| 20 | ============================================================ |
|---|
| 21 | |
|---|
| 22 | TODO, in no particular order : |
|---|
| 23 | |
|---|
| 24 | - Improve the SECURITY document to include good PostgreSQL |
|---|
| 25 | and OpenLDAP default settings. |
|---|
| 26 | |
|---|
| 27 | - Try to talk to education based distribution coordinators |
|---|
| 28 | (SambaEdu, SkoleLinux, K12LTSP, ...) to see how to |
|---|
| 29 | better integrate PyKota with these. |
|---|
| 30 | |
|---|
| 31 | - Write an IPP message parser, and extract the IPP |
|---|
| 32 | billing code, job originating hostname and ipp username |
|---|
| 33 | from job's control files : this would even solve the |
|---|
| 34 | actual page_log parsing problem. |
|---|
| 35 | |
|---|
| 36 | - Allow soft and hard limits to be increased/decreased. |
|---|
| 37 | |
|---|
| 38 | - Better --prototype option in edpykota |
|---|
| 39 | |
|---|
| 40 | - Web enabled pykotme and dumpykota. |
|---|
| 41 | |
|---|
| 42 | - Add a configuration directive to forbid user account |
|---|
| 43 | creation if the user doesn't exist on the system. |
|---|
| 44 | |
|---|
| 45 | - Add an MD5 checksum of the job's datas to the |
|---|
| 46 | history, to be able to discover duplicate print |
|---|
| 47 | jobs. This is partially done : the checksum |
|---|
| 48 | is now computed and exported into the environment |
|---|
| 49 | variable PYKOTAMD5SUM, but it is not yet saved |
|---|
| 50 | into the database. |
|---|
| 51 | |
|---|
| 52 | - Maybe put "gracedelay" in the database. |
|---|
| 53 | |
|---|
| 54 | - Price multiplier/divisor which can be set on a per |
|---|
| 55 | user or per user group basis. |
|---|
| 56 | |
|---|
| 57 | - Ink accounting ala PrintBill. |
|---|
| 58 | |
|---|
| 59 | - Price and statistics per page format. |
|---|
| 60 | |
|---|
| 61 | - Add a description field to users/groups. |
|---|
| 62 | |
|---|
| 63 | - Allow the admin to choose an action to take when the database |
|---|
| 64 | is unavailable (server is down or something like that), so |
|---|
| 65 | introduce two directives : |
|---|
| 66 | |
|---|
| 67 | nodb: accept|reject|hold |
|---|
| 68 | lognodb: /path/to/file/for/later/batch/update/of/database |
|---|
| 69 | |
|---|
| 70 | - CUPS accepts the "STATE: ..." message as backchannel |
|---|
| 71 | data : use this to tell CUPS what action has been taken |
|---|
| 72 | for current job. |
|---|
| 73 | |
|---|
| 74 | - Add frontbanner and rearbanner directives to pykota.conf |
|---|
| 75 | This directives will allow the launch (if executable) |
|---|
| 76 | or the use of the banner path passed as a parameter. |
|---|
| 77 | If executable, the banner content will be taken from |
|---|
| 78 | the command's output, else from the banner file |
|---|
| 79 | directly. |
|---|
| 80 | |
|---|
| 81 | Maybe allow frontbanner: +somepath and |
|---|
| 82 | frontbanner: -somepath |
|---|
| 83 | to allow/deny accounting of the banner itself |
|---|
| 84 | (not sure because may be VERY DIFFICULT !) |
|---|
| 85 | |
|---|
| 86 | Matt Hyclak has sent a patch for cupspykota which seems |
|---|
| 87 | to be ok, but we have to find how to do the same with |
|---|
| 88 | lprngpykota... |
|---|
| 89 | |
|---|
| 90 | - Think about some possible client <=> PyKota dialog |
|---|
| 91 | possibilities, like embedding a small web server in |
|---|
| 92 | PyKota for example, or something like that. |
|---|
| 93 | |
|---|
| 94 | - Log something when --add is used with existing entries. |
|---|
| 95 | Maybe add a new command line option to force/not force |
|---|
| 96 | modification of existing entries. |
|---|
| 97 | |
|---|
| 98 | - Finish implementation of quota-then-balance and |
|---|
| 99 | balance-then-quota. |
|---|
| 100 | |
|---|
| 101 | - Test and document a possible workaround for knowing |
|---|
| 102 | if the job is a banner (embed a postscript comment |
|---|
| 103 | in the banner). |
|---|
| 104 | |
|---|
| 105 | - Introduce the pkusers command. |
|---|
| 106 | pkusers --nogroup |
|---|
| 107 | pkusers --ingroups gr1,gr2,... --outgroups gr3,gr4,... |
|---|
| 108 | |
|---|
| 109 | - Allow the --ingroups command line option to repykota, to |
|---|
| 110 | report only users members of the specified groups. |
|---|
| 111 | |
|---|
| 112 | - Documentation... |
|---|
| 113 | |
|---|
| 114 | - Complete web administrative interface with graphical reports. |
|---|
| 115 | |
|---|
| 116 | - Group administrators (think quotagrpdmins for disk quotas). |
|---|
| 117 | Won't be implemented for now. |
|---|
| 118 | |
|---|
| 119 | - Multidatabase support, e.g. store users in LDAP, quota |
|---|
| 120 | related datas in PostgreSQL, history in text file, |
|---|
| 121 | and so on... For 2.0, probably not before. |
|---|
| 122 | |
