| 22 | PyKota NEWS : |
|---|
| 23 | |
|---|
| 24 | - 1.03alpha : |
|---|
| 25 | |
|---|
| 26 | - IMPORTANT : DataBase schema has changed. |
|---|
| 27 | DON'T TRY TO UPGRADE AN EXISTING PYKOTA INSTALLATION ! |
|---|
| 28 | The upgrade script will be finalized ASAP, be patient, |
|---|
| 29 | or drop your old quota database to start anew. |
|---|
| 30 | |
|---|
| 31 | - The new database schema allows to keep an history of all |
|---|
| 32 | jobs as well as charge users per page and/or per job, |
|---|
| 33 | and track users' account balance. |
|---|
| 34 | |
|---|
| 35 | - The installation script now allows to install the sample |
|---|
| 36 | configuration file during first installation. |
|---|
| 37 | |
|---|
| 38 | - More group quota code works, but still not finished. |
|---|
| 39 | |
|---|
| 40 | - The CGI script displays a link to PyKota's website. |
|---|
| 41 | |
|---|
| 42 | - The job history is now kept, this will allow per-period |
|---|
| 43 | reports in the future. |
|---|
| 44 | |
|---|
| 45 | - After having modified the quota for an user with edpykota, |
|---|
| 46 | a quota check is done to eventually warn the user/admin about |
|---|
| 47 | a quota which is too low to print. |
|---|
| 48 | |
|---|
| 49 | - A workaround is provided for HP Printers : their internal |
|---|
| 50 | page counter is only saved to NVRAM in a 10 increment, so |
|---|
| 51 | if you switch them off and then on, the reported page counter |
|---|
| 52 | may be lower than the real number of pages printed. |
|---|
| 53 | See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html |
|---|
| 54 | We unconditionnally set the last job's page count to |
|---|
| 55 | abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2)) |
|---|
| 56 | in this case. |
|---|
| 57 | For a more accurate accounting, never switch your HP printers |
|---|
| 58 | off. |
|---|
| 59 | |
|---|
| 60 | - A fix is provided for printers which only have a volatile |
|---|
| 61 | page counter (reset to 0 every time you switch the printer on) |
|---|
| 62 | This should allow PyKota to work reasonably fine with HP Laserjet |
|---|
| 63 | 4L/5L/6L, not perfect, but better than nothing. |
|---|
| 64 | See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html |
|---|
| 65 | For a more accurate accounting, never switch your HP printers |
|---|
| 66 | off. |
|---|
| 67 | |
|---|
| 68 | - A bug was fixed when edpykota --add was used with users who already |
|---|
| 69 | had a quota on the specified printer. |
|---|
| 70 | |
|---|
| 71 | - A small display bug in repykota was introduced in preliminary |
|---|
| 72 | 1.03 versions, and fixed later on. |
|---|
| 73 | |
|---|
| 74 | - Some minor bugs which happened in rare situations were fixed. |
|---|
| 75 | |
|---|
| 76 | - 1.02 : |
|---|
| 77 | |
|---|
| 78 | - The installation script now checks for software availability |
|---|
| 79 | and in case a software is missing asks the user if he |
|---|
| 80 | wants to continue with the installation or abort it. |
|---|
| 81 | |
|---|
| 82 | - The configuration file pykota.conf is now expected to be |
|---|
| 83 | found in /etc instead of in /etc/cups |
|---|
| 84 | The installation script prompts the user to see if he |
|---|
| 85 | wants to move an old configuration file to the new location |
|---|
| 86 | if needed. |
|---|
| 87 | |
|---|
| 88 | - Improved documentation. |
|---|
| 89 | |
|---|
| 90 | - You can now set the tcp/ip port on which the Quota Storage |
|---|
| 91 | Server is listening, see sample configuration file for details. |
|---|
| 92 | |
|---|
| 93 | - Better general error handling. |
|---|
| 94 | |
|---|
| 95 | - Upgrade script for pre 1.01 PostgreSQL database schema is now |
|---|
| 96 | included as well. |
|---|
| 97 | |
|---|
| 98 | - 1.01 : |
|---|
| 99 | |
|---|
| 100 | - The configuration file now accepts an option |
|---|
| 101 | to choose the recipient(s) of the email messages : |
|---|
| 102 | |
|---|
| 103 | - DevNull means no one will receive them. |
|---|
| 104 | - User means only the user will receive them. |
|---|
| 105 | - Admin means only the admin will receive them. |
|---|
| 106 | - Both means the User and the Admin will receive them. |
|---|
| 107 | |
|---|
| 108 | - The configuration file now uses hard-coded default values |
|---|
| 109 | when an option is not set. See sample configuration file |
|---|
| 110 | for details. |
|---|
| 111 | |
|---|
| 112 | - Manual pages are included since 1.00, but I forgot to |
|---|
| 113 | add this information to this file. |
|---|
| 114 | |
|---|
| 115 | - Redistribution terms for the official package have |
|---|
| 116 | softened and are now fully GPL compatible : |
|---|
| 117 | unrestricted modification is now allowed even for |
|---|
| 118 | the version number. |
|---|
| 119 | |
|---|
| 120 | - 1.00 : |
|---|
| 121 | |
|---|
| 122 | - edpykota now accepts a --noquota option. This |
|---|
| 123 | disable quota checking while still doing page |
|---|
| 124 | accounting. This is really useful for people |
|---|
| 125 | who don't want to limit their users but want |
|---|
| 126 | to know how much pages they print. |
|---|
| 127 | |
|---|
| 128 | - Some untested scripts were added to retrieve |
|---|
| 129 | the life time page counter of non-SNMP printers. |
|---|
| 130 | |
|---|
| 131 | - Every directory now has a specific README file. |
|---|
| 132 | |
|---|
| 133 | - 0.99 : |
|---|
| 134 | |
|---|
| 135 | - Under some circumstances while the user wasn't allowed |
|---|
| 136 | to print, he didn't receive any email message. It is |
|---|
| 137 | now fixed. |
|---|
| 138 | |
|---|
| 139 | - When an user wasn't allowed to print, the quota for |
|---|
| 140 | the previous user wasn't updated. This is now fixed. |
|---|
| 141 | |
|---|
| 142 | - 0.98 : |
|---|
| 143 | |
|---|
| 144 | - Correctly handle the case where the printer is switched off. |
|---|
| 145 | |
|---|
| 146 | - Small bug wrt syslog fixed. |
|---|
| 147 | |
|---|
| 148 | - 0.97 : |
|---|
| 149 | |
|---|
| 150 | - edpykota accepts wildcards on its command line for users/groups too |
|---|
| 151 | if the --add option is not set, e.g. : |
|---|
| 152 | |
|---|
| 153 | $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*" |
|---|
| 154 | |
|---|
| 155 | - If no user name is passed at all, then a default wildcard of "*" |
|---|
| 156 | which means apply the command on ALL users for this printer is used. |
|---|
| 157 | |
|---|
| 158 | - Small bug fixes. |
|---|
| 159 | |
|---|
| 160 | - 0.96 : |
|---|
| 161 | |
|---|
| 162 | - Options requester, policy, admin, adminmail and gracedelay can now |
|---|
| 163 | be set either globally or per printer. The printer option has |
|---|
| 164 | priority if both are defined. |
|---|
| 165 | |
|---|
| 166 | - More powerful configuration parser. |
|---|
| 167 | |
|---|
| 168 | - If all options are defined globally, there's no need to |
|---|
| 169 | define a section for each printer in the configuration |
|---|
| 170 | file anymore. Just define a [global] section and it's ok. |
|---|
| 171 | |
|---|
| 172 | - 0.95 : |
|---|
| 173 | |
|---|
| 174 | - External requesters for printers finally added. |

|---|
| 181 | |

|---|
| 183 | |
|---|
| 184 | |
|---|
| 185 | - 0.9 : |
|---|
| 186 | |
|---|
