Hi,
I'm trying to investigate failure of JImageExtractTest on Windows.
Failing method is testExtractToReadOnlyDir, issue is simple. It is trying to
extract jimage to read-only directory and it must fail. AFAIK it is not
possible to create read-only directory. I tried set rights programaticaly from
java, manually from windows explorer and windows cmd. Without any success. It
effectively just deny access from explorer and cmd.
Is there any Windows expert who can confirm this or suggest solution? Only
solution I've found is to write something to some mounted ISO image, which is
not an option here.
In case this will be confirmed I suggest to skip this single test on Windows.
I don't have time to detail this just now but you can specify a DACL (as a
FileAttribute<List<AclEntry>>) to Files.createDirectory so that the directory is
created with an initial DACL that denies access. Alternatively, you can change
the DACL of an existing directory. Yes, a bit complicated to setup. I don't
think it would be too much of a surprise for this sub-test to only execute on
platforms that support POSIX file permissions (I think some of the tests check
this already).
Yes, I've tried this, but I'm still able to create a file in that directory. It
prevents just from accessing the directory from explorer or cmd. However, I can
freely access it from cygwin or java.
