Ah, thinking about it doesn't dbLoadTemplate do the same (write to stdout,
and errors to stderr), I have this in a tcl catch { exec ...} call which
detects anything being written to stdout, so perhaps the problem is that the
error is not being detected by msi ???  as a test I added a ";" to a
template file (one of our most common errors).  dbLoadTemplate seems to
catch this msi not.


msi is more generic than dbLoadTemplates and thus doesn't report the same errors that dbLoadTemplate reported.

I will also suggest is that what is required is something that checks that dbLoadDatabase will work on the file created by msi.

base has a test routine that could be used. It is located at <base>/src/dbStatic/dbReadTest.c. It calls dbLoadDatabase for selected files and reports errors if dbLoadDatabase fails and reports nothing if dbLoadDatabase succeeds.

Examples: This should work with any version of base

cd <base>/bin/<arch>

Then create two files

test.db
record(ai,"test")
{
}

test1.db
record(ai,"test")
{
    field(SCAN,"1 second")
}
record(ai,"test1")
{
    field(JUNK,"xxxx")
}



Then the following happens

mercury% dbReadTest
usage: dbReadTest -Idir -Smacsub file.dbd file.db
mercury%

This is just to show what dbReadTest accepts as input.

mercury% dbReadTest -I ../../dbd ../../dbd/base.dbd ./test.db
mercury%

Since test.db was a valid file dbReadTest reported nothing.

mercury% dbReadTest -I ../../dbd ../../dbd/base.dbd ./test1.db
Error filename="../dbLexRoutines.c" line number=899
Field Not Found
  Last token ")"
input line:     field(JUNK,"xxxx")
   in: file ./test1.db line 7

db_parse returned -1
For input file ./test1.dbfilename="../dbReadTest.c" line number=77
from dbReadDatabase
mercury%



Thus it reported an error.

I suspect you will want to start with dbReadTest and produce something more compatible with your requirement.
