Description Pekka Savola 2000-08-18 09:10:16 EDT
If a package specified in 'comps' file is missing, the installer
bombs.  This also happens if a file listen in 'hdlist' is missing.

I think there was an option in RH 5.x installer to
Skip/Skip All/Retry/Abort when this happens.  

This would make anaconda a lot more resistant to stupid 
problems especially when customizing or updating your 
RPMS tree.

Added to feature request list.
Comment 2 Pekka Savola 2000-08-22 03:02:57 EDT
For the record, rudimentary functionality  was in RHL 6.0

Comment 6 Brent Fox 2000-11-20 11:25:42 EST
Implemented in internal builds.  Brock, please test.
Comment 7 Brock Organ 2000-12-11 17:28:08 EST
verified fix ...

a "missing package" dialog does occur that allows the user to know they have bad
or incomplete media ... (if for example a rpm package is missing) ... no
traceback happens ...
Comment 8 Pekka Savola 2000-12-11 17:47:21 EST
Does this only notify the user, thus avoiding a traceback?

This is good, but still a suboptimal solution.  For network installs (ie: media where the 
contents may change or become unavailable due to connection problems etc.) there really
should be a retry and/or skip option.  That way the ridiculously long (dozens of minutes, 
if not hours?) network timeout could be reduced too.
Comment 9 Erik Troan 2001-01-09 15:18:22 EST
The missing dialog is as far as we're going to go on this one. Packages missing
frmo the comps file means something is wrong, and it needs to be fixed rather
then just ignored by the install.
Comment 10 Pekka Savola 2001-01-09 15:30:53 EST
This is true.  But also consider:

You have package 'aaaa' missing.  The dialog appears, you fix it.  Reboot, try again.  Then you notice
you have package 'bbbb' missing.  The dialog appears, you fix it.  Ad infinitum.

This is how it has to be done now.  Dialog is a good way to report the error more gracefully.

*But* if at all possible, make it so that all packages are scanned for possible problems so that you can 
fix everything in one sitting.  

_That_ is what 'Skip' option was very good for.  

Actually skipping something because it was missing would definitely be a braindead 
idea, especially if it's a vital component.
Comment 11 Erik Troan 2001-01-09 15:41:47 EST
How about contributing a script to check for this on another system?
Comment 12 Pekka Savola 2001-01-09 15:57:37 EST
Hmm.  I guess it should do something like

 - check that all RPMs in comps exist in the tree 
  * I can't think of anything but something ugly like
if "`rpm -qp xxxnameincomps*.rpm --queryformat "%{name}`" = xxxnameincomps


 * as a side effect, this would mostly check the integrity of those files (I've one-byte corruptions sometimes)

- Check that all files mentioned in hdlist are there and rpm --checksig them for errors and package corruptions

- I guess it's allowed to have multiple versions of the same package (newest always picked) in the same dir.

Any other cases to check?
Comment 13 Erik Troan 2001-01-09 16:04:35 EST
That looks right. The easiest way to do this is to use python, which will let
you use the comps.py in anaconda-runtime to get the list of packages in the
comps file, and use the rpm python module to read the hdlist. I'm not picky
