PDF and HTML export fails due to 'too many open files' exception

XMLWordPrintable

      Happened while running an export (HTML) on the doc. space on c.a.c..

      Cause:
      java.io.IOException: Too many open files

      This seems to be because we open file input streams, but don't close them!

      An example is:

      FileUtils.copyFile(new FileInputStream(attachmentFile), new File(folder.getAbsolutePath() + "/" + attachmentFile.getParentFile().getName()));

      AbstractRendererExporterImpl:147

      In general, when you don't explicitly close the inputstream, then you will have a file handle leak until the object gets garbage collected.

      Searching for all uses of 'FileInputStream' should be able to show which ones aren't closed

            Verified that fewer than 2000 files can be open concurrently on Windows. Created space with 2500 pages, each with two attachments, one an image which appeared twice in the apge, once thumbnailed.

            Able to export this space as HTML, PDF and XML.

            I thought you guys fixed this? I just had it pop up in both 1.3.5 and 1.4.3 in trying to do an XML export of a space with its attachments. )-:

            And InputStreams in general ....!

            There must have been at least 20 instances in code where we won't closing them!
