| 20 | ============================================================ |
|---|
| 21 | |
|---|
| 22 | TODO, in no particular order : |
|---|
| 23 | |
|---|
| 24 | - Ensures that all special characters in strings are properly |
|---|
| 25 | escaped when dumping datas : quotes, xml entities, etc... |
|---|
| 26 | |
|---|
| 27 | - Add date filtering options to dumpykota, something like |
|---|
| 28 | date=+20050101 date=-20050201 |
|---|
| 29 | to dump all jobs printed between January 1st 2005 included |
|---|
| 30 | and February 1st 2005 not included. This looks ugly but |
|---|
| 31 | at least we avoid the problematic '<' and '>' on command |
|---|
| 32 | lines, which would mandate the use of quotes... |
|---|
| 33 | |
|---|
| 34 | - Make the PyKota's logo URL a new configuration directive. |
|---|
| 35 | |
|---|
| 36 | - Pass-through mode for printers : history correctly filled (including |
|---|
| 37 | job size) but no impact on user's page counter or account |
|---|
| 38 | balance : this is meant to be a temporary situation for |
|---|
| 39 | a printer to be in pass-through mode, for example during |
|---|
| 40 | an exam where the faculty pays for the printouts and we |
|---|
| 41 | don't want our users to complain about their credits being |
|---|
| 42 | "eaten" for mandatory printouts. |
|---|
| 43 | |
|---|
| 44 | - Allow several levels of administrative priviledges by allowing |
|---|
| 45 | files like ~pykota/pykotadmin.someusername.conf (readonly by |
|---|
| 46 | user 'someusername'), and have the database server deal |
|---|
| 47 | with the permissions : no need for additionnal code or data |
|---|
| 48 | in PyKota's database ! |
|---|
| 49 | |
|---|
| 50 | - Add a "printing denied" indicator on user print quota entries, |
|---|
| 51 | to temporarily forbid an user to print on a particular printer. |
|---|
| 52 | |
|---|
| 53 | - Maybe per user "denyduplicates" : my 5 years old daughter |
|---|
| 54 | just prints again when the printer is off... |
|---|
| 55 | |
|---|
| 56 | - Now that the job size is ALWAYS precomputed, add a |
|---|
| 57 | MaxJobSize attribute to users and groups (printers as |
|---|
| 58 | well, maybe ?) to limit each job's size if needed. |
|---|
| 59 | |
|---|
| 60 | - Add precomputed job size (and price) to the history for |
|---|
| 61 | controlling purpose. |
|---|
| 62 | |
|---|
| 63 | - Try to talk to education based distribution coordinators |
|---|
| 64 | (SambaEdu, SkoleLinux, K12LTSP, ...) to see how to |
|---|
| 65 | better integrate PyKota with these. |
|---|
| 66 | |
|---|
| 67 | - Allow soft and hard limits to be increased/decreased. |
|---|
| 68 | |
|---|
| 69 | - Add most configuration directives to the database itself, |
|---|
| 70 | while still allowing to overwrite them with the configuration |
|---|
| 71 | files at run time. |
|---|
| 72 | |
|---|
| 73 | - Ink accounting ala PrintBill. |
|---|
| 74 | |
|---|
| 75 | - Price and statistics per page format. |
|---|
| 76 | |
|---|
| 77 | - Add a description field to users/groups. |
|---|
| 78 | |
|---|
| 79 | - Allow the admin to choose an action to take when the database |
|---|
| 80 | is unavailable (server is down or something like that), so |
|---|
| 81 | introduce two directives : |
|---|
| 82 | |
|---|
| 83 | nodb: accept|reject|hold |
|---|
| 84 | lognodb: /path/to/file/for/later/batch/update/of/database |
|---|
| 85 | |
|---|
| 86 | - CUPS accepts the "STATE: ..." message as backchannel |
|---|
| 87 | data : use this to tell CUPS what action has been taken |
|---|
| 88 | for current job. I did some testing but wasn't able to |
|---|
| 89 | make it work... |
|---|
| 90 | |
|---|
| 91 | - Think about some possible client <=> PyKota dialog |
|---|
| 92 | possibilities, like embedding a small web server in |
|---|
| 93 | PyKota for example, or something like that. |
|---|
| 94 | |
|---|
| 95 | - Log something when --add is used with existing entries. |
|---|
| 96 | Maybe add a new command line option to force/not force |
|---|
| 97 | modification of existing entries. |
|---|
| 98 | |
|---|
| 99 | - Finish implementation of quota-then-balance and |
|---|
| 100 | balance-then-quota. |
|---|
| 101 | |
|---|
| 102 | - Introduce the pkusers command. |
|---|
| 103 | pkusers --nogroup |
|---|
| 104 | pkusers --ingroups gr1,gr2,... --outgroups gr3,gr4,... |
|---|
| 105 | |
|---|
| 106 | - Allow the --ingroups command line option to repykota, to |
|---|
| 107 | report only users members of the specified groups. |
|---|
| 108 | |
|---|
| 109 | - Documentation... |
|---|
| 110 | |
|---|
| 111 | - Learn more bits of PHP to help with phpPyKotaAdmin, which |
|---|
| 112 | is a GREAT tool ! |
|---|
| 113 | |
|---|
| 114 | - Multidatabase support, e.g. store users in LDAP, quota |
|---|
| 115 | related datas in PostgreSQL, history in text file, |
|---|
| 116 | and so on... For 2.0, probably not before. |
|---|
| 117 | |
