Bug ID: 64619
Summary: Regression: Removal of scratchdir fallback affects
existing code
Product: Tomcat 8
Version: 8.5.57
Hardware: PC
Status: NEW
Severity: minor
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org
Reporter: sch...@gmail.com
Target Milestone: ----
https://github.com/apache/tomcat/commit/6d7e1a00cd706654eca445989d85960cbfba83ac
assumes, that the scratchdir is always set. But this is not necessarily the
case, especially for tomcat embedded.
Adding this code change in a new mayor release along with an entry in the
changelog/releasenotes wouldn't be a problem.
But adding this change in a minor release, without notice in the changelog and
without a real need (it does not fix a bug or security issue) IS a problem.
Users of Tomcat-embedded should be able to rely on the changelog, such that
applied security fixes can be integrated as fast as possible into the dependent
applications.
Therefore, please don't do unforced refactorings in a minor maintenance
release.
ServletContext is an interface which can have many sorts of implementations. We
use our own implementation of that interface for various reasons. You can not
rely on the assumption, that the Attribute ServletContext.TEMPDIR is always
set.
