+Subject: [PATCH] Print info about obsoleted packages before transaction
+ (RhBug:1855542)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+- Added number of obsolete packages into transaction summary.
+- Added which packages are obsolete and by whom they are replaced.
+
+The user can run microdnf in test mode (--setopt=tsflags=test) to know
+what microdnf will do. However, without this patch, information about
+obsolete (replaced as obsolete) packages was missing.
+
+Example output before patch:
+# microdnf install TestB
+Package Repository Size
+Installing:
+ TestB-1.0.0-1.noarch ci-obsoletes 5,9 kB
+Transaction Summary:
+ Installing: 1 packages
+ Reinstalling: 0 packages
+ Upgrading: 0 packages
+ Removing: 0 packages
+ Downgrading: 0 packages
+Downloading packages...
+Running transaction test...
+Installing: TestB;1.0.0-1;noarch;ci-obsoletes
+Obsoleting: TestA;1.0.0-1;noarch;installed
+Complete.
+
+Example output after patch:
+# microdnf install TestB
+Package Repository Size
+Installing:
+ TestB-1.0.0-1.noarch ci-obsoletes 5,9 kB
+ replacing TestA-1.0.0-1.noarch
+Transaction Summary:
+ Installing: 1 packages
+ Reinstalling: 0 packages
+ Upgrading: 0 packages
+ Obsoleting: 1 packages
+ Removing: 0 packages
+ Downgrading: 0 packages
+Downloading packages...
+Running transaction test...
+Installing: TestB;1.0.0-1;noarch;ci-obsoletes
+Obsoleting: TestA;1.0.0-1;noarch;installed
+Complete.
