dbconfig-common upgrade strategy

[PICCA Frederic-Emmanuel <frederic-emmanuel.picca@synchrotron-soleil.fr>]

Hello,

I need to backport the tango-db package which use dbconfig-common infrastructure.
this allow to upgrade the tango-db mysql tables during the upgrade process

the process use files named with the version of the transition.
If the database need to be upgrade with the package
8.1.2+dfsg-1 this is the name of the first package which provide the transition.
now the version is 8.1.2c+dfsg-3

for now I have these files in my package

picca@mordor:~/Debian/main/tango/tango/debian/mysql$ ls
7.2.0~rc1+dfsg-1  7.2.6+dfsg-1  8.0.5+dfsg-1  8.1.2+dfsg-1


So if someone upgrade tango-db stable -> sid

7.2.6+dfsg-14 -> 8.1.2c+dfsg-3

the process apply 8.0.5+dfsg-1 and 8.1.2+dfsg-1 upgrade

now with the backport of 8.1.2c+dfsg-3~bpo70+1

I need to apply also 8.0.5+dfsg and the same transformation done for 8.1.2+dfsg-1

but

$ dpkg --compare-versions 8.1.2+dfsg-1 gt 8.1.2c+dfsg-3~bpo70+1; echo $?
0

this mean that I need to rename the file 8.1.2+dfsg-1 with another name for the backport.

my question is should I use the 8.1.2c+dfsg-3~ as new filename instead of 8.1.2+dfsg-1

to deal with the backport.


If some one has some experimence with dbconfig-common and backports


I hope I was clear enought.

thanks for your help


thanks


Frederic
