output waring for cygwin process running at setup__.exe

output waring for cygwin process running at setup__.exe

[Tatsuro MATSUOKA]

On cygwin setup, one has to kill cygwin process to execute autorebase in the end of setup process.
I think it is better to output worning at start stage setup if cygwin process running.

I'm not quite sure of the steps you took to come to such conclusion.
Can you please explain?

Sorry for my inadequate description.
At postinstall stage, cygwin setup execute /etc/postinstall/0p_000_autorebase.dash,
this sometimes fails when Cygwin process(es) is(are) alive.
Acooding to http://cygwin.wikia.com/wiki/Rebaseall,
we have to kill or stop cygwin porcesses and sevices before rebase.
This is why I propose that warning messages in pre-install stage in cygwin setup.

Sounds about right.
If there's an existing Cygwin install, it is possible to run ps.exe and see if
it find any running Cygwin processes before attempting an update.

If there's not an existing Cygwin install, you don't really have to worry too
much about Cygwin processes running. ;^>

The docs all recommend killing all Cygwin processes *before* running setup, as
setup can not replace running exes and active dlls during the installation
phase, before postinstall rebase of replaced dlls.

If setup can not replace any exe or dll, it warns you have to restart your
system to complete the replacement. After the restart, you then have to rerun
setup with no Cygwin processes running to successfully rebase replaced dlls.

The problem is, not all packages are prepared to deal with locked shared
objects (in truth, none are).
Which may leave system in an inconsistent state even after reboot.

Sever survice like cygsever always start after windows re-start if it is registered.
So restart does not always kill cygwin processes.
I do not want to force to  kill cygwin process by setupXX.exe but output the warning.

Cygwin setup uses standard Windows wininit processing to perform the
replacements on restart.

Only if a service is registered for Automatic startup: you can change this to
Manual, and restart services in a permanent last postinstall script prefix e.g.
zp_zzz_services.dash, which can also be executed by a scheduled task, before
starting Cygwin from e.g. a XWin Server taskbar or Start Menu shortcut.

Cygwin setup could operate more consistently and transparently if setup warned,
then shutdown running Cygwin services and noted them, and killed all remaining
processes, before beginning the install phase, then restarted previously noted
running services after the postinstall phase.

Hi,

I use script [1] for years in order to:
- allways use latest setup.exe
- stop all running Cygwin services* before setup is started
- start formerlly runnig Cygwin services after setup is done
- and more

*) services I usually run; feel free to add more services according your 
needs

Does it schedule a rebase after replacement?

Or it could rename the objects it failed to delete, and use wininit to
cleanup.

In reality is better to NOT have cygwin process running before
running setup otherwise the update will fail if the
running programs od depending shared libraries are to be update
