I've got several versions of some package. The last of it has an error in %pre section that terminates the install script:
mypak-0.0.1-1.el6.noarch.rpm
mypak-0.0.1-2.el6.noarch.rpm
mypak-0.0.1-3.el6.noarch.rpm <-- bad package
All of my packages have debug output in pre, post, preun and postun sections.
I install the first package:
rpm -ihv mypak-0.0.1-1.el6.noarch.rpm
Output (param is the parameter passed to script sections) is:
Preparing... ########################################### [100%]
pre: 0.0.1-1.el6 ; param = 1
1:mypak ########################################### [100%]
post: 0.0.1-1.el6 ; param = 1
Then I try to update my package and (accidentally) launch rpm command with v2 and v3 packages at once:
rpm -Uhv mypak-0.0.1-2.el6.noarch.rpm mypak-0.0.1-3.el6.noarch.rpm
warning: package mypak = 0.0.1-2.el6 was already added, replacing with mypak > 0.0.1-3.el6
Preparing... ########################################### [100%]
pre: 0.0.1-3.el6 ; param = 2
!!!version 3 is bad!!!
error: %pre(mypak-0.0.1-3.el6.noarch) scriptlet failed, exit status 1
error: install: %pre scriptlet failed (2), skipping mypak-0.0.1-3.el6
preun: 0.0.1-1.el6 ; param = 0
postun: 0.0.1-1.el6 ; param = 0
As you can see, my package was removed in the end. Moreover, the package is removed even if other packages depend on it. I don't even get any warnings about corrupted dependencies!
If I update my packages one after another, I don't have that problem. In this case update to the third version fails and that's all. My package of previous version is still in place.
So my questions are:
I use rpm 4.8.0 on Centos 6.5.
mypak-0.0.1-1.el6.noarch.rpm
mypak-0.0.1-2.el6.noarch.rpm
mypak-0.0.1-3.el6.noarch.rpm <-- bad package

If I update my packages one after another, I don't have that problem. In this case update to the third version fails and that's all. My package of previous version is still in place.
So my questions are:
1. Why do I get different behaviour when I update my package using 'rpm -Uhv 3' and 'rpm -Uhv 2 3'? In the first case only the update fails and my package is not removed. In the second one, the update fails and the package **is** removed.
2. How can my package be removed in that corrupted update transaction if other packages depend on it? If I launch 'rpm -e mypak' it fails as it should:
rpm -e mypak
error: Failed dependencies:
mypak is needed by (installed) mypak-dep-0.0.1-1.el6.noarch
I use rpm 4.8.0 on Centos 6.5.
