Did the inability of UoW to read a Cygwin created file ever get explained?
Last I saw was from Evgeny Grin, which contained the iacls dumps.
What jumps out is that the non-Cyg files have X perms, the Cyg file does not.
I assume others noticed that. Of course, X perms should not be needed to read
Also, the perms shown by the UoW ls differ a lot from what the Cyg ls shows,
for the same file. It would seem they are _interpreting_ Win perms as
different sets of Unix perms.
And the creat() operation may be _assigning_ the Win perms differently, too.
Maybe differences handling umask values, or maybe different "effective" umask
values, somehow? Yet somehow I doubt the umask is it; there could be lots of
I am not a bit surprised things differ. Who do we think is right, if either?
And then, an interesting question. Suppose we Cygwin users think we have
identified a defect in UoW. Do we notify the MS people? Whom and how? I
guess I think we should, though I'm not happy about it. (If they are wise,
they will be lurking here, for exactly this reason...)
Really, I am just curious, no dog in any fight...
