Isabelle Giguere created TIKA-3203: -------------------------------------- Summary: MP4Parser temporary files are not deleted from Tomcat temp folder Key: TIKA-3203 URL: https://issues.apache.org/jira/browse/TIKA-3203 Project: Tika Issue Type: Bug Components: parser Affects Versions: 1.24.1 Environment: CentOS 7.8 Tomcat webapp Reporter: Isabelle Giguere
In our application, Tika is used as part of a Tomcat webapp. Tomcat sets its temp folder ($CATALINA_HOME/temp) as "java.io.tmpdir". The MP4Parser creates files in java.io.tmpdir. The files created by the MP4Parser are never deleted from temp/. Ex: MediaDataBox10544109451805035303org.mp4parser.boxes.iso14496.part12.MediaDataBox@77cb1ee8 Oddly, there are no errors in logs. Nothing about files that cannot be deleted or not found. Other processes in our application needs to create other files in temp/, so we can't simply delete everything in that folder. I assume from TIKA-1040, TIKA-1361, and TIKA-3084 that most file deletion issues in the MP4Parser have been fixed. This may be a little gremlin in CentOS or in Tomcat ... ? I have tried using TemporaryResources (i.e.: replace the "TikaInputStream.get" in the code below by TikaInputStream.get(InputStream, TemporaryResources)) to put the parser's temporary files in a folder that we can control, but to no avail. Tika's MP4Parser "parse" method initializes a new instance of TemporaryResources, so the TemporaryResources that I created is never used. The default TemporaryResources would use java.io.tmpdir anyways, right? So, why aren't these files deleted ? And, while we are on the subject, there should be a way to set a temporary files folder that parsers actually use (and the parser's dependencies). How can a user-defined TemporaryResources be useful if the parser ignores it ? Relevant code: Parser parser = new AutoDetectParser(); // injected by Spring Path input = ...; // some mp4 audio file Path output = ...; final Metadata metadata = new Metadata(); try(InputStream stream = TikaInputStream.get(input, metadata); OutputStream outputstream = new FileOutputStream(output.toFile()); OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputstream, "UTF-8")){ ParseContext parseContext = new ParseContext(); parser.parse(stream, new BodyContentHandler(outputStreamWriter), metadata, parseContext); // do something with the metadata and the output } -- This message was sent by Atlassian Jira (v8.3.4#803005)
