Description Harri Pesonen 2016-11-08 08:49:45 UTC

WAR unpacking creates META-INF/war-tracker file too early after each unpacked file. Noticed this when Tomcat was killed while it was unpacking files. It happily used the partially extracted files, and of course the application did not work anymore.

https://svn.apache.org/repos/asf/tomcat/trunk/java/org/apache/catalina/startup/ExpandWar.java

Here you can see that warTracker file is created inside the unpacking loop, right after each file:

                // Create the warTracker file and align the last modified time
                // with the last modified time of the WAR
                warTracker.createNewFile();
                warTracker.setLastModified(warLastModified);
            }
            success = true;
