RiaCurveMerger::addCurveData and RiaWellLogCurveMerger::addCurveData only
validated that the X and Y vectors have the same size with CAF_ASSERT, which is
compiled out in optimized builds. Mismatching sizes are a legitimate run-time
condition for data read from file, so the check has to hold in release builds as
well.
In RiaCurveMerger the shared-X fast path in computeInterpolatedValues() indexes
the Y vector of every curve using the sample count of the first curve. A curve
with identical X values but fewer Y values therefore read past the end of its
heap buffer inside the OpenMP loop. RimEnsembleStatisticsCase passes time steps
and values straight from the summary reader without reconciling the sizes, and
realizations in an ensemble normally share time steps, so this was reachable for
an ensemble containing an ongoing simulation.
Both mergers now truncate the incoming data to the common sample count instead.
For RiaWellLogCurveMerger this is also an improvement in behaviour, since
lookupYValue() used to discard the whole curve when the sizes differed.
Add unit tests covering a single curve with fewer values than time steps and
curves with shared time steps where one curve has fewer values.
Migrate all assert macros in ApplicationLibCode to CAF_ASSERT and remove every
use of cvfAssert.h.
CVF_ASSERT is replaced one to one. CVF_TIGHT_ASSERT is also replaced by
CAF_ASSERT, which is semantically exact: CVF_ENABLE_TIGHT_ASSERTS is 1 only
under _DEBUG, and that is what CAF_ASSERT now does. The two CVF_FAIL_MSG sites
become CAF_ASSERT( false && "message" ), preserving the message with the idiom
already used elsewhere in the code base.
Counts before and after: CVF_ASSERT 1044 to 0, CVF_TIGHT_ASSERT 66 to 0,
CVF_FAIL_MSG 2 to 0, cvfAssert.h references 154 to 0.
Include handling: files that included cvfAssert.h directly now include
cafAssert.h instead, includes left dead by the migration are removed, and files
that were relying on cvfAssert.h transitively get an explicit cafAssert.h. Files
that reach cafAssert.h through another caf header are left unchanged; a missing
include here is a compile error, not a silently disabled assert.
ResultStatisticsCache links only LibCore and therefore had no path to
cafAssert.h. Add the cafPdmCore directory as a private include path rather than
linking the library, since cafAssert.h is header only.
Note that this stops these asserts from firing in Release and RelWithDebInfo,
where CVF_ASSERT was previously active.
