driver_drake() fail on Windows due to file name length on gcam-v7.0 #1242

Open robbieorvis opened 1 year ago

robbieorvis commented 1 year ago

I attempted to run driver_drake() on the the latest data system for v7 but it failed due to the temporary data file names being too long. There is a comment in the driver.R file that says to re-run devtools::load_all() when running into this issue, but it does not fix the problem. This means that driver_drake() cannot currently be used on Windows with the gcam-v7.0.

Here's the error:

Error in file.rename(tmp, filename) : expanded 'to' name too long

Also noting that even running driver() for the data set (using the distributed GCAM data system files in the v7 folder, produces the following error for "module_gcamusa_L270.limits":

Error in check_chunk_outputs(chunk, chunk_data, input_names, promised_outputs = po, : Some precursors for 'L270.NegEmissBudget_USA' aren't inputs - chunk module_gcamusa_L270.limits

Sorry about that bug in module_gcamusa_L270.limits--I've posted a fix to my cloned repo that you can merge in, at https://github.com/pkyle/gcam-core/tree/gpk/bugfix/gcam7_limitsfix From a command prompt, you'll need to add that repo (and name it; I'm just calling it github_pkyle in the steps below), fetch from that repo, and then merge in the branch (which is just two very small commits): git remote add github_pkyle https://github.com/pkyle/gcam-core.git git fetch github_pkyle git merge gpk/bugfix/gcam7_limitsfix

Thanks for this @pkyle.

On a related note - any plans to address the issue with file length in driver_drake() on Windows? Pretty limiting to not have that available, unfortunately.
