68595a9493 Fix handling of test failures due to uncaught exceptions
We don't just want to exit here, but `longjmp()` back to the conditional
via a call to `DeepState_Fail()`. In doing so, we end up in the common
`DeepState_CatchFail()` branch, which exits with the same nonzero error
code, but also saves the test case if appropriate.

d81cbba137 Clear log stream before failing with longjmp in fatal log
When an assertion fails in the C++ API, it ultimately invokes a
`Fatal`-level `DeepState_Log()`. This calls `DeepState_Fail()`, which
longjmps. If we don't clear the log buffer here, it won't get cleared by
the usual logic which does so. This causes hanging, unflushed log
messages to persist between tests.

This relationship should eventually be inverted and decoupled.

e9bd6dc177 Fixes one or two subtle issues. But the more interesting fix is that I implemented puts in terms of DeepState_Log. Calls to printf that had no format arguments are transformed by the compiler into calls to puts, but that wasn't being wrapped by DeepState, so it was appearing as though those log messages never actually happened. 2017-12-12 14:01:41 -05:00

8248bbdcbc Removed usage of old name, added in a Euler power of like primes example. When the pairwise ASSERT_NEs are absent, you get interesting results that show examples of integer overflows. 2017-12-10 20:08:08 -05:00

c4f74e2389 Adds some error checking around finding important symbols and initializing Manticore/Angr. Adds the ability to save concretized bytes to an output directory. For the time being, I'm going with the approach of the user specifying a output dir, then within that I create directories for each file basename in the tests, and subdirectories for each test name, and in there I put binary test files. 2017-11-02 00:54:18 -04:00

4f914e4eee Fixes to stream formatting of doubles, they weren't being streamed before. Implemented the chk versions of printf and such, so that they all route through the logging interface as well. Implemented the concretization APIs. 2017-11-01 17:56:54 -04:00

d2bc82fc35 Renaming from McTest to DeepState. 2017-11-01 13:38:32 -04:00
Peter Goodman
a46e06b03b Refactored to split common code between Manticore and Angr out into common.py. Implemented the new deferred streaming stuff, it seems to work semi-well for this simple cases I've tested, but there's still work to do. The latest code has some remaining issues. Printing out the final input bytes in Angr shows the wrong thing, although what gets streamed out is right. This is visible when running mctest-angr examples/ArtihmeticProperties. With Manticore, the big issue is that it doesn't properly pickle smt expressions (or something to this effect), so I'm ending up with multiple definitions of the same stuff and that throws exceptions. This is tricky to deal with because the streaming of output needs to be able to save symbolic data. 2017-11-01 02:42:31 -04:00

3702bfcb81 Changed how the logging works to log to a static buffer, then the hooks pull info out from there. 2017-10-30 14:16:02 -04:00

e4f4cfe0db Kind of feature parity between Manticore and Angr on these tests. 2017-10-30 00:45:59 -04:00

4b786adc70 Got Manticore (with some minor unpublished fixes) working for McTest, based on Yan's initial work. Most of the angr code directly ports over, which is convenient. Haven't yet implemented McTest_Log (which isn't working for angr, curiously). 2017-10-29 20:35:50 -04:00
