Correct? (Cygwin 2.0)

Correct? (Cygwin 2.0)

[Houder]

Hi Corinna,

Reference: https://cygwin.com/ml/cygwin/2015-04/msg00201.html
 - [ANNOUNCEMENT] TEST RELEASE: Cygwin 2.0.0-1

Sorry, Corinna, but I have to ask: will this be the correct behaviour of Cygwin
from now on? ... because I am very much surprised ...

Is there anything I can do (settings directory?) ... to "improve" on what I am
experiencing now?

I create a file (called aap), do not modify its properties (chmod), and then it
turns out that the properties have changed ... Surprise!

Regards,

Henri

 - reinstalled Cygwin, selected Cygwin 2.0
 - using an UNelevated bash shell
 - touch aap
 - chmod -x aap # afterwards the write-bit turns out to be set for group None!
 - chmod -w aap # does not help! (no modification)

I really appreciate bug reports, but, please, try to keep the threading
intact.  Please reply to mails rather than creating new threads which
have no connection to the original threads.  Or if so, at least set the
"In-Reply-To:" Header field correctly.

By additionally changing the subject you're making searching the
archives unnecessarily hard for others.  I changed the subject back.

It's what we haxxers call "a bug".  I made a typo in another function,
copy-pasted the code over to the chmod function, fixed it in the
original function and then forgot to fix it in chmod.

Btw., the output from SetACL isn't that helpful, because it doesn't
add information to what icacls already delivers.  What I'd be more
interested in is the output of our own getfacl in conjunction with
icacls.  It allows me to see the POSIX ACL the internal ACL reading
routine created from the Windows ACL.

I just uploaded a new test release 2.0.0-0.2.  It's supposed to fix
this bug.  Give it a bit of time to hit the mirrors.


Thanks,
Corinna

:-) ... I understand ... my problem is, that I am usually NOT subscribed
to the (any) list, and that I process all my e-mail using webmail, and as
far as I aware of, it does not provide the "In-Reply-To" feature.

As a result of that, my "first" e-mail will be "out-of-line". Sigh.

:-) Will do!

You can post via Gmane rather than the webmailer.

... wait ... more waiting ...

Confirmed. This bug has gone. (you knew where to look for it, did you
not? :-)

Many thanks for all your hard work!
