Unpacking mwk files in 0.5

Support
1

Hi Chris,

I got the error below when unpacking an mwk file using the getCodecs provided with MWorks 0.5. This was an mwk file collected in MWorks 0.5.

However, I was able to unpack using getCodecs.mexmaci64 provided in MWorks 0.4.5.

What known issues are there with the MWorks 0.5 unpack code? Also, are there new features in this code not available with the version from 0.4.5?

Thanks,

Elias

codec = getCodecs(mwk_filename);

Hi Elias,

I got the error below when unpacking an mwk file using the getCodecs provided with MWorks 0.5.

This looks like the same issue that affects that MATLAB client plugin. Apparently, it isn’t limited to the plugin or MATLAB R2013a. Crud.

I think I’ve figured out how to fix this problem. Unfortunately, it’s going to require changes to how MWorks links to its supporting libraries, so I can’t just send you a new MEX file. For now, using the 0.4.5 MATLAB data tools is probably the only workaround.

Also, are there new features in this code not available with the version from 0.4.5?

From the 0.5 release notes:

  • MATLAB data tools have been almost completely rewritten. Improvements include better and more robust data conversion, reduced memory usage, and more helpful parameter validation and error reporting.
  • If an MWorks dictionary cannot be converted into a valid MATLAB structure array, it will be converted into a containers.Map object if possible, a fallback structure array otherwise
  • MWorks strings with embedded NUL characters are now converted into MATLAB uint8 arrays
  • getEvents will now optionally return event codes, times, and values in three separate arrays

In general, they just work better than they did before (except for when they crash MATLAB, that is). However, it should be completely safe to trash the contents of /Library/Application Support/MWorks/Scripting/Matlab and replace it with the files from a 0.4.5 install. (The 0.4.5 MATLAB tools don’t depend on the MWorksCore framework, so there’s no risk of binary incompatibility.)

Chris

After investigating this issue further, Elias determined that the crash was happening with a pre-release nightly build of 0.5, but not with the release build. Thus, it appears that the previously mentioned issue is in fact limited to the client plugin and MATLAB R2013a, which jibes with the results of my testing.
