As the generated Cargo.toml is shipped as part of a release
tarball, build from the source directory but set the cargo
CARGO_TARGET_DIR to the build directory.
Don't treat 'external' parsers as more experimental. All parsers
depend on crates to some extend, and all have C glue code. So the
distinction doesn't really make sense.
The 'debug' feature is enabled if suricata was configured with the
--enabled-debug' flag.
If enabled, the SCLogDebug format and calls the logging function as
usual. Otherwise, this macro is a no-op (similarly to the C code).
Add option to put Rust code in non-'--release' mode, preserving
debug symbols.
Until now Suricata would have to be compiled with --enable-debug for
this.
During configure, substitute the path of cargo, as well as the
value of CARGO_HOME as variables. This fixes the case where a
user might do:
make
sudo make install
Which will cause the cargo bits to be rebuilt, including
re-downloading external crates.
By saving these to variables we can be sure that the same
values are used during make install as were used during
make which prevents the Rust artifacts from being rebuild
during "sudo make install".
Allow distcheck to pass if cargo vendor is not found by not
failing out. It is not required to successfully build a dist
tarball, the Rust sources will just not be vendored in.
Also don't fail out make dist if Python is not installed. A build
will still be successful is Python is available on the end
build system.
Update nom to ~3.0.
Prefix dependencies with ~, which will allow for newer patch
versions only. Minor version updates should get a test before
using.
Remove Cargo.lock from the repo, but still generate as part
of the vendoring process for release builds. This will ensure
that all users of a particular distribution tarball will be
linking against the same Rust dependencies.
Rust is currently optional, use the --enable-rust configure
argument to enable Rust.
By default Rust will be built in release mode. If debug is enabled
then it will be built in debug mode.
On make dist, "cargo vendor" will be run to make a local copy
of Rust dependencies for the distribution archive file.
Add autoconf checks to test for the vendored source, and if it
exists setup the build to use the vendored code instead of
fetching it from the network.
Also, as Cargo requires semantic versioning, the Suricata version
had to change from 4.0dev to 4.0.0-dev.
