Mojo format error upon labels with newline #12312

Open exalate-issue-sync[bot] opened 1 year ago

exalate-issue-sync[bot] commented 1 year ago

When mojo is writing columns label in https://github.com/h2oai/h2o-3/blob/c46a83511d9b90ab2e078526e9c2284de9516ee8/h2o-core/src/main/java/hex/ModelMojoWriter.java#L246 Some label has newline in it

So when reading mojo back from model.ini in https://github.com/h2oai/h2o-3/blob/307794e5112fbd1deeb309cb4f0eaea88be8a33c/h2o-genmodel/src/main/java/hex/genmodel/ModelMojoReader.java#L180

More labels will be read than specified in n_columns, causing https://github.com/h2oai/h2o-3/blob/307794e5112fbd1deeb309cb4f0eaea88be8a33c/h2o-genmodel/src/main/java/hex/genmodel/ModelMojoReader.java#L179 To throw the Error {code} n_columns variable is too small. {code}
