Introduction

5. Version comparison algorithm
for Deb packages
What's in it for you?

6. 6
Are you familiar with this?
We are seeing a version compare failure in Uyuni with two Ubuntu packages:
libtre5-0.8.0-3+deb7u1ubuntu1
libtre5-0.8.0-3ubuntu1
Uyuni says the second is newer, but apt says the first one is
newer:
# zypper vcmp "0.8.0-3+deb7u1ubuntu1" "0.8.0-3ubuntu1"
0.8.0-3+deb7u1ubuntu1 is older than 0.8.0-3ubuntu1
# if $(dpkg --compare-versions "0.8.0-3+deb7u1ubuntu1" "gt" "0.8.0-3ubuntu1"); then echo true; fi
true

7. 7
• In the past we tried to write 1 algorithm for both types but they are so incompatible
that it was not working as intended (one notable example is in the previous slide)
• When we compare a evr_t we need to know what algorithm to use
• evr_t was enhanced by type
• Depending on the type we choose the correct implementation
• Comparing incompatible types will fail

8. 8
The takeaway message: the
version comparison for
Debian packages is now
FIXED!
🥳
IMPORTANT: the schema migration might take some hours, depending on the
synced packages and the hardware of your Uyuni server.
