cddb6c0e02 Rewrite the zero shortcut tests to avoid dropping a const qualifier. 2014-12-30 20:03:58 +00:00
Dag-Erling Smørgrav
3904e809b2 Add two test cases for shortcut logic used when one operand is zero and 
the other is also the target.

241f524238 Fix a bogus t_malloc_fail in one of the mpi_add_abs() tests. 
Add several subtraction test cases and modify some others to better
exercise the carry logic, which is far more complex for subtraction than
for addition.

Add test cases where the target is the same MPI as one or both operands.

7a90ca7b42 Since X may point to the same MPI as either G or L (or even both), we 
can't set the carry flag based on the contents of G or L after having
modified X.  Instead, compute and stash the new carry value first.

8d0e24dee7 Remove the "trailing garbage" version of the mpi_cmp() test. It would 
be better to systematically pad MPIs used in all tests with garbage.

Greatly expand the number of mpi_cmp() tests to cover all possible
combinations of same or different sign, same or different msb and same
or different magnitude.

f18b915b67 Fix the "x = a + b" allocation failure test. Since a and b were 
equal, mpi_sub_abs() would return early and the test would never
exercise the mpi_grow() call which is intended to fail.
 2014-12-30 16:46:44 +00:00

0d483f20ab Fix msb calculation. We may have to backtrack quite a bit, for 
instance when subtracting two nearly equal large numbers.

2027ce33e7 Add tests for the off-by-one bug we just fixed in mpi_cmp_abs(). 2014-12-30 16:38:47 +00:00

1c024928f9 Fix off-by-one bug in mpi_cmp() which could cause it to read past the 
end of the buffer.

43b870dc83 WIP: implement subtraction correctly. The actual result is now correct 
most of the time, but the MSB calculation is not.

e21452d0c7 Add a few tests for subtraction. They're not particularly well thought 
out, because currently subtraction does not work at all, but they work
well enough in the sense that they fail with the current implementation.

03867777c6 Add numerous tests, mostly for allocation failures and edge conditions. 
Add a t_compare_mpi() predicate which checks that two MPIs have the same
value (but not necessarily the exact same representation).
Clean up and improve existing tests.

7b6b493509 Declare t_malloc_fail_after. 2014-12-29 23:49:50 +00:00
Dag-Erling Smørgrav
3ec87c7a8c Introduce t_malloc_fail_after: if non-zero, it serves as a countdown to 
setting t_malloc_fail.  Also, enforce t_malloc_fail in realloc(), but not
before checking that the argument was valid.

bc8e9d67ba In both mpi_add_abs() and mpi_sub_abs(), make sure that the target is 
untouched if the operation fails.  Also ensure that A = A +/- A works.

98c6349d4a In mpi_zero(), save a memset() if the target is already zero. 2014-12-29 23:22:54 +00:00

1412dac680 Shifting any number by zero places is a no-op, but so is shifting zero by 
any number of places.

8228f19d5a In mpi_copy(), any failure should leave the target untouched. 2014-12-29 23:18:57 +00:00

b2ec312d9f Link each test with only the libraries it needs. This avoids rebuilding 
every single test whenever any of the libraries changes.

889412ec40 Accept a -jN argument which we pass on to gmake. 
Delete all coverage files, not just the root one.
Exit if the tests fail so we can inspect the result.

85defb9929 Fix a cast that discards a const qualifier. 2014-12-29 15:23:52 +00:00
Dag-Erling Smørgrav
82f5c5cf77 In mpi_load(), use be32dec() when possible. 
In mpi_set(), it is impossible for the value being loaded to exceed
the minimum size of an mpi; thus, there is no need for mpi_grow().

7a09b0638f I had forgotten that t_add_test() is actually a printf()-like variadic 
function, which obviates the need for asprintf() in the string comparison
and equality tests.

82e32027af Move the decision of whether to check for memory leaks from the malloc() 
code to the driver and allow an environment variable to override the
default (on unless coverage is enabled).

56eccb99fe Add two utility functions which check if a string contains something that 
can be interpreted as either true or false.  Use this instead of a basic
non-NULL test for the CRYB_PERFTEST check.

559f6c24f7 Fix off-by-one error in TAP output: the test case number was being 
incremented (converted from zero-based to one-based) twice.

eb10ce6d05 If the test case changes desc, it *must* point to an allocated buffer 
which the driver will free after printing the result.

Write test cases for the former.
