Key:

*-An important Item that needs to be finished

B-Initial of person who needs to fix this (Binki)

M-LordofWar needs to fix this

E-normaldotcom needs to fix this

x-finished task

=-Long-term goal

?-needs reconsideration/explanation/rewording

Notes:

  Initial release will no longer feature SSH auth, distrend will handle auth telnet-style. User registration will be done via PHP.

Build

General

=-documenation: manpages

Master

*-Complete testing with interactive test mode

 -update frame assigner to distribute some frames for lower-priority jobs when there's a higher priority job

?-make frame assigner not assign frames beyond the amount of frames in a single job

B-Add calls to remotio -> make API for sending messages ~= a function for every type of message defined in protocol.h

 -Write a stub for getting info from the tarball/validifying the tarball. Read distren-job.xml, a file in the tarball, to find out 1. which rendering system to use (that system, e.g. blender/povray, can read more specifics, such as name of file to pass to blender and frames. Options common between different systems will be handled in common as best as possible)

 -Write a stub for publishing file and constructing job description so that the job can be shared

*-Other XML-writing/reading such as current stats / jobs / data / etc, xml writing for job creation, ...

=-XML-RPC cgi interface for obtaining info

=-charsets: the program should operate in UTF-8. This is partially required by libxml2's (and XML's) usage of UTF-8. We want the program's internal charset to be UTF-8 and figure out if we need w_char/whatever to fulfill UTF-8. I don't believe we do... mabye we just need a declaration that al data stored must be in UTF-8 format. -> we need to consider how charsets work when and if issues come up

M-explain members of struct general_info; e.g., what is timestamp used for, what's the point of the hibernate var, etc.

Slave

 -Fix current bugs

*-Currently distrencommon.conf is not created slave-side

*-Add calls to remoteio, once it works or even before it works -> write message API functions and API

=-Make code more flexible for different types of jobs and operating systems (such as paths, libs, etc)

=-Add code to allow pausing/resuming of the slave (including a running blender process) -> signal handling (SIGTSTP vs. SIGSTOP), distrenslave_control cmdline interface

B-Add tmpdir variable (just like the datadir variable) that is compile-time or whatever -> simple API to allow configuration-file override while taking into account defaults set by ./configure

*-Finish stub to delete old job data and output

=-Upload finished frames' output files while rendering subsequent frames

Options

=-Rewrite some stuff, try to make it simpler

x-Move server and client confuse code into their individual files, rather than in the common file. -- note: there wasn't any client code in options.c. There was the ``server'' section. That section is passed multiple times and provides information to remoteio on how to connect to servers
