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
 
~-Cancelled goal
 
a-Goal needing assessment
 
?-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.
 
  Simpleslave uses a PHP API to communicate with the mysql-backed server, allowing debugging while server software is nonfunctional.
 

	
 
Build
 

	
 
General
 
  =-documenation: manpages
 
  =-runtime support: should we eventually just go with APR, glib, maybe something from suckless people? Is libdaemon (or whatever's out there) useful?
 
  =-XML (XML-RPC): useful as a communication protocol? as RPC protocol? see atheme; useful as job description format possibly.
 
  B-remoteio: figure out how to handle communications; async + callbacks seems the best method to me atm
 

	
 
Master
 
  B/E/?-Add calls to remotio -> make API for sending messages ~= a function for every type of message defined in protocol.h (are SendSignal() and SendExtSignal() good enough?)
 
  a-XML-RPC 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
 
  *-figure out delete-during-traversal with liblist
 
  *-after job is complete and verified by the user, tar frames for easy download
 
 
 
  x-Complete testing with interactive test mode
 
  x-Complete DB testing with php server workaround
 
  x-resolve conflict between liblist and libmysqlclient
 
  x-update frame assigner to distribute some frames for lower-priority jobs when there's a higher priority job (Ask LordOfWar if this is implemented in sprocs already(it is))
 

	
 

	
 
Slave
 
  B-UnpackJob() and supporting functions need to work
 
  E-Restore tar functionality after unpackJob() is functional
 
  E-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
 
  E-Add error checking and cleaner recursive deletion to delete_jobdata
 
  =-Upload finished frames' output files while rendering subsequent frames
 

	
 
  x=Add lockout of slaves below a certain version
 
  x-Add simpleslave with code to work around nonexisting server codebase
 
  x-Backport SimpleSlave functionality to slave code
 
  x-Restore tar functionality after unpackJob() is functional (6/26/10: unpackJob isn't functional, but tar re-implemented)
 

	
 

	
 

	
 
Options
 
  B-Push patch for relative includes in confuse to the confuse developers -- windows/mingw32 testing required first
 
  ?-Expand execio() to support stderr
 
  =-Rewrite some stuff, try to make it simpler
 
  =-Review all confuse interfacing
 

	
 
  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
 

	
 
WebInterface
 
  *-Tarball validation and other checks
 
  *-Scale images on web interface, imagemagick?
 
  *-Add "stop" button functionality and other missing button functionality
 
  E-Check queries and output for all edit scripts, e.g., edit profile userlevel dropdown doesn't show the user's current userlevel
 
  E-Simplify web interface, make it more lightweight
 
  E-Make some icons for deleting/editing/etc that aren't horribly ugly
 
  E-Get rid of "My Output" or move some functionality to this area
 
  =-Allow "archiving" of jobs?
 
  =-Begin working on MeshLib seamless integration with DistRen
 
  =-Create install.php to guide through database connection and schema deployment
 
  =-Add feature to "purchase" priority with Render_Points
 

	
 
Overall
 
  *-Output type is currently a placeholder option at this point, make it actually affect the output
 
  *-Change the way the database handles storage of paths to frame data (path + extension?)
 
  *-Output resolution is currently a placeholder option, make it actually affect the output
