I will try and explain it Again
capability == depstring as in "yum install depstring1 depstring2".
Given a set of depstring's i need to know the package that provides
each depstring and the other packages this package is dependent on.
the way i am doing it till now was using 'pexpect' and run the command
"yum install depstring1 depstring2 depstring3 ..." and the capture stdout
and parse the output and generate the rpms list.Why i am doing this
because the build team needs the list for some reason.
Now need to do it using the yum api.
So i will write the psuedocode again :
deplist = [ depstring1 , depstring2 , ...]
for depstring in deplist:
packages.append ( yum.YumBase.returnPackageByDep ( depstring ) )
for po in packages :
yum.tsInfo.addInstall (po)
yum.buildTransaction()
mems = yum.tsInfo.getMembers()
for mem in mems:
pkgtuple = mem.po.returnPackageTuple()
#From 'pkgtuple' generate filename
#save filename.
Thank you s.v for the reply .
