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