This branch fixes several tests.
I also added some changes that tell users which .db/.dbd file
was missing if the db and filter test programs abort, and
extend the search path so the tests can be run from the test
directory as well as from the O.<arch> directory.
test*() uses printf() so don't print
any results until all results are collected.
On RTEMS/vxWorks buffering of printf() gives
long delays which skew the test results.
Also made additional changes:
* Simplified xRecord.c so it can run on vxWorks.
* Standard way to load DBD and DB files in tests
All test harnesses now run on vxWorks (but some tests still fail).
Move cleanup from event thread to caller.
This handles cases (unit tests) where the task
is never started.
The pexitsem flag serves as the indicatior that
the event task was started.
plugins don't need to inspect more than
field_type, field_size, and no_elements.
In case they do define type=val to prevent
accidental use of uninitialized pointer.
This lets us use epicsParseDouble() for scan rate parsing.
Ensure the scanOnce thread is a higher priority than the fastest
periodic scan thread, irrespective of how many threads there are.
The filter plugins are now in src/std/filters
and their tests in the test subdirectory.
Various portability issues found and fixed:
* Variable declarations after statements in a block
* Code assuming that epicsInt32 = long
* // comments in C files
Removed a number of tests that weren't really tests;
preconditions for future tests that don't actually check
the code being tested should call testAbort() if the
condition fails, which tells the test harness that you
meant to die at that point.
Split up lots of very long source lines.
Probably made a few other changes that I forget about now.
Avoid installing xRecord.dbd. This would otherwise be installed
by the DBDINC.
Also must split out recordtype definition from record instance
definition and run the registrar function between the two loads.
This is due to new sanity checks in the loading process
