22PyKota NEWS :
23
24    - 1.09alpha1 :
25   
26        - More work on LDAP storage backend. Many options
27          were added to /etc/pykota.conf to give some
28          hints to the LDAP storage backend.
29     
30    - 1.08 :
31   
32        - Major bug fix wrt LPRng support for remote jobs.
33       
34        - Major bug fix wrt increase/decrease account balances.
35       
36    - 1.08alpha8 :
37   
38        - Code refactoring.
39       
40        - A single user/password pair is used to connect
41          to the database backend. The storageuser configuration
42          field, and its associated passwords storageuserpw, are
43          not used anymore.
44         
45        - You can now set PyKota in debug mode, see sample configuration 
46          file for details.
47          WARNING : only Quota Storage backend queries are logged in
48          debug mode, for now.
49       
50    - 1.08alpha7 :
51   
52        - Very latest LDAP schema.
53       
54        - Code enhancement wrt easy pluggability of PyKota attributes
55          and object classes into an existing LDAP directory.
56       
57    - 1.08alpha6 :
58   
59        - Minor bug corrections
60       
61        - More work on LDAP : new schema
62       
63    - 1.08alpha5 :
64   
65        - More good work on LDAP storage.
66          repykota now works reasonably well with the sample LDAP directory.
67       
68    - 1.08alpha4 :
69   
70        - LDAP schema included.
71          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
72          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
73          MAY CHANGE IN THE FUTURE. PLEASE TELL US
74          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
75          MAILING LIST.
76         
77    - 1.08alpha3 :
78   
79        - External accounting methods were partly rewritten :
80         
81          - No more "broken pipe" should happen.
82         
83          - They now take care of the number of copies
84            This may be unneeded though, if the postscript
85            file already does this, because this would
86            overcharge users (number of copies counted
87            two times). NEEDS MORE TESTING.
88           
89          - The sample configuration file now contains 
90            an external accounting method example which should
91            work with all DSC compliant Postscript files.
92           
93        - Some small bugs were fixed.   
94       
95    - 1.08alpha2 :
96   
97        - Now works with net-snmp v5.0 and above.
98          It already worked, but the sample configuration
99          file didn't contain appropriate values...
100       
101    - 1.07 : Release of the Shame !
102   
103        - The external accounting methods driver was left out of
104          the CVS tree. Nobody could use it since it wasn't included !
105         
106    - 1.06 :
107   
108        - Severe bug fixed : if you had a printer in
109          power saving state which couldn't answer immediately,
110          a bug was triggered.
111          It was caused by a bad copy/paste which
112          forgot to import a Python module at run time.
113         
114    - 1.05 :
115   
116        - External accounters are finally available !
117          This means that you can plug any page accounting
118          method you like by setting the appropriate
119          'accounter' field in /etc/pykota.conf
120          See the sample conf/pykota.conf.sample to
121          learn how to do.
122         
123          NB : Both 'external' and 'stupid' accounting methods
124               account a job size just before *this* job is
125               sent to the printer.
126               The original 'querying' method accounts a job
127               size just before *the next* job is sent to
128               the printer.
129       
130    - 1.05alpha3 :
131   
132        - A 'stupid' and unreliable accounting method was
133          implemented to serve as an example on how to
134          do this sort of things. This method only counts
135          the 'showpage' statements in the input data.
136          See sample configuration file for details.
137          Pluggable accounting methods work, but I advise
138          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
139          It is not reliable enough to be used.
140          Use the 'querying' accounting method instead.
141         
142    - 1.05alpha2 :
143   
144        - Pluggable accounting methods.
145       
146        - Better error handling.
147       
148    - 1.05alpha1 :
149   
150        - SECURITY file added to help improve PyKota's security.
151       
152        - Extracting the printer's internal page counter is now
153          tried several times, waiting several seconds between
154          two tries. This lets the time to warm up for some printers
155          which don't answer when they are sleeping (my Apple
156          LaserWriter 16/600 PS is in this case, maybe others too)
157         
158        - Small display bug fixed in repykota
159         
160    - 1.04 :
161   
162        - Default print policy for users/groups unknown from
163          the print quota system is now DENY instead of ALLOW,
164          since ALLOW can generate inaccurate results
165          (incorrect job sizes charged to the wrong persons)
166         
167        - LPRng support works !
168       
169        - A bug was introduced some time ago wrt printers' default
170          policy for unknown users. It is now corrected.
171       
172        - repykota now displays prices per job and per page for each
173          printer, if they are defined.
174         
175        - Minor display bug fixed in repykota.
176       
177        - Problem when running repykota with an empty database was fixed.
178       
179    - 1.03 :
180   
181        - Upgrade script included for earlier versions.
182          Please look inside the initscripts subdirectory.
183          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
184         
185        - repykota now reports account balances too.
186       
187        - PyKota now has a nice logo, see the logos
188          subdirectory.
189       
190        - Manual pages were finally updated.
191       
192        - Group quotas seem to work now !
193       
194        - The new database schema allows to keep an history of all
195          jobs as well as charge users per page and/or per job,
196          and track users' account balance.
197         
198        - edpykota now accepts much more command line options to 
199          use the new functionnalities. See edpykota --help for
200          details.
201         
202        - The installation script now allows to install the sample
203          configuration file during first installation.
204         
205        - More group quota code works, but still not finished. 
206       
207        - The CGI script displays a link to PyKota's website.
208       
209        - The job history is now kept, this will allow per-period
210          reports in the future.
211         
212        - After having modified the quota for an user with edpykota,
213          a quota check is done to eventually warn the user/admin about
214          a quota which is too low to print.
215         
216        - A workaround is provided for HP Printers : their internal
217          page counter is only saved to NVRAM in a 10 increment, so
218          if you switch them off and then on, the reported page counter
219          may be lower than the real number of pages printed.
220          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
221          We unconditionnally set the last job's page count to
222          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
223          in this case.
224          For a more accurate accounting, never switch your HP printers
225          off.
226         
227        - A fix is provided for printers which only have a volatile 
228          page counter (reset to 0 every time you switch the printer on)
229          This should allow PyKota to work reasonably fine with HP Laserjet
230          4L/5L/6L, not perfect, but better than nothing.
231          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
232          For a more accurate accounting, never switch your HP printers
233          off. This is untested, please report any problem.
234         
235        - A bug was fixed when edpykota --add was used with users who already
236          had a quota on the specified printer.
237         
238        - A small display bug in repykota was introduced in preliminary
239          1.03 versions, and fixed later on.
240         
241        - Some minor bugs which happened in rare situations were fixed.
242       
243        - Support for AppleTalk printers was added, see sample configuration
244          file for details.
245         
246        - Users and group printing can now be controlled (limited) either by 
247          print quota or by account balance.
248       
249    - 1.02 :
250   
251        - The installation script now checks for software availability
252          and in case a software is missing asks the user if he
253          wants to continue with the installation or abort it.
254         
255        - The configuration file pykota.conf is now expected to be
256          found in /etc instead of in /etc/cups
257          The installation script prompts the user to see if he
258          wants to move an old configuration file to the new location
259          if needed.
260         
261        - Improved documentation.
262       
263        - You can now set the tcp/ip port on which the Quota Storage
264          Server is listening, see sample configuration file for details.
265       
266        - Better general error handling.
267       
268        - Upgrade script for pre 1.01 PostgreSQL database schema is now
269          included as well.
270       
271    - 1.01 :
272   
273        - The configuration file now accepts an option   
274          to choose the recipient(s) of the email messages :
275         
276            - DevNull means no one will receive them.
277            - User means only the user will receive them.
278            - Admin means only the admin will receive them.
279            - Both means the User and the Admin will receive them.
280           
281        - The configuration file now uses hard-coded default values
282          when an option is not set. See sample configuration file
283          for details.
284         
285        - Manual pages are included since 1.00, but I forgot to   
286          add this information to this file.
287         
288        - Redistribution terms for the official package have 
289          softened and are now fully GPL compatible :
290          unrestricted modification is now allowed even for
291          the version number.
292         
293    - 1.00 :
294   
295        - edpykota now accepts a --noquota option. This
296          disable quota checking while still doing page
297          accounting. This is really useful for people
298          who don't want to limit their users but want
299          to know how much pages they print.
300         
301        - Some untested scripts were added to retrieve
302          the life time page counter of non-SNMP printers.
303         
304        - Every directory now has a specific README file. 
305       
306    - 0.99 :
307   
308        - Under some circumstances while the user wasn't allowed
309          to print, he didn't receive any email message. It is
310          now fixed.
311         
312        - When an user wasn't allowed to print, the quota for
313          the previous user wasn't updated. This is now fixed.
314         
315    - 0.98 :
316   
317        - Correctly handle the case where the printer is switched off.
318       
319        - Small bug wrt syslog fixed.
320       
321    - 0.97 :
322   
323        - edpykota accepts wildcards on its command line for users/groups too
324          if the --add option is not set, e.g. :
325         
326              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
327             
328        - If no user name is passed at all, then a default wildcard of "*"
329          which means apply the command on ALL users for this printer is used.
330         
331        - Small bug fixes.
332       
333    - 0.96 :
334
335        - Options requester, policy, admin, adminmail and gracedelay can now
336          be set either globally or per printer. The printer option has
337          priority if both are defined.
338
339        - More powerful configuration parser.
340       
341        - If all options are defined globally, there's no need to
342          define a section for each printer in the configuration
343          file anymore. Just define a [global] section and it's ok.
344
345    - 0.95 :
346
347        - External requesters for printers finally added.
348
349        - Full internationalization (english and french are supported)
350 
351        - More complete quota usage report
352
353        - CGI script to access to the quota usage report
354
355        - Several bugs fixed.
356
357
358    - 0.9 :
359
360        - First public version
