also note, this routine this routine does NOT use the BCD2_*
|

|
routines. As a result, it WILL fail if the keys being deleted

exceed 32 bits. Since this would require ~660 update iterations,
|
||
|
|
this seems an acceptable oversight

This is the revised data generator for DSS.
|
||
|
|
|
||
|
|
The rewrite tried to accomplish three things:
|
||
|
|
<ol>
|
||
|
|
<li>identify and isolate
|
||
|
|
all the implicit assumptions about limits, bounds, ranges, distributions, etc.;
|
||
|
|
<li>standardize the way any given table was generated/
|
||
|
|
printed to ease understanding and maintenance;
|
||
|
|
<li>bring the generator
|
||
|
|
in line with the current work of the committee and the excellent spec
|
||
|
|
the Indira put together;
|
||
|
|
<li> provide an easy way to adjust distributions, string contents and to facilitate experimentation to get a
|
||
|
|
better idea of the impact of data population changes.

Running make will create an executable (using the compiler flags in
|
||
|
|
CFLAGS, the ld flags in LDFLAGS and the libraries in LIBS [-O, -s,
|
||
|
|
and -lm by default]) which will create flat files suitable for dbload.
