I applied a patch and uploaded new test versions, 2.863, to

  https://cygwin.com/setup-test-x86.exe
  https://cygwin.com/setup-test-x86_64.exe

These should fix the aforementioned bug I introduced, as well as another
subtil problem when checking and unchecking the Bin/Src boxes.  If both
boxes were deselected, the package got uninstalled without showing up in
the "Pending" view.  I worked around that by setting the package state
explicitely to "Uninstall" if both boxes got deselected.

This version also introduces an experimental option -m/--mirror-mode.

There's something bugging me for a long time as well.  We're running our
own Cygwin mirror on a local Linux box.  The directory is mounted via
NFS on my Windows boxes.  So, rather than installing from internet, I
"Install from Local Directory", with the local directory being the
NFS-mounted mirror directory.

This works fine, except that, after parsing setup.ini, setup hangs
unresponsive for about 2 minutes.  Only then the chooser window opens.

It turned out that the 2 minutes are spent iterating throught the full
set of packages and testing each package and each packageversion if the
underlying package file exists in the download directory.

Given that the directory is a mirror in my case, the test makes only
marginal sense.  Therefore I added the -m option which avoids most file
system access and only checks in a border case (installed version is not
in setup.ini).

If you're doing as I do, running a local mirror, you may welcome this
option.  I just don't guarantee that it always works ;}  If you find a
bug, don't hesitate to report it.


Thanks,
Corinna
