Yum plguin help

[Jalandhar Singh]

Hi,

I have written a plugin for yum to remove the specific rpm during downgrade. But I want to remove the rpm before yum will update the other rpms. (want to restrict the order using yum plugins, instead of doing in the spec file)

Can we restrict the order of the update/install/remove/clear/erase during the yum downgrade/upgrade/install procedure in the yum plugins ??

Content of yum plugin:

def postresolve_hook(conduit):
        tsInfo = conduit.getTsInfo()
        rpmdb = conduit.getRpmDB()
        oldlen = 0
        while oldlen != len(tsInfo):
                oldlen = len(tsInfo)
                opts , commands = conduit.getCmdLine()
                conduit.info(2, commands[0])
                # If the command line input is 'update'/'upgrade'/'install' and 'sde rpm state is UPDATE' then remove these five rpms.
                if ( commands[0] == 'downgrade' ) and ( commands[1] == 'sde' ):
                                for txmbr in tsInfo.getMembersWithState(output_states=[TS_INSTALL]):
                                                if txmbr.name == 'sde' and txmbr.version < '7.30':
                                                                conduit._base.remove(name='tclkit', arch='x86_64')
                                                                conduit._base.downgrade(name='svpermissions', arch='x86_64')
conduit._base.downgrade(name='svsde', arch='x86_64')


Note: I want to restrict the order of the highlighted part. Frist remove then downgrade other rpms. But yum internally do update/install first as compare to erase/remove.

Thanks
