working on using ChunkIdentifier to compare chunks uniquely instead of using chunk number (which could change if a non-code chunk is added before the code chunk)

rc2compute

This is the R backend portion of the rc2 project. It builds rserver which listens for connection requests and then forks a copy of rsession. Each rsession process wraps an R session via RInside.

All communication is via json. Files are managed via the PostgreSQL database.

antlr

to compile the runtime

• cd vendor/antlr
• rm -rf build/* run/* antlr-src/*
• unzip -d ./antlr-src/ antlr4-cpp-runtime-4.8-source.zip
• cd build
• cmake ../antlr4-src
• DESTDIR=../run make install
• cd ..; mv run/usr/local/* to .; rm lib/libantlr4-runtime.so*

to generate the souce

java -Xmx500M -cp vendor/antlr/antlr-4.8-complete.jar org.antlr.v4.Tool -Dlanguage=Cpp -Xexact-output-dir -o parser/generated/ -visitor Rc2Parser/Rc2Lexer.g4 Rc2Parser/Rc2RawParser.g4 Rc2Parser/R.g4 parser/RFilter.g4

building package with docker runtime

1. Build the rc2/dev image using the dockerfile. Then select that as the runtime in the Run menu.
2. Build/Debug/test per normal.
3. Run the following to create the tarball in the build directory: docker run --rm -w /build/compute --volume /home/mlilback/rc2/compute:/src/compute --volume /home/mlilback/rc2/compute-build:/build/compute rc2/dev:latest /usr/bin/make package

building notes

On checkout of project, use git clone --recursive <URL> <Local Directory> to checkout submodules, too.

1. make a build directory, cd into it, run cmake .. then make

In vendor/json-schema-validator need to run git fetch && git fetch -tags and then git checkout 2.0.0.

In vendor/g3log run git fetch && git fetch -tags and then git checkout 1.3.2.

When RInside is installed on a development machine, need to go to /usr/local/lib/R/library/RInside/libs and ln -s /usr/local/lib/R/site-library/RInside/libs/RInside.so libRInside.so pushd /usr/local/lib/R/site-library/RInside/libs; sudo ln -s RInside.so libRInside.so

the dist is made via call to make package.

tips

• use addr2line to turn an address from a deployed stack trace to a source line on the dev machine.

• to build RInside use R CMD INSTALL RInside -l /usr/local/lib/R/site-library
