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