- Added new test/test_suite.in with list of regression and unit tests
previously in Makefile.am, to be shared between Unix and Windows
builds.
- Updated regression.cc & unit.cc to return the number of failed tests
to indicate to CTest that the test failed. Similarly, a crash or
unhandled exception terminates the process with a non-zero exit code.
- This change doesn't affect running the tests with autotest in Unix
builds because this processes test output from custom-test-driver &
test-suite.sh, and ignores the exit code of the test runner.
- Removed comment in test/test-cases/regression-offset-variable.json as
this is not supported by JSON and prevents strict parsers to read and
process the file.
- Minor change in regression.cc's clearAuditLog to replace std::ifstream
with std::ofstream as the mode to open the flag applies to an output
stream.
- Minor change in unit.cc to simplify code that deletes tests.
- Minor changes to test/custom-test-driver to correct usage information.
This commit fixes quite a few odd things in regex code:
* Lack of encapsulation.
* Non-method functions for matching without retrieving all groups.
* Regex class being copyable without proper copy-constructor (potential UAF
and double free due to pointer members m_pc and m_pce).
* Redundant SMatch::m_length, which always equals to match.size() anyway.
* Weird SMatch::size_ member which is initialized only by one of the three matching
functions, and equals to the return value of that function anyways.
* Several places in code having std::string value instead of reference.
C++ regex library proven to be unusable for gcc 4.8 and earlier version, so
reimplement code using PCRE library in order to build workable version of
unit_test executable for CentOS 7, RHEL 7, Ubuntu 14 and SUSE Linux 12.
