Subject: [PATCH] blscfg: Add support for sorting the plus ('+') higher than
|
||
|
|
base version
|
||
|
|
|
||
|
|
Handle plus separator. Concept is the same as tilde, except that if one of
|
||
|
|
the strings ends (base version), the other is considered as higher version.
|
||
|
|
|
||
|
|
A plus character is used for example by the Linux kernel build system to
|
||
|
|
denote that is the base version plus some changes on top of it.
|
||
|
|
|
||
|
|
Currently for example rpmvercmp("5.3.0", "5.3.0+") will return 0 even when
|
||
|
|
the two versions are not the same.
|
||
|
|
|
||
|
