- The previous approach would create a std::unique_ptr and store it in
a std::list in VariableValue (Origins)
- The new approach now stores Origins in a std::vector and constructs
VariableOrigin elements in-place on insertion.
- Instead of having two heap-allocations for every added VariableOrigin
instance, this performs only one.
- If multiple origins are added, std::vector's growth strategy may even
prevent a heap-allocation. There's a cost on growing the size of the
vector, because a copy of current elements will be necessary.
- Introduced reserveOrigin method to notify that multiple insertions
will be made, so that we can use std::vector's reserve and do a
single allocation (and copy of previous elements), and then just
initialize the new elements in-place.
- Added support to build 32-bit versions of libModSecurity on Linux
- Added support to build libModSecurity using clang on Linux (both
64-bit and 32-bit versions)
- Fixed macOS dependencies to include yajl, not only because it is
a required dependency, but because tests were not being run on
macOS builds without it.
- Added build 'without libxml' to Linux & macOS configurations.
- Added build 'without ssdeep' to Linux configurations (already in macOS
configuration)
- Added build 'with lmdb' to Linux & macOS configurations, replacing the
existing one 'without lmdb' because by default LMDB is disabled if not
explicitly turn on in configure.
- Removed 'without yajl' build because it's a required 3rd party
dependency.
- Added bison & flex dependencies to enable parser generation.
- The parser is not used interactively so we can avoid including
unistd.h, which is not available on Windows MSVC C++ compiler.
- The #ifdef WIN32 introduced in PR #3132 would probably be overwritten
when the parser is updated.
- By default, all the 3rd party dependencies are enabled.
- A dependency can be turned off by adding the "-DWITHOUT_xxx=ON" to
the call of vcbuild.bat
- List of 3rd party dependencies and associated option to turn them off:
- LMDB: WITHOUT_LMDB
- LUA: WITHOUT_LUA
- LibXML2: WITHOUT_LIBXML2
- MaxMind: WITHOUT_MAXMIND
- cURL: WITHOUT_CURL
- 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.
- Addresses SonarCloud issue cpp:S5025 (Memory should not be managed manually)
- This function was not changed for the Windows port, but a similar
change to the one suggested was done in expandEnv in the same file.
- The first stream is not destructed at the exact same point it was in
the previous code (but rather when the second stream replaces it on
assignment to the same variable). An arbitrary scope could have been
introduced to destruct the object at the same place, but it doesn't
seem to be necessary and would make the code a bit strange.
