| 20 | ============================================================ |
|---|
| 21 | |
|---|
| 22 | TODO, in no particular order : |
|---|
| 23 | |
|---|
| 24 | - Add a third settable price for printers : a minimal cost |
|---|
| 25 | for a page, with a default value of 0.0. The value would |
|---|
| 26 | be used instead of the computed price in the case of ink |
|---|
| 27 | accounting if the computed price would be lower than this |
|---|
| 28 | minimal price. The value wouldn't be used (yet?) for |
|---|
| 29 | normal page accounting. |
|---|
| 30 | |
|---|
| 31 | - Allow for configurable setting wrt the fact that PyKota waits |
|---|
| 32 | for the printer being idle before asking for printer's internal |
|---|
| 33 | page counter before sending any data to the printer : if |
|---|
| 34 | the print server is correctly configured (i.e. only PyKota can |
|---|
| 35 | access to this particular printer), then we know for sure the |
|---|
| 36 | printer will be idle at this time, because we wait for it |
|---|
| 37 | to become idle again after having printed the job => we could |
|---|
| 38 | save up to 50% of waiting time, and handle more jobs |
|---|
| 39 | in the same time. |
|---|
| 40 | |
|---|
| 41 | - --orderby and --order ASC|DESC for dumpykota (or --asc | --desc) |
|---|
| 42 | |
|---|
| 43 | - Document the PYKOTA_HOME environment variable. |
|---|
| 44 | |
|---|
| 45 | - LDAP : See if setting cn=ThePrinter for user print quota entries |
|---|
| 46 | could be done, only in the case where userquotabase=user |
|---|
| 47 | (idem for groups). Would make direct modifications (e.g. |
|---|
| 48 | with gq) more easy. |
|---|
| 49 | |
|---|
| 50 | - Allow the disabling of an user print quota entry without |
|---|
| 51 | deleting it. |
|---|
| 52 | |
|---|
| 53 | - Store the value of the user's account balance in the |
|---|
| 54 | printing history (the value at the time of printing) |
|---|
| 55 | as well as in the payments history (as a safety check |
|---|
| 56 | in case an user complains). |
|---|
| 57 | |
|---|
| 58 | - PJL for non-networked backends (see ML's history) |
|---|
| 59 | |
|---|
| 60 | - Add the listing of the member printers in pkprinters if the printer |
|---|
| 61 | is a printer group. |
|---|
| 62 | |
|---|
| 63 | - Allow several levels of administrative priviledges by allowing |
|---|
| 64 | files like ~pykota/pykotadmin.someusername.conf (readonly by |
|---|
| 65 | user 'someusername'), and have the database server deal |
|---|
| 66 | with the permissions : no need for additionnal code or data |
|---|
| 67 | in PyKota's database ! |
|---|
| 68 | |
|---|
| 69 | - Try to talk to education based distribution coordinators |
|---|
| 70 | (SambaEdu, SkoleLinux, K12LTSP, ...) to see how to |
|---|
| 71 | better integrate PyKota with these. |
|---|
| 72 | |
|---|
| 73 | - Add most configuration directives to the database itself, |
|---|
| 74 | while still allowing to overwrite them with the configuration |
|---|
| 75 | files at run time. |
|---|
| 76 | |
|---|
| 77 | - Price and statistics per page format. |
|---|
| 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 | - Documentation... |
|---|
| 92 | |
|---|
| 93 | - Learn more bits of PHP to help with phpPyKotaAdmin, which |
|---|
| 94 | is a GREAT tool ! |
|---|
| 95 | |
|---|
| 96 | - Multidatabase support, e.g. store users in LDAP, quota |
|---|
| 97 | related datas in PostgreSQL, history in text file, |
|---|
| 98 | and so on... For 2.0, probably not before. |
|---|
| 99 | |
|---|
| 100 | - Re-add support for LPRng if interest is high enough (it is |
|---|
| 101 | not for now) |
|---|
| 102 | |
|---|
