    What's new in GRASS 5.0 beta4 comparing to beta3?

    [GRASS 5 beta4 released Oct. 1999] (Comparing to GRASS 4.x, further implementations up to GRASS 5 beta4)

  • (24bit), r.slope.aspect (calc. of curvature)
  • (import elevation data properly)

  • 121 projections supported now: (m.proj and g.setproj support them as well)

  • 5. Misc:

  • support for cursor key movement in coordinate windows (these screens will be left with <ESC><ENTER> now
  • lots of bugfixes
  • new XDRIVER with true 8..24bit support (choose color depth with d.mon)
  • "configure" tool to create "head" files (compiler instructions) automatically
  • general source code improvement:
  • Better Code:
          - gets() is an Achilles' heel for GRASS when used on the Web, or where
            through ignorance or malice someone can overrun an input buffer. I 
            have replaced gets() calls with the slightly safer fgets(). 
          - G_warning() and G_fatal_error() are called throughout the GRASS code
            tree as though they accepted variable arguments, i.e. 
               G_warning("Oops: error in %s, i = %d\n",string,integer);
            which is not how they were written. They were written to accept one
            char*, which they write to the screen and/or log. I have re-written 
            these functions so that they accept varargs. This change has not
            been approved by anyone, nor passed any peer review. It just seems 
          - G_free() as as companion to G_malloc() and friends. It is annoying
            to have to replace all of the #include <malloc.h> with 
            #include <stdlib.h> so instead I just created a function to be 
            included in the gis.h header. This is portable, which is an 
  • Prototyping:
          - It's much easier to track down the mismatched arguments and implicit
            casts with prototypes. These patches provide prototypes for all of
            the src/libes, and as many other libes and modules as I have gotten
          - In the module code, the 4.2.1v21 patch has automatically-created
            header files to provide function prototypes within each module. Some 
            of this is overkill. As I work through each module, these headers
            are fixed to be a little less intrusive. Right now, though, there 
            are still compile warnings that are the fault of this prototyping.
          - The 5.0 code has not had as much work as the 4.2-series, so there
            are still a number of bad calls lurking in the modules. With the 
            proper prototypes, maybe somebody can fix them. 
  • Bugfixes:
         -  Functions with the wrong number of arguments. 
         -  Functions with the wrong type of arguments. 
         -  Functions with the wrong return type. Usually, this is because a
            function is allowed to default to an 'int' return, even though it 
            returns a char*, or struct*. This may work on 32-bit machines, but 
            whenever sizeof(char*) != sizeof(int) (64-bit machines, for example) 
            these functions overwrite memory, dump cores, and generally fail 
            to work. 
         -  Built-in functions without the proper headers. This leads to bad
            return types.
