Mac VM: SecurityManager default untrustedUserDirectory

Depending on the VM version evaluating

SecurityManager default untrustedUserDirectory

gives inconsistent results:

4.2.5beta1U: '/Users/renggli/Library/Preferences/Squeak/Internet/My
Squeak' (ok)
5.8b10: '/foobar/tooBar/forSqueak/bogus/' (strange)

Looks like there is something missing in for 5.8b10?

This makes certain tests of the Filesystem library fail.

4.2.5x SqueakUnTrustedDirectory -> ~/Library/Preferences/Squeak/Internet/My Squeak/

5.8.x SqueakUnTrustedDirectory -> /foobar/tooBar/forSqueak/bogus/

What would you like it to be?

'/foobar/tooBar/forSqueak/bogus/' doesn't look meaningful, it doesn't
even exist on my system.

The Filesystem library uses #untrustedUserDirectory this to find the
home directory. Maybe there is a better way to do that on Mac?

Re: Mac VM: SecurityManager default untrustedUserDirectory

Asking for the home directory should invoke a platform specific method that does the right thing.
Perhaps on unix based machines you can use ~ ? However on systems that have file security turned on then you
might need to lookup the squeak un trusted directory since the answer could be different.

Surely you use getenv("HOME") right? ~ is an abbreviation implemented in the shell. It is not meaningful to system calls; i.e. open("~",0) attempts to open a file called "~" in the current directory, /not/ /Users/me.

However on systems that have file security turned on then you
might need to lookup the squeak un trusted directory since the answer could be different.

Re: Mac VM: SecurityManager default untrustedUserDirectory

In reply to this post by johnmci

IMHO good defaults would be

SqueakUnTrustedDirectory
~/Documents/Squeak/

SqueakTrustedDirectory
~/Library/Application Support/Squeak/

(these are settings in Info.plist in case you were not aware)

IMHO for getting the home directory there should be a new FilePlugin primitive. You could use FFI or possibly OSProcess in the mean time.
