Unattended install "remembers" the download option

Unattended install "remembers" the download option

[Drake, Richard R]

Hello,

Does anyone know how the cygwin setup "remembers" install settings?  Such
as --download.

I ran the setup once using --download, and now every time I use it, it
runs with that option by default.  The problem is that I want to use
unattended mode to install additional products but they don't get
installed because it assumes the download only option.

Is there a "download and install" option that can be used?  In order to
override the "download only" option.  I didn't see one.

What is really curious is where this option is being stored.  If I knew
that, then maybe I could remove that setting so it would revert to the
default setting.

Thanks,

-rich

Look in /etc/setup/setup.rc. I bet the line following "last-action" is
just "Download"
in your file. Mine is "Download,Install" (after a tab).

The first setup screen after the splash/version screen has these options,
choose: Install from internet (implies Download first).

Thanks Wayne, that was the clue I needed.

Turns out cygwin will use the Windows Registry to store previous install
locations, and in that previous location I had the "download only" option
set.  The setup program used the Registry to find a previous install
location (/etc/setup/setup.rc file) and used that to populate some options.

To easily check the registry for all your installations, try:

	$ ls -R /proc/reg*/HKEY*/SOFTWARE/Cygwin

to see the useful content:

	$ find /proc/reg*/HKEY*/SOFTWARE/Cygwin -type f | xargs head; echo

to get the settings from /etc/setup/setup.rc for: last-cache, last-mirror,
last-action, net-method (Direct or proxy):

	$ sed "0,/^$SETTING/d;s/^\s\+//;q" /etc/setup/setup.rc

to change it, at your own risk, type carefully:

	$ sed -i "/$SETTING/{n;s/^\s\+.*/\t$NEW/}" /etc/setup/setup.rc

I picked this up while forking apt-cyg at:
	https://github.com/BrianInglis/apt-cyg
with three pull requests against the original at:
	https://github.com/transcode-open/apt-cyg
to:
* fix postinstall processing so it works the same as current setup,
   does not rename permanent and dash scripts, and runs only once
   after all packages have been installed (even recursively);
* add apt-get-like source command with options for --download-only
   and --compile, which uses whichever is available in the package:
   -cygport script, so it can auto-pre-install build dependencies to build;
   - configure script;
   - Makefile;
   both of the latter require build dependencies manually preinstalled;
* quieten wget by adding the -nv --non-verbose option.
Download latest branch wget-non-verbose and try it if you use apt or want to
easily download and/or build sources, especially those using cygport (many):
master branch reflects the original whose author seems unresponsive lately,
so pull requests may never be merged.

You probably want to split the white-space changes into a separate
commit.

The postinstalll script logic is still wrong, but I don't think it's
fixable completely since it'd try to run the postinstall scripts from
the same Cygwin instance as the one it had installed to.

For a description of how it is supposed to work and implemented in setup
see: https://cygwin.com/ml/cygwin-apps/2014-12/msg00148.html

Achim.
