Known bugs in current GRASS GIS version 5.0 CVS
[In sync with GRASS 5.0 beta CVS version]

Maintained by

Please send a note if detecting an unknown bug:

Bugs being release-critical with regard to GRASS 5.0stable release 
are indicated [RC].

[RC] CELL-Driver: 
  -colors are not correct
   Comment from Carl Anderson <candrsn@mindspring.com>
    Tracking of the "bug" will have to start in
    src/display/d.rast/cmd/display.c
    Since GRASS4 did the colors right, using both GRASS4 and GRASS5
    drivers, I suspect one of the Libraries and not the XDRIVER.
    look at D_set_colors ().
    (being worked on by ?)
  - When plotting to D_CELL, the color black is changed to white. this
    concerns vector maps, fonts (in d.legend), grid an d.erase. I think this
    problem did not exist in version 5b10.
    reported by: Reinhard Brunzema <r.brunzema@web.de>)

----------- libraries ---------------------------------------------

- GRASS raster colors bug:
  GRASS becomes extremely slow in case more than 8000 colors are within
  a raster map (therefore color quantization in r.in.tiff etc).
   (being worked on by ?)

----------- modules ---------------------------------------------

d.param.scale (at src.nonGPL/display/d.param.scale/)
 - replace numerical recipes functions with src/libes/gmath/ functions
 - lower axis description not readable
 - sometimes "floating point exeption", especially in par=geary
   (being worked on by ?)

-----------------------------------------------------------------------
Modules with interface problems (parser etc): 
-----------------------------------------------------------------------
(collected by Andreas Lange, not release critical, bu should be fixed
 sometimes for consistency)

--------------- script used --------------------                                
cd $GISBASE/bin                                                                 
for f in ?.*; do echo '---> '$f; $f -help; done 2>&1 | more                     
------------------------------------------------- 

d.vect.pg, d.what.r.pg, d.what.s.pg, d.what.v.pg,        
g.column.pg, g.stats.pg, g.table.pg, v.reclass.pg print :                
 Please run g.select.pg to identify a current database.      

g3.region:
  no parser

i.tape.tm.fast:
  ERROR (only for xy-locations), no "Usage: " Info

m.in.stf1.tape:
 must be run in command mode only (USAGE:) ... no parser interface

v.in.arc.pg -help prints :
 Coverage type:
Enter "polygon(area)" or "line"
Hit RETURN to cancel.

v.in.dlg: 
  ????

m.lulc.USGS -help prints :
Cannot open USGS CTG file

tcltkgrass launch itself, ignoring the -help option...

All interactive functions print only:
Usage : <name of the command>
  (This command must be run interactively)

On the other hand, some help messages are huge (75 lines...)

Sometimes, a blank line is printed before the "Usage:" string 
this is also not consistent...

 - Comments on updating 4.x vector modules to 5.x vector:
   There is a slightly modified category support:

  Comment on vector cats from Bill Hughes:
  The Categories structure was changed between 4.x and 5.0beta.
  The change seems to have moved the *labels element out of the list
  structure and replace list.num with the index to **labels.  The fix
  is to change the SCS/* code to use 'cats->labels[i]' instead of
  'cats->list[i].labels'  There will be breakage around 'list[i].num'
  as well, and probably these can be deleted, or use 'cats->num' instead.
  The cats.count is cats.ncats now (see src/include/gis.h).

  ->Note:  All vector modules should be updated
