Joe Ranweiler 691cf24108 Remove usage of old internal globals 
- Use `DeepState_CurrentTestRun` global shared struct
- Allocate memory for the above in `DeepState_Setup()`
- Update `DeepState_Catch...` functions to map enums to status ints
 2018-02-21 19:22:20 -08:00
Joe Ranweiler f07fd1cab7 Split up mapping and init of current test run globals 
- Use `DeepState_AllocCurrentTestRun()` to map memory in take-over setup
- Add error handling for `mmap()` call
- Unify init of test globals via `DeepState_InitCurrentTestRun()`
 2018-02-21 19:09:01 -08:00
Joe Ranweiler 4f711da986 Use DeepState_CurrentTestRun in take-over test case replays 
- Map shared memory for `DeepState_CurrentTestRun`
- For non-crashing forked test runs, inspect the above to figure out
  what happened. In particular, this supports `CHECK` and soft failures.
 2018-02-21 18:52:23 -08:00
Joe Ranweiler d4dc9eaa01 Add struct for info about single test runs, update in global setters 
Instead of exit codes, we will use the global instance of this (shared
with a parent process) to determine the result of forked test runs.

Joe Ranweiler 9d47f21f5a Hide mutation of test globals behind internal functions 2018-02-21 17:17:43 -08:00

Joe Ranweiler c09feec114 Call DeepState_Begin() for each forked take-over test case 2018-02-20 15:52:14 -08:00
Joe Ranweiler 23dbbbdc57 Log all test run result cases in native take-over 
Warning: this does not work correctly with tests that soft fail, e.g.
via a `CHECK` assertion. This is because the soft failures only update
the child's `DeepState_TestFailed` global variable, but do not exit.
What we will soon do is share memory with the child process, and derive
the "test result" from that shared memeory.

Joe Ranweiler a81f816d89 If in take-over mode, exit on fatal error 
In take-over mode, the "test" is the entire binary being executed as a
child process. So, we want to exit, rather than trying to `longjmp()` to
`DeepState_ReturnToRun`, which was never initialized.
 2018-02-20 15:43:34 -08:00
Joe Ranweiler 065c97c2c0 Add --take_over flag to native binaries 2018-02-20 15:43:34 -08:00

Joe Ranweiler 93a95b0e96 Use native fake test and file name that matches executors 2018-02-20 15:43:34 -08:00
Joe Ranweiler 45fcfe0921 Add DeepState_TakeOver() interface 2018-02-20 10:31:29 -08:00
Joe Ranweiler 23af5b562d Add DeepState_Crash() hook 2018-02-14 12:22:38 -08:00
Joe Ranweiler ac7e57a833 Consistently stub test case save hooks 2018-02-14 10:24:15 -08:00
Joe Ranweiler ab43f75361 Add hook to save crashing tests 2018-02-14 10:24:15 -08:00
Joe Ranweiler 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.

Joe Ranweiler dd8a1c6608 Use external linkage for global input buffer 
This is to support running saved auto-generated test cases.

Joe Ranweiler c6eca451c5 Fix flag decl and defs 2018-02-08 14:16:16 -08:00
Peter Goodman 1aa468dabc Minor formatting changes. 2018-02-06 12:18:06 +08:00
Peter Goodman 2eaeb7480c Adding Google Flags-like command-line option parsing, though implemented in C, to the main executable. The code is ported from Granary2. 2018-01-07 16:25:31 -05:00
Peter Goodman 622afcdb98 Made variadic argument lists work in 32 bit x86. 2017-12-13 23:53:48 -05:00
Peter Goodman 1433f34960 Makeing 100% sure that the format_bufs are NUL-terminated. 2017-12-13 22:46:20 -05:00
Peter Goodman 7c585f5c44 Add 32-bit support, i.e. libdeepstate32 2017-12-13 21:53:33 -05:00
Peter Goodman f4dd61f895 Added overrides for assert_fail and stack_chk_fail. 2017-12-13 14:16:21 -05:00
Peter Goodman 308fe70eb6 Hooked __assert_fail into the logging system. 2017-12-13 12:43:34 -05:00
Peter Goodman 5a84f665b6 Minor tweak. 2017-12-13 01:31:29 -05:00
Peter Goodman 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
Peter Goodman 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
Peter Goodman fcd000dc14 Added a maximize objective API to DeepState. 2017-12-10 13:37:47 -05:00
Peter Goodman 188d4517d8 Added prime polynomial example, new Pumping function to address scalability challenges with primality testing, and some improvements to the streaming interface, where if you don't stream in values, then the python side doesn't end up printing out some 'empty' stream infos. 2017-12-09 16:43:43 -05:00
Peter Goodman f9fb7e81be Initial progress in Issue #7 with support for a Dr. Fuzz harness. 2017-12-08 21:07:52 -05:00
