Hi everyone,
the following is about my current work to manually determine package
dependencies for the 11 agents, which are part of Colorado-I.
I already got some positive feedback by Detlef Ulherr for
SUNWscPostgreSQL, SUNWsctomcat and SUNWscmys, and from Neil Garhtwaite
for SUNWscdhc and SUNWscsmb - thanks a lot!
I specifically seek review for
SUNWscapc (HA Apache)
SUNWscdns (HA DNS)
SUNWsckrb5 (HA Kerberos)
SUNWscnfs (HA NFS)
SUNWscs1as (HA SunOne Appserver / Glassfish)
since I am not the agent expert for them, I would appreciate if
the owners could have a look to verify and sanity check with the
dependencies I found and determined.
Here is what I did:
Step 1) Going through all source files of the individual agents, I did
record the commands getting invoked by the code, the
corresponding packages for those commands, and which agent did
really use them, marked with a "*" in the correspinding row.
I did also record which files I did analyze.
The result is in a StarCalc sheet, available at
http://opensolaris.org/os/project/colorado/files/Colorado-I-IPS-agent-dependencies-20090210.ods
Step 2) The StarCalc sheet can get saved as .csv file, where the
separator is "," and content of fields is kept in double quotes.
The result is available at
http://opensolaris.org/os/project/colorado/files/Colorado-I-IPS-agent-dependencies-20090210.cvs.txt
Step 3) Have a script which uses awk to extract the package list by
looking at the "*" recorded for each package.
This then results into a sorted list of uniq packages.
The script I used is available at
http://opensolaris.org/os/project/colorado/files/map-agent-package-dependency.ksh.txt
Step 4) Verify the list shown by the script of Step 3) and insert the
missing entries into the usr/src/ipsdefs/<package>/depend_static
file. I did leave out entries already recorded within depend_auto.
The result can be reviewd within the following webrev:
http://cr.opensolaris.org/~frueauf/colorado-1-ips-agent-dependencies/
Please note the following:
- I did bump the year to 2009 within the common copyright file. Guess the
same needs to be done within the core gate (was only recently done within
the pkgdefs area, but not within ipsdefs). Is it ok to have it part
of this
review/putback? I am also happy to leave it out, if required.
- I did add the dependency to the group package ha-cluster-framework-minimal
to all packages. That way if the user just installs the agent package,
it should pull in all required packages in order to configure a working
cluster.
- The following files contain questions, where I seek input, before I
finalize and send out the webrev to ha-clusters-discuss:
* SUNWscapc/depend_static
* SUNWscdns/depend_static
* SUNWsckrb5/depend_static
* SUNWscnfs/depend_static
* SUNWscs1as/depend_static
a) for some I am not sure to record the OpenSolaris package
dependency for the application - specifically I don't know if it
is a good idea to depend on just one version.
I would be fine with nfs and krb5, but I doubt if we want that for
dns and apache - although we have hardcoded paths. At least in the
case of apache we offer choice, and maybe users do not want both
versions.
b) for the non-GDS based agents my auto conversion recorded the
dependencies
from the pkgdefs common depend file. I would tend to delete those
entries,
but would like to get feedback how reasonable they are.
