Bug ID: 59139
Summary: undeployOldVersions sorts alphabetically though
version numbers are normally numeric in part
Product: Tomcat 8
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: [email protected]
Reporter: [email protected]
The following function is supposed to identify old applications deployed using
parallel deployment:
org.apache.catalina.startup.HostConfig#checkUndeploy
The application names are qualified with a '##' and a version identifier. This
would often be expected to be numeric. However, comparison is done using a
TreeSet:
// Need ordered set of names
SortedSet<String> sortedAppNames = new TreeSet<>();
This will result in alphabet ordering. 'myApp##9' will be considered newer than
'myApp##10'. This does not seem sensible or intuitive to me.
This can be worked around by ensuring zero padding or otherwise guaranteeing
lexicographical ordering.
