RE: setup.exe: Woe is me!

[Phil Bewig]

I just killed setup.exe after over an hour of inactivity.  A total
of over 125MB of disk space has disappeared in the last few
hours while I have been running setup.exe, reading and
replying to email on the cygwin mailing list in this thread
using MS Outlook, and searching the cygwin mailing list
archives with MSIE.  When I killed setup.exe (using the
"cancel" button on the progress screen), I received a popup
message "Cannot open log file d:\/var/log/setup.log for
writing."  Are there any additional clues here?  What is
consuming disk?  And how do I get it back?

Thanks again,

Phil

My firewall has gotten in the way many times with cygwin setup.  Try 
disabling your firewall just during setup.  Also, maybe try using a 
different mirror, you may be experiencing long network delays.  My cygwin 
install dir currently contains 145 mb of downloaded data.

Phil,

Setup.exe first downloads the tarballs of the Cygwin packages from your
chosen mirror to your local disk, into a subdirectory of the "Local
Installation Directory".  If you're on a dial-up connection, it may take
quite a while, depending on the number of packages you chose to install.
Once all the packages are downloaded, setup.exe switches to the
installation phase, where it installs the files contained in those
packages (by unpacking them).  The third phase runs whatever postinstall
scripts were in those packages.

My guess is that the space has been taken up by the local cache directory.
Setup.exe runs in multiple threads.  The files are downloaded in a
separate thread from the main thread (that handles Windows messages and
updates the main window).  If the main thread is hung, downloads will
still continue, giving the impression of disappearing disk space.  The
fact that the "Cancel" button works means that the main thread is not
truly hung, but something is probably screwed up with the sequencing logic
somewhere...  It would be really nice to get a gdb backtrace, since it's
so reproducible for you.
	Igor
P.S.  FYI, larger packages (e.g., tetex) easily run into tens of megabytes

OK, I'm taking a wild guess here, but just in case setup doesn't like the
'\/' in the install path, try setting your cygwin root to "d:\cygwin".


Also, where is the discspace disappearing? C: or D:? If D:, then if all you
have on that drive is Cygwin stuff, it should be easy to track down where
the space is going to?



Max.

my WAG:
setup is looping: trying to create a file, failing, and trying again.

Here's what I'd like you to do:
Check your registry for cygwin mount points, both per user and per
machine. There may be a decompressed cygcheck you can download to do
this. If there isn't, then have a look on this list for other references
to the mount point data. (It's not supported to make registry changes
manually, which is why I'm *not* putting the keys in this email).

If, as I suspect, you have some broken mount points, just delete the
entire cygwin keys in both user and machine subtrees.

Now, run setup again, and when you are installing, be very very sure to
install to somewhere like "D:\cygwin", not to "D:\".

If that doesn't work, then I'll brew up a log-on-the-spot version of
setup.exe for you, which will let us see whats going on.

Cheers,
Rob

Rob,

I don't know how much extra effort it'll be, but wouldn't a
"log-on-the-spot" command-line option make sense anyway?  Or is that what
you meant?

Attatched is a patch implementing log-on-the-spot.

BEWARE: This patch is very old, and not resynced with HEAD.
Nevertheless, it might save someone 2 minutes or so reimplementing this.

Actually, I just meant building setup with the extant patch to change
the logging behaviour.

A command line option we can include for releases would be neat. The
patch Max has just reposted would be a good basis for that..
