359         
360    - 1.20alpha14 :
361   
362        - Belgian translations added (copy of the french ones).
363       
364        - External hardware accounter now loops until
365          a result can be read correctly.
366         
367        - pkhint now suggest the internal snmp handling instead
368          of the external one.
369         
370    - 1.20alpha13 :
371     
372        - Hardware accounter now accepts the special
373          'snmp' value, meaning ALL is done from main code
374          without launching any subprocess.
375          You need the http://pysnmp.sf.net Python module
376          for this to work (tested with v3.4.2)
377         
378        - Increased delay between two loops iterations 
379          to 2 seconds in waitprinter.sh to diminish
380          CPU load.
381         
382    - 1.20alpha12 :
383   
384        - waitprinter.sh rewritten from scratch to wait
385          for printer status stabilization.
386       
387    - 1.20alpha11 :
388   
389        - Generic data dumper 'dumpykota' introduced.
390          Works only with PostgreSQL backend for now.
391         
392    - 1.20alpha10 :
393   
394        - Added fix for incorrect job's size computation when
395          hardware accounting fails.
396         
397    - 1.20alpha9 :
398   
399        - Small fixes wrt subprocesses.
400       
401    - 1.20alpha8 :
402   
403        - Added full support of PCL3 : HP Deskjet printers are now
404          supported.
405       
406    - 1.20alpha7 :
407   
408        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
409          Needs more work, but no documentation is available.
410       
411    - 1.20alpha6 :
412     
413        - Improved mailandpopup.sh script.
414       
415        - Small fixes for LPRng.
416       
417        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
418          hostname or IP address. Set to 'localhost' when not
419          meaningful.
420         
421        - Fixed issue with how mod_auth_ldap Apache modules
422          fills the REMOTE_USER environment variable.
423         
424        - Fixed a bug in LDAP user deletion code.
425       
426    - 1.20alpha5 :
427     
428        - Introduces the new configuration directive 'onaccountererror'
429          to specify what must be done whenever the software or
430          hardware accounter fails. Allowed values are 'continue' and
431          'stop' (default).
432         
433        - Minor fix in software accounter for a recently introduced
434          problem.
435         
436    - 1.20alpha4 :
437   
438        - Added support for more ghostscript devices in ESC/P2
439          analyzer : stcolor, st800, escp, escpc are now supported.
440         
441    - 1.20alpha3 :
442       
443        - Small improvement in PostScript parser to avoid being
444          fooled by a change in number of copies :
445          The user can't ask for 200 copies of page 1 and 1 copy
446          of page 2 to fool PyKota anymore :
447          this would have been accounted for as 1 copy only, but
448          now the maximum value seen is used.
449         
450        - Relax checks for PCL5 header to accomodate some strange
451          printer drivers.
452         
453        - Now hardware accounting method works like software
454          accounting method wrt the subprocess' output.
455         
456        - Hardware and Software accounting stop the print queue 
457          when the accounting subprocess didn't work. This will
458          be configurable in the near future.
459         
460    - 1.20alpha2 :
461   
462        - Now software accounting method reads accounter's
463          answer until a line with a single integer is
464          obtained or until all of its output has been read.
465          This should fix the problem some people have
466          when strange locale related messages are sent
467          when running subprocesses (Solaris only ?).
468         
469        - First version of ESC/P2 analyzer. Seems to work
470          ok at least with 'epson', 'epsonc', 'eps9mid'
471          and 'esp9high' ghostscript devices. Needs more
472          work to correctly analyze other devices.
473       
474    - 1.20alpha1 :
475   
476        - Fixed problem with number of copies in PCLXL parser.
477       
478        - Fixed problem with number of copies in PCL5 parser,
479          when number of copies was set outside of and before first
480          page.
481       
482        - Added workaround for number of copies directly set in
483          PostScript code.
484         
485        - Added german translation.
486       
487        - Fixed problem on first print for user group quota when
488          "enforcement: strict" is used.
489       
490        - Fixed interpolation problem in french translation.
491       
492    - 1.19 :
493   
494        - Updated existing translations.   
495       
496        - Added final Thai and Greek translations.
497       
498        - Minor last minute bug fixes.
499       
500    - 1.19beta :
501   
502        - LPRng support for both software and hardware accounting seems
503          to be OK.
504         
505        - Translation files fixed because of fuzzy matching problem. 
506       
507        - Fixed path to Swedish translation: 'sv' instead of 'se'.
508       
509        - Added first draft of Thai translation.
510       
511        - Fixed some minor bugs with Pychecker.
512       
513    - 1.19alpha35 :
514   
515        - Generic PDL analyzer now supports Binary PostScript documents
516          in addition to DSC compliant ones.
517       
518    - 1.19alpha34 :
519   
520        - LPRng support : software accounting seems to work fine,
521          but hardware accounting doesn't work yet.
522   
523    - 1.19alpha33 :
524   
525        - pykosd now accepts command line arguments. Enjoy !
526          NB : due to a bug in xosd, you need xosd version 2.2.8
527          or higher if you don't use the default C locale.
528         
529    - 1.19alpha32 :
530   
531        - Early (not working) version of the LPRng support rewrite.
532       
533        - Saner default configuration file.
534       
535    - 1.19alpha31 :
536   
537        - Fixed a double Python2.1 incompatibility with newer versions,
538          which prevented the PCL5 and the PCLXL parsers to work with
539          this older version of Python.
540         
541    - 1.19alpha30 :
542   
543        - Introduction of preliminary version of the pykosd command
544       
545        - Usernames, Groupnames and Printernames can now contain
546          ANY character, expected '/' and '@'.
547       
548        - Integrated most of the Debian work from Sergio
549          Gonz�z Gonz�z
550         
551    - 1.19alpha29 :
552   
553        - PCLXL parser should now correctly handle number of
554          copies set for each page.
555         
556        - Added testsuite for generic PDL analyzer.
557       
558        - Typo fixed in PCLXL parser.
559       
560        - Correctly dispatches error messages depending on the
561          situation : tools which can be run interactively will
562          ALWAYS output their logs to stderr, excepted for
563          their DEBUG messages, for which the "logger:"
564          directive as set in pykota.conf will be honored.
565          Tools which can't be run interactively will ALWAYS
566          honor the "logger:" directive as set in pykota.conf
567         
568    - 1.19alpha28 :
569   
570        - The description field for printers can now be set,
571          and is displayed in reports.
572         
573        - Fixed a small problem in SQL backend code.
574         
575        - Improved pkhint
576       
577        - First working PCL6 (aka PCLXL) parser !
578          Doesn't handle copies yet.
579       
580    - 1.19alpha27 :
581   
582        - Additionnal 10% speed increase in PCL5 parser for GhostScript
583          generated files (untested yet with other PCL files).
584         
585        - Reintroduced the use of mmap in PCL5 parser : this speedups
586          PCL5 parsing by almost 4 times.
587          This 4x with the 3x below give us in fact a twelvefold increase
588          in performance for PCL5 parsing !
589         
590        - The Python accelerator Psyco is now used if available
591          in the generic PDL parser : it speedups PCL5 parsing by
592          almost three times automagically.
593         
594    - 1.19alpha26 :
595   
596        - Fixed PCL5 parser according to the sources of rastertohp.
597       
598        - Fixed number of copies handling in PCL5 parser : the number
599          of copies could vary from page to page.
600         
601        - Added more debug information to PCLXL parser. 
602       
603    - 1.19alpha25 :
604   
605        - Added new "description" field to printers in both
606          PostgreSQL and LDAP. No code to handle this yet.
607         
608        - Reversed the fix for power save mode in printers : 
609          no paper or tray open would have caused people to
610          be undercharged.
611         
612        - Preliminary version of MySQL initialization script.
613         
614    - 1.19alpha24 :
615   
616        - Native PDF parsing code now works perfectly with
617          Python 2.1 and above, and is way faster than before.
618          GhostScript is not used anymore to convert PDF to PS,
619          because PDF is parsed directly.
620         
621    - 1.19alpha23 :
622   
623        - Fixed waitprinter.sh wrt PowerSave mode and some
624          printers. Thanks to Ryan Suarez.
625       
626        - Smart PDL analyzer now recognizes PDF too : two
627          PDF parsing methods are used : a native one which
628          is very fast but requires Python 2.3 or above, and
629          a slower one which uses Ghostscript. PyKota detects
630          automatically which method to use depending on your
631          version of Python.
632       
633        - All tracebacks now include PyKota's version number.
634         
635    - 1.19alpha22 :
636   
637        - Ensures that the file pointer for job's data is
638          reset to the start of the job's datas after the
639          job's size pre-computation phase.
640         
641        - Improved PostScript detection code for bad drivers
642          which don't correctly switch languages between PJL
643          and PS.
644       
645        - Even better debugging code.
646       
647    - 1.19alpha21 :
648   
649        - Additionnal check.
650       
651    - 1.19alpha20 :
652   
653        - More complete logging messages wrt accounters.
654       
655        - Now catches early failures occuring when the configuration
656          files are parsed.
657       
658    - 1.19alpha19 :
659   
660        - Fixed over-verbose exits when displaying help
661          or version.
662         
663        - Extended some PATH in the shell scripts 
664       
665        - Deleting an user now also deletes his payments history.
666       
667        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
668          cause problems.
669
670    - 1.19alpha18 :
671   
672        - History of payments is now stored in the database, and
673          updated each time an user's balance is modified with
674          edpykota --balance. This history represents each time
675          the user was given some positive or negative credit,
676          but doesn't reflect price paid for jobs, which appear
677          in the jobs history instead.
678         
679        - Jobs history web reports now include the job's size in
680          bytes. Also columns were reordered to render the report
681          more easily readable.
682         
683    - 1.19alpha17 :
684   
685        - Mysterious bug (program exited unexpectedly without leaving
686          any log message) which occured once in a while when
687          cancelling jobs should be fixed now.
688         
689        - New 'crashrecipient' directive. Disabled by 
690          default. See sample configuration file to see how
691          to activate it. It is suggested that you activate it.
692         
693        - New PYKOTAJOBSIZEBYTES environment variable exported, 
694          which contains the job's size in bytes. Empty jobs
695          are now denied. This value is now stored in the job
696          history (but not yet displayed from the web interface)
697         
698        - Preliminary work on payments storage : the PostgreSQL 
699          and LDAP schemas should be OK now, but no code is written
700          yet to support this functionnality.
701         
702    - 1.19alpha16 :
703   
704        - the newuser and newgroup LDAP specific directives now accept
705          a second parameter to attach(), "fail" or "warn". If no entry
706          is found to attach PyKota attributes to, and "fail" was used,
707          then action is aborted and program exits in error. If "warn"
708          is used, a new entry is created but a warning message is logged.
709         
710        - The job's originating hostname is now stored in the database,
711          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
712       
713    - 1.19alpha15 :
714   
715        - The old pykota filter is now removed. This means that
716          currently PyKota doesn't support LPRng anymore, but
717          LPRng support will be re-added, improved, in the near future.
718         
719    - 1.19alpha14 :
720   
721        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
722          are now exported as environment variables.
723         
724        - Heavy CPU usage is now completely fixed it seems, by
725          introducing some 0.01 second sleeping when nothing to do.
726         
727        - Pre-computation of the job's size is now only
728          done when enforcement is "STRICT", this saves
729          CPU for people who don't want to use this new
730          feature.
731         
732        - New 'enforcement' directive which accepts either
733          STRICT or LAXIST. See sample configuration file
734          for details.
735         
736    - 1.19alpha13 :
737   
738        - Get back to an old version of the polling loop which
739          worked fine, but non-optimally. Will be optimized
740          as time permits.
741         
742    - 1.19alpha12 :
743   
744        - Job's size is now precomputed unconditionnally using
745          the generic PDL analyzer.
746          NB : This value is not yet used to pre-allow/deny the
747          job.
748       
749    - 1.19alpha11 :
750   
751        - The pykota filter is now completely deprecated and
752          can't be used anymore. LPRng users MUST download
753          an older version of PyKota. CUPS users MUST use
754          cupspykota. Better support for LPRng will come
755          in the near future.
756         
757    - 1.19alpha10 :
758   
759        - pykotme now uses generic PDL Analyzer directly instead
760          of spawning a new process.
761         
762        - Improvements to generic PDL Analyzer.
763       
764        - 25% Speedup in PCL parser. Getting more of the Python version
765          will probably be difficult, since the completely table driven
766          parser I wrote is slower than the original algorithm. Then,
767          the original algorithm is still used for now.
768          Probable that more speed could be achieved using mmap, at the
769          expense of severe memory consumption.
770       
771        - configuration simplifications : the "accounter" directive's
772          'hardware' arguments now accepts what was in the "requester"
773          directive as it's content. The "requester" directive is not
774          supported anymore. See sample configuration file for details.
775       
776    - 1.19alpha9 :
777       
778        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
779       
780        - pykotaOptions LDAP attribute now accepts non-ascii characters
781          too.
782         
783        - First try at cupspykota main loop rewrite
784       
785    - 1.19alpha8 :
786   
787        - 'querying' accounting method is now called 'hardware'
788       
789        - 'external' accounting method is now called 'software'
790       
791        - 'stupid' accounting method doesn't exist anymore
792       
793        - 'snmp' requester doesn't exist anymore
794       
795        - code simplifications in external requester
796       
797    - 1.19alpha7 :
798     
799        - Database schema change (both LDAP and PostgreSQL) to
800          allow storage of the job-originating-hostname attribute.
801          An SQL upgrade script is present. The code is not yet
802          capable of setting/retrieving this attribute. Support
803          for this functionnality will be added in the future.
804         
805    - 1.19alpha6 :
806   
807        - problems connecting to SMTP servers are now catched.
808       
809        - pykotme now uses pkpgcounter to compute the size of the
810          job. This modification adds PCL5 and soon PCLXL (PCL6)
811          support. You can now get quotes for PCL in addition to
812          PostScript.
813         
814        - pkpgcounter now includes first try at PCLXL parser. 
815          It is currently disabled until it's finished.
816         
817    - 1.19alpha5 :
818   
819        - cupspykota polling loop fix for MacOSX (at least)
820       
821        - logging subsystem now logs PID too, to ease diagnosing
822          problems under heavy load.
823         
824        - pkpgcounter enhancements.
825       
826        - pkprinters --skipexisting now tells pkprinters to not
827          modify existing printers when --add is used.
828          pkprinters logs a warning message whenever --add is
829          used and a printer already exists.
830         
831        - LDAP schema now allows accented chars in pykotaFileName
832          and pykotaTitle attributes.
833       
834    - 1.19alpha4 :
835   
836        - a bad copy&paste prevented pkpgcounter to work at all, this
837          is now fixed.
838         
839        - improved PCL support in pkpgcounter, with the use of
840          HP PCL/PJL Reference Set
841          PCL5 Printer Language Technical Quick Reference Guide
842       
843        - pkpgcounter now uses mmap to speed things up : duration
844          is halved with the sample 87 pages PCL document I use for
845          testing.
846         
847    - 1.19alpha3 :
848   
849        - pkprinters now accepts the --list command line argument
850          to list informations about printers.
851         
852    - 1.19alpha2 :
853   
854        - pkpgcounter is now included as a smart external
855          accounter which can handle both PostScript and PCL.
856         
857    - 1.19alpha1 :
858   
859        - PYKOTALIMITBY environment variable is now exported too.
860       
861        - Inclusion of Michele Baldessari's work on autotools.
862       
863    - 1.18 :
864   
865        - Improved documentation
866       
867    - 1.18beta2 :
868     
869        - Fix for raw jobs with cupspykota
870       
871    - 1.18beta :
872   
873        - Small fix for new waitprinter.sh script
874       
875        - Better tracebacks on error conditions
876       
877        - Improved translations
878       
879        - Improved documentation
880       
881    - 1.18alpha15 :
882
883        - waitprinter.sh replaced by a new and possibly faster
884          and more powerful one.
885   
886        - Names can now begin with a digit.
887       
888        - Stability improvement for quotas set on printers groups.
889       
890    - 1.18alpha14 :
891   
892        - Catches more (all ?) problems with SMTP servers instead
893          of breaking.
894         
895        - Italian translation added.
896       
897    - 1.18alpha13 :
898   
899        - Pre and Post hooks are now available in the pykota
900          filter as well.
901         
902        - The pykota filter doesn't check last user's quota
903          anymore when delayed hardware accounting is used :
904          this will be done anyway the next time the last
905          user will print again. This saves some database
906          queries which are unneeded.
907       
908    - 1.18alpha12 :
909   
910        - Pre and Post hooks to external commands with many
911          many environment variables available are useable
912          from the cupspykota backend.
913          See sample configuration file for details and help.
914         
915    - 1.18alpha11 :
916   
917        - Hopefully final fix wrt groups (users and printers)
918       
919    - 1.18alpha10 :
920   
921        - Fixed nested printer groups accounting.
922       
923        - Fixed user groups + printer groups problem.
924       
925    - 1.18alpha9 :
926   
927        - Fix for LDAP problem when job price was 0.
928       
929        - Fix for empty user groups with LDAP.
930       
931        - Preliminary version of the snmpprinterstatus command added.
932       
933    - 1.18alpha8 :
934   
935        - Don't retrieve data when not needed.
936          This avoids many database queries.
937       
938    - 1.18alpha7 :
939   
940        - New experimental ldapcache directive to improve
941          LDAP caching.
942         
943    - 1.18alpha6 :
944       
945        - New configuration directive added : maildomain
946          to specify the domain to send mail to when user
947          email address is not set in PyKota database.
948         
949        - More complete email message headers. 
950         
951    - 1.18alpha5 :
952   
953        - Debian packaging specific files, contributed by
954          Peter Hawkins are now included in the project's tree.
955         
956        - Preliminary work on future low-level LDAP caching to speed
957          up modifications (at least).
958         
959    - 1.18alpha4 :
960   
961        - Applied some of the modifications suggested by
962          Peter Hawkins, for better Debian integration.
963          Most notably cupspykota, pykota, and the shell
964          scripts are now installed into /usr/share/pykota
965          instead of into /usr/bin
966          BEWARE : double check that your symbolic link
967          to cupspykota is correct, and that your pykota.conf
968          file use correct path for the shell scripts like
969          waitprinter.sh and al.
970         
971        - pkhint command added, to help in configuring correct
972          accounting method for PyKota.
973         
974    - 1.18alpha3 :
975   
976        - Fixed a rare bug in cupspykota backend which gave
977          incorrect "CUPS backend died abnormally" messages.
978       
979    - 1.18alpha2 :
980   
981        - Added the pkprinters command line tool to manage printers
982          exclusively.
983       
984    - 1.18alpha1 :
985   
986        - Preliminary work on Relationnal Database Independance.
987       
988        - Sample report made from OpenOffice.org added as PDF and SXC.
989       
990    - 1.17 :
991   
992        - Finalized release.
993       
994    - 1.17alpha2 :
995   
996        - Fix stupid software accounting bug in the CUPS backend.
997

1035       
1036          SUM((NbPages * PricePerPage) + PricePerJob)
1037         
1038          For current printer and all the printers groups it is
1039          a member of, if any.
1040         
1041          This may be difficult to grasp, but offers unprecedented
1042          flexibility.

1082       
1083    - 1.16alpha18 :
1084   
1085        - Initial code for printer groups support. Printer groups have
1086          to be added with external tools like psql or gq for example.
1087          Printer groups seems to work fine with users. Untested with user
1088          groups for now.
1089
1090        - Several minor visual problems fixed in reports.
1091       
1092        - Fixed a bug in LDAP date handling.

1098          for details.
1099       
1100        - Several environment variables are now exported when executing
1101          external commands (accounters, requesters, mailers) :
1102           
1103            PYKOTAUSERNAME => user who is printing
1104            PYKOTAPRINTERNAME => printer on which the job is being sent
1105            PYKOTATITLE => Job's title
1106            PYKOTAFILENAME => Job's filename
1107            PYKOTACOPIES => number of copies asked
1108            PYKOTAOPTIONS => print command options (-o with CUPS)
1109         
1110    - 1.16alpha17 :
1111   
1112        - Added portugues translation.
1113       
1114        - Major code refactoring in accounters.

1119          have nice looking and useful web based reports (in the future).
1120       
1121        - Added utolower configuration option to convert all usernames
1122          to lowercase during printing.

1132          results in the job being cancelled or stopped, depending
1133          on the printing system.
1134         
1135    - 1.16alpha13 :
1136   
1137        - Small bugfix wrt Python v2.1
1138       
1139        - If username is an empty string, user root is assumed.
1140       
1141        - 'postgresql' is not recognized anymore as a storage backend,
1142          you have to use 'pgstorage' instead. 'postgresql' used to
1143          be supported for compatibility with very old PyKota versions,
1144          this is not the case anymore.
1145         
1146    - 1.16alpha12 :
1147   
1148        - Job price added to job history, to keep accounting correct
1149          if a printer price per page or per job is modified and the
1150          history is not reset : the history would have given a false
1151          amount of money charged before the printer's prices were
1152          modified, this addition solves the problem.
1153         
1154    - 1.16alpha11 :
1155   
1156        - Some preliminary modifications to the database structure for
1157          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1158          database is now provided. LDAP attributes now support
1159          eq, pres and sub indexes.
1160         
1161        - Job history now contains additional informations : 
1162          number of copies, filename, title and print options.
1163         
1164    - 1.16alpha10 :
1165       
1166        - Some modifications done to external policy handling.
1167          See sample configuration file for details.
1168   
1169        - Spanish translation added.
1170       
1171    - 1.16alpha9 :
1172   
1173        - mailto can be set to external(...) to warn users above
1174          quota with any command of your choice (e.g. linpopup).
1175          Several parameters are available, see sample configuration
1176          file for details.
1177         
1178    - 1.16alpha8 :
1179   
1180        - Now cupspykota transmits SIGTERMS to the original 
1181          backend when the user deletes a job being processed.
1182

1188        - The CUPS backend is now fully functionnal (it seems).
1189       
1190        - From now on, the use of the pykota filter with CUPS
1191          is deprecated. The pykota filter still has to be
1192          used with LPRng though.
1193       
1194    - 1.16alpha6 :
1195   
1196        - Bug fixed : when edpykota was used to add a printer
1197          with no user or group name, a bad user/group name "*" was
1198          added to the database.
1199         
1200    - 1.16alpha5 :
1201   
1202        - New CUPS backend supports device enumeration !
1203          This means that NO manual CUPS configuration has to
1204          be done. All can now be done from CUPS web interface.
1205       
1206    - 1.16alpha4 :
1207   
1208        - New CUPS backend added.
1209

1231          names or wildcards, separated with commas.
1232         
1233    - 1.15alpha9 :
1234   
1235        - External policy can be used to auto-add unknown users
1236          and any other interesting things you may want to do.
1237          WARNING : You can't auto-add printers for now.
1238          They have to be created manually before.
1239          Look at sample configuration file for examples.
1240         
1241    - 1.15alpha8 :
1242   
1243        - Job history can be disabled if needed.
1244          This feature may be useful for people who use the LDAP
1245          backend and don't want their LDAP tree to grow out of
1246          control.
1247       
1248    - 1.15alpha7 :
1249   
1250        - More work done on caching wrt groups.

1260    - 1.15alpha4 :
1261   
1262        - Problem with Python 2.3 fixed. Needs some definitive
1263          modification.
1264         
1265    - 1.15alpha3 :
1266   
1267        - CGI script now tries to restrict view when the
1268          REMOTE_USER environment variable is set. This allows
1269          people to protect its use with .htaccess files.
1270          When unprotected, or if REMOTE_USER is 'root', then
1271          unrestricted access is granted.
1272          NB : REMOTE_USER is automatically set by the web server
1273          (e.g. Apache) when a page with restricted access is viewed.
1274         
1275    - 1.15alpha2 :
1276

1279        - Outputs a warning if printing system is unknown.
1280       
1281    - 1.15alpha1 :
1282   
1283        - Bug fix in SQL code.
1284       
1285    - 1.14 :
1286   
1287        - The PostgreSQL database connection is now always closed before
1288          exit. The LDAP database connection too, but it didn't suffer
1289          from the problem anyway, AFAICT.
1290       
1291    - 1.14beta2 :
1292   
1293        - An LDAP-specific configuration field was introduced, usermail.
1294          Use it to specify which LDAP attribute contains a valid email
1295          address for the user. See sample configuration file for
1296          details.
1297       
1298    - 1.14beta :
1299   
1300        - Two new LDAP-specific configuration fields were introduced,
1301          newuser and newgroup. Use them to specify if you want to add
1302          quota information to existing entries or elsewhere.
1303          See sample configuration file for details.
1304         
1305    - 1.14alpha9 :
1306   
1307        - Documentation improved.
1308       
1309        - pykotme now also prints the user's account balance value
1310          if the user is registered in the Quota Storage and his
1311          limiting factor is "balance".
1312         
1313    - 1.14alpha8 :
1314   
1315        - bin/waitprinter.sh is now included to wait for
1316          SNMP enabled printers to be idle again before
1317          asking for their internal page counter.
1318          See sample configuration file for details.
1319         
1320    - 1.14alpha7 :
1321   
1322        - edpykota now doesn't check if the user/group is above
1323          quota. The check is only done at print time. This
1324          prevents the sending of email messages when creating
1325          user quotas if quota is already reached at creation
1326          time.
1327         
1328    - 1.14alpha6 :
1329   
1330        - Configuration file split and moved to /etc/pykota/pykota.conf
1331          and /etc/pykota/pykotadmin.conf to prevent simple users to
1332          have Read/Write access to the Quota Database.
1333          Don't forget to :
1334         
1335                $ chmod 640 /etc/pykota/pykotadmin.conf
1336               
1337        - storageuser and storageuserpw configuration fields reintroduced
1338          for the same reason.
1339         
1340        - Code cleaning for future implementation of email addresses
1341          support in the PostgreSQL and LDAP backends.
1342         
1343    - 1.14alpha5 :
1344       
1345        - Big bug fixed when changing the prices for a printer
1346       
1347    - 1.14alpha4 :
1348   
1349        - When adding an user, the user itself and its account balance
1350          are now added in the same LDAP entry. Before they were added
1351          as two different LDAP entries.
1352         
1353    - 1.14alpha3 :
1354   
1355        - Email field added to PostgreSQL database. An upgrade script

1365          balance (below 1.0 by default, configurable) are sent
1366          a warning message.
1367         
1368        - All warning messages to users are now configurable. 
1369          NB : Warning messages to the administrator are not.

1441          hints to the LDAP storage backend.
1442         
1443        - Severe database access optimizations were done by
1444          rewriting most of the Quota Storage backends drivers.
1445

1488          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1489          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1490          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1491          MAILING LIST.
1492         
1493    - 1.08alpha3 :
1494   
1495        - External accounting methods were partly rewritten :
1496         
1497          - No more "broken pipe" should happen.
1498         
1499          - They now take care of the number of copies
1500            This may be unneeded though, if the postscript
1501            file already does this, because this would
1502            overcharge users (number of copies counted
1503            two times). NEEDS MORE TESTING.
1504           
1505          - The sample configuration file now contains 
1506            an external accounting method example which should
1507            work with all DSC compliant Postscript files.
1508           
1509        - Some small bugs were fixed.   
1510       
1511    - 1.08alpha2 :
1512   
1513        - Now works with net-snmp v5.0 and above.
1514          It already worked, but the sample configuration
1515          file didn't contain appropriate values...
1516       
1517    - 1.07 : Release of the Shame !
1518   
1519        - The external accounting methods driver was left out of
1520          the CVS tree. Nobody could use it since it wasn't included !
1521         
1522    - 1.06 :
1523   
1524        - Severe bug fixed : if you had a printer in
1525          power saving state which couldn't answer immediately,
1526          a bug was triggered.
1527          It was caused by a bad copy/paste which
1528          forgot to import a Python module at run time.
1529         
1530    - 1.05 :
1531   
1532        - External accounters are finally available !
1533          This means that you can plug any page accounting
1534          method you like by setting the appropriate
1535          'accounter' field in /etc/pykota.conf
1536          See the sample conf/pykota.conf.sample to
1537          learn how to do.
1538         
1539          NB : Both 'external' and 'stupid' accounting methods
1540               account a job size just before *this* job is
1541               sent to the printer.
1542               The original 'querying' method accounts a job
1543               size just before *the next* job is sent to
1544               the printer.
1545       
1546    - 1.05alpha3 :
1547   
1548        - A 'stupid' and unreliable accounting method was
1549          implemented to serve as an example on how to
1550          do this sort of things. This method only counts
1551          the 'showpage' statements in the input data.
1552          See sample configuration file for details.
1553          Pluggable accounting methods work, but I advise
1554          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1555          It is not reliable enough to be used.
1556          Use the 'querying' accounting method instead.
1557         
1558    - 1.05alpha2 :
1559   
1560        - Pluggable accounting methods.
1561       
1562        - Better error handling.
1563       
1564    - 1.05alpha1 :
1565   
1566        - SECURITY file added to help improve PyKota's security.
1567       
1568        - Extracting the printer's internal page counter is now
1569          tried several times, waiting several seconds between
1570          two tries. This lets the time to warm up for some printers
1571          which don't answer when they are sleeping (my Apple
1572          LaserWriter 16/600 PS is in this case, maybe others too)
1573         
1574        - Small display bug fixed in repykota
1575         
1576    - 1.04 :
1577   
1578        - Default print policy for users/groups unknown from
1579          the print quota system is now DENY instead of ALLOW,
1580          since ALLOW can generate inaccurate results
1581          (incorrect job sizes charged to the wrong persons)
1582         
1583        - LPRng support works !
1584       
1585        - A bug was introduced some time ago wrt printers' default
1586          policy for unknown users. It is now corrected.
1587       
1588        - repykota now displays prices per job and per page for each
1589          printer, if they are defined.
1590         
1591        - Minor display bug fixed in repykota.
1592       
1593        - Problem when running repykota with an empty database was fixed.
1594       
1595    - 1.03 :
1596   
1597        - Upgrade script included for earlier versions.
1598          Please look inside the initscripts subdirectory.
1599          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1600         
1601        - repykota now reports account balances too.
1602       
1603        - PyKota now has a nice logo, see the logos
1604          subdirectory.
1605       
1606        - Manual pages were finally updated.
1607       
1608        - Group quotas seem to work now !
1609       
1610        - The new database schema allows to keep an history of all
1611          jobs as well as charge users per page and/or per job,
1612          and track users' account balance.
1613         
1614        - edpykota now accepts much more command line options to 
1615          use the new functionnalities. See edpykota --help for
1616          details.
1617         
1618        - The installation script now allows to install the sample
1619          configuration file during first installation.
1620         
1621        - More group quota code works, but still not finished. 
1622       
1623        - The CGI script displays a link to PyKota's website.
1624       
1625        - The job history is now kept, this will allow per-period
1626          reports in the future.
1627         
1628        - After having modified the quota for an user with edpykota,
1629          a quota check is done to eventually warn the user/admin about
1630          a quota which is too low to print.
1631         
1632        - A workaround is provided for HP Printers : their internal
1633          page counter is only saved to NVRAM in a 10 increment, so
1634          if you switch them off and then on, the reported page counter
1635          may be lower than the real number of pages printed.
1636          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1637          We unconditionnally set the last job's page count to
1638          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1639          in this case.
1640          For a more accurate accounting, never switch your HP printers
1641          off.
1642         
1643        - A fix is provided for printers which only have a volatile 
1644          page counter (reset to 0 every time you switch the printer on)
1645          This should allow PyKota to work reasonably fine with HP Laserjet
1646          4L/5L/6L, not perfect, but better than nothing.
1647          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1648          For a more accurate accounting, never switch your HP printers
1649          off. This is untested, please report any problem.
1650         
1651        - A bug was fixed when edpykota --add was used with users who already
1652          had a quota on the specified printer.
1653         
1654        - A small display bug in repykota was introduced in preliminary
1655          1.03 versions, and fixed later on.
1656         
1657        - Some minor bugs which happened in rare situations were fixed.
1658       
1659        - Support for AppleTalk printers was added, see sample configuration
1660          file for details.
1661         
1662        - Users and group printing can now be controlled (limited) either by 
1663          print quota or by account balance.
1664       
1665    - 1.02 :
1666   
1667        - The installation script now checks for software availability
1668          and in case a software is missing asks the user if he
1669          wants to continue with the installation or abort it.
1670         
1671        - The configuration file pykota.conf is now expected to be
1672          found in /etc instead of in /etc/cups
1673          The installation script prompts the user to see if he
1674          wants to move an old configuration file to the new location
1675          if needed.
1676         
1677        - Improved documentation.
1678       
1679        - You can now set the tcp/ip port on which the Quota Storage
1680          Server is listening, see sample configuration file for details.
1681       
1682        - Better general error handling.
1683       
1684        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1685          included as well.
1686       
1687    - 1.01 :
1688   
1689        - The configuration file now accepts an option   
1690          to choose the recipient(s) of the email messages :
1691         
1692            - DevNull means no one will receive them.
1693            - User means only the user will receive them.
1694            - Admin means only the admin will receive them.
1695            - Both means the User and the Admin will receive them.
1696           
1697        - The configuration file now uses hard-coded default values
1698          when an option is not set. See sample configuration file
1699          for details.
1700         
1701        - Manual pages are included since 1.00, but I forgot to   
1702          add this information to this file.
1703         
1704        - Redistribution terms for the official package have 
1705          softened and are now fully GPL compatible :
1706          unrestricted modification is now allowed even for
1707          the version number.
1708         
1709    - 1.00 :
1710   
1711        - edpykota now accepts a --noquota option. This
1712          disable quota checking while still doing page
1713          accounting. This is really useful for people
1714          who don't want to limit their users but want
1715          to know how much pages they print.
1716         
1717        - Some untested scripts were added to retrieve
1718          the life time page counter of non-SNMP printers.
1719         
1720        - Every directory now has a specific README file. 
1721       
1722    - 0.99 :
1723   
1724        - Under some circumstances while the user wasn't allowed
1725          to print, he didn't receive any email message. It is
1726          now fixed.
1727         
1728        - When an user wasn't allowed to print, the quota for
1729          the previous user wasn't updated. This is now fixed.
1730         
1731    - 0.98 :
1732   
1733        - Correctly handle the case where the printer is switched off.
1734       
1735        - Small bug wrt syslog fixed.
1736       
1737    - 0.97 :
1738   
1739        - edpykota accepts wildcards on its command line for users/groups too
1740          if the --add option is not set, e.g. :
1741         
1742              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
1743             
1744        - If no user name is passed at all, then a default wildcard of "*"
1745          which means apply the command on ALL users for this printer is used.
1746         
1747        - Small bug fixes.
1748       
1749    - 0.96 :
1750
1751        - Options requester, policy, admin, adminmail and gracedelay can now
1752          be set either globally or per printer. The printer option has
1753          priority if both are defined.
1754
1755        - More powerful configuration parser.
1756       
1757        - If all options are defined globally, there's no need to
1758          define a section for each printer in the configuration
1759          file anymore. Just define a [global] section and it's ok.
1760
1761    - 0.95 :
1762
1763        - External requesters for printers finally added.
1764
1765        - Full internationalization (english and french are supported)
1766 
1767        - More complete quota usage report
1768
1769        - CGI script to access to the quota usage report
1770
1771        - Several bugs fixed.
1772
1773
1774    - 0.9 :
1775
1776        - First public version
