Exceptions thrown when getting/setting MAXIMUM_TABLE_DIRECTORY_SIZE_IN_GB configuration setting

[mapipolo]

I'm implementing the tabular interpolation features of CoolProp and quickly blew past the 1.5 GB table directory size limit, so I'm trying to raise the limit. However, either of the following lines of code throws an ApplicationException with message "invalid item":

double dirSize = CoolProp.get_config_double(configuration_keys.MAXIMUM_TABLE_DIRECTORY_SIZE_IN_GB);
CoolProp.set_config_double(configuration_keys.MAXIMUM_TABLE_DIRECTORY_SIZE_IN_GB, 2.0);

As a point of reference, running either of the following two lines works as expected:

string path = CoolProp.get_config_string(configuration_keys.ALTERNATIVE_REFPROP_PATH);
CoolProp.set_config_string(configuration_keys.ALTERNATIVE_REFPROP_PATH, @"C:\REFPROP\");

interesting, I'll investigate. Nice issue report. C#, right? Shouldn't matter, but ....

C#, correct. Nightly build of CoolProp with REFPROP 9.12.

Smells like a bug. I'll see.

By the way, Ian, is it possible to change the directory where CoolProp stores the tabular data it generates? I assume it must be, but haven't encountered any way to do so.

Nope, it is hard coded in the TabularDataLibrary::path_to_tables function, which internally calls
the get_home_dir function, see http://www.coolprop.dreamhosters.com/binaries/sphinx/_static/doxygen/html/class_cool_prop_1_1_tabular_data_library.html#aedd1aff69c7bd0510f7f2be3c52fa468

Wild stab - do you have an older copy of the platform independent files?

In my configuration_keys.cs file, I see:

public enum configuration_keys {
  NORMALIZE_GAS_CONSTANTS,
  CRITICAL_WITHIN_1UK,
  CRITICAL_SPLINES_ENABLED,
  SAVE_RAW_TABLES,
  ALTERNATIVE_REFPROP_PATH,
  ALTERNATIVE_REFPROP_HMX_BNC_PATH,
  REFPROP_DONT_ESTIMATE_INTERACTION_PARAMETERS,
  MAXIMUM_TABLE_DIRECTORY_SIZE_IN_GB,
  DONT_CHECK_PROPERTY_LIMITS
}

which line exactly is causing the exception?

With regards to the path, it is hardcoded as @jowr says, but we could add a configuration variable. Can you file a separate issue please and I'll implement it?

My platform independent files are a few days behind my copy of CoolProp.dll, but yes, my configuration_keys.cs file matches that.

I don't know if you made any related changes in the most recent nightly build of CoolProp.dll, but I downloaded Tuesday's build yesterday, and the problem has disappeared.

[ibell]

So we can close this issue? If so, go-ahead and do that. Maybe somehow
you got 5.1.1 instead
