> 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
> OpenJDK JRE 11.0.5
> Reporter: Isabelle Giguere
> Priority: Major
>
> 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:
> {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
> }
> {code}
> Note that I also tried to set java.io.tmpdir to another folder,
> programmatically. That had no effect either. Since the application needs to
> use Tomcat's temp folder for other processing, setting java.io.tmpdir on the
> command line is not an option.
