* Patch Mathematica
Mathematica installer moves all files and directories from installation directory to a backup one. The problem is that it also moves .spack to this backup location. Once it's done it does not move .spack back where it was.
My patch creates a copy of .spack to /tmp then moves it back right before exiting the install call.
* Make lint happy
* Use Spack native copy()
As suggested in peer-review let's:
- Copy .spack to stage directory so I don't have to use random
- Use Spack native copy() to do these operations
* Use join_path to create paths
As per peer-review suggestion:
- Use join_path to create paths
- Use copy_tree since we're copying a directory that could have sub-directories
Fixes#11781
* Rename build log to spack-build-log.txt
* Rename environment variables file to spack-build-env.txt
* The name of the log and env files is now the same during the build
and after the build completes
* Update packages which referred to the build log/env files
* For packages installed before this commit using older names for the
build and env files, search for the older names
